Multilateral structure

Abstract

The invention provides a multilateral structure, which comprises a plurality of acute angles, a plurality of obtuse angels, six convex angles and four concave angles, wherein the convex angles are connected with external concave holes; and the concave angles are connected with external bosses. The multilateral structure provided by the invention has the advantages that a connected mechanism can be prevented from rotating, and stability of the device can be effectively enhanced.

Description

technical field [0001] The invention relates to a motor, in particular to a polygonal structure. Background technique [0002] Gauge is a special inspection equipment used to measure and evaluate the dimensional quality of parts. At the parts production site, the on-line detection of parts is realized through the inspection tool. For this reason, the parts need to be accurately installed on the inspection tool, and then the surface and periphery of the part should be inspected by visual inspection, measuring table, or caliper. It is also possible to visually inspect the holes of different properties on the parts and the connection positions between parts with the help of inspection pins or visual inspection, so as to ensure the rapid judgment of the quality status of parts during production. For small parts, positioning pins are generally inserted into the pin sleeves to fix the parts, but because the pin sleeves and positioning pins are in cylindrical contact, the parts ar...

Problems solved by technology

For small parts, positioning pins are generally used to insert into the pin sleeves to fix the parts, but because the pin sleeves and positioning pins are in cylindrical contact, the parts are unstable and prone to rotation, which affects the test results
