Automatic Centre Punch

A remodeling - as accurately as possible - of a centre punch with a compression spring loaded automatic function. A tool with a simple, interesting and effective mechanism. Notes: All threads are modeled with theoretical values of M10,5 and a pitch of 1 mm. Any clearance between bolt and nut is non-existent. The neutral lenght of the compression springs are: 38 mm for the action spring 21 mm for the conical wounded spring Try to understand why this center punch can works properly. I hope, that my model can show the function in a way without an animation. If anybody is able to animate my model in a self-explanatory way, please try it out. I'm not able to do such a complex animation by myself. A lot of thanks thanks would be sure. The model is available in following data formats: STEP-file (.stp) of the complete assembly and all native files (.prt) and (.asm), together in a (.zip)-folder, for users of »PTC Creo Parametric 2.0«
