That is, unless otherwise stated, each feature is only an example of a series of equivalent or similar features.

[0016] according to Figure 1 , 23, a piston ring assembly platform, comprising an assembly platform 1, on which an assembly device 2, a piston 3 and a piston ring 4 are arranged, the assembly device 2 comprises a frame 5, a piston ring opening device 6 and a control switch 7; the piston ring opening device 6 is arranged on the frame 5, and is used to open the piston ring 4 for easy installation on the piston 3, the piston ring opening device 6 is arranged to have a symmetrical structure, and the piston ring opening device 6 comprises two pairs of symmetrically arranged fixing rods 61, each pair of fixing rods 61 is provided with a hook piece 62, and the fixing rods 61 The fixing rod 61 is rotatably arranged on the frame body 5 via a pin shaft 64, and a connecting rod 63 is arranged at the bottom of the fixing rod 61, and the connecting rod 63 is rotatably arranged on the fixing rod 61 via a through shaft 65; the bottoms of all the connecting rods 63 are connected by a common through shaft 65; the frame body 5 is also provided with a replaceable arc groove 53, and the arc groove 53 is also provided with a plurality of piston ring grooves 54 for placing piston rings 4, and by replacing the arc groove 53, the position and number of the piston ring grooves 54 can be adjusted to adapt to pistons 3 of different specifications.

[0017] A telescopic cylinder 51 for pushing the piston ring opening device 6 is provided on one side of the frame body 5 to provide power for the piston ring opening device 6. The movable end of the telescopic cylinder 51 is passed through the frame body 5, and the movable end of the telescopic cylinder 51 is connected to the fixed rod 61 through a through shaft 65 at the connection between the connecting rod 63 and the connecting rod 63 via a connecting piece; a mounting plate 56 and a return spring 52 are provided on the other side of the frame body 5, one end of the return spring 52 is hooked on the mounting plate 56, and the other end is hooked on the through shaft 65 at the connection between the fixed rod 61 and the connecting rod 63. The telescopic cylinder 51 is connected to the control switch 7 for controlling the start of the telescopic cylinder 51.

[0018] The hook piece 62 is located at the bottom position of the arc groove 53 and corresponds to the piston ring groove 54 to facilitate the expansion of the piston ring 4. The frame body 5 is provided with a groove 55 for accommodating the through shaft 65 and facilitating the movement of the through shaft 65 at the position of the through shaft 65 at the connection between the fixing rod 61 and the connecting rod 63 and at the position of the through shaft 65 at the bottom of the connecting rod 63.

[0020] In practical application, firstly, different arc grooves 53 are set according to the specifications of the piston 3, and the piston ring 4 is placed in the piston ring groove 54 with its opening facing downwards. Then, the telescopic cylinder 51 is activated by operating the control switch 7, thereby promoting the operation of the piston ring opening device 2. During this process, the connection between the fixed rod 61 and the connecting rod 63 shrinks inwards, and the bottom of the connecting rod 63 moves downward, causing the hook piece 62 to flip outwards, thereby expanding the piston ring 4, and then the piston 3 is placed in the expanded piston ring 4; the control switch 7 is operated again to retract the telescopic cylinder 51, and under the action of the reset spring 52, the piston ring opening device 2 returns to the state before shrinkage, and the piston ring 4 is set on the piston 3.

It also ensures that the piston ring 4 can be correctly installed on the piston 3, reducing installation errors caused by inaccurate manual operation. The replaceable arc groove 53 improves the flexibility and applicability of the device.

[0022] The present invention is not limited to the above-mentioned specific implementation modes, but extends to any new features or any new combination disclosed in this specification, as well as any new method or process steps or any new combination disclosed.
