High voltage isolating switch arm assembly tooling

Abstract

The invention relates to a connecting lever assembling tool of a high-voltage disconnecting switch. The assembling tool comprises a pedestal; support positioning plates that are distributed along the left-right direction and are used for localizing a conductive tube support are arranged at the pedestal. The support positioning plates have upper support surfaces and side support surfaces; the upper support surfaces are used for realizing pressing cooperation of the downward inner side surface of the conductive tube support and the side support surfaces are used for realizing pressing cooperation of the corresponding sides of the conductive tube support and limiting the conductive tube support axially; the side support surfaces are threaded holes and pin holes, wherein positioning elements for localizing the conductive tube support axially and radically pass through the threaded holes and pin holes respectively. Beside, a connecting lever positioning plate for localizing the connecting lever installation angle is also arranged at the pedestal; a connecting lever positioning hole is formed in the connecting lever positioning plate, wherein the connecting lever positioning hole cooperates with a connecting lever mounting hole and a connecting lever positioning element passes through the connecting lever positioning hole. Positioning blocks for supporting a transmission shaft are arranged at the pedestal and have positioning surfaces that are used for contact and cooperation with transmission shaft circumference surface. Therefore, the assembling precision of the connecting lever can be guaranteed and the connecting lever assembling efficiency can be improved.

Description

technical field [0001] The invention relates to the technical field of high-voltage power transmission and transformation equipment testing, 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 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 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 tub...

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
