Description

Technical Field

[0001] This utility model relates to the field of sheet metal processing technology, and in particular to a positioning fixture for automated cutting of furniture sheets. Background Technology

[0002] This clamp is used for the precise positioning and fixation of furniture panels on automated cutting equipment, ensuring cutting accuracy and improving production efficiency.

[0003] Patent CN220516067U discloses a positioning fixture for sheet metal processing and cutting, comprising a main body, a clamping mechanism on the main body, the clamping mechanism including a movable groove, and first fixing plates disposed on the left and right edges of the movable groove. A first motor is disposed on the side wall of one side of the first fixing plate, a first rotating shaft is disposed between the two sets of first fixing plates, two sets of support rings are sleeved on the side wall of the first rotating shaft, and several sets of toothed plates are disposed on the side wall of the support rings. Two sets of sliding grooves are disposed through the top of the main body, and cutting mechanisms are disposed on the left and right sides of the main body. The cutting mechanism includes... The system includes a support rod box, and a second motor is installed on the side wall of each of the two support rod boxes. A screw is installed inside the support rod box. When cutting the sheet metal, the sheet metal is first placed on the main body, and then clamped by a clamping mechanism. The sheet metal is then cut by a cutting mechanism. However, during the cutting process, since the sheet metal is fixed by the clamping mechanism, the cutting relies entirely on the screw driving the electric telescopic rod to move the cutting blade back and forth to cut the sheet metal. Therefore, the cutting length of the sheet metal is affected by the range of movement of the cutting blade. Furthermore, the sheet metal needs to be replaced by workers after cutting, which increases the workload of the workers.

[0004] Therefore, it is necessary to provide a new positioning fixture for automated cutting of furniture panels to solve the above-mentioned technical problems. Utility Model Content

[0022] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0023] Please refer to the following: Figure 1 — Figure 5 ,in, Figure 1 A schematic diagram of the overall structure of the positioning fixture for automated cutting of furniture panels provided by this utility model; Figure 2 A schematic diagram of the limiting component structure of the positioning fixture for automated cutting of furniture panels provided by this utility model; Figure 3 A schematic cross-sectional view of the limiting component of the positioning fixture for automated cutting of furniture panels provided by this utility model; Figure 4 A cross-sectional schematic diagram of the lifting assembly of the positioning fixture for automated cutting of furniture boards provided by this utility model; Figure 5 for Figure 3 A magnified view of point a shown below.

[0024] In practical implementation, a positioning fixture for automated cutting of furniture panels has the following structure: Figure 1 — Figure 5 As shown, it includes: a workbench 1, a storage bin 2 welded to the top of the workbench 1, a conveyor belt 3 rotatably connected to the bottom of the storage bin 2, and the conveyor belt 3 rotatably connected inside the workbench 1, a limiting component 4 for positioning the plate is engaged with the top of the workbench 1 by a clamping component 5, a cutting component 6 is provided at the top of the workbench 1, a lifting component 7 for driving the cutting component 6 to rise and fall is welded to the upper surface of the workbench 1, and multiple rotating rollers 8 are rotatably connected to the side of the workbench 1 away from the storage bin 2, and a driving component 9 for driving the rotating rollers 8 to rotate is inserted into the rotating rollers 8 adjacent to the cutting component 6;

[0025] The storage chamber 2 has an outlet on the side adjacent to the cutting component 6, with a height greater than the thickness of the plate and a width equal to the width of the plate. One end of the conveyor belt 3 is inserted into the center of the inner cavity of the storage chamber 2. The end of the plate away from the outlet abuts against the bottom wall of the inner cavity of the storage chamber 2. This is to prevent the plate above the lowest plate from tilting due to the supporting force of the lowest plate when the lowest plate is transported by the conveyor belt 3. At this time, one end of the plate above the lowest plate abuts against the side wall of the inner cavity of the storage chamber 2, and the other end of the plate above the lowest plate abuts against the bottom wall of the inner cavity of the storage chamber 2. This is to prevent wear on the conveyor belt 3. The limiting component 4 is located between the cutting component 6 and the conveyor belt 3.

[0026] It should be noted that when cutting furniture boards, multiple furniture boards to be cut are first stored in storage bin 2. Then, the conveyor belt 3 is started. The conveyor belt 3 drives the boards to move towards the cutting component 6 through friction. The limiting component 4 applies downward pressure to the boards to increase the pressure of the boards on the conveyor belt 3, thereby increasing the friction between the conveyor belt 3 and the boards and preventing the boards from moving freely when the cutting component 6 is cutting them. After the boards are cut, they are sent out by the action of the conveyor belt 3 and the rotating roller 8. At the same time, when the previous board has completely slid out of the storage bin 2, the next board will fall onto the conveyor belt 3, thus repeating the above steps. This achieves automated cutting of multiple boards, avoids the need for workers to change boards, and reduces the workload of workers.

[0027] It should be noted that when the conveyor belt 3 transports one end of the sheet to below the limiting component 4, the storage bin 2 can prevent the end of the sheet away from the limiting component 4 from tilting up. When the sheet is completely out of the storage bin 2, the end of the sheet away from the storage bin 2 is located just below the cutting component 6. Thus, the cutting component 6 can prevent the end of the sheet away from the limiting component 4 from tilting up, thereby ensuring the normal transport of the sheet by the conveyor belt 3.

[0028] The limiting component 4 includes a first mounting frame 41 and a second mounting frame 42. The first mounting frame 41 and the second mounting frame 42 are arranged opposite to each other on both sides of the worktable 1. Two oppositely arranged clamping components 5 are slidably connected inside the first mounting frame 41. A first fixing post 43 is welded to the top of the first mounting frame 41. A first threaded screw 44 is rotatably connected inside the first fixing post 43. A first drive motor 45 for driving the first threaded screw 44 to rotate is bolted to the top of the first fixing post 43. A second fixing post 46 is welded to the top of the second mounting frame 42. A first guide rod 47 is inserted inside the second fixing post 46. A connecting rod 48 is externally threaded to the first threaded screw 44. The other end of the connecting rod 48 is slidably connected to the outside of the first guide rod 47. A pressing roller 49 is rotatably connected to the outside of the connecting rod 48.

[0029] Mounting bracket 2 42 has a threaded connection to the side wall of the clamping bolt 410. By rotating the clamping bolt 410, the friction between the clamping bolt 410 and the side wall of the worktable 1 is increased, thereby limiting the position of mounting bracket 2 42.

[0030] It should be noted that the drive motor 45 drives the threaded screw 44 to rotate, and the threaded screw 44 drives the connecting rod 48 to rise and fall along the direction of the guide rod, thereby driving the pressing roller 49 to squeeze the plate, increasing the pressure applied by the pressing roller 49 to the plate, thereby increasing the supporting force applied by the conveyor belt 3 to the plate, and thus increasing the friction between the plate and the conveyor belt 3.

[0031] The clamping assembly 5 includes an elastic element 51, which is welded to the top wall of the inner cavity of the mounting frame 41. A sliding block 52 is welded to the end of the elastic element 51 away from the top wall of the inner cavity of the mounting frame 41. A plurality of serrations 53 are fixedly connected to the bottom end of the sliding block 52. A connecting plate 54 is rotatably connected to the side wall of the slider. The connecting plate 54 is rotatably connected to the side wall of the inner cavity of the mounting frame 41. An extension end 55 is rotatably connected to the end of the connecting plate 54 away from the slider. The extension end 55 penetrates the top wall of the mounting frame 41.

[0032] The upper and lower ends of the workbench 1 are provided with slide grooves 11, and multiple limiting teeth 12 that limit the saw teeth 53 are fixedly connected in the slide grooves 11.

[0033] It should be noted that under the elastic force of the elastic element 51, the sliding block 52 engages with the limiting tooth 12, thereby limiting the mounting bracket 41.

[0034] The lifting assembly 7 includes a guide post 1 71 and a guide post 2 72 that are respectively disposed on both sides of the top of the worktable 1. A threaded screw 2 73 is rotatably connected inside the guide post 1 71. A drive motor 2 74 that drives the threaded screw 2 73 is bolted to the top of the guide post 1 71. A guide rod 2 75 is welded inside the guide post 2 72. An electric slide rail 76 is inserted between the guide rod 2 75 and the threaded screw 2 73. A cutting assembly 6 is slidably connected to the bottom of the electric slide rail 76.

[0035] It should be noted that the distance between mounting bracket 41 and mounting bracket 42, and the distance between guide post 71 and guide post 72, are equal to the width of the plate. This is to prevent the plate from moving left and right when the cutting assembly 6 is cutting it. Since the plate has completely slid out of the storage bin 2 when the cutting assembly 6 is cutting it, the second plate will fall onto the conveyor belt 3. Even if the first plate moves backward when it is being cut, the first plate will come into contact with the second plate. At this time, the second plate will exert resistance on the first plate to prevent it from sliding backward, thus further preventing the first plate from moving during the cutting process.

[0036] It should be noted that the electric slide rail 76 converts the rotational motion of the motor into the linear motion of the slide table through a motor-driven transmission mechanism. Its core structure includes a guide rail, a slider, a transmission mechanism, a motor, and a control system. It achieves precise positioning and speed adjustment through closed-loop or open-loop control, thereby completing the preset linear displacement task and realizing automation.

[0037] The cutting assembly 6 includes a fixing block 61, which is slidably connected to the bottom end of the electric slide rail 76. An installation cavity is provided in the fixing block 61, and a cutting blade 62 is inserted in the installation cavity. A drive motor 63 for driving the cutting blade 62 to rotate is bolted to the side wall of the fixing block 61.

[0038] It should be noted that the cutting component 6 is positioned by sliding guide rail according to the shape and position of the material to be cut. After positioning is completed, the drive motor 63 is started, and the drive motor 63 drives the cutting blade 62 to rotate, thereby cutting the material.

[0039] The drive unit 9 includes a mounting shell 91, which is welded to the side wall of the workbench 1. A drive motor 92 is bolted inside the mounting shell 91. The output end of the drive motor 92 is welded to the rotating roller 8. The drive motor 92 drives the rotating roller 8 to move the cut plate.

[0040] The circuits and controls involved in this utility model are all existing technologies, and will not be described in detail here.

[0041] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the content of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
