Description

Technical Field

[0001] This utility model relates to the field of board cutting technology, specifically a precise positioning wooden cabinet board cutting device. Background Technology

[0002] Wooden cabinets are kitchen storage furniture made primarily of wood or wood composite materials, through processes such as cutting, assembly, and painting. During their production and processing, the boards need to be cut into specific sizes such as cabinet side panels, bottom panels, and shelves to ensure that the cabinets fit seamlessly with the walls and floors. Therefore, a cutting device is required.

[0003] A Chinese patent with authorization announcement number CN117359727A discloses a wood board cutting device for furniture processing, including a workbench and n-shaped boards symmetrically fixed to the top of the workbench, wherein a horizontal plate is fixed to one side of the n-shaped board, and an electric cutting disc is installed on the workbench. The invention first places the wood board on the workbench and contacts it with the push plate, then starts the electric cutting disc to move forward, driving the T-shaped rod to move forward, so that the pressure plate moves downward first to press and fix the wood board, and then the electric cutting disc continues to move forward to cut the pressed wood board. In this way, no additional operation is required to fix the wood board, thereby improving work efficiency.

[0004] However, the above-mentioned cutting device still has some problems. In practical applications, the lack of positioning plate position adjustment results in the ability to cut only one size of board, making it impossible to accurately control the cutting width of the board and meet the customization needs of cabinets. Therefore, a precise positioning wooden cabinet board cutting device is proposed to address the above problems. Utility Model Content

[0005] To overcome the shortcomings of existing technologies and solve the problems mentioned in the background art, this utility model proposes a precise positioning cutting device for wooden cabinet panels.

[0006] The technical solution adopted by this utility model to solve its technical problem is as follows: A precise positioning wooden cabinet board cutting device of this utility model includes a workbench. A sliding groove is formed at one end of the top side of the workbench. A sliding plate is slidably installed inside the sliding groove. A positioning plate is installed at one end of the top side of the sliding plate. A side groove is formed inside the sliding groove. A sliding strip is fixed to one side of the sliding plate and slidably installed inside the side groove. A rack is installed on the other side of the sliding plate. A servo motor is installed on the top side of the workbench. A connecting groove communicating with the sliding groove is formed inside the workbench. A rotating shaft is installed at the output end of the servo motor. The bottom end of the rotating shaft is rotatably installed inside the connecting groove. A gear is installed on the outside of the rotating shaft. The gear meshes with the rack. Several scale lines are equidistantly engraved on the top side of the workbench located on one side of the sliding groove. Driven by the servo motor, the sliding plate moves precisely within the sliding groove, thereby accurately adjusting the distance between the positioning plate and the cutting blade. This allows for quick and precise setting of the board cutting width, meeting the cutting needs of different board specifications and improving the flexibility and accuracy of the cutting operation.

[0007] Preferably, a drive motor is installed on one side of the workbench, and a bidirectional lead screw is installed at the output end of the drive motor. Two rectangular slots are symmetrically opened at the other end of the top side of the workbench. Fixed clamping plates are slidably installed inside the rectangular slots. Each fixed clamping plate has a screw hole inside. One end of the bidirectional lead screw passes through the screw hole and is rotatably installed inside the rectangular slot. When the drive motor is started, the bidirectional lead screw is driven to rotate, thereby adjusting the distance between the two fixed clamping plates, so that it can firmly clamp plates of different lengths and improve the stability of the plates during cutting operations.

[0008] Preferably, a fixed frame is installed at the top edge of the workbench, a reciprocating motor is installed on one side of the top of the fixed frame, a threaded rod is installed at the output end of the reciprocating motor, a through groove is opened inside the top side of the fixed frame, a sliding block is slidably installed inside the through groove, a threaded hole is opened inside the bottom end of the sliding block, one end of the threaded rod passes through the threaded hole and is rotatably installed inside the fixed frame. By controlling the rotation of the reciprocating motor, the position of the sliding block in the lateral direction can be precisely controlled, thereby driving the cylinder, cutting motor and cutting blade installed on its bottom side to move laterally together, so that the cutting blade can make lateral cuts on the surface of the plate.

[0009] Preferably, a cylinder is installed on the bottom side of the sliding block, a mounting bracket is installed on the working end of the cylinder, a cutting motor is installed on one side of the mounting bracket, a cutting blade is installed on the output end of the cutting motor, and a blade groove is opened through the inside of the worktable, the blade groove is located directly below the cutting blade, the cylinder drives the mounting bracket to descend, so that the cutting blade contacts the plate and cuts, and the blade groove can ensure that the plate is completely cut off.

[0010] Preferably, a support frame is installed on one side of the mounting bracket, and grooves are formed inside both sides of the support frame. A slider is slidably installed inside the groove, and a whetstone is installed between the sliders. A screw is rotatably installed inside one side of the whetstone, and one end of the screw extends through to the outside of the support frame and is equipped with a handle. By rotating the handle, the screw drives the whetstone to slide in the groove, so that it contacts the cutting blade for sharpening. This allows for timely sharpening of the cutting blade, maintaining its sharpness and extending its service life.

[0011] Preferably, a control panel is installed on one side of the workbench, and the control panel is electrically connected to the electrical components inside the device, thereby realizing centralized control of the electrical components inside the device.

[0012] The advantages of this utility model are:

[0013] 1. The present invention starts the servo motor, whose output shaft rotates, and the gear rotates accordingly. The rotation of the gear is converted into the linear motion of the rack, which drives the slide plate to slide in the slide groove. The positioning plate on the top of the slide plate moves synchronously with the slide plate. The operator can refer to the scale line on the top side of the workbench to intuitively determine the distance between the positioning plate and the cutting blade. The servo motor precisely controls the speed and number of rotations to achieve precise displacement of the positioning plate and meet the cutting width requirements of different materials.

[0014] 2. This utility model involves rotating the handle to drive the screw to rotate. The screw engages with the outer thread of the support frame, and the whetstone slides along the groove through the thread transmission, allowing the whetstone to contact the cutting blade. Once the whetstone and the cutting blade are in contact, the cutting motor drives the cutting blade to rotate at a low speed to perform the whetstone operation. The rotational cooperation between the whetstone and the cutting blade removes the worn parts of the blade, restores the sharpness of the cutting blade, extends the service life of the tool, and ensures the cutting quality.

Detailed Implementation

[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 scope of protection of the present utility model.

[0023] Please see Figure 1-4 As shown, a precise positioning wooden cabinet board cutting device includes a workbench 1. A groove 2 is provided at one end of the top side of the workbench 1. A slide plate 3 is slidably installed inside the groove 2. A positioning plate 4 is installed at one end of the top side of the slide plate 3. A side groove 5 is provided inside the groove 2. A slide bar 6 is fixed to one side of the slide plate 3 and is slidably installed inside the side groove 5. A rack 7 is installed on the other side of the slide plate 3. A servo motor 8 is installed on the top side of the workbench 1. A connecting groove 9 communicating with the groove 2 is provided inside the workbench 1. A rotating shaft 10 is installed at the output end of the servo motor 8. The bottom end of the rotating shaft 10 is rotatably installed inside the connecting groove 9. A gear 11 is installed on the outside of the rotating shaft 10. The gear 11 meshes with the rack 7. Several scale lines 12 are equidistantly engraved on the top side of the workbench 1, located on one side of the groove 2.

[0024] A drive motor 13 is installed on one side of the workbench 1. A bidirectional lead screw 14 is installed at the output end of the drive motor 13. Two rectangular slots 15 are symmetrically opened at the other end of the top side of the workbench 1. A fixed clamping plate 16 is slidably installed inside the rectangular slot 15. Each fixed clamping plate 16 has a screw hole inside. One end of the bidirectional lead screw 14 passes through the screw hole and is rotatably installed inside the rectangular slot 15.

[0025] A control panel 33 is installed on one side of the workbench 1. The control panel 33 is electrically connected to the electrical components inside the device. During operation, in practical applications, the lack of position adjustment of the positioning plate 4 results in the inability to cut only one size of board, making it impossible to accurately control the cutting width of the board and meet the customization needs of the cabinet. According to the required cutting width of the board, the servo motor 8 is started, and its output shaft 10 begins to rotate. The gear 11 on the outside of the shaft 10 rotates accordingly. Since the gear 11 meshes with the rack 7, the rotation of the gear 11 is converted into the linear motion of the rack 7, which drives the slide plate 3 to slide in the slide groove 2. The positioning plate 4 on the top of the slide plate 3 moves synchronously with the slide plate 3. The operator can refer to the scale line 12 on the top side of the workbench 1 to intuitively determine the distance between the positioning plate 4 and the cutting blade 25. The servo motor 8 accurately controls the speed and number of rotations to achieve precise displacement of the positioning plate 4 and meet the cutting width requirements of different boards.

[0026] After the positioning plate 4 is adjusted, the plate is placed between the two fixed clamping plates 16, with one side of the plate in contact with one side of the positioning plate 4. The drive motor 13 rotates the bidirectional lead screw 14 at its output end. Since the threads at both ends of the bidirectional lead screw 14 turn in opposite directions, and the two fixed clamping plates 16 are engaged with the bidirectional lead screw 14 through screw holes, when the bidirectional lead screw 14 rotates, the two fixed clamping plates 16 will move towards or away from each other along the rectangular groove 15. Adjusting the distance between the fixed clamping plates 16 ensures that plates of different lengths are firmly clamped, preventing the plates from shifting during cutting and affecting cutting accuracy and safety.

[0027] Please see Figure 1 , 2 As shown in Figure 5, a fixed frame 17 is installed at the top edge of the workbench 1. A reciprocating motor 18 is installed on one side of the top of the fixed frame 17. A threaded rod 19 is installed at the output end of the reciprocating motor 18. A through groove 20 is opened inside the top side of the fixed frame 17. A sliding block 21 is slidably installed inside the through groove 20. A threaded hole is opened inside the bottom end of the sliding block 21. One end of the threaded rod 19 passes through the threaded hole and is rotatably installed inside the fixed frame 17.

[0028] A cylinder 22 is mounted on the bottom side of the sliding block 21. A mounting bracket 23 is mounted on the working end of the cylinder 22. A cutting motor 24 is mounted on one side of the mounting bracket 23. A cutting blade 25 is mounted on the output end of the cutting motor 24. A blade groove 26 is opened through the inside of the worktable 1. The blade groove 26 is located directly below the cutting blade 25.

[0029] A support frame 27 is installed on one side of the mounting bracket 23. Grooves 28 are formed inside both sides of the support frame 27. Sliding sliders 29 are slidably installed inside the grooves 28. A whetstone 30 is installed between the sliding sliders 29. A screw 31 is rotatably installed inside one side of the whetstone 30. One end of the screw 31 extends through to the outside of the support frame 27 and is fitted with a handle 32. During operation, the wooden cabinet is kitchen storage furniture made primarily of wood or wood composite materials, processed through cutting, assembly, and painting. During its production, the boards need to be cut to specific dimensions such as cabinet side panels, bottom panels, and shelves to ensure the cabinet fits snugly against the wall. The seamless bonding with the ground necessitates the use of a cutting device. During the cutting operation, the reciprocating motor 18 is activated, and its output threaded rod 19 rotates. The rotation of the threaded rod 19 drives the sliding block 21 to move laterally along the through groove 20, thereby causing the cylinder 22, the cutting motor 24, and the cutting blade 25 to move laterally synchronously, achieving lateral cutting of the board surface by the cutting blade 25. Simultaneously, the cylinder 22 is activated, and its actuating end pushes the mounting bracket 23 to descend, causing the cutting blade 25 at the output end of the cutting motor 24 to contact the board. The cutting motor 24 rotates at high speed to drive the cutting blade 25 to cut. The lower blade groove 26 provides penetration space for the cutting blade 25, ensuring that the board is completely cut off.

[0030] After the cutting blade 25 has been used for a period of time, the handle 32 is turned to drive the screw 31 to rotate. The screw 31 is threaded with the outer side of the support frame 27. Through the threaded transmission, the sharpening stone 30 slides along the groove 28, so that the sharpening stone 30 and the cutting blade 25 come into contact. After the sharpening stone 30 and the cutting blade 25 come into contact, the cutting motor 24 drives the cutting blade 25 to rotate at a low speed to perform the sharpening operation. The rotational cooperation between the sharpening stone 30 and the cutting blade 25 removes the worn parts of the blade, restores the sharpness of the cutting blade 25, extends the service life of the tool, and ensures the cutting quality.

[0031] Working principle: According to the required cutting width of the board, the servo motor 8 is started, and its output shaft 10 starts to rotate. The gear 11 on the outside of the shaft 10 rotates accordingly. Since the gear 11 meshes with the rack 7, the rotation of the gear 11 is converted into the linear motion of the rack 7, which drives the slide plate 3 to slide in the slide groove 2. The positioning plate 4 on the top of the slide plate 3 moves synchronously with the slide plate 3. The operator can refer to the scale line 12 on the top side of the workbench 1 to intuitively determine the distance between the positioning plate 4 and the cutting blade 25. The servo motor 8 precisely controls the speed and number of rotations to achieve precise displacement of the positioning plate 4, meeting the cutting width requirements of different boards.

[0032] After the positioning plate 4 is adjusted, the plate is placed between the two fixed clamping plates 16, with one side of the plate in contact with one side of the positioning plate 4. The drive motor 13 rotates the bidirectional lead screw 14 at its output end. Since the threads at both ends of the bidirectional lead screw 14 turn in opposite directions, and the two fixed clamping plates 16 are engaged with the bidirectional lead screw 14 through screw holes, when the bidirectional lead screw 14 rotates, the two fixed clamping plates 16 will move towards or away from each other along the rectangular groove 15. Adjusting the distance between the fixed clamping plates 16 ensures that plates of different lengths are firmly clamped, preventing the plates from shifting during cutting and affecting cutting accuracy and safety.

[0033] When performing the cutting operation, the reciprocating motor 18 is started, and the threaded rod 19 at its output end rotates. The rotation of the threaded rod 19 drives the sliding block 21 to move laterally along the through groove 20, thereby causing the cylinder 22, the cutting motor 24 and the cutting blade 25 to move laterally synchronously, so that the cutting blade 25 can make a lateral cut on the surface of the board. At the same time, the cylinder 22 is started, and its working end pushes the mounting bracket 23 to descend, so that the cutting blade 25 at the output end of the cutting motor 24 contacts the board. The cutting motor 24 rotates at high speed to drive the cutting blade 25 to cut. The lower blade groove 26 provides the cutting blade 25 with penetration space to ensure that the board is completely cut off.

[0034] After the cutting blade 25 has been used for a period of time, the handle 32 is turned to drive the screw 31 to rotate. The screw 31 is threaded with the outer side of the support frame 27. Through the threaded transmission, the sharpening stone 30 slides along the groove 28, so that the sharpening stone 30 and the cutting blade 25 come into contact. After the sharpening stone 30 and the cutting blade 25 come into contact, the cutting motor 24 drives the cutting blade 25 to rotate at a low speed to perform the sharpening operation. The rotational cooperation between the sharpening stone 30 and the cutting blade 25 removes the worn parts of the blade, restores the sharpness of the cutting blade 25, extends the service life of the tool, and ensures the cutting quality.
