Specific embodiment
The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model
It clearly and completely describes, but does not constitute the limitation to scope of protection of the utility model.
As shown in Figure 1, 2, a kind of five axis inner support clamps, including from top to bottom sequentially connected elastic collet 1, upper bed-plate 2,
C axis rotation center 3, C shaft platform 4, C shaft flange bottom plate 5, lower bottom base 6, twin shaft adjustable cylinder 7 and limit base 10；Wherein, on
An axial space 8 is formed inside pedestal 2, C axis rotation center 3, C shaft platform 4, C shaft flange bottom plate 5 and lower bottom base 6；
It further include the connecting rod 9 being set in axial space 8, connector sleeve 11, camshaft bearing follower 12, connector 13；
Specifically, one end of connecting rod 9 is connect with twin shaft adjustable cylinder 7, the other end is connect with connector sleeve 11；Bearing follower 12 is arranged
In in connector sleeve 11 and stretching out connector sleeve 11 and connect with connector 13；It the other end of connector 13 and is set in elastic collet 1
