Description

Technical Field

[0001] This invention relates to the technical field of assembly, and more specifically to an assembly device for a high-voltage three-phase asynchronous motor. Background Technology

[0002] A high-voltage three-phase asynchronous motor is a type of induction motor that is powered by three-phase high-voltage alternating current. Because the rotor and stator rotating magnetic fields of a three-phase asynchronous motor rotate in the same direction but at different speeds, slip exists, hence the name "three-phase asynchronous motor." The rotor speed is lower than the rotating magnetic field speed. The rotor windings generate electromotive force and current due to the relative motion between them and the magnetic field, and interact with the magnetic field to produce electromagnetic torque, thus achieving energy conversion. Therefore, equipment is needed to assemble and install three-phase asynchronous motors, while also preventing deviations during assembly and addressing the issue of not being able to fix and assemble multiple models of three-phase asynchronous motors. Summary of the Invention

[0003] In view of the shortcomings mentioned in the above technical background, the purpose of this invention is to provide an assembly device for a high-voltage three-phase asynchronous motor.

[0006] Furthermore, four arrayed first concave bases are provided on one side of the support plate, and a first rotating rod is provided rotatably connected inside the first concave base. A first connecting rod is provided rotatably connected on the outer surface of the first rotating rod. Four arrayed second concave bases are provided on the other side of the support plate, and a second rotating rod is provided rotatably connected inside the second concave base.

A drive shaft is rotatably connected to one side of the support rod, and a sleeve is fixedly connected to the other side. A fastening screw shaft is housed within the sleeve. One end of the fastening screw shaft is fixedly connected to the drive shaft, and a second motor is fixedly connected to the other end of the drive shaft. A transmission belt is connected to the outer surface of the drive shaft, and a driven shaft is connected to the other end of the transmission belt. The driven shaft is fixedly connected to the symmetrically distributed fastening screw shafts. A second connecting rod is fixedly connected to one side of the support rod, and a third connecting rod is rotatably connected to the other end of the second connecting rod. The other end of the third connecting rod is rotatably connected to a second rotating rod.

[0010] Furthermore, the cover plate mounting mechanism includes a mounting base fixedly connected to the base plate. A third motor is rotatably connected to one end of the mounting base.

A U-shaped mounting plate is fixedly connected to one side of the other end of the second lead screw plate. A cover plate mounting groove is formed on the U-shaped mounting plate, and symmetrically distributed positioning holes are formed on both sides of the surface of the U-shaped mounting plate.

[0011] The beneficial effects of this invention are:

[0012] 1. This invention starts a first motor to drive a first bidirectional lead screw to rotate, causing the two first lead screw plates on the first bidirectional lead screw to move inward and outward simultaneously. The clamping plates on the first lead screw plates clamp and fix the motor to be assembled. At the same time, different models of motors can be clamped and fixed. The second sliding rods on both sides can play a sliding role.

[0013] 2. This invention achieves positioning by aligning the positioning rod with the positioning hole to prevent assembly deviation. Then, the hydraulic rod is activated to lower the support plate, while the third connecting rod drives the second connecting rod to move the support rod inward. When the sleeve is aligned with the screw on the cover plate, the second motor is activated to tighten the screw shaft. Attached Figure Description

A clamping plate 184 is fixedly connected to one end of the first screw plate 182, and two symmetrically distributed positioning rods 185 are located on one side of the clamping plate 184. When the operator starts the first motor 151, it drives the first bidirectional screw 181 to rotate, causing the two first screw plates 182 on the first bidirectional screw 181 to move simultaneously inward and outward. This allows the clamping plate 184 on the first screw plate 182 to clamp and fix the motor to be assembled, and it can clamp and fix motors of different models.

Then, the cover plate to be installed is placed into the cover plate mounting groove 334, and at the same time, the positioning rod 185 is aligned with the positioning hole 335 to achieve the positioning function and prevent the assembly from deviating.

[0025] Working principle:

[0026] The operator starts the first motor 151, which drives the first bidirectional lead screw 181 to rotate. This causes the two lead screw plates 182 on the first bidirectional lead screw 181 to move inward and outward simultaneously. The clamping plates 184 on the lead screw plates 182 clamp and fix the motor to be assembled. This method can clamp and fix motors of different models. The second sliding rods 1831 on both sides provide a sliding assistance function. Then, the operator starts the third motor 32, which drives the second bidirectional lead screw 331 to rotate. The U-shaped mounting plate 333 on the second bidirectional lead screw 331 is moved inward simultaneously, and the cover plate to be installed is placed into the cover plate mounting groove 334. At the same time, the positioning rod 185 is aligned with the positioning hole 335 to achieve the positioning function and prevent assembly deviation. Then, the hydraulic rod 14 is activated to lower the support plate 15. At the same time, the third connecting rod 26 drives the second connecting rod 25 to drive the support rod 24 to move inward simultaneously. When the sleeve 2411 is aligned with the screw on the cover plate, the second motor 242 is activated to tighten the screw shaft 2412.
