Description

Large-scale permanent magnet motor assembly fixture Technical Field The utility model belongs to the field of motor assembly, and particularly relates to a large permanent magnet motor assembly fixture. Background In the field of manufacturing large permanent magnet motors, precise assembly of bearings is a critical step in ensuring smooth operation of the motor and reducing vibration and noise. However, due to the large size of large permanent magnet motors, the required bearings are correspondingly increased in size, which undoubtedly increases the difficulty and complexity of assembly. The traditional assembly method mostly depends on manual operation, so that the efficiency is low, and the assembly precision and consistency are difficult to ensure. In order to solve the problem, various large-scale permanent magnet motor assembly tools appear on the market. However, these tooling devices often have a number of structural and functional disadvantages. For example, some tooling devices lack flexible adjustment mechanisms, and cannot be accurately adjusted according to the size and shape of the bearing, resulting in a failure of smooth installation or deviation of the bearing during assembly. In addition, some tooling equipment has an adjusting function, but an adjusting mechanism of the tooling equipment is complex in design and complex in operation, so that the assembly time is prolonged, and the assembly efficiency is reduced. In terms of detection, conventional assembly tools often lack an effective flatness detection mechanism. During the assembly of the bearing, if the matching surface of the bearing and the motor shaft or the bearing seat is uneven, vibration and noise can be generated in the operation process of the motor, and even the motor can be damaged. However, most of the existing tooling equipment is not provided with a flatness detection mechanism, or the accuracy of the flatness detection mechanism is not high, and deviation in the assembly process cannot be found and corrected in time.
