The first guide rail 120 and the second guide rail 130 are perpendicular to each other, so that the bearing 20 can be placed on conveyor belt 122 and conveyor belt 2 132. One end of the bearing 20 is in contact with conveyor belt 122, and the other end of the bearing 20 is in contact with conveyor belt 2 132. A conveyor belt 122 for conveying the bearing 20 is installed in the middle of the first guide rail 120, and both ends of the first guide rail 120 are hinged with a rotating wheel 121 for facilitating the rotation of the conveyor belt 122. The rotating wheel 121 and the rotating wheel 2 131 have the same size and structure. The conveyor belt 122 is sleeved on the middle of the rotating wheel 121, and a connecting shaft 123 for limiting the rotating wheel 121 is fixedly installed in the middle of the rotating wheel 121. One end of the connecting shaft 123 is provided with a conical tooth 124, and the conical tooth 124 and the conical tooth 2 134 are meshed, so that when the conical tooth 2 134 rotates, it drives the conical tooth 124 to rotate, and the conical tooth 124 drives the connecting shaft 123 to rotate, so that the rotating wheel 121 and the rotating wheel 2 131 rotate synchronously, and drive the conveyor belt 122 to cooperate with the conveyor belt 2 132 to convey the bearing 20.

[0033] A conveyor belt 132 is installed in the middle of the second guide rail 130 for cooperating with the conveyor belt 122 to convey the bearing 20, and both ends of the cleaning box 100 are hinged with a rotating wheel 131 for facilitating the rotation of the conveyor belt 132. The conveyor belt 132 is sleeved on the middle of the rotating wheel 131. A connecting shaft 133 for limiting the rotating wheel 131 is fixedly installed in the middle of the rotating wheel 131. A conical tooth 134 for meshing with the conical tooth 124 is fixedly installed in the middle of the connecting shaft 133.

When it is necessary to clean the inner surface of the bearing 20, the bearing 20 is placed on the upper ends of the conveyor belts 122 and 132, and the bearing 20 is conveyed to the interior of the cleaning box 100 through the conveyor belts 122 and 132. The two clamping modules 200 in the inner cavity of the cleaning box 100 clamp the bearing 20, and then the sandblasting machine 300 can be started to clean the bearing 20.

[0034] The inner cavity of the cleaning box 100 is installed with a clamping module 200 for clamping the bearing 20, and one end of the clamping module 200 is installed with an electric push rod 10 for controlling the movement of the clamping module 200. One end of the electric push rod 10 is fixedly installed on the inner wall of the cleaning box 100, and the other end of the electric push rod 10 is fixedly installed on one end of the clamping module 200, so that after the electric push rod 10 is started, it drives the clamping module 200 to approach the bearing 20 and clamp the bearing 20.

[0035] The clamping module 200 includes an L-shaped clamping block 210 for preliminary clamping of the bearing 20. The L-shaped clamping block 210 is arranged as a horizontal plate and a vertical plate. When the electric push rod 10 drives the clamping module 200 to approach the bearing 20, the horizontal plate of the L-shaped clamping block 210 is at the upper end of the bearing 20, and the vertical plate of the L-shaped clamping block 210 contacts the side of the electric push rod 10.

[0036] A connecting toothed rod 211 for limiting the position of the L-shaped clamping block 210 is fixedly installed at one end of the L-shaped clamping block 210, a limiting slider 212 for limiting the position of the connecting toothed rod 211 is fixedly installed at one end of the connecting toothed rod 211, a spring 240 for controlling the limiting slider 212 to reset is pressed against one end of the limiting slider 212, and a toothed block 213 for controlling the rotation of the rotating rod 250 is fixedly installed at the middle lower end of the connecting toothed rod 211. When the electric push rod 10 drives the clamping module 200 to approach the bearing 20, the horizontal plate of the L-shaped clamping block 210 first moves to the upper end of the bearing 20, and then the vertical plate of the L-shaped clamping block 210 contacts the side of the bearing 20, synchronously driving the connecting toothed rod 211 to move in the direction of the spring 240, so that the limiting slider 212 squeezes the spring 240, and the toothed block 213 rotates synchronously with the gear 252, driving the rotating rod 250 to rotate.

[0037] The first clamping plate 220 and the second clamping plate 230 for further clamping the bearing shell 20 are installed at both ends of the clamping module 200.

A connecting rod 231 for cooperating with the rotating rod 250 to control the movement of the second clamping plate 230 is fixedly installed at one end of the second clamping plate 230. One end of the connecting rod 231 is sleeved on the other end of the rotating rod 250, so that when the rotating rod 250 rotates, the first clamping plate 220 and the second clamping plate 230 are driven to move closer to or farther from each other.

[0038] The clamping module 200 is internally installed with a rotating rod 250 for cooperating with the L-shaped clamp block 210 to control the first clamp plate 220 and the second clamp plate 230 to approach each other. Both ends of the rotating rod 250 are provided with spiral grooves 251 for controlling the movement of the first clamp plate 220 and the second clamp plate 230, and the groove cavities of the spiral grooves 251 at both ends of the rotating rod 250 are in opposite directions, so that when the first clamp plate 220 and the second clamp plate 230 move, the movement directions of the first clamp plate 220 and the second clamp plate 230 are opposite. A gear 252 is fixedly installed in the middle of the rotating rod 250 for cooperating with the tooth block 213 to control the rotation of the rotating rod 250, so that when the L-shaped clamp block 210 and the bearing 20 come into contact with each other to drive the connecting tooth rod 211 to move, the connecting tooth rod 211 drives the tooth block 213 to move in the direction of the spring 240, and then drives the gear 252 to rotate, so that the gear 252 drives the rotating rod 250 to rotate, and under the guidance of the spiral groove 251, drives the first clamp plate 220 and the second clamp plate 230 to approach each other and clamp the side of the bearing 20.

[0039] A sandblaster 300 for cleaning the bearing 20 is installed at the upper end of the inner cavity of the cleaning box 100. A second connecting pipe 310 is fixedly installed at the upper end of the sandblaster 300. The second connecting pipe 310 is used to transport quartz sand and clean the inner wall of the bearing 20 through compressed air. A second limit block is fixedly installed at the upper end of the sandblaster 300. A second motor 330 for controlling the rotation of the second limit block is installed in the middle of the second limit block. The second limit block is fixedly installed on the rotating shaft of the second motor 330, so that when the second motor 330 is started, the second limit block is driven to rotate, thereby driving the angle of the sandblaster 300 to change, thereby cleaning the arc-shaped inner wall of the sandblaster 300, avoiding a single cleaning angle and causing insufficient cleaning.

[0040] A stop block 340 for limiting the position of the motor 2 330 is fixedly mounted on the connecting shaft of the motor 2 330, the motor 2 330 is fixedly mounted on the stop block 340, and a hole cavity for the rotation shaft of the stop block 340 is opened in the middle of the stop block 340, and a mounting block 341 for limiting the position of the stop block 340 is fixedly mounted on the upper end of the stop block 340, and the upper end of the mounting block 341 is fixedly mounted on the top of the inner cavity of the cleaning box 100 to stabilize the sandblasting machine 300. The utility model allows the bearing bush to be cleaned without manual operation by the operator, and is not easy to cause damage to the operator.

[0041] Based on the above content and the accompanying drawings, those skilled in the art can understand and implement the utility model. In addition, any non-creative modifications made to the utility model by those skilled in the art without making creative work still fall within the scope of protection of the utility model.
