Technical Field

[0001] The utility model relates to the technical field of welding tooling, and particularly relates to an angle-adjustable welding turnover mechanism. Background Art

[0002] During the welding process of metal workpieces, in order to improve the welding quality and efficiency, various toolings are usually used to assist in positioning the workpieces for convenient operation. In the existing positioning devices, such as a welding device with auxiliary positioning disclosed in Patent CN220462689U, when in use, the first motor drives the worm gear to rotate, and then the bidirectional screw drives two driving blocks to move in opposite directions, and further drives the first clamping plate to fix or release the workpiece. By utilizing the self-locking characteristic of the worm and worm gear, the stability of the bidirectional screw is improved, so that the workpiece can be stably fixed.

[0003] Although the above device can fix the workpiece, during actual welding, the workpiece is not only welded on one surface. When welding another surface, the workpiece can only be removed, flipped and fixed again, which makes the workpiece positioning process cumbersome and inefficient, so there is room for improvement.

The first vertical plate is arranged on the base longitudinally, the first cylinder is arranged on the top of the first vertical plate longitudinally, the turnover assembly is arranged on the first vertical plate and is in transmission connection with the first cylinder. The turnover assembly includes a rotary cylinder, a double-headed cylinder and two clamping plates. The rotary cylinder is in transmission connection with the first cylinder through a sliding seat, the double-headed cylinder is arranged on the front side of the rotary cylinder in a transmission manner, and the two clamping plates are respectively arranged at both ends of the double-headed cylinder.

[0005] Further, a guide rod is arranged at each of the two ends on the front side of the first vertical plate, and the two guide rods respectively penetrate through both sides of the sliding seat. The first cylinder can drive the sliding seat to slide up and down along the guide rods.

[0006] Further, spring pins and knob-type bolts are arranged on the inner sides of the two clamping plates.
