Specific embodiment
The present invention is further described below in conjunction with the accompanying drawings；
In the accompanying drawings：A kind of image instrument workpiece swelling fixed mechanism, including bottom plate 1 and the air inlet being connected on bottom plate 1
Pipe structure 2；Further include swelling knot being connected on bottom plate 1 and being connected with air feeder structure 2, for workpiece pressing 101
Structure；The expanding structure includes determining core housing 3, is movably connected in the mandrel 4 determined in core housing 3 and is connected to and determines outside core
The expansion compressing member 5 for workpiece pressing 101 between set 3 and mandrel 4；The expansion compressing member 5, which is arranged on, determines core housing 3
In the outer circle of mandrel 4；In actual use, it is fixed on the table by bottom plate 1,101 one end of workpiece is placed on swollen
Swollen compressing member 5 is determined on core housing 3 and mandrel 4, enters gas by air feeder structure 2 so that mandrel 4 is under by gas urges
It moves, with determining 3 collective effect of core housing, extrusion expansion compressing member 5 so that expansion compressing member 5 expands outward, so as to withstand on workpiece
On 101 inner wall, swelling workpiece 101 is achieved the purpose that；Not only pressing force is big, good reliability, and occupies little space, energy
The clamping of special-shaped workpiece is enough adapted to, use scope is wide.
In Fig. 1, Fig. 2：It is additionally provided with being connected with air feeder structure 2 on the bottom plate 1 and matches with expanding structure
Close the guiding-positioning structure 103 of positioning workpiece 101；In actual use, 101 one end of workpiece is pressed on expanding structure, another
End is conducive to accurately measure the size of aperture 102 by the support positioning of guiding-positioning structure 103.
In Fig. 1：The axis pin 6 for determining to be additionally provided on core housing 3 with the kidney slot 3-1 cooperations on mandrel 4；Control
Displacement distance of the mandrel 4 on core housing 3 is determined, and with connection guiding role, better reliability.
In Fig. 1：The outer circle for determining core housing 3 is ladder-type structure, is connected including small axis 3-2 and by bolt
The big axis 3-3 being connected on bottom plate 1；Workpiece 101 is smoothly sleeved on small axis 3-2, and the following table face paste of workpiece 101
It closes on big axis 3-3, positioning is more convenient.
