The electric transmission system includes a motor, a worm gear reducer, a ball screw pair, and a bearing. The device is used to realize the rapid positioning and installation of the thrust-torque dual-component sensor on the calibration device.

[0025] Six lifting cylinders 2 are arranged below the mobile platform frame 1, and the mobile platform frame 1 is connected to the mobile trolley plate 5 through the linear guide rail 3, and the mobile trolley plate 5 is connected to the electric transmission system 4. The motor in the electric transmission system 4 is driven by the worm gear reducer to connect the ball screw pair, and the nut seat of the ball screw pair is fixedly connected to the mobile trolley plate 5. The moving position of the mobile trolley plate 5 on the linear guide rail 3 is accurately controlled by the electric transmission system.

[0026] A positioning rod 8 for positioning with the moving trolley plate 5 is provided on the lower connecting plate 7 , and the lower connecting plate 7 has a “cross” boss that docks with the lower rotating pressure plate 11 .

[0027] The upper connecting plate 6 has a "cross" boss that docks with the upper rotating pressure plate 10, and the upper connecting plate 6 is fixed to the top of the sensor 13 to be measured by a fastener 12.

[0029] like Figures 2 to 5 As shown, the present invention provides a method for installing a thrust-torque dual-component sensor quick positioning installation mechanism, the steps of which are:

[0030] Step 1: The six lifting cylinders are raised to the highest position, and the mobile trolley plate is moved to the far left under the action of the electric transmission system. The lower connecting plate is placed on the mobile trolley plate, and the two positioning rods on the lower connecting plate are positioned with the mobile trolley plate.

[0031] Step 2: Use a mobile or fixed crane to place the sensor under test on the lower connection plate, position the sensor through the inner positioning pin or outer positioning ring, and fix it with fasteners (such as screws, etc.). Then fix the upper connection plate to the top of the sensor under test, also with fasteners.

[0032] Step 3: Move the mobile trolley plate into the axial thrust-torque composite calibration standard device through the electric transmission system, so that the lower connecting plate is located directly above the lower rotating pressure plate, and then drop the 6 lifting cylinders to separate the lower connecting plate from the mobile trolley plate. The "cross" boss of the lower connecting plate is aligned with the "cross" groove of the lower rotating pressure plate and falls into the groove.
