Description

Technical Field

[0001] This utility model relates to the field of wood processing technology, specifically a wood quick positioning and clamping device. Background Technology

[0002] Timber is widely used in furniture, construction and other fields. Timber usually needs to go through many processing steps. Because the timber is too long and needs to be cut to the appropriate size, the traditional method is for workers to use a saw blade to cut the timber. This method is time-consuming and labor-intensive, and the cutting work is inefficient. Workers have to work on the cutting work for a long time, which increases the labor intensity of the workers.

[0003] Patent document CN112895021A discloses an anti-sway rapid wood cutting device, including a support, a support block fixed on the support, a support cavity on the support block for supporting the wood during processing, two guide grooves inside the support, a sliding block slidably disposed in the guide grooves, and a positioning clamping device fixed on the sliding block for initial positioning and clamping of the wood to be cut; a cutting device is provided, using double cutting blades to perform bidirectional rapid cutting of the wood, saving a significant amount of cutting time and replacing manual operation of cutting tools, improving cutting efficiency and saving a large amount of manpower and resources, while the positioning clamping device positions and clamps the wood to prevent swaying during cutting and avoids affecting the cutting quality.

[0004] Although the aforementioned application documents utilize positioning and clamping devices to position and clamp the wood, preventing it from swaying during cutting and thus avoiding affecting the cutting quality, the wood is only fixed on both sides during use. However, the lack of external wall support causes the wood to vibrate at high frequencies (chatter) under the force of the cutting tool. Especially during high-speed cutting, the processed surface will have ripples or burrs, reducing the surface finish.

[0005] Therefore, a rapid positioning and clamping device for wood is proposed to solve the problems mentioned above. Utility Model Content

[0006] To address the shortcomings of existing technologies, this utility model provides a rapid positioning and clamping device for wood, which solves the problems mentioned in the background section.

[0007] To achieve the above objectives, the present invention provides the following technical solution: including a base, wherein a fixing mechanism is assembled on the top of the base, and a groove is provided on the top of the base; The fixing mechanism includes a bidirectional threaded rod, which is rotatably connected to the inner wall of the base via a bearing. A movable block is threadedly connected to the outer wall of the bidirectional threaded rod. A fixed block is fixedly connected to the side of the movable block. A clamping plate is mounted on the side of the fixed block. An installation groove is opened on the side of the clamping plate. A second hydraulic chamber is mounted on the inner wall of the installation groove. A second hydraulic rod is slidably connected to a piston at one end inside the second hydraulic chamber. A gripper is fixedly connected to the front of the second hydraulic rod. A power assembly for driving the movable block and the gripper is mounted on the top of the base.

[0008] Preferably, the power assembly includes a motor, which is fixedly connected to the side of the base, and the bidirectional threaded rod extends laterally through the base, with the extended end of the bidirectional threaded rod fixedly connected to the output end of the motor.

[0009] Preferably, a first hydraulic chamber is fixedly connected to the inner walls of the moving block and the fixed block. A first hydraulic rod is slidably connected to one end of the piston inside the first hydraulic chamber. The side of the first hydraulic rod is fixedly connected to the side of the clamping plate, and a spring is movably sleeved on the outer wall of the first hydraulic rod.

[0010] Preferably, a connecting hose is fixedly connected to the side of the first hydraulic chamber, and the end of the connecting hose away from the first hydraulic chamber is fixedly connected to the side of the second hydraulic chamber.

[0011] Preferably, the two ends of the spring are fixedly connected to the side of the first hydraulic chamber and the side of the clamping plate, respectively.

[0012] Preferably, a limiting groove is formed on the top of the base, and a sliding plate is fixedly connected to the bottom of the clamping plate, the sliding plate being slidably connected to the inner wall of the limiting groove.

[0013] Preferably, the gripper is fixedly connected to a rubber sheet for increasing friction with the wood.

[0014] Compared with the prior art, this utility model provides a quick positioning and clamping device for wood, which has the following advantages: 1. After the outer wall of the wood is clamped by the rubber sheet from the front and back, the lateral degree of freedom of the wood is locked; the high-frequency cutting force of the tool cannot excite a sufficient amplitude, chatter is suppressed, the machined surface no longer has ripples or burrs, chatter disappears, and the cutting edge can always maintain a stable cutting depth; at the same time, the circumferential support also gives the wood additional constraint in the Z direction (thickness direction), reducing tool deflection and springback, and dimensional error and surface roughness decrease simultaneously.

[0015] Second, the first hydraulic rod retracts due to the reaction force, automatically transferring the pressure to the second hydraulic rod. The clamping force adapts to the size and hardness of the wood. The rubber sheet disperses the contact stress, avoiding indentations and accommodating slight shape errors.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model. Example

[0019] See Figures 1-4 This embodiment provides a quick positioning and clamping device for wood, including a base 1, a fixing mechanism 2 mounted on the top of the base 1, and a groove 3 provided on the top of the base 1; The fixing mechanism 2 includes a bidirectional threaded rod 24, which is rotatably connected to the inner wall of the base 1 via a bearing. A moving block 21 is threadedly connected to the outer wall of the bidirectional threaded rod 24. A fixing block 22 is fixedly connected to the side of the moving block 21. A clamping plate 23 is mounted on the side of the fixing block 22. An installation groove 210 is opened on the side of the clamping plate 23. A second hydraulic chamber 211 is mounted on the inner wall of the installation groove 210. A second hydraulic rod 213 is slidably connected to one end of the second hydraulic chamber 211. A gripper 212 is fixedly connected to the front of the second hydraulic rod 213. A power assembly for driving the moving block 21 and the gripper 212 is mounted on the top of the base 1.

[0020] The power assembly includes a motor 25, which is fixedly connected to the side of the base 1. A bidirectional threaded rod 24 extends movably through the base 1 to the side, and the extended end of the bidirectional threaded rod 24 is fixedly connected to the output end of the motor 25.

[0021] The inner walls of the movable block 21 and the fixed block 22 are fixedly connected to a first hydraulic chamber 216. Inside the first hydraulic chamber 216, a piston is slidably connected to a first hydraulic rod 26. The side of the first hydraulic rod 26 is fixedly connected to the side of the clamping plate 23. A spring 27 is movably sleeved on the outer wall of the first hydraulic rod 26.

[0022] A connecting hose 215 is fixedly connected to the side of the first hydraulic chamber 216, and the end of the connecting hose 215 away from the first hydraulic chamber 216 is fixedly connected to the side of the second hydraulic chamber 211.

[0023] The two ends of the spring 27 are fixedly connected to the side of the first hydraulic chamber 216 and the side of the clamping plate 23, respectively.

[0024] The base 1 has a limiting groove 28 at the top, and the clamping plate 23 has a slide plate 29 fixedly connected to the bottom. The slide plate 29 is slidably connected to the inner wall of the limiting groove 28.

[0025] The gripper 212 has a rubber sheet 214 fixedly connected to its side to increase friction with the wood.

[0026] In practical use, the above-mentioned equipment is activated by starting the motor 25, which drives the bidirectional threaded rod 24 to rotate. The bidirectional threaded rod 24 drives the moving block 21 to move to the right, which in turn drives the first hydraulic chamber 216 to move to the right. The first hydraulic chamber 216 drives the first hydraulic rod 26 to move to the right, which in turn drives the clamping plate 23 to move to the right. The clamping plate 23 slides on the inner wall of the limiting groove 28 via the sliding plate 29. When the clamping plate 23 contacts both sides of the wood, the reaction force causes the first hydraulic rod 26 to move to the left, compressing the spring 27. During the movement of the first hydraulic rod 26 to the left, the internal pressure of the first hydraulic chamber 216, the second hydraulic chamber 211, and the connecting hose 215 increases, causing the second hydraulic rod 213 to move forward. The second hydraulic rod 213 drives the gripper 212 and the rubber sheet 214 to fix the outer wall of the wood. When the second hydraulic rod 213 moves into position, the corresponding first hydraulic rod 26 also moves into position, thus fixing the sides and outer wall of the wood.
