[0034] Please refer to the drawings Figures 1-4This utility model provides an auxiliary assembly device for a bearing housing, comprising a mounting support 10, a limiting mechanism 20, and a clamping assembly mechanism 30. First, it should be noted that, unlike existing technologies that generally employ manual assembly relying on the visual judgment and fitter skills of assembly workers to adjust the assembly process of the bearing 410 and bushing 420, this method addresses the aforementioned deficiencies of the prior art by providing an auxiliary assembly device for a bearing housing. Specifically:

[0035] The bottom end of the mounting support 10 has a positioning part 111, which is used for positioning and installing the bushing 420 of the bearing housing 40; the first end of the limiting mechanism 20 is connected to the middle of the mounting support 10, and the second end of the limiting mechanism 20 has a limiting space 240, which is used for the bearing 410 of the bearing housing 40 to pass through, and the second end of the limiting mechanism 20 is openable and closable; the pressing assembly mechanism 30 is connected to the top of the mounting support 10, and the pressing assembly mechanism 30 has a pressing part 320 that is vertically movable, and the pressing part 320 is disposed above the bearing 410 of the bearing housing 40.

[0036] Specifically, the bearing housing auxiliary assembly device in this application includes a mounting support 10, a limiting mechanism 20, and a clamping assembly mechanism 30. The mounting support 10 is used for mounting the limiting mechanism 20 and the clamping assembly mechanism 30. The bottom end of the mounting support 10 also has a positioning part 111 for positioning the bushing 420 of the bearing housing 40, thereby improving stability during assembly. The limiting mechanism 20 provides auxiliary horizontal limiting for the bearing 410 of the bearing housing 40, preventing displacement caused when pressing down on the bearing 410 and improving assembly accuracy. The second end of the limiting mechanism 20 has a limiting space 240 for the bearing 410 to pass through. The second end of the limiting mechanism 20 is openable and closable for easy installation. When open, it facilitates the installation of the bearing 410, and when closed, it forms a limiting space 240 for limiting. The pressing assembly mechanism 30 is used to press the bearing 410 downward. By manipulating the pressing part 320, which is vertically movable, to move downward, it squeezes the bearing 410 when it comes into contact with the bearing 410, thereby slowly pressing the bearing 410 into the bushing 420 to complete the assembly. Therefore, the pressing part 320 needs to be set above the bearing 410 of the bearing housing 40.

[0037] As a preferred embodiment of the present application, the positioning part 111 is a positioning groove formed by recessing the bottom of the mounting support 10, and a threaded hole is formed in the positioning groove.

A threaded hole is formed in the positioning groove, which corresponds to the hole on the shaft sleeve 420 of the bearing seat 40, so that the positioning connection is achieved through the screw connection, which is quick and convenient to disassemble and assemble.
