Turning tool with pushing mechanism

Abstract

The invention relates to a turning tool with a pushing mechanism. The turning tool comprises a tool body, wherein a cavity structure is formed in the tool body; the tool body is internally provided with a tool rod capable of sliding along the axial direction of the tool body; a tool bit is arranged at the end part of the tool rod; a positioning bolt, which penetrates into the cavity, is arranged on the tool body; the positioning bolt is in butt joint with the tool rod; the pushing mechanism is further arranged at one end of the tool body; the pushing mechanism comprises an adjusting device, a push rod connected to the adjusting device and an ejection block fixed at the end part of the push rod; and the ejection block is in jacking joint with the end part of the tool rod. The pushing mechanism is further arranged at one end of the tool body and the tool rod in the tool body is pushed and pulled through the pushing mechanism, so that the displacement of the tool bit is realized. The pushing mechanism comprises the adjusting device, the push rod connected to the adjusting device and the ejection block fixed at the end part of the push rod; the ejection block is in jacking joint with the end part of the tool rod; and the accurate displacement of the push rod can be realized through fine adjustment of the adjusting device, so that the accurate displacement of the tool bit is driven and the turning precision is greatly improved.

Description

technical field [0001] The invention relates to the field of machining equipment, in particular to a turning tool with a propulsion mechanism. Background technique [0002] Types and uses of turning tools Turning tools are the most widely used single-edged tools. Turning tools are used on various lathes to process outer circles, inner holes, end faces, threads, grooves, etc. According to the structure, turning tools can be divided into integral turning tools, welding turning tools, machine clamp turning tools, indexable turning tools and forming turning tools. Among them, the application of indexable turning tools is becoming more and more extensive, and the proportion of turning tools is gradually increasing. [0003] The cutting part of the turning tool is composed of the main cutting edge, the auxiliary cutting edge, the rake face, the main flank face and the auxiliary flank face, and the tool nose angle. The combination of the cutting part and the shank of the turning...

Problems solved by technology

[0004] When the existing turning tool is used on the lathe, the feed amount of the turning tool is controlled by the lathe itself. Due to the limitation of the precision of the lathe itself, the control of the dimensional accuracy of the parts is not very ideal. Dimensional accuracy requires other finishing processes, such as grinding, to obtain the dimensional accuracy of the required parts. Such parts processing technology is very uneconomical and the production efficiency is low, which cannot meet the current low-consumption and high-efficiency production. skills requirement
