In this case, the second adsorption unit has an adsorption force smaller than the adsorption force of the first adsorption unit 234, and the adsorption operation of the second adsorption unit can be turned on when the first adsorption unit 234 is off, The additional attachment portion can easily adjust the distance between the tool 10 and the machining position of the workpiece before the tool 10 is fixedly placed against the machining position of the workpiece by the attachment portion 230 . As the second adsorption unit, a magnet, a vacuum press plate, or the like may be used.

In other words, when the drilling machine 200 is used to carry out the work, a great repulsive force is generated in the drilling machine 200 in the course of work. The attachment portion 230 provides an adhesive force to allow the drill portion 20 to stably attach to the working position of the workpiece in the course of work. The drill apparatus 200 is generally weighted to some extent even if it is light enough to be carried by one person. Therefore, the operator needs to move the tool 10 several times in order to accurately face the tool 10 at the machining position of the workpiece. The tool 10 may be displaced by the strong attachment force of the attaching portion 230 in the process of using the attaching portion 230 having a strong adhesive force to oppose the tool 10 to the machining position of the workpiece . Since the additional attachment portion described above has a lower attraction force than the attachment portion 230, the attraction operation of the attachment portion 230 is turned off in the process of opposing the tool 10 to the machining position of the workpiece, It is possible to have an advantage that the tool 10 can be more easily and accurately confronted when the tool 10 is opposed to the machining position of the workpiece by utilizing the attaching portion.

The tapping operation unit 270 is connected to the drill unit 20 and adjusts at least one of tapping conditions selected from a rotational direction and a rotational speed of the spindle 22 of the drill unit 20 and a combination thereof .

For example, the drill unit 20 includes an electric motor (not shown), the spindle 22 is connected to the electric motor, and the spindle 22 receives electric energy as power received from the outside, . The tool 10 may include a drill bit and a tapping bit. The tapping operation unit 270 includes a jog switch 272 and a jog switch 272 receiving the tapping condition from the operator and a drill unit 272 electrically connected to the electric motor and receiving the tapping condition through the jog switch 272. [ And a control unit (not shown) for controlling the operation of the electric motor of the electric motor 20. The operator can adjust the tapping condition only by a simple operation of the jog switch 272.

More specifically, the tapping operation unit 270 may include a jog switch 272 installed to move back and forth or back and forth, right and left, to the control unit, the jog box 274, and the jog box 274. [ The jog switch 272 may include a lever (not shown) and an electrical signal generator (not shown). The lever has one end and the other end, and the operator can tilt the end in any direction including up, down, left, and right. The electric signal generating unit may be disposed adjacent to the other end of the lever and generate an electric signal through the other end of the lever moving according to the movement of the one end of the lever. The control unit may be disposed inside the jog box 274.

The electrical signal generator may include a variable resistor connected to the other end of the lever and providing different resistance values according to the movement of the other end of the lever. The electric signal generating unit may generate the electric signal through a variable resistance method using a change in resistance value of the variable resistor connected to the other end of the lever moving according to an operation of the lever by an operator. For example, in the case of the variable resistance type, the control unit determines whether the resistance value generated by the electric signal generating unit according to the movement of the lever is larger or smaller than the reference resistance value And recognizes the tapping condition in such a manner that the rotation speed is determined according to the magnitude of the deviation between the reference resistance value and the generated resistance value, and then the rotation speed of the motor of the drill unit 20 The operation can be controlled.

Alternatively, the electrical signal generator may include a plurality of switches disposed adjacent to the other end of the lever. The electric signal generating unit may generate the electric signal through the plurality of switches individually contacting with the other end of the lever in accordance with the movement of the other end of the lever moving according to an operation of the lever by an operator. At this time, a pressure sensor recognizing the pressure according to the degree of movement of the lever may be disposed adjacent to the plurality of switches. In the case of the switch type, the control unit controls the ON / OFF operation of the switch which is in contact with the other end of the lever according to the movement of the lever among the plurality of switches of the electric signal generating unit And recognizes the tapping condition in such a manner that the rotation speed is determined according to the magnitude of the pressure applied to the pressure sensor. Then, the operation of the motor of the drill unit 20 Can be controlled.

Alternatively, the electric signal generating unit may include a variable capacitor connected to the other end of the lever and providing different capacitances according to the movement of the other end of the lever. The electric signal generating unit may generate the electric signal through a variable capacitance method using a change in the capacitance value of the variable capacitor connected to the other end of the lever that moves according to an operation of the lever by an operator. For example, in the case of the variable capacitance type, the control unit determines that the electrostatic capacity value generated by the electric signal generating unit according to the movement of the lever is smaller than the reference electrostatic capacity Recognizes the tapping condition by a method of determining the rotation speed according to the magnitude of the deviation between the reference capacitance value and the generated capacitance value, The operation of the electric motor of the unit 20 can be controlled.

The drill unit 20 is mounted on the tool adapter 100 through the drill bit rotated by the tool adapter 100 receiving the rotational force from the spindle 22 after the drill bit is mounted on the tool adapter 100, The drilling operation can be performed at the machining position. After the drilling operation is performed, the drill bit mounted on the tool adapter 100 is separated from the tool adapter 100 by the operator, and the tapping bit can be mounted on the tool adapter 100 by the operator. Then, the tapping operation unit 270 can perform the tapping operation to the machining position of the workpiece, on which the drilling operation has been performed, according to the tapping condition input from the operator through the jog switch 272. [ Whereby the drilling device 200 using the tool adapter disclosed herein provides a technique by which the drilling operation and the tapping operation can proceed simultaneously through the tool adapter 100. [ The above example is an example for understanding, and various operations may be performed simultaneously through the tool adapter 100 depending on the type of the tool 10 disposed in the tool adapter 100. [

On the other hand, the tapping operation unit 170 may be configured so that operation is controlled when a torque over a reference is generated through a torque limiter or a torque sensor in a tapping process.

In one example, the tapping bits used for the tapping operation may be a structure including a torque limiter. A torque limiter is a torque limiter designed to slip or fall off a joint that transmits torque when the load is above a threshold, and is also referred to as a torque releaser. In other words, the tapping bit is provided between an insertion portion (not shown) to be mounted on the tool adapter 100, a threaded portion (not shown) formed with a thread, and a threaded portion disposed between the insertion portion and the threaded portion, And a torque limiter connected to the threaded portion. When the torque limiter is operated when the tapping bit is excessively caught in the course of tapping operation by receiving the rotational force of the spindle 22 from the tool adapter 100, The breakage of the motor can be prevented. Excessive torque generated during the tapping process can occur in tapping operations on abnormally machined drilled surfaces, tapping operations on the ends of drilled surfaces, and the like.

As another example, a torque sensor (not shown) may be disposed on the rotary shaft (not shown) or the spindle 22 of the motor of the drill 20. In this case, a torque sensor of strain gaitness using a strain gauge attached to the outer surface of the spindle 22 or the rotary shaft of the electric motor as the torque sensor may be used as an example. The torque sensor of the strain gauges can sense the torque from the change of the electrical characteristic such as the resistance change measured from the strain gauge according to the torque generation. Alternatively, as the torque sensor, a plurality of patterns formed at positions spaced apart from each other on the rotation axis (not shown) of the motor or the outer surface of the spindle 22 of the drill portion 20, a light source And an optical torque sensor using a light receiving portion for receiving reflected light reflected from the plurality of patterns can be used. The optical torque sensor can sense the torque by analyzing the reflected light received by the light receiving unit and detecting the twist angle corresponding to the torque. As an example for the sake of understanding, the above example can be used as a torque sensor in various structures as long as it can sense the torque of the rotation axis of the electric motor of the drill 20 or the spindle 22.

The torque sensor receives the rotational force of the spindle 22 from the tool adapter 100 and controls the torque applied to the rotating shaft of the motor or the spindle 22 of the drill 20, Can be detected. The torque sensed by the torque sensor may be provided to the control unit of the tapping operation unit 270. The control unit of the tapping operation unit 270 may determine whether the magnitude of the torque sensed by the torque sensor is equal to or greater than a threshold value, The operation of the electric motor of the drill unit 20 may be controlled to stop the electric motor or reduce the rotational speed or the rotational force of the electric motor.

When the torque is excessively caught in the tapping operation of the tapping bit by receiving the torque of the spindle 22 from the tool adapter 100, the torque sensor senses the tapping operation, The tapping bit and the breakage of the motor of the drill unit 20 can be prevented by controlling the operation of the motor of the unit 20. Excessive torque generated during the tapping process can occur in tapping operations on abnormally machined drilled surfaces, tapping operations on the ends of drilled surfaces, and the like.

The drilling device 200 according to the present invention can operate stably even if a power failure or the like occurs by using the first adsorption part of the non-electric type, and the weight and volume of the equipment can be drastically reduced, Provides the effect of moving equipment.

In addition, the drilling apparatus 200 according to the present invention uses the second adsorption unit having a smaller adsorption power than the first adsorption unit, so that the operator can easily adjust the processing position of the workpiece.

Further, in the drilling apparatus 200 according to the present invention, by using the guide portion, the operator can easily move the drill portion to the processing position of the workpiece.

In addition, the drilling apparatus 200 according to the present technology can provide the effect of simultaneously performing the drilling operation and the tapping operation by including the tapping operation portion.
