Description

Technical Field

[0001] This invention relates to the field of testing device technology, specifically to a strength testing device for automobile wheel hub production based on intelligent sensors. Background Technology

[0002] With the rapid development of the automotive industry, the safety and reliability of automobiles are receiving increasing attention. As one of the key components of a car, the strength of the car wheel hub is directly related to the safety of the car while driving.

[0003] Patent CN210037457U discloses a strength testing device for automobile wheel hub production, comprising a base. Side boxes and side blocks are respectively provided on opposite outer walls of the base. Rotating plates are connected to opposite outer walls of the side boxes and side blocks via bearings. A common fixed platform is provided on the top outer wall of the two rotating plates. A feeding motor is provided on one inner wall of the side box, and the output shaft of the feeding motor is connected to one outer wall of the rotating plate via a key. A rotating mechanism is provided on the top outer wall of the fixed platform, and a force-applying mechanism is provided on the top outer wall of the side blocks. The rotating mechanism includes a mechanism via a shaft. A turntable connected to the top outer wall of a fixed platform is provided, and a clamping platform is provided on the top outer wall of the turntable. This device can load car wheel hubs by rotating the turntable driven by a feeding motor, eliminating the need for manual handling and saving manpower. It is more convenient and faster than screw fixing and can detect the deformation of car wheel hubs in real time. However, during the detection process, it is difficult to accurately detect the pressure on the wheel hub, and therefore it is difficult to know what pressure produces different deformations. Therefore, a strength detection device for car wheel hub production based on intelligent sensors is proposed to solve the above-mentioned problems. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to provide a strength testing device for automobile wheel hub production based on intelligent sensors, which addresses the shortcomings of the prior art.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by the present invention is: a strength testing device for automobile wheel hub production based on intelligent sensors, comprising a base, a housing fixedly connected to the top of the base, a receiver installed on the left side of the housing, a motor fixedly connected to the inner wall of the base, a threaded rod fixedly connected to the output end of the motor, a movable plate threadedly connected to the circumferential surface of the threaded rod, an arc-shaped base fixedly connected to the top of the base, a hollow plate fixedly connected to the bottom of the movable plate, and a support plate fixedly connected to the top of the base. The inner wall of the support plate is connected via... A fixed rod is fixedly connected to a spring, and a placement rod is slidably connected to the circumferential surface of the fixed rod. A fixed plate is fixedly connected to the top of the base, and a sliding rod is slidably connected to the inner wall of the fixed plate via a spring. An inclined plate is fixedly connected to the right side of the sliding rod, and an arc-shaped plate is fixedly connected to the left side of the sliding rod. A cooling mechanism for simulating low-temperature environments for testing is provided at the top of the movable plate. A limiting mechanism for improving testing stability is provided at the top of the base. An H-shaped plate is fixedly connected to the bottom of the movable plate. A pressure sensor is provided on the inner wall of the perforated plate. The receiver and... The pressure sensor is electrically connected and is used to detect the pressure applied during pressure testing. The inner wall of the base is rotatably connected to the circumferential surface of the threaded rod, and the rotation of the threaded rod drives the moving plate to move through the threaded grooves on its surface. The inner wall of the support plate is in contact with the circumferential surface of the placement rod. During operation, the H-shaped plate pushes the inclined plate to move via pulleys, which can apply pressure to the hub, enabling pressure detection of the hub. During detection, the hollow plate will be subjected to the squeezing force of the hub, causing slight deformation, and the force received during deformation will be fed back to the… The pressure sensor can intelligently detect the pressure on the wheel hub and record the pressure when the wheel hub cannot withstand the pressure and is damaged. This allows the wheel hub to maintain a stable posture during the testing process, avoiding displacement or shaking due to pressure application, and helping to ensure the accuracy of pressure detection. When downward pressure is applied to the wheel hub, the slight deformation of the wheel hub will drive the placement rod downward. The downward movement of the placement rod will compress the spring on the surface of the fixing rod, so that the force on the wheel hub during testing is not affected when fixing the wheel hub, allowing the testing to be carried out normally.

[0006] Preferably, the refrigeration mechanism includes a cold air tank, which is fixedly connected to the top of the movable plate. An outlet tank is fixedly connected to the left side of the cold air tank. A rack is fixedly connected to the inner wall of the outer shell. An L-shaped plate is fixedly connected to the bottom of the movable plate. A blade roller is rotatably connected to the inner wall of the L-shaped plate. A gear is fixedly connected to the central shaft of the blade roller. A pressure plate is fixedly connected to the bottom of the H-shaped plate. A chamfered block is fixedly connected to the inner wall of the base. A rotating rod is rotatably connected to the inner wall of the chamfered block. A telescopic rod is fixedly connected to the circumferential surface of the rotating rod. A force-bearing plate is fixedly connected to the circumferential surface of the rotating rod. A lifting column is rotatably connected to the telescopic end of the telescopic rod. A clamping plate is fixedly connected to the top of the lifting column. The inner wall of the outlet tank is fixedly connected to the inner wall of the movable plate. The cold air tank stores cold air for release during low-temperature detection. The blade roller disperses the cold air during its movement. The high speed of cold air diffusion, the front part of the rack meshes with the circumferential surface of the gear, the circumferential surface of the lifting column is slidably connected to the inner wall of the base by a spring, and the pressure plate will contact the force plate during the movement and push the force plate to rotate. It can simulate the real strength, toughness and other indicators of the car wheel hub when the temperature is low in winter, and judge whether it can meet the use requirements in cold regions or low temperature conditions, and prevent safety problems such as wheel hub cracking due to material performance degradation. At the same time, the rotation of the blade roller can accelerate the diffusion of cold air inside the shell, so that the cooling test can be carried out quickly. When the strength test is carried out, the lifting column moves upward and drives the clamping plate to move upward, so that the front part can be limited and fixed during the test, which can ensure that the wheel hub is in a stable position during the test and will not be displaced or shaken due to external forces or its own rotation, which helps to improve the stability of the wheel hub test process.

[0007] Preferably, the limiting mechanism includes a slotted plate, which is fixedly connected to the top of the base. A limiting plate is rotatably connected to the bottom of the slotted plate via a torsion spring. A straight plate is fixedly connected to the bottom of the slotted plate, and a chamfered plate is fixedly connected to the top of the base. A telescopic plate is rotatably connected to the inner wall of the chamfered plate, and a pressing block is fixedly connected to the front of the telescopic plate. The top of the slotted plate and the bottom of the limiting plate are in contact with each other, and the limiting plate will be locked in the inner wall of the slotted plate when upright. The bottom of the straight plate is in contact with the top of the base, and the front of the straight plate is rotatably connected to the telescopic end of the telescopic plate, providing support for the slotted plate. This ensures that the wheel hub is always within the inner wall of the arc-shaped base, preventing the slotted plate from falling due to lack of support after testing, thus failing to limit the wheel hub and causing it to detach. Simultaneously, the straight plate moves upward, driving the slotted plate. At this time, the limiting plate is rotated to the left, releasing the support of the slotted plate and allowing it to fall normally, thus enabling the wheel hub to be removed normally.

[0008] The present invention, by adopting the above technical solution, can bring the following beneficial effects:

[0009] 1. This intelligent sensor-based strength testing device for automotive wheel hub production, through the coordinated operation of a base, housing, receiver, motor, threaded rod, moving plate, arc-shaped base, hollow plate, support plate, fixing rod, placement rod, fixed plate, sliding rod, inclined plate, arc-shaped plate, and pressure sensor, can apply pressure to the wheel hub, enabling pressure testing. During testing, the hollow plate is subjected to the compressive force of the wheel hub, causing slight deformation. This deformation force is then fed back to the pressure sensor, allowing for intelligent detection of the pressure on the wheel hub. The device can also record the pressure at the time of damage if the wheel hub cannot withstand the pressure, thus maintaining a stable posture of the wheel hub during testing and preventing displacement or shaking due to pressure application, contributing to the accuracy of pressure testing. When downward pressure is applied to the wheel hub, the slight deformation causes the placement rod to move downwards. This downward movement of the placement rod compresses the spring on the surface of the fixing rod, ensuring that the force applied to the wheel hub during testing is not affected when fixing the wheel hub, allowing for normal testing.

[0010] 2. This strength testing device for automobile wheel hub production based on intelligent sensors, through the coordinated operation of a cold air tank, an air outlet tank, a rack, an L-shaped plate, a blade roller, and gears, can simulate the actual strength and toughness of automobile wheel hubs under low winter temperatures. It can determine whether the wheel hub can meet the usage requirements in cold regions or low-temperature conditions, preventing safety issues such as wheel hub cracking due to material performance degradation. At the same time, the rotation of the blade roller can accelerate the diffusion of cold air inside the outer shell, enabling rapid cooling testing during strength testing.

[0011] 3. This strength testing device for automobile wheel hub production based on intelligent sensors works in coordination with a pressure plate, chamfer block, rotating rod, telescopic rod, force plate, lifting column, and clamping plate. The lifting column moves upward, causing the clamping plate to move upward, thereby limiting and fixing the front part during testing. This ensures that the wheel hub is in a stable position during testing and will not be displaced or shaken due to external forces or its own rotation, which helps to improve the stability of the wheel hub testing process.

[0012] 4. This strength testing device for automobile wheel hub production based on intelligent sensors, through the coordinated operation of the slot plate, limiting plate, straight plate, chamfering plate, telescopic plate, pressing block, and H-shaped plate, can provide a certain support for the slot plate, thereby ensuring that the wheel hub is always within the inner wall of the arc-shaped base. This prevents the slot plate from falling due to lack of support after the test, which would prevent the wheel hub from being limited and thus causing it to fall off. At the same time, the straight plate moves upward and drives the slot plate. At this time, the limiting plate is rotated to the left, which releases the support of the slot plate, allowing the slot plate to fall normally and the wheel hub to be removed normally.

[0022] 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.

[0023] Please see Figures 1-8One embodiment of the present invention is as follows: a strength testing device for automobile wheel hub production based on intelligent sensors, comprising a base 1, a housing 2 fixedly connected to the top of the base 1, a receiver 3 installed on the left side of the housing 2, a motor 4 fixedly connected to the inner wall of the base 1, a threaded rod 5 fixedly connected to the output end of the motor 4, a movable plate 6 threadedly connected to the circumferential surface of the threaded rod 5, an arc-shaped base platform 7 fixedly connected to the top of the base 1, a hollow plate 8 fixedly connected to the bottom of the movable plate 6, a support plate 9 fixedly connected to the top of the base 1, and a fixing rod fixedly connected to the inner wall of the support plate 9 by a spring. 10. A placement rod 11 is slidably connected to the circumferential surface of the fixed rod 10. A fixed plate 12 is fixedly connected to the top of the base 1. A sliding rod 13 is slidably connected to the inner wall of the fixed plate 12 via a spring. An inclined plate 14 is fixedly connected to the right side of the sliding rod 13. An arc-shaped plate 15 is fixedly connected to the left side of the sliding rod 13. A cooling mechanism 16 for simulating low-temperature environment detection is provided on the top of the moving plate 6. A limiting mechanism 17 for improving detection stability is provided on the top of the base 1. An H-shaped plate 18 is fixedly connected to the bottom of the moving plate 6. A pressure sensor 19 is provided on the inner wall of the hollow plate 8.

[0024] During wheel hub inspection, the center hole of the wheel hub is first clamped onto the placement rod 11 and will fit against the top of the arc-shaped base 7. At this time, the motor 4 starts and drives the threaded rod 5 to rotate. The rotation of the threaded rod 5 drives the moving plate 6 to move downward through the threads on the surface. The downward movement of the moving plate 6 drives the hollow plate 8 to move downward, thereby applying pressure to the wheel hub and enabling pressure testing. During the test, the hollow plate 8 will be subjected to the squeezing force of the wheel hub, causing slight deformation. The force experienced during deformation will then be fed back to the pressure sensor 19, thus intelligently detecting the pressure on the wheel hub and recording the pressure at that time if the wheel hub cannot withstand the pressure and is damaged.

[0025] The receiver 3 is electrically connected to the pressure sensor 19, and the pressure sensor 19 is used to detect the pressure when pressure is applied. The inner wall of the base 1 is rotatably connected to the circumferential surface of the threaded rod 5, and the rotation of the threaded rod 5 drives the moving plate 6 to move through the threaded groove on the surface. The inner wall of the support plate 9 is in contact with the circumferential surface of the placement rod 11. During the operation and movement, the H-shaped plate 18 will push the inclined plate 14 to move through the pulley.

[0026] When pressure is applied to the wheel hub, the moving plate 6 moves downward, causing the H-shaped plate 18 to move downward. When the H-shaped plate 18 moves downward, it contacts the inclined plate 14 through the pulley and generates a squeezing force to push the inclined plate 14 to the left. The movement of the inclined plate 14 causes the sliding rod 13 to move to the left, and the movement of the sliding rod 13 causes the arc plate 15 to move. This keeps the wheel hub in a stable posture during the test, avoiding displacement or shaking due to pressure application, which helps to ensure the accuracy of pressure testing. When downward pressure is applied to the wheel hub, the slight deformation of the wheel hub will cause the placement rod 11 to move downward. The downward movement of the placement rod 11 will compress the spring on the surface of the fixing rod 10, so that when the wheel hub is fixed, the force on the wheel hub during testing is not affected, allowing the test to be carried out normally.

[0027] Overall working principle: The rotation of the threaded rod 5 drives the moving plate 6 downward through the threads on its surface. The downward movement of the moving plate 6 drives the hollow plate 8 downward, thereby applying pressure to the wheel hub and enabling pressure testing. During the test, the hollow plate 8 will be slightly deformed due to the squeezing force of the wheel hub. When the H-shaped plate 18 moves downward, it will contact the inclined plate 14 through the pulley and generate squeezing force to push the inclined plate 14 to the left. The movement of the inclined plate 14 will drive the sliding rod 13 to the left. The downward movement of the placement rod 11 will compress the spring on the surface of the fixing rod 10. Therefore, when fixing the wheel hub, the force on the wheel hub during testing will not be affected, allowing the testing to be carried out normally.

[0028] The refrigeration mechanism 16 includes a cold air tank 161, which is fixedly connected to the top of the movable plate 6. A gas outlet tank 162 is fixedly connected to the left side of the cold air tank 161. A rack 163 is fixedly connected to the inner wall of the outer shell 2. An L-shaped plate 164 is fixedly connected to the bottom of the movable plate 6. A blade roller 165 is rotatably connected to the inner wall of the L-shaped plate 164. A gear 166 is fixedly connected to the central shaft of the blade roller 165. A pressure plate 167 is fixedly connected to the bottom of the H-shaped plate 18. A chamfered block 168 is fixedly connected to the inner wall of the base 1. A rotating rod 169 is rotatably connected to the inner wall of the chamfered block 168. A telescopic rod 1610 is fixedly connected to the circumferential surface of the rotating rod 169.

[0029] When simulating low-temperature environment testing is required, the cold air tank 161 is opened, allowing the cold air inside the cold air tank 161 to be discharged through the air outlet 162. When the cold air is discharged, the moving plate 6 moves, driving the L-shaped plate 164 to move. The movement of the L-shaped plate 164 drives the blade roller 165 to move downward. The downward movement of the blade roller 165 drives the gear 166 to move downward. When the gear 166 moves downward, it meshes with the rack 163 and rotates. The rotation of the gear 166 drives the blade roller 165 to rotate. This can simulate the actual strength, toughness, and other indicators of the car wheel hub when the winter temperature is low, and determine whether it can meet the usage requirements in cold regions or low-temperature conditions. This prevents safety issues such as wheel hub cracking due to material performance degradation. At the same time, the rotation of the blade roller 165 can accelerate the diffusion of cold air inside the outer shell 2, enabling rapid cooling testing.

[0030] A force plate 1611 is fixedly connected to the circumferential surface of the rotating rod 169. A lifting column 1612 is rotatably connected to the telescopic end of the telescopic rod 1610. A clamping plate 1613 is fixedly connected to the top of the lifting column 1612. The inner wall of the air outlet 162 is fixedly connected to the inner wall of the moving plate 6. The cold air tank 161 is used to store cold air for release during low temperature detection. When the blade roller 165 moves, it will blow away the cold air to increase the diffusion speed of the cold air. The front part of the rack 163 meshes with the circumferential surface of the gear 166. The circumferential surface of the lifting column 1612 is slidably connected to the inner wall of the base 1 by a spring. During the movement, the pressure plate 167 will contact the force plate 1611 and push the force plate 1611 to rotate.

[0031] During strength testing, the H-shaped plate 18 moves downward, causing the pressure plate 167 to move downward. The downward movement of the pressure plate 167 brings it into contact with the force plate 1611, applying a compressive force to the force plate 1611 and pushing it to rotate forward. The rotation of the force plate 1611 causes the rotating rod 169 to rotate forward, which in turn causes the telescopic rod 1610 to rotate forward. This, in turn, causes the lifting column 1612 to move upward via the telescopic rod 1610. The upward movement of the lifting column 1612 causes the clamping plate 1613 to move upward, thus limiting and fixing the front part during testing. This ensures that the wheel hub is in a stable position during the testing process and will not shift or shake due to external forces or its own rotation, thereby improving the stability of the wheel hub testing process.

[0032] Overall working principle: The blade roller 165 moves downward, driving the gear 166 to move downward. When the gear 166 moves downward, it meshes with the rack 163 and rotates. The rotation of the gear 166 drives the blade roller 165 to rotate, thus simulating the actual strength, toughness, and other indicators of the car wheel hub under low winter temperatures, and judging whether it can meet the usage requirements in cold regions or low-temperature conditions. At the same time, the rotation of the blade roller 165 can accelerate the diffusion of cold air inside the outer shell 2, enabling rapid cooling detection. The rotation of the rotating rod 169 drives the telescopic rod 1610 to rotate forward, which in turn drives the lifting column 1612 to move upward. The upward movement of the lifting column 1612 drives the clamping plate 1613 to move upward, ensuring that the wheel hub is in a stable position during the detection process.

[0033] Please see Figures 1-8 Based on the above embodiments, in another embodiment of the present invention, the limiting mechanism 17 includes a slot plate 171, the slot plate 171 is fixedly connected to the top of the base 1, the bottom of the slot plate 1613 is rotatably connected to a limiting plate 172 via a torsion spring, the bottom of the slot plate 1613 is fixedly connected to a straight plate 173, the top of the base 1 is fixedly connected to a chamfered plate 174, the inner wall of the chamfered plate 174 is rotatably connected to a telescopic plate 175, and the front of the telescopic plate 175 is fixedly connected to a pressing block 176.

[0034] When the wheel hub is fixed in place, the clamping plate 1613 moves upward, causing the limiting plate 172 to move upward as well. As the limiting plate 172 moves upward, it gradually moves away from the clamping plate 171, allowing the limiting plate 172 to rotate counterclockwise via a torsion spring. When the clamping plate 1613 rises to a certain height, the limiting plate 172 will turn to ninety degrees and lock into the inner wall of the clamping plate 171. When the clamping plate 1613 is fully raised to the required height, the lifting column 1612 will still have a certain gap with the bottom of the base 1, which can provide some support for the clamping plate 1613. This ensures that the wheel hub is always within the inner wall of the arc-shaped base 7, preventing the clamping plate 1613 from falling due to lack of support when the test is completed, thus failing to limit the wheel hub and causing it to fall off.

[0035] The top of the slot plate 171 is in contact with the bottom of the limiting plate 172, and the limiting plate 172 will be stuck in the inner wall of the slot plate 171 when it is erected. The bottom of the straight plate 173 is in contact with the top of the base 1, and the front of the straight plate 173 is rotatably connected to the telescopic end of the telescopic plate 175.

[0036] When the limit switch needs to be engaged, pressing the pressing block 176 causes it to move downwards and rotates the telescopic plate 175. When the telescopic plate 175 rotates, it causes the straight plate 173 to move upwards. The upward movement of the straight plate 173 causes the clamping plate 1613 to move upwards. At this time, the limit plate 172 is turned to the left, which releases the support of the clamping plate 1613, allowing the clamping plate 1613 to fall normally and the wheel hub to be removed normally.

[0037] Overall working principle: When the clamping plate 1613 rises to a certain height, the limiting plate 172 will turn to 90 degrees and lock into the inner wall of the clamping slot plate 171. When the clamping plate 1613 is fully raised to the required height, the lifting column 1612 will still have a certain gap with the bottom of the base 1, which can provide some support for the clamping plate 1613. This ensures that the wheel hub is in the inner wall of the arc-shaped base 7, and the support of the clamping plate 1613 can be released, allowing the clamping plate 1613 to fall normally and the wheel hub to be taken out normally.

Many methods and approaches exist for implementing this technical solution; the above description is merely a preferred embodiment of the invention. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principles of this invention, and these improvements and modifications should also be considered within the scope of protection of this invention. All components not explicitly stated in this embodiment can be implemented using existing technologies.
