Fig. 2 is the round as a ball basal plane grinding machine of a LED sapphire of the present invention numerical control schematic top plan view.
The specific embodiment
See Fig. 1, Fig. 2, the round as a ball basal plane grinding machine of a kind of LED sapphire numerical control, it comprises lathe bed 1, workbench 2, is installed in base 3-1, the 3-2 at two ends, lathe bed rear portion; Workbench 2 is last through rail plate 4-1,4-2 that ball-screw 22 is installed on lathe bed 1 front portion; Ball-screw 22 drives through servomotor 21, and workbench is provided with the headstock 12 and is respectively arranged with line slideway 15-1,15-2 and 15-3,15-4 with 13, two base 3-1 of tailstock, 3-2 two ends; Two feeding planker 5-1 and 5-2 respectively through ball-screw 20-1 and 20-2 be installed in line slideway 15-1,15-2 and 15-3,15-4 is last; Ball-screw 20-1 and 20-2 drive through servomotor 19-1,19-2 respectively, are separately installed with flat-faced wheel grinding head 24-1 and cylindrical abrasion wheel grinding head 24-2 on feeding planker 5-1 and the 5-2, and flat-faced wheel grinding head 24-1 comprises grinding wheel drive mitor 23; Grinding wheel drive mitor 23 is installed on the grinding carriage 10; The grinding wheel drive mitor axle connects grinding wheel spindle 11, and diamond flat-faced wheel 9 connects grinding wheel spindle 11, and grinding wheel spindle 11 is perpendicular to the headstock 12 and tailstock 13; Cylindrical abrasion wheel grinding head 24-2 comprises grinding wheel drive mitor 16; Grinding wheel drive mitor 16 is installed on the grinding carriage 7, and grinding wheel drive mitor 16 passes through belt 25 is connected grinding wheel spindle 8 with belt pulley 26,27 input, and diamond cylindrical emery wheel 6 connects the output of grinding wheel spindles 8; Grinding wheel spindle 8 is parallel to the headstock 12 and tailstock 13; The headstock 12 inboards are provided with and fixedly hold out against a 14-1, and tailstock 13 inboards are provided with hydraulic pressure and hold out against a 14-2, and the sapphire workpiece is supported between the headstock, the tailstock by said hydraulic pressure holding device.
During workbench 2 feedings; Sapphire workpiece 17 is supported between the headstock 12, the tailstock 13 by holding device 14; The headstock 12 clamps 17 feedings of sapphire workpiece with tailstock 13, during sapphire workpiece process cylindrical abrasion wheel grinding head 24-2, carries out cylindricalo grinding through the 6 pairs of sapphire workpiece of diamond cylindrical emery wheel 17 on the cylindrical abrasion wheel grinding head 24-2; Workbench 2 continues feeding; When the part that cylindricalo grinding finishes on the sapphire workpiece is passed through flat-faced wheel grinding head 24-1, carry out the datum level grinding, realized on same grinding machine through 9 pairs of sapphire workpiece of the diamond flat-faced wheel on the flat-faced wheel grinding head 24-1 17; Table feed has once carried out cylindricalo grinding and datum level grinding to the sapphire workpiece.
The lathe bed left end is installed a laser orientation measurement mechanism 18, after being used for cylindricalo grinding and finishing, measure sapphire and find out only datum mark, and mill processes true edge.
Because cylindrical grinding, mill true edge are processed by different wheel grinding modes respectively, respectively get the chief, and be with strong points.The cylindrical of skive and the grinding of sapphire workpiece, because diamond cylindrical grinding wheel diameter is bigger, under same stock removal situation, it is less that the unit diamond grit is cut surplus sapphire amount, so the life-span of diamond cylindrical emery wheel is longer; Keep same unit diamond grit to cut under the surplus sapphire amount situation, can improve grinding efficiency; Because its grinding speed of cylindricalo grinding method is big, can improve the grinding fineness of sapphire surface, grinding accuracy is high, and end product quality is improved.But mill true edge cylindrical emery wheel can not be completed processing tasks, so accomplished by flat-faced wheel, the utilization of laser orientation measurement mechanism makes processing technology more reasonable.
What adopt among the embodiment is sapphire cylindrical of LED and datum level grinding; Certainly so long as on a grinding machine; A clamping round bar shape material; And the round bar shape material carried out cylindricalo grinding and the datum level grinding can be adopted above-mentioned grinding machine structure, as long as two grinding wheel spindles parallel with the headstock respectively with tailstock and vertical all be the scope that structure of the present invention is protected.
