Description

Technical Field

[0001] The invention relates to the technical field of welding, in particular to an intelligent welding device for a single-sided V-groove weldment with uneven groove gap. Background Art

[0002] Single-sided V-groove weldments are widely used in the fields of pipeline welding, pressure vessel manufacturing, steel structure construction, etc. This type of groove can provide good reliability for the weld, facilitate welding operation, and to a certain extent control welding deformation and ensure weld quality.

[0003] At present, the existing intelligent welding devices for single-sided V-groove weldments with uneven groove gaps usually clamp the iron plates on both sides of the welding device when performing single-sided V-groove welding on iron plates of different thicknesses, and determine the size of the groove root gap of the iron plates based on the technicians' experience. There is no standard determination, and after completing single-sided V-groove welding on iron plates of different thicknesses, the defective rate of the iron plates will be greatly increased after the weld bead PT test is performed.

[0004] Therefore, there is an urgent need for an intelligent welding device for single-sided V-groove weldments with uneven groove gaps to solve the existing technical problems. Summary of the invention

[0010] The pushing mechanism comprises a push rod and a contact block. The push rod is symmetrically distributed on one side of the surface of the clamping piece and is slidably clamped with the inside of the clamping slot.

[0011] The extrusion mechanism comprises an extrusion block, which is telescopically connected to both sides of the push rod surface and is in telescopic contact with the side of the iron plate.

The push rods are slid and adjusted on the surface of the guide rail 2 through the screw rod 2 and the slider 2, and slide and clamp into the inside of the clamping groove, while driving the clamping ring to slide and clamp into one side of the contact block surface. The contact block is squeezed by the clamping ring, and slides and adjusts on the surface of the slide rail 2 by using the slide plate and the buffer spring.

[0019] As a further improvement of the technical solution, the push rod slides toward the inner side of the clamping member along with the second screw rod and the second slider.

[0020] Compared with the prior art, the present invention has the following beneficial effects:

[0021] 1. The intelligent welding device for single-sided V-shaped groove weldment with uneven groove gap is used. The iron plate that needs single-sided V-shaped groove welding is clamped inside the clamping part. The two ends of the iron plate are flush with the two sides of the clamping part and close to one end of the inner wall of the outer side of the clamping part. First, the clamping ring and the contact block are squeezed. The contact block slides and squeezes toward one end of the iron plate with the slide plate and the buffer spring, and squeezes the other end of the iron plate from one end of the clamping part for a distance. When the extrusion block contacts the side of the iron plate, according to the different thicknesses of the iron plate, the contact block first squeezes one end of the iron plate from one end of the clamping part. At the same time, the thin iron plate can be squeezed from one end of the inner wall of the outer side of the clamping part to the inside through the extrusion block. When welding the inner wall, due to the large difference in thickness between the thin iron plate and the inside of the slot, the contact block can be used to push the thin iron plate out of one end of the slot at a longer distance, thereby achieving a small gap at the root of the groove between the thin iron plates. Conversely, the thick iron plate is affected by the shortened extrusion distance of the extrusion block into the inside of the clamp, and the contact block shortens the distance that one end of the iron plate is squeezed out from the other end of the clamp, thereby achieving a large gap at the root of the groove between the thick iron plates. This avoids the technician judging the gap at the root of the iron plate groove based on experience due to the different thickness of the iron plates, thereby improving the work efficiency of welding iron plates of different thicknesses.

[0022] 2. The intelligent welding device for the single-sided V-groove weldment with uneven groove gap is used. After the iron plate is pushed out from one end of the clamping part, it is clamped with one side of the limit plate surface, and the reset spring and the push block are used to slide and adjust on the groove surface to relieve the pressure of the contact block on the iron plate. The positioning block also has the effect of positioning and clamping the iron plate during the welding process of the welding gun, ensuring the stability of the single-sided V-groove welding of the iron plate.

[0038] The following will be combined with the accompanying drawings in the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. 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 creative work are within the scope of protection of the present invention.

[0039] See also Figure 1 - Figure 4 and Figure 7-Figure 9 As shown, the purpose of this embodiment is to provide an intelligent welding device for a single-sided V-groove weldment with uneven groove gap, including a workbench 100, a guide rail 200, a clamping mechanism 300, a pushing mechanism 400 and a squeezing mechanism 500;

[0040] A support column 101 is fixedly installed at the center position of the upper surface of the workbench 100, a power box 102 is fixedly installed at the center position of the upper surface of the support column 101, wires 103 are connected to both sides of the surface of the power box 102, a driving member 104 is fixedly connected to one side of the surface of the wire 103, a mounting member 106 is fixedly connected to one side of the surface of the driving member 104, a welding wire 107 is fixedly clamped on the surface of the mounting member 106, a welding gun 105 is fixedly installed on one side of the surface of the driving member 104, the welding guns 105 are symmetrically distributed on both sides of the upper surface of the workbench 100, and one side of the surface of the welding gun 105 is vertically corresponding to the center position of the surface of the clamping mechanism 300;

[0041] The surface of the guide rail 200 is slidably connected with a slider 203, the welding gun 105 is fixedly installed on one side of the surface of the slider 203 through the driving member 104, and the welding gun 105 is slidably adjusted up and down on the surface of the guide rail 200 through the slider 203, a servo motor 201 is fixedly installed at the center position of the upper surface of the guide rail 200, and a screw rod 202 is rotatably connected to the center position of the inner part of the guide rail 200;

[0042] The clamping mechanism 300 includes a clamping member 304, a clamping slot 306 is provided inside the clamping member 304, one side of the outer surface of the clamping slot 306 is slidably clamped with a limit plate 309, one side of the surface of the limit plate 309 is vertically corresponding to one side of the inner wall of the clamping slot 306, and an iron plate is clamped inside the clamping slot 306;

[0043] The pushing mechanism 400 includes a push rod 405 and a contact block 411. The push rod 405 is symmetrically distributed on one side of the surface of the clamping member 304 and is slidably engaged with the inside of the clamping slot 306.

[0044] The extrusion mechanism 500 includes an extrusion block 503, which is telescopically clamped on both sides of the push rod 405 and in telescopic contact with the side of the iron plate. A hydraulic pump 501 is fixedly installed inside the push rod 405, and a hydraulic telescopic rod 502 is fixedly connected to one side of the surface of the hydraulic pump 501.

[0045] By placing the iron plate at the outermost edge of the inner wall of the clamping part 304, and making the two ends of the iron plate parallel to the two ends of the clamping part 304, the contact block 411 first contacts and squeezes one side of the iron plate surface, so that one end of the iron plate can be pushed out from one end of the surface of the clamping part 304, and then the hydraulic pump 501 drives the hydraulic telescopic rod 502 to generate thrust outward, so that the extrusion block 503 pushes the iron plate toward the inner wall of the clamping groove 306, so that it is fixedly clamped at the innermost side of the inner wall of the clamping part 304, and then the welding gun 105 is used to conduct and melt the welding wire 107, and the gap at the root of the groove of the iron plate is welded;

[0046] It should be noted that the wire 103 transmits the electric energy generated by the power box 102 to the welding gun 105 through the driving member 104, and an arc is formed between the conductive tip of the welding gun 105 and the iron plate, and contacts the end of the welding wire 107, so that the welding wire 107 begins to melt, and a liquid metal bridge is formed between the welding wire 107 and the iron plate;

[0047] A proximity sensor and a visual sensor are installed on the surface of the welding gun 105. The proximity sensor performs self-inspection and calibrates the initial distance value from the iron plate to ensure that the distance between the welding gun 105 and the iron plate is always kept within an appropriate range to prevent welding defects. The visual sensor continuously monitors the groove condition. When the gap increases, the welding current and welding speed are appropriately increased to ensure the quality of weld filling. A pressure sensor is installed on the inner wall surface of the clamp 304. When the iron plate is tightly clamped to the innermost side of the inner wall of the clamp 304, the pressure change is monitored to determine whether the iron plate is firmly installed and whether it is loose during the welding process.

[0048] Therefore, based on the above structure, combined with Figure 7-Figure 8 As shown, the structure of the pushing mechanism 400 is further disclosed, the pushing mechanism 400 includes a guide rail 402, a servo motor 401 is fixedly installed on one side of the surface of the guide rail 402, a screw rod 403 is rotatably installed at the center position of the inner part of the guide rail 402, a slider 404 is rotatably sleeved on the outer surface of the screw rod 403, a push rod 405 is fixedly installed on both sides of the upper surface of the slider 404, a connecting rod 406 is fixedly connected to one side of the surface of the push rod 405, a snap ring 407 is fixedly installed on one side of the surface of the connecting rod 406, a slide rail 408 is fixedly installed on one side of the surface of the snap ring 407, a slide plate 410 is slidably connected to the surface of the slide rail 408, buffer springs 409 are connected to both sides of the surface of the slide plate 410, a contact block 411 is fixedly installed on the upper surface of the slide plate 410, and the contact block 411 is arranged on one side of the surface of the card slot 306;

[0049] Further, when the iron plate is clamped at the outermost edge of the inner wall of the clamping part 304, and the two ends of the iron plate and the two ends of the clamping part 304 are parallel to each other, the servo motor 401 is started, and the slider 404 is driven to slide and adjust on the upper surface of the guide rail 402 through the screw rod 403, and the push rod 405 is driven to slide inside the clamping part 304, and the clamping ring 407 is firstly contacted with one end of the surface of the iron plate clamped inside the clamping part 304 (Note: the size of the gap at the root of the groove is explained in detail below according to the different thickness of the iron plate, the thickness of the iron plate is 6-12mm, and the thickness of the inner part of the clamping part 304 is 15mm);

[0050] When the iron plate with a thickness of 6-8 mm is clamped on the clamping part 304, the clamping ring 407 slides with the push rod 405 and is clamped with the contact block 411, and slides on the surface of the second slide rail 408 through the buffer spring 409 and the slide plate 410, and is contacted and extruded with one side of the surface of the iron plate. During the contact and extrusion process, since the thin iron plate can slide on the inner wall of the inner side of the clamping part 304, one end of the iron plate can be pushed out to a longer distance until the extrusion block 503 fastens the iron plate to the inner wall of the inner side of the clamping part 304, and the clamping part 304 is distributed in a V-shape, which can effectively reduce the gap at the root of the groove extending from one end of the thin iron plate, thereby effectively preventing the defect of burn-through during welding;

[0051] When the iron plate with a thickness of 10-12mm is clamped on the clamping piece 304, since the thickness of the iron plate is similar to that of the clamping piece 304, after the contact block 411 pushes one end of the iron plate out of the other end of the clamping piece 304 for a certain distance, the extrusion block 503 will fasten the iron plate to the inner side of the inner wall of the clamping piece 304, thereby effectively making the gap at the root of the groove where the end of the thick iron plate extends out larger, so that the filler metal can be better spread at the root of the groove, and the problem of slag inclusion at the root caused by insufficient filling space can be effectively avoided, which is conducive to obtaining a fuller weld root shape and is helpful for improving the overall strength of the weld.

[0052] according to Fig. 9 As shown, when the thin iron plate is clamped at the outermost edge of the inner wall of the clamping piece 304, the contact block 411 is first used to generate thrust on one side of the iron plate, and the contact block 411 is pushed to the farthest distance through the second slide rail 408, so that the thin iron plate is pushed out to the farthest distance from one side of the surface of the clamping groove 306, which can shorten the distance between the ends of the welded iron plates, which is conducive to the welding gun 105 to perform single-sided V-shaped groove welding on the iron plates. At the same time, the extrusion block 503 uses the telescopic force of the hydraulic pump 501 and the hydraulic telescopic rod 502 to generate thrust on the side of the thin iron plate, and pushes it from the outermost edge of the inner wall of the clamping piece 304 to the innermost position, effectively fixing the thin iron plate in the clamping groove 306.

[0053] When the thick iron plate is clamped at the outermost edge of the inner wall of the clamping piece 304, since the thickness is almost the same as that of the clamping groove 306, when the contact block 411 pushes the iron plate out from one end of the clamping groove 306, the extrusion block 503 also pushes the iron plate from the outermost edge of the inner wall of the clamping piece 304 to the innermost position, thereby increasing the distance between the ends of the thick iron plates, playing a role of quantitative control, and being beneficial to adjusting the size of the gap at the root of the groove for iron plates of different thicknesses, and then achieving the effect of welding through the welding gun 105.

[0054] Therefore, based on the above structure, combined with Figure 4-Figure 6 As shown, the structure of the clamping mechanism 300 is further disclosed. The clamping mechanism 300 includes a slide rail 301, a slide groove 302 is provided at the center of the upper surface of the slide rail 301, a sliding member 303 is slidably connected to the upper surface of the slide groove 302, a clamping member 304 is fixedly connected to one side of the surface of the sliding member 303, a positioning block 305 is fixedly installed on one side of the surface of the clamping member 304, a groove 307 is provided on one side of the surface of the clamping groove 306, a push block 308 is slidably connected to the surface of the groove 307, and a reset spring 310 is connected to one side of the surface of the push block 308;

[0055] Furthermore, when one end of the iron plate extends out from one end of the clamping member 304, it contacts and engages with one side of the surface of the limiting plate 309, and the pushing block 308 and the return spring 310 are used to alleviate the strength of the extension of one end of the iron plate. At the same time, the positioning block 305 can ensure that the iron plate always maintains a straight line during the extension process, avoiding the problem of sliding dislocation caused by the thrust of the iron plate. In addition, during the process of single-sided V-groove welding of the iron plate by the welding gun 105, one side of the inner wall of the iron plate is clamped to ensure the stable single-sided V-groove welding of the iron plate.

[0056] It should be noted that: after the single-sided V-shaped groove welding of the iron plate is completed, the set limit plate 309 and the contact block 411 keep the two ends of the iron plate firmly clamped, and the set sliding member 303 slides out from the outer surface of the iron plate using the slide groove 302, so that the iron plate is exposed on the upper surface of the workbench 100, which is convenient for the staff to take the iron plate, and the operation is convenient and simple;

[0057] In summary, the working principle of this scheme is as follows: the iron plate that needs single-sided V-shaped groove welding is placed and clamped inside the clamping part 304, and is close to the outermost edge of the inner wall of the clamping part 304, and the two ends of the iron plate are parallel to the two ends of the clamping part 304. The servo motor 401 is started, and the slider 404 is driven to slide on the upper surface of the guide rail 402 by the screw rod 403, so that the push rod 405 slides into the inside of the clamping part 304, and the clamp ring 407 is driven to slide at the same time. Since the clamp ring 407 is set at one end of the outer surface of the push rod 405, First, the contact block 411 contacts and squeezes the surface of the contact block 411. Under the connection of the slide plate 410 and the buffer spring 409, the contact block 411 is first squeezed toward one side of the iron plate surface, and one end of the iron plate is pushed out from one end of the clamping member 304. After the contact block 411 squeezes a certain distance according to the iron plates of different thicknesses, the squeezing block 503 contacts and squeezes the side of the iron plate through the hydraulic pump 501 and the hydraulic telescopic rod 502, squeezing the iron plate from the outermost edge of the inner wall of the clamping member 304 to the innermost side of the inner wall, and then the iron plate is fastened and clamped inside the clamping member 304.

[0058] After one end of the iron plate is squeezed out from one end of the clamping member 304, it contacts and squeezes the surface of the limit plate 309. Under the connection between the push block 308 and the return spring 310, the strength of the iron plate being pushed out is relieved and reduced, and the intersection position of one end of the iron plate being pushed out is vertically aligned with the surface of the welding gun 105.

[0059] The power box 102 and the welding gun 105 are electrically connected through the wire 103, and the current is conducted to the surface of the welding gun 105 and contacts the surface of the welding wire 107. The welding wire 107 begins to melt, and a liquid metal bridge is formed between the welding wire 107 and the iron plate. When the single-sided V-groove welding of the iron plate is completed, the set limit plate 309 and the contact block 411 keep the two ends of the iron plate firmly clamped, and the set sliding member 303 slides out from the outer surface of the iron plate using the slide groove 302, so that the iron plate is exposed on the upper surface of the workbench 100, which is convenient for the staff to take the iron plate, and the operation is convenient and simple.
