Problems solved by technology

If you continue to use the chute core press-fitting method for full-circle punches to press-fit the fan-shaped punches, the fan-shaped punches may be staggered under high pressure, thus affecting the stacking of the chute fan-shaped punches Accuracy, and when stacking fan-shaped punches, it is necessary to align the chute one by one, which reduces the press-fitting efficiency

Abstract

The invention provides a press-fitting tool which is used for press-fitting fan-shaped punching sheets of a skewed slot stator core and comprises a stator bracket and at least one skewed slot positioning device, wherein the skewed slot positioning devices are installed on the stator bracket and are matched with a skewed slot of a stator core to be press-fitted. When the fan-shaped punching sheets are press-fitted, the skewed slot positioning devices are used for positioning the fan-shaped punching sheets. Accordingly, the invention further provides a press-fitting method. With the press-fitting tool and the press-fitting method, the laminating precision of the skewed slot fan-shaped punching sheets and the press-fitting efficiency can be improved.

Description

technical field [0001] The invention relates to the technical field of iron core press assembly, in particular to a press assembly tool and a press assembly method, which are used for press assembly of fan-shaped punching pieces of a skewed stator core. Background technique [0002] The motor chute technology has a significant weakening effect on the additional torque, noise, vibration and additional loss of the motor, and is generally used in the field of small and medium-sized motors. For small and medium-sized motors, the stator punching of the motor adopts full-circle punching, and the traditional chute core press-fitting method is also designed for full-circle punching. [0003] With the continuous increase of the motor unit capacity and the outer diameter of the stator punching, the stator punching of the motor is no longer suitable for the manufacture of full-circle punching, but is spliced ​​by fan-shaped punching. If you continue to use the chute core press-fitting...
