Description

Technical Field

[0001] This invention belongs to the field of automotive parts testing technology, specifically relating to a wheel hub positioning device for testing new energy vehicles. Background Technology

[0002] In the automotive industry, a wheel hub typically refers to the rotating component that connects the wheel to the axle. It mainly consists of two parts: the rim and the spokes. As a load-bearing part of the vehicle, the wheel hub must undergo a rigorous testing system after production. Strict testing standards and scientific testing methods are used to ensure the quality of the wheel hub, thereby guaranteeing driving safety.

[0003] Patent publication number CN215865831U discloses a wheel hub positioning device for automobile inspection, including a working platform and a support plate. The support plate is installed on one side of the working platform, and a lifting support seat is installed inside the support plate. A wheel hub slot is formed on the upper surface of the lifting support seat. A fixing seat is fixedly installed on the side of the support plate, and a supporting side plate is installed on the fixing seat. This wheel hub inspection device utilizes a wheel hub pushing guide plate and a support plate to push the wheel hub into the wheel hub slot of the lifting support seat. By raising the lifting support seat, the center of the wheel hub is moved to the same height as the rotation axis and installed on the rotation axis. This eliminates the need for manual lifting, effectively reducing labor intensity. The device's fixing plate can rotate, enabling rotation detection of the wheel hub in both vertical and horizontal states. A single clamping allows for multi-directional detection, effectively improving inspection efficiency.

[0004] However, this device also has shortcomings: while it can improve testing efficiency while reducing labor intensity, it is difficult for the equipment to adaptively adjust to different wheel hub models using mechanical structures, which increases manual intervention to some extent. This can easily lead to non-perpendicular angles between the wheel hub and the testing structure, thus reducing testing accuracy. At the same time, it is difficult to determine whether the wheel hub sidewall is deformed before testing, which can easily cause external factors to interfere with the testing data. Furthermore, it is difficult to know whether the wheel hub and tire are properly installed before testing. If there is an installation deviation between the two, the obtained testing data can easily mislead the staff in the subsequent adjustment direction of the wheel hub. Summary of the Invention

[0005] The purpose of this invention is to provide a wheel hub positioning device for testing new energy vehicles, in order to solve the problem mentioned in the background art that when positioning different models of wheel hubs, the equipment is difficult to complete the corresponding adjustment by mechanical structure, which increases the need for manual intervention to a certain extent, and thus easily causes non-perpendicular angular displacement between the wheel hub and the testing structure.

[0006] To achieve the above objectives, the present invention provides a wheel hub positioning device for testing new energy vehicles, comprising: a base, wherein a direct-push device for detecting whether the outer wall of the wheel hub is deformed is disposed inside the base, and an error-prevention device for detecting whether the surface of the wheel hub is covered with dirt is disposed around the direct-push device; two limiting mechanisms are equidistantly disposed on the top of the base; a sliding frame is disposed on the back of the base, and a T-shaped frame is slidably installed inside the sliding frame; a detection mechanism is disposed at the bottom of the T-shaped frame; and a dual-head motor is disposed at the bottom of the inner wall of the base, wherein the two output ends of the dual-head motor are symmetrically and fixedly mounted. Two drive rods are provided, each with a movably mounted lifting mechanism at its spiral groove. Workers roll the wheel hub between the two ramps via the front ramp of the base. Then, the dual-head motor starts, and its output rotation drives the drive rods to rotate. As the drive rods rotate, their non-self-locking spiral grooves on their outer walls guide the internal locking blocks of the lifting mechanism, causing it to generate a horizontal force. An elastic telescopic rod is slidably mounted inside the output end of the lifting mechanism. A limit plate is fixedly mounted on the side wall of the telescopic end of the elastic telescopic rod. The lifting mechanism drives the elastic telescopic rod to move synchronously, allowing for elastic extension and contraction. The lever drives the limiting plate to slide horizontally along the top of the base. The telescopic ends of the limiting plates on both sides simultaneously drive the limiting rod and limiting cylinder closer together. If there is a height difference between the limiting rod and the limiting cylinder and the center of the wheel hub, the lifting mechanism is activated, driving the elastic telescopic rod upwards. A limiting rod is fixedly installed on the right side of the limiting plate's telescopic end, away from the lifting mechanism, and a limiting cylinder is fixedly installed on the left side of the limiting plate's telescopic end, away from the lifting mechanism. A fan is fixedly installed on the side of the lifting mechanism closest to the limiting plate, and the elastic telescopic rod causes the telescopic end of the limiting plate to rise. At this time, the limiting rod and the limiting cylinder... The cylinder is fully adjusted in height, and the limiting rod and limiting cylinder are located at the center of the wheel hub, with the limiting rod inserted into the limiting cylinder. At this time, the limiting plate, limiting rod, and limiting cylinder complete the vertical limiting of the wheel hub. Then, the sliding frame is activated, and the sliding frame drives the T-shaped frame to descend. The T-shaped frame drives the detection mechanism to descend and contact the outer wall of the top of the wheel hub. The detection mechanism drives the wheel hub to rotate between the two limiting mechanisms, thereby completing the detection work. At the same time, the lifting mechanism drives the fan to move synchronously. When the fan moves towards the wheel hub, it blows the vertical side wall of the wheel hub, completing the cleaning work of the wheel hub before contacting the limiting plate.

[0007] In one possible implementation, a telescopic plate is slidably mounted on the front edge of the sliding frame, and the telescopic plate has a built-in pressure sensor. Several equidistant, rotatable wheels are mounted inside the vertical groove at the telescopic end of the telescopic plate. An inclined plate is hinged to the front of the telescopic plate via a torsion spring. A baffle is hinged to the end of the inclined plate near the T-shaped frame. The base has a hollow design both inside and on the front. The limiting mechanism has a rotating design inside and performs limiting during dynamic balancing testing of the wheel hub. The detection mechanism can drive the wheel hub to rotate to complete the detection. The dual-head motor has two... Each output end can rotate in both directions. When the lifting mechanism moves horizontally, it drives the telescopic plate to slide synchronously along the side wall of the sliding frame. The telescopic end of the telescopic plate drives the rotating wheel to move synchronously. The circumferential surface of the rotating wheel is always in close contact with the outer side wall of the T-shaped frame through the spring force. If the T-shaped frame deviates from its track when it descends, the pressure sensor inside the telescopic plate can issue an alarm message in time. At the same time, the telescopic plate drives the inclined plate to move synchronously. The inclined plate is limited by the baffle, which causes its own hinge shaft to start rotating. The inclined plate moves in an arc trajectory. At this time, the inclined plate pushes the baffle to move forward, thereby removing the obstruction to the detection mechanism.

[0008] In one possible implementation, the transmission rod extends through the base from the end away from the dual-head motor, and the outer wall of the transmission rod has a non-self-locking spiral groove. The bottom of the limiting plate is slidably installed at the top edge of the base, and the limiting plate is telescopic. The inside of the limiting cylinder is located on the movement trajectory of the limiting rod. The telescopic plate is elastic, and the telescopic end of the telescopic plate has a vertical groove. The front side wall of the T-shaped frame is located on the movement trajectory of the rotating wheel, and the top of the baffle contacts the bottom of the detection mechanism.

[0009] In one possible implementation, the direct-push device includes a gear that is internally and fixedly mounted on the outer wall of a transmission rod. A Z-shaped toothed plate is slidably mounted on the bottom of the inner wall of the base. When the transmission rod rotates, it drives the gear to revolve. The gear causes the Z-shaped toothed plate, which meshes with itself, to generate a horizontal force. When the Z-shaped toothed plate slides horizontally forward along the bottom of the inner wall of the base, it contacts and abuts against the upper back of the flipping plate. The Z-shaped toothed plate meshes with the gear. A crossbar is fixedly mounted inside one end of the front of the base. A flipping plate is rotatably mounted on the outer wall of the crossbar through a torsion spring.

[0010] In one possible implementation, the top of the flip plate is elastically telescopic, the top arc surface of one end of the front of the base is located on the movement trajectory of the telescopic end of the flip plate, and the back of the flip plate is located on the top movement trajectory of one end of the front of the Z-shaped toothed plate. One end of the back of the Z-shaped toothed plate moves through the back of the base. At this time, the flip plate, which is limited by the crossbar, generates a rotational force, that is, the flip plate rotates along the outer wall of the crossbar in an arc trajectory. After the telescopic end of the flip plate disengages from the inner part of the front of the base, it extends outward by the spring force. At this time, the flip plate is in an inclined posture.

[0011] In one possible implementation, an L-shaped plate is fixedly installed at the top edge of one end of the back of the Z-shaped toothed plate, and a vertical plate is slidably installed at the top edge of the base via a spring. When the Z-shaped toothed plate moves forward horizontally, it drives the L-shaped plate to move synchronously. When the L-shaped plate moves horizontally, it contacts and abuts against the back of the vertical plate. At this time, the vertical plate generates a sliding force and slides along the top of the base. The back of the vertical plate is located on the top movement trajectory of the L-shaped plate. Several arc-shaped plates are equidistantly and slidably installed on the front of the vertical plate via springs. When the arc-shaped plates move horizontally, they contact the vertical outer wall of the wheel hub. The vertical plate drives the slidably installed arc-shaped plates to move synchronously. The arc-shaped plates are guided by the arc surface at one end of the front and, with the help of the spring force, can adaptively conform to the side wall of wheel hubs of different widths during horizontal movement.

[0012] In one possible implementation, the error prevention device includes a U-shaped plate, the front of which is fixedly mounted on the back of a sliding frame, an adhesive plate fixedly mounted on the back of a vertical plate, a scraper rotatably mounted at the center of the adhesive plate, a rotating rod fixedly mounted through the back of the scraper, the sliding frame limiting the U-shaped plate, and when the vertical plate moves horizontally, it drives the adhesive plate to move synchronously, the adhesive plate drives the rotatably mounted scraper to move synchronously, and the scraper drives the rotating rod to move synchronously.

[0013] In one possible implementation, a non-self-locking spiral groove is provided on the outer wall of one end of the back of the rotating rod. The spiral groove of the rotating rod is movably installed inside the U-shaped plate through the outer wall. When the rotating rod moves forward, the non-self-locking spiral groove on its outer wall is guided by the built-in locking block of the U-shaped plate, causing the rotating rod to generate a rotational force and start to rotate. The rotating rod drives the scraper to rotate and scrape inside the adhesive plate.

[0014] In one possible implementation, an elliptical block is fixedly installed through and on the outer wall of one end of the rotating rod. A U-shaped sliding plate is slidably installed on the outer side wall of the vertical plate via a spring. An abutment wheel is rotatably installed inside the U-shaped sliding plate, and the circumferential surface of the abutment wheel contacts the outer wall of the elliptical block. A laser is installed inside one end of the front of the U-shaped sliding plate. The rotating rod drives the elliptical block to rotate. When the elliptical block rotates, it releases the limit on the abutment wheel. At this time, the U-shaped sliding plate slides down along the outer side wall of the vertical plate by the spring force. The U-shaped sliding plate drives the abutment wheel to move synchronously with the laser. The laser relies on the laser scanning hub to check whether there is an angular deviation perpendicular to the axis of rotation. Then, the elliptical block pushes the abutment wheel to reset, and the abutment wheel causes the U-shaped sliding plate to reset. This process is repeated, and the U-shaped sliding plate drives the laser to perform reciprocating vertical motion. The laser performs dynamic laser scanning.

[0015] Compared with existing technologies, the beneficial effects of this invention are that, through the cooperation of a dual-head motor, transmission rod, lifting mechanism, elastic telescopic rod, limiting plate, limiting rod, limiting cylinder, fan, telescopic plate, rotating wheel, inclined plate, and baffle, and through the mechanical mechanisms such as the lifting mechanism and limiting plate, the device can adapt to hubs of different sizes and widths, always completing the inspection work in a vertical limiting posture. That is, no excessive manual intervention is required before inspection, optimizing the process and improving efficiency. At the same time, the fan effectively prevents the hub from being worn due to the adhesion of foreign objects during rotation inspection, preventing increased losses. Through the rotating wheel and pressure sensor, it is easy for the staff to know in real time whether the inspection mechanism is vertically lifting, avoiding the inspection mechanism from offset contact with the top of the hub due to the T-shaped frame derailment, which would cause positioning deviation and reduce the accuracy of the inspection results.

[0016] By employing a direct-push device, and through the coordination of a transmission rod, gears, Z-shaped toothed plates, crossbars, a tilting plate, an L-shaped plate, a vertical plate, and an arc-shaped plate, the tilting plate's rotation and tilting allow it to unload force on the wheel hub if it rolls forward due to operator error when the limiting plate fails to limit its movement. This reduces the impact force generated during wheel hub rolling and prevents injury. Simultaneously, the tilting plate delineates the working area during wheel hub inspection, ensuring operators can maintain a safe distance. The horizontal movement of the arc-shaped plate further ensures the wheel hub remains vertically positioned while allowing observation of whether the wheel hub's two ends are in contact with the outer wall of the arc-shaped plate. If a gap exists, the wheel hub may deform, necessitating replacement.

[0017] By incorporating an error-prevention device, a combination of a vertical plate, a U-shaped plate, an adhesive plate, a scraper, a rotating rod, an elliptical block, a U-shaped sliding plate, a contact wheel, and a laser, the rotating scraper ensures that the interior of the adhesive plate is clean before the inspection begins. When the wheel hub rotates, if it flings off dirt from its surface, the adhesive plate will adhere to it; otherwise, it remains clean. This allows staff to determine the accuracy of the inspection data based on different scenarios. The laser detects any misalignment between the wheel hub and the tire, facilitating timely positioning adjustments and preventing erroneous data from misleading staff and negatively impacting subsequent vehicle operation.

[0020] The specific embodiments of the present invention will now be described in detail with reference to the accompanying drawings, but it should be understood that the scope of protection of the present invention is not limited to the specific embodiments.

[0021] like Figures 1-8 As shown, one embodiment of the present invention is: a wheel hub positioning device for testing new energy vehicles, comprising: a base 1, a direct-push device 18 for detecting whether the outer wall of the wheel hub is deformed is provided inside the base 1, an error-prevention device 19 for detecting whether the surface of the wheel hub is covered with dirt is provided around the direct-push device 18, two limiting mechanisms 2 are equidistantly arranged on the top of the base 1, a sliding frame 3 is provided on the back of the base 1, a T-shaped frame 4 is slidably installed inside the sliding frame 3, a detection mechanism 5 is provided at the bottom of the T-shaped frame 4, and a double-headed motor 6 is provided at the bottom of the inner wall of the base 1. The machine 6 has two symmetrical and fixedly installed transmission rods 7 at its two output ends. Lifting mechanisms 8 are movably installed at the spiral grooves of the two transmission rods 7. Elastic telescopic rods 9 are slidably installed inside the output end of the lifting mechanism 8. Limiting plates 10 are fixedly installed on the side wall of the telescopic end of the elastic telescopic rods 9. A limiting rod 11 is fixedly installed on the side of the telescopic end of the right limiting plate 10 away from the lifting mechanism 8. A limiting cylinder 12 is fixedly installed on the side of the telescopic end of the left limiting plate 10 away from the lifting mechanism 8. A fan 13 is fixedly installed on the side of the lifting mechanism 8 near the limiting plate 10.

[0022] A telescopic plate 14 is slidably installed on the front edge of the sliding frame 3, and the telescopic plate 14 has a built-in pressure sensor. Several rotating wheels 15 are equidistantly and rotatably installed inside the vertical groove of the telescopic end of the telescopic plate 14. An inclined plate 16 is hinged to the front of the telescopic plate 14 by a torsion spring. A baffle 17 is hinged to the end of the inclined plate 16 near the T-shaped frame 4. The interior and front of the base 1 are hollowed out. The interior of the limiting mechanism 2 is a rotating design. The limiting mechanism 2 limits the wheel hub during dynamic balancing testing. The testing mechanism 5 can drive the wheel hub to rotate to complete the testing. Both output ends of the dual-head motor 6 can rotate in both directions.

[0023] The transmission rod 7 extends through the base 1 at one end away from the dual-head motor 6, and the outer wall of the transmission rod 7 has a non-self-locking spiral groove. The bottom of the limiting plate 10 is slidably installed at the top edge of the base 1, and the limiting plate 10 is telescopic. The inside of the limiting cylinder 12 is located on the movement trajectory of the limiting rod 11. The telescopic plate 14 is elastic, and the telescopic end of the telescopic plate 14 has a vertical groove. The front side wall of the T-shaped frame 4 is located on the movement trajectory of the rotating wheel 15. The top of the baffle 17 is in contact with the bottom of the detection mechanism 5.

[0024] By incorporating mechanical mechanisms such as the lifting mechanism 8 and the limiting plate 10, the equipment can adapt to wheel hubs of different sizes and widths, always maintaining a vertically limited posture to complete the inspection work. This eliminates the need for excessive manual intervention before inspection, optimizing the process and improving efficiency. Simultaneously, the fan 13 effectively prevents wear on the wheel hub due to foreign objects adhering during rotational inspection, thus preventing increased losses. The rotating wheel 15 and pressure sensor allow staff to monitor in real time whether the inspection mechanism 5 is vertically lifting, preventing misalignment between the inspection mechanism 5 and the top of the wheel hub due to the T-shaped frame 4 derailing, which could lead to positioning deviations and reduced accuracy of the inspection results.

[0025] In use, the operator rolls the wheel hub between the two ramps on the front of the base 1. Then, the dual-head motor 6 starts. When the output end of the dual-head motor 6 rotates, it drives the transmission rod 7 to rotate. When the transmission rod 7 rotates, it guides the built-in locking block of the lifting mechanism 8 through the non-self-locking spiral groove on its outer wall, causing the lifting mechanism 8 to generate a horizontal force. The lifting mechanism 8 drives the elastic telescopic rod 9 to move synchronously. The elastic telescopic rod 9 drives the limiting plate 10 to slide horizontally along the top of the base 1. The telescopic ends of the limiting plates 10 on the left and right sides synchronously drive... When the movable limiting rod 11 and the limiting cylinder 12 approach each other, if there is a height difference between the limiting rod 11 and the limiting cylinder 12 and the center of the wheel hub, the lifting mechanism 8 is activated. The lifting mechanism 8 drives the elastic telescopic rod 9 to rise, and the elastic telescopic rod 9 causes the telescopic end of the limiting plate 10 to rise. At this time, the limiting rod 11 and the limiting cylinder 12 complete the height adjustment. At the same time, the limiting rod 11 and the limiting cylinder 12 are located at the center of the wheel hub, and the limiting rod 11 is inserted into the limiting cylinder 12. At this time, the limiting plate 10, the limiting rod 11, and the limiting cylinder 12 complete the vertical limiting of the wheel hub. Then, the sliding frame 3 is activated, driving the T-shaped frame 4 to descend. The T-shaped frame 4 drives the detection mechanism 5 to descend and contact the outer wall of the top of the wheel hub. The detection mechanism 5 drives the wheel hub to rotate between the two limiting mechanisms 2, thus completing the detection work. At the same time, the lifting mechanism 8 drives the fan 13 to move synchronously. When the fan 13 moves towards the wheel hub, it blows the vertical side wall of the wheel hub, completing the cleaning work of the wheel hub before contacting the limiting plate 10. When the lifting mechanism 8 moves horizontally, it drives the telescopic plate 14 to slide synchronously along the side wall of the sliding frame 3. When the telescopic plate 14 extends, the telescopic end drives the rotating wheel 15 to move synchronously. The circumferential surface of the rotating wheel 15 is always in close contact with the outer side wall of the T-shaped frame 4 by the spring force. If the T-shaped frame 4 deviates from its track when it descends, the pressure sensor inside the telescopic plate 14 can issue an alarm message in time. At the same time, the telescopic plate 14 drives the inclined plate 16 to move synchronously. The inclined plate 16 is limited by the baffle 17, which causes its own hinge shaft to start rotating. The inclined plate 16 moves in an arc trajectory. At this time, the inclined plate 16 pushes the baffle 17 forward, thereby removing the obstruction to the detection mechanism 5.

[0026] According to the above embodiments, the mechanical mechanisms such as the lifting mechanism 8 and the limiting plate 10 enable the equipment to adapt to hubs of different sizes and widths, always completing the inspection work in a vertically limited posture. This means that minimal manual intervention is required before inspection, optimizing the process and improving efficiency. At the same time, the fan 13 effectively prevents wear on the hub due to foreign objects adhering during rotational inspection, preventing increased losses. The rotating wheel 15 and pressure sensor allow staff to monitor in real time whether the inspection mechanism 5 is vertically lifting, preventing the inspection mechanism 5 from derailing due to the T-shaped frame 4, which could cause misalignment between the inspection mechanism 5 and the top of the hub, resulting in positioning deviations and reduced accuracy of the inspection results.

[0027] like Figures 1-8As shown, based on the above embodiments, another embodiment of the present invention further includes a direct push device 18; The direct push device 18 includes a gear 181, which is internally penetrated and fixedly installed on the outer wall of the transmission rod 7. A Z-shaped toothed plate 182 is slidably installed on the bottom of the inner wall of the base 1, and the Z-shaped toothed plate 182 meshes with the gear 181. A crossbar 183 is fixedly installed inside one end of the front of the base 1, and a flip plate 184 is rotatably installed on the outer wall of the crossbar 183 through a torsion spring.

[0028] The top of the flip plate 184 is designed to be elastic and telescopic. The top arc surface of one end of the front of the base 1 is located on the movement trajectory of the telescopic end of the flip plate 184. The back of the flip plate 184 is located on the top movement trajectory of one end of the front of the Z-shaped toothed plate 182. One end of the back of the Z-shaped toothed plate 182 moves through the back of the base 1. The torsion spring of the flip plate 184 has buffer damping and can absorb the rolling kinetic energy of the wheel hub.

[0029] An L-shaped plate 185 is fixedly installed at the top edge of one end of the back of the Z-shaped toothed plate 182. A vertical plate 186 is slidably installed at the top edge of the base 1 via a spring. The back of the vertical plate 186 is located on the top movement trajectory of the L-shaped plate 185. Several arc-shaped plates 187 are equidistantly and slidably installed on the front of the vertical plate 186 via springs. When the arc-shaped plates 187 move horizontally, they come into contact with the vertical outer wall of the hub.

[0030] By rotating and tilting the tilting plate 184, if the wheel hub rolls forward due to operator error when the limiting plate 10 is not limiting it, the tilting plate 184 can unload the rolling wheel hub, reducing the impact force generated during the wheel hub's rolling and preventing personnel injury. At the same time, the tilting plate 184 delineates the working area during wheel hub inspection, preventing operators from having difficulty controlling the safety range. The horizontal movement of the arc-angle plate 187 further ensures that the wheel hub is always positioned at a vertical angle, while allowing observation of whether there is a gap between the outer peripheral wall of the wheel hub and the arc-angle plate 187. If there is a gap, the wheel hub may be locally deformed, thus requiring wheel hub replacement.

[0031] In use, when the transmission rod 7 rotates, it drives the gear 181 to revolve. The gear 181 causes the Z-shaped toothed plate 182, which meshes with itself, to generate a horizontal force. When the Z-shaped toothed plate 182 slides horizontally forward along the bottom of the inner wall of the base 1, it will contact and abut against the upper back of the flip plate 184. At this time, the flip plate 184, which is limited by the crossbar 183, generates a rotational force, that is, the flip plate 184 rotates along the outer wall of the crossbar 183 in an arc-shaped trajectory. After the telescopic end of the flip plate 184 disengages from the inner part of the front end of the base 1 and abuts, it is released by the spring force. Extending outwards, the flip plate 184 is tilted at this time; when the Z-shaped toothed plate 182 moves forward horizontally, it drives the L-shaped plate 185 to move synchronously. When the L-shaped plate 185 moves horizontally, it contacts and abuts the back of the vertical plate 186. At this time, the vertical plate 186 generates a sliding force and slides along the top of the base 1. The vertical plate 186 drives the sliding arc-shaped plate 187 to move synchronously. The arc-shaped plate 187 is guided by the arc surface at one end of the front side, and with the help of the spring force, it can adaptively fit the side wall of the wheel hub of different widths during the horizontal movement.

[0032] According to the above embodiment, by rotating and tilting the flip plate 184, if the wheel hub rolls forward due to the operator's hand error when the limiting plate 10 does not limit the wheel hub, the flip plate 184 can unload the rolling wheel hub, reduce the impact force generated when the wheel hub rolls, and avoid personnel injury. At the same time, the flip plate 184 delineates the working area during wheel hub inspection, preventing the operator from having difficulty controlling the safety range. The horizontal movement of the arc plate 187 can further ensure that the wheel hub is always positioned at a vertical angle, while observing whether the two ends of the wheel hub are in contact with the outer wall of the arc plate 187. If there is a gap between the two, the wheel hub may be deformed, and the wheel hub needs to be replaced.

[0033] like Figures 1-8 As shown, based on the above embodiments, another embodiment of the present invention further includes an error prevention device 19; The error prevention device 19 includes a U-shaped plate 191, the front of which is fixedly installed on the back of the sliding frame 3. An adhesive plate 192 is fixedly installed on the back of the vertical plate 186. A scraper 193 is rotatably installed at the center of the adhesive plate 192. A rotating rod 194 is fixedly installed through the back of the scraper 193.

[0034] A non-self-locking spiral groove is provided on the outer wall of one end of the back of the rotating rod 194. The spiral groove of the rotating rod 194 passes through the outer wall and is movably installed inside the U-shaped plate 191.

[0035] An elliptical block 195 is fixedly installed through the outer wall of one end of the front of the rotating rod 194. A U-shaped sliding plate 196 is slidably installed on the outer side wall of the vertical plate 186 via a spring. An abutting wheel 197 is rotatably installed inside the U-shaped sliding plate 196. The circumferential surface of the abutting wheel 197 contacts the outer wall of the elliptical block 195. A laser 198 is installed inside one end of the front of the U-shaped sliding plate 196. The laser 198 scans the hub to see if there is an angular deviation perpendicular to the axis of rotation when the hub rotates.

[0036] The rotating scraper 193 ensures that the interior of the adhesion plate 192 is clean before the inspection begins. If the wheel hub shakes off dirt carried on its surface during rotation, the adhesion plate 192 will adhere to it. If no dirt is carried, the adhesion plate 192 remains clean. This allows staff to determine the accuracy of the inspection data based on different situations. The laser 198 detects any misalignment between the wheel hub and tire, facilitating timely positioning adjustments and preventing erroneous data from misleading staff and hindering subsequent vehicle operation.

[0037] In use, the sliding frame 3 limits the U-shaped plate 191. When the vertical plate 186 moves horizontally, it drives the adhesive plate 192 to move synchronously. The adhesive plate 192 drives the rotating scraper 193 to move synchronously. The scraper 193 drives the rotating rod 194 to move synchronously. When the rotating rod 194 moves forward, the non-self-locking spiral groove on its outer wall is guided by the internal locking block of the U-shaped plate 191, causing the rotating rod 194 to generate rotational force and start rotating. The rotating rod 194 drives the scraper 193 to rotate and scrape inside the adhesive plate 192. 4. The elliptical block 195 is rotated. When the elliptical block 195 rotates, it releases the limit on the contact wheel 197. At this time, the U-shaped slide plate 196 slides down along the outer side wall of the vertical plate 186 by the spring force. The U-shaped slide plate 196 drives the contact wheel 197 to move synchronously with the laser 198. Then the elliptical block 195 pushes the contact wheel 197 to reset. The contact wheel 197 causes the U-shaped slide plate 196 to reset. This process is repeated. The U-shaped slide plate 196 drives the laser 198 to perform reciprocating vertical motion. The laser 198 performs dynamic laser scanning.

[0038] According to the above embodiment, the rotating scraper 193 ensures that the interior of the adhesion plate 192 is clean before the inspection begins. Therefore, if the wheel hub shakes off dirt carried on its surface during rotation, the adhesion plate 192 will adhere to it. If no dirt is carried, the adhesion plate 192 remains clean. This allows the operator to determine the accuracy of the inspection data based on different situations. The laser 198 detects whether there is misalignment between the wheel hub and the tire, facilitating timely positioning adjustments by the operator and preventing erroneous inspection data from misleading the operator's adjustment direction, which would be detrimental to subsequent vehicle driving.
