Abstract
A stud driver and remover and a method of making the same overcomes the problems of the prior art and accommodates driving and removing of studs and subsequent removal of the studs from the stud driver and remover. The stud driver and remover constructed in accordance with the method of the present invention can drive and remove studs of any size without causing any significant damage to the stud, and the stud is subsequently easily removable from the stud driver and remover after a stud removal operation has been performed.
Claims3
A tool driven by a driving adapter for driving and removing a stud relative to a workpiece comprises:
- a main ring with an axial bore, one end of the bore being located adjacent the driving adapter and the opposite end being located proximate a stud;
- a core member mounted within the bore of the main ring for limited axial and rotary movement relative to the main ring, said core member including a plurality of roll slots;
- a plurality of rolls carried by the corresponding roll slots of the core member;
- and
- a plurality of recess areas located adjacent each corresponding one of said roll slots for accommodating a deformed, wave-shaped portion of said stud formable when said stud is being removed from said workpiece.
A tool driven by a driving adapter is formed by a method comprising the steps of:
- providing a main ring with an inner diameter determined in accordance with the size of the stud to be driven and removed by the tool;
- forming an axial bore in the main ring such that one end of the bore is located adjacent to the driving adapter and the opposite end is located proximate the stud to be removed;
- mounting a core member within the bore for limited axial and rotary movement relative to the main ring;
- providing the core member with a plurality of roll slots for accommodating a predetermined number of roll according to the diameter of the stud to be removed;
- placing a roll within each of the corresponding roll slots;
- and
- forming a relief area adjacent each of said roll slots for accommodating a wave-shaped deformity of the stud formable when the stud is being removed.
