摘要： The states of contact switches are switched when a mode switch is turned on. If the drilling operation is effected by means of a drill motor in this state, an oscillation signal which is repeatedly set to "H" and "L" in a preset period corresponding to an output of an oscillator is supplied to the control terminal of a firing pulse generator. The firing pulse generator interrupts supply of the control signal to the control terminal of a triac in the above preset period based on the oscillation signal supplied to the control terminal thereof to interrupt supply of an AC power source from a commercial AC power source to a bridge-type rectifier so as to intermittently drive a feed motor which is energized by an output of the rectifier in the above preset period. As a result, the drill motor can be intermittently fed towards a to-be-worked object by means of the feed motor, and, when the feeding operation is interrupted, a cutting operation can be instantaneously stopped and swarf can be cut apart.

摘要： A chip breaking device for annular cutters has a comb-shaped member fixed to the front wall of a boring machine. The comb-shaped member includes a stem extending in parallel with the annular cutter rotated by the boring machine and three or more elongated chip breaking elements extending perpendicularly from the stem and into proximity to the outer periphery of the annular cutter. Chips formed by the annular cutter hit against the chip breaking elements and their tip portions are caught by the elements. Then, intermediate portions pass through the spacings between the adjacent chip breaking elements. Thereafter the chips are pulled and broken into pieces.

摘要： A boring apparatus has a rotary member rotated by a motor, a transmission shaft transmitting its rotation to an electric drill by means of a rotation transmission mechanism for reciprocally moving the electric drill on the frame of the apparatus. The transmission shaft is selectively connected directly to the rotary member and connected operatively thereto through a coupling which is rotated reversely to the rotary member through a reduction mechanism and is designed to be disengaged from the transmission shaft when the shaft is directly connected to the rotary member and to be engaged with the shaft when the shaft is not directly connected to the roatary member. The apparatus has a selecting member which directly connects the shaft to the rotary member and disengages the coupling from the sahft. The apparatus is also provided with a switching mechanism automatically operating the selecting member to directly connect the shaft to the rotary member when the electric drill is lowered in a predetermined position.

摘要： When a start SW 3 is pressed, a one-shot multivibrator circuit 15 turns on and releases a pulse. The pulse is transmitted to a self-hold circuit 16 which in turn stays in self-hold mode and releases an H level output continuously until it is reset. This cause a transistor 17 to turn on and actuate a ram downward movement relay R1. When the ram arrives at the lower limit of its movement, a lower LS 4 is opened causing a self-hold circuit 21 to produce an H level signal in accordance with an output of a one-shot multivibrator 18. The H level signal from the self-hold circuit 21 is delayed by a delay circuit 22 and turns on a transistor 23. As the result, a ram upward movement relay R2 is actuated. Because of the function of the one-shot multivibrator circuit 15, the ram will not restart when the start SW 3 is continuously depressed. The delay circuit 22 contributes to the longer operational life of a directional valve switching mechanism. Also, a combination of another delay circuit 19 and a logical product circuit 24 is provided for preventing any fault action derived from chattering of the lower LS 4.

摘要： A drill apparatus with an electromagnet base, which has an electric drill directed downwards, is provided with an electromagnet base having an electromagnet for attaching the apparatus to a to-be-worked object by magnetic force. The electric drill is rotated by a drill motor and moved by a feed motor towards the object. A Hall element is situated on the electromagnet base. Two comparators detects whether or not a Hall voltage output from the Hall element falls in a predetermined range of voltage values. When the Hall voltage does not fall in this range, a transistor is turned on. Consequently, a relay is operated, a contact is opened, and power supply to the drill motor and the feed motor is stopped.

摘要： The operation of an electric drill is inhibited when it is interrupted by an abrupt fault such as power failure and then the fault is recovered, or when the coil of an electromagnet has a trouble such as disconnection.After the fault is eliminated with a power switch 50 remaining closed for energizing the electromagnet and the electric drill, a photocoupler 38 turns on a thyristor 31 to disable the conduction of a transistor 35. As the result, a drill motor 16 will not start before the magnetization of the electromagnet. The trouble in the coil 27 is detected by a potential examining circuit 30 measuring a potential difference across a resistor 31. The detection of the trouble causes the thyristor 31 to interrupt the conduction of the transistor 35. Accordingly, the electric drill will not start again unless it is securely anchored by the electromagnet.
