Description

Technical Field

[0001] This invention relates to the field of chain processing technology, and more particularly to an automatic cyclic polishing device for chain processing. Background Technology

[0002] Chain processing involves mechanical processes such as cutting, bending, and welding. After these processes, the chain surface is relatively rough. Moreover, during storage in warehouses or processing sites, the chain surface may rust. The rough surface and rust have an adverse effect on subsequent processing. Before further processing, the chain needs to be polished.

[0003] Chains are generally metal links or rings, primarily used for mechanical transmission and traction. A chain consists of multiple links assembled together, with curved ends and a straight middle section. Existing chain polishing devices can only polish the surface of the chain. When two links are nested together, the connection point is blocked, preventing polishing of either link and hindering omnidirectional polishing. Therefore, we propose an automatic circulating polishing device for chain processing to solve these problems. Summary of the Invention

[0004] The present invention proposes an automatic circulating polishing device for chain processing, which solves the problems in the background art.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

Two electric telescopic rods are fixedly installed inside the cavity. The output shaft of the electric telescopic rod is fixed with a sliding plate that is slidably installed inside the cavity. The end of the adjusting rod away from the support block slides through the through hole and extends into the cavity and is fixedly connected to the sliding plate.

[0014] As a preferred embodiment of the present invention, the position adjustment device includes two connecting rods fixedly installed inside the circular tube. One end of the connecting rod is fixed with a horizontal plate, and a guide rod is fixed between the two horizontal plates. A linear push rod is fixedly installed on one of the horizontal plates, and a movable plate is slidably installed on the guide rod. The push rod of the linear push rod is fixed to the movable plate. A linear push rod is fixedly installed on the movable plate. The push rod of the linear push rod is fixed with a moving plate slidably installed on the top of the movable plate. The output shaft of the moving plate is fixed with a vertically arranged linear push rod, and the push rod of the linear push rod is fixed with a mounting block.

[0015] As a preferred embodiment of the present invention, the driving device includes a housing rotatably mounted on a mounting block, a cylindrical rod rotatably mounted on one side of the housing, one end of the cylindrical rod being fixedly connected to a polishing brush, a motor being fixedly mounted inside the housing, and the output shaft of the motor being fixedly connected to the cylindrical rod. The angle adjustment device includes a low-speed motor fixedly mounted on the mounting block, and the output shaft of the low-speed motor being drively connected to the housing.

[0016] As a preferred embodiment of the present invention, the displacement device includes a U-shaped plate fixedly installed on the inner walls of both sides of a circular tube, a second reduction motor fixedly installed on the U-shaped plate, two vertical rods fixedly installed inside the U-shaped plate, a lifting plate slidably installed between the two vertical rods, a threaded column rotatably installed inside the U-shaped plate fixedly installed on the output shaft of the second reduction motor, the threaded column being threadedly connected to the lifting plate, a horizontally arranged cylinder fixedly installed on the lifting plate, a connecting plate fixedly installed on the piston rod of the cylinder, a sliding rod fixedly installed on one side of the connecting plate, one end of the sliding rod slidingly penetrating the lifting plate, and a polishing roller rotatably installed between the two sliding rods.

[0017] As a preferred embodiment of the present invention, the power device includes a rectangular cavity disposed on one of the slide bars, a drive motor is fixedly installed inside the rectangular cavity, and the output shaft of the drive motor is connected to the polishing roller via transmission.

[0018] As a preferred embodiment of the present invention, the chain traction device includes two assembly plates fixedly installed on the top of the base plate, a drive roller is rotatably installed between the two assembly plates, and a servo motor is provided on the assembly plate to drive the drive roller to rotate.

[0019] The beneficial effects of this invention are:

[0020] The chain is tractioned by two chain traction devices and passes through two circular tubes. The chain is positioned between two drive rollers. Activating servo motor three causes the drive rollers to rotate, driving the chain to move. Activating servo motor one, driven by a belt pulley, rotates circular tube one, causing the inner side of the chain link to be aligned with the extension line of the rotating shaft, facilitating the insertion of the rotating shaft into the chain link. Activating push rod motor causes the housing to move, allowing one end of the rotating shaft to be inserted into the chain link. Activating electric telescopic rod causes the sliding plate to move, moving the two adjusting rods away from each other, resulting in two support blocks moving away from each other. The two support blocks abut against the inner walls on both sides of the chain link, fixing the chain link. Then, activating reduction motor drives the rotating shaft to rotate 90 degrees, causing the chain link to rotate from a horizontal position to a vertical position. This allows the chain links at both ends of the fixed chain link to slide to the straight section of the chain link, exposing the curved sections at both ends of the fixed chain link.

[0021] The start motor drives the cylindrical rod to rotate, causing the polishing brush to rotate. The second linear push rod moves the moving plate horizontally, adjusting the horizontal position of the polishing brush. The first linear push rod moves the movable plate, adjusting the longitudinal position of the polishing brush. The third linear push rod raises and lowers the mounting block, adjusting the height of the polishing brush so that it moves to the arc-shaped structure at both ends of the chain link, polishing the inner and outer sides of the arc-shaped part of the chain link. By starting the low-speed motor to rotate the box and adjust the tilt angle of the box, the curved surface of the arc-shaped part of the chain link is polished, thus achieving all-round polishing of the arc-shaped structure of the chain link.

[0022] The drive motor is started to rotate the polishing roller, and the reduction motor is started to rotate the threaded column, which allows the height of the lifting plate to be adjusted. The length of the polishing roller is greater than the straight part of the chain link. The cylinder is started to move the connecting plate, which in turn moves the slide rod, causing the polishing roller to contact the straight part of the chain link for polishing. The outer side of the straight part of the chain link is polished. The servo motor is started to rotate the round tube under the drive of the pulley. The cylinder moves the connecting plate, which in turn moves the slide rod, causing the polishing roller to move to the inner side of the chain link. The reduction motor rotates the threaded column, which moves the lifting plate, thus polishing the inner side of the straight part of the chain link. This achieves all-round polishing of the straight part of the chain link.

[0023] This invention fixes the chain links, allowing them to rotate and expose the arc-shaped parts of the chain links, i.e., the connecting parts. Then, the arc-shaped and straight parts of the chain links are polished in all directions, achieving uniform polishing of the chain links from all angles and resulting in a good polishing effect.

[0039] Adjusting rods 17 are slidably mounted on both sides of one end of the rotating shaft 12. A support block 18 is fixed to one end of each adjusting rod 17. A cavity 14 is provided on the rotating shaft 12. Through holes are provided on both sides of the rotating shaft 12 and inside the cavity 14. Two electric telescopic rods 15 are fixedly installed inside the cavity. A sliding plate 16, slidably mounted within the cavity 14, is fixed to the output shaft of each electric telescopic rod 15. The end of the adjusting rod 17 away from the support block 18 slides through the through hole into the cavity 14 and is fixedly connected to the sliding plate 16. Activating the electric telescopic rod 15 causes the sliding plate 16 to move, moving the two adjusting rods 17 away from each other. This causes the two support blocks 18 to move away from each other, and the two support blocks 18 abut against the inner walls of both sides of the chain link, thus fixing the chain link.

[0040] A polishing brush 31 is installed inside the circular tube 4. The circular tube 4 also includes a position adjustment device for adjusting the spatial position of the polishing brush 31 and an angle adjustment device for adjusting the angle of the polishing brush 31.

The angle adjustment device also includes a low-speed motor 27 fixedly mounted on the mounting block 26, with its output shaft connected to the housing 28. By starting the low-speed motor 27 to rotate the housing 28, the tilt angle of the housing 28 is adjusted, allowing for the polishing of the curved portion of the chain link.

[0042] A straight-line polishing device is set on the top of the base plate 1 for polishing the straight parts of the chain. The straight-line polishing device includes a mounting plate 3 fixedly installed on the base plate 1, a round tube 5 rotatably installed on the mounting plate 3, and a servo motor 43 fixedly installed on the mounting plate 3.

When the servo motor 43 is started, the round tube 5 is driven to rotate under the transmission of the pulley.

[0043] Two polishing rollers 40 are installed inside the second circular tube 5. A displacement device for adjusting the spatial position of the polishing rollers 40 is installed inside the second circular tube 5. The displacement device includes a U-shaped plate 32 fixedly installed on the inner walls of both sides of the second circular tube 5. A second reduction motor 33 is fixedly installed on the U-shaped plate 32. Two vertical rods 34 are fixedly installed inside the U-shaped plate 32. A lifting plate 36 is slidably installed between the two vertical rods 34.

The length of the polishing roller 40 is greater than the transmission of the straight part of the chain link. The starting cylinder 37 drives the connecting plate 38 to move, so that the slide bar 39 moves, and drives the polishing roller 40 to contact the straight part of the chain link.

[0044] The displacement device is equipped with a power unit that drives the polishing roller 40 to rotate. The power unit includes a rectangular cavity set on one of the slide bars 39, and a drive motor 41 is fixedly installed in the rectangular cavity. The output shaft of the drive motor 41 is connected to the polishing roller 40 for transmission. Starting the drive motor 41 drives the polishing roller 40 to rotate.

[0045] A chain traction device is located on the top of the base plate 1. There are two chain traction devices, one for arc polishing and one for straight polishing, situated between them. Each chain traction device includes two assembly plates 6 fixedly mounted on the top of the base plate 1. A drive roller 8 is rotatably mounted between the two assembly plates 6. A servo motor 7, which drives the drive roller 8, is mounted on each assembly plate 6. The chain passes through the two chain traction devices, through a first circular tube 4 and a second circular tube 5, and is positioned between the two drive rollers 8. Activating the servo motor 7 causes the drive roller 8 to rotate, thus driving the chain to move.

[0046] Working principle: The chain is driven by two chain traction devices and passes through round tube 4 and round tube 5. The chain is located between two drive rollers 8. When servo motor 3 is started, the drive roller 8 rotates, driving the chain to move. When servo motor 42 is started, it drives round tube 4 to rotate under the belt pulley drive, so that the inner side of the chain link is located in the extension direction of the rotating shaft 12, so that the rotating shaft 12 can be inserted into the chain link. When push rod motor 10 is started, the housing 11 moves, so that one end of the rotating shaft 12 is inserted into the chain link. When electric telescopic rod 15 is started, the slide plate 16 moves, so that the two adjusting rods 17 move away from each other, so that the two support blocks 18 move away from each other. The two support blocks 18 abut against the inner walls of the two sides of the chain link to fix the chain link. Then, the first reduction motor 13 is started to drive the rotating shaft 12 to rotate 90 degrees, so that the chain link rotates from the horizontal position to the vertical position, so that the chain links at both ends of the fixed chain link slide to the straight part of the chain link, and the arc-shaped parts at both ends of the fixed chain link are exposed.

[0047] The starting motor 29 drives the cylindrical rod 30 to rotate, causing the polishing brush 31 to rotate. The starting linear push rod 23 drives the moving plate 24 to move horizontally, adjusting the horizontal position of the polishing brush 31. The starting linear push rod 21 drives the moving plate 44 to move, adjusting the longitudinal position of the polishing brush 31. The starting linear push rod 25 drives the mounting block 26 to lift and adjust, adjusting the height position of the polishing brush 31, so that the polishing brush 31 moves to the arc-shaped structure at both ends of the chain link, polishing the inner and outer sides of the arc-shaped part of the chain link. The starting low-speed motor 27 drives the box 28 to rotate, adjusting the tilt angle of the box 28, polishing the curved surface of the arc-shaped part of the chain link, thereby achieving all-round polishing of the arc-shaped structure of the chain link.

[0048] The drive motor 41 is started to rotate the polishing roller 40, and the second reduction motor 33 is started to rotate the threaded column 35, so that the lifting plate 36 is adjusted in height to adjust the height of the polishing roller 40. The length of the polishing roller 40 is greater than the transmission of the straight part of the chain link. The starting cylinder 37 drives the connecting plate 38 to move, which in turn moves the slide rod 39, causing the polishing roller 40 to contact the straight part of the chain link and polish the outer side of the straight part of the chain link. The second servo motor 43 is started to drive the round tube 5 to rotate under the transmission of the pulley. The cylinder 37 drives the connecting plate 38 to move, which in turn moves the slide rod 39, causing the polishing roller 40 to move to the inner side of the chain link. The second reduction motor 33 drives the threaded column 35 to rotate, which in turn moves the lifting plate 36, thus polishing the inner side of the straight part of the chain link, thereby achieving all-round polishing of the straight part of the chain link.

[0049] This invention fixes the chain links, allowing them to rotate and expose the arc-shaped parts of the chain links, i.e., the connecting parts. Then, the arc-shaped and straight parts of the chain links are polished in all directions, achieving uniform polishing of the chain links from all angles and resulting in a good polishing effect.
