When the slip rate of the automobile tire is detected, if the supporting plate 202 is not in a horizontal state, jolt occurs when the subsequent automobile tire runs to the top of the sand bonding layer 203, and the inclined state of the supporting plate 202 also can cause obstruction to the normal running of the automobile tire, so that the slip rate quality detection precision of the tire is affected; meanwhile, when four automobile tires all travel to the tops of the four sand-bonding layers 203 at a constant speed and then start braking and quality inspection, but only an operator manually operates the moment of starting the braking, the operation precision is low, the operation difficulty is high, and the automobile tires move to the tops of the sand-bonding layers 203 and apply acting force to the support plates 202 instantly, so that the support plates 202 incline and the quality inspection precision is affected; however, when the movement distance of the automobile tire after braking is too large due to misoperation of operators, the automobile tire drives the supporting plate 202 to slide by friction force with the sand-bonding layer 203 and is easy to damage the supporting plate 202 finally, so that the durability and stability of the supporting plate 202 are affected; in the prior art, only the quality inspection of the sliding rate of the automobile tire in the horizontal direction can be realized, but the quality inspection of the sliding rate of the automobile tire under different gradients cannot be realized, so that the quality inspection efficiency is low, the quality inspection effect is poor, the quality inspection range is small, and the quality inspection precision is low.
In order to solve the above problem, when the tire slip ratio quality inspection apparatus is in actual use, before inspecting the quality of an automobile tire, the wedge-shaped surfaces 207 at the bottom of the support plate 202 are all in contact with the matching surfaces 215, the electromagnetic block 209 is powered off, the matching rods 213 are driven to be at the initial positions under the action of the elastic force of the return springs 211, at this time, the support plate 202 applies an acting force to the tops of the matching rods 213, the matching rods 213 drive the magnetic slide plate 212 to move to a proper position inside the side groove 208, the distance sensor 218 detects a distance value, if the distance values detected by the distance sensor 218 all reach the preset distance value, this time, the support plate 202 is stably located between the matching rods 213, the support plate 202 is at a proper position, the sand-bonding layer 203 at the top of the support plate 202 is at the same level as the top of the base 101, and the whole quality inspection assembly 2 is stably set.
When the distance values detected by the distance sensors 218 are not equal and are not equal to the preset distance value, it is indicated that the supporting plate 202 is inclined due to the existence of chips and the like at the top of the sand-bonding layer 203, and the surface of the sand-bonding layer 203 needs to be cleaned in advance, and when the distance value detected by the distance sensor 218 at one side is smaller than the preset distance value, it is indicated that the supporting plate 202 is inclined to the side, then the control screen 105 firstly controls the energizing current of the electromagnetic block 209 to continuously change, then the magnetic repulsive force of the electromagnetic block 209 to the magnetic sliding plate 212 continuously changes and drives the supporting plate 202 to vibrate up and down, and further the impurities and the like at the top of the sand-bonding layer 203 are cleaned.
After the automobile moves up to the top of the base 101 along the upper frame 102 under the guidance of the indicator 110, the automobile tire is first in extrusion contact with the two sand-bonding layers 203 close to the upper frame 102, at this time, under the action of gravity of the automobile, the supporting plate 202 is driven by the sand-bonding layers 203 to apply downward force on one side close to the upper frame 102, the supporting plate 202 applies downward force on the matching rod 213, the matching rod 213 drives the magnetic sliding plate 212 to extrude the return spring 211 along the side groove 208 to move towards the end close to the electromagnetic block 209, and the distance value detected by the distance sensor 218 is reduced.
Then the control screen 105 controls the current of the electromagnetic block 209 at the corresponding position to increase, the magnetic repulsive force of the electromagnetic block 209 to the magnetic slide plate 212 increases and drives the magnetic slide plate 212 to stretch the reset spring 211 to move towards the end far away from the electromagnetic block 209, the distance value detected by the distance sensor 218 increases to the preset distance value, and the magnetic slide plate 212 drives the matching rod 213 to synchronously move and increase the supporting force to the supporting plate 202, so that the supporting plate 202 is still in a horizontal state, the supporting stability of the supporting plate 202 to the automobile tire is improved, and the automobile tire is ensured to stably and efficiently run.
Along with the continuous movement of the automobile at the top of the base 101, four automobile tires all move to the top of the corresponding sand-bonding layer 203, at this time, after the four sand-bonding layers 203 receive extrusion force, the extrusion force applied to the matching rods 213 by the supporting plates 202 increases, the matching rods 213 drive the magnetic sliding plates 212 to extrude the reset springs 211 and move towards the electromagnetic blocks 209, at this time, the pressure values detected by the four distance sensors 218 are all reduced, which indicates that the four automobile tires all reach proper positions to brake and detect the sliding rate of the tires, then the control screen 105 controls the electromagnetic blocks 209 at the corresponding positions to increase the electrifying current and drive the magnetic sliding plates 212 to stretch the reset springs 211 to move towards the end far away from the electromagnetic blocks 209 through the magnetic repulsive force of the magnetic sliding plates 212, the magnetic sliding plates 212 drive the matching rods 213 to move and keep stable support of the supporting plates 202, and prompt operators to brake the automobile, so that the braking accuracy is effectively improved, and the quality inspection accuracy of the sliding rate is correspondingly improved.

If the distance of the movement of the automobile tire at the top of the sand bonding layer 203 is increased and the distance of the movement of the supporting plate 202 towards the end close to the lower frame 103 is increased continuously due to misoperation of operators, the supporting plate 202 drives the matching rod 213 and the magnetic sliding plate 212 to move continuously, when the distance value detected by the distance sensor 218 is reduced continuously and is smaller than the minimum value of the distance, the supporting plate 202 is at risk of being damaged by extrusion, the corresponding control screen 105 controls the energizing current of the electromagnetic block 209 close to the end of the lower frame 103 to increase to the maximum value, the magnetic repulsive force exerted by the electromagnetic block 209 on the magnetic sliding plate 212 is increased to the maximum value and drives the magnetic sliding plate 212 to stretch the reset spring 211 to move towards the end far from the electromagnetic block 209 to the maximum value, the magnetic sliding plate 212 synchronously drives the matching rod 213 to move, the wedge-shaped extrusion force of the matching rod 213 and the supporting plate 202 is increased, the wedge-shaped matching lower supporting plate 202 is inclined upwards at one side close to the lower frame 103 due to wedge-shaped matching of the wedge-shaped surface 207 and the matching surface 215, the corresponding supporting plate 202 is inclined and the movement of the automobile tire is prevented from being damaged, the damage caused by the electromagnetic block is effectively avoided, the magnetic repulsion of the automobile tire is greater than the moving distance of the supporting plate 202, the magnetic sliding plate is more protected, and the protection is more stable.
Meanwhile, when different gradients need to be detected, after four automobile tires uniformly run to the top of the sand-bonding layer 203, the control screen 105 controls a plurality of electromagnetic blocks 209 close to one side of the upper frame 102 to increase in electrifying current, the electromagnetic blocks 209 increase magnetic repulsive force of the magnetic sliding plate 212 and drive the magnetic sliding plate 212 to stretch the reset spring 211 to move far away from the electromagnetic blocks 209, the distance value detected by the distance sensor 218 increases, meanwhile, the magnetic sliding plate 212 drives the matching rod 213 to synchronously move and increase the extrusion force of the supporting plate 202, the supporting plate 202 inclines upwards under the action of the extrusion force, the current of the electromagnetic blocks 209 close to the lower frame 103 increases but is smaller than that of the other side, the supporting plate 202 inclines downwards along the direction from the upper frame 102 to the lower frame 103 under the action of the extrusion force, the inclination angles of the four supporting plates 202 are the same, and the inclination angles of the supporting plate 202 can be obtained through the distance values detected by the plurality of the distance sensors 218.
When the quality inspection of the automobile tires is finished, an operator drives the automobile to drive away from the top of the base 101 along the lower frame 103, meanwhile, as the automobile tires and the sand-bonding layer 203 are mutually extruded and braked and scraps are easy to generate, at the moment, the control screen 105 controls the electrifying current of the electromagnetic block 209 to continuously change, then the electromagnetic block 209 is matched with the reset spring 211 to drive the magnetic sliding plate 212 to continuously reciprocate in the side groove 208, the magnetic sliding plate 212 drives the matching rod 213 to synchronously reciprocate transversely, by means of the wedge-shaped matching of the wedge-shaped surface 207 and the matching surface 215, when the matching rod 213 extrudes the supporting plate 202 and moves far away from the end of the electromagnetic block 209, the supporting plate 202 moves upwards through the hinged seat 216 and the moving rod 206, and meanwhile, when the matching rod 213 moves reversely and reduces the extrusion force to the supporting plate 202, the supporting plate 202 is driven to move downwards through the moving rod 206 and the hinged seat 216 under the action of the elasticity of the supporting spring 205, then the matching rod 213 drives the supporting plate 202 to vibrate up and down in the bottom groove 201, the supporting plate 202 drives the sand-bonding layer 203 to vibrate up and down in the bottom groove 201, and the vibration cleaning effect to the scraps on the top of the sand-bonding layer 203 is further improved.
