This is an electric control mechanism, and in the drill rotation/grinding motion control mechanism, a circular table is rotated by a table rotation motor on a belt tensioner, and a mark is placed on the outer peripheral wall of the table, and the table rotation speed is determined by a detection part b. The grinding wheel is rotated at an eccentric position from the drill chuck in the center of the table on a belt tensioned belt by the grinding wheel rotation motor, and the belt connecting the grinding wheel shaft and the grinding wheel rotation motor is The grinding wheel rotation speed is detected by the detection part a, and the grinding wheel vertical and horizontal movement control mechanism detects the amount of horizontal movement of the grinding wheel vertical movement cam and the grinding wheel horizontal movement cam fixed to the outer periphery of the peripheral wall of the table. , a swinging lever, a switching lever, a transmission shaft, a transmission lever, a connecting rod, a vertically moving L-shaped lever, etc. are used to transmit the information to the engagement plate fixed to the lower end of the quill in which the grindstone shaft is loosely fitted in a rotatable state. is transmitted to the spindle housing loosely fitted so that the quill moves up and down vertically through a follower roller, horizontal movement lever, connecting rod, etc. On the other hand, the amount of rotation is reduced and captured by a Geneva foil according to the amount of table rotation. The grinding wheel is connected to one end of the vertically movable L-shaped lever via a bevel gear and a connecting rod, and the grinding wheel is moved slightly upwards, and this movement is stored in a power storage spring spring provided at the other end of the connecting rod. When the grinding process is completed, the stored force is released, and for fine adjustment of the vertical amount of the grinding wheel, a slider with a pin facing the groove of the transmission shaft with a spiral groove is attached to the transmission shaft. The slider can be adjusted up and down by rotating the grinding wheel adjustment handle that is located at a position that protrudes from the top surface of the transmission shaft. The drill stopper's blade abutments are arranged at a constant interval, and the drill stopper is fixed to the upper end of the rotation shaft so that the blade abutments rotate between a position corresponding to the lower end of the chuck and a release position. An operating lever is installed at the lower end of the shaft, and by the action of a solenoid and a coil spring, the drill stopper is placed in the position corresponding to the lower end before and after the grinding operation, and in the release position during the grinding operation, and is electrically controlled. In the mechanism, the input/output elements are power on/off, amount of grinding of the drill, number of rotations of the grinding wheel,
Turning the start switch on and off, turning the solenoid power on and off,
It controls the start and stop of table rotation and the start and stop of grinding wheel rotation. A small drill grinder configured with a mechanism. (2) In the scope of the utility model registration claim, the fine adjustment of the vertical amount of the grinding wheel in the grinding wheel vertical/horizontal movement control mechanism set forth in Paragraph 1 involves correction of the grinding wheel that is above the connecting rod shaft length and protrudes to the side of the machine box. A small drill grinder that can be adjusted with a handle.
