Problems solved by technology

During the processing of traditional cutting tools, the commonly used blades are diamond-shaped blades. Due to the influence of the connection mode of the cutter body and the cutter body itself, the acute-angled part of the diamond-shaped blade is used as the cutting edge during processing, and the obtuse-angled part cannot be used, and the utilization rate of the blade is low.

Abstract

The invention relates to a lathe tool, comprising a cutter bar, a cutter holder and a blade, wherein a square groove is formed in the cutter bar; a screw and a bolt are arranged in the square groove; the cutter holder is arranged in the square groove and is connected with the screw and the bolt; the screw is movably hinged to the cutter bar of two sides of the square groove; an arc groove is formed in the inner wall of the cutter bar on one side of the square groove; a plurality of limiting threaded holes matched with the bolt are formed in the arc groove; a plurality of positioning holes corresponding to the limiting threaded holes are formed in the cutter bar on the other side of the square groove; the bolt is connected with the cutter bar through the positioning holes and the limiting threaded holes; the blade is fixedly connected to an end angle of the cutter holder. The lathe tool has the characteristics of being simple in structure, capable of adjusting the angle and the like.

Description

technical field [0001] The invention relates to the technical field of mechanical tools, in particular to a lathe tool. Background technique [0002] A cutting tool is a tool used for cutting in mechanical manufacturing, also known as a cutting tool. In lathe processing, various tools are often used to process the inner circle, outer circle and annular groove of the workpiece. Such tools used for lathes are usually referred to as turning tools. Existing lathe tools need to be replaced regularly due to greater wear and tear during use. In this way, it is necessary to re-check the position of the tool, which wastes time and greatly reduces production efficiency. In practical applications, some mass-produced and uncomplicated workpieces are processed. During the processing of traditional cutting tools, the commonly used blades are diamond-shaped blades. Affected by the connection mode of the cutter body and the cutter body itself, the acute-angled part of the diamond-shaped b...
