[0017] The use process of the sampling device for artillery shells and ammunition is as follows: 1. The centering and fixing process of the artillery shells: first, the warhead is taken out of the shell casing, and then the ammunition body is placed on the car plate of the trolley, and the car plate of the trolley and the ammunition body are moved together by rolling steel balls (the car plate of the trolley and the artillery shells do not slide relative to each other during the movement) until the ammunition body and the fixing ring are concentric, and then another semicircular ring body is clamped to the ammunition body, and the two semicircular ring bodies are fixed and tightened by bolts passing through the fixing holes on the fixing block. At this time, the ammunition body and the conical centering cylinder in the center of the car plate are concentric. Push the trolley onto the workbench, stop pushing when it hits the block on the workbench, open the centering cylinder, and use the push rod of the centering cylinder to push the centering cone through the centering hole on the workbench and move upward. After the centering cone contacts the inner wall of the cone-shaped centering cylinder in the center of the car plate, the trolley will move together with the ammunition body. After the car plate of the trolley hits the rollers upward, it can no longer move upward. The two rows of rollers perpendicular to each other on the upper and lower rolling bodies align the trolley with the centering cone to achieve the purpose of positioning and clamping.

[0018] 2. Adjustment of the drill bit position of the sampling device: When the centering and fixing action of the ammunition body is completed, the stepper motor of the lifting device is used to drive the screw to rotate. The screw and the thread inside the feed lifting body cooperate to drive the fixed connecting tube, hollow main shaft and drill bit of the sampling device to move downward quickly. When the drill bit is about to contact the upper part of the ammunition body, the stepper motor switches to the feed speed; when the cutting work is completed, the drill bit rises quickly.

[0019] 3. Operation process of sampling device and sampling device: When the stepper motor is switched to the feed speed, the motor is rotated through the control switch of the motor, and the exhaust fan connected to the outside of sampling tube A and sampling tube B is turned on at the same time. At this time, the motor drives the power input shaft and gear in the reducer to rotate through its power output shaft, and the gear is engaged with the transmission gear on the transmission shaft and drives the small gear to rotate. The small gear is engaged with the driven gear on the hollow main shaft and drives it to rotate, and finally drives the hollow main shaft to rotate. The hollow main shaft makes the hollow main shaft and the drill bit rotate at high speed through the bearing seat, while keeping the upper sampling tube A and sampling tube B of the bearing seat rotating; under the high-speed rotation of the drill bit, the drill bit drills the ammunition body to form ammunition debris. Since the sampling tube A and sampling tube B are connected to the hollow main shaft in an upper and lower structure, the strong negative pressure of sampling tube A and sampling tube B extracts the ammunition debris on the surface of the ammunition body. When the ammunition body sampling work is completed and the ammunition body is taken out from the trolley, the compression elastic force of the spring in the centering moving device is used to pull the centering moving device to reset; similarly, the limit spring in the limit device is used to pull the limit device to reset. The above process is the use process of this artillery ammunition sampling device.

[0052] The use process of the sampling device for artillery shells and ammunition is as follows: 1. The centering and fixing process of the artillery shells: first, the bullet is taken out from the shell casing, and then the ammunition body 14 is placed on the car plate 101 of the trolley 10, and the car plate 101 of the trolley 10 has two mutually perpendicular arc grooves 117, and the car plate 101 of the trolley 10 and the ammunition body 14 are moved together by rolling the steel ball 119 (during the movement, the car plate 101 of the trolley 10 and the artillery shells do not slide relative to each other), until the ammunition body 14 and the fixing ring 13 are concentric, and then another semicircular ring body 131 clamps the ammunition body 14, and the two semicircular ring bodies 131 are fixed and tightened by bolts passing through the fixing holes 133 on the fixing block 132, at which time the ammunition body 14 and the frustum-shaped centering cylinder 103 in the center of the car plate 101 are concentric.

[0053] Push the trolley 10 onto the workbench 1, stop pushing when it hits the block on the workbench 1, open the centering cylinder 7, and use the push rod of the centering cylinder 7 to push the centering cone 8 through the centering through hole 3 on the workbench and move upward. After the centering cone 8 contacts the inner wall of the cone-shaped centering cylinder 103 in the center of the vehicle plate 101, the trolley will move together with the ammunition body 14. After the vehicle plate 101 of the trolley 10 hits the roller 9037 upward, it can no longer move upward. The upper and lower rows of rollers 9037 perpendicular to each other on the upper rolling body 9033 and the lower rolling body 9034 align the trolley 10 with the centering cone 8 to achieve the purpose of positioning and clamping.

[0054] 2. Adjustment of the drill bit position of the sampling device: After the centering and fixing action of the ammunition body 14 is completed, the stepper motor 602 of the lifting device 6 is used to rotate, which drives the screw rod 604 to rotate. The screw rod 604 cooperates with the internal thread of the feed lifting body 607 to drive the fixed connection tube 406, the hollow main shaft 403 and the drill bit 407 of the sampling device 4 to move downward rapidly. When the drill bit 407 is about to contact the upper part of the ammunition body 14, the stepper motor 602 switches to the feed speed; when the cutting work is completed, the drill bit rises rapidly.

[0055] 3. Sampling device and sampling device operation process: When the stepper motor 602 is switched to the feeding speed, the motor 401 is rotated through the control switch of the motor 401, and the exhaust fan connected to the sampling tube A502 and the sampling tube B503 is turned on at the same time. At this time, the motor 401 drives the power input shaft 4022 and the gear 4023 in the reducer 402 to rotate through its power output shaft, and the gear 4023 is meshed with the transmission gear 4025 on the transmission shaft 4024, and drives the pinion 4026 to rotate, and the pinion 4026 is meshed with the driven gear 4027 on the hollow main shaft 403. The hollow main shaft 403 rotates at high speed through the bearing seat 404, and the upper sampling tube A502 and the sampling tube B503 of the bearing seat 404 rotate at the same time; under the high-speed rotation of the drill bit 407, the drill bit 407 drills the ammunition body 14 to form ammunition debris. Since the sampling tube A502 and the sampling tube B503 are connected to the hollow main shaft 403 in an upper and lower structure, the strong negative pressure of the sampling tube A502 and the sampling tube B503 extracts the ammunition debris on the surface of the ammunition body 14. When the ammunition body 14 is drilled, the ammunition body 14 is taken out from the trolley, and the compression elastic force of the spring 115 in the centering moving device 11 is used to pull the centering moving device 11 to reset; similarly, the limit spring 9039 in the limit device 9 is used to pull the limit device 9 to reset. The above process is exactly the use process of the sampling device of this artillery shell and ammunition.
