Novel drill machine work head structure

Abstract

The invention discloses a new working head structure of a drilling machine, which is composed of a connecting shaft, a rotating shaft box, a bearing seat, a rotating shaft, a turnbuckle bolt and a drill device. The connecting shaft is fixedly connected to the rotating shaft box, and the two sides of the rotating shaft box are respectively The bearing seat is symmetrically arranged, and the rotating shaft is fixedly connected to the bearing seat. The drill device is movably connected to the rotating shaft through the flower basket bolt. The upper part of the drill device is connected with the flower basket bolt. The lower part is fixedly connected with a drill bit. In the present invention, a plurality of connecting drill bit devices and an easy-to-disassemble structure are arranged on the rotating shaft to quickly replace the drill bit and improve labor efficiency, and the structure is simple, easy to realize, convenient and efficient.

Description

technical field

[0001] The invention relates to a drilling machine structure, in particular to a novel drilling machine working head structure. Background technique

[0002] Drilling machine refers to a machine tool that mainly uses a drill bit to process holes in a workpiece. Generally, the rotation of the drill bit is the main movement, and the axial movement of the drill bit is the feed movement. The drilling machine has a simple structure and relatively low machining accuracy. It can drill through holes and blind holes, replace special tools, expand, countersink, ream or tap. During the machining process, the workpiece does not move, let the tool move, align the center of the tool with the center of the hole, and make the tool rotate (main movement). The characteristic of the drilling machine is that the workpiece is fixed and the tool rotates. The drill bits in the prior art are separately fixedly connected to the drill press. If holes of different sizes are drilled ...
