A drilling tool for bending conductive pipe

Abstract

The invention provides a drilling tool for bending conductive tubes, which includes a positioning base provided with a conductive tube positioning structure for positioning the conductive tubes; and also includes a drilling module set, which includes a first drilling module set and a second drilling module Each drilling module group is composed of a plurality of drilling modules; the second drilling module group has two groups and is arranged symmetrically with respect to the arrangement axis of the first drilling module group when it is fixed on the positioning base; two groups of replaceable drilling modules are installed on the drilling module Drill sleeves, including a large hole drill sleeve for drilling one side of the conductive pipe and a small hole drill sleeve for drilling the other side of the conductive pipe; The avoidance space of the drill bit is avoided when drilling on the side that fits with the positioning base; the bending conductive tube drilling tool is used for one-time positioning of the bending conductive tube, and the non-equal-diameter through holes are realized by replacing different drill bushings. Processing ensures that the processed holes have high precision.

Description

technical field [0001] The invention relates to a drilling tool for bending conductive pipes. Background technique [0002] The bending conductive tube used on the model GW46-550 scissor type isolating switch is as follows: figure 1 and figure 2 As shown, the length of the bent conductive tube is relatively long, including the straight section 1 and the inclined section 2. Usually, the bent conductive tube is two bent conductive tubes with an axisymmetric structure, and they are used in pairs. The axisymmetric bent conductive pipe of the conductive pipe also includes a straight section 3 and an oblique extension section 4, and, as image 3 As shown, the cross section of the bent conductive pipe and the bent conductive pipe which is symmetrical with it are both ring-shaped, including two horizontal sections 5 arranged in parallel and spaced apart, and a curved section 6 connected at the ends of the two parallel horizontal sections. The conductive pipe needs to be processe...
