Design and Standardization of Scissor Jack to Avoid Field Failure

Mechanical Engineering

On road emergency, i.e. tire gets punctured, is a common problem observed in automobile and also it is big headache to driver. Scissor or toggle jacks are one of the best option to overcome this headache. Scissor jack is used to lift the heavy loads in which rotary motion is converted into linear motion. In this Paper, a unique design of scissor jack is compile to lift low as well as heavy load with different conditions. The main purpose and significance of this paper is to design, optimize and standardize the current toggle jack to make the task easier and reliable. Catia is used to develop and analyzed the scissor jack. Mathematical model of design procedure is also made which will suppose to help in standardization of scissor jack design by using MATLAB. The design calculation includes design of Power Screw, Link design, Design of Nut, Pin Design etc. All products from engineering should be versatile with application by maintaining its aesthetics and ergonomics. This paper mainly focused on designing and standardization of scissor jack model of automobile L.M.V. sector and trying for weight reduction of scissor jack with good strength. Also some changes are done in design procedure so that it will be useful for different models of L.M.V. in automobile industry. Car jacks are available in the market has some disadvantages such as required more energy to operate, are not suitable for woman and cannot be used on the uneven surface. So that, this design is modified for the existing car jacks in terms of its functionality and human factor consideration.
