Abstract
A kind of jig for processing thin-wall sleeve type parts, there is a holder be connected with main shaft, holder has centre bore, separately there is one with the mobile tapered sleeve of endoporus, mobile tapered sleeve is made up of the undergauge cylindrical section of front and back and the conical section at middle part, the rear portion cylindrical section of mobile tapered sleeve is inserted in the isometrical centre bore of holder, the pyramidal portion periphery of mobile tapered sleeve arranges that the wedge mated with tapering rises block, wedge rises between block base and holder and is lined with annulus pad, the cylindrical section cover of mobile tapered sleeve front portion has the gland linked together with holder, holder front end and gland arrange the spring pressuring plate that the end of rising by block to wedge inwardly compresses, there is the extension bar be connected with main shaft draw-in bar, extension bar is fixed through the centre bore of holder and mobile tapered sleeve.The utility model utilizes workpiece lumen self-centering clamping, and wedge rises block and mobile tapered sleeve rigid contact self-locking, and there is not elastic deformation, make accurate work piece positioning, especially for the workpiece that some inner chambers are elongated, the rigidity of this fixture and stability are extremely outstanding.
Description
Technical field
The utility model relates to a kind of jig for processing thin-wall sleeve type parts, is applicable to clamping housing, dish cover class, processes with the part of inner chamber location.
Background technology
Conventional thin-wall sleeve parts fixture, its fastening is the elastic deformation utilizing expander, and the material manufacturing fixture expander is 65Mn, and after heat treatment, its distortion is uncontrollable, cause yield rate low, processing cost is high, and fixture finished product life cycle is short, after a long time use, because its internal stress discharges, expander is out of shape, and causes prototype clamp precision to decline, even scraps.
Summary of the invention
The purpose of this utility model is to provide a kind of jig for processing thin-wall sleeve type parts, changes the mode that original fixture clamps in elastic deformation mode, avoids the defect that yield rate is low, life cycle is short using elastomeric material to cause.
The purpose of this utility model realizes as follows: have a holder be connected with main shaft, holder has centre bore, separately there is one with the mobile tapered sleeve of endoporus, mobile tapered sleeve is made up of the undergauge cylindrical section of front and back and the conical section at middle part, the rear portion cylindrical section of mobile tapered sleeve is inserted in the isometrical centre bore of holder, the pyramidal portion periphery of mobile tapered sleeve arranges that the wedge mated with tapering rises block, wedge rises between block base and holder and is lined with annulus pad, the cylindrical section cover of mobile tapered sleeve front portion has the gland linked together with holder, holder front end and gland are arranged wedge is risen the spring pressuring plate that block inwardly compresses, there is the extension bar be connected with main shaft draw-in bar, extension bar is fixed through the centre bore of holder and mobile tapered sleeve.As the supportive body of work piece after holder is connected with main shaft, extension bar drives mobile tapered sleeve axially to move inwards, forces the wedge block that rises to move radially, achieve clamping function, mobile tapered sleeve is axially outwards mobile, and spring pressuring plate compressing wedge rises block playback, realizes release function.
Extension bar is through the endoporus of mobile tapered sleeve, and extension bar has the boss withstanding on mobile tapered sleeve rear end, and extension bar nose threads part is rotary with the locking nut compressing mobile tapered sleeve front end.
Dust ring is provided with between the cylindrical section outer peripheral face of mobile tapered sleeve front portion and gland endoporus.
The utility model utilizes workpiece lumen self-centering clamping, and wedge rises block and mobile tapered sleeve rigid contact self-locking, and there is not elastic deformation, make accurate work piece positioning, especially for the workpiece that some inner chambers are elongated, the rigidity of this fixture and stability are extremely outstanding.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention
With reference to Fig. 1, there is a holder be connected with main shaft 1, holder 1 has centre bore, separately there is one with the mobile tapered sleeve 6 of endoporus, mobile tapered sleeve 6 is made up of the undergauge cylindrical section of front and back and the conical section at middle part, the rear portion cylindrical section of mobile tapered sleeve 6 is inserted in the isometrical centre bore of holder 1, the pyramidal portion periphery of mobile tapered sleeve 6 arranges that the wedge mated with tapering rises block 4, wedge rises between block 4 base and holder 1 and is lined with annulus pad 2, the cylindrical section cover of mobile tapered sleeve 6 front portion has the gland 9 linked together with holder 1, dust ring 8 is provided with between cylindrical section outer peripheral face and gland 9 endoporus, holder 1 front end and gland 9 are arranged wedge is risen the spring pressuring plate 5 that block 4 inwardly compresses, there is the extension bar 3 be connected with main shaft draw-in bar, extension bar 3 is through the endoporus of mobile tapered sleeve 6, extension bar 3 has the boss withstanding on mobile tapered sleeve 6 rear end, extension bar 3 nose threads part is rotary with the locking nut 7 compressing mobile tapered sleeve 6 front end.Extension bar 3 is connected with main shaft draw-in bar, and make its axially inwardly motion by folded spring, mobile tapered sleeve 6 lead holder 1 in, axially under extension bar 3 drives moves inwards, and wedge rises block 4 and mobile tapered sleeve 6 rigid contact, radially outward moves, realizes clamping function; Knife striking cylinder promotes main shaft draw-in bar, folded spring compression, and extension bar 3 is outwards motion axially, and mobile tapered sleeve 6 is axially outwards mobile, and spring pressuring plate 5 forces the wedge block 4 that rises to playback, and realizes release function.
