[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] Example: Figure 1-3 As shown, this utility model provides a pressing machine for assembling automotive wheel hub bearings. It is mainly supported by a base frame 1. A pressing mechanism 2 and a fixing mechanism 3 are fixedly provided on the upper end of the base frame 1. The pressing mechanism 2 includes a reset frame 201. A pressing frame 20 is fixedly connected to one side of the reset frame 201. A cylinder 21 is fixedly provided on one side of the pressing frame 20. The output end of the cylinder 21 is fixedly connected to one side of the moving inclined plate 22. One side of the moving inclined plate 22 cooperates with the sliding inclined plate 25. The sliding inclined plate 25 slides in the sliding groove 24 through the sliding wheel 202. A pressing mold 23 is fixedly provided at the lower end of the sliding inclined plate 25. A reset plate 27 is fixedly connected to the sliding inclined plate 25. A reset rod 29 passes through the reset groove 28 and cooperates with the reset plate 27. A reset spring 26 is sleeved on the reset rod 29.

[0018] The cooperation between the sliding groove 24 and the sliding wheel 202 reduces friction and ensures the smooth movement of the sliding inclined plate 25. The sliding contact between the reset groove 28 and the reset rod 29 ensures the stability of the reset plate 27 during the reset process. The inclined surface design of the moving inclined plate 22 allows the thrust of the cylinder 21 to be converted into the vertical pressing force of the sliding inclined plate 25.

[0019] The fixing mechanism 3 is supported by the fixing frame 30. A rotating plate 33 is fixedly provided on the inner surface of the fixing frame 30. A rotating rod 37 is provided inside the rotating plate 33. The output end of the motor 32 is fixedly connected to the lower end of the rotating rod 37. Two rotating locking rods 38 are fixedly provided on the upper end of the rotating rod 37. The rotating locking rods 38 cooperate with the rotating locking grooves 35 inside the clamping plate 301. An arc-shaped plate 36 is fixedly provided on the upper end of the clamping plate 301.

[0020] The mounting bracket 31 provides stable support for the motor 32. The sliding contact between the rotating groove 39 and the rotating rod 37 ensures the stability of the rotating rod 37 during rotation. The sliding contact between the clamping groove 34 and the rotating plate 33 enables the clamping plate 301 to stably follow the rotating rod 37 in rotation.

[0021] Working principle: When the bearing needs to be pressed, the cylinder 21 is activated through the pressing mechanism 2, and its output end pushes the moving inclined plate 22 to move. Since one side of the moving inclined plate 22 is inclined, it will push the sliding inclined plate 25 to move downward in the sliding groove 24 through the sliding wheel 202, thereby driving the pressing mold 23 to press the automobile wheel hub bearing. After pressing is completed, the cylinder 21 returns, and the return spring 26 pushes the sliding inclined plate 25 to reset through the return rod 29 and the return groove 28.

[0022] When the bearing needs to be fixed, the motor 32 operates, and its output end drives the rotating rod 37 to rotate. The rotating rod 37 cooperates with the rotating slot 35 inside the clamping plate 301 through the rotating clamp 38, so that the clamping plate 301 can move towards the center in coordination with the rotating rod 37. Since the upper end of the clamping plate 301 is fixed with an arc plate 36, when the rotating rod 37 rotates, the arc plate 36 will clamp and fix the car wheel hub, thereby ensuring the stability during the pressing process.

[0023] Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
