Description

Technical Field

[0001] This invention relates to the field of object arrangement technology, and in particular to an automatic bullet arrangement device for electronic target testing. Background Technology

[0002] An electronic target testing system is a device that measures and analyzes various parameters of an electronic target through the interaction between a flying bullet and the target, thereby evaluating the target's performance. Its working principle involves creating a detection zone using an invisible light curtain. When a bullet passes through this zone, a photoelectric sensing mechanism is triggered. Based on the test results of the electronic target on the bullet, key performance parameters such as the target's response sensitivity, signal transmission delay, and parameter recognition accuracy are obtained, thus completing a precise test of the electronic target. This system has advantages such as non-contact measurement, fast response speed, and high testing accuracy, and is widely used in areas such as performance verification of target drones for ammunition development, parameter calibration of electronic targets for weapon equipment adaptation, and performance evaluation of target drones used in shooting training.

[0003] In existing electronic target testing systems, bullet loading and firing typically employ pneumatic feeding, where compressed air transports the bullet from the storage device to the firing end for direct firing. However, this design, which integrates the bullet transport and firing processes, has certain technical drawbacks. Due to spatial constraints between the loading device and the firing end, the air pipes used for pneumatic feeding are often difficult to maintain in a straight line, inevitably resulting in bends. These bends lead to two problems: first, the bullet experiences significant friction as it passes through the bends in the air pipes, which over time can cause wear on the inner walls of the pipes, severely impacting their lifespan and increasing equipment maintenance costs; second, the frictional resistance experienced by the bullet in the bend area interferes with its velocity, causing the actual firing speed to deviate from the preset value, thus affecting the accuracy and reliability of the electronic target testing results. Summary of the Invention

[0004] This invention provides an automatic bullet arrangement device for electronic target testing with independent transport and firing steps, so as to reduce the impact of the transport step on the bullet firing speed and ensure the accuracy of the bullet firing speed.

[0005] The technical solution is as follows: An automatic bullet arrangement device for electronic target testing includes: a mounting frame; a conveying device disposed on the mounting frame for conveying bullets; a mounting tube fixedly connected inside the mounting frame, the tube having a transfer port, the conveying device being connected between a bullet adding device and the transfer port; a conveying tube movably connected inside the mounting tube for conveying bullets, which can be displaced and rotated relative to the mounting tube, the conveying tube having a storage port for storing bullets; a cylinder fixedly connected to the mounting frame, the cylinder's extension rod being rotated and connected to the conveying tube to control the axial displacement of the conveying tube relative to the mounting tube; and a cylinder for conveying bullets. The outer wall of the delivery tube is decorated with spiral patterns, and a corresponding convex ball is located on the inner wall of the mounting tube. The convex ball cooperates with the spiral patterns to convert the relative displacement between the delivery tube and the mounting tube into relative rotation between them. The acceleration tube is fixedly connected to the mounting frame, and its end is fixedly connected to the launching end and internally communicates with it. A docking port is provided between the acceleration tube and the mounting tube. The delivery tube switches the control storage port between two states, "docked with the transfer port" and "docked with the docking port", through reciprocating and rotating movements. An air pump is fixedly connected to the mounting frame and is connected to the acceleration tube to provide launching power for the bullets entering the acceleration tube.

[0006] Preferably, the axial distance between the transfer port and the docking port is greater than the axial length of the storage port.

[0007] Preferably, the conveying device includes: a mounting cylinder fixedly connected to the mounting frame, the mounting cylinder having a guide groove for guiding bullets; a docking channel fixedly connected between the bullet adding device and the mounting cylinder, for introducing the bullet into the guide groove inside the mounting cylinder; a mounting plate fixedly connected to the bottom of the mounting cylinder, having a conveying port for the bullet to pass through, the guide groove and a transfer port on the mounting tube docking through the conveying port; a spiral conveying rod rotatably connected inside the mounting cylinder, its spiral blades coinciding with the guide groove, the spiral blades pushing the bullet vertically along the guide groove when the spiral conveying rod rotates; and a driving component disposed inside the mounting frame for providing rotational driving force to the spiral conveying rod.

[0008] Preferably, the device further includes two control seats slidably connected to the lower part of the docking channel, which control the opening and closing of the docking channel by displacement actions of separating and closing between them.

[0009] Preferably, the device further includes: a mounting rod fixedly connected to the lower part of the docking channel; a second gear rotatably connected to the mounting rod; a first rack fixedly connected to each control seat, wherein one first rack on each of the two control seats meshes with the second gear in opposite directions; a mounting shaft fixedly connected to the side of the control seat, the mounting shaft being slidably connected to the docking channel; a first return spring fixedly connected between the mounting shaft and the docking channel; a second rack fixedly connected to one of the control seats; and a missing gear coaxially fixedly connected to the screw conveyor rod, which will mesh with the second rack.

[0010] Preferably, the device further includes a limiting block slidably connected to the lower part of the docking channel, located on the front side of the control seat, for changing the inner diameter of the docking channel by displacement.

[0011] Preferably, the limiting block and the mounting rod are slidably connected. The device further includes: a second return spring fixedly connected between the mounting rod and the limiting block; a protrusion fixedly connected to the control seat; and a contact arm fixedly connected to the limiting block, which is provided with an arc-shaped contact surface that cooperates with the protrusion. Through the cooperation between the two, the displacement of the control seat will convert the displacement of the limiting block.

[0012] Preferably, the drive component includes: a motor fixedly connected within the mounting frame; and two meshing first gears, one of which is coaxially fixed to the output end of the motor, and the other is coaxially fixed to the screw conveyor rod.

[0013] The beneficial effects of this invention are as follows: This invention employs a closed-loop transportation method, which on the one hand enables precise bullet delivery and effectively prevents bullet jamming; on the other hand, it avoids air pressure leakage at the acceleration tube, ensuring stable power during the bullet acceleration and firing process and guaranteeing the stability of subsequent target testing. This invention effectively separates the firing and delivery steps, reducing the impact of the delivery step on the bullet firing speed, making the firing speed control more precise, and enabling accurate target testing. Furthermore, by synchronizing the delivery and firing rhythms, it ensures that each bullet completes the delivery, transfer, and firing process according to a preset rhythm, effectively avoiding jamming caused by rhythm misalignment and improving the smoothness of the invention's operation. This invention uses a control seat with precise periodic on / off control, ensuring that bullets enter the mounting cylinder one by one in an orderly manner, preventing multiple bullets from entering simultaneously, and improving the stability and safety of the delivery process. Moreover, the on / off control of the bullet delivery can achieve automatic matching of the operating rhythm without the need for an additional control unit, simplifying the structure of the invention, reducing operational difficulty, and making the invention more convenient to use. This invention employs a precisely rhythmic limiting block that intercepts subsequent bullets when the control seat opens, allowing the current bullet to enter the mounting tube. This prevents multiple bullets from entering simultaneously and causing congestion or stacking, ensuring that only one bullet is allowed to pass through the control seat at a time, further guaranteeing the orderliness and accuracy of bullet delivery.

Detailed Implementation

[0025] The present invention will be further described below with reference to the accompanying drawings and embodiments. To make the structure of the present invention clearer, it should be specifically noted that the accompanying drawings are merely illustrative; the proportions and dimensions of the components in the drawings may be simplified or exaggerated, but this does not affect the understanding of the essential technical solution of the present invention, nor does it constitute a limitation on the scope of protection of the present invention.

[0026] Example: An automatic bullet arrangement device for electronic target testing, such as... Figure 1 As shown, a vibratory guide rail 02 is fixedly installed on the vibratory plate 01. After starting, the bullets can be transported into the vibratory guide rail 02, so that the bullets are arranged in an orderly manner along the vibratory guide rail 02. This device is set between the target machine 04 and the vibratory guide rail 02. After the vibratory plate 01 and the vibratory guide rail 02 add the bullets to this device, the device automatically arranges and adds them to the firing end 03, and fires the bullets from the firing end 03 and through the target machine 04.

[0027] like Figures 1-4 As shown, the system includes: a mounting frame 11; and a conveying device mounted on the mounting frame 11 for conveying bullets. The conveying device includes: a mounting cylinder 12 fixedly mounted on the upper part of the mounting frame 11, with a guide groove 19 for guiding the bullets; a docking channel 13 fixedly mounted between the vibrating guide rail 02 and the mounting cylinder 12, for guiding the bullets output in rows from the vibrating guide rail 02 into the guide groove 19 within the mounting cylinder 12; a mounting plate 14 fixedly mounted on the bottom of the mounting cylinder 12, with a conveying port 15 for the bullets to pass through; and a rotatable spiral conveying rod 16 mounted within the mounting cylinder 12. The spiral blades of the spiral conveyor 16 coincide with the guide groove 19. When the spiral conveyor 16 rotates, its spiral blades push the bullet to move vertically along the guide groove 19. A drive component is set in the mounting frame 11 to provide rotational driving force for the spiral conveyor 16. The drive component includes: a motor 17 fixedly installed in the mounting frame 11; and two meshing first gears 18, one of which is coaxially fixed with the output end of the motor 17 and the other is coaxially fixed with the spiral conveyor 16. When the motor 17 is started, it will provide rotational driving force for the spiral conveyor 16 through the two first gears 18.

[0028] like Figure 2 , Figure 5 and Figure 6As shown, the device also includes: an installation tube 21 fixedly installed in the installation frame 11, with a transfer port 22 on its body, and a guide groove 19 connected to the transfer port 22 via a conveying port 15; a conveying tube 23 movably installed inside the installation tube 21 for conveying bullets, which will move and rotate relative to the installation tube 21, and a storage port 25 for storing bullets is opened on its body, and the storage port 25 completes the bullet transfer through the movement of the conveying tube 23; a cylinder 24 fixedly installed on the installation frame 11, the telescopic rod of the cylinder 24 being rotatably connected to the conveying tube 23 for controlling the axial displacement of the conveying tube 23 relative to the installation tube 21; a semi-circular spiral 26 is provided on the outer wall of the conveying tube 23, and a convex ball 27 is provided at a corresponding position on the inner wall of the installation tube 21, the convex ball 27 cooperating with the spiral 26, when the conveying tube 23 completes one reciprocating movement relative to the installation tube 21, the convex ball 27 and the spiral 26 The action will drive the delivery tube 23 to complete a half-turn rotation in both directions relative to the mounting tube 21; the acceleration tube 28, which is fixedly installed in the mounting frame 11, is located directly below the mounting tube 21, and its end is fixedly connected to the launching end 03 and communicates internally; a docking port 210 is provided between the acceleration tube 28 and the mounting tube 21. The delivery tube 23 controls the storage port 25 to switch between two states: "docking with the transfer port 22" and "docking with the docking port 210" through reciprocating and rotating actions. Moreover, the axial distance between the transfer port 22 and the docking port 210 is greater than the axial length of the storage port 25. That is, during the transfer of the storage port 25 with the delivery tube 23, there will be a closed state in which the storage port 25 does not dock with either the transfer port 22 or the docking port 210; the air pump 29, which is fixedly installed in the mounting frame 11, is connected to the acceleration tube 28 and is used to provide firing power for the bullets entering the acceleration tube 28.

[0029] The test bullets are loaded into the vibratory feeder 01, and a collection box is placed on one side of the target machine 04 to retrieve the bullets fired from the firing end 03. After the vibratory feeder 01 is started, it works with the vibratory guide rail 02 to output the bullets in an orderly row. The bullets enter the guide groove 19 in the mounting cylinder 12 through the docking channel 13. Then, under the layer delivery action of the spiral blades of the rotating spiral conveyor rod 16, the bullets are transported vertically downward along the guide groove 19 to the conveying port 15. When a bullet passes through the delivery port 15 and the transfer port 22, if the delivery pipe 23 moves to the point where the storage port 25 is directly opposite the transfer port 22, the bullet will fall into the storage port 25. Immediately afterwards, the cylinder 24 controls the delivery pipe 23 to move axially along the mounting pipe 21, transferring the storage port 25 to dock with the docking port 210. Therefore, when setting the operating parameters, it is only necessary to control the frequency of the reciprocating motion of the delivery pipe 23 to be consistent with the frequency of each rotation of the spiral delivery rod 16 to unify the bullet delivery rhythm. For each bullet delivered by the spiral delivery rod 16, the corresponding spiral delivery rod 16 delivers one layer, and the delivery pipe 23 synchronously performs a complete reciprocating motion, including axial displacement and rotation, thereby transferring the current bullet to the acceleration pipe 28 and resetting it, preparing for the delivery of the next bullet.

[0030] When the storage port 25 rotates to align with the docking port 210, the bullet passes through the docking port 210 under the action of gravity and enters the acceleration tube 28. The air pump 29 injects high-pressure gas into the acceleration tube 28, propelling the bullet through the acceleration tube 28 at high speed and ejecting it from the launching end 03. The target machine 04 will detect the bullet's cross-sectional parameters in real time and reverse-engineer the target machine 04's own response sensitivity, signal transmission delay, and parameter recognition accuracy performance parameters to complete the accurate testing of the electronic target. Finally, the fired bullet falls into the collection box.

[0031] This device adopts a closed transportation method, which can not only achieve precise delivery of bullets and prevent omissions, but also avoid air pressure leakage at the acceleration tube 28. At the same time, the firing step and the delivery step are effectively separated, making the control of the firing speed more precise and ensuring the testing accuracy of the target machine 04. In addition, through the above-mentioned synchronous control, it can ensure that each bullet can complete the delivery, transfer and firing process according to a fixed rhythm, avoiding jamming problems caused by rhythm misalignment.

[0032] like Figure 2 , Figure 7 and Figure 8 As shown, the device further includes: two control seats 31 slidably mounted on the lower part of the docking channel 13, which control the opening and closing of the docking channel 13 through displacement actions of separating and closing between them; a mounting rod 32 fixedly mounted on the lower part of the docking channel 13; a second gear 33 rotatably mounted on the mounting rod 32; a first rack 34 fixedly mounted on each control seat 31, with one first rack 34 on each of the two control seats 31 meshing with the second gear 33 in opposite directions; a mounting shaft 35 fixedly mounted on the side of the control seat 31, which is slidably mounted to the docking channel 13; a first return spring 36 fixedly mounted between the mounting shaft 35 and the docking channel 13, which is sleeved on the mounting shaft 35; a second rack 37 fixedly mounted on one of the control seats 31; and a missing gear 38 coaxially fixedly mounted on the screw conveyor rod 16, which will mesh with the second rack 37.

[0033] When the screw conveyor rod 16 rotates, the notched gear 38 rotates synchronously. The notch in the notched gear 38 will cause it to form an intermittent meshing structure with the second rack 37. Therefore, when the notched gear 38 rotates to mesh with the second rack 37, it will cause the control seat 31 connected to the second rack 37 to move outward relative to the docking channel 13. In conjunction with the reverse transmission action of the second gear 33 and the first rack 34, the other control seat 31 will move synchronously and in the opposite direction. Then the two control seats 31 will separate from each other, the first return spring 36 will be compressed, and at this time, the docking channel 13 will open. When the first gear 38 disengages from the second rack 37 and loses its control over the control seat 31, the two control seats 31 move closer together under the restoring action of the first return spring 36, closing the docking channel 13 and blocking the bullet delivery path. That is, through the above transmission control, the opening and closing action of the control seat 31 is precisely matched with the rotation cycle of the screw conveyor 16, ensuring that the control seat 31 completes one opening and closing cycle for every bullet delivered by the screw conveyor 16, thereby achieving precise control over the bullet delivery.

[0034] Through the aforementioned periodic on / off control, the bullets are ensured to enter the mounting cylinder 12 in an orderly manner, effectively avoiding the problem of jamming of the spiral conveyor rod 16 due to multiple bullets entering at the same time, thus improving the stability and reliability of the conveying process of this device. The aforementioned on / off control of bullet conveying can achieve automatic matching of the operating rhythm without the need for an additional control unit, which is simple in structure and convenient to operate.

[0035] like Figure 2 , Figure 9 and Figure 10 As shown, the device also includes: a limiting block 41 slidably installed at the lower part of the docking channel 13, which is slidably installed with the mounting rod 32. The limiting block 41 is located on the front side of the control seat 31 and is used to change the inner diameter of the docking channel 13 by displacement; a second return spring 42 fixedly installed between the docking channel 13 and the limiting block 41, which is sleeved on the mounting rod 32; a protrusion 44 fixedly installed on the control seat 31; and contact arms 43 fixedly installed on both sides of the limiting block 41, which are provided with arc-shaped contact surfaces that cooperate with the protrusion 44. Through the cooperation between the two, the displacement of the control seat 31 will convert the displacement of the limiting block 41.

[0036] When the control seats 31 are separated, the protrusions 44 connected to them cooperate with the arc-shaped contact surfaces on the contact arms 43 to push the limiting block 41 into the docking channel 13. The second return spring 42 is compressed, and the portion of the limiting block 41 extending into the docking channel 13 reduces the effective inner diameter of the docking channel 13, thereby preventing subsequent bullets from entering the area of ​​the control seats 31. This ensures that while the control seats 31 are open and allow the current bullet to enter the mounting cylinder 12, subsequent bullets are intercepted, avoiding congestion or stacking caused by multiple bullets entering at the same time. This ensures that only one bullet can pass through the control seats 31 at a time, further guaranteeing the orderliness and accuracy of bullet delivery. When the control seats 31 complete the delivery action and begin to close and reset, the protrusions 44 retract with the control seats 31 and no longer push the contact arms 43. The second return spring 42 then returns to its original position, causing the limiting block 41 to slide and reset out of the docking channel 13, releasing the limiting block 41 from blocking subsequent bullets. The next bullet can then be added to the area of ​​the control seats 31 to wait for the delivery control cycle.

[0037] The above description is merely a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in the present invention should be included within the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be determined by the scope of the claims.
