Description

GIS aluminum alloy shell threaded hole aluminum scrap cleaning device

Technical Field

The utility model relates to a piece cleaning device, more specifically say, relate to a GIS aluminum alloy shell screw hole aluminium bits cleaning device.

Background

"Gas Insulated Switchgear" (Gas Insulated Switchgear) is abbreviated as GIS. Primary equipment except a transformer in a transformer substation, including a circuit breaker, a disconnecting switch, a grounding switch, a voltage transformer, a current transformer, a lightning arrester, a bus, a cable terminal, an inlet and outlet bushing and the like, is organically combined into a whole through optimized design. The GIS aluminum alloy shell is one of key parts in a GIS combined electrical apparatus, and mainly has the following functions: 1. a gas container, wherein SF6 gas is injected into the gas container (for insulation and arc extinction); 2. sealing protection is carried out, so that the equipment is prevented from absorbing moisture and water, and external impurities are prevented from entering; 3. the grounding protection ensures the safe operation of the equipment; 4. heat dissipation, which helps the heat generated in the operation process of the equipment to be dissipated to the air through the shell; 5. and the supporting and fixing are used for supporting and fixing the conductive elements and the manipulator components of the internal equipment.

The GIS aluminum alloy shell is generally formed by casting, and the cast aluminum alloy shell needs to be machined. A plurality of aluminum scraps are left in the threaded hole of the aluminum alloy shell, the aluminum scraps are blown clean by a common dust removal gun, but the aluminum scraps in the threaded hole are difficult to blow clean under the mixed state of cutting fluid and the aluminum scraps, and the reason is as follows: ordinary dust removal rifle is blowing the in-process, and the aluminium bits is unordered in the screwed hole motion, and some cards of little aluminium bits are between the screw thread, can not clear up thoroughly. The residual aluminum scraps cannot be seen visually, and when the product is assembled, the screwed bolt is blocked, so that the thread is damaged, and the product is scrapped. In more serious cases, other parts already assembled also need to be removed, causing huge losses.

The Chinese patent number ZL201210339369.6, the granted announcement date is 11 months and 5 days in 2014, and the name of the invention creation is as follows: a threaded hole aluminum skimming clearing and purging device and method, this application relates to a threaded hole aluminum skimming clearing and purging device and method, there are slide rails on the work level, the air needle frame with air needle slides along the slide rail back and forth, the air needle frame connects the air source switch through the flexible compressed air pipeline, there is a closed cavity communicating air needle and compressed air pipeline in the air needle frame; the air needle can extend into the threaded hole of the workpiece and uses compressed air to purge aluminum chips and other dirt. This application is in the same place multiunit gas needle combination to specific product, once sweeps a plurality of screw holes on the product promptly, can be suitable for batchization, automated production, but its gas needle sweep the principle the same with ordinary dust removal rifle, still exists the aluminium bits and sweeps unclean problem, influences product assembly effect.
