Abstract

The invention discloses a geometric shape precision machining method for a hollow rotating shaft of a motor. The geometric shape precision machining method specifically comprises the following steps of 1, basic treatment of the rotating shaft and equipment; S2, selection and treatment of auxiliary materials; S3, high-order treatment of the auxiliary materials; S4, forming operation of the hollow rotating shaft; S5, polishing operation of the hollow rotating shaft; S6, dynamic polishing of the hollow rotating shaft; and S7, packaging. The invention relates to the technical field of hollow rotating shafts of motors. According to the geometric shape precision machining method for a hollow rotating shaft of a motor, the device can polish the hollow rotating shaft comprehensively under the condition that the hollow rotating shaft is kept in a static state and polish the hollow rotating shaft under the condition that the hollow rotating shaft operates at a high speed,so that the polishing comprehensiveness and uniformity of the hollow rotating shaft are greatly improved, the symmetry of the hollow rotating shaft during high-speed operation is improved, the geometric shape precision of the hollow rotating shaft of the motor is improved and meanwhile, the operating logic is clear, the method is clear and it is convenient for staff to machine.

Description

technical field [0001] The invention relates to the technical field of a hollow shaft of a motor, in particular to a method for machining the geometric shape precision of a hollow shaft of a motor. Background technique [0002] The motor is represented by the letter M in the circuit, and its main function is to generate driving torque. As a power source for electrical appliances or various machines, the generator is represented by the letter G in the circuit. Its main function is to use mechanical energy to convert electrical energy. Servo motors are widely used in various control systems. They can convert input voltage signals into mechanical output on the motor shaft, and drive the controlled components to achieve control purposes. Servo motors are divided into DC and AC. The earliest servo motors are general DC motors. When the control accuracy is not high, general DC motors are used as servo motors. Structurally speaking, a DC servo motor is a low-power DC motor. Its e...
