Description

Technical Field

[0001] The utility model relates to the technical field of clutch cleaning equipment, and specifically relates to a cleaning equipment for clutch production. Background Technique

[0002] A clutch is installed between the driving shaft and the driven shaft, inside the flywheel housing between the engine and the gearbox, and is a device used to separate or engage the rotational motion of the two shafts. After the production of the clutch facings, there are impurities and oil stains on them, and a cleaning equipment is needed to clean the clutch facings.

[0003] In the patent application with the authorization publication number CN219112359U, the authorization publication date of June 3, 2023, and the name "A Cleaning Device for Automobile Clutch Facings Production", it includes a cleaning tank. A reduction motor is provided on one side of the cleaning tank. The output end of the reduction motor extends into the cleaning tank and is connected with a screen flat cylinder. A cover body is hinged at the opening of the screen flat cylinder, and a lock body is provided on the cover body. An ultrasonic generator and a filtering device are provided at the bottom of the cleaning tank. The output end of the ultrasonic generator is connected with a transducer arranged inside the cleaning tank. The water inlet end of the filtering device is communicated with the cleaning tank through a pipeline one. The output end of the filtering device is communicated with a water pump. The output end of the water pump is provided with a pipeline two communicated with the cleaning tank.

The advantages of this utility model are: the cleaning efficiency of automobile clutch facings is high, and the corners of automobile clutch facings can also be cleaned more thoroughly.

[0004] When the existing cleaning equipment for clutch production is in use, although the cleaning method by ultrasonic waves makes the cleaning efficiency of automobile clutch facings high, and the corners of automobile clutch facings can also be cleaned more thoroughly, it is found in actual use that when this cleaning equipment is in use, the workpiece needs to be placed in the screen flat cylinder first.

[0016] 3. Beneficial effects:

[0017] Adopting the technical solution provided by the present invention, compared with the prior art, the cleaning equipment for clutch production of the present invention has the following specific contents:

[0018] (1) The electric mechanism drives the turntable to rotate, so that the turntable drives the clamping seat and the structures thereon to rotate synchronously. When the ejector rod rotates against the convex block, the convex block pushes the transmission frame towards the clamping seat through the ejector rod. Cooperating with the transmission groove and the transmission rod of the transmission frame, the transmission frame drives the clamping frames to approach each other. At the same time, a workpiece is placed between the clamping frames manually or by a robotic arm. The clamping frames clamp the workpiece through the clamping rods. Then, the turntable drives the clamped workpiece into the cleaning tank. The ultrasonic generator and the oscillator transducer drive the cleaning liquid in the cleaning tank to vibrate at high frequency to clean the impurities and oil stains on the surface of the workpiece. When the turntable continues to rotate and the ejector rod is misaligned with the convex block, the transmission frame is reset by the return spring, and the clamping frames move away from each other to automatically release the workpiece. The workpiece can be taken off manually or by a robotic arm. Through this cleaning device, when the turntable rotates, the clamping mechanism on it can automatically clamp or release the workpiece, so as to continuously clean the workpiece, effectively improving the cleaning efficiency of the workpiece.

[0019] (2) When clamping the workpiece through the clamping rod, the clamping rod contacts the workpiece through the rubber soft head, which can not only protect the workpiece, but also reduce the contact area with the workpiece through the hemispherical rubber soft head, thereby reducing the clamping area of the workpiece, so as to improve the cleaning effect of the workpiece.

Among them,

[0030] On the top of the longer side of the cleaning tank 1, brackets 4 are symmetrically and fixedly connected. A fixed wheel 5 is arranged between the brackets 4. Both ends of the fixed wheel 5 are fixedly connected to the brackets 4 through a fixed shaft 6. On both sides of the fixed wheel 5, turntables 7 are symmetrically arranged. The turntables 7 are rotationally connected to the fixed shaft 6. The turntables 7 are driven by an electric mechanism to rotate. Between the turntables 7, clamping seats 11 are fixedly connected at equal intervals. A convex block 12 is fixedly connected to the lower half circle of the fixed wheel 5. On both sides of the clamping seat 11, sliding grooves 13 are symmetrically opened. A sliding block 14 is arranged in the sliding grooves 13. On one side of the clamping seat 11 close to the fixed wheel 5, a transmission frame 15 is arranged. On both sides of the transmission frame 15, rod grooves 16 are symmetrically opened. On both sides of the transmission frame 15 corresponding to the rod grooves 16, transmission grooves 17 are symmetrically opened;

[0031] A rod 18 is fixedly connected to the sliding block 14 corresponding to the position of the rod groove 16. On both sides of the rod 18 corresponding to the transmission groove 17, transmission rods 19 are symmetrically fixedly connected. On the side of the sliding block 14 away from the rod 18, a clamping frame 20 is fixedly connected. On the inner side of the clamping frame 20, clamping rods 21 are fixedly connected at equal intervals. On one side of the clamping seat 11 corresponding to the transmission frame 15, a fixed rod 23 is fixedly connected. At one end of the fixed rod 23 close to the transmission frame 15, a guiding groove 24 is opened. On one side of the transmission frame 15 corresponding to the guiding groove 24, a guiding rod 25 is fixedly connected. A return spring 26 is sleeved on the outer side of the fixed rod 23 between the clamping seat 11 and the transmission frame 15. On one side of the transmission frame 15 close to the fixed wheel 5, a top rod 27 is fixedly connected. The cleaning liquid in the cleaning tank 1 is recycled through a circulation mechanism;

[0032] The turntable 7 is driven to rotate by an electric mechanism, so that the turntable 7 drives the clamping seat 11 and the structures thereon to rotate synchronously. When the ejector rod 27 abuts against the convex block 12 through rotation, the convex block 12 pushes the transmission frame 15 to move towards the clamping seat 11 through the ejector rod 27. In cooperation with the transmission groove 17 of the transmission frame 15 and the transmission rod 19, the transmission frame 15 drives the clamping frames 20 to approach each other. At the same time, a workpiece is placed between the clamping frames 20 manually or by a robotic arm, and the clamping frames 20 clamp the workpiece through the clamping rods 21. Then, the turntable 7 drives the clamped workpiece into the cleaning tank 1, and the ultrasonic generator 2 and the oscillator transducer 3 drive the cleaning liquid in the cleaning tank 1 to vibrate at a high frequency to clean the impurities and oil stains on the surface of the workpiece. When the turntable 7 continues to rotate and the ejector rod 27 is misaligned with the convex block 12, the transmission frame 15 is reset by the return spring 26, and the clamping frames 20 move away from each other to automatically release the workpiece, and then the workpiece can be taken off manually or by a robotic arm. Through this cleaning device, when the turntable 7 rotates, the clamping mechanism thereon can automatically clamp or release the workpiece, so as to continuously clean the workpiece, effectively improving the cleaning efficiency of the workpiece.

[0033] Please refer to Figures 1 to 4 As shown in the figure, the electric mechanism includes a motor 8. The motor 8 is installed at the top of the bracket 4. A first gear 9 is installed at the shaft end of the motor 8. A second gear 10 is fixedly connected to the outside of the turntable 7 corresponding to the first gear 9. When it is necessary to drive the turntable 7 to rotate, the motor 8 drives the first gear 9 to rotate. The first gear 9 drives the second gear 10 to rotate through meshing, so that the second gear 10 drives the turntable 7 to rotate through fixed connection. The transmission grooves 17 on both sides of the transmission frame 15 are distributed in a figure-eight shape, and the inner width of the transmission groove 17 matches the outer diameter of the transmission rod 19. When the transmission frame 15 moves towards the clamping seat 11, the transmission grooves 17 in the figure-eight shape drive the support rods 18 to approach each other through the transmission rod 19, and the support rods 18 drive the clamping frames 20 to approach each other through the sliding blocks 14. When the transmission frame 15 moves away from the clamping seat 11, the clamping frames 20 are driven to move away from each other, so as to drive the clamping frames 20 to approach or move away from each other through the movement of the transmission frame 15.

[0034] Please refer to Figures 1 to 4, a rubber soft head 22 is fixedly connected to the end of the clamping rod 21 away from the clamping bracket 20 by gluing. The rubber soft head 22 is hemispherical. When the workpiece is clamped by the clamping rod 21, the clamping rod 21 contacts the workpiece through the rubber soft head 22. It can not only protect the workpiece, but also reduce the contact area with the workpiece through the hemispherical rubber soft head 22, thereby reducing the clamping area of the workpiece, so as to improve the cleaning effect of the workpiece. The guide rod 25 is rectangular columnar, and the external dimensions of the guide rod 25 match the internal dimensions of the guide groove 24. When the transmission frame 15 moves, the movement of the transmission frame 15 is guided by the guide rod 25 and the guide groove 24 to prevent the movement of the transmission frame 15 from shifting.

[0035] Please refer to Figures 1 to 4 , the circulation mechanism includes a filter tank 28. The filter tank 28 is arranged on the outer side of the cleaning tank 1 away from the ultrasonic generator 2. A filter screen 29 is installed inside the filter tank 28 near the upper part. The filter tank 28 below the filter screen 29 is connected to one side near the bottom of the cleaning tank 1 through a connecting pipe 30. A water pump 31 is installed on the top of the filter tank 28. The water pump 31 is connected to the filter tank 28 above the filter screen 29 through a water suction pipe 32. The water pump 31 is connected to the cleaning tank 1 through a water injection pipe 33. A sewage outlet 34 is opened on one side near the bottom of the cleaning tank 1. The opening of the sewage outlet 34 is sealed by a sealing plug 35. When the workpiece enters the cleaning tank 1 for cleaning, impurities precipitate to the bottom of the cleaning tank 1. The sewage at the bottom of the cleaning tank 1 enters the filter tank 28 through the connecting pipe 30. The sewage is filtered by the filter screen 29, so that the impurities precipitate at the bottom of the filter tank 28. The filtered cleaning liquid is re-injected into the cleaning tank 1 through the water pump 31. When it is necessary to clean the impurities inside the filter tank 28, the sewage outlet 34 is opened by the sealing plug 35, and the impurities inside the filter tank 28 can be discharged through the sewage outlet 34. Through this circulation mechanism, the cleaning liquid in the cleaning tank 1 can be filtered and recycled, so as to achieve the purpose of saving water.

[0036] Working principle: When using the cleaning equipment for clutch production, such as Figures 1 to 4As shown in the figure, first, when the turntable 7 needs to be driven to rotate, the motor 8 drives the first gear 9 to rotate. The first gear 9 drives the second gear 10 to rotate through meshing, so that the second gear 10 drives the turntable 7 to rotate through fixed connection, and the turntable 7 drives the clamping seat 11 and the structures thereon to rotate synchronously. When the ejector rod 27 abuts against the convex block 12 through rotation, the convex block 12 pushes the transmission frame 15 to move towards the clamping seat 11 through the ejector rod 27. In cooperation with the transmission groove 17 of the transmission frame 15 and the transmission rod 19, the transmission frame 15 drives the clamping frames 20 to approach each other. At the same time, the workpiece is placed between the clamping frames 20 manually or by a robotic arm, and the clamping frames 20 clamp the workpiece through the clamping rods 21. Then, the turntable 7 drives the clamped workpiece into the cleaning tank 1, and the ultrasonic generator 2 and the oscillator transducer 3 drive the cleaning liquid in the cleaning tank 1 to vibrate at high frequency to clean the impurities and oil stains on the surface of the workpiece. When the turntable 7 continues to rotate and the ejector rod 27 is displaced from the convex block 12, the transmission frame 15 is reset by the return spring 26, and the clamping frames 20 move away from each other to automatically release the workpiece, and the workpiece can be taken off manually or by a robotic arm. Through this cleaning device, when the turntable 7 rotates, the clamping mechanism thereon can automatically clamp or release the workpiece, so as to continuously clean the workpiece, effectively improving the cleaning efficiency of the workpiece;

[0037] When clamping the workpiece through the clamping rod 21, the clamping rod 21 contacts the workpiece through the rubber soft head 22, which can not only protect the workpiece, but also reduce the contact area with the workpiece through the hemispherical rubber soft head 22, thereby reducing the clamping area of the workpiece, so as to improve the cleaning effect of the workpiece. When the workpiece enters the cleaning tank 1 for cleaning, the impurities precipitate to the bottom of the cleaning tank 1, and the sewage at the bottom of the cleaning tank 1 enters the filter tank 28 through the connecting pipe 30. The sewage is filtered through the filter screen 29, so that the impurities precipitate at the bottom of the filter tank 28. The filtered cleaning liquid is re-injected into the cleaning tank 1 through the water pump 31. When it is necessary to clean the impurities inside the filter tank 28, the drain port 34 is opened through the sealing plug 35, and the impurities inside the filter tank 28 can be discharged through the drain port 34. Through this circulation mechanism, the cleaning liquid in the cleaning tank 1 can be filtered and recycled, thereby achieving the purpose of saving water.

Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
