[0039] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.
[0040] Example 1: Please refer to Figure 1-10 The present invention provides a technical solution: a performance testing device for a lightweight spare tire cover, comprising a frame 1 and a remote control terminal. The frame 1 includes two parallel frames of different heights. A conveyor belt 2 is installed on the upper part of the higher frame. The conveyor belt 2 is bidirectional and is used to transport the spare tire cover. A support plate 3 is fixedly connected on the upper part of the lower frame to support the components required for the performance testing of the spare tire cover.
[0041] The remote control system includes a data processing system, an equipment control system, and a monitoring system. The data processing system uses professional algorithms and models to perform in-depth analysis and processing of the detection parameters. The equipment control system uses automated circuit control and signal transmission to precisely control the electrical components in the detection process. The monitoring system consists of multiple cameras with high-definition shooting and intelligent image recognition functions. It can be installed on the detection equipment or outside the equipment to monitor the detection status in the equipment and to accurately position the spare tire cover.
[0042] like Figure 1-3 As shown, a base 4 is installed above the support plate 3, and a guide rail 5 is installed on the upper surface of the base 4. A positioning plate 6 is slidably connected to the guide rail 5 via a slider. The positioning plate 6 is located at one end of the conveyor belt 2, which facilitates the feeding of the spare tire cover. A positioning block is installed in the middle of the positioning plate 6, and a lead screw is inserted through the middle of the positioning block. The lead screw bearing is connected to the inside of the base 4, and one end of the lead screw is fixedly connected to a rotary motor via a coupling. The rotary motor is installed inside the base 4. The rotary motor drives the lead screw to rotate by rotating forward and backward, thereby driving the positioning plate 6 to move smoothly along the direction of the guide rail 5.
[0043] A first mounting base 7 is provided on the side of the positioning plate 6 away from the conveyor belt 2. The first mounting base 7 is installed above the base 4. A cylinder 8 is fixedly connected above the first mounting base 7. A push plate 9 is fixedly connected to the movable end of the cylinder 8. Clamping plates are installed at both ends of the push plate 9. The clamping plates are driven by a transmission structure composed of a micro motor and a lead screw and nut pair (not shown in the figure). The speed of the micro motor can be adjusted by a remote control terminal, thereby precisely controlling the opening and closing degree and clamping force of the clamping plates. The clamping force is adjusted according to the material and size of the spare tire cover, thereby clamping the spare tire cover on the positioning plate 6. At the same time, the spare tire cover on the positioning plate 6 can be pushed onto the conveyor belt 2 to achieve the delivery effect.
[0044] like Figure 3-5 As shown, two support columns 10 are fixedly connected to the top of the base 4, a top plate 11 is fixedly connected to the top of the support columns 10, an electric slide rail 12 is fixedly connected to the bottom of the top plate 11, and a mounting bracket 13 is slidably connected to the bottom of the electric slide rail 12 via a slider 2 for protection.
[0045] like Figure 6-8As shown, a detection assembly is installed inside the mounting frame 13. The detection assembly includes a rotating shaft 14, with both ends of the rotating shaft 14 bearingly connected to the inner walls of opposite sides of the mounting frame 13. A roller 15 is fitted onto the rotating shaft 14. Two connecting rods 16 are also hinged to the inner walls of opposite sides of the mounting frame 13. The other end of the connecting rods 16 is fixedly connected to a rotating shaft 141, with a roller 17 fitted onto the rotating shaft 141. A rotary motor 2 is installed inside both the rotating shaft 14 and the rotating shaft 141. The output shafts of the rotary motor 2 inside the rotating shaft 14 and the rotating shaft 141 are fixedly connected to the roller 15 and the roller 17 respectively via couplings, thereby driving the rotation of the roller 15 and the roller 17. The two rotary motors 2 are respectively located in... Figure 7 As shown, drive roller 15 rotates counterclockwise, and roller 2 17 rotates clockwise;
[0046] Connecting rod 16 is hinged to connecting rod 18 on the side away from pivot 141. Two pneumatic rods 19 are fixedly connected to the inner walls of the mounting bracket 13 on both sides. The end of connecting rod 18 away from connecting rod 16 is fixedly connected to the telescopic end of pneumatic rod 19. When pneumatic rod 19 extends or retracts, connecting rod 18 is pushed out or retracted, causing roller 17 to rotate around the end of connecting rod 16 away from roller 15, thereby controlling the distance between roller 17 and roller 15.
[0047] Furthermore, the mounting bracket 13 is provided with a sliding groove 131, and a displacement rod 20 is slidably connected in the sliding groove 131. The displacement rod 20 is located between roller 15 and roller 27. When roller 27 contacts the displacement rod 20, the rotation of roller 15 and roller 27 will drive the displacement rod 20 to rise. When it rises to a certain height, the pneumatic rod 19 retracts, and the connecting rod 2 18 retracts, so that roller 2 17 moves away from the displacement rod 20. At this time, the displacement rod 20 achieves the effect of falling quickly.
[0048] The bottom of the displacement rod 20 is fixedly connected to a connecting bracket 21, such as... Figure 9-10 As shown, a support frame 22 is fixedly connected to the bottom of the connecting frame 21. The bottom of the support frame 22 has an arc-shaped plate structure. A rotating rod 23 is connected to the middle bearing of the support frame 22. A gear 24 is sleeved on the upper part of the rotating rod 23. One end of the rotating rod 23 is fixedly connected to a rotary motor 3 through a coupling, so that the rotating rod 23 rotates and drives the gear 24 to rotate. A rack 25 is slidably connected above the arc-shaped plate at the bottom of the support frame 22. The rack 25 is an arc-shaped rack and meshes with the gear 24. A hammer head 26 is fixedly connected to the end of the rack 25 for striking the spare tire cover, thereby achieving the effect of pressure detection on the spare tire cover. When the rotary motor 3 drives the gear 24 to rotate, the rack 25 flips, which in turn causes the hammer head 26 to flip.
[0049] Furthermore, a round head 261 is fixedly connected to one end of the hammer head 26, and a flat head 262 is fixedly connected to the other end of the hammer head 26. The orientation of the round head 261 and the flat head 262 can be switched by flipping the rack 25 to adapt to different testing needs, such as selecting a suitable hammer head shape for different materials and structures.
[0050] like Figure 1-4 As shown, a horizontal plate 27 is fixedly connected to one side of the top plate 11. The horizontal plate 27 is fixedly connected to the base 4 above by a vertical plate support. A hydraulic cylinder 28 is installed in the middle of the horizontal plate 27. The movable end of the hydraulic cylinder 28 is fixedly connected to a pressure plate 29 by a rod, which is used to perform overall pressure resistance testing on the spare tire cover.
[0051] An extension plate 30 is fixedly connected to the side of the conveyor belt 2 away from the horizontal plate 27. A second mounting base 31 is installed on the extension plate 30. A second cylinder 32 is fixedly connected to the second mounting base 31. A second push plate 33 is fixedly connected to the movable end of the second cylinder 32 for pushing out the spare tire cover that fails the inspection. A recycling trough 34 is provided on the side of the conveyor belt 2 away from the extension plate 30. The recycling trough 34 is fixedly connected to the top of the frame 1, so that the spare tire cover pushed out by the second push plate 33 will be collected through the recycling trough 34.
[0052] In this embodiment, the spare tire cover is placed above the conveyor belt 2 and fed in by automated equipment such as a robotic arm. When the camera detects that the spare tire cover has been conveyed to one end near the positioning plate 6, cylinder 8 drives the extension of push plate 9 and clamps the spare tire cover. Then, cylinder 8 retracts push plate 9 and releases the spare tire cover, so that the spare tire cover is located above the center of the positioning plate 6. At this time, the rotary motor drives the spare tire cover to be conveyed to the area below the pressure plate 29 through the positioning plate 6. After positioning, hydraulic cylinder 28 drives the pressure plate 29 to descend and contact the spare tire cover, applying a certain pressure. This pressure is preset in advance through the remote control terminal and is within the bearing capacity of the spare tire cover, realizing the overall pressure resistance test of the spare tire cover. At this time, the condition of the spare tire cover is viewed through the camera. If the spare tire cover does not show obvious deformation or damage according to the camera feedback, the spare tire cover is conveyed to the area below the top plate 11 through the positioning plate 6. Select round head 261 or The flat head 262 points downwards and, through the electric slide rail 12, in conjunction with the rotary motor and guide rail 5, drives the hammer head 26 to move to different areas above the spare tire cover to perform area-specific impact testing. At the same time, the condition of the spare tire cover is monitored by a camera. If the camera indicates no obvious deformation or damage, the cylinder 8 drives the push plate 9 to push the spare tire cover onto the conveyor belt 2 for delivery. If either the overall or area-specific impact testing detects deformation or damage to the spare tire cover via the camera, the spare tire cover is deemed unqualified. After being pushed onto the conveyor belt 2 by the cylinder 8 and the push plate 9, the spare tire cover is pushed out onto the push plate 33 by the cylinder 32 and discharged into the recycling tank 34 for collection. During the testing process, all test data is transmitted in real-time to the remote control data processing system for storage and analysis, facilitating subsequent performance evaluation and quality traceability.
[0053] Through the above embodiments, the entire process is automated, accurately conveying and positioning the spare tire cover. The pressure plate 29 and hammer 26 are used to complete the overall and regional pressure resistance test. The hammer 26 can be switched and the force and frequency can be adjusted. The monitoring system provides real-time positioning and feedback, and the data system analyzes and stores the data. Defective products are automatically pushed to the recycling tank 34, while qualified products are sent out. This equipment is accurate, efficient, and can trace data, meeting the testing requirements.
[0054] Example 2: Based on Example 1, to ensure the production quality of the spare tire cover, a more comprehensive pressure resistance test is performed on the spare tire cover. The following structure is added: a hydraulic rod is installed above the first mounting base 7. The movable end of the hydraulic rod is fixedly connected to the outside of cylinder 8, thereby driving the cylinder 8 and push plate 9 to rise and fall through the hydraulic rod. At the same time, a rotary motor 4 is added to the movable end of cylinder 8. The output end of rotary motor 4 is fixedly connected to push plate 9 through a coupling, thereby realizing the flipping of push plate 9. When the spare tire cover undergoes the overall pressure resistance test, that is, after the pressure plate 29 squeezes the spare tire cover, if the camera feedback shows that the spare tire cover has local deformation, it indicates that the spare tire cover has a local weakness. At this time, the camera locates the deformed area, and drives rotary motor 1 to move the positioning plate 6 to below the top plate 11, drives push plate 9 to extend and clamp the spare tire cover. At this time, the hydraulic rod drives push plate 9 to rise and flip the spare tire cover, so that the original bottom surface of the spare tire cover is facing upwards, and the camera continues to locate the deformed area.
[0055] If the deformation is a slight dent with a small area, adjust the round head 261 to face downwards, and set the striking force of the round head 261 to 60% to 70% of that of the flat head 262 to avoid secondary damage due to excessive force. Driven by the electric slide rail 12, the round head 261 is positioned above the deformed area, allowing for concentrated striking. The small contact area of the round head 261 allows it to target the dented area precisely. Through n1 consecutive, even taps, it promotes slight material recovery and extension at the deformed area.
[0056] If the deformation results in a large area of bulge or crease, adjust the flat head 262 downwards and drive it to move above the deformed area via the electric slide rail 12. This ensures that when the spare tire cover is struck by the hammer head 26, both the directly impacted area and its surrounding area are struck, allowing for better integration between the impacted area and its surroundings. After the deformation area is struck n2 times by the detection component:
[0057] Scenario 1: If the deformation is not improved, or if other deformations appear on the surface of the spare tire cover after being hammered, then the spare tire cover is of substandard quality. It can be pushed onto the conveyor belt 2 by pusher plate 1 9 and then sent to pusher plate 2 33 and pushed out into the recycling tank 34.
[0058] Scenario 2: If the deformed area becomes flat and no new deformation appears in other areas of the spare tire cover, then the spare tire cover has good plasticity. In this case, the positioning plate 6 is sent back to the pressure plate 29, and the spare tire cover is subjected to the same overall pressure resistance test as the first time. If the spare tire cover no longer deforms or is damaged at this time, then the spare tire cover is of qualified quality and can continue to be used. If the spare tire cover recovers its deformation but deforms or is damaged again after being squeezed by the pressure plate 29, it indicates that the spare tire cover can no longer resist pressure after being squeezed and recovered once. In this case, the spare tire cover is of unqualified quality and is sent out to be recycled into the recycling tank 34 by the push plate 2 33.
[0059] Through the above embodiments, the addition of hydraulic rods and rotary motors enables the lifting and flipping of the push plate. For local deformations that appear during the overall pressure resistance test, different tools are used to tap according to the type of deformation, which further improves the pertinence and accuracy of the test and ensures the production quality of the spare tire cover.
[0060] Example 3: Based on the above examples, in order to further improve the quality of the spare tire cover and test its anti-slip effect, specifically, a pressure sensor 2 is added inside the flat head 262 to detect the surface contact between the flat head 262 and the spare tire cover; a pressure sensor 1 is added inside the round head 261 to detect the surface contact between the round head 261 and the spare tire cover. At this time, the hammer head 26 is adjusted to a position where the round head 261 faces downwards, and the positioning plate 6 is located below the top plate 11. When the roller 15 is not in contact with the displacement rod 20, the round head 261 naturally descends and contacts the upper surface of the spare tire cover. At this time, the first drive motor runs slowly, which slowly moves the spare tire cover to below the pressure plate 29. During this process, the first roller 15 contacts the displacement rod 20, causing the displacement rod 20 to rise slowly. At the same time, the second drive motor drives the gear 24 to rotate slowly, causing the rack 25 to flip, so that the round head 261 is always in contact with the surface of the spare tire cover. The friction force generated when the round head 261 contacts the spare tire cover is converted into a force value P by the pressure sensor. The contact pressure between the spare tire cover and the round head 261 is set as p (p is pre-calibrated based on the anti-slip test of the qualified cover under flat head contact).
[0061] When P ≥ p, it indicates that the friction between the surface of the spare tire cover and the round head 261 meets the anti-slip requirements, and the anti-slip performance is qualified. At this time, continue to drive the rotary motor to send the spare tire cover under the pressure plate 29 to complete the subsequent routine inspection process. If all other subsequent inspection items are qualified, the overall quality of the spare tire cover is qualified; if there are problems with other inspection items, they shall be judged according to the corresponding inspection standards.
[0062] When P < p, it indicates that the anti-slip performance of the spare tire cover is insufficient. At this time, the rotary motor stops running. Since the contact area between the flat head 262 and the spare tire cover is larger than that of the round head 261, it can further verify the anti-slip performance of the cover surface under a larger contact area. Therefore, it is used as a supplementary judgment basis for the anti-slip performance test. At this time, the control hammer 26 is switched to the flat head 262 facing down state, and the driving positioning plate 6 drives the spare tire cover to reset. The flat head 262 naturally descends and contacts the cover surface. Then, the rotary motor is driven to slowly move the cover at the same speed. The contact force value Q is fed back by the pressure sensor 2 of the flat head 262. The qualified threshold is set to q ( q is based on the pre-calibrated anti-slip test of a qualified cover plate under flat-head contact. When Q≥q, it indicates that the anti-slip performance of the cover plate meets the standard under large contact area, and can be judged comprehensively in combination with the round-head test results (such as being considered qualified in scenarios where slight differences in anti-slip performance are allowed). When Q<q, it is confirmed that the anti-slip performance of the cover plate is unqualified. A signal indicating unqualified anti-slip performance is sent through the remote control terminal. At the same time, push plate 9 is driven to extend and clamp the spare tire cover plate, push it to the conveyor belt 2, and after being transported to push plate 33, it is pushed out by push plate 33 into the recycling tank 34. At the same time, the data processing system records the unqualified information, which is convenient for subsequent traceability and analysis of the reasons for insufficient anti-slip performance.
[0063] Through the above embodiments, pressure sensor one and pressure sensor two are respectively installed in the round head 261 and flat head 262 of the hammer head 26. First, the round head 261 contacts the spare tire cover, and the contact force is detected during the movement of the cover to determine the anti-slip performance. At the same time, the flat head 262 is switched to perform supplementary testing. The contact force of the flat head 262 is used to further verify the anti-slip performance of the spare tire cover, which effectively improves the comprehensiveness and reliability of the anti-slip performance test.
