Description

Technical Field

[0001] This utility model relates to the field of bench saw blade technology, specifically a bench saw blade parallel calibration device. Background Technology

[0002] A table saw blade is a key component used with a table saw (also known as a bench saw) for cutting operations. The table saw blade is the cutting part of the table saw, typically made of carbide or other wear-resistant materials, with a sharp cutting edge and a specific thickness and diameter. It is used to cut various materials such as wood, metal, plastic, and tile. Parallel alignment of the table saw blade is crucial.

[0003] When replacing the saw blade, some table saws typically use a right-angle ruler to adjust the blade angle. This not only makes the saw blade more stable when rotating but also ensures more accurate dimensions after cutting. Therefore, a right-angle ruler is a key tool used with table saws.

[0004] Most existing right-angle ruler calibration devices require manual contact between the operator and the saw blade, which results in poor stability and a tendency to tip over. When the saw blade shifts position, the operator needs to adjust it, which makes the device prone to tipping over if it cannot be manually controlled. This not only affects the operator's ability to adjust the angle of the saw blade but also reduces the efficiency of the adjustment.

[0005] Meanwhile, most existing devices cannot adjust their own height, which leads to large errors in the angle adjustment of saw blades when calibrating them with larger radii due to insufficient device height. This not only affects the accuracy of the saw blade position but also reduces the applicability of the device. Utility Model Content

[0006] The purpose of this invention is to provide a table saw blade parallel calibration device to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a table saw blade parallel calibration device, including a base and a calibration plate fixed to one side of its top, and further comprising:

[0008] A mounting groove is formed at the bottom of the base. A threaded rod is provided in the inner cavity of the mounting groove. A suction cup is installed at the bottom of the threaded rod. A pressing plate is fixedly connected to the surface of the threaded rod. Movable mechanisms are installed on both sides of the inner cavity of the mounting groove.

[0009] A fixed plate slides within the cavity of the calibration plate. Both the fixed plate and the calibration plate have scale lines on their surfaces. A locking plate is fixedly connected to one side of the fixed plate, and a bolt is provided on one side of the calibration plate. The other end of the bolt is rotatably connected to a positioning plate.

[0010] Preferably, the movable mechanism includes a movable block that slides on the inner wall of the mounting groove and a connecting plate fixed to one side thereon, and also includes a movable cone fixed below one side of the connecting plate and a compression spring fixed to one side of the connecting plate.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0016] This invention utilizes the cooperation of a threaded rod and a suction cup to fix the device to the tabletop, thereby improving its stability during use and making it easier for operators to adjust the saw blade angle.

[0022] 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.

[0023] Please see Figure 1-4As shown, the table saw blade parallel calibration device includes a base 1. A calibration plate 2 is fixedly connected to one side of the top of the base 1. The angle between the base 1 and the calibration plate 2 is designed to be 90 degrees. Under this design, the saw blade can be placed on a table, with one side of the calibration plate 2 in contact with the saw blade, thereby calibrating the parallel angle of the saw blade. The bottom of the base 1 has a mounting groove 3, and the inner cavity of the mounting groove 3 is provided with a threaded rod 4. The top of the threaded rod 4 passes through to the outside of the base 1 and is threadedly connected to the inner wall of the through-hole. A suction cup 5 is installed at the bottom of the threaded rod 4. Under this design, the suction cup 5 can be squeezed by rotating the threaded rod 4, so that the device can be attached to the table by the cooperation of the suction cup 5. This eliminates the need for the operator to constantly adjust the saw blade. This device features a limiting mechanism, effectively improving its stability during use and preventing instability from affecting the operator's adjustment of the saw blade. A pressing disc 6 is fixedly connected to the surface of the threaded rod 4. Movable mechanisms 7 are installed on both sides of the inner cavity of the mounting groove 3. When the threaded rod 4 rotates, it can move the pressing disc 6, thereby changing the position of the movable mechanisms 7. This prevents the movable mechanisms 7 from interfering with the connection between the suction cup 5 and the table. When it is necessary to disconnect the suction cup 5 from the table, rotating the threaded rod 4 removes the pressing disc 6 from contact with the movable mechanisms 7. The movable mechanisms 7 disrupt the negative pressure inside the suction cup 5, making it easier to release the limiting mechanism and effectively improving the device's performance. For applicability, a guide plate 13 is rotatably connected to the bottom of the threaded rod 4. Guide grooves 14 are provided on both sides of the inner wall of the mounting groove 3. The surface of the guide plate 13 is slidably connected to the surface of the guide groove 14. The bottom of the guide plate 13 is fixedly connected to the top of the suction cup 5. Under this action, the guide plate 13 can be moved when the threaded rod 4 rotates. With the cooperation of the guide plate 13 and the guide groove 14, the suction cup 5 can be limited, so that the suction cup 5 will not rotate arbitrarily when moving. This makes the suction cup 5 more stable when in contact with the table, and avoids the suction cup 5 rotating and affecting the connection with the table. A fixing plate 8 is slidably connected to the inner cavity of the calibration plate 2. The surface of the fixing plate 8 and the cross-sectional shape of the inner cavity of the calibration plate 2 are both T-shaped structures. The fixing plate 8 and the calibration plate 2 are matched. When used together, the fixed plate 8 is limited by its shape, preventing it from shifting during movement and effectively improving its limiting effect. Both the fixed plate 8 and the calibration plate 2 have scale lines 9 on their surfaces, facilitating operation and enhancing the device's versatility. A locking plate 10 is fixedly connected to one side of the fixed plate 8; the locking plate 10 has a flexible structure. A bolt 11 is provided on one side of the calibration plate 2, with one end penetrating into the calibration plate 2 and threaded to its inner wall. The other end of the bolt 11 is rotatably connected to a positioning plate 12, which is made of rubber. The positioning plate 12 works in conjunction with the locking plate 10.Under this action, after the fixing plate 8 is moved to a suitable position, the positioning plate 12 can be pressed against one side of the locking plate 10 by rotating the bolt 11, thereby increasing the friction between the fixing plate 8 and the inner wall of the calibration plate 2, thus achieving the effect of limiting the fixing plate 8.

[0024] The movable mechanism 7 includes a movable block 71 that slides along the inner wall of the mounting groove 3. One side of the movable block 71 has an inclined structure design, and the surface of the movable block 71 is slidably connected to the surface of the extrusion plate 6. Under this action, the movable block 71 can be extruded when the extrusion plate 6 moves, thereby causing the movable block 71 to shift its position. A connecting plate 72 is fixedly connected to one side of the movable block 71, and a movable cone 73 is fixedly connected to the lower side of one side of the connecting plate 72. The movable cone 73 is used in conjunction with the suction cup 5. A compression spring 74 is fixedly connected to one side of the connecting plate 72, and the other end of the compression spring 74 is fixedly connected to the inner wall of the mounting groove 3. Under this action, when the extrusion plate 6 extrudes the movable block 71, the connecting plate 72 can drive the movable cone 73 to move, preventing the movable cone 73 from affecting the contact between the suction cup 5 and the table. When the extrusion plate 6 stops extruding the movable block 71, the movable cone 73 can return to its original position with the cooperation of the compression spring 74, thereby releasing the negative pressure state inside the suction cup 5 and disconnecting the suction cup 5 from the table, making it convenient for the device to move.

[0025] It is worth noting that the technical features such as the base 1 and calibration plate 2 proposed in this technical solution should be regarded as prior art. The specific structure, working principle and possible control methods and spatial arrangement of these technical features can be selected using conventional methods in this field. This technical solution will not elaborate further.

[0026] Working principle: First, place the device on the table. Then, align one side of the calibration plate 2 with the saw blade. Next, rotate the threaded rod 4. Under the action of the threaded rod 4, the pressing plate 6 will move. When the pressing plate 6 presses the movable block 71, the moving cone 73 can move through the cooperation of the connecting plate 72, preventing it from affecting the movement of the suction cup 5. When the threaded rod 4 moves, it will cause the suction cup 5 to press against the table, thus creating a negative pressure inside the suction cup 5, which prevents the device from moving easily. With the cooperation of the guide plate 13 and the guide groove 14, the device will not easily shake, effectively improving the stability of the device. Then, adjust the saw blade according to the calibration plate 2. When the radius of the saw blade is greater than the length of the calibration plate 2, rotate the bolt 11 to move the positioning plate 12 to release the pressure on the fixed plate 8. Then move the fixed plate 8 to the appropriate position. Then, rotate the bolt 11 again to limit the fixed plate 8 through the positioning plate 12.
