Vertical multi-claw welding machine

Abstract

The invention relates to welding devices, in particular to a vertical multi-claw welding machine. The vertical multi-claw welding machine comprises a frame, a first power member, a second power member, a third power member, a spindle, a hollow shaft, a worm wheel, a parallelogram link mechanism, welding torches, a rotating plate and an intermittent feeding unit. The first power member drives the spindle to move downwards to firmly fix a workpiece by being matched with a fixing member and a clamping groove. The second power member transmits the workpiece to the hollow shaft, a worm and the worm wheel sequentially, so that the parallelogram link mechanism swings to adjust the distance between the welding torches and portions to be welded, of a steel cylinder. The third power member drives a second bevel gear to move downwards at the same time. A first bevel gear performs circumferential rotational displacement and then drives a plurality of welding torches to rotate circumferentially and move a certain distance, the welding of a section of the circumferential portion to be welded, of the steel cylinder is completed at one time, and the intermittent feeding unit drives the rotating plate to rotate intermittently to feed, so that automatic feeding and one-time welding are achieved actually. The vertical multi-claw welding machine is high in working efficiency, safe, reliable and easy to operate.

Description

technical field [0001] The invention relates to the field of welding, in particular to a vertical multi-claw welding machine. Background technique [0002] Cylinder welding is still at the level of manual arc welding, and the requirements for operators are quite strict. Not only is the labor intensity high, the working environment is harsh, the cost is high, and the efficiency is low, but also the welding quality is not easy to guarantee under the condition of mass production, which is far from Can not meet the needs of modern industrial development. [0003] For example, CN 203409411 U discloses an automatic welding device for the base of a steel cylinder shield, which includes a workbench, a gas shielded welding torch, a fine-tuning handwheel, an air cylinder and a stepping motor. Into the motor and the cylinder, and the middle of the workbench is provided with a gas-shielded welding torch and a fine-tuning handwheel, and the gas-shielded welding torch is connected with t...

Problems solved by technology

However, this welding device can only fine-tune the gas-shielded welding torch, and the adjustment range is small, which has certain limitations; at the same time, the gas-shielded welding torch needs to be welded evenly and intermittently for many times before the welding can be completed, and the work efficiency is low.
