The body structure includes four important components: the device comprises a base 1, a floating platform 2, a telescopic device and a damping buffer mechanism; wherein, the floating platform 2 can be movably arranged on the base 1 up and down; the floating platform 2 is connected in the telescoping device drive, and the telescoping device is balance cylinder 5, and balance cylinder 5 communicates in the cylinder air-vent valve 6 of adjustable atmospheric pressure size. The floating platform 2 can be driven to approach and depart from a reference limit point 3 arranged below the floating platform 2; one end of the damping buffer mechanism is connected to the base 1, and the other end of the damping buffer mechanism is connected to the floating platform 2, so as to counteract the impact energy when the whole floating platform 2 is downward. Balance protection detection sensors 10 for detecting the position of the floating platform 2 are arranged on two sides of the floating platform 2. The core of the process structure is that adjustable spring force is flexibly applied to offset the self weight of the whole mechanism, and then an adjustable balance cylinder 5 is used for adjusting down pressure to ensure that the mechanism contacts a reference limit point 3. The cylinder force is finely adjusted to realize that when the product is assembled in error, the counterforce can be controlled so that the whole floating platform 2 is pushed away, the signal of the balance protection detection sensor is lost, and the assembly is stopped, so that the product is protected.
