AI Technical Summary
Existing technologies suffer from problems such as low utilization rate of device recovery tests and inability to effectively simulate the device's operating state during launch. These limitations prevent the effective simulation of the device's operating state, resulting in high testing costs and low efficiency.
A multi-assembly tooling for recovery tests was designed, comprising a disarming device, a shell cover, a shell, a test base, a set screw, and an anti-rotation bar. The combination of the anti-rotation bar and the drag cap enables the accurate assembly of multiple missiles and the simulation of launch states of the disarming device.
It has enabled efficient recovery tests of multiple anti-disarming devices, reduced test costs, improved test utilization, and can simulate the working conditions of various types of anti-disarming devices.

[0002] The recycling test of the present stage safety and arming device exists low utilization rate, cannot simulate the working state of the safety and arming device when launching well and the like.One bullet multi-loading tool can test multiple safety and arming devices in one recycling test, reduces the test cost and personnel operation steps, improves the recycling utilization rate of test, and can be suitable for multiple models of safety and arming devices. UTILITARY MODEL CONTENT
[0003] (I) technical problem to be solved
[0004] The utility model to be solved technical problem is: provide a one bullet multi-loading tool for recycling test for solving the general problem of typical safety and arming device in recycling test.
[0005] (II) technical scheme
[0006] In order to solve the above technical problem, the utility model provides a one bullet multi-loading tool for recycling test, safety and arming device 1, shell cover 2, shell body 3, test seat body 4, set screw 5, rotation stop strip 6;
[0007] The test seat body 4 is provided as a cylindrical structure, a plurality of shell bodies 3 are arranged in the test seat body 4 along the axial direction, recesses are formed in the bottom of each shell body 3, and a shell cover 2 is arranged above each shell body 3;
[0008] The rotation stop strip 6 is arranged between the inner side wall of the test seat body 4 and the shell body 3, a plurality of threaded holes are formed in the inner side wall of the test seat body 4, and the set screw 5 is screwed through the threaded hole in the test seat body 4 to tighten the rotation stop strip 6;
[0009] The positioning pin at the bottom of the safety and arming device 1 is aligned with the recess in the shell body 3, and the safety and arming device 1 is screwed tightly after being loaded into the shell body 3 through the shell cover 2;
[0010] The assembled plurality of shell bodies 3 are loaded into the test seat body along the rotation stop strip 6 and connected with the test sand bullet.
[0011] The recess at the bottom of the shell body 3 and the rotation stop strip 6 are arranged in the test seat body 4 through key-slot cooperation.
[0012] When the projectile is flying, the projectile body rotates in the air, the bottom of the test seat body 4 is provided with a resistance cap, the resistance cap generates a certain resistance, so that the projectile slows down and the overall range is shortened.
[0013] The rotation stop strip 6 prevents the shell body 3 from moving, and the resistance cap is used to prevent the projectile from being inserted into the target too deeply when the safety and arming device in the shell body 3 is disarmed.
[0014] (III) Beneficial Effects
[0015] Compared with the prior art, the utility model has the beneficial effects that solve the problem that the rotation in the test tool during the launching process of the safety and release device does not meet the actual working state, and the rotation stopping strip has two advantages: on the one hand, the rotation of the safety and release device is stopped; on the other hand, as a guide, the shell body with the groove is assembled conveniently. BRIEF DESCRIPTION OF DRAWINGS
[0016] Figure 1 It is a structural schematic diagram of the utility model. DETAILED DESCRIPTION
[0017] In order to make the purpose, content and advantages of the utility model more clear, the specific implementation of the utility model is described in further detail below in combination with the drawings and examples.
[0018] The embodiment provides a one-bullet multi-assembly tool for recovery test, a safety and release device 1, a shell cover 2, a shell body 3, a test seat body 4, a set screw 5 and a rotation stopping strip 6.
[0019] The test seat body 4 is provided as a cylindrical structure, a plurality of shell bodies 3 are arranged in the test seat body 4 along the axial direction, grooves are formed in the bottom of each shell body 3, and a shell cover 2 is arranged above each shell body 3.
