Description

Technical Field

[0001] This utility model relates to the field of wood cutting technology, specifically to a clamping device for cutting wood. Background Technology

[0002] Wood panels are made from natural wood through multiple processing steps, including impurity removal, drying, and cutting. Because the wood comes from sustainably grown forest resources, wood panels are considered a natural and renewable material. Due to their dense fibrous structure, wood panels possess very high physical strength, allowing them to stably and effectively bear various heavy objects over long periods of use. Furthermore, wood panels retain the original natural grain and texture of the wood, giving them a unique natural aesthetic and making them widely used in furniture manufacturing. These characteristics significantly enhance the overall aesthetics of furniture, making wood a popular and widely appreciated material in furniture making.

[0003] In the process of wood panel processing, the first step is to cut the wood panels according to the structure and dimensions of the furniture design using cutting equipment. After cutting, the wood panels need to undergo a series of processing steps, including edge trimming, sanding, drilling, assembly, and painting, before finally being made into furniture that meets the design requirements. Therefore, the cutting process not only directly affects the quality of the wood panel assembly but also plays a decisive role in the overall dimensions of the furniture, making it the core process of wood panel processing. To prevent the wood panels from wobbling during the cutting process and affecting the cutting quality, clamps must be used to fix the wood panels in place. To facilitate fixing the wood panels, a telescopic cylinder and pressure plate assembly is used. The telescopic cylinder moves the pressure plate toward the cutting surface of the cutting equipment, using the pressure plate to tightly press and fix the wood panels to the cutting surface of the equipment. Then, a saw blade is used to cut the wood panels to complete the cutting operation. After cutting, the wood panels that meet the furniture design requirements are removed from the back of the saw blade to complete subsequent processing requirements. However, in practice, because the pressure plate and telescopic cylinder are located above the wooden board, to prevent the board from colliding with the pressure plate, the board must first be moved from under the pressure plate before it can be removed from the cutting equipment. This handling method is quite cumbersome. Therefore, there are shortcomings in the clamping of the wooden board, which hinders the removal of the cut board and improves the cutting efficiency, thereby enhancing overall processing efficiency and furniture quality. Summary of the Invention

The stop block is located between the two guide rails, and its two sides are connected to the two fixing blocks respectively.

[0007] Preferably, the stop block is provided with two baffles, which are respectively installed on the top of the two sides of the stop block. The bottom surfaces of the two baffles are in contact with the top surfaces of the two fixed blocks. An n-shaped fixing frame is provided between the two fixed blocks. The bottom two sides of the fixing frame are respectively installed on the two fixed blocks. The side of the two baffles away from the stop block is provided with a through hole, which is movably fitted onto the fixing frame. A telescopic cylinder II is vertically provided on the fixing frame. The telescopic cylinder II is installed at the top center of the fixing frame. The telescopic rod of the telescopic cylinder II is installed at the top center of the stop block. The side of the two baffles near the stop block is provided with a through hole, which is movably fitted onto a nut.

[0008] Preferably, the telescopic cylinder 2 is vertically provided with fixing rods on both sides, the bottom end of the fixing rod is installed on the stop block, and a fixing tube is movably fitted on the fixing rod. The fixing tube is installed on the top of the fixing frame, and a fixing hole is opened on the top of the fixing frame. The fixing rod is movably fitted into the fixing hole, and the diameter of the fixing hole and the inner diameter of the fixing tube are respectively matched with the diameter of the fixing rod.

[0009] Preferably, a cutting groove is provided on one side of the fixed plate, and a pressure plate is provided on the side of the cutting groove away from the fixed plate. Two telescopic cylinders are provided on the pressure plate, and the two telescopic cylinders are respectively installed on both sides of the plate. The telescopic rods of the two telescopic cylinders are respectively installed on the two ends of the pressure plate. Pressure strips are provided below the pressure plates, and a plurality of threaded holes are evenly provided on the pressure strips. The plurality of threaded holes are respectively opened in the vertical direction on the pressure strips. Bolts are threadedly fitted on the plurality of threaded holes.

[0012] The advantages of this invention are as follows: First, the invention uses a pressure plate and two telescopic cylinders to press and fix the wooden board placed on the flat plate, thus preventing the board from shaking during the cutting process and ensuring the quality of the cutting. Second, the invention uses a slot in the flat plate to assemble a fixing plate inside the plate. The fixing plate is hinged to the cutting table on its outer side, allowing it to rotate around the hinge point. A support plate restricts the rotation of the fixing plate, preventing it from rotating into the cutting table. Third, the invention uses a bracket and rollers on the telescopic cylinder to extend, first releasing the clamp on the wood placed on the flat plate. As the rollers rise, they drive the fixing plate to rotate around the hinge point, allowing the wooden board on the fixing plate to slide out along the inclined surface for quick removal of the cut wood, making the cutting process smoother and more efficient.

[0013] Secondly, this invention uses a stop block to position the cutting length of the wooden board, facilitating the cutting of boards to the desired length for furniture design. A slider, screw, and nut clamp the fixing block and stop block onto a guide rail. Adjusting the position of the fixing block and stop block on the guide rail allows for adjustment of the cutting length, enabling the cutting of boards of various lengths. Furthermore, the invention uses a fixing frame and a telescopic cylinder to raise and lower the stop block and baffle, allowing the cut board to slide along the fixing plate, thus preventing the stop block from interfering with the board's movement. A fixing rod and fixing tube limit the up-and-down movement of the stop block, reducing wobbling during raising and lowering and improving the stability of the stop block's movement.

[0014] Furthermore, this invention utilizes a second pressure plate and two telescopic cylinders to press and fix the wooden board on one side of the cutting groove onto the flat plate. The first and second pressure plates clamp the wooden boards on both sides of the cut surface, ensuring reliable clamping. A pressure strip, bolt one, and a spring buffer the pressure exerted on the wooden board by the first and second pressure plates, preventing damage and improving the clamping effect. Bolt two further presses and fixes bolt one, enhancing its fixing effect. Moreover, this invention uses a connecting plate to connect the bracket to the telescopic rod of the first telescopic cylinder, preventing collisions between the bracket and the cylinder body during the telescopic cylinder's extension and retraction.

[0022] like Figures 1 to 7As shown, a clamping device for cutting wood includes a flat plate 2 at the top of a cutting table 1. A groove 3 is formed on the flat plate 2, and a fixing plate 4 is movably fitted within the groove 3. The outer side of the fixing plate 4 is hinged to the cutting table 1. A support plate 5 is provided on the inner side of the fixing plate 4, and the support plate 5 is mounted on the bottom surface of the flat plate 2. The top surface of the support plate 5 contacts the bottom surface of the fixing plate 4, allowing the fixing plate 4 to rotate around the hinge point between the fixing plate 4 and the cutting table 1. By controlling the tilting of the fixing plate 4, the wood placed on the fixing plate 4 slides out along the tilted surface for quick removal of the cut wood. A pressing mechanism is provided on one side of the fixing plate 4. The pressing mechanism includes a pressure plate 6 above the fixing plate 4, two vertically mounted telescopic cylinders 7 on the pressure plate 6, an L-shaped bracket 8 on the two telescopic cylinders 7, and rollers 9 on the bracket 8. The two telescopic cylinders 7 are respectively mounted on both sides of the flat plate 2, and the top of the bracket 8 and the pressure plate 6... The ends of the rollers are connected to the telescopic rods of the telescopic cylinders 7 and rotatably mounted on the bottom of the bracket 8. The rollers 9 are located below the fixed plate 4. The plate 2 has a through groove 10, which is connected to the sleeve groove 3. The through groove 10 is movably mounted on the bracket 8. By controlling the two telescopic cylinders 7 to retract, the pressure plate 6, the bracket 8, and the rollers 9 are moved downward, thereby using the pressure plate 6 to pressurize the fixed plate 4, thus facilitating the clamping of the wood placed on the fixed plate 4. Between 4 and pressure plate 6, conversely, when the two telescopic cylinders 7 are extended, they drive pressure plate 6, bracket 8 and roller 9 to move upward, thus first releasing the clamping operation on the wood placed on the fixed plate 4. As roller 9 continues to rise, after roller 9 contacts the bottom surface of fixed plate 4, roller 9 will drive fixed plate 4 to rotate around the hinge between fixed plate 4 and cutting table 1, so that the wood placed on fixed plate 4 slides out along the inclined surface, so as to quickly take out the cut wood.

[0023] In this embodiment, the fixing plate 4 is provided with two guide rails 11 with convex-shaped internal cavities. The two guide rails 11 are respectively installed on both sides of the top surface of the fixing plate 4. The two guide rails 11 are respectively provided with convex-shaped sliders 12. The sliders 12 are provided with screws 13. The bottom end of the screws 13 is installed on the top end of the sliders 12. The upper middle part of the screws 13 passes through the guide rails 11. The screws 13 are threaded with nuts 14. The fixing block 15 is provided below the nuts 14. The fixing block 15 has a fixing groove 16 in its lower middle part. The fixing groove 16 is fitted onto the guide rails 11. The cross-sectional shape of the fixing groove 16 matches the outer cross-sectional shape of the guide rails 11. The fixing block 15 has a clamping hole, which is movably fitted onto the screw 13. The diameter of the clamping hole matches the diameter of the screw 13. The fixing block 15 is clamped onto the guide rail 11 by the nut 14, the screw 13, and the slider 12. Two fixing blocks 15 are used, and the two fixing blocks 15 are respectively assembled on the two guide rails 11. A stop block 17 is provided between the two fixing blocks 15. The two sides of the stop block 17 are connected to the two fixing blocks 15 respectively. By adjusting the position of the slider 12 fitted into the guide rail 11, the position of the fixing blocks 15 and the stop block 17 can be adjusted to adjust the length of the wood board to be cut.

[0024] Specifically, the stop block 17 is provided with two baffles 18, which are respectively installed on the top of the two sides of the stop block 17. The bottom surfaces of the two baffles 18 are in contact with the top surfaces of the two fixing blocks 15. An n-shaped fixing frame 19 is provided between the two fixing blocks 15. The bottom sides of the fixing frame 19 are respectively installed on the two fixing blocks 15. The two baffles 18 have through holes 20 on the side away from the stop block 17. The through holes 20 are movably fitted onto the fixing frame 19. The fixing frame 19 is vertically provided with... Telescopic cylinder 21 is installed at the top center of the fixed frame 19. The telescopic rod of telescopic cylinder 21 is installed at the top center of the stop block 17. The telescopic cylinder 21 can extend and retract, thereby driving the stop block 17 and the baffle 18 to rise and fall, so that the cut wooden board can slide out along the inclined fixed plate 4. The two baffles 18 are respectively provided with through holes 22 on the side near the stop block 17. The through holes 22 are movably fitted on the nut 14 to avoid the nut 14 interfering with the rising and falling of the stop block 17 and the baffle 18.

[0025] Please refer to it again. Figure 1 , 3In the telescopic cylinder 21, two vertical fixing rods 23 are respectively installed on both sides. The bottom end of the fixing rod 23 is installed on the stop block 17. A fixing tube 24 is movably fitted on the fixing rod 23. The fixing tube 24 is installed on the top of the fixing frame 19. A fixing hole is opened on the top of the fixing frame 19. The fixing rod 23 is movably fitted into the fixing hole. The diameter of the fixing hole and the inner diameter of the fixing tube 24 are respectively matched with the diameter of the fixing rod 23, thereby restricting the up and down movement of the stop block 17, reducing the occurrence of wobbling of the stop block 17, and thus improving the stability of the up and down movement of the stop block 17.

[0026] In this embodiment, a cutting groove 25 is provided on one side of the fixed plate 4, and a saw blade is fitted inside the cutting groove 25. A motor is provided on one side of the saw blade, and a reciprocating mechanism is provided in the cutting table 1 to drive the motor to move along the cutting groove 25, thereby facilitating the cutting of the wood board.

Two telescopic cylinders 27 are provided on the pressure plate 26, and the two telescopic cylinders 27 are respectively installed on both sides of the flat plate 2. The telescopic rods of two telescopic cylinders 7 are respectively installed on both ends of the pressure plate 26. The retraction of the telescopic cylinders 27 is used to press and fix the wood board on one side of the cutting groove 25 onto the flat plate 2, thereby using the pressure plate 6 and the pressure plate 26 to clamp the wood board on both sides of the cutting, ensuring the reliability of the clamping; the pressure plate 6 and the pressure plate 26 respectively clamp the wood board on both sides of the cutting. Below the first plate 6 and the second pressure plate 26, pressure strips 28 are respectively provided. Several threaded holes 1 are evenly opened on the pressure strips 28, and several threaded holes 1 are opened vertically on the pressure strips 28. Bolts 1 29 are threadedly fitted on the several threaded holes 1. Both the first plate 6 and the second pressure plate 26 have sleeve holes, which are fitted on the bolts 1 29. The diameter of the sleeve hole matches the diameter of the bolts 1 29. The nut of the bolts 1 29 contacts the top surface of the first plate 6 or the second pressure plate 26. A spring 30 is movably fitted on the bolts 1 29. The bottom end of the spring 30 contacts the pressure strips 28, and the top end of the spring 30 contacts the first plate 6 or the second pressure plate 26, thereby buffering the pressure of the first plate 6 and the second pressure plate 26 on the wooden board, avoiding damage to the wooden board, and improving the clamping effect of the wooden board.

[0027] Specifically, the pressure strip 28 has a threaded hole 2 on the side away from the cutting groove 25 along the horizontal direction. The threaded hole 2 is connected to the threaded hole 1 in the pressure strip 28. The threaded hole 2 is fitted with a bolt 2 31. One end of the bolt 2 31 contacts one end of the bolt 1 29, thereby pressing and fixing the bolt 1 29 to improve the fixing effect of the bolt 1 29.

[0028] Please participate again. Figure 6The telescopic cylinder 7 is located between the roller 9 and the support plate 5. The diameter of the roller 9 is not less than the width of the bracket 8 to prevent the bottom of the bracket 8 from contacting the bottom surface of the fixed plate 4 and to prevent the bracket 8 from scratching the fixed plate 4. A connecting plate 32 is provided on one side of the bracket 8. One end of the connecting plate 32 is installed on the top of the bracket 8, and the other end of the connecting plate 32 is installed on the telescopic rod of the telescopic cylinder 7. The connecting plate 32 is located below the pressure plate 6, thereby preventing the bracket 8 from colliding with the cylinder body of the telescopic cylinder 7 during the telescopic movement of the telescopic cylinder 7.

[0029] The instructions for using this product are as follows: Figures 1 to 7 As shown, firstly, according to the furniture design requirements, the stop block 17 and the baffle plate 18 are moved along the guide rail 11 until the distance between the stop block 17 and the cutting groove 25 matches the predetermined length of the wood board to be cut. The stop block 17 and the baffle plate 18 are then firmly clamped onto the guide rail 11 by tightening the nut 14. Next, the two telescopic cylinders 1-7 are controlled to shorten, bringing the plate 2 into contact with the support plate 5. The wood board to be cut is placed on the plate 1, ensuring one side of the board is in close contact with the stop block 17 to guarantee cutting accuracy. Then, the two telescopic cylinders 1-7 and 2-3-26 are controlled to shorten synchronously, using the pressure plate 1-6 and pressure plate 2-27 to press and fix both sides of the wood board. The wood board is then cut using a saw blade to complete the cutting operation. After the cutting process is completed, the telescopic cylinder 7 and the two telescopic cylinders 26 are extended to release the pressure on the wooden board. As the roller 9 continues to rise, after the roller 9 contacts the bottom surface of the fixed plate 4, the roller 9 drives the fixed plate 4 to rotate around the hinge between the fixed plate 4 and the cutting table 1, so that the wooden board placed on the fixed plate 4 slides out along the inclined surface to quickly remove the cut wooden board.

[0030] In this embodiment, the pressure plate 6 and two telescopic cylinders 7 are used to press and fix the wooden board placed on the flat plate 2, thereby preventing the wooden board from shaking during the cutting process and ensuring the quality of the cutting. Furthermore, the groove 3 on the flat plate 2 allows the fixing plate 4 to be assembled inside the flat plate 2. The outer side of the fixing plate 4 is hinged to the cutting table 1, allowing the fixing plate 4 to rotate around the hinge point between the fixing plate 4 and the cutting table 1. The support plate 5 restricts the rotation of the fixing plate 4, preventing it from rotating into the cutting table 1. In addition, the bracket 8 and roller 9 on the telescopic cylinder 7 allow the telescopic cylinder 7 to extend, first releasing the clamp on the wood placed on the flat plate. As the roller 9 continues to rise, it drives the fixing plate 4 to rotate around the hinge point between the fixing plate 4 and the cutting table 1, allowing the wooden board placed on the fixing plate 4 to slide out along the inclined surface for quick removal of the cut wooden board, making the cutting process smoother and more efficient.

[0031] The embodiments described above are merely preferred embodiments of this utility model and are not intended to limit the scope of implementation of this utility model. Therefore, all equivalent changes or modifications made to the structure, features and principles described in the patent claims of this utility model should be included within the scope of the patent application of this utility model.
