Description

Aircraft on-board tap tapping equipment convenient for chip discharge Technical Field The invention relates to the technical field of tapping equipment, in particular to aircraft on-board faucet tapping equipment convenient for chip discharge. Background The tapping device of the aircraft-mounted faucet is a precision machining device for machining internal threads in special faucet parts used in areas such as aircraft toilets, kitchens and the like. The aircraft on-board faucet is used as an important component of an aircraft cabin service system, has obvious difference between the structural design and a common civil faucet, is generally manufactured by adopting a light high-strength aluminum alloy or special stainless steel material, and has the characteristics of thinner wall thickness, complex inner cavity structure, high sealing performance requirement and the like. In the manufacturing process of the faucet, the processing quality of the internal thread is directly related to the connection reliability, sealing performance and durability of the faucet with the water supply pipeline for long term use. As disclosed in the application number CN201510673272.2, since the chuck and the workpiece are located on opposite sides of the reference table, when a connecting rod for supporting the chuck is provided between the reference table and the chuck, the connecting rod and the workpiece are also located on opposite sides of the reference table. Therefore, the interference of the connecting rod on the workpiece can be reduced, the tapping machine is convenient for machining the workpiece with the thread position far away from the edge of the workpiece and the cross section area larger, and the volume of the tapping machine can be smaller, however, in the existing tap tapping equipment and machining process, the defects of poor pipe diameter adaptability, difficult chip discharge, insufficient machining stability and the like are also commonly existed. Firstly, traditional tapping equipment generally adopts the tapping head structure of fixed size, when the tap of different pipe diameters needs processing, must change tapping cutter or adjustment equipment parameter of corresponding specification, and complex operation just is difficult to guarantee quick change and produces, has seriously restricted many varieties small batch production's efficiency. Second, during tapping, chip discharge problems are particularly pronounced. The machine carries tap and is usually deep hole structure, and the metal piece that the tapping produced is piled up in hole bottom and screw thread slot easily, if can not in time effectively discharge, the piece can fish tail the processed surface, blocks the tapping cutter even and leads to the screw thread damage or cutter fracture, causes the work piece to scrap. The existing equipment is mostly dependent on cutting fluid flushing or manual cleaning, the chip removal effect is unstable, and the existing equipment is difficult to be suitable for aviation part processing scenes with extremely high requirements on cleanliness. Moreover, the traditional tapping equipment lacks effective sealing and auxiliary support to tap bore edge when processing, leads to the easy skew that produces of work piece in the tapping process, influences straightness accuracy and axiality precision of screw thread, also makes the gas or the liquid of the supplementary chip removal of high pressure leak easily simultaneously, weakens the chip removal effect. In addition, the chips remained in the workpiece after tapping are difficult to clean, and the cleaning procedure is often required to be additionally added, so that the processing period is prolonged. In summary, the existing tapping equipment has obvious technical short plates in the aspects of pipe diameter self-adaption, chip real-time discharge and processing stability, and is difficult to meet the requirements of aviation part manufacturing on efficient, precise and clean processing.
