The electric cylinder 3 is a linear motor of the prior art, and the execution end of the electric cylinder 3 can drive the relative height of the vertical adjustment mechanism, which has been used to adjust the relative height of the casing 6 to meet the requirements of the casing 6 of different diameters being concentric with the core shaft 7.

[0021] A base 9 is installed on the welding plate 4, and the fixed block 5 is fixedly installed on the base 9. A limit screw 10 is arranged on the base 9. The lower end of the translation slider 8 is slidably connected to the base 9, and one end of the translation slider 8 can abut against the outer periphery of the limit screw 10. A threaded hole is provided on the translation slider 8, and a screw 11 is connected to the thread in the threaded hole, and one end of the screw 11 is rotatably sleeved on the fixed block 5, and a hand wheel 12 is installed on the other end of the screw 11.

[0022] Working process of a track lifting device for a casing for a submersible motor stator stacking:

[0023] Manually rotate the aluminum alloy handwheel 12, and the screw 11 will rotate accordingly. The screw 11 and the translation slider 8 are threadedly connected, so the rotation of the screw 11 drives the translation slider 8 to move left and right. The translation slider 8 and the lifting slider 6 are connected by a dovetail-type wedge-shaped boss 7, so the left and right movement of the translation slider 8 drives the lifting slider 6 to move up and down, and the roller 1 mechanism also moves up and down with the lifting slider 6.

[0024] During the process of stacking the stator of the submersible motor stator stacking equipment, the stator core and the casing are placed on several track lifting devices respectively, the stator core is inserted into the casing and stacked, and the stator core and the casing need to have particularly good horizontality and coaxiality. The leveling process can be completed by manually turning the hand wheel 12. During the stacking process, according to the different sizes of the stator core and the casing, the piston rod of the electric cylinder 3 drives the roller 1 mechanism to the preset position. Since the diameter of the casing is larger than the stator core, when the casing passes through the stator core, the track lifting devices under the stator core descend one by one, and then rise one by one after passing through to support the casing.
