Description
Technical Field
[0001] The utility model relates to the technical field of welding auxiliary equipment, and more specifically, to an adjustable roller bracket. Background Art
[0002] The roller frame is a device that uses the friction between the weldment and the active roller to drive the circular weldment to rotate in order to complete the welding of the annular weld. The welding speed can be adjusted by the speed of the active roller on the roller frame. The roller should always be kept on the same axis so that the workpiece is not easily deformed or slipped when rotating. Its core function is to allow the workpiece to rotate easily during the welding process, thereby achieving different welding positions and angles and ensuring the quality and uniformity of the weld.
[0003] When placing and supporting the workpiece, the existing bracket can only support and rotate the circular workpiece.

[0032] The tops of the two sliding frames 8 are fixedly connected with a first bearing 26, and a rotatable support column 27 is arranged in the first bearing 26. The top of the support column 27 is fixedly connected to the bottom of the bracket 9, and the support column 27 can drive the bracket 9 to rotate counterclockwise or clockwise. Through the first bearing 26 and the support column 27, it is convenient to adjust the angles of the two rollers 10 when placing a conical workpiece, so as to place the workpiece for welding. The roller 10 can rotate clockwise and counterclockwise to adjust the different placement directions of the conical workpiece.
[0033] Specifically, the outer surface of the support column 27 is fixedly connected to the first meshing gear 28, and one side of the sliding frame 8 is fixedly connected to the support plate 29. The top of the support plate 29 is fixedly connected to the telescopic frame 30 and the second bearing 32. The top of the telescopic frame 30 is fixedly connected to the insertion rod 31.

For some conical workpieces, the staff can pull the telescopic frame 30, push the rotating frame 33 to rotate in the second bearing 32, drive the second meshing gear 34 to rotate, drive the first meshing gear 28 to rotate, drive the support column 27 to rotate in the first bearing 26, adjust the angles of the two rollers 10, and thus place the workpiece for welding;
