Description

Technical Field

[0001] The invention relates to the field of welding, and in particular to welding equipment for steel structure processing. Background Art

[0002] A laser welding gun is a tool that uses a laser beam for welding, which can achieve precise and efficient welding results.

[0003] Existing laser welding guns usually use a single-point support method during the welding process, that is, the welding wire is pushed against the welding area through the welding nozzle, and welding is performed as the laser welding gun moves slowly. However, when welding long steel plates, the welding point is easily affected by the shaking of the worker's arm and causes deviation and swing, resulting in skewed and offset welds; this not only affects the appearance of the weld, but also reduces the quality of the welding.

[0004] In addition, when welding two steel plates, workers usually clamp and fix the two ends of the steel plates. However, when the steel plates are relatively thin, only clamping and fixing the two ends may cause gaps in the middle of the steel plates, which will affect the progress of welding and the welding quality. Summary of the invention

[0005] In order to overcome the disadvantage that the existing laser welding guns usually adopt a single-point support method, the welding point is easily affected by the shaking of the worker's arm and produces deviation and swing, which causes the welded weld to be skewed and offset, which not only affects the appearance of the weld but also reduces the quality of welding. The present invention provides a welding device for steel structure processing.

[0006] The technical solution is as follows: A welding equipment for steel structure processing, including a laser welding gun, a wire feeding tube and a control button; the laser welding gun is rotatably connected to a wire feeding tube for conveying welding rods; a control button is provided on the handle of the laser welding gun; it also includes a slide rail, a first electric slider, a fixed block, a second electric slider, a clamping block and a rotating wheel; the slide rail is fixedly connected to the wire feeding tube; the slide rail is slidably connected to the first electric slider; the fixed block is fixedly connected to the first electric slider; the second electric slider is slidably connected in the fixed block; a clamping block for clamping a thinner steel plate is fixedly connected to the lower side of each second electric slider; and a rotating wheel for providing additional support is rotatably connected to the lower side of each clamping block.

[0007] Optionally, it also includes a shielding plate and a partition cover; a welding nozzle is arranged on the front side of the laser welding gun; a first air outlet is arranged in the welding nozzle; a shielding plate is fixedly connected to the outer side of the welding nozzle; a second air outlet is formed between the shielding plate and the outer surface of the welding nozzle; a plurality of through grooves are opened on the welding nozzle; and a partition cover is fixedly connected to the welding nozzle.

[0008] Optionally, the shielding plate is made of transparent material.

[0009] Optionally, it also includes a limit plate, a spring telescopic rod and a cutter; the lower side of the shielding plate is slidably connected to the limit plate; a spring telescopic rod is fixed between the limit plate and the shielding plate; a cutter for cutting the welding wire is fixed to the lower side of the shielding plate; the cutter is located above the left side of the limit plate.

[0010] Optionally, a rotating roller is also included; the lower side of the limiting plate is rotatably connected to the rotating roller.

[0011] Optionally, it also includes protrusions; and a plurality of protrusions are fixedly connected to the facing sides of the two clamping blocks.

[0012] Optionally, balls are also included; the opposite sides of the two second electric sliders are rotatably connected with the balls.

[0013] Optionally, an infrared aligner is also included; the infrared aligner is fixedly connected to the lower left side of the wire feeding tube.

[0014] Optionally, a friction block is also included; a plurality of friction blocks are fixedly connected to the handle of the laser welding gun.

[0015] Optionally, a sponge pad is also included; the sponge pad is fixedly connected to the lower left side of the laser welding gun.

[0016] Compared with the prior art, the present invention has the following advantages: the present invention realizes that the rotating wheel and the welding nozzle form two supporting points through the fixed block and the rotating wheel when the laser welding gun performs welding work, and the two points determine a straight line, and the rotating wheel can only perform linear motion and cannot rotate, so during the welding process, even if the worker's arm shakes, it will not have a significant impact on the welding point; and the rotating wheel makes it possible for the welding nozzle and the welding surface of the steel plate to always form an angle of 45°; the single-point support method in the prior art is solved, which requires the worker to control the welding angle by himself, making it difficult for the worker to maintain the optimal welding angle during welding;

[0017] During welding, the inert gas is guided through the separation hood and the shielding plate, which not only increases the coverage of the inert gas, but also guides the inert gas outward from the middle of the welding point to blow away the slag generated by welding, greatly improving the welding quality. The shielding plate can shield the sparks generated by welding to protect the workers.

[0018] The clamping block is driven to move by the second electric slider; and when welding thinner steel plates, the steel plates are clamped and welded; a large gap in the middle of the steel plate is avoided to affect the welding quality; and when the welding angle is at the position, the two second electric sliders are pushed to the opposite sides so that the ball is fitted to the surface of the steel plate, thereby forming a triangular support shape, thereby improving the stability of the laser welding gun during welding and improving the welding effect; and through this method, the laser welding gun can adapt to a variety of complex welding environments during welding, greatly improving the stability of the welding point, and improving the adaptability and practicality of the laser welding gun.

DETAILED DESCRIPTION

[0032] It also includes a shielding plate 101 and a separating cover 102; a welding nozzle 1001 is arranged on the front side of the laser welding gun 1; a first air outlet 1002 is arranged in the welding nozzle 1001; a shielding plate 101 is fixedly connected to the outer side of the welding nozzle 1001, and the shielding plate 101 is funnel-shaped; a second air outlet 10101 is formed between the shielding plate 101 and the outer surface of the welding nozzle 1001; four through grooves 1003 are opened on the welding nozzle 1001; a separating cover 102 is fixedly connected to the welding nozzle 1001, and the airflow is guided to the through grooves 1003 through the separating cover 102, and then from the second air outlet 10101.

[0033] The shielding plate 101 is made of transparent material.

[0034] It also includes a limit plate 103, a spring telescopic rod 105 and a cutter 106; the lower side of the shielding plate 101 is slidably connected to the limit plate 103; the spring telescopic rod 105 is fixed between the limit plate 103 and the shielding plate 101; the cutter 106 is fixed to the lower side of the shielding plate 101; the cutter 106 is located above the left side of the limit plate 103.

[0035] It also includes a rotating roller 104 ; the lower side of the limiting plate 103 is rotatably connected to the rotating roller 104 .

[0036] It also includes protrusions 204; a plurality of protrusions 204 are fixedly connected to the facing sides of the two clamping blocks 202, and the surfaces of the protrusions 204 are smooth.

[0037] The second electric sliders 201 further include a ball bearing 205 ; the opposite sides of the two second electric sliders 201 are both rotatably connected with the ball bearing 205 .

[0038] The existing laser welding gun 1 usually adopts a single-point support method during the welding process, that is, the welding wire 666 is pushed against the welding area through the welding nozzle 1001, and the welding is performed as the laser welding gun 1 moves slowly. However, when welding a long steel plate 555, the welding point is easily affected by the shaking of the worker's arm and causes deviation and swing, resulting in the phenomenon of skewness and deviation of the welded seam; this not only affects the appearance of the weld, but also reduces the quality of the welding.

[0039] To solve the above problem, the present invention proposes the following method: first, the worker connects the laser welding gun 1 to the external power supply and the external air pump; then installs the welding wire 666 in the wire feeding tube 2. During this process, the worker can rotate the angle of the wire feeding tube 2 to facilitate the installation of the welding wire 666. After the welding wire 666 is installed, the angle of the wire feeding tube 2 is adjusted. Figure 2 As shown: the welding wire 666 is pressed against the lower side of the limit plate 103; then the worker pushes the welding wire 666 against the welding area through the limit plate 103; at this time Figure 1 and Figure 2 As shown: the worker can control the first electric slider 108 to slide left and right on the slide rail 107 through the control button 3, thereby driving the fixed block 109 and the rotating wheel 203 to move left and right. At this time, the rotating wheel 203 contacts the surface of the steel plate 555 and moves on the surface of the steel plate 555. It should be noted that during this process, the worker needs to adjust the support point of the laser welding gun 1 to the rotating wheel 203 so that the rotating wheel 203 fits the surface of the steel plate 555. When the rotating wheel 203 moves to the position where the welding nozzle 1001 and the welding surface of the steel plate 555 form an angle of 45°, the first electric slider 108 stops sliding; then the worker performs welding work again. During the welding process, the rotating wheel 203 and the welding nozzle 1001 form two support points. , and the two points determine a straight line, and the rotating wheel 203 can only move in a straight line and cannot rotate. Therefore, during the welding process, even if the worker's arm shakes, it will not have a significant impact on the welding point; avoid the phenomenon of skewness and offset of the welding point during the welding process, which affects the appearance of the weld and reduces the quality of welding; at the same time, during the welding process, the rotating wheel 203 is used to ensure that the welding nozzle 1001 and the welding surface of the steel plate 555 always form a 45° angle; and in the industry, the 45° angle between the welding nozzle 1001 and the welding surface is usually considered to be the best welding angle; it solves the problem of the single-point support method in the prior art, which requires workers to control the welding angle by themselves, making it difficult for workers to maintain the best welding angle during welding.

[0040] At the same time, during the welding process, an inert gas such as argon is fed into the laser welding gun 1 through an external air pump and ejected through the first air outlet 1002, thereby preventing oxidation of the material during the welding process and ensuring the welding quality; and Figure 3 As shown: when the inert gas is ejected through the first gas outlet 1002, the inert gas is introduced into the through groove 1003 through the separation cover 102, and is ejected through the second gas outlet 10101; at this time, the inert gas is guided by the funnel-shaped shielding plate 101, which not only increases the coverage of the inert gas, but also guides the inert gas from the middle of the welding point to the outside, and blows out the slag produced by the welding, which greatly improves the welding quality, and the shielding plate 101 can shield the sparks produced by the welding to protect the workers, and the shielding plate 101 is made of transparent material and will not affect the workers' inspection of the welding conditions at the welding points.

[0041] And if Figure 3-Figure 6 As shown: During the welding process, the worker needs to support the main supporting force at the rotating wheel 203. At this time, the limit plate 103 is an auxiliary supporting point. Therefore, the extrusion force of the welding wire 666 on the limit plate 103 is not large, and the limit plate 103 is supported by the spring telescopic rod 105 to be pushed downward. Therefore, the welding wire 666 will not contact the cutter 106 at this time. When the welding is completed, the worker can replace the main supporting point with the limit plate 103. At this time, the worker first turns off the laser welding gun 1, and then presses the laser welding gun 1 toward the limit plate 103. At this time, the spring telescopic rod 105 is compressed and contracted, and the limit plate 103 moves upward. The cutter 106 contacts and cuts off the welding wire 666, so as to avoid some unskilled novices who cannot quickly melt the welding wire 666 after welding when using the laser welding gun 1, resulting in the phenomenon of wire drawing of the welding wire 666, which affects the appearance and welding quality.

[0042] In addition, when welding two steel plates 555, workers usually clamp and fix the two ends of the steel plate 555; however, when the steel plate 555 is relatively thin, only clamping and fixing the two ends may cause a gap in the middle of the steel plate 555, which affects the progress of the welding work and the welding quality. Figure 5 and Figure 6 As shown: the worker can control the second electric slider 201 through the control button 3 to drive the clamping block 202 to move, open the clamping block 202, and then put the clamping block 202 on both sides of the thinner steel plate 555, and then control the second electric slider 201 to drive the clamping block 202 to move, clamp the steel plate 555, and then clamp and weld the thinner steel plate 555; avoid a large gap in the middle of the steel plate 555 that affects the welding quality; and during the clamping process, the protrusion 204 is used to improve the clamping effect of the clamping block 202 on the steel plate 555, and the surface of the protrusion 204 is a smooth surface, which is convenient for subsequent workers to drive the laser welding gun 1 to move for welding.

[0043] When welding at an angle, the worker can align the laser welding gun 1 to a good position and then control the two second electric slides 201 to push out to opposite sides through the control button 3, so that the ball 205 fits the surface of the steel plate 555, thereby forming a Figure 8 The triangular support shape shown improves the stability of the laser welding gun 1 during welding and improves the welding effect; further, through this method, the laser welding gun 1 can adapt to a variety of complex welding environments during welding, greatly improving the stability of the weld point and improving the adaptability and practicality of the laser welding gun 1.

[0044] Example 2

[0045] On the basis of Example 1, Figure 1 and Figure 5 As shown, an infrared ray aligner 206 is also included; the infrared ray aligner 206 is fixedly connected to the lower left side of the wire feeding tube 2.

[0046] It also includes a friction block 207; a plurality of friction blocks 207 are fixedly connected to the handle of the laser welding gun 1, and the friction blocks 207 are made of sponge material.

[0047] A sponge pad 208 is also included; the sponge pad 208 is fixedly connected to the lower left side of the laser welding gun 1 .

[0048] During the welding process, the worker can turn on the infrared aligner 206, and then the infrared aligner 206 will emit infrared laser to the weld position, thereby providing a reference for the worker when welding. The worker only needs to keep the infrared at the weld to perform welding work more accurately.

[0049] During welding, the friction block 207 is used to increase the friction of the worker holding the laser welding gun 1 and improve stability. The friction block 207 is made of sponge material, which greatly improves the comfort of the worker holding the laser welding gun 1. When the worker presses down the laser welding gun 1, the welding wire 666 is pressed against the welding area through the limit plate 103. During welding, the pressing action will cause the worker's wrist to naturally tilt upward toward the upper part of the laser welding gun 1. At this time, the sponge pad 208 provides a gasket for the worker's arm, thereby preventing the worker's arm from pressing against the tail of the metal laser welding gun 1 and causing damage to the worker's arm.

Any equivalent structure or equivalent process transformation made using the contents of the present invention specification, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
