[0002] Sealing rings are elastic ring-shaped components used in many products requiring sealing. Currently, due to the wide variety of sizes and types of sealing rings, most sealing ring assembly on the market is done manually. This involves fitting the sealing ring onto a fixture with an enlarged diameter, manually peeling the sealing ring off the fixture, and then assembling it onto the product. Existing sealing ring assembly methods rely on manual visual alignment, resulting in poor assembly accuracy, increasing the defect rate of assembled products, and are also labor-intensive and inefficient.

[0044] The present invention will be further described in detail below with reference to the accompanying drawings.
[0045] like Figure 1 As shown, a sealing ring assembly machine includes a main body 10 and an assembly mechanism 1 disposed on the main body 10. The main body 10 is equipped with control devices such as a display screen and buttons.
[0046] like Figure 2 , 3 As shown in Figure 4, the specific structure of the assembly mechanism 1 includes a fixed cylinder 13, the rear end of which is fixedly connected to the main body 10. A spindle 11 is provided at the center of the fixed cylinder 13, and the spindle 11 is slidably connected to the fixed cylinder 13, and the spindle 11 can slide along the axial direction of the fixed cylinder 13. A swing block 12 is rotatably connected to the fixed cylinder 13. There are four swing blocks 12, which are evenly distributed around the front end of the fixed cylinder 13.
[0047] like Figure 5As shown, the mandrel 11 includes a first shaft 111, which is slidably disposed within the mandrel 11. A second shaft 112 is disposed at the front end of the first shaft 111 and is used to push the swing block 12. A top block 113 is disposed on the outer periphery of the second shaft 112, and there are four top blocks 113, which are respectively located in the gaps between adjacent swing blocks 12. Through the gaps, the top blocks 113 can move from the rear end of the retaining ring 122 to the front end of the retaining ring 122, thereby pushing out the sealing ring on the retaining ring 122.
[0048] like Figure 6 As shown, the swing block 12 includes a cone 121, which is oscillatingly disposed at the front end of the fixed cylinder 13. A retaining ring 122 is formed at the front end of the cone 121 for holding a sealing ring. The outer periphery of the retaining ring 122 has a groove for positioning the sealing ring.
[0049] A spring 15 is provided between the spindle 11 and the fixed cylinder 13. When the spindle 11 moves backward, it needs to overcome the elastic force of the spring 15.
[0050] A cylinder 14 is provided at the rear end of the fixed cylinder 13. The output end of the cylinder 14 can push the mandrel 11 forward, thereby moving the mandrel 11 forward.
[0051] like Figure 7 As shown, the fixed cylinder 13 includes a cylinder body 131, the rear end of which is fixedly connected to the main body 10. An inner groove 132 is formed within the cylinder body 131, and a first shaft 111 is slidably disposed within the inner groove 132. A guide groove 133 is provided in the inner groove 132, and a guide block 115 is provided on the first shaft 111, slidably disposed within the guide groove 133. The cooperation of the guide block 115 and the guide groove 133 allows the spindle 11 to move only along the axis of the fixed cylinder 13, without circumferential rotation. This ensures that the top block 113 is always positioned within the gap between adjacent swing blocks 12.
[0052] A hinge block 125 is provided at the rear end of the cone 121, and a hinge groove 134 is provided at the front end of the cylinder 131. The hinge block 125 and the hinge groove 134 are rotatably connected. A torsion spring is provided between the hinge block 125 and the hinge groove 134. The torsion spring can cause the front end of the swing block 12 to swing inward, thereby pressing the swing block 12 onto the spindle 11.
[0053] The front end of the second shaft 112 has a slot 114. The workpiece is inserted into the slot 114, thus positioning the workpiece. The workpiece has a sealing groove for installing a sealing ring, and the sealing groove is flush with the front end of the slot 114. After the sealing ring is detached from the mandrel 11, it can be directly embedded into the sealing groove on the workpiece.
[0054] The inner side of the swing block 12 is provided with a conical groove 123 and a cylindrical groove 124 that are connected to each other, and the cylindrical groove 124 is located at the front end of the conical groove 123.
[0055] When the second shaft 112 engages with the conical groove 123, the spindle 11 moves, driving the swing block 12 to swing. When the second shaft 112 engages with the cylindrical groove 124, the spindle 11 moves, but the swing block 12 does not swing.
[0056] Specific usage instructions:
[0057] a. In the initial state, the mandrel 11 is located at the rear end.
[0058] b. The torsion spring causes the front end of the swing block 12 to swing inward, and the distance between adjacent retaining rings 122 is short, so that the sealing ring can be fitted onto the retaining ring 122.
[0059] c. Place the sealing ring onto the retaining ring 122.
[0060] d. The cylinder 14 drives the spindle 11 to move forward. The second shaft 112 slides with the tapered groove 123. The spindle 11 pushes the swing block 12 open, and the front end of the swing block 12 swings outward. The distance between the adjacent retaining rings 122 increases, which opens the sealing rings fitted on the retaining rings 122.
[0061] e. The cylinder 14 drives the spindle 11 to continue moving forward. The second shaft 112 slides with the cylinder groove 124. At this time, the sealing ring is fully opened. The top block 113 is located in the gap between the adjacent swing blocks 12. The front end of the top block 113 pushes the opened sealing ring on the retaining ring 122 forward until the sealing ring is separated from the retaining ring 122 and the sealing ring moves to the second shaft 112.
[0062] f. Cylinder 14 retracts, and the extension rod of cylinder 14 disengages from the drive spindle 11.
[0063] g. Insert the workpiece into the slot 114 and push the mandrel 11 backward. The retaining ring 122 can push the sealing ring on the second shaft 112 onto the workpiece, thereby completing the assembly of the sealing ring.
[0064] Based on the above-described preferred embodiments of this utility model, and through the foregoing description, those skilled in the art can make various changes and modifications without departing from the technical concept of this utility model. The technical scope of this utility model is not limited to the contents of the specification, but must be determined according to the scope of the claims.
