A multi-bit steel pipe drilling device

Abstract

The invention relates to the technical field of hole drilling devices, in particular to a multi-drill bit steel tube hole drilling device which comprises a bottom plate, wherein a shaft sleeve for limiting a moveable rod is screwed with the outer side of a rotating shaft; an extrusion block is connected with one side opposite to the moveable base, of a fixing base; rubber teeth are arranged on theouter side of the extrusion block; a groove opening matched with the moveable base is formed in one side far away from the fixing base, of a fixing plate; an arc-shaped groove is formed in one side of the upper end of the fixing plate; the arc-shaped groove is positioned right below a drill bit; dreg falling holes are formed in equal distances at the bottom of the arc-shaped groove; a through hole is formed in the lower part of the outer side of the moveable base; a rocker rod is threaded inside the through hole. Compared with the prior art, the device has relatively good advantages, no artificial assistance is needed, the working efficiency is improved, the labor of operators is saved, multiple hole drilling functions of equipment are met at the same time, holes can be drilled relativelystably, a low defective rate is achieved, raw materials are saved, and the device is worthy of popularization and use.

Description

technical field [0001] The invention relates to the technical field of drilling devices, in particular to a multi-drill steel pipe drilling device. Background technique [0002] At present, the machinery in metal processing is very mature, but many of the equipment are not perfect enough and require manual assistance, but the efficiency of manual assistance is relatively low, and the labor force of the workers is increased, and the multiple drilling functions of the equipment cannot be satisfied at the same time. It is not stable enough when drilling, resulting in a relatively high rate of defective products and wasting raw materials. Therefore, we propose a multi-bit steel pipe drilling device. Contents of the invention [0003] The purpose of the present invention is to solve the shortcoming existing in the prior art, and propose a kind of multi-drill steel pipe drilling device. [0004] In order to achieve the above object, the present invention adopts the following te...
