Abstract
The theme of this design is the sliding clamp C-arm spot welding process equipment design, which this article is focused on the design of milling out the left side of the fixture outlet of plete set of programs. General steps: familiar with the functions of resistance welding and the use of forceps, and the assembly through visits to enhance the physical understanding of their application; in accordance with sliding arm parts diagram to determine the size of blank; process of the selected benchmark; machine tool equipment and
the choice of technique and equipment; processing margin; process of determining the size and tolerance; cutting; the calculation of the time fixed; dedicated fixture design program to identify areas such as described, and ultimately be a plete design.
Keywords: Spot welding tongs; slide arm;Technology tooling;fixture design; process.
