Embodiment Construction

[0014] like Figure 1-3 As shown, a tooling for installing a spring hoop of the present invention includes an annular support 2, and ten cylinders 4 are evenly fixed on the outer wall of the support 2 along the circumferential direction of the support 2, and the cylinder body of the cylinder 4 is connected to the The air source is connected, and the air connection pipe is provided with an air valve (not shown in the figure) to control the on-off of the air connection pipe. The cylinder 4 includes a piston rod that expands and contracts along the radial direction of the bracket 2 and extends to the inner side of the bracket 2. The piston rod passes through the bracket 2, and the end of the piston rod is located inside the bracket 2 and is fixed to hook the inner ring of the spring hoop 6 to apply radial pressure. Claw piece 1 that pulls outward. The claw member 1 is driven by the piston rod of each cylinder 4 to move outward along the radial direction of the bracket 2 .

Abstract

The invention discloses a spring band installation fixture which comprises an annular bracket, wherein multiple cylinders are evenly arranged on the outer wall of the annular bracket along the circumferential direction of the bracket, each cylinder comprises a piston rod which stretches out and draws back along the radial direction of the bracket and extends to the inner side of the bracket, a claw piece which is used for hooking the inner circle of the spring band and applying radial outward tension is fixed on the tail end of the piston rod of each cylinder, which is arranged at the inner side of the bracket, and the cylinder body of each cylinder is communicated with an air source through an air channel connecting pipe. The claw pieces can be driven to move outwards along the radial direction of the bracket by the piston rods and the spring band is driven to expand outwards by the claw pieces, thus the expansion of the spring band can be easily realized, the operation is simple and the assembly efficiency is high.

Description

technical field [0001] The invention relates to a tooling for installing a spring hoop on a petal-shaped contact finger of a million-volt grade GIS product. Background technique [0002] The petal-shaped contact finger assembly is a part of the high-voltage circuit breaker product used for the conduction of the moving parts. 30 contact fingers are evenly distributed on the outside of the cylinder, and two spring hoops are used on the outside of the contact fingers to make the contact fingers and the cylinder well contact. . The traditional assembly is to use manpower to open the spring hoop and put it on the contact finger, which is very inconvenient due to the large contraction force of the spring hoop. SUMMARY OF THE INVENTION [0003] The purpose of the present invention is to provide a spring hoop installation tool which can easily open the spring hoop, has simple operation and high assembling efficiency. [0004] The present invention adopts the following technical ...
