Description

Technical Field

[0001] The present invention relates to primer performance testing equipment, in particular to a front body of a multiple-shot primer ignition performance testing instrument. Background Art

[0002] Our army started the primer ignition performance test as early as forty years ago. At present, our army has been using the simple test equipment uniformly distributed in the 1970s and 1980s in its ammunition testing experiments.

[0003] The existing primer test equipment has a small working range and can only be used to complete the ignition performance test of some screw-in primers. It has low technical performance and clumsy and backward methods. Especially during the entire test process, there is a lot of noise and smoke, and there are many unsafe factors, which cause physical and mental harm to the experimenters. For example, the existing primer test equipment can only load one primer at a time for testing, and the primer needs to be replaced after each primer is fired. Replacing the primer requires cumbersome operations, resulting in low work efficiency, which ultimately affects the overall test efficiency.

[0004] How to reduce the damage to operators during the test, improve test efficiency, improve test methods, and increase the accuracy of test results are issues that need to be urgently addressed by existing primer test equipment. Summary of the invention

[0005] The purpose of the present invention is to provide a front body of a multiple-shot primer ignition property tester, so as to solve the problems that the primer test device is heavy to use, cumbersome to operate, difficult to install, and can only load one primer at a time for testing, so as to realize the multiple-shot primer ignition property test.

[0006] In order to solve the above problems, the present invention discloses a front body of a multiple-fire primer ignition property tester, which includes a front body body, a primer clamp push rod, a slide seat and a multiple-fire primer delivery clamp.

When the primer clamp push rod slides forward, the pawl pushes the multi-shot primer delivery clamp forward in the pawl groove, and the spring I lifts the pawl to prevent the pawl from falling out of the pawl groove, so that the multi-shot primer delivery clamp moves forward. After the multi-shot primer delivery clamp moves into place, the primer clamp push rod slides backward, and the pawl compresses the spring I to make the pawl fall out of the pawl groove. As the primer clamp push rod moves backward, the pawl is again stuck in another pawl groove. When the primer clamp push rod is pushed forward again, the multi-shot primer delivery clamp will continue to move forward. The multi-shot primer delivery clamp is equipped with multiple primers, multiple primers are linearly arrayed, and the number of multiple pawl grooves is the same as the number of multiple primers. Repeating the above process can realize the forward delivery of the multi-shot primer delivery clamp, and then cooperate with the firing device to realize the firing of the primer. It avoids the need to reinstall the primer after each firing, improves work efficiency, saves time, and reduces the work intensity of the operator.

When the primer delivery clamp slides backward, the release pull block is pulled down to compress the spring II, and the top head leaves the bottom surface of the multi-shot primer delivery clamp. Furthermore, a plurality of positioning holes can be set on the bottom surface of the multi-shot primer delivery clamp, so that each time the multi-shot primer delivery clamp is delivered into place, the top head is inserted into a positioning hole to achieve positioning.
