Then it could prompte to speed up the process of welding production of the various assistive devices and equipment. Welding fixtures also play an important role in Mechanized welding, with fixture, positioning quickly, easy clamping, effort, reduce the weldment assembly positioning and the clamping the heavy manual labor; flip the weldments can be mechanized, rapid deflection, and make the spatial location weld of poor conditions into a better position weld , improved working conditions, at the same time it help to improve the quality of the weld. When in the assembly weldments of positioning, if you do not use the fixture, even if the welding assembly formed by the two or three parts, to ensure the accuracy of the relative position of each part is very difficult. At the same time, in the welding process, the Welding parts generally would occurred welding deformation as uneven heating and other reasons, especially with the welded structures was complex, sometimes its deformation can not be eliminated, this will affect the future work of assembly. With fixture, not only can ensure the correct relative position in welding between the workpiece, but also can prevent and reduce the welding deformation of the workpiece. When in the mass production, this advantage become more apparent, can stabilize the quality of welded parts, reduce the production of defective. Welding roller standing by structural form is divided into two categories : the first category is long axis-wheel frame. the second category is modular roller frame. In this paper, twelve pairs of modular T-welded wheel for the design, as well as axial, bond and other main component of checking. The results showed that the main components to meet the requirements. The roller frame structure is simple, flexible, adaptive welded pieces of a strong, which is the most widely used form of the structure. And it could be fully considered the roller frame reasonable and economic, and other factors. Keyword: weld frock clamp turning rolls Signature 0f Supervisor：
