Embodiment Construction

[0017] The specific implementation manners of the present invention will be further described below in conjunction with the drawings and examples. The following examples are only used to illustrate the technical solution of the present invention more clearly, but not to limit the protection scope of the present invention.

[0018] 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.

[0019] The cutting part of the turning tool is composed of the main cutting edge, the auxiliary cutting edg...

Abstract

The invention relates to a lathe tool with an extension-type tool bit. The lathe tool comprises a tool body, a channel which penetrates the tool body is formed in the tool body, a toolbar which can slide in the length direction of the channel is installed in the channel, a push rod bolt which can push the toolbar to move in the channel penetrates one end of the channel, the push rod bolt abuts against the end portion of the toolbar, the tool body is provided with a positioning bolt which penetrates the tool body and abuts against the toolbar, a mounting groove is formed in the end portion of the toolbar, a positioning groove is formed in the bottom of the mounting groove, a tool bit is fixed in the mounting groove, and a protrusion part matched with the positioning groove is formed on the tool bit. The channel which penetrates the tool body is formed in the tool body, the toolbar which can slide in the length direction of the channel is installed in the channel, in this way, the tool body can slide along the channel, and therefore extension function is achieved.

Description

technical field [0001] The invention relates to the field of mechanical processing equipment, in particular to a turning tool capable of retracting the tool head. 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 ...
