The automatic welding workstation comprises an overturning positioner and a robot arm 4, wherein the overturning positioner comprises a machine table 1, a clamp module 2 and a conveying line 3, the clamp module 2 is rotatably arranged on the machine table 1, the clamp module 2 comprises two oppositely arranged clamping assemblies, the two clamping assemblies can be relatively close to or far away from each other, each clamping assembly comprises a base plate 211, a first positioning tool 212 and a second positioning tool 213, the first positioning tool 212 is fixedly arranged on the base plate 211, the first positioning tool 212 comprises a first positioning structure matched with a workpiece 9, the second positioning tool 213 is movably arranged on the base plate 211, the second positioning tool 213 comprises a second positioning structure matched with the workpiece 9, the conveying line 3 comprises a first transfer assembly 31, the first transfer assembly 31 is movably arranged on the machine table 1, and the first transfer assembly 31 can be relatively close to or far away from the clamp module 2, the robot hand 4 is provided with a welding gun, and the robot hand 4 is used for welding the workpiece 9.

In the conventional welding workstation, after the robot arm 4 completes welding one side surface of the workpiece 9, the orientation of the workpiece 9 needs to be manually adjusted to facilitate the robot arm 4 to weld the other side surfaces of the workpiece 9, which results in low automation degree of the welding workstation. The turnover positioner is workpiece 9 turnover equipment which can be used in various occasions, can clamp the workpiece 9 and then turn over to change the posture of the workpiece 9, and can automatically turn over the workpiece 9 by introducing the turnover positioner into a welding workstation, so that manual intervention is reduced, and the automation level of the welding workstation is improved.

However, the existing roll-over positioner still requires some manual intervention. Particularly, if the position is not right in the pendulum of work piece 9 when the material loading, for example work piece 9 skew or incline in preset position, will lead to the unable accurate centre gripping of upset machine of shifting, can lead to subsequent automatic weld process welding dislocation to appear, probably lead to the work piece 9 in the centre gripping to drop even, consequently need by artifical adjustment work piece 9 to suitable position and angle, the centre gripping is carried out again to the upset machine of shifting, the automation level of current upset machine of shifting remains to be improved.

According to the automatic welding workstation provided by the invention, the overturning positioner is provided with the first positioning tool 212 and the second positioning tool 213, when the automatic welding workstation is used, the workpiece 9 is pre-clamped by the first positioning tool 212, the position and the angle of the workpiece 9 are adjusted by the first positioning structure, and then the workpiece 9 is further clamped by the second positioning tool 213.

It can be understood that, adjusting the position of the workpiece 9 means that the two clamping assemblies move in opposite directions according to a set operation mode, the first positioning structures located on the two sides of the workpiece 9 clamp the workpiece 9, and position the workpiece 9 at a preset point, and adjusting the angle of the workpiece 9 means that if a certain deviation exists between the actual angle of the workpiece 9 and the ideal angle, the acting force of the first positioning structures can apply a certain torque to the workpiece 9, so that the angle of the workpiece 9 is adjusted. For example, as shown in fig. 3, two sides of the workpiece 9 are flat, and the first positioning structure includes a positioning plane adapted to the side of the workpiece 9, and if the side of the workpiece 9 is not parallel to the positioning plane, the positioning plane can apply a torque to the side to align the workpiece 9.
