Hydraulic height-adjustable turning tool

Abstract

The invention discloses a hydraulic height-adjustable turning tool which comprises a tool body. The tool body is provided with a plurality of sets of hydraulic height adjusting mechanisms, each hydraulic height adjusting mechanism comprises a first oil cylinder which is a cylinder hole located between the two opposite upper and lower bottom faces of the tool body in the axial direction, a piston is arranged in each first oil cylinder, the end of each piston penetrates an end cover, a rubber ring is further arranged between each end cover and a groove, one side of each first oil cylinder is sequentially provided with a second oil cylinder and a hydraulic oil storage cavity, a push-and-pull type valve is arranged in each second oil cylinder, a first oil pipe communicating with the front endof the top of each second oil cylinder is arranged at the upper portion of the corresponding first oil cylinder, a third oil pipe and a fourth oil pipe are arranged at the bottom of each second oil cylinder and communicate with the corresponding hydraulic oil storage cavity, a supporting frame is arranged outside the tool body in a sleeving manner, rectangle through grooves are formed in the sidewall of the supporting frame, the ends of the push-and-pull type valves penetrate the rectangle through grooves, and handles are installed at the ends of the push-and-pull type valves. By means of thehydraulic height-adjustable turning tool, the center height of the turning tool can be quickly adjusted.

Description

technical field [0001] The invention belongs to the technical field of turning tools, and in particular relates to a hydraulically height-adjustable turning tool. Background technique [0002] Lathes, including ordinary lathes and CNC lathes, require that the tip of the tool must be at the center height of the rotating part during processing, otherwise the actual rake angle and rear angle of the cutting tool will be changed, or the part cannot be cut during cutting, and it is very easy to cause For cutting tools, the center height of the tool is fixed after the traditional tool is manufactured. For welded turning tools, after the tool is sharpened, especially after the rake face is sharpened, the actual center height of the installed tool will become lower. The traditional method is to use some gaskets with different thicknesses for installation and adjustment. This method is time-consuming and laborious to adjust the center height, and because the flatness of the gaskets af...

[0002] Lathes, including ordinary lathes and CNC lathes, require that the tip of the tool must be at the center height of the rotating part during processing, otherwise the actual rake angle and rear angle of the cutting tool will be changed, or the part cannot be cut during cutting, and it is very easy to cause For cutting tools, the center height of the tool is fixed after the traditional tool is manufactured. For welded turning tools, after the tool is sharpened, especially after the rake face is sharpened, the actual center height of the installed tool will become lower. The traditional method is to use some gaskets with different thicknesses for installation and adjustment. This method is time-consuming and laborious to adjust the center height, and because the flatness of the gaskets after repeated use is not good, especially after the combination of multiple pieces, due to the The flatness of the sheet is not good, and it will cause the phenomenon of unreliable installation when the screw is tightened
