Abstract

The utility model discloses a torque spanner calibrator, comprising a supporting boosting mechanism, a part of measurement display, and a self-checking basic member, wherein, the supporting boosting mechanism (4) comprises an eccentric (9) with handle and a shaft center (10), the part of measurement display comprises a digital display (6) and a torque sensor (5), and the self-checking basic member comprises a standard cross beam (15), a tray (17) and weights (16).

Description

Torque spanner calibrator
A kind of tester that is used for the various torque spanneres of verification.
The utility model relates to the detection or the calibration of the instrument that is used to measure torque.
The assembling of mechanical fastener, the assembling of the part of particularly ensuring public security, often the moment of torsion to being applied has strict requirement.When adopting various torque spanner operation,, just must be termly himself precision be detected or verification in order to guarantee assembly quality.This verification work generally is to adopt the way of hanging counterweight, and also available sometimes torque spanner is examined mutually.This dual mode, both heavy original, out of true is dangerous again.Now occurred pointer tester, with screw pair reinforcing and mechanical sensor, its shortcoming is that precision is not high, and instrument itself can not self check.
The purpose of this utility model just is to provide a kind of simple, quick, accurate torque spanner tester, not only verification torque spanner easily, and instrument self check easily itself.
The formation of this tester can be illustrated in conjunction with the accompanying drawings.
The description of the drawings:
Fig. 1 is the structural representation of this torque spanner tester.
Fig. 2 is the detail of construction at sensor 5 tops among Fig. 1.
Fig. 3 is with the self-correcting standard and is installed graph of a relation mutually by this torque spanner tester.
As seen, except that the self-correcting standard, this torque spanner tester mainly comprises two parts.First is the afterburning part of supporting, be made up of monitor station 1, bearing 3 and guide rail 2 thereof, boosting mechanism 4 is housed on bearing 3 simultaneously, it comprises the eccentric wheel 9 and the axle center mechanism 10 of a band handle, unclamp axle center 10, eccentric wheel can slide in the T type groove of bearing 3 end faces.Second portion is made up of torque sensor 5 and digital moment of torsion display 6 for measuring the display part, joins with output line 8 therebetween.Be provided with zeroing, maximal value maintenance and reset circuit in the device for digit-displaying 6.
During verification, be contained on the sensor 5 by the stiff end of detrwisting torque wrench, the other end (shake and defend) rides on the bearing 3.Adjust boosting mechanism 4, the outer rim of its eccentric wheel 9 is contacted with spanner, turning handle can be realized reinforcing, reads torque value simultaneously on digital display meter 6, thereby the scale on the contrast torque spanner carries out necessary check adjustment.
For the ease of when placing tested torque spanner 7 selected one suitable be convenient to afterburning position, rotating spanner 7 repeatedly often.For this reason, on torque sensor 5, be provided with the ratchet device of forming by intermediate shaft 11 and ratchet 12, ratchet 13 and retracing spring 14.
In addition, for the ease of just on monitor station 1, tester being carried out self check, at sensor upper supporting plate 18 and lower carrier plate 19 are housed for 5 times, the two is hinged each other, be in during the verification spanner and overlap the position, and when self-correcting, be turned into 90 ° mutually, thereby make the axis of the sensor 5 that is fixed on the upper supporting plate 18 keep being parallel position with the table top of monitor station 1.At this moment, borrow key to hang on the sensor 5 on the standard crossbeam in the self-correcting standard 15, pallet 17 and standard test weight 16 hang over the two ends of crossbeam 15.
The measuring accuracy of this instrument is in ± 0.5%, and sweep velocity reaches 1000 times/second, and digital display is directly perceived also can be kept, stable accuracy, and good reproducibility, the verification torque range can be unrestricted.
Most preferred embodiment of the present utility model is promptly as above-mentioned.

Claims (3)

1, a kind of torque spanner tester, form by monitor station 1, bearing 3 and guide rail 2 thereof, it is characterized in that, described tester also comprises boosting mechanism 4, torque sensor 5 and digital display meter 6, described boosting mechanism 4 is contained in eccentric wheel 9 and axle center 10 thereof on the bearing 3, the band handle by a cunning and constitutes, be loaded on the top of sensor 5 by the stiff end of detrwisting torque wrench 7, the other end is taken to be placed on the bearing 3 and with the outer rim of described eccentric wheel 9 and is contacted, and sensor 5 borrows output line 8 and digital display meter 6 to link.
2, torque spanner tester according to claim 1, it is characterized in that, torque sensor 5 wherein be by intermediate shaft 11 and be sleeved on above it ratchet 12 with joined by detrwisting torque wrench 7, ratchet 13 and retracing spring 14 also are housed between described ratchet 12 and the described intermediate shaft 11.
3, torque spanner tester according to claim 2, it is characterized in that, described tester also has self checking standard standard crossbeam 15, standard test weight 16 and pallet 17, also be equipped with between sensor 5 and the monitor station 1 simultaneously can overturn mutually 90 °, hinged upper supporting plate 18 and lower carrier plate 19 each other.
