HACKSAW USING ADJUSTABLE STROKE MECHANISM

Abstract

Normally hacksaw operation uses cam and lever mechanism. In this mechanism, the stroke length of the hacksaw can not be adjusted. In this project we use an adjustable stroke mechanism in which the stroke length can be adjusted for adjusting the stroke length of the hacksaw. This consists of two cam wheels, levers, hacksaw, vice etc. The two cam wheels are fixed with frames. The connecting rods of the two cam wheels are connected with a tilting lever so that when the two cams are rotated, the tilting frame will be moving up and down with respect to its center. The hacksaw is connected with the center rod of the tilting lever. The center rod moves up and down through a guide. A single gear motor operates the two cam to rotate in same direction. When the gear motor is switched on, the cams operate the center rod to move up and down. The position of the two cams can be adjusted to adjust the stroke length of the hacksaw. A vice is connected to hold the work piece. To get maximum efficiency, we can adjust the stroke length to maximum.
