In general, a tabletop drilling machine or a tapping chuck of a milling machine is a device capable of drilling a hole in a workpiece or forming a tab or the like by rotating and rotating a cutting tool such as a drill on a rotating rotary shaft. Such a drill machine has a workpiece placed on a workbench, a drill is mounted on the rotary chuck, and a rotary motor is rotated while a rotary chuck is moved up and down by a lever so that a hole can be drilled in the workpiece.

In this case, the worker holds the workpiece with one hand while pulling the lever with the other hand to perform the boring operation. When the glove to be worn by the worker to protect the hand rotates with the chip generated by the rotation of the drill Occasional accidents that often damage the operator's hand have occurred. Also, in the process of drilling a hole in the workpiece, an accident occurred in which the chip jumped to the operator's eyes.

Such a problem could be somewhat solved by the safety protection cover disclosed in Korean Patent No. 10-0985788 (published on Oct. 06, 2010).

That is, as shown in FIG. 1, an inner cylinder 200 of a transparent tube, which is mounted and fixed by a fixing band 210 at a lower end of a projecting and retreating shaft of the head to allow a rotary shaft of a tabletop drill to be inserted therein, A transparent tube outer body 300 slidably coupled to the outside of the outer cylinder 300 and having a guide hole 310 formed in a vertical length direction on both sides of the outer circumference thereof and a female threaded portion formed on a lower inner circumferential surface thereof, The inner cylinder 200 and the outer cylinder 300 are connected to the inner cylinder 200 through the guide holes 310 of the outer cylinder 300 by the fixing bolts 500 The drill is not exposed to the outside, so that the safety of the worker can be prevented in advance.

However, such a safety cover has a problem in that the structure is complicated because the safety cover is fixed to the projecting and retreating shaft of the drill machine while the inner cylinder and the outer cylinder are slidably engaged.

Particularly, when the drill is exchanged, it is inconvenient to remove it from the projecting shaft.

In addition, a chip generated due to the rotation of the drill rotates inside the outer cylinder to generate scratches on the inner circumferential surface of the outer cylinder, so that the transparency of the outer cylinder is lowered and the inside of the outer cylinder can not be seen from the outside during drilling It was. In the case where it is difficult to ensure the visibility of the outer body, it is necessary to replace the outer body as a whole, thereby increasing the replacement cost and complicating the replacement structure.

The attachment means (30) is composed of a polygonal structure or a flexible structure so that the middle portion is bent or warped and the bending or warpage is fixed or controlled. And the other end is connected to the attaching means 30 and a connection member 40 which is not scattered in the rotational direction of the drill 14 so as to prevent the chips generated during the drilling operation from interfering with the inside of the protective tube 20, And a chip lift preventing member 70 is provided on the lower surface of the protective tube (20).

This will be described in more detail as follows.

The tapping chuck 10, the socket 12 and the drill 14 of the drill machine are already well known and will not be described in detail.

The protective tube 20 is formed of a transparent synthetic resin material or a glass material and has a polygonal or cylindrical flat cross-sectional shape. The tapping chuck 10 of the drill machine, the socket 12, Lt; RTI ID = 0.0 > and / or < / RTI > The protective tube 20 is not limited to an integral transparent tube structure, but may be constructed of a transparent tube having various structures or a structure divided into an opaque region and a transparent region, and may be made of tempered glass.

The attaching means 30 is detachably attached to the body of the drilling machine or a machine disposed in the periphery of the drilling machine. In this embodiment, the attaching means 30 will be described based on a structure that is attached to a metallic surface by a magnetic force. That is, the attaching means 30 according to the present embodiment is constituted by a magnet attaching device. The attaching means 30 has an on / off function and generates or extinguishes a magnetic force by the operation of the magnet switch 32 . Therefore, the user can operate the magnet switch 32 to attach the attachment means 30 to the metal body or to separate the attachment means 30 attached to the metal body.

The reason why the attachment means 30 is formed of a magnet attaching device is that the removal and attachment can be performed quickly and easily, and a strong magnetic force is generated and the protection tube 20 can be easily supported.

Of course, the attachment means 30 may be composed of a clamp, a bolt, or the like.

The connecting member 40 is used to freely adjust the position and the installation angle of the protective tube 20 by connecting the attachment means 30 and the protective tube 20 and to fix the adjusted position and the installation angle, Bent and bent, and bent or warped is fixed or adjusted so that one end is coupled to the outer surface of the protective tube 20, and the other end is coupled to the attachment means 30. [

The connecting member 40 may be a multi-jointed structure. For example, the connecting member 40 may include a first rod 44A, one end of which is coupled to the attachment means 30 as shown in FIG. 2, And the other end of the first rod 44A and the second rod 44B are inserted in different directions and engaged with each other so that the first rod 44A or the second rod 44B, 44B having a fastening member 44C for tightening the other end of the first and second fasteners 44A, 44B.

The connecting member 40 having such a structure is determined by adjusting the position and angle of the protective tube 20 by moving the first rod 44A and the second rod 44B fitted to the connecting rod 44D, (44C) to fix the adjusted condition.

At this time, one end of the second rod 44B may be fixed to the fixed plate fixed by screwing or riveting to the protective tube 20 by welding or the like, may be directly coupled to the protective tube 20, Both the attachment plates can be fixed to the outer circumferential surface of the protective tube 20 by screwing or riveting and the one end of the second rod 44B can be welded to the hinge shaft connecting the attachment plates.

5A, the connecting member 40 according to another embodiment includes a plurality of joints 46A for connecting multiple rods 46 so that multiple rods 46 can be folded, One end of the rod 46 may be configured to be coupled to the attachment means 30 with a ball joint 46B. Since the connecting member 40 having such a structure is composed of a plurality of rods 46, joints 46A, and a ball joint 46B, it is possible to freely adjust and fix the position of the protective tube 20.

In addition, as shown in FIG. 5B, the connecting member 40 according to another embodiment may be formed of a flexible pipe 48 having a plurality of ball joint connectors so as to be free from bending or bending. This flexible pipe 48 is also coupled to the attachment means 30 by a ball joint.

It is a matter of course that not only the connecting member 40 of each of the above-described embodiments but also various connecting members of a multi-joint structure can be applied.

As shown in FIGS. 2 and 3, the chip-rise preventing member 70 interferes with chips generated during a drilling operation so as to prevent the chips from flowing into the protective tube 20, So that the drill 14 does not interfere with the rotation of the drill 14 and the upward or downward movement of the drill 14 when the drill 14 rotates and moves upward and downward, And is coupled to the bottom surface of the protective tubular body 20 with the penetrating drill actuating part 72.

The chip rising preventing member 70 according to the present embodiment is formed in a plate shape made of a rectangular metallic material or a synthetic resin material having a predetermined width. One end is bent upward to be coupled to the outer circumferential surface or the inner circumferential surface of the protection tube 20 and is formed with a fixed end 74 and the other end is cut on both sides to form the drill operating portion 72, And are bent downward as shown in FIGS. 2 and 3, respectively, so that a plurality of chip interference ends 76 are formed. The chip interfering stages 76 are bent downward as shown in FIG. 3, so that the chip rising due to the rotation of the drill 14 interferes with the chip interfering stage 76 and falls without falling. That is, since each chip interference stage 76 is bent downward while forming the drill operation part 72 in which the drill 14 is operated, the chips that are raised by the rotation of the drill 14 are moved to the chip interference stages 76 So that it can fall downward.

As shown in Fig. 2, the chip up-and-up preventing members 70 may be arranged at two positions opposed to each other with the drill operating part 72 as a center, and three or more, Four drills can be radially arranged around the drill actuating part 72, respectively.

That is, as shown in FIG. 2, the protective chip 20 is formed so that the two chip-rise preventing members 70 are symmetrically arranged to form the drill actuating part 72 by the chip interfering stages 76 therebetween. Three or four chip rising preventing members 70 may be radially arranged so that the chip interfering ends 76 at the centers of the respective chip rising preventing members 70 are engaged with the drill So that the operating portion 72 can be formed.

Since the chip up-and-coming member 70 has a predetermined width (approximately 1 to 3 cm), it does not obstruct the view of the operator during the drilling operation.

Meanwhile, in the accompanying drawings, Figs. 4A, 4B and 4C are schematic exploded perspective views showing other embodiments of the chip up-stop preventing member shown in Fig.

As shown in FIG. 4A, the chip up-and-up preventing member 70 according to another embodiment is formed of a disk-like plate made of a thin metal or a synthetic resin, the drill operating portion 72 is formed at the center thereof, The chip 72 has a structure in which a plurality of chip interference ends 76 are protruded or bent. At this time, it is preferable that the chip rising preventing member 70 according to another embodiment is made of a transparent material. It is a matter of course that the fixed end 74 to be coupled to the protective tube 20 is protruded upward from the edge.

As shown in FIG. 4B, the chip up-and-up preventing member 70 according to another embodiment is formed in a plate shape made of a metal material or a synthetic resin material, a drill operating portion 72 is formed at the center thereof, A plurality of chip interference ends 76 are protruded or bent downward on the bottom surface of the portion 72. Three support ends 78 are formed at an angle of 120 degrees around the drill actuating part 72 so that the ends of the support ends 78 are engaged with the outer circumferential surface or the inner circumferential surface of the protective tube 20. [ And has a structure in which the fixed end 74 is formed by being bent upward or downward.

As shown in FIG. 4C, the chip-rising preventing member 70 according to another embodiment is formed in a plate shape of a rectangular metallic material or a synthetic resin material having a predetermined width, A drill operating portion 72 is formed at the center and a plurality of chip interfering stages 76 are formed on the bottom surface of the drill actuating portion 72, Protruded or bent. That is, the chip up-and-up preventing member 70 according to another embodiment has the integral type structure of the "┃" type, penetrates through the drill actuating part 72, and the chip interference end 76 is formed on the bottom face. The chip up-and-coming-preventing member 70 having such a structure can be easily installed and removed by being integrally formed.

The operation of the safety device for the drill machine having the view field securing and chip scattering prevention structure according to the present invention constructed as described above will be described.

As shown in FIGS. 2 and 3, the attachment means 30 is attached to the body of the drill machine or fixed to the body of another apparatus in close proximity, and then the protective body 20 made of a transparent material is moved to the drilling operation position . At this time, the protective tube 20 is connected to the attaching means 30 by the connecting member 40. Since the connecting member 40 is composed of multiple joints, the position and the installation angle can be arbitrarily adjusted. Then, when the position is determined, the position and angle of the protective tube 20 are fixed by operating the connecting member 40.

That is, the protective tube 20 is moved upward from the bottom so that the tapping chuck 10 and the drill 14 are inserted into the protective tube 20, and then the tapping chuck 10 is inserted into the protective tube 20, The position of the protective tubular body 20 is fixed by operating the connecting member 40.

In this process, the tapping chuck 10, the socket 12 and the drill 14 are positioned in the inner space formed by the protective tube 20, so that they are not exposed to the outside.

At this time, it is a matter of course to determine the position of the protective tube 20 so that the drill 14 passes through the drill operating portion 72.

In this state, when the drilling operation is performed, a chip is generated in the process of drilling the base material by the drill 14.

The chips generated by the drilling operation are made in the inside or the bottom area of the protection tube 20, so that it is possible to prevent a safety accident that the chip splashes on the operator's face or touches the operator's hand. Further, since the protective tube 20 is made of a transparent material, the operator can watch the work space without restriction.

On the other hand, the chip generated by the drilling operation moves upward while rotating like the drill 14, but the tip of the chip rising preventing member 70 installed across the bottom surface of the protective tube 20 It is interfered with the chip interfering stage 76 to prevent the chip from rising upwardly and eventually interfering with the chip rising preventing member 70 itself and not moving upward.

That is, since the chip rotating like the drill 14 hits the chip interferometer stage 76 and the chip lift-up prevention member 70, it can not move upward but falls downward.

Therefore, it is possible to prevent the phenomenon that the degree of transparency of the protective tube 20 is lowered by scratching the inner peripheral surface of the protective tube 20 by the chip raised by the drilling.

6A and 6B are schematic cross-sectional views showing that the protective tube shown in FIG. 2 is provided with illumination means.

As shown in Figs. 6A and 6B, the protection tube 20 may be provided with an illumination means 60. Fig. 6A and 6B, the outer peripheral surface of the lower end of the protective tube 20 or the lower end thereof is provided with the illumination means 60 for irradiating light at the drilling position in the drilling operation, .

The lighting means 60 includes a power supply 62 provided on the attachment region 30 or the coupling region of the protection tube 20 and the connection member 40 or the outer peripheral surface of the protection tube 20, An on / off switch 64 provided on the power supply 62, and an LED lamp 66 which is emitted by a power source supplied from the power supply 62.

At this time, the power supply 62 may be composed of a battery included in the case, or may be formed of an electric wire, an AC / DC converter, or the like to receive power from the outside. In the present embodiment, a case is attached to the outer surface of the protective tube 20 and a battery provided inside the case and configured to supply power to the LED lamp 66 by the operation of the off switch 64 Explain.

The LED lamp 66 may be replaced by a filament type bulb, but in this case consumes a lot of electric power. Therefore, it is preferable that the LED lamp 66 is composed of an LED element having low power consumption and good durability. As shown in FIG. 6A, the LED lamp 66 may be provided with a cover 61 on the outer circumferential surface of the lower end of the protective tube 20, and may be provided with a plurality of strip- The attachment member 68 may be attached to the lower end surface of the protection tube 20 to be provided in the protection tube 20 in a state where the attachment member 68 is electrically connected to the member 68 and arranged at regular intervals.

Since the illumination means 60 is provided in the lower region of the protective tube 20 in this way, the operator operates the on / off switch 64 during drilling to light the LED lamp 66, thereby securing illumination at the drilling operation position The accuracy and safety of the work can be expected.

[

That is, the protective tube 20 is in use time due to various factors (cutting oil, oil, dust, chip scratches, etc.), and transparency decreases in proportion to the period of use. However, when replacing the entire protective tube 20 whose transparency is lowered, an economic loss occurs, and replacement work is also difficult. Therefore, the opening 22 is formed in a part of the protective tube 20 (the position where the operator can see through the drilling space), and the transparent plate 90 is replaceably installed in the opening 22. [

At this time, the transmission plate 90 is formed in an arc-shape or a flat plate shape, and the portions where the transparent plates 90 and the opening 22 overlap each other can be fastened with bolts, nuts, or screws.

However, in this case, there is an inconvenience that bolts or nuts must be tightened to replace the transmission plate 90. To overcome this, there is a fitting groove 92 formed at both ends in the longitudinal direction of the transmission plate 90 (22A, 22B) of the opening (22). In the upper region of each fitting groove 92, when the two edges 22A and 22B of the opening 22 are moved downward and fitted, the engaging jaws 22A and 22B for preventing the both edges 22A and 22B from falling downward (94) are formed. That is, the latching jaw 94 is formed on the upper portion of the fitting groove 92, so that the transmission plate 90 is no longer moved downward.

As described above, since the transmission plate 90 is fitted to both edges 22A and 22B of the opening 22, the operation of replacing the transmission plate 90 can be performed quickly and easily.

As described above, the opening 22 is formed in a part of the protective tube 20, and the transparent transparent plate 90 is replaceably provided in the opening 22, so that the transparent plate 90 is contaminated by the user, It is possible to quickly and easily secure the visual field of the drilling work space by separating the penetration plate 90 from the protective tube 20 and mounting the new penetration plate 90 to use it, The cost required for securing the view can be reduced.

9A and 9B are partially enlarged cross-sectional views illustrating a detachable attachment / detachment structure of a transmission / reception plate according to another embodiment shown in FIG. 7 in the accompanying drawings.

9A according to another embodiment of the present invention, the structure for replacing the transmission plate 90 is such that the engagement grooves 22C are formed in both edges of the opening 22 in the longitudinal direction, Is the same as the above-mentioned embodiment,

9B, an iron plate or a magnet 96 is attached to the inner or outer surface of the inner and outer edges 22A and 22B of the opening 22, And an iron plate or a magnet 98 is provided on the inner side or outer side of both sides of the transmission plate 90 corresponding to the iron plate or the magnet 96 so that the transmission plate 90 is rotated by the magnetic force, Except that it is coupled to the < / RTI >

At this time, the magnets 96 and 98 may be installed on the inner or outer surfaces of the two edges 22A and 22B and the inner or outer surfaces of both edges of the transmission plate 90, respectively. If a magnet is installed on either side, an iron plate may be installed on the other side.

As described above, since the magnets 96 and 98 and the magnets and the iron plate are provided in the areas where the openings 22 and the transmissive plate 90 are overlapped with each other, the operation of replacing the transmissive plate 90 can be performed quickly and easily You can.

As described above, since the drill 14 is positioned inside the protective tube 20 made of a transparent material, a safety accident can be prevented in the drilling operation, The provision of the member 70 not only prevents scratching of the protective tube 20 due to the rise of the chip but also prevents chip scattering and prevents the protective tube 20 from being damaged due to scratches or other contamination Even if it is difficult to obtain a working view, it is possible to replace with a new transfer plate 90, so that it is possible to easily secure the visual field of the drilling operation.
