6. the ceramic core internal hole grinder according to the arbitrary claim of claim 1 to 5, it is characterized in that: described control system comprises PLC, be provided with in PLC and comprise pulling force sensor Signal reception comparison module, move back and forth frame Stroke Control module, move back and forth frame grinding stroke measurment module, grinding counting module, described rotating driving device is motor, the output wheel of motor drives driving wheel by synchronous belt, moving back and forth frame is arranged on the guide rail on board, described reciprocating movement driving device is servomotor, the output of servomotor is connected with toothed synchronous belt, move back and forth on frame and be fixedly connected with the profile of tooth block coordinated with toothed synchronous belt, control system is by controlling the rotating of servomotor and rotating the direction of motion and the stroke that the number of turns controls to move back and forth frame, before grinding, first after on the thin segment of grinding steel wire, multiple ceramic insertion core loaded onto by cover, the rear end of grinding steel wire is fixed on the pulling force sensor moving back and forth frame one end, the other end of grinding steel wire is through card hand, be fixedly connected on the pulling force sensor of the reciprocating motion frame other end after centre bore on mandrel, during ceramic insertion core material loading, control system control card hand is closed to ceramic insertion core and cannot passes through from two claw pieces, PLC moves back and forth frame motion according to the length drives of ceramic insertion core makes the ceramic insertion core of foremost just to card hand place, control system controls claw and opens, PLC control reciprocating motion frame moves forward certain displacement makes ceramic insertion core enter into two claws, after two claws close and block ceramic insertion core, PLC controls to move back and forth the pulling force that frame moves to pulling force sensor backward and reaches setting value, at this moment the conical section grinding steel wire is stuck in the endoporus of ceramic insertion core, control system controls two claws and opens, PLC controls linear reciprocation drive unit and moves forward and withstand core back-end the port part of spring chuck is opened, PLC controls to move back and forth frame and moves forward certain distance to spring chuck place, PLC controls linear reciprocation drive unit and moves backward, mandrel under the effect of holddown spring backward movement make ceramic insertion core be clamped in spring chuck, PLC controls grinding material box rising makes grinding steel wire touch abrasive material, rotating driving device drives fixture to drive ceramic insertion core to rotate, grinding steel wire tapered portion backward movement start to grind the endoporus of ceramic insertion core, move backward to a certain degree at grinding steel wire, active force between the tapered portion of grinding steel wire and ceramic insertion core transfers to PLC by pulling force sensor, pulling force sensor Signal reception comparison module in PLC carries out numeric ratio and judges to determine whether reach the heterodromous force value of grinding steel wire more afterwards, grinding steel wire is moved back and forth in the endoporus of ceramic insertion core and realizes automatic grinding, when the aperture of grinding reaches required value, in the process of grinding steel wire motion backward next time, its tapered portion will not be subject to the resistance of ceramic core internal hole, move back and forth frame stroke by the control of not tension force sensor signals, have the sudden change that one stroke is larger, when PLC reciprocating motion frame grinding stroke measurment module detects that the trip suddenlys change, stop grinding, start discharging and next ceramic insertion core material loading.
7. ceramic core internal hole grinder according to claim 3, is characterized in that: the described linear reciprocation drive unit along mandrel axially-movable arranged at mandrel holddown spring stopper rear is cylinder or linear electric motors or cam or electromagnet.
8. ceramic core internal hole grinder according to claim 5, is characterized in that: the lifting drive that described grinding material box connects is cylinder or linear electric motors or cam or electromagnet.
