The working principle of the clamp capable of changing the included angle provided by the utility model is as follows:
when the cylinder driving device connected between the cylinder 23 and one of the clamping base plates 3 drives the piston rod 52 to extend, because the second hinge 24 and the first pin 244 cannot move relative to the cylinder 23, the first hinge 53 can only rotate relative to the second hinge 24 via the first pin 244, the fourth hinge 31 and the second pin 311 cannot move relative to the clamping base plate 3, the third hinge 54 can only rotate relative to the fourth hinge 31 via the second pin 311, and the clamping base plate 3 can only rotate relative to the cylinder 23 via the hinge 6, under the driving of the cylinder driving device, corresponding to the extension movement of the piston rod 52, at this time, the first hinge 53 rotates relative to the second hinge 24 via the first pin 244 in a direction away from the other clamping base plate 3 (i.e. when the piston rod 52 extends relative to the cylinder of the cylinder driving device, the cylinder driving device rotates relative to the cylinder 23 in a direction away from the other clamping base plate 3), meanwhile, the third hinge 54 rotates in a direction away from the clamping base plate 3 relative to the fourth hinge 31 through the second pin 311 (that is, when the piston rod 52 extends relative to the cylinder of the cylinder driving device, the cylinder driving device rotates relative to the clamping base plate 3), and the clamping base plate 3 rotates in a direction away from another clamping base plate 3 relative to the cylinder 23 through the hinge 6, so that an included angle between the clamping base plate 3 and another clamping base plate 3 gradually increases along with the extension of the piston rod 52. Similarly, when the cylinder 23 and one of the clamping bottom plates 3 are connected by the cylinder driving device to drive the piston rod 52 thereof to extend, the included angle between the other clamping bottom plate 3 and the clamping bottom plate 3 is also gradually increased along with the extension of the piston rod 52 thereof, so as to match the model of the welding part such as the tuyere stock with a larger included angle (e.g. 90 degrees).
Similarly, when one cylinder driving device connected between the cylinder 23 and one of the clamping bottom plates 3 drives the piston rod 52 to shorten, corresponding to the contraction movement of the piston rod 52, at this time, the first hinge member 53 rotates in the direction approaching the other clamping bottom plate 3 relative to the second hinge member 24 through the first pin 244 (i.e., when the piston rod 52 contracts relative to the cylinder of the cylinder driving device, the cylinder driving device rotates in the direction approaching the other clamping bottom plate 3 relative to the cylinder 23), and at the same time, the third hinge member 54 rotates in the direction approaching the clamping bottom plate 3 relative to the fourth hinge member 31 through the second pin 311 (i.e., when the piston rod 52 contracts relative to the cylinder of the cylinder driving device, the cylinder driving device rotates relatively approaching the clamping bottom plate 3), and the clamping bottom plate 3 rotates in the direction approaching the other clamping bottom plate 3 relative to the cylinder 23 through the hinge 6, so that the included angle between the clamping base plate 3 and the other clamping base plate 3 is gradually reduced along with the contraction of the piston rod 52 to match the type of the smaller included angle (such as 45 degrees) of the weldment such as the tuyere stock.
As another embodiment (not shown in the drawings), the connecting shaft 22 includes: a pair of rotating shafts which are respectively and correspondingly connected to the pair of supporting frames 21 in a rotatable manner, and a pair of clamping bottom plates 3 are respectively and correspondingly connected to the pair of rotating shafts; in a preferred embodiment, the pair of rotating shafts are provided to face each other. And the rotation driving device is used for driving the rotating shaft to drive the clamping bottom plate 3 to rotate.

In a preferred embodiment, the rotation driving device is an electric motor or a hydraulic motor, the main body of the rotation driving device is mounted on the support frame 21, and the output shaft of the rotation driving device is connected to the rotating shaft.
In this embodiment, the holding member 4 includes: the clamping head 41 is arranged at the top end of the clamping bottom plate 3 and used for clamping the tuyere bent pipe; the chuck 41 includes: a plurality of groups of clamping jaws 411 arranged at even intervals; the diameter of the circumcircle of the clamping jaw 411 is smaller than the inner diameter of the tuyere elbow, and the tuyere elbow is clamped and clamped on the clamping jaw 411 by sleeving at least one end of the tuyere elbow to clamp and fix the tuyere elbow.

As a preferred embodiment, the connecting shaft 22 can rotate on the bearing seat 25, and as an implementation mode, the connecting shaft 22 is directly driven to rotate by an output shaft of the motor; as another embodiment, the output shaft of the motor drives the connecting shaft 22 to rotate through a gear train of the gearbox or a synchronous pulley mechanism; the positions and angles of the pair of clamping bottom plates 3 relative to the connecting seat 2 and the base 1 as a whole are changed, so that the tuyere bent pipe clamped on the clamping assembly 4 is in positions and angles relative to the converter of the connecting seat 2 and the base 1, and the welding seam 71 between the segmented pipe bodies needing to be welded by the tuyere bent pipe is adjusted to be matched with the welding bead of the welding gun.
