Description

Technical Field

[0001] This application relates to the field of wood processing technology, and in particular to an adjustable-size wood board cutting and positioning device. Background Technology

[0002] In the furniture manufacturing process, the first step is to cut the long planks. Existing plank cutting machines have two working modes. One mode is to fix the plank to be cut, cut a portion, and then fix it again for the next cut. Only one plank can be cut at a time, which is extremely inefficient. The other mode is for the worker to manually push the plank forward for cutting. If the worker does not operate it properly, there will be certain safety hazards.

[0003] Regarding the aforementioned technologies, the inventors believe the following problems still exist: Firstly, some existing wood processing equipment typically moves the wood to change its position relative to the saw blade for cutting. However, this method may cause the wood to shift during movement, resulting in dimensional deviations and reducing the subsequent processing effect.

[0004] Secondly, when cutting wood, the wood may warp due to the impact of the saw blade. This not only makes the wood prone to deviation, resulting in lower cutting accuracy, but may also cause it to fall off and injure people, thus resulting in poor cutting effect.

[0005] To address the aforementioned problems, the inventors have proposed an adjustable-size wooden board cutting and positioning device to solve these issues. Utility Model Content

[0006] In order to improve the problem that some existing devices do not work well in certain situations, the purpose of this utility model is to provide an adjustable size wood cutting and positioning device.

[0007] To solve the above problems, this utility model provides the following solution: an adjustable-size wood cutting and positioning device, including a cutting table, a cutting machine body on the upper part of the cutting table, a first positioning mechanism and a second positioning mechanism on the top surface of the cutting table, a fixing mechanism on the top surface of the first positioning mechanism, the first positioning mechanism including two slide rails distributed on both sides of the top surface of the cutting table, a slider slidably mounted on the top surface of each of the two slide rails, a fixing plate fixedly mounted between the two sliders, a positioning baffle fixedly mounted on one side of the fixing plate, a positioning bolt threaded into one side of the slider, the end of the positioning bolt abutting against the outer surface of the slide rail, a scale fixedly mounted on one side of the top surface of the cutting table, and a pointer fixedly mounted on one side of the positioning baffle, the pointer abutting against the surface of the scale. Preferably, the second positioning mechanism includes a support plate, which is fixedly installed on one side of the top surface of the cutting table. A lead screw is threaded into the middle of the support plate, and a connecting plate is rotatably installed at one end of the lead screw. A positioning block is fixedly installed on the side of the connecting plate opposite to the lead screw, and the positioning block is in contact with the top surface of the cutting table. Two limiting rods are fixedly installed on the side of the connecting plate where the lead screw is installed, and the ends of the two limiting rods away from the connecting plate are movably inserted into the middle of the support plate. Preferably, the fixing mechanism includes a support frame, which is fixedly installed on one side of the top surface of the fixing plate. A mini cylinder is fixedly installed on the top surface of the support frame, and the telescopic end of the mini cylinder movably passes through the support frame and is fixedly installed with a rubber block. Compared with the prior art, the beneficial effects of this utility model are as follows: 1. This utility model, by setting a first positioning mechanism and a second positioning mechanism, can position the wooden board in two directions through the cooperation of the first positioning mechanism and the second positioning mechanism, thereby preventing it from moving and making the subsequent cutting more accurate and improving the cutting effect.

[0008] 2. This utility model, by setting a fixing mechanism, can fix the wooden board vertically and prevent the wood from warping on one side due to impact. This prevents the wooden board from moving or falling off during cutting operations, thus improving the safety of cutting operations. Attached Figure Description

[0017] 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.

[0018] Example: Figure 1-6 As shown, this utility model provides an adjustable-size wood cutting and positioning device, including a cutting table 1. The cutting table 1 serves as a support, supporting some components of the device to prevent them from falling off. A cutting machine body 11 is provided on the upper part of the cutting table 1. The cutting machine body 11 is a prior art device used to cut wood. A sliding groove 12 is provided on one side of the top surface of the cutting table 1. The sliding groove 12 is a through groove. The cutting machine body 11 is slidably installed inside the sliding groove 12, so that while the cutting machine body 11 rotates, it moves through the sliding groove 12, thereby moving relative to the wood board.

[0019] The top surface of the cutting table 1 is provided with a first positioning mechanism 2 and a second positioning mechanism 3. The first positioning mechanism 2 and the second positioning mechanism 3 are positioning components. They work together to position the wood. The top surface of the first positioning mechanism 2 is provided with a fixing mechanism 4. The fixing mechanism 4 can move together with the first positioning mechanism 2 to fix the wood board and prevent the wood board from moving during the cutting process.

[0020] The first positioning mechanism 2 includes two slide rails 21. As existing technology, the slide rails 21 can drive the sliders 23 to move. The two slide rails 21 are distributed on both sides of the top surface of the cutting table 1 to prevent them from falling off. The two slide rails 21 are parallel to each other on both sides of the top surface of the cutting table 1, allowing them to synchronously drive the two sliders 23 to move. Sliding sliders 23 are slidably mounted on the top surface of each slide rail 21. The sliders 23 can cooperate with the slide rails 21 to slide on the top surface of the slide rails 21. A fixed plate 24 is fixedly installed between the two sliders 23, so that the two synchronously moving sliders 23 drive the fixed plate 24 to move, thereby allowing the fixed plate 24 to move on the top surface of the cutting table 1. A positioning baffle 25 is fixedly installed on one side of the fixed plate 24. As a plate structure, the positioning baffle 25 can be moved by the movement of the fixed plate 24, thereby positioning the wooden board. The positioning baffle 25 is located on the side of the fixed plate 24 close to the cutting machine body 11, so that it can position the wooden board.

[0021] A positioning bolt 22 is threaded into one side of the slider 23. The positioning bolt 22 is threaded and can be rotated to rotate on one side of the slider 23. The end of the positioning bolt 22 is in contact with the outer surface of the slide rail 21. Rotating the positioning bolt 22 increases the friction with the slide rail 21, thereby fixing the slider 23 and preventing it from moving. A scale 26 is fixedly installed on one side of the top surface of the cutting table 1. As a prior art, the scale 26 can be used to count the position of the slider 23 and the positioning baffle 25, thereby improving the positioning effect of the wooden board. A pointer 27 is fixedly installed on one side of the positioning baffle 25. The pointer 27 is in contact with the surface of the scale 26. The pointer 27 and the scale 26 are used together, and the pointer 27 can slide on the outer surface of the scale 26.

[0022] The second positioning mechanism 3 includes a support plate 35, which is a vertical plate structure that supports some components of the second positioning mechanism 3. The support plate 35 is fixedly installed on one side of the top surface of the cutting table 1. The support plate 35 can prevent the support plate 35 from falling off, thus supporting other components. A lead screw 33 is threaded into the middle of the support plate 35. As prior art, the lead screw 33 can move the positioning block 31 by rotating it. A connecting plate 34 is rotatably installed at one end of the lead screw 33. The connecting plate 34 serves as a connector, connecting the lead screw 33 and the positioning block 31. A handwheel 36 is fixedly installed at the end of the lead screw 33 away from the connecting plate 34. Rotating the handwheel 36 can rotate the lead screw 33. The side of the connecting plate 34 facing away from the lead screw 33 is fixedly installed... The machine is equipped with a positioning block 31, with a rubber pad on one side for positioning the wooden board. The positioning block 31 is located on one side of the cutting machine body 11, allowing it to position the wooden board within the working range of the cutting machine body 11. The positioning block 31 is in contact with the top surface of the cutting table 1, allowing it to slide on the top surface of the cutting table 1, thus preventing it from shifting. Two limiting rods 32 are fixedly installed on one side of the connecting plate 34 where the screw 33 is mounted. As prior art, the limiting rods 32 can limit the connecting plate 34, thus preventing it from tilting or rotating. The ends of the two limiting rods 32 away from the connecting plate 34 are movably inserted into the middle of the support plate 35, allowing the limiting rods 32 to slide in the middle of the support plate 35, thereby adapting to the movement of the connecting plate 34.

[0023] The fixing mechanism 4 includes a support frame 42, which serves as a support component. The support frame 42 is fixedly installed on one side of the top surface of the fixing plate 24 to prevent it from moving. The cross-section of the support frame 42 is L-shaped. The support frame 42 can support and fix the mini cylinder 41. At the same time, the position of the mini cylinder 41 can extend outward. The mini cylinder 41 is fixedly installed on the top surface of the support frame 42. As prior art, the mini cylinder 41 can drive the rubber block 43 to move, thereby fixing the wooden board. The telescopic end of the mini cylinder 41 moves through the support frame 42 and is fixedly installed with the rubber block 43. As prior art, the rubber block 43 can compress and fix the wooden board while preventing damage to the wooden board, thus improving practicality. The rubber block 43 is located on the side of the fixing plate 24 near the cutting machine body 11, so that the rubber block 43 is above one side of the positioning baffle 25, thereby fixing the wooden board on one side of the positioning baffle 25.

[0024] Working principle: First, fix the cutting table 1 of this device in a suitable position to prevent it from moving. Then, slide the fixing plate 24 to move the slider 23. The slider 23 moves through the slide rail 21, thereby moving the fixing plate 24. The fixing plate 24 moves the positioning baffle 25. The positioning baffle 25 slides on the outer surface of the scale 26 through the pointer 27 on one side. When adjusted to the specified position, the positioning bolt 22 can be rotated to lock the slider 23 and fix it.

[0025] Then, turn the handwheel 36 to drive the lead screw 33 to rotate. The lead screw 33 rotates inside the support plate 35 and drives the connecting plate 34 to move. At the same time, the connecting plate 34 moves through the two limit rods 32, thereby limiting the connecting plate 34 to move linearly and driving the positioning block 31 to move.

[0026] After adjusting the first positioning mechanism 2 and the second positioning mechanism 3 to the appropriate positions, place the wooden board on the top surface of the cutting table 1, with one side of it in contact with the positioning baffle 25 and the other side in contact with the positioning block 31. Then, start the mini cylinder 41 on the top surface of the support frame 42, so that the mini cylinder 41 drives the rubber block 43 to descend, thereby squeezing and fixing the wooden board to prevent it from moving. Then, start the cutting machine body 11, so that the cutting machine body 11 rotates and moves at the same time, so that it moves through the slide groove 12 and cuts the wooden board.

[0027] Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
