The automobile control arm, including the bush and the bulb connected with the automobile control arm, should have sufficient rigidity, strength and service life. During operation, the control arm bush is connected with the auxiliary frame through the bolt, plays the effect that the buffering road surface strikes the automobile body, promotes driving comfort.
The control arm bushing is a transition part for connecting a chassis control arm and a vehicle body in an automobile suspension system, and fig. 1 is a structural diagram of a common control arm bushing. The control arm bushing is of a three-layer structure, the outermost side and the innermost side are made of steel materials with connecting and fixing functions, the middle layer is made of rubber materials with a buffering function, and the three parts are pre-assembled together and cannot be divided.
The control arm bushing and the control arm are in interference fit, and the control arm bushing is pressed into the control arm through press-fitting equipment. In the press fitting process, the press fitting needs to be ensured to be in place, meanwhile, in order to ensure the normal use of the automobile control arm, strict requirements are generally also required on the press-in force, and for the control arm bushing shown in fig. 1, the press-in force is generally required to be 10-40 kN.
The common press-fitting method generally adopts a press machine to directly perform press-fitting. However, because the shape of the automobile control arm is irregular, proper positioning reference is not provided, and the control arm is not easy to be righted, quality defects such as control arm slippage, bushing pressure distortion and the like are very easy to occur during press mounting, and even potential safety hazards exist; and the press fitting efficiency is extremely low, and the requirement of mass production cannot be met at all.

Before using, lay the car control arm on the control arm fixing base, notice, the inboard equal and control arm fixing base side laminating of two connecting rods of control arm.
The operation will be described with reference to the left side. The hydraulic pressure station is started at first, after the hydraulic pressure station works stably, the left bush is sleeved on the left pressure head, then the left oil cylinder is started, the left oil cylinder drives the piston rod to extend out, the left pressure head is driven, the left bush is pressed into the bush mounting hole in the left side of the control arm, and in the pressing-in process of the left bush, the specific numerical value of the pressing-in force is displayed on the electric cabinet at all times.
The right side and the left side have the same working principle.
In order to improve the high production efficiency, the left oil cylinder and the right oil cylinder can be started simultaneously, the left bushing and the right bushing can complete press fitting work simultaneously, and the electric cabinet can display the specific numerical value of the actual press-in force of the left bushing and the right bushing at any time.
The utility model discloses can satisfy the needs that car control arm bush impressed, the during operation, car control arm gesture is stable, the pressure equipment is reliable, has the characteristics that the operation of being convenient for, the force of impressing show in real time often simultaneously.
