Chip breaking device of adjustable circular ultra-hard turning tool

Abstract

Disclosed is a chip breaking device of an adjustable circular ultra-hard turning tool. The chip breaking device of the adjustable circular ultra-hard turning tool comprises a chip breaking block and a blade press plate, wherein the blade press plate is fixedly installed on a tool handle. The chip breaking block is located on the upper end face of a circular ultra-hard blade, and is characterized in that the circumferential surface of the chip breaking block is spiral, the spiral line is an archimedes spiral line or a hyperbolic spiral line or a fibonacci spiral line, and a chip breaking block angle adjusting mechanism is arranged between the blade press plate and the chip breaking block. The chip breaking device of the adjustable circular ultra-hard turning tool has the advantages that due to the facts that the circumferential surface of the chip breaking block is spiral, and the chip breaking block angle adjusting mechanism is arranged between the blade press plate and the chip breaking block, the chip breaking device can rotate the chip breaking block according to different cutting working conditions of the circular ultra-hard turning tool, the chip breaking effect of the chip breaking block can be optimal, and the adaptability is good; and due to the facts that fixation of the chip breaking device can be achieved by the use of the existing blade press plate of the ultra-hard turning tool, and the original structure of the circular ultra-hard turning tool does not need to be changed, the chip breaking device is easy to process, convenient to assemble and disassemble, and low in cost, and positioning and clamping of the chip breaking device are reliable and stable.

Description

technical field [0001] The invention relates to a chip breaking device for chips in machine tool processing, in particular to a chip breaking device for an adjustable circular superhard turning tool. Background technique [0002] The chips produced during the cutting process of the machine tool will bring serious problems to the processing, such as: affecting the cutting performance of the tool, damaging the machined surface of the workpiece, causing frequent shutdowns during the machining process, and affecting production efficiency. Therefore, turning tools The solution to the chip breaking problem is one of the key technologies in engineering practice. However, because the material of superhard turning tools is difficult to process, most of the current superhard turning tools do not have chip breaking function, and there are also a few superhard turning tools with chip breakers, but the overall processing difficulty is relatively high and the processing cost is high.

Problems solved by technology

[0002] The chips produced during the cutting process of the machine tool will bring serious problems to the processing, such as: affecting the cutting performance of the tool, damaging the machined surface of the workpiece, causing frequent shutdowns during the machining process, and affecting production efficiency. Therefore, turning tools The solution to the chip breaking problem is one of the key technologies in the practical application of engineering

However, due to the difficulty of processing the material of superhard turning tools, most of the current superhard turning tools do not have chip breaking function, and there are also a few superhard turning tools with chip breakers, but the overall processing difficulty is relatively high, and the processing cost is high.

There are also chip breaking devices installed on the superhard turning tool, but the chip breaking device can only adjust the front and rear positions. For round superhard turning tools, the current chip breaking device cannot fully adapt to the circular superhard turning tool. The different processing conditions of hard turning tools make it achieve the best chip breaking effect
