Description

Technical Field

[0001] This utility model belongs to the field of wood processing technology, and specifically relates to a fixture for fiberboard production. Background Technology

[0002] Fiberboard production fixtures are used to process fiberboard. However, traditional fiberboard production fixtures have poor adaptability and require custom-made fixtures for different specifications of fiberboard. This not only increases equipment costs but also causes production line downtime due to frequent replacements. In addition, rigid contact during clamping can easily cause indentations or scratches on the surface of the fiberboard. They cannot effectively absorb the vibration energy of the equipment during operation, resulting in micro-displacement of the fiberboard during production and processing, which affects the accuracy of cutting and drilling.

[0003] To address the problems mentioned in the background above, a fixture for fiberboard production is proposed. Utility Model Content

[0004] The purpose of this utility model is to provide a clamp for fiberboard production, which has the advantages of multi-specification clamping and clamping buffer.

[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a fixture for fiberboard production, including a base, supports on both sides of the top of the base, a top box bolted to the top of the supports, a rotating rod passing through and rotatably connected to the front end of the top box, a vertical bevel gear fixedly sleeved on the middle and rear end of the rotating rod, a horizontal bevel gear meshing with the bottom of the vertical bevel gear, a screw fixedly sleeved inside the horizontal bevel gear, and the top of the screw passing through and rotatably connected to the front and rear ends of the bottom of the top box, a threaded sleeve threadedly connected to the middle and bottom of the screw, a clamping plate bolted to the side opposite to the threaded sleeve at one end, and a buffer mechanism provided on the side opposite to the clamping plate at one end.

[0006] The above technical solution involves rotating a rotating rod, which in turn drives a vertical bevel gear to rotate synchronously. This rotation, in turn, drives a horizontal bevel gear, which in turn drives a screw. The screw's rotation causes the two threaded sleeves to move relative to each other, resulting in the clamping plates moving synchronously to hold the fiberboard. Reversing the rotation of the rotating rod causes the clamping plates to separate, releasing the fiberboard. This design flexibly adapts to different specifications of fiberboard, ensuring stable clamping and effectively preventing displacement or deformation during production. Its versatility reduces downtime due to frequent fixture changes, improving production efficiency. Simultaneously, the stable clamping of the fiberboard's four corners ensures finished product quality, providing reliable support for continuous and standardized production.

[0007] The present invention is further configured such that the buffer mechanism includes a spring, the spring is bolted to the side opposite to one end of the clamping plate, a damper is sleeved inside the spring, and a clamping block is bolted to the end of the spring away from the clamping plate.

[0008] The above technical solution employs a buffer mechanism. When the clamping plate moves towards the fiberboard, the clamping block connected to the spring first contacts the fiberboard surface. As the clamping plate continues to approach the fiberboard, the clamping block experiences a reaction force from the fiberboard, pushing the spring to compress. During compression, the spring converts the rigid thrust transmitted by the clamping plate into elastic potential energy, absorbing the initial impact force through deformation. This prevents rigid collisions between the clamping block and the fiberboard, thus avoiding damage to the board surface. Simultaneously, the spring force increases with the compression, gradually increasing the pressure of the clamping block on the fiberboard, achieving progressive clamping. The damper nested inside the spring works synchronously, its piston rod extending and retracting with the spring compression. The viscous resistance of the damping medium suppresses the rapid deformation and rebound of the spring. When the spring fluctuates due to external forces... When vibration tends to occur, the damper can quickly attenuate the vibration energy, preventing the clamping block from bouncing or swaying at high frequency on the fiberboard surface, ensuring a smooth clamping process. After the clamping plate moves to the preset clamping position, the spring maintains a certain amount of compression. Its elastic force applies stable pressure through the clamping block to fix the fiberboard, while the damper maintains the static compression state of the spring, avoiding repeated expansion and contraction of the spring due to processing vibration, ensuring the continuity and stability of the clamping force. The buffer design can dynamically adjust the clamping pressure, ensuring that the board is firmly fixed while avoiding surface indentations caused by rigid impact. It effectively absorbs equipment vibration during production and processing, preventing cutting deviations caused by micro-displacement of the board. Its adaptive characteristics can accommodate the clamping needs of boards of different thicknesses, reducing manual adjustment time and extending the service life of the clamp.

[0009] The present invention is further configured such that a slider is welded to the side opposite to the screw sleeve at one end, and a groove is provided at the front end and rear end of the top and bottom of the two supports opposite to each other, and the interior of the groove is slidably connected to the surface of the slider.

[0010] The above technical solution, by setting slider one and slide groove one, can limit the movement of the screw sleeve.

[0011] The present invention is further configured such that a slider two is bolted to the bottom of the bracket, and two sliding grooves two are provided on both sides of the top front end and rear end of the base, and the interior of the sliding groove two is slidably connected to the surface of the slider two.

[0012] The above technical solution is adopted: by setting slider two and slide groove two, the movement of the bracket can be limited.

[0013] The present invention is further configured such that slots are provided on both sides of the front and back of the base, and a locking bolt is threadedly connected to the opposite side of the slider on one side, and the surface of the locking bolt penetrates the interior of the slot.

[0014] The above technical solution is adopted: by setting the slot and locking bolt, the movement of the bracket can be limited by the second slider after the bracket is moved by tightening the locking bolt, and the slot can prevent the locking bolt from moving.

[0015] The present invention is further configured such that the screw is configured with a bidirectional thread.

[0016] The above technical solution allows the two connected sleeves to move in opposite directions by rotating the screw, which can be configured as a two-way bolt.

[0017] The present invention is further provided that a protective pad is adhered to the side of the clamping block away from the clamping plate.

[0018] The above technical solution, by setting up a protective pad, can prevent the clamping blocks from damaging the fiberboard.

[0019] The present invention is further configured such that a bearing is rotatably connected to the back of the rotating rod and the bottom of the screw.

[0020] The above technical solution, by incorporating bearings, can stabilize the rotating rod and the screw.

[0021] In summary, this utility model has the following beneficial effects:

[0022] 1. This utility model can flexibly adapt to different specifications of plates, clamping to ensure the plates are firmly fixed, effectively preventing displacement or deformation during production and processing. Its universal design reduces downtime due to frequent changes of clamps, improves production efficiency, and at the same time, it firmly clamps the four corners of the plates to ensure the quality of finished products, providing reliable support for continuous and standardized production.

[0023] 2. This utility model can dynamically adjust the clamping pressure through a buffer design, which not only ensures the plate is firmly fixed but also avoids surface indentations caused by rigid impact. It effectively absorbs equipment vibration during production and processing, prevents cutting deviations caused by micro-displacement of the plate. Its adaptive characteristics can accommodate the clamping needs of plates of different thicknesses, reduce manual adjustment time, and extend the service life of the fixture.

[0030] Example 1:

[0031] refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 A fixture for fiberboard production includes a base 1, with supports 2 on both sides of the top of the base 1. A top box 3 is bolted to the top of the supports 2. A rotating rod 4 is rotatably connected through the front end of the top box 3. A vertical bevel gear 5 is fixedly sleeved on the middle and rear end of the rotating rod 4. A horizontal bevel gear 6 meshes with the bottom of the vertical bevel gear 5. The vertical bevel gear 5 and the horizontal bevel gear 6 have a module of 2-3, a number of teeth of 20-30, a tooth surface hardness of HRC58-62, and a meshing clearance of 0.1-0.2mm. A screw 7 is fixedly sleeved inside the horizontal bevel gear 6, and the top of the screw 7 passes through the front end and rear end of the bottom of the top box 3 and is rotatably connected.

A buffer mechanism is set on the opposite side of the clamping plate 9 at one end. Rotating the rotating rod 4 drives the vertical bevel gear 5 to rotate synchronously with the rotating rod 4. The rotation of the vertical bevel gear 5 drives the horizontal bevel gear 6 to rotate. The rotation of the horizontal bevel gear 6 drives the screw rod 7 to rotate. The rotation of the screw rod 7 drives the two threaded sleeves 8 to move relative to each other, and drives the clamping plate 9 to move synchronously to clamp the fiberboard. When the rotating rod 4 is rotated in the opposite direction, the clamping plate 9 separates and releases the fiberboard. It can flexibly adapt to fiberboards of different specifications.

[0032] refer to Figure 1 , Figure 2 , Figure 3 , Figure 4A slider 13 is welded to the opposite side of the threaded sleeve 8 at one end. The front and rear ends of the top and bottom of the two supports 2 are provided with grooves 14, and the interior of the grooves 14 is slidably connected to the surface of the slider 13. By setting the slider 13 and the grooves 14, the movement of the threaded sleeve 8 can be limited.

[0033] refer to Figure 1 The bottom of the bracket 2 is bolted with a slider 2 15. The front and rear sides of the top of the base 1 are provided with sliding grooves 2 16, and the inside of the sliding grooves 2 16 is slidably connected to the surface of the slider 2 15. By setting the slider 2 15 and the sliding grooves 2 16, the movement of the bracket 2 can be limited.

[0034] refer to Figure 1 The base 1 has slots 17 on both sides of the front and back. On the opposite side of the slider 15, a locking bolt 18 is threadedly connected, and the surface of the locking bolt 18 penetrates the interior of the slot 17. By setting the slots 17 and the locking bolt 18, the movement of the bracket 2 can be limited by tightening the locking bolt 18 after it moves, and the slots 17 can prevent the locking bolt 18 from moving. The locking bolt 18 is an M8 to M12 hexagon socket head cap screw with a preload torque of 15 to 25 N·m, and is used with an anti-loosening nut.

[0037] Example 2:

[0038] refer to Figure 1 , Figure 3 , Figure 4A clamp for fiberboard production includes a buffer mechanism comprising a spring 10, which is bolted to the opposite side of a clamping plate 9 at one end. The spring 10 is a cylindrical helical compression spring with a wire diameter of 3-5 mm, a mean diameter of 20-25 mm, a free length of 50-80 mm, and a spring constant of 15-30 N / mm. A damper 11 is sleeved inside the spring 10. The damper 11 is a hydraulic damper with a stroke of 30-60 mm, a damping constant of 5-10 N·s / mm, and a maximum bearing capacity of 500 N. A clamping block 12 is bolted to the end of the spring 10 away from the clamping plate 9. When the clamping plate 9 moves towards the fiberboard, the clamping block 12 connected to the spring 10 first contacts the surface of the fiberboard. As the clamping plate 9 continues to approach the fiberboard, the clamping block 12 receives a reaction force from the fiberboard, pushing the spring 10 to begin compression. During the compression process, the spring 10 converts the rigid thrust transmitted by the clamping plate 9 into elastic potential energy, absorbing the initial clamping force through deformation. The impact force is reduced to prevent rigid collision between the clamping block 12 and the fiberboard, thus avoiding damage to the fiberboard surface. At the same time, the elastic force of the spring 10 increases with the increase of the compression amount, so that the pressure of the clamping block 12 on the fiberboard gradually increases, realizing progressive clamping. The damper 11 nested inside the spring 10 works synchronously. Its piston rod extends and retracts with the compression of the spring 10. The viscous resistance of the damping medium suppresses the rapid deformation and rebound of the spring 10. When the spring 10 has a tendency to vibrate due to external force fluctuations, the damper 11 can quickly attenuate the vibration energy, preventing the clamping block 12 from bouncing or high-frequency shaking on the surface of the fiberboard, ensuring a smooth clamping process. After the clamping plate 9 moves to the preset clamping position, the spring 10 maintains a certain amount of compression. Its elastic force applies stable pressure through the clamping block 12 to fix the fiberboard. The damper 11 maintains the static compression state of the spring 10, avoiding repeated extension and retraction of the spring 10 due to processing vibration, and ensuring the continuity and stability of the clamping force.

[0039] refer to Figure 1 , Figure 3 , Figure 4 A protective pad 19 is attached to the side of the clamping block 12 away from the spring 10. By setting the protective pad 19, the clamping block 12 can be prevented from damaging the fiberboard. It is made of silicone, with a thickness of 3-5mm and a Shore hardness of 60-70A. The surface is decorated with diamond-shaped anti-slip texture with a texture depth of 0.5mm.

[0040] Brief description of the operation: Rotating the rotating rod 4 causes the vertical bevel gear 5 to rotate synchronously with the rotating rod 4. The rotation of the vertical bevel gear 5 drives the horizontal bevel gear 6 to rotate, which in turn drives the screw 7 to rotate. The rotation of the screw 7 causes the two threaded sleeves 8 to move relative to each other, which in turn causes the clamping plate 9 to move synchronously to clamp the fiberboard. When rotating the rotating rod 4 in the opposite direction, the clamping plate 9 separates and releases the fiberboard. It can flexibly adapt to different specifications of fiberboard. When the clamping plate 9 moves toward the fiberboard, the clamping block 12 connected to the spring 10 first contacts the surface of the fiberboard. At this time, as the clamping plate 9 continues to approach the fiberboard, the clamping block 12 is subjected to the reaction force of the fiberboard, which pushes the spring 10 to begin to compress. During the compression process, the spring 10 converts the rigid thrust transmitted by the clamping plate 9 into elastic potential energy, which absorbs the impact force at the beginning of clamping through deformation, avoiding rigid collision between the clamping block 12 and the fiberboard. This causes damage to the fiberboard surface. At the same time, the elastic force of the spring 10 increases with the increase of the compression amount, causing the pressure of the clamping block 12 on the fiberboard to gradually increase, achieving progressive clamping. The damper 11 nested inside the spring 10 works synchronously. Its piston rod extends and retracts with the compression of the spring 10. The viscous resistance of the damping medium suppresses the rapid deformation and rebound of the spring 10. When the spring 10 has a tendency to vibrate due to external force fluctuations, the damper 11 can quickly attenuate the vibration energy, preventing the clamping block 12 from bouncing or high-frequency shaking on the surface of the fiberboard, ensuring a smooth clamping process. After the clamping plate 9 moves to the preset clamping position, the spring 10 maintains a certain amount of compression. Its elastic force applies stable pressure through the clamping block 12 to fix the fiberboard. The damper 11 maintains the static compression state of the spring 10, avoiding repeated extension and retraction of the spring 10 due to processing vibration, and ensuring the continuity and stability of the clamping force.
