Description

Technical Field

[0001] The utility model relates to the technical field of drilling machines, and more particularly to a drilling machine for wood fiberboards. Background Art

[0002] Fiberboard refers to an artificial board formed by interweaving wood cellulose fibers and made using its inherent adhesive properties. Adhesives and / or additives can be applied during the manufacturing process. Fiberboard, also known as density board, is an artificial board made from wood fibers or other plant cellulose fibers with urea-formaldehyde resin or other suitable adhesives applied.

[0003] Fiberboard is usually composed of granular or powdery plant fibers. From its structure, it can be seen that the internal connection strength is not stable and it is easy to break in all directions. When drilling, at the end of the drill hole, the fiberboard is easily impacted by the drill bit and a large number of fragments are easily generated at the edge of the end of the drill hole. When the fragments fall off, pits of different sizes will be formed at the drill hole, which to a certain extent affects the aesthetics of the drill hole and is not conducive to subsequent installation of bolts, etc. Therefore, a more reasonable fiberboard drilling device needs to be designed. Summary of the Utility Model

[0004] The purpose of the utility model is to provide a drilling machine for wood fiberboards, which can effectively ensure that no fragments appear at the end of the drill hole of the fiberboard during drilling, making the drill hole more complete.

[0023] Embodiment

[0024] The following is further described in conjunction with specific embodiments. As shown in the attached Figure 1 - attached Figure 4 As shown in the figure, the drilling machine for wood fiberboard in this embodiment includes a bottom plate 11, an operating table 12 provided on the bottom plate 11, a through hole 13 opened on the operating table 12, a slide rail 14 vertically provided on the bottom plate 11, a first electric drill 21 provided above the operating table 12 and facing downwards, a first bracket 22 connected to the first electric drill 21, a second electric drill 31 provided below the operating table 12 and facing upwards, a second bracket 32 connected to the second electric drill 31, a first driving device for driving the first bracket 22 to lift, and a second driving device for driving the second bracket 32 to lift; the first electric drill 21 and the second electric drill 31 are coaxially arranged; both the first bracket 22 and the second bracket 32 are slidably connected to the slide rail 14. Specifically, when in use, a thick fiberboard is placed on the operating table 12, and the part to be drilled is placed directly below the drill bit of the first electric drill 21. When drilling, the first driving device is used to drive the first bracket 22 and the first electric drill 21 to move downwards to drill the fiberboard. During this process, the second driving device drives the second bracket 32 and the second electric drill 31 to move upwards to drill the lower side of the same position of the fiberboard. The second electric drill 31 only needs to drill into the fiberboard about 5 mm in thickness and then move down to the previous position. Then the first electric drill 21 continues to drill through the hole on the fiberboard. In this way, by drilling the lower side of the drilling position in advance with the second electric drill 31, it can be ensured that when the first electric drill 21 drills through the hole, no debris will fall off at the lower edge of the perforation, and the drilled hole can be kept as complete as possible, making the drilling more beautiful.

[0025] The first driving device in this embodiment includes a first sliding plate 23 slidably disposed in the slide rail 14, a first rack 24 vertically disposed on the first sliding plate 23, a first gear 25 meshing with the first rack 24, and a motor 26 connected to the first gear 25. By driving the first gear 25 to rotate with the motor 26, the first rack 24 is driven to move in the vertical direction, thereby achieving the purpose of driving the first sliding plate 23, the first bracket 22, and the first electric drill 21 to move up and down. For the cooperation between the first gear 25 and the first rack 24, it can also be replaced with the cooperation between a rack and a worm, thereby achieving the purpose of self-locking. A hand crank for manual rotation can also be provided on the first gear 25.

[0026] The second driving device in this embodiment includes a second sliding plate 33 slidably disposed in the slide rail 14, a connecting plate 34 provided at the upper end of the second sliding plate 33, a driving rod 35 hinged to the connecting plate 34, a second gear 37 provided above the connecting plate 34, a turntable 36 connected to the side of the second gear 37, and a driving assembly for driving the second gear 37 to rotate; the driving rod 35 is hinged to a position near the edge of the turntable 36; the second gear 37 is rotatably connected to the slide rail 14 through a rotating shaft 38. Specifically, since the drilling depth of the first electric drill 21 is relatively shallow, it only needs to move up and down within a small range. Therefore, by driving the second gear 37 to rotate with the driving assembly, the turntable 36 drives the driving rod 35 to pull the connecting plate 34 and the second sliding plate 33 to move up and down slightly.

[0027] The driving assembly in this embodiment includes a driving bar 27 vertically connected to the lower end of the first sliding plate 23, and a second rack 28 provided on the side of the driving bar 27; the second rack 28 is provided above the side of the second gear 37. Specifically, when the first electric drill 21, the first bracket 22, the first sliding plate 23, the driving bar 27, and the second rack 28 descend to a certain position, the second rack 28 meshes with the second gear 37. When the second rack 28 continues to descend, it can drive the second gear 37 to rotate. The length of the second rack 28 can only drive the second gear 37 to rotate one circle. When the second gear 37 continues to move downward, the second rack 28 disengages from the second gear 37, and at this time, the second gear 37 cannot continue to rotate, which can avoid the situation where the first electric drill 21 collides with the second electric drill 31. When the drilling is completed and the first electric drill 21 moves upward, the second rack 28 will also move upward, and then drive the second gear 37 to rotate one circle again, causing the second electric drill 31 to move upward again, which can clean the burrs on the lower edge of the drilling to a certain extent and make the end of the drilling more beautiful.

[0028] At the upper end of the slide rail 14 in this embodiment, there is a top plate 17, and a first spring 15 is provided between the top plate 17 and the first bracket 22. A second spring 6 is provided on the upper side of the bottom plate 11, and the upper end of the second spring 6 is connected to the second bracket 32. Specifically, the first spring 15 and the second spring 6 are mainly used for supporting the first electric drill 21 and the second electric drill 31.

[0029] In summary, for the drilling machine for wood fiberboard in this embodiment, when in use, place the thick fiberboard on the operating table 12, and place the part to be drilled directly below the drill bit of the first electric drill 21. When drilling, use the first driving device to drive the first bracket 22 and the first electric drill 21 to move downward to drill the fiberboard. During this process, the second driving device drives the second bracket 32 and the second electric drill 31 to move upward to drill the lower side of the same position of the fiberboard. The second electric drill 31 only needs to drill about 5 mm into the fiberboard and then move downward back to the previous position, and then the first electric drill 21 continues to drill through the hole in the fiberboard. In this way, by drilling the lower side of the drilling position in advance with the second electric drill 31, it can be ensured that when the first electric drill 21 drills through the hole, there will be no situation such as debris falling off at the lower edge of the perforation, and the drilling can be kept as complete as possible, making the drilling more beautiful.

[0030] The above are only the preferred embodiments of the present invention and are not used to limit the present invention. For those skilled in the art, various changes and modifications can be made to the present invention. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
