Rapid centre hole drilling tooling

Abstract

The invention relates to a rapid centre hole drilling tooling, which comprises a base, an upper V-shaped block, an intermediate V-shaped block, a lower V-shaped block, a clamping pressure plate and a height locating shaft; the base is L-shaped and composed of a transverse plate and a vertical plate; a sliding groove is arranged on the vertical plate; a locating key is respectively arranged on the upper V-shaped block, the intermediate V-shaped block and the lower V-shaped block; the locating key and the sliding groove are in sliding fit; the upper V-shaped block, the intermediate V-shaped block and the lower V-shaped block are fixedly connected with the vertical plate through a bolt; a pressure plate locating shaft is arranged on the intermediate V-shaped block; the clamping pressure plate is rotatably connected with the intermediate V-shaped block through the pressure plate locating shaft; the height locating shaft is fixed on the vertical plate through a locking bolt; and a semicircle is arranged at one side of the clamping pressure plate corresponding to the intermediate V-shaped block. After adopting the structure, a work-piece can be rapidly clamped by matching the clamping pressure plate with the V-shaped blocks; and the work-piece is put on and down conveniently and rapidly; and thus, the drilling quality is high.

Description

technical field [0001] The invention relates to a tool, in particular to a quick drilling center tool. Background technique [0002] In the past, the center hole was drilled on a lathe, which required laborious clamping and positioning, low efficiency, and the center drill was easily broken, which was not suitable for mass production. Contents of the invention [0003] The object of the present invention is to provide a fast center tooling which is convenient and quick to get on and off workpieces and has high drilling quality. [0004] The technical scheme that realizes the object of the present invention is as follows: [0005] Quick drilling center hole tooling, including base, upper V-shaped block, middle V-shaped block, lower V-shaped block, clamping plate and height positioning shaft, the base is L-shaped, and the base is composed of horizontal plate and vertical plate, A chute is set on the vertical plate, positioning keys are arranged on the upper V-shaped block,...
