Apparatus for boring hole in steel tube

Abstract

Disclosed in the invention is an apparatus for boring a hole in a steel tube. The apparatus comprises a hole boring unit and at least one support unit. The support unit consists of a support plate and a hydraulic cylinder; a first chute is formed in the support plate and two first sliding blocks are arranged in the first chute; each first sliding block is provided with one support plate and the two support plates are parallel to each other; the two first sliding blocks are in transmission connection with the hydraulic cylinder by connecting rods with equal lengths. The hole boring unit contains a plurality of drilling heads, wherein the extending directions of the drilling heads are perpendicular to the extending directions of the support plates; and the drilling heads are distributed along the extending directions of the support plates; and horizontal distances between the drilling heads and the two support plates are equal. According to the invention, on the basis of the support unit design, the processing precision can be guaranteed even steel tubes with different diameters and different lengths are processed; and hole boring work can be carried out at different positions of the steel tubes can be carried out. With designs of a first extending plate and a second extending plate, sinking of walls of the steel tubes can be effectively prevented, thereby guaranteeing the processing quality.

Description

technical field [0001] The invention relates to the technical field of metal product processing machinery, in particular to a device for drilling steel pipes. Background technique [0002] Drilling the steel pipe in the radial direction requires passing the drill pipe through the diameter line of the center of the steel pipe; in the axial direction, it is required to be perpendicular to the axis. Moreover, multiple holes need to be drilled on a steel pipe, and the centerlines of all the holes are required to be parallel. Since the axis is a virtual line, it is very difficult to process multiple drilling holes that are circular and perpendicular to the axis. The traditional method is to draw a line and mark the position where the hole will be punched on the steel pipe. Then use the drill to drill the marked points. In fact, this processing method is very rough and the precision is not high. It mainly depends on the experience of the workers. [0003] In Chinese Patent Appl...

Problems solved by technology

This technical solution cannot well locate the position that needs to be drilled, and the machining accuracy is not high. Moreover, when drilling, it is easy to cause a concave area around the upper hole of the metal pipe, thereby affecting the quality of the metal pipe, and it is also not It can drill holes for metal pipes with different diameters, and this technical solution needs further improvement
