A fixture device for enameled wire paint film tensile test

Abstract

The invention discloses a jig device for enameled wire paint film tensile test, which comprises: a bracket, an accommodating space open on one side is arranged in the bracket; The fixing part at one end of the fixed test sample; the positioning pin, the positioning pin passes through the bracket at one end of the accommodating space, and abuts against the side wall of the rotating shaft, and is used to limit the axial displacement of the rotating shaft and the rotating shaft The rotation of the fixed shaft, the fixed shaft passes through the bracket and the rotating shaft at the other end of the accommodating space, and is used to limit the axial displacement of the rotating shaft and the rotation of the rotating shaft; the eccentric screw, the eccentric screw extends into the rotating shaft away from The end of one end of the fixed shaft is fixedly connected with the rotating shaft, and is used for fastening one end of the test sample. The invention guarantees that the paint film of the test piece is complete and is not damaged by the fixture, and has stable clamping force and no slippage, thereby ensuring the accuracy of test results.

Description

An enameled wire paint film tensile test fixture device technical field The present invention relates to the technical field of material mechanics test device, relate in particular to a kind of enameled wire paint film tensile test clip device. Background technique [0002] With the rapid development of my country's automobile industry, my country has become the main market for new energy vehicles. new energy vehicles Enamelled copper flat wire for drive motor has been used in motors of major new energy vehicle brands due to its excellent performance. [0003] The operation of new energy electric vehicles is different from general industrial applications, and the requirements for the drive system are relatively high. want The drive motor has high energy efficiency, energy saving and emission reduction; high torque at low speed, fast starting of the car, high power at high speed, high Good overtaking performance; speed regulation with high constant power. For the re...
