Example Embodiment

[0047] The present invention also has the following embodiments on the basis of the above:

[0048] In further embodiments of the present invention, please continue to refer to Figure 1 to Figure 10 As shown, the end of one end of the rotating shaft 4 is provided with an eccentric hole 41. The central axis of the eccentric hole 41 and the central axis of the rotating shaft 4 are parallel to each other and do not coincide with each other. The eccentric hole 41 includes a threaded hole and an optical hole that communicate with each other. A shaft 81 is threadedly connected with the threaded hole, and the second shaft 82 extends into the light hole.

[0049] In a further embodiment of the present invention, the peripheral wall of one end of the rotating shaft 4 is provided with a positioning groove 42 , the positioning groove 42 is located in the other side plate 22 , and the positioning pin 7 passes through the other side plate 22 and extends into the positioning groove 42, an...

Abstract

The invention discloses an enameled wire paint film tensile test clamp device, comprising a holder, wherein a storage space of which one side is open is set in the holder; a rotation shaft which penetrates the holder located at two ends of the storage space, wherein a fixing part for fixing one end of a test sample is set on the rotation shaft; a positioning pin which penetrates the holder locatedat one end of the storage space, resists against with a side wall of the rotation shaft and is used for limiting displacement in an axial direction of the rotation shaft and rotation of the rotationshaft; a fixing shaft which penetrates the holder located at the other end of the storage space and the rotation shaft and is used for limiting the displacement in the axial direction of the rotationshaft and the rotation of the rotation shaft; and an eccentric screw which stretches into an end part of an end of the rotation shaft away from the fixing shaft, is fixedly connected with the rotationshaft and is used for fastening one end of the test sample. According to the device, completeness of paint film of the test sample is ensured, under the condition that the paint film is not broken bya clamp, clamping force is stable without slipping, and accuracy of a test result is ensured.

Description

technical field [0001] The invention relates to the technical field of material mechanics test devices, in particular to a jig device for tensile test of enameled wire paint film. Background technique [0002] With the rapid development of my country's automobile industry, my country has become the main market for new energy vehicles. The enamelled copper flat wire for drive motors of new energy vehicles has been used in the 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 has relatively high requirements on the drive system. It is required that the drive motor has high energy efficiency, energy saving and emission reduction; high torque at low speed, fast start of the car, high power at high speed, good overtaking performance at high speed; speed regulation with high constant power. [0004] In response to the requirements of the above-m...
