Description

Technical Field

[0001] This invention relates to the field of gangue testing technology, specifically to a device and method for testing the wear resistance of steel plates based on large gangue. Background Technology

[0002] Abrasion resistance testing of gangue is typically conducted to assess its abrasion resistance under specific conditions in order to determine its suitability and durability in industrial or mining processes.

[0003] Patent application number CN202110390510.4 belongs to the technical field of wear resistance testing equipment for superhard materials, specifically relating to a wear resistance testing device. The testing device includes a device base, a grinding wheel assembly, a stage, and a dressing wheel. The grinding wheel assembly includes a grinding wheel spindle, with a grinding wheel at the end of the spindle, the grinding wheel having a grinding end face. The stage has a fixing structure for fixing components; the fixing structure is offset to one side of the grinding wheel's rotation axis, and horizontally, the fixing structure and the dressing wheel are arranged sequentially around the grinding wheel's rotation axis; the dressing wheel is detachably or movably mounted on the device base. The initial measurement of the grinding wheel is relatively accurate, which improves the accuracy of wear resistance testing. However, this device is difficult to fix and limit the gangue when testing its wear resistance. Since the gangue is of different shapes and sizes during mining, the existing fixing and clamping devices are difficult to fix it, which leads to displacement of the gangue during the testing process and affects the test results. Therefore, a steel plate wear resistance testing device and its testing method based on large gangue are 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 steel plate wear resistance testing device and testing method based on large pieces of gangue, 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 steel plate wear resistance testing device based on large pieces of gangue, including a base, and further including a clamping device, a protective device, a scraping device, and a collecting device; a guide post is fixedly connected to the left side of the base, a fixed plate is fixedly connected to the left end of the guide post, a motor is fixedly connected to the left side of the fixed plate, a threaded rod is fixedly connected to the output end of the motor, a movable plate is slidably connected to the surface of the guide post, a motor is fixedly connected to the left side of the movable plate, and a test steel plate is fixedly connected to the output end of the motor; the clamping device includes a limiting plate, a slider, a sliding rod, a clamping block, a limiting rod, a worm gear, an arc groove, and a worm, and the limiting plate is fixedly connected to the base. The inner wall of the base includes a slider slidably connected to the left side of the limiting plate, a sliding rod slidably connected to the inner wall of the slider, a clamping block fixedly connected to the end of the sliding rod away from the slider, a limiting rod fixedly connected to the right end of the slider, a worm gear rotatably connected to the inner wall of the base, an arc-shaped groove formed on the surface of the worm gear, and a worm rotatably connected to the inner wall of the base. A protective device is installed on the inner wall of the base, a scraping device is installed on the surface of the protective device, and a collecting device is installed at the bottom of the base. The surface of the limiting rod contacts the inner wall of the limiting plate, the surface of the limiting rod contacts the inner wall of the arc-shaped groove, the surface of the worm gear meshes with the surface of the worm, and a spring is sleeved on the surface of the sliding rod. The two ends of the spring are in contact with the surfaces of the clamping block and the slider, respectively. The right side of the clamping block is in contact with the left side of the limiting plate. The surface of the motor is slidably connected to the inner wall of the fixed plate. The surface of the threaded rod is threadedly connected to the inner wall of the moving plate. The surface of the threaded rod is rotatably connected to the inner wall of the fixed plate. The right end of the threaded rod is rotatably connected to the inner wall of the base. The two detection steel plates are made of Mn steel and stainless steel, respectively. When the gangue is placed between the three clamping blocks, the worm gear is driven to rotate by the set drive device. The worm gear drives the worm wheel to rotate. The worm wheel drives the limiting rod to rotate through the arc groove. However, the limiting rod is limited by the inner wall of the limiting plate and cannot rotate. Therefore, the limiting rod can only slide on the inner wall of the limiting plate. Three limit rods drive three sliders to converge. The three sliders, through the sliding rods and springs on their surfaces, drive three clamping blocks to converge. The three clamping blocks hold the gangue in place. Since the gangue has different shapes, the clamping blocks drive the sliding rods to slide within the sliders and compress the springs, allowing the three clamping blocks to effectively hold the gangue of different shapes, improving the clamping effect and preventing the gangue from falling or shifting during the detection process, thus improving the detection accuracy of the device. After clamping, the motor starts and drives the detection steel plate to rotate. At the same time, the motor starts and drives the threaded rod to rotate. The threaded rod drives the moving plate, which is limited by the guide post, to move through the thread. The moving plate drives the detection steel plate on the motor to approach the clamped gangue and perform wear resistance testing.

[0006] Preferably, the protective device includes a rack, a transmission gear, a baffle, and an elastic plate. The rack is fixedly connected to the right side of the moving plate, the transmission gear is rotatably connected to the inner wall of the base, the baffle is fixedly connected to the shaft of the transmission gear, and the elastic plate is fixedly connected to the inner wall of the baffle. The surface of the rack after movement meshes with the surface of the transmission gear. When the device is performing a test and the moving plate moves to the right, the moving plate will drive the rack to move to the right, the rack will drive the transmission gear meshing with it to rotate, and the transmission gear will drive the baffle to rotate and block the polished gangue, preventing gangue fragments from flying around during the wear resistance test and causing injury to nearby workers. At the same time, the rotation of the baffle will drive the elastic plate to rotate, so that the flying gangue comes into contact with the elastic plate on the baffle. The elastic plate can block the flying fragments and also buffer the fragments, preventing the fragments from directly hitting the baffle, reducing noise generation, reducing the impact on the baffle, and increasing its service life.

[0007] Preferably, the scraping device includes a scraper, a partition, a guide rod, and a guide groove. The scraper is slidably connected to the surface of the elastic plate, the partition is slidably connected to the surface of the baffle, the guide rod is fixedly connected to the side of the scraper away from the elastic plate, and the guide groove is formed on the front and rear sides of the moving plate. The scraping device also includes a box, a moving rod, and a push plate. The box is fixedly connected to the right side of the base, the moving rod is slidably connected to the inner wall of the box, and the push plate is fixedly connected to the end of the moving rod away from the baffle. The surface of the push plate is slidably connected to the inner wall of the box, and the end of the moving rod away from the push plate is in contact with the surface of the baffle. A spring is provided between the two push plates. The two sides of the partition are fixedly connected to the inner wall of the scraper, and the side of the partition away from the baffle... The side of the rack away from the scraper plate contacts the side of the elastic plate. When the baffle is fully rotated, the teeth on the rack will no longer contact the transmission gear. At this time, the moving plate will continue to move to the right, and the guide rod on the scraper will enter the guide groove. The guide groove will guide the guide rod, so that the guide rod drives the scraper to move on the elastic plate and the baffle. The scraper will scrape off the debris and dust accumulated on the elastic plate, preventing subsequent fragments from hitting the elastic plate and causing the previous dust to fly, thus affecting the working environment. When the rack drives the baffle to reset through the transmission gear, the baffle will contact the moving rod and push it to move. The moving rod will push the push plate to move in the box. The push plate will push the gas in the box, so that the gas blows out of the base and blows away the dust in the arc groove, preventing the presence of dust from affecting the disassembly and clamping of the gangue.

[0008] Preferably, the collecting device includes a collecting box, a secondary box, and a scraper. The collecting box is installed at the bottom of the base, the secondary box is installed on the right side of the collecting box, and the scraper is fixedly connected to the bottom of the movable plate. The collecting device also includes an outer plate, an inner plate, and a top rod. The outer plate is rotatably connected to the middle of the inner wall of the scraper via a torsion spring. The inner plate is slidably connected to the inner wall of the outer plate via an elastic element. The top rod is fixedly connected to the left side of the base. The bottom of the inner plate is in contact with the inner wall of the collecting box, the bottom of the scraper is in contact with the inner wall of the collecting box, and the right side of the inner plate after movement is in contact with the left end of the top rod. Upon contact, the sand and gravel debris from the grinding process falls into the collection box. Simultaneously, as the moving plate moves to the right, it moves the scraper, which pushes the debris in the collection box into the secondary box on the right. The secondary box is then removed, and the debris in the north is cleaned up. Compared to removing the collection box, removing the secondary box is more convenient and faster. When the scraper moves to the right, it moves the outer plate along with it. After the outer plate moves, it contacts the top rod and is pushed to rotate. The outer plate then drives the inner plate to rotate. Under the action of the elastic element, the inner plate extends out of the outer plate and further pushes the debris on the right side of the scraper into the secondary box, ensuring that the debris is pushed into the secondary box and improving the debris collection effect.

[0009] Preferably, a testing method for a steel plate abrasion resistance testing device based on large pieces of gangue includes the following steps: Step 1: When the gangue is placed between the three clamping blocks, the worm gear is rotated by the set drive device. The worm gear drives the worm wheel to rotate. The worm wheel drives the limit rod to rotate through the arc groove. However, the limit rod is limited by the inner wall of the limit plate and cannot rotate. Therefore, the limit rod can only slide on the inner wall of the limit plate. Step 2: The three limit rods will drive the three sliders to converge. The three sliders will drive the three clamping blocks to converge through the sliding rod and the spring on its surface. The three clamping blocks will clamp the gangue. Since the gangue has different shapes, the clamping blocks drive the sliding rod to slide in the slider and compress the spring, so that the three clamping blocks can clamp the gangue with different shapes well. Step 3: After clamping, the motor starts and drives the detection steel plate to rotate. At the same time, the motor starts and drives the threaded rod to rotate. The threaded rod will drive the moving plate limited by the guide post to move through the thread. The moving plate will drive the detection steel plate on the motor to approach the clamped gangue and perform wear resistance testing on it.

[0010] The present invention, by adopting the above technical solution, can bring the following beneficial effects: 1. This steel plate abrasion resistance testing device and method based on large pieces of gangue utilizes the coordinated operation of a base, guide column, fixed plate, motor, threaded rod, moving plate, motor, testing steel plate, limiting plate, slider, sliding rod, clamping block, limiting rod, worm gear, arc groove, and worm. This allows three clamping blocks to converge and hold the gangue. Since the gangue has various shapes, the clamping blocks drive the sliding rod to slide within the slider and compress the spring, ensuring the three clamping blocks effectively hold the gangue of different shapes. This improves the clamping effect, prevents the gangue from falling or shifting during testing, and enhances the testing accuracy of the device.

[0011] 2. The steel plate abrasion resistance testing device and its testing method based on large pieces of gangue, through the coordinated operation of rack, transmission gear, baffle and elastic plate, when the device is performing testing and the moving plate moves to the right, the moving plate will drive the rack to move to the right, the rack will drive the transmission gear meshing with it to rotate, the transmission gear will drive the baffle to rotate and block the gangue being ground, preventing gangue fragments from flying around during the abrasion resistance test and thus causing injury to the staff nearby.

[0012] 3. The wear resistance testing device and method for steel plates based on large pieces of gangue utilize the coordinated operation of a scraper, partition, guide rod, guide groove, box, moving rod, and push plate. When the baffle is fully rotated, the teeth on the rack will no longer contact the transmission gear. At this time, the moving plate will continue to move to the right, and the guide rod on the scraper will enter the guide groove. The guide groove will guide the guide rod, causing the guide rod to drive the scraper to move on the elastic plate and the baffle. The scraper will scrape off the debris and dust accumulated on the elastic plate, preventing subsequent fragments from hitting the elastic plate and causing the previous dust to fly up, thus affecting the working environment.

[0013] 4. The wear resistance testing device and method for steel plates based on large pieces of gangue, through the coordinated operation of the collection box, the auxiliary box, the scraper, the outer plate, the inner plate, and the top rod, the gangue debris from grinding will fall into the collection box. At the same time, when the moving plate moves to the right, it will drive the scraper to move, and the scraper will push the debris in the collection box to the auxiliary box on the right. Afterwards, the auxiliary box can be removed and the debris in the north can be cleaned. Compared with removing the collection box, the auxiliary box is more convenient and faster to remove.

[0016] 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 of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0017] Please see Figure 1-4One embodiment of the present invention is: a device and method for testing the wear resistance of steel plates based on large pieces of gangue, comprising a base 1, a clamping device 5, a protective device 6, a scraping device 7, and a collecting device 8; a guide post 2 is fixedly connected to the left side of the base 1, a fixing plate 3 is fixedly connected to the left end of the guide post 2, a motor 31 is fixedly connected to the left side of the fixing plate 3, a threaded rod 32 is fixedly connected to the output end of the motor 31, a movable plate 4 is slidably connected to the surface of the guide post 2, and a motor 41 is fixedly connected to the left side of the movable plate 4. The output end of base 1 is fixedly connected to a detection steel plate 42; the clamping device 5 includes a limiting plate 51, a slider 52, a sliding rod 53, a clamping block 54, a limiting rod 55, a worm gear 56, an arc groove 57, and a worm 58. The limiting plate 51 is fixedly connected to the inner wall of base 1, the slider 52 is slidably connected to the left side of the limiting plate 51, the sliding rod 53 is slidably connected to the inner wall of the slider 52, the clamping block 54 is fixedly connected to the end of the sliding rod 53 away from the slider 52, the limiting rod 55 is fixedly connected to the right end of the slider 52, and the worm gear 56 is rotatably connected to the inner wall of base 1. An arc-shaped groove 57 is formed on the surface of the worm gear 56, and the worm 58 is rotatably connected to the inner wall of the base 1. A protective device 6 is installed on the inner wall of the base 1, a scraping device 7 is installed on the surface of the protective device 6, and a collecting device 8 is installed at the bottom of the base 1. When gangue is placed between the three clamping blocks 54, the worm 58 is driven to rotate by the driving device. The worm 58 drives the worm gear 56 to rotate, and the worm gear 56 drives the limiting rod 55 to rotate through the arc-shaped groove 57. However, the limiting rod 55 is limited by the inner wall of the limiting plate 51 and cannot rotate. Therefore... The limiting rod 55 can only slide on the inner wall of the limiting plate 51. At this time, the three limiting rods 55 will drive the three sliders 52 to gather together. The three sliders 52 will drive the three clamping blocks 54 to gather together through the sliding rod 53 and the spring on its surface. The three clamping blocks 54 will clamp the gangue. Since the gangue has different shapes, by driving the sliding rod 53 to slide in the slider 52 and compress the spring through the clamping blocks 54, the three clamping blocks 54 can clamp the gangue with different shapes well, improve the clamping effect of the gangue, and prevent the gangue from falling or shifting during the detection process.The surface of the limiting rod 55 is in contact with the inner wall of the limiting plate 51, and the surface of the limiting rod 55 is in contact with the inner wall of the arc groove 57. The surface of the worm gear 56 meshes with the surface of the worm 58. A spring is sleeved on the surface of the slide rod 53, and the two ends of the spring are in contact with the surfaces of the clamping block 54 and the slider 52, respectively. The right side of the clamping block 54 is in contact with the left side of the limiting plate 51. The surface of the motor 41 is slidably connected to the inner wall of the fixed plate 3. The surface of the threaded rod 32 is threadedly connected to the inner wall of the moving plate 4. The surface of plate 2 is rotatably connected to the inner wall of the fixed plate 3, and the right end of the threaded rod 32 is rotatably connected to the inner wall of the base 1. The two detection steel plates 42 are made of 16Mn steel and stainless steel, respectively. After clamping, the motor 41 starts and drives the detection steel plate 42 to rotate. At the same time, the motor 31 starts and drives the threaded rod 32 to rotate. The threaded rod 32 will drive the moving plate 4, which is limited by the guide post 2, to move through the thread. The moving plate 4 will drive the detection steel plate 42 on the motor 41 to approach the clamped gangue and perform wear resistance testing on it.

[0018] The protective device 6 includes a rack 61, a transmission gear 62, a baffle 63, and an elastic plate 64. The rack 61 is fixedly connected to the right side of the movable plate 4. The transmission gear 62 is rotatably connected to the inner wall of the base 1. The baffle 63 is fixedly connected to the shaft of the transmission gear 62. When the device is performing a test and the movable plate 4 moves to the right, the movable plate 4 will drive the rack 61 to move to the right. The rack 61 will drive the transmission gear 62, which meshes with it, to rotate. The transmission gear 62 will drive the baffle 63 to rotate and block the polished gangue, preventing gangue fragments from forming during the wear resistance test. The debris splashes in all directions, potentially injuring nearby workers. The elastic plate 64 is fixedly connected to the inner wall of the baffle 63. The surface of the moving rack 61 meshes with the surface of the transmission gear 62. When the baffle 63 rotates, it drives the elastic plate 64 to rotate, causing the splashed debris to come into contact with the elastic plate 64 on the baffle 63. The elastic plate 64 can block the splashed debris and also buffer the debris, preventing the debris from directly impacting the baffle 63. This reduces noise generation, reduces the impact on the baffle 63, and increases its service life.

[0019] Working principle: When the gangue is placed between the three clamping blocks 54, the drive device rotates the worm gear 58, which in turn rotates the worm wheel 56. The worm wheel 56 rotates the limiting rod 55 through the arc groove 57. However, the limiting rod 55 is restricted by the inner wall of the limiting plate 51 and cannot rotate. Therefore, the limiting rod 55 can only slide on the inner wall of the limiting plate 51. At this time, the three limiting rods 55 will drive the three sliders 52 to converge. The three sliders 52 will drive the three clamping blocks 54 to converge through the sliding rod 53 and the spring on its surface. The three clamping blocks 54 will clamp the gangue. Since the gangue has a different shape, it is held in place by... The clamping block 54 drives the slide bar 53 to slide in the slider 52 and compress the spring, which allows the three clamping blocks 54 to hold the gangue of different shapes well, improve the clamping effect of the gangue, prevent the gangue from falling or shifting during the detection process, and improve the detection accuracy of the device. After clamping, the motor 41 starts and drives the detection steel plate 42 to rotate. At the same time, the motor 31 starts and drives the threaded rod 32 to rotate. The threaded rod 32 will drive the moving plate 4, which is limited by the guide post 2, to move through the thread. The moving plate 4 will drive the detection steel plate 42 on the motor 41 to approach the clamped gangue and perform wear resistance detection on it.

[0020] When the device is performing a test and the moving plate 4 moves to the right, the moving plate 4 will drive the rack 61 to move to the right. The rack 61 will drive the transmission gear 62 meshing with it to rotate. The transmission gear 62 will drive the baffle 63 to rotate and block the grinding gangue, preventing gangue fragments from flying around during the wear resistance test and causing injury to nearby personnel. At the same time, the rotation of the baffle 63 will drive the elastic plate 64 to rotate, so that the flying gangue can contact the elastic plate 64 on the baffle 63. The elastic plate 64 can block the flying fragments and also buffer the fragments, preventing the fragments from directly hitting the baffle 63, which can reduce noise generation, reduce the impact on the baffle 63 and increase its service life.

[0021] Please see Figure 5-7Based on the above embodiments, in another embodiment of the present invention, the scraping device 7 includes a scraper 71, a partition 72, a guide rod 73, and a guide groove 74. The scraper 71 is slidably connected to the surface of the elastic plate 64, the partition 72 is slidably connected to the surface of the baffle 63, the guide rod 73 is fixedly connected to the side of the scraper 71 away from the elastic plate 64, and the guide groove 74 is opened on the front and rear sides of the moving plate 4. When the baffle 63 is fully rotated, the teeth on the rack 61 will no longer contact the transmission gear 62. At this time, the moving plate 4 will continue to move to the right, and the guide rod 73 on the scraper 71 will enter the guide groove 74. The guide groove 74 will guide the guide rod 73, so that the guide rod 73 drives the scraper 71 to move on the elastic plate 64 and the baffle 63. The scraper 71 will scrape off the debris and dust accumulated on the elastic plate 64, preventing subsequent debris from hitting the elastic plate 64 and causing the previous dust to fly, thereby affecting the working environment. The scraping device 7 also includes a housing 741 and a moving rod 74. 42 and push plate 743, box body 741 is fixedly connected to the right side of base 1, moving rod 742 is slidably connected to the inner wall of box body 741, push plate 743 is fixedly connected to the end of moving rod 742 away from baffle 63; the surface of push plate 743 is slidably connected to the inner wall of box body 741, the end of moving rod 742 away from push plate 743 is in contact with the surface of baffle 63, a spring is provided between the two push plates 743, and both sides of partition 72 are fixedly connected to the inner wall of scraper 71. The side of the partition 72 away from the baffle 63 is in contact with the side of the elastic plate 64 away from the scraper 71. When the rack 61 drives the baffle 63 to reset through the transmission gear 62, the baffle 63 will contact the moving rod 742 and push it to move. The moving rod 742 will push the push plate 743 to move in the box 741. The push plate 743 will push the gas in the box 741 out, so that the gas blows out of the base 1 and blows away the dust in the arc groove 57, preventing the presence of dust from affecting the disassembly and clamping of the gangue.

[0022] The collection device 8 includes a collection box 81, a secondary box 82, and a scraper 83. The collection box 81 is installed at the bottom of the base 1, the secondary box 82 is installed on the right side of the collection box 81, and the scraper 83 is fixedly connected to the bottom of the moving plate 4. The grinding gangue debris falls into the collection box 81. At the same time, when the moving plate 4 moves to the right, it will drive the scraper 83 to move, and the scraper 83 will push the debris in the collection box 81 to the secondary box 82 on the right side. The secondary box 82 can then be removed and the debris in the secondary box 82 can be cleaned. Compared with removing the collection box 81, removing the secondary box 82 is more convenient and faster. The collection device 8 also includes an outer plate 831, an inner plate 832, and a top rod 833. The outer plate 831 is rotatably connected to the middle of the inner wall of the scraper 83 by a torsion spring. Plate 832 is slidably connected to the inner wall of outer plate 831 via an elastic element, and top rod 833 is fixedly connected to the left side of base 1. The bottom of inner plate 832 is in contact with the inner wall of collection box 81, and the bottom of scraper 83 is in contact with the inner wall of collection box 81. After the inner plate 832 moves, its right side is in contact with the left end of top rod 833. When scraper 83 moves to the right, it will drive outer plate 831 to move together. After the outer plate 831 moves, it will contact top rod 833 and be pushed to rotate. Outer plate 831 will drive inner plate 832 to rotate. Under the action of elastic element, inner plate 832 will extend out of outer plate 831 and push the debris on the right side of scraper 83 further into sub-box 82, ensuring that the debris is pushed into sub-box 82 and improving the debris collection effect.

[0023] Working principle: When the baffle 63 is fully rotated, the teeth on the rack 61 will no longer contact the transmission gear 62. At this time, the moving plate 4 will continue to move to the right, and the guide rod 73 on the scraper 71 will enter the guide groove 74. The guide groove 74 will guide the guide rod 73, so that the guide rod 73 drives the scraper 71 to move on the elastic plate 64 and the baffle 63. The scraper 71 will scrape off the debris and dust accumulated on the elastic plate 64 to prevent subsequent debris from hitting the elastic plate 64 and causing the previous dust to fly, thus affecting the working environment. When the rack 61 drives the baffle 63 to reset through the transmission gear 62, the baffle 63 will contact the moving rod 742 and push it to move. The moving rod 742 will push the push plate 743 to move in the box 741. The push plate 743 will push the gas in the box 741 out, so that the gas blows out of the base 1 and blows away the dust in the arc groove 57, preventing the presence of dust from affecting the disassembly and clamping of the gangue.

[0024] The polished gangue debris falls into the collection box 81. At the same time, when the moving plate 4 moves to the right, it will drive the scraper 83 to move. The scraper 83 will push the debris in the collection box 81 to the auxiliary box 82 on the right. Then, the auxiliary box 82 is removed and the debris in the north is cleaned up. Compared with removing the collection box 81, the auxiliary box 82 is easier and faster to remove. When the scraper 83 moves to the right, it will drive the outer plate 831 to move together. After the outer plate 831 moves, it will contact the top rod 833 and be pushed to rotate. The outer plate 831 will drive the inner plate 832 to rotate. Under the action of the elastic element, the inner plate 832 will extend out of the outer plate 831 and push the debris on the right side of the scraper 83 further into the auxiliary box 82, ensuring that the debris is pushed into the auxiliary box 82 and improving the debris collection effect.

6. The detection method for a steel plate abrasion resistance testing device based on large pieces of gangue according to claim 5, characterized in that: Includes the following steps: Step 1: When the gangue is placed between the three clamping blocks (54), the worm (58) is rotated by the set driving device. The worm (58) drives the worm wheel (56) to rotate. The worm wheel (56) drives the limiting rod (55) to rotate through the arc groove (57). However, the limiting rod (55) is limited by the inner wall of the limiting plate (51) and cannot rotate. Therefore, the limiting rod (55) can only slide on the inner wall of the limiting plate (51). Step 2: The three limit rods (55) will drive the three sliders (52) to converge. The three sliders (52) will drive the three clamps (54) to converge through the sliding rod (53) and the spring on its surface. The three clamps (54) will clamp the gangue. Since the gangue has different shapes, the clamps (54) will drive the sliding rod (53) to slide in the slider (52) and compress the spring, so that the three clamps (54) can clamp the gangue with different shapes well. Step 3: After clamping, the motor (41) starts and drives the detection steel plate (42) to rotate. At the same time, the motor (31) starts and drives the threaded rod (32) to rotate. The threaded rod (32) will drive the moving plate (4) limited by the guide post (2) to move through the thread. The moving plate (4) will drive the detection steel plate (42) on the motor (41) to approach the clamped gangue and perform wear resistance testing on it.
