Description
Technical field
The utility model relates to the truing tool field of detecting device for determining torque of spanner, particularly a kind of force snesor standard torque spanner.
Background technology
Torque spanner is a kind of instrument being used for fastening bolt, is widely used in all conglomeraties, as torque spanner measurement verification utensil---detecting device for determining torque of spanner is also widely used accordingly.But the method that current most detecting device for determining torque of spanner still uses counterweight lever to hang carries out examining and determine and calibration operation, this method makes the calibrating of calibrating instrument and calibration operation bring inconvenience and measuring accuracy and stability are not high; Also have part detecting device for determining torque of spanner to use standard torquer to calibrate, but standard torquer is too expensive, equipment is too large simultaneously, and inconvenience is carried with, and calibration is inconvenient.
Utility model content
utility model object:for problems of the prior art, the utility model provides a kind of force snesor standard torque spanner, not only easy and simple to handle, precision and stability is high, and volume is little is easy to carry.
technical scheme:the utility model provides a kind of force snesor standard torque spanner, and one end of described moment of torsion plank is spanner body, and the other end is spanner, and the afterbody of spanner body is fixedly connected with the head of spanner; Described spanner body has the forcing shaft of brake block, force rod and force snesor by afterburning pedestal, end and forms; Wherein, described forcing shaft longitudinally runs through the inside be fixed near afterburning seat head, and brake block stretches out afterburning pedestal outside, force rod is fixed on the inside near afterburning pedestal afterbody, and described force rod effectively contacts with the head of spanner near the afterburning side of pedestal afterbody, for being delivered in the power that spanner applies; Described force snesor is fixed on the side near force rod on forcing shaft, and the force block on this force snesor effectively contacts with force rod, and the power be applied on spanner can be passed to force snesor by force rod by force block.
Preferably, described forcing shaft is fixed on the inside of close afterburning seat head by connection bearing.
Preferably, described connection bearing is air bearing or fluid bearing.
Preferably, described brake block is two, lays respectively at the two ends of described forcing shaft.
principle of work:when using the standard torque spanner in the utility model to calibrate tested detecting device for determining torque of spanner, first the brake block of standard torque spanner forcing shaft is inserted in the bolt hole of tested detecting device for determining torque of spanner, then spanner is pulled, spanner drives the afterburning pedestal be fixedly linked with it to rotate arbitrarily angled around forcing shaft, while pulling spanner, power on spanner can pass to force snesor by the force rod of effectively contact with it, this twisting resistance is exported to user by force snesor again, simultaneously the bolt hole of tested detecting device for determining torque of spanner also can rotate due to the drive of brake block, namely correspondingly a twisting resistance can also be measured, the absolute value of the difference of the twisting resistance of this twisting resistance and standard torque spanner is the error of tested detecting device for determining torque of spanner.
beneficial effect:the utility model volume is little, be easy to carry, simple to operate, and measuring accuracy is high, good stability.
Accompanying drawing explanation
Fig. 1 is the cross-sectional view of force snesor standard torque spanner in the utility model.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described in detail.
Be illustrated in figure 1 the sectional view of force snesor standard torque spanner in the utility model, as seen from the figure, the afterbody that this torque spanner forms spanner body 1 by spanner body 1 and spanner 2 two parts is substantially fixedly connected with the head of spanner 2, in order to better spanner 2 and spanner body 1 be fixed, can arrange groove at the afterbody of spanner body 1, the head intercalation of spanner 2 is fixed in this groove; The outside of spanner body 1 is afterburning pedestal 3, the inner hollow of this afterburning pedestal 3, longitudinally run through in the inside of close afterburning pedestal 3 head and be fixed with forcing shaft 5, in the present embodiment, this forcing shaft 5 can pass through connection bearing 8(air bearing or fluid bearing etc.) be fixedly connected with afterburning pedestal 3, to guarantee when afterburning pedestal 3 rotates, forcing shaft 5 also and then rotates, other link easily can certainly expected by those skilled in the art is fixedly connected with, and repeats no more herein; There is the brake block 4 in the bolt hole for inserting tested torque spanner the end of forcing shaft 5, this brake block 4 is positioned at one end of forcing shaft 5, and it is outside to stretch out afterburning pedestal 3, in present embodiment, also can respectively arrange a brake block 4 at the two ends of forcing shaft 5, one of them is as subsequent use because service time of a specified duration after, brake block 4 is abrasion deformation easily, and arranging an alternate brake block can effectively extend serviceable life of the present utility model; Also be provided with force rod 6 in the inside near afterburning pedestal 3 afterbody, and this force rod 6 preferably effectively contacts with the head of spanner 2, can the power transmitted delicately in spanner 2 be advisable; Force snesor 7 is fixed with near the side of force rod 6 in addition, the force snesor of this force snesor 7 preferred high accuracy, to guarantee to sense the size of the power be applied on spanner 1 by force rod 6 and the size of this power is exported to user at forcing shaft 5; This force snesor 7 is also fixedly connected with force block 9, this force block 9 is installed on force snesor 7 after can processing separately, also can directly and force snesor 7 one machine-shaping, for the power be applied on spanner 1 being passed to force snesor 7 by force rod 6.
When the utility model carries out calibration operation, first be that the brake block 4 on forcing shaft 5 is inserted in the bolt hole of tested detecting device for determining torque of spanner, then Twist wrench 2, spanner 2 drives afterburning pedestal 3 to rotate arbitrarily angled around forcing shaft 5, namely twisting resistance now on spanner 2 passes to force block 9 by force rod 6, twisting resistance is passed to force snesor 7 by force block 9 again, the size of this twisting resistance is exported to user by force snesor 7 again, meanwhile, due to the rotation of brake block 4, the bolt hole of detecting device for determining torque of spanner to be checked also can rotate, namely detecting device for determining torque of spanner to be checked also can measure a twisting resistance, the absolute value of the difference of the twisting resistance of this twisting resistance and standard torque spanner is the error of detecting device for determining torque of spanner to be checked, user completes the calibration of detecting device for determining torque of spanner to be checked according to this error.
Force snesor standard torque spanner structure in the utility model is simple, volume is little, easy to carry, simple to operate, be convenient to field calibration, and force snesor degree of accuracy is high, good stability, is convenient to the measuring accuracy and the stability that promote whole torque spanner.
Above-mentioned embodiment is only for illustrating technical conceive of the present utility model and feature; its object is to person skilled in the art can be understood content of the present utility model and implement according to this; protection domain of the present utility model can not be limited with this; all equivalent transformations of doing according to the utility model Spirit Essence or modification, all should be encompassed within protection domain of the present utility model.
