Grinding device for cutter slot

Abstract

The invention provides a grinding device for a cutter slot, which belongs to the technical field of machine tool manufacture and solves the problems of no flexible rotation of a spindle, low machining efficiency, small machining and application range and the like of the traditional grinding device for a cutter slot. The grinding device for a cutter slot comprises a spindle, a compression bar and a supporting seat arranged on a worktable of a machine tool, wherein the spindle is in a cylinder shape and is penetrated on the supporting seat; the compression bar penetrates through the supporting seat along the radial direction of the spindle; one end of the compression bar near the spindle is fixedly connected with a pressure bearing, the outer cycle of which can be in contact with the outer surface of the spindle; and the other end of the compression bar, far from the spindle, is connected with a regulating mechanism which can regulate a deflection angle between the axis of the pressure bearing and the axis of the spindle. The invention has the advantages of convenient operation, high regulating efficiency, good regulating flexibility, wide machining range and the like.

Description

technical field [0001] The invention belongs to the technical field of machine tool manufacturing, and relates to a grinding device for cutter grooves, in particular to a grinding device for processing grooves of cemented carbide cutters. Background technique [0002] The machining of carbide tool grooves is generally done on a grinding machine, and the machining of carbide tool grooves is the part with the largest amount of tool processing. At present, the high-precision multi-axis tool grinding machines used in China are almost all imported from Germany and the United States. The precision of the moving parts in these multi-axis tool grinding machines is very high, and equipped with three-dimensional tool grinding simulation software, the tool can be used at one time. Processing and forming, high production efficiency, and high precision of the produced knives. Of course, the price of imported multi-axis tool grinders is quite high, most of which are more than one million...

AI Technical Summary

Problems solved by technology

[0006] The above tool groove grinding device adopts a friction plate fixing mechanism, the friction between the friction plate and the main shaft is large, the rotation of the main shaft is not flexible, the grinding efficiency of the tool groove is not high, and the above device can only adjust the friction plate and the main shaft The angle between the two axes makes it consistent with the helical angle of the tool groove, that is, it can only realize the horizontal movement of the groove during the rotation of the tool, but cannot realize the rotation of the spindle in other directions, and cannot process other angles on the tool. small range
