Abstract
Description
Technical Field
[0001] This invention relates to the field of woodworking technology, and in particular to a grooving device for the frame of a wooden sofa. Background Technology
[0002] A wood grooving machine is a mechanical device specifically designed for grooving wood boards. It is widely used in woodworking, furniture manufacturing, and building decoration. In the production of wooden sofas, grooving machines are required for steps such as mortise and tenon joints in sofa frame construction, reinforcement structure installation of back and seat frames, and processing of decorative lines or functional grooves. For example, in the mortise and tenon splicing of solid wood frames, grooving machines can precisely create mortises to ensure structural stability. When using a grooving machine to create equidistant slots in a wooden board, adjusting the position of the board is usually better than adjusting the position of the drill bit. Existing grooving machines adopt a structural design with a fixed drill bit and a movable worktable, which eliminates the need to frequently adjust the height or angle of the drill bit. This reduces the complexity of operation and avoids mechanical adjustment steps such as loosening and tightening screws and calibrating angles. It can be achieved simply by loosening the clamps, moving the board, and re-fixing it. For mass production scenarios, adding a CNC system or a servo motor-driven worktable can enable automatic equidistant movement of the wooden board, further improving efficiency and accuracy. However, in actual use, since the equidistant continuous displacement direction of the wooden board remains unchanged, while the clamp needs to move back and forth multiple times to release and fix it, in order to avoid mutual interference in the processing, the movement of the wooden board and the clamp are mostly driven by two independent power sources. The two power sources operate completely independently and without coordinated control. It is easy for the wooden board to not be completely released from the fixation due to response delay or mechanical jamming after the clamp release command is issued. At this time, the moving system has already started, the clamp has not been fully released and the wooden board has started to move, resulting in wear on the surface of the wooden board. Summary of the Invention
[0003] The purpose of this invention is to address the problem that most wooden board movements and clamps are driven by two independent power sources. These two power sources operate completely independently without coordinated control, which can easily lead to situations where, after the clamp release command is issued, the wooden board is not completely released from the fixation due to response delay or mechanical jamming. At this time, the moving system has already started, the clamp is not fully released, and the wooden board begins to move, resulting in wear on the surface of the wooden board. Therefore, this invention proposes a grooving device for the frame of a wooden sofa.
[0004] To achieve the above objectives, the present invention employs the following technology: a frame grooving device for manufacturing wooden sofas. Includes a base, on which a grooving drill bit for grooving a wooden board and a movable seat for placing the wooden board are installed. The movable seat is provided with a positioning mechanism for fixing the position of the wooden board. The positioning mechanism includes a pressure plate that fits against the surface of the wooden board and a housing set on the movable seat. A guide is provided in the middle of the housing. The guide includes a fixed mounting shell and a rotating part that is rotatably set in the mounting shell. A wave-shaped guide groove is opened on the surface of the rotating part. The housing is also equipped with a vertically lifting platform. The lifting platform includes a guide shaft embedded in a guide groove and a pressure plate mounting part connected to the pressure plate. When the rotating part rotates, it guides the guide shaft through the guide groove, so that the guide shaft drives the pressure plate to reciprocate vertically through the pressure plate mounting part. The housing is provided with a drive mechanism for moving the wooden board. The drive mechanism includes a support plate for carrying the wooden board and rollers rotatably mounted on the support plate. The rollers are in contact with the wooden board and rotate synchronously with the rotating parts. When the roller rotates, it drives the wooden board to move. After moving a specified distance, the pressure plate descends to fix the wooden board and a groove is made by the grooving drill bit. After the grooving is completed, the pressure plate is raised while the roller continues to drive the wooden board to move.
[0005] A further description of the frame grooving device for producing wooden sofas according to the above-mentioned technology: The positioning mechanism also includes a meshing part located at the bottom of the housing. A screw slide is provided on the movable seat and meshes with the meshing part. By activating the screw slide, the screw slide drives the meshing part to move the wooden board horizontally along the length of the grooving drill bit, so that the wooden board contacts the grooving drill bit. After grooving is completed, the screw slide reverses to separate the wooden board from the grooving drill bit.
[0006] A further description of the frame grooving device for producing wooden sofas according to the above-mentioned technology: The housing is equipped with a slide rod, and a nested part is slidably embedded on the surface of the slide rod. The guide shaft and the pressure plate mounting part are both fixedly connected to the nested part. The guide shaft is slidably embedded in the groove opened in the inner wall of the meshing part through the slide member provided on one side.
[0007] A further description of the frame grooving device for producing wooden sofas according to the above-mentioned technology: A spring is wound around the surface of the slide bar, and the two ends of the spring are connected to the bottom of the nest and the inner wall of the housing, respectively.
[0008] A further description of the frame grooving device for producing wooden sofas according to the above-mentioned technology: The rotating component is driven to rotate by a rotating rod. The surface of the rotating rod is provided with a plurality of first limiting blocks, and the rotating component is provided with a first limiting groove that engages with the first limiting blocks.
[0009] A further description of the frame grooving device for producing wooden sofas according to the above-mentioned technology: The rotating component is guided by a pitch-changing mechanism to slide the first limiting groove on the first limiting block. The pitch-changing mechanism includes a threaded part on the surface of the rotating rod, and an internal threaded collar is engaged on the threaded part. An engagement groove is opened on the outer side of the internal threaded collar, and an engagement ring is provided on the rotating component that is rotatably engaged in the engagement groove. When the engagement groove rotates, it cooperates with the threaded part to drive the rotating component to rise and fall vertically along the length direction of the first limiting block, so as to change the distance between the pressure plate and the wooden board. The surface of the mounting housing has a straight hole for the guide shaft to pass through and move.
[0010] A further description of the frame grooving device for producing wooden sofas according to the above-mentioned technology: The drive mechanism also includes a fixed support part disposed on the housing, a bearing plate slidably embedded in the fixed support part, and a movable support part slidably embedded at the other end of the bearing plate; The movable support is provided with two rollers, which together with the rollers provided on the support plate form a triangular division.
[0011] A further description of the frame grooving device for producing wooden sofas according to the above-mentioned technology: The roller includes a mounting base set on a bearing plate and a movable support. A rotating shaft is rotatably mounted in the mounting base via a bearing. A wheel body is fitted on the surface of the rotating shaft. The rotating shaft is connected to a rotating rod via a transmission mechanism.
[0012] A further description of the frame grooving device for producing wooden sofas according to the above-mentioned technology: The transmission mechanism includes a drive wheel sleeved on a rotating rod for receiving power input, and a driven wheel sleeved on a rotating shaft for outputting power. The drive wheel and the driven wheel have the same module, but the drive wheel has more teeth than the driven wheel. A transmission belt is sleeved on the surface of the drive wheel and the driven wheel.
[0013] A further description of the frame grooving device for producing wooden sofas according to the above-mentioned technology: A rotatable turntable is provided through the middle of the movable seat, and a screw slide is fixedly mounted on the turntable. The movement of the movable seat and the rotation of the turntable are both driven by an adjustment mechanism. The adjustment mechanism includes a slide table mounted on a movable seat and a first servo motor mounted at the bottom of the movable seat. The base is provided with a slide rail and a rack that are slidably embedded in the slide table. The output end of the first servo motor is provided with a first gear that meshes with the rack. In addition, a second servo motor is provided at the bottom of the movable seat and a second gear is provided at the bottom of the turntable. A third gear that meshes with the second gear is provided on the output end of the second servo motor.
[0014] One of the above technical solutions has the following advantages or beneficial effects: 1. Through the positioning mechanism, drive mechanism and transmission mechanism, when the drive motor drives the rotating rod to rotate, the rotating rod drives the driven wheel to rotate through the driving wheel and the transmission belt, so that the driven wheel drives the rotating shaft to rotate under the restriction of the bearing. The rotating shaft drives the wooden board to move through the wheel body, thereby achieving the purpose of synchronizing the lifting and lowering of the pressure plate with the movement of the wooden board. When the roller rotates and drives the wooden board to move, the pressure plate begins to descend. After moving a certain distance, the pressure plate is fixed to the surface of the wooden board, and the drive motor stops. This improves the synchronization between the pressure plate and the roller, ensuring that the pressure plate is released and the wooden board moves at the same time, avoiding the situation where multiple power sources are not synchronized due to control signal delay or response speed differences. 2. Through the variable pitch mechanism, the internal threaded collar is rotated, causing it to rise and fall vertically along the length of the rotating rod under the constraint of the threaded part. The internal threaded collar drives the rotating part to move inside the mounting shell through the fitting groove and the fitting ring. At the same time, a straight hole is opened on the surface of the mounting shell for the guide shaft to pass through and move. As the rotating part descends, the guide shaft moves along the length of the straight hole under the drive of the guide groove. The guide shaft drives the pressure plate to move, thereby changing the distance between the pressure plate and the wooden board. Attached Figure Description

[0017] The following will describe in detail, with reference to the accompanying drawings of the embodiments of the present invention, a frame grooving device for producing wooden sofas according to the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of them. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.
[0018] To address the problem that most wooden board movement and clamping systems rely on two independent power sources, operating completely independently without coordinated control, which can lead to situations where, after the clamp release command is issued, the board is not fully released due to response delays or mechanical jamming, while the movement system has already started, causing the board to begin moving and resulting in surface wear, this invention proposes a frame grooving device for wooden sofa production. Figure 1 - Figure 15 As shown: Includes a base 11, on which a grooving drill bit 12 for grooving the wooden board and a movable seat 13 for placing the wooden board are mounted, such as Figure 15 As shown, a rotatable turntable 14 is provided through the middle of the movable seat 13, and a screw slide 15 is fixedly mounted on the turntable 14. The movement of the movable seat 13 and the rotation of the turntable 14 are both driven by the adjustment mechanism 60. The adjustment mechanism 60 includes a slide 62 mounted on the movable base 13 and a first servo motor 64 mounted at the bottom of the movable base 13. The base 11 is provided with a slide rail 61 and a rack 63 that are slidably embedded in the slide 62. The output end of the first servo motor 64 is provided with a first gear 65 that meshes with the rack 63. When it is necessary to adjust the position of the screw slide 15, the first servo motor 64 is started, causing the first servo motor 64 to drive the first gear 65 to rotate. The first gear 65, in conjunction with the rack 63, drives the slide 62 to slide under the restriction of the slide rail 61, thereby achieving the purpose of driving the screw slide 15 to move horizontally. The distance of horizontal movement is the length of the slot opening. The bottom of the operating room movable seat 13 is equipped with a second servo motor 67, and the bottom of the turntable 14 is equipped with a second gear 66. The output end of the second servo motor 67 is equipped with a third gear 68 that meshes with the second gear 66. By starting the second servo motor 67, the second servo motor 67 drives the second gear 66 to rotate through the third gear 68. The second gear 66 drives the turntable 14 to rotate under the restriction of the movable seat 13, thereby changing the angle between the screw slide 15 and the grooving drill bit 12, thus providing the function of opening irregular grooves on the wooden board.
[0019] A positioning mechanism 20 is engaged with the screw slide 15. The positioning mechanism 20 includes a pressure plate 29 that adheres to the surface of the wooden board and a meshing part 21 that meshes with the screw slide 15. By starting the screw slide 15, the screw slide 15 drives the meshing part 21 to move the wooden board horizontally along the length of the grooving drill bit 12. The moving distance is the grooving depth. The wooden board contacts the grooving drill bit 12. The moving distance of the wooden board is the grooving depth. At this time, by starting the first servo motor 64, the screw slide 15 moves the wooden board horizontally to perform grooving. After grooving is completed, the screw slide 15 reverses to separate the wooden board from the grooving drill bit 12. To secure the wooden board to the screw slide 15, such as Figure 2 As shown, a housing 22 is provided on the meshing part 21, and a guide 25 is provided in the middle of the housing 22, such as... Figure 3 As shown, the guide member 25 includes a fixedly mounted mounting shell 251 and a rotating member 253 rotatably mounted inside the mounting shell 251. The rotating member 253 has a wave-shaped guide groove 254 on its surface. like Figure 7 As shown, the housing 22 also includes a vertically adjustable lifting platform 27. The lifting platform 27 includes a guide shaft 272 embedded in the guide groove 254 and a pressure plate mounting part 273 connected to the pressure plate 29. Figure 2 As shown, a drive motor 23 with its output end connected to the rotating rod 24 is provided at the top of the meshing part 21, such as... Figure 3 and Figure 4 As shown, by starting the drive motor 23, the drive motor 23 drives the rotating rod 24 to rotate. The rotating rod 24 drives the rotating part 253 to rotate under the restriction of the mounting shell 251. When the rotating part 253 rotates, it guides the guide shaft 272 through the guide groove 254, so that the guide shaft 272 drives the pressure plate 29 to reciprocate vertically through the pressure plate mounting part 273. To ensure that the pressure plate 29 does not shift during the lifting and lowering process, such as Figure 2 - Figure 5 , Figure 7 As shown, a slide rod 26 is provided inside the housing 22, and the lifting platform 27 also includes a nesting member 271 that is slidably embedded in the surface of the slide rod 26. The guide shaft 272 and the pressure plate mounting part 273 are both fixedly connected to the nesting member 271. The guide shaft 272 is slidably embedded in the slide groove 28 opened in the inner wall of the meshing part 21 through a slide member 274 provided on one side, so as to limit the movement direction of the pressure plate mounting part 273 and avoid angular deviation during the lifting process. Furthermore, such as Figure 7 As shown, a spring 261 is wound around the surface of the slide bar 26. The two ends of the spring 261 are connected to the bottom of the nested part 271 and the inner wall of the housing 22, respectively. When the pressure plate 29 lowers to fix the wooden board, the spring 261 is squeezed by the nested part 271, causing the spring 261 to undergo elastic deformation. When the pressure plate 29 is released from fixing, the spring 261 provides thrust through elastic deformation recovery, so that the nested part 271 quickly returns to the initial position, thereby reducing the reset time and compensating for the error caused by response delay or mechanical jamming.
[0020] In order to drive the wooden board to move multiple equidistant distances while simultaneously fixing and releasing the pressure plate 29, such as Figure 13 - Figure 14 As shown, the housing 22 is provided with a drive mechanism 40 for moving the wooden board. The drive mechanism 40 includes a support plate 42 for carrying the wooden board and a roller 45 rotatably mounted on the support plate 42. The roller 45 is in contact with the wooden board and rotates synchronously with the rotating component 253. The drive mechanism 40 also includes a fixed support part 41 disposed on the housing 22. The bearing plate 42 is slidably embedded in the fixed support part 41. The other end of the bearing plate 42 is slidably embedded in the movable support part 43. The movable support part 43 is provided with two rollers 45, which form a triangular division with the rollers 45 disposed on the bearing plate 42. When fixing the wooden board, the bearing plate 42 and the movable support part 43 are pulled and unfolded so that the wooden board can be placed on the bearing plate 42. Then the movable support part 43 is pushed so that the movable support part 43 pushes the bearing plate 42 to move and retract towards the fixed support part 41. At the same time, the three rollers 45 are respectively attached to the two sides of the wooden board. After the bearing plate 42 and the movable support part 43 are fixed in position with fastening bolts, the installation of the wooden board is completed. To prevent the support plate 42 and the movable support 43 from completely detaching from the fixed support 41, such as Figure 13 As shown, both the fixed support part 41 and the movable support part 43 are provided with guide rails 44 that are slidably embedded in the bottom of the support plate 42 to limit the sliding distance between the support plate 42 and the movable support part 43. like Figure 14 As shown, the roller 45 includes a mounting base 451 disposed on the support plate 42 and the movable support part 43. A rotating shaft 453 is rotatably disposed in the mounting base 451 via a bearing 452. A wheel body 454 is sleeved on the surface of the rotating shaft 453. The rotating shaft 453 is connected to the rotating rod 24 via a transmission mechanism 50. The transmission mechanism 50 includes a driving wheel 51 sleeved on the rotating rod 24 for receiving power input, and a driven wheel 52 sleeved on the rotating shaft 453 for outputting power. The driving wheel 51 and the driven wheel 52 have the same module, but the driving wheel 51 has more teeth than the driven wheel 52. Therefore, a transmission belt 53 is fitted on the surface of the driving wheel 51 and the driven wheel 52. It should be noted that the rotating rod 24 can drive the pressure plate 29 to complete the lifting and lowering action by rotating half a turn. Therefore, by setting the driving wheel 51 and the driven wheel 52 with a large difference in the number of teeth, the speed can be increased by multiple times, so that the driven wheel 52 can drive the wheel body 454 to rotate more times, which meets the movement requirements of the wooden board. At the same time, by replacing the driven wheel 52 with different numbers of teeth and the transmission belt 53 that are adapted to it, the number of rotations of the wheel body 454 can also be adjusted to change the movement distance of the wooden board. When the drive motor 23 drives the rotating rod 24 to rotate, the rotating rod 24 drives the driven wheel 52 to rotate through the driving wheel 51 and the transmission belt 53, so that the driven wheel 52 drives the rotating shaft 453 to rotate under the restriction of the bearing 452. The rotating shaft 453 drives the wooden board to move through the wheel body 454, thereby achieving the purpose of synchronizing the lifting and lowering of the pressure plate 29 with the movement of the wooden board. When the roller 45 rotates and drives the wooden board to move, the pressure plate 29 begins to descend. After moving a certain distance, the pressure plate 29 is fixed to the surface of the wooden board. The drive motor 23 stops. At this time, the screw slide 15 is started, so that the screw slide 15 drives the wooden board to move towards the grooving drill bit 12. The wooden board contacts the grooving drill bit 12 and begins to grooving. Then the first servo motor 64 is started, so that the screw slide 15 drives the wooden board to move horizontally back and forth along the length direction of the slide rail 61 to complete the grooving. After the grooving is completed, the first servo motor 64 and the screw slide 15 sequentially drive the wooden board to separate from the grooving drill bit 12. At this point, the drive motor 23 is restarted, causing the drive motor 23 to lift the pressure plate 29 while continuing to move the wooden board through the roller 45. After moving a certain distance, the above grooving operation is repeated, thereby improving the synchronization between the pressure plate 29 and the roller 45, ensuring that the pressure plate 29 is released and the wooden board moves at the same time, avoiding the situation where multiple power sources are not synchronized due to control signal delays or differences in response speed.
[0021] like Figure 10 - Figure 12 As shown, in order to adjust the distance between the pressure plate 29 and the wooden board so that it can adapt to wooden boards of different thicknesses, the rotating part 253 guides the first limiting groove 255 to slide on the first limiting block 241 through the pitch changing mechanism 30. The pitch changing mechanism 30 includes a threaded part 31 provided on the surface of the rotating rod 24, and an internal threaded collar 32 is engaged on the threaded part 31. An engagement groove 33 is provided on the outer side of the internal threaded collar 32, and an engagement ring 34 is provided on the rotating part 253 that is rotatably embedded in the engagement groove 33. By rotating the internal threaded collar 32, the internal threaded collar 32 is vertically raised and lowered along the length of the rotating rod 24 under the restriction of the threaded part 31. The internal threaded collar 32 drives the rotating part 253 to move inside the mounting shell 251 through the fitting groove 33 and the fitting ring 34. At the same time, the surface of the mounting shell 251 is provided with a straight hole 252 for the guide shaft 272 to pass through and move. As the rotating part 253 descends, the guide shaft 272 moves along the length of the straight hole 252 under the drive of the guide groove 254. The guide shaft 272 drives the pressure plate 29 to move, thereby changing the distance between the pressure plate 29 and the wooden board. It is important to note that, such as Figure 12As shown, the surface of the rotating rod 24 is provided with a plurality of first limiting blocks 241, and the rotating part 253 is provided with a first limiting groove 255 that engages with the first limiting blocks 241. When the internal threaded collar 32 rotates and drives the rotating part 253 to move, the rotating part 253 drives the first limiting groove 255 to slide under the cooperation of the first limiting blocks 241. At this time, the rotating part 253 does not rotate. When the rotating rod 24 rotates, the rotating rod 24 drives the rotating component 253 to rotate through the first limiting block 241 and the first limiting groove 255. The rotating component 253 drives the fitting ring 34 to rotate under the restriction of the fitting groove 33.
[0022] To facilitate the rotation of the internal threaded collar 32 by the operator, a lever part 35 is provided on the internal threaded collar 32, which penetrates the top of the housing 22 and has the same diameter as the rotating part 253. A through hole with the same outer diameter as the rotating rod 24 is opened in the middle of the lever part 35, and several grooves are opened on the lever part 35. The operator can adjust the position of the rotating part 253 by rotating the fitting groove 33.
[0023] Working principle: By pulling the support plate 42 and the movable support 43, they can slide and unfold on the fixed support 41, leaving enough space for the wooden board to be placed. Place the wooden board to be grooved smoothly on the support plate 42, ensuring that the wooden board is placed in the right position and the surface is flat; Push the movable support part 43 so that it pushes the bearing plate 42 to move and retract toward the fixed support part 41, while the three rollers 45 respectively attach to the two sides of the wooden board; Secure the bearing plate 42 and the movable support 43 with fastening bolts to ensure that the wooden board is installed firmly and will not move during the grooving process; By rotating the actuating part 35, the internal threaded collar 32 is driven to rotate on the threaded part 31, so that the internal threaded collar 32 rises and falls vertically along the length of the rotating rod 24. The internal threaded collar 32 drives the rotating part 253 to move inside the mounting shell 251 through the fitting groove 33 and the fitting ring 34. At this time, the first limiting groove 255 of the rotating part 253 slides on the first limiting block 241, and the rotating part 253 does not rotate. As the rotating part 253 moves, the guide shaft 272 moves along the length of the straight hole 252 under the drive of the guide groove 254. The guide shaft 272 drives the pressure plate 29 to move through the pressure plate mounting part 273 until the distance between the pressure plate 29 and the surface of the wooden board is appropriate, so as to adapt to wooden boards of different thicknesses. Start the drive motor 23 to drive the rotating rod 24 to rotate. The rotating rod 24 drives the driven wheel 52 to rotate through the drive wheel 51 and the transmission belt 53. The driven wheel 52 drives the rotating shaft 453 to rotate under the restriction of the bearing 452. The rotating shaft 453 drives the wooden board to move through the wheel body 454. While the roller 45 rotates and drives the wooden board to move, the rotating rod 24 drives the rotating part 253 to rotate through the first limiting block 241 and the first limiting groove 255. When the rotating part 253 rotates, it guides the guide shaft 272 through the guide groove 254. The guide shaft 272 drives the pressure plate 29 to descend vertically through the pressure plate mounting part 273. At the same time, the guide shaft 272 slides in the slide groove 28 through the sliding part 274, which restricts the movement direction of the pressure plate mounting part 273 and avoids angular deviation during the lifting process. Start the screw slide 15, so that the screw slide 15 drives the wooden board to move horizontally back and forth along the length of the slide rail 61, and the grooving drill bit 12 performs grooving operation on the wooden board.
