Drilling machine with multiple drill bits

Abstract

The invention discloses a drilling machine with multiple drill bits, comprising: a workbench, a sliding rod, a drilling mechanism and a clamping part; the sliding rod is vertically fixed on the upper surface of the workbench, the drilling mechanism is arranged on the sliding rod, and the working At least two matching clamping parts are arranged on the upper surface of the table; the drilling mechanism includes: a drilling box, a drill bit fixing part and a drill bit; the drilling box is slidably arranged on the sliding rod, and the drill bit fixing part and the drilling The output shaft of the motor in the box is connected, and the lower surface part of the drill bit fixing part is recessed inward to form a plurality of drill bit grooves, the bottom of each drill bit groove is provided with a telescopic column, and the lower end of each telescopic column is connected with a drill bit, and the drill bit can be retracted. into or out of the drill slot. The drilling machine with multiple drill bits overcomes the problem that the drilling machine in the prior art needs to replace different drill bits to drill different apertures, and the process of replacing the drill bits is cumbersome, which seriously affects the work efficiency.

Description

technical field [0001] The invention relates to a drilling device, in particular to a drilling machine with multiple drill bits. Background technique [0002] Drilling machine refers to the general name of machinery and equipment that uses tools harder and sharper than the target object to leave cylindrical holes or holes on the target object by means of rotary cutting or rotary extrusion. It plays a very important role in industrial production. Important role, for example, in the field of mold processing, the drilling operation of the mold. [0003] However, the drilling machine in the prior art needs to replace different drill bits to drill different apertures, and the process of changing the drill bits is loaded down with trivial details, which seriously affects the work efficiency. [0004] Therefore, it is an urgent problem to be solved in the present invention to provide a drill with multiple different diameters, which can be quickly replaced as required, so as to dri...

Problems solved by technology

[0005] In view of the above technical problems, the purpose of the present invention is to overcome the problem that the drilling machine in the prior art needs to replace different drill bits to drill different hole diameters, and the process of replacing the drill bits is cumbersome, which seriously affects the work efficiency. There are multiple drill bits of different diameters, and the drill bits can be quickly replaced according to the needs, so as to drill different hole sizes with a multi-drill drill
