Description

Technical Field

[0001] This invention relates to the field of welding equipment, and in particular to an intelligent welding device for bed frame processing. Background Technology

[0002] The bed is supported by a bed frame, on which the mattress is placed. The bed frame is generally welded to ensure overall load-bearing capacity. The bed frame consists of side tubes and cross tubes. There can be one side tube on each side, and multiple cross tubes are arranged in parallel. The cross tubes and side tubes are welded together using a welding device to form the complete bed frame.

[0003] Currently, when installing pipe fittings, the side pipes are typically installed first, clamped with fixtures, and then multiple horizontal pipes are clamped between the two side pipes to avoid large gaps between the ends of the horizontal pipes and the side pipes, thus preventing any impact on the subsequent welding quality. However, this clamping installation method requires aligning each horizontal pipe precisely; even slight deviations in operation can lead to inaccurate clamping, wasting time and affecting installation efficiency. After the bed frame is welded, the clamps on the side pipes need to be manually released, and then the entire bed frame needs to be removed vertically upwards, a cumbersome operation. Summary of the Invention

[0004] The purpose of this invention is to address the problems existing in the background art by proposing an intelligent welding device for bed frame processing, which simplifies the placement of pipes, increases placement efficiency, and facilitates the removal of the welded bed frame.

[0006] Preferably, the roller support assembly includes a second mounting base on the machine tool body, a first roller frame on the top of the second mounting base, and two roller bodies rotatably mounted side by side on the first roller frame. Vertical rods are vertically slidably mounted on the first roller frame. Multiple vertical rods are arranged side by side, including first vertical rod and second vertical rod. Two second vertical rods are symmetrically distributed about the first vertical rod. First vertical rod and second vertical rod are evenly connected to the bottom of the pressure plate.

[0007] Preferably, the lifting mechanism includes a lifting mechanism vertically mounted on the mounting base 2 and a support platform mounted at the top of the lifting mechanism, the support platform being located below the limiting roller.

[0008] Preferably, the elastic limiting plate is disposed on the second mounting base and is a U-shaped plate structure that tapers inward in the middle and has a V-shaped distribution at the top.

[0009] Preferably, when the limiting roller moves down to its limit position, the limiting roller contacts the support platform, the two sets of roller clamping mechanisms move inward and clamp the rollers on both sides of the horizontal tube, and when the limiting roller moves up to the upper V-shaped part of the elastic limiting plate, the top surface of the base frame contacts the bottom surface of the roller frame, and the two sets of roller clamping mechanisms unfold outward and disengage from the horizontal tube.

[0010] Preferably, when the limiting roller moves down to its limit position, the height of the top of the pressure plate is lower than the height of the top of the roller body.

[0011] Preferably, the roller clamping mechanism further includes a bracket mounted on the mounting base two, a rotating frame rotatably mounted on the bracket, and a roller clamping assembly mounted on the bracket, with a push plate mounted on the rotating frame.

[0012] Preferably, the roller clamp assembly includes a second roller frame, multiple second rollers arranged side-by-side and rotatably on the second roller frame, a pressure sensor and an anti-detachment rod arranged on the second roller frame, a mounting plate for sliding installation of the anti-detachment rod and abutting against the pressure sensor, and a translation plate located between the mounting plate and the rotating frame. The rotating frame is provided with a spacing adjustment component for adjusting the distance between the translation plate and the rotating frame, and the translation plate is provided with an angle adjustment component for adjusting the inclination of the mounting plate relative to the translation plate. The machine tool body integrates a central controller, and the pressure sensor is communicatively connected to the central controller.

[0015] Compared with existing technologies, this invention has the following beneficial technical effects: This invention makes pipe placement easier. First, two side tubes are placed in position, then the remaining horizontal tubes are roughly placed in the middle. The positioning mechanism automatically clamps the horizontal tubes, making pipe placement simpler and more efficient. Subsequently, the aligning assembly pushes the side tubes inward, causing the two side tubes to move towards each other, aligning the multiple horizontal tubes so that both ends of the horizontal tubes abut against the inner surfaces of the two side tubes. After welding, the entire bed frame can be lifted, using multiple pressure plates to support it, facilitating removal of the bed frame. Attached Figure Description

[0018] Example 1: As Figures 1-9 As shown in the figure, the intelligent welding device for bed frame processing proposed in this embodiment includes a machine tool body 1 and a clamping device.

[0019] The upper part of the machine tool body 1 is equipped with a three-dimensional adjustment module 3, and the moving end of the three-dimensional adjustment module 3 is equipped with a welding head 2. The machine tool body 1, the welding head 2 and the three-dimensional adjustment module 3 all adopt existing mature structures. According to the clamping position of the horizontal tube and the side tube of the bed frame, the three-dimensional adjustment module 3 adjusts the position of the welding head 2 to perform intelligent welding on the contact part of the horizontal tube and the side tube. The welding head 2 can be a laser welding head, which has high welding efficiency.

[0020] like Figure 2 and Figure 3 As shown, the clamping device includes four sets of rectangularly distributed side positioning components 4, multiple sets of support positioning mechanisms 5 arranged in an array between the four sets of side positioning components 4, and two sets of symmetrically distributed push-aligning components 6. The support positioning mechanism 5 is used to clamp the horizontal tube with rollers.

[0021] like Figures 1-5As shown, two sets of side positioning components 4 on the same side are aligned and clamped at both ends of the side tube along its length, thus aligning and clamping the side tubes. A total of two side tubes can be aligned and clamped. Subsequently, the alignment component 6 is used to align the side tubes and the horizontal tube. The side positioning component 4 includes a mounting base 41 mounted on the machine tool body 1, a guide rail 42 horizontally mounted on top of the mounting base 41, a slider 43 slidably mounted on the guide rail 42, a spring 44 located between the slider 43 and one end of the guide rail 42, a connecting seat 45 mounted on the slider 43, a positioning element 46 rotatably mounted on the connecting seat 45, and a limiting platform 47 mounted on the connecting seat 45 and limiting the external rotation range of the positioning element 46. The positioning component 46 includes a positioning plate portion 461, a support plate portion 462 vertically connected to the lower part of the positioning plate portion 461, a counterweight plate portion 463 integrally connected to the top of the positioning plate portion 461, and a baffle portion 464 disposed on the side of the positioning plate portion 461. The baffle portion 464 is inclined upward on the bottom surface facing the support plate portion 462. Figure 5 As shown, the center of gravity of the positioning component 46 is located on one side of the limiting platform 47. When the side tube is not clamped, the positioning plate portion 461 is in contact with the top of the limiting platform 47. Figure 4 As shown, when placing the side tube, the two ends of the side tube are pressed onto the two support plates 462 in the two sets of side positioning components 4 respectively. The side tube pushes down the support plates 462, the positioning member 46 rotates inward, the positioning plate 461 contacts the end of the side tube, and the baffle 464 is located inside the end of the side tube.

[0022] The supporting and positioning mechanism 5 includes a roller support assembly, two symmetrically distributed sets of roller clamping mechanisms, and a triggering assembly that drives the upper parts of the two sets of roller clamping mechanisms to move inward or outward. The triggering assembly includes a vertical rod, pressure plates 54 and a base frame 57 respectively set at the top and bottom of the vertical rod, two side rods 58 symmetrically set on the base frame 57, a sliding roller 581 set on the side rods 58, a limiting roller 59 set at the bottom of the base frame 57, an elastic limiting plate 510 that limits the position of the limiting roller 59, and a lifting mechanism for lifting the limiting roller 59. When placing the horizontal tube, it is positioned on the two supporting and positioning mechanisms 5 between the two side tubes. The horizontal tube presses down on the pressure plate 54, which in turn moves the vertical rod, base frame 57, side rods 58, sliding rollers 581, and limiting rollers 59 downwards. The sliding rollers 581 cause the roller clamping mechanism to rotate inwards, and the two sets of roller clamping mechanisms move inwards, clamping the horizontal tube on both sides. The elastic limiting plate 510 blocks the limiting rollers 59 on the inside, ensuring that the roller clamping mechanism has sufficient clamping force on the horizontal tube. When the lifting mechanism lifts the limiting rollers 59, the limiting rollers 59 move upwards through the base frame 57, causing the side rods 58 and sliding rollers 581 to move upwards. The sliding rollers 581 then cause the roller clamping mechanism to unfold outwards, releasing the clamping force on the horizontal tube.

[0023] like Figure 6 and Figure 7As shown, the roller support assembly includes a second mounting base 51 mounted on the machine tool body 1, a first roller frame 52 mounted on top of the second mounting base 51, and two roller bodies 53 rotatably mounted side-by-side on the first roller frame 52. Vertical rods are vertically slidably mounted on the first roller frame 52. Multiple vertical rods are arranged side-by-side, including first vertical rod 55 and second vertical rod 56. Two second vertical rods 56 are symmetrically distributed about first vertical rod 55. First vertical rod 55 and second vertical rod 56 are evenly connected to the bottom of the pressure plate 54, ensuring balanced force distribution.

[0024] like Figure 6 As shown, the lifting mechanism includes a lifting mechanism 512 vertically mounted on the mounting base 51 and a support platform 511 located at the top of the lifting mechanism 512, below the limiting roller 59. When the limiting roller 59 moves to its extreme position, it contacts the support platform 511. The lifting mechanism 512 uses a hydraulic cylinder or an electric cylinder. During subsequent lifting of the limiting roller 59, the lifting mechanism 512 extends, lifting the limiting roller 59 via the support platform 511. The support platform 511 has an arc-shaped groove that matches the outer circumferential surface of the limiting roller 59, resulting in a more suitable structure.

[0025] like Figure 6 As shown, the elastic limiting plate 510 is set on the mounting base 51. It is a U-shaped plate structure that tapers inward in the middle and has a V-shaped distribution at the top. The elastic limiting plate 510 can be made of metal plate, which can deform to a certain extent and reset, thereby limiting the limiting roller 59.

[0026] When the limiting roller 59 moves down to its limit position, it contacts the support platform 511, and the two sets of roller clamping mechanisms move inward and clamp the rollers on both sides of the horizontal tube. When the limiting roller 59 moves up to the upper V-shaped part of the elastic limiting plate 510, the top surface of the base frame 57 contacts the bottom surface of the roller frame 52, and the two sets of roller clamping mechanisms unfold outward and disengage from the horizontal tube.

[0027] When the limiting roller 59 moves down to its limit position, the top height of the pressure plate 54 is lower than the top height of the roller body 53. When the pressure plate 54 is pressed down by the horizontal tube, the pressure plate 54 pushes the elastic limiting plate 510 downward from the upper V-shaped part of the elastic limiting plate 510. When the limiting roller 59 passes through the middle contraction area from top to bottom of the elastic limiting plate 510, the elastic limiting plate 510 squeezes the limiting roller 59. The limiting roller 59 drives the pressure plate 54 to move down through the base frame 57 and the vertical rod, and the pressure plate 54 disengages from the horizontal tube. When the horizontal tube moves down onto the roller body 53, the pressure plate 54 reaches a position lower than the roller body 53 (see...). Figure 7 This is to prevent sliding contact wear between the pressure plate 54 and the horizontal tube when aligning the horizontal tube laterally.

[0028] The roller clamping mechanism includes a support plate 515 with a slide rail 5151, a bracket 513 mounted on a mounting base 51, a rotating frame 514 rotatably mounted on the bracket 513, and roller clamping assemblies mounted on the bracket 513. The support plate 515 is mounted on the rotating frame 514, and the sliding roller 581 is slidably mounted at the slide rail 5151. When the sliding roller 581 moves up or down, the movement of the sliding roller 581 at the slide rail 5151 drives the support plate 515 to rotate, which in turn drives the rotating frame 514 to rotate, thereby realizing the rotation of the roller clamping assembly and thus enabling the two sets of roller clamping assemblies to move closer or further apart. Specifically, when the sliding roller 581 moves down, it drives the support plate 515 to rotate downward, causing the two sets of roller clamping assemblies to move closer together; when the sliding roller 581 moves up, it drives the support plate 515 to rotate upward, causing the two sets of roller clamping assemblies to move further apart.

[0029] like Figures 1-5 As shown, the alignment assembly 6 includes a mounting base 3 61 mounted on the machine tool body 1 and a telescopic mechanism 62 horizontally mounted on the mounting base 3 61. The telescopic mechanism 62 uses a hydraulic cylinder or an electric cylinder. A push plate is installed at the front end of the telescopic mechanism 62, which can push the side tubes towards the end of the horizontal tube. During this process, the side tubes drive the entire positioning component 46 to move through the stop part 464. The positioning component 46 drives the connecting seat 45 and the slider 43 to slide, and the slider 43 compresses the spring 44. The two telescopic mechanisms 62 push the two side tubes on both sides respectively, and finally use the side tubes to push the horizontal tube to move on the supporting positioning mechanism 5. The horizontal tube moves on the roller body 53. The roller body 53 and the horizontal tube are in rolling contact, which does not affect the lateral movement of the horizontal tube. The roller clamp assembly and the horizontal tube are also in rolling contact. Until the two ends of the horizontal tube are aligned and abut against the inner surfaces of the two side tubes respectively, the horizontal tube and the side tube are properly positioned. Then, the position of the welding head 2 is adjusted by the three-dimensional adjustment module 3. Within the working range of the welding head 2, the welding head 2 is used to weld the contact parts of the horizontal tube and the side tube. After welding is completed, the telescopic mechanism 62 retracts, the lifting mechanism 512 pushes the limiting roller 59 up through the support platform 511, and the multiple pressure plates 54 push the welded bed frame up. The side tube part uses the inclined bottom surface of the baffle part 464 to push the positioning part 46 outward, so that the positioning part 46 will not obstruct the upward movement of the bed frame.

[0030] This embodiment makes pipe placement easier. First, the two side pipes are placed in position, and then the remaining horizontal pipes are roughly placed in the middle. The placement of the horizontal pipes does not need to be too precise; simply place them horizontally at the support and positioning mechanism 5 between the two side pipes. The support and positioning mechanism 5 automatically clamps the horizontal pipes with rollers. Compared with traditional pipe placement methods, the placement operation in this embodiment is simpler and more efficient. Subsequently, the side pipes are pushed inward using the alignment component 6, and the two side pipes move towards each other, aligning the roughly placed horizontal pipes so that the ends of the horizontal pipes abut against the inner surfaces of the two side pipes. Finally, the welding head 2 is used to weld the abutment parts, resulting in a bed frame with high welding quality. After welding, the entire bed frame can be lifted, and multiple pressure plates 54 are used to support the bed frame, making it easy to remove.

[0031] Example 2: Figures 1-9 As shown, this embodiment proposes an intelligent welding device for bed frame processing. Compared to Embodiment 1, in this embodiment, the roller clamp assembly includes a second roller frame 523, multiple second rollers 524 arranged side-by-side and rotatably on the second roller frame 523, a pressure sensor 525 and an anti-detachment rod 526 arranged on the second roller frame 523, a mounting plate 519 for sliding installation of the anti-detachment rod 526 and abutting against the pressure sensor 525, and a translation plate 516 located between the mounting plate 519 and the rotating frame 514. The end of the anti-detachment rod 526 away from the second roller frame 523 has an anti-detachment platform, which allows the pressure sensor 525 to abut against the mounting plate 519. When the roller clamp assembly clamps the side of the horizontal tube, the clamping is specifically performed by the second rollers 524. There is rolling contact between the horizontal tube and the second rollers 524. The horizontal tube can move accurately laterally between the first roller 53 and the second roller 524 to abut the two ends of the horizontal tube against the two side tubes on both sides.

[0032] The rotating frame 514 is equipped with a spacing adjustment component to adjust the distance between the translation plate 516 and the rotating frame 514. The translation plate 516 is equipped with an angle adjustment component to adjust the tilt of the mounting plate 519 relative to the translation plate 516. The machine tool body 1 integrates a central controller. The pressure sensor 525 is connected to the central controller for communication. The central controller is connected to the lifting mechanism 512 and the telescopic mechanism 62 for control. When the pressure data detected by the pressure sensor 525 is within a preset threshold, it indicates that the force of the roller body 524 clamping on the horizontal tube is appropriate, thereby realizing intelligent monitoring of the horizontal tube clamping effect. When the clamping force is appropriate, the central controller controls the three-dimensional adjustment module 3 and the welding head 2 to weld the contact parts of the horizontal tube and the side tube.

[0033] like Figure 8As shown, the spacing adjustment assembly includes a slide rod 517 mounted on a translation plate 516 and slidably connected to a rotating frame 514, and a threaded knob 518 rotatably connected to the translation plate 516 and threadedly connected to the rotating frame 514. Rotating the threaded knob 518 moves the translation plate 516, guided by the slide rod 517. This adjusts the spacing between the two sets of roller clamp assemblies when they are closed, thus enabling the clamping of rectangular horizontal tubes of different widths (see...). Figure 3 ), or use roller clamps for triangular horizontal tubes of different sizes (see Figure 9 ).

[0034] like Figure 8 As shown, the angle adjustment assembly includes a hinge that hinges the lower part of the translation plate 516 and the lower part of the mounting plate 519, a hinge platform 520 hinged to the upper part of the mounting plate 519, a threaded sleeve 521 rotatably mounted on the translation plate 516, and a threaded knob 522 rotatably connected to the hinge platform 520 and threadedly connected to the threaded sleeve 521. By rotating the threaded knob 522, the mounting plate 519 can be rotated via the hinge platform 520, adjusting the angle of the mounting plate 519, and thereby adjusting the angles of the roller frame 523 and the roller body 524 to adapt to the roller clamping of rectangular or triangular horizontal tubes.

[0035] In addition, the sliding roller 581 slides at the slide rail 5151, and may wear out after prolonged use, resulting in a decrease in the linkage accuracy of the sliding roller 581 driving the push plate 515 to rotate. At this time, fine adjustments can be made to the spacing adjustment component and the angle adjustment component to ensure that the two sets of roller clamping components can still be clamped on both sides of the horizontal tube when they are closed, thereby improving the adaptability of the support and positioning mechanism 5 and extending the service life of the support and positioning mechanism 5.

[0036] This embodiment can clamp the horizontal tube using roller body 524, and can adjust the position and angle of roller body 524 to clamp horizontal tubes of different sizes and shapes, thus having a wide range of applications.

[0037] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited thereto. Various changes can be made within the scope of knowledge possessed by those skilled in the art without departing from the spirit of the present invention.
