Drilling machine with drill bit convenient to replace

Abstract

The invention discloses a drilling machine with a drill bit convenient to replace. The drilling machine comprises a sleeve drill stand column, wherein a drilling machine shell is fixed to the upper end of the sleeve drill stand column, fixing pipes are arranged in the drilling machine shell, and the drill bit rod is connected to the interiors of the fixing pipes through bearings. According to thedrilling machine, when the drill bit needs to be replaced, firstly, a rotating handle is rotated clockwise to drive a rotating rod to rotate, the rotating rod drives first rotating discs arranged at the left end and the right end of the rotating rod to rotate, and the first rotating discs rotate to drive second rotating discs on spiral sleeves to rotate under the action of belts, so that under thematching action of the bearings, the spiral sleeves are driven to rotate; and due to the fact that the thread direction of the spiral sleeve and the thread direction of a screw at the left side of the fixing steel pipe are opposite to the thread direction of the spiral sleeve and the thread direction of a screw at the right side of the fixing steel pipe, the screws at the two sides of the fixingsteel pipes can move reversely under rotation of the spiral sleeves, and locking of the drill bit is relieved; and when the drill bit is installed, only the rotating handle needs to be rotated in anti-clockwise direction, so that the purpose of simply, conveniently and quickly replacing the drill bit is achieved.

Description

technical field [0001] The invention relates to the technical field of drilling machines, in particular to a drilling machine for conveniently replacing drill bits. Background technique [0002] With the vigorous development of machinery manufacturing industries such as home appliances and automobiles, many industries need to fix perforated part plates. Drilling machines are born in response to demand. However, when making part plates with different hole diameters and sizes, different sizes and specifications are required. When replacing the drill bit, the traditional drilling machine generally needs to use external tools to loosen the bolt and then remove the bolt to realize the replacement of the drill bit. The operation steps are complicated, which makes it troublesome and inconvenient to replace the drill bit. Lost, causing inconvenient use, leading to the problem of prolonging the production cycle, so there is an urgent need for a drilling machine that can replace the d...
