[0028] The lifting mechanism 2 includes a servo motor 21 fixed to the top of the installation vertical plate 1. The bottom output end of the servo motor 21 is drivingly connected to a vertically arranged transmission lead screw 22. The bottom of the transmission lead screw 22 is rotatably fixed to the front surface of the installation vertical plate 1. A lead screw slider 23 is drivingly connected to the surface of the transmission lead screw 22. Two vertical slide rails 24 are arranged parallel to each other along the vertical direction on both sides of the transmission lead screw 22;

[0029] The back of the cylinder mounting frame 31 is fixedly connected to the lead screw slider 23 in the lifting mechanism 2. The servo motor 21 drives the transmission lead screw 22 to drive the lead screw slider 23 and the cylinder mounting frame 31 to move up and down;

[0030] Two cylinder mounting frame sliders 310 are symmetrically arranged on the back of the cylinder mounting frame 31. The cylinder mounting frame sliders 310 are slidably sleeved on the surface of the vertical slide rails 24 of the lifting mechanism 2, so that the cylinder mounting frame 31 can slide up and down along the vertical slide rails 24 in a limited manner;

[0031] The top of the limiting block 45 is fixedly connected to a guide post mounting plate 42 through four upper top pressing-in guide posts 43. The four upper top pressing-in guide posts 43 are arranged along the vertical direction. The four upper top pressing-in guide posts 43 are sleeved through a guide sleeve 44.

The press-in bracket sliders 410 are slidably sleeved on the surface of the vertical slide rail 24 of the lifting mechanism 2, so that the press-in bracket 33 can slide up and down along the vertical slide rail 24;

[0034] The working principle of the utility model is as follows:

[0035] In the actual use of the utility model, the housing and stator assembly and the rotor and shaft assembly are assembled to grasp the top pressing mechanism. In the grasping stage: the transmission screw 22 in the lifting mechanism 2 is driven by the servo motor 21 to descend to the specified position and decelerate to drive the entire pressing mechanism 3 and the upper top pressing mechanism 4 to descend, and the centering pressing plate 39 is pressed down into the housing and stator assembly 5 and stops. The centering pressing plate 39 plays the role of determining the center of the circle, and determining the center of the circle is convenient for the upper top 46 to be pressed in later. After the center of the circle is determined, the clamping claw cylinder 35 drives the clamping claw 36 to clamp and fix the housing and stator assembly 5. Then it enters the pressing stage: the transmission screw 22 in the lifting mechanism 2 stops when the servo motor 21 descends to the specified position. At this time, the positioned upper top 46 is pushed by the upper top pressing cylinder 41 to support the center hole of the rotor shaft 7, so that the rotor shaft 7 is aligned with the axial position of the casing and stator assembly 5. Because the casing and stator assembly 5 have been centered when grabbing, the center hole of the rotor shaft 7 is just aligned with the center of the casing and stator assembly 5. Then, under the push of the pressing cylinder 32, the upper top 46 is kept stationary, the centering pressure plate 39 is pressed down, and the casing and stator assembly 5 is pressed into the rotor and shaft assembly 6 to complete the assembly.

[0036] The advantage of this mechanism is the centering, including the centering of the pressing plate when grabbing the housing and stator assembly, and the centering of the upper tip against the center hole of the rotor shaft before pressing down. Only when both are centered, the pressing will be smooth, which is also the key to the success of this mechanism. Because the shaft is relatively long, it is easy to deflect in practice. If the upper tip does not support the center hole of the shaft and is not centered, the housing and stator assembly cannot be pressed in smoothly. The utility model realizes precise centering and pressing, saving time and effort, and has broad application prospects.
