Design for Manufacturing and Analysis of Motorized Bench Vice

Abstract - A vice is nothing but a holder which has two holding points at each ends and this holding points help the work piece to stay in place so that the work can be done on the work piece. Now here one of the jaws on the vice is fixed and do not move and the other jaw that is placed in opposite moves so that we can adjust the vise according to the work piece design. So basically the first jaw of the vice helps to hold the work piece in the place and the second jaw can be used to tighten or loosen according to the shape of the work piece. So this is how the basic bench vice works. So the vise can be used for doing many works on it such as to shape a metal object, to make keys, also to cut the object etc.. Like this there are many ways for which we can use the bench vise. Now the paper basically relates to the vises and the scope of improving the working of Bench vise with the help of using a DC motor which helps in the movement of the jaws through the dc motor. Now the main objective of this paper is to make a bench vise which can be operated without any man power and use dc Motor to clamp the work piece so that the work can be done on it. The power to the movable jaw is supplied by the dc motor so that the work can be done on the work piece of any size and shape. We have also tested the vise with various work Pieces just to verify so that it can hold properly while the work is done. Also contact stress analysis is studied at the contact of grip and work piece of diameter 10 mm at various loads such as 10N, 50 N and 100 N. Key Words: Design, Bench vice, Motorized, Contact stress
