Technical Field
[0001] This utility model belongs to the field of sprocket material sample testing, specifically a sprocket material sample wear test device. Background Technology
[0002] A sprocket is a wheel with interlocking chain teeth used to mesh with precisely pitched blocks on a chain link or cable. Sprockets are widely used in mechanical transmissions in industries such as chemical engineering, textile machinery, escalators, woodworking, automated parking systems, agricultural machinery, food processing, instrumentation, and petroleum. Because sprockets require meshing transmission, they are typically manufactured from high-hardness, wear-resistant materials to ensure their lifespan.
[0003] Before producing sprockets, wear tests are usually conducted on different material samples to determine the material with the best wear resistance for sprocket production. The wear test of material samples usually involves grinding different material samples with sandpaper of the same specification. After grinding, the different material samples are weighed, and the material sample with the least weight loss is determined to be the suitable material for sprocket production.
[0004] However, existing technologies can only grind different material samples separately, which makes it impossible to accurately control the grinding force for each material sample or ensure that the grinding time for each material sample is consistent. Therefore, the test structure is not accurate enough. Moreover, when grinding the material sample, a large amount of debris is generated on the surface of the material sample. Existing technologies are not convenient for processing the debris on the material sample. After the debris accumulates in the grinding area, it will fill the gaps between the abrasive grains of the sandpaper, reduce the effective contact area between the sandpaper and the material sample, weaken the cutting ability of the sandpaper, and affect the accuracy of the wear test. Therefore, this utility model provides a sprocket material sample wear test device. Utility Model Content
[0005] To address the shortcomings of existing technologies, which only allow for separate grinding of different material samples, resulting in an inability to accurately control the grinding force and ensure consistent grinding time for each sample, thus leading to insufficient test precision, and further issues such as the generation of numerous debris on the sample surface during grinding, which existing technologies struggle to handle, and the accumulation of debris in the grinding area filling the gaps between the abrasive grains of the sandpaper, reducing the effective contact area between the sandpaper and the material sample, thereby weakening the cutting ability of the sandpaper and affecting the accuracy of the wear test, this invention proposes a sprocket material sample wear testing device.

A set of placement slots are provided, and clamps are slidably connected to the inner walls of each of the placement slots. A set of threaded rods are threadedly connected to the inner wall of the turntable at equal intervals. The ends of the threaded rods extend into the interior of the placement slots and are rotatably connected to the clamps. Four first sliding shafts are slidably connected at equal intervals to the inner wall of the first cavity and below the turntable. A grinding disc is fixedly connected to the top of the four first sliding shafts. A first spring is sleeved on the outer wall of each of the four first sliding shafts. The bottom of the first spring is fixedly connected to the first cavity, and the top of the first spring is fixedly connected to the grinding disc. A cleaning assembly is provided inside the operating table.
[0007] Preferably, the cleaning assembly includes an air pump, which is fixedly installed at the bottom of the operating table. The output end of the air pump is fixedly connected to a pipe, one end of which extends into the interior of the second cavity. The interior of the operating table has several through slots at equal intervals. The top of the through slots communicates with the first cavity, and the bottom of the through slots communicates with the second cavity. A filter plate is slidably connected to the inner wall of the collection box above the motor. The top of the filter plate is set as an annular inclined surface, and the rotating shaft passes through the filter plate.
[0008] Preferably, a fixing plate is fixedly connected to the outer wall of the rotating shaft above the filter plate.

The first protrusions and the second protrusions cooperate with each other. A vibration component is provided at the bottom of the filter plate.
[0009] Preferably, the vibration assembly includes four second sliding shafts, which are equidistantly fixedly installed at the bottom of the second cavity. Each of the four second sliding shafts has a limit block fixedly connected to its top. Each of the four second sliding shafts has a bracket slidably connected to its outer wall.

[0012] The beneficial effects of this utility model are as follows:
[0013] 1. The sprocket material sample wear test device of this utility model, by rotating the threaded rod, moves the threaded rod in the placement groove, pushes the clamping plate to move, and clamps and fixes the material sample in the placement groove, thereby fixing several material samples at the same time. By means of a first spring, the grinding disc simultaneously presses against several material samples, and the force on several material samples is the same.

[0025] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.
[0026] like Figures 1 to 7 As shown, this utility model provides a technical solution: a sprocket material sample wear testing device, including an operating table 1. A first cavity 2 is formed at the top of the operating table 1. A second cavity 3 is formed inside the operating table 1 and below the first cavity 2. A collection box 17 is fixedly connected to the inner wall of the second cavity 3. A support plate 4 is fixedly connected to the inner wall of the collection box 17. A motor 5 is fixedly connected to the top of the support plate 4. A rotating shaft 6 is fixedly connected to the output end of the motor 5. The top of the rotating shaft 6 extends into the interior of the first cavity 2 and is fixedly connected to a turntable 7. A plurality of placement slots 8 are equidistantly formed inside the turntable 7. The inner walls of the plurality of placement slots 8 are all sliding. The inner wall of the turntable 7 is connected to a clamping plate 9 and has several threaded rods 10 connected at equal intervals. The ends of the threaded rods 10 extend into the interior of the slot 8 and are rotatably connected to the clamping plate 9. Four first sliding shafts 11 are equidistantly slidably connected to the inner wall of the first cavity 2 and below the turntable 7. A grinding disc 13 is fixedly connected to the top of the four first sliding shafts 11. A first spring 12 is sleeved on the outer wall of each of the four first sliding shafts 11. The bottom of the first spring 12 is fixedly connected to the first cavity 2 and the top of the first spring 12 is fixedly connected to the grinding disc 13. A cleaning assembly is provided inside the operating table 1. A support leg 27 is fixedly connected to the bottom of the operating table 1.
[0027] Through the above technical solution, several material samples are placed into several placement slots 8 respectively. The threaded rod 10 is rotated to move within the placement slots 8, pushing the clamping plate 9 to move. When the clamping plate 9 approaches the sample material, it clamps and fixes the material sample. Through the first spring 12, the grinding disc 13 simultaneously presses against several material samples, ensuring that the force on several material samples is consistent. The motor 5 is started, driving the rotating shaft 6 to rotate, causing the turntable 7 to rotate, which in turn drives several material samples to rotate simultaneously. Thus, the grinding disc 13 grinds several material samples simultaneously, ensuring that the grinding force and time for each material sample are the same. While grinding the material samples, the cleaning component can clean the debris from the grinding, preventing debris from accumulating in the grinding area and affecting the grinding effect.
[0028] Specifically, the cleaning assembly includes an air pump 15, which is fixedly installed at the bottom of the operating table 1. The output end of the air pump 15 is fixedly connected to a pipe 16, one end of which extends into the interior of the second cavity 3. Several through slots 14 are equidistantly provided inside the operating table 1. The top of the through slots 14 communicates with the first cavity 2, and the bottom of the through slots 14 communicates with the second cavity 3. A filter plate 18 is slidably connected to the inner wall of the collection box 17 and above the motor 5. The top of the filter plate 18 is set as an annular inclined surface, and the rotating shaft 6 passes through the filter plate 18.
[0029] Using the above technical solution, the air pump 15 is started to draw air, so that the debris in the grinding area enters the second cavity 3 along the through groove 14. The debris entering the second cavity 3 falls onto the filter plate 18 and is blocked by the filter plate 18, so that the excess gas passes through the filter plate 18 and is discharged from the pipe 16. The remaining debris remains on the filter plate 18 and slides down the inclined surface at the top of the filter plate 18 into the collection box 17 for storage.
[0030] Specifically, a fixing plate 19 is fixedly connected to the outer wall of the rotating shaft 6 above the filter plate 18. Two first protrusions 20 are symmetrically fixedly connected to the bottom of the fixing plate 19, and the bottom of the first protrusions 20 is set as symmetrical inclined surfaces. Two second protrusions 21 are symmetrically fixedly connected to the top of the filter plate 18, and the top of the second protrusions 21 is set as symmetrical inclined surfaces. The first protrusions 20 and the second protrusions 21 are used in conjunction. A vibration assembly is provided at the bottom of the filter plate 18. The vibration assembly includes four second sliding shafts 22. The four second sliding shafts 22 are equidistantly fixedly installed at the bottom of the second cavity 3. Limit blocks 25 are fixedly connected to the top of each of the four second sliding shafts 22. Brackets 23 are slidably connected to the outer walls of each of the four second sliding shafts 22. The four brackets 23 are fixedly connected to the filter plate 18. A second spring 24 is sleeved on the outer walls of each of the four second sliding shafts 22. The top of the second spring 24 is fixedly connected to the bracket 23, and the bottom of the second spring 24 is fixedly connected to the second cavity 3.
[0031] Through the above technical solution, the rotating shaft 6 rotates while driving the fixed plate 19 to rotate, causing the two first protrusions 20 to rotate. When the first protrusion 20 rotates to a position close to the second protrusion 21, the inclined surface at the bottom of the first protrusion 20 presses against the inclined surface at the top of the second protrusion 21. Under the pressure of the first protrusion 20, the second protrusion 21 moves downward, driving the filter plate 18 to move downward, causing the bracket 23 to move downward, and pressing the second spring 24. When the first protrusion 20 rotates to a position away from the second protrusion 21, it loses the pressure of the first protrusion 20. Under the action of the second spring 24, the bracket 23 moves upward, driving the filter plate 18 to move upward and vibrate. This process repeats. As the rotating shaft 6 rotates, the filter plate 18 continues to vibrate upward, which facilitates the shaking of debris blocked on the filter plate 18 along the inclined surface at the top of the filter plate 18, preventing debris from accumulating on the filter plate 18 and affecting ventilation.
[0032] Specifically, a guide ring 26 is fixedly connected to the top of the inner wall of the second cavity 3. The guide ring 26 is located below the through groove 14, and the outer wall of the guide ring 26 is set as an annular inclined surface.
[0033] With the above technical solution, when the gas mixed with debris passes through the channel 14, it is guided by the guide ring 26, causing the gas to be blown downward at an angle, which makes it easier to blow the debris off the filter plate 18.
[0034] In use, several material samples are placed into several placement slots 8 respectively. The threaded rod 10 is rotated, moving within the placement slots 8 and pushing the clamping plate 9 to move. When the clamping plate 9 approaches the sample material, it clamps and fixes the material sample. The first spring 12 simultaneously presses the grinding disc 13 against several material samples, ensuring that the samples are subjected to equal force. The motor 5 is started, driving the rotating shaft 6 to rotate, causing the turntable 7 to rotate, which in turn causes the several material samples to rotate simultaneously, thereby causing the grinding disc 13 to... 3. Several material samples are polished simultaneously, ensuring that the polishing force and time are the same for each sample. While polishing the material samples, the air pump 15 is started to extract air, causing the debris in the polishing area to enter the second cavity 3 along the through groove 14. The debris entering the second cavity 3 falls onto the filter plate 18, where it is blocked. Excess gas passes through the filter plate 18 and is discharged from the pipe 16. The remaining debris remains on the filter plate 18 and slides down the inclined surface at the top of the filter plate 18 into the collection box 17. Internal storage is used. When gas mixed with debris passes through the channel 14, it is guided by the guide ring 26, causing the gas to blow downwards at an angle, which facilitates the removal of debris from the filter plate 18. Simultaneously, the rotating shaft 6 rotates, causing the fixed plate 19 to rotate, which in turn causes the two first protrusions 20 to rotate. When the first protrusion 20 rotates to a position close to the second protrusion 21, the inclined surface at the bottom of the first protrusion 20 presses against the inclined surface at the top of the second protrusion 21. Under the pressure of the first protrusion 20, the second protrusion 21 moves downwards, causing the filter plate 18 to move downwards. The movement causes the support 23 to move downwards, pressing the second spring 24. When the first protrusion 20 rotates to a position away from the second protrusion 21, it loses the pressure of the first protrusion 20. Under the action of the second spring 24, the support 23 moves upwards, causing the filter plate 18 to move upwards and vibrate. This process repeats itself. As the rotating shaft 6 rotates, the filter plate 18 continues to vibrate upwards, which facilitates the shaking of debris blocked on the filter plate 18 along the inclined surface at the top of the filter plate 18, preventing debris from accumulating on the filter plate 18 and affecting ventilation.
