Firstly, the fixing sleeve is separated from the clamping base, a workpiece is arranged in the clamping pipe, then the clamping pipe is arranged in the large hole of the step blind hole, the fixing sleeve is connected with the clamp base, the fixing sleeve and the clamp base are further screwed, and the workpiece can be clamped tightly. After the workpiece is installed, the tail of the clamp base is arranged in a main shaft hole of a lathe, and an inner hole of the workpiece can be turned; after the workpiece is machined, the fixing sleeve is separated form the clamp base, and the workpiece and the clamping pipe can be pulled out by the spring.
Description
Technical field
The utility model relates in turning processing for the fixture of clamping workpiece, and specifically a kind of to Thin-walled Aluminum matter inner bore of part, turning adds the fixture adopted man-hour.
Background technology
At present, processing for endoporus on the column part adopts turning processing usually, add and adopt man-hour chuck by Workpiece clamping in turning, for processing the thinner part of interior rear wall thickness, can there is following problem: be that some is stressed, stressed even not for outer surface of workpiece owing to clamping, yielding during clamping, while after processing endoporus, taking off part, because deformation recovers to some extent, and then can affect the endoporus machining accuracy.The problems referred to above are particularly evident for aluminium matter part.In addition, in turning processing, adopt chuck to clamp workpiece, need to adjust the axiality of workpiece and lathe spindle in clamping process, the speed of clamping workpiece is slower, affects operating efficiency.
The utility model content
The purpose of this utility model is to provide a kind of Thin-walled Aluminum matter inner bore of part turning clamp, adopt the distortion after this fixture can reduce part processing, and the efficiency of clamping workpiece can be improved.
For achieving the above object, the utility model adopts following scheme: Thin-walled Aluminum matter inner bore of part turning clamp, it has a fixed cover and a clamping fixture seat, there is cavity in fixed cover, the front end of fixed cover and rear end have through hole and the screwed hole communicated with its cavity, clamping fixture seat is connected as a single entity and forms with the afterbody that is Rotary-table by being cylindrical head, this tapering of afterbody that is Rotary-table is identical with the tapering of lathe main axis hole, the head of clamping fixture seat has external screw thread, screwed hole on fixed cover connects with the external screw thread of clamping fixture seat head, the head of clamping fixture seat has the ladder blind hole, the macropore of this ladder blind hole is truncated cone-shaped, the pinch tube be mated is housed in the macropore of this ladder blind hole, have the open slot more than two on the tube wall of pinch tube, one spring is housed in the ladder blind hole.
From such scheme, during the fixture that uses the utility model to provide, first fixed cover and clamping fixture seat are separated, workpiece is packed in pinch tube, again pinch tube is contained in the macropore of ladder blind hole on clamping fixture seat, then fixed cover is connected with clamping fixture seat, fixed cover and clamping fixture seat are being relatively rotated, in the process that both are further screwed, can be by pinch tube by Workpiece clamping; After the workpiece installation, then the afterbody that the clamping fixture seat rear portion is Rotary-table is packed in the spindle hole of lathe, after completing the installation of fixture, can carry out endoporus turning processing to workpiece.After workpiece machines, then fixed cover is separated with clamping fixture seat, workpiece and pinch tube can, by spring ejection, can then be installed processing to next workpiece.
The utility model is simple and reasonable for structure, and its clamping workpiece is convenient, reliable, and it on lathe spindle, install convenient, position error is little, it can improve machining accuracy, can improve working (machining) efficiency again.
The accompanying drawing explanation
The structure that Fig. 1 is the utility model one embodiment and use view.
The structural representation that Fig. 2 is pinch tube in the utility model one embodiment.
The specific embodiment
Further illustrate the utility model below in conjunction with embodiment and accompanying drawing.
Referring to Fig. 1
The Thin-walled Aluminum matter inner bore of part turning clamp that the utility model provides, it has a fixed cover 2 and a clamping fixture seat 1, there is cavity 2b in fixed cover 2, the front end of fixed cover 2 and rear end have through hole 2d and the screwed hole 2a communicated with its cavity 2b, clamping fixture seat is connected as a single entity and forms with the afterbody 1a that is Rotary-table by being cylindrical head 1b, the tapering of the afterbody 1a of this Rotary-table is identical with the tapering of lathe main axis hole, the head of clamping fixture seat 1 has external screw thread 1c, screwed hole 2a on fixed cover 2 connects with the external screw thread 1c of clamping fixture seat 1 head, the head of clamping fixture seat 1 has ladder blind hole 1d, the macropore of this ladder blind hole 1d is truncated cone-shaped.The pinch tube 3 be mated is housed in the macropore of ladder blind hole 1d, has the open slot 3a more than two on the tube wall of pinch tube 3, a spring 4 is housed in ladder blind hole 1d.
The end face 2c that fixed cover 2 cavity 2b and through hole 2d are crossing and the front end face 3b of pinch tube 3 are taper seat, and the tapering of two taper seats is identical.
Referring to Fig. 2
Have six open slot 3a on the tube wall of pinch tube 3, the trend of each open slot 3a be along pinch tube 3 axially, open slot 3a is circumferentially uniform along pinch tube 3.
As seen from Figure 1, workpiece 5 is packed in pinch tube 3, after pinch tube 3 is contained in the macropore of ladder blind hole 1d, by fixed cover 2 with in further screwing after clamping fixture seat 1 connects, the end face 2c of cavity 2b and pinch tube 3 front end face 3b against, pinch tube 3 is progressively entered in the macropore of ladder blind hole 1d, and then make pinch tube 3 progressively be out of shape workpiece 5 clampings; After the afterbody 1a that clamping fixture seat 1 rear portion is to Rotary-table packs in the spindle hole of lathe, can turning process the endoporus 5a of workpiece 5; After workpiece 5 machines, fixed cover 2 is separated with clamping fixture seat 1, workpiece 5 and pinch tube 3 can together be ejected by spring 4, can then to next workpiece, processing be installed.
