[0017] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.
[0018] Example: Figure 1-3 As shown, the utility model provides an automobile wheel hub bearing assembly tool, including a base frame 1. The base frame 1 is the cornerstone of the entire device and is firmly placed at the bottom to provide solid support for other structures. Then, at the upper end of the base frame 1, the fixing mechanism 3 is firmly fixed. It is responsible for stably clamping the automobile wheel hub bearing during the assembly process, and the assembly mechanism 2 is cleverly arranged on one side of the fixing mechanism 3. The two are placed side by side to form a closely cooperative working area. Inside the assembly mechanism 2, the assembly frame 20 serves as the main frame, and a cylinder 21 is installed on one side of it. The output end of the cylinder 21 is connected to the sliding frame 22. The sliding frame 22 and the sliding plate 28 are slidably connected by a sliding wheel 24. The lower end of the sliding plate 28 is fixed with an extrusion plate 23 for extruding the bearing during assembly. In addition, a reset rod 27 and a reset spring 25 are also provided in the assembly frame 20. They cooperate with the sliding plate 28 to ensure that the extrusion plate 23 can be quickly reset after assembly is completed.
[0019] By designing one side of the sliding frame 22 as an inclined surface and slidingly fitting with the sliding wheel 24 on the sliding plate 28, the sliding plate 28 can slide smoothly under the drive of the cylinder 21. The reset groove 26 opened at the lower end of the sliding plate 28 and the sliding cooperation with the reset rod 27 provide a stable guide for the sliding plate 28. The design that the diameter of the upper half of the reset rod 27 is larger than the lower half can effectively limit the sliding plate 28 during the reset process.
[0020] The cam 35 is connected to the fixed frame 30 and the cam 36 is connected to the fixed frame 30 so that the cam 36 can rotate around the fixed point. The motor 32 is cleverly arranged at the lower end of the fixed frame 30 and is firmly connected to the fixed frame 30 through the support frame 31 to provide power for the rotation of the cam 36. The upper end of the cam 36 is fixed with two rotating rods 35, which can rotate synchronously under the drive of the rotating plate 36. The movable plate 33 slides with the fixed plate 37 through the movable groove 39 thereon and is sleeved on the rotating rod 35. It slides along the fixed plate 37 as the rotating rod 35 rotates. Finally, the positioning arc plate 34 is fixedly arranged at the upper end of the movable plate 33 for accurately positioning and clamping the automobile wheel hub bearing.
[0021] The support frame 31 added at the lower end of the motor 32 is firmly connected to the lower end of the fixed frame 30, providing solid support for the motor 32. The moving groove 39 opened on one side of the movable plate 33 slides with the fixed plate 37 to achieve smooth sliding of the movable plate 33 on the fixed plate 37. The rotating groove 38 opened on the inner wall of the movable plate 33 slides with the rotating rod 35 to provide a stable rotation track for the rotating rod 35.
[0022] Working Principle: The assembly mechanism 2 utilizes the driving force of the cylinder 21 to push the sliding frame 22 along its guide path. One side of the sliding frame 22 is designed as an inclined surface, which fits tightly with the sliding wheel 24 on the sliding plate 28, so that the sliding plate 28 can smoothly rise or fall along the inclined surface under the push of the cylinder 21. The movement of the sliding plate 28 further drives the lifting and lowering of the extrusion plate 23 fixed at its lower end, thereby realizing the assembly operation of the automobile wheel hub bearing. During the assembly process, the combined action of the reset rod 27 and the reset spring 25 ensures that the extrusion plate 23 can be quickly and accurately reset to its initial position after assembly is completed, so as to carry out the next assembly operation.
[0023] By designing one side of the sliding frame 22 as an inclined surface, and slidingly fitting with the sliding wheel 24 on the sliding plate 28, the sliding plate 28 can slide smoothly under the drive of the cylinder 21. The reset groove 26 provided at the lower end of the sliding plate 28 and the sliding cooperation of the reset rod 27 provide a stable guide for the sliding plate 28. The design of the upper half of the reset rod 27 having a larger diameter than the lower half can effectively limit the sliding plate 28 during the reset process.
[0024] The fixing mechanism 3 is driven by the motor 32 to rotate the rotating plate 36 around a fixed point on the inner surface of the fixed plate 37. As the rotating plate 36 rotates, the rotating rod 35 fixed thereon also rotates synchronously, thereby driving the movable plate 33 mounted on the rotating rod 35 to move along the sliding path of the fixed plate 37. This movement process enables the positioning arc plate 34 fixed to the upper end of the movable plate 33 to gradually approach and clamp the automobile wheel hub bearing placed in the fixed area. By adjusting the rotation angle and speed of the motor 32, it is possible to achieve precise positioning and stable clamping of bearings of different sizes, thereby meeting the assembly requirements of bearings of various specifications.
[0025] The support frame 31 added at the lower end of the motor 32 is firmly connected to the lower end of the fixed frame 30, providing solid support for the motor 32. The moving groove 39 opened on one side of the movable plate 33 slides with the fixed plate 37 to achieve smooth sliding of the movable plate 33 on the fixed plate 37. The rotating groove 38 opened on the inner wall of the movable plate 33 slides with the rotating rod 35 to provide a stable rotation track for the rotating rod 35.
[0026] 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.
