[0006] The positioning device includes a base plate, positioning pins, positioning columns, pre-positioning blocks, support columns, support blocks, compression springs, leveling screws, clamping blocks, cylinders, and mounting plates.

[0007] The locating pin is installed on the locating post using screws;

[0008] The positioning pins are mounted on the base plate with screws.

[0009] The pre-positioning block is mounted on the base plate via a support column and a height-equalizing screw passing through a compression spring.

[0012] The cylinder is mounted on the mounting plate with screws.

[0020] The floating device supports the floating base with two equal-height screws and two springs, enabling the entire device to float in both the up and down directions. The support base is supported by linear guide rails and springs on both sides, enabling the device to float left and right.

[0030] The threaded block is connected to the floating rotating body through its own steps, six sides, and a spring is placed between the threaded block and the rotating body to press the threaded block against the floating rotating body. The motor provides rotational torque, which is transmitted to the rotating body through the coupling, then to the floating rotating body through the equal height screw and spring, and then to the threaded block through the six sides of the floating rotating body and the spring. Thus, the torque is transmitted from the motor to the threaded block.
