Support arrangement for camshaft VCT hole puncher

The utility model discloses a support arrangement for camshaft VCT hole puncher, it includes first supporting mechanism (3) and second supporting mechanism, first supporting mechanism (3) axle journal of connecting VCT hole one end on work bench (2) of puncher and on lieing in near camshaft (1) locate and compress tightly, the second supporting mechanism is installed on removal planker (6) of radial VCT hole perforating device on the puncher, and the backup pad when punching in the second supporting mechanism (5) one end upper surface offsets with the tip surface of camshaft (1) VCT hole department, is side surface and camshaft (1) of while backup pad (5) one end close to the wheel piece (1 in VCT hole 3 )The terminal surface offsets. After the structure, make the camshaft reduce the distance between the bite when the VCT hole of processing tip more than adopting, consequently the effort equilibrium, has reduced the camshaft and in the deformation that adds man -hour, has further guaranteed product quality in
