Abstract

A positioning plate with a three-pin positioning structure comprises a turnover beam and a positioning plate body. A connecting plate with a plurality of bolt holes is arranged at the bottom of the positioning plate body, a notch is formed in the top of the positioning plate body, the right side of the turnover beam is hinged to the positioning plate body through a supporting plate, the turnover beam is fixedly connected with the supporting plate, the left side of the turnover beam is connected with the center of an n-shaped base, and the n-shaped base is in butt joint with the notch of the positioning plate body. A first ejector pin fixing piece is arranged on the inner side of the notch, and an ejector pin which is upwards arranged is installed on the top of the first ejector pin fixing piece. A second ejector pin fixing piece is arranged on the outer side of the turnover beam, and two ejector pins which are downwards arranged are installed on the lower portion of the second ejector pin fixing piece. According to the positioning plate with the three-pin positioning structure, workpieces can be linearly positioned, the turnover beam drives the n-shaped base to be matched with the positioning plate body, the workpieces can be fixed, and therefore positioning accuracy and stability are guaranteed.

Description

technical field [0001] The invention relates to a positioning plate with a three-needle positioning structure, which belongs to the field of processing and positioning of mechanical accessories. Background technique [0002] There are many kinds of machining equipment at present, among which various auxiliary equipment are needed in the process of positioning, thimble is one of them, and thimble often plays the role of support. However, the thimble cannot be positioned directly during use, and must be positioned with the help of tools such as a positioning plate, so the structure of the positioning plate also determines the stability and accuracy of the positioning of the thimble. Contents of the invention [0003] The purpose of the present invention is to provide a positioning plate with a three-needle positioning structure to solve the problems of stability and precision of ejector pin positioning. [0004] The purpose of the present invention is specifically achieved ...
