Description

Technical Field

[0001] This utility model belongs to the field of steel profile processing technology, and specifically relates to a welding device. Background Technology

[0002] A steel profile welding device is a specialized piece of equipment designed to precisely butt and weld two or more steel profiles. This device typically includes a clamping system, a welding machine, and a control system to ensure stability and precision during the welding process. Its main functions are to guarantee welding quality, improve work efficiency, and reduce errors caused by manual operation.

[0003] Existing steel profile welding equipment clamps and fixes two steel profiles, then welds them together at the joint of the two steel profiles using a downward-moving welding machine. After one side is welded, personnel must release the clamps and manually adjust the other three unwelded sides of the steel profiles to align with the welding machine before welding again. This repeated adjustment and re-clamping increases the downtime of the steel profile welding production equipment, reduces welding efficiency, and the frequent manual adjustments not only consume a lot of manpower but also easily cause worker fatigue, affecting work quality and safety.

[0019] To better understand this utility model, the following embodiments further illustrate its content, but the scope of protection of this utility model is not limited to the embodiments described below. Numerous specific details are set forth in the following description to provide a more thorough understanding of this utility model. However, it will be apparent to those skilled in the art that this utility model can be practiced without one or more of these details.

[0020] like Figure 1 , 3 As shown in Figure 4, a welding device includes a support box 101. A drive box 201 is provided at the upper end of the support box 101. A rotating cylinder 204 is rotatably arranged inside the drive box 201. A sliding frame 207 is provided at the right end of the rotating cylinder 204. A sliding frame 208 is slidably arranged inside the sliding frame 207. A plurality of guide posts 209 are slidably arranged inside the sliding frame 208. A welding machine 211 is arranged between the lower ends of the plurality of guide posts 209. A drive welding machine 21 is arranged inside the drive box 201. 1. A circular motion drive mechanism 1, and a linear motion drive mechanism 2 for driving the welding machine 211 is provided inside the slide frame 207. The drive mechanism 2 includes a lead screw 212 rotatably disposed inside the slide frame 207. The sliding frame 208 is threadedly connected to the lead screw 212. A drive unit 2 for driving the lead screw 212 to rotate is provided on the rear side of the slide frame 207. The drive unit 2 includes a motor 203 disposed on the rear side of the slide frame 207. The output shaft of the motor 203 is connected to the rear end of the lead screw 212 through a coupling.

[0021] like Figure 1 , 2As shown, the drive mechanism includes a gear 206 rotatably disposed inside the drive housing 201. An external gear ring 205 is disposed on the outer arc surface of the rotating drum 204, and the external gear ring 205 meshes with the gear 206. A drive unit 1 for driving the gear 206 to rotate is disposed on the left side of the drive housing 201. The drive unit 1 includes a motor 202 disposed on the left side of the drive housing 201. The output shaft of the motor 202 is connected to the left end of the gear 206 through a coupling. An electric push rod 210 is disposed inside the sliding frame 208. The telescopic end of the electric push rod 210 is connected to the upper end of the welding machine 211.

[0022] like Figure 1 As shown, the upper end of the carrier box 101 is provided with multiple placement plates 301. Multiple guide posts 302 are slidably arranged inside the multiple placement plates 301. A clamping and fixing plate 303 is respectively arranged between the multiple guide posts 302 located on the left and right sides inside the same placement plate 301. The guide posts 302 and the clamping and fixing plates 303 are fixed by welding. Electric push rods 304 are respectively arranged on the front and rear sides of the multiple placement plates 301. The telescopic ends of the multiple electric push rods 304 are respectively connected to the rear side of the adjacent clamping and fixing plates 303.

[0023] By placing two steel profiles to be welded on the placement plates 301 on both sides and joining them together, so that the joint is located at the lower end of the welding machine 211, the electric push rod 304 is opened by control, and the telescopic end drives the clamping and fixing plate 303 to move closer to each other under the restriction of the guide column 302 to clamp the steel profiles.
