[0002] Automobile wear-resistant parts usually refer to those parts that can maintain their original shape, size and performance for a long time during use and are not easily worn or damaged. These parts are improved in wear resistance by using special materials, processes or designs. Common automotive wear-resistant parts include tires, brake system components, engine components, transmission system components, etc., among which brake system components are the more well-known ones. Brake system components are brake pads, brake discs and other components used for braking. Brake discs often overheat or wear excessively during long downhill driving, causing damage to the brake discs, which in turn leads to failure of the brake system. Therefore, when assembling automobile brakes, it is necessary to conduct random quality inspections on the brake discs to test their wear resistance and performance under high temperature conditions to ensure product quality and reduce the probability of defective products being installed.

DETAILED DESCRIPTION

[0024] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention; it is obvious that the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments, and all other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making creative work are within the scope of protection of the present invention.

[0025] See also Figures 1 to 12A wear-resistant detection device for automobile parts comprises a base 1, a blanking shell 2 is fixedly installed on one side of the upper surface of the base 1, two symmetrical inspection doors 12 are hingedly connected to the side of the protective shell 11 close to the blanking shell 2, a protective shell 11 is fixedly installed on the side of the upper surface of the base 1 away from the blanking shell 2, a central column 3 is fixedly installed in the middle of the upper surface of the base 1, a moving rod 5 is slidingly provided inside the central column 3, a circulating component 4 is rotatably installed on the top of the central column 3, a storage bin 6 is fixedly installed inside the protective shell 11, a plurality of brake discs to be detected are stored inside the storage bin 6, and an opening on the moving rod 5 is provided. A W-shaped groove 52 is provided. When the moving rod 5 slides back and forth, the W-shaped groove 52 can drive the circulating component 4 to perform intermittent unidirectional rotation. A hydraulic cylinder 31 is fixedly installed inside the central column 3. The driving end of the hydraulic cylinder 31 is fixedly installed on the end of the moving rod 5. A connecting rod 51 is fixedly installed on the top of the moving rod 5. An upper mounting part 8 for testing wear resistance is fixedly installed on the end of the connecting rod 51 away from the moving rod 5. A lower mounting part 9 for testing wear resistance is fixedly installed on the upper surface of the base 1. The lower mounting part 9 is located directly below the upper mounting part 8. The upper mounting part 8 and the lower mounting part 9 cooperate to fix the brake disc.

[0026] In actual use, workers first stack the brake discs neatly and put them into the storage bin 6. The lower end of the storage bin 6 has an opening. The existing brake discs are composed of a disc-shaped body and two bosses for installation. A slot for connecting to the brake system is opened on the boss. The center position of the boss has a center hole that defines the center position. This is an existing brake disc structure on the market. After the brake disc to be tested is placed in the storage bin 6, the device is started. At this time, the hydraulic cylinder 31 will drive the moving rod 5 to descend. At this time, because of the W-shaped groove 52, the circulation component 4 is driven to rotate during the descent. At the same time, the circulation component 4 will take out the brake disc from the storage bin 6 and move it. When the brake disc is moved to between the upper mounting part 8 and the lower mounting part 9, the moving rod 5 will continue to descend. At this time, the upper mounting part 8 will first press against the upper surface of the brake disc, and then the upper mounting part 8 will drive the lower mounting part 9 to press against the lower surface of the brake disc, and in this process, the upper mounting part 8 and the lower mounting part 9 will clamp the screw holes on the brake disc. After the brake disc is fixed, the lower mounting part 9 will drive the brake disc to rotate. When the brake disc rotates, the upper mounting part 8 and the lower mounting part 9 can squeeze the brake disc at the same time, and then carry out wear resistance detection. During the wear resistance detection, the inspection door 12 needs to be closed to prevent damage caused by splashing debris, and the extrusion pressure and test time are set for the device in advance.

[0027] After the test is completed, the hydraulic cylinder 31 drives the moving rod 5 to rise. When the moving rod 5 rises, it will drive the circulation component 4 to rotate again. At this time, the circulation component 4 will transport the brake disc after the test to the position of the blanking shell 2 for unloading. While the circulation component 4 rotates, it will pick up the next brake disc to be tested, thereby realizing a reciprocating cycle. It can simultaneously load and unload the tested materials during the feeding action and exit action when testing the wear resistance, without the need for workers to manually load and unload, thus achieving a high degree of automation.

[0028] The blanking shell 2 has a first partition 21, a second partition 22, and a third partition 23. The first partition 21 divides the interior of the blanking shell 2 into a first chamber and a second chamber. The first partition 21, the second partition 22, and the third partition 23 are all provided with a through hole 24 at their upper ends. A first hydraulic rod 25 is fixedly installed on one side of the first partition 21 and the second partition 22. A blocking plate 26 is fixedly installed on the driving end of the first hydraulic rod 25. The blocking plate 26 is slidably clamped on one side of the third partition 23. The circulation component 4 includes a rotating ring 41. Four evenly spaced rods are fixedly installed on the outer ring of the rotating ring 41. The support rod 42 of the cloth, the end of the support rod 42 away from the rotating ring 41 is rotatably installed with a grabbing clamp 43, and the grabbing clamp 43 is fixedly installed with a blocking block 44 below the end of the support rod 42. The rotating ring 41 is sleeved on the outer surface of the moving rod 5, and the inner ring of the rotating ring 41 is installed with a convex block used in conjunction with the W-shaped groove 52. The W-shaped groove 52 has four peaks 521, and the positions of the moving rod 5 corresponding to the peaks 521 are all provided with retreat grooves 522. The peaks 521 are located to the right of the axis of the retreat groove 522, and the retreat groove 522 is used to prevent collision when the workpiece enters and exits.

[0029] When the moving rod 5 descends, the rotating ring 41 is driven by the W-shaped groove 52 to rotate until the circulation component 4 transports the brake disc to be tested to the bottom of the upper mounting part 8. At this time, the protrusion inside the rotating ring 41 will enter the inside of the retreat groove 522, and then the moving rod 5 will not drive the rotating ring 41 to rotate when it descends. At this time, the upper mounting part 8 will cooperate with the lower mounting part 9 to fix the brake disc. When rising, the retreat groove 522 is set to prevent the upper mounting part 8 from rotating before exiting the circulation component 4. The retreat groove 522 is set to give the device a certain retreat space, so that it can operate more stably. The peak 521 is used to enable the moving rod 5 to drive the rotating ring 41 to rotate in one direction regardless of whether it rises or falls.

[0030] When the circulation component 4 rotates, the grabbing clamp 43 will enter the interior of the storage bin 6 through the opening below the storage bin 6. Because the end of the grabbing clamp 43 is an arc-shaped clamp, it can clamp the boss on the brake disc, and then the brake disc will be grabbed as the circulation component 4 rotates and transported to the working position and the unloading position. When the grabbing clamp 43 rotates, the blocking block 44 is also driven to rotate. When the brake disc is processed between the upper mounting part 8 and the lower mounting part 9, it will be rotated to the top of the blanking shell 2. When unloading, the upper mounting part 8 can simultaneously detect the brake disc. If it is detected that the brake disc does not meet the test requirements, the first hydraulic rod 25 on the second partition plate 22 will work to push the blocking plate 26 to block the third partition plate 23. Then, when the grabbing clamp 43 rotates, the blocking block 44 will be blocked by the blocking plate 26. At this time, the grabbing The clamp 43 will rotate ninety degrees, and the brake disc clamped in the middle of the grabbing clamp 43 will lose its supporting force and fall into the first chamber under the action of gravity. When the brake disc is qualified, the first hydraulic rod 25 on the second partition 22 controls the blocking plate 26 to slide and open the third partition 23, and the first hydraulic rod 25 on the first partition 21 pushes the blocking plate 26 to close the third partition 23. When the circulation component 4 rotates, it will be blocked by the blocking plate 26 on the first partition 21, and the grabbing clamp 43 is blocked and rotated, so that the qualified brake disc will fall into the second chamber. The device is provided with a blanking shell 2, so that the device can automatically perform a qualification test after the wear resistance test is completed, and can automatically classify and store qualified and unqualified brake discs without the need for workers to sort and summarize, further improving the degree of automation and reducing the workload of workers.

[0031] The upper mounting portion 8 includes a first baffle plate 81, and the lower mounting portion 9 includes a motor 91. A center piece 94 is fixedly mounted on the driving end of the motor 91. A second baffle plate 92 is sleeved on the outer ring of the center piece 94. A detection portion 86 is fixedly mounted on the outside of the first baffle plate 81. The detection portion 86 is mounted on one side of the inner ring of the detection portion 86. The detection portion 86 includes a first U-shaped plate 861. A second U-shaped plate 862 is arranged above the first U-shaped plate 861. A third U-shaped plate 863 is arranged on the inner sliding card of the second U-shaped plate 862. A connecting plate 865 is connected between the second U-shaped plate 862 and the first U-shaped plate 861. One end of the connecting plate 865 close to the third U-shaped plate 863 is fixed. A first rotating shaft 866 is installed, and sliding grooves 864 are opened on both sides of the second U-shaped plate 862. The first rotating shaft 866 is movably clamped inside the sliding groove 864. One end of the connecting plate 865 is rotatably installed on the first U-shaped plate 861. The third U-shaped plate 863 is rotatably sleeved on the outside of the first rotating shaft 866. A detection probe 868 is fixedly installed on the side of the second U-shaped plate 862 close to the third U-shaped plate 863. Second rotating shafts 867 are fixedly installed on the outside of both sides of the first U-shaped plate 861 and the second U-shaped plate 862. The second rotating shaft 867 is rotatably installed on the inner circle of the protective cover 85, and a torsion spring is fixedly installed between the second rotating shaft 867 and the protective cover 85.

[0032] When the upper mounting portion 8 descends, the protective cover 85 covers the second baffle plate 92, and the first U-shaped plate 861 is pushed by the second baffle plate 92 to rotate, and then the first U-shaped plate 861 pushes the connecting plate 865, and the connecting plate 865 is rotatably mounted on the end of the first U-shaped plate 861, and the third U-shaped plate 863 is rotatably mounted on the first rotating shaft 866, so when the connecting plate 865 is driven to be pushed upward, the third U-shaped plate 863 is driven to slide along the inside of the second U-shaped plate 862, and the first rotating shaft 866 slides from one end of the slide groove 864 close to the first U-shaped plate 861 to the other end. The third U-shaped plate 863 will block the detection probe 868. When the upper mounting portion 8 rises, under the action of the torsion spring, the first U-shaped plate 861 is driven to rotate and return to its original position. At this time, the connecting plate 865 is driven to descend, and then the third U-shaped plate 863 is driven to slide down along the inside of the first baffle plate 81. The first rotating shaft 866 slides from the slide groove 864 close to one end of the first U-shaped plate 861 until the first U-shaped plate 861 and the second U-shaped plate 862 rotate to a horizontal position. At this time, the detection probe 868 is not blocked by the third U-shaped plate 863, because when the protective cover 85 descends, the device is about to perform wear resistance detection. During the wear resistance test, because the brake disc is subjected to strong friction, a large amount of debris will burst out and a large amount of heat will be generated, and even the brake disc will be broken, so that when the upper mounting part 8 descends, the detection probe 868 will not be detected but will be blocked by the third U-shaped plate 863 to prevent the bursting debris from damaging the detection probe 868, or the high temperature from causing damage to the internal components of the detection probe 868 or even measurement errors. Therefore, the device is provided with a detection part 86, so that when the upper mounting part 8 descends for wear resistance testing, the detection part 86 can protect itself, and wait for the detection to be completed, and then the upper mounting part 8 is moved to the upper mounting part 8. When the mounting part 8 is withdrawn, it can simultaneously drive the detection part 86 to open for detection work to detect whether the brake disc is qualified. It can change the detection state according to the working state to prevent the detection element from being damaged. It performs self-protection according to the working state. When the detection probe 868 detects that the brake disc is unqualified, the first hydraulic rod 25 on the second partition 22 will work to push the blocking plate 26. When the brake disc is detected to be qualified, the first hydraulic rod 25 on the second partition 22 will open, and the first hydraulic rod 25 on the first partition 21 will close. The detection probe 868 can be but is not limited to using ultrasonic sensors, laser sensors and other sensing detection equipment.

[0033] The second baffle plate 92 and the side where the second baffle plate 92 is close to each other are both provided with multiple groups of evenly distributed moving plates 82, and a test brake pad 821 is detachably installed on one side of the moving plate 82. Multiple second hydraulic rods 83 corresponding to the moving plates 82 are fixedly installed on the side where the first baffle plate 81 and the second baffle plate 92 are away from each other, and the driving end of the second hydraulic rod 83 is fixedly installed on the corresponding moving plate 82. A stepped spring 84 is sleeved on the end of the second hydraulic rod 83 close to the moving plate 82, and a rotating plate 53 is fixedly installed on the end of the connecting rod 51 away from the moving rod 5. A plurality of evenly distributed plug rods 54 are fixedly installed on the lower surface of the rotating plate 53, and a push rod 55 is fixedly installed on the middle part of the lower surface of the plug rod 54. Multiple evenly distributed spring telescopic rods 93 are fixedly installed between the motor 91 and the second baffle plate 92, and a center piece 94 is fixedly installed on the driving end of the motor 91. The movable card is arranged in the middle of the second baffle 92, and the center piece 94 includes a sealing cylinder 941. The inner center position of the sealing cylinder 941 has a central chamber 942, and the inner edge position of the sealing cylinder 941 has an edge chamber 944. The inner sliding card of the central chamber 942 is provided with a piston block 943, and a return spring 949 is fixedly installed between the piston block 943 and the central chamber 942. The central chamber 942 and the edge chamber 944 are connected through a connecting channel 945. A cover plate 946 is provided on the upper surface of the sealing cylinder 941, and the cover plate 946 is rotatably installed in the middle of the upper surface of the second baffle 92. A plurality of sleeves 948 corresponding to the insertion rod 54 are fixedly installed on the upper surface of the cover plate 946, and a plurality of piston rods 947 corresponding to the sleeves 948 are fixedly installed on the lower surface of the cover plate 946. The piston rods 947 are slidably carded inside the corresponding edge chambers 944.

[0034] When the upper mounting portion 8 is driven to descend, the first baffle plate 81 will descend and drive the rotating plate 53 to descend, and the rotating plate 53 will drive the push rod 55 to descend. At this time, the push rod 55 will pass through the center hole of the brake disc, and the insert rod 54 will enter the screw hole on the brake disc to fix the brake disc. When the push rod 55 descends, it will enter the interior of the central chamber 942. During this process, the piston block 943 is pushed down by the push rod 55. The interior of the central chamber 942 is filled with hydraulic oil. When the central chamber 942 slides, the hydraulic oil will be pushed through the connecting channel 945 into the interior of the edge chamber 944. At this time, the piston rod 947 inside the edge chamber 944 is pushed up. When the plug rod 947 rises, it will drive the cover plate 946 and the sleeve 948 to rise, and then when the upper mounting part 8 descends, the cover plate 946 and the sleeve 948 will rise synchronously, and finally the plug rod 54 will enter the sleeve 948, and the plug rod 54 and the sleeve 948 are both located inside the screw hole on the brake disc, and then the cover plate 946 and the rotating plate 53 will squeeze the brake disc, and the sleeve 948 and the plug rod 54 will fix the brake disc, and when the cover plate 946 rises, the second baffle plate 92 will also be driven to rise, and during detection, the motor 91 will drive the center piece 94 to rotate. Because the spring telescopic rod 93 is provided, the second baffle plate 92 can only move up and down, and will not be driven to rotate.

[0035] When the first baffle plate 81 descends, the second baffle plate 92 rises, and the multi-stage movable plate 82 and the test brake pad 821 are also driven to descend and rise accordingly until the test brake pad 821 fits the surface of the brake disc. If it is necessary to test the service life of the brake disc under continuous braking, the second hydraulic rod 83 does not need to work. At this time, the simulated work of long-term light braking can be achieved under the action of the graded spring 84. Because the outermost circle of the brake disc has the fastest linear speed during use, it is subjected to the greatest friction and is therefore most susceptible to damage. Therefore, a graded movable plate 82 is provided to enable different positions of the brake disc to be tested. In addition, different forces can be applied to each level of movable plates 82 through the second hydraulic rod 83, so that shear force is formed between the multi-level movable plates 82, which is convenient for testing the shear resistance of the brake disc. If the same force is applied to each second hydraulic rod 83 at the same time, the ultimate working capacity of the brake disc can be tested, and a variety of test effects can be achieved. It only needs to control the pressure of the second hydraulic rod 83 externally or set the test pressure in advance to perform a variety of wear resistance and shear resistance tests, and can test different positions of the brake disc to test the brake disc's ability to resist delamination and fracture.

[0036] Furthermore, by setting a center piece 94, the device can simultaneously drive the lower mounting part 9 below to work when the upper mounting part 8 descends for testing. On the one hand, it can automatically clamp and fix the brake disc, and on the other hand, it can drive the movable plate 82 and the test brake pad 821 to clamp both sides of the brake disc for testing, without the need for workers to manually fix it, thereby achieving automatic fixing and testing.

[0037] Working principle: when in use, the worker first stacks the brake discs neatly into the interior of the storage bin 6. The lower end of the storage bin 6 has an opening. After the brake disc to be tested is placed into the storage bin 6, the device is started. At this time, the hydraulic cylinder 31 will drive the moving rod 5 to descend. During the descent, the circulation component 4 is driven to rotate. At the same time, the circulation component 4 will take the brake disc out of the interior of the storage bin 6 and move it between the upper mounting part 8 and the lower mounting part 9. The moving rod 5 will continue to descend. At this time, the upper mounting part 8 will first press against the upper surface of the brake disc, and then the upper mounting part 8 will drive the lower mounting part 9 to work to press against the lower surface of the brake disc. In this process, the upper mounting part 8 and the lower mounting part 9 will jam the screw holes on the brake disc. After the brake disc is fixed, the lower mounting part 9 will work to drive the brake disc to rotate. When the brake disc rotates, the upper mounting part 8 and the lower mounting part 9 can squeeze the brake disc at the same time, and then perform wear resistance testing. During the wear resistance testing, the inspection door 12 needs to be closed to prevent damage caused by splashing debris, and the extrusion pressure and test time are set for the device in advance. When the brake disc is tested for wear resistance, the detection part 86 will be automatically closed and will not be tested for the quality of the brake disc. Only when the upper mounting part 8 is withdrawn will the detection part 86 be opened to test the surface of the brake disc and control the first hydraulic rod 25 to change the dropping position of qualified and unqualified brake discs for automatic classification.
