A tooling fixture for a drill cutter head

Abstract

The invention discloses a tooling fixture for a drill cutter head. The drill cutter head includes a cutter head body (1) and a plurality of stepped holes (2) opened on the cutter head body (1). The shoulder between the shank of the knife (3) and the drill bit of the drill (3) is supported on the stepped surface of the stepped hole (2), and a positioning hole ( 4), the tooling fixture includes a base (5), two guide rails (6) fixed on the top surface of the base (5), and two limit posts (7) are set between the two guide rails (6), limiting A cooling mechanism is arranged on the rear side of the position post (7), and the air outlet hole (16) of the cooling mechanism is arranged toward the groove surrounded by the base (5) and the two guide rails (6). The invention has the beneficial effects of preventing the drill cutter head from sliding, prolonging the service life of the drill cutter, enabling multiple drill cutter heads to be tooled, and reducing the temperature of the surrounding working environment.

Description

technical field [0001] The invention relates to the technical field of tooling for drill cutters, in particular to a tooling fixture for drill cutters. Background technique [0002] The drill cutter head is used to install different types of drills, and the drills are supplied to the CNC machining center. The drill cutter head is installed through the tooling fixture, which is set at the tool holder installation position of the CNC machining center. The tooling fixture includes two guide rails fixed at the tool holder installation position. The inner surfaces of the two guide rails are There are guide grooves along its axial direction. When installing the drill cutter, the worker first installs a drill in each mounting hole of the drill cutter, and then slides the edges on both sides of the drill cutter respectively. Into the two guide grooves, so as to realize the tooling of the drill cutter head. The clamping head of the CNC machining center clamps the drill on the drill...

AI Technical Summary

Problems solved by technology

However, although the drill disc can provide the drill for the CNC machining center, there are still the following defects: 1. The drill disc is not fixed at all between the two guide rails, causing the clamping head to clamp the When the drill is used, the drill disc also slides, which causes the position of the next drill to be grabbed by the clamping head to change, but the grabbing program remains unchanged, which leads to collision between the clamping head and the drill. bad, which shortens the service life of the drill bit

2. After the clamping head puts the used drill back on the drill disc, due to the high heat on the drill, it will not only be deformed by heat and reduce its service life, but also transfer heat to the working environment , increasing the ambient temperature, thereby affecting the normal work of workers
