Description

Technical Field

[0001] The utility model relates to the technical field of metal pipe processing, in particular to a station-type drilling tool for metal pipes. Background Art

[0002] During the construction process, pipe fittings are commonly used materials. When using pipe fittings, they often need to be punched to facilitate subsequent operations such as assembly and installation. When radially drilling holes in round tubes, the drilling position of the round tubes needs to be placed directly below the drill bit of the drilling rig. When radially drilling holes in existing round tubes, tooling workers need to repeatedly align them, which is not only time-consuming but also prone to misalignment of the holes, resulting in damage and waste of pipes.

[0003] The patent with publication number CN214602028U discloses a pipe punching tool, which belongs to the technical field of pipe processing tooling. The key points of its technical solution are that it includes a base and a positioning block arranged on the base, and the upper part of the positioning block is provided with a V-shaped groove that penetrates the positioning block along its length direction; the upper part of the positioning block is provided with an alignment block; the upper surface of the alignment block is provided with a positioning hole that vertically penetrates the alignment block; the axis of the positioning hole is vertically aligned with the bottom of the V-shaped groove; a positioning plate perpendicular to the length direction of the positioning block is provided at one end of the positioning block, and the positioning plate is slidably connected to the base along the length direction of the positioning block; when radially drilling holes in round tubes, the utility model can assist staff in drilling positioning of the round tubes, and the operation is convenient, fast and efficient.

[0004] In the specific use of the above-mentioned prior art, the circular tube is axially positioned by the positioning plate, so that multiple holes can be located on the same circumference when the circular tube is radially punched. However, the adjustable range of the positioning plate relative to the positioning block is too small, and it is only suitable for circular tubes with holes near the end positions. When radial drilling is required in the middle of the circular tube or away from the end, the positioning plate cannot play the role of axial positioning of the circular tube, unless the base is very long. In that case, the punching tool will be very large and not conducive to use. In view of this, we propose a station-type drilling tool for metal pipes. Utility Model Content
