Description
Technical field
The invention belongs to precision optical machinery manufacture field, it is special it is standby be a kind of thin-wall rotation-type part cylindrical turning clamping method and
Device.
Background technology
Thin-walled parts processing is the problem of a long-standing problem mechanical processing industry, due to part itself poor rigidity, is being filled
Folder is respectively influenceed part with process by clamping force and Cutting Force easily to be there is elastic deformation and influences machining accuracy, is met not
The requirements of final products.
The outer bowlder of turning slewing parts is most commonly that installation way to there is three-jaw to be used as positioning datum using inner bore of part
Clamping is carried out, part is acted on by radial load.Clamping force, which crosses conference, causes part in ellipse, or even the situation of polygon occurs；
Clamping force is too small to cause part to occur rotating in processing and make part rejection.Another installation way is with zero with plug
Part endoporus carries out clamping as positioning datum pressure side face.But due to thin-walled parts thickness very little, general thickness only has 0.5mm left
The right side, end face can not be pressed, therefore this clamping method does not apply to yet.Therefore, at present in thin-wall rotation-type part cylindrical turning
Crudy is had a great influence by installation way during processing, and clamping dynamics is difficult to control, the problem of causing part deformation or scrap, no
Only machining accuracy is relatively low, and processing percent defective is higher, and processing cost is higher.
The content of the invention
It is an object of the present invention to provide kind of thin-wall rotation-type part cylindrical turning clamping method and a device.The present invention's
Structure is relatively simple, clamping is easy to operate, installation way is reliable, occurs when avoiding thin-wall rotation-type part cylindrical turning processing
Part deformation is scrapped, and not only increases machining accuracy, and reduces processing percent defective, saves processing cost.
Technical scheme：A kind of thin-wall rotation-type part cylindrical turning clamping method, this method are by tightening
Thin-wall rotation-type part endoporus, realize the purpose of thin-wall rotation-type part clamping.
In a kind of foregoing thin-wall rotation-type part cylindrical turning clamping method, methods described is by setting threaded cone
Face push rod and elastic hollow axle, using the relative movement of threaded conical surface push rod and elastic hollow axle, make elastic hollow axle swell
Thin-wall rotation-type part endoporus is tightened, the purpose of thin-wall rotation-type part clamping is realized, avoids thin-wall rotation-type part
Irregular deformation.
In a kind of foregoing thin-wall rotation-type part cylindrical turning clamping method, the elastic hollow axle is by threaded
Conical surface push rod moves, and the inner conical surface of elastic hollow axle is moved on the male cone (strobilus masculinus) of threaded conical surface push rod, so that elasticity is empty
Mandrel swell tightens part thin-wall rotation-type part endoporus.
Clamping device used in a kind of foregoing thin-wall rotation-type part cylindrical turning clamping method, including base, elasticity
Hollow shaft and threaded conical surface push rod, base center are provided with pilot hole, and pilot hole is threadedly coupled with threaded conical surface push rod, elasticity
Hollow shaft is located at threaded conical surface push rod periphery.
In foregoing clamping device, the threaded conical surface push rod includes thread segment, conical surface section and push rod section, the screw thread
Section, conical surface section and push rod section are sequentially connected setting；The threaded conical surface push rod is led by thread segment with what base center was set
Connected to hole；The elastic hollow axle is located at conical surface section periphery.
In foregoing clamping device, outside the conical surface section of the inner conical surface taper of the elastic hollow axle and threaded conical surface push rod
Conical degree of conical surface is consistent.
Compared with prior art, the present invention turns round class by using the mode for tightening thin-wall rotation-type part endoporus to thin-walled
Part carries out clamping, thin-wall rotation-type part is carried out clamping uniform force, avoids thin-wall rotation-type part and sent out in clamping
Change shape, while installation way is reliable and stable, and avoiding thin-wall rotation-type part can cause in processing because clamping force is too small
Parts turn and there is the problem of part rejection；Specifically, the present invention passes through in the whole cylindrical and part of elastic hollow axle
Hole contacts, and avoids caused by clamping reason thin-walled parts from producing irregular deformation, secondly as elastic hollow axle it is whole it is cylindrical with
Inner bore of part contacts, and greatly strengthen part rigidity, can avoid causing part because Cutting Force causes part elastic deformation during turning
Variable thickness causes, and improves the precision of part processing.In summary, structure of the invention is relatively simple, clamping is easy to operate, dress
Folder mode is reliable, occurs part deformation when avoiding thin-wall rotation-type part cylindrical turning processing or scraps, not only increases and add
Work precision, and processing percent defective is reduced, save processing cost.
