Description

Technical Field

[0001] This invention relates to the field of laser welding technology, specifically to a laser welding device for processing hydraulic gates. Background Technology

[0002] Hydraulic gate frames, made of high-strength steel or alloys, support the entire structure; therefore, welding quality directly affects the gate's strength and lifespan. To improve load-bearing capacity, reinforcing plates are typically added to key locations on the gate frame. Traditional welding methods, such as manual welding, are prone to deformation and uneven welds, affecting structural strength. While automated welding equipment improves efficiency, it still has limitations in welding precision and heat control, making it difficult to meet high-precision welding requirements, especially when welding complex-shaped gate frames and reinforcing plates, where defects are easily introduced.

[0003] Chinese Patent Publication No. CN119282329A discloses an arc welding device for confined spaces of steel gates. The device mainly consists of a base, a transverse sliding base, a longitudinal sliding table, a lifting frame, four arc welding torches, an adjustment mechanism, and an electrical control system. It enables automated welding operations in confined spaces of steel gates, increasing efficiency by two to four times compared to manual welding. Furthermore, the entire welding process only requires the operator to stand in front of the CNC terminal, avoiding safety issues such as head congestion, dizziness, falls due to imbalance, welding fume inhalation, and eye irritation during actual welding operations. This improves the efficiency, safety, and stability of welding operations in confined spaces of steel gates. However, the following drawbacks still exist in its implementation: The aforementioned patent documents achieved automation of the welding process during implementation, improving efficiency and safety.

[0018] The following description is intended to disclose the invention and enable those skilled in the art to implement it. The preferred embodiments described below are merely examples, and other obvious variations will occur to those skilled in the art.

[0019] Example 1 Please refer to Figures 1-11 As shown, a laser welding device for processing hydraulic gates includes a body 1. A table 103 is fixedly installed at the top center of the body 1. A first conveying mechanism 2 is provided on the top of the table 103. The first conveying mechanism 2 is used to convey the gate column A-1. A second conveying mechanism 3 is also provided on the first conveying mechanism 2 for conveying the crossbar A-2. Adjustment mechanisms 4 are provided on both sides of the top of the body 1. A feeding mechanism 5 and an auxiliary mechanism 6 are installed on the top of the adjustment mechanism 4. The adjustment mechanism 4 is used to adjust the distance between the two feeding mechanisms 5. The feeding mechanism 5 is used to feed the reinforcing piece A-3. A robotic arm 101 is connected to the front and rear symmetrical positions on the left side of the top of the body 1. The end of the robotic arm 101 holds a laser welding head 102.

[0020] Example 2 Please refer to Figure 2As shown, the first conveying mechanism 2 includes a first threaded rod 201 and a first fixed rod 202. The first threaded rod 201 is rotatably connected to the left side of the table body 103, and the first fixed rod 202 is fixedly connected to the left side of the table body 103. The threads at both ends of the first threaded rod 201 have opposite directions of rotation, and both ends of the outer wall of the first threaded rod 201 are threadedly connected to movable frames 204. Both sets of movable frames 204 are slidably connected to the first fixed rod 202. A first servo motor 203 is provided on the outer wall of the table body 103, and the outer end of the first threaded rod 201 is fixedly connected to the output end of the first servo motor 203.

[0021] Please refer to Figure 3 As shown, the first conveying mechanism 2 also includes a second fixed rod 206 welded inside the movable frame 204. Two sets of symmetrical L-shaped plates 208 are slidably connected to the second fixed rod 206. The two sets of L-shaped plates 208 are respectively threaded to both ends of the outer wall of the second threaded rod 205. The second threaded rod 205 is rotatably connected inside the movable frame 204, and the outer end of the second threaded rod 205 is fixedly connected to the output end of the second servo motor 207. The second servo motor 207 is located at the top of the movable frame 204. Several sets of first transport wheels 209 are rotatably connected to the inner side of the horizontal plate of the L-shaped plate 208.

[0022] Please refer to Figure 2 , Figure 4 and Figure 5 As shown, a first electric push rod 210 and a third electric push rod 214 are provided on the L-shaped plate 208 on the front and rear sides. The output ends of the first electric push rod 210 and the third electric push rod 214 are respectively fixedly mounted with a first mounting block 211 and a second mounting block 215. The outer walls of the first mounting block 211 and the second mounting block 215 are respectively fixedly connected with a second electric push rod 212 and a fourth electric push rod 216. The output ends of the second electric push rod 212 and the fourth electric push rod 216 are respectively fixedly connected with a first limiting plate 213 and a second limiting plate 217.

[0023] Those skilled in the art will understand that the output of the second servo motor 207 drives the second threaded rod 205 to rotate, causing the two sets of L-shaped plates 208 connected to the same second threaded rod 205 to move closer or further apart, thereby causing the several sets of first transport wheels 209 on the two sets of L-shaped plates 208 to move closer or further apart, changing the distance between the vertically symmetrical first transport wheels 209. This is suitable for transporting gate pillars A-1 of different thicknesses. During transport, it is worth noting that the inner side of the vertical plate of the L-shaped plate 208 is in contact with the bottom horizontal plate of the gate pillar A-1. Furthermore, through the cooperation of the output of the second electric push rod 212 and the output of the fourth electric push rod 216, the inner side of the first limiting plate 213 is in contact with the outer side of the vertical plate of the gate pillar A-1. In this way, the front and rear sides of the gate pillar A-1 are limited, thereby limiting the transport of the gate pillar A-1. During the transport process, it will not fall or deviate. Furthermore, the output end of the first servo motor 203 drives the first threaded rod 201 to rotate, causing the two sets of movable frames 204 to move closer or further apart, changing the distance between the front and rear L-shaped plates 208, and realizing the adjustment of the spacing of the front and rear conveying gate columns A-1 according to the width requirements of the gate frame.

[0024] Example 3 Please refer to Figure 6. The second conveying mechanism 3 includes a lifting frame 302. A fifth electric push rod 301 is fixedly installed on the two sets of L-shaped plates 208 on the front and rear sides. The lifting frame 302 is fixedly connected to the output end of the fifth electric push rod 301. Several sets of second transport wheels 303 are rotatably connected inside the lifting frame 302. A sixth electric push rod 304 is fixedly installed on the outer wall of the first limiting plate 213. The output end of the sixth electric push rod 304 is fixedly connected to the third limiting plate 305.

[0025] Those skilled in the art will understand that when the first transport wheel 209 on the two sets of L-shaped plates 208 on the front and rear sides limits the transport of the gate column A-1, the output ends of the fifth electric push rod 301 on the two sets of L-shaped plates 208 symmetrically extended or retracted synchronously, thereby changing the distance between the two sets of second transport wheels 303 symmetrically arranged. The crossbar A-2 is placed longitudinally, with its front and rear ends located between the two sets of second transport wheels 303 symmetrically arranged on the front and rear sides, respectively, to transport the crossbar A-2. Since the vertical plate of the gate column A-1 has a certain thickness, in order to allow the crossbar A-2 to accurately enter the interior of the gate column A-1, the present invention can control the output ends of the two sets of sixth electric push rods 304 on the front and rear sides to extend or retract, thereby allowing the inner sides of the two sets of third limiting plates 305 to fit against the front and rear ends of the crossbar A-2, thus also realizing the limiting transport of the crossbar A-2.

[0026] Example 4 Please refer to Figure 8. The adjustment mechanism 4 includes two sets of support plates 401 fixedly connected to the front and rear sides of the top of the body 1. A third threaded rod 402 is rotatably connected between the two sets of support plates 401. The threads at both ends of the third threaded rod 402 have opposite directions, and both ends of the outer wall of the third threaded rod 402 are threadedly connected to movable tables 405. Both sets of movable tables 405 are slidably connected to a third fixed rod 403. The two ends of the third fixed rod 403 are welded to the inner sides of the two sets of support plates 401 respectively. A third servo motor 404 is provided on the outer wall of one set of support plates 401, and the outer end of the third threaded rod 402 is fixedly connected to the output end of the third servo motor 404.

[0027] Those skilled in the art will understand that by driving the third threaded rod 402 to rotate through the output end of the third servo motor 404, the two sets of movable tables 405 on the front and rear sides move closer or further apart, thereby driving the feeding mechanisms 5 on both sides to move closer or further apart. It is worth noting that, in this invention, the top plate of the movable platform 405 is higher than the top height of the table body 103.

[0028] Example 5 Please refer to Figure 9. The feeding mechanism 5 includes a frame 501 fixedly installed on the top of the movable table 405. The frame 501 is provided with a transverse groove 502 and a longitudinal groove 503 that are interconnected. A push plate 504 is slidably connected in the transverse groove 502. A first sliding rod 505 is fixedly connected to the right side of the push plate 504. The other end of the first sliding rod 505 extends to the outside of the frame 501 and is fixedly connected to the connecting plate 506. Two sets of springs 507 are installed between the connecting plate 506 and the frame 501.

[0029] Please refer to Figure 9. An L-shaped part 512 is slidably connected inside the longitudinal groove 503. A drive motor 508 is provided at the bottom of the movable table 405. The output end of the drive motor 508 is fixedly connected to the rotating arm 509. A slider is provided at the top of the rotating arm 509. The slider is slidably connected inside the frame 510. A second sliding rod 511 is also slidably connected inside the frame 501. One end of the second sliding rod 511 is fixedly connected to the short plate of the L-shaped part 512, and the other end of the second sliding rod 511 is fixedly connected to the outer wall of the frame 510.

[0030] Those skilled in the art will understand that initially, several sets of reinforcing plates A-3 are placed inside the transverse groove 502. The leftmost reinforcing plate A-3 is also located inside the longitudinal groove 503. The left side wall of the leftmost reinforcing plate A-3 is in contact with the right side wall of the fifth limiting plate 516. The output end of the drive motor 508 drives the rotating arm 509 to rotate, causing the end slider of the rotating arm 509 to slide inside the frame 510, driving the L-shaped part 512 to move towards the table body 103, pushing the reinforcing plate A-3 backward. Two sets of springs 507 pull the connecting plate 506, causing the push plate 504 to move towards the longitudinal groove 503. The push plate 504 pushes the new reinforcing plate A-3 into the longitudinal groove 503, and the left side wall of the new reinforcing plate A-3 is then in contact with the right side wall of the fifth limiting plate 516, and so on.

[0031] Please refer to Figure 9. The transverse groove 502 has a fourth limiting plate 514 on both sides inside. The frame 501 has a seventh electric push rod 513 on both the front and rear sides. The outer sides of the two sets of fourth limiting plates 514 are respectively fixedly connected to the output ends of the two sets of seventh electric push rods 513. The frame 501 also has an eighth electric push rod 515 on the left side. The output end of the eighth electric push rod 515 extends into the interior of the longitudinal groove 503 and is fixedly connected to the fifth limiting plate 516.

[0032] Those skilled in the art will understand that by controlling the extension or retraction of the output ends of the seventh electric push rods 513 on both sides, the fourth limiting plates 514 on both sides are brought closer or further apart, changing the distance between the fourth limiting plates 514 on both sides. This is suitable for placing reinforcing pieces A-3 of different widths inside the transverse groove 502 and limiting them. Furthermore, by controlling the extension or retraction of the output end of the eighth electric push rod 515, the fifth limiting plate 516 is moved to the right or left, changing the distance between the right side wall of the fifth limiting plate 516 and the inner right side of the longitudinal groove 503. Thus, the L-shaped piece 512 in this invention is also suitable for pushing reinforcing pieces A-3 of different lengths to the rear.

[0033] Example 6 Please refer to Figure 10. The auxiliary mechanism 6 includes two sets of fixed plates 601 fixedly installed on the top of the movable platform 405. A lead screw 602 is rotatably connected between the two sets of fixed plates 601. A movable plate 605 is threadedly connected to the outer wall of the lead screw 602. The movable plate 605 is slidably connected to the guide rod 603. The guide rod 603 is fixedly installed between the two sets of fixed plates 601. A ninth electric push rod 606 is provided on the top of the movable plate 605. The output end of the ninth electric push rod 606 passes through the top wall of the movable plate 605 and is fixedly installed with a pulling block 607. A stepper motor 604 for driving the lead screw 602 to rotate is provided on the outer wall of one set of fixed plates 601.

[0034] Those skilled in the art will understand that the output end of the stepper motor 604 drives the lead screw 602 to rotate, causing the moving plate 605 to move horizontally back and forth along the outer wall of the guide rod 603, thereby driving the pulling block 607 to move horizontally back and forth; and by controlling the output end of the ninth electric push rod 606 to extend or retract, the pulling block 607 is driven to move downward or upward.

[0035] To clearly describe the working principle of this invention, we will use... Figure 1 This is explained from a directional perspective, which refers to the "up, down, left, right, front, and back" as mentioned below, specifically as follows: S1. The output of the second servo motor 207 drives the second threaded rod 205 to rotate, causing the two sets of L-shaped plates 208 connected to the same second threaded rod 205 to move closer or further apart. This, in turn, causes the several sets of first transport wheels 209 on the two sets of L-shaped plates 208 to move closer or further apart, changing the distance between the vertically symmetrical first transport wheels 209. This distance is adapted to the height of the gate column A-1 to be transported. The mechanical gripper on the outside of the right side of the machine body 1 then moves the gate columns one by one. Column A-1 is placed simultaneously between the first transport wheels 209 on both sides, which are symmetrically arranged vertically. During placement, the inner side of the vertical plate of the L-shaped plate 208 is in contact with the bottom horizontal plate of the gate column A-1. Through the combined action of the output end of the second electric push rod 212 and the output end of the fourth electric push rod 216, the inner side of the first limiting plate 213 is in contact with the outer side of the vertical plate of the transported gate column A-1, thereby limiting the front and rear sides of the gate column A-1 and thus limiting the transport of the gate column A-1. Then, the output end of the first servo motor 203 drives the first threaded rod 201 to rotate, causing the two sets of movable frames 204 to move closer or further apart, changing the distance between the front and rear L-shaped plates 208, and realizing the adjustment of the spacing of the front and rear conveying gate columns A-1 according to the width requirements of the gate frame. S2. By controlling the output ends of the fifth electric push rods 301 on the two sets of L-shaped plates 208 symmetrically arranged on both sides to extend or retract synchronously, the distance between the second transport wheels 303 symmetrically arranged on both sides is changed. The mechanical gripper on the right side of the machine body 1 places each crossbar A-2 between the second transport wheels 303 symmetrically arranged on the front and rear sides. The crossbar A-2 is placed longitudinally. Then, by controlling the output ends of the two sets of sixth electric push rods 304 on the front and rear sides to extend or retract, the inner sides of the two sets of third limiting plates 305 are respectively attached to the front and rear ends of the crossbar A-2, which also realizes the limiting and conveying of the crossbar A-2. S3. When the gate pillars A-1 on the front and rear sides reach the longitudinal grooves 503 in the front and rear side frames 501 respectively, the first symmetrical transport wheel 209 stops transporting the gate pillars A-1. Under the action of the output end of the second servo motor 207, the first symmetrical transport wheel 209 clamps the gate pillars A-1 again. Simultaneously, the output end of the fifth electric push rod 301 is controlled to retract slightly, so that the second symmetrical transport wheel 303 continues to transport the crossbar A-2. The crossbar A-2 is accurately transported to the left side of the gate pillars A-1 on both sides, and then the transport stops. The second symmetrical transport wheels 303 also move closer to each other to clamp the crossbar A-2. The left side of the crossbar A-2 is aligned with the left end of the two sets of gate pillars A-1. The robotic arms 101 on both sides drive the laser welding heads 102 to weld the joints of the two sets of gate pillars A-1 and crossbar A-2 respectively. S4. At this time, by controlling the output terminals of the drive motors 508 on both sides, the rotating arms 509 on both sides are driven to rotate, so that the L-shaped parts 512 on both sides move towards the table body 103, and the reinforcing plates A-3 on both sides move towards the two sets of gate columns A-1, so that the reinforcing plates A-3 on both sides are attached to the outer walls of the two sets of gate columns A-1, and the robotic arms 101 on both sides drive the laser welding heads 102 to perform laser welding on the attachment points of the reinforcing plates A-3 and the gate columns A-1. The first transport wheel 209 continues to transport the two sets of gate columns A-1 and a set of crossbars A-2 as a whole, so that the other parts on the two sets of gate columns A-1 reach the longitudinal groove 503 position in the frame 501. The other reinforcing pieces A-3 are pushed to the outer wall of the gate column A-1 by the L-shaped piece 512, and the welding is repeated. This process is repeated until the outer wall of the two sets of gate columns A-1 is covered with reinforcing pieces A-3. When the first transport wheel 209 transports the right ends of the two sets of gate pillars A-1 to the longitudinal groove 503 position in the frame 501, the second transport wheel 303 continues to transport the other crossbar A-2, so that the other crossbar A-2 is also transported to the inner right end of the two sets of gate pillars A-1, and the right side of the crossbar A-2 is aligned with the right end of the two sets of gate pillars A-1. The second transport wheel 303 stops transporting it and clamps it. The above operation is repeated, and the laser welding head 102 welds the joint between the two sets of gate pillars A-1 and the crossbar A-2 again, thereby forming the gate frame body. Figure 11 As shown; Subsequently, the first transport wheel 209 continues to transport the formed gate frame body to the conveyor on the left side of the machine body 1, and then to the next process. Throughout the process, the gate column A-1, crossbar A-2 and reinforcing plate A-3 are automatically fed and automatically welded. It is also applicable to the production of gate frames of different sizes, which improves the applicability of the invention. The invention has substantial improvements and is conducive to its widespread use.

[0036] Furthermore, it is worth mentioning that, since the output end of the first servo motor 203 can drive the first threaded rod 201 to rotate, the spacing between the front and rear gate columns A-1 can be adjusted according to the width requirements of the gate frame. Therefore, if the gate column A-1 being transported is far from the frame 501, the L-shaped piece 512 cannot push the reinforcing piece A-3 onto the outer wall of the gate column A-1. Therefore, the present invention provides an adjustment mechanism 4, the top plate of the movable platform 405 is higher than the top height of the table body 103, and the output end of the third servo motor 404 drives the third threaded rod 402 to rotate, so that the two sets of movable platforms 405 on the front and rear sides move closer to each other, and so that the frames 501 on both sides move closer to the gate columns A-1 on both sides, thus further improving the ingenuity of the design of the present invention. Furthermore, once the reinforcing plate A-3 inside the transverse groove 502 on the frame 501 is used up, the push plate 504 is located on the left side inside the transverse groove 502. Through the action of the auxiliary mechanism 6, the pull block 607 automatically pulls the push plate 504 to the right side inside the transverse groove 502. The robotic arm 101 lowers the laser welding head 102 and transfers the external reinforcing plate A-3 into the transverse groove 502, thus realizing the automated supply of the reinforcing plate A-3, which is convenient and fast.
