Rotary cutter sharpening seat for cutter

Abstract

The invention discloses a rotary cutter sharpening seat for a cutter, comprising a base, rotating pieces, a rotary shaft and a locking piece, wherein the rotary shaft is divided into X, Y and Z rotary shafts; the Z rotating piece is provided with a lathe tool mounting hole, the center line of which is vertical to the Z rotary shaft of the Z rotating piece; the Y rotating piece is provided with a YZ middle-position hole, the center line of which is vertical to the Y rotary shaft of the Y rotating piece; the Z rotating piece is sleeved in the YZ middle-position hole, the center line of which is collinear with the axis of the Z rotary shaft; the X rotating piece is provided with an XY middle-position hole the center line of which is vertical to the X rotary shaft of the X rotating piece; the Y rotating piece is sleeved in the XY middle-position hole the center line of which is collinear with the axis of the Y rotary shaft; the center line of the YZ middle-position hole of the Y rotating piece is crossed on the X rotating piece; the base is also provided with an X rotating support; and the X rotating piece is sleeved on the X rotating support, the rotating shaft of which is collinear with the X rotary shaft of the X rotating piece. When the rotary cutter sharpening seat is used, after a tool grinding machine provided with the cutter sharpening seat is clamped and lathed, continuous multi-face grinding can be performed at any blade surface angles to finish integral lathing and blade sharpening once, the operation of clamping for multiple times is avoided, and angle space conversion is not needed; the big lathing offset when the angle is regulated is eliminated; the rigidity of the cutter sharpening seat is improved; machining errors due to the cutter relieving phenomenon are reduced; and the locking reliability is further improved to increase the convenience in use and realize the miniaturization of a matched tool grinding machine and higher blade grinding precision.

Description

technical field [0001] The invention relates to a tool clamping device of a tool grinder, in particular to a sharpening seat capable of grinding the blade after the tool rotation angle is positioned. Background technique [0002] Metalworking tools such as turning tools have edges formed by a plurality of facets at defined angles. The flank of the main cutting edge is defined by the main relief angle α o and the leading angle x r Orientation, the flank of the auxiliary cutting edge is determined by the auxiliary main relief angle α o ’ and vice leading angle x r ’ Orientation. See, the second edition of "Metal Cutting Handbook", edited by Shanghai Metal Cutting Technology Association, Shanghai Science and Technology Press, April 1984, pp. 4.19-4.21 of the first edition. [0003] Chinese Patent No. 200820086570.7 is a tool grinder, which discloses a tool grinder. The worktable of the tool grinder is equipped with a sharpening seat. The sharpening seat is used for clampin...

AI Technical Summary

Problems solved by technology

Thereby reducing sharpening efficiency and accuracy, limiting the scope of application of the tool grinder, and the miniaturization and economy of the tool grinder are also difficult to achieve

There is contact rigidity between the rotating shaft of the third rotating part and the bushing, and the rotating part will deform and deviate when the cutter head is sharpened. This shift is amplified by the distance between the rotating shaft and the cutter head. Rigidity, so that the overall structure of the sharpening seat is not rigid enough, and the sharpening phenomenon of the grinder is serious, which reduces the sharpening accuracy of the turning tool

Its locking point is on the rotating shaft of the rotating part, while the sharpening force point is at the outermost end of the sharpening seat. The distance between the rotating shaft and the outer end tool is used as a lever for the sharpening force, which can easily overcome the rotating shaft lock. The locking force of the tight point causes the loosening of the rotating parts, which reduces the sharpening accuracy of the turning tool

[0004] U.S. Patent No. 4259814 Tool sharpening machine tool sharpening machine also discloses another structure in which the two rotating axes perpendicular to each other are used to set the angle of the common car blade and grind it, but it often changes the surface during sharpening. Movement depends on the uncertainty of the reference plane, and the machining accuracy is lower
