Abstract
The invention discloses a thin wall processing fixture, comprising a locating sleeve, a fixing sleeve and a mandrel; the locating sleeve is installed on a chuck, and a fixing hole with threads is processed at the centre of the inner side of the locating sleeve; a holding groove used for fixing a thin wall workpiece is arranged at the centre of the fixing sleeve, and the section of the fixing sleeve is U-shaped; a through hole is also arranged at a position on the bottom part of the holding groove at the centre of the fixing sleeve; the fixing sleeve is inserted in the fixing hole, and a thread matched with the fixing hole is arranged at a position at one end of the holding groove on the fixing sleeve; a thread matched with the fixing hole is arranged at the front end of the mandrel, the back end of the mandrel is inserted in the workpiece and is used for fixing the workpiece. The thin wall processing fixture of the invention not only guarantees the coaxiality of the excircle and the inner hole of the workpiece, but also avoids the workpiece deformation during finish machining and improves the workpiece processing precision and the workpiece quality.
Description
Technical field
The present invention relates to a kind of anchor clamps, especially a kind of anchor clamps of processing thin-walled workpiece belong to machining and use the clamping device technical field.
Background technology
For the processing of some pipe parts, after the roughing, often when fine finishining, can cause a large amount of scrappages.This is because the tube wall of such part is very thin, have in addition have only two or three millimeters, for fear of the distortion of workpiece, when fine finishining, all adopt grinding.The outside that generally is again workpiece puts an opening sleeve, has so just avoided the direct clamping work pieces of chuck, and has made workpiece deformation.But generally with once just being out of shape, when especially grinding endoporus, the workpiece Internal Hole Deformation that processes is very serious for opening sleeve.Moreover, now during this type of fine finishining thin-wall workpiece, mill endoporus and processing excircles; All adopt two sleeve clamps to process, anchor clamps are on being fixed to chuck the time, and the axiality of anchor clamps and chuck all can have deviation; The workpiece that processes like this, the axiality of its cylindrical and endoporus also has very big error, causes scrapping of workpiece; Both waste time and manpower, also wasted the wide variety of materials cost.
Summary of the invention
Technical problem to above-mentioned existence the objective of the invention is: proposed a kind of thin-walled clamp for machining, it can guarantee the axiality of excircle of workpiece and endoporus, deforms when avoiding the workpiece grinding simultaneously.
Technical solution of the present invention is achieved in that a kind of thin-walled clamp for machining, comprises positioning sleeve, fixed cover and mandrel; Said positioning sleeve is installed on the chuck, and has threaded fixing hole in the heart in the inboard of positioning sleeve; The center of said fixed cover has the fixedly storage tank of thin-wall workpiece, and the cross section of fixed cover takes the shape of the letter U; In the heart, the bottom that is positioned at storage tank also has through hole in the said fixed cover; Said fixed cover inserts in the fixing hole, and on the fixed cover, an end that is positioned at storage tank is provided with the screw thread that matches with fixing hole; The front end of said mandrel is provided with the screw thread that matches with fixing hole, and insert in the workpiece rear end, and fixation workpiece.
Preferably, the diameter of said through hole is greater than inner diameter of workpiece, less than the external diameter of workpiece.
Preferably, said fixing hole is a T shape counterbore, and is made up of first fixing hole and second fixing hole; Said first fixed hole position is in the outside, and fixed cover is threaded; Said second fixed hole position is in the inboard, screw thread fixed central spindle.
Preferably, said mandrel is " ten " font, and front end is fixed in second fixing hole, and vertically extending position is stuck in first fixing hole on the mandrel.
Because the utilization of technique scheme, the present invention compared with prior art has advantage:
Thin-walled clamp for machining of the present invention adopts same positioning sleeve and the fixed cover, the mandrel of processing excircles of processing endoporus that is fixed on the chuck; Finish grind workpiece; Both guarantee the axiality of excircle of workpiece and endoporus, and also avoided workpiece when fine finishining, to deform, improved the quality of workpiece machining accuracy and workpiece; Also improve working (machining) efficiency greatly, reduced the scrappage of workpiece.
