Embodiment 1

[0061] A specific embodiment of the present invention discloses an automatic press-fitting system for double-fork bushing bearings, which includes: a slide rail mechanism 4, a sliding clamp 5, a press-fitting mechanism 6 and a turning mechanism 7; wherein the sliding clamp 5 is used for Fix the double-pronged bushing 1, and the sliding fixture 5 can slide on the linear guide rail 41 of the slide rail mechanism 4; the turning mechanism 7 can clamp the double-pronged bushing 1 and turn it over; the press-fitting mechanism 6 is set on the slide rail mechanism 4, and the press-fit mechanism 6 is used to press-fit the bearing on the bifurcated bushing 1.

[0062] In the double-prong bushing bearing automatic press-fitting system of the present invention, the double-prong bushing 1 is installed on the sliding fixture 5, and the sliding fixture 5 is driven to linearly displace by the slide rail mechanism 4, and then the double-prong bushing 1 is paired by the press-fitting mechanism 6...

Embodiment 2

[0108] A specific embodiment of the present invention discloses an assembly method of a double-pronged bushing bearing. The double-pronged bushing bearing automatic press-fitting system in Embodiment 1 is used to press-fit the two-pronged bushing 1 to the bearings at both ends. Include the following steps:

[0109] Step S1: Drive the sliding fixture 5 to slide to the first station along the linear guide rail 41; when the sliding fixture 5 is in the first station, place the first bearing 2 on the bearing positioning tool 51, and place the double-fork bushing 1 on the second station A shaft sleeve positioning tool 52;

[0110] Step S2: Drive the sliding fixture 5 to slide to the second station along the linear guide rail 41; when the sliding fixture 5 is located at the second station, the press-fitting mechanism 6 drives the magnetic indenter 65 to move down, and the magnetic indenter 65 absorbs the second station by magnetic force. a bearing 2;

[0111] Step S3: Drive the sli...

Abstract

The invention relates to a double-fork shaft sleeve bearing automatic press-fitting system and an assembling method, and belongs to the technical field of automatic assembling. The problems that a bearing is prone to being damaged and the mounting precision is poor during press-fitting of the double-fork shaft sleeve bearing in the prior art are solved. The double-fork shaft sleeve bearing automatic press-fitting system comprises a sliding rail mechanism used for driving a sliding block clamp to move, the sliding block clamp used for positioning the bearing and a double-fork shaft sleeve, a press-fitting mechanism used for press-fitting the bearing on the double-fork shaft sleeve, and an overturning mechanism used for overturning the double-fork shaft sleeve with one end provided with the bearing in a press-fitting mode. After the bearing is pressed at one end of the double-fork shaft sleeve, the double-fork shaft sleeve is overturned through the overturning mechanism, and then the bearing is pressed at the other end of the double-fork shaft sleeve through the press-fitting mechanism. Automatic press fitting of bearings on the two sides of the double-fork shaft sleeve is achieved.

Description

technical field [0001] The invention relates to the technical field of automatic assembly, in particular to an automatic press-fitting system and an assembling method for double-fork bushing bearings. Background technique [0002] The double-fork shaft sleeve is an important transmission part of the steering gear transmission mechanism. Its working principle is that after the two forks of the shaft sleeve are respectively matched with the support sleeves on the ball screw pair, the ball screw pair is driven by the motor to move along the axial direction. The double-fork bushing moves up and down, and then drives the angle change of the angular displacement sensor to realize the adjustment of the attitude angle of the steering gear device. Among them, the installation state of the bearings at both ends of the double-fork bushing directly affects the assembly accuracy and rotation flexibility of the double-fork bushing, which in turn affects the control accuracy of the entire ...
