Description
Technical field
The present invention relates to processing tool field, in particular for the clamping tooling of processing thin-walled excircle of workpiece on lathe, particularly a kind ofly can be used for clamping the even processing tool of the thin-walled thread bush of nylon material thin-walled parts of carbon steel material.
Background technology
Thin-walled parts is often widely used in modern designs, and it has many advantages, as light in quality, easy to assembly etc., all plays in a lot of fields irreplaceable effect.But, thinner just because of its outer wall shape, so also bring many technical barriers to processing.
For general ordinary carbon steel thin-walled parts, because the wall thickness of part is very thin, during clamping, easily produce distortion, and the heat that lathe tool smear metal produces is also influential to part, so overproof situation appears in accessory size after can causing completion of processing.And for the thin-walled parts that is nylon for material, want to control well its distortion, just more difficult.By experiment, nylon thin-walled parts is as adopted commonsense method clamping, and the qualification rate of part is less than 5%, and scrappage is very high.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of processing tool of thin-walled thread bush, can realize easily the clamping of thin-walled parts, avoid the distortion in clamping and processing, further can be for clamping inner wall shape and screw thread model just as, but the different workpiece of length.
For solving the problems of the technologies described above, the technical solution adopted in the present invention is: a kind of processing tool of thin-walled thread bush, connects by axle between top cover and end cap;
Described top cover outer wall is provided with for the first top cover cylindrical wall for scroll chuck clamping, for the second top cover cylindrical wall of coordinating with workpiece inwall with for the top cover stage of top tight workpiece end face, top cover axle center is also provided with top cover through hole, between top cover through hole and axle, is provided with locking key;
Described end cap outer wall is provided with the end cap cylindrical wall that coordinates with workpiece inwall and for the end cap stage of top tight workpiece end face, end cap axle center is also provided with end cap blind hole, and the blind hole end of end cap blind hole is connected with spacer pin by the first fastening bolt with axle end face.
The end cap cylindrical wall of described end cap is also provided with screw thread.
Described axle is provided with for limiting the key baffle plate of the axial displacement of locking key by the second fastening bolt near one end end face of top cover.
Between the top cover through hole of described axle and top cover, also adopt and be threaded.
For thin-walled parts, Thin-wall Nylon Parts especially, if do not adopt frock, the scrappage of part is very high.Analyze reason and be mainly following three aspects: 1, large, the wall thickness of diameter of part; 2, material is nylon, and quality is soft, and elasticity is large, heat radiation is slow; 3,, during smear metal, the heat that lathe tool produces causes nylon jacket to produce expanding with heat and contract with cold, cause internal and external screw thread defective.Therefore need design frock, control the deflection of part.
This type of thin-walled parts can bar, first processes each size of endoporus, each size of reprocessing cylindrical.Processing during endoporus wall ratio thicker, generally only should be noted and control rotating speed, the amount of feeding and cooling fluid well, difficulty of processing is little, when key is threading, wall thickness is very thin, this just brings difficulty to processing.
The processing tool of a kind of thin-walled thread bush provided by the invention, by adopting above-mentioned structure, outer wall by top cover and end cap provides support the inwall of workpiece, and stage is set on top cover and end cap for the end face of spacing workpiece, thereby by Workpiece clamping, guaranteed can not produce distortion in workpiece process, from having controlled to a great extent the deflection of workpiece, make the disposable qualification rate of applying for checking and examination of workpiece reach 98% left and right, fundamentally solved a processing difficult problem for nylon material thin-walled thread bush part.
End cap and workpiece internal thread also adopt threaded engagement, and centre is connected with axle with bolt again, so both can top tight workpiece, and again can be by bolt by end cap and axle fixation.The spacer pin arranging is convenient to transmitting torque.
Top cover and axle adopt being used in conjunction with of screw thread and key, and this structure both can reach by screw thread rotation the use length of adjusting tool, can reach by locking key the object of locking again.Thereby can make this frock be applicable to same screw thread specification and the processing of the different workpiece of length.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the invention will be further described:
Fig. 1 is the overall structure schematic diagram while adopting clamping workpiece of the present invention.
Fig. 2 is the cutaway view of top cover in the present invention.
Fig. 3 is the cutaway view of end cap in the present invention.
In figure, top cover 1, the first top cover cylindrical wall 11, top cover stage 12, the second top cover cylindrical wall 13, top cover keyway 14, top cover through hole 15, workpiece 2, end cap 3, end cap stage 31, end cap cylindrical wall 32, end cap blind hole 33, the first fastening bolts 4, locking key 5, key baffle plate 6, the second fastening bolts 7, axle 8, scroll chuck 9, spacer pin 10.
The specific embodiment
