Problems solved by technology

[0002] The inner and outer diameters of the stator core of large motors are large, the inner diameter is φ600~φ800, the external diameter is φ120~φ1500, and the length is 800~1100. At the same time, the precision requirements are high, especially the requirements for concentricity, cylindricity and groove flatness. The original stillborn tooling cannot meet the size requirements after lamination due to the large gap between the inner diameter of the shaft and the punch

Embodiment Construction

[0019] The present invention will be described in further detail below in conjunction with the accompanying drawings and specific embodiments.

[0020] The present invention is a large-scale motor lamination tooling. The cylindrical body 4 is line-cut to process 4 rectangular holes equally divided on the circumference, and the groove shape is correspondingly cut out. The outer diameter of the cylindrical body is 20mm smaller than the inner diameter of the stator punch, 4 One end surface of one wedge-shaped plate 7 is processed into a 5-degree inclined surface, and four 5-degree inclined-plane grooves are processed on the upper circumference of the mandrel 6. The wedge-shaped plate 7 is slidingly matched with the inclined surface of the mandrel 5, and the four wedge-shaped plates 7 are embedded in the cylinder. In the rectangular hole; the surface corresponding to the wedge-shaped block slope is connected with the tension plate 5, and the radius of the outer arc surface of each ...

Abstract

The invention relates to the technical field of motor stator laminations, in particular to an overlying tool for a large motor stator iron core. A vertical wedge-shaped expander structure is adopted in the overlying tool design. Four equant rectangular holes are formed in a cylinder, groove shapes are correspondingly formed through cutting, one end face of each of four wedge-shaped plates is machined into a 5-degree slope, four grooves with 5-degree slopes are machined in a spindle in an equant mode, and the wedge-shaped plates are in slide fit with the slopes of the spindle and embedded in the rectangular holes of the cylinder; a pull rod is connected to the top of the spindle, and the spindle can move up and down under the action of an adjusting nut to drive four tensioning plates to synchronously stretch or retract in the circumferential direction so that laminations can be positioned centrally and break away.

Description

technical field [0001] The invention relates to the technical field of motor stator core chips, in particular to a large-scale motor stator core lamination tooling. Background technique [0002] The inner and outer diameters of the stator core of large motors are large, the inner diameter is φ600~φ800, the external diameter is φ120~φ1500, the length is 800~1100, and the precision requirements are high, especially the requirements for concentricity, cylindricity and groove flatness. The original stillborn tooling cannot meet the size requirements after lamination due to the large gap between the inner diameter of the shaft and the punch. Contents of the invention [0003] The purpose of the present invention is to design lamination tooling to meet the production needs of various large-scale motor stator stamping laminations and welding into qualified stator cores. [0004] The technical scheme adopted by the present invention is: design the lamination tooling, adopt the ve...
