Permanent magnet motor block stator assembly tooling

Abstract

The invention discloses an assembling tool for a spliced stator of a permanent-magnet motor. The assembling tool comprises a base, wherein a central circular convex plate is arranged in the base; a core mold positioning spigot and a stator positioning spigot are sequentially arranged at the periphery of the central circular convex plate; convex plates and concave grooves with the same quantity as that of spliced stator grooves of the permanent-magnet motor are arranged and formed at intervals at the periphery of the base; a core mold is mounted on the central circular convex plate by matching of the core mold positioning spigot; when the spliced stator surrounds the core mold and is located on the convex plates at the periphery of the base, the lower end of the spliced stator is matched with the stator positioning spigot on the base; a platen is mounted on the core mold; the stator positioning spigot at the periphery of the platen is matched with the upper end of the spliced stator; the center of the base penetrates through a pressure rod bolt; the pressure rod bolt penetrates through a center hole of the platen, and then an upper limiting nut is mounted; a lifting lug is welded outside the upper limiting nut. After the assembling tool for the spliced stator of the permanent-magnet motor is used, inside and outside diameter tolerances of the stator after assembling can meet design requirements, so that an air gap of the permanent-magnet motor achieves a design requirement; assembling tolerances of the stator and a housing of the permanent-magnet motor are met.

Description

technical field [0001] The invention belongs to the technical field of permanent magnet motor processing auxiliary equipment, and relates to a permanent magnet motor assembly stator assembly tool, which is used for stator assembly of a permanent magnet motor with a block stator structure. Background technique [0002] The low-speed high-torque direct-drive permanent magnet motor used for belt conveyors is relatively large in size, and the utilization rate of circular punched silicon steel sheets is extremely low. In order to improve the utilization rate of the stator punching, the stator structure of the foil-type wound permanent magnet motor is adopted, that is, the stator adopts a block structure. The stator punching is processed and stacked with a special mold to form a stator block, such as figure 1 As shown, the yoke of each single-tooth stator block has an axial groove 18 on the side, and an axial protruding tooth 19 on the left side. The adjacent stator block passes ...
