Description

Technical Field

[0001] This utility model relates to the field of drilling clamping technology, specifically a clamping structure for wood product processing. Background Technology

[0002] Wood is the lignified tissue formed by continuously growing plants, such as trees and shrubs. After the initial growth of these plants, the vascular cambium in the rootstock begins to activate, developing phloem outward and wood inward. Most high-end furniture currently uses solid wood boards as raw materials, which are then processed into boards or other wood products. In the production of wood products, drilling is required. Currently, the clamping mechanisms on drilling equipment can only clamp wood products with regular shapes. However, in actual processing, the shapes of wood products are often diverse and not regular, making it impossible to achieve stable clamping fixtures. During the drilling process, deviations are prone to occur, thus affecting the drilling quality. Utility Model Content

Detailed Implementation

[0014] Example 1

[0015] like Figure 1 and Figure 2As shown, a clamping structure for wood product processing includes a drilling worktable 1. A rectangular mounting groove 2 is formed through the drilling worktable 1, and a support mold 3 is installed in the rectangular mounting groove 2. A limiting groove 4 is formed on the support mold 3, and the shape and size of the limiting groove 4 match the shape and size of the wood product. A support boss 5 is fixed to the inner wall of the limiting groove 4. A pressing component is provided on both sides of the limiting groove 4 on the drilling worktable 1. The pressing component includes a transverse sliding plate 6, a longitudinal sliding plate 7, and a pressing shaft 8. The transverse sliding plate 6 is slidably mounted on the drilling worktable 1, and the longitudinal sliding plate 7 is slidably mounted on the transverse sliding plate 6. The movement direction of the transverse sliding plate 6 is perpendicular to the movement direction of the longitudinal sliding plate 7. The pressing shaft 8 is mounted on the longitudinal sliding plate 7 and has the freedom to move along the height direction of the drilling worktable 1. A corresponding support mold 3 is configured for irregularly shaped wood products. The corresponding support mold 3 is installed on the drilling worktable 1, and the limiting groove 4 on the support mold 3 matches the shape and size of the wood product. The wood product is placed in the limiting groove 4 for drilling processing. The wooden product is supported by the support boss 5, allowing the drill bit to pass smoothly through the wooden product to complete the drilling process. The matching of the limiting groove 4 with the wooden product restricts the horizontal freedom of movement of the wooden product. Then, the pressing shaft 8 presses the wooden product against the support boss 5, thereby restricting the vertical freedom of movement of the wooden product. This provides strong clamping strength for the wooden product, ensuring that it will not shift during the drilling process and that the drilling quality will not be affected. Since some wooden products need to be drilled with multiple holes in different locations, the pressing shaft 8 may block the drilling position of the wooden product. Therefore, the pressing shaft 8 has two degrees of freedom in the horizontal plane. The movement of the transverse sliding plate 6 gives the pressing shaft 8 the freedom of movement in the X-axis direction, and the movement of the longitudinal sliding plate 7 gives the pressing shaft 8 the freedom of movement in the Y-axis direction. This allows the pressing shaft 8 to adjust its contact position with the wooden product, avoiding the drilling position of the wooden product on the one hand, and finding a suitable position to press the wooden board down to achieve a better clamping effect on the other hand.

[0016] Example 2

[0017] Based on Example 1, such as Figure 1 and Figure 2As shown, a flange 19 is fixedly fitted on the support mold 3. Multiple threaded holes 20 are opened around the rectangular mounting groove 2 on the drilling workbench 1. Multiple bolts 21 are provided on the flange 19. The threads of the bolts 21 are adapted to the threaded holes 20. The support mold 3 is installed on the drilling workbench 1 in a detachable manner. The external dimensions and sizes of each support mold 3 are the same, so that different support molds 3 can be adapted to the rectangular mounting groove 2. The upper limit groove 4 of different support molds 3 has different sizes and shapes to match the shape and size of the wooden products. When the support mold 3 is assembled into the rectangular mounting groove 2, the flange 19 contacts the top surface of the drilling workbench 1. Finally, the screws 21 are tightened to connect the support mold 3 and the drilling workbench 1 together.

[0018] Example 3

[0019] Based on Example 2, such as Figure 1 and Figure 2 As shown, the drilling workbench 1 has a first lead screw groove 9, in which a first lead screw 10 is rotatably mounted. A first lead screw slider 11 is threaded onto the first lead screw 10. A transverse slide plate 6 is fixedly connected to the first lead screw slider 11. A first motor 12 is installed on the side wall of the drilling workbench 1. The output shaft of the first motor 12 is connected to the first lead screw 10. The first motor 12 drives the first lead screw 10 to rotate, causing the first lead screw slider 11 to move linearly along the axial direction of the first lead screw 10, thereby driving the transverse slide plate 6 to move linearly along the axial direction of the first lead screw 10. A second lead screw groove 13 is opened on the top of the transverse slide plate 6, in which a second lead screw 14 is rotatably mounted. A second lead screw slider 15 is threaded onto the second lead screw 14. The second lead screw slider 15 slides and adapts to the second lead screw groove 13. A longitudinal slide plate 7 is fixedly mounted on the second lead screw slider 15. The transverse slide plate 6... A second motor 16 is installed at one end, and the output shaft of the second motor 16 is connected to the second lead screw 14. The second motor 16 drives the second lead screw 14 to rotate, causing the second lead screw slider 15 to move linearly along the axis of the second lead screw 14. The second lead screw slider 15 drives the longitudinal slide plate 7 to move linearly along the axis of the second lead screw 14, so that the lower pressure shaft 8 has two degrees of freedom of movement in the horizontal plane, which facilitates the adjustment of the position of the lower pressure shaft 8 acting on the wooden product. A cylinder 17 is vertically installed on the top of the longitudinal slide plate 7. The telescopic shaft of the cylinder 17 is connected to the crossbeam 18. The lower pressure shaft 8 is fixed at the bottom of the crossbeam 18 away from the cylinder 17. The telescopic movement of the cylinder 17 drives the crossbeam 18 to move up and down, so that the lower pressure shaft 8 contacts the wooden product downward to complete the clamping action. The lower pressure shaft 8 moves upward away from the wooden product. At the same time, the lower pressure shaft 8 moves horizontally to the outside of the wooden product, so that the next wooden product can be replaced for drilling operation.
