The specific embodiment
See Fig. 4 to Fig. 5, this is novel to have frame 10, electrical control cubicles 11, hydraulic means 12, guidance panel 13 and lubricating arrangement 14, also has grinding wheel unit 20, emery wheel feed arrangement 30, grinding wheel wear compensating unit 40, wheel dresser 50, automatic charging device 60, drill bit clamping device 70, chuck feed arrangement 80 and is used for processed drill bit is carried out calibration positioned detection sensor 91.
Grinding wheel unit 20 is located on the frame, comprises grinding carriage 21, emery wheel 22 and drives the drive motors 23 that emery wheel rotates, and grinding carriage is fixedly mounted on frame, and emery wheel is connected with grinding carriage is adjustable.Emery wheel feed arrangement 30 is located on the grinding carriage, comprises driving the emery wheel feed cylinder 31 that emery wheel 22 moves in grinding carriage.Automatic charging device 60 is located at grinding carriage front side on the frame, comprise hopper 61, hopper oil cylinder 62, hopper 63, feeding rod 64 and feeding oil cylinder 65, hopper is used for depositing drill bit to be processed, the hopper oil cylinder provides hydraulic power to drive the hopper motion, hopper is used to deposit from the drill bit to be processed of hopper and as the transhipment passage of drill bit, and feeding rod and feeding oil cylinder are used for drill bit to be processed is headed in the drill bit clamping device.Drill bit clamping device 70 is located at the right side of automatic charging device on the frame, comprise chuck 71, servomotor 72, clamping cylinder 73 and brake cylinder 74, chuck is used for clamping drill bit to be processed, driven by servomotor chuck rotation, and clamping cylinder and brake cylinder are used for clamping or unclamping chuck.Chuck feed arrangement 80 is positioned at drill bit clamping device below, comprises the moving guide rail 81 and the chuck feed cylinder that support the drill bit clamping device.
This is novel also to have grinding wheel wear compensating unit 40 and wheel dresser 50, grinding wheel wear compensating unit comprises compensation mechanism 41 and compensating cylinder, be used for compensation regularly because the position deviation that abrasion of grinding wheel causes, wheel dresser comprises freeing wheel 51 and hydraulic motor 52, be used for the trimming wheel outer rim, guarantee the correction shape unanimity of emery wheel.Be provided with before the chuck of above-mentioned drill bit clamping device 70 and be used for processed drill bit is carried out calibration positioning means for positioning 91, comprise place kick, place kick oil cylinder and position sensor.
This novel production mainly comprises several process segments of charging, location, grinding and blanking in using, and relates separately to parts such as automatic charging device, grinding wheel unit and drill bit clamping device.Wherein feed the stage, a plurality of drill bits parallel of in hopper, packing into the hopper direction, the hopper oil cylinder drives hopper by piston rod and moves perpendicular to the hopper direction a high-precision self-lubricating fixed rack upper edge, when hopper motion process hopper top, a drill bit parallel with hopper can fall in the hopper in the hopper, and hopper is returned to original position.Then feeding oil cylinder driving feeding rod heads into the drill bit in the hopper in the chuck, and this moment, the chuck 71 of drill bit clamping device was an open configuration, and after drill bit to be processed headed into chuck, feeding oil cylinder drove feeding rod withdrawal origin-location, and charging is finished.
In the position fixing process, the clamping cylinder pressure release of drill bit clamping device is tightened up at the effect lower chuck of spring force, clamps drill bit.The chuck that clips drill bit rotates under driven by servomotor, the place kick of positioner continues to contact with the drill bit outer rim, because the groove structure of drill bit, when place kick is positioned at the drill groove position, the position sensor state of positioner is " leading to ", when place kick is positioned on the drill bit face of cylinder, sensor states is " breaking ", when whenever receiving second " leading to " attitude, servomotor stops operating, and drill bit stops operating, the work of principal shaft braking oil cylinder, brake disc holds out against the chuck oil cylinder by friction plate, and the drill bit direction of rotation is fixed.The work of place kick oil cylinder is raised the place kick position away from machining area, and finish the location.
In the grinding process, after bit location is fixing, the chuck feed cylinder rodless cavity pressurization of chuck feed arrangement 80, make chuck carry drill bit secretly and move to the emery wheel direction along fixed rack, stop (mechanical position limitation) after motion puts in place, the emery wheel of this moment is not also in the operating position, receiving drill bit puts in place behind the signal, the emery wheel feed cylinder 31 of emery wheel feed arrangement 30 is to the rod chamber pressurization, and driving emery wheel parts to drill bit movement and grinding drill, are finished the grinding of drill bit one one side of something along fixed rack.Control system receives after one side of something machines signal, and the pressure release of emery wheel feed cylinder rod chamber resets at spring force effect lower grinding wheel parts.Chuck feed cylinder rodless cavity pressurization drives chuck and resets, the driven by servomotor chuck and drive drill bit Rotate 180 ° after fixing, the chuck feed cylinder drives chuck once more to the motion of emery wheel direction, emery wheel is grinding once more, finishes another the half of grinding of drill bit relief angle.Principal shaft braking oil cylinder pressure release after grinding is finished, the pressure release of chuck clamping cylinder, drill bit unclamps, and finishes the grinding of drill bit.
Each parts of this novel numerical control grinding machine reset during blanking, carry out the grinding of next root drill bit, in next root drill bit feeding, the drill bit that the grinding that originally was positioned at chuck is finished ejects chuck, fall into blanking groove, promptly finish the overall process of a drill bit grinding, the equipment do action.
