[0004] The technical problem to be solved by the present invention is to provide a strength detection device for automobile wheel hub production based on an intelligent sensor in view of the above-mentioned deficiencies in the prior art.

[0005] In order to solve the above technical problems, the technical solution adopted by the present invention is: a strength detection device for automobile wheel hub production based on an intelligent sensor, comprising a base, the top of the base is fixedly connected to a shell, a receiver is installed on the left side of the shell, the inner wall of the base is fixedly connected to a motor, the output end of the motor is fixedly connected to a threaded rod, the circumferential surface of the threaded rod is threadedly connected to a movable plate, the top of the base is fixedly connected to an arc-shaped bottom platform, the bottom of the movable plate is fixedly connected to a hollow plate, the top of the base is fixedly connected to a support plate, and the inner wall of the support plate is fixedly connected to the bottom of the movable plate. The spring is fixedly connected to the fixed rod, the circumferential surface of the fixed rod is slidably connected to the placing rod, the top of the base is fixedly connected to the fixed plate, the inner wall of the fixed plate is slidably connected to the sliding rod through the spring, the right side of the sliding rod is fixedly connected to the inclined plate, the left side of the sliding rod is fixedly connected to the arc plate, the top of the movable plate is provided with a refrigeration mechanism for simulating a low temperature environment for detection, the top of the base is provided with a limit mechanism to improve the detection stability, the bottom of the movable plate is fixedly connected to an H-shaped plate, the inner wall of the hollow plate is provided with a pressure sensor, the receiver and The pressure sensor is electrically connected, and the pressure sensor is used to detect the pressure when pressure is applied. The inner wall of the base is rotatably connected to the circumferential surface of the threaded rod, and the threaded rod rotates through the threaded groove opened on the surface to drive the movable plate to move. The inner wall of the support plate is in contact with the circumferential surface of the placement rod. The H-shaped plate pushes the inclined plate to move through the pulley during the movement process, which can apply pressure to the wheel hub, so that the wheel hub can be pressure tested. During the test, the hollow plate will be squeezed by the wheel hub to cause a slight deformation, and the force received during the deformation will be fed back to the The pressure sensor can intelligently detect the pressure on the wheel hub, and record the pressure at that time when the wheel hub cannot withstand the pressure and is damaged, so that the wheel hub can maintain a stable posture during the detection process, avoiding displacement or shaking due to pressure application, which helps to ensure the accuracy of pressure detection. When downward pressure is applied to the wheel hub, the wheel hub will cause a slight deformation to drive the placement rod downward. The downward movement of the placement rod will squeeze the spring compression on the surface of the fixing rod, so that when the wheel hub is fixed, it will not affect the force applied to the wheel hub during detection, so that normal detection can be carried out.

[0006] The top of the lifting column is fixedly connected to the card plate, and the inner wall of the air outlet tank is fixedly connected to the inner wall of the movable plate.

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 performing strength testing, the lifting column moves upward to drive the card plate to move upward, so that the front 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 force or its own rotation, which helps to improve the stability of the wheel hub detection process.

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

[0009] 1. This intelligent sensor-based strength testing device for automobile wheel hub production, through the coordinated operation of a base, housing, receiver, motor, threaded rod, movable plate, curved base, hollow plate, support plate, fixed rod, placement rod, fixed plate, sliding rod, inclined plate, curved plate, and pressure sensor, can apply pressure to the wheel hub, enabling pressure testing of the wheel hub. During testing, the hollow plate is slightly deformed by the squeezing force of the wheel hub, and the force exerted during deformation is fed back to the pressure sensor, thereby intelligently detecting the pressure exerted on the wheel hub. The pressure at that time can be recorded when the wheel hub cannot withstand the pressure and is damaged, thereby maintaining a stable posture of the wheel hub during testing, avoiding displacement or shaking due to the applied pressure, and helping to ensure the accuracy of the pressure test. When downward pressure is applied to the wheel hub, the slight deformation of the wheel hub drives the placement rod downward, which compresses the spring on the surface of the placement rod. Therefore, when the wheel hub is fixed, the force exerted on the wheel hub during testing is not affected, allowing normal testing.

[0010] 2. The strength detection device for automobile wheel hub production based on intelligent sensors can simulate the real strength, toughness and other indicators of automobile wheel hubs when the temperature is low in winter through the coordinated operation between the cold air tank, air outlet tank, rack, L-shaped plate, blade roller and gear, and judge whether it can meet the use requirements in cold areas or low temperature conditions, and prevent safety problems such as wheel hub rupture caused by the degradation of material properties. At the same time, the rotation of the blade roller can accelerate the diffusion of cold air inside the shell, so that cooling detection can be carried out quickly during strength testing.

[0011] 3. This intelligent sensor-based strength testing device for automobile wheel hub production works in coordination among the pressure plate, chamfering block, rotating rod, telescopic rod, force plate, lifting column, and clamping plate. The lifting column moves upward, driving the clamping plate upward, so that the front can be limited and fixed during testing. This can ensure that the wheel hub is in a stable position during the testing process 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. The strength detection device for automobile wheel hub production based on intelligent sensors can provide certain support to the card plate through the coordinated operation of the card slot plate, limit plate, straight plate, chamfered plate, telescopic plate, pressing block, and H-shaped plate, thereby ensuring that the wheel hub is definitely located in the inner wall of the arc-shaped base, avoiding the problem that the card plate has no support and falls when the detection is completed, and the wheel hub cannot be limited and falls off.

DETAILED DESCRIPTION

[0022] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0023] See also Figures 1-8One embodiment of the present invention is: a strength detection device for automobile wheel hub production based on an intelligent sensor, 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 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 fixed rod fixedly connected to the inner wall of the support plate 9 via a spring. 10. The circumferential surface of the fixed rod 10 is slidably connected to the placing rod 11, the top of the base 1 is fixedly connected to the fixed plate 12, the inner wall of the fixed plate 12 is slidably connected to the sliding rod 13 through a spring, the right side of the sliding rod 13 is fixedly connected to the inclined plate 14, the left side of the sliding rod 13 is fixedly connected to the arc plate 15, the top of the movable plate 6 is provided with a refrigeration mechanism 16 for simulating a low-temperature environment for detection, the top of the base 1 is provided with a limiting mechanism 17 for improving the detection stability, the bottom of the movable plate 6 is fixedly connected to an H-shaped plate 18, and the inner wall of the hollow plate 8 is provided with a pressure sensor 19.

[0024] When performing wheel hub inspection, the center hole of the wheel hub is now clamped on the placement rod 11 and will fit with the top of the arc-shaped base 7. At this time, the motor 4 is started and will drive the threaded rod 5 to rotate. The threaded rod 5 rotates and drives the movable plate 6 to move downward through the threads opened on the surface. The movable plate 6 moves downward and drives the hollow plate 8 to move downward, so that pressure can be applied to the wheel hub, so that the wheel hub can be pressure-tested. During the inspection, the hollow plate 8 will be squeezed by the wheel hub, causing it to deform slightly, and the force it receives during the deformation will be fed back to the pressure sensor 19, so that the pressure on the wheel hub can be intelligently detected, and the pressure at that time can be recorded when 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 threaded rod 5 rotates through the threaded groove opened on the surface to drive the movable plate 6 to move. 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 movable plate 6 moves downward, driving the H-shaped plate 18 to move downward. When the H-shaped plate 18 moves downward, it will contact the inclined plate 14 through the pulley, and generate an extrusion force to push the inclined plate 14 to move to the left. The movement of the inclined plate 14 drives the sliding rod 13 to move to the left, and the movement of the sliding rod 13 drives the arc plate 15 to move, so that the wheel hub maintains a stable posture during the detection process, avoiding displacement or shaking due to pressure application, which helps to ensure the accuracy of pressure detection. When downward pressure is applied to the wheel hub, the wheel hub will drive the placement rod 11 to move downward when it is slightly deformed. The downward movement of the placement rod 11 will squeeze the spring compression on the surface of the fixing rod 10, so that when the wheel hub is fixed, it will not affect the force applied to the wheel hub during detection, so that normal detection can be carried out.

[0027] The overall working principle: the threaded rod 5 rotates through the thread opened on the surface to drive the movable plate 6 to move downward, and the downward movement of the movable plate 6 drives the hollow plate 8 to move downward, thereby applying pressure to the wheel hub, so that the wheel hub can be pressure tested, and during the test, the hollow plate 8 will be squeezed by the extrusion force of the wheel hub, causing slight deformation. When the H-shaped plate 18 moves downward, it will contact the inclined plate 14 through the pulley, and generate an extrusion force to push the inclined plate 14 to move to the left. The movement of the inclined plate 14 drives the sliding rod 13 to move to the left, and the downward movement of the placement rod 11 will squeeze the spring compression on the surface of the fixed rod 10, so that when the wheel hub is fixed, it will not affect the force applied to the wheel hub during detection, so that normal detection can be carried out.

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

[0029] When it is necessary to simulate low-temperature environment testing, open the cold air tank 161 so that the cold air inside the cold air tank 161 is discharged through the air outlet tank 162. When the cold air is discharged, the movable plate 6 moves to drive the L-shaped plate 164 to move, and the L-shaped plate 164 moves to drive the blade roller 165 to move downward. The blade roller 165 moves downward and drives the gear 166 to move downward. When the gear 166 moves downward, it will mesh with the rack 163 and rotate. The rotation of the gear 166 drives the blade roller 165 to rotate, thereby simulating the actual strength, toughness and other indicators of the car wheel hub when the temperature is low in winter, and judging whether it can meet the use requirements in cold areas or low-temperature working conditions, and preventing safety problems such as wheel hub rupture due to degradation of material properties. At the same time, the rotation of the blade roller 165 can accelerate the diffusion of cold air inside the shell 2, so that cooling detection can be carried out quickly.

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

[0031] When performing strength testing, the H-shaped plate 18 moves downward, driving the pressure plate 167 to move downward. The downward movement of the pressure plate 167 will contact the force plate 1611 and apply extrusion pressure to the force plate 1611, and push the force plate 1611 to rotate forward. The rotation of the force plate 1611 drives the rotating rod 169 to rotate forward, and the rotation of the rotating rod 169 drives the telescopic rod 1610 to rotate forward, and then the telescopic rod 1610 can drive the lifting column 1612 to move upward, and the lifting column 1612 moves upward to drive the card plate 1613 to move upward, so that the front can be limited and fixed during testing, which can ensure that the wheel hub is in a stable position during the testing process 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 during testing.

[0032] The overall working principle is: the blade roller 165 moves downward, driving the gear 166 to move downward. When the gear 166 moves downward, it will mesh with the rack 163 and rotate. The rotation of the gear 166 drives the blade roller 165 to rotate, thereby simulating the real strength, toughness and other indicators of the car wheel hub when the temperature is low in winter, and judging whether it can meet the use requirements in cold areas or low temperature conditions. At the same time, the rotation of the blade roller 165 can accelerate the diffusion of cold air inside the shell 2, so that the cooling test can be carried out quickly. The rotation of the rotating rod 169 drives the telescopic rod 1610 to rotate forward, and then the telescopic rod 1610 can drive the lifting column 1612 to move upward. The upward movement of the lifting column 1612 drives the card plate 1613 to move upward, which can ensure that the wheel hub is in a stable position during the detection process.

[0033] See also Figures 1-8 On the basis of the above embodiment, 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 card plate 1613 is rotatably connected to the limiting plate 172 through a torsion spring, the bottom of the card 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 limited and fixed, the card plate 1613 moves upward to drive the limit plate 172 to move upward. When the limit plate 172 moves upward, it will gradually move away from the slot plate 171, so that the limit plate 172 can be rotated counterclockwise through the torsion spring. When the card plate 1613 rises to a certain height, the limit plate 172 will straighten to ninety degrees and be stuck on the inner wall of the slot plate 171. When the card plate 1613 is fully lifted to the required height, the lifting column 1612 will still have a certain gap with the bottom of the base 1, so that the card plate 1613 can be supported to a certain extent, thereby ensuring that the wheel hub is definitely in the inner wall of the arc-shaped base 7, avoiding the problem that the card plate 1613 has no force to support and fall when the detection is completed, and the wheel hub cannot be limited and falls off.

[0035] The top of the slot plate 171 contacts the bottom of the limit plate 172, and the limit 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 contacts 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 contact limit is needed, pressing the pressing block 176 causes it to move downward and drives the telescopic plate 175 to rotate. When the telescopic plate 175 rotates, it drives the straight plate 173 to move upward. The straight plate 173 moves upward and drives the card plate 1613 to move upward. At this time, the limit plate 172 is turned to the left to release the support of the card plate 1613, so that the card plate 1613 can fall normally and the wheel hub can be taken out normally.

[0037] The overall working principle: when the card plate 1613 rises to a certain height, the limit plate 172 will straighten to ninety degrees and be stuck in the inner wall of the card slot plate 171. When the card plate 1613 is fully lifted to the required height, there will still be a certain gap between the lifting column 1612 and the bottom of the base 1, so that the card plate 1613 can be supported to a certain extent, thereby ensuring that the wheel hub is definitely in the inner wall of the arc-shaped base 7. The support of the card plate 1613 can be released, so that the card plate 1613 can fall normally, so that the wheel hub can be taken out normally.

Any components not specified in this embodiment may be implemented using existing technologies.
