Problems solved by technology

[0003] The front and rear bearing positions and front and rear oil seal positions of the motor rotor are usually processed by a grinding machine. During processing, it is necessary to manually align the two ends of the workpiece (rotor to be processed) with the two clamping heads on the grinding machine, and then drive the two clamping heads Clamp the workpiece, and then manually lock the workpiece, so that the workpiece can rotate synchronously with the power output shaft of the grinding machine. The clamping of the workpiece is very inconvenient, thereby reducing the processing efficiency, and it is impossible to realize automatic loading and unloading

Abstract

The invention relates to the technical field of motor manufacturing, in particular to a motor rotor grinding device to achieve the technical purpose of improving machining efficiency. The motor rotor grinding device comprises two grinding machines arranged on the left side and the right side in a spaced mode, a clamping disc is fixed to a power output shaft of the left grinding machine, the right grinding machine is provided with a tailstock ejector head capable of moving left and right, and the right grinding machine is provided with an ejector head drive component used for driving the tailstock ejector to move left and right. The clamping disc is provided with a shifting disc capable of moving left and right and synchronously rotating along with the clamping disc. The shifting disc is installed on the clamping disc through a plurality of shifting disc guiding columns sleeved with shifting disc springs. The middle of the shifting disc is provided with a boss protruding rightwards, the boss is used for clamping a workpiece, the center of the shifting disc is provided with a through hole, the through hole is internally provided with a fixed ejector head movably matched with the shifting disc, the fixed ejector head is fixedly connected with the clamping disc, and the center axis of the fixed ejector head coincides with the center axis of the tailstock ejector head. The motor rotor grinding device is suitable for grinding bearing positions and oil seal positions of a motor rotor.

Description

technical field [0001] The invention relates to motor manufacturing technology, in particular to a technology of a motor rotor grinding device. Background technique [0002] The motor is mainly composed of a stator, a rotor, a casing, and an end cover. The air gap between the stator and the rotor is very small, generally between 0.25 and 0.8mm. To ensure that the concentricity of the rotor and the stator is mainly guaranteed by the end covers at both ends. In addition, the machining accuracy of the rotor itself is more important, especially the concentricity requirements of the front and rear bearing positions and shaft extension, which directly affect the performance of the motor. And the air gap between the stator and the rotor. After the motor is energized, the stator winding generates a magnetic field to drive the rotor to rotate at a high speed. Therefore, the machining accuracy of the rotor determines the main performance of the motor such as noise, vibration, and star...
