Abstract

The invention discloses a square wire box tapper, and belongs to the technical field of tools. A first bearing is connected with an output shaft, the other end of the output shaft is connected with a first gear through a first flat key, the other end of the output shaft is connected with a circlip for a shaft, a second bearing and a coupler, and the output shaft is connected with a gearbox. One end of a gear shaft is connected with a second gear and a third bearing, and the other end of the gear shaft is connected with a fourth bearing. The square wire box tapper has the advantages that a square wire box hole can be formed, motor drive is adopted, a crawler-type tool is driven to work after gear reduction, multi-stage gear reduction is carried out, transmission efficiency can be improved, and the crawler-type tool effectively solves the problem that the cutting range cannot exceed the center of the tool; the tool has an A*A (square) specification, an A*B (rectangular) specification and other multiple specifications, a cutting edge part of the tool can be a hard alloy and tool apron welded or particle alloy cutting sheet, cutting edges can be arranged in a right-row matrix mode or an inclined-row staggered mode, a coupler quick mounting structure is adopted for the tool and machine parts, and a multi-sheet overlaid telescopic structure is adopted for a movable cover.
