Abstract
The invention discloses a fixture for cylindrical turning of a thin-walled part. The fixture comprises a spindle, a pressure head, a pull rod, an expansion sleeve and a plurality of pressure pins; the center of the spindle is provided with a fixing hole which penetrates the spindle; the lower end of the spindle is provided with a positioning hole which is connected with a lathe shaft disk; the upper end of the spindle is provided with a channel for the pressure pins to slide in; the fixing hole sleeves the pressure head; the upper end of the pressure head is provided with a boss; the lower end of the pressure head is in threaded connection with the pull rod; the expansion sleeve is formed by liquid plastic and located below the pressure pins; the expansion sleeve comprises an expansion portion and a fixing portion; the fixing portion of the expansion sleeve is embedded in the spindle; the upper end of the fixing portion of the expansion sleeve abuts against the lower end of every pressure pin; the upper end of every pressure pin is located below the boss of the pressure head. During thin-walled part clamping, the force of thin-walled parts is uniform, the deformation is not produced, and accordingly the machining accuracy of the thin-walled parts is improved and the machining requirements are met.
Description
Technical field
The present invention relates to part manufacture field, a kind of thin-wall part turning of specific design fixture.
Background technology
Thin-wall part is because have lightweight, feature such as saving material, compact conformation etc., and thin-wall part is applied in every field increasingly extensively.But the processing of thin-wall part is more thorny, reason is that thin-wall part poor rigidity, intensity are weak, and the as easy as rolling off a log distortion of work in-process, not easily ensures the crudy of part; The machining accuracy how improving thin-wall part will be the topic that industry is more and more concerned about.
In current machining industry, be all adopt processing thin-walled of spring steel ringfeder, during due to spring steel ringfeder clamping thin sheet wall pieces, thin-wall part unbalance stress, cause thin-wall part to be out of shape comparatively large, machining accuracy is not high, cannot reach requirement.
Summary of the invention
The invention is intended to provide a kind of thin-wall part turning fixture, to improve thin-wall part machining accuracy.
Thin-wall part turning fixture in this programme, comprise axle, pressure head, pull bar, ringfeder and multiple compression pin, spindle center is the fixing hole running through axle, axle lower end is provided with the locating hole be connected with lathe reel, axle upper end is provided with the passage for compressing pin slip, pressure head is enclosed within fixing hole, pressure head upper end is provided with boss, pressure head lower end is connected with pull rod screw, ringfeder is that liquid plastics is made, ringfeder is positioned at and compresses pin below, ringfeder comprises swelling portion and fixed part, ringfeder fixed part is embedded in axle, the upper end of ringfeder fixed part is against the lower end compressing pin, the upper end compressing pin is positioned at below pressure head boss.
Compared with prior art, the invention has the advantages that: comprise axle, pressure head, pull bar, ringfeder and multiple compression pin, spindle center is the fixing hole running through axle, axle lower end is provided with the locating hole be connected with lathe reel, axle upper end is provided with the passage for compressing pin slip, compressing pin is distributed in axle, pressure head is enclosed within fixing hole, pressure head upper end is provided with boss, pressure head lower end is connected with pull rod screw, ringfeder is that liquid plastics is made, ringfeder is positioned at and compresses pin below, ringfeder comprises swelling portion and fixed part, during ringfeder swelling portion's forced expansion, can evenly be filled in thin-wall part endoporus, make thin-wall part uniform force, and due to liquid plastics ringfeder natural resiliency, liquid plastics ringfeder is made to have adaptive ability, can automatic centering, ringfeder fixed part is embedded in axle, and the upper end of ringfeder fixed part is against the lower end compressing pin, and the upper end compressing pin is positioned at below pressure head boss, pull bar pulls pressure head, pressure head acts on and compresses on pin, compresses pin and pushes against ringfeder fixed part downwards, and then makes the fixing thin-wall part of ringfeder swelling portion expansion, pull bar reverse push dynamic head, compress pin and no longer exert a force at ringfeder fixed part, ringfeder replys original state, can thin-wall part be taken off, during clamping thin sheet wall pieces of the present invention, thin-wall part uniform force, can not distortion be produced, thus improve the machining accuracy of thin-wall part, reach processing request.
Further, mandrel channels upper end is provided with counterbore, and counterbore and compression are provided with spring between selling, and compress pin and be provided with spring fixed seat, spring plays the effect that pin is resetted.
Further, counterbore top is provided with sealing ring, prevents dust etc. from entering counterbore, causes compressing selling wearing and tearing, and impact compresses the quality of fit of pin and passage.
Further, compress pin and have six, circumference is distributed in axle, and pressure head force is more even, ensures multiple compression pin uniform force, makes its even inflation, swelling thin-wall part simultaneously to liquid plastics ringfeder force.
Accompanying drawing explanation
Fig. 1 is the structural representation of the embodiment of the present invention.
Detailed description of the invention
Below by detailed description of the invention, the present invention is further detailed explanation:
