Description

Technical Field

[0001] This invention relates to the field of metal welding equipment technology, specifically to a seamless welding equipment for door leaf production. Background Technology

[0002] In door leaf manufacturing, welding is a crucial process ensuring the structural strength, sealing performance, and smoothness of the door leaf. Welding technology is widely used in the connection and processing of door leaf frames, reinforcing ribs, and joints. With the construction industry's increasing demands for door and window product quality, seamless welding has become a core technological requirement for door leaf production. Welding technologies such as arc welding, resistance welding, and laser welding are gradually being applied in door leaf production, achieving metallurgical bonding between the welding material and the door leaf substrate through high-temperature melting, thus meeting basic connection strength requirements.

[0003] Authorization announcement number CN118650324B discloses a turning machine for welding the door leaf of a suspended door, relating to the technical field of welding. The machine includes a frame with a welding arm for welding the door leaf mounted on top. Motors symmetrically distributed along the frame are fixedly connected to the top of the frame. A fixed frame is fixedly connected between the output shafts of the symmetrically distributed motors. Fixed plates symmetrically distributed along the fixed frame are fixedly connected to the fixed frame, and a rotating frame is rotatably connected between the symmetrically distributed fixed plates. During turning, the support plates can always share a certain weight of the door leaf, enhancing operational safety. Furthermore, the movement of the sliding clamps can accommodate door leaves of different sizes. The sliding clamps on all four sides can firmly fix the door leaf, ensuring the accuracy of the position before and after turning, reducing positional deviations caused by manual operation, improving the alignment accuracy of the welding points, and ensuring consistent welding quality. However, this invention requires turning the door leaf when welding the bottom. Although the support plates provide some support during turning, there are still certain safety hazards during the turning process, and the uneven stress on the welding points during turning can easily lead to breakage.

The welding mechanism includes a welding main frame, a door frame positioning mechanism, and a flue gas purification mechanism. The door frame positioning mechanism is fixedly connected to the welding main frame, and the flue gas purification mechanism is fixedly connected to the welding main frame. The fastening and sliding mechanism includes a sliding frame and a fastening frame. The fastening frame is fixedly connected to the sliding frame and can slide on the sliding frame. The sliding frame is fixedly connected to the welding main frame and can slide on the welding main frame. The slitting mechanism is fixedly connected to the welding main frame. In this invention, after the upper part of the door panel is welded, the door panel needs to be flipped over by a lifting tool, which reduces the welding efficiency of the door panel. Summary of the Invention

[0006] To achieve the above objectives, the present invention provides the following technical solution: a seamless welding equipment for door leaf production, comprising: a frame, wherein a support mechanism for supporting the door leaf is installed inside the frame, the support mechanism including a main support component for supporting the bottom edge of the door leaf and an auxiliary support component for supporting the center of the bottom of the door leaf, welding mechanisms are installed at the top and bottom of the frame, and the welding mechanisms at the top and bottom can respectively weld the upper part and the bottom of the door leaf through the cooperation of the support mechanism; the main support component includes a movable structure and a support base.

[0007] The moving structure includes a chute and a sliding frame. Two chutes are symmetrically opened on each inner side of the frame. Each chute has a first sliding seat installed inside it via a drive component to drive the support seat to move laterally. When the support seat moves horizontally along the opening of the chute, it can make way for the position where the welding mechanism needs to weld.

Each of the two support seats has a connecting rod in opposite directions on its upper part. A third slide is movably installed inside the connecting rod via a driving component. The third slide has a correction block. The two correction blocks can move towards each other to correct and align the two ends of the door frame.

[0011] Preferably, the main support assembly further includes a positioning assembly, which includes a first cylinder and a positioning plate. The first cylinder is fixedly installed on the support base, and the positioning plate is installed at the output end of the first cylinder through an elastic element. The bottom of the positioning plate is movably installed on the upper surface of the support base. When the first cylinder is working, it can push the positioning plate to move horizontally along the upper surface of the support base. When the positioning plate moves horizontally, it can position the side of the door frame.

[0012] Preferably, a height adjustment part is installed at one end of the connecting rod. The height adjustment part includes a threaded rod and a guide rail. The threaded rod is rotatably installed on the back of the positioning plate through a bearing seat. The outer surface of the threaded rod is threaded with a connecting rod. The side of the connecting rod is slidably connected to the guide rail through a groove. The guide rail is fixedly installed on the back of the positioning plate.

[0013] Preferably, the third slide includes a replacement part, the replacement part includes a mounting base and bolts, the mounting base is fixedly mounted on the surface of the third slide, a correction block is movably mounted inside the mounting base, and the correction block and the mounting base are threadedly connected by bolts through threaded holes.

[0014] Preferably, the vertical planes of two adjacent connecting rods are staggered, and one side of the correction block is provided with an inclined surface, which matches the inclined surface of the end of the door frame.

[0015] Preferably, the auxiliary support assembly includes a support platform and a connecting seat. The connecting seat is installed at the center of the bottom of the frame. Two support plates are symmetrically and movably installed at the center of the interior of the connecting seat via a driving component. Both ends of the support plates are slidably connected to the frame. Two push rods are symmetrically and rotatably installed at the center of the upper surface of each support plate via a connecting shaft. The other end of each push rod is rotatably installed at the bottom of the support platform via a connecting shaft.

[0016] Preferably, the support platform includes rollers, and a plurality of rollers are rotatably mounted on the upper surface of the support platform through grooves at equal intervals. A driving component is installed at the end of each roller, and the driving component can drive the roller to rotate within the groove. When the roller rotates, it can convey the welded door leaf.

[0017] Preferably, the welding mechanism includes movable seats and mounting brackets. Two movable seats are symmetrically and movably mounted at the center of the top and bottom of the frame via a drive component. Each movable seat is equipped with a second cylinder, and the output ends of the two second cylinders are connected by the mounting bracket.

[0018] Preferably, the welding mechanism further includes a rotating component and a welding head. The rotating component includes a mounting frame and a rotating plate. The mounting plate is movably mounted inside the mounting frame via a driving component. The rotating plate is rotatably mounted on the bottom of the mounting plate via a driving component. The welding head is mounted on the side of the rotating plate via a driving component.

[0019] Compared with the prior art, the beneficial effects of the present invention are: a seamless welding device for door leaf production;

[0020] 1. The frame is equipped with two welding mechanisms at the top and bottom. The welding mechanism at the top can weld the upper part of the door leaf. After the upper part of the door leaf is welded, the support platform separates from the bottom of the door leaf. At this time, the welding mechanism at the bottom of the frame can weld the bottom of the door leaf with the help of the support seat. This makes it convenient to weld the upper and lower parts of the door leaf without flipping it over, which greatly improves welding efficiency and safety.

[0021] 2. When welding the bottom of the door leaf, the welding head will encounter the support seat supporting the door leaf during welding. The support seat can move through the cooperation of the parts. After the support seat moves, the welding mechanism can weld at that position. After the welding at that position is completed, the support seat will reset through the cooperation of the parts, so that the bottom of the door leaf can be completely welded. This makes it convenient for the support seat to make timely repositioning during the welding of the bottom of the door leaf, so that the welding of the bottom of the door leaf is more complete.

[0022] 3. When the door frame is placed on the two support bases, the motor inside the connecting rod on each support base works. When the motor works, it can drive the lead screw to rotate inside the connecting rod. When the lead screw rotates, it will drive the third slide to slide threadedly inside the connecting rod. When the third slide slides threadedly, it will drive the correction block to move. Since the two correction blocks are set in opposite directions, they will move towards each other or in opposite directions when they move. When the two correction blocks move towards each other, they can straighten the position of the door frame. After the door frame is straightened, the correction blocks will move away from the two ends of the door frame through the cooperation of the parts, which makes it convenient for the door frame to be corrected after placement and can improve the welding accuracy.

[0023] 4. After the door panel welding machine finishes, the motor can drive one of the toothed pulleys to rotate. When one toothed pulley rotates, it will drive the toothed belt to rotate. When the toothed belt rotates, it will drive the other toothed pulleys to rotate. When the toothed pulleys rotate, they will drive the roller to rotate in the groove. When the roller rotates, it will convey the door panel, improving the welding efficiency of the door panel.

[0024] 5. The welding head can adjust the welding angle through the cooperation of the mounting plate, rotating plate and motor, which makes it convenient for the welding head to weld various parts of the door leaf, improving the welding accuracy and welding range of the door leaf.

[0043] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort should fall within the scope of protection of the present application.

[0044] Furthermore, the terms "installation," "setup," "equipped with," "connection," "linking," and "socketing" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral structure; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium, or an internal connection between two devices, components, or parts. Those skilled in the art can understand the specific meaning of these terms in this application based on the specific circumstances.

[0045] Please see Figures 1-5 The present invention provides an embodiment of a seamless welding device for door leaf production, comprising: a frame 100, wherein a support mechanism 200 for supporting the door leaf is installed inside the frame 100, the support mechanism 200 includes a main support component 210 for supporting the bottom edge of the door leaf and an auxiliary support component 220 for supporting the center of the bottom of the door leaf, and welding mechanisms 300 are installed at the top and bottom of the frame 100, and the welding mechanisms 300 at the top and bottom can weld the upper part and the bottom of the door leaf respectively through the cooperation of the support mechanism 200; the main support component 210 includes a movable structure 211 and a support base 212.

[0046] It should be noted that when the frame and door panel of the door leaf are placed on the support base 212 of the main support component 210, the auxiliary support component 220 can provide auxiliary support for the bottom of the door leaf while the frame and door panel are being placed. The frame and door panel are aligned and assembled by the moving structure 211 and the correction structure 214. After the frame and door panel are assembled, the welding mechanism 300 at the top of the frame 100 can weld the upper part of the door leaf. After the upper part of the door leaf is welded, the auxiliary support component 220 can separate from the bottom of the door leaf. At this time, the welding mechanism 300 at the bottom of the frame 100 can weld the bottom of the door leaf. After the door leaf is welded, the auxiliary support component 220 can move the door leaf out of the interior of the frame 100.

[0047] like Figures 1-5As shown, the movable structure 211 includes a slide groove 2111 and a sliding frame 2115. Two slide grooves 2111 are symmetrically opened on each inner side of the frame 100. A first slide seat 2112 for driving the support seat 212 to move laterally is movably installed inside the slide groove 2111 through a driving component. When the support seat 212 moves horizontally along the opening of the slide groove 2111, it can make way for the welding position of the welding mechanism 300. A movable seat 2113 is installed on the surface of the first slide seat 2112. A second slide seat 2114 for driving the support seat 212 to move vertically is installed inside the movable seat 2113 through a driving component. A sliding frame 2115 is installed on the surface of the second slide seat 2114. The support seat 212 is movably installed on the outer surface of the sliding frame 2115. The support seat 212 and the sliding frame 2115 are connected by a driving component. When the support seat 212 moves horizontally along the surface of the sliding frame 2115, it can assemble the door leaf. The driving component is generally composed of components such as a motor and a lead screw.

[0048] It is conceivable that when the welding mechanism 300 at the bottom of the frame 100 is welding the bottom of the door leaf, the welding head 350 will encounter the support seat 212 supporting the door leaf during welding. At this time, the motor can drive the lead screw to rotate inside the slide groove 2111. When the lead screw rotates, it will drive the first slide seat 2112 to slide horizontally inside the slide groove 2111. When the first slide seat 2112 slides, it will drive the moving seat 2113 to move horizontally against the inner side of the frame 100. When the moving seat 2113 moves, it can drive the support seat 212 to move horizontally against the bottom of the door leaf towards the welded position through the sliding frame 2115. After the support seat 212 has moved, the welding mechanism 300 can weld at this position. After the welding at this position is completed, the support seat 212 will be reset through the cooperation of the parts, so that the bottom of the door leaf can be completely welded.

[0049] After the door leaf is welded, the motor can drive the lead screw to rotate inside the moving seat 2113. When the lead screw rotates, it will drive the second slide 2114 to slide threadedly inside the moving seat 2113. When the second slide 2114 slides threadedly, it can drive the support seat 212 to move vertically through the sliding frame 2115. When the support seat 212 moves vertically, it will push the door leaf out of the frame 100.

[0050] When the door frame needs to be assembled, it can be placed on the support 212 and the position of the door frame can be corrected by the correction structure 214. After the door frame is corrected, the motor can drive the lead screw to rotate inside the sliding frame 2115. When the lead screw rotates, it will drive the support 212 to slide on the outer surface of the sliding frame 2115. When the support 212 slides, the door frame can be moved to the designated position for assembly.

[0051] like Figures 2-5As shown, the main support assembly 210 also includes a correction structure 214, which includes a connecting rod 2141 and a correction block 2143. Each of the two support seats 212 has a connecting rod 2141 in opposite directions on its upper part. A third slide 2142 is movably installed inside the connecting rod 2141 through a driving component. The third slide 2142 is provided with a correction block 2143. The two correction blocks 2143 can move towards each other to correct and straighten the two ends of the door frame.

[0052] It is worth noting that when the door frame is placed on the two support seats 212, the motor inside the connecting rod 2141 on each support seat 212 works. When the motor works, it can drive the lead screw to rotate inside the connecting rod 2141. When the lead screw rotates, it will drive the third slide 2142 to slide threadedly inside the connecting rod 2141. When the third slide 2142 slides threadedly, it will drive the correction block 2143 to move. Since the two correction blocks 2143 are set in opposite directions, they will move towards each other or in opposite directions when they move. When the two correction blocks 2143 move towards each other, they can straighten the position of the door frame. After the door frame is straightened, the correction blocks 2143 will move away from both ends of the door frame through the cooperation of the parts.

[0053] like Figures 2-5 As shown, the main support assembly 210 also includes a positioning assembly 213. The positioning assembly 213 includes a first cylinder 2131 and a positioning plate 2132. The first cylinder 2131 is fixedly installed on the support base 212. The positioning plate 2132 is installed at the output end of the first cylinder 2131 through an elastic element. The elastic element is generally composed of components such as a compression groove and a spring. The bottom of the positioning plate 2132 is movably installed on the upper surface of the support base 212. When the first cylinder 2131 works, it can push the positioning plate 2132 to move horizontally along the upper surface of the support base 212. When the positioning plate 2132 moves horizontally, it can position the side of the door frame.

[0054] It is clear that before the door frame is corrected, the first cylinder 2131 will work. When the first cylinder 2131 works, it will push the positioning plate 2132 to move. When the positioning plate 2132 moves, its bottom will slide horizontally against the surface of the support base 212. The sliding of the positioning plate 2132 will drive the correction structure 214 on the back to move. When the positioning plate 2132 contacts one side of the door frame, the correction structure 214 will work to straighten the door frame. After the door frame is straightened, it will abut against the surface of the positioning plate 2132. After the support base 212 is assembled with the door frame, the output end of the first cylinder 2131 will slide inside the extrusion groove. When the output end of the first cylinder 2131 slides, it will compress the spring. When the spring is compressed, the spring force will act on the positioning plate 2132. The positioning plate 2132 will then compress the door frame to prevent the door frame from shaking during welding and affecting the welding accuracy.

[0055] like Figure 4 and Figure 5 As shown, a height adjustment part is installed at one end of the connecting rod 2141. The height adjustment part includes a threaded rod 21411 and a guide rail 21412. The threaded rod 21411 is rotatably installed on the back of the positioning plate 2132 through a bearing seat. The connecting rod 2141 is threadedly connected to the outer surface of the threaded rod 21411. The side of the connecting rod 2141 is slidably connected to the guide rail 21412 through a groove. The guide rail 21412 is fixedly installed on the back of the positioning plate 2132.

[0056] It should be understood that by rotating the end of the threaded rod 21411, its outer surface can rotate inside the bearing seat, and the end of the threaded rod 21411 will rotate inside the positioning plate 2132. When the threaded rod 21411 rotates, it will drive the connecting rod 2141 to slide threadedly. When the connecting rod 2141 slides threadedly, its surface can slide with the guide rail 21412 through the groove. When the connecting rod 2141 slides, it can drive the correction block 2143 to move vertically, so that the correction block 2143 can be adjusted in position according to the size of the door frame.

[0057] like Figure 4 and Figure 5 As shown, the third slide 2142 includes a replacement part, which includes a mounting base 21421 and a bolt 21422. The mounting base 21421 is fixedly mounted on the surface of the third slide 2142. A correction block 2143 is movably mounted inside the mounting base 21421. The correction block 2143 and the mounting base 21421 are threadedly connected by a bolt 21422 through a threaded hole.

[0058] It should be noted that when the shape of the end of the door frame changes, the bolt 21422 needs to be rotated so that it can slide through the threaded hole with the third slide block 2142 and the straightening block 2143. When the bolt 21422 slides out of the threaded hole, it can pull the straightening block 2143. When the straightening block 2143 is pulled, it will slide out of the groove of the third slide block 2142. The straightening block 2143 can be replaced according to the size of the door frame after disassembly.

[0059] like Figure 4 and Figure 5 As shown, the vertical surfaces of two adjacent connecting rods 2141 are staggered, and one side of the correction block 2143 is provided with an inclined surface, which matches the inclined surface of the end of the door frame.

[0060] It is conceivable that the third slide block 2142 will drive the connecting rod 2141 to move when assembling the door frame. When two adjacent connecting rods 2141 move, they will meet. Since the two connecting rods 2141 are not at the same height and are not on the same horizontal plane, the collision of the two adjacent connecting rods 2141 can be avoided.

[0061] When the correction block 2143 moves on the surface of the connecting rod 2141, it will move towards the third slide block 2142. When the correction block 2143 moves, it can press the inclined surface of the end of the door frame through its own inclined surface. Since the inclined surface of the correction block 2143 matches the inclined surface of the end of the door frame, the door frame can be straightened when the inclined surface of the correction block 2143 is in contact with the inclined surface of the end of the door frame.

[0062] like Figures 1-3 , Figure 6 As shown, the auxiliary support assembly 220 includes a support platform 221 and a connecting seat 224. The connecting seat 224 is installed at the center of the bottom of the frame 100. Two support plates 223 are symmetrically and movably installed at the center of the interior of the connecting seat 224 via a driving component. The driving component is generally composed of a motor, a reciprocating lead screw, and two internal threaded sliders. Both ends of the support plates 223 are slidably connected to the frame 100. Two push rods 222 are symmetrically and rotatably installed at the center of the upper surface of each support plate 223 via a connecting shaft. The other end of each push rod 222 is rotatably installed at the bottom of the support platform 221 via a connecting shaft.

[0063] It is worth noting that when the motor is working, it drives the reciprocating screw to rotate inside the connecting seat 224. When the reciprocating screw rotates, it drives the two internal threaded sliders inside the connecting seat 224 to move in opposite directions or in the opposite direction. When the two internal threaded sliders move in opposite directions or in the opposite direction, they drive the two support plates 223 to move in opposite directions or in the opposite direction. When the support plates 223 move, their two ends slide on the frame 100. When the support plates 223 move in opposite directions, they push the push rod 222 to move through the connecting shaft. When the push rod 222 moves, it can rotate through the connecting shaft. When the push rod 222 rotates, it can push the support platform 221 to move vertically through the connecting shaft at the other end. When the top of the support platform 221 moves to be flush with the upper surface of the support seat 212, it can provide auxiliary support for the bottom center of the door leaf. When the bottom welding mechanism 300 is welding the door leaf, the support platform 221 will descend to avoid the welding mechanism 300.

[0064] like Figure 6 As shown, the support platform 221 includes rollers 2211. Several rollers 2211 are rotatably mounted on the upper surface of the support platform 221 through grooves at equal intervals. A driving component is installed at the end of the rollers 2211. The driving component is generally composed of a motor, several toothed pulleys and toothed belts, etc. The operation of the driving component can drive the rollers 2211 to rotate in the grooves. When the rollers 2211 rotate, they can convey the welded door leaf.

[0065] It is clear that when the door panel welding machine is completed, the motor can drive one of the toothed pulleys to rotate. When one toothed pulley rotates, it will drive the toothed belt to rotate. When the toothed belt rotates, it will drive the other toothed pulleys to rotate. When the toothed pulleys rotate, they will drive the roller 2211 to rotate in the groove. When the roller 2211 rotates, it will convey the door panel.

[0066] like Figures 1-3 As shown in Figure 7, the welding mechanism 300 includes a movable seat 310 and a mounting frame 330. Two movable seats 310 are symmetrically and movably mounted at the center of the top and bottom of the frame 100 via a drive component. The drive component is generally composed of components such as a bearing housing, a lead screw, a pulley, a belt, and a motor. A second cylinder 320 is mounted on each movable seat 310, and the output ends of the two second cylinders 320 are connected through the mounting frame 330.

[0067] It should be understood that when the motor is working, it can drive the pulley to rotate. When the pulley rotates, it drives the belt to rotate. When the belt rotates, it drives another pulley to rotate. When the other pulley rotates, it drives the lead screw to rotate. When the lead screw rotates, it drives the movable seat 310 to slide horizontally left and right against the frame 100. When the movable seat 310 slides, it drives the second cylinder 320 to move. When the second cylinder 320 moves, it drives the mounting frame 330 to move. When the mounting frame 330 moves, it can move through the mounting plate 341, the rotating plate 342 and the welding head 350. When the welding head 350 moves, it can weld the door leaf in the left and right directions.

[0068] Furthermore, the operation of the second cylinder 320 can drive the mounting bracket 330 to move vertically. When the mounting bracket 330 moves vertically, it will drive the mounting plate 341, the rotating plate 342 and the welding head 350 to move vertically. When the welding head 350 moves vertically, it can weld at different positions on the vertical surface of the door leaf.

[0069] like Figures 1-3 , Figure 7 As shown, the welding mechanism 300 also includes a rotating component and a welding head 350. The rotating component includes a mounting frame 330 and a rotating plate 342. The mounting plate 341 is movably mounted inside the mounting frame 330 via a driving component. The driving component is generally composed of components such as a motor, a lead screw, and an internal threaded slider. The rotating plate 342 is rotatably mounted on the bottom of the mounting plate 341 via a driving component. The welding head 350 is mounted on the side of the rotating plate 342 via a driving component. The driving components on both the mounting plate 341 and the rotating plate 342 are motors.

[0070] It should be noted that when the motor is working, it can drive the lead screw to rotate inside the mounting bracket 330. When the lead screw rotates, it will drive the internal thread slider to slide horizontally inside the mounting bracket 330. When the internal thread slider slides, it can drive the mounting plate 341 to move back and forth against the surface of the mounting bracket 330. When the mounting plate 341 moves, it can drive the welding head 350 to move back and forth through the rotating plate 342. When the welding head 350 moves, it can weld the door leaf in the front and back directions.

[0071] Furthermore, the welding head 350 can adjust the welding angle through the cooperation of the mounting plate 341, the rotating plate 342 and the motor, thereby improving the welding accuracy and welding range of the welding head 350.

[0072] The above are merely preferred embodiments of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
