[0031] In order to further explain the technical means and effects adopted by the present invention to achieve the predetermined purpose of the utility model, the specific implementation method, structure, characteristics and effects of the present invention are described in detail below in combination with the accompanying drawings and preferred embodiments.

[0032] See also Figures 1 to 8 FIG. 1 shows a welding positioner capable of automatically adjusting the welding posture of a steel member to be welded, comprising a machine body 1, the machine body 1 comprising a frame 11, a bottom plate 12 is fixedly mounted below the frame 11, a first motor 14 is fixedly mounted above the bottom plate 12, a first cylinder 13 is fixedly mounted above the frame 11, and a first annular groove 15 is provided on the surface of the frame 11, a second annular groove 16 is provided through the first annular groove 15, and the width of the second annular groove 16 is smaller than the width of the first annular groove 15;

[0033] It also includes an adjustment mechanism 2, which is fixedly mounted above the frame 11, and a first cylinder 13 can drive the adjustment mechanism 2 to move up and down; specifically:

[0034] The adjustment mechanism 2 includes a plurality of moving rods 23. In this embodiment, there are four moving rods 23. The more moving rods 23 there are, the more stable the machine is. The moving rods 23 are all fixedly mounted on the surface of the frame 11. The moving rod 23 is located in the middle of the first annular groove 15, and a second slide groove 2301 is provided on one side of the moving rod 23. Space is reserved between the second slide groove 2301 and the top of the moving rod 23 to prevent the slider from falling off during movement. The adjustment mechanism 2 includes a moving plate 22. The four corners of the moving plate 22 are all fixedly mounted with second sliders 2201. The second sliders 2201 are adapted to the second slide groove 2301 and are all T-shaped. First slide grooves 2202 are provided on both sides of the bottom of the moving plate 22, and second cylinders 2203 are fixedly mounted on one end of the first slide grooves 2202 on both sides. When the first cylinder 13 is started, the cylinder 13 drives the moving plate 23 to move upward or downward, and the second slider 2201 moves upward or downward in the second slide groove 2301 accordingly.

[0035] The adjustment mechanism 2 further includes a rotating member 21, which includes two side plates 2101, which are fixedly mounted on the moving plate 22, a rotating rod 2106 is rotatably mounted between the two side plates 2101, a welding plate 2105 is fixedly mounted on the rotating rod 2106, and a second motor 2104 is fixedly mounted on the outer side of the side plates 2101, and the output shaft of the second motor 2104 is coaxially connected to the rotating rod 2106. When the second motor 2104 is started, the second motor 2104 can drive the rotating rod 2106 to rotate, and because the rotating rod 2106 is fixedly connected to the welding plate 2105, the welding plate 2105 will also rotate accordingly.

[0036] The outer sides of the two side plates 2101 are fixedly mounted with a U-shaped plate 2102, one end of the U-shaped plate 2102 is fixedly mounted with a first slider 2103, and the second cylinder 2203 can drive the first slider 2103 to move forward and backward in the first slide groove 2202. The second cylinders 2203 in the two first slide grooves 2202 need to be started at the same time. When the second cylinders 2203 are started, the rotating member 21 will move horizontally, and the first slider 2103 will move back and forth in the first slide groove 2202.

[0037] To ensure that the steel structure to be welded can be welded in any desired posture, it also includes a welding part 3, which includes a fixed plate 31, which is coaxially connected to the output shaft of the first motor 14, and the length of the fixed plate 31 is the same as the radius length of the second annular groove 16. The first motor 14 can drive the welding part 3 to move along the first annular groove 15. When the first motor 14 is started, the welding part 3 can be driven to make a circular motion along the first annular groove 15. A connecting rod 32 is fixedly installed above one end of the fixed plate 31, and the connecting rod 32 is located in the middle of the second annular groove 16. In this way, the moving path of the connecting rod 32 is precisely defined in the second annular groove 16, ensuring that it moves along a preset trajectory when the fixed plate 31 rotates. A rolling ball 33 is fixedly installed on the connecting rod 32, and the rolling ball 33 is located in the first annular groove 15. The rolling ball 33 can reduce the friction resistance of the connecting rod 32 when it moves in the first annular groove 15, ensuring that its movement is smoother and more precise. At the same time, the contact mode between the rolling ball 33 and the first annular groove 15 also helps to disperse stress and prolong the service life of the equipment. A welding pen 34 is fixedly installed above the rolling ball 33. The connecting rod 31 rotates along the second annular groove 16 under the drive of the first motor 14, and the rolling ball 33 moves synchronously under the guidance of the first annular groove 15. The welding pen 34 can follow these two motion trajectories to achieve accurate and continuous weld positioning in three-dimensional space.

[0038] When the utility model is used in practice, the welded steel component is fixed on the welding plate 2105, and the first cylinder 13, the second cylinder 2203 and the second motor 2104 are started to set the position of the entire adjustment mechanism 2 so that it is suitable for the position of the welding part 3. During the welding process, the first motor 14 is started to move the welding part 3 along the path of the first annular groove 15. When it moves to the position to be welded, it stops and performs the welding operation.

Although the present invention has been disclosed as a preferred embodiment as above, it is not intended to limit the present invention. Any technical personnel in this field can make some changes or modify the technical contents disclosed above into equivalent embodiments without departing from the scope of the technical solution of the present invention.
