Abstract

The invention provides an adjustable torque verification anti-torsion device. The device comprises a fixed shell, inner sliding blocks, an adjusting rod and anti-torsion rods; a sliding groove is formed in the fixed shell; an opening is formed in the surface of the fixed shell; adjusting rod insertion openings are formed in the two ends of the fixed shell; the inner sliding blocks are tightly embedded into the sliding groove; the anti-torsion rods penetrates through the opening to be connected with the inner sliding blocks; the anti-torsion rods move in the opening along with the inner sliding blocks; the adjusting rod penetrates through the adjusting rod inserting openings to be connected with the inner sliding blocks; and the adjusting rod is used for adjusting the position of the inner sliding blocks. The distance between the anti-torsion rods can be adjusted, so that the device can adapt to verification of electric tools of different sizes; the clamping height of an electric wrench can be adjusted, manual holding is not needed in the verification process; the attaching effect of the electric wrench is good through the inner side arc face of a tool supporting plate, so that the working condition that the wrench inclines by a small angle can be satisfied. The whole structure of the device is convenient to install and high in practicability. And the stability of the device can be effectively improved when the wrench is calibrated, and the calibration precision is improved.

Description

technical field [0001] The invention relates to the technical field of maintenance equipment, in particular to an adjustable torque calibration anti-torsion device. Background technique [0002] At present, there are many types of equipment for high-torque electric tool booster arms in the assembly process of bullet trains, locomotives, and vehicles, mainly including cantilever booster arms, carbon fiber rod booster arms, and rectangular tube booster arms. Due to the large operating torque of the electric torque tool, the operating object is fixed during operation, but during calibration, our mobile calibration vehicle is not suitable for fixing. In order to make the calibration equipment more stable, it is necessary to design an anti- The torsional device counteracts the reaction force during power tool calibration through internal force. At present, the existing calibration anti-torque devices are mainly fixed. [0003] At present, the calibration of high-torque power to...
