Description

Technical Field

[0001] The present invention relates to the field of welding technology, and particularly to an intelligent single-bar welding device. Background Art

[0002] The production of single bars is usually by welding. Different specifications of steel pipes or rod-shaped materials are formed through splicing and riveting welding. The welding of single bars is either long or short, and the welding direction is either horizontal or vertical. Therefore, during welding, it is not only necessary to stably and accurately correct and clamp the workpieces to be welded, but also to transform and adjust the real-time direction and orientation of the welding equipment to meet the welding of steel pipes with different specifications and different directions.

[0003] To solve the above problems, a Chinese invention patent with the publication number CN111112800A discloses an argon arc welding intelligent welding device, which includes a welding manipulator and a roller rack arranged below the manipulator. The welding manipulator is composed of a support column arranged on the ground and a support arm arranged on the support column. The support arm is fixed by 4 positioning blocks in the up, down, left, and right directions, and an argon arc welding head is provided at the front end of the support arm. The argon arc welding head faces the roller rack below. The welding manipulator, the argon arc welding head, and the roller rack are all controlled by a PLC electric control system. However, this invention does not make a design for real-time adjustment of the welding orientation and direction of the profiled materials to be welded. Therefore, the present invention provides an intelligent single-bar welding device. Summary of the Invention

A first welding torch 108 and a second welding torch 109 are fixedly installed on each swing rod 119.

[0028] On the calibration mechanism 2, there is a calibration guide plate 202 fixedly installed on the calibration base 201. There are two calibration guide plates 202 and two calibration slide plates 203. There is a round hole on the calibration guide plate 202. Around the round hole of each calibration guide plate 202, three sliding grooves are evenly arranged. The center lines of the three sliding grooves intersect at the center of the round hole of the calibration guide plate 202. There is a round groove on the calibration slide plate 203. The round groove of the calibration slide plate 203 is coaxial with the round hole of the calibration guide plate 202. There are three inclined grooves on each calibration slide plate 203. There are three rollers 204. One end of each roller 204 is slidably installed in the sliding groove of one calibration guide plate 202 and the inclined groove of the calibration slide plate 203 at the same time. The other end of each roller 204 is slidably installed in the sliding groove of the other calibration guide plate 202 at the corresponding position and the inclined groove of the calibration slide plate 203 at the same time. A limit piece 207 is fixedly installed at both ends of each roller 204. The limit piece 207 is located between the calibration guide plate 202 and the calibration slide plate 203. The two calibration slide plates 203 are fixedly connected by a calibration connecting rod 206. The calibration connecting rod 206 is rotatably connected to the piston rod of the calibration cylinder 205. The calibration cylinder 205 is rotatably installed on the calibration base 201. One of the calibration slide plates 203 is fixedly connected to the gear disk 301.

[0029] On the clamping mechanism 3, there are four clamping gears 305 that mesh with the gear disk 301. Each clamping gear 305 meshes with a clamping rack 304. A holding piece 306 is fixedly installed on each clamping rack 304. The holding piece 306 is slidably installed in the clamping guide groove 307. The clamping guide grooves 307 are evenly arranged on the sliding disk 303. The sliding disk 303 is fixedly connected to the clamping base 302. A clamping ring 308 is fixedly installed on the sliding disk 303. There are four hole grooves corresponding to the positions of the clamping guide grooves 307 on the clamping ring 308.

The clamping ring 308, the sliding disk 303, the round groove of the calibration slide plate 203, and the round hole of the calibration guide plate 202 are coaxial.

[0030] When the present invention is in use, the guide rail frame 101 is installed on the ground. Taking the main beam of a single pole as an example, the main beam of the horizontal bar is passed through the round hole of the calibration guide plate 202, the round groove of the calibration slide plate 203, the sliding disk 303, and the clamping ring 308. The calibration cylinder 205 is started. The calibration cylinder 205 extends the piston rod to push the calibration connecting rod 206, driving the two calibration slide plates 203 to rotate. The two ends of the roller 204 are pushed by the inclined grooves on the two calibration slide plates 203 to slide in the sliding grooves of the calibration guide plate 202, so that the three rollers 204 gradually approach, making the surface of the roller 204 close to the outer surface of the main beam, calibrating the position of the main beam, making the main beam coaxial with the round groove of the calibration slide plate 203 and the round hole of the calibration guide plate 202, and reducing the welding deformation amount.

[0031] Meanwhile, the rotating calibration slide plate 203 drives the gear disk 301 to rotate. The gear disk 301 drives the four clamping gears 305 to rotate, driving the four clamping racks 304 and the clamping pieces 306 to slide on the clamping guide grooves 307 until the clamping pieces 306 clamp the main beam, fixing the position of the main beam. Subsequently, the traveling motor 116 is started to drive the first traveling gear 113 to rotate, driving the second traveling gear 114 to rotate, driving the third traveling gear 115 to rotate, and driving the traveling wheels 103 to rotate, thereby driving the traveling wheels 103 to travel along the track of the guide rail frame 101; the four guide wheels 102 installed on the welding carriage 104 closely adhere to the inner wall of the guide rail frame 101 for guiding and turning. The position and direction of the welding torch are adjusted according to the position of the welded part and the direction of the weld seam, so that the welding mechanism 1 travels to the welding position. After docking another welded part with the main beam, the welding cylinder 112 is started at the welding position, and the welding push rod 111 is driven to drive the welding connecting rods 110 on both sides to swing, driving the sliding seat 117 to slide towards each other along the slide rod 118, driving the two welding racks 106 to move synchronously, driving the two welding gears 107 to rotate, driving the two swing rods 119 to swing, driving the two welding torches 108 and 109 to adjust the angle and position, and performing synchronous welding after aligning the position, so that the weld seam is quickly formed.

For those skilled in the art, the technical solutions recorded in the above embodiments can be modified, or some of the technical features can be equivalently replaced; and all such modifications and replacements should fall within the protection scope of the appended claims of the present invention.
