摘要:
A tool, a device, and a method for drilling capable of very easily forming a hole part in a drilled matter by extreme-smoothly discharging chips produced at drilled positions so as to maintain an excellent drilling efficiency, wherein, by using a drilling tool having a shaft with a spiral groove part formed in the outer peripheral surface thereof and a bit fixed to the tip part of the shaft, the hole part is formed in a drilled matter by rotating the shaft at a high speed, whereby the chips can be discharged since air flow is generated by the high speed rotation of the spiral groove part.

An exhauster device applicable to manual drills, formed by an exhaust member operated by the motor of the drill, comprising a telescopic exhaust tube (1-2) running parallel to and beneath the body of the drill and of the bit (62) thereof, provided with an inner spring (5) tending to keep it distended at the level of the end of the bit so that it is always located beneath the work area; said tube ends in a collection scoop (3) provided with a top opening (31) in which dust or wastes released by the same fall; said scoop (3) has a connection with the exhaust tube (2) in the intermediate area and a receptacle (34) in the bottom portion for the byproducts falling into it, and means (43) in the front area for adhering to the surface on which the drill is operating.

A method for drilling a hole in a work piece, such as printed circuit boards, comprises drilling to a point in a work piece and retracting said drill bit a retract distance. The retract distance is configured such that a tip end of said drill bit remains below a top surface of said work piece. The method further comprises drilling a distance greater than said retract distance into said work piece.

Feste oder flüssige Rückstände in Hohlräumen wie bei spielsweise Bohr- und Gewindeschneidspäne sowie beim Bohren oder Fräsen verwendete Kühl- und Schmierflüssig keiten werden erfindungsgemäß dadurch entfernt, daß ein unter Druck stehendes Gas als eng gebündelter Strom in den Hohlraum eingeblasen und aus dem Hohlraum über dessen vollen Öffnungsquerschnitt geführt abgesaugt wird. Dadurch wird vermieden, daß die abzuführenden Fremdkörper frei durch die Atmosphäre wirbeln und die Bedienungsperson gefährden. Eine hierfür geeignete Vorrichtung besteht aus einem gegen die Hohlraumöffnung anstellbaren Saugrohr, in welchem mindestens ein in den Hohlraum einführbares Blasrohr angeordnet ist. Besonders zweckmäßig ist die Aus bildung des Saugrohrs als Ejektor mit der Möglichkeit, das eingeblasenen Gas vom Arbeitsgas des Ejektors abzuzwei gen.

A foreign object debris (FOD) collection drill attachment 14 for attaching to a drill includes a drill guide bushing holder 16, a chip breaker bushing 26, an air supply line 18, a chip evacuation line 20, a chip collection hopper 22, and an air manifold 24. The drill guide bushing holder includes an inlet channel 34 receiving air from the air supply line, an outlet channel 36, and a holder center channel 38. The inlet channel and the outlet channel each open into the holder center channel through which an end protrusion 64 of the chip breaker bushing extends to break up FOD on a drill bit 30 of the drill. The cross-sectional area of the inlet channel is smaller than the cross-sectional area of the outlet channel, creating a Venturi effect between the inlet channel and the outlet channel to pull FOD away from the drill bit and through the chip evacuation line to the chip collection hopper.

The present invention improves dust collection performance while suppressing an increase in body size. A dust collection device 40 comprises: an intake pipe 53 connected to a suction unit 52; a cyclone unit 60 that swirls air flowing out from the intake pipe 53 and centrifuges dust; and a filter unit 70 that accommodates a filter 72. The filter unit 70 has an outlet 74 connected to the cyclone unit 60 and discharging the air having passed through the filter 72. Therefore, the air and dust near a tip tool T can be separated by the cyclone unit 60. Furthermore, even when the dust remains, the remaining dust can be removed by the filter 72. Furthermore, the intake pipe 53 and the cyclone unit 60 are arranged at positions where the intake pipe 53 and the cyclone unit 60 overlap in a front-rear direction, and the filter unit 79 is disposed behind the cyclone unit 60. Therefore, as compared to a case where the filter unit 70 is disposed below the cyclone unit 60, an increase in the body size of the dust collection device 40 in the vertical direction can be suppressed.
