Description

Technical Field

[0001] This invention relates to the field of sheet metal drilling technology, specifically to a drilling device for processing office desk sheets. Background Technology

[0002] In the manufacturing of office furniture (such as desks), drilling of the board material is a basic and crucial process. Traditional drilling operations mostly rely on ordinary bench drills or handheld electric drills combined with manual positioning. This method has several obvious drawbacks: First, the processing accuracy is difficult to guarantee. Manual marking and positioning and manual operation are prone to cumulative errors, resulting in inaccurate hole positions, which affects the subsequent assembly quality and efficiency. Second, the degree of automation is low and the labor intensity is high. For boards that need to be drilled with multiple holes, workers need to repeatedly position, clamp, and drill, resulting in low production efficiency.

[0003] Drilling wood generates a large amount of fine sawdust and dust. Traditional equipment generally lacks an effective integrated dust removal device or is only equipped with a side-suction dust collection hood with limited effectiveness. A large amount of dust permeates the processing site, which not only seriously pollutes the working environment and endangers the respiratory health of workers, but also affects the accuracy of equipment and electrical safety in the long run. The cleaning cost is also high. Therefore, a drilling device for processing wood panels for office desks is proposed to solve the above problems. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to provide a drilling device for processing board material for office desks, which addresses the shortcomings of the prior art.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by the present invention is: a drilling device for processing office desk boards, including a processing table, and further comprising: The bracket is fixedly connected to the bottom of the processing table to support it. The plywood is placed on top of the workbench; An adjustment mechanism, set on the processing table, is used to move the drilling mechanism mounted on the adjustment mechanism to drill holes in the plywood; The negative pressure dust removal mechanism is located below the drilling mechanism and is attached to the plywood along with the drilling mechanism to absorb the sawdust generated during drilling. The adjustment mechanism includes: The processing table is arranged in a U-shape, and adjustment holes are provided on the inner wall of the processing table; Multiple sliding rods are fixedly connected to the inner wall of each adjustment hole, and two of them are fixedly connected to the machining table extending backward and to the right respectively; Multiple rodless cylinder sliders are respectively set on the inner wall of each adjustment hole and slide on the outer wall of the slider; U-shaped rod one is fixedly connected to the top of the rodless cylinder slider on the left and right sides, and moves through the processing table; The second U-shaped rod is fixedly connected to the top of the rodless cylinder slider on both the front and rear sides, and moves through the processing table. Limiting sliding columns are slidably connected to the outer walls of U-shaped rod one and U-shaped rod two, respectively, for installing the drilling mechanism.

[0006] Preferably, the punching mechanism includes: A multi-stage push rod is fixedly connected to the bottom of the limiting slide column, and a drilling machine is fixedly connected to the bottom of the multi-stage push rod for drilling holes in the plywood.

[0007] Preferably, the inner side of the U-shaped processing table is provided with a support component for supporting the plywood, the support component including: Multiple sliding plates are slidably connected to the outer walls of the sliding rods on the front and rear sides, and are spaced apart on both sides of the rodless cylinder slider; Multiple springs are fitted onto the outer wall of the slide bar and located on both sides of the skateboard to propel the skateboard forward.

The rotating drum, rotatably connected to the movable blocks on the front and rear sides, is used to support the plywood.

[0008] Preferably, the rodless cylinder slider is provided with a lower recovery assembly for recovering wood chips generated during drilling from below. The lower recovery assembly includes: Multiple mounting rods are fixedly connected in pairs to the rodless cylinder sliders on the front and rear sides and the left and right sides respectively; Multiple limiting slide rods are slidably connected to the outer wall of the mounting rod at the intersection to limit the movement of the mounting rod; The fixing sleeve is fixedly connected to the outer wall of multiple limiting slide rods, and the inner wall of the fixing sleeve is slidably connected to the slide sleeve, which is used to abut against the lower part of the outer wall of the plywood to collect sawdust. A tension spring, fitted onto the outer wall of the sliding sleeve, is used to pull the sliding sleeve upwards and fit it against the underside of the plywood.

[0009] Preferably, the outer wall of the punching machine is provided with a negative pressure dust removal mechanism for adsorbing dust generated during punching. The negative pressure dust removal mechanism further includes: The movable sleeve is fixedly connected to the outer wall of the punching machine via a connecting plate; A wedge-shaped groove is provided below the movable sleeve, and an abutment sleeve is slidably connected inside the wedge-shaped groove. It is used to move up and down and fit against the top of the plywood to isolate dust.

The inner side of the arc-shaped push block is arc-shaped and fits against the inclined surface of the wedge-shaped groove. When the movable sleeve moves down and drives the wedge-shaped groove down, the arc-shaped push block moves away from the center.

[0012] Preferably, each arc-shaped push block has two arc-shaped grooves, and arc-shaped rods are fixedly connected to both sides of the inner wall of the arc-shaped grooves; Two wedge-shaped telescopic blocks are set on the inner wall of the arc-shaped groove and slide on the outer wall of the arc-shaped rod; Multiple springs are respectively fitted on the outer wall of each arc-shaped rod to push the wedge-shaped telescopic block to move outward, thereby expanding the contact range with the plywood.

[0013] The present invention, by adopting the above technical solution, can bring the following beneficial effects: 1. This desk board drilling device creates a temporary sealed chamber that fits tightly against the board surface when the drill bit contacts the board during drilling, completely surrounding the dust-generating point. An external negative pressure device directly extracts air from this sealed chamber, capturing the sawdust and dust generated during drilling at their source. This solves the problem of dust dispersion in traditional processing, effectively protecting the health of operators, avoiding the risk of dust explosions, and maintaining the cleanliness of the equipment and workshop environment, meeting the high standards of modern green production and occupational health and safety.

It has high positioning accuracy and good repeatability, making it very suitable for the complex process requirements of office desk panels that require multi-hole and non-positional processing, significantly improving processing accuracy and production flexibility.

[0015] 3. The desk's board drilling device features an elastic support component that automatically adapts to boards of different thicknesses and flatness. When the board is placed, the support point will adaptively adjust its height under pressure to ensure that the board is stably and horizontally supported, preventing problems such as hole edge cracking and dimensional deviation caused by the board being suspended or shaking during drilling. At the same time, the rotating drum provides a stable support surface and facilitates fine-tuning and alignment of the board, improving feeding efficiency and processing preparation speed.

[0024] The negative pressure dust removal mechanism 6 also includes: Multiple arc-shaped blocks 66 are circumferentially and equidistantly connected on the inner side of the contact sleeve 63; Furthermore, an air pipe is installed above the connecting plate 62 for connecting to an external negative pressure adsorption device to extract the sawdust generated during drilling. The telescopic component 67 is located inside the abutment sleeve 63 and is used to push the wood chips generated during drilling when the device is in motion.

The inner side of the arc-shaped push block 671 is arc-shaped and fits against the inclined surface of the wedge-shaped groove 64. When the movable sleeve 61 moves down and drives the wedge-shaped groove 64 down, the arc-shaped push block 671 moves away from the center.

[0026] Each arc-shaped push block 671 has two arc-shaped grooves 674 inside, and arc-shaped rods 676 are fixedly connected to both sides of the inner wall of the arc-shaped grooves 674 respectively. Two wedge-shaped telescopic blocks 675 are disposed on the inner wall of the arc-shaped groove 674 and slide on the outer wall of the arc-shaped rod 676; Multiple springs 677 are respectively sleeved on the outer wall of each arc-shaped rod 676 to push the wedge-shaped telescopic block 675 to move outward, thereby expanding the contact range with the plywood 3.

[0027] Working principle:

[0028] The plywood 3 to be processed is placed on the support assembly 49 above the processing table 1. When the board is placed, its weight presses down the rotating cylinder 497, forcing the movable block 494 to move down along the limiting rod 495 and compress the spring 496. This elastic design can adapt to boards of different thicknesses and slight warping, providing stable support. The design of the rotating cylinder 497 allows the board to be easily pushed when the board's plane position needs to be finely adjusted, reducing friction. The adjustment mechanism 4 is responsible for driving the drilling unit to make precise two-dimensional movements on the processing table plane in the X and Y axes. The external air source drives the rodless cylinder slider 42. The rodless cylinder slider 42 located on the left and right sides controls the movement of the Y axis, and the rodless cylinder slider 42 located on the front and rear sides controls the movement of the X axis. The top of the rodless cylinder slider 42 is fixed with a U-shaped rod 46 or a U-shaped rod 47. The limiting slide column 48 is simultaneously slidably connected to the two intersecting U-shaped rods. When the rodless cylinder slider 42 moves, it can drive the limiting slide column 48 and the entire drilling mechanism 5 installed on it to reach any target coordinate position above the plate, and complete the precise positioning. After positioning, the multi-stage push rod 51 is activated, pushing the drilling machine 52 downward to drill. In the initial stage of the drilling machine 52's downward movement, the movable sleeve 61 fixed to the machine body moves down synchronously. The inclined surface of the wedge-shaped groove 64 at the bottom of the movable sleeve 61 will press the arc-shaped push block 671 of the telescopic component 67, overcoming the tension of the elastic ring 673 and causing it to expand radially outward. At the same time, the spring three 65 pushes the contact sleeve 63 downward continuously, so that its bottom surface is tightly attached to the upper surface of the plywood 3. The expanded arc-shaped push block 671 and the contact sleeve 63 together form a temporary sealed dust removal chamber that is close to the board and surrounds the drill bit. The wedge-shaped telescopic block 675 inside the arc-shaped push block 671 extends further under the action of the spring four 677 to fill the gap. External negative pressure equipment, such as industrial vacuum cleaners, continuously draw air from this temporary sealed chamber through the air pipe on the connecting plate 62. Most of the sawdust and dust generated during drilling are sucked into the dust removal system by the powerful airflow the moment they are generated, thus achieving collection from the source of dust generation. When the drilling mechanism moves to a certain position, the lower sliding sleeve 452, under the action of the tension spring 453, always keeps in close contact with the lower surface of the board. Wood chips or dust that may penetrate from the back of the drill hole will be caught by the bottom collection port that moves with it and will be drawn away through the pipe connected to it, complementing the top negative pressure system and preventing wood chips from falling onto the workbench or the ground. After drilling is completed, the multi-stage push rod 51 retracts, driving the drilling machine 52 and the entire negative pressure dust removal mechanism 6 to rise. During the rising process, the pressure of the wedge groove 64 on the arc-shaped push block 671 is released, and the elastic ring 673 pulls it back to the converged state. During the contraction process, it slides on the surface of the plywood 3, thereby moving and cleaning the wood chips on the surface of the plywood 3. After the pressure of the wedge groove 64 on the arc-shaped push block 671 is completely released, it slowly moves away from the surface of the board. Then, the adjustment mechanism 4 can drive the drilling unit to move quickly to the next drilling point and start a new work cycle.

[0029] This invention provides a drilling device for processing office desk panels. Many methods and approaches exist to achieve this technical solution; the above description is merely a preferred embodiment of the invention. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principles of this invention, and these improvements and modifications should also be considered within the scope of protection of this invention. All components not explicitly stated in this embodiment can be implemented using existing technologies.
