[0008] Preferably, there are two positioning holes, and the central angle between the two positioning holes is the same as the central angle between the two fixing holes on the flange.

[0009] Preferably, the positioning hole is a threaded hole, which is used to position the flange by bolts.

[0010] Preferably, a chuck driven by a motor is also provided on the workbench, which is used to drive the oil pipe to rotate after the oil pipe is clamped by the chuck.

By arranging the support groove 41, the positioning groove 51 and the limiting groove 61 along the same straight line, the oil pipe 9 can be quickly limited and the oil pipe 9 can be kept vertical to the flange 8, which has the advantages of easy use, high welding efficiency and qualified rate.

[0029] In the limiting device for welding the oil pipe flange described in the utility model, if Figure 4 As shown, preferably, the bottom cross-sections of the supporting groove 41, the positioning groove 51 and the limiting groove 61 are all V-shaped, so that the oil pipe 9 can be better limited and kept vertical to avoid shaking.

[0030] In the limiting device for welding the oil pipe flange described in the utility model, if Figure 4-5 As shown, preferably, there are two positioning holes 52, and the central angle between the two positioning holes 52 is the same as the central angle between the two fixing holes 81 on the flange 8, and the specific central angle is 80°, so that not only the installation direction of the oil pipe 9 can be guaranteed, but also when the flange 8 is manually installed with the wrong hole position, the flange 8 cannot be installed on the positioning plate 5, thereby ensuring the accuracy of the installation.

[0031] In a specific embodiment, the positioning hole 52 is a threaded hole, which is used to position the flange 8 by bolts, thereby achieving detachable fixation of the flange 8, and further facilitating batch welding of the oil pipe 9 and the flange 8.

In a specific embodiment, the welding mechanism 7 is a welding robot or a welding gun. In actual application, after the welding robot or welding gun is installed on the slide rail at a set welding angle, the welding angle is kept unchanged. When spot welding or full welding is performed, it only needs to be translated along the slide rail.
