Description
Technical field
The utility model relates to the calibration technology of dial torque wrench, particularly relates to a kind of charger of dial torque wrench verification.
Background technology
Dial torque wrench also is torque spanner or torque spanner; When threaded fasteners such as holding screw bolt and nut, need control the moment size that applies; Destroy screw thread to guarantee screw threads for fastening and to be unlikely to because of moment is excessive, so need to adopt the dial torque wrench of preset nominal torque value to operate.Commercially available dial torque wrench mainly contains sound equipment mechanical type, dial type and digital display type dial torque wrench etc. at present.
With sound equipment mechanical type dial torque wrench is example; Pre-set needed upper torque limit value; Work as the upper limit that the moment of torsion that applies reaches setting during use; Spanner promptly can send the sound of " Ka Takata " or in the certain angle of spanner junction bending, show that the moment that applies arrives the upper limit, and bolt is fastened not to have needed reinforcing again.
The precision of dial type dial torque wrench is higher, and good stability is applicable to the torgue measurement of accurate demanding securing member, can left-handedly operate, and measuring accuracy is ± 3%.But general engage sleeves barrel spanner sleeve supplies the measurement of fastening hexagon head bolt, nut to use, and when tightening, can express torque value.Every moment of torsion to bolt, nut has the clearly assembly work of regulation, and the cylinder assembling like automobile, tractor etc. all will be suitable for this type spanner.
The digital display type dial torque wrench has adopted microelectric technique; Through the high precision torsion torque sensor measurement data is accurately shown; Its stable performance, power consumption are low, simple to operate, are specially adapted to the bolted and the control of industries such as automobile, motorcycle, machine-building.
General dial torque wrench all need carry out the moment of torsion verification, usually use one section day after date must verification once, some factory must carry out verification earlier before requiring to begin every day to produce.Otherwise the moment of torsion exact value will reduce.The moment of torsion tester generally is on an operating platform, to be provided with a moment of torsion charger, can be provided with the geometrical clamp that is used for fixing pinch bar at the opposite side of operator's console.When needing the torque spanner of verification different size; Sensor on the moment of torsion charger must change the specification of the correspondence that meets the moment scope into; Could normally use; Thereby during the dial torque wrench of repeated examinations different stage, must change the torque sensor of different size repeatedly, make the actual particularly big operation quantitative change of operation get very time-consuming and inconvenient.
Therefore, a kind of novel moment of torsion verification loading tool need be provided really, can simply save time by handled easily, increase work efficiency.
Summary of the invention
The purpose of the utility model is to provide a kind of moment of torsion verification charger of torque sensor on same operating platform of compound different size; The dial torque wrench of different nominal torque values all can be loaded and verification on a moment of torsion verification charger; Thereby convenient large batch of operation provides work efficiency.
Be to realize above-mentioned purpose, the utility model provides a kind of dial torque wrench verification charger, comprises a torsion load operation platform, is arranged on the moving guide rail of operator's console one side, the spanner fixed station and the industrial computer that can move along guide rail.On said operator's console, be provided with the moment of torsion charger of three different torque measurement scopes, wherein each moment of torsion charger include the base that is fixedly installed in above the operator's console platform, be fixedly installed in the worm gearing below the platform, corresponding torque sensor and manually or motor driver.Advantageously, said spanner fixed station comprise base, be arranged in the base corresponding to the guide-track groove of guide rail, fixedly be erected in the fixed mount on the base and be used for the bolt that base and guide rail is fixing.Fixed mount is provided with height-adjustable cross bar.The top of fixed mount is provided with pivotable pin.
The beneficial effect of the utility model is; Dial torque wrench for different nominal torque values; Need not change torque sensor, just can on same operating platform, match suitable torsion charger and carry out manual or electronic loading; Thereby can carry out large batch of verification operation easily, increase work efficiency.
