Depending on their application, the fixture is needed in different industries. The locating pin is used to restrict the panel's degree of freedom. The panel will affect the loading and unloading of the panel due to a fixed position pin, so we have to configure the shift tool to change the positioning pin during loading and unloading of the panel. In this project we will create a CAD model with a jig and welding fixture. The change unit or the position unit will be designed as compact as possible, depending on the need for the jig and the welding fixture. This project is designed to move the positioning pin between the locating pin and the panel to avoid interference during loading and unloading.

Thus jigs and fixtures are used and are one of the most critical installations of the mass production system. These are special work holding and tool guiding device. The output quality of a process primarily determined by the quality of the jigs and fittings used for this purpose. What makes a fixture special is that everyone is designed to match a particular part or shape. A fixture has the main function of locating and retaining a work piece during service. In addition to locating and supporting the work piece, a jig differs from a fixture in the sense that it directs the tool to its correct location or movement during operation. Fixture required Specialization to accurately hold the work-piece during the welding operation. The Fixture designed hold job and rotate the job at required Speed. The reduced cycle time and operator labor while increasing functionality [1],[2], [3]. Depending on their application, the fixture is needed in different industries. Due to some drawbacks the configuration of a new fixture is changed over the current fixture. The part fixture is installed manually so loading and unloading of the material take more cycle time [4] , [5], [6], [7]. . Work-holding methods have also changed considerably; the core principles of clamping and position are still identical. Mass production methods require a simple and easy way to put work on them for various operations. To address this issue we designed the welding fixture with enhanced mobility [8], [9], [10], [11]. In general, clamping is necessary to hold the job in the jig. Much as in the automotive market, jigs may also be concept guides or templates. Special cramping jigs to ensure that the panel is placed in the right position. The fixture is a strong and rigid mechanical device that attaches to a machine and allows the stock to slide while holding firmly, allowing for simple, easy and reliable accuracy of position, support, and clamping. A fixture is a device for locating, holding, and supporting a work- piece during a manufacturing operation. This consists of locators, clamps, supports, and fixture body [12], [13], [14], [15]. The unit's contents describe jigs and fixtures as a work piece clamping device and guiding device for the
