Description

Technical Field

[0001] The utility model relates to the technical field of engine maintenance, in particular to a stator pressing device. Background Art

[0002] The stator is the stationary part of the motor or generator. The stator consists of three parts: the stator core, the stator winding and the base. During the maintenance of the engine, the stator may have faults such as loose stator core, broken winding, short circuit, grounding, etc. If a problem is detected with the stator, the stator needs to be removed from the engine casing for repair or replacement.

[0003] The removal of the stator often requires the use of external force to pull it out of the casing. Generally, maintenance workers use their hands to gently knock the stator with a hammer or a wooden stick from the side or bottom to loosen it, and then use their hands or tools to pull the stator out. Manual removal of the stator is not only inefficient and low in precision, but also poses a safety hazard. For this reason, we have proposed a stator press-out device. Utility Model Content

Two extension rods are fixedly inserted on the upper surface of the mounting plate corresponding to the two sides of the cylinder. The lower ends of the two extension rods extend to the lower end of the mounting plate and are fixedly connected to a guide plate. A circular groove is opened in the middle of the guide plate, and a telescopic part is movably inserted above the upper surface of the guide plate corresponding to the circular groove.

[0010] Compared with the prior art, the utility model provides a stator extrusion device, which has the following beneficial effects:

[0011] The stator pressing device uses a cylinder in conjunction with a guide device to press out the stator. Compared with manual operation, the stator can be removed in a shorter time, improving maintenance efficiency. It can also ensure the stability and accuracy of the stator removal and reduce the damage rate.

[0025] Working principle: When the device is used to remove the stator of an engine or generator for repair or replacement, first remove all the screws on the casing cover, place the casing with the screws removed in the top fixing frame 4 of the equipment support frame 1, rotate the threaded rods 10 on both sides to push the clamping plate 11, so that the clamping plate 11 clamps the casing shell, which is convenient for subsequent pressing and disassembly of the stator, and the casing will not move; open the extrusion shaft 9, control the air intake at both ends of the cylinder 6 through the extrusion shaft 9, so that the piston rod pushes downward, and the piston rod pushes the extrusion shaft 9 downward, The over-pressing shaft 9 is pressed onto the motor shaft at the lower end, and the stator is separated from the motor housing under the action of pressure. After separation, the switch of the cylinder switch 7 is toggled back to its original position; after the piston rod is reset, the pressure on the top of the extrusion shaft 9 disappears, and the spring 15 is deformed and reset, pushing the telescopic part 14 upward to reset, and the telescopic part 14 drives the extrusion shaft 9 at the lower end to reset, and the next stator extrusion can be carried out; if the pressing force of the piston rod is insufficient or too large, the pressing force of the cylinder 6 can be adjusted by adjusting the air pressure regulator 8 to control the amount of air intake and exhaust of the cylinder switch 7.
