Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Example 1

[0022] Please see Figure 1-4 The present invention provides the following technical solution: an oil-impregnated bearing chamfering device, comprising a worktable 1, a mounting bracket 4 fixedly connected to the upper end of the worktable 1, a cylinder 5 connected to the upper end of the mounting bracket 4, a motor 6 disposed below the cylinder 5, a grinding disc 7 disposed below the motor 6, a grinding groove 10 opened at the lower end of the grinding disc 7, electric push rods 8 connected to the lower ends of both ends of the worktable 1, an arc-shaped clamping plate 9 disposed at the output end of the electric push rod 8, the grinding disc 7 and the motor 6 being connected by a connecting component 3, and a cleaning component 2 disposed at the rear end of the worktable 1.

[0023] Specifically, the cleaning component 2 includes a folding plate 21, a rectangular groove 22, a second motor 23, a lead screw 24, a moving plate 25, a connecting frame 26, a scraper 27, and a collection component 28. The folding plate 21 is welded to the middle of the rear end of the workbench 1. The second motor 23 is located at the rear end of the folding plate 21. The lead screw 24 is located at the output end of the second motor 23. The moving plate 25 is threaded onto the surface of the lead screw 24. The lower end of the moving plate 25 is pressed against the upper end of the folding plate 21. The scraper 27 is located on the rear side of the upper end of the workbench 1. The lower end of the scraper 27 is pressed against the upper end of the workbench 1. The upper end of the scraper 27 is flush with the lower end of the arc-shaped clamp 9. The scraper 27 and the moving plate 25 are connected by the connecting frame 26. A rectangular groove 22 is opened on the front side of the workbench 1 at the position corresponding to the scraper 27. The collection component 28 is located at the lower end of the workbench 1 at the position corresponding to the rectangular groove 22.

[0024] By adopting the above technical solution, after the chamfered oil-impregnated bearing is removed from the worktable 1, the motor 23 is turned on to drive the lead screw 24 to rotate. The rotation of the lead screw 24 drives the moving plate 25 to move in the folding plate 21. The movement of the moving plate 25 pushes the scraper 27 to move through the connecting frame 26. The movement of the scraper 27 can push the waste on the worktable 1 where the oil-impregnated bearing is placed forward. The waste falls through the rectangular groove 22. By setting the cleaning component 2, the position where the oil-impregnated bearing is placed on the worktable 1 can be automatically cleaned, so as to avoid the stability of subsequent oil-impregnated bearing placement when there is waste on the position where the oil-impregnated bearing is placed on the worktable 1.

[0025] Specifically, the collection component 28 includes a fixed plate 281, a collection box 282, a handle 283, a placement slot 284, and a rotating plate 285. The workbench 1 is provided with a fixed plate 281. The collection box 282 is provided at the position on the upper end of the fixed plate 281 corresponding to the rectangular slot 22. The upper end of the fixed plate 281 is provided with a placement slot 284 corresponding to the collection box 282. The handle 283 is fixedly connected to the front end of the collection box 282. The rotating plate 285 is connected to the front end of the workbench 1 at the position corresponding to the collection box 282 through damping rotation. After the collection box 282 is installed into the placement slot 284, one end of the rotating plate 285 is flush with the front end of the collection box 282.

[0026] By adopting the above technical solution, the handheld collection box 282 is placed into the placement slot 284 of the fixed plate 281, and then the rotating plate 285 is moved to limit the collection box 282. The collection box 282 can collect the waste falling in the rectangular slot 22. By setting the collection component 28, the cleaned waste can be collected in a centralized manner.

[0027] In this embodiment, when using the oil-impregnated bearing chamfering device, the device is installed in a suitable position, the oil-impregnated bearing is placed on the worktable 1, and the electric push rod 8 is turned on to move the arc-shaped clamping plate 9 to clamp and fix the oil-impregnated bearing. Then, the cylinder 5 pushes the motor 6 to move downward, and at the same time, the grinding disc 7 on the lower side of the motor 6 moves downward, so that the end face of the oil-impregnated bearing enters the grinding groove 10. The motor 6 is turned on to drive the grinding disc 7 to rotate and grind and chamfer the oil-impregnated bearing. After the chamfered oil-impregnated bearing is removed from the worktable 1 by setting the cleaning component 2, the motor 23 is turned on to drive the lead screw 24 to rotate. The rotation of the lead screw 24 drives the moving plate 25 to move in the folding plate 21. The movement of the moving plate 25 is connected by the connecting frame. 26. Push the scraper 27 to move. The movement of the scraper 27 can push the waste debris on the workbench 1 where the oil-impregnated bearing is placed forward. The waste debris falls through the rectangular groove 22. By setting the cleaning component 2, the oil-impregnated bearing position on the workbench 1 can be automatically cleaned, so as to avoid the impact of waste debris on the subsequent placement stability of the oil-impregnated bearing when there is waste debris on the workbench 1 where the oil-impregnated bearing is placed. By setting the collection component 28, the collection box 282 is placed into the placement groove 284 of the fixed plate 281 by hand. Then, the rotating plate 285 is turned to limit the collection box 282. The collection box 282 can collect the waste debris falling from the rectangular groove 22. By setting the collection component 28, the cleaned waste debris can be collected in a centralized manner.

[0028] Example 2

[0029] The difference between this embodiment and embodiment 1 is that the connecting component 3 includes a fixed base 31, a plug plate 32, a slot 33, a fixing bolt 34, a fixing hole 35, a through hole 36, and a clamping component 37. The output end of the motor 6 is provided with a fixed base 31, the upper end of the arc-shaped clamp 9 is fixedly connected to the plug plate 32, the lower end of the fixed base 31 is provided with a slot 33 corresponding to the plug plate 32, the plug plate 32 and the fixed base 31 are connected by a fixing bolt 34, the plug plate 32 is provided with a fixing hole 35 corresponding to the fixing bolt 34, one end of the fixed base 31 is provided with a through hole 36 corresponding to the fixing bolt 34, and the motor 6 and the cylinder 5 are connected by the clamping component 37.

[0030] By adopting the above technical solution and setting the connecting component 3, when installing the grinding disc 7, the upper end of the insert plate 32 of the grinding disc 7 is inserted into the slot 33 at the lower end of the fixing base 31. Then, the fixing bolt 34 is inserted into the through hole 36 of the fixing base 31, and one end of the fixing bolt 34 is screwed into the fixing hole 35 of the insert plate 32, so as to achieve the effect of limiting and fixing the insert plate 32 and the grinding disc 7. By setting the connecting component 3, the grinding disc 7 can be disassembled and replaced, avoiding the wear of the grinding disc 7 after long-term use from affecting the subsequent chamfering quality.

[0031] Specifically, the clamping assembly 37 includes a fixed frame 371, a sliding plate 372, a sliding column 373, a fixed rod 374, and a spring 375. The output end of the cylinder 5 is provided with a fixed frame 371, and the sliding plate 372 is slidably connected in the fixed frame 371. The motor 6 is connected to the sliding plate 372 through the sliding column 373. The fixed rod 374 is fixedly connected to both sides inside the fixed frame 371. The sliding plate 372 has sliding holes on both sides corresponding to the fixed rod 374. The spring 375 is sleeved on the outside of the fixed rod 374 at the upper end of the sliding plate 372.

[0032] By adopting the above technical solution, when the cylinder 5 pushes the grinding disc 7 to press against the oil-impregnated bearing, the cylinder 5 continues to push the grinding disc 7 to move downward. At the same time, the sliding column 373 at the upper end of the motor 6 pushes the sliding plate 372 to move in the fixed frame 371. The sliding plate 372 moves and compresses the spring 375 on the fixed rod 374. The spring 375 can be used to press the grinding disc 7 against the oil-impregnated bearing. By setting the pressing component 37, the contact between the grinding disc 7 and the oil-impregnated bearing can play a buffering and protective role, avoiding excessive downward movement of the grinding disc 7 and causing pressure damage to the oil-impregnated bearing.

[0033] Specifically, the slide column 373 and the motor 6, as well as the slide column 373 and the slide plate 372, are all spot welded together. After the insert plate 32 enters the slot 33, the insert plate 32 is in close contact with the inner wall of the slot 33.

[0034] By adopting the above technical solution, spot welding makes the connection between the slide column 373 and the motor 6, as well as between the slide column 373 and the slide plate 372, more secure. After the insert plate 32 enters the slot 33, the insert plate 32 is more stable in the slot 33.

[0035] In this embodiment, when installing the grinding disc 7 using the connecting component 3, the upper insert plate 32 of the grinding disc 7 is inserted into the slot 33 at the lower end of the fixing base 31. Then, the fixing bolt 34 is inserted into the through hole 36 of the fixing base 31, and one end of the fixing bolt 34 is screwed into the fixing hole 35 of the insert plate 32. This achieves the effect of limiting and fixing the insert plate 32 and the grinding disc 7. By using the connecting component 3, the grinding disc 7 can be disassembled and replaced, avoiding wear and tear on the grinding disc 7 over a long period of use, which would affect the subsequent chamfering quality. By setting the clamping component 37, when the cylinder 5 pushes the grinding disc 7 to press against the oil-impregnated bearing, the cylinder 5 continues to push the grinding disc 7 downward. At the same time, the sliding column 373 at the upper end of the motor 6 pushes the sliding plate 372 to move in the fixed frame 371. The sliding plate 372 moves and compresses the spring 375 on the fixed rod 374. The spring 375 can be used to press the grinding disc 7 against the oil-impregnated bearing. By setting the clamping component 37, the contact between the grinding disc 7 and the oil-impregnated bearing can be buffered and protected, avoiding excessive downward movement of the grinding disc 7 and causing pressure damage to the oil-impregnated bearing.

[0036] In this utility model, motor 23 is a previously disclosed technology, and the selected model is 5IK120GN-CF.

[0037] The structure and working principle of the workbench 1, mounting bracket 4, cylinder 5, motor 6, grinding disc 7, electric push rod 8, arc-shaped clamping plate 9, and grinding groove 10 in this utility model have been disclosed in a chamfering device for oil-impregnated bearings disclosed in Chinese patent application number 2024204219958. Its working principle is to place the oil-impregnated bearing on the workbench 1, activate the electric push rod 8 to push the arc-shaped clamping plate 9 to move and clamp and fix the oil-impregnated bearing, then the cylinder 5 pushes the motor 6 to move downward, and at the same time the grinding disc 7 on the lower side of the motor 6 moves downward, and the end face of the oil-impregnated bearing enters the grinding groove 10. Activating the motor 6 drives the grinding disc 7 to rotate and grind and chamfer the oil-impregnated bearing.

[0038] The working principle and usage process of this utility model are as follows: When using the oil-impregnated bearing chamfering device, install the device in a suitable position, place the oil-impregnated bearing on the worktable 1, turn on the electric push rod 8 to move the arc-shaped clamping plate 9 to clamp and fix the oil-impregnated bearing, then the cylinder 5 pushes the motor 6 to move downward, and at the same time the grinding disc 7 on the lower side of the motor 6 moves downward, so that the end face of the oil-impregnated bearing enters the grinding groove 10. Turn on the motor 6 to drive the grinding disc 7 to rotate and grind and chamfer the oil-impregnated bearing. After setting the cleaning component 2, the chamfered oil-impregnated bearing is removed from the worktable 1. Then, turn on the motor 23 to drive the lead screw 24 to rotate. The screw 24 rotates, causing the moving plate 25 to move within the folding plate 21. The movement of the moving plate 25, via the connecting frame 26, pushes the scraper 27 forward. The scraper 27 pushes the debris from the oil-impregnated bearing placement area on the worktable 1 forward, causing the debris to fall through the rectangular groove 22. The cleaning component 2 automatically cleans the oil-impregnated bearing placement area on the worktable 1, preventing debris from affecting the stability of subsequent bearing placement. The collection component 28 allows the handheld collection box 282 to be placed into the placement groove 284 of the fixed plate 281. The rotating plate 285 limits the collection box 282, which can collect the waste falling from the rectangular groove 22. The collection component 28 can centrally collect the cleaned waste. When installing the grinding disc 7, the upper insert plate 32 of the grinding disc 7 is inserted into the slot 33 at the lower end of the fixing base 31. Then, the fixing bolt 34 is inserted into the through hole 36 of the fixing base 31, and one end of the fixing bolt 34 is screwed into the fixing hole 35 of the insert plate 32, achieving the effect of limiting and fixing the insert plate 32 and the grinding disc 7. The connecting component 3 can be used to connect the grinding disc 7. Disassembly and replacement are performed to avoid wear and tear on the grinding disc 7 over a long period of use, which would affect the subsequent chamfering quality. By setting a clamping component 37, when the cylinder 5 pushes the grinding disc 7 to clamp the oil-impregnated bearing, the cylinder 5 continues to push the grinding disc 7 downward. At the same time, the sliding column 373 at the upper end of the motor 6 pushes the sliding plate 372 to move in the fixed frame 371. The movement of the sliding plate 372 compresses the spring 375 on the fixed rod 374. The spring 375 can be used to clamp the grinding disc 7 to the oil-impregnated bearing. By setting a clamping component 37, the contact between the grinding disc 7 and the oil-impregnated bearing can be buffered and protected, avoiding excessive downward movement of the grinding disc 7 and causing pressure damage to the oil-impregnated bearing.
