Electric force application device of torque coefficient comparator

Abstract

The present invention relates to a torque coefficient detecting device electric force applying device in the high-strength bolt torque coefficient detecting field, and the device comprises a fixed platform, an electric motor, a speed reducer, a connecting axle sleeve, a torque force applying square roller and a control switch, the output axis of the speed reducer is connected with the connecting axle sleeve with a dead key, the torque force applying square roller is installed in the connecting axle sleeve and can slide along the axis direction of the connecting axle sleeve in the connecting axle sleeve. The torque coefficient detecting device electric force applying device provided by the invention has a fixed installing position, in the using process the high-strength bolt torque coefficient detecting device can be excellent applied with force, at the same time the free advancing and retreating of the torque sensor which is affiliated with the detecting device in the detecting process is set aside with a space, the experiment requirement to various standard bolts is adapted thereby facilitating the more portability and flexibility of the operation. Besides, the invention realizes the uniform-speed load applying and accuracy control to the experiment torque and helps to increase the experiment precision; the experiment procedure can be completed with one man, the labor intensity is reduced greatly and the operating efficiency is increased.

Description

technical field [0001] The invention relates to the field of electromechanical equipment, in particular to high-strength bolt torque coefficient testing equipment. Background technique [0002] Torque coefficient verification is a routine test item for high-strength bolts. The torque coefficient of high-strength bolts can be obtained by recording the axial force and torque during the loading process. Existing torque coefficient calibration instruments usually use manual force application. For high-strength bolts with a diameter above M20, the loading torque is relatively large, and it is difficult to complete the calibration test alone. Especially for M27 and M30 bolts, the loading torque exceeds 1000Nm, and multiple people are required to cooperate. , the labor intensity is very high, and the efficiency is very low. In addition, a "constant torque electric wrench" currently on the market, because the output speed is too high, the required applied torque during the test is ...
