Aim: Design a screw clamp for securing work to the table of a machine, such as shaper, planer. This case study analyses the steps to design a screw clamp with the given data.
Gap (centre of screw to inside of frame) = 16 cm
Distance between jaws = 22 cm
Parts to be designed for the screw clamp are as follows:
The exact compressive load on work depends upon the effort applied by a worker at the end of a handle and arm length of the handle. Screw should be designed on the basis of this effort and arm length of handle and practice of lengthening the handle temporarily by the use of a pipe is deplorable because it eventually bends the handle due to excessive bending moment on handle. The ...
