Scissor-type high-voltage isolating switch assembly tooling

Abstract

The invention mainly relates to a scissors type high-voltage isolating switch assembling tool which comprises a base. The base is provided with a crank arm positioning board for positioning the assembling angle of a crank arm, and a positioning block which performs a supporting function on a transmission shaft. The side surface of the crank arm positioning board is provided with a crank arm positioning hole which is through in a front-and-back direction and is used for penetration of a positioning member for positioning the crank arm. The positioning block has a positioning surface for contact fit with the circumferential surface of the transmission shaft. The base is provided with a supporting block which performs a supporting function on the input shaft. The supporting block has a supporting surface for contact fit with the circumferential surface of the input shaft. The base is also provided with a position limiting mechanism for limiting radial rotation of a sector gear. The position limiting mechanism comprises a slide block which radially moves along the sector gear. The slide block is provided with a positioning surface which is used for press-fit with the circumferential surface that corresponds with the toothless part of the sector gear and restricts rotation of the sector gear. The invention aims to provide the high-voltage isolating switch assembling tool which can improve assembling efficiency of the high-voltage switch and can ensure high crank arm assembling precision.

Description

technical field [0001] The invention relates to the technical field of high-voltage power transmission and transformation equipment testing, in particular to a scissor-type high-voltage isolating switch assembly tool. Background technique [0002] The high-voltage isolating switch is mainly used to reliably isolate the part that needs to be powered off from the live part in the high-voltage power distribution device to ensure the safety of maintenance work. In order to ensure the normal opening and closing of the product and the reliable locking of the closing switch, the requirements for the transmission mechanism of the product are relatively high. Such as Figure 8-9 As shown, the transmission mechanism mainly includes a transmission shaft 5, a crank arm 3, a pinion 4, a sector gear 6, an input shaft 22 and a flange 11 installed at one end of the input shaft 22, etc. Engaging transmission within the angle range, in the assembly process of the crank arm, the following req...

AI Technical Summary

Problems solved by technology

In the actual assembly process, in order to meet the requirements of the assembly angle of the crank arm, the efficiency of visual inspection or measurement with measuring tools is relatively low. It is also very difficult to achieve such high-precision assembly requirements without the use of tooling. During the process, it is necessary to ensure that the sector gear and the pinion can be normally meshed for transmission. There are also certain requirements for the radial relative position of the sector gear on the input shaft, and there is currently no high-voltage switch assembly tool available.
