Abstract

The invention discloses a buckle piece lamination device of a conical stator punching sheet. The buckle piece lamination device comprises a stator punching sheet lamination device, a leveling device and a buckle piece lamination device, wherein an expansion sleeve, lower external cone tools and a stator punching sheet fixing seat are arranged on the stator punching sheet lamination device and are in clearance fit with one another, a trapezoidal plate is fixedly arranged on the stator punching sheet fixing seat and is arranged vertically, inclined surfaces of two sides of the trapezoidal plate can be inserted into two corresponding inner grooves of each stator punching sheet, the leveling device comprises a flattening tool, an upper internal cone tool sleeves the flattening tool, the flattening tool and the upper internal cone tool can downwards press on the stator punching sheet lamination device under the push of a leveling air cylinder, the buckle piece lamination device comprises a roller capable of transversely moving and a roller air cylinder, the roller transversely mover under the driving of the roller air cylinder, and an upper end and a lower end of a buckle piece are respectively bent and are attached onto an upper surface and a lower surface of a conical stator so that the stator punching sheets forming the conical stator can be fixed together. The buckle piece lamination device has the advantages of good perpendicularity in each stator punching sheet, stack compactness, stator inner groove orderliness and high appearance cylindricality.

Description

technical field [0001] The invention belongs to the technical field of lamination of stator punching sheets of a motor, and in particular relates to a lamination device of conical stator punching sheets and clips. Background technique [0002] Conical rotor three-phase asynchronous motor stator inner diameter of each stamping is different, so its lamination process is quite special. The commonly used method is that there are three custom-made round rods in the stacking mold, and the punching pieces are put into the mold, and the positioning is made by the arc surface at the bottom of the punching slot and the cylindrical surface of the round rod, and the punching pieces are in order Put it into the mold, the mold is put into the hydraulic press, the shape of the punching sheet is tightly wrapped under the action of the mold outsourcing slider, and the buckle is fastened by the action of the roller, and the whole process is completed. With this mold structure method, the pos...
