Parallel line check tool for normal at any point on the surface of revolution where the generatrix is ​​a straight line

Abstract

The invention relates to a checking tool for parallel lines of a normal at any point on a rotation face, wherein the bus of the rotation face is a straight line. Six sharp points on a front baffle, a back baffle and two locating pins in the tool all make contact with the rotation face, the correctness of the normal parallel lines at the sharp points of the locating pins are checked through the external circular face of a large alignment pin and the external circular face of a small alignment pin, and the correctness of the normal parallel lines on other positions on the rotation face is checked by moving the position of the tool many times. By means of the checking tool, the problem that checking of the normal parallel lines at any point on the rotation face is inaccurate is solved, wherein the bus of the rotation face is the straight line.

Description

Technical field: [0001] The invention relates to a parallel line inspection tool for the normal line at any point on a rotary surface whose generatrix is ​​a straight line. Background technique: [0002] The original model of the present invention is the profile part of the fixed side plate on the conical surface of the end tire in the manufacturing mold of the stator coil of the large and medium-sized motor. The stator coil is one of the most important parts in the large and medium-sized motor, and it can be said to be the heart of the motor. The quality of the motor is directly related to the quality of the whole motor. With the continuous production of nuclear power units and other units, the processing and manufacturing accuracy requirements for each part of the motor are becoming more and more stringent, especially the most important coil part of the motor. At present, when manufacturing large and medium-sized motor stator coils in China, most of them use the coil mold ...

Problems solved by technology

At present, when manufacturing large and medium-sized motor stator coils in China, most of them use the coil mold pressing method. The manufacturing accuracy of the coil mold directly determines the accuracy of the coil. The key and difficult point of the coil mold manufacturing is the side on the conical surface of the end tire The molded line part of the panel, the inspection results of the molded line part of the fixed side panel have been inaccurate all the time. When checking here, a single model is used, and the method of two-point positioning is used. The result of this method is in Theoretically, it is an approximate value, and there is still a large human error in the operation. The inspection result changes with the placement of the sample. This method cannot provide reliable quality assurance for the manufacture of the coil mold, and ultimately affects the manufacturing accuracy of the stator coil.
