Description

Technical Field

[0001] The invention belongs to the technical field of polishing, and more specifically, particularly relates to a polishing device for machining a motor end cover. Background Art

[0002] A polishing device for motor end cover processing is a device specially used for polishing motor end covers. It is mainly composed of a polishing mechanism, a clamping mechanism and a control system. The polishing mechanism usually includes a polishing wheel and a drive motor, which can efficiently remove surface defects of the end cover and achieve the required finish. The clamping mechanism can stably fix motor end covers of different sizes and shapes. The control system accurately controls the speed of the polishing wheel, the clamping action, etc. The device has many advantages, which can greatly improve the processing efficiency and save manpower and time costs; ensure uniform processing quality and improve product appearance performance; have strong adaptability and can meet different production needs; easy to operate, with a simple and easy-to-understand operation interface, and operators can get started after simple training.

[0003] However, during the implementation of the above technical solution, it was found that there were at least the following technical problems:

[0004] 1. When polishing the motor end cover, the polishing paste is generally applied with a thickness of 0.5 mm to 1 mm. Before polishing the motor end cover, the staff needs to apply polishing paste to the motor end cover. When applying the polishing paste, the staff may apply uneven force, so some areas may be over-applied with polishing paste, while other areas may be over-applied with polishing paste due to excessive polishing paste, making the surface rough or scratched, while other areas cannot effectively remove surface defects due to insufficient polishing paste, resulting in insufficient finish, which not only affects the appearance quality of the motor end cover, but may also affect its performance and service life.

[0005] 2. If the polishing paste coating device is too close to the polishing device, the coating device and the polishing device may collide due to the vibration of the equipment, improper operation, etc., which may not only damage the equipment, but also cause accidents and threaten the safety of the staff.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] In the present invention, the staff moves the polishing paste storage tank into the motor end cover body, and then starts motor 2. When motor 2 rotates, it will drive the corresponding sprocket to rotate. Both sprockets are engaged with the synchronous chain, so the two sprockets drive the corresponding rotating columns to rotate, and the two rotating columns drive the two threaded rods to rotate. The moving disk is engaged with the corresponding threaded rod and does not rotate, so the moving disk moves vertically downward. Polishing paste is stored in the polishing paste storage tank, so when the moving disk descends, the polishing paste will be squeezed out of the groove hole to achieve the purpose of applying the polishing paste. The extrusion amount of the polishing paste is accurately controlled by motor 2, thereby improving the quality and effect of polishing.

[0015] In the present invention, when the motor 2 is started, the motor 1 is started at the same time. The motor 1 drives the long rod to rotate counterclockwise. Since the motor 1 is connected to the long rod through the connecting column, and the long rod is connected to the connecting plate 2 at the lower end through the damping ring, when the motor 1 is started, the connecting plate 2 at the lower end starts to rotate. The connecting plate 2 is fixedly connected to the polishing paste storage tank, so the two polishing paste storage tanks will also rotate synchronously, so that the polishing paste storage tanks can be rotated while squeezing out the polishing paste, so that the inner wall of the motor end cover body can be coated with the polishing paste. Through the rotation of the polishing paste storage tank, the inner wall of the motor end cover body can be contacted with the polishing paste in a larger range, which increases the contact opportunity between the polishing paste and the inner wall of the motor end cover, and improves the coverage rate of the polishing paste coating to a certain extent.

[0016] In the present invention, when the inner wall of the motor end cover body is completely covered with polishing paste, the motor 1 is controlled to output in the reverse direction, and the polishing paste storage tank rotates in the reverse direction. When the arc block 1 corresponds to the position of the two slots, the spring 2 rebounds and pushes the moving block 2 and the arc block 1 to rise, so that the arc block 1 is against the two polishing paste storage tanks and cannot rotate. Since the long rod is connected to the damping ring, the motor 1 can drive the long rod to rotate normally. At this time, the two rotating bevel gears drive the meshing bevel gear to rotate synchronously, and the meshing bevel gear drives the threaded rod 2 to rotate. Since the moving long block does not rotate, Moving the long block will drive the arc surface block 2 to move to the left until it moves to the appropriate position, and the arc surface block 2 maintains a suitable distance from the inner wall of the motor end cover body. At this time, the motor 1 is controlled to output in the forward direction, and the two polishing paste storage tanks rotate again, and the arc surface block 2 will also rotate. The arc surface block 2 will scratch the overly thick polishing paste when rotating, and can adjust the uneven polishing paste on the inner wall of the motor end cover body. Through the scratching effect of the arc surface block 2, the thickness of the polishing paste is made more uniform, providing more consistent working conditions for the subsequent polishing process, thereby improving the quality and effect of polishing.

[0017] In the present invention, the two connecting plates are located between the two polishing paste storage tanks, and the polishing paste storage tanks are located at the upper and lower ends, so that the long rod is in a closed space, which prevents dust or impurities from splashing into the two polishing paste storage tanks when the motor end cover body is polished and affecting the meshing between the rotating bevel gear and the meshing bevel gear. This design can effectively protect the meshing transmission between the rotating bevel gear and the meshing bevel gear, and ensure the stability and reliability of the device during operation.

[0018] In the present invention, by providing a limit plate, when the movable long block moves to the left, the distance between the arc surface block 2 and the inner wall of the motor end cover body can be controlled by stopping the output of the motor 1, so that the thickness of the polishing paste can be adjusted freely within .mm to mm, thereby improving the adaptability of the polishing paste application.

[0019] In the present invention, after the polishing paste is applied to the motor end cover body, the staff picks up the connecting plate 1 along the track of the T-slot. When the connecting plate 1 rises to a certain distance, the spring 1 pushes the moving block 1 to move, so that the connecting plate 1 can be stably placed at the upper end position of the T-slot. At this time, the staff pushes the connecting plate 1 to move it to the edge of the cross plate, so that the subsequent polishing process is not affected. This design facilitates the staff to move and adjust the relevant parts after the polishing paste is applied to the motor end cover body, thereby improving the convenience and flexibility of operation.

[0031] The following embodiments of the present invention are described in further detail in conjunction with the accompanying drawings and examples. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0032] See also Figure 1-Figure 10The present invention provides a polishing device for processing a motor end cover, comprising a device body 11, a base 12 is fixedly connected to the lower surface of the device body 11, a workbench 13 is fixedly connected to the lower surface of the base 12, a motor end cover body 19 is arranged on the workbench 13, the motor end cover processing polishing device is also provided with a polishing paste collecting device, comprising a moving long block 39, an arc surface block 254 and two polishing paste storage tanks 35, the side surfaces of the two polishing paste storage tanks 35 are each provided with a group of slots, the upper surface of the base 12 is fixedly connected to two support frames 14, the workbench 13 is located between the two support frames 14, the upper surfaces of the two support frames 14 are fixedly connected to a transverse plate 15, the opposite sides of the two transverse plates 15 are each provided with a T-slot 16, a connecting plate 17 is arranged between the two T-slots 16, and both ends of the connecting plate 17 are fixedly connected to a fixing plate 25, the two Both ends of a fixed plate 25 are movably connected with a moving block 22, and each moving block 22 is located inside the corresponding T-slot 16. The staff moves the polishing paste storage tank 35 into the motor end cover body 19, and then starts the motor 2 33. When the motor 2 33 rotates, it will drive the corresponding sprocket 38 to rotate. The two sprockets 38 are engaged with the synchronous chain 37, so the two sprockets 38 drive the corresponding rotating columns 36 to rotate, and the two rotating columns 36 drive the two threaded rods 42 to rotate. The moving disk 43 is engaged with the corresponding threaded rod 42 and does not rotate, so the moving disk 43 will move vertically downward. Polishing paste is stored in the polishing paste storage tank 35, so when the moving disk 43 descends, the polishing paste will be squeezed out from the slot hole to achieve the purpose of applying the polishing paste. The extrusion amount of the polishing paste is accurately controlled by the motor 2 33, thereby improving the quality and effect of polishing.

[0033] Each moving block 22 has an internal hollow structure, and a spring 21 is fixedly connected to the interior of each moving block 22. One end of each spring 21 is fixedly connected to a push plate 23, and one end of each push plate 23 is fixedly connected to a fixing column 24. Each fixing column 24 passes through the moving block 22 and is fixedly connected to the corresponding fixing plate 25. A hole 20 is penetrated through the upper end side of the connecting plate 17, and the connecting plate 17 is fixedly connected to the motor 18 through the hole 20. The output port of the motor 18 is fixedly connected to the connecting column 26. Two polishing paste storage tanks 35 are both located inside the motor end cover body 19. When the motor 33 is started, the motor 18 is started at the same time. The motor 18 drives the long rod 41 to rotate counterclockwise. Since the motor 18 is connected to the long rod 41 through the connecting column 26, and the long rod 41 is connected to the connecting plate 2 40 at the lower end through the damping ring 51, when the motor 18 is started, the connecting plate 2 40 at the lower end begins to rotate. The connecting plate 2 40 is fixedly connected to the polishing paste storage tank 35, so the two polishing paste storage tanks 35 will also rotate synchronously, so that the polishing paste storage tank 35 can squeeze out the polishing paste while rotating, so that the inner wall of the motor end cover body 19 can be coated with the polishing paste. Through the rotation of the polishing paste storage tank 35, the inner wall of the motor end cover body 19 can be exposed to the polishing paste in a larger range, thereby increasing the contact opportunity between the polishing paste and the inner wall of the motor end cover, and improving the coverage rate of the polishing paste to a certain extent.

[0034] A rectangular groove 27 is provided on the lower surface of the motor end cover body 19. The two rectangular grooves 27 correspond to the positions of the two polishing paste storage tanks 35. A fixed column 2 32 is provided in the two rectangular grooves 27. The lower surfaces of the two fixed columns 2 32 are fixedly connected to the inner wall of the motor end cover body 19. The motor end cover body 19 is movably connected to two moving blocks 28 through the two rectangular grooves 27. The two moving blocks 28 are both hollow structures. The insides of the two moving blocks 28 are fixedly connected to springs 2 30. The lower surfaces of the two springs 2 30 are fixedly connected to Push plate 2 31, the upper surfaces of the two fixed pillars 2 32 are fixedly connected to the lower surfaces of the corresponding push plate 2 31, and the two fixed pillars 2 32 pass through the corresponding moving block 28, the upper surfaces of the two moving blocks 28 are fixedly connected with the arc surface block 1 29, the arc surfaces of the two arc surface blocks 1 29 are opposite, and the lower ends of the two polishing paste storage tanks 35 are provided with slots corresponding to the arc surface block 1 29. When the inner wall of the motor end cover body 19 is completely covered with polishing paste, the motor 18 is controlled to output in the reverse direction. At this time, the polishing paste storage tank 35 rotates in the reverse direction. When the arc surface block 1 When the positions of the two grooves 29 correspond to each other, the spring 2 30 rebounds and pushes the moving block 28 and the arc surface block 1 29 up, so that the arc surface block 1 29 is pressed against the two polishing paste storage tanks 35 and cannot rotate. Since the long rod 41 is connected to the damping ring 51, the motor 18 can normally drive the long rod 41 to rotate. At this time, the two rotating bevel gears 50 drive the meshing bevel gear 52 to rotate synchronously, and the meshing bevel gear 52 drives the threaded rod 2 53 to rotate. Since the moving long block 39 does not rotate, the moving long block 39 will drive the arc surface block 2 54 to move left, until When it moves to the appropriate position, the arc surface block 2 54 maintains an appropriate distance from the inner wall of the motor end cover body 19. At this time, the motor 18 is controlled to output in the forward direction, the two polishing paste storage tanks 35 rotate again, and the arc surface block 2 54 also rotates. The arc surface block 2 54 will scratch the overly thick polishing paste when rotating, and can adjust the uneven polishing paste on the inner wall of the motor end cover body 19. Through the scratching effect of the arc surface block 2 54, the thickness of the polishing paste is made more uniform, providing more consistent working conditions for the subsequent polishing process, thereby improving the quality and effect of polishing.

[0035] The interiors of the two polishing paste storage tanks 35 are both rotatably connected with threaded rods 42, and movable disks 43 are arranged inside the two polishing paste storage tanks 35. The upper ends of the two movable disks 43 are penetrated with threaded holes 44, and the two threaded rods 42 are threadedly sleeved with the corresponding movable disks 43 through the threaded holes 44. The upper ends of the two polishing paste storage tanks 35 are both rotatably connected with rotating columns 36, and the lower surfaces of the rotating columns 36 are fixedly connected with the upper surfaces of the corresponding threaded rods 42, and the rotating columns 36 pass through the polishing paste storage tanks 35. The two rotating columns 36 A sprocket 38 is fixedly connected, and a synchronous chain 37 is arranged between the two sprockets 38. Both ends of the synchronous chain 37 are meshed and connected with the corresponding sprockets 38. The two connecting plates 40 are located between the two polishing paste storage tanks 35, and the polishing paste storage tanks 35 are located at the upper and lower ends, so that the long rod 41 is in a closed space, which prevents dust or impurities from splashing into the two polishing paste storage tanks 35 when the motor end cover body 19 is polished, affecting the meshing between the rotating bevel gear 50 and the meshing bevel gear 52. This design can effectively protect the meshing transmission between the rotating bevel gear 50 and the meshing bevel gear 52, and ensure the stability and reliability of the device during operation.

[0036] The upper surface of the polishing paste storage tank 35 located at the rear end of the connecting plate 2 40 is fixedly connected with a U-shaped plate 34, and the upper end position of the U-shaped plate 34 is fixedly connected with a motor 2 33, and the output port of the motor 2 33 is fixedly connected to the upper surface of the rotating column 36 at the rear end, and a fixed plate 2 46 is arranged between the two polishing paste storage tanks 35, and both ends of the fixed plate 2 46 are fixedly connected to the corresponding polishing paste storage tanks 35, and two connecting plates 2 40 are arranged between the two polishing paste storage tanks 35, and the two connecting plates 2 40 are placed vertically and parallel to each other, and the front and rear ends of the two connecting plates 2 40 are fixedly connected to the corresponding polishing paste storage tanks 35, and a long rod 41 is arranged between the two connecting plates 2 40, and the connecting plate 2 40 at the lower end is rotatably connected with a damping ring 51, and the damping ring The upper surface of 51 is fixedly connected to the lower surface of the long rod 41, and the connecting column 26 is fixedly connected to the upper surface of the long rod 41 through the connecting plate 2 40 located at the upper end, and two rotating bevel gears 50 are fixedly connected to the long rod 41, and the left ends of the two rotating bevel gears 50 are vertically meshed with the meshing bevel gears 52, and the fixed plate 2 46 is rotatably connected with two rotating short columns 45 corresponding to the positions of the meshing bevel gears 52, and the sides of the two rotating short columns 45 are fixedly connected with the threaded rod 2 53. When the moving long block 39 moves to the left, the distance between the arc block 2 54 and the inner wall of the motor end cover body 19 can be controlled by stopping the output of the motor 18, so that the thickness of the polishing paste can be adjusted arbitrarily within 0.5 mm to 1 mm, thereby improving the adaptability of the polishing paste application.

[0037] A movable long block 39 is arranged at the left end of the fixed plate 2 46, and a curved surface block 2 54 is fixedly connected to the side of the movable long block 39, grooves 49 are provided at both the front and rear ends of the movable long block 39, and the movable long block 39 is threadedly sleeved with two threaded rods 2 53, and a fixed column 3 48 is fixedly connected to the side of the fixed plate 2 46, and a cylindrical groove is arranged inside the movable long block 39, and a limit plate 47 is movably sleeved inside the movable long block 39, and the fixed column 3 48 passes through the movable long block 39 and is fixedly connected to a side of the limit plate 47 facing the fixed column 3 48, when the motor end cover body 1 After the polishing paste is applied, the staff member picks up the connecting plate 17 along the track of the T-slot 16. When the connecting plate 17 rises to a certain distance, the spring 21 pushes the moving block 22 to move, so that the connecting plate 17 can be stably placed at the upper end of the T-slot 16. At this time, the staff member pushes the connecting plate 17 to move it to the edge of the horizontal plate 15, so that the subsequent polishing process is not affected. This design facilitates the staff member to move and adjust the relevant parts after the polishing paste is applied to the motor end cover body, improving the convenience and flexibility of operation.

[0038] Working principle:

[0039] In the first step, the staff moves the polishing paste storage tank 35 into the motor end cover body 19, and then starts the motor 2 33. When the motor 2 33 rotates, it will drive the corresponding sprocket 38 to rotate. Both sprockets 38 are engaged with the synchronous chain 37, so the two sprockets 38 drive the corresponding rotating columns 36 to rotate, and the two rotating columns 36 drive the two threaded rods 1 42 to rotate. The moving disk 43 is engaged with the corresponding threaded rod 1 42 and does not rotate, so the moving disk 43 will move vertically downward. Polishing paste is stored in the polishing paste storage tank 35, so when the moving disk 43 descends, the polishing paste will be squeezed out of the groove hole to achieve the purpose of applying the polishing paste. The extrusion amount of the polishing paste is accurately controlled by the motor 2 33, thereby improving the quality and effect of polishing.

[0040] In the second step, when the motor 2 33 is started, the motor 1 18 is started at the same time. The motor 1 18 drives the long rod 41 to rotate counterclockwise. Since the motor 1 18 is connected to the long rod 41 through the connecting column 26, and the long rod 41 is connected to the connecting plate 2 40 at the lower end through the damping ring 51, when the motor 1 18 is started, the connecting plate 2 40 at the lower end begins to rotate, and the connecting plate 2 40 is fixedly connected to the polishing paste storage tank 35. Therefore, the two polishing paste storage tanks 35 will also rotate synchronously, so that the polishing paste storage tank 35 can squeeze out the polishing paste while rotating, so that the inner wall of the motor end cover body 19 can be coated with the polishing paste. Through the rotation of the polishing paste storage tank 35, the inner wall of the motor end cover body 19 can be in contact with the polishing paste in a larger range, which increases the contact opportunity between the polishing paste and the inner wall of the motor end cover, and improves the coverage rate of the polishing paste to a certain extent.

[0041] In the third step, when the inner wall of the motor end cover body 19 is completely covered with the polishing paste, the motor 18 is controlled to output in the reverse direction. At this time, the polishing paste storage tank 35 rotates in the reverse direction. When the arc block 1 29 corresponds to the position of the two slots, the spring 2 30 rebounds and pushes the moving block 28 and the arc block 1 29 to rise, so that the arc block 1 29 is against the two polishing paste storage tanks 35 and cannot rotate. Since the long rod 41 is connected to the damping ring 51, the motor 18 can normally drive the long rod 41 to rotate. At this time, the two rotating bevel gears 50 drive the meshing bevel gear 52 to rotate synchronously, and the meshing bevel gear 52 drives the threaded rod 2 53 to rotate. It does not rotate, so the moving long block 39 will drive the arc surface block 2 54 to move to the left until it moves to the appropriate position. The arc surface block 2 54 maintains a suitable distance from the inner wall of the motor end cover body 19. At this time, the motor 18 is controlled to output in the forward direction, and the two polishing paste storage tanks 35 rotate again. The arc surface block 2 54 will also rotate. The arc surface block 2 54 will scratch the overly thick polishing paste when rotating, and can adjust the uneven polishing paste on the inner wall of the motor end cover body 19. Through the scratching effect of the arc surface block 2 54, the thickness of the polishing paste is made more uniform, providing more consistent working conditions for the subsequent polishing process, thereby improving the quality and effect of polishing.

[0042] In the fourth step, the two connecting plates 40 are located between the two polishing paste storage tanks 35, and the polishing paste storage tanks 35 are located at the upper and lower ends, so that the long rod 41 is in a closed space, which prevents dust or impurities from splashing into the two polishing paste storage tanks 35 when the motor end cover body 19 is polished to affect the meshing between the rotating bevel gear 50 and the meshing bevel gear 52. This design can effectively protect the meshing transmission between the rotating bevel gear 50 and the meshing bevel gear 52, and ensure the stability and reliability of the device during operation.

[0043] The fifth step is to provide a limit plate 47. When the movable long block 39 moves to the left, the distance between the arc block 2 54 and the inner wall of the motor end cover body 19 can be controlled by stopping the output of the motor 18, so that the thickness of the polishing paste can be adjusted freely within 0.5 mm to 1 mm, thereby improving the adaptability of the polishing paste application.

[0044] The sixth step, when the motor end cover body 19 is coated with the polishing paste, the staff picks up the connecting plate 17 along the track of the T-slot 16. When the connecting plate 17 rises to a certain distance, the spring 21 pushes the moving block 22 to move, so that the connecting plate 17 can be stably placed at the upper end position of the T-slot 16. At this time, the staff pushes the connecting plate 17 to move it to the edge of the cross plate 15, so that the subsequent polishing process is not affected. This design facilitates the staff to move and adjust the relevant parts after the polishing paste is coated on the motor end cover body, thereby improving the convenience and flexibility of operation.
