Description

Technical Field

[0001] This utility model belongs to the field of chain welding technology, specifically an automatic welding device for metal chain parts. Background Technology

[0002] In the metal chain manufacturing industry, welding, as a key process connecting each link of the chain, directly impacts product performance and production efficiency. Traditional chain welding relies heavily on manual operation, with welders using welding torches to weld each link one by one. However, this method has numerous drawbacks. On the one hand, the precision of manual welding depends entirely on the welder's experience, making it difficult to guarantee consistent weld quality. Defects such as uneven weld width, incomplete welds, and weld detachment frequently occur, resulting in significant variations in the overall strength of the chain and a defect rate as high as 15%-20%. On the other hand, manual operation is slow, severely limiting production capacity in the face of large-scale production demands. Furthermore, workers are exposed to high temperatures, strong light, and harmful gases for extended periods, which can damage their health.

[0003] With the accelerating pace of industrial automation, the development of automated welding equipment is urgently needed. While some rudimentary automated welding attempts exist, they suffer from numerous shortcomings. Existing equipment struggles to adapt to welding various chain specifications. Frequent changes of tooling and fixtures are necessary for chains with different pitches and link sizes, resulting in time-consuming and labor-intensive equipment changeovers accounting for 20%-30% of total production time. Furthermore, during welding, the equipment's positioning and clamping of chain links are unstable, leading to chain displacement under welding thermal stress. This can cause welding position deviations exceeding 0.5mm, severely impacting welding quality and chain safety. In addition, existing automated equipment lacks intelligent monitoring and feedback mechanisms, failing to adjust welding parameters in real-time to address changes in chain material and surface condition, further limiting weld quality improvement. Therefore, developing an automated welding device with high-precision positioning, adaptive welding parameter adjustment, and compatibility with various chain specifications is crucial to overcoming current production bottlenecks. Utility Model Content

[0004] The purpose of this invention is to solve the problems mentioned in the background.

[0005] To achieve the above objectives, the technical solution provided by this utility model is as follows: This utility model discloses an automatic welding device for metal chain parts, comprising a first track, a welding machine, and a positioning and moving assembly. The positioning and moving assembly intermittently pulls the metal chain, which is located within the first track. The welding machine welds the notches in the metal chain. The positioning and moving assembly includes a second track, a moving plate, a moving cylinder, a positioning cylinder, a positioning plate, and a positioning rod. The moving plate is mounted on the outer wall of the second track via a slide rail. The moving cylinder drives the moving plate to move along the slide rail. The positioning cylinder is mounted on the moving plate. One end of the positioning plate is rotatably connected to the moving plate, and the middle part is rotatably connected to the output shaft of the positioning rod. The positioning rod is mounted on the positioning plate.

[0006] Preferably, a crossbar is provided above the first track, with the end of the crossbar away from the second track bent upwards, and the crossbar presses against the metal chain.

[0007] Preferably, the welding machine is located between the first track and the second track.

[0008] Preferably, the crossbar is provided with a mounting base, the mounting base is provided with a positioning rod, the positioning rod is provided with a positioning sleeve, and a spring is provided between the positioning sleeve and the mounting base.

[0009] Preferably, the end of the second track away from the first track is provided with an arc-shaped plate, and the metal chain hangs down along the arc-shaped plate.

[0010] Compared with the prior art, the technical solution provided by this utility model has the following advantages: This utility model discloses an automatic welding device for metal chain parts. A movable cylinder drives a movable plate towards a first track. Then, the output shaft of a positioning cylinder extends, causing a positioning rod to rotate and engage with the chain hole of the metal chain. The welding machine then welds the metal chain. Afterward, the movable cylinder drives the movable plate away from the first track, meaning the positioning rod pulls the metal chain. The output shaft of the positioning cylinder retracts, disengaging the positioning rod from the metal chain. This process is repeated cyclically, allowing welding of each section of the metal chain. The entire device is stable, efficient, and highly automated. Attached Figure Description

The positioning and moving component 300 intermittently pulls a metal chain 400, which is located within the first track 100. The welding machine 200 welds the notches of the metal chain 400. The positioning and moving component 300 includes a second track 310, a moving plate 320, a moving cylinder 330, a positioning cylinder 340, a positioning plate 350, and a positioning rod 360. The moving plate 320 is mounted on the outer wall of the second track 310 via a slide rail. The moving cylinder 330 drives the moving plate 320 to move along the slide rail. The positioning cylinder 340 is mounted on the moving plate 320. One end of the positioning plate 350 is rotatably connected to the moving plate 320, and the middle part is rotatably connected to the output shaft of the positioning rod. The positioning rod 360 is mounted on the positioning plate 350.

[0020] In this embodiment, a crossbar 110 is provided above the first track 100. The end of the crossbar 110 away from the second track 310 is bent upward, and the crossbar 110 presses down on the metal chain 400.
