The utility model is further set to: described straight-bar one end is provided with the mounting groove of placing dial gauge, and the both sides of described mounting groove are equipped with the fixedly gib screw of dial gauge.
By adopting technique scheme, if the damaged words of dial gauge, as long as adjust loose gib screw just can easily dial gauge have been taken out in mounting groove, by adjusting two gib screws, can realize the position of finely tuning dial gauge, higher to reach the precision of measurement.
The utility model is further set to: the other end of the relative dial gauge of described straight-bar is provided with illuminating torch.
By adopting technique scheme, in dark place, can conveniently see the reading on straight-bar clearly.
The utility model is further set to: the relative straight-bar of described fixed block one end is provided with rubber blanket.
By adopting technique scheme, when screwing wing nut, rubber blanket is fixedly close in ring plate, prevent from that fixed block from rotating ring plate is ground away or damage by pressure.
The utility model is further set to: described dial gauge comprises dial plate, measuring staff, measuring staff cover and measuring staff mobile division, and described measuring staff puts the lock-screw that is provided with locking measuring staff, and described measuring staff puts and is provided with corresponding threaded hole.
By adopting technique scheme, when fixing ring plate when wanting reading, can first screw lock-screw, prevent in reading, measuring instrument occurs to shake and causes reading out of true.
The utility model is further set to: described measuring staff outer end is the arc surface caving inward.
By adopting technique scheme, measuring staff outer end is the arc surface caving inward, and ring plate outer wall can be embedded in arc surface, and ring plate is stablized regularly more, measures more accurate.

Embodiment
Referring to figs. 1 through Fig. 3, the utility model ring plate concentricity measuring instrument embodiment is described further.
A kind of ring plate 12 concentricity measuring instruments, comprise straight-bar 1 and dial gauge 2, described straight-bar 1 is provided with the slippage groove 3 arranging along straight-bar 1 centerline direction, described dial gauge 2 is arranged on straight-bar 1 one end, in described slippage groove 3, be provided with slidably the stationary installation 4 of fixedly punching, described stationary installation 4 comprises wing nut 41, bolt 42 and fixed block 43, described bolt 42 is threaded with wing nut 41 through slippage groove 3 and fixed block 43 successively, described fixed block 43 is provided with corresponding through hole 44, and described straight-bar 1 is provided with scale 5.Described straight-bar 1 one end is provided with the mounting groove 6 of placing dial gauge 2, and the both sides of described mounting groove 6 are equipped with the fixedly gib screw 7 of dial gauge 2.The other end of described straight-bar 1 relative dial gauge 2 is provided with illuminating torch 8.Described fixing relative straight-bar 1 one end is provided with rubber blanket 9.Described dial gauge 2 comprises dial plate 21, measuring staff 22, measuring staff cover 23 and measuring staff mobile division 24, and described measuring staff cover 23 is provided with the lock-screw 10 of locking measuring staff 22, and described measuring staff cover 23 is provided with corresponding threaded hole.Described measuring staff 22 outer ends are the arc surface 11 caving inward.
