End surface arc turning clamp

Abstract

The invention provides an end surface arc turning clamp which belongs to the technical field of clamp manufacturing. The clamp comprises a clamp base, wherein the clamp base forms an annular structure, and the central line is vertical to the upper surface; a plurality of round pipe workpiece fixing seats are uniformly distributed on the upper surface of the clamp base, and each round pipe workpiece fixing seat is internally provided with a round through hole; the diameters of all round through holes are same, the central lines of the through holes are all parallel to the upper surface of the clamp base, have consistent height and intersect at the central line of the annular clamp base; the inner side surface of each round pipe workpiece fixing seat is a saddle-shaped surface having a concentric circle with the clamp base; and the radiuses from the centers of the clamp bases to the saddle-shaped surfaces of all the round pipe workpiece fixing seats are same. Compared with the prior art, the end surface arc turning clamp has the characteristics of reasonable design, simple structure, convenience of use, and the like and can broaden the processing range of a lathe when applied to an ordinary lathe and realize partial functions of a milling machine so as to improve the working efficiency and reduce the processing cost.

Description

(1) Technical field [0001] The invention relates to a fixture, in particular to an end surface arc turning fixture used on a common lathe to process the arc end surface of a round tube workpiece. (2) Background technology [0002] At present, the known lathe processing can only perform circular cutting processing on the workpiece, but cannot perform arc-shaped processing on the end surface of the workpiece. Therefore, it is necessary to use grinding wheel grinding when processing the saddle surface, which is not only time-consuming and laborious, but also has poor processing accuracy; although the accuracy of milling machine processing can meet the requirements, the efficiency is too low. (3) Contents of the invention [0003] The technical task of the present invention is to aim at the deficiencies of the prior art, and provide an end surface arc-shaped turning fixture capable of performing arc-shaped processing on the end surface of a workpiece. [0004] The technical s...

Problems solved by technology

[0002] At present, the known lathe processing can only perform circular cutting on the workpiece, and cannot process the arc of the end surface of the workpiece.

Therefore, it is necessary to use grinding wheel grinding when processing the saddle surface, which is not only time-consuming and laborious, but also has poor processing accuracy; although the accuracy of milling machine processing can meet the requirements, the efficiency is too low
