Description

Technical Field

[0001] The invention relates to the technical field of wood hole drilling, in particular to a wood hole drilling device for a table. Background Art

[0002] Tables are a kind of furniture commonly used in our lives. Tables usually include accessories such as table tops and table legs. Some table legs are equipped with pulleys at the bottom for easy movement. It is necessary to drill holes at the bottom of the table legs to install the pulleys. During the installation process, the stress of the table legs changes, and there is a risk of cracking of the table legs. At this time, it is necessary to add concave wooden blocks to the bottom of the table legs to effectively reduce the risk of cracking of the table legs and ensure the smooth progress of the installation process. In the production process of concave wooden blocks, multiple surfaces need to be punched for easy installation. However, when performing batch punching, it is not easy to clamp the concave wooden blocks due to their different states during the loading process. It is difficult to position the material and it is not easy to cut the material, which affects the work efficiency. When drilling, it is necessary to position and drill multiple surfaces in sequence, which leads to problems such as reduced drilling accuracy and hole position deviation. When the concave wood block is clamped externally, marks are left on the surface of the object or minor damage is caused, which affects the appearance of the product and requires later repair of the scars, thereby increasing the cost of wood processing. When clamping externally, it is easy to block the hole position, affecting the drilling progress. The debris generated during drilling floats on the work surface, which increases the difficulty of cleaning. For this reason, we propose a wood hole opening device for a table.

[0016] 2. The present invention proposes a wood hole-opening device for a table, wherein a turntable intermittently rotates, and a concave wood block slides down along an inclined guide pipe and enters a first through hole. The concave wood block with the hole inclined upward enters the bottom of the guide pipe along the first through hole obliquely above, the second through hole and the first through hole obliquely below. When the opening of the concave wood block is inclined downward, the concave wood block is stuck on the block due to gravity, and slides out from the bottom through the rotation of the turntable and enters the guide pipe, so that the concave wood block maintains a correct alignment during the production process, and the hole is always facing upward, which can minimize the number of parts replacements, thereby saving time and cost, and making it easier for the positioning rod to be embedded in the interior of the concave wood block to clamp and position it.

[0018] 4. The present invention proposes a wood hole-punching device for a table.

The debris can be effectively collected while drilling, avoiding the problems of extended cleaning time and reduced work efficiency caused by flying debris in traditional methods, reducing the time and physical exertion of manual cleaning, and improving the safety factor of the operation.

[0019] 5. The present invention proposes a wood hole-punching device for a table, which drives multiple positioning rods at the bottom to move up and down through a lifting frame, and at the same time, the concave wooden blocks are picked up and put down through the positioning rods. The rotating frame drives the punched concave wooden block to rotate to the other side of the partition, and is transported out from the discharge port through a conveyor belt. At this time, the next concave wooden block can continue to be positioned. The arranged partition can prevent the unpunched concave wooden block from moving out of the device, and at the same time, the punched concave wooden block and the punched concave wooden block can be well distinguished, thereby improving space utilization, realizing fast loading and unloading, and significantly improving production efficiency, avoiding time delays and inefficiency problems in operation.
