Description

Technical Field

[0001] This application relates to the field of woodworking tools, and more specifically, to a multi-directional wood cutting guide with a positioning scale. Background Technology

[0002] Multi-directional cutting is extremely common in wood processing. From the diverse cutting of various boards in furniture manufacturing to the multi-angle cutting of wood joists and timber in building decoration, precise multi-directional cutting technology is indispensable.

[0003] When performing multi-directional cutting, the adjustment of the cutting angle often relies on the operator's experience and manual measurement, which is cumbersome and prone to errors. Conventional cutting guides have limited functions and can only guide straight cutting. They are difficult to meet the special angle cutting requirements such as 45-degree bevel cutting and mortise and tenon structures.

[0004] To address the aforementioned issues, this application provides a multi-directional wood cutting guide with a positioning scale. Utility Model Content

[0005] The multi-directional wood cutting guide plate with positioning scale provided in this application adopts the following technical solution:

[0006] A multi-directional wood cutting guide with a positioning ruler includes a guide plate body. A mounting groove is formed on the side of the guide plate body, into which a ruler is inserted. A positioning knob is threaded onto the top surface of the guide plate body, with one end of the knob abutting against the ruler. A cutting platform is located below the guide plate body, and a groove is formed on the top surface of the cutting platform. A transmission housing is fixed in the groove by screws, and a screw is rotatably mounted inside the transmission housing via a bearing. An adjustment knob connected to the screw is located at the end of the transmission housing. A threaded sleeve is threaded onto the surface of the screw, and a protrusion is fixed to the top of the threaded sleeve. A positioning groove is formed on the top surface of the protrusion, and several positioning notches are formed around the inner side of the positioning groove. A positioning post is welded to the end of the guide plate body near the transmission housing, and a positioning protrusion is welded to the lower surface of the positioning post corresponding to the positioning notches. A magnet is embedded at the end of the guide plate body away from the positioning post, and the magnet is attracted and connected to the top surface of the cutting platform.

[0007] The above technical solution meets the requirements for multi-directional cutting guidance of wood.

[0008] Furthermore, a strip-shaped opening is provided at the edge of the top surface of the guide plate body, which is connected to the mounting groove, and the strip-shaped opening corresponds to the scale of the ruler.

[0009] The above technical solution makes it easy to observe the ruler's markings, which is beneficial for measuring the cutting length of wood.

[0010] Furthermore, the length of the transmission housing is less than the length of the space inside the groove, and the top surface of the transmission housing has a strip-shaped clearance opening corresponding to the protrusion.

[0011] The above technical solution satisfies the requirements for installing the transmission housing and adjusting the knob rotation.

[0012] Furthermore, the positioning post of the guide plate body is inserted into the positioning groove, and two positioning protrusions are welded on the positioning post, and both positioning protrusions extend into two positioning notches of the positioning groove.

[0013] The above technical solution enables rapid locking of the guide plate body after any angle adjustment.

[0014] Furthermore, the top surfaces of the transmission housing and the protrusion are both on the same plane, and the bottom surface of the guide plate body is in contact with the top surface of the transmission housing.

[0015] The above technical solution maintains the fit between the guide plate body and the cutting platform.

[0016] Furthermore, two positioning knobs are threadedly installed on the top surface of the guide plate body, and both positioning knobs abut against the top surface of the ruler.

[0017] The ruler can be locked using the above technical solution.

[0018] Furthermore, the threaded sleeve has an overall square structure, and the bottom of the threaded sleeve is in contact with the inner bottom surface of the transmission housing.

[0019] The above technical solution prevents the threaded sleeve from shaking during its movement along the screw surface.

[0020] In summary, this application includes the following beneficial technical effects:

[0021] By engaging the positioning protrusions of the positioning posts with the positioning notches within the positioning grooves, the posts can be directly inserted into the notches corresponding to preset angles, achieving mechanical positioning. This structure eliminates the need for repeated manual measurements, controlling angular errors within mechanical tolerances. It allows for rapid switching between various cutting angles, solving the problems of traditional methods that rely on experience and have large errors. Combined with length positioning using a ruler, it can perform straight cuts, 45° bevel cuts, and mortise and tenon cuts at any angle, covering diverse needs in furniture making, decoration, and other scenarios. It breaks through the limitations of traditional guide plates that are "single-function." At the same time, the insertion of the positioning posts and positioning grooves restricts rotation, and the magnets adsorb the cutting platform to prevent translation, ensuring that the main body of the guide plate remains stationary during cutting.

[0031] Example:

[0032] This application discloses a multi-directional wood cutting guide plate with a positioning scale. Please refer to [link / reference]. Figure 1 , Figure 2 , Figure 3 and Figure 4A multi-directional wood cutting guide plate with a positioning ruler includes a guide plate body 1. A mounting groove 13 is provided on the side of the guide plate body 1, and a ruler 7 is inserted into the mounting groove 13. A positioning knob 8 is threaded onto the top surface of the guide plate body 1, with one end of the positioning knob 8 abutting against the ruler 7. A cutting platform 2 is provided below the guide plate body 1, and a groove 3 is provided on the top surface of the cutting platform 2. A transmission housing 4 is fixed in the groove 3 by screws, and a screw 5 is rotatably mounted inside the transmission housing 4 via a bearing. An adjustment knob 6 connected to the screw 5 is provided at the end of the transmission housing 4. A threaded sleeve 9 is installed on the surface threadedly, and a protrusion 11 is fixed at the top of the threaded sleeve 9. A positioning groove 14 is opened on the top surface of the protrusion 11, and several positioning notches 15 are opened around the inner side of the positioning groove 14. A positioning post 10 is welded to the end of the guide plate body 1 near the transmission housing 4, and a positioning protrusion 16 is welded to the lower surface of the positioning post 10 corresponding to the positioning notch 15. A magnet 12 is embedded and installed at the end of the guide plate body 1 away from the positioning post 10, and the magnet 12 is attracted and connected to the top surface of the cutting platform 2. The ruler 7 adopts a high-precision scale design, which can provide accurate reference for cutting dimensions. A positioning knob 8 is installed on the top surface of the guide plate body 1 by thread. After the ruler 7 is adjusted to the appropriate position in the mounting groove 13, the positioning knob 8 is tightened, and one end of it will be tightly abutted against the ruler 7, thereby firmly fixing the ruler 7 and preventing the ruler 7 from shifting due to vibration and other factors during the cutting process, thus ensuring measurement accuracy. A groove 3 is opened on the top surface of the cutting platform 2, which provides installation space for transmission-related components. A transmission housing 4 is fixed inside the groove 3 by screws, ensuring that the transmission housing 4 will not loosen during the cutting process. Inside the transmission housing 4, a screw 5 is rotatably mounted via bearings. The bearings ensure smoother rotation of the screw 5 and reduce wear caused by friction. An adjustment knob 6 is located at the end of the transmission housing 4, connected to the screw 5. When the operator rotates the adjustment knob 6, the screw 5 rotates synchronously. As the screw 5 rotates, the threaded sleeve 9 moves along the axial direction of the screw 5. A protrusion 11 is fixed to the top of the threaded sleeve 9, and the protrusion 11 moves together with the threaded sleeve 9. A positioning groove 14 is formed on the top surface of the protrusion 11. A positioning post 10 is welded to the end of the guide plate body 1 near the transmission housing 4. The positioning post 10 can be inserted into the positioning groove 14 to achieve initial positioning of the guide plate body 1 and the protrusion 11. The inner side of the positioning groove 14 is provided with several positioning notches 15. The lower surface of the positioning post 10 is welded with positioning protrusions 16 corresponding to the positioning notches 15. When the positioning post 10 is inserted into the positioning groove 14, the positioning protrusions 16 will engage with the corresponding positioning notches 15, thereby restricting the rotation of the guide plate body 1 and achieving angular positioning. A magnet 12 is embedded in the end of the guide plate body 1 away from the positioning post 10. The magnet 12 is attracted to the top surface of the cutting platform 2. This attraction connection method can fix the end of the guide plate body 1 away from the positioning post 10. Combined with the connection between the positioning post 10 and the protrusion 11, the guide plate body 1 remains stable on the cutting platform 2, preventing shaking during cutting.

[0033] Please see Figure 2 and Figure 3 The top edge of the guide plate body 1 has a strip-shaped opening that communicates with the mounting groove 13, and the strip-shaped opening corresponds to the scale of the ruler 7. Since the ruler 7 is installed in the mounting groove 13, if its scale is obscured by the guide plate body 1, the operator will not be able to read the scale. However, the strip-shaped opening, corresponding to the scale of the ruler 7, allows the scale of the ruler 7 to be clearly exposed through the strip-shaped opening. When adjusting the position of the ruler 7 or performing cutting positioning, the operator can directly observe the scale value on the ruler 7 through the strip-shaped opening.

[0034] Please see Figure 2 and Figure 3 The length of the transmission housing 4 is less than the length of the inner space of the groove 3, and the top surface of the transmission housing 4 has a strip-shaped clearance opening corresponding to the protrusion 11. This design provides space for the installation of the transmission housing 4 in the groove 3 and for possible subsequent adjustments. In the actual assembly process, there may be some dimensional errors. The smaller length of the transmission housing 4 can avoid the problem of installation failure due to size mismatch. The strip-shaped clearance opening on the top surface of the transmission housing 4 allows the protrusion 11 to pass through the top surface of the transmission housing 4 when the threaded sleeve 9 drives the protrusion 11 to move along the screw 5. The strip-shaped clearance opening provides a channel for the movement of the protrusion 11, avoiding obstruction of the movement of the protrusion 11 by the transmission housing 4. Moreover, the length of the strip-shaped clearance opening is adapted to the range of movement of the protrusion 11, ensuring that the protrusion 11 can pass smoothly throughout the entire movement process without being interfered with by the transmission housing 4, and ensuring that the position adjustment of the guide plate body 1 can be carried out smoothly.

[0035] Please see Figure 2 and Figure 3The positioning post 10 of the guide plate body 1 is inserted into the positioning groove 14. Two positioning protrusions 16 are welded onto the positioning post 10, and both protrusions 16 extend into two positioning notches 15 of the positioning groove 14. This insertion structure is key to the connection between the guide plate body 1 and the protrusion 11. After the positioning post 10 is inserted into the positioning groove 14, it can limit the horizontal movement of the guide plate body 1, preventing large displacement in the horizontal direction. The design of two positioning protrusions 16 further enhances the positioning effect compared to a single positioning protrusion 16. A single positioning protrusion 16 may detach from the positioning notch 15 due to uneven force. However, when two positioning protrusions 16 simultaneously engage with the positioning notch 15, the positioning post 10 is more securely fixed within the positioning groove 14. The positioning notches 15 are formed around the inner side of the positioning groove 14, with several notches 15 corresponding to different angles. When it is necessary to adjust the angle of the guide plate body 1, simply pull the positioning post 10 out of the positioning groove 14, rotate the guide plate body 1 to the desired angle, and then engage the positioning protrusion 16 with the corresponding positioning notch 15. The two positioning protrusions 16 engaging with the two positioning notches 15 respectively can accurately determine the angular position of the guide plate body 1, ensuring the accuracy of angle positioning and meeting the requirements of multi-directional cutting for different angles.

[0036] Please see Figure 2 and Figure 3 The top surfaces of the transmission housing 4 and the protrusion 11 are both on the same plane, and the bottom surface of the guide plate body 1 is in contact with the top surface of the transmission housing 4. This design ensures the flatness of the guide plate body 1 when placed. If the top surfaces of the transmission housing 4 and the protrusion 11 are not on the same plane, the bottom surface of the guide plate body 1 will be uneven when in contact with them, causing the guide plate body 1 to tilt. The close contact between the bottom surface of the guide plate body 1 and the top surface of the transmission housing 4 increases the friction between them, further preventing the guide plate body 1 from shifting during the cutting process. At the same time, the flat contact surface makes the supporting force on the guide plate body 1 more uniform, avoiding deformation of the guide plate body 1 due to excessive local stress, ensuring the structural stability of the guide plate body 1 during long-term use, and providing a reliable foundation for cutting guidance.

[0037] Please see Figure 2 and Figure 3 Two positioning knobs 8 are threadedly installed on the top surface of the guide plate body 1, and both positioning knobs 8 abut against the top surface of the ruler 7. Compared with a single positioning knob 8, two positioning knobs 8 can fix the ruler 7 from different positions. A single positioning knob 8 may only apply pressure to the ruler 7 at one point, which may easily lead to uneven force on the ruler 7 and cause it to tilt.

[0038] Please see Figure 2 and Figure 3 The threaded sleeve 9 has a square structure, and its bottom contacts the inner bottom surface of the transmission housing 4. During the movement of the threaded sleeve 9, the bottom contact reduces the shaking of the threaded sleeve 9, making its movement more stable. At the same time, this contact method can also distribute the pressure on the threaded sleeve 9, avoid damage to the threaded sleeve 9 due to concentrated force, extend its service life, and ensure that the position adjustment of the guide plate body 1 can be carried out stably for a long time.

[0039] The implementation principle of this embodiment is as follows: In use: the strip opening on the top surface of the guide plate body 1 corresponds to the scale of the ruler 7, allowing for real-time display of the current scale value, facilitating quick determination of the cutting length. When the wood is placed on the cutting platform 2, the ruler 7 is inserted into the mounting groove 13 of the guide plate body 1, and the scale of the ruler 7 can be directly observed through the strip opening on the top surface of the guide plate. According to the required cutting length, slide the ruler 7 to the corresponding scale, and tighten the two positioning knobs 8, with the ends of the knobs abutting against the ruler 7 and fixing its position. At this time, the wood is in contact with the side of the guide plate body 1, and the cutting starting point can be determined with the end of the ruler 7 as a reference, achieving precise positioning in the length direction. When the cutting angle needs to be adjusted, lift the guide plate body 1 to disengage the positioning post 10 from the positioning groove 14 of the protrusion 11, rotate the guide plate to the target angle, and then reinsert the positioning post 10 into the positioning groove 14, so that the positioning protrusion 16 engages with the positioning notch 15 of the corresponding angle. Positioning notches 15 are distributed around positioning grooves 14, each notch corresponding to a fixed angle. Mechanical locking restricts the rotation of the guide plate, achieving angle locking. To adjust the cutting position at a fixed angle (e.g., shifting the guide plate to change the cutting starting point), rotating the adjustment knob 6 rotates the screw 5. The square threaded sleeve 9 on the surface of the screw 5, unable to rotate with the screw 5 (restricted by the inner wall of the transmission housing 4), shifts axially along the screw 5. The top protrusion 11 moves synchronously with the threaded sleeve 9, thereby shifting the guide plate body 1 through the positioning groove 14. The strip-shaped clearance opening of the transmission housing 4 provides space for the movement of the protrusion 11, ensuring smooth adjustment. The insertion of the positioning post 10 into the positioning groove 14 restricts horizontal rotation, and the magnet 12 at the other end of the guide plate adheres to the top surface of the cutting platform 2 to prevent shifting. The wood is placed against the side of the guide plate body 1 and slides along the guide plate during cutting. With double fixation, the guide plate remains stationary, ultimately achieving precise multi-directional cutting. This transforms human error into controllable mechanical precision, ultimately achieving precise guidance for multi-directional cutting.

[0040] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
