Stator coil straight line side measuring and line drawing device and method

Abstract

The invention provides a stator coil straight line side measuring and line drawing device and method. The device comprises a supporting rod and a reference block, wherein the reference block is provided with an angle R; the extending face of the angle R is provided with a through hole and a check block; the supporting rod penetrates through the through hole of the reference block; the reference block is provided with a fastening screw; and the fastening screw penetrates into the through hole from one face of the reference block. The angle R of the reference block is determined according to the size required by a stator coil, and the reference block can freely slide on the supporting rod to adjust the length of the straight line edge, so that the straight line edge of each product can be drawn and measured by using the device, and the accuracy is high.

Description

technical field [0001] The invention relates to the field of mechanical engineering, in particular to a device and method for measuring and drawing a straight edge of a stator coil. Background technique [0002] In the current production process of the traction motor coil, the coil needs to draw and measure the straight edge to accurately paste the notch insulation. The notch insulation plays the role of isolating the potential difference between the armature conductor and the iron core in terms of design. The process On the one hand, it plays a role in preventing the coil-to-ground insulation from being cut by the iron core during the embedding process. Using this patent can measure the distance between the slots and accurately paste the slot insulation to meet the assembly and use needs of the subsequent process.

AI Technical Summary

Problems solved by technology

In the above technical solution, when the tangent point is determined at the corner R angle between the straight line side and the end of the coil, it is very easy to produce deviations, resulting in errors in the position of the line drawn on the straight line side, which adversely affects the subsequent process flow, and the device is fixed and universal. Not ideal, (3) For different products, the cycle from design device to manufacture is long, the production cost of devices of various sizes is high, and the cost of device storage space is wasted
