电机1(见附图)通过端面离合器3带动齿轮4和齿轮18,齿轮18使螺杆17和锥体13向下移动(用销15防止螺杆转动),从而使磨条10在校准环8中快速张开。同时,当与齿轮18连成一体的齿轮2转动时,控制系统将记下由传感器SQ1送来的脉冲数。当珩磨条碰到标准环孔壁时,螺杆17停止向下移动,在压缩弹簧6的同时,离合器的端面齿使齿轮4与圆盘5一起向下移动。圆盘5与传感器SQ2接触,使电机1停止转动,并向控制系统发出记忆从螺杆处于原始位置时磨条开始张开(这时销15靠在套14的槽中)到珩磨条碰到标准环孔壁为止这段时间内脉冲数的指令。这时电机1接
The motor 1 (see the accompanying drawings) drives the gear 4 and the gear 18 through the end face clutch 3, and the gear 18 moves the screw 17 and the cone 13 downward (pin 15 prevents the screw from rotating), so that the grindstone 10 is rapidly moved in the calibration ring 8 Open. At the same time, the control system will note the number of pulses sent by the sensor SQ1 as the gear 2 integral with the gear 18 rotates. When the honing rod hits the standard ring hole wall, the screw rod 17 stops moving downward, and while compressing the spring 6, the end face tooth of the clutch causes the gear 4 to move downward together with the disk 5. Disk 5 contacts sensor SQ2, causing motor 1 to stop rotating and memory to the control system. When the screw is in its original position, the rod starts to open (when pin 15 rests in the groove of sleeve 14) until the honing stick meets the standard Ring hole wall so far the pulse number of instructions. At this time the motor 1 access
