AI Technical Summary

Technical Problem

In the existing technology, the gap between the generator ring lead assembly hole and the ring lead is not accurately measured, resulting in unreliable fixing, easy loosening and wear, causing electrical grounding shutdown accidents and economic losses.

Method used

A clamping device employing a tensioning structure and a threaded lifting structure, through the cooperation of an arc-shaped pressure block and a threaded seat, achieves clamping of the annular lead wire and measures the assembly clearance. This includes the combined use of a pressure plate, tensioning screw, tensioning nut, arc-shaped pressure block, threaded seat, and lifting bolt, simulating the actual installation state for measurement.

Benefits of technology

It achieves precise measurement of assembly gaps, ensuring that the generator ring lead is securely fixed, preventing loosening and wear, avoiding electrical grounding shutdown accidents, and features a simple structure and convenient operation.

Abstract

The application discloses a generator ring lead assembly gap measuring and pressing device and method, and relates to the technical field of generator design and manufacturing. The device comprises a pressing plate, a tensioning screw, a tensioning nut, an arc-shaped pressing block, a threaded seat and a jacking bolt. The arc-shaped pressing block, the threaded seat and the jacking bolt are arranged on the pressing plate. The jacking bolt drives the arc-shaped pressing block to move downwards to press the ring lead under the product pre-tightening force. The distance between the top surface of the arc-shaped pressing block and the top surface of the pressing block assembly groove is measured to measure the generator ring lead assembly gap, so that the felt can be accurately configured, the end structure of the generator is stably fixed during operation, and the loosening of the generator is prevented to cause electrical grounding shutdown accidents and huge economic losses. The device has simple and ingenious structure, simple and convenient process operation, strong controllability, can simulate the assembly state of the actual product, and realizes accurate measurement.
