Abstract
Description
Technical Field
[0001] This utility model relates to the field of steel structure processing technology, specifically to a welding device for steel structure processing. Background Technology
[0002] In the field of steel structure fabrication, welding is one of the key processes for connecting steel structure components. Steel structures, due to their high strength, light weight, and ease of construction, are widely used in various fields such as large factories, stadiums, and high-rise buildings. However, welding technology faces numerous challenges during the fabrication of steel structures.
[0003] The prior art, disclosed in publication number CN217727617U, is a welding device for steel structure processing, relating to the field of steel structure processing technology. This welding device for steel structure processing includes an operating table and a drive mechanism. The operating table is equipped with a placement mechanism and a drive mechanism, on which an electric welding machine is mounted. An anti-splatter mechanism is also provided on the operating table. The drive mechanism includes a longitudinal adjustment component and a lateral adjustment component, the longitudinal adjustment component driving the lateral adjustment component to move vertically relative to the operating table. On the one hand, this device significantly reduces reliance on highly skilled workers, eliminating the need to hire a large number of technical personnel, thus reducing labor costs and processing expenses. On the other hand, the device allows for adjustment of the electric welding machine in four directions (up, down, left, and right), eliminating the need for workers to manually hold the welding machine while welding steel plates, greatly reducing the daily workload of workers.
[0004] However, the aforementioned welding device for steel structure processing, which involves an operating table, placement mechanism, drive mechanism, longitudinal adjustment components, transverse adjustment components, and welding machine, greatly reduces the reliance on highly skilled workers. However, the lack of positioning sensors during adjustment means that users cannot accurately adjust the position of the welding components according to different steel structure dimensions to achieve precise welding, resulting in poor welding accuracy and unsatisfactory performance. Therefore, improvements are needed. Utility Model Content

[0023] Please see Figure 1-4 The present invention provides the following technical solution:
[0024] A welding device for steel structure processing includes a welding box 1, an internal positioning device 2 is provided at the bottom of the welding box 1, and a welding device 3 is provided at the top of the welding box 1.
[0025] The internal positioning and placement device 2 includes a support frame 201, a connecting plate 202, a first hydraulic telescopic rod 203, a clamping and placement plate 204, a rear fixed clamping and placement plate 205, a side limiting plate 206, a placement box 207, and a position detection sensor 208. The support frame 201 is fixedly connected to the bottom of the welded box 1. The connecting plate 202 is fixedly connected to the top of the support frame 201 near the front. The first hydraulic telescopic rod 203 is fixedly connected to the inside of the connecting plate 202. The clamping and placement plate 204 is fixedly connected to the back of the first hydraulic telescopic rod 203. The rear fixed clamping and placement plate 205 is fixedly connected to the top back of the support frame 201. The side limiting plate 206 is fixedly connected to the bottom of the box 1. The placement box 207 is fixedly connected to the left side of the side limiting plate 206 and attached to the top of the support frame 201. The position detection sensor 208 is connected to the inside of the placement box 207. The position detection sensors 208 are arranged in an equally spaced array inside the placement box 207. The position detection sensor 208 is the farthest end of the upper welding component adjustment. When the position of the welding gun 307 is detected, it indicates that the upper welding component has shifted and the position of the welding component needs to be adjusted. The position detection sensor 208 plays the role of position detection to avoid shift. The top of the support frame 201 is provided with a sliding groove. The right side of the left side limiting plate 206 is aligned with the inner left side of the sliding groove.
[0026] Welding device 3 includes a second hydraulic telescopic rod 301, a rectangular adjusting frame 302, a connecting strip 303, a limiting slider 304, a connecting crossbar 305, a third hydraulic telescopic rod 306, a welding torch 307, and a top support plate 308. The top support plate 308 is fixedly connected to the top of the inner wall of the welding box 1. The second hydraulic telescopic rod 301 is fixedly connected to the inside of the top support plate 308. The connecting strip 303 is fixedly connected to the bottom of the second hydraulic telescopic rod 301. The third hydraulic telescopic rod 306 is fixedly connected to the top of the rectangular adjusting frame 302 near the back. The adjusting frame 302 is fixedly connected to both sides of the surface of the connecting strip 303. The limiting slider 304 is slidably connected to the inside of the rectangular adjusting frame 302. The connecting crossbar 305 is fixedly connected to the front of the third hydraulic telescopic rod 306. The welding gun 307 is fixedly connected to the front of the limiting slider 304. The connecting crossbar 305 is fixedly connected to the top side of the limiting slider 304. The connecting crossbar 305 is slidably connected to the top of the rectangular adjusting frame 302. The purpose of the connecting crossbar 305 is to start the connection and limit the sliding, ensuring the stability of the sliding. The connecting strip 303 serves as a barrier.
[0027] In use, the steel structure to be welded is placed on the surface of the rear fixed clamping plate 205. Then, the first hydraulic telescopic rod 203 is activated to move the clamping plate 204 backward until the supporting U-shaped frame on the back of the clamping plate 204 contacts the front of the steel structure, thereby clamping and fixing it. The side is limited by the side end limiting plate 206, which also serves as heat insulation. The internal groove is used during demolding. A placement box 207 and a position detection sensor 208 are set on the top side of the side end limiting plate 206. The position detection sensor 208 is the farthest point of the upper welding assembly adjustment. When the position of the welding gun 307 is detected, it indicates that the upper welding assembly has shifted, and the position of the welding assembly needs to be adjusted. The position detection sensor 208 plays a role in position detection to prevent shifting. The upper welding device 3 can be raised and lowered to assist welding. It can be activated during use. The second hydraulic telescopic rod 301 drives the rectangular adjustment frame 302 to move downwards, bringing the rectangular adjustment frame 302 and the welding torch 307 at the bottom closer to the junction of the steel structure to be welded. Then, the third hydraulic telescopic rod 306 is driven to move the welding torch 307 to the rearmost position. Then, the third hydraulic telescopic rod 306 is started to move forward while the welding torch 307 is started to weld from back to front. The purpose of the connecting crossbeam 305 is to start the connection and limit the sliding, ensuring stable sliding. The connecting strip 303 serves as a barrier. The distance between the back of the connecting strip 303 and the third hydraulic telescopic rod 306 is exactly the distance between the back of the clamping plate 204 and the rear fixed clamping plate 205, controlling the movement of the welding components and avoiding excessive movement that could damage the welding. The components are equipped with positioning sensors during adjustment, allowing users to adjust the position of the welding components according to different steel structure dimensions to achieve precise welding with good welding accuracy.
