Specific embodiment
The utility model is described in detail with reference to the accompanying drawing:
Embodiment one:
As shown in Figure 1 to Figure 3, a kind of bellows tension and compression fixture, the entire pedestal 1 including rectangular groove profile, the bottom
The two sides of seat 1 are respectively equipped with clamping part 2, and clamping part 2 described in every side is equipped with interior jacking block 3 and outer fixture block 4, the end of bellows 9
Portion is held between the interior jacking block 3 of the same side and the outer fixture block 4, and in turn, the both ends of bellows 9 are held on two sides respectively
Between the clamping part 2, the clamping part 2 is equipped with adjusting connector, by the adjusting connector to the bellows 9
End is squeezed or is stretched.
Specifically, the adjusting connector includes the strut 5 being arranged on the clamping part 2, and one end of the strut 5 connects
It is connected to the interior jacking block 3, the other end of the strut 5 is revealed in outside the pedestal 1, is drawn by 5 power transmission of strut same
The interior jacking block 3 and outer fixture block 4 of side and then along compressing axially or stretch the bellows 9.
More preferably, the clamping part 2 is clamping plate.The pedestal 1, clamping plate, strut 5, interior jacking block 3 and outer fixture block 4
It is high temperature resistant material, thus make entire pedestal that there is heat-resisting quantity, it can be with resistance to 1000 DEG C of high temperature.
Multiple screw holes 6 are equipped with as shown in Figure 1, being spaced apart on the clamping part 2, the strut 5 is screwed together in the screw hole 6
On, and then by rotating 5 power transmission of strut to the interior jacking block 3.
As shown in figure 3, the interior jacking block 3 and the outer fixture block 4 are the clamping flange of mutual size fit, the interior top
