[0025] The present invention will be further described below in conjunction with the accompanying drawings:

[0026] Example: Figure 1-Figure 4As shown, a workpiece clamp with a rotating function includes a mounting frame 101, on which a flip frame 102 and a flip motor 103 are arranged, the flip motor 103 is connected to the flip frame 102, and is used to drive the flip frame 102 to rotate, the flip frame 102 is provided with a rotating seat 107 and a rotating motor 106, the output end of the rotating motor 106 is connected to the input end of the rotating seat 107, the output end of the rotating seat 107 is provided with a fixed plate 108, a support seat 109 is arranged on the fixed plate 108, a fixed cylinder 110 is arranged on the fixed plate 108 on one side of the support seat 109, and a fixed pressure frame 118 is arranged at the output end of the fixed cylinder 110, and the fixed pressure is located above the support seat 109.

[0027] Specifically, the mounting frame 101 includes a base plate 121 and two side plates 120, the two side plates 120 are parallel to each other and are fixed on the same surface of the base plate 121, a transmission box 105 is fixedly arranged on one of the side plates 120, and a connecting seat 104 is arranged at a relative position of the other side plate 120, the flip frame 102 is located between the two side plates 120, and is connected to the connecting seat 104 and the output end of the transmission box 105, and the flip output end is connected to the input end of the transmission box 105.

[0028] A connecting frame 116 is provided at the output ends of the connecting seat 104 and the transmission box 105 , and the flip frame 102 is connected to the connecting seat 104 and the transmission box 105 respectively through the connecting frame 116 .

[0029] Specifically, a flip limiter 112 is fixedly provided on one of the side panels 120 , a flip limiter plate 113 is provided on the connecting frame 116 , and the flip limiter plate 113 and the flip limiter 112 cooperate with each other.

[0030] Specifically, a cushion block 117 is fixedly provided on the top of the support seat 109 by bolts, and a pressure block 111 is fixedly provided on the bottom of the fixed pressure frame 118 by bolts, and the cushion block 117 and the pressure block 111 are positioned opposite to each other.

[0031] The opposite surfaces of the cushion block 117 and the pressing block 111 are both provided with fixing grooves 119 , the cross section of the fixing grooves 119 is V-shaped, and the fixing grooves 119 on the cushion block 117 and the pressing block 111 extend in the same direction and are opposite in position.

[0032] Specifically, a rotation limiting piece 115 is disposed on the fixing plate 108 , and a rotation limiting device 114 is fixedly disposed on the flip frame 102 . The rotation limiting device 114 cooperates with the rotation limiting piece 115 .

[0033] The working process of this embodiment: the device is installed on the base of the argon arc welding machine, and cooperates with the argon arc welding machine to clamp and fix the workpiece to be welded.

[0034] When working, the gas source of the fixed cylinder 110 is connected, and the fixed cylinder 110 will extend after ventilation, driving the fixed pressure frame 118 to move upward, separating the pressure block 111 from the cushion block 117, and then aligning the workpiece to be welded and placing it between the cushion block 117 and the pressure block 111, and then the fixed cylinder 110 drives the fixed pressure frame 118 to move downward, clamping the workpiece to be welded between the cushion block 117 and the pressure block 111, and during welding, the transverse movement module 3 and the longitudinal movement module 4 and the lifting mechanism 5 will drive the welding mechanism 7 to move, and when the welding gun on the welding mechanism 7 moves to the top of the workpiece to be welded, the adjusting mechanism 6 will start working, driving the welding gun to move, and adjusting the gap between the welding gun and the workpiece to be welded according to the welding material and the welding process requirements. After the adjustment, the welding gun will be used to weld the workpiece to be welded. In the summary of the welding process, if it is necessary to adjust the welding direction of the workpiece to be welded, the rotating motor 106 or the flip motor 103 will start working.

[0035] When it is necessary to rotate the workpiece to be welded in the horizontal direction, the rotating motor 106 will start working, and drive the fixed plate 108 to rotate through the rotating seat 107. When the fixed plate 108 rotates, it will drive the workpiece to be welded to rotate in the horizontal direction through the support seat 109 and the fixed pressure frame 118, and when the rotating seat 107 drives the fixed plate 108 to rotate, the rotation limit plate 115 on the fixed plate 108 will also move. When the rotation limit plate 115 moves to the output end of the rotation limiter 114, the rotation limiter 114 will send a signal to the rotating motor 106 to stop the rotating motor 106 from rotating, so as to avoid damage to the equipment due to excessive rotation.

[0036] When it is necessary to adjust the inclination angle between the workpiece to be welded and the horizontal plane, the flip motor 103 will start working, and drive the flip frame 102 to rotate through the transmission box 105, so that the rotating seat 107 fixed on the flip frame 102 drives the fixed plate 108 to tilt, thereby realizing the adjustment of the inclination angle between the workpiece to be welded and the horizontal plane. Similarly, the flip frame 102 will drive the flip limit plate 113 to move when rotating. When the flip limit plate 113 moves to the output end of the flip limiter 112, the flip limiter 112 will send a signal to the flip motor 103 to stop the flip motor 103 from rotating, so as to avoid damage to the equipment due to over-limit flipping.

[0037] When the rotating motor 106 and the flipping motor 103 work simultaneously, the workpiece to be welded will be driven to rotate at multiple angles, and the workpiece to be welded can be automatically adjusted in multiple directions, thus avoiding the repeated disassembly and assembly process of the staff, reducing the labor intensity of the staff, and improving the welding efficiency.

[0038] The above is a detailed description of an embodiment of the present invention, but the content is only a preferred embodiment of the present invention and cannot be considered to limit the scope of implementation of the present invention. All equivalent changes and improvements made within the scope of the present invention should still fall within the scope of the patent coverage of the present invention.
