[0002] Modern development places higher and higher demands on the automation level of the manufacturing industry. In the field of main reducer assembly line technology, press-fitting the outer ring of the guide bearing on the reducer housing is one of the indispensable assembly processes. However, when press-fitting the guide bearing, due to the weak strength of the guide bearing seat of the reducer housing, the press-fitting may cause plastic deformation of the reducer housing guide bearing seat, which may seriously damage the reducer housing, thus affecting the overall quality of the product. Therefore, it is necessary to design a reaction force support for the reducer housing bearing seat to offset the force on the reducer housing bearing seat during the press-fitting process. However, the bottom of the reducer housing guide bearing seat is a cast rough surface with an error of ±1.5mm; this brings great trouble to the reaction force support of the guide bearing seat. Therefore, we propose a floating reaction force support mechanism and equipment for press-fitting of guide bearings. Summary of the invention

[0029] The slide assembly drives the support block to move to the reducer housing and the guide bearing mounting position. The robot first grabs the reducer housing onto the support block. Since the preset height of the workpiece positioning fixture 22 is relatively high, the reducer housing guide bearing seat will squeeze the workpiece positioning fixture 22 under the action of gravity when the reducer housing is mounted, compressing the spring 20. The support block 16, the guide flat key 18, and the boss bolt 21 move downward together. This step realizes the close contact between the reducer housing guide bearing seat and the workpiece positioning fixture 22 under the action of the spring 20. The robot then places the outer ring of the guide bearing on the workpiece positioning fixture 22. On the guide bearing positioning surface of the tooling 22; the slide starts to transport the reducer housing and the outer ring of the guide bearing to the pressing position; then the wedge block cylinder 2 starts to push the load-bearing wedge block 10 to dock with the support block 16. Since the self-locking angle of the wedge blocks is 7°, the cylinder inserts the load-bearing wedge block 10 into the support block 16 and the reducer housing guide bearing seat can achieve rigid support; when the pressure head presses the guide bearing on the equipment, the reducer housing guide bearing seat can be transmitted to the fuselage base in sequence through the workpiece positioning tooling 22, the support block 16, and the load-bearing wedge block 10, so as to avoid the reducer housing guide bearing seat being subjected to force.
