[0018] The base 10 includes a bottom plate 11, a plurality of foot pads 12 arranged at the bottom of the bottom plate 10, and two handles 13 respectively arranged at the top of the bottom plate 11. The bottom plate 11 is a rectangular plate-shaped structure for carrying the above-mentioned functional modules. There are four foot pads 12 distributed in a rectangular shape at the four corners of the bottom plate 11 and located on the side of the bottom 11 away from the handle 13, so that the base 10 has strong stability when placed and used. The handles 13 are arranged at both ends of the top of the bottom plate 11, so as to facilitate the user to carry the entire device.

[0019] The pressure ring assembly 20 includes a linear drive assembly 21 vertically arranged on the top of the base 11, a slide rail assembly 22 arranged on the top of the base 11, a rotational drive assembly 23 arranged on one side of the slide rail assembly 22, a mounting platform assembly 24 arranged on the rotational drive assembly, and a connecting rod group 25 arranged between the rotational drive assembly 23 and the mounting platform assembly 24.

[0020] The linear drive assembly 21 is a cylinder or a hydraulic cylinder. The slide rail assembly 22 includes a slide rail assembly 221 and a slider 222 disposed on one side of the slide rail assembly 221. The slider 222 is connected to the driving end of the linear drive assembly 21.

[0021] The rotary drive assembly 23 is a rotary cylinder. The rotary drive assembly 23 is controlled to rotate 180°, so as to realize the function of flipping the mounting platform assembly 24. When in use, after the sealing ring 40 is installed on the mounting platform assembly 14, the rotary drive assembly 23 will control the mounting platform assembly 14 to flip, so as to turn the sealing ring 40 to the bottom of the mounting platform assembly 24, so as to facilitate subsequent installation; after the sealing ring 40 is installed, the rotary drive assembly 23 will control the mounting platform assembly 14 to rotate back, so as to facilitate the installation of the next sealing ring 40.

[0022] The mounting platform assembly 24 includes a mounting platform body 241 , a convex ring 242 disposed on one side of the mounting platform body 241 , and a plurality of telescopic column assemblies 243 inserted into the mounting platform body 241 and tightly attached to the convex ring 242 .

[0023] The telescopic column assemblies 243 are arranged along the convex ring 242, and each of the convex rings 242 is provided with a telescopic column assembly 242 at the turning point of the outer contour. When the operator puts a sealing ring 40 on the outside of the telescopic parts 2434 described below of all the telescopic column assemblies 242, the outer contour shape of the sealing ring 40 is the same as the outer contour shape of the convex ring 242.

[0024] The telescopic column assembly 243 includes a positioning seat 2431, a positioning hole 2432 opened on the positioning seat 2431, an insertion hole 2433 opened on the mounting platform body 241, a telescopic member 2434 movably inserted in the positioning hole 2432 and with its end located in the insertion hole 2433, and a spring 2435 arranged between the telescopic member 2434 and the positioning seat 2431.

[0025] The positioning seat 2431 is disposed on a side of the mounting platform body 241 away from the convex ring 242. The positioning hole 2432 and the insertion hole 2433 correspond in position.

[0026] The telescopic member 2434 includes a base 2436 located in the positioning hole 2432, and an end 2437 disposed at one end of the base 2436. The base 2436 and the end 2437 are both cylindrical. The diameter of the base 2436 is greater than the diameter of the end 2437, and the diameter of the end 2437 is the same as the inner diameter of the insertion hole 2433.

[0027] The spring 2435 is used to control the extension length of the telescopic member 2434. When the spring 2435 is in a natural state, the telescopic member 2434 passes through the mounting platform body 241; when the spring 2435 is in a compressed state, the end of the telescopic member 2434 is flush with the side of the mounting platform body 241 where the convex ring 242 is provided.

[0028] The connecting rod assembly 25 includes a mounting plate 251 disposed on the end surface of the rotation driving assembly 23 , and two connecting rods 252 respectively disposed perpendicularly on the end surfaces of the mounting plate 251 .

[0029] The card holder 30 includes a plurality of surrounding positioning blocks 31. In this embodiment, the number of the positioning blocks 31 is four and they are distributed in a rectangular shape.

[0030] When in use, the operator first places the workpiece in the holder 30, and sets a sealing ring on the outside of the telescopic column assembly 243, and then the operator starts the device. After the rotary drive assembly 23 rotates 180°, the linear drive assembly 21 controls the mounting platform body 241 to approach the workpiece. The shape and position of the sealing ring 40 on the telescopic column assembly 243 are respectively the same as the shape and position of the mounting groove on the workpiece. When the mounting platform body 241 approaches the workpiece, the workpiece will contact and abut against the end face of the telescopic member 2434, so that the telescopic member 2434 retracts into the positioning hole 2432. Since the convex ring 242 is provided on the mounting platform body 241, when the end face of the telescopic member 2434 shrinks to be flush with the convex ring 242, the sealing ring 40 has been placed in the mounting groove on the workpiece, and at this time, the sealing ring is disengaged from the end of the telescopic member 2434, realizing the automatic installation of the sealing ring.
