A processing device for an insulating end ring

Abstract

The invention discloses a machining device of an insulating end ring. A round milling cutter is installed at the position of a drill bit of a radial drilling machine; a rotating workbench can be rotationally fixed to a workbench of the radial drilling machine; each clamping piece comprises a bottom plate, two vertical clamping plates fixed to the upper end face of the bottom plate, and a clamping bolt connected to the vertical clamping plates; the three or more clamping pieces are evenly and detachably fixed to the rotating workbench along the same circumference; three or more cushion blocks are connected to the bottom plates of the clamping pieces in a clamped manner; one end of the upper end face of the cushion block located at the position of a fracture of a phenolic aldehyde fiber container is high, the other end of the upper end face of the cushion block located at the position of the fracture of the phenolic aldehyde fiber container is low, and the height difference is the height difference of the two ends at the position of the fracture of the phenolic aldehyde fiber; and the heights of the rest of the cushion blocks are sequentially decreased from the position close to the high end of the cushion block at the position of the fracture to the lower end of the cushion block at the position of the fracture, and a curve formed after the upper end faces of the cushion blocks are smoothly connected is the same as end ports, different in height, of the machined insulating end ring in shape. The insulating end ring machined through the machining device is high in accuracy, easy to operate, capable of saving manpower, safe, high in work efficiency and high in universality.

Description

technical field [0001] The invention belongs to the field of transformer manufacturing and relates to a processing device for insulating end rings. Background technique [0002] The insulating end ring is made of phenolic paper tube. Some insulating end rings, such as the insulating end ring used in autotransformers, have a vertical fracture on the wall. The height of one end is the same, and the height of the two ends of the other end is different. It spirals downward from the high end to the low end. Its conventional manufacturing process, firstly, the vertical opening of the phenolic paper tube capable of making two insulating end rings is formed into a vertical fracture, and then marks are made on the wall at the upper and lower middle positions of the phenolic paper tube according to the port shapes of the different heights of the insulating end rings, and then Then use a jigsaw to cut two insulating end rings along this mark. This method has low manufacturing precisi...

AI Technical Summary

Problems solved by technology

This method has low manufacturing precision, and cannot guarantee that the outer dimensions of the end ring meet the tolerance requirements of the drawings, and also increases the tediousness and labor intensity in the processing process.
