Description

TECHNICAL FIELD

[0001] The technical scheme relates to the motor technical field, and particularly relates to a stator core clamping sheet pressing equipment. BACKGROUND

[0002] In the process of processing the motor stator core, silicon steel sheets are stacked together, and then a clamping sheet is pressed and mounted on the side wall of the stator core by a clamping sheet machine.

[0003] The existing clamping sheet machine needs to manually put the sorted and quantified silicon steel sheets into the guide column of the clamping sheet machine, and then put the clamping sheet into the groove of the outer circle of the stator core, and then press and mount the clamping sheet in place by the clamping sheet machine, but the existing clamping sheet machine still has some deficiencies.

[0004] 1. When the existing stator clamping sheet is installed, the stator core needs to be adjusted by hand and transported to the pressing device, and then the clamping sheet is installed one by one on the side of the stator core by the machine. The stator core is fixed by the guide column of the machine, and when the clamping sheet is pressed to the side of the stator core, the stator core is single-sided stressed, which can cause the guide column to be single-sided stressed and deformed, affecting the installation of the clamping sheet and causing the clamping sheet to be installed obliquely or the end of the clamping sheet to be fixed, affecting the product yield.

[0005] 2. As disclosed in Chinese patent CN201820135743.3, an automatic forming machine for motor clamping sheets, the existing clamping sheet cutting, bending and shaping is produced by additional equipment, and then the cut and shaped clamping sheet is manually placed into the groove on the side wall of the stator core, and then the clamping sheet is pressed and fixed by the clamping sheet machine. Multiple devices occupy a large area, and the material needs to be moved between multiple devices by hand, resulting in low production efficiency. SUMMARY
