Description

Technical Field

[0001] The invention belongs to the technical field of coupling production, and in particular relates to an automatic maintenance and cleaning device for couplings. Background Art

[0002] A coupling, also known as a coupling, is a mechanical component used to firmly connect the driving shaft and the driven shaft in different mechanisms so that they rotate together and transmit motion and torque. It is sometimes also used to connect the shaft with other parts.

[0003] After the production of the coupling is completed, it will be ground and polished, and impurities will adhere to its surface, so the coupling needs to be cleaned. Most of the existing cleaning devices can only clean the couplings one by one, resulting in low cleaning efficiency. In response to the above technical problems, a Chinese patent with patent announcement number CN210907080U uses an intermittent gear to drive the coupling inside the placement groove to rotate during use, and then cleans the coupling with a brush roller and a brush disc. However, due to the different sizes of different couplings and the fixed position of the brush roller, it cannot be used for cleaning other models of couplings, and the inside of the coupling cannot be cleaned, which reduces the cleaning effect of the coupling.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] 1. Install the coupling to be cleaned in the cleaning cylinder.

Then the cleaning liquid passes through the filter box upward, and the impurities are collected in the filter box, so that the impurities cleaned on the coupling can be cleaned in time, improving the cleanliness of the cleaning liquid in the cleaning cylinder and avoiding the impurities from adhering to the coupling again. At the same time, the flow of the cleaning liquid can also rinse the surface of the coupling, further improving the cleaning effect of the coupling.

[0018] 3. When the turntable drives the cleaning cylinder to rotate, the first gear meshes with one set of incomplete gear rings and drives the first rotating shaft to rotate, thereby causing the cover plate to rotate and seal the end of the cleaning cylinder. By sealing the end of the cleaning cylinder through the cover plate, the cleaning liquid can enter the cleaning cylinder through the filter screen, and the impurities in the cleaning liquid are intercepted by the filter screen, thereby reducing the probability of impurities entering the cleaning cylinder, reducing the impurity content in the cleaning cylinder, and reducing the probability of impurities adhering to the coupling, thereby further improving the cleaning effect of the coupling.

DETAILED DESCRIPTION

[0032] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0033] The specific implementation of the present invention is described in detail below in conjunction with specific embodiments.

[0034] like Figure 1-Figure 12 As shown, an automatic maintenance and cleaning device for a coupling provided by the present invention comprises a housing 1, a turntable 2 is rotatably installed in the housing 1, a first rotating power member 3 driving the turntable 2 to rotate is fixedly installed on the housing 1, and a plurality of cleaning cylinders 4 distributed in a circumferential array around the axis of the turntable 2 are fixedly installed on the turntable 2;

[0035] A guide rod 5 distributed along the radial direction of the turntable 2 is fixedly installed in the cleaning cylinder 4, a slider 6 and a slide plate 10 are slidably installed on the guide rod 5, a first fixed rod 8 perpendicular to the turntable 2 is rotatably installed on the side of the slider 6, a telescopic member 7 for driving the slider 6 to move is fixedly installed in the cleaning cylinder 4, a first brush 11 is arranged on the surface of the slide plate 10 close to the first fixed rod 8, the first brush 11 is distributed on both sides of the slide plate 10, the first brush 11 is distributed along the length direction of the slide plate 10, multiple groups of limiting rollers 12 are rotatably installed on both sides of the slide plate 10, and a side of the cleaning cylinder 4 away from the axis of the turntable 2 is rotatably installed There are two groups of second fixed rods 9 symmetrically distributed on both sides of the guide rod 5. The surface of the slide plate 10 away from the first fixed rod 8 is fixedly installed with elastic members 16 distributed around the guide rod 5. The end of the elastic member 16 away from the slide plate 10 is fixedly connected to the cleaning cylinder 4. A U-shaped moving frame 13 is slidably installed on the side of the cleaning cylinder 4 away from the axis of the turntable 2. A moving plate 14 is fixedly installed on the end of the moving frame 13 located in the cleaning cylinder 4. A second brush 15 is fixedly installed on the surface of the moving plate 14 close to the first fixed rod 8. A power assembly 38 for driving one group of the second fixed rods 9 to rotate is provided on the shell 1.

[0036] In actual application of this embodiment, the first rotating power member 3 drives the turntable 2 to rotate intermittently. When the cleaning cylinder 4 is at the highest point on the turntable 2, Figure 5 When the coupling 39 is in the position shown, the coupling 39 to be cleaned is installed in the cleaning cylinder 4. During installation, the slide plate 10 is inserted into the center hole of the coupling 39 until the slide plate 10 passes through the coupling 39. At this time, the coupling 39 can be released. Under the action of gravity, the coupling 39 will move downward and contact the first brush 11. After the first brush 11 is bent and deformed, the coupling 39 will contact the limiting roller 12. At this time, the coupling 39 will push the slide plate 10 to move downward and compress the elastic member 16 through the limiting roller 12, and the limiting roller 12 will prevent the first brush 11 from being pressed under the action of pressure. The first fixing rod 8 is moved downwards by the telescopic member 7, and the first fixing rod 8 contacts the coupling 39, and then the coupling 39 is pushed downwards until the coupling 39 contacts the two sets of second fixing rods 9 below. The coupling 39 is pressed against the second fixing rod 9 by the first fixing rod 8, so that the coupling 39 is placed and fixed, so that different types of couplings 39 can be fixed, and the practicability of the device is improved. At this time, under the action of gravity, the second brush 15 is close to the lower side wall of the cleaning cylinder 4 and does not contact the outer surface.

[0037] After the coupling 39 is installed, the turntable 2 rotates the set angle, and the cleaned coupling 39 in the uppermost cleaning cylinder 4 can be taken out and the uncleaned coupling 39 can be installed in the uppermost cleaning cylinder 4. When the coupling 39 is taken out, the telescopic member 7 is reset to release the fixation of the coupling 39. At this time, the cleaning cylinder 4 in the middle enters the cleaning liquid for soaking, and the cleaning cylinder 4 at the bottom is connected to the power assembly 38. When the cleaning cylinder 4 moves from the uppermost to the lowermost, it rotates 180 degrees. At this time, the second brush 15 moves downward under the action of gravity and is connected to the coupling The outer surface of the shaft 39 is in contact with the first brush 11 and the second brush 15. The power assembly 38 drives one group of second fixed rods 9 to rotate, and then the coupling 39 can be driven to rotate. When the coupling 39 rotates, the first brush 11 and the second brush 15 clean the inner wall and the outer surface of the coupling 39 respectively, thereby achieving comprehensive cleaning of the coupling 39, reducing the residual impurities inside the coupling 39, and improving the cleaning effect of the coupling 39. After cleaning, the turntable 2 continues to rotate the set angle, and the above steps are repeated to achieve continuous cleaning of the coupling 39, thereby improving the cleaning efficiency of the coupling 39.

[0038] In an example of the present embodiment, the first rotating power component 3 is a first motor, and of course it can also be other components that can output rotational power, such as a hydraulic motor. The turntable 2 is driven by the first motor to rotate intermittently. The telescopic component 7 is an electric telescopic rod, and of course it can also be other components that can actively change the length, such as a hydraulic cylinder. The first fixed rod 8 is driven up and down by the electric telescopic rod, and the electric telescopic rod can be powered by an independent power supply.

[0039] like Figure 2 , Figure 4 , Fig. 9 As shown, an automatic maintenance and cleaning device for a coupling provided by the present invention, the power assembly 38 includes a second rotating power member 33 and a cover 23, the cover 23 is fixedly mounted on the turntable 2 and is provided in multiple groups, the cover 23 corresponds to the position of the cleaning cylinder 4, and the corresponding cover 23 is coaxially arranged with the cleaning cylinder 4, a second rotating shaft 24 is rotatably mounted on the cover 23, the second rotating shaft 24 passes through the cover 23 and a driving ring gear 25 located in the cover 23 is fixedly mounted on the second rotating shaft 24, the driving ring gear 25 is meshed with a second gear 26 fixedly mounted on the end of one group of second fixed rods 9, and the second rotating shaft 24 is connected to the second rotating power member 33.

[0040] Specifically, the second rotating power member 33 is fixedly mounted on the side wall of the housing 1 and its output shaft extends into the housing 1. The end of the output shaft of the second rotating power member 33 is fixedly mounted with an electromagnet 34. After the electromagnet 34 is energized, it adsorbs the iron plate 27 fixedly mounted on the end of the second rotating shaft 24. The cleaning cylinder 4 rotates to the lowest point on the turntable 2. Figure 6In the position shown, the second rotating shaft 24 is coaxial with the output shaft of the second rotating power member 33 , and the electromagnet 34 is in sliding contact with the iron plate 27 .

[0041] In actual application of this embodiment, when a group of cleaning cylinders 4 rotate to the lowest position on the turntable 2, Figure 6 When in the position shown, the turntable 2 stops rotating and the second rotating shaft 24 is coaxial with the output shaft of the second rotating power member 33, the electromagnet 34 is in contact with the iron plate 27 and there is no pressure between the two, and the electromagnet 34 is energized. After the electromagnet 34 is energized, it adsorbs the iron plate 27, and the second rotating power member 33 can drive the second rotating shaft 24 to rotate. The second rotating shaft 24 drives one group of the second fixed rods 9 to rotate through the meshing driving ring gear 25 and the second gear 26, thereby rotating the coupling 39 in the cleaning cylinder 4. After cleaning, the electromagnet 34 is powered off, and then the turntable 2 can continue to rotate.

[0042] In one embodiment of the present invention, the second rotating power component 33 is a second motor, and of course it can also be other components capable of outputting rotating power, such as a hydraulic motor. The second motor drives the coupling 39 to rotate, thereby achieving comprehensive cleaning of the coupling 39.

[0043] like Figure 5-Figure 12 As shown in the figure, an automatic maintenance and cleaning device for a coupling provided by the present invention is provided. A through slot 17 is provided on the turntable 2 and is located in the cleaning cylinder 4. The cleaning cylinder 4 rotates to the lowest point on the turntable 2. Figure 6 In the position shown, the through groove 17 is located directly below the cleaning tube 4 , the arc-shaped inner wall of the through groove 17 is flush with the inner wall of the cleaning tube 4 , and the through groove 17 is connected to the cover 23 .

[0044] Specifically, a filter box 28 slides inside the cover 23, the filter box 28 contacts the turntable 2 and the position of the filter box 28 corresponds to the position of the through slot 17, the side of the filter box 28 close to the turntable 2 is an open structure, the opening area of ​​the filter box 28 covers the through slot 17, the surface of the filter box 28 away from the turntable 2 is a closed structure and a magnet 29 is fixedly installed thereon, the magnet 29 is adsorbed on the cover 23, and the cover 23 is made of magnetic material.

[0045] Specifically, a baffle 30 is rotatably mounted at the open end of the filter box 28 . When the baffle 30 is in a vertical state, the opening of the filter box 28 is completely closed. A stopper 31 for limiting the rotation angle of the baffle 30 is fixedly mounted in the filter box 28 .

[0046] Specifically, a water pump 36 is fixedly installed on the outer side of the housing 1, and the water pump 36 is connected to a water pumping pipe 35 and a return pipe 37. The water pumping pipe 35 extends into the housing 1, and the water pumping pipe 35 is connected to a connecting pipe 32 fixedly installed on the cover 23. The cleaning cylinder 4 rotates to the lowest point on the turntable 2. Figure 6In the position shown, the connecting pipe 32 is aligned and connected with the water suction pipe 35 , and the end of the return pipe 37 away from the water pump 36 extends into the housing 1 .

[0047] Specifically, multiple groups of first rotating shafts 18 are rotatably installed on the turntable 2, and the first rotating shafts 18 correspond to the positions of the cleaning cylinder 4. First gears 21 and cover plates 19 are fixedly installed at both ends of the first rotating shaft 18, and a filter screen 20 is arranged in the middle of the cover plate 19. When the turntable 2 rotates, the first gear 21 engages with two groups of incomplete gear rings 22 fixedly installed on the inner wall of the shell 1. When the first rotating shaft 18 rotates, it drives the cover plate 19 to rotate. When the cover plate 19 rotates, its side surface slides in contact with the end surface of the cleaning cylinder 4.

[0048] In actual application of this embodiment, the cleaning cylinder 4 is located at the highest point on the turntable 2. Figure 5 When the cleaning cylinder 4 is in the position shown, the cover plate 19 does not close the cleaning cylinder 4. When the turntable 2 drives the cleaning cylinder 4 to rotate, the first gear 21 meshes with one group of incomplete gear rings 22 and drives the first rotating shaft 18 to rotate, thereby causing the cover plate 19 to rotate and close the end of the cleaning cylinder 4. When the closing is completed, the first gear 21 disengages from the incomplete gear ring 22. Subsequently, the position of the cover plate 19 is maintained by the damping or magnetic adsorption of the first rotating shaft 18. The end of the cleaning cylinder 4 is closed by the cover plate 19, and the cleaning liquid can enter the cleaning cylinder 4 through the filter screen 20. The impurities in the cleaning liquid are intercepted by the filter screen 20, thereby reducing the probability of impurities entering the cleaning cylinder 4, reducing the impurity content in the cleaning cylinder 4, and reducing the probability of impurities adhering to the coupling 39, thereby improving the cleaning effect of the coupling 39. After cleaning is completed, the turntable 2 continues to drive the cleaning cylinder 4 to rotate. At this time, the first gear 21 meshes with another group of incomplete gear rings 22. When the cleaning cylinder 4 is located at the highest point on the turntable 2 as shown in FIG. Figure 5 In the position shown, the two are separated from each other to release the cover plate 19 from sealing the cleaning cylinder 4, and the coupling 39 in the cleaning cylinder 4 can be replaced at this time;

[0049] The cleaning cylinder 4 is located at the lowest point on the turntable 2. Figure 6When cleaning in the position shown, the connecting pipe 32 is aligned with the water pump 35 and connected. The water pump 36 extracts the cleaning liquid in the cover 23 and the cleaning cylinder 4 through the connecting pipe 32 and the water pump 35. The cleaning liquid in the housing 1 enters the cleaning cylinder 4 through the filter 20, and then enters the cover 23 through the through groove 17, and is finally pumped out by the water pump 36. When the cleaning liquid flows in the cleaning cylinder 4, it drives the impurities cleaned on the coupling 39 to move. When the cleaning liquid flows, it pushes the baffle 30 to rotate so that the cleaning liquid can carry the impurities into the filter box 28. After that, the cleaning liquid passes through the filter box 28 upwards, and the impurities are collected in the filter box 28, so that the impurities cleaned on the coupling 39 can be cleaned in time, improving the cleanliness of the cleaning liquid in the cleaning cylinder 4, and preventing the impurities from adhering to the coupling 39 again. At the same time, the flow of the cleaning liquid can also rinse the surface of the coupling 39, further improving the cleaning effect of the coupling 39. After the cleaning is completed, the cleaning liquid in the cleaning cylinder 4 no longer flows, and the baffle 30 is reset to close the filter box 28 under the action of gravity to prevent the impurities from flowing out;

[0050] After cleaning is completed, when the cleaning cylinder 4 rotates, the filter box 28 will flip over, and the baffle 30 will be restricted by the block 31 to prevent the baffle 30 from opening too large and prevent impurities in the filter box 28 from flowing out. The filter box 28 can be removed and the impurities therein can be cleaned.
