Attaching device and attaching method for motor rotor and stator

Abstract

The invention discloses an attaching device for a motor rotor and a stator. The attaching device comprises a cantilever attaching machine (A), a rotor pipeline (4) and a stator pipeline (6), wherein the cantilever attaching machine (A) comprises a main girder device (1), a transverse U-shaped main girder (2) and a transverse L-shaped secondary cantilever (3); the transverse U-shaped main girder (2) is located at one side (for example, right side) of the main girder device (1); the transverse L-shaped secondary cantilever (3) is located at the other side (for example, left side) of the main girder device (1); the rotor pipeline (4) comprises a rotor input pipeline (401); the stator pipeline (6) comprises a stator pipeline (601), a stator center adjusting platform (602) and a rotor stator and stator assembly output pipeline (603); the stator pipeline (6) is arranged below the U-shaped main girder (2); and the rotor pipeline (4) is arranged below the L-shaped secondary cantilever (3). The attaching device can bear assembly of large and medium-sized workpieces; according to the attaching device, the bearing weight is increased; the stability is improved; and the accuracy is ensured.

Description

technical field [0001] The invention relates to the technical field of mechanical manufacturing, in particular to an automatic assembly device for large and medium-sized rotors and stators or a suspension beam assembly machine. The assembly machine or assembly equipment is used for the automatic assembly or assembly of rotors and stators, especially for the automatic assembly or assembly of large and medium-sized rotors and stators. Background technique [0002] With the continuous development of science and technology, the progress of society, and the vigorous promotion of clean energy (such as wind energy, etc.), the use of large and medium-sized motors is becoming wider and wider. Different from the design and standardized process of micro and small motors, large and medium motors often need to go through complex and strict inspection procedures before leaving the factory to ensure product safety and reliability. The unit price of large and medium-sized motors is relativ...

AI Technical Summary

Problems solved by technology

At present, most of the rotor and stator automatic assembly machines on the market adopt a structure in which the rotor is moved and assembled into the stator by clamping the front and rear of the single arm. Elastic deformation, the cantilever beam cannot be freely adjusted up and down, single-set assembly production

The disadvantages are: 1. The rigidity of the combined machine itself is not enough to meet the rigidity requirements of the large-tonnage motor rotor, and the operation is unstable

2. The suspension beam of the assembly machine cannot be freely adjusted to control the elastic deformation to make compensation adjustments. It is difficult to guarantee the synchronization of operation. It cannot meet the needs of multi-spec and multi-type motors during assembly, which is likely to cause wear and affect the normal use of the equipment.

3. Most of the rotors and stators are loaded by manual or semi-automatic equipment, which cannot be produced in an assembly line, which seriously affects the production efficiency

4. Due to the small air gap between the rotor and the stator, there are high requirements for workers to operate during assembly, and during the process of assembling the rotor, workers cannot observe the condition of the stator and rotor in real-time monitoring and detection, which may easily cause the stator and rotor to rub against each other and damage the insulation of the rotor Layer, there is a large quality hidden danger, affecting the overall quality of the motor

5. Since all operations are installed manually, it cannot be automated and intelligently produced. Not only is the work efficiency low, but there are also certain safety hazards for workers
