Description

Horizontal assembly method of vertical permanent magnet motor

The present invention relates to a motor assembly method, and more particularly to a horizontal assembly method of a vertical permanent magnet motor.

Generally speaking, when assembling the stator assembly and the rotor assembly of an existing permanent magnet motor, since the stator assembly is provided with an electromagnet and the rotor assembly is provided with a magnet, an air gap needs to be provided during the assembly of the two to prevent the rotor assembly and the stator assembly from being hindered by the influence of magnetic attraction.

As mentioned above, the air gap is mainly set between the rotor assembly and the stator assembly to prevent the rotor assembly from being adsorbed to the stator assembly due to magnetic force. When the rotor assembly and the stator assembly are assembled, the user can remove the air gap. However, in order to remove the air gap from the assembled permanent magnet motor, it is necessary to drill holes on the bracket in advance, thereby relatively increasing the manufacturing cost of the permanent magnet motor. In particular, the larger the size of the motor, the more difficult it is to assemble.

In addition, although drilling holes on the bracket can effectively remove the air gap sheet, the size of the bracket will change with the size of the permanent magnet motor, resulting in different drilling positions on the bracket. Operators need to adjust the drilling positions for brackets of different sizes, which is very inconvenient.

Permanent magnet motors can be divided into horizontal and vertical types. The main difference between horizontal and vertical permanent magnet motors is that the base of the horizontal permanent magnet motor is at the frame, so it is usually placed horizontally when used, while the base of the vertical permanent magnet motor is at one end of the frame, so the frame can be placed upright when used.

In the prior art, a method for assembling a horizontal permanent magnet motor has been developed. However, this method mainly involves placing the frame of the permanent magnet motor on a slidable carrier, passing the frame through the carrier through a push pin, and then placing the rotor assembly between two push pins. Finally, the carrier is used to sleeve the frame onto the rotor assembly to complete the assembly. However, since this method fixes the frame on the carrier, it is more suitable for a horizontal permanent magnet motor with a base on the frame. A vertical permanent magnet motor cannot be assembled using this method because the base is at one end of the frame and is not easily fixed on the carrier. This is very inconvenient.

In view of the fact that in the prior art, although the existing technology has developed an assembly method that can assemble a permanent magnet motor, the existing assembly method is mainly to fix the frame of the permanent magnet motor on the carrier, and therefore is more suitable for assembling a horizontal permanent magnet motor whose base is set at the frame, while the vertical permanent magnet motor is not suitable because the base is at one end of the frame, and can only be assembled in a more traditional way, which is very inconvenient; therefore, the main purpose of the present invention is to provide a horizontal assembly method for a vertical permanent magnet motor, which can fix the frame of the vertical permanent magnet motor on the carrier, and then assemble it in a horizontal form.

The present invention solves the problems of the prior art by adopting a necessary technical means to provide a horizontal assembly method of a vertical permanent magnet motor, comprising the following steps (A) to (F).

Step (A) is to prepare a motor assembly machine, the motor assembly machine comprising a machine body, a fixed abutting assembly, a movable abutting assembly and a sliding platform, the fixed abutting assembly and the movable abutting assembly are arranged at two ends of the machine body, and the fixed abutting assembly has a fixed pin extending toward the movable abutting assembly, and the movable abutting assembly is provided with a fixed pin extending toward the movable abutting assembly. The push assembly has a movable push pin extending toward the fixed push assembly. The sliding platform is movably arranged on the machine body along a sliding path between the fixed push assembly and the movable push assembly. The sliding platform includes a platform plate parallel to the moving path and a vertical plate perpendicular to and fixed to the platform plate. The platform plate is provided with a frame fixing block.

In step (B), a fixed frame module is first sleeved on the fixed pin and then fixed to the vertical plate and the frame fixing block, and a bracket is movably sleeved on the movable pin.

Step (C) disposes a rotor assembly between the fixed ejector pin and the movable ejector pin, and aligns two ends of a rotating shaft of the rotor assembly with the movable ejector pin and the fixed ejector pin respectively.

Step (D) controls the movable ejector pin to extend toward the fixed ejector pin, so that two ends of the rotating shaft are respectively pressed and fixed by the movable ejector pin and the fixed ejector pin.

Step (E) controls the sliding platform to move along the sliding path toward the movable abutment assembly so that the stator frame module is sleeved on the rotor assembly.

Step (F) assembles and fixes the bracket to the stator frame module to assemble a vertical permanent magnet motor.

In an auxiliary technical means derived from the above-mentioned necessary technical means, the step (B) further includes the following steps (B1) and (B2).

Step (B1) is to sleeve the stator frame module onto the fixed pin first and then fix it onto the vertical plate and the frame fixing block. Step (B2) is to movably sleeve the bracket onto the movable pin.

In an auxiliary technical means derived from the above necessary technical means, the step (B) further includes the following steps (B1) and (B2). Step (B1) is to movably sleeve the bracket on the movable pin. Step (B2) is to first sleeve the stator frame module on the fixed pin and then fix it to the vertical plate and the frame fixing block.

In an auxiliary technical means derived from the above necessary technical means, a step (G) is further included after the step (F), and the step (G) is to control the movable top needle to move away from the rotating shaft to release the fixation of the rotating shaft.

In an auxiliary technical means derived from the above-mentioned necessary technical means, the step (C) is to use a sling to suspend the rotor assembly so that the rotor assembly is suspended between the fixed thimble and the movable thimble.

In an auxiliary technical means derived from the above-mentioned necessary technical means, the movable ejector pin is a manually retractable movable ejector pin, and in the step (D), the movable ejector pin is manually controlled to extend toward the fixed ejector pin.

As described above, the present invention is mainly to prepare a motor assembly machine with a sliding platform, and the sliding platform also has a vertical plate and a frame fixing block, so that the stator frame module of the vertical permanent magnet motor can be locked on the vertical plate, and supported by the frame fixing block, and then fixed on the sliding platform. Thereby, after the rotor assembly is fixed by the fixed pin and the movable pin, the stator frame module can be sleeved on the rotor assembly through the movement of the sliding platform, and the vertical permanent magnet motor can be assembled after the bracket is locked on the stator frame module.
