Flange assembling device for hollow composite insulator

Abstract

The invention relates to a flange assembling device for a hollow composite insulator. The flange assembling device comprises an assembling base; an insulator positioning assembly arranged on the assembling base, wherein the insulator positioning assembly comprises an insulator positioning upper die and an insulator positioning lower die, a first positioning cavity is formed in the lower end of theinsulator positioning upper die, a second positioning cavity is formed in the upper end of the insulator positioning lower die, and the first cavity and the second cavity are jointly matched to forma positioning cavity for installing an insulator; and a flange positioning assembly which comprises a pair of flange positioning plates which are respectively positioned at two sides of the insulatorpositioning assembly. The device has the advantages that the assembling base, the insulator positioning assembly and the flange positioning assembly are matched, so the flanges at the two ends of an insulator can be assembled only through one assembling oil cylinder; the structure is simple, the whole assembling process is very convenient, and the device is suitable for assembling flanges of insulators of different sizes.

Description

technical field [0001] The invention relates to the field of insulator processing, in particular to a flange assembly device for hollow composite insulators. Background technique [0002] At present, when the hollow composite insulator is prepared, the metal accessories at the end and the insulating pipe are assembled, and the method of pouring epoxy resin is mostly used. The characteristic of this method is that there is a large gap between the flange and the pipe to facilitate the filling of the ring. Oxygen resin glue, this gap has a great influence on the shape and position tolerance of the assembled product. The product after filling the epoxy resin needs to be placed in a special oven to cure. In addition, as hollow composite insulators are becoming more and more popular in the power industry The disadvantages of using the above method to prepare insulators in mass production are more and more obvious. Before the product is poured, special tooling is required to assemb...

Problems solved by technology

[0004] Although the above-mentioned assembly device also realizes the assembly of the insulator end flange, it has certain limitations in the process of use, that is, the above-mentioned assembly device, due to its assembly and needs to use It is realized by the cooperation of hydraulic presses, slide rails, etc. Therefore, considering the stroke of the hydraulic press and the processing requirements of insulators of different lengths, most of them are suitable for the assembly of insulators with relatively long lengths. At present, in factory processing, A certain amount of insulators with relatively short lengths will also be produced. When assembling these insulators, they cannot be mixed and used directly. It may be necessary to customize another assembly device with a short stroke, and the cost is relatively high. At the same time, the insulator is positioned according to the size, and then the flange is clamped and positioned by the clamp, and then the hydraulic presses on both sides work at the same time to realize the assembly of the flange. The entire assembly process is also relatively troublesome, and it is not suitable for short-length insulators.
