Stator winding glue spray positioning support turntable and stator winding glue spray method

Abstract

An adhesive spraying positioning support rotary table of a stator winding is characterized by comprising a support rolling disc, expansion rings and a rolling table, wherein the support rolling disc is arranged at two ends of the stator winding, the expansion rings are used for positioning an adhesive spraying position, the two expansion rings are expanded and attached onto two sides of the adhesive spraying position in the stator winding, the external diameter of the support rolling disc is larger than the external diameter of the stator winding, the support rolling disc is placed on the rolling table and is in contact with a rotatable rotation rod on the rolling table, the support rolling disc is driven to rotate on the rotation rod at a uniform speed by external power, so that the stator winding rotates uniformly. By the adhesive spraying positioning support rotary table, uniform and accurate spraying of glue is achieved, the thickness and position accuracy design requirement of a fluorosilicone adhesive surface is achieved, an adhesive spraying standard operation mode of the stator winding is formed, the efficiency and the quality of glue spraying operation are improved, and the quality of a motor stator is improved. The invention also provides an adhesive spraying method of the stator winding.

Description

technical field [0001] The invention relates to a stator winding glue spray positioning support turntable, which is used for stator winding glue spray and belongs to the technical field of motor manufacturing. The invention also relates to a stator winding glue spray protection method. Background technique [0002] In the motor stator insulation treatment process, it is necessary to spray fluorosilicone within a certain distance between the stator notch and the coil nose, so as to enhance the dustproof and sandproof performance of the motor, and improve the insulation and mechanical properties of the motor stator. This operation has strict requirements on the spraying thickness and position of fluorosilicone. The thickness accuracy is 0.3mm and the position accuracy is 1mm. It is difficult to ensure the thickness and accuracy of the sprayed glue in actual operation, and it is difficult to meet the design requirements, and the curing time of the glue is short. The fluidity is...

Problems solved by technology

[0006] The above existing patents are protective tooling for spraying, which is used to prevent fluorosilicone from flowing along the slot of the stator and position the glue spraying position. However, the thickness accuracy of fluorosilicone is difficult to control. Most of the colloid spraying operations are mastered by the experience of the sprayers. The standard is not high, and it is still difficult to meet the design requirements of thickness accuracy
