The probe in hole, dial gauge protrudes out to the intracavitary and lower end with bolt in hole against the central spindle and spiral shell of probe from the lower aperture of threaded hole
The hole core of keyhole is arranged in parallel.
It is a further object to provide a kind of measurement methods of above-mentioned measuring device, comprising the following steps:
S1: dial gauge is installed to after fixing seat in integral installation to the lower disk of mounting disc again, steel wheel is placed on peace
On sabot upper disk surface, and the bolt hole of steel wheel is aligned with threaded hole；
S2: being inserted into bolt hole by bolt and with the torque of the prefastened torque size of the bolt tighten bolt, and at this time hundred
The reading for dividing table is N1；
S3: bolt is tightened with the torque of the Tightening moment size of the bolt, the reading of dial gauge is at this time, then by bolt
Unscrew；
S4: tightening bolt with the torque of the prefastened torque size of the bolt again, and the reading of dial gauge is N3 at this time；
N3-N1: just being obtained the expendable deflection of steel wheel bolt hole periphery plate by S5, and thus deflection judges
The rigidity of bolt hole.
In above scheme, a dial gauge is dexterously fixed below mounting disc, can be convenient by the reading of dial gauge,
Accurately read the rigidity deflection of bolt hole.
Detailed description of the invention
Fig. 1, Fig. 2 are operation schematic diagram of the present invention；
Fig. 3 is the structural schematic diagram of dial gauge and fixing seat；
Fig. 4 is the structure chart of mounting disc.
Specific embodiment
Rigidity refers to the ability that material or structure resist flexible deformation in stress, is material or structural elasticity deformation difficulty or ease
The characterization of degree is to measure to resist elastic deformation amount in stress so wanting the rigidity of measurement steel wheel bolt hole.
A kind of steel wheel bolt hole stiffness measurement device is provided with the mounting disc 20 for placing steel wheel A on pedestal 10,
It is provided with threaded hole 21 corresponding with steel wheel A upper bolt hole C in mounting disc 20, the probe 31 of dial gauge 30 is from threaded hole 21
Lower aperture protrudes out to the intracavitary and lower end with bolt B in hole against the central spindle of probe 31 and the hole core of bolt hole C are arranged in parallel.This
A pointer dial gauge 30 is cleverly fixed in invention below mounting disc 20, and position is located at the underface of bolt hole C, bolt
It corrects under it when B locks steel wheel and is contacted with the probe 31 of dial gauge 30, and have suitable decrement；By test determination
When torque tightens wheel bolt B, with the Light deformation of steel wheel bolt hole C, wheel bolt B generates downward displacement, due to
Bolt B lower end and 30 probe 31 are contacts, therefore the small deflection can pass through the hand motion of dial gauge 30
It accurately shows, accurately reads bolt hole C rigidity deflection so as to convenient.
In order to which dial gauge 30 to be fixedly connected with mounting disc 20, dial gauge 30 is fixedly connected with fixing seat 40, and described consolidates
Reservation 40 includes chassis 41, and the first mounting hole 411 connecting with the lower disk of mounting disc 20 is provided on the outer ring of 41 disk of chassis,
The lower disk middle part position on chassis 41 has extended downwardly connecting column 42, and both perforations are offered on connecting column 42 and chassis 41
Through-hole 43, probe 31 pass through from through-hole 43 and protrude from the upper disk surface on chassis 41.Dial gauge 30 is first installed to fixing seat 40
On, then fixing seat 40 is connected in mounting disc 20 again,
Further, locking hole 421 is also provided on the outer wall of connecting column 42, clamping screw 422 passes through locking hole 421
Afterwards with 32 outer wall of probe pillar in through-hole 43 against and lock the position of dial gauge 30.Between dial gauge 30 and fixing seat 40
Be also it is demountable, dial gauge 30 can be moved in axial position, make the lower end of its probe 31 and bolt B against.
The outer ring of the mounting disc 20 is provided with the second mounting hole 22 for connecting with pedestal 10, and threaded hole 21 is arranged interior
On circle.
The reading stayed alone on dial gauge 30 for convenience, the region between two columns of pedestal 10 constitute observed reading area.
The measurement method of the measuring device, comprising the following steps:
S1: dial gauge 30 is installed to after fixing seat 40 in integral installation to the lower disk of mounting disc 20 again, steel wheel A is put
It sets on 20 upper disk surface of mounting disc, and the bolt hole C of steel wheel A is aligned with threaded hole 21；
S2: bolt B is inserted into bolt hole C and tightens bolt B with the torque of the prefastened torque size of the bolt B, this
When dial gauge 30 reading be N1；
S3: tightening bolt B with the torque of the Tightening moment size of the bolt B, and the reading of dial gauge 30 is N2 at this time, so
Bolt B is unscrewed afterwards；
S4: tightening bolt B with the torque of the prefastened torque size of the bolt B again, and the reading of dial gauge 30 is N3 at this time；
N3-N1: just being obtained the expendable deflection of steel wheel bolt hole periphery plate by S5, and thus deflection judges
The rigidity of bolt hole.
The torque table that the prefastened torque and Tightening moment look into bolt obtains.There is the bolt B of different model in table
Corresponding prefastened torque and Tightening moment, as long as we table look-up.
