[0033] A detection mechanism is used to detect whether the sealing ring is installed in place;

[0034] In the present embodiment, both the assembly mechanism and the sealing ring bringing mechanism need to be installed in a fixed position when working. In the present embodiment, the first mounting plate 1 and the second mounting plate 2 are respectively used as reference objects for the fixed position. The positional relationship between the first mounting plate 1 and the second mounting plate 2 is a vertical relationship. Therefore, the coordinate system can be set with the first mounting plate 1 and the second mounting plate 2 as reference objects to specifically explain the working state and principle of the present application. Taking the first mounting plate 1 as the coordinate system, vertical movement is movement in the Z-axis direction relative to the first mounting plate 1; horizontal movement is movement in the X-axis direction relative to the first mounting plate 1; since the second mounting plate 2 is perpendicular to the first mounting plate 1, horizontal movement on the second mounting plate 2 is movement in the Y-axis direction relative to the first mounting plate 1. The specific shape of the loading slide 5 is as follows. Figure 1 As shown, the loading slide 5 is fixedly installed on the ground or other installation positions through the installation column below. The loading slide 5 is opposite to the assembly mechanism. The sealing ring is placed in the loading slide 5 and is sent into the assembly mechanism for assembly through the sealing ring bringing mechanism. The workpiece base 4 is arranged below the assembly mechanism. The top of the workpiece base 4 is provided with a placement hole for determining the position of the workpiece fixture 41. The workpiece fixture 41 can be placed on the top of the workpiece base 4 manually, or the workpiece base 4 can be transported together with the workpiece fixture 41 to the bottom of the assembly mechanism for assembly by means of instrument transmission. Preferably, the detection mechanism is an optical fiber sensor 3, and the optical fiber sensor 3 can be fixedly set at any position.

When the sealing ring downward transport cylinder 71 is started, the positioning carrier 72 will move downward, that is, move in the Z-axis direction relative to the first mounting plate 1, and the positioning carrier 72 will move to the upper side of the workpiece base 4 and face the workpiece fixture 41. When the switching cylinder 74 is started, the pre-installation rod 75 and the assembly rod 76 will move in the horizontal direction, that is, move in the X-axis direction relative to the first mounting plate 1. When the pre-installation rod 75 faces the positioning carrier 72 and reaches the pre-installation position, the assembly rod 76 will be on the outside of the positioning carrier 72; when the assembly rod 76 faces the positioning carrier 72 and reaches the installation position, the pre-installation rod 75 will be on the outside of the positioning carrier 72. When the sealing ring assembly cylinder 73 is started, the switching cylinder 74 will move downward together with the pre-installation rod 75 and the assembly rod 76, that is, move in the Z-axis direction relative to the first mounting plate 1. Finally, one of the pre-installation rod 75 and the assembly rod 76 enters the interior of the positioning carrier 72 and installs the sealing ring on the workpiece on the top of the workpiece fixture 41.

When the upper and lower bringing cylinders 82 are started, the hook body 83 will move upward and downward, that is, move in the Z-axis direction relative to the first mounting plate 1.

[0037] like Figure 4 As shown, a through hole is opened on the top of the positioning carrier 72, and the through hole and the workpiece fixture 41 are at the same center position; in this embodiment, the specific structure of the positioning carrier 72 is as follows Figure 4 As shown, the inner diameter of the through hole at the top is slightly larger than the diameter of the pre-installation rod 75 and the assembly rod 76.

[0038] like Figure 1 , Figure 6 As shown, the top of the workpiece fixture 41 is integrally formed with an anti-flip column 411 for preventing the sealing ring from flipping during the installation process. In this embodiment, when the pre-installation rod 75 is pre-installed, due to the shape of the pre-installation rod 75, when the pre-installation rod 75 passes through the positioning carrier 72 and enters the workpiece inner tube and pushes half of the sealing ring into the workpiece inner tube, the sealing ring may flip. The anti-flip column 411 can prevent the sealing ring from flipping and prevent the sealing ring from being installed incorrectly.

Therefore, the holes at the center position of the pre-installation rod 75 and the assembly rod 76 need to match the size and shape of the anti-flip column 411.

[0042] In the second step, the seal ring downward transport cylinder 71 is activated, the positioning carrier 72 moves downward, and finally falls on the workpiece on the top of the workpiece fixture 41. At this time, the upper and lower bringing cylinders 82 and the horizontal bringing cylinder 81 are activated to retract the hook body 83 to avoid it;

[0043] In the third step, the sealing ring assembly cylinder 73 is started, and the switching cylinder 74 moves downward together with the pre-installation rod 75 and the assembly rod 76. At this time, the pre-installation rod 75 first pre-installs the sealing ring on the inner cylinder of the workpiece, and the pre-installation rod 75 passes through the positioning carrier 72 and enters the inner cylinder of the workpiece, and presses half of the sealing ring into the groove for installing the sealing ring in the inner cylinder of the workpiece;

[0044] Step 4: The sealing ring assembly cylinder 73 is started to lift the pre-assembly rod 75 and the assembly rod 76 upwards, and the switching cylinder 74 is started to make the assembly rod 76 face the positioning carrier 72. The sealing ring assembly cylinder 73 is started to move the assembly rod 76 downwards, and the assembly rod 76 passes through the positioning carrier 72 and enters the workpiece inner cylinder, and presses the sealing ring as a whole into the groove for installing the sealing ring in the workpiece inner cylinder;

[0045] In the fifth step, the sealing ring assembly cylinder 73 is started to lift the pre-installation rod 75 and the assembly rod 76 upwards, and the optical fiber sensor 3 is started to detect whether the sealing ring is installed in place or whether it is installed.
