Abstract
The invention relates to the technical field of machining tools, and discloses a reaming-counterboring integrated cutter. The reaming-counterboring integrated cutter comprises a reaming section, a counterboring section and a mounting section, the reaming section comprises a reamer guide column and three reamers which are spirally arranged on the reamer guide column, and the three reamers are arranged at equal intervals in the circumferential direction of the reamer guide column; the counterboring section comprises three countersinks connected with the reamers in a one-to-one correspondence manner, and transition fillets are arranged at the joints of the countersinks and the reamers; and the mounting section is arranged at the end, away from the reaming section, of the counterboring section and is used for mounting the reaming-counterboring integrated cutter. The number of the reamers and the number of the countersinks are both three, so that the reaming-counterboring integrated cutter is beneficial to improving the stability and centering performance of reaming and counterboring; the transition fillets are arranged at the joints of the countersinks and the reamers, so that the the reaming-counterboring integrated cutter is beneficial to improving the surface quality of counterboring; and reaming and counterboring operation on aluminum alloy parts can be achieved on the whole, the hole manufacturing process is simplified, the hole manufacturing efficiency is improved, and meanwhile the labor intensity of operators is relieved.
Description
technical field [0001] The invention relates to the technical field of processing tools, in particular to a hinge-sink integrated cutter. Background technique [0002] Aluminum alloys for aviation are cold-treated forging alloys, which have the characteristics of high strength, high specific strength, corrosion resistance, good mechanical properties and anodic reaction. Widely used in large civil aircraft, such as C919 aluminum alloy accounts for more than 60%. Aluminum alloy materials need to be connected with other structures during the application process. The connection is the weak link of the aluminum alloy material structure. 60-80% of the damage in aerospace vehicles occurs in the connection parts. However, there are a large number of aluminum alloy connecting holes of various types and sizes that need to be processed in modern aircraft, which puts forward extremely high requirements for hole-making accuracy, hole-making quality and hole-making efficiency, so as to e...
