Description

Spinning is used clamping device
Technical field
The utility model relates to a kind of apparatus for fastening, relates in particular to a kind of spinning and uses clamping device.
Background technology
Spinning is that flat board or hollow blank are fixed on the mould of spinning machine, when blank rotates with the lathe main shaft, with spinning roller or catch up with rod to stress on blank, makes it to produce local plastic deformation.Under the acting in conjunction that rotatablely moves of the feed motion of spinning roller and blank, make local plastic deformation expand to all surfaces of blank step by step, and be close to mould, accomplish the rotary pressing processing of part.The advantage of rotary pressing processing is equipment and mold all fairly simple (can not replace with lathe when having special-purpose spinning machine); Except that the rotary body that can be shaped, also can process the rotary body part of suitable complicated shape like cylindrical shape, taper, parabolic formation or other various curves formations.Rotary pressure technology has obtained application more and more widely now as a kind of low cost, high efficiency part forming technology.When carrying out mould pressing, need spinning to fix processed part with clamping device, spinning is one of critical component of spinning machine with clamping device, is directly connected to the processing characteristics of lathe.The thin-walled pipe part is one of main processing object of mould pressing, and when processing thin-walled pipe part, existing spinning is little with the clamping force of clamping device, influences workpiece accuracy.Existing in addition spinning only is an end that grasps the thin-walled pipe part with clamping device, and insufficient rigidity when causing thin-walled pipe part spinning is easily damaged when spinning, scraps.
Summary of the invention
Problem to above-mentioned prior art existence; The utility model provides a kind of spinning to use clamping device; The problem of insufficient rigidity in the time of can effectively solving thin-walled pipe part spinning, and load and unload convenience easy to maintenance, can process the workpiece of various calibers; Its clamping force is big in addition, and is very practical.
The technical scheme of the utility model is: a kind of spinning is used clamping device, comprises some jaws and jaw installation sleeve, and jaw circumferentially is arranged at intervals at a wherein end of jaw installation sleeve along the jaw installation sleeve; Jaw surfaces is socketed with the jaw gland; The jaw gland cooperates with the jaw inclined-plane, and the jaw gland is provided with thrust ball bearing away from an end of jaw, and thrust ball bearing is outside equipped with outer shroud; Be provided with guide pillar between jaw and the jaw installation sleeve, be socketed with disk spring on the guide pillar; The jaw installation sleeve is removably connected with the workpiece support ring near the end face of jaw, leaves the gap between the working face of workpiece support ring and jaw; Jaw installation sleeve, jaw gland and jaw surfaces are respectively arranged with the fiberglass anticorrosive coat.
As preferably, be removably connected with fixture block on the working face of jaw.
As preferably, thrust ball bearing is outside equipped with the exoskeletal rubber oil sea of J type.
As preferably, said jaw is 8.
As preferably, the inclined-plane of jaw is provided with convexity, has on the inclined-plane of jaw gland and the protruding groove that cooperates.
The beneficial effect of the utility model is: the utility model connects hydraulic cylinder, by the Driven by Hydraulic Cylinder outer shroud, promotes the jaw gland through thrust ball bearing and compresses jaw, thereby make jaw clamping work pieces blank, and clamping force is big.Can pressure sensor on the hydraulic circuit, make fastening safety reliable.During spinning, the workpiece blank slit between fixture block and the workpiece support ring of packing into, with the end face location of jaw installation sleeve, the workpiece support ring is used to support the endoporus of thin-walled pipe part, makes part when spinning, have enough rigidity.Through the physical dimension of adjustment fixture block and workpiece support ring, can process the workpiece of various calibers, very convenient.The loading and unloading of the utility model convenience easy to maintenance is suitable for other lathes and uses in addition, and is very practical.
