Novel multi-shaft drilling mechanism for steel bar connecting structural member

Abstract

The invention discloses a novel multi-shaft drilling mechanism for a steel bar connecting structural member. The novel multi-shaft drilling mechanism comprises a rack; a working table plate is fixed to the upper side of the rack; a supporting frame is installed on the upper side of the working table plate; a distance adjusting mechanism is installed in the supporting frame; drilling assemblies are arranged on the distance adjusting mechanism; the number of the drilling assemblies is two; each drilling assembly comprises a driving motor, a transmission box and two drill bit mechanisms; the two drill bit mechanisms are arranged at the bottom of the corresponding transmission box side by side; each drill bit mechanism comprises a rotating shaft; and a connecting block is fixed to the lower end of each rotating shaft; and a drill bit is arranged at the bottom of each connecting block. The distance between the two drilling assemblies can be accurately adjusted; the drilling effect is improved; the positions, needing to be drilled, of the steel bar connecting structural member can be positioned through first positioning protruding strips on the front sides of containing bases and second positioning protruding strips on the front sides of lower pressing blocks; and the drilling accuracy is further improved.

Description

technical field [0001] The invention relates to the field of building material processing, in particular to a novel multi-axis drilling mechanism for steel bar connection structural parts. Background technique [0002] Rebar is a kind of building material, which is widely used in various building structures, especially various large, heavy, light thin-walled and high-rise building structures. Steel bar refers to the steel used for reinforced concrete and prestressed reinforced concrete. Its cross section is circular, sometimes square with rounded corners, including smooth round steel bar, ribbed steel bar, and twisted steel bar. Rebar connection structural parts generally need to be drilled, which is processed by using a multi-axis drill. Multi-axis drilling is a hole processing equipment used in drilling, tapping, boring, reaming, etc. in the mechanical field. It is a newly emerging machine tool in China that improves production efficiency and reduces costs. [0003] At p...

Problems solved by technology

[0003] At present, most of the upper drilling rigs of existing multi-axis drilling machines are fixed, and the distance between two adjacent drilling rigs is difficult to adjust. Most of the adjustable ones are manually adjusted, and it is difficult to ensure the accuracy of the distance between two adjacent drilling rigs. As a result, there is a deviation between the position of the drilling rig and the position that needs to be drilled on the steel bar connection structure, and because the steel bar connection structure is mostly circular, when the drill bit drills the steel bar connection structure, it is easy to cause the drill hole to be skewed due to the slip of the drill bit , reducing the drilling effect
