Abstract
Description
Technical Field
[0001] This utility model relates to the field of nut electrode welding, and in particular to a vertical welding electrode holder device. Background Technology
[0002] The welding principle is to melt the metal workpiece and form a connection by conducting current through electrodes. Generally, an upper electrode and a lower welding seat are set. During welding, the workpiece is placed on the lower welding seat and moved by the upper electrode, and the current is conducted between the upper electrode and the lower welding seat to achieve welding. Among the workpieces to be welded, many require the welding of nuts.
[0003] Welded nuts solve the problem of ordinary nuts failing to secure the base material. Furthermore, welded nuts offer superior strength and are easy to install, leading to their increasing use. Traditional vertical welding electrode devices (i.e., lower welding seats) use circular vertical electrodes that automatically move up and down for vertical welding. The hole orientation is generally horizontal, requiring perfect vertical alignment. When changing nuts for different workpieces, the lower welding seat must be adjusted for vertical alignment. If misaligned, the welding machine (upper electrode) moves downwards during welding, potentially causing the product to hit the upper electrode's handle joint, affecting the weld. This paper proposes a new vertical welding electrode holder device. This device uses a copper block paired with a set of linear vertical electrode holders to create a simple electrode assembly. During welding, this device is installed on the welding machine and the screws are tightened. Its position can be adjusted arbitrarily, improving the practicality of the welding device.
