Description

Technical Field

[0001] The utility model belongs to the technical field of fan-shaped sheet production, in particular to a fan-shaped sheet same-plate difference measuring device. Background Art

[0002] The stator core is an important part of the stator and the main component of the motor magnetic circuit. It is composed of fan-shaped pieces, ventilation slot pieces, positioning ribs, upper and lower tooth pressure plates, tension bolts and support plates. The stator core is punched into fan-shaped pieces with silicon steel sheets and stacked on the positioning ribs.

[0003] However, in the existing technology, the original self-adhesive process has a relatively small thickness of the self-adhesive section; the same board difference has little effect on the quality of the self-adhesive section. When the thickness of the self-adhesive section increases, the same board difference will affect the shape and position tolerance of the higher self-adhesive section and product performance. Therefore, in order to stack the higher self-adhesive section, a new equipment should be designed to avoid the same board difference affecting product quality. Utility Model Content

[0004] The utility model aims to provide a device for measuring the difference between fan-shaped plates and plates, so as to solve the problems raised in the above-mentioned background technology.

[0005] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0007] Furthermore: the thickness of the lower base plate and the upper pressure plate are both 30 mm, which ensures the strength; the height of the equal-height columns is 315 mm, which ensures the number and thickness of the stacked fan-shaped sheets.

[0008] Furthermore: the thickness of the reference plate is 10 mm, which facilitates uniform force application when pressing down.

[0009] Furthermore, the bottom end of the equal-height column is threadedly connected to the lower base plate to facilitate disassembly, assembly and fixation.

[0010] Furthermore, the tightening bolt and the upper pressure plate are threadedly connected to ensure self-locking and tightening fixation.
