Steel tube drilling device provided with multiple drill heads

Abstract

The invention provides a steel tube drilling device provided with multiple drill heads. The device comprises a workbench, a driving mechanism, a drilling mechanism and a clamping mechanism, wherein the driving mechanism comprises a first gear, a rack and a drive shaft; the drilling mechanism comprises multiple drilling apparatuses, and each drilling apparatus comprises a stand column mounted on the workbench, a cross bar mounted on the stand column, a connecting plate mounted on the stand column and at least two drilling units; each drilling unit comprises a slider, a first connecting rod, a second gear and a drill rod; the connecting plates are hinged with the sliders through second connecting rods with equal lengths; the clamping mechanism comprises a mounting plate, a first drive device and clamping devices symmetrically arranged at two ends of the mounting plate; each clamping device comprises a bracket, a first rotating shaft and a clamping unit, the first rotating shaft is horizontally and rotationally mounted on the bracket, and the clamping unit is mounted on the first rotating shaft; the first drive device is in transmission connection with the first rotating shafts through transmission mechanisms. The device can drill multiple holes in the same steel tube, and the product quality is high.

Description

technical field [0001] The invention relates to the technical field of steel pipe processing, in particular to a multi-bit steel pipe drilling device. Background technique [0002] For a long time, there has been a demand for drilling steel pipes in the industry. For example, in the field of electric power construction, steel pipe towers are widely used for power transmission lines, and the ladder pipes in steel pipe towers need to drill many nail connection holes. The traditional drilling method is pole drilling, which has the disadvantages of cumbersome procedures, low dimensional accuracy, low processing efficiency, and prone to distortion, which directly affects the smooth progress of subsequent processes. [0003] Of course, drilling machines can also be used to drill holes in steel pipes. However, traditional drilling machines need to mark the parts of the steel pipes to be drilled in advance, and the accuracy of steel pipe drilling depends largely on the position accu...

The traditional drilling method is pole drilling, which has the disadvantages of cumbersome procedures, low dimensional accuracy, low processing efficiency, and prone to distortion, which directly affects the smooth progress of subsequent processes

[0003] Of course, drilling machines can also be used to drill holes in steel pipes. However, traditional drilling machines need to mark the parts of the steel pipes to be drilled in advance, and the accuracy of steel pipe drilling depends largely on the position accuracy of the parts to be drilled. , and once the drilling is completed, if drilling is required, the drilling operation needs to be stopped, and the position of the steel pipe to be drilled should be marked again, which is time-consuming and laborious
