A milling machine for automatic gap finding in sliding bearings

By designing an oil groove milling machine for automatic groove finding of sliding bearings, the automatic docking and positioning of bearings is achieved by using a rotating loading and unloading module and a groove matching unit. This solves the problems of long manual tool setting time and high labor intensity in the existing technology, improves the milling accuracy and consistency, reduces the defect rate, and improves the quality of bearings.

AI Technical Summary

Technical Problem

In existing technologies, the automated milling process for bearings suffers from long manual tool setting time, high labor intensity, poor consistency in groove depth and width, and is prone to defects such as burrs and tool marks, which affect product quality.

Method used

A milling groove machine for automatic gap finding of sliding bearings was designed, including a rotating loading and unloading module, a gap matching unit, a loading and transporting unit, and a milling unit. The gap matching unit positions the bearing's mating seam, and the gap matching transport mechanism and gap finding mechanism are used to realize the automatic mating and positioning of the bearing, reducing manual intervention.

Benefits of technology

This technology enables automated milling of bearing grooves, reducing the workload and labor intensity of workers, improving the precision and consistency of grooves, reducing the defect rate, and enhancing product quality.

Abstract

A milling machine for automatically locating the joint of sliding bearings includes a rotating loading and unloading module, a joint alignment unit, a loading and transporting unit, and a milling unit. The joint alignment unit includes a joint transport mechanism, a joint finding mechanism, and joint clamping jaws. The joint finding mechanism includes a joint finding worktable, a first positioning fixture, a movable cylinder, and a second positioning fixture. The first positioning fixture includes a first positioning fixture body, a first positioning groove, a positioning through hole, a first sliding rod, a positioning pin, and a first buffer spring. Each second positioning fixture includes a second sliding rod, a second positioning fixture body, a second positioning groove, and a second buffer spring. After the first and second positioning fixtures stabilize the bearing, the joint transport mechanism drives the joint clamping jaws to rotate, causing the bearing on the joint clamping jaws to rotate synchronously, so that the positioning pin engages the open joint of the bearing, thus achieving the positioning of the bearing joint.
