Bearing riveting machine

Abstract

The invention discloses a bearing riveting machine which comprises a stander, driving equipment, a lead screw mechanism connected with the driving device, an upward press slide plate connected with a lead screw nut of the lead screw mechanism, two downward press slide plates respectively sheathed on two stand column guide rods, two press machine lower faceplates arranged at the bottom of the stand column guide rods, and a plurality of pressure sensors arranged between the press machine lower faceplates and the downward press slide plates. The lead screw is driven by the driving device to rotate, so that the lead screw nut and the upward press slide plate connected with the lead screw nut are driven to move up and down, and the lead screw nut and the upward press slide plate are moved at ascrew pitch up and down when the lead screw is rotated at one circle. The lead screw is higher in stroke precision, so that the riveting stroke precision of the machine is correspondingly improved, the riveting stroke of the machine can be accurately controlled by controlling the convolution of the driving equipment, and the rotation motion is converted to be linear motion. The withdrawing force after a rocker arm bearing is riveted can reach 3500N, so that the problem that the rocker arm bearing is fallen off during using can be avoided, and the problem of sale quality can be completely eradicated.

Description

technical field [0001] The invention relates to the technical field of bearing riveting, in particular to a bearing riveting machine. Background technique [0002] In an automobile engine, the rocker arm that controls the opening and closing of the cylinder intake and exhaust valves is a lever structure. There is a rocker shaft hole in the middle of the rocker arm, and a fork-shaped bearing seat at the outer end of the rocker arm. There are bearing holes on the fork-shaped bearing seat. , the axis of the bearing hole is parallel to the axis of the rocker arm shaft hole, and the rocker arm bearing matched with the cam is arranged on the fork bearing seat, and the inner end of the rocker arm is the connection end with the valve. When working, the rocker arm shaft hole in the middle of the rocker arm is sleeved on the rocker arm shaft as the fulcrum of the lever, and the rocker arm bearing is attached to the cam. When the cam rotates, the rocker arm is pushed to swing periodica...

AI Technical Summary

Problems solved by technology

In the past, punching equipment was used for riveting. Due to the unstable control of the riveting stroke and the unstable riveting force of the punching equipment, not only the production efficiency is low, the pull-out force of the bearing after riveting is unstable, and the qualified rate of the product is not high.
