Description

Technical Field

[0001] This application relates to the technical field of decoration equipment, and in particular to a wood cutting device suitable for diverse cutting needs. Background Technology

[0002] In home decoration, carpenters are usually needed to customize furniture such as cabinets and door and window frames. However, when faced with special construction requirements such as modifying the internal partitions of cabinets where the work space is small, or the design of curved door and window frames, it is difficult for carpenters to complete the corresponding wood cutting work using only a wood saw. This requires a lot of time and effort and results in high labor costs. Summary of the Invention

[0003] To meet the diverse cutting needs encountered by woodworkers during their work, this application provides a wood cutting device suitable for diverse cutting needs.

[0004] This application provides a wood cutting device suitable for diverse cutting needs, which adopts the following technical solution:

[0005] A wood cutting device suitable for diverse cutting needs includes a fixed frame, a first movable block slidably mounted on the fixed frame, a second movable block slidably mounted on the first movable block, the movement direction of the second movable block being perpendicular to the movement direction of the first movable block, two rotating wheels rotatably mounted on the second movable block, each of the outer walls of the two rotating wheels having serrations, two rotating motors mounted on the second movable block, the two rotating motors being respectively connected to the two rotating wheels, a first driving mechanism mounted on the fixed frame for driving the first movable block to move, and a second driving mechanism mounted on the first movable block for driving the second movable block to move.

[0006] By adopting the above technical solution, when facing a relatively narrow workspace, the second drive mechanism is activated to move the second moving block. The movement of the second moving block causes two rotating wheels to extend into the workspace. Then, the rotating motor is activated to drive the rotating wheels to rotate. At the same time, the first drive mechanism is activated to move the first moving block. The movement of the first moving block causes the rotating wheels to cut the wood, thus completing the work of cutting wood in relatively narrow spaces such as cabinets. When the wood has a need for cutting in an arc shape, the first drive mechanism and the second drive mechanism simultaneously drive the first moving block and the second moving block to drive the rotating wheels to cut the arc surface. This is convenient and quick, and improves the woodworker's adaptability to different wood cutting needs.

[0007] Optionally, the first drive mechanism includes:

[0008] The first driving block is slidably mounted on the fixed frame. The moving direction of the first driving block is perpendicular to the moving direction of the first moving block. An inclined guide surface is provided on the side wall of the first driving block.

[0009] A first drive spring is mounted on a fixed frame and connected to a first movable block. The first movable block abuts against a guide surface on the first drive block under the action of the first drive spring.

[0010] The first drive screw is rotatably mounted on the fixed frame and threadedly connected to the first drive block;

[0011] The first drive motor is mounted on a fixed frame and its output shaft is connected to the first drive screw.

[0012] By adopting the above technical solution, the first drive motor starts and drives the first drive screw to rotate, the rotation of the first drive screw drives the first drive block to move, and the movement of the first drive block drives the first moving block to move along the guide surface, thereby realizing the movement of the position of the first moving block by controlling the first drive motor.

[0013] Optionally, a mounting block is slidably mounted on the fixed frame. The mounting block is threadedly connected to the first drive screw. The first drive block is rotatably mounted on the mounting block. The inclination angles of the guide surfaces of the first drive block near and away from the first moving block are different. The inclination angle of the guide surfaces changes from large to small from the end of the first drive block near the first moving block to the end away from the first moving block. A rotating assembly is provided on the fixed frame to control the rotation angle of the first drive block.

[0014] By adopting the above technical solution, the tilt angles of the guide surfaces at both ends of the first driving block are set to different sizes. By rotating the first driving block with the rotating component, the tilt angle of the guide surface in contact between the first driving block and the first moving block can be adjusted and replaced, thereby adjusting the movement range of the first moving block and improving the movement accuracy of the first moving block.

[0015] Optionally, the rotating assembly includes:

[0016] A rotating shaft is rotatably mounted on a mounting block and connected to a first drive block;

[0017] A rotating gear, which is mounted on a rotating shaft;

[0018] A limiting plate is slidably disposed on the mounting block along the direction of the rotating gear toward or away from the rotating gear;

[0019] A limiting spring is provided on the mounting block and connected to a limiting plate. The limiting plate engages with the teeth on the rotating gear under the action of the limiting spring.

[0020] By adopting the above technical solution, when it is necessary to adjust the tilt angle of the guide surface in contact between the first driving block and the first moving block, the moving limiting plate compresses the limiting spring and moves, causing the limiting plate to disengage from the rotating gear, so that the rotating gear can be rotated. The rotation of the rotating gear drives the rotating shaft to rotate, and the rotation of the rotating shaft drives the first driving block to rotate until the first driving block rotates to the target position. Then the limiting plate is released, and under the action of the limiting spring, the limiting plate engages with the meshing teeth on the rotating gear to fix the position of the rotating gear, thereby completing the rotation and fixing of the position of the first driving block.

[0021] Optionally, a sliding groove is provided on the side wall of the first moving block away from the first driving block, and a slider is slidably mounted on the first moving block. The slider is partially located inside the sliding groove and partially extends out of the sliding groove. The first driving spring is connected to the end of the slider that extends out of the sliding groove. A second driving screw is rotatably mounted on the first moving block. The second driving screw is threadedly connected to the slider. The second moving block is slidably mounted on the slider through a second driving mechanism.

[0022] By adopting the above technical solution, a slider is slidably installed on the first moving block through a sliding groove. The position of the slider extending out of the first moving block can be adjusted by rotating the second drive screw. Thus, the position of the second moving block can be coarsely adjusted by using the second drive screw first, and then the position of the second moving block can be finely adjusted by moving the first drive block, thereby improving the accuracy of adjusting the position of the second moving block.

[0023] Optionally, the second drive mechanism includes:

[0024] The second drive cylinder is mounted on the slider, and the second moving block is mounted on the piston rod of the second drive cylinder.

[0025] The second drive rod is slidably mounted on the second moving block, and both the rotating wheel and the rotating motor are mounted on the second drive rod.

[0026] The second drive screw is threaded onto the second drive block and abuts against the second drive rod.

[0027] By adopting the above technical solution, the second drive screw is turned to disengage from the second drive rod. The second drive rod is then moved to drive the rotary wheel to the initial cutting position of the wood. Then, the second drive screw is turned to press against the second drive rod to fix the relative position of the second drive rod and the second drive block. After the position of the second drive rod is fixed, the second drive cylinder can be activated to drive the second moving block to move. The movement of the second moving block drives the rotary wheel to move and cut the wood, thus completing the moving and cutting work of the rotary wheel.

[0028] Optionally, a turntable is provided on the piston rod of the second drive cylinder, the second moving block is rotatably mounted on the turntable, a second drive motor is provided on the turntable, and the output shaft of the second drive motor is connected to the second moving block.

[0029] By adopting the above technical solution, a turntable is installed on the piston rod of the second drive cylinder, and the second moving block is rotatably connected to the turntable. When the second drive motor is started, it can drive the second moving block to rotate. The rotation of the second moving block drives the two rotating blocks to rotate. Thus, by controlling the second drive motor, the cutting angle of the rotary wheel can be adjusted, expanding the applicability of the rotary wheel to different cutting methods.

[0030] Optionally, the fixing frame is provided with a fixing mechanism, which is used to fix the position of the fixing frame. The fixing mechanism includes:

[0031] The fixed support legs are provided in multiple ways, and all of the multiple fixed support legs are rotatably mounted on the fixed frame;

[0032] A fixed suction cup is mounted on a fixed support leg.

[0033] A fixing bolt is provided on a fixing bracket located at the rotation point of the fixing leg, and the fixing bolt is threaded into the threaded hole with its head pressed against the fixing leg.

[0034] By adopting the above technical solution, the fixing bolts are loosened to detach from the fixing feet. Several fixing feet are rotated according to the work scenario so that the suction cups on the fixing feet can be attached to objects or surfaces in the work environment that can be fixed. Then, the fixing bolts are tightened to press against the fixing feet to fix them. This completes the fixed installation of the fixing frame in different work environments, and it has strong environmental adaptability.

[0035] Optionally, an adjustment disc is rotatably mounted on the fixed frame, the fixed support foot is set on the adjustment disc, an adjustment motor is set on the fixed frame, and the output shaft of the adjustment motor is connected to the adjustment disc.

[0036] By adopting the above technical solution, the adjustment plate is rotated and installed on the fixed frame, and the fixed feet are all installed on the adjustment plate. The position of the fixed feet can be adjusted by rotating the adjustment plate with the adjustment motor, thereby expanding the range of adaptability of the fixed feet to different usage scenarios.

[0037] Optionally, an infrared emitter is provided on the second drive rod, which emits infrared rays to the cutting position of the rotating wheel.

[0038] By adopting the above technical solution, an infrared transmitter is installed on the second drive rod, which emits infrared rays to the cutting position of the rotating wheel. This allows the operator to more intuitively grasp the cutting position in advance, thereby facilitating the operator to improve the cutting accuracy by adjusting the position of the rotating wheel.

[0039] In summary, this application includes at least one of the following beneficial technical effects:

[0040] 1. The second drive mechanism is activated to move the second moving block. The movement of the second moving block causes two rotating wheels to extend into the workspace. Then, the motor is activated to rotate the rotating wheels. At the same time, the first drive mechanism is activated to move the first moving block. The movement of the first moving block causes the rotating wheels to cut the wood, thus completing the work of cutting wood in relatively small spaces such as cabinets.

[0041] 2. By simultaneously driving the first and second moving blocks through the first and second driving mechanisms, the rotary wheel can be driven to perform arc-shaped surface cutting, which is convenient and quick, and improves the woodworker's adaptability to different wood cutting needs;

[0042] 3. By installing an infrared transmitter on the second drive rod, infrared rays are emitted to the cutting position of the rotating wheel, allowing the operator to more intuitively grasp the cutting position in advance, thus facilitating the operator to improve the cutting accuracy by adjusting the position of the rotating wheel.

[0050] Reference Figure 1 and Figure 2 The fixing mechanism 2 includes fixing feet 21, fixing suction cups 22, and fixing bolts 23. Multiple fixing feet 21 are provided, all rotatably mounted on the side wall of the adjusting plate 11 and evenly distributed along the side wall. The fixing suction cups 22 are fixedly mounted on the end of the fixing feet 21 away from the adjusting plate 11. Threaded holes are provided on the side wall of the adjusting plate 11 at the rotatable portion of the fixing feet 21. The fixing bolts 23 are threaded into the threaded holes, with their heads pressed against the fixing feet 21.

[0051] Reference Figure 1 and Figure 2 Tighten the fixing bolt 23 to disengage from the fixing leg 21. Rotate several fixing legs 21 according to the work scene so that the suction cups on the fixing legs 21 can be attached to objects or surfaces that can be fixed in the work environment. Then tighten the fixing bolt 23 to press against the fixing leg 21 to fix the fixing leg 21. This completes the fixed installation of the fixing frame 1 in different work environments, with strong environmental adaptability.

[0052] Reference Figure 1 and Figure 2 A first drive mechanism 3 is provided on the fixed frame 1, and a first moving block 13 is slidably mounted on the fixed frame 1 via the first drive mechanism 3. The first drive mechanism 3 includes a first drive block 31, a first drive screw 32, and a first drive motor 33. A mounting block 34 is slidably mounted on the fixed frame 1 along a direction perpendicular to the sliding direction of the first moving block 13, and the first drive block 31 is rotatably mounted on the mounting block 34. An inclined guide surface 35 is provided on the side wall of the first drive block 31. The first drive screw 32 is rotatably mounted on the fixed frame 1 and threadedly connected to the mounting block 34. The first drive motor 33 is fixedly mounted on the fixed frame 1, and its output shaft is fixedly connected to the first drive screw 32.

[0053] Reference Figure 1 and Figure 2 The end of the first moving block 13 near the first driving block 31 abuts against the guide surface 35 on the side wall of the first driving block 31. The inclination angles of the guide surfaces 35 at the two ends of the first driving block 31 near and away from the first moving block 13 are different, and the inclination angle of the guide surfaces 35 changes from large to small from the end of the first driving block 31 near the first moving block 13 to the end away from the first moving block 13. A rotating assembly 4 is provided on the fixed frame 1, which is used to control the rotation angle of the first driving block 31.

[0054] Reference Figure 1 and Figure 3 The rotating assembly 4 includes a rotating shaft, a rotating gear 42, a limiting plate 43, and a limiting spring 44. The rotating shaft is fixedly mounted on the first drive block 31. The rotating gear 42 is fixedly mounted on the rotating shaft. The limiting plate 43 is slidably mounted on the fixed frame 1 along the radial direction of the rotating gear 42. One end of the limiting spring 44 is fixedly mounted on the fixed frame 1, and the other end of the limiting spring 44 is connected to the limiting plate 43. Under the action of the limiting spring 44, the limiting plate 43 engages with the teeth on the rotating gear 42.

[0055] Reference Figure 2 and Figure 3 The first drive motor 33 starts and drives the first drive screw 32 to rotate. The rotation of the first drive screw 32 drives the mounting block 34 to move. The movement of the mounting block 34 drives the first drive block 31 to move. The movement of the first drive block 31 drives the first moving block 13 to move along the guide surface 35. Thus, the movement of the position of the first moving block 13 is achieved by controlling the first drive motor 33.

[0056] Reference Figure 2 and Figure 3When it is necessary to adjust the tilt angle of the guide surface 35 that contacts the first driving block 31 and the first moving block 13, the moving limiting plate 43 compresses the limiting spring 44 to move, so that the limiting plate 43 disengages from the rotating gear 42, and the rotating gear 42 can be rotated. The rotation of the rotating gear 42 drives the rotating shaft to rotate, and the rotation of the rotating shaft drives the first driving block 31 to rotate until the first driving block 31 rotates to the target position. Then the limiting plate 43 is released. Under the action of the limiting spring 44, the limiting plate 43 engages with the meshing teeth on the rotating gear 42 to fix the position of the rotating gear 42, thereby completing the rotation and fixing of the position of the first driving block 31.

[0057] Reference Figure 1 and Figure 2 A sliding groove is formed on the side wall of the first movable block 13 away from the first driving block 31. A slider 15 is slidably mounted on the first movable block 13, with part of the slider 15 located inside the sliding groove and part extending outside the sliding groove. A second driving screw 16 is rotatably mounted on the first movable block 13. The second driving screw 16 is threadedly connected to the slider 15. A second driving mechanism 5 is provided on the slider 15, and a second movable block 51 is slidably mounted on the slider 15 in a direction perpendicular to the sliding direction of the slider 15 via the second driving mechanism 5.

[0058] Reference Figure 1 and Figure 2 The slider 15 is slidably mounted on the first moving block 13 via a sliding groove. The position of the slider 15 extending out of the first moving block 13 can be adjusted by rotating the second drive screw 16. Thus, the position of the second moving block 51 can be coarsely adjusted by using the second drive screw 16, and then the position of the second moving block 51 can be finely adjusted by moving the first drive block 31, thereby improving the accuracy of adjusting the position of the second moving block 51.

[0059] Reference Figure 1 and Figure 2 The second drive mechanism 5 includes a second drive cylinder 52, a second drive rod 53, and a second drive screw 54. The second drive cylinder 52 is fixedly mounted on the surface of the slider 15. A turntable 55 is fixedly mounted on the piston rod of the second drive cylinder 52. A second moving block 51 is rotatably mounted on the side wall of the turntable 55 away from the second drive cylinder 52. A second drive motor 56 is fixedly mounted on the turntable 55, and the output shaft of the second drive motor 56 is connected to the second moving block 51. The second drive rod 53 is slidably mounted on the second moving block 51, and the second drive screw 54 is threadedly connected to the second moving block 51 and abuts against the outer side wall of the second drive rod 53.

A rotating motor 58 is fixedly mounted on the end of the second drive rod 53, and the output shaft of the rotating motor 58 is connected to the rotating wheel 57. The outer wall of the rotating wheel 57 has serrations. An infrared emitter 59 is mounted on the side wall of the second drive rod 53, and the infrared emitter 59 emits infrared rays to the cutting position of the rotating wheel 57.

[0061] Reference Figure 3 When faced with a relatively confined workspace, the second drive cylinder 52 is activated, driving the second drive rod 53 to move. The movement of the second drive rod 53 causes the two rotating wheels 57 to extend into the workspace. Then, the rotating motor 58 is activated, driving the rotating wheels 57 to rotate. At the same time, the first drive motor 33 is activated, driving the first moving block 13 to move. The movement of the first moving block 13 causes the rotating wheels 57 to cut the wood, thus completing the work of cutting wood in a relatively confined space such as a cabinet.

[0062] Reference Figure 2 When there is a need to cut wood in an arc shape, the first drive motor 33 and the second drive cylinder 52 work simultaneously to drive the first moving block 13 and the second drive rod 53 to move simultaneously, which can drive the rotating wheel 57 to perform arc-shaped cutting work. This is convenient and quick, and improves the woodworker's ability to adapt to different wood cutting needs.

[0063] The working principle of this application embodiment is as follows:

[0064] When faced with a relatively confined workspace, the second drive cylinder 52 is activated, driving the second drive rod 53 to move. The movement of the second drive rod 53 causes the two rotating wheels 57 to extend into the workspace. Then, the rotating motor 58 is activated, driving the rotating wheels 57 to rotate. At the same time, the first drive motor 33 is activated, driving the first moving block 13 to move. The movement of the first moving block 13 causes the rotating wheels 57 to cut the wood, thus completing the work of cutting wood in relatively confined spaces such as cabinets. When the wood needs to be cut in an arc shape, the first drive motor 33 and the second drive cylinder 52 work simultaneously, driving the first moving block 13 and the second drive rod 53 to move simultaneously, which can drive the rotating wheels 57 to perform arc-shaped cutting work, which is convenient and quick, and improves the woodworker's adaptability to different wood cutting needs.

[0065] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application.
