AI Technical Summary

Technical Problem

Traditional bearing inner ring grinding methods are inefficient and difficult to mass-produce, especially when faced with different installation postures or complex curved surface structures, they cannot achieve efficient and precise integrated grinding.

Method used

It adopts a vertical high-efficiency bearing inner ring grinding device, combined with a guide shaft and slide table structure, to provide a high-precision vertical motion trajectory. With the help of a rotatable and adjustable grinding clamp and an electric push rod driven adjustment handle, the grinding angle can be precisely adjusted. The material rack adopts a three-layer stepped arrangement for orderly management and flexible movement of workpieces.

Benefits of technology

It improves the stability and precision of the grinding process, enhances equipment adaptability and loading/unloading efficiency, and meets the needs of mass production.

Abstract

This application discloses a vertical, high-efficiency bearing inner ring grinding device, including a base plate. A material holder and a grinding assembly are arranged on the upper surface of the base plate. The grinding assembly includes a vertical guide seat, an intermediate grinding component, and a lifting drive. The vertical guide seat is connected to the intermediate grinding component via a sliding connector. A horizontal support plate is provided at the upper end of the vertical guide seat. The lifting drive is located on the upper surface of the horizontal support plate. The telescopic end of the lifting drive is connected to the intermediate grinding component. The intermediate grinding component includes an outer support frame, a grinding clamping seat, and a grinding component. A transition hole is provided on the side plate of the outer support frame. This application adopts a structure that combines a guide shaft and a slide table to provide a high-precision vertical motion trajectory for the intermediate grinding component, effectively preventing deviation during the grinding process. The grinding component is positioned between rotatably adjustable grinding clamping seats. Combined with an adjustment handle mechanism driven by an electric push rod, precise adjustment of the grinding angle is achieved to adapt to the needs of workpieces with different postures.
