Drilling machine with switchable drill bit

Abstract

The invention discloses a drilling machine. According to the drilling machine, a driving motor is arranged in a main shaft box, an inner rod and an outer rod are arranged on a driving telescopic shaft on the driving motor, a fixed block is arranged on the outer rod, a cavity is formed in an operation box below the main shaft box, a first fixed through groove which is used for the outer rod to pass through is formed in a rotary disk in the cavity, a first chute is formed in the first groove wall of the first fixed through groove, two rotary clamping blocks which are hinged to a first sliding block are arranged on the first sliding block in the first chute, the first chute and a second chute in the first groove wall are mutually perpendicular and mutually penetrate through, the second chute is in an inverted trapezoidal shape and comprises an inclined surface, the inclined surface is abutted with the rotary clamping blocks after rotation, a clamping rod which is arranged outside a drill chuck is fixed into two half clamping grooves, a second fixed groove is used for the fixed block to embed, and the drill chuck passes through the second fixed through groove in the operation box. A traditional method for changing a drill by a handheld handle is abandoned, the manual operation process is reduced, and the working efficiency is improved.

Description

technical field [0001] The invention relates to the field of a drill press with switchable drill bits, and more specifically relates to a drill press with switchable drill bits. Background technique [0002] Drilling machines are widely used in modern industry and are common mechanical processing equipment. They are mostly used in drilling and tapping processes. They are divided into two types: ordinary drilling machines and CNC drilling machines. In modern mechanical processing, it is often required to continuously complete two or more processes in the drilling, reaming, countersinking, reaming and tapping of the workpiece to improve the accuracy of the shape, size and position of the workpiece hole. At the same time, the times of loading, unloading and positioning are reduced, and the production efficiency is improved. [0003] Although the single-bit drilling machine of the ordinary drilling machine is easy to operate, it needs to manually replace the drill bit for drill...

AI Technical Summary

Problems solved by technology

[0003] Although the single-bit drilling machine of the ordinary drilling machine is easy to operate, it needs to manually replace the drill bit for drilling. It is inevitable that there will be disadvantages such as difficult positioning, low processing accuracy and low efficiency during operation.
