Embodiment
To describe technology contents of the present utility model, construction feature, the objects and the effects in detail, below in conjunction with implementation
Mode simultaneously coordinates accompanying drawing to be explained in detail.
Refer to the structural representation and figure of Fig. 2, the stationary jaw of scroll chuck and fixed pedestal；Fig. 3, scroll chuck
Stationary jaw and fixed pedestal structural representation；
A kind of scroll chuck of the utility model, including chuck 1, pedestal, clamping jaw and location-plate 4；
Three sensing central orbits of chuck 1 are provided with the chuck 1, the interorbital is each other in 120 ° of angle, institute
State and be provided with base stand location groove in the middle part of track；
The pedestal is arranged above the track, and the pedestal is slided along the track, and 2 are provided with the pedestal
Base stand location through hole, base stand location groove fixed pedestal on matching track position in orbit, in the present embodiment, with fixed
Position pin is positioned.In other embodiments, can also be positioned with taper bolt and alignment pin.
The clamping jaw is connected with the pedestal, and the clamping jaw includes a clamping table being directed upwards towards in clamping side
Face, for clamping article；
In the present embodiment, three pedestals are respectively two fixed bases, 21 and one movable base 22, and three clamping jaws are distinguished
For two stationary jaws 31 and a movable jaw 32, the both side surface of the clamping surface of stationary jaw 31 is provided with linker
The hole of seat, by bolt arrangement, pedestal is connected with clamping jaw.
Refer to Fig. 4, the movable jaw of scroll chuck and movable base side structure schematic diagram, Fig. 5, scroll chuck
The vertical section structure schematic diagram of movable jaw and movable base, Fig. 6, scroll chuck movable base structural representation.
Movable jaw 32 includes connecting portion 323 and clamping part 321, and the connecting portion 323 is connected with the movable base 22,
The clamping part 321 is arranged above the bare terminal end that clamping article is pointed on the movable base 22.
