High voltage isolating switch arm assembly tooling

Abstract

The utility model relates to a tool for assembling the connecting lever of a high-voltage disconnecting switch, and the tool comprises a pedestal. The pedestal is provided with a support positioning plate which is used for the positioning of a conductive pipe support and arranged along the left-right direction. The support positioning plate is provided with an upper supporting surface and a side supporting surface, which are used for the top pressure cooperation of corresponding side surfaces of the conductive pipe support. The side supporting surface is provided with a threaded hole and a pin hole, which are respectively used for the passing of axial and radial positioning pieces of the conductive pipe support. The pedestal is provided with a connecting lever positioning plate which is used for the positioning of the installation angle of the connecting lever. The connecting lever positioning plate is provided with a connecting lever positioning hole which cooperates with the installation hole of the connecting lever and is used for the passing of a connecting lever positioning piece. The pedestal is also provided with a positioning block which is provided with a positioning surface, wherein the positioning surface cooperates with the peripheral surface of a transmission shaft in a contact manner. End positioning plates, which are used for the axial limiting of the transmission shaft, are disposed in the left-right direction of two sides of the pedestal. The end positioning plates are provided with axial positioning holes for the passing of positioning pieces, wherein the positioning piece is used for the limiting of the ends of the transmission shaft. The tool guarantees the assembly precision of the connecting lever, and also improves the assembly efficiency of the connecting lever.

Description

technical field [0001] The present invention relates to the technical field of high-voltage power transmission and transformation equipment testing, and in particular to a high-voltage isolating switch arm 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 distribution tooling 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. like Figure 1-4 As shown, the transmission mechanism mainly includes the transmission shaft 4, the active crank arm 1, the passive crank arm 2, and the conductive tube support 5 installed at both ends of the transmission shaft 4. During the assembly process of the crank arm, the following requirements are required: the conductive...

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, and there is no available Tooling
