Embodiment Construction

[0014] The present invention is described below in conjunction with accompanying drawing.

[0015] as attached image 3 A kind of fixture for arc-cone turning of the present invention shown, comprises three-jaw chuck 1 and machine tool tip 2, is provided with fixed sleeve 3 in comprising described three-jaw chuck 1; Said fixed sleeve The inner hole 4 of 3 is tapered; the section of the fixed sleeve 3 is "T"-shaped; the "-" of the "T"-shaped fixed sleeve 4 is in close contact with the three-jaw chuck 1.

[0016] as attached Figure 4 As shown in the present invention, a fixture for turning an arc-shaped conical part is used. When in use, the arc-shaped conical part 14 to be processed is inserted into the fixed sleeve 3, and then the center of the machine tool 2 is used to withstand the circular arc-shaped part to be processed. The head of the arc cone 14 realizes clamping. The fixture for turning arc-shaped conical parts of the present invention utilizes the frictional force...

Abstract

The invention discloses a clamp for turning a circular arc conical part. The clamp comprises a three-jaw chuck and a machine tool center, wherein a fixing sleeve is arranged in the three-jaw chuck; an inner hole of the fixing sleeve is conical; a section of the fixing sleeve is of a T shape; and a linear part of the T-shaped fixing sleeve is abutted against the three-jaw chuck. According to the clamp for turning the circular arc conical part, which is disclosed by the invention, the power is transmitted by using a friction force between a conical inner hole surface in the fixing sleeve and an excircle surface of the circular arc conical part to be processed and automatic centering is realized, so that the circular arc conical part is convenient to mount and dismount and the processing efficiency is increased; and in addition, the defect that the traditional circular arc conical part for the clamp cannot be detached is overcome and the service effect is greatly improved.

Description

technical field [0001] The invention relates to a fixture, in particular to a fixture for turning an arc-shaped conical part on a lathe, and belongs to the technical field of workpiece clamping devices for mechanical processing. Background technique [0002] Among the many types of mechanical parts, there is a kind of arc-shaped conical part. Due to its special structure, when it is turned on a lathe, if it is directly clamped with a three-jaw chuck, the clamping will be unstable. There are difficulties in turning arc-conical parts. So someone designed a fixture, such as attached figure 1 As shown, it includes a three-jaw chuck 11 , a small thread mandrel 12 and a machine tool tip 13 , and the small thread mandrel 12 is arranged in the three-jaw chuck 11 . When turning the arc-shaped conical parts, if the attached figure 2 As shown, the head of the small threaded mandrel 12 is screwed into the positioning screw hole 15 provided at the tail of the arc-shaped cone 14, and...
