It is used to move the chain link and move relative to the polishing mechanism 6 for polishing. The polishing mechanism 6 includes: Two movable blocks 61 are slidably connected in a rectangular through hole opened in the inner wall of the fixed base 2; Two rotating rods are rotatably connected to the movable block 61 and located on the outside of the fixed base 2; Two polishing cylinders 63 are fixedly sleeved on the outer wall of the rotating rod and used for polishing the track links; Two polishing motors 62 are fixedly connected to the moving block 61 and located inside the fixed base 2. The output end of the polishing motor 62 is connected to the rotating rod to drive the rotating rod to rotate the polishing cylinder 63.
[0017] Polishing mechanism 6 also includes: The slide rod 65 is fixedly connected to the inner wall of the fixed base 2; The bidirectional threaded rod 66 has two ends rotatably connected to the inner wall of the fixed base 2, and one end movably passes through the fixed base 2 and extends outward; Each movable block 61 has two fixed adjusting blocks 64, with the upper adjusting block 64 slidably connected to the outer wall of the slide rod 65 and the lower adjusting block 64 threadedly connected to the outer wall of the bidirectional threaded rod 66.
[0018] The movable seat 3 is internally equipped with a clamping mechanism 4, which includes: Two movable blocks 42 are movably connected to the inner wall of the movable seat 3, and push rods 43 are fixedly connected to the top and bottom of the inner wall of the movable seat 3 respectively, and the output end of the push rods 43 is connected to the movable blocks 42 for pushing the movable blocks 42 to move. Two U-shaped clamping grooves 41 are respectively set on one side of the outer wall of the movable seat 3 and connected to the movable block 42 through a connecting rod.
[0019] The movable seat 3 has two rectangular holes, and the connecting rod slides within the rectangular holes.
[0020] The bottom of the movable seat 3 is provided with a moving mechanism 5 for moving the movable seat 3; Mobile mechanism 5 includes: Three supports 51 are all fixedly connected to the bottom of the workbench 1; The reciprocating screw 53 is rotatably connected to the two supports 51 on the left side, and a motor 52 is fixedly connected to the right side of the middle support 51. The output end of the motor 52 is connected to the reciprocating screw 53 to drive the reciprocating screw 53 to rotate. Multiple sliders 54 are fixedly connected to the bottom of the movable seat 3, and the middle slider 54 is sleeved on the outer wall of the reciprocating lead screw 53.
[0021] The workbench 1 has multiple sliding holes, and the slider 54 is attached to and slides along the inner wall of the sliding hole.
[0022] Working principle: When polishing the track link, the upper and lower sides of the track link to be polished are placed in the U-shaped clamping groove 41. By activating the two push rods 43 respectively, the movable blocks 42 are moved closer to each other. The connecting rod moves the U-shaped clamping grooves 41 closer to each other, thus clamping the track link. After clamping, the polishing motor 62 is activated, which drives the rotating rod to rotate and drives the two polishing cylinders 63 to rotate. Then, the starting motor 52 moves, which drives the reciprocating screw 53 to rotate, which in turn drives the slider 54 to move, thus moving the movable seat 3. By moving the movable seat 3, the track link is brought closer to the polishing cylinder 63. According to the distance between the two mounting holes on the track link, the bidirectional threaded rod 66 is rotated. The bidirectional threaded rod 66 pushes the adjusting block 64 to move on the sliding rod 65, which in turn drives the two movable blocks 61 to move relative to each other to adapt to the distance between their two mounting holes. By moving the movable seat 3, the track link is moved left and right and comes into contact with the polishing cylinder 63, thus polishing the inner wall of the track link 3. Furthermore, by continuously moving the movable seat 3 left and right, the position of the track link relative to the polishing cylinder 63 can be changed, thereby achieving a better polishing effect; At the same time, the two moving blocks 61 can be further adjusted to move away from each other, and after the track link moves to contact the polishing cylinder 63, the outer walls on both sides of the track link can be polished, further improving the polishing effect.
[0023] This utility model provides a polishing device for track links. There are many methods and approaches to implement this technical solution. The above description is only a preferred embodiment of this utility model.

All components not explicitly stated in this embodiment can be implemented using existing technology.
