Reaming cutter with adjustable blade locking mechanism

Abstract

The utility model belongs to the technical field of chambering cutters, particularly relates to a chambering cutter with an adjustable blade locking mechanism, and aims at solving the problem that an existing blade cannot be replaced, the chambering cutter comprises a cutter bar, a clamping groove is formed in the cutter bar, a clamping block penetrates out of the clamping groove, the blade is fixedly installed at the bottom end of the clamping block, and the adjustable blade locking mechanism is arranged on the cutter bar. A locking mechanism is arranged on the outer wall of the cutter bar; the locking mechanism comprises a sliding block, the torque strength between the cutter bar and the blade is improved through mutual meshing of the clamping groove and the clamping block, and the cutter bar and the blade are fixed through a limiting rod at the top end of the sliding block, penetrate through an abutting block through a through hole and penetrate into a fixing ring through a limiting hole and are fixed under abutting of a fastening ring at the same time. According to the broaching tool, the tool bar and the blade can be rapidly disassembled and locked, the stability after assembly is improved through limiting of the limiting rod, the loosening condition is avoided, the suitable blade can be replaced according to the use condition, and the situation that the whole broaching tool is tedious and troublesome to replace is avoided.
