Specific embodiment
The invention will be further described with reference to the accompanying drawings and examples.
Such as Fig. 1, workpiece to be machined is positioned and clamped by the centre frame 3 on lathe.During Drilling operation, workpiece 2 is clamped by the chuck of main shaft and rotated under main shaft drive, and drilling rod 7 is then by saddle 9 with action feed motion.Inlet duct 4 is mounted with platen, and is tightly connected with workpiece right side by 0 shape sealing ring.Compressed air by inlet duct 4 air inlet inject, by drilling rod 7 external diameter and hole wall between gap flow into cutting region, cutter is cooled down, chip with compressed air by drill pipe bore by drilling rod afterbody export discharge.Compressed air pressure is not less than 150kPa, and cutting data can select rotating speed n=600 ~ 900 r/min, the amount of feedingf=0.05~0.09mm/r.Because drilling rod is more long, be easily deformed, thus on machine tool guideway can installation activity centre bearing, the optional position of drilling rod can be supported.
Such as Fig. 2, using PLC controls, during work, gases at high pressure are pressed into drilling and drill bit are cooled down control system by air compressor machine, and drilling cuttings is taken out of, and temperature sensor PT100 is placed at drilling rod crumb mouth.PLC passes through FX2N- 4AD-PT thermal modules obtain the temperature value of drill bit, after comparative analysis by frequency converter and feeding motor driver control respectively spindle drive motor and feeding motor, control the speed of mainshaft and drill bit the amount of feeding, with up to reduce temperature of diamond bit purpose.
Smooth to ensure cooling effect and chip removal, compressed air should keep appropriate pressure and flow.High pressure, low discharge can be used during processing Small-deep Hole；Low-pressure, big flow can be used during processing large diameter, deep borehole.Chip and hot-air are discharged from the middle of chip removal bar, and this mode chip removal effect is good.
The control program of the system is set to control and automatically control two modes manually.
In the operation of manual gear, first determine that system is opened, indices are normally and in standby mode." automatic/to stop/manual " knob is placed on " manual " position on the touchscreen, system manual work under PLC cooperations, the frequency converter of auger axis motor is not involved in work.Manually operated maintenance mode and frequency converter suitable for deep hole drilling machine is used when being out of order, also can directly drilling shallow bore hole when use.Manually boot and stop being completed by its corresponding " startup " and " stopping " button respectively, and light or extinguish indicator lamp.
