Assembling workbench for rotor and stator of servo motor

Abstract

The invention discloses an assembling workbench for a rotor and a stator of a servo motor. The assembling workbench comprises a base, a rotor three-jaw chunk, a stator moving device and a cylinder moving device are arranged on the base, the stator moving device and the cylinder moving device respectively comprise a motor supporting base, a motor, lead screw supporting bases, a lead screw, a lead screw sleeve and a coupler, the motor is fixed to one side of the motor supporting base, a sliding rail is arranged at the upper end of the motor supporting base, the lead screw supporting bases are located at the two ends of the lead screw, the lead screw is connected with the motor through the coupler, the lead screw is sleeved with the lead screw sleeve, the upper end of the lead screw sleeve of the stator moving device is connected with a stator platform, and the upper end of the lead sleeve of the cylinder moving device is connected with a cylinder assembly. Compared with the prior art, the assembling workbench for the rotor and the stator of the servo motor has the advantages that after the stator is arranged on the platform, the center of the stator is coaxial with the center of the rotor, the rotor is supported through the cylinder and a rotor support, and the rotor is prevented from dropping due to gravity.

Description

technical field [0001] The invention relates to a servo motor stator and rotor assembly workbench. Background technique [0002] In the current permanent magnet AC servo motor, the rotor structure has two types: built-in magnet steel and surface-mounted magnet steel. Because the surface-mounted structure is simple and the workmanship is good, the rotor of the permanent magnet AC servo motor often adopts the surface-mounted structure, which is It is required to strengthen the magnetic steel on the outer surface of the rotor. The current reinforcement method is to wrap a latitude-free belt outside the rotor magnetic steel or to cover the stainless steel ring. The stainless steel ring is relatively simple, but when the motor is working, the stainless steel ring will be induced. The eddy current causes the temperature rise of the motor to increase. Therefore, the surface-mounted rotors usually use winding latitude-free tape to reinforce the magnetic steel; although winding the ...

[0002] In the current permanent magnet AC servo motor, the rotor structure has two types: built-in magnet steel and surface-mounted magnet steel. Because the surface-mounted structure is simple and the workmanship is good, the rotor of the permanent magnet AC servo motor often adopts the surface-mounted structure, which is It is required to strengthen the magnetic steel on the outer surface of the rotor. The current reinforcement method is to wrap a latitude-free belt outside the rotor magnetic steel or to cover the stainless steel ring. The stainless steel ring is relatively simple, but when the motor is working, the stainless steel ring will be induced. The eddy current causes the temperature rise of the motor to increase. Therefore, the surface-mounted rotors usually use winding latitude-free tape to reinforce the magnetic steel; although winding the latitude-free tape can avoid increasing the temperature rise of the motor due to eddy currents, when assembling, due to the fixed The attraction between the rotors, if there is no equipment to ensure the concentricity of the stator and rotor during assembly, the stator core will easily scratch the non-woven belt, which will cause scratching noises when the motor is running, and there will also be magnetic steel falling off, and the motor will fail Hidden dangers
