DETAILED DESCRIPTION

[0030] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0031] See also Figures 1 to 8 The present invention provides a technical solution: a filing device for furniture plate processing, comprising a bottom plate 2 fixedly mounted on the top of a workbench 1, a rear plate 3 integrally formed on the top of the bottom plate 2, a shaft seat 4 fixedly mounted on the top of the bottom plate 2, a rotatable rotating shaft 5 mounted on the outer wall of the shaft seat 4, a driving connecting rod 6 fixedly mounted on the outer wall of the rotating shaft 5, a handle 7 rotatably mounted on the outer wall of the driving connecting rod 6, a file 8 fixedly connected to one end of the handle 7 away from its rotating point, a fixed shaft 12 fixedly mounted on the outer wall of the rear plate 3, a tension spring 13 rotatably mounted on the outer wall of the fixed shaft 12, and the other end of the tension spring 13 is rotatably connected to the outer wall of the file 8 away from the handle 7;

[0032] It also includes a clamping portion capable of fixing the plate to be filed;

[0033] The utility model also comprises a fulcrum assembly, which comprises a fulcrum block 16 capable of reciprocating rotation. The fulcrum block 16 can intermittently come into contact with the file 8 and exert downward pressure on the top of the file 8 .

[0034] See also Figure 1 as well as Figure 2When the device is used, the plate to be filed is first fixed by the clamping part, and the rotating shaft 5 is driven to rotate by the external driving component, thereby driving the driving connecting rod 6 to rotate. Under the cooperation of the fixed shaft 12 and the tension spring 13, the handle 7 and the file 8 will swing back and forth. When the file 8 moves in the direction close to the plate (that is, when moving in the forward direction), the fulcrum block 16 in the fulcrum assembly is rotated to contact with the file 8, and downward pressure is applied to the file 8, so that the file 8 is against the part of the plate to be filed, so that the file 8 files the plate in the process of moving toward the plate to complete the forward filing process. When the file 8 is in the process of resetting after completing a forward filing, the fulcrum block 16 is rotated in the opposite direction through the fulcrum assembly, and under the action of the tension spring 13, the fulcrum block 16 is separated from the file 8, and then the file 8 is separated from the plate, preventing the plate from being filed when the file 8 is reset.

[0035] In summary, mechanized operation reduces the frequency of manual operation, reduces the risk of accidental injury to operators, improves work safety, and allows the file 8 to exert force only when moving closer to the plate and relax when moving away from the plate, so that during the filing process only the cutting edge of the file 8 is used to file the plate, thereby reducing the wear of the cutting edge of the file 8 and extending the service life of the file 8.

[0036] It is worth mentioning that, according to the quick return characteristics of the crank slider, the file 8 will accelerate when moving the plate forward, which can remove material more quickly, increase the processing speed, and thus improve the overall work efficiency. In addition, the accelerated movement can reduce the vibration of the file 8 during the filing process, improve the stability and control of the operation, and thus obtain higher processing accuracy.

[0037] Further, the fulcrum assembly includes a sliding plate 31 horizontally slidably mounted on the outer wall of the rear plate 3, a rack 32 is arranged on the top of the sliding plate 31, a mounting frame 14 is fixedly connected to the outer wall of the rear plate 3, a driven shaft 15 is rotatably mounted on the outer wall of the mounting frame 14, a fulcrum block 16 is fixedly mounted on the outer wall of the driven shaft 15, the driven shaft 15 passes through the outer wall of the mounting frame 14 and is fixedly mounted with a gear 18, and the rack 32 can mesh with the gear 18;

[0038] It also includes a driving assembly that enables the sliding plate 31 to slide back and forth in the horizontal direction.

[0039] As can be seen from the above, when the external driving assembly drives the rotating shaft 5 to rotate, it will drive the file 8 to move back and forth. With the cooperation of the fulcrum block 16, the file 8 will file the plate while moving in the forward direction. Figure 3 When the file 8 moves in the forward direction, the sliding plate 31 is driven by the driving assembly to move toward the direction close to the rotating shaft 5, and the driven shaft 15 is rotated (by Figure 3For example, at this time, the driven shaft 15 rotates counterclockwise), thereby driving the fulcrum block 16 to rotate, so that the fulcrum block 16 contacts the file 8 and exerts downward pressure thereon, so that the file 8 is closely fitted to the part to be filed of the plate, thereby achieving the purpose of filing the plate when the file 8 moves forward;

[0040] When the file 8 moves in the reverse direction to reset, the driving assembly causes the sliding plate 31 to move away from the rotating shaft 5. Similarly, the driven shaft 15 drives the fulcrum block 16 to rotate in the reverse direction (to Figure 3 For example, at this time, the driven shaft 15 and the fulcrum block 16 rotate clockwise), so that the fulcrum block 16 is separated from the top of the file 8, and the file 8 is separated from the plate under the action of the tension spring 13, completing the release process.

[0041] Therefore, under the action of the driving assembly, when the file 8 moves forward, the fulcrum block 16 applies pressure to the file 8, so that the file 8 contacts the plate to complete the filing process. When the file 8 moves in the opposite direction to reset, the fulcrum block 16 releases the pressure applied to the file 8, thereby separating the file 8 from the plate. In this reciprocating motion, only the cutting edge of the file 8 files the plate, preventing wear on the cutting edge when the file 8 is reset, and providing a certain degree of protection for the plate.

[0042] Furthermore, the driving assembly includes a sliding frame 21 fixedly connected to the end of the sliding plate 31 away from the rack 32, the rotating shaft 5 passes through the outer wall of the shaft seat 4 and is fixedly installed with a rotating disk 20, the outer wall of the rotating disk 20 is fixedly installed with a driving block 22, and the driving block 22 can slide in the sliding frame 21, and an arc groove with an arc-shaped design is provided in the sliding frame 21, and the arc groove coincides with part of the rotation trajectory of the driving block 22.

[0043] See also Figure 3When the rotating shaft 5 is driven to rotate by the external structure, the rotating disk 20 and the driving block 22 will be driven to rotate along the axis of the rotating shaft 5. During the rotation of the driving block 22, it will slide in the sliding frame 21. In the initial stage, the sliding frame 21 is located on the left side of the rotating shaft 5. When the driving block 22 rotates, it drives the sliding frame 21 to slide to the right, thereby driving the sliding plate 31 to slide to the right, and then the fulcrum block 16 rotates to contact with the file 8 and exert downward pressure on it; when the sliding frame 21 moves to the point where its inner wall coincides with the rotation trajectory of the driving block 22 After that, the driving block 22 stops moving, and the driving block 22 slides in the arc groove in the sliding frame 21. During this process, the fulcrum block 16 always applies pressure to the file 8, and the file 8 moves forward to file the plate; when the file 8 is about to move in the opposite direction to reset, the driving block 22 is just at the lower end of the arc groove in the sliding frame 21. When the driving block 22 continues to rotate clockwise, it will drive the sliding frame 21 to slide to the left, thereby driving the fulcrum block 16 to rotate clockwise and disengage from the file 8, so that the file 8 releases the pressure on the plate and completes the reset.

[0044] Therefore, through the cooperation between the driving block 22 and the sliding frame 21, when the file 8 moves in the forward direction, it will drive the sliding plate 31 to move in the direction close to the rotating shaft 5, so that the fulcrum block 16 rotates and contacts with the file 8, and then the file 8 applies pressure to the plate to complete the filing process; when the file 8 moves in the reverse direction to reset, the sliding plate 31 moves in the direction away from the rotating shaft 5, so that the fulcrum block 16 rotates and disengages from the file 8, and then the file 8 releases the pressure on the plate to complete the reset process, thereby reciprocating to achieve the purpose of filing the plate in the forward direction.

[0045] Furthermore, a ratchet 19 is fixedly mounted on the outer wall of the gear 18, a pawl 23 is installed on the top of the sliding plate 31, which is inclined and can only rotate in the direction of the sliding plate 31, a torsion spring is installed between the pawl 23 and the sliding plate 31, and the pawl 23 and the ratchet 19 can be in contact with each other.

[0046] As can be seen from the above, when the file 8 moves forward, downward pressure is applied to the plate to complete the filing. When the file 8 moves in the reverse direction, the pressure on the plate is released to complete the resetting process. However, in actual situations, the plate is not filed at the same fixed depth when the file 8 is used, but it is gradually moved slowly to a deeper level. Removing too much material at one time may cause cracks or other damages on the surface of the plate, affecting the quality of the final product. Therefore, this embodiment focuses on solving the problem that filing can only be performed at a fixed depth. The following is a specific method:

[0047] In summary, the reciprocating rotation of the fulcrum block 16 to apply or release pressure on the file 8 is achieved by the reciprocating movement of the rack 32. On this basis, the top of the sliding plate 31 is rotatably mounted with a ratchet 23, and the outer wall of the gear 18 is fixedly mounted with a ratchet 19. In the initial stage, the rotating shaft 5 rotates clockwise to drive the file 8 to file the plate in the forward direction, and will drive the sliding plate 31 to move in the direction close to the rotating shaft 5, see Figure 3 Before the rack 32 meshes with the gear 18, the pawl 23 will first contact with the ratchet 19, thereby driving the ratchet 19 and the gear 18 to rotate, and then each time before the rack 32 is about to drive the gear 18 to rotate, the gear 18 will rotate a certain angle in advance, that is, the fulcrum block 16 will be closer to the file 8 before rotating in the direction of the file 8 each time. In this way, when the rack 32 meshes with the gear 18 and causes the gear 18 to rotate, the fulcrum block 16 will rotate a larger angle relative to the last time, that is, each time the pressure on the file 8 will be greater than the last time (see Figure 7 as well as Figure 8 ),like Figure 6 At the positions shown in a, b and c, the file 8 files the plate more deeply each time, thereby ensuring that each layer of material is removed evenly, providing more consistent processing accuracy, especially for projects requiring deep processing, and reducing the wear of the file 8 and damage to the plate.

[0048] It is worth mentioning that a damper is installed inside the gear 18 to prevent the gear 18 from resetting when the ratchet 23 moves, and can effectively prevent the gear 18 from excessively rotating due to inertia when the sliding plate 31 drives the gear 18 to rotate.

[0049] Furthermore, a cleaning sleeve 24 is slidably mounted on the outer wall of the file 8, a plurality of brushes 29 are fixedly mounted on the inner wall of the cleaning sleeve 24, the driven shaft 15 passes through the outer wall of the fulcrum block 16 and is rotatably mounted with a mounting sleeve 26, a mounting tube 27 is fixedly mounted on the outer wall of the mounting sleeve 26, a telescopic rod 25 is slidably mounted on the inner wall of the mounting tube 27, one end of the telescopic rod 25 away from the mounting tube 27 is rotatably connected to the outer wall of the cleaning sleeve 24, and a spring 33 is connected between one end of the telescopic rod 25 in the mounting tube 27 and the inner wall of the mounting tube 27.

[0050] Static electricity is generated when the file 8 is filing the plate. The surfaces of the file 8 and the plate are charged. These charges attract the dust particles filed off and make them adhere to the surface of the file 8. The edges of the file 8 or the grooves between the teeth are prone to accumulate dust particles. These particles are mechanically locked in the grooves during the filing process. The dust blocks the edge of the file 8, reducing the effective cutting area of ​​the file 8, resulting in a decrease in cutting force, making the filing process more laborious and inefficient. Therefore, this embodiment focuses on solving the problem of dust adhering to the surface of the file 8 due to static electricity. The specific solution is as follows:

[0051] See also Figure 4 as well as Figure 6 In the process of reciprocating movement of the file 8, under the action of the telescopic rod 25, the cleaning sleeve 24 and the file 8 will slide relative to each other, so that the brush 29 cleans the surface of the file 8. Figure 4 Taking the shown state as an example, when the file 8 moves in the forward direction, the cleaning sleeve 24 will move toward the handle 7 under the action of the telescopic rod 25. When the file 8 moves in the reverse direction to reset, the cleaning sleeve 24 will move away from the handle 7 under the action of the spring 33, so that the brush 29 cleans the surface of the file 8, so that dust particles attached to its surface fall off, prevent clogging of the cutting edge of the file 8, maintain the sharpness of the file 8, and improve cutting efficiency. The surface of the file 8 after cleaning is cleaner, the interference of dust particles is reduced, a smoother processed surface can be obtained, and the processing quality is improved.

[0052] Furthermore, a sealed chamber is formed between the telescopic rod 25 and the inner wall of one end of the mounting tube 27 close to the cleaning sleeve 24, and an air inlet hole is opened in the mounting tube 27 in the sealed chamber, and an air outlet pipe 28 that can communicate with the cleaning sleeve 24 is fixedly connected to the inner wall of the mounting tube 27 in the sealed chamber, and a one-way valve is installed in the air outlet pipe 28 and the air inlet, and a pressure relief valve is installed at the air outlet position of the air outlet pipe 28.

[0053] See also Figure 4 When the file 8 moves back and forth, it will drive the telescopic rod 25 to slide back and forth on the inner wall of the mounting tube 27. When the telescopic rod 25 moves in the direction close to the mounting tube 27, the enclosed space formed by one end of the telescopic rod 25 in the mounting tube 27 and the inner wall of the mounting tube 27 will increase or decrease. When the enclosed space increases, air will be sucked in from the outside through the air inlet hole. When the enclosed space decreases, the air in the space will be transported to the inside of the cleaning sleeve 24 through the air outlet pipe 28, thereby completing the blowing of the inner wall of the cleaning sleeve 24, blowing away the dust particles cleaned by the brush 29, achieving further cleaning, and preventing dust particles from accumulating continuously between the brushes 29, so as to prevent subsequent cleaning processes.

[0054] It is worth noting that the air outlet pipe 28 is a hose to prevent the air outlet pipe 28 from being damaged during the movement of the cleaning sleeve 24 .

[0055] Furthermore, the outer walls on both sides of the file 8 are provided with sliding grooves 34 , and the inner walls at both ends of the cleaning sleeve 24 are fixedly mounted with first protrusions 30 , and the two first protrusions 30 can slide in the corresponding sliding grooves 34 .

[0056] See also Figure 4 as well as Figure 5Through the cooperation of the first protrusion 30 and the second protrusion 35, the cleaning sleeve 24 is slidably installed on the outer walls of both sides of the file 8, thereby limiting the position of the file 8 in the front-rear direction.

[0057] Furthermore, a second protrusion 35 is fixedly mounted on the inner wall of the slide groove 34 .

[0058] See also Figure 4 as well as Figure 5 When the file 8 swings in the opposite direction to reset, the cleaning sleeve 24 will be gradually pulled to move simultaneously with the file 8. When one end of the telescopic rod 25 contacts the inner wall of the mounting tube 27, a force in the opposite direction will be applied to the cleaning sleeve 24. Under the action of the second protrusion 35, this force will not initially cause the cleaning sleeve 24 to move in the direction close to the mounting tube 27, and the spring 33 will gradually lengthen. When the pulling force of the spring 33 on the telescopic rod 25 reaches a preset value, the first protrusion 30 will overcome the resistance to the second protrusion 35, thereby moving in the direction close to the mounting tube 27. At this time, due to the instantaneous release of the pulling force of the spring 33, the initial velocity of the cleaning sleeve 24 will be increased, so that the cleaning sleeve 24 has a faster speed when cleaning the surface of the file 8. The faster speed of the brush 29 can more quickly remove dust and debris on the surface of the file 8, ensuring that the file 8 is always kept clean and improving the cutting efficiency during the filing process.

[0059] Furthermore, the clamping part includes a mounting plate 9 fixedly mounted on the top of the base plate 2, and two clamping blocks 10 are slidably mounted on the top of the mounting plate 9. The outer walls of the two clamping blocks 10 are both penetrated by threaded grooves, and screws 11 are installed in the threaded grooves.

[0060] See also Figure 1 as well as Figure 2 When filing the plate, the plate to be filed is placed on the top of the mounting plate 9, and the plate is fixed by rotating the screw 11, thereby completing the subsequent filing process.

[0061] Furthermore, a convex groove 17 is installed on the top of the file 8, and the fulcrum block 16 can slide in the convex groove 17.

[0062] See also Figure 2 During the reciprocating movement of the file 8, the fulcrum block 16 will slide in the convex groove 17, thereby completing the front and rear limit of the file 8, making the file 8 more stable during the filing of the plate and preventing dislocation.
