Description

Technical Field

[0001] The present invention relates to the technical field of motor assembly, and in particular to a motor stator assembly device and an assembly method. Background Art

[0002] The stator of a motor consists of a base and a winding stator core, both of which are circular in shape. The inner circle of the base is inserted into the outer circle of the winding stator core, and the fit is interference fit. For the stator assembly of a medium-sized motor, a special hoist is usually used to lift the winding stator core and place it vertically on a workbench. The base is then heated and lifted and inserted into the winding stator core. Before assembly, the winding stator core is placed horizontally on a workstation. A special flipping machine is required to flip it from a horizontal state to a vertical state. Due to the large number of types and specifications of motors, the inner and outer dimensions of the winding stator core of each specification are different. Therefore, a special hoist is required for each specification. This results in a large number of special stator hoists being required, the stator hoists taking up storage space when stored on site, and the complicated operation steps of the stator assembly process. To this end, we propose a motor stator assembly device and assembly method. Summary of the Invention

[0003] Based on the technical problems existing in the background technology, the present invention proposes a motor stator assembly device and assembly method, which has the characteristics of a set of motor stator assembly devices suitable for assembling motor stators of multiple specifications. It solves the problem in the prior art that a large number of special stator hangers are required, and the stator hangers occupy storage space when stored on site, resulting in complicated operating steps in the stator assembly process.

[0004] The present invention provides the following technical solutions:

[0018] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0019] See also Figure 1 , the present invention provides a technical solution:

[0020] A motor stator assembly device includes a machine base 2 and a winding stator core 3, and also includes a lifting frame 1. The lifting frame 1 is provided with a height-adjustable lifting seat 13. The lifting frame 1 is installed with a support rod 10. The support rod 10 is provided with a support plate 4 that can be expanded and contracted. The support rod 10 and the support plate 4 are inserted into the interior of the winding stator core 3 and fixed to the winding stator core 3 by adjusting the expansion and contraction of the support plate 4. The lifting frame 1 is also provided with a vertical support plate 17 that supports the winding stator core 3. The position of the vertical support plate 17 relative to the lifting frame 1 can be adjusted. The vertical support plates 17 are two pieces and can be moved on the lifting frame 1. By moving the positions of the two vertical support plates 17, the outer diameter of the winding stator core 3 of different specifications and models can be adapted.

[0021] One end of the support plate 4 is connected to a fixed link seat 15 via a connecting rod 5, and the other end of the support plate 4 is connected to a sliding link seat 6 via a connecting rod 5. The fixed link seat 15 is fixed to the support rod 10, and the relative position between the sliding link seat 6 and the support rod 10 can be adjusted. By adjusting the relative position between the sliding link seat 6 and the support rod 10, the support plate 4 can be opened and closed.

[0022] The sliding link seat 6 is connected to the nut 11 via the pin 7, and the support rod 10 is connected to the screw 8 via the pressure plate 9. By rotating the screw 8, the nut 11 moves along the support rod 10, thereby driving the sliding link seat 6 to move along the support rod 10. By rotating the screw 8, the relative position between the screw 8 and the nut 11 is adjusted, thereby adjusting the relative position between the sliding link seat 6 and the support plate 4.

[0023] The support plate 4, the connecting rod 5, the sliding connecting rod seat 6 and the fixed connecting rod seat 15 form a four-bar linkage, and the number of the four-bar linkage is no less than 2. The number of the four-bar linkage is preferably 3.

[0024] The lifting base 13 is fixed to the lifting frame 1 via a latch 12. A rotatable side pull ring 14 is provided on the side of the lifting base 13. Since the side pull ring 14 has a rotatable function, after the winding stator core 3 is lifted, the motor stator assembly device and the winding stator core 3 are flipped from a horizontal position to a vertical position by rotation.

[0025] Lifting frame 1 is equipped with positioning blocks 16, which contact the end surface of base 2. The height of positioning blocks 16 is adjustable. The height of positioning blocks 16 needs to be adjusted according to the alignment dimensions of base 2 and winding stator core 3. After heating, base 2 is lifted vertically and inserted into winding stator core 3.

[0026] When using the above-mentioned motor stator assembly device to assemble the motor stator, first rotate the screw 8 so that the outer diameter of the support plate 4 is smaller than the inner diameter of the winding stator core 3. Adjust the position of the lifting seat 13 so that it coincides with the center of gravity of the motor stator assembly device. Lift the motor stator assembly device and flip it from a vertical state to a horizontal state. Insert the support plate 4 of the motor stator assembly device into the inner diameter of the winding stator core 3. Adjust the vertical support plate 17 so that its outer diameter is smaller than the outer diameter of the winding stator core 3. The end face of the vertical support plate 17 contacts the end face of the winding stator core 3. Rotate the screw 8 so that the outer diameter of the support plate 4 contacts the inner diameter of the winding stator core 3. Adjust the position of the lifting seat 13 so that it coincides with the common center of gravity of the motor stator assembly device and the winding stator core 3. Lift the motor stator assembly device and the winding stator core 3, flip them from a horizontal state to a vertical state, and place them on the workbench. Adjust the height of positioning block 16 according to the positioning dimensions of base 2 and winding stator core 3. Lift the heated base 2 vertically and insert the winding stator core 3. Ensure the end face of base 2 contacts positioning block 16. After base 2 cools, rotate screw 8 to loosen support plate 4. Lift the stator and proceed to the next process.

[0027] The present invention utilizes a single motor stator assembly device that can be used to assemble motor stators of various specifications. The device also incorporates a built-in flipping function, eliminating the need for separate flipping equipment. The device simplifies operation, reduces assembly time, and improves efficiency. It also reduces the footprint of on-site tooling and mold storage.
