Multifunctional composite cutter

Abstract

The invention relates to the field of cutters for metal cutting machining, in particular to a multifunctional composite cutter. The multifunctional composite cutter comprises a knife handle (1), and the multifunctional composite cutter is characterized in that the cutter further comprises a cutting disc (2), tight locking sleeves (3), a drill bit (4) and a fastening nut (5), wherein the rear end face of the cutting disc (2) is fixed on the front end face of the knife handle (1), at least three cutting seats (21) are arranged at the outer edge of the front end face of the cutting disc (2), andeach cutting seat is fixedly provided with a cutting blade (22); the tight locking sleeves (3) are vertically fixed in the middle of the front end face of the cutting disc (2), and the tight locking sleeves (3) are distributed evenly around the central axis of the cutting disc (2), and the outer side faces of the front parts of the tight locking sleeves (3) are tapped with external threads; and the rear part of the drill bit (4) is inserted among the tight locking sleeves (3), and screw the fastening nut (5) to the outer threads of the tight locking sleeves (3). According to the cutter, the structure is small, use is convenient, combination degree is high, and application range is wide.

Description

technical field [0001] The invention relates to the field of cutters for metal cutting, in particular to a multifunctional composite cutter. Background technique [0002] Boring and reaming are commonly used drilling methods. At present, boring machines and lathes are generally used in combination with their respective tools. In this way, workpieces need to be operated on different machine tools in sequence, and workpieces and tools are clamped multiple times, which not only reduces the operating cost. efficiency, but also affect the machining accuracy. Contents of the invention [0003] In order to overcome the defects of the prior art and provide a cutting tool with simple structure, convenient use, high combination degree and wide application range, the invention discloses a multifunctional compound tool. [0004] The present invention achieves the goal of the invention through the following technical solutions: [0005] A multi-functional compound tool, including a t...
