Abstract

The invention provides a workpiece positioning device, and belongs to the technical field of positioning clamps. According to the workpiece positioning device, the problem that during current clampingof a workpiece, the positioning efficiency is low is solved. The positioning device comprises a cylindrical internal expansion clamp, a clamping part capable of being pushed out is arranged on the outer side wall of the internal expansion clamp, the positioning device comprises a shell with an inner hole and a positioning piece arranged in the shell, an elastic piece is further arranged in the shell, the positioning piece can stretch out from the front end of the shell under the elastic force effect of the elastic piece and get close to the internal expansion clamp, the inner wall of the shell can guide horizontal moving of the positioning piece, and the tip of the front end of the positioning piece is provided with a positioning face abutting against the workpiece. The positioning devicehas the advantage of improving the positioning efficiency greatly.

Description

technical field [0001] The invention belongs to the technical field of positioning fixtures, and relates to a positioning device, in particular to a workpiece positioning device. Background technique [0002] When using a lathe to cut workpieces, it is often encountered a class of blank workpieces with multiple blank surfaces such as two sides, four sides, and six sides, and each blank surface needs to be cut to meet production and processing requirements. Usually, the cutting process of this kind of workpiece is to set it on the fixture, the fixture is tensioned, and then the surface to be processed is accurately positioned, and then the positioned surface is cut by the tool, and the workpiece is replaced after processing. It needs to be repositioned every time. The difficulty in processing lies in how to quickly and accurately locate the workpiece so that it meets our processing requirements. [0003] The common method of workpiece positioning is to measure the offset dis...
