Description

Technical Field

[0001] The present invention relates to the technical field of brake pad inspection equipment, and particularly to an impact resistance inspection equipment for shock absorbers. Background Art

[0002] A shock absorber is an accessory that reduces brake noise by suppressing vibration and changing the sound wave transmission path, also known as a brake silencer. It is usually composed of a viscoelastic damping material (such as rubber, film) and a metal sheet (such as stainless steel, iron sheet) or a special paper sheet, and is installed between the brake pad back plate and the piston caliper. Its working principle is that when the brake pad and the brake disc rub to generate vibration, the sound wave is transmitted from the friction lining to the steel back and then to the silencer. The change in the sound wave intensity between different material layers can absorb energy and block resonance, thereby reducing noise transmission. The silencers of different vehicle models vary in shape and material, and some brands will customize and develop for specific vehicle models, using an automated process to ensure the installation accuracy and noise reduction effect. If the silencer is not installed or of poor quality, it may lead to increased brake noise or component detachment.

[0003] Chinese Patent discloses an automobile brake static strength detection device (authorization publication number CN117969057A). The patent includes a base assembly. Inside the base assembly, there is a load system. The load system is fixedly connected with a fixture assembly. On both sides of the base assembly, there are protective assemblies. At the upper end of the base assembly, there is a cleaning assembly. The automobile brake lining is clamped and fixed up and down by the fixture assembly. Under the drive of the load system, a shear stress load is applied. The load systems are located on both sides of the base assembly and are aligned with each other. The load application on both sides of the load system is carried out synchronously. The base assembly includes an installation table. On both sides of the upper surface of the installation table, there are columns. At the upper end of the column, there is a telescopic shaft. At the upper end of the telescopic shaft, there is a connecting block. The connecting block is fixedly connected with the top of the column. The protective assembly includes a fixed seat. The fixed seat is fixedly connected with the outer side surface of the installation table.

[0004] In the braking system, the shock absorber needs to bear the huge pressure of the caliper or piston to ensure that the brake pad can closely fit the brake disc to complete braking. If the quality of the shock absorber is poor, it will show depressions or even fractures after long-term compression and friction, which is extremely likely to cause safety accidents such as brake failure. Therefore, the impact resistance of the shock absorber must be strictly detected. However, in the above patent and the prior art, it is impossible to continuously perform rapid impact tests on multiple shock absorbers, resulting in low detection efficiency and difficult to meet the actual production requirements. For this reason, we propose an impact resistance inspection equipment for shock absorbers. Summary of the Invention

[0011] As a further solution of the present invention, rotating shafts are rotatably connected to the left and right side walls of the flipping square block. At the opposite ends of the two rotating shafts, pressing plates are fixedly connected. A folding plate is fixedly connected between the two rotating shafts.

[0038] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. 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 creative work are within the scope of protection of the present invention.

[0039] Example 1: Please refer to Figures 1 to 5, in the embodiment of the present invention, an impact resistance inspection device for shock-absorbing sheets includes a frame assembly 1. The frame assembly 1 includes a frame 101. A sliding frame 102 is fixedly connected to the frame 101 through a plurality of cross bars. A stacking frame 103 is communicated and fixed to the upper side wall of the sliding frame 102. A plurality of inspection components 2 are arranged in the stacking frame 103 in sequence from top to bottom. Chutes 104 are formed between the inner walls of the front and rear sides of the sliding frame 102 and the stacking frame 103. A plurality of inspection components 2 are slidably connected to the inside of the stacking frame 103 through the chutes 104 on the stacking frame 103. A top block 105 is slidably connected to the inside of the sliding frame 102. The designed height of the top block 105 is lower than that of the lowermost inspection component 2. In this way, when the top block 105 moves to push the lowermost inspection component 2, the other stacked inspection components 2 above will not block the top block 105, enabling the top block 105 to smoothly push the target. Moreover, a convex block is fixedly connected to the end of the top block 105 close to the inspection component 2. The convex block is used to simulate the slave cylinder in the braking structure. A cylinder 106 is fixedly connected between the frame 101 and the top block 105. The cylinder 106 can be used to push the top block 105 to move. During the inspection process, the staff needs to adjust the impact force of the cylinder 106 according to the material of the shock-absorbing and sound-insulating sheet 203;

[0040] The inspection component 2 includes an inspection block 201. A groove is drilled in the inspection block 201. Sliders 202 matching the sliding grooves 104 are fixedly connected to both the left and right side walls of the inspection block 201. A shock-absorbing and sound-insulating sheet 203 is snap-connected to the inspection block 201. The shock-absorbing and sound-insulating sheet 203 can be snapped or adhered to the inspection block 201 according to different models. An inspection hole 204 with a diameter smaller than the width of the shock-absorbing and sound-insulating sheet 203 is drilled in the inspection block 201. The diameter of the convex block fixedly connected to the top block 105 is smaller than that of the inspection hole 204. A spring plate 205 is fixedly connected inside the inspection hole 204. A magnetic block 206 and a top plate 207 are slidably connected inside the inspection hole 204. Two connecting rods 208 are fixedly connected between the magnetic block 206 and the top plate 207. A rubber sleeve is wrapped around the surface of the connecting rod 208. The function of the rubber sleeve is to increase the resistance when the connecting rod 208 moves. In this way, when the inspection component 2 is quickly pushed to the bottom plate 404, the magnetic block 206 will not move due to large inertia. And both connecting rods 208 penetrate through the spring plate 205. A spring 209 is fixedly connected between the spring plate 205 and the top plate 207, so that the top plate 207 abuts against the shock-absorbing and sound-insulating sheet 203 under the thrust of the spring 209. At this time, the distance between the magnetic block 206 and the magnetic plate 303 is relatively far, and the magnetism is weak. When the shock-absorbing and sound-insulating sheet 203 is damaged due to impact during failed inspection, the convex block on the top block 105 will push the top plate 207, so that the top plate 207 can push the magnetic block 206 closer to the magnetic plate 303, enabling the magnetic block 206 to be adsorbed on the bottom plate 404 under the action of magnetism. A magnetic adsorption component 3 for magnetically adsorbing the inspection component 2 is fixedly connected to the stacking frame 103. A swinging component 4 for driving the inspection component 2 to simulate a vibration environment is fixedly connected inside the magnetic adsorption component 3. A flipping component 5 for driving the flipping square 304 to flip is fixedly connected to the upper side wall of the frame 101. A blanking chute 6 for collecting the inspection component 2 is inserted into the transmission box 502.

[0041] The magnetic adsorption component 3 includes a horizontal plate 301 fixedly connected to the side wall of the stacking frame 103. A fixed column 302 is fixedly connected to the lower side wall of the horizontal plate 301. Two symmetrically arranged magnetic plates 303 are fixedly connected inside the fixed column 302. And the magnetic plate 303 close to the inspection component 2 is magnetically attracted to the magnetic block 206. When the flipping square 304 flips 180 degrees, the magnetic block 206 adsorbed on the bottom plate 404 is magnetically repelled by the other magnetic plate 303, enabling the inspection component 2 to fall. The flipping square 304 is rotatably connected to the fixed column 302 through a bearing.

[0042] The swing assembly 4 includes a motor 401 fixedly connected to the upper side wall of the horizontal plate 301, a cylindrical cavity is excavated inside the fixed column 302, and a rotating rod 402 is rotatably connected inside the cavity through a bearing, and the output end of the motor 401 is fixedly connected to the upper end of the rotating rod 402, and the left and right side walls of the flip block 304 are plugged and rotatably connected with a rotating shaft 403, and the ends of the two rotating shafts 403 that are separated from each other are fixedly connected with a support plate 404. When the cylinder 106 pushes the top block 105 to move quickly, it can The top block 105 pushes the inspection block 201, so that the inspection block 201 is against the abutment plate 404, and the top block 105 impacts the shock-absorbing and sound-absorbing plate 203. It is worth noting that when the inspection block 201 is separated from the sliding frame 102, the inspection block 201 will not fall immediately due to the action of inertia. At the same time, the top block 105 has a certain speed, so that the moving inertia of the inspection block 201 is increased, ensuring that the inspection block 201 can accurately hit the abutment plate 404, and the two rotating shafts 403 are A folding plate 405 of a C-shaped structure is fixedly connected between the rotating rod 402 and a guide groove 406 is cut on the folding plate 405. A circular plate 407 is fixedly connected to the lower end of the rotating rod 402. A guide column 408 is eccentrically fixedly connected to the circular plate 407, and the guide column 408 penetrates and is slidably connected to the inside of the guide groove 406. When the motor 401 drives the rotating rod 402 to rotate, the rotating rod 402 drives the guide column 408 to rotate through the circular plate 407. The guide column 408 can slide in the guide groove 406 to make the folding rod 402 rotate. The plate 405 is constantly swinging, so that the folding plate 405 drives the abutting plate 404 to continuously swing, and the abutting plate 404 drives the inspection block 201 to continuously swing, thereby helping the inspection component 2 to simulate the scene when the brake pad and the brake disc are against each other and generating vibration, thereby increasing the friction between the shock-absorbing and sound-absorbing plate 203 and the protrusion of the top block 105. It is worth noting that during the startup of the motor 401, the flip block 304 can still rotate, and it will not affect the rotation of components such as the rotating rod 402.

[0043] Example 2: Please refer to Figures 6 to 9, on the basis of Embodiment 1, the flipping component 5 includes a rotating column 501 fixedly connected to the lower end of the flipping square block 304, and the rotating column 501 is rotatably connected to the frame 101. A transmission box 502 is fixedly connected to the upper side wall of the frame 101, and the transmission box 502 is rotatably connected to the rotating column 501 through a bearing. A worm gear 503 is fixedly connected to the lower end of the rotating column 501. A worm 504 is rotatably connected between the front and rear inner walls of the transmission box 502, and the worm 504 meshes with the worm gear 503. Through the meshing of the worm gear 503 and the worm 504, the worm gear 503 cannot drive the worm 504 to rotate, while the worm 504 can drive the worm gear 503 to rotate. Through this mechanism, when the worm 504 does not rotate, the worm gear 503 and the flipping square block 304 are in a self-locking state. Both ends of the worm 504 are rotatably connected with gears 505 through one-way bearings 506. The one-way bearing 506 can only rotate in one direction. Its principle and structure are both prior arts and will not be elaborated here. Two racks 507 are slidably connected inside the transmission box 502, and both racks 507 mesh with the gears 505. When the top block 105 drives the rack 507 to move towards the flipping square block 304 through the transmission column 509 and the push block 508, the rack 507 can only drive the gear 505 to rotate, and the gear 505 cannot drive the worm 504 to rotate through the one-way bearing 506. When the top block 105 returns to its original position, the rack 507 also returns to its original position. At this time, the gear 505 drives the worm 504 to rotate through the one-way bearing 506, so that the worm 504 drives the worm gear 503 to rotate, and the worm gear 503 drives the flipping square block 304 to flip through the rotating column 501. It should be noted that the tooth surface length of the rack 507 is limited. Therefore, when the top block 105 moves close to the flipping square block 304, the tooth surface of the rack 507 no longer contacts the gear 505. In this way, it can be prevented that after the shock-absorbing and sound-insulating sheet 203 is damaged, due to the longer moving stroke of the top block 105, the flipping angle of the flipping square block 304 is excessive. Through the limitation of the tooth surface length, when the rack 507 returns to its original position, the gear 505 can rotate a fixed number of turns. This number of turns can ensure that the flipping square block 304 rotates 180 degrees. A push block 508 is slidably connected inside the transmission box 502, and a transmission column 509 is fixedly connected between the push block 508 and the top block 105.

[0044] The working principle of the present invention is:

[0045] When the present invention is in use, after the inspection component 2 to be inspected is placed inside the stacking frame 103 by the staff, the air cylinder 106 is started to drive it to push the top block 105 to move. The top block 105 pushes the lowermost inspection component 2 through horizontal movement. By using the movement speed and inertia of the inspection component 2, the inspection block 201 remains in a suspended state when it breaks away from the sliding frame 102 and stably contacts the abutting plate 404 to avoid falling. At the same time, the convex block of the top block 105 impacts the shock-absorbing and sound-insulating sheet 203. Meanwhile, the motor 401 drives the rotating rod 402 to rotate. The rotating rod 402 drives the guiding column 408 to rotate through the circular plate 407. The guiding column 408 can make the folding plate 405 swing continuously through sliding inside the guiding groove 406. Then the folding plate 405 drives the abutting plate 404 to swing reciprocally, and the abutting plate 404 drives the inspection block 201 to swing continuously, so as to help the inspection component 2 simulate the scenario when the brake pad and the brake disc are in contact and generate vibration. At this time, the inspection block 201 drives the shock-absorbing and sound-insulating sheet 203 to swing continuously, making the shock-absorbing and sound-insulating sheet 203 continuously rub against the convex block of the top block 105, so as to test the wear resistance of the shock-absorbing and sound-insulating sheet 203;

[0046] Through the impact of the convex block of the top block 105 on the shock-absorbing and sound-insulating sheet 203, the shock-absorbing and sound-insulating sheet 203 with poor quality will be pierced by the convex block. At this time, the convex block will continue to move forward for a certain distance, so that the convex block pushes the top plate 207, and then pushes the magnetic block 206 to approach the magnetic plate 303. As the distance gets closer and closer, the magnetism gets stronger and stronger until the magnetic block 206 can be adsorbed on the abutting plate 404 under the magnetic attraction of the magnetic plate 303. When the shock-absorbing and sound-insulating sheet 203 passes the inspection, it will not be damaged by the impact. When the top block 105 resets, the inspection component 2 will directly fall and fall into the blanking chute 6;

[0047] Subsequently, the air cylinder 106 pulls the top block 105 to reset, so that the new inspection component 2 falls into the sliding frame 102. At the same time, in this process, when the top block 105 resets, it will also drive the rack 507 to move towards the flipping square 304 through the transmission column 509 and the push block 508. The rack 507 can only drive the gear 505 to rotate, and the gear 505 cannot drive the worm 504 to rotate through the one-way bearing 506. When the top block 105 returns to its position, the rack 507 also returns to its position. At this time, the gear 505 drives the worm 504 to rotate through the one-way bearing 506, so that the worm 504 drives the worm gear 503 to rotate. The worm gear 503 drives the flipping square 304 to flip 180 degrees through the rotating column 501. When the flipping square 304 flips, the inspection block 201 adsorbed on the abutting plate 404 flips together. When the inspection block 201 is about to flip to the other side, because the magnetic plate 303 on the other side repels the magnetic block 206, the inspection component 2 will fall from the other side and will not fall into the blanking chute 6. In this way, it can play a role in distinguishing the inspection of the inspection component 2 and improve the inspection efficiency of the inspection component 2.

[0048] The above are only the preferred specific embodiments of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention should cover within the protection scope of the present invention by making equivalent substitutions or changes according to the technical solution and inventive concept of the present invention.
