Press fitting device for front and rear bushings of automobile chassis control arm

Abstract

The invention relates to a press fitting device for front and rear bushings of an automobile chassis control arm, wherein the device comprises a cabinet, a front bushing positive pressing mechanism, a front bushing positioning back pressing mechanism and a rear bushing press-fitting mechanism; a working face is arranged on the upper side of the cabinet; the front bushing positive pressing mechanism is provided with a front bushing pressing head rod; the front bushing positioning back pressing mechanism is provided with a front steel bushing positioning piece, and the front steel bushing positioning piece and the front bushing pressing head rod are coaxially arranged; and the rear bushing press-fitting mechanism is fixed to the working face through a second mounting base, a rear steel bushing positioning piece is fixedly arranged on the surface of the working face, and the rear steel bushing positioning piece and the rear bushing pressing head are coaxially arranged. Press fitting of a rear bushing, press fitting of a front bushing and back pressing of the front bushing are achieved at a time after one-time clamping and positioning, repeated clamping and positioning are not needed, the position precision of the front bushing and the rear bushing after press fitting is improved, the assembly production process and the assembly time are shortened, the press fitting cost of the front bushing and the rear bushing of a control arm is reduced, and the press-fitting quality and the press-fitting efficiency of the front bushing and the rear bushing of the control arm are ensured.

Description

Technical field [0001] The present invention relates to the field of automotive chassis system assembly technology, and more particularly to a car chassis control arm front and rear liner press press. Background technique [0002] The automobile control arm is used as the guide and power components of the automobile suspension system, and the various power to the wheel is passed to the vehicle body while ensuring that the wheel moves in a certain track. The car control arm is flexiblely linked together by the ball hinge or bushing, and the bushing of the existing car control arm includes a front bushing and a rear bushing, the front bushing is mounted in the front steel sleeve, the rear liner Set in the rear steel sleeve. [0003] Currently, for similar attachment figure 1 Before and after the control arm, the known assembly process is that the front bushing and the rear bushing are respectively compressed, increase the cost of assembly production, low economic benefits; and posi...

Problems solved by technology

[0004] The present invention aims to solve the problems existing in the press-fitting process of the front and rear bushes of the similar control arm, such as multiple processes, long assembly lines, low economic benefits, low position accuracy of the bushes after press-fitting, and failure to detect and judge the control arm with abnormal pressure during the press-fitting process, etc. The problem is to provide a press-fitting device for the front and rear bushings of the control arm of the automobile chassis. After one clamping and positioning, the rear bushing, the front bushing and the front bushing can be press-fitted in one time. Since it does not need repeated clamping and positioning, The position accuracy of the front and rear bushings after pressing is improved, the assembly production process and assembly time are shortened, and the cost of pressing the front and rear bushings of the control arm is reduced, and the pressure of each pressing process can be detected and displayed in real time. The control arm with abnormal pressure will give an alarm reminder to prevent the control arm with abnormal pressure from entering the next process during the press-fitting process, so as to ensure the press-fit quality of the front and rear bushings of the control arm
