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.
