Design And Development Of Semi Automatic Jig In Horn Assembly To Reduce Cycle Time

Abstract

Jig’s purpose involves providing accuracy, repeatability, and interchangeability in the manufacturing processes while machining.  Jig is a work-holding device that is utilized in holding, supporting, and locating the workpiece and guiding one or more tools to perform an intended operation. Generally, increasing productivity is one of the foremost goals among the manufacturing industries. Implementation of automation and techniques to increase the operators’ efficiency are some of the strategies adopted by the companies to achieve these goals. During the recent years, industries in developing countries like India, are adapting to the various types of automation systems. This study aims to improve the overall productivity in a horn manufacturing industry assembly line, by eliminating the bottle neck in the manufacturing process. In the Vibromini horn assembly line used in the industry, once the testing is over , the tuning pin marking and providing of the  thread locker are carried out manually , which cause a bottleneck in the whole operation, thereby decreasing the productivity. To overcome the above mentioned problems, an automated jig has been designed in this work, which reduces the overall cycle time of the operation. SOLIDWORKS 2014 software has been used to design the 3D model of the jig.
