[0004] Generally, the stator is fixed in the casing through interference fit. When installing, the rotor needs to pass concentrically through the inner hole of the stator. Therefore, the magnetic steel on the outer surface of the rotor will attract the inner wall of the stator when passing through. The assembly method in the prior art It's very simple: the assembler holds the rotor and puts it directly from top to bottom to pass through the inner hole of the stator. During this process, the magnetic steel will be instantly attracted to the inner wall of the stator (in fact, the inner wall of the stator core), which will bring a strong impact to the magnetic steel. The magnetic steel is easy to break, and it is easy to pinch the hands of the assembly, which is dangerous, and it needs to be adjusted continuously during installation, and the work efficiency is low, which needs to be improved

The invention discloses an assembling tool for a stator and a rotor of a small-sized servo motor. The assembling tool comprises a fixed seat, a front end cover, a machine shell, a stator, a hoisting frame, a rear end cover and a rotor, wherein the rotor comprises a rotating shaft and magnetic steels uniformly distributed on the surface of the rotating shaft, height adjusting devices are uniformlydistributed on the fixed seat along the circumferential direction, isolation devices are arranged on the upper end surfaces of the height adjusting devices and comprise wiring harnesses and isolationstrips, the isolation strips are clamped between adjacent magnetic steels, the lower ends of the isolation strips extend out of the lower ends of the magnetic steels, strip-shaped iron block slots aresymmetrically formed in two sides of the isolation strips, strip-shaped iron blocks are tightly and cooperatively arranged in the strip-shaped iron block slots, and each strip-shaped iron block is attracted with the corresponding magnetic steel; and second arc-shaped protruded parts are arranged on one sides, far from the rotating shaft, of the isolation strips and are laminated to the inner wallof the rotor when the rotor vertically moves downwards, and the isolation strips are prepared from polytetrafluoroethylene. According to the assembling tool, the attraction between the stator and therotor is avoided during the assembly, the working efficiency is high, and the assembly is safe and reliable.
Description
technical field [0001] The invention relates to the technical field of motor stator and rotor assembly, in particular to an assembly tool for a stator and a rotor of a small servo motor. Background technique [0002] With the continuous improvement of the performance of permanent magnet materials and the development of motor technology, servo motors have been widely used in various fields of the national economy. Servo motors have the characteristics of high power density, high precision, and stable operation. [0003] The stator and the rotor are important parts of the servo motor. The stator includes the stator core and the stator winding. The stator core is formed by connecting multiple stator punching groups end to end in sequence. Each stator punching group is composed of multiple silicon steel sheets stacked together. The stator winding is wound on the stator core; the rotor includes a rotating shaft and several magnetic steels uniformly distributed on the surface of t...
