Description

Technical Field

[0001] This invention relates to the field of welding technology for the production of mechanical parts, specifically to a welding equipment for the production of mechanical parts. Background Technology

[0002] Ring welding is required in the production of mechanical parts. Ring welding usually refers to the welding of circumferential welds, such as flange butt joints and bushing connections, which require continuous welding at 360 degrees. The main function of welding equipment used in the production of mechanical parts is to ring weld mechanical parts to circumferential components, thereby improving the efficiency and quality of ring welding of mechanical parts.

[0003] Patent CN220388343U discloses a welding device for metal parts production, including a base. A welding machine is fixedly connected to the surface of the base via a bracket. A feeding mechanism is provided on the surface of the base, including an upper sliding plate and a lower sliding plate. This patent relates to the field of metal parts production technology. This welding device for metal parts production uses a transmission shaft to drive a transmission belt. The upper part of the transmission belt drives the upper sliding plate to move to the left, and the lower part of the transmission belt drives the lower sliding plate to move to the right. The upper sliding plate moves the welded metal parts to the left to the personnel position, and the lower sliding plate, through a lifting plate, moves the metal parts to be welded to the right to directly below the welding machine. This allows for the handling of metal parts at a dedicated manual workstation, making operation simple and convenient, and avoiding the high temperature at the welding machine location and the risk of burns from falling hot metal shavings.

[0004] However, the current welding equipment used in the production of metal parts has the following problems: during the process of welding mechanical parts, the welding torch of the welding equipment is very easy to bump into the surface of the mechanical parts, which leads to the bending and damage of the torch tip. Therefore, we propose a welding equipment for the production of mechanical parts. Summary of the Invention

The straight ring rod 145 drives the double rod frame 146 to move downward, and the double rod frame 146 drives the base plate 147 to move downward. During the downward movement, the base plate 147 supports the hose 143, preventing the connection between the hose 143 and the tank shell 142 from bending.
