[0034] In this embodiment, Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, a support rod 61 is fixed to the side wall of the support plate 5, a third motor 62 is fixed to the end of the support rod 61, a rotating shaft 63 is fixed to the output end of the third motor 62, a worm 64 is fixedly sleeved on the outside of the rotating shaft 63, a worm wheel 65 is meshed on the top of the worm 64, a support shaft 66 is fixed in the middle of the worm wheel 65, a driving gear 67 is fixedly sleeved on the outside of the support shaft 66, and a driven gear 68 is meshed on the top of the driving gear 67.

[0035] It should be noted that one end of the base 1 is fixedly connected to the mounting plate 4, and the other end of the base 1 is provided with a slide, which drives the other end clamping piece to clamp the pipe fitting 11 to move horizontally. Since the two ends are clamped synchronously, one end can be slidably set, which belongs to the prior art in this field. Its positioning only includes but is not the main innovation. Therefore, the sliding support plate 5 at the other end is not elaborated in detail in this article.

[0036] In this embodiment, Figure 1, Figure 2 , Figure 3 and Figure 4 As shown, the support shaft 66 is rotatably connected to the support plate 5 , and the driven gear 68 is fixedly connected to the rotating rod 6 .

[0038] It should be noted that the two ends of the rotating rod 8 are fixedly sleeved with threaded sleeves 94, and the rotating rod 8 is placed in the support plate 92 for rotation. The rotating rod 8 is driven to rotate by the screw 22, and the threaded sleeves 94 sleeved at both ends of its outer side rotate immediately, and the clamping rods 9 sleeved at both ends slide horizontally inward or outward at the same time and then fit against the outside of the pipe fitting 11 to clamp and fix it.

[0039] It should be noted that the specific models and specifications of the first motor 21, the second motor 26 and the third motor 62 need to be selected and determined according to the actual specifications of the device, and the specific selection calculation method adopts the existing technology in the field, so it is not repeated here.

[0040] The use method and advantages of the utility model: When the flip angle adjustment device of the visual system welding robot is working, the working process is as follows:

[0041] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, firstly, the two welded pipe fittings 11 are clamped, and the rocker 93 is manually rotated to drive the rotating rod 8 to rotate. When the rotating rod 8 rotates, the threaded sleeves 94 at both ends of the rotating rod 8 rotate accordingly, and the clamping rods 9 sleeved on the outside of the two threaded sleeves 94 slide horizontally at the same time, and the clamping rods 9 slide along the guide rods 91, so that the two clamping rods 9 are attached to the two ends of the clamping rods 9 to clamp and fix them, so that the pipe fittings 11 can be clamped firmly and not easy to shake, thereby improving the stability of welding;

[0042] Then, the welding robot body 3 is adjusted according to the required welding position, and the first motor 21 is started to drive the screw rod 22 to rotate. When the screw rod 22 rotates, the slider 23 connected to the outside immediately drives the slide seat 2 installed on the top through the slide plate 24 to adjust the horizontal direction in the lateral direction. The second motor 26 is started to drive the screw rod 27 to rotate. When the screw rod 27 rotates, the external slide seat 2 immediately slides along the groove 25 on the top of the slide plate 24, so that it can be adjusted in the longitudinal horizontal direction, so that the welding robot can be adjusted according to the position of the pipe 11 required for welding, thereby improving the flexibility of welding;

[0043] When the pipe 11 is turned over after welding on one side, the third motor 62 is started to drive the rotating shaft 63 to rotate. When the rotating shaft 63 rotates, the worm 64 on the outside rotates and meshes with the worm gear 65. The worm gear 65 rotates under the force and drives the middle support shaft 66 to rotate around the support plate 5. When the support shaft 66 rotates, the external driving gear 67 rotates and meshes with the upper driven gear 68. The driven gear 68 drives the rotating rod 6 to rotate under the force, so that the pipe 11 clamped at the end of the rotating rod 6 rotates and flips, which makes it easier to turn over and weld the pipe 11, thereby improving the welding efficiency.

[0044] The above shows and describes the basic principle, main features and advantages of the utility model. Technical staff in this industry should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only preferred examples of the utility model and are not used to limit the utility model.
