Description

Technical Field

[0001] This utility model relates to the field of combined response component technology, and in particular to a device for detecting pull-out force. Background Technology

[0002] The projectile, including the fuse, is the part of the shell that directly completes the combat mission. It is also called the warhead of the shell. It consists of the fuse, the projectile body, the cartridge belt, the loading material, and the stabilization device (for projectiles that use tail fins for stabilization). Because a key bidding project of the company requires the testing of the projectile's pull-out force, a tooling for testing the pull-out force needs to be designed to meet the experimental requirements of the research and development stage. Moreover, most of the existing pull-out force testing devices are relatively complex to manufacture and inconvenient to disassemble. Utility Model Content

[0003] In view of this, the present invention provides a device for detecting the pull-out force, wherein the pull-out force tool 2 is connected to the projectile body by a thread, which makes the processing simple and disassembly convenient.

[0004] The technical solution is: a device for testing the force of a spring pull, including a spring pull tool 3, a cartridge, a projectile, a spring pull tool 2, and a spring pull tool 1. The spring puller is equipped with the spring pull tool 3 and the spring pull tool 1. The cartridge is rotatably connected to the spring pull tool 3. The end of the cartridge away from the spring pull tool 3 is clamped to the projectile. One side of the projectile is provided with a thread. The spring pull tool 2 is connected to the projectile through the thread. The spring pull tool 2 is fixedly connected to the spring pull tool 1.

[0005] The beneficial effects are: 1. This tooling is simple to process and easy to disassemble;

[0006] 2. The projectile body is connected to the spring-pulling tool 2 via a threaded connection. Attached Figure Description

[0010] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0011] Example 1: A device for detecting pull-out force, such as... Figure 1 and Figure 2As shown, it includes a spring-pulling tool 3, a cartridge case, a projectile body, a spring-pulling tool 2, and a spring-pulling tool 1. The spring-pulling tool 3 and the spring-pulling tool 1 are welded onto the spring-pulling tool 3. A cartridge case is rotatably connected to the spring-pulling tool 3. The end of the cartridge case away from the spring-pulling tool 3 is clamped to the projectile body. A thread is provided on one side of the projectile body. The spring-pulling tool 2 is connected to the projectile body through the thread. The spring-pulling tool 2 is fixedly connected to the spring-pulling tool 1.

[0012] The steps of this utility model are as follows: Step 1: Fix the spring-pulling force fixtures 1 and 3 on the spring-pulling machine;

[0013] Step 2: Connect the spring-pulling tool 2 to the spring body via threads;

[0014] Step 3: Secure the bottom of the cartridge case onto the spring-pulling fixture 3;

[0015] Step 4: Start the cartridge extractor and perform the cartridge extraction operation;

[0016] Step 5: After the projectile is pulled out, turn off the projectile extraction machine.

[0017] In this fixture, the projectile is connected to the spring-pulling tool 2 via a threaded connection, which simplifies the machining process and makes disassembly convenient.

[0018] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
