Description

Technical Field

[0001] This utility model relates to the field of artillery firing pin measurement technology, specifically a simple artillery firing pin protrusion measurement device. Background Technology

[0002] Artillery requires regular inspection and maintenance after use, and measuring the firing pin protrusion is a crucial aspect of this process. Firing pin protrusion refers to the amount by which the firing pin tip extends beyond the front plane of the bolt. This parameter is essential for artillery design and maintenance. Traditional measurement methods suffer from operational difficulties, low accuracy, and are not suitable for rapid measurement. Therefore, a simplified device for measuring artillery firing pin protrusion is proposed. Utility Model Content

[0003] The technical problem to be solved by this utility model is to provide a simple artillery firing pin protrusion measuring device to address the above-mentioned shortcomings.

[0004] To solve the above technical problems, the present invention adopts the following technical solution:

[0005] A simple device for measuring the protrusion of a firing pin in artillery includes a measuring plate, a strong magnetic base, a connecting seat, a movable infrared rangefinder, and a fixed infrared rangefinder. The strong magnetic base is used to adhere to the firing surface of the breechblock. A connecting seat is horizontally arranged on the top of the strong magnetic base, and a measuring plate parallel to the firing surface is horizontally arranged on the top of the connecting seat. A groove is formed on the front of the measuring plate, and a threaded rod is horizontally arranged in the groove. The rear end of the threaded rod passes through the measuring plate and is parallel to the measuring plate. A slider is threadedly connected to the middle of the threaded rod. A knob is located at the rear end of the threaded rod outside the measuring plate. Rotating the knob can drive the threaded rod. The rod rotates, which in turn drives the slider to move horizontally. A movable infrared rangefinder is installed on the slider. The movable infrared rangefinder is facing the firing surface of the breechblock and is used to measure the distance L1 between itself and the firing surface of the breechblock. A fixed infrared rangefinder is installed on the measuring plate. The fixed infrared rangefinder is fixed to the front end of the measuring plate. When the strong magnetic seat is attracted to the firing surface of the breechblock, the fixed infrared rangefinder is located directly opposite the firing pin. The fixed infrared sensor is used to measure the distance L2 between itself and the tip surface of the firing pin. The firing surfaces of the movable infrared rangefinder and the fixed infrared rangefinder are flush.

[0006] Furthermore, the strong magnetic base includes an electromagnet, a battery, and a gear switch. The gear switch is electrically connected to both the electromagnet and the battery, and is used to adjust the magnetic strength of the electromagnet.

[0007] Furthermore, the gear switch is equipped with a weak magnetic gear and a strong magnetic gear.

[0008] Furthermore, the measuring board is equipped with two switches for respectively starting and stopping the active infrared ranging sensor and the fixed infrared ranging sensor. The active infrared ranging sensor and the fixed infrared ranging sensor are electrically connected to the two switches via wires, and both switches are electrically connected to an external display device via wires.

[0009] Compared with the prior art, the present invention, by adopting the above technical solution, has the following advantages:

[0010] This invention uses a strong magnetic base to adhere to the firing surface of the breechblock, quickly completing the initial positioning and installation of the device. The position of the movable infrared rangefinder sensor can be easily adjusted using a threaded rod and a knob. The overall operation process is simple and reduces the difficulty of operation.

[0011] By employing both active and fixed infrared rangefinders, and utilizing the fact that their emitting surfaces are flush and they measure the distances to the firing surface and firing pin respectively, combined with an electrically connected external display device, data can be acquired more accurately, thus improving detection precision.

[0022] like Figure 1-5 As shown, a simple artillery firing pin protrusion measuring device includes a measuring plate 1, a strong magnetic base 2, a connecting seat 3, a movable infrared rangefinder 4, and a fixed infrared rangefinder 5. The strong magnetic base 2 is used to adhere to the firing surface of the breechblock. The connecting seat 3 is horizontally arranged on the top of the strong magnetic base 2. The measuring plate 1, parallel to the firing surface, is horizontally arranged on the top of the connecting seat 3. A groove 6 is formed on the front of the measuring plate. A threaded rod 7 is horizontally arranged in the groove 6. The rear end of the threaded rod 7 passes through the measuring plate 1 and is parallel to the measuring plate 1. A slider 8 is threadedly connected to the middle of the threaded rod 7. A knob 10 is arranged at the rear end of the threaded rod 7 outside the measuring plate 1. By rotating the knob... 10 can drive the threaded rod 7 to rotate, thereby driving the slider 8 to translate. The slider 8 is equipped with a movable infrared range sensor 4. The movable infrared range sensor 4 is facing the firing surface of the breechblock and is used to measure the distance L1 between itself and the firing surface of the breechblock. The measuring plate 1 is equipped with a fixed infrared range sensor 5. The fixed infrared range sensor 5 is fixed at the front end of the measuring plate 1. When the strong magnetic seat 2 is attracted to the firing surface of the breechblock, the fixed infrared range sensor 5 is located directly opposite the firing pin. The fixed infrared sensor is used to measure the distance L2 between itself and the tip surface of the firing pin. The firing surfaces of the movable infrared range sensor 4 and the fixed infrared range sensor 5 are flush.

[0023] In one embodiment, the strong magnetic base 2 includes an electromagnet, a battery, and a gear switch 9. The gear switch 9 is electrically connected to both the electromagnet and the battery, and is used to adjust the magnetic strength of the electromagnet.

[0024] In one implementation, the gear switch 9 is provided with a weak magnetic gear and a strong magnetic gear.

[0025] In one embodiment, the measuring plate 1 is provided with two switches for respectively starting and stopping the active infrared ranging sensor 4 and the fixed infrared ranging sensor 5. The active infrared ranging sensor 4 and the fixed infrared ranging sensor 5 are electrically connected to the two switches via wires, and both switches are electrically connected to an external display device via wires.

[0026] The working process of this utility model is as follows: Turn the gear switch 9 to the weak magnetic position, place the strong magnetic base 2 on the firing surface of the breechblock, and the strong magnetic base 2 is attracted to the firing surface of the breechblock. Then, turn on the fixed infrared rangefinder 5 by switching on the switch. Move the strong magnetic base 2 by observing the infrared light illumination point of the fixed infrared rangefinder 5 so that the infrared light illumination point of the fixed infrared rangefinder 5 is located on the tip surface of the firing pin. Then, turn the gear switch 9 to the strong magnetic position so that the strong magnetic base 2 is firmly fixed on the breechblock. Then, turn on the movable infrared rangefinder 4 to measure. The fixed infrared rangefinder 5 and the movable infrared rangefinder 4 transmit the measurements L1 and L2 to the external display device. After the external display device processes and displays L1 and L2, the firing pin protrusion amount is obtained by subtracting L1 from L2.

[0027] After the initial test, the position of the movable infrared ranging sensor 4 is changed by knob 10 and screw, and then the measurement is performed again. After three measurements, the average value of the striker protrusion obtained from the three measurements is taken as the final result.
