By means of the structure, after the press-fitting shaft sleeve and the positioning guide piece are connected in a sleeved mode, the relative position positioning of the press-fitting shaft sleeve and the positioning guide piece is achieved, the press-fitting shaft sleeve can only move linearly relative to the positioning guide piece, and therefore after the positioning guide piece is positioned relative to the motor, when the press-fitting shaft sleeve moves relative to the positioning guide piece, pressure perpendicular to an oil seal is applied to the oil seal reliably, and the oil seal cannot be inclined.
The diameter of the outer surface of the press-fitting part 4 of the press-fitting shaft sleeve 1 is smaller than that of the inner surface of the mounting boss 11. By means of the structure, when the press-fitting component applies pressure on the oil seal, the outer surface of the press-fitting component cannot be in contact with the mounting protrusion 11, interference is avoided, the press-fitting component is limited, positioning and guiding are achieved through the press-fitting positioning piece, and reliability is high.
The press-fitting boss 8 of the motor end face oil seal positioning press-fitting jig comprises a press-fitting boss horizontal plane 16 and a press-fitting boss vertical plane 17, the press-fitting boss vertical plane 17 is of an annular structure, and the diameter of the press-fitting boss vertical plane 17 is smaller than that of an oil seal inner surface 18 of the oil seal 13. Above-mentioned structure, when pressure equipment part and oil blanket contact, there is the clearance between pressure equipment boss vertical 17 of pressure equipment part and the oil blanket internal surface, like this, ensures to exert external force in pressure equipment boss horizontal plane 16 all the time, and can not act on pressure equipment boss vertical 17, can not cause the oil blanket to receive the foreign object contact and warp, improves oil blanket installation precision.
The positioning boss 9 of the motor end face oil seal positioning press-fitting jig comprises a positioning boss horizontal plane 19 and a positioning boss vertical plane 20, and the positioning boss vertical plane 20 is of an annular structure. By the structure, the positioning boss is reliably and accurately clamped and positioned with the oil seal mounting position.
When the motor end face oil seal positioning and press-fitting jig positions and press-fits the oil seal 13 to the oil seal mounting position 12, a gap part structure is arranged between the lower surface 22 of the oil seal 13 and the bottom surface 23 of the groove part of the oil seal mounting position 12. The existence of clearance avoids damaging the oil blanket during pressure equipment.
When the press-fitting positioning boss 7 of the press-fitting part 4 of the motor end face oil seal positioning press-fitting jig abuts against the upper surface of the mounting boss 11, the oil seal 13 is set to be of a structure capable of being mounted in place in the oil seal mounting position 12. Above-mentioned structure through the setting of pressure equipment location boss 7 of pressure equipment part 4, carries on spacingly to the stroke of pushing down of pressure equipment part, and this stroke is the stroke that needs the oil blanket pressure equipment promptly, like this, does not need artifical the control pressure equipment stroke when carrying out the oil blanket pressure equipment, as long as the location boss supports and leans on the protruding 11 upper surface of installation, shows that the pressure equipment targets in place promptly, and the reliability is high.
The motor end face oil seal positioning and press-fitting jig further comprises a positioning support, an adsorption magnet is arranged at the bottom of the positioning support, a telescopic cylinder is further installed on the positioning support, and a telescopic rod of the telescopic cylinder is of a vertically-arranged structure. Above-mentioned structure through telescopic cylinder's setting, realizes the automation of the upper and lower control of pressure equipment part 4 of pressure equipment axle sleeve 1, improves the accuracy of dynamics control.
