Detailed description of the invention
Describe an embodiment of the present utility model in detail below in conjunction with accompanying drawing.
The utility model embodiment is taking assembling front sliding column spring as example, and as shown in Figure 1 and Figure 2, the utility model comprises that countertorque spanner 1, the accessory 2 of measurement moment of torsion, numeral show torque wrench 3; On the accessory 2 of measurement moment of torsion, there is slotted hole; The accessory 2 of measuring moment of torsion is connected with digital display torque spaner 4; Countertorque spanner 1 has termination, location, and detected nut fastener 6 has locating hole 6a; Examined product comprises detected nut 4, spring 5, detected nut fastener 6, pallet 7, traveller cylinder 8; Detected nut fastener 6 is shock absorber piston rod; Component after the accessory 2 of measuring moment of torsion is connected with digital display torque spaner 4 is enclosed within on detected nut 3; In the slotted hole of the termination, location of countertorque spanner 1 from the accessory 2 of measurement moment of torsion, the locating hole 6a that connects detected nut fastener 6 is installed; Countertorque spanner 1 is spacing to detected nut fastener 6,10 ° of left and right of accessory angle of uniform rotation digital display torque spaner and measurement moment of torsion, read moment of torsion and detect the numerical value that spanner produces, can complete detected nut 3 screw-down torques of built-in outer moving tightening way and measure.
Operation principle:
In the time detecting the moment of torsion of nut 3, if adopt common mode, digital display torque spaner 3 links together with the accessory 2 of measuring moment of torsion, component after digital display torque spaner 3 is connected with the accessory 2 of measuring moment of torsion is enclosed within on detected nut 4, at the uniform velocity promote digital display torque spaner 3 and the accessory 2 component 10 degree left and right of measuring moment of torsion, because shock absorber piston rod 6 can rotate in a circumferential direction, the moment of torsion testing result obtaining is the comprehensive moment of friction producing between spring 5, shock absorber piston rod 6, pallet 7, traveller cylinder 8.To be a wrong result by what obtain,
Correct detection method is, digital display torque spaner 4 and the accessory 2 of measuring moment of torsion are linked together, component after digital display torque spaner 3 is connected with the accessory 2 of measuring moment of torsion is enclosed within on nut 3, countertorque spanner 1 is fixed on the locating hole 6a of detected nut fastener 6, detected nut fastener 6 shock absorber piston rods can not be rotated, the 10 ° of left and right of component angle that at the uniform velocity promote the accessory 2 of digital display torque spaner 3 and measurement moment of torsion, will obtain a correct torque value like this.
