Description

Technical Field

[0001] This invention relates to the field of new energy vehicles, specifically to a device and method for testing the strength of new energy vehicle wheels. Background Technology

[0002] With the rapid development of the new energy vehicle industry, the requirements for vehicle safety performance are increasing. As a key load-bearing component in the vehicle's driving system, the strength of the wheels directly affects the safety and reliability of the entire vehicle. However, traditional wheel strength testing methods have many technical limitations and are difficult to meet the testing needs of modern new energy vehicles.

[0003] First, traditional inspection methods rely solely on visual inspection and measurement of groove width and depth. For more accurate inspections, the tires must be removed from the vehicle and sent for testing. This process is time-consuming, inconvenient, and severely impacts the normal use of the vehicle.

[0004] Secondly, even though some testing equipment can test tire strength without disassembling the tires, the testing often overlooks the dynamic impact of the vehicle's shock absorption system on the wheel's stress state. In actual driving, the operation of the shock absorption system changes the stress distribution on the wheel, causing the actual strength of the wheel to be less than the test result, thus affecting safety. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this invention provides a new energy vehicle wheel strength testing device and method that can handle vehicles and wheels of different sizes, observe the wheel's condition, automatically keep the observation area clean, and eliminate the influence of the vehicle's shock absorption system on the test results during the compression test, thus avoiding affecting the test results.

[0018] Preferably, four brackets are provided, respectively located on both sides of the upper end of the machine body, with each pair of brackets forming a group and symmetrically distributed.

The lifting plate is slidably connected to the inner cavity of the sleeve.

[0022] A method for testing the strength of a new energy vehicle wheel, applicable to any of the above-mentioned new energy vehicle wheel strength testing devices, comprising:

[0023] S1: Auxiliary positioning: Before the inspection, the vehicle moves above the machine body. At this time, the track runs and drives the positioning block to move to a position parallel to the center of the turntable, so that the vehicle's wheels rest on the side of the turntable.

[0024] S2: Lifting detection. After the vehicle is moved into position, the lift drives the vehicle to rise. At this time, the positioning block is driven by the track to move from the front side of the wheel to the rear side, and the surface of the tire is checked by the detection light.

[0025] S3: Limiting contact, the lift raises the vehicle so that the center of the wheel is parallel to the center of the turntable. Then the moving part drives the turntable to approach the wheel. Then the slider slides along the inner cavity of the turntable until it is in contact with the outer surface of the wheel. After contact, the turntable rotates, driving the two sets of positioning rods to move to the position above the wheel.

[0026] S4: Strength test. After the positioning rod moves above the wheel, the lifting plate drives the bracket to rise and press against the bottom of the wheel. At this time, because of the limitation of the positioning rod, the wheel cannot transmit the force to the shock absorption structure, thus performing a precise strength test.

[0027] S5: After disembarking, once the inspection is complete, the drive positioning rod and bracket will reset, and then the vehicle will be driven to descend and reset. At this point, the positioning block has moved to the rear of the wheel and can no longer restrict the wheel's rolling. The vehicle can then be driven away from the machine.

[0028] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0029] The moving part and limiting part of the present invention enable the device to handle wheels of different sizes, thereby improving the breadth and practicality of the inspection. During inspection, the moving frame slides above the machine body, bringing the turntable close to the wheel. After it gets close, the slider is driven to move in the inner cavity of the turntable, so that the positioning rod fits against the outer rim of the wheel. After the positioning rod fits, the turntable is driven to rotate, so that the positioning rod moves above the wheel, thereby limiting the upward movement of the wheel and preventing the force from being transmitted to the vehicle's shock absorption components during subsequent inspection, which would affect the accuracy of the inspection.

[0030] The positioning and detection units of this invention can observe the state of the wheel and automatically keep the observation area clean to avoid dust and other factors affecting the detection of the wheel. In use, the vehicle is first positioned at the designated location by the positioning block for detection. Before the vehicle is detected, the positioning block can be driven to move under the wheel and the current state of the wheel is detected by the detection light. During the movement of the positioning block, the spool is driven to rotate by the rack, which in turn drives the wiping plate to move above the detection light for self-cleaning, keeping the detection light clean and avoiding affecting the observation effect.

[0031] The lifting and limiting parts of this invention can adapt to vehicles of different widths and eliminate the influence of the vehicle's shock absorption system on the test results during the compression test. Before the test, the lifting plate is moved into a suitable housing according to the width of the vehicle. During the test, the lifting plate and the bracket are driven to rise and compress the tire. At the same time, the positioning rod restricts the tire from moving upward, thereby allowing the tire's strength to be tested separately. This avoids the vehicle's shock absorption system components from affecting the test results. In addition, the tire can be rotated multiple times during the test to prevent uneven stress on a certain part of the tire from affecting the integrity of the test. Attached Figure Description

[0050] It is readily understood that, based on the technical solution of this invention, those skilled in the art can propose various interchangeable structural methods and implementations without altering the essential spirit of the invention. Therefore, the following detailed embodiments and accompanying drawings are merely illustrative examples of the technical solution of this invention and should not be considered as the entirety of the invention or as limitations or restrictions on the technical solution of this invention. Example

[0051] like Figures 1 to 4 , Figures 8 to 10 , Figures 14 to 15 As shown, this is the first embodiment of the present invention, which provides a new energy vehicle wheel strength testing device, comprising:

[0052] The machine body 10 has a lift 12 installed inside it, and a vehicle 13 is mounted on the lift 12.

[0053] The movable part 20 includes a movable frame 23, which is disposed above the body 10, and a turntable 26 is disposed inside the movable frame 23.

[0054] The limiting part 30 includes a slider 32, which is disposed inside the turntable 26. A positioning rod 33 is fixedly connected to the outside of the slider 32, and the positioning rod 33 contacts the wheel of the vehicle 13.

[0055] The positioning part 40 includes a bracket 41, on which a track 42 is provided;

[0056] The detection unit 50 includes a positioning block 51, a detection light 53 and a wiping plate 54 on the positioning block 51, pull ropes 55 connected to both sides of the wiping plate 54, a wire reel 57 in the inner cavity of the positioning block 51, the pull ropes 55 placed in the wire reel 57, and a rack 59 on the bracket 41, and the wire reel 57 is connected to the rack 59.

[0057] The lifting part 60 includes a housing 61 connected to the lower part of the bracket 41, and a lifting plate 64 is provided inside the housing 61.

[0058] The positioning block 51 is divided into two states according to the detection steps of the vehicle 13. The first state is when the vehicle 13 has not yet been detected. At this time, the track 42 drives the positioning block 51 to move in front of the vehicle 13, making the positioning block 51 parallel to the center of the turntable 26, so that the vehicle 13 stops moving when it moves under the positioning block 51.

[0059] Second state: When vehicle 13 is being inspected, track 42 drives positioning block 51 to pass under vehicle 13 and drives detection light 53 to observe vehicle 13.

[0060] When the positioning block 51 moves, the spool 57 is driven to rotate by the rack 59, which in turn drives the pull rope 55 and the wiping plate 54 to move above the detector light 53.

[0061] It should be noted that, in order to ensure the normal use of the device, an external control component should be installed to control the normal operation of each component;

[0062] When installing the device, ensure that the bottom surface of the body 10 is parallel to the ground surface to ensure the stability of the device.

[0063] In this embodiment, during use, the positioning block 51 is moved to a position parallel to the turntable 26, and then the vehicle 13 is moved below the positioning block 51. The lift 12 operates to lift the vehicle 13. At this time, the track 42 drives the positioning block 51 to move. The status of the wheel is observed using the detection light 53. Then, the positioning rod 33 is driven to approach and fit against the underside of the wheel. The turntable 26 rotates and moves the positioning rod 33 above the wheel for limiting. Then, the lifting plate 64 pushes the sleeve 61 and the bracket 41 to rise, squeezing the underside of the tire to perform a squeezing strength test. After completion, the vehicle 13 is lowered and driven out of the machine body 10.

[0064] Please refer to it again. Figures 1 to 2 An equipment box 11 is fixedly installed at the lower end of the body 10. A lift 12 is fixedly installed inside the equipment box 11. The upper end of the lift 12 extends out of the equipment box 11 and the body 10, and the upper end of the lift 12 is in contact with the vehicle 13.

[0065] It should be noted that there should be two sets of lifts 12, distributed above the body 10. This is so that after the front wheels of vehicle 13 are inspected, and after vehicle 13 has moved forward slightly, vehicle 13 can be lifted again to inspect the rear wheels, ensuring the completeness of the inspection.

[0066] Preferably, to ensure the continuity and efficiency of the inspection, the lift 12 can also be set as a movable structure (for example, by adding a high-power electric drive track under the lift 12), so that the vehicle 13 can be moved directly while the lift 12 is raised during the inspection process without having to put the vehicle down, thereby quickly inspecting the rear wheels.

[0067] In this embodiment, the lift 12 raises the vehicle 13 to a suitable height during use, ensuring that the wheels and the turntable 26 are on the same horizontal plane.

[0068] Please refer to it again. Figures 2 to 4 The moving part 20 also includes a fixed frame 21, which is fixedly installed on both sides of the body 10. Electric push rods 22 are fixedly installed on the upper ends of both sets of fixed frames 21. The output end of the electric push rod 22 is close to the body 10 and fixedly connected to a moving frame 23. A limit rod 24 is fixedly connected to the lower end of the moving frame 23. The limit rod 24 is slidably connected to the upper ends of the body 10 and the fixed frame 21. A motor A25 is fixedly installed on the side of the moving frame 23 away from the body 10. A turntable 26 is fixedly connected to the output shaft of the motor A25. The turntable 26 is rotatably connected to the inner cavity of the moving frame 23 through a ball bearing.

[0069] It should be noted that a T-shaped structural block is provided at the lower end of the limiting rod 24, and the structural block is slidably connected to the machine body 10 and the fixed frame 21. This is intended to ensure that when the strength of the compression test is performed, the upward thrust borne by the positioning rod 33 can be transmitted to the moving frame 23 through the turntable 26, and then transmitted to the limiting rod 24 and the machine body 10 through the moving frame 23, so as to ensure the overall stability of the moving frame 23 and avoid damage to the moving frame 23 during the strength test, which would affect its use.

[0070] The lower end of the movable frame 23 is provided with rollers to drive the movable frame 23 to move;

[0071] The turntable 26 and the movable frame 23 are adapted to each other to avoid large gaps that could affect the overall stability of the turntable 26.

[0072] In this embodiment, during testing, the electric actuator 22 drives the moving frame 23 to slide along the upper end of the machine body 10, ensuring that the turntable 26 can accurately approach the wheel. After the positioning rod 33 is in contact with the lower end of the wheel surface, the motor A25 is immediately started, driving the turntable 26 to rotate, thereby adjusting the position of the positioning rod 33 and moving it above the wheel for subsequent compression strength testing.

[0073] Please refer to it again. Figures 4 to 8 The limiting part 30 also includes two sets of slide grooves 31. Both sets of slide grooves 31 are opened in the inner ring of the turntable 26. The inner cavity of both sets of slide grooves 31 is slidably connected to sliders 32. Both sets of sliders 32 are fixedly connected to positioning rods 33.

[0074] Electric screws 34 are fixedly installed in the inner cavities of both sets of slide grooves 31. The middle part of the slider 32 is threaded to the outer ring of the electric screw 34. Limiting grooves 35 are opened in the inner cavities of both sets of slide grooves 31. Limiting blocks 36 are slidably connected in the inner cavities of both sets of sliders 32. Electromagnets 37 are fixedly installed in the inner cavities of both sliders 32. The magnetic attraction surface of the electromagnet 37 is close to the limiting block 36. A switching button 38 is fixedly installed on the upper middle part of the side of the moving frame 23 away from the machine body 10. A protruding rod 39 is fixedly connected to the lower side of the outer ring of the turntable 26 extending out of the moving frame 23. The protruding rod 39 is located below the switching button 38.

[0075] It should be noted that the limiting groove 35 has a toothed structure, and the limiting block 36 also has a toothed structure, so that the limiting block 36 can be inserted into the limiting groove 35 for fixation at any time;

[0076] Both the limiting block 36 and the limiting groove 35 are made of high-strength metal to prevent the limiting block 36 from being damaged during the extrusion strength test, thus affecting the normal use of the device;

[0077] The positioning rod 33 is a round rod structure, which allows it to move smoothly on the outer rim of the tire;

[0078] The electric lead screw 34 is a lead screw structure connected to a servo motor, which is designed to drive the slider 32 to slide within the groove 31 by rotating the lead screw;

[0079] The side of the limiting block 36 facing the electromagnet 37 is provided with a matching magnetic attraction component, which is intended to allow the electromagnet 37 to drive the limiting block 36 to move through the magnetic attraction component.

[0080] The electromagnet 37 should have the function of switching positive and negative poles, and the switching button 38 is a control component. It is designed to switch the positive and negative poles of the electromagnet 37 after pressing the switching button 38, and to switch the positive and negative poles of the electromagnet 37 back to their original state when the switching button 38 is deactivated. In this way, the limit block 36 is driven to move by the principle of like poles attracting and unlike poles repelling.

[0081] The outer end of the protruding rod 39 can trigger the switching button 38. When the turntable 26 rotates to the position rod 33 above the tire, the protruding rod 39 can trigger the switching button 38 to control the electromagnet 37 to switch the positive and negative poles, thereby using the principle of like poles repulsion to drive the limit block 36 to insert into the limit groove 35.

[0082] In this embodiment, during use, the electric lead screw 34 drives the slider 32 to slide along the inner cavity of the groove 31, thereby adjusting the position of the positioning rod 33 so that it can accurately fit the outer surface of the wheel. When the slider 32 moves to the predetermined position, the turntable 26 rotates, causing the positioning rod 33 to move above the wheel. At this time, the protruding rod 39 contacts the switching button 38, causing the magnetic attraction surface of the electromagnet 37 to switch between positive and negative poles, and the magnetic attraction part of the electromagnet 37 and the limiting block 36 to switch to the same pole. At this time, through the principle of like poles repulsion, the limiting block 36 is driven to extend out of the slider 32 and be inserted into the limiting groove 35 for fixation, thereby locking the position of the slider 32 and ensuring that the positioning rod 33 remains stable during the detection process. After the detection is completed, when the turntable 26 resets, the protruding rod 39 will disengage from the switching button 38, causing the electromagnet 37 to release from the disengaged state and switch back to the opposite pole, so that the limiting block 36 can be reset for the next round of detection operation.

[0083] Please refer to it again. Figures 11 to 13 There are four brackets 41, which are respectively set on both sides of the upper end of the machine body 10, and each pair of brackets 41 are symmetrically distributed. The inner cavity of the bracket 41 is connected to the track 42. The inner ring of the track 42 is fixed with a toothed chain 43. The inner cavity of the bracket 41 is fixedly installed with a motor B44. The output shaft of the motor B44 is fixedly connected with a sprocket 45. The outer ring of the sprocket 45 meshes with the inner ring of the toothed chain 43.

[0084] It should be noted that a groove is provided in the middle of the bracket 41, and the toothed chain 43 is slidably connected in the groove, which is intended to ensure the overall flatness of the outer surface of the bracket 41.

[0085] The sides and middle of the bracket 41 are made of high-strength metal, while the track 42 is made of rubber. This is designed so that the bracket 41 can bear the main force when the compressive strength test is performed, and to avoid damage to the bracket 41 that would affect the use of the device.

[0086] The lower end of the inner cavity of the bracket 41 is provided with a through groove, and the sprocket 45 meshes with the toothed chain 43 through the through groove.

[0087] In this embodiment, when in use, motor B44 drives sprocket 45 to rotate, thereby driving toothed chain 43 and track 42 to move synchronously, and then controlling the position of positioning block 51 through track 42.

[0088] Please refer to it again. Figures 14 to 16 The positioning block 51 is slidably connected to the top of the bracket 41, and the two ends of the track 42 are respectively fixedly connected to the two ends of the positioning block 51. A trigger button 52 is fixedly connected to the upper side of the positioning block 51. Two sets of detection lights 53 are fixedly installed in the upper inner cavity of the positioning block 51, and a wiping plate 54 is slidably connected to the upper inner cavity of the positioning block 51. The lower end of the wiping plate 54 is in contact with the top of the detection light 53.

[0089] Pull ropes 55 are fixedly connected to both sides of the wiping plate 54. The inner cavity of the positioning block 51 is rotatably connected to the rotating rod 56 through ball bearings. Two sets of wire reels 57 are fixedly connected to the outer ring of the rotating rod 56. The lower ends of the two sets of pull ropes 55 are respectively fixedly connected to the inner cavities of the two sets of wire reels 57. The lower end of the rotating rod 56 extends out of the positioning block 51 and is fixedly connected to the gear 58. The upper end of the bracket 41 is provided with a strip groove, and a rack 59 is fixedly connected in the strip groove. The outer ring of the gear 58 meshes in the tooth groove of the rack 59.

[0090] It should be noted that the positioning block 51 is displaced by the track 42;

[0091] The two sets of detection lights 53 are a supplementary light and a vision inspection instrument, respectively, designed to observe the depth of the tire grooves and the wear condition of the tire;

[0092] A cover plate is provided on the top of the wiping plate 54, and a cotton swab is placed in the inner cavity of the wiping plate 54. The cotton swab extends out of the wiping plate 54 and contacts the top of the detector light 53. The purpose is to wipe the dust on the top of the detector light 53 with the cotton swab, and the cotton swab can be replaced by opening the cover plate. At the same time, grooves are provided on both sides of the positioning block 51, so that the dust and impurities wiped by the cotton swab can be discharged from the grooves.

[0093] The length of the slot is the movable range of the positioning block 51, which is designed so that when the positioning block 51 moves, the gear 58 will roll on the outer ring of the rack 59, thereby driving the spool 57 to rotate.

[0094] The two sets of pull ropes 55 are wound in different directions inside the coil 57. One set is wound clockwise and the other set is wound counterclockwise. The purpose is to ensure that no matter whether the coil 57 rotates in the forward or reverse direction, one set of pull ropes 55 will always be released and the other set of pull ropes 55 will be tightened, thereby driving the wiper plate 54 to move.

[0095] During the detection process, the positioning block 51 needs to move frequently, which causes it to move left and right continuously. In the process of moving left and right, the coil 57 is continuously driven to rotate in the forward and reverse directions, thereby keeping the detector lamp 53 clean.

[0096] Preferably, to avoid the wiping plate 54 obstructing the field of view of the detector lamp 53, each group of detector lamps 53 should be equipped with two camera ports (or lighting ports) distributed at both ends of the detector lamp 53, so that no matter how the wiping plate 54 moves, there will always be one camera port (or lighting port) exposed, thus avoiding affecting the detection work;

[0097] The positioning block 51 should have a built-in alarm component or an external prompting component, designed to prompt or sound an alarm when the wheel touches the trigger button 52, thereby indicating that the wheel has reached the designated position and facilitating positioning.

[0098] The height of the positioning block 51 should be lower than the lowest point of the moving frame 23 to avoid the vehicle 13 being raised too low, which would prevent the positioning block 51 from passing under the wheels and affect the normal use of the device.

[0099] In this embodiment, before inspection, the drive positioning block 51 is moved to the front of the vehicle 13 and parallel to the center of the turntable 26. When the vehicle 13 moves below the positioning block 51, the trigger button 52 is activated to indicate that the vehicle 13 has reached the designated position, and then the lift 12 can be used to lift the vehicle 13. During inspection, the drive positioning block 51 is moved so that the detection light 53 is aimed at the wheel surface for observation, detecting the grooves of the wheel and the condition of the tire. During the movement of the positioning block 51, the gear 58 rolls on the surface of the rack 59, thereby driving the rotating rod 56 and the coil 57 to rotate synchronously. The rotation of the coil 57 releases one set of pull ropes 55 while retracting another set of pull ropes 55, causing the wiping plate 54 to slide above the detection light 53, removing dust or dirt from the surface of the detection light 53, ensuring that the detection light 53 maintains a clear field of vision throughout the inspection process, thereby improving the accuracy of the inspection results.

[0100] Please refer to it again. Figures 9 to 10 The sleeve 61 is fixedly connected to the lower end of each set of brackets 41, and the sleeves 61 between adjacent brackets 41 form a set. An electric guide rail 62 is fixedly installed at the lower end of the inner cavity of the equipment box 11. A hydraulic rod 63 is fixedly installed on the sliding block of the inner cavity of the electric guide rail 62. A lifting plate 64 is fixedly connected to the output end of the hydraulic rod 63. The lifting plate 64 is slidably connected to the inner cavity of the sleeve 61.

[0101] It should be noted that there is a through groove between two adjacent boxes 61 to facilitate the movement of the lifting plate 64 between the two boxes 61.

[0102] To ensure the strength of the device, the sliding block inside the electric guide rail 62 should fit against the bottom layer of the electric guide rail 62, and the lower end of the electric guide rail 62 should also be made of high-strength material to withstand the squeezing force.

[0103] In this embodiment, when performing a tire compression test on vehicle 13, different support brackets 41 are selected to rise based on the width of vehicle 13 and the position of the tires. At this time, the electric guide rail 62 drives the hydraulic rod 63 to move, causing the lifting plate 64 to move into different housings 61. This ensures that the lifting plate 64 moves into the support bracket 41 below the wheel. Subsequently, the hydraulic rod 63 drives the lifting plate 64 to rise, thereby pushing the structure on the support bracket 41 to apply precise pressure to the wheel. During this process, the extension and retraction of the hydraulic rod 63 is precisely controlled by the electric guide rail 62, ensuring that the lifting plate 64 accurately reaches the predetermined position and applies appropriate force to the wheel. Example

[0104] A new energy vehicle wheel strength testing device and method, applicable to any of the above-mentioned new energy vehicle wheel strength testing devices, comprising:

[0105] S1: Auxiliary positioning: Before the inspection, the vehicle 13 moves above the machine body 10. At this time, the track 42 runs and drives the positioning block 51 to move to a position parallel to the center of the turntable 26, so that the wheels of the vehicle 13 stop on the side of the turntable 26.

[0106] S2: Lifting detection. After the vehicle 13 is moved into position, the lift 12 drives the vehicle 13 to rise. At this time, the positioning block 51 is driven to move by the track 42, moving from the front side of the wheel to the rear side, and the surface condition of the tire is checked by the detection light 53.

[0107] S3: Limiting contact, the lift 12 lifts the vehicle 13 so that the center of the wheel is parallel to the center of the turntable 26. Then the moving part 20 drives the turntable 26 to approach the wheel. Then the slider 32 slides along the inner cavity of the turntable 26 until it is in contact with the outer surface of the wheel. After contact, the turntable 26 rotates, driving the two sets of positioning rods 33 to move to the position above the wheel.

[0108] S4: Strength test. After the positioning rod 33 moves above the wheel, the lifting plate 64 drives the bracket 41 to rise and press the bottom of the wheel. At this time, because of the limitation of the positioning rod 33, the wheel cannot transmit the force to the shock absorption structure, thus performing a precise strength test.

[0109] S5: After the vehicle is dismounted and the test is completed, the drive positioning rod 33 and bracket 41 are reset, and then the vehicle 13 is driven to descend and reset. At this time, the positioning block 51 has moved to the rear of the wheel and can no longer restrict the wheel from rolling. The vehicle 13 can then be driven away from the machine body 10.

[0110] In this embodiment, the wheel should roll during the S2 process so that the detection light 53 can fully view the wheel.

[0111] During the S5 process, if only the front wheels have been tested, the rear wheels of vehicle 13 should be moved to the positioning block 51, and vehicle 13 should be lifted again to test the rear wheels.

[0112] The working principle of this invention is as follows: During inspection, the track 42 is first driven to roll, thereby controlling the position of the positioning block 51 so that the lower end of the positioning block 51 is parallel to the center of the turntable 26. Then, the vehicle 13 is moved below the positioning block 51, and the lift 12 is used to lift the vehicle 13. Subsequently, the positioning block 51 is driven to move, so that the detection light 53 is aimed at the wheel surface for observation, detecting the grooves of the wheel and the condition of the tire. At the same time, during the movement of the positioning block 51, the gear 58 rolls on the surface of the rack 59, thereby driving the rotating rod 56 and the coil 57 to rotate synchronously, driving the wiping plate 54 to slide above the detection light 53, removing dust or dirt from the surface of the detection light 53. Then, the electric push rod 22 drives the moving frame 23 to move, bringing the turntable 26 closer to the wheel. Immediately afterwards, the electric lead screw 34 drives the slider 32 to slide, so that the positioning rod 33 fits against the wheel. The turntable 26 then rotates, moving the positioning rod 33 above the wheel. At this point, the protruding rod 39 contacts the switching button 38, switching the magnetic attraction surface of the electromagnet 37 to positive and negative poles. This causes the magnetic attraction parts of the electromagnet 37 and the limiting block 36 to be of the same pole, allowing the limiting block 36 to extend out of the slider 32 and be fixed in the limiting groove 35. The hydraulic rod 63 then drives the lifting plate 64 to rise, thereby pushing the structure on the bracket 41 to apply precise pressure to the wheel for compression strength testing. After the test is completed, all components are reset, and the positioning block 51 is moved to the rear of the wheel. The vehicle 13 is then lowered and driven out of the machine body 10.

[0113] The technical scope of this invention is not limited to the content described above. Those skilled in the art can make various modifications and variations to the above embodiments without departing from the technical concept of this invention, and all such modifications and variations should fall within the protection scope of this invention.
