Abstract

The utility model discloses an edge grinding machine for a sample board cutter, which is composed of a rotary sander 1, a lathe supporting plate, a machine frame 3 and a knife frame 4. The upper part of the lathe supporting plate 2 is provided with a rotary working bench, and the knife frame 4 is vertically fixed to the rotary working bench. The utility model has the advantages of high grinding speed, high precision, low rejection rate and the convenient operation. The utility model not only can grind a sample board cutter in the shape of a circular arc, but also can grind a convex and concave sample board cutter in a tool sharpening mode.

Description

Radius gauge blade grinding machine

The utility model belongs to a kind of form tool cutting edge sharpening machine, specifically a kind of radius gauge blade grinding machine.

Machine-building often runs into the car mill processing of circular arc raceway groove on internal diameter, external diameter or the end face at revolving body, the circular arc molding lathe tool grinding method of this class workpiece of turning has several: the one, on cutter and tool grinding machine, use the forming grinding wheel sharpening, because of lathe tool has anterior angle and relief angle, the profile of emery wheel is not a circular arc accurately, so the correction of the flank shape difficulty of emery wheel is bigger; The 2nd, carry out sharpening with the Ellipse explorator method, but complicated movement is adjusted inconvenience, also difficult the realization.Therefore, normally on the normal sands turbine, grind tooth shape, but hand grinding is difficult to grind the circular arc tooth shape that meets required precision, percent defective height by model, waste time and energy, for this reason, the technical staff has done many improvement, but have too complicated again, not easy to operate, cost height, function singleness.

The purpose of this utility model is to provide a kind of easy operation, yield rate height, excellent in efficiency, accuracy height, low being exclusively used in of cost to grind the radius gauge blade grinding machine of the circular arc form tool of certain curvature, and this radius gauge blade grinding machine also can grind the convex concave form tool.

The utility model is achieved in that this radius gauge blade grinding machine is made of abrasive machine, lathe tray, frame, knife rest, the support of its abrasive machine is vertically fixed on the frame, rotary table is established on lathe tray top, knife rest is vertically fixed on the rotary table, vertically moving of longitudinal screw control knife rest on the lathe tray, laterally moving of transverse screw control knife rest on the lathe tray, the rotational angle of rotary table control knife rest, also be provided with radian control slide block in the knife rest bottom, in order to adjust the distance of knife rest and grinding wheel, the radian of control cutter.This radius gauge blade grinding machine is also implemented by following measure: its rotary table is by gear turntable, the chassis, the gear screw rod constitutes, the central shaft hole of gear turntable is contained on the turning cylinder, turning cylinder is fixed on the chassis, the chassis is fixed on lathe tray top again, the peripheral teeth of gear turntable and gear screw engages, gear turntable rotates, thereby drive blade holder turns, gear turntable can back and forth rotate, drive blade swing sharpening, the radian control slide block of knife rest bottom is connected with dovetail draw-in groove form with gear turntable, and radian control slide block is provided with vernier knob, by adjusting vernier knob, the distance of control blade and grinding wheel.Using this uses when novel, can be earlier after having roughly ground the profile of blade on the normal sands turbine, be contained on the knife rest lathe tool also fastening, back and forth rotate the gear turntable on the rotary table, knife rest can be along the vertical axis reciprocally swinging, thereby grind the circular arc cutting edge, adjust the vernier knob on the slide block, can change the distance of cutting edge and grinding wheel, thereby change the Arc Blade Lathe Tool radius value, rotate the transverse screw on the lathe tray, can make blade leave grinding wheel, then can when sharpening finishes, after meeting required precision, not unload lathe tool again with the model check.If grind the convex concave form tool, can change the mode of operations and to grind.

The utility model has the advantages that: the speed that grinds is fast, precision is high, percent defective is low, profitable, cost is low, and easily operation can not only sharpening radius gauge cutter, but also can grind the convex concave form tool.

Below in conjunction with accompanying drawing the utility model is described in further detail.

Fig. 1 looks schematic diagram for the utility model master.

Make the utility model with reference to accompanying drawing 1.This radius gauge blade grinding machine is made of abrasive machine 1, lathe tray 2, frame 3, knife rest 4, the support of abrasive machine 1 is vertically fixed on the frame 3, rotary table is established on lathe tray 2 tops, knife rest 4 is vertically fixed on the rotary table, vertically moving of longitudinal screw 6 control knife rests 4 on the lathe tray 2, laterally moving of lateral rotation screw rod 7 control knife rests 4 on the lathe tray 2, the rotational angle of rotary table control knife rest 4, also be provided with radian control slide block 8 in the bottom of knife rest 4, in order to adjust the distance of knife rest 4 and grinding wheel.Rotary table is made of gear turntable 5, chassis 9, gear screw rod 10, the central shaft hole of gear turntable 5 is contained on the turning cylinder, turning cylinder is fixed on the chassis 9, chassis 9 is fixed on lathe tray 2 tops again, the peripheral teeth of gear turntable 9 and 10 engagements of gear screw rod, transmitting gear screw rod 10 can make gear turntable 5 rotate, the radian control slide block 8 of knife rest 4 bottoms is connected with dovetail draw-in groove form with gear turntable 5, radian control slide block 8 is provided with vernier knob 11, the distance of control blade and grinding wheel, the radian of control cutter.
