AI Technical Summary

Technical Problem

In the existing worm gear box assembly process, it is difficult to guarantee the concentricity of the worm gear shaft and the bearing mounting hole, resulting in inconsistent assembly accuracy. This is especially true in multi-variety, small-batch production, where it is difficult to achieve efficient and stable bearing assembly.

Method used

A worm gear box bearing assembly device is adopted, which uses left and right ejector pin assemblies to press the worm gear shaft from both ends, and combines a push mechanism to automatically press the bearing. It uses an X, Y, Z three-axis screw adjustment system and cylinder drive to achieve precise positioning and stable pressing, replacing the traditional manual pressing process.

Benefits of technology

It improves the concentricity of the worm gear shaft and bearing mounting holes, enhances assembly consistency and efficiency, reduces manual labor intensity, adapts to the installation requirements of worm gear boxes of different specifications, and ensures the stability of product quality and the versatility of equipment.

Abstract

The application discloses a worm gear box bearing assembling device and a method thereof and belongs to the field of worm gear box assembling. The technical scheme is as follows: a worm gear box bearing assembling device comprises a device main body, a right thimble assembly and a left thimble assembly are installed on the device main body, the right thimble assembly comprises a right thimble, the left thimble assembly comprises a left thimble, the right thimble and the left thimble are oppositely arranged, the right thimble assembly and / or the left thimble assembly further comprises a bearing pressing ring, the bearing pressing ring is sleeved on the outer periphery of the right thimble and / or the left thimble, the bearing pressing ring is connected with a pushing mechanism, and the pushing mechanism can drive the bearing pressing ring to move in the axial direction of the right thimble assembly and / or the left thimble assembly. The right and left thimbles are oppositely arranged, the worm shaft can be tightly pressed from both ends, the problem of the worm shaft sagging due to gravity can be effectively corrected, and the concentricity of the worm shaft and the bearing mounting hole is guaranteed; the pushing mechanism drives the bearing pressing ring to automatically press and assemble the bearing, replaces the traditional manual press assembly or heating sleeve assembly process, and improves the consistency and efficiency of bearing assembly.
