Technical Field
[0001] This invention relates to the field of industrial composite door welding technology, and in particular to an automatic processing equipment and processing method for industrial composite door structures. Background Technology
[0002] As a key component of modern industrial buildings and large-scale facilities, industrial composite doors have the core functions of defining space, ensuring safety, maintaining a specific environment, and enabling efficient logistics passage. With the rapid improvement of industrial automation, logistics efficiency, and building energy conservation requirements, traditional industrial doors made of single materials can no longer meet the increasingly stringent composite requirements in terms of strength, weight, durability, and overall performance. Therefore, industrial composite doors have emerged and become the mainstream direction of technological development in this field. The internal support frame of an industrial composite door is the "skeleton" and "core" of the entire door system, and its performance directly determines the structural strength, dimensional stability, service life, and installation accuracy of the door.
[0003] Existing industrial composite door inner frames require manual welding or mechanical welding after fixing the workpiece with various complex fixtures. Workers waste a lot of time fixing the workpiece, and after welding one side, it needs to be flipped for welding, requiring multiple workers to cooperate to flip it. Therefore, this application provides an automatic processing equipment and processing method for industrial composite door structures to meet the requirements. Summary of the Invention
[0004] The technical problem to be solved by the present invention is to provide an automatic processing equipment and processing method for industrial composite door structures to solve the problem that the existing industrial composite door inner frame needs to be manually welded or mechanically welded after the workpiece is fixed by various complex fixtures.

[0010] Optionally, the inner clamping unit includes two inner baffles that fit against the inner angles of the short rod and the long rod to be welded after splicing.

[0014] This application also provides a processing method for an automated processing equipment for industrial composite door structures, which includes the following steps: S1.

[0015] Compared with the prior art, the present invention has at least the following beneficial effects: In the above solution, by setting up a short rod fixing component, a long rod fixing component, and a corner fixing component, the short rod fixing component and the long rod fixing component respectively limit the long rod and the short rod to be welded, and then the corner fixing component limits and fixes the connection position after the long rod and the short rod are spliced together, ensuring the stability between the long rod and the short rod during welding. At the same time, the method of installing the long rod and the short rod is simple, and it is also easy to disassemble after welding.
[0016] By setting up a first pull rod and a second pull rod, when adjusting the position of the inner baffle, the second vertical plate can be adjusted synchronously through the first and second pull rods, so that the inner side of the second vertical plate is at the same level as the inner baffle. This eliminates the need for staff to adjust the position of the long rod fixing component separately, saving operation time and increasing the positional accuracy of the long rod fixing component.
[0017] By setting up a rotating bar, the support plate and the third vertical plate can be rotated, which can achieve quick self-locking of the long rod during installation. At the same time, when welding is completed and disassembly is required, the workpiece can be quickly unloaded by squeezing the rotating bar. Attached Figure Description

[0027] like Figures 1 to 11As shown, an embodiment of the present invention provides an automatic processing equipment for industrial composite door structures, including two symmetrically arranged bases 1. A drive device 2 is installed on the top of the base 1, and a welding arm 3 is arranged at the middle position of the base 1. The bases 1, drive devices 2, and welding arms 3 are all prior art. A welding frame assembly 4 is installed between the two drive devices 2. The welding frame assembly 4 includes a first rotating frame 41 fixedly connected to the drive device 2. Both ends of the first rotating frame 41 are fixedly connected to the drive device 2. The rotation of the first rotating frame 41 is driven by the rotation of the output end of the drive device 2. A slide 42 is slidably connected to the first rotating frame 41. A second rotating frame 43 is rotatably connected inside the slide 42. The inner wall of the second rotating frame 43 is fixedly connected to... The cross 44 slides on the first rotating frame 41 via the slide 42, allowing for the disassembly of the second rotating frame 43 and the cross 44, facilitating routine maintenance and repair. Two short rod fixing components 5 are connected to the cross 44 and are used to limit the short rods to be welded. Two long rod fixing components 7 are located on the cross 44 and connected to it, and are used to limit the long rods to be welded. Two corner fixing components 6 are located on the cross 44 and connected to it, and are used to limit the edges where the long and short rods are joined.
[0028] When welding the inner frame of the composite door structure is required, the two short inner frame rods to be welded are placed on the two short rod fixing components 5 respectively, and the two long inner frame rods to be welded are placed on the two long rod fixing components 7 respectively. By adjustment, the adjacent ends of the long rods and short rods are made to fit together, so that they form a frame structure with the ends connected. Finally, the corner fixing components 6 limit the four edge corners. After the limiting and fixing are completed, the welding arm 3 is used to weld and fix the connection position of the long rods and short rods. When one side is welded, the first rotating frame 41 is rotated 180° by the driving device 2, so that the welding arm 3 can weld and fix the other side.
[0029] like Figure 3 As shown, the first rotating frame 41 has a U-shaped structure with an opening on one side. The three inner sides of the first rotating frame 41 are provided with interconnected frame slide grooves 411. The slide 42 has three corresponding limiting strips 421 on its three sides that are adapted to it. The U-shaped first rotating frame 41 can allow the slide 42 to be completely pulled out from the opening. The two ends of the slide 42 are provided with locking blocks. The corresponding positions of the frame slide grooves 411 are provided with locking slots that are adapted to it. The locking blocks and locking slots are existing technologies. The first rotating frame 41 and the slide 42 can be detached by the cooperation of the locking blocks and locking slots.
[0030] like Figures 3 to 5As shown, the cross 44 is formed by connecting two symmetrical short segments 442 and two symmetrical long segments 443 into a cross shape. The cross 44 is an integrally formed structure. The cross 44 provides installation positions for the short rod fixing assembly 5, the corner fixing assembly 6, and the long rod fixing assembly 7. At the same time, it positions the fixed long rod and short rod below the welding arm 3, which facilitates welding of the welding arm 3. The outer ends of the two short segments 442 and the two long segments 443 are respectively fixedly connected to the four inner walls of the second rotating frame 43. A through first groove 444 is opened in the middle of the long segment 443. Symmetrical second grooves 445 are opened on both sides of the long segment 443 near the first groove 444. A ball screw 441 is installed at the bottom of the long segment 443 near the first groove 444. A third groove 446 is opened in the middle of the short segment 442.
[0031] like Figure 4 and Figure 11 As shown, the short rod fixing assembly 5 includes two first base plates 51 that fit against the bottom of the long section 443. The two ends of the first base plates 51 are fixedly connected to first connecting plates 52. The top of the first connecting plates 52 is fixedly connected to a first vertical plate 53. The top of the first vertical plate 53 is fixedly connected to a first limiting strip 54, which is a concave elastic structure. The first connecting plate 52 is located inside the second sliding groove 445 and is slidably connected to the second sliding groove 445. The length of the first connecting plate 52 is the same as the thickness of the long section 443. The distance between the two first vertical plates 53 is the same as the width of the short rod to be welded. The distance between the first limiting strip 54 and the surface of the long section 443 is the same as the height of the short rod to be welded.
[0032] When it is necessary to fix the short rod to be welded, the bottom of the short rod is pressed from the top of the first limiting strip 54. When pressed, the first limiting strip 54 is elastic and shifts outward after being subjected to the compressive force, so that the short rod can be inserted between the two first vertical plates 53 until the bottom of the short rod is in contact with the bottom of the cross 44. The first limiting strip 54 returns to the initial position to limit the top of the short rod. The worker can slide on the second slide groove 445 by moving the short rod fixing component 5.
[0033] like Figures 4 to 8 As shown, the fixed angle assembly 6 includes a screw slider 61 sleeved on the screw nut of the ball screw 441. The position adjustment of the screw slider 61 can be controlled by the ball screw 441. Telescopic rods 62 are fixedly connected to both sides of the screw slider 61. The telescopic rods 62 are installed at a 45° angle with the screw slider 61. An inner locking unit 63 is connected to the end of the telescopic rod 62 away from the screw slider 61. An adjustment unit 64 is connected to the inner locking unit 63. An outer locking unit 65 is connected to the top of the adjustment unit 64.
[0034] The inner clamping unit 63 includes two inner baffles 631 that fit against the inner angles of the short rod and the long rod to be welded after splicing. A first connecting rod 632 is fixedly connected to the opposite sides of the two inner baffles 631. An adjusting groove 633 is provided through the middle of the first connecting rod 632. The two inner baffles 631 are distributed at right angles to each other. The adjusting unit 64 includes an adjusting rod 641 that is slidably connected to the adjusting groove 633. A sleeve 642 and an anti-detachment block are fixedly connected to both ends of the adjusting rod 641, respectively. The outer clamping unit 65 includes a component that is rotatably connected to the sleeve 642. The upper adjusting rod 654 has a second connecting rod 652 fixedly connected to its top. The two ends of the second connecting rod 652 are fixedly connected to outer baffles 653. The inner side of the outer baffles 653 is fixedly connected to several evenly distributed rubber strips 651. The rubber strips 651 prevent the long rod and short rod in contact with them from having relative displacement. At the same time, the deformation effect of the rubber strips 651 can avoid the problem of gaps between the outer baffles 653 and the long rods and short rods, which would lead to poor limiting effect. The two outer baffles 653 are distributed at right angles to each other.
[0035] When placing the long and short rods to be welded, determine the positions of the two inner baffles 631 on the inner clamping unit 63 according to the frame formed by splicing the long and short rods. By adjusting the position of the screw slider 61 on the ball screw 441 and the length of the telescopic rod 62, the two inner baffles 631 are positioned to fit against the inner sides of the adjacent long and short rods. Once the positions of the inner baffles 631 are determined, they remain unchanged. When splicing the long and short rods, place the two long rods tightly against the upper and lower inner baffles 631 respectively, so that the two long rods are in a parallel state. Then, place the short rods on the short rod fixing assembly 5, and adjust the position between the two short rods by sliding the short rod fixing assembly 5. The two ends of the short rod are aligned with one end of each of the two long rods, thus achieving the initial splicing between the two long rods and the two short rods. After the long rods and short rods are spliced and aligned, the outer clamping unit 65 is pulled, causing the adjusting rod 641 to slide on the adjusting groove 633 until the outer baffle 653 is located above the splicing point of the long rods and short rods. Then, the second connecting rod 652 is pressed, causing the two outer baffles 653 to engage with the outer edge of the splicing point of the long rods and short rods, thereby fixing the outer side of the splicing point. Through the mutual cooperation of the two inner baffles 631 and the two outer baffles 653, the splicing point of the long rods and short rods is limited both internally and externally, thus keeping the spliced long rods and short rods relatively fixed and preventing displacement.
[0036] like Figure 4 , Figure 9 and Figure 10As shown, the long rod fixing assembly 7 includes a second base plate 73 located at the bottom of the third slide groove 446. A second connecting plate 72 is fixedly connected to the top of the second base plate 73, and a second vertical plate 71 is fixedly connected to the top of the second connecting plate 72. The top of the second vertical plate 71 has an arc-shaped surface, which facilitates the placement of the long rod to be welded by the worker. The second vertical plate 71 and the second connecting plate 72 are located on both sides of the third slide groove 446, respectively. Through the cooperation of the second vertical plate 71, the second connecting plate 72 and the second base plate 73, the long rod fixing assembly 7 can slide on the third slide groove 446. A rotating rod 74 is fixedly connected to both ends of the second base plate 73. A rotating strip 75 is sleeved on the outer wall of the rotating rod 74. A support plate 77 and a third vertical plate 76 are fixedly connected to both ends of the rotating strip 75, respectively. Both ends of the second vertical plate 71 are fixed. A first pull rod 78 is connected, and a pull rod groove 781 is opened on one side of the first pull rod 78. A second pull rod 79 is slidably connected to the pull rod groove 781. One end of the second pull rod 79 is fixedly connected to the inner baffle 631. When the position of the inner baffle 631 is adjusted, the two opposing inner baffles 631 will drive the second pull rod 79 to slide on the first pull rod 78 when they are displaced. Then, the first pull rod 78 drives the entire long rod fixing assembly 7 to move. After the position of the inner baffle 631 is adjusted, the second vertical plate 71 is adjusted synchronously by the first pull rod 78 and the second pull rod 79 so that the inner side of the second vertical plate 71 is at the same level as the inner baffle 631. There is no need for the staff to adjust the position of the long rod fixing assembly 7 separately, which saves operation time and increases the positional accuracy of the long rod fixing assembly 7.
[0037] The rotating bar 75 has a herringbone structure, and its width is the same as the width of the third chute 446. The support plate 77 and the third vertical plate 76 are distributed at right angles. When the third vertical plate 76 and the second vertical plate 71 are in a parallel position, the distance between the second vertical plate 71 and the third vertical plate 76 is the same as the width of the long rod. The top of the third vertical plate 76 is fixedly connected to the second limiting strip 761, which is an elastic structure. An airbag device 8 is fixedly connected to the bottom middle position of the cross 44. The two output ends of the airbag device 8 are fixedly connected to the bottom of the support plate 77. The airbag device 8 is existing technology. After the long rod and the short rod are spliced and welded, the output end of the airbag device 8 squeezes the support plate 77, thereby driving the rotating bar 75 to rotate. Under the continuous squeezing force, the welded long rod is squeezed out from the long rod fixing assembly 7, thereby realizing the self-unloading of the workpiece without causing squeezing damage to the workpiece.
[0038] In the initial state, the third vertical plate 76 is flipped outward. When the long rod to be welded needs to be placed, the bottom of the long rod is aligned with the space between the second vertical plate 71 and the third vertical plate 76 and slid in. The bottom of the long rod contacts the support plate 77. Under the continuous pressure of the long rod, the pressure at the bottom of the long rod drives the rotating bar 75 to rotate on the rotating rod 74 until the bottom of the long rod is completely in contact with the support plate 77. Since the support plate 77 and the third vertical plate 76 are distributed at right angles, when the bottom of the long rod presses the support plate 77 into a horizontal position, the inner side of the third vertical plate 76 is just in contact with the long rod. At the same time, the second limiting bar 761 limits the top of the long rod, so that the long rod is limited and fixed between the second vertical plate 71 and the third vertical plate 76.
[0039] This application also provides a processing method for an automated processing equipment for industrial composite door structures, which includes the following steps: S1. Determine the positions of the two inner baffles 631 on the inner clamping unit 63 according to the frame formed by splicing the long rod and the short rod. When adjusting the inner baffles 631, adjust the position of the long rod fixing component at the same time. S2. Place the two inner frame short rods to be welded on the two short rod fixing components 5 respectively, and place the two inner frame long rods to be welded on the two long rod fixing components 7 respectively. S3. Adjust the outer clamp unit 65, which, through the cooperation of the two inner baffles 631 and the two outer baffles 653, limits the inner and outer movement of the joint between the long rod and the short rod. S4. After the long rod and short rod to be welded are fixed in place, the connection position of the long rod and short rod is welded and fixed by welding arm 3.
[0040] The working principle of the technical solution provided by the present invention is as follows: When the inner frame of the composite door structure needs to be welded, the positions of the two inner baffles 631 on the inner card unit 63 are determined according to the frame formed by splicing long rods and short rods. By adjusting the position of the screw slider 61 on the ball screw 441 and the length of the telescopic rod 62, the two inner baffles 631 are just located in contact with the inner side of the adjacent long rods and short rods. After the position of the inner baffles 631 is determined, it remains unchanged. Then the long rods and short rods to be welded are placed.
[0041] When placing the short rods to be welded, the two inner frame short rods to be welded are placed on the two short rod fixing components 5 respectively. During placement, the bottom of the short rod is pressed from the top of the first limiting strip 54. When pressed, the first limiting strip 54 is elastic and shifts outward after being subjected to the pressing force, so that the short rod can be inserted between the two first vertical plates 53 until the bottom of the short rod is in contact with the bottom of the cross 44. The first limiting strip 54 returns to its initial position to limit the top of the short rod. The operator can slide on the second slide groove 445 by moving the short rod fixing component 5.
[0042] When placing the long rods to be welded, place the two inner frame long rods to be welded on the two long rod fixing components 7 respectively, and slide the bottom of the long rod between the second vertical plate 71 and the third vertical plate 76. The bottom of the long rod contacts the support plate 77. Under the continuous pressing of the long rod, the pressure at the bottom of the long rod drives the rotating bar 75 to rotate on the rotating rod 74 until the bottom of the long rod is completely in contact with the support plate 77. Since the support plate 77 and the third vertical plate 76 are distributed at right angles, when the bottom of the long rod presses the support plate 77 into a horizontal position, the inner side of the third vertical plate 76 is just in contact with the long rod. At the same time, the second limiting bar 761 limits the top of the long rod, so that the long rod is limited and fixed between the second vertical plate 71 and the third vertical plate 76.
[0043] After the long and short rods to be welded are placed and spliced, pull the outer clamping unit 65 to make the adjusting rod 641 slide on the adjusting groove 633 until the outer baffle 653 is above the splice of the long and short rods. Then press the second connecting rod 652 so that the two outer baffles 653 are inserted into the outer edge of the splice of the long and short rods, thereby fixing the outer side of the splice. Through the cooperation of the two inner baffles 631 and the two outer baffles 653, the splice of the long and short rods is limited inside and outside, thereby keeping the spliced long and short rods relatively fixed and preventing displacement.
[0044] After the long and short rods to be welded are fixed in place, the welding arm 3 welds and fixes the connection position of the long and short rods. After one side is welded, the drive device 2 drives the first rotating frame 41 to rotate 180°, so that the welding arm 3 can weld and fix the other side. Finally, the outer clamping unit 65 is pulled out, and the output end of the airbag device 8 squeezes the support plate 77, thereby driving the rotating bar 75 to rotate. Under the continuous squeezing force, the welded long rod is squeezed out from the long rod fixing assembly 7, thereby realizing the self-unloading of the workpiece.
