Example 1
The present embodiment will further explain the present utility model by taking a deformation assembly process of a 6006-2RZ type bearing as an example;
when the first set of bearings are assembled, a power supply QS is turned on to enable the working circuit to be powered on, and a control cabinet power supply SB is pressed down to enable the control circuit to be powered on; assuming that the compressing mechanism 4 is positioned at the middle position of the stroke, the two-end stroke limit switches are not bumped, so that the KM2 coil is electrified to start the motor, the compressing mechanism 4 moves towards the right fixed stop block 3, and the bearing outer ring can be extruded; when the deformation degree of the outer ring just can assemble all balls, the motor is turned off, the position of the pressing mechanism 4 is recorded, and the right travel limit switch SQ2 is adjusted and moved to the position of the pressing mechanism 4.
