After the rotor and the stator are placed and fixed at the bottom, when the position of the mounting bolts needs to be adjusted, the positioning needs to be released, and the motor rotor and stator need to be reversed before the positioning and mounting bolts are performed. This results in complicated assembly procedures of the rotor and stator and low processing efficiency. In addition, after the rotor and stator are assembled, the stator needs to be released before the assembled motor can be removed, resulting in low motor assembly efficiency and inconvenient operation.

[0015] Compared with the prior art, the beneficial effects of the utility model are:

DETAILED DESCRIPTION

[0023] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. The described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.

[0024] See also Figure 1-4 The utility model provides a technical solution: a motor assembly integrated machine, including a machine base 1, an electric turntable 2, a stroke cylinder 3, and a fixed block 51. A mounting platform 11 is integrally formed at the bottom of the machine base 1, and the electric turntable 2 is movably mounted at the top center of the mounting platform 11. Mounting columns 21 are fixedly mounted at equal intervals on the top of the electric turntable 2. A clamping plate 22 is rotatably mounted inside the mounting column 21. A positioning seat 23 and a return spring 26 are respectively arranged at the top center of the electric turntable 2.

[0025] A positioning block 27 is integrally formed at the bottom of the positioning seat 23, a stroke cylinder 3 is fixedly installed on the top of the machine base 1, a fixed tube 4 is fixedly installed on the top of the inner wall of the machine base 1, a movable tube 41 is movably installed inside the fixed tube 4, a pre-pressing block 42 is integrally formed at the bottom of the movable tube 41, a push rod 5 is fixedly connected to the telescopic end of the stroke cylinder 3, and a fixed block 51 is fixedly installed at the bottom of the push rod 5;

[0026] The stator part of the motor is placed in the placement groove 24 opened on the top of the electric turntable 2, and the rotor part and the stator part can be pressed and assembled through the fixing block 51 at the bottom of the base 1. After the stator part and the rotor part of the motor are pressed together, they are fixed by bolts, which is a prior art solution and will not be described in detail here.

[0027] The stator of the motor is partially placed in the placement groove 24 at the top of the electric turntable 2. The stator presses down the positioning block 27, so that the top opening of the clamping plate 22 rotating inside the mounting column 21 is automatically closed, and the motor stator is pre-positioned. The rotor is placed on the top of the stator and the telescopic end of the stroke cylinder 3 drives the push rod 5 and the fixing block 51 to synchronously press down the movable tube 41 in the fixed tube 4. The fixing block 51, in cooperation with the positioning spring 44, can drive the pre-pressing block 42 to press down, so that the stator and the rotor are pre-positioned on the positioning seat 23. When the position of the stator and rotor mounting bolts needs to be reversed, the electric turntable 2 can be rotated for fine adjustment, and the pre-pressing block 42 and the top movable tube 41 and the fixed tube 4 can rotate synchronously, so that the bolt position can be reversed to a suitable angle, which is more convenient for assembling the stator and the rotor in the motor.

[0028] After the motor rotor and stator are assembled on the top of the electric turntable 2, and the stroke cylinder 3 and the bottom fixing block 51 of the telescopic end rod 5 release the pressed positioning of the stator and the rotor, the assembled motor structure can be lifted upward from the placement groove 24, and the reset spring 26 can be reset elastically so that the positioning seat 23 can be reset upward. At this time, the four groups of clamps 22 can expand outward along the inner edge of the mounting column 21, so that the assembled motor part can be directly removed from the four groups of clamps 22, thereby eliminating the need to release the positioning of the motor stator, and the motor assembly efficiency is higher.

[0029] Among them, a buffer groove 25 is opened on the top of the electric turntable 2, and a reset spring 26 is fixedly installed in the inner wall of the buffer groove 25. The bottom end of the positioning block 27 is a convex structure. The bottom end of the positioning block 27 slides in the inner wall of the buffer groove 25. The bottom end of the positioning block 27 is fixedly connected to the top of the reset spring 26. A placement groove 24 is opened on the top of the positioning seat 23. The positioning seat 23 is a truncated cone structure. The positioning seat 23 slides between four groups of clamping plates 22 and is placed in the placement groove 24 at the top of the electric turntable 2 through the motor stator part. The stator presses down the positioning block 27, so that the top opening of the clamping plate 22 rotating inside the mounting column 21 is automatically closed, and the motor stator is pre-positioned. In this way, after the stator and the rotor in the motor are assembled, the motor assembly structure can be directly removed from the placement groove 24.

[0030] Among them, a device groove 43 is opened at the bottom of the pre-loading block 42, and the fixing block 51 is located in the inner wall of the device groove 43. A positioning spring 44 is rotatably installed between the inner wall of the device groove 43 and the fixing block 51. The bottom surface height of the fixing block 51 is less than the bottom height of the pre-loading block 42. The fixed tube 4 and the movable tube 41 are both hollow cylindrical structures. The push rod 5 movably penetrates the inner wall of the movable tube 41 and extends to the top of the electric turntable 2. When the rotor is placed on the top of the stator, the push rod 5 and the fixing block 51 can be driven by the telescopic end of the stroke cylinder 3 to synchronously press down the movable tube 41 in the fixed tube 4. The fixing block 51, with the cooperation of the positioning spring 44, can drive the pre-loading block 42 to press down, so that the stator and the rotor are pre-positioned on the positioning seat 23. When the position of the stator and rotor mounting bolts needs to be reversed, the electric turntable 2 can be rotated for fine adjustment, and the pre-loading block 42 and the top movable tube 41 and the fixing tube 4 can be rotated synchronously, so that the bolt position can be reversed to a suitable angle, which is more convenient for assembling the stator and the rotor in the motor.

[0031] Working principle: When assembling the stator and rotor in the motor, first place the stator part of the motor in the placement slot 24. At this time, the stator presses down the positioning block 27, so that the top opening of the rotating clamping plate 22 inside the mounting column 21 is automatically closed;

[0032] Then, the telescopic end of the stroke cylinder 3 drives the push rod 5 and the fixed block 51 to synchronously press down the movable tube 41 in the fixed tube 4. The fixed block 51, in cooperation with the positioning spring 44, can drive the pre-pressing block 42 to press down, so that the stator and the rotor are pre-positioned on the positioning seat 23. When the position of the stator and rotor mounting bolts needs to be reversed, the electric turntable 2 can be rotated for fine adjustment, and the pre-pressing block 42 and the top movable tube 41 and the fixed tube 4 can be rotated synchronously, so that the bolt position can be reversed to a suitable angle, which is more convenient for assembling the stator and the rotor in the motor.

[0033] Finally, when the stroke cylinder 3 continues to extend downward, the push rod 5 and the bottom fixing block 51 can press and position the stator and rotor parts of the motor. At this time, the bolts of the connecting parts can be assembled;

[0034] Then, after the motor rotor and stator are assembled on the top of the electric turntable 2, the stroke cylinder 3 and the bottom fixing block 51 of the telescopic end rod 5 release the pressed positioning of the stator and the rotor, the assembled motor structure can be lifted upward from the placement slot 24, and the reset spring 26 can be reset elastically so that the positioning seat 23 can be reset upward. At this time, the four groups of clamps 22 can expand outward along the inner edge of the mounting column 21, so that the assembled motor part can be directly removed from the four groups of clamps 22, thereby eliminating the need to release the positioning of the motor stator, and the motor assembly efficiency is higher.

[0035] Although the embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes and modifications may be made to the embodiments without departing from the principles of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
