Clamping and cooling device for manual sharpening of external turning tool

Abstract

The invention provides a clamping and cooling device for manual sharpening of an external turning tool. The clamping and cooling device comprises a clevis, a clamping sleeve, a cavity, a liquid filling port, a liquid storage cavity, a fixed seat and a fixed ring. The lower end of the clevis is in threaded connection with a clamping bolt, a support column is fixedly connected above the clevis, a connecting column is rotatably connected above the support column, and the clamping sleeve is fixedly connected above the connecting column. The cavity and the liquid storage cavity are opened inside the clamping sleeve. The fixed ring is inserted into an opening, and the other end of the cavity is fixedly connected with the fixed seat. The liquid filling port is opened in the upper right side of the liquid storage cavity. The external turning tool is clamped inside the fixed ring and the cavity. The fixed ring includes a clamping block, an elastic layer and a clamping hole. By means of matchingof the fixed ring, the fixed seat and the clamping sleeve, the external turning tool can be inserted into the clamping hole inside the fixed ring, and then the fixed ring and the external turning tool are inserted into the clamping sleeve. The clamping sleeve can be held to sharpen the external turning tool, scalding during the sharpening can be avoided, and the sharpening efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of manual sharpening of outer circle turning tools, and more specifically relates to a clamping and cooling device for manual sharpening of outer circle turning tools. Background technique [0002] Manual sharpening of turning tools is a technology that must be mastered by machining operators and craftsmen, and manual sharpening of turning tools is also an indispensable learning content in the metalworking practice of engineering students. Many problems will be encountered. For example, the friction between the turning tool and the grinding wheel will generate high temperature and high heat during sharpening. If the temperature is too high, the tool will anneal, and the annealing of the tool will affect the strength and service life of the tool. When sharpening a knife, it is necessary to hold the knife on the grinding wheel with both hands. The high temperature and high heat generated during the sharpening ...
