盤２２により自動的に行われるようになっている。Next, the operation of the gas injection device having the above configuration will be briefly described. First, attach the non-threaded part 3 of the seal ring nut 3 to the outer cylinder 2.
The gas-filled shock absorber 1 (the shock absorber that is about to be filled with gas) into which the parts a are fitted is set on the shock absorber lifting platform 10j that has been lowered to the lower part of the pace section 101, and then raised. After that, when the movable frame 10C is lowered by the unit C movement mechanism 11, the lower end of the boot 13 is moved to the inclined surface 19 of the stopper 18.
The diameter of the opening 1 is reduced by the inclined surface 19.
The inner circumferential surface of 4 is in close contact with the outer circumferential surface of the outer tube 2 to seal the space between the socket portion 7 of the unit body 9 and the outer tube 2. Therefore, if nitrogen gas or the like is injected into the socket part 7 from the gas inlet 15, the gas in the core socket part 7 will be introduced into the outer cylinder 2 through the gap between the seal ring nut 3 and the outer cylinder 2. Ru. Next, when the nut driving mechanism 12 drives the nut operating body 6 (up and down movement and rotation), the wrench portion 4 of the nut operating body 6 automatically fits into the packing land portion 3C, and the seal ring nut 3 By screwing into the outer cylinder 2, the gas is sealed inside the outer cylinder 2. Once the gas is sealed inside the outer cylinder 2, first move the nut operating body 6 upward using the nut drive mechanism 12, and then return the movable frame 10a to its original position using the unit drive mechanism 11 to begin the gas injection operation. The goal is to complete the process. In addition, the gas-separated human-operated shock absorber 1 is replaced with the shock absorber lifting platform 1.
The work other than setting it in the predetermined position of 0j- is automatically performed by the control panel 22.
