Turning clamp

Abstract

The invention discloses a turning clamp. The clamp comprises a clamp body, a taper pin guide sleeve, a taper pin, an elastic part, a fastening bolt and an anti-rotating block; the taper pin guide sleeve is arranged in a centre of the clamp body and protrudes out of the clamp body; the taper pin capable of sliding in the taper pin guide sleeve is arranged in the taper pin guide sleeve; the elastic part is arranged between the taper pin guide sleeve and the taper pin; when the elastic part is in an initial condition, an external end face of the taper pin exceeds an end face of the taper pin guide sleeve; and the clamp body is further provided with the fastening bolt and the anti-rotating block. When the turning clamp disclosed by the invention is not used, the elastic part is in the initial condition and the external end face of the taper pin exceeds the end face of the taper pin guide sleeve; when the work-piece to be processed is clamped on the clamp, the elastic part is compressed; the taper pin is pushed by a restoring action force of the elastic part, so that the taper pin is well contacted with the work-piece to be processed; the location error is well reduced and the processing precision is guaranteed; and the turning clamp is suitable for mass processing and production.

Description

technical field [0001] The invention relates to a fixture, in particular to a turning fixture used for processing bushing parts, and belongs to the technical field of workpiece clamping devices for mechanical processing. Background technique [0002] as attached figure 1 A bushing type part is shown that requires turning finishing on its surface. The existing processing method is generally to clamp the left and right ends of the workpiece separately, and then turn it. In the process of production and processing, the left taper hole is often used as the positioning surface of the workpiece, but because the surface of the workpiece is not smooth, It belongs to the rough surface, and its specific size is inconsistent, so that the positioning error is large during processing, resulting in the accuracy of the processed workpiece cannot be guaranteed, and it is not suitable for mass processing and production. Contents of the invention [0003] In view of the above-mentioned te...
