Cam-linkage thumbing mechanism of multi-shot primer ignition quality tester

Abstract

The invention relates to a primer ignition quality testing device, in particular to a cam-linkage thumbing mechanism of a multi-shot primer ignition quality tester. The cam-linkage thumbing mechanismcomprises a machine base, a linkage assembly, a rear machine body, a front machine body and a multi-shot primer conveying clamp. The multi-shot primer conveying clamp is slidingly connected to the front machine body. The rear machine body is arranged on one side of the front machine body. A primer clamping and pushing rod is slidingly connected with the side face of the front machine body. A pawlis connected into a pawl groove. The linkage assembly comprises a linkage rod and a driven rod. An eccentric connecting shaft is rotationally connected into a shaft hole I. A shaft hole II is connected to a top shaft. The top shaft is connected with a cam. The end, extending out of the rear machine body, of a thumbing element is connected to the outer contour of the cam. The multi-shot primer conveying clamp reciprocates through the linkage assembly and the rear machine body, so that multiple primers are conveyed forwards. The percussion of the multiple primers is realized through the thumbingelement and the cam. Use is stable, the structure is ingenious, work efficiency is improved, time is saved, and the working intensity of operators is relieved.

Description

technical field [0001] The invention relates to a primer ignition performance test device, in particular to a cam link toggle mechanism of a multi-sequence primer ignition performance tester. Background technique [0002] The ignition performance test of the primer was started by our army as early as 40 years ago. At present, the simple test equipment uniformly distributed in the 1970s and 1980s has been used in the ammunition testing experiments of our army. [0003] The existing primer experiment equipment has a small working range and can only be used to complete the ignition performance test of some screw-in primers. The technical performance is low, and the method is clumsy and backward. Too many, causing physical and mental harm to the experimenters. How to reduce the damage of the test to the operator, improve the test efficiency, improve the test method, and improve the accuracy of the test results are problems that need to be solved urgently for the existing primer...

AI Technical Summary

Problems solved by technology

[0004] The existing primer experiment of the prior art can only carry out the ignition performance test of one primer at a time, and the primer needs to be replaced every time the primer is fired, and the firing device needs to be adjusted accordingly after the primer is replaced, the operation is complicated and the work efficiency is low
