An operating device for assembling a surface-mounted permanent magnet rotor

Abstract

The invention relates to the technical field of mechanical equipment, in particular to an operation device used for assembling a surface-mounted permanent-magnetic rotor. A surface-mounted permanent magnetic rotor comprises a rotor core shaft and multiple magnetic bodies. The operation device comprises an end cover mechanism and a positioning press plate. The end cover mechanism comprises guiding parts arranged around a circumference and a positioning part used for installing and positioning the rotor core shaft. In an assembly structure, through the positioning and installation of the positioning part and the rotor core shaft, the axis of the guide part and the axis of the rotor core shaft are on the same line. The positioning press plate is installed and positioned on the guide part and capable of switching positions along a set track of the guide part. The inner wall of the positioning press wall is used for being pressed against and positioned to the magnetic bodies attached to the outer wall of the rotor core shaft. Through the above structure arrangement, in the assembly process, all magnetic bodies can be precisely pressed and positioned from the external side through the positioning press plate before being fixedly installed, therefore, by applying the operation device, the assembly convenience and assembly precision of the surface-mounted permanent-magnetic rotor can be remarkably improved.

Problems solved by technology

[0004] In the prior art, the surface-mounted permanent magnet rotor used in the motor includes a rotor mandrel and a plurality of magnetic bodies attached to the side wall of the rotor mandrel, and the plurality of magnetic bodies are arranged in sequence along the circumference of the rotor mandrel. The polarities of the two adjacent magnetic bodies are oppositely set. For example, the N pole of a certain magnetic body is attached to the radially outer wall of the rotor core shaft, and its S pole is facing outward. Correspondingly, on both sides of the magnetic body, The magnetic body adjacent to it is that the S pole is attached to the radial outer wall of the rotor mandrel, and so on. When the magnetic body is attached to the circumferential surface of the rotor mandrel, the surface-mounted permanent magnet The magnetic body of the rotor is installed, and in the process of assembling the surface-mounted permanent magnet rotor, due to the above-mentioned structural setting requirements, that is, the polarities of the two adjacent magnetic bodies are reversed, therefore, before the installation is firm, , it is easy to cause the flipping phenomenon of the magnetic body due to magnetic attraction. When the previous magnetic body is installed, the N pole is set to face the outside. When the other adjacent magnetic body is not installed firmly, the other The S pole of the magnetic body is facing outward. Due to the effect of magnetic attraction, it is easy to cause the non-installed magnetic body to flip over, and then turn over and attract to the top surface of the firmly installed magnetic body, which causes inconvenience to the installation operation; and At the same time, for each magnetic body, it is necessary to set the longitudinal axis of each magnetic body parallel to the axial direction of the rotor core shaft in the structure, and the outer diameter of the annular contour formed by each assembled magnetic body needs to be consistent, otherwise Will cause the accuracy of the overall assembled motor to decrease

However, it is difficult to ensure the accuracy of the position and angle in the process of manual limit installation

[0005] In the above existing technologies, the defects of convenience and low installation accuracy in the assembly process of surface-mounted permanent magnet rotors are technical problems that need to be solved by those skilled in the art
