A multifunctional boring tool

Abstract

The invention discloses a multifunctional boring cutter which comprises a cutter body and a cutter rod. The tail portion of the cutter body is conic. The cutter rod is perpendicularly arranged on the upper portion of the cutter body. The diameter of the cutter rod ranges from 40 mm to 160 mm. The upper portion of the cutter rod is of a fan blade shape. The number of blades is three. The edges of two symmetric blades are provided with milling cutter grooves. Milling heads are fixed to the milling cutter grooves through clamping bolts. An installation groove is formed in the portion between the two milling cutter grooves in the direction of a 90-degree angle formed by the edges of the blades. A small cutter holder is fixed to the installation groove. A countersunk head regulating screw is arranged on the end face, close to the inner side of the installation groove, of the small cutter holder. A triangular boring cutter groove is formed in the small cutter holder. A boring head is fixed to the inner portion of the boring cutter groove through a clamping bolt. A U-type through hole is formed in the small cutter holder. A cutter tip of the boring head extends out of the circumference of the cutter rod for 1 mm to 3 mm. Scrap discharging grooves are formed in the spaced portions of the blades. A cutting installation hole is formed in the cutter rod. An outlet is formed in the middle of the blades. A cutter outlet hole is formed in the side face of the cutter rod. The multifunctional boring cutter is multifunctional, a drill bit, a milling cutter and the boring cutter can be clamped and can not influence one another, and a regulating mechanism is arranged, so that the machining size is adjustable, the machining range is wide, use is convenient, efficiency is improved, a cutter body can be shared by the cutters, and cost is saved.

Description

technical field [0001] The invention relates to a cutting tool, which belongs to the technical field of metal cutting, and in particular to a multifunctional boring tool. Background technique [0002] In the process of mechanical processing in the factory, it is often multi-process processing, which requires tools and tool sets such as drills, milling cutters, and boring tools. Cutters that can hold the same shank cannot be used universally, which brings inconvenience to the work. Contents of the invention [0003] In order to solve the above problems, the present invention discloses a multifunctional boring cutter, which can hold drill bits, milling cutters and boring cutters, has a wide processing range and is easy to use. [0004] To achieve the above object, the technical scheme of the present invention is as follows: [0005] A multi-functional boring tool, including a cutter body and a cutter bar, is characterized in that: the tail of the cutter body is conical, th...
