Multifunctional milling cutter mechanism of cam cutter

Abstract

The invention discloses a multifunctional milling cutter mechanism of a cam cutter. The multifunctional milling cutter mechanism comprises a clamping groove, a tool holder, a tool bit, a first notchedblade, a first chip space, a first side edge, a first fixing block, a second chip space, a second fixing block, a second side edge, a second notched blade, an end edge, a third chip space, a third side edge and a pilot drill. According to the multifunctional milling cutter mechanism of the cam cutter disclosed by the invention, the first side edge and the second side edge are arranged on the sidefaces of the first fixing block and the second fixing block, respectively, and the first notched blade and the second notched blade are arranged on the side faces of the first side edge and the second side edge, respectively, so that dual milling of an object is realized, the milling quality is improved, and breakage of a milling cutter is further avoided. Meanwhile, the pilot drill is welded atthe end of the tool bit, the end edge of the pilot drill is of a conical structure, and the side edge of the pilot drill is of a spiral structure, so that convenience is brought to location before milling. Therefore, the milling precision is improved, and the milling quality is further improved.

Description

technical field [0001] The invention relates to a multifunctional milling cutter mechanism, in particular to a multifunctional milling cutter mechanism of a cam machine tool, which belongs to the field of mechanical manufacturing. Background technique [0002] A milling cutter is a rotating tool with one or more teeth for milling. When working, each knife tooth cuts off the allowance of the workpiece intermittently in turn. Milling cutters are mainly used for machining planes, steps, grooves, forming surfaces and cutting off workpieces on milling machines. A narrow margin is ground on the flank to form a relief angle. Due to the reasonable cutting angle, its life is relatively high. The tooth back of the sharp-tooth milling cutter has three forms: straight line, curved line and broken line. Straight backs are often used for fine-toothed finishing milling cutters. The teeth with curved and broken line tooth backs have better strength and can withstand heavy cutting loads,...

AI Technical Summary

Problems solved by technology

[0003] The cutting edge of the current milling cutter is generally relatively flat. When encountering a hard object, the cutting edge of the milling cutter cannot finish cutting the object in time, which may easily cause the milling cutter to break. In order to ensure the accuracy of the milling cutter, sometimes a fixed The core drill is used for drilling and positioning, and then the milling cutter is replaced for milling, which increases the amount of labor and is not conducive to the improvement of work efficiency.
