[0032] The pin shaft 2034 is sleeved with a pin sleeve.
[0033] The outer ring frame 202 is provided with a protective cover 8 at the upper end of the inner ring frame 201 .
[0034] In a specific implementation, the two ends of the frame platform 10 are respectively fixed on two fixing frames 2011, the upper surface of the fixing frames 2011 is a plane, and the fixing frames 2011 and the frame platform 10 can be fixed by bolts; then the workpiece is transported to the frame platform 10, and then the workpiece is fixed, and the welding robot welds the weld on the front of the workpiece;
[0035] After the front welding is completed, the main motor 2031 in the driving structure 203 is started, and the main motor 2031 drives the driving wheel 2033 to rotate. The driving wheel 2033 moves the pin shaft 2034 to drive the inner ring frame 201 to rotate. The pin shaft 2034 is provided with a pin sleeve to reduce the friction and wear of the pin shaft 2034.

[0036] After that, the welding robot is in place to weld the weld after adjusting the angle; a shield 8 is set on the upper end of the inner ring frame 201 to protect the structure inside the inner ring frame 201 during the welding process to prevent welding slag from splashing into the inner ring frame 201;
[0037] The rotating mechanism 20 drives the workpiece to rotate gradually. After the rotating mechanism 20 rotates 180°, the back of the workpiece faces upward; the welding robot welds the weld on the back; after welding is completed, the rotating mechanism 20 returns to the initial position, and then transports the welded workpiece to the next workstation; the unwelded workpiece is transported to the frame platform 10, and the above operation is repeated.
[0038] The utility model drives the workpiece to rotate by the rotating mechanism 20, thereby realizing welding of the workpiece at multiple angles and multiple positions, solving the overhead welding problem of large frames and large steel structures, changing overhead welding to flat welding or horizontal welding, avoiding various problems caused by overhead welding, and improving welding quality and level.

[0040] In one embodiment, reference Figure 5 The above-mentioned clamping mechanism 40 includes multiple No. 2 cylinders 401; the multiple No. 2 cylinders 401 are respectively installed on both sides of the frame platform 10 through the fixed seat 402; the output end of the above-mentioned No. 2 cylinder 401 is connected with a connecting rod mechanism 403; the upper end of the above-mentioned fixed seat 402 is rotatably connected with a pressure arm 404, and the other end of the above-mentioned pressure arm 404 is connected with the other end of the above-mentioned connecting rod mechanism 403.
[0041] In a specific implementation, the conveying mechanism may be composed of a driving motor, a conveying wheel and a belt; one end of the workpiece is placed on the conveying wheel at one end of the frame platform 10; then the driving motor is started to drive the conveying wheel to rotate, and the conveying wheel drives the belt to rotate, thereby driving the entire conveying wheel group to rotate; the conveying wheel group drives the workpiece to move as a whole to the frame platform 10, and when the workpiece moves to the specified position, the second cylinder 401 starts to extend and drives the connecting rod mechanism 403 to drive the pressing arm 404 to press the workpiece, and after the workpiece is pressed and fixed, the workpiece is welded and rotated to adjust the angle for welding;
[0042] After the workpiece is rotated 180° to the back for welding, if part of the weld is blocked by the frame platform 10, after the rotating mechanism 20 drives the workpiece back to the initial state, the second cylinder 401 contracts to drive the pressing arm 404 to leave the workpiece, and the conveying mechanism continues to drive the workpiece to move, so that the blocked weld moves to an unblocked position; then the rotation continues to be performed to weld the unwelded weld;
[0043] Considering the distribution of the product's welds, the workpiece can also be welded by duplicating multiple workstations, and the welds at each workstation can be sequenced. Sequential welding is conducive to avoiding equipment fixtures and ensures the reliability of welding. Each workstation welds a certain amount of welds to ensure the overall welding rhythm, improves the accessibility and welding rate of product welds, and meets production needs.
[0044] Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
