AI Technical Summary

Technical Problem

Existing bearing external groove precision grinding equipment suffers from low efficiency and low equipment utilization. In particular, in mass production, frequent start-stop and idle strokes lead to capacity bottlenecks, and the robotic arm loading and unloading system is complex and costly.

Method used

The multi-station turntable layout and built-in bearing fixing drive unit enable continuous cyclic operation of automatic feeding, clamping, fine grinding and unloading of bearing rings. By using the intermittent indexing rotation of the material turntable and the tensioning and positioning of the bearing fixing drive unit, combined with the servo motor driven fine grinding mechanism, the structure is simplified and the cost is reduced.

Benefits of technology

It significantly shortens auxiliary time, improves processing cycle time and equipment efficiency, reduces dependence on complex external loading and unloading systems, realizes continuous automated production line, and improves overall equipment efficiency.

Abstract

This invention discloses an automated precision grinding equipment for bearing external grooves, relating to the field of bearing manufacturing technology. It includes a base, a material-carrying turntable, guide posts, multiple bearing fixing drive units, and a precision grinding mechanism. The material-carrying turntable has multiple positioning grooves circumferentially and is driven to rotate intermittently by a drive device. The guide posts are fixed to the base, and their surfaces have two guide closed-loop grooves with specific contours. Each bearing fixing drive unit corresponds to one positioning groove and includes a liftable hollow column and hollow shaft, a radial tensioning key driven by an inclined pressure block, and first and second rollers that cooperate with the guide grooves. The precision grinding mechanism at the precision grinding station drives the clamped bearing to rotate via a bevel gear pair, while a radially feedable grinding head performs groove precision grinding. This invention achieves continuous automated operation of the entire bearing process from loading, clamping, processing to unloading, significantly improving production efficiency and equipment utilization, and has a compact structure and low cost.
