Abstract
Description
Technical Field
[0001] This utility model belongs to the field of detection equipment technology, specifically relating to a device for detecting the depth of the propellant surface on a projectile. Background Technology
[0002] In the military projectile assembly process, the quasi-addition of explosives to the projectile is crucial to its technical and tactical performance. Considering the convenience of weighing after adding explosives and improving the overall production line cycle time, improvements are needed in the use of explosion-proof electronic scales and other methods.
[0003] Currently, the most common detection method is the laser rangefinder. However, this method has a problem: when the propellant surface is not flat, the detection results will be inaccurate. Moreover, since this location is close to the anti-riot workshop, if a secondary explosion occurs in the workshop, it will endanger personal safety and equipment safety. For the sake of personnel safety, it is necessary to adopt an automated method to detect the propellant surface depth. Utility Model Content
[0004] In view of the problems mentioned above in the background art, the purpose of this utility model is to provide a device for detecting the depth of the propellant surface on a projectile.
[0005] To achieve the above-mentioned technical objectives, the technical solution adopted by this utility model is as follows:
[0006] A device for detecting the depth of a projectile propellant surface includes a frame, a mounting plate mounted on the frame, a motor mounted on the mounting plate, a lead screw connected to the output end of the motor, slide rails mounted on both sides of the lead screw on the frame, a movable plate mounted on both slide rails, a threaded sleeve fixedly mounted on the back side of the movable plate, the threaded sleeve being threadedly connected to the lead screw, a bracket connected to the lower end of the movable plate, a guide sleeve mounted on the bracket, and a reference plate mounted on the lower side of the guide sleeve.
[0007] The movable plate is equipped with a displacement sensor. The output end of the displacement sensor is connected to a pull rod. The end of the pull rod is connected to a connecting sleeve. The connecting sleeve is connected to a guide rod. The guide rod slides and matches the guide sleeve. The lower end of the guide rod is connected to a detection probe.
[0008] Furthermore, the mounting plate has a photosensitive film mounted next to the slide rail, and the moving plate has a transmitter mounted on it. The signal input terminal of the transmitter corresponds to the photosensitive film. This design allows for control of the moving position of the moving plate.
[0009] Furthermore, the mounting plate is equipped with a cable chain on the side of the slide rail. This design allows the cable chain to protect and guide the cables, ensuring that they operate stably and safely during equipment movement without causing interference.
[0010] Furthermore, the movable plate is equipped with a guide rail, the guide rail is equipped with a slider, and the displacement sensor is installed on the slider. This design allows for adjustment of the position of the movable plate, thereby adapting to normal use under different needs and expanding its applicability.
[0011] Furthermore, the motor output end is connected to a coupling. This design allows the motor to withstand various external forces during operation, such as impacts and vibrations. The coupling's elasticity and flexibility effectively absorb and buffer these forces, reducing damage to the motor. Simultaneously, the coupling also reduces vibration and noise generated during motor operation, improving the smoothness and stability of motor operation.
[0012] The beneficial effects of using this utility model are as follows:
[0013] The structural design of this utility model, compared with the detection structure using laser ranging, adopts a physical contact method for measurement, which can effectively flatten the medicine surface during measurement and avoid problems such as fluffiness, thus ensuring the accuracy of the detection data;
[0014] This invention is a fully automated method for detecting the depth of medicine application, so it is unlikely to affect personal safety and thus ensures safety. Attached Figure Description

Detailed Implementation
[0021] To enable those skilled in the art to better understand this utility model, the technical solution of this utility model will be further described below in conjunction with the accompanying drawings and embodiments.
[0022] like Figure 1 , Figure 2 , Figure 3 As shown, the present invention discloses a device for detecting the depth of a projectile propellant surface, comprising a frame 1, a mounting plate 2 mounted on the frame 1, a motor 3 mounted on the mounting plate 2, a lead screw 4 connected to the output end of the motor 3, slide rails 5 mounted on both sides of the lead screw 4 on the frame 1, a movable plate 6 mounted on both slide rails 5, a threaded sleeve 7 fixedly mounted on the back side of the movable plate 6, the threaded sleeve 7 being threadedly connected to the lead screw 4, a bracket 8 connected to the lower end of the movable plate 6, a guide sleeve 9 mounted on the bracket 8, and a reference plate 10 mounted on the lower side of the guide sleeve 9.
[0023] The movable plate 6 is equipped with a displacement sensor 11. The output end of the displacement sensor 11 is connected to a pull rod 12. The end of the pull rod 12 is connected to a connecting sleeve 13. The connecting sleeve 13 is connected to a guide rod 14. The guide rod 14 slides and matches the guide sleeve 9. The lower end of the guide rod 14 is connected to a detection probe 15.
[0024] In this implementation example, when using a device for detecting the propellant surface depth of a projectile, after the projectile is loaded with propellant, it leaves the anti-riot chamber via a sliding table fixture. The propellant surface depth is detected at the exit of the anti-riot chamber; this is the pre-automation equipment of this structure. When the projectile moves to the lower side of the detection probe 15, the motor 3 runs, driving the lead screw 4 to rotate. The rotation of the lead screw 4, in conjunction with the threaded sleeve 7, causes the moving plate 6 to move up and down under the limit of the slide rail 5. The moving plate 6 moves downwards until the reference plate 10 contacts the surface of the projectile's ammunition loading port. When the moving plate 6 moves downward, the detection probe 15 also comes into contact with the propellant surface inside the projectile. When the projectile comes into contact with the reference plate 10, the detection probe 15, which is in contact with the propellant surface, pushes the pull rod 12 upward under the reaction force. The pull rod 12 then pushes the detection end of the displacement sensor 11 to move. This displacement data is the depth data of the propellant surface. When this data is less than the set calibration value of the displacement sensor 11, it indicates that the propellant surface is too deep. Conversely, it indicates that the propellant surface is too shallow. This achieves the purpose of detecting the depth of the propellant surface.
[0025] Preferably, a photosensitive film 16 is mounted on the mounting plate 2 next to the slide rail 5, and a transmitter 17 is mounted on the moving plate 6. The signal input terminal of the transmitter 17 corresponds to the photosensitive film 16. This design can control the moving position of the moving plate 6. In fact, a displacement detection and control structure can also be considered depending on the specific situation.
[0026] Preferably, a cable chain 18 is installed on the side of the slide rail 5 on the mounting plate 2. This design allows the cable chain to protect and guide the cables, ensuring that the cables can operate stably and safely when the equipment is in motion, without causing interference. In fact, the structure of the cable bundle can also be considered depending on the specific situation.
[0027] Preferably, the movable plate 6 is equipped with a guide rail 19, and the guide rail 19 is equipped with a slider 20. The displacement sensor 11 is installed on the slider 20. This design can adjust the position of the movable plate 6, thereby adapting to normal use under different needs and expanding the applicability. In fact, the position adjustment structure of the movable plate 6 can also be considered according to specific circumstances.
[0028] Preferably, the output end of the motor 3 is connected to a coupling 21. With this design, the motor 3 may be affected by various external forces during operation, such as impact and vibration. The coupling 21 has a certain degree of elasticity and flexibility, which can effectively absorb and buffer these external forces and reduce damage to the motor 3. At the same time, the coupling 21 can also reduce the vibration and noise generated during motor operation and improve the smoothness and stability of motor operation. In fact, the selection of coupling 21 can also be considered according to specific circumstances.
[0029] The above embodiments are merely illustrative of the principles and effects of this utility model and are not intended to limit the scope of this utility model. Any person skilled in the art can modify or alter the above embodiments without departing from the spirit and scope of this utility model. Therefore, all equivalent modifications or alterations made by those skilled in the art without departing from the spirit and technical concept disclosed in this utility model should still be covered by the claims of this utility model.
