[0016] The following is a non-limiting detailed description of the technical solution of the present invention in conjunction with preferred embodiments and their accompanying drawings. Obviously, the described embodiments are only a portion of the embodiments of the present invention, and not all of them. All other embodiments derived by persons of ordinary skill in the art based on the embodiments of the present invention without inventive effort are also within the scope of protection of the present invention.

By arranging the cabinet 1, the Formazan wheel 2, the press 3, the bearing pressure head 4, the mounting plate 5, the vertical starting clamp 6, the guide column 7, the workpiece 8, the return spring 9, the linear bearing 10, the bearing positioning plate 11 and the limit retaining ring 12, it is convenient to position the bearing and the workpiece, thereby improving the installation accuracy, and the overall operation is simple, which improves the convenience of operation, solves the time-consuming and labor-intensive problems caused by complicated operation, and meets people's work needs.

[0018] Furthermore, the outer wall of the bearing positioning plate 11 is provided with an arc-shaped installation groove on one side, and the other side of the installation groove is in a slotted state, which facilitates the positioning of the bearing.

[0019] Furthermore, the bearing pressing head 4 and the mounting groove on the outer wall of the bearing positioning plate 11 are aligned with each other, and the mounting groove and the workpiece 8 are aligned with each other, which facilitates the press-fitting work.

[0020] Furthermore, the linear bearing 10 forms a telescopic structure with the guide column 7 through the reset spring 9, and the linear bearing 10 and the guide column 7 are slidably connected, which facilitates the reset and sliding of the linear bearing 10.

[0021] Furthermore, the size of the limit ring 12 is larger than that of the linear bearing 10, and the limit ring 12 and the linear bearing 10 abut against each other, which facilitates the limiting of the linear bearing 10 when it is reset and slid.

[0022] During use, first install the workpiece into the interior of the vertical starting clamp 6 for positioning, and install the bearing into the installation groove of the bearing positioning plate 11 for positioning, then start the press 3, so that the press 3 drives the bearing pressure head 4 to press down, so that the bearing pressure head 4 drives the bearing positioning plate 11 to slide downward, and the bearing positioning plate 11 drives the bearing to slide downward, so that the bearing is installed into the workpiece 8 for pressing. During this process, the bearing positioning plate 11 drives the linear bearing 10 to slide, so that the linear bearing 10 drives the return spring 9 to compress and deform. When the bearing pressure head 4 rises subsequently, the elasticity of the return spring 9 will cause the linear bearing 10 to drive the bearing positioning plate 11 to reset and slide up, thereby ensuring the effective installation space of the bearing and the workpiece 8, thereby improving the convenience of the overall operation.
