Description

Technical Field

[0001] This utility model belongs to the technical field of welding equipment, and in particular relates to an adjustable welding roller support. Background Technology

[0002] A patent titled "A Steel Pipe Welding Fixing Support" (application number CN202122106868.8) is published in the existing Chinese patent database. This steel pipe welding fixing support includes a base, a rotating mechanism, and a fixing mechanism. The base is placed on the ground, and both the rotating and fixing mechanisms are located on the upper part of the base. The rotating mechanism is fixedly connected to the base, and the fixing mechanism is located at the front end of the rotating mechanism and fixedly connected to it. In use, the fixing mechanism secures the steel pipe, and the rotating mechanism rotates the pipe for welding. Welding can be completed without manual reversal of the pipe. If the steel pipe becomes loose during welding, an alarm will sound to warn the user and prevent it from falling and causing a safety accident. This invention is simple to operate, convenient to use, and highly practical.

[0003] During the welding process, two steel pipes of different lengths are often connected. The support spacing of the rollers in the welding bracket needs to be adjustable. In addition, the end faces of the two steel pipes need to be aligned during the welding process to facilitate welding at the aligned edges. To achieve alignment, the vertical position of the steel pipes needs to be adjusted to ensure that the end faces of the two steel pipes are accurately aligned, thereby improving the welding quality. Therefore, this solution proposes an adjustable welding roller bracket that can accommodate the welding of steel pipes of different lengths and adjust the vertical position of the two sets of steel pipes to align the end faces of the two steel pipes, thereby improving the welding quality.

[0017] The technical solution of this application will be further described below with reference to the accompanying drawings and embodiments.

[0018] like Figure 1-4As shown, an adjustable welding roller bracket includes a frame 1. A fixed roller assembly 2 is located at one end of the frame 1, and a movable roller assembly 3 is located at the other end. The movable roller assembly 3 is horizontally slidably connected to the upper surface of the frame 1. The fixed roller assembly 2 includes a fixedly mounted base 201. A positioning post 202 is bolted to the base 201 and abuts against the end face of the steel pipe to be processed. The base 201 has several connecting holes 203 spaced apart along the length of the frame 1. It also includes an adjusting plate 204 with oblong holes 205 through which several bolts are inserted. Each bolt connects to a corresponding connecting hole 203, fixing the adjusting plate 204 to the base 201. A flange connection part 206 is integrally formed at the bottom of the positioning post 202 and is bolted to the upper surface of the adjusting plate 204. The fixed roller assembly 2 includes a fixed slide 207 fixedly connected to the frame 1. A first bidirectional lead screw 208 is inserted inside the fixed slide 207. A first lead screw nut seat 209 is connected to both the positive and negative threads of the first bidirectional lead screw 208. A first roller mounting bracket 210 is fixedly connected to the upper surface of each first lead screw nut seat 209. The first roller mounting bracket 210 is slidably connected to the fixed slide 207. A support roller 211 is provided inside the first roller mounting bracket 210. A drive reducer 212 is provided outside the first roller mounting bracket 210. The shaft end of the drive reducer 212 is connected to the support roller 211. The free end of the first bidirectional lead screw 208 extends out of the fixed slide 207 and is connected to a rotating handwheel 213. The movable roller assembly 3 includes a movable slide 301. A set of slide rails 302 is fixedly installed on the upper surface of the frame 1. The length direction of the slide rails 302 is consistent with the length direction of the frame 1. A slider 303 is slidably connected to the slide rails 302. A support plate 304 is fixedly connected to the bottom of the movable slide 301. The support plate 304 and the slider 303 are connected by fasteners. A spur rack 305 is provided on the surface of the frame 1 located inside the slide rails 302. A worm gear reducer 306 is installed on the support plate 304 extending outside the movable slide 301. A gear 307 is connected to the output end of the worm gear reducer 306. The gear 307 is meshed with the spur rack 305. A second bidirectional lead screw 308 is inserted inside the movable slide 301. A second lead screw nut seat 309 is connected to both the positive and negative threads of the second bidirectional lead screw 308. A second roller mounting bracket 310 is fixedly connected to the upper surface of each second lead screw nut seat 309. The second roller mounting bracket 310 is slidably connected to the movable slide 301 and contains a rubber-coated roller 311. A baffle 4 is provided inside the fixed roller assembly 2. One end of the baffle 4 is fixedly connected to the upper surface of the base 201, and the other end is fixedly connected to the edge of the fixed slide 207.

[0019] During operation, the operator uses an external lifting device to hoist a steel pipe onto the device, so that both ends of the pipe rest on the fixed roller assembly 2 and the movable roller assembly 3 respectively. The distance between the fixed roller assembly 2 and the movable roller assembly 3 is adjusted according to the length of the steel pipe. Specifically, the operator controls the worm gear reducer 306 to drive the gear 307 to rotate. The engagement between the gear 307 and the spur rack 305 causes the movable roller assembly 3 to move along the linear direction of the spur rack 305, thereby adjusting the distance between the fixed roller assembly 2 and the movable roller assembly 3. The spacing between components 3 allows another steel pipe to be hoisted onto another identical device, aligning the end faces of the two steel pipes. When vertical alignment is not possible, rotating the handwheel 213 causes the two supporting rollers 211 in the fixed roller assembly 2 to move towards or away from each other, and the two rubber-coated rollers 311 in the movable roller assembly 3 to move towards or away from each other. This allows the vertical height of the steel pipes to be raised or lowered, thus enabling precise alignment of the end faces of the two steel pipes. The welding of the end face connection of the two steel pipes is then completed by an external robotic arm.
