Types Of Fixture And Its Industrial Applications

Vise Fixture

It is simple to clamp workpiece along with regular shape and parallel sides in a vise. Therefore, workpieces with round or irregular shapes are extremely hard to clamp properly. Thus, special jaws are created to hold workpieces with irregular shape properly and at the similar time, it also prevents damage to the important surfaces. Several types of vise fixture are display in Figures that was given below (a), (b), (c), (d) and (e).

                                                     Figure :(a) : Vise Jaws

Figure (a) describes simple pair of jaws for holding round workpiece. Figure (b) describes pair of jaws for holding a thin sheet of non magnetic material. Stop pin is used to avoid bending of the workpiece through the application of clamping force.

                                                      Figure (b) : Vise Jaws

Extended jaws for huge workpieces are display in Figure (c). Here guide pins are used to secure alignment. When it is essential to hold the workpiece firmly in all the directions, wedge type jaws are useful. This arrangement is describe in Figure (d). If the pressure exerted through the cutting tool is likely to tilt upward one end of the workpiece, then the link construction as display in Figure (e) should be used. It is appropriate for rough casting and forging because it allows considerable variation in dimensions of workpiece
