Description

Technical Field

[0001] The utility model relates to the technical field of tube processing equipment, and more specifically, particularly relates to an adjustable diameter boring tool for aluminum tubes used in GIS. Background Art

[0002] As the competition in the switch market at home and abroad becomes increasingly fierce, high-voltage switch products are gradually developing in the direction of miniaturization, low cost, and high reliability. Users emphasize quality and appearance in product procurement. At present, the types of pipes for gas-insulated metal-enclosed switchgear (GIS) on the market are different, and the diameters range from φ300 to φ1000. Previously, ordinary boring flat discs were used for processing. When processing each diameter, the position of the flat disc needed to be adjusted, and the arc was bored by a single boring tool. The adaptability range was small, and due to the size limitation of the boring machine flat disc, the maximum boring arc diameter was φ800, and the processing of pipes above φ800 could not be completed, and the entire flat disc needed to be replaced. At the same time, the debris generated during the boring process needed to be stopped regularly for cleaning, resulting in low processing efficiency. Utility Model Content

[0004] In order to achieve the above-mentioned purpose, the technical solution adopted by the utility model is as follows: an adjustable diameter boring tool for aluminum tubes for GIS, comprising a rotating seat connected to a driving device, and also comprising a cutter disc and at least one cutter disc seat and a boring tool. A boring spindle is fixedly provided in the middle of one side of the rotating seat. The boring spindle is a hollow structure. A blowing device is provided inside the boring spindle. A cutter disc is fixedly provided at the outer end of the boring spindle. An air hole connected to the inside of the boring spindle is opened in the middle of the cutter disc. The cutter disc seat is fixedly installed on the outside of the cutter disc, and the boring tool is detachably connected to the cutter disc.

[0005] Preferably, a T-shaped slot is provided on the surface of the cutter pressing disc along the length direction, the boring tool is movably inserted in the T-shaped slot, and the boring tool is fixedly connected to the cutter pressing disc by screws.

[0006] Preferably, a plurality of threaded holes are evenly formed on both side edges of the cutter pressing disc along the length direction.

[0007] Preferably, the blowing device comprises a battery, a mesh plate and a fan, the mesh plate and the battery are fixedly installed inside the boring spindle, and the fan is fixedly installed on one side of the mesh plate, with the air outlet of the fan facing the air hole.

[0008] Preferably, an opening is provided on the surface of the boring spindle, a cover plate is installed in the opening, and an air inlet is provided on the surface of the cover plate.

The boring tool is fixed to the T-slot of the tool press seat by screws, and then the rotating seat is driven by the driving device to rotate and feed to complete the boring arc operation of the cylinder (pipe). The debris generated during the boring arc processing can be blown away by the fan, so there is no need to stop the machine for cleaning, thereby improving the processing efficiency.

[0012] This tooling only needs to adjust the length of the boring cutter extending out of the cutter plate each time the cylinder diameter is processed, and has a wide range of applications. BRIEF DESCRIPTION OF THE DRAWINGS
