Description
Technical field
The utility model relates to the processing tool field, in particular for the clamping tooling of processing thin-walled excircle of workpiece on lathe, and a kind of processing tool that can be used for the thin-walled thread bush of clamping carbon steel material even nylon material thin-walled parts particularly.
Background technology
Thin-walled parts often is widely used in modern designs, and it has many advantages, and is light such as 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 for processing.
For general ordinary carbon steel thin-walled parts, because the wall thickness of part is very thin, produce easily distortion during clamping, and the heat that the 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 material is nylon, want to control well its distortion, just more difficult.By experiment, the nylon thin-walled parts is as adopting the 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 in the utility model provides 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 the processing, further can be used 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 scheme that the utility model adopts is: a kind of processing tool of thin-walled thread bush connects by axle between top cover and the end cap;
Described top cover outer wall is provided with for the first top cover cylindrical wall of confession scroll chuck clamping, is used for the second top cover cylindrical wall that cooperates with the workpiece inwall and the top cover stage that is used for the top tight workpiece end face, the top cover axle center also is provided with the top cover through hole, is provided with locking key between top cover through hole and the axle;
Described end cap outer wall is provided with the end cap cylindrical wall that cooperates with the workpiece inwall and the end cap stage that is used for the top tight workpiece end face, and the end cap axle center also is provided with the 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 the axle end face.
The end cap cylindrical wall of described end cap also is provided with screw thread.
Described axle is equipped with key baffle plate for the axial displacement of restriction locking key near an end end face of top cover by the second fastening bolt.
Also adopt between the top cover through hole of described axle and top cover 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.Control the deflection of part so need the design frock.
This type of thin-walled parts can bar, processes first 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 was threading, wall thickness was very thin, this just brings difficulty to processing.
The processing tool of a kind of thin-walled thread bush that the utility model provides, by adopting above-mentioned structure, provided support by the outer wall of top cover and the end cap inwall to workpiece, and at top cover and end cap the end face that stage is used for spacing workpiece is set, thereby with Workpiece clamping, guaranteed can not produce distortion in the workpiece process, from having controlled to a great extent the deflection of workpiece, the disposable qualification rate of applying for checking and examination of workpiece has been reached about 98%, fundamentally solved the processing difficult problem of nylon material thin-walled thread bush part.
End cap and workpiece internal thread also adopt threaded engagement, and the centre is connected with axle with bolt again, but so both top tight workpieces, again can be by bolt with end cap and axle fixation.The spacer pin that arranges is convenient to transmitting torque.
Top cover and axle adopt being used 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 again the purpose of locking.Thereby can make this frock be applicable to same screw thread specification and the processing of the different workpiece of length.
