[0019] The following is a clear and complete description of the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings in the embodiments of the present invention. In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention can also be implemented in other ways different from those described herein, and those skilled in the art can make similar generalizations without violating the connotation of the present invention, so the present invention is not limited by the specific embodiments disclosed below.

[0020] like Figures 1 to 5As shown, a vertical press for motor assembly provided by an embodiment includes a base 1 and a gantry 2 arranged on the base 1, a pressing member 21 driven by a top oil cylinder is arranged under the crossbeam of the gantry 2, and the pressing member 21 is used to press the motor core into the motor housing. The above is the basic structure of the prior art, and the improvements of the present application are as follows:

[0021] A lifting member 4 is arranged inside the gantry 2, and the lifting member 4 comprises a coaxial upper annular plate 41 and a lower annular plate 42;

[0022] The upper surface of the lower annular plate 42 is provided with a plurality of slide grooves (not shown) in a radial array, a sliding rod 43 is provided in the slide groove, a vertical rod 431 is provided on the top surface of the sliding rod 43, and a plurality of arc-shaped slide grooves 44 are provided on the top surface of the lower annular plate 42;

[0023] A plurality of vertically penetrating strip holes 411 are arranged on the circumference of the upper annular plate 41. The number and position of the strip holes 411 correspond to the number and position of the slide grooves. The strip holes 411 are inclined relative to the corresponding slide grooves 44. The vertical rods 431 extend into the strip holes 411. A plurality of arc-shaped protrusions 413 are arranged on the bottom surface of the upper annular plate 41. The arc-shaped protrusions 413 are slidably arranged in the arc-shaped slide grooves 44. The cross-sections of the arc-shaped protrusions 413 and the arc-shaped slide grooves 44 are both inverted T-shaped structures, and the length of the arc-shaped protrusions 413 is less than the length of the arc-shaped slide grooves 44.

[0024] The lifting member 4 is driven to rise and fall by a lifting device, which is two downwardly arranged oil cylinders 3. The oil cylinders 3 are arranged in notches 221 opened on the side plates 22 of the gantry 2. The lifting member 4 also includes two cross bars 5 fixedly arranged on both sides of the lower ring member 42. The lower ring member 42 is fixedly connected to the cylinder rods (not marked) of the two oil cylinders 3 through the two cross bars 5.

[0025] A handle 412 is disposed on the upper annular plate 41 , a pin hole 45 is disposed on the outer edge of the upper annular member 41 , and a plurality of pin holes 45 are arranged in a circumferential array on the outer edge of the lower annular member 42 .

[0026] When in use, first lower the lifting member 4 to the upper surface of the base 1, rotate the upper annular plate 41 clockwise by the handle 412 to make the sliding rod 43 move toward the center of the lifting member 4, and fix the relative position of the two annular members by inserting the pin into the pin hole 45, and then move the motor movement onto the lifting member 4, support the motor movement by the extended sliding rod 43, control the oil cylinder 3 to lift the lifting member 4, and then move the motor casing to just below the lifting member 4, move the lifting member 4 down, so that the bottom of the sliding rod 43 is adjacent to the top of the motor casing, pull out the pin, rotate the upper annular plate 41 counterclockwise, so that the sliding rod 43 moves outward so that the motor movement can pass through and fall above the motor casing. Since the motor movement is located in the center of the two annular plates, the two annular plates can also play a role in positioning and guiding the movement. At this time, drive the lower pressing member 21 to press the motor movement into the motor casing, and then lift the lifting member 4 to remove the assembled motor from the base.

[0027] Furthermore, the top surface of one end of the sliding rod 43 close to the center of the lifting member 4 is a slope 432, the purpose of which is to make the motor movement gradually descend when the sliding rod 43 moves outward, thereby reducing the collision strength with the motor housing.

[0028] Furthermore, a groove 6 is provided on the base 1, and the groove 6 is located directly below the lifting member 4. The shape of the groove 6 corresponds to the shape of the lifting member 4. Before loading the motor movement, the lifting member 4 is first lowered into the groove 6 to facilitate the loading of the motor movement.

[0029] In order to ensure that the bottom of the motor housing is supported by a plane to increase stability after it is moved into place, a movable supporting plate 7 for covering the groove 6 and two movable supporting plates such as Figure 2 The groove-shaped track 71 is shown, and the supporting plate 7 moves along the track 71. After the motor movement is lifted, the supporting plate 7 is moved to the bottom of the lifting member 4.

[0030] Obviously, the described embodiments are only some embodiments of the utility model, not all embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
