Description

Technical Field

[0001] The present invention relates to the technical field of processing pressure-resistant top plates of ovens, and in particular to a production device and a production process of a high-strength pressure-resistant top plate of an oven. Background Art

[0002] In the film stretching production line, the oven is one of the core equipment to ensure film production quality. The oven top, serving as a work platform for maintenance personnel, requires a high load-bearing capacity to ensure personnel safety and proper equipment maintenance. Therefore, the pressure-resistant top plate used on the oven top is not an ordinary flat plate. Instead, it adopts a hollow reinforced frame plate with a supporting reinforcement structure. Multiple supporting steel parts are welded at equal intervals on both sides to form a stable mechanical support system that meets high-strength load-bearing requirements. At present, in the production and processing of the pressure-resistant roof, the welding process faces many technical bottlenecks. The existing welding equipment generally has the limitation of single welding, and can only weld one side of the roof, and cannot achieve double-sided simultaneous welding. This results in the need to complete the welding process of the entire roof after welding one side, and then perform a tedious flipping operation on the roof to weld the other side. This process not only increases the complexity of the operation process and prolongs the overall production cycle, but also in the frequent flipping process, there is a risk of deformation of the roof due to uneven force, which affects the dimensional accuracy and structural strength of the roof. In addition, existing welding methods mostly rely on manual welding of supporting steel parts one by one, with a low degree of automation. Manual operation is not only inefficient and difficult to meet the needs of large-scale production, but also the welding quality is greatly affected by the operator's skill level and working status. Problems such as unstable welding parameters and uneven weld quality are prone to occur, resulting in poor product consistency and increased quality inspection and rework costs. At the same time, manual welding also brings higher labor costs. At a time when labor resources are becoming increasingly tight, it has become an important factor restricting the improvement of corporate production efficiency. Summary of the Invention

[0013] A production process for a high-strength, pressure-resistant top plate of an oven comprises the following steps: The steps include: Step 1: According to the actual size of the top plate to be welded, manually adjust the movable block to slide in the support rail, change the sliding displacement of the clamping seat on the movable block, and flexibly adjust the distance between the upper and lower clamping seats. After completing the distance adjustment, insert the locking screw on the fixing piece into the corresponding limit hole, fix the clamping plate, and complete the preliminary positioning and clamping of the top plate to be welded; Step 2: Prepare the top plate to be welded and the supporting steel parts, place the top plate to be welded horizontally between the guide rollers of the clamping mechanism, ensure that the top plate to be welded is in the middle of the welding table, start the first motor, and the output end of the first motor drives the worm to rotate. The worm and the worm gear are engaged and driven to make the first screws in the side rails on both sides rotate synchronously. The threads at both ends of the first screw rotate in opposite directions, driving the sliders and clamping parts at both ends to move toward each other along the side rails and the slide groove until the guide rollers on the inner side of the clamping seat and the clamping plate are tightly fitted on both sides of the top and bottom of the top plate to be welded; Step 3: After checking that the clamping state of the top plate to be welded is correct, start the second motor of the drive group. The second motor drives the guide rollers on the clamping plate and the clamping seat to rotate through the synchronous wheel and the synchronous belt. The L-shaped guide roller combination is used to make the top plate to be welded move smoothly inside the guide roller. According to the welding requirements, the top plate to be welded is adjusted to the appropriate welding starting position; Step 4: Start the third motors of the welding mechanisms on both sides. The third motor drives the rotating shaft to rotate, driving the first electric push rod to rotate the upper clamping group and welding group around the top plate to be welded, and move the clamping group to the outer working position to prepare for placing the supporting steel parts to be welded; Step 5: Place the supporting steel piece to be welded accurately at the designated position between the inner sides of the two second electric push rods, start the second electric push rod, and the second electric push rod pushes the inner clamping plate inward to clamp and fix the supporting steel piece to be welded, ensuring that the supporting steel piece remains stable during the welding process; Step 6: Start the third motor again to rotate the shaft, drive the first electric push rod to move the clamped supporting steel piece to be welded toward the top plate to be welded, then start the first electric push rod to accurately control the supporting steel piece to fit to the preset welding positions on both sides of the top plate to be welded, and complete the alignment of the supporting steel piece and the top plate to be welded; Step 7: Start the fourth motor to drive the second screw in the vertical rail to rotate. The opposite thread rotation directions of the two ends of the second screw are used to make the sliding block drive the double-arm welding module to move up and down along the vertical rail. According to the welding process requirements, adjust the vertical displacement of the laser welding head to the appropriate height; Step 8: While the laser welding head is moving up and down, the fifth motor is started to drive the rotating wheel to rotate and adjust the welding angle of the laser welding head. After the angle is adjusted to the desired position, the third electric push rod is extended and retracted to move the laser welding head precisely to the welding position required for the connection between the supporting steel part and the top plate to be welded. Step 9: After confirming that the position and angle of the laser welding head are correct, start the welding process and perform high-precision linear motion welding on the connection between the supporting steel parts and the top plate to be welded to complete one welding operation; Step 10: After welding is completed, start the second motor to drive the synchronous wheel to rotate, drive the top plate to be welded to the next welding station, and at the same time start the third motor at the bottom of the round seat to turn the top clamping group and welding group to the outside. The operator places new supporting steel parts to be welded and repeats steps 5 to 9 for continuous welding until the welding production of the entire top plate to be welded is completed.

[0014] Beneficial effects of the present invention: 1. During the application of this device, the linkage design of the clamping mechanism can realize the automatic clamping and positioning of the top plate to be welded. During the specific application, the first motor drives the worm gear to link the first screw, so that the clamping piece moves synchronously, and cooperates with the L-shaped guide roller to closely fit the upper and lower sides of the top plate to be welded; the movable block and the locking screw design support flexible adjustment of the clamping seat spacing, which can quickly adapt to top plates of different sizes to be welded. The second motor of the drive group drives the guide roller to rotate through the synchronous wheel, automatically adjusts the welding position of the top plate to be welded, and reduces manual intervention. It can be seen that by setting a clamping mechanism consisting of a slide, a first motor, a side rail and an adjustable clamping piece, in conjunction with the L-shaped guide roller layout and the drive group, the clamping seat spacing can be flexibly adjusted and accurately fixed according to the size of the top plate to be welded during use. At the same time, the guide roller is driven by the motor to rotate, so as to achieve smooth movement of the top plate and precise adjustment of the welding position. This design can automatically adapt to top plates of different specifications, avoid manual positioning errors, thereby achieving the effect of improving positioning efficiency and accuracy, providing a stable foundation for subsequent welding, and enhancing the adaptability of the device to diversified production needs; 2. This device adopts the collaborative operation of welding mechanisms on both sides. After the top plate to be welded is clamped, the third motor drives the clamping group to rotate and pick up the material. The second electric push rod automatically clamps the supporting steel parts and fits the top plate to be welded. The fourth and fifth motors cooperate with the electric push rods to realize the multi-dimensional adjustment of the displacement and angle of the laser welding head, and accurately complete the welding. After welding, the top plate to be welded automatically shifts, and the welding group resets and cycles. The continuous process of centering clamping and double-sided welding avoids the flipping process of traditional single-sided welding and reduces waiting time. At the same time, its adjustable design can adapt to top plates to be welded of different sizes, and the design of flexible displacement of the top plate to be welded can perform fast, uninterrupted and continuous welding on both sides of the top plate to be welded, which greatly improves the welding efficiency and meets the needs of large-scale production. 3. During the application of this device, it adopts a bilaterally symmetrical welding mechanism to completely solve the limitations of single-sided welding. Synchronous operation avoids the risk of flipping and deformation of the top plate to be welded, integrates the double-sided welding process, and significantly improves production efficiency. At the same time, it can eliminate manual operation errors, ensure the stability of welding parameters, effectively improve product qualification rate, and reduce labor costs. The design of two sets of L-shaped guide rollers combined with the multi-dimensional welding module can reduce the movement resistance of the top plate to be welded, support welding at different positions and angles on both sides of the top plate to be welded, and enhance the versatility of the equipment; the automated process reduces material loss and rework, and double-sided processing can further improve its welding processing efficiency and quality.

DETAILED DESCRIPTION

[0017] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention. Example 1

[0018] A production device for a high-strength, pressure-resistant top plate of an oven comprises a welding platform 1, a clamping mechanism 2 is fixedly mounted on the top of the welding platform 1, and welding mechanisms 3 are fixedly mounted on the middle of both sides of the clamping mechanism 2; The clamping mechanism 2 includes a slide 21, a first motor 22 and a side rail 23. The slide 21 is opened in the middle of the welding table 1. The side rails 23 are fixedly installed at both ends of the welding table 1. The inner sides of the side rails 23 are connected to the inside of the slide 21. The inside of the side rails 23 is rotatably connected to the first screw rod 24. The threads at both ends of the first screw rod 24 rotate in opposite directions. The inside of the slide 21 is rotatably connected to the worm 25. The middle part of the first screw rod 24 is fixedly connected to the worm gear 26. The worm 25 and the worm gear 26 are transmission connected. The first motor 22 is fixedly installed in the middle of one side of the welding table 1. The output end of the first motor 22 and one end of the worm gear 25 are fixedly connected. Both ends of the first screw rod 24 are threadedly connected to a slider 27. A clamping member 28 is fixedly installed on the top of the slider 27. A driving group 29 is provided on a clamping member 28. The inner side of the clamping member 28 clamps the top plate 6 to be welded. When the device is used and working, the top plate 6 to be welded can be placed first. On the inner side of the clamping member 28 of the clamping mechanism 2, the first motor 22 is started, and its output end drives the worm 25 to rotate, and the worm 25 engages with the worm wheel 26 for transmission, so that the first screw rod 24 in the side rail 23 rotates synchronously. Since the threads at both ends of the first screw rod 24 rotate in opposite directions, the sliders 27 at both ends will drive the clamping member 28 to move toward or away from the side rail 23 and the slide groove 21, thereby realizing synchronous adjustment of the displacement of the clamping member 28, so that the inner side of the clamping member 28 can firmly clamp the top plate 6 to be welded. At the same time, the driving group 29 provided on one of the clamping members 28 can provide power for the subsequent movement of the top plate 6 to be welded after the top plate 6 to be welded is clamped, so as to adjust the top plate 6 to be welded to the appropriate position and cooperate with the welding mechanisms 3 on both sides to perform welding operations. The clamping mechanism 2 on the top of the welding table 1 cooperates with the welding mechanisms 3 on both sides to form a complete production device working system, which can realize fast and efficient two-sided welding processing.

[0019] Combine Figure 1-Figure 3 and Figure 6-Figure 7 As shown, the clamping member 28 includes a receiving plate 281, both ends of the outer side of the receiving plate 281 are fixedly connected to the supporting rails 282, both ends of the inner side of the supporting rails 282 are slidably connected to the movable blocks 283, the inner side of the movable block 283 is fixedly connected to the clamping seat 284, the inner side of the clamping seat 284 is fixedly connected to the clamping plate 285, the inner side of the receiving plate 281 is also fixedly connected to the clamping seat 284, the inner side of the clamping plate 285 and the inner side of the clamping seat 284 are evenly spaced and rotatably connected to the guide rollers 286, and the clamping The guide rollers 286 on the holding plate 285 and the clamping seat 284 are arranged in an L shape, and fixing parts 287 are fixedly installed at both ends of the outer side of the top clamping seat 284. The fixing part 287 is threadedly connected with a locking screw 288. The end of the locking screw 288 passes through the fixing part 287. The top and bottom of the top plate 6 to be welded are respectively clamped between the inner sides of the guide rollers 286. The inner side of the supporting rail 282 is provided with limiting holes 289 at equal intervals, and the end of the locking screw 288 is inserted into the inside of the limiting hole 289.

[0020] In the technical solution of the embodiment of the present application, during the use of the clamping member 28, the first step is to adapt and adjust it according to the specific thickness parameters of the top plate 6 to be welded. The operator manually pushes the movable block 283 to slide along the track direction in the internal space of the supporting rail 282. As the movable block 283 slides, the position of the clamping seat 284 fixed to it also changes, thereby realizing flexible adjustment of the distance between the upper and lower clamping seats 284. When the distance is adjusted to the appropriate distance, the locking screw 288 on the fixing member 287 is screwed so that the end of the locking screw 288 passes through the fixing member 287 and is accurately inserted into the limiting holes 289 pre-opened at equal intervals on the inner side of the supporting rail 282. In this way, the clamping member 28 The position of the holder 284 is firmly fixed, and the setting of the spacing of the clamping parts 28 is completed. Then, the top plate 6 to be welded is placed on the inner side of the clamping part 28. At this time, the external driving structure linked to the clamping part 28 is started. The operation of this structure drives the receiving plate 281 to be displaced, and the receiving plate 281 then drives the clamping seat 284 and the clamping plate 285 connected to it to move together. During the movement, the guide rollers 286 with an L-shaped layout on the inner side of the clamping plate 285 and the clamping seat 284 gradually approach the top plate 6 to be welded until the top and bottom of the top plate 6 to be welded are tightly fitted and clamped by these guide rollers 286, thereby fixing the top plate 6 to be welded. The adjustable design of the clamping part 28 during its overall application can improve the adaptability of the device during overall use. Example 2

[0021] Combine Figures 1-6 and Figure 8 As shown, the drive group 29 includes a second motor 291, which is fixedly mounted at both ends of the top of a bottom supporting plate 281. The output end of the second motor 291 is fixedly connected to a synchronous wheel 292, and both sides of the top of the clamping plate 285 close to the second motor 291 are also rotatably connected to the synchronous wheels 292. The bottom of the synchronous wheel 292 on the clamping plate 285 is connected to the top of the guide roller 286 on the clamping plate 285, and the synchronous wheels 292 are connected through a synchronous belt 293.

[0022] The technical solution in the above-mentioned embodiment of the present application, during the use of the device, when the driving group 29 is working, the second motor 291 fixedly installed at the two ends of the top of the bottom supporting plate 281 is started, and the second motor 291 runs to output power, driving the synchronous wheel 292 fixedly connected to its output end to rotate, and the synchronous wheel 292 is connected to the synchronous wheel 292 rotatably connected on both sides of the top of the clamping plate 285 near the side of the second motor 291 through a synchronous belt 293. The transmission of the synchronous belt 293 causes the synchronous wheel 292 on the clamping plate 285 to rotate accordingly. Since the bottom of the synchronous wheel 292 on the clamping plate 285 is connected to the top of the guide roller 286 on the clamping plate 285, the rotation of the synchronous wheel 292 will transmit power to the guide roller 286, thereby driving the guide roller 286 to rotate. The friction force generated by the rotation of the guide roller 286 acts on the top plate 6 to be welded clamped inside it, pushing the top plate 6 to be welded to move smoothly inside the guide roller 286, thereby adjusting the welding position, so that the top plate 6 to be welded can be moved to the corresponding work station according to welding requirements.

[0023] Combine Figures 1-6 As shown, the welding mechanism 3 includes a round seat 31, which is fixedly installed in the middle of both sides of the welding table 1, and a third motor 32 is fixedly installed on the bottom of the round seat 31, and the output end of the third motor 32 passes through the round seat 31 and is fixedly installed with a rotating shaft 33, and the top of the rotating shaft 33 is fixedly installed with a first electric push rod 34, and the output end of the first electric push rod 34 is fixedly installed with a clamping group 35, and the middle part of the clamping group 35 is fixedly installed with a welding group 36, and the inner side of the clamping group 35 clamps the supporting steel part 37 to be welded, and the clamping group 35 includes a concave seat 351, which is fixedly installed on the output end of the first electric push rod 34, and the second electric push rod 352 is fixedly installed at both ends of the concave seat 351, and the output end of the second electric push rod 352 is fixedly installed with a clamping plate 353, and the inner middle part of the clamping plate 353 clamps the supporting steel part 37 to be welded.

[0024] The technical solution in the embodiment of the present application is used during use. When the welding mechanism 3 is in operation, the third motor 32 at the bottom of the round seat 31 is started, and its output end drives the rotating shaft 33 to rotate. The rotating shaft 33 passes through the round seat 31, so that the first electric push rod 34, the clamping group 35 and the welding group 36 fixed on the top of the rotating shaft 33 rotate together around the top plate 6 to be welded, and the clamping group 35 is moved to the outside to facilitate the placement of the supporting steel part 37 to be welded. After the supporting steel part 37 to be welded is placed inside the second electric push rods 352 at both ends of the concave seat 351, the second electric push rods are started. The output end of the rod 352 pushes the clamping plate 353 to move inward, clamping the supporting steel part 37 to be welded in the middle of the inner side of the clamping plate 353. When welding is required, the third motor 32 is started again to drive the rotating shaft 33 to rotate, so that the first electric push rod 34 drives the clamping group 35 that has clamped the supporting steel part to move toward the top plate 6 to be welded. Then, the first electric push rod 34 is controlled to extend and retract, and the distance between the clamping group 35 and the top plate 6 to be welded is accurately adjusted, so that the supporting steel part is attached to the to-be-welded part of the top plate 6 to be welded, and preparations are made for the welding group 36 to perform welding operations. Example 3

[0025] Combine Figures 1-6 As shown, the welding group 36 includes a vertical rail 361, which is fixedly installed in the middle of the concave seat 351. A fourth motor 362 is fixedly installed on the top of the vertical rail 361. The output end of the fourth motor 362 passes through the vertical rail 361 and is fixedly installed with a second screw rod 363. The two ends of the second screw rod 363 have opposite thread rotation directions. Both ends of the second screw rod 363 are threadedly connected to a sliding block 364. A double-arm welding module 365 is fixedly installed on the outer side of the sliding block 364. The double-arm welding module 365 includes a fixing frame 3651. The fixing frame 3651 is fixed. It is installed on the inner side of the sliding block 364, and both ends of the fixed frame 3651 are rotatably connected to the rotating wheel 3652. The outer side of the fixed frame 3651 is fixedly installed with a fifth motor 3653. The output end of the fifth motor 3653 is fixedly connected to the outer side of the rotating wheel 3652. The outer side of the rotating wheel 3652 is fixedly connected with a third electric push rod 3654.

Support legs 4 are fixedly installed at the four corners of the bottom of the welding table 1, and the bottom of the support legs 4 is fixedly installed with a bottom base plate 5.

[0026] According to the technical solution in the embodiment of the present application, during the use of the device, when the welding group 36 is working, the fourth motor 362 at the top of the vertical rail 361 is started, and its output end drives the second screw rod 363 to rotate. Since the threads at both ends of the second screw rod 363 rotate in opposite directions, the sliding blocks 364 at both ends will move in the opposite direction along the vertical rail 361, driving the double-arm welding module 365 fixed on the outside of the sliding block 364 to adjust up and down, thereby realizing the vertical displacement adjustment of the laser welding head 3655 to meet the welding requirements of different heights. When adjustment is required, When the angle of the laser welding head 3655 is adjusted, the fifth motor 3653 on the outside of the fixed frame 3651 is started, and its output end drives the rotating wheel 3652 to rotate, and the third electric push rod 3654 connected to the rotating wheel 3652 changes its angle accordingly, thereby driving the laser welding head 3655 to rotate, and accurately adjusting the welding angle. After determining the welding position and angle, the laser welding head 3655 is pushed to the welding position between the supporting steel part and the top plate 6 to be welded by controlling the extension and retraction of the third electric push rod 3654 to perform high-precision welding operations.

[0027] A production process for a high-strength, pressure-resistant top plate of an oven comprises the following steps: Step 1: According to the actual size of the top plate 6 to be welded, manually adjust the movable block 283 to slide within the supporting rail 282, change the sliding displacement of the clamping seat 284 on the movable block 283, and flexibly adjust the distance between the upper and lower clamping seats 284. After the distance adjustment is completed, insert the locking screw 288 on the fixing member 287 into the corresponding limit hole 289 to fix the clamping plate 285, completing the preliminary positioning and clamping of the top plate 6 to be welded; Step 2: Prepare the top plate 6 to be welded and the supporting steel parts, place the top plate 6 to be welded horizontally between the guide rollers 286 of the clamping mechanism 2, ensure that the top plate 6 to be welded is in the middle of the welding table 1, start the first motor 22, and the motor output end drives the worm 25 to rotate. The worm 25 and the worm wheel 26 are engaged and driven to make the first screw rods 24 in the side rails 23 on both sides rotate synchronously. The threads at both ends of the first screw rod 24 rotate in opposite directions, driving the sliders 27 and the clamping members 28 at both ends to move toward each other along the side rails 23 and the slide groove 21 until the clamping seat 284 and the guide rollers 286 inside the clamping plate 285 are tightly attached to the top and bottom sides of the top plate 6 to be welded; Step 3: After checking that the clamping state of the top plate 6 to be welded is correct, start the second motor 291 of the drive group 29. The second motor 291 drives the clamping plate 285 and the guide roller 286 on the clamping seat 284 to rotate through the synchronous wheel 292 and the synchronous belt 293. The L-shaped guide roller 286 is combined to make the top plate 6 to be welded move smoothly inside the guide roller 286. According to the welding requirements, the top plate 6 to be welded is adjusted to a suitable welding starting position; Step 4: Start the third motors 32 of the welding mechanisms 3 on both sides. The third motors 32 drive the rotating shafts 33 to rotate, driving the first electric push rods 34 to rotate the upper clamping group 35 and the welding group 36 around the top plate 6 to be welded, and move the clamping group 35 to the outer working position to prepare for the placement of the supporting steel parts 37 to be welded; Step 5: Accurately place the supporting steel piece 37 to be welded at the designated position between the inner sides of the two second electric push rods 352, start the second electric push rod 352, and the second electric push rod 352 pushes the inner clamping plate 353 inward to clamp and fix the supporting steel piece 37 to be welded, ensuring that the supporting steel piece remains stable during the welding process; Step 6: Start the third motor 32 again to rotate the rotating shaft 33, and drive the first electric push rod 34 to move the clamped supporting steel member 37 to be welded toward the top plate 6 to be welded. Then start the first electric push rod 34 to accurately control the supporting steel member to fit to the preset welding positions on both sides of the top plate 6 to be welded, and complete the alignment of the supporting steel member and the top plate 6 to be welded. Step 7: Start the fourth motor 362 to rotate the second screw rod 363 in the vertical rail 361. Utilizing the opposite thread rotation directions at both ends of the second screw rod 363, the sliding block 364 drives the double-arm welding module 365 to move up and down along the vertical rail 361. Adjust the vertical displacement of the laser welding head 3655 to a suitable height according to the welding process requirements. Step 8: While the laser welding head 3655 is moving up and down, the fifth motor 3653 is started to drive the rotating wheel 3652 to rotate and adjust the welding angle of the laser welding head 3655. After the angle is adjusted, the third electric push rod 3654 is extended and retracted to accurately move the laser welding head 3655 to the welding position required for the connection between the supporting steel part and the top plate 6 to be welded; Step 9: After confirming that the position and angle of the laser welding head 3655 are correct, start the welding process and perform high-precision linear motion welding on the connection between the supporting steel part and the top plate 6 to be welded, completing one welding operation; Step 10: After welding is completed, start the second motor 291 to drive the synchronous wheel 292 to rotate, drive the top plate 6 to be welded to the next welding station, and at the same time start the third motor 32 at the bottom of the round seat 31 to turn the clamping group 35 and welding group 36 at the top to the outside. The operator places a new supporting steel part 37 to be welded, repeats steps 5 to 9, and performs continuous welding processing until the welding production of the entire top plate 6 to be welded is completed.

[0028] The operating principle and advantages of the present invention are as follows: when the present device is actually used, the top plate 6 to be welded is first placed between the guide rollers 286 of the clamping mechanism 2. After the first motor 22 is started, its output end drives the worm 25 to rotate, and the worm 25 engages with the worm wheel 26, so that the first screw rods 24 in the side rails 23 on both sides rotate synchronously. Since the threads at both ends of the first screw rod 24 rotate in opposite directions, the sliders 27 at both ends drive the clamping members 28 to move toward each other along the side rails 23 and the slide grooves 21, thereby realizing the synchronous adjustment of the displacement of the clamping members 28. As the clamping seat 284 and the clamping plate 285 move inward, the guide rollers 286 on the inner side are tightly fitted to the top and bottom sides of the top plate 6 to be welded. During use, by adjusting the movable block 283 to slide in the supporting rail 282, the sliding displacement of the clamping seat 284 on the movable block 283 can be adjusted, so that the distance between the upper and lower clamping seats 284 can be adjusted. The clamping plate 285 can be flexibly changed to adapt to different sizes of top plates 6 to be welded. After the adjustment is completed, the locking screw 288 on the fixing piece 287 only needs to be inserted into the limit hole 289 to fix the clamping plate 285. When the upper and lower spacings are adjusted, and the first motor 22 completes the clamping of the top plate 6 to be welded through the linkage of the worm 25, the worm gear 26 and the first screw rod 24, the second motor 291 of the drive group 29 is started. The second motor 291 drives the clamping plate 285 and the guide roller 286 on the clamping seat 284 to rotate through the synchronous wheel 292 and the synchronous belt 293. Since the two sets of guide rollers 286 on the clamping plate 285 and the clamping seat 284 are arranged in an L shape, they can not only stably clamp and position the top and bottom sides of the top plate 6 to be welded, but also enable the top plate 6 to be welded to move smoothly inside the guide roller 286, thereby realizing the adjustment of the welding position and then realizing the automatic driving displacement of the top plate 6 to be welded; During the application of this equipment, after the top plate 6 to be welded is clamped, the welding mechanisms 3 on both sides can be started to start welding work. The third motor 32 drives the rotating shaft 33 to rotate, driving the first electric push rod 34 to make the upper clamping group 35 and the welding group 36 rotate circumferentially around the top plate 6 to be welded, and the clamping group 35 is moved to the outside. The supporting steel piece 37 to be welded is placed between the inner sides of the two second electric push rods 352, and the second electric push rod 352 is started to push the clamping plate 353 inward to complete the clamping of the supporting steel piece. After the clamping is completed, The third motor 32 is started again to drive the rotating shaft 33 to rotate, and the first electric push rod 34 is driven to move the supporting steel piece 37 to be welded toward the top plate 6 to be welded. Then the first electric push rod 34 is started to make the supporting steel piece fit to both sides of the top plate 6 to be welded. After the position is adjusted, the fourth motor 362 is started to drive the second screw rod 363 in the vertical rail 361 to rotate. The opposite thread rotation directions at the two ends of the second screw rod 363 are used to make the sliding block 364 drive the double-arm welding module 365 to move up and down along the vertical rail 361, realizing the laser welding head 365. 5 Adjustment of vertical displacement. When the laser welding head 3655 moves up and down, the fifth motor 3653 drives the rotating wheel 3652 to rotate to adjust the welding angle. After the angle is adjusted, the third electric push rod 3654 is extended and retracted to move the laser welding head 3655 to the desired welding position. By adjusting the angle and position of the laser welding head 3655 and coordinating with the linear displacement driven by the second screw rod 363, high-precision linear movement welding of the connection between the supporting steel part and the top plate 6 to be welded is achieved. After welding is completed, the second motor 291 is started to drive the synchronous wheel 292 to rotate, driving the top plate 6 to be welded to move. At the same time, the third motor 32 at the bottom of the round seat 31 is started to turn the top clamping group 35 and welding group 36 to the outside, making it easier for workers to place new supporting steel parts 37 to be welded. Repeating the above operation can perform continuous welding processing. The design of the equipment for centrally clamping the top plate 6 to be welded and the design of the welding mechanisms 3 on both sides for automatic handling and welding cooperate with each other to form a coherent automated welding process, which greatly improves the speed and quality of the welding process. During the application of this device, it adopts a bilaterally symmetrical welding mechanism 3 layout, which completely changes the limitation of the existing technology that can only weld on one side at a time. The welding mechanisms 3 on both sides operate synchronously, and there is no need to flip the top plate 6 to be welded, which saves the tedious process of manual flipping and avoids the deformation problem of the top plate 6 to be welded that may be caused by the flipping process. The double-sided welding process that was originally carried out step by step is integrated into a synchronous process, which significantly improves production efficiency. The entire clamping and welding process is highly automated, from the positioning and movement of the top plate 6 to be welded, to the feeding, clamping and welding of the supporting steel parts. They are all precisely controlled by driving elements such as motors and electric push rods, which reduces errors caused by manual operation, ensures the consistency of welding parameters, effectively improves the product qualification rate, and reduces labor costs. The L-shaped guide roller 286 cooperates with the multi-dimensionally adjustable welding module. The rolling design of the guide roller 286 reduces the movement resistance of the top plate 6 to be welded. The welding mechanism 3 can be adjusted in multiple dimensions, including horizontal, vertical and circumferential directions, which can realize rapid welding processing on both sides of the top plate 6 to be welded. The overall welding processing efficiency is relatively high, and there is no need for frequent flipping and adjustment. The overall welding processing can be fast and efficient. During the operation of this equipment, the welding table 1 has a length range of 3-5 meters and a width of 2-3.5 meters, with the side rails 23 of corresponding lengths. The diameter of the first screw 24 is 20-30 mm, the diameter of the guide roller 286 is 15-25 mm, and the spacing between the upper and lower clamping seats 284 can be adjusted from 8-50 mm. The first motor 22 has a power of 1.5-3 kW and is available in models Y132S-4 or Y132M-4. The second motor 291 has a power of 0.75-1.5 kW and is available in the Panasonic MINASA6 series MSMD012G1U or MSMD022G1U. The third motor 32 has a power of 1.1-2.2 kW and is available in models Y160M1-2 or Y160M-4. The fourth and fifth motors have a power of 0.55-1.1 kW and are available in the Panasonic MINASA6 series MSMD082G1U or MSMA042A1G. The electric actuators use AirTac SEJ16-200 / 300 / 400 models with a stroke of 200-400mm and a thrust of 800-1500N. The laser welding head 3655 uses the IPGYLR-300 / 500 / 700-QCW model. The first motor 22 is connected to a 380V AC power supply via a CHNT-CJX2-2510 / 3210 AC contactor. The servo motors are equipped with Panasonic MBDLN25SG / MBDLN35SG drivers and are powered by a 220V AC power supply through an isolation transformer. The electric actuators use APEX-ASD-075 / 150 controllers and a 24V DC power supply. The controller uses Siemens S7-1200 series CPU1214C / 1215CDC / DC / DC model PLC, which is installed in the electric control cabinet on the right side of welding table 1. It is connected to the servo drive through the PROFINET bus and the electric push rod controller through the 485 communication line. The 220V AC power is converted into 24V DC power through the Siemens 6EP1333-3BA10 / 6EP1336-3BA00 power module to power the system.
