Nut automatic projection welding device

Abstract

The invention discloses a nut automatic projection welding device which comprises a nut conveyor, a projection welding machine, two lifting mechanisms, a servo mechanism and four work fixtures. The nut conveyor is arranged at the side surface of the projection welding machine, the servo mechanism is supported by bases and connected with guide rails of the two lifting mechanisms, and the servo mechanism is provided with two slide brackets connected with the lifting mechanisms correspondingly. The four work fixtures are divided into two sets. The two sets of work fixtures are mounted on the twolifting mechanisms correspondingly, and fixedly connected with the lifting mechanisms.

Description

technical field [0001] The invention relates to the field of welding technology, in particular to an automatic projection welding machine for nuts. Background technique [0002] Nut welding is a common operation in the industry. The traditional nut welding process is to place nuts manually, which will not only lead to low efficiency in the production process, but also cause safety accidents due to manual placement. Therefore, the nut welding production process Automation is especially important. The current automatic projection welding machine for nuts can be divided into single-station and multi-station, and the multi-station uses a rotating disc to feed materials, but this automatic projection welding machine for nuts is mostly suitable for welding small workpieces. When welding is required in the production process When the workpiece is large, there is only one station of the general projection welding machine, and the workpiece needs to be manually put in for welding, a...

[0002] Nut welding is a common operation in the industry. The traditional nut welding process is to place nuts manually, which will not only lead to low efficiency in the production process, but also cause safety accidents due to manual placement. Therefore, the nut welding production process Automation is especially important

The current automatic projection welding machine for nuts can be divided into single-station and multi-station, and the multi-station uses a rotating disc to feed materials, but this automatic projection welding machine for nuts is mostly suitable for welding small workpieces. When welding is required in the production process When the workpiece is large, there is only one station of the general projection welding machine, and the workpiece needs to be manually put in for welding, and then manually taken out after welding, because the holes on the workpiece must be aligned with the positioning pins when the workpiece is put in, so in this way It takes a long time to feed and discharge the material, which causes the work of the nut automatic projection welding machine to stop and reduces the production efficiency
