Description

Technical Field

[0001] This utility model relates to the field of drilling technology, and in particular to a drilling device for processing log furniture. Background Technology

[0002] When processing wooden furniture, it is often necessary to drill holes in the wood panels. When drilling larger diameter holes, a cylindrical hole drill is required. This type of hole drill is closed at one end along its axis, and the open end has teeth on its circumference. To prevent drilling waste from remaining inside the drill, a drill bit is installed inside, with its end extending beyond the drill. An elastic element, usually a spring, is fitted onto the drill bit. The drill bit acts as a positioning element, preventing the drill from deviating from its intended path, while the spring ejects the drilled cylinder from the drill. However, when processing harder wood, the spring wears out more quickly, significantly affecting its waste removal efficiency. Furthermore, the material requirements for the drill bit are also higher, and using only the drill bit for positioning does not prevent the drill from tilting. Summary of the Invention

[0003] To address the problems mentioned in the background art, the purpose of this utility model is to provide a drilling device for processing log furniture.

[0004] To achieve the above objectives, the technical solution of this utility model is as follows:

[0005] A drilling device for processing log furniture includes a drill, which is a cylindrical shape sealed at one end. A connector is coaxially arranged on the sealed end of the drill. The open end of the drill has serrations distributed circumferentially. Multiple guide rods are inserted axially inside the sealed end of the drill. One end of the multiple guide rods is fixedly connected to a connecting plate. The other end of the guide rods is detachably connected to an anti-detachment block. The connecting plate can freely enter and exit the inner cavity of the drill. A shaft head is fixedly connected to the side of the connecting plate opposite to the sealed end of the drill. The shaft head is coaxially arranged with the drill. A sleeve is installed on the shaft head through a bearing. A positioning plate is fixedly connected to the end of the sleeve opposite to the connecting plate. The positioning plate is perpendicular to the shaft head. An elastic element is abutted between the sealed end of the drill and the connecting plate. The elastic element drives the anti-detachment block to abut against the sealed end of the drill, and causes the positioning plate to protrude from the outside of the drill.

[0006] Furthermore, the circumferential surface of the punch has a plurality of chip removal holes distributed circumferentially.

[0007] Furthermore, the elastic element is a plurality of compression springs, and the plurality of compression springs are respectively sleeved on the plurality of guide rods.

[0008] Furthermore, several of the guide rods are evenly arranged along the circumference of the punch.

[0009] The beneficial effects of this utility model are as follows: by setting the elastic element between the connecting plate and the closed end of the punch, the elastic element can still play the role of ejecting waste material, while avoiding direct contact between the elastic element and the wood, thus preventing damage to the elastic element; the positioning plate can rotate relative to the punch without wear, which can reduce the material requirements; the positioning plate can correct the verticality of the punch, effectively preventing the punch from tilting and providing an anti-deviation effect.

[0013] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model are within the protection scope of the present utility model.

[0014] like Figures 1-2As shown, a drilling device for processing log furniture includes a drill 1, which is a cylindrical shape with a closed top. A connector 11 is coaxially mounted on the top of the drill 1 for connecting to the output end of a handheld electric drill. The bottom edge of the drill 1 has serrations 12 distributed circumferentially. Two guide rods 2 are longitudinally inserted inside the closed end of the drill 1. A connecting plate 21 is fixedly connected to the bottom ends of the two guide rods 2. Anti-detachment blocks 3 are detachably connected to the top ends of the guide rods 2. Preferably, the top ends of the guide rods 2 have threaded portions, and the anti-detachment blocks 3 are nuts, threadedly connected to the drill. At the top of the punch 1, under the action of the guide rod 2, the connecting plate 21 can slide freely in or out of the punch 1 longitudinally. The bottom of the connecting plate 21 is fixedly connected to the shaft head 22, which is coaxially arranged with the punch 1. A sleeve 51 is installed on the shaft head 22 through the bearing 4. The bottom end of the sleeve 51 is fixedly connected to the positioning plate 5, which is circular and perpendicular to the shaft head 22. An elastic element 6 is provided between the closed end of the punch 1 and the connecting plate 21. The elastic element 6 drives the anti-detachment block 3 to abut against the closed end of the punch 1, and makes the positioning plate 5 protrude from the outside of the punch 1.

[0015] In actual use, the punch 1 is first installed on a handheld electric drill via connector 11. When drilling holes in a wooden board, the positioning plate 5 is placed against the board to ensure the perpendicularity of the punch 1 to the template, thus preventing the punch 1 from tilting. After drilling is completed, the elastic element 6 is reset, which pushes the wooden post left in the punch 1 outward, thereby popping the wooden post out and removing waste. Compared with the traditional cylindrical punch 1, the elastic element 6 is set between the connecting plate 21 and the closed end of the punch 1, and will not come into direct contact with the wood, which can effectively prevent wear of the elastic element 6. In addition, the positioning plate 5 can rotate relative to the punch 1, and there is no risk of wear, which can reduce the material requirements of the positioning plate 5.

[0016] In this embodiment, the circumferential surface of the punch 1 is provided with a plurality of chip removal holes 13, which facilitate the removal of waste chips during the punching process.

[0017] In this embodiment, the elastic element 6 consists of two compression springs, which are respectively sleeved on the two guide rods 2. Compression springs are readily available, and sleeved on the guide rods 2 can also prevent the springs from falling off.

[0018] In this embodiment, the two guide rods 2 are evenly arranged along the circumference of the punch 1. The design is reasonable and ensures that the center of mass of the punch 1 is on its own main axis, thus avoiding imbalance when the punch 1 rotates.

[0019] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
