Pointed tooth cutter be have the number of teeth many, cut sharp, cutting effect is good a little, be widely used in the milling of various more shallow axial trough in machining, the relief angle of pointed tooth cutter is the angle after cutter and between cutting plane, it can make cutting edge sharp, reduce the friction after cutter and between surface of the work, suitable relief angle can reduce cutting vibration.
Concrete grammar method first with cylindrical grinder, the cutting tip excircle configuration of sharp teeth profile milling cutter is ground, and then slotting cutter is ground on cutter and tool grinding machine the relief angle of slotting cutter with flaring cup wheel.When grinding the relief angle of slotting cutter, the excircle part of slotting cutter be left the rib of a 0.1 ~ 0.2mm, making sharp teeth profile milling cutter when Milling Machining part, the roughness milling out the surface come can be very high, can not leave the tool marks of a lot of.The workman that whole process need technical merit is higher completes, and just can grind the relief angle comparatively meeting specification, and labor strength is large, efficiency is low.
Summary of the invention
The invention is intended to provide that a kind of quality is high, efficiency is high and the knife milling tool circular arc relief angle frock that labor strength is low.
Technical scheme in this programme is: knife milling tool circular arc relief angle frock, be installed on the grinding machine of processing sharp teeth profile milling cutter, comprise horizontal base, it is characterized in that, this base is provided with spindle hole, have main shaft by bearing fit in this spindle hole, main shaft end and base are fixed by round nut, and main shaft end is provided with rear turning handle; The front end lock-screw of main shaft is fixed with reversing frame, and this reversing frame is fixed with front turning handle, base is provided with and is positioned at reversing frame both sides for a pair and the gag lever post that can limit reversing frame rotational angle; Described reversing frame has vertical groove, and these groove two ends are provided with two adjustment bolts, and be fixed with knife rest between two adjustment bolts, this knife rest is removably connected with cutter shaft, and this knife rest end is fixed with the anti-bull stick that can prevent sharp teeth profile milling cutter from rotating.
The beneficial effect of this programme is: the present invention is with the main shaft that can rotate in spindle hole, the rear turning handle of main shaft end can control main shaft and rotate, front-end of spindle is fastened with reversing frame, front turning handle on reversing frame also can control main shaft and rotate, reversing frame can rotate along with the rotation of main shaft, excessively cause mill relief angles lack of standardization in order to reversing frame rotates, the gag lever post of the rotational angle of reversing frame can be limited for a pair that base is arranged; Reversing frame is undertaken adjusting and fixing by the position of adjustment bolt cutter setting frame, and knife rest can change dissimilar cutter shaft according to different sharp teeth profile milling cutter models, and anti-bull stick can clamp and make pointed tooth cutter, prevents it from rotating when grinding relief angle.The present invention can the angle of zygodont milling cutter, position adjust, and makes the one-shot forming of grinding-wheel grinder relief angle and can ensure machining accuracy, improve operating efficiency, reduce labor strength.
Further, described anti-bull stick comprises the screw rod inserting knife rest, and the dop vertical with this screw rod, and dop can prevent sharp teeth profile milling cutter from rotating, and makes grinding-wheel grinder relief angle more accurate.
Further, main shaft also overlaps outward main shaft distance bushing, can regulate play and the precompressed of bearing.
Further, base bottom is provided with the keyway for being connected with grinding machine, makes the position between base and grinding machine adjustable.
