Description

Technical Field

[0001] This utility model relates to the field of speed reducer processing technology, specifically a polishing device for speed reducer processing. Background Technology

[0002] In the manufacturing process of speed reducers, polishing is a crucial step in improving the surface finish, precision, and wear resistance of parts. The performance of the polishing equipment directly affects the processing quality and production efficiency of speed reducer components. Currently, commonly available polishing equipment for speed reducer processing generally faces the problem of excessively high polishing disc temperatures during operation. Existing polishing devices generate a lot of heat during operation due to high-speed friction between the polishing disc and the surface of the reducer parts. However, most devices are not equipped with a proper cooling structure. As a result, the temperature of the polishing disc will continue to rise as the polishing operation continues. When the temperature exceeds a certain threshold, the material properties of the polishing disc will change, leading to deformation, accelerated wear, and other issues, which will significantly shorten its service life. Therefore, we propose a polishing device for reducer processing. Utility Model Content

[0003] To address the shortcomings of existing technologies, the purpose of this utility model is to provide a polishing device for speed reducer processing, which has the advantage of auxiliary cooling. This solves the problem that existing polishing devices generate a lot of heat during high-speed friction between the polishing disc and the surface of speed reducer parts, and most devices are not equipped with a complete cooling structure. In this case, the temperature of the polishing disc will continue to rise as the polishing operation continues. When the temperature exceeds a certain threshold, the material properties of the polishing disc will change, resulting in deformation, accelerated wear, and other problems, which will significantly shorten its service life.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a polishing device for speed reducer processing, comprising a worktable, a bracket fixedly connected to the right side of the top of the worktable, a first motor fixedly connected to the top of the bracket, a drive shaft fixedly connected to the output end of the first motor, a housing fixedly connected to the surface of the drive shaft, a second motor fixedly connected to the front side of the top of the housing, a rotating shaft fixedly connected to the output end of the second motor, connecting shafts movably connected to both sides of the inner cavity of the housing, a polishing disc fixedly connected to the bottom of the connecting shaft, an electric telescopic rod fixedly connected to the right side of the bottom of the worktable, and a water tank fixedly connected to the top of the electric telescopic rod.

[0005] Preferably, a connecting frame is fixedly connected to the left side of the bottom of the workbench, and an electric cylinder is movably connected to the bottom of the inner surface of the connecting frame via a first bearing. A fixing frame is fixedly connected to the top of the electric cylinder, and support plates are fixedly connected to both sides of the top of the fixing frame. Rectangular plates are fixedly connected to the front and rear sides of the top of the support plates. An electric push rod is fixedly connected to one side of the rectangular plate, and a clamping plate is fixedly connected to one side of the electric push rod.

[0006] Preferably, the top two sides and the bottom two sides of the inner cavity of the housing are movably connected to the connecting shaft through a second bearing, and the bottom two sides of the housing are provided with movable holes.

[0007] Preferably, a first synchronous pulley is fixedly connected to the surface of both the rotating shaft and the connecting shaft, and a first synchronous belt is engaged on the surface of the first synchronous pulley.

[0008] Preferably, each of the four corners of the bottom of the water tank is fixedly connected to a vertical rod, and the surface of the vertical rod is slidably connected to the workbench. A valve is connected to the bottom of the rear side of the water tank.

[0009] Preferably, a second synchronous pulley is fixedly connected to the bottom of the surface of the electric cylinder and the bottom of the drive shaft, and a second synchronous belt is engaged with the surface of the second synchronous pulley.

[0010] Compared with the prior art, this utility model provides a polishing device for speed reducer processing, which has the following beneficial effects: 1. When this utility model is in operation, the second motor is started by the external controller. Through the cooperation of the first synchronous pulley and the first synchronous belt, the connecting shaft will rotate, and the connecting shaft will drive the polishing disc to rotate. First, the material is polished by the polishing disc on the left. After the work is completed, the first motor is started. The first motor will drive the drive shaft to rotate, and the drive shaft will drive the housing to rotate, thereby changing the position of the two polishing discs. Then the polishing work can be carried out again. At this time, the electric telescopic rod can be started. The electric telescopic rod will drive the water tank to rise, thereby moving the polishing disc that needs to be cooled into the inner cavity of the water tank. The water in the inner cavity of the water tank will cool it down, thereby playing an auxiliary cooling role.

[0011] 2. Before polishing, the material is placed on top of the support plate on the right side. Then, the corresponding electric push rod is activated, which moves the clamping plate to hold the material. Then, the electric cylinder is activated, which moves the fixing frame. The fixing frame moves the support plate upward, bringing the material into contact with the polishing disc for polishing. At this time, the operator can place the material to be processed on top of the support plate on the left side and fix it. After polishing, when changing the position of the two polishing discs, the drive shaft drives the electric cylinder to rotate through the cooperation of the second synchronous wheel and the second synchronous belt. This rotates the fixing frame, which in turn rotates the support plate, thus changing the position of the material. The material to be processed is moved to the bottom of the polishing disc, saving loading and unloading time and making the work more efficient. Attached Figure Description

[0017] The specific function of this technical solution is as follows: During operation, the second motor 6 is started by the controller of the external device. Through the cooperation of the first synchronous pulley 9 and the first synchronous belt 10, the connecting shaft 8 will be rotated. The connecting shaft 8 will drive the polishing disc 11 to rotate. First, the material is polished by the polishing disc 11 on the left. After the work is completed, the first motor 3 is started. The first motor 3 will drive the drive shaft 4 to rotate. The drive shaft 4 will drive the housing 5 to rotate, thereby changing the position of the two polishing discs 11. Then the polishing work can be carried out again.

The water in the inner cavity of the water tank 13 will cool it down, thereby playing an auxiliary cooling role. Example

[0018] Based on Embodiment 1, this utility model is as follows: Figure 1 and Figure 2 As shown, a connecting frame 14 is fixedly connected to the left side of the bottom of the workbench 1. An electric cylinder 15 is movably connected to the bottom of the inner surface of the connecting frame 14 via a first bearing. A fixed frame 18 is fixedly connected to the top of the electric cylinder 15. Support plates 19 are fixedly connected to both sides of the top of the fixed frame 18. Rectangular plates 20 are fixedly connected to the front and rear sides of the top of the support plates 19. An electric push rod 21 is fixedly connected to one side of the rectangular plate 20. A clamping plate 22 is fixedly connected to one side of the electric push rod 21. A second synchronous pulley 16 is fixedly connected to the bottom of the surface of the electric cylinder 15 and the bottom of the drive shaft 4. A second synchronous belt 17 is engaged with the surface of the second synchronous pulley 16.

[0019] The specific function of this technical solution is as follows: Before polishing, the material is placed on top of the support plate 19 on the right side. Then, the corresponding electric push rod 21 is activated, which drives the clamping plate 22 to move, thereby clamping the material. Then, the electric cylinder 15 is activated, which drives the fixing frame 18 to move. The fixing frame 18 drives the support plate 19 to rise, thereby bringing the material into contact with the polishing disc 11, and polishing can then be performed. At this time, the operator can place the material to be processed on top of the support plate 19 on the left side and fix it. After polishing is completed, when the positions of the two polishing discs 11 are changed, the drive shaft 4 will drive the electric cylinder 15 to rotate through the cooperation of the second synchronous wheel 16 and the second synchronous belt 17, thereby driving the fixing frame 18 to rotate. The fixing frame 18 drives the support plate 19 to rotate, thereby changing the position of the material, so that the material to be processed moves to the bottom of the polishing disc 11, thus saving the time of loading and unloading, and making the work more efficient.

[0020] Working principle: During operation, the second motor 6 is started by the external controller. Through the cooperation of the first synchronous pulley 9 and the first synchronous belt 10, the connecting shaft 8 is driven to rotate. The connecting shaft 8 drives the polishing disc 11 to rotate. First, the material is polished by the polishing disc 11 on the left. After the work is completed, the first motor 3 is started. The first motor 3 drives the drive shaft 4 to rotate. The drive shaft 4 drives the housing 5 to rotate, thereby changing the position of the two polishing discs 11. Then the polishing work can be carried out again. At this time, the electric telescopic rod 12 can be started. The electric telescopic rod 12 drives the water tank 13 to rise, thereby moving the polishing disc 11 that needs to be cooled into the inner cavity of the water tank 13. The water in the inner cavity of the water tank 13 cools it down, thereby playing an auxiliary cooling role. When the surface of the polishing disc 11 is wet after cooling, the staff can wipe the water stains with a cloth. Before polishing, the material is placed on top of the support plate 19 on the right side. Then, the corresponding electric push rod 21 is activated, which moves the clamping plate 22 to hold the material. Then, the electric cylinder 15 is activated, which moves the fixing frame 18. The fixing frame 18 moves the support plate 19 upward, bringing the material into contact with the polishing disc 11 for polishing. At this time, the worker can place the material to be processed on top of the support plate 19 on the left side and fix it. After polishing, when the positions of the two polishing discs 11 are changed, the drive shaft 4 will drive the electric cylinder 15 to rotate through the cooperation of the second synchronous wheel 16 and the second synchronous belt 17. This will drive the fixing frame 18 to rotate, and the fixing frame 18 will drive the support plate 19 to rotate, thus changing the position of the material and moving it to the bottom of the polishing disc 11. This saves loading and unloading time and makes the work more efficient.
