The middle part of the outer surface of the rotating plate 207 is in contact with the inner wall of the through groove 209, and the upper and lower ends of the push plate 203 are fixedly connected to sliders 210, and the upper and lower ends of the shell 201 are provided with sliding grooves 211 used to cooperate with the slider 210. The top of the shell 201 and the two sides of the top of the table 1 are fixedly connected with the displacement device 3.

[0020] When the rotating plate 207 rotates under the push of the push plate 203, the second positioning wheels 208 at both ends of the rotating plate 207 approach the first positioning wheel 205, which can clamp the outer ring of the automobile bearing placed therebetween, and can effectively clamp and fix the automobile bearing.

[0021] The displacement device 3 includes two brackets 31, the bottom ends of the two brackets 31 are fixedly connected to the two sides of the top of the table 1 respectively, and the ends of the opposite surfaces of the two brackets 31 are jointly rotatably connected to the screw rod 32, one end of one of the brackets 31 is fixedly connected to the motor 33, the output end of the motor 33 passes through one of the brackets 31 and is fixedly connected to one end of the screw rod 32, the outer surface of the screw rod 32 is threadedly sleeved with a screw block 34, the upper part of the opposite end of the two brackets 31 is jointly fixedly connected to the guide rail 35, the lower part of the outer surface of the guide rail 35 is slidably connected to the guide block 36, the top of the screw block 34 is fixedly connected to the bottom end of the guide block 36, the bottom end of the screw block 34 is fixedly connected to four hydraulic rods 37 distributed in a rectangular array, and the bottom ends of the four hydraulic rods 37 are all fixedly connected to the top of the shell 201.

[0022] When the wire block 34 moves on the screw rod 32, the guide block 36 slides synchronously on the guide rail 35. The hydraulic rod 37 can drive the clamping device 2 to move the clamped bearing up and down, and the clamped automobile bearing outer ring can be moved to the required position for forging operation.

[0023] Working principle: When it is necessary to clamp the outer ring of the automobile bearing, the cylinder 202 starts working and its output end drives the push plate 203 to move in the housing 201. The slider 210 slides in the slide groove 211, so that the push plate 203 can only move stably along the straight line direction, ensuring the accuracy of subsequent actions. The push plate 203 is triangular. As the push plate 203 moves, it squeezes the second positioning wheel 208. Under the thrust of the push plate 203, the rotating plate 207 rotates around the rotating shaft 206, driving the rotating plate 207 to move. The second positioning wheel 208 at one end moves, and the through slot 209 limits and guides the rotation of the rotating plate 207, ensuring that the rotating plate 207 rotates stably within a preset plane. The rotating plate 207 moves synchronously with the push plate 203. When the rotating plate 207 rotates under the push of the push plate 203, the second positioning wheels 208 at both ends of the rotating plate 207 move closer to the first positioning wheel 205, which can clamp the outer ring of the automobile bearing placed between them, thereby achieving the purpose of effectively clamping and fixing the automobile bearing.

[0024] When the horizontal position of the clamping device 2 needs to be adjusted, the motor 33 is started, and the output end of the motor 33 drives the screw rod 32 to rotate. When the screw rod 32 rotates, the wire block 34 with a threaded sleeve on its outer surface moves axially along the screw rod 32 under the action of the thread. In order to ensure the stability of the movement of the wire block 34, when the wire block 34 moves on the screw rod 32, the guide block 36 slides synchronously on the guide rail 35 to prevent the wire block 34 from rotating with the rotation of the screw rod 32, ensuring that the wire block 34 can only move in a straight line direction. The hydraulic rod 37 can drive the bearing clamped and fixed by the clamping device 2 to move up and down, thereby achieving the purpose of moving the clamped automobile bearing outer ring to the desired position for forging operation.

[0025] Obviously, those skilled in the art may make various modifications and variations to the present invention without departing from the spirit and scope of the present invention. Thus, if such modifications and variations fall within the scope of the claims of the present invention and their equivalents, the present invention is intended to include such modifications and variations.
