Description

Drilling Machine for Furniture Wood {DRILLING MACHINE OF TIMBER FOR FURNITURE}

The present invention relates to a drilling machine, and to a drilling machine for furniture wood for automatically processing holes in the furniture wood.

BACKGROUND OF THE INVENTION In general, a wood drilling machine for processing holes in furniture wood is a device for opening a hole for inserting a hinge, a long handle handle, or a pin for supporting a shelf in a plate-like wood.

When the feeder feeds the plate-like wood in a horizontal state, such a drilling machine opens a hole for the hinge or the handle for installing the above-mentioned handle on the wood.

Such openings are composed of a plurality of horizontally moved motors and a rotating shaft of the motors, the chucks on which opening drills are chucked, and when the motors are driven, the drills interlock to rotate holes, thereby opening holes in wood.

At this time, in order to open the two holes close to each other on the wood, the two motors should be brought into close contact with each other, overlapped, and then be opened.

Then, since the chucks mounted on the motor are in close contact with each other due to the close contact of the motors, the drills are also in close contact with each other. Due to the close contact of the drills, two holes close to each other are processed at once on the wood.

However, in such a general furniture wood drilling machine, since the width of the motor is usually formed from 128mm to 160mm, even if two motors are overlapped to process holes, two holes to be opened in the wood spaced from 128mm to 160mm Has

Therefore, to open two holes on the wood with a distance of 128 mm or less, open the hole at a predetermined position with one motor, move the motor to a distance of 128 mm or less based on this hole, and then open again. Should be carried out.

Only then can two holes with a distance of 128 mm or less be processed on the wood.

On the other hand, furniture wood frequently requires holes spaced at a distance of 88mm to 98mm due to the structural and structural characteristics of the furniture.

In more detail, in the case of the Jangong, in order to fasten the upper and lower ends of the vertically installed handles to the doors of the Jangnon, two holes vertically spaced from the wood for the door are required. The hole requires a separation distance of 88mm to 160mm due to the change of various shapes of the handle.

That is, as the shape of the handle is changed in various ways, the distance between the upper and lower ends of the handle also varies, so the door timber should be formed with a hole for fixing the handle corresponding to this separation distance.

However, in the general drilling machine as described above, two holes having a separation distance of 128 mm to 160 mm can be processed at one time, but holes having a separation distance of less than one cannot be processed at once.

Therefore, to form a hole having a separation distance of 128 mm or less, as described above, after forming one hole, the motor must be moved to form another hole again.

Of course, when the hole is processed by moving the motor each time, there is a problem that the production time of the furniture is extended and productivity is lowered.

Here, only the hole for the handle has been exemplarily described, but in order to manufacture furniture, a lot of holes other than this having a separation distance of 128 mm or less are required.

The present invention has been made to solve the conventional problems as described above, the object is to provide a drilling machine for furniture wood that can process two holes at a time having a separation distance of less than 128mm in the furniture wood at a time.

It is provided integrally and lifts the motors 34 and 64 while extending when opening the drills 36a and 66a.

Then, the drills 36a and 66a are brought into close contact with the wood 100 by lifting up and down the motors 34 and 64, and at the same time, they are opened.

Drilling machine for furniture wood according to the present invention configured as described above, in order to process the hole in the wood 100, first, the operator wants the upper and lower open air (30, 60) on the upper and lower transfer bed (20, 40) It must be fixed in position.

Of course, the fixing position of the upper and lower openings (30, 60) should be the same as the opening position on the wood (100).

Then, when the worker horizontally plated wood 100 is inserted into the feeder 10 as shown in Figure 1, the feeder 10 rotates the roller 12 and the rubber belt, this wood 100 is supplied to the inside of the frame 1.

Subsequently, when the wood 100 is supplied, the upper portion of the wood 100 is pressed by the press 50 of the upper transfer bed 40.

Here, the press 50 presses the timber 100 by the press plate 58 descending by the extension of the pressurized cylinder 56, and the timber 100 is pressurized directly to the press plate 58.

Then, the wood 100 is firmly fixed to the roller 12 of the feeder 10 due to the press of the press 50. When the wood 100 is fixed in this way, the upper and lower open air 30 and 60 are wood. Open the hole at (100).

Of course, the upper and lower open air (30, 60) can move the motor 34, 64 to the timber 100 as the lifting cylinder 38 is stretched, the drill by the proximity of the motor (34, 64) 36a and 66a are in close contact with the surface of the wood 100.

As such, when the drills 36a and 66a are in close contact with the surface of the wood 100, the motors 34 and 64 are driven so that the drills 36a and 66a open the wood 100.

At this time, the upper and lower open air (30, 60) the lifting cylinder 38 continues to push the motor (34, 64) a little bit toward the wood 100 side, thereby drilling (36a, 66a) the wood at the same time as the opening It is inserted into the interior of 100 so that it eventually penetrates the wood 100.

Therefore, a hole is formed in the wood 100 at a desired position. After the hole is formed, the upper and lower open air 30 and 60 and the press 50 are restored to their original positions, and then the wood 100 having the hole is formed. When it is separated from the frame 1, the opening work of the wood 100 is completed.

Meanwhile, as shown in FIG. 1, when two motors 34 and 64 overlap each other in parallel, the wood 100 has a separation distance equal to the width W of the motors 34 and 64 as shown in FIG. 2. A hole having is formed.

This is because, when the motors 34 and 64 are in close contact with each other, the rotation axis of the motors 34 and 64 is located at the center of the motors 34 and 64, so that the radius of the motors 34 and 64 as shown in FIG. r), and when the two rotary shafts gather together as the motors 34 and 64 overlap, the rotary shafts are spaced equally to the diameter R of the motors 34 and 64, so that the motors 34 and 64 It is spaced at the same distance as the width (W) of.

Accordingly, the drills 36a and 66a standing up on the coaxial line with the rotation shafts of the motors 34 and 64 are also spaced apart by the same distance as the width W of the motors 34 and 64.

Therefore, the separation distance between the holes spaced from each other in the wood 100 is determined to be 88mm to 98mm equal to the width (W) of the motor (34, 64).

Here, in order to set the separation distance between the holes formed in the wood 100 to be 98 mm or more, the two motors 34 and 64 may be spaced apart from each other.

On the contrary, when the separation distance between the holes of the wood 100 is 88 mm or less, the upper and lower openings 30 and 60 are operated to open one hole on the wood 100 first, and then The lower openings 30 and 60 should be moved to 88mm or less based on the openings, and then open again.

However, since the furniture timber 100 does not require a hole having a separation distance of 88 mm or less, the furniture timber drilling machine according to the present invention can process most furniture timber 100 without any inconvenience.

In conclusion, the drilling machine for furniture wood according to the present invention as described above, it is possible to form a hole in the wood 100 at a time having a separation distance of 88mm to 98mm that was not possible in the prior art.

Conversely, the present invention can produce a wood 100 formed with a hole having a separation distance of 88mm to 98mm.

On the other hand, in the above description of the present invention has been illustrated an example of applying only the furniture wood 100 to the present invention, otherwise, the present invention can be applied to architectural or kitchen wood.

That is, the present invention is not only applied to the processing of furniture wood 100, but may be applied to the processing of all wood.

The above-described embodiments are merely illustrative of the preferred embodiments of the present invention, and the scope of application of the present invention is not limited thereto, and may be appropriately changed within the scope of the same idea.

Therefore, the shape and structure of each component shown in the embodiment of the present invention can be carried out by modifying, it is natural that the modification of the shape and structure belong to the utility model registration claims of the present invention attached.
