Abstract

The invention relates to a machine tool turning deformation prevention clamp, in particular to a turning deformation prevention clamp for annular thin-wall parts. The turning deformation prevention clamp comprises an annular body, wherein an outer circumference surface matched with an inner hole of a processed part is arranged on the body, the body is divided into a plurality of mutually separated fan-shaped parts by a plurality of radial cutting grooves, and a connecting hole capable of being connected with one clamping jaw of a lathe chuck is formed in each fan-shaped part. When an annular thin-wall hollow pipe is turned, each part of the body is respectively assembled with each clamping jaw of the lathe chuck, and the outer circumference surface on the body is used for supporting the inner circumference surface of the processed part so that the clamping force of each part of the processed part is uniformly distributed, so the deformation of the processed part is reduced, and the processing quality of a workpiece is improved. A plurality of outer circumference surfaces with the gradually enlarged diameters stage by stage is arranged on the body, the turning deformation prevention clamp can adapt to the processing of the processed parts with different dimensions, and the application range is enlarged.

Description

Ring-type thin-wall part Vehicle Processing anti-deformation fixture

Technical field

The present invention relates to a kind of Vehicle Processing anti-deformation fixture of lathe Vehicle Processing anti-deformation fixture, particularly a kind of ring-type thin-wall part.

Background technology

Existing machined often will be processed the ring-type thin-wall hollow pipe, because its wall thickness is thinner in producing, while adopting scroll chuck on conventional lathe or chuck to clamp, because the point of application of the chucking power of chuck is inhomogeneous, easily cause distortion when clamping, this has reduced the crudy of workpiece.Therefore, need a kind of fixture to reduce the distortion of workpiece when being clamped by chuck, improve crudy.

Summary of the invention

Technical problem to be solved by this invention is, a kind of distortion can reduce the ring-type thin-wall part and clamped by chuck the time is provided, and improves the fixture of Vehicle Processing quality.

Technical scheme of the present invention is:

A kind of ring-type thin-wall part Vehicle Processing anti-deformation fixture, it comprises the body of a ring-type, is provided with the outer circumference surface matched with the endoporus of work piece on body; By several, the groove that cuts off radially is divided into a plurality of fan-shaped part be separated from each other to body, on each fan-shaped part, be provided with can with a connecting hole that claw is connected of machine chuck.

The described groove that cuts off can be provided with three, and it is divided into three fan-shaped parts to body.

The described groove that cuts off can arrange four, and it is divided into four fan-shaped parts to body.

On described body, there are a plurality of diameters to become step by step large outer circumference surface.

Advantage of the present invention is: when car ring-type thin-wall hollow pipe, the various piece of body is assembled together with each claw of lathe chuck respectively, with on body outer circumference surface support the inner peripheral surface of work piece, the clamping force of work piece each several part is uniformly distributed, thereby reduced the distortion of work piece, improved the crudy of workpiece.Be provided with a plurality of diameters and become step by step large outer circumference surface on body, can adapt to the processing of the work piece of different size, the range of application enlarged.

The accompanying drawing explanation

Fig. 1 is end face structure schematic diagram of the present invention;

Fig. 2 is the cutaway view of Fig. 1 in the A-A direction.

The specific embodiment

As shown in the figure, a kind of ring-type thin-wall part Vehicle Processing anti-deformation fixture, it is characterized in that: it comprises the body 1 of a ring-type, is provided with the outer circumference surface 4 matched with the endoporus of work piece 6 on body 1; By several, the groove 2 that cuts off radially is divided into a plurality of fan-shaped part be separated from each other to body 1, is provided with the connecting hole 3 that can be connected with a claw of machine chuck on each fan-shaped part.

The described groove 2 that cuts off can be provided with three, and it is divided into three fan-shaped parts to body, and described three fan-shaped parts coordinate with three claws of scroll chuck of lathe respectively.

The described groove 2 that cuts off can be provided with four, and it is divided into four fan-shaped parts to body, and described four fan-shaped parts coordinate with four claws of the chuck of lathe respectively.

On described body 1, there are a plurality of diameters to become step by step large outer circumference surface 4.

Screw 7 is fixedly connected on body 1 on chuck 5 through connecting hole 3, and outer circumference surface 4, along with chuck 5 moves, finally supports the inner peripheral surface of measured workpiece 6.
