Described scroll chuck is prior art, chuck body, movable jaw and claw driving mechanism, consists of.
Described chuck body is provided with protecgulum and bonnet, and connects as one by the bolt being located on lid.
On the protecgulum of described scroll chuck, be equidistantly provided with three chutes, claw moves radially along chute, and extends the length that claw makes progress at chuck axis, and the contact area of increase and cylinder body can improve fixing stability in centering fast.
The bonnet inner circumferential of described scroll chuck is provided with three bevel pinions, wire tray engagement in bevel pinion and chuck body, bevel pinion drives wire tray, there is archimedean spiral groove at the back side of wire tray, be meshed with 3 claws, with spanner, rotate little Zhui Chi Lun ﹐ and just can make 3 claws radially move, realize self-centering and clamping simultaneously.
Advantage of the present utility model:
1, compare electrical measuring method and flash spotting, have easy and simple to handlely, be not vulnerable to the feature of the impact (such as temperature, humidity) of external condition.
2, extend the length that claw makes progress at chuck axis, the contact area of increase and cylinder body, can improve fixing stability in centering fast, and this point is vital to measuring cylinder body radial strain.
3, the strain that foil gauge of electrical measuring method can only be measured certain some single direction, and this device can be realized the measurement to the whole circumferential strain of cylinder body by rotating circular disk.
4, this device is provided with T-shaped groove on rotating circular disk, slidable adjustment clock gauge by slide block is in the position of radial direction, and by adjusting bolt positioning sliding block, can realize the adjustment of clock gauge radial direction, meet the measurement requirement to the radial strain of different-diameter cylinder body, realized the versatility that cylinder body radial strain is measured.
