General accuracy machine tool processes chamfer of annulus of the coaxial inside aperture and unit of the end panel that turn over Huo

Summary: The treatment of the machine tool is the serious content that the enterprise produces all the time, there are a lot of meanses and device method in the treatment device of the machine tool, the article machines the means of a few kinds of device of chamfer of annulus of the coaxial inside aperture and device of the end panel that turn over Huo to make clear divisional general accuracy machine tool, basically analyse construction of 3 kinds of plant and working principle, the hope can be mixed to the production of the product the device of the machine tool is optimized inspire somewhat. Keyword: The plant process that coaxial annulus chamfer turns over machine tool of foreword of device of Huo end panel inside aperture of general accuracy machine tool and working principle are the main field that the machine tool produces all the time, it is especially in the product production of higher administrative levels, often can appear relevant technical difficult point, the article cuts unit of chamfer of aperture core form in research and analytic radial, but on the foundation of device of chamfer of form of the axial shift, radial core that cut hole and the unit that have side of the Kong Duan that turn over Huo, have the plant construction that specific aim ground is optimized and adjusts a machine tool, the setting cuts chamfer of aperture core form device and cut Kong Neikuan the special unit of annular chamfer, the hope can produce effect to machine tool production. The working characteristic of 3 kinds of 1 　 , device and principle are common those who get the production that cuts kind of machine tool to move in order to assure radial in the absense of relevant dynamical component is normal begin, the treatment that can bring about a product goes against production. If the graph is shown 1 times inside aperture is annular groove and aperture end panel do not suit very much, below this kind of circumstance, pass connection only implement (sleeve blocks a head) with auger, the interaction of boring machine, achieve the goal that is linked together with main shaft finally, radial to making sure cutting cutting tool is coinstantaneous shift and the athletic contrail with mobile axial have very big effect, those who assure spare parts aperture is medium grooving and the manufacturing process that turn over Huo aperture end panel are able to finish quickly. Graph 1 inside chamfer of Kong Huan form and aperture end panel machine sketch map 　 1.

Device of chamfer of form of the 1 radial core that cut hole from the graph 2 in can see, this device applies to the annular chamfer with narrower cutting, if pursue 1 in (A) be shown, the treatment means of this kind of type suits to machine a few like casing kind the treatment of the coaxial annulus chamfer material inside spare parts aperture. With drilling machine treatment is exemple, explanation and introductory radial cut the working principle of device of chamfer of aperture core form. Pass sleeve, make drilling machine main shaft drives device of chamfer of form of the core that cut hole to work. Its job process is to should produce the main unit in equipment to be in as the machine tool when main shaft is forward, the slippery lever in equipment and grooving knife and arbor also are in likewise as equipment medium main shaft direction does identical axial shift and the whirligig that circle axes. Follow-up work is the working program of grooving knife, when grooving knife obtains the position that has acquiesced ahead of schedule, the main shaft of whole production facilities can move ahead as the axis of equipment. Different is, among them slippery lever and grooving knife won't produce similar action as the main shaft of equipment, continue to stop to be in however appropriate position, the process is here medium, arbor can have change, arbor still can continue to move again along the axis, the effect of such generation is pair of slippery lever and arbor generation action, the position that produces certain level is mobile, produce effect to the tool production of whole equipment thereby, come so, the effect that produces machines the effect that has treatment production to the cutting of chamfer of aperture core form. In its job principle, often can produce relevant difference situation, it is especially in the mobile process of equipment, slippery lever and arbor produce effect, can make silk is blocked up stem bedspring, after annular inside aperture chamfer machines a process to end, make the main shaft go back of equipment arrives most begun position. Arbor also can be retreated return first place, await the operation that leaves one round. Slippery lever won't return first place, make arbor and slippery lever produce relevant mobile effect, in order to preparing the next time manufacturing process, right now the whole production process of grooving just ends. Graph 　 of device of chamfer of form of the 2 core that cut hole 1.

The process of 2 axial and unit of radial and mobile chamfer of form of the core that cut hole is in effective treatment process, can appear the circumstance with relevant improper measure, the circumstance that if the chamfer of chamfer of aperture core form is wide,the oneself broad measure of dimension and grooving knife nots agree with, when encountering this kind of situation, want distinction to treat. The groovy broad measure of the chamfer of aperture core form that is less than place to need to machine when the oneself width of grooving knife (if pursue 1 (B) be shown) when, graph the requirement that 2 medium device cannot satisfy treatment, want a basis to pursue so the plant construction of 2 tries to alter and be adjusted, in order to satisfy the treatment requirement that the product of wide annular chamfer inside this kind of aperture produces, the course is adjusted and optimize, the structural unit that receives finally is shown 3 times like the graph, in the structure of this kind of device after alter, the cutting tool in equipment is in use process, make radial shift first, again axial is mobile, the production that satisfies width and different product thereby machines a requirement, implementation machines Kong Neikuan along groovy broad direction annular chamfer. Graph 3 medium plant constructions basically are to machine Kong Neikuan annular chamfer and the setting with special design, it is to the graph 2 device cannot satisfy what the treatment of wide annular chamfer inside aperture asks to improve. The working limits of the equipment unit after adjusting arrives at a requirement to be able to satisfy a product to machine axial position of groove from cutting tool position of rest, the treatment process that satisfies radial grooving motion in the in machining a process need of real product, its job principle is cutting tool of the treatment on the foundation that moves with cutting tool, slide lever produces positional shift in the hole of arbor, this kind of shift can lay next foundations for radial motion, finish whole grooving to process the work thereby. Its different point depends on: In the graph in the plant equipment of 3, after grooving knife reachs treatment work place of the regulation, the mobile contrail of machine tool main shaft produces change, continue to go backwards backward no longer, continue to move ahead along main shaft however, make small bedspring is come from the pressure of machine tool main shaft, the athletic contrail that brings about whole grooving knife produces change, it is retrogression no longer, continue to work along main shaft however, assure whole work program thereby finish. After working program is finished, big bedspring begins to send force, make whole grooving knife is in mobile process, go back arrives first working place, await the working course that leaves one round. Graph 3 cut the special unit 　 of wide annular chamfer inside aperture 1.

The 3 equipment unit that include end panel of the aperture that turn over Huo the working principle of two kinds of device is realize feed of cutting tool radial for the foundation with principle of oblique plane drive, device of chamfer of form of the radial core that cut hole and but the athletic contrail of the cutting tool in device of chamfer of form of the axial shift, radial core that cut hole is like a graph respectively 4 (A) , (B) be shown, when the demand of the surface of aperture end panel that machines when need is not high, the plant that shows among them and working structure can be satisfied and apply at aperture inside groovy treatment, can satisfy treatment of the chamfer inside aperture not only, and the end panel treatment that can be satisfied at aperture. But in actual working process, often can appear the circumstance that cutting tool cut already machined the surface, to prevent this kind of situation, install another measure with respect to need, allow knife movement, after this measure is added, graph 2, graph 3 in 2 shows plant no longer appropriate at machining aperture inside the end panel of groove and aperture. In cutting tool not below the circumstance of go back, if the athletic contrail of cutting tool pursues 4 (C) be shown, in cutting tool fore-and-aft after the place that reachs cutting end panel, athletic contrail can produce change, begin to transfer radial athletic pattern, after the cutting of end panel is finished, can adjust an axial campaign, what this wants achieved movement letting a knife namely, after whole process letting a knife ends, cutting tool begins withdrawal of instead radial shift, in order to achieve the ultimate goal of go back of implementation axial shift. Adopt a plan 4 in (B) , (C) more knowable, alter on the foundation of the equipment unit of 3 and adjust in the graph only, the structure that if the graph is shown 5 times,just can achieve finally, satisfy motion letting a knife, reach a figure thereby 4 (C) contrail of shows cutting tool motion. Graph the 5 unit that have orgnaization letting a knife from the graph 5 can see, the structural design of its device can complete exercise letting a knife on the foundation of cutting end panel, implementation turns over Huo and let a knife namely. When the radial shift that when the graph 5 shown equipment unit pass cutting tool implements the cut of end panel, the small bedspring that goes up to nut undertakes trying pressing going up, on the foundation of the axial shift process of machine tool main shaft, the compression that place of small stage clip suffers force increases, can make the axial that cutting tool undertakes another round moves, what can assure motion letting a knife thereby is all finish, in this one process card claw passes the action deciding case in fixed position bedspring, can circle to circumgyrate along the axis, in blocking ungual card to enter calorie of chamfer, make the motive be no longer in force of bedspring; After whole job letting a knife is finished, main shaft can go backwards along the axis, at this moment the end panel cutting tool of whole equipment can do exercise of radial go back, install the link stopper on arbor to have tip blocking claw, small stage clip produces action to fall right now, cutting tool is stagger the shift of the distance that lets a knife, next all arbor is retreated together along with main shaft return first place, in order to await new round motion. 2, 3 kinds of device in the article can finish epilogue the treatment of end panel of chamfer of aperture core form, Huo and Huo aperture form, the lot that contented machine tool produces produces demand. Construction of 3 kinds of plant simple, cost low, operation is convenient, while general accuracy machine tool and the special machine tool that batch manufactures can realize poriferous annulus chamfer and end panel, machine, and the operation is simple, of special machine tool complex and trival. 3 kinds of device are had stronger practical, can bring good economic benefits.
