AI Technical Summary

Technical Problem

In the prior art, the extension end of the connecting base plate of the bearing housing extends beyond the bearing assembly end, causing the side where the length and thickness of the bearing assembly end are located to tilt, making it impossible to perform milling operations normally.

Method used

Design a bearing housing positioning mechanism, including a positioning base with an L-shaped cross-section, a centering seat, a tie rod, a limiting block, a pressure seat, and a top seat. Through the cooperation of these components, ensure that the bearing assembly end of the bearing housing is horizontal on the side where the length and thickness are located, to meet the requirements of milling.

Benefits of technology

This achieved stable positioning of the bearing housing, simplified machining operations, reduced machining costs, and ensured the smooth progress of milling.

Abstract

A bearing seat positioning mechanism comprises a positioning base with an L-shaped cross section, a centering seat, a pull rod, a limiting block, a pressing seat and a top seat, the centering seat comprises a positioning disc assembled in a bearing hole of a bearing seat, the pressing seat comprises a pressing rod and two connecting rods, and the top seat comprises a seat body and a supporting bolt in threaded fit with the top of the seat body. The horizontal plane of the positioning base is fixedly installed on a milling machine table, one end of the pull rod is fixed to the vertical plane of the positioning base, and the other end of the pull rod extends in the horizontal direction, penetrates through the circle center of the positioning disc and the limiting block and is in threaded fit with the locking nut and a base body of the top base to be supported on the milling machine table. And the pressing rod is tightly pressed on the side face of the top of the bearing seat, so that the bearing seat is positioned. The device is simple in structure and low in machining cost, the bearing seat can be rapidly, efficiently and stably positioned, it is guaranteed that the side face where the length and the thickness of the bearing assembly end of the bearing seat are located is horizontal, and the milling requirement is met.
