Trepanning device used for copper bar insulation sleeve and use method thereof

Abstract

The invention provides a trepanning device used for a copper bar insulation sleeve. The device comprises a mounting frame and a trepanning device; the mounting frame comprises two supporting feet anda cross beam for connecting the two supporting feet, the trepanning device comprises a sleeve, a connecting screw rod and trepanning knives, the trepanning knives are vertically placed, knife bits face downwards, the two trepanning knives are arranged and are symmetrically arranged along the connecting screw rod, the lowest points of the knife bits of the two trepanning knives are located on the same horizontal plane, the trepanning knives and the connecting screw rod are connected through connecting strips, the connecting strips are horizontally arranged and move in the length direction, theinteriors of the connecting screw rod is hollow to form a mounting cavity, a laser assembly is arranged in the mounting cavity, when the two trepanning knives rotate, the cutting thicknesses of the insulation sleeve are the same, in the trepanning process, the copper bar stress is uniform, a zinc coating of the copper bar is prevented from being scratched, and use is reliable. The invention further provides a use method of the trepanning device. The rotating type trepanning work is adopted, and in the trepanning process, the damage to the zinc coating of the copper bar is avoided.

Description

Technical field [0001] The invention relates to the technical field of hole openers, in particular to a hole opener used for copper bar insulating sleeves and a method of use. Background technique [0002] Copper bars are conductive materials often used in high-voltage power distribution cabinets. In order to protect equipment and personal safety, it is often necessary to cover the copper bars with a layer of insulating material, because the original connection holes on the copper bars are blocked after the insulating material is applied. , It is necessary to open holes to expose the original connecting holes. At present, the method of cutting directly by the tool is basically used to open the hole, which is more troublesome and easy to hurt your hands. At the same time, the galvanized layer on the copper bar is easily scratched due to the uneven force of the tool. Summary of the invention [0003] The purpose of the present invention is to provide a hole opener for copper bar in...
