[0032] Referring to Figures 1-4 , according to an embodiment of a sealing ring assembling machine of the present utility model, it includes a processing table 11, and a clamping assembly 101 is arranged on the processing table 11. The clamping assembly 101 is used to sleeved a sealing ring upwardly outside a workpiece.

[0033] The clamping assembly 101 includes a loading table 21 arranged on the processing table 11. A loading platform 22 is fixedly arranged on the upper side surface of the loading table 21. A sleeve 23 is fixedly arranged on the upper side surface of the loading platform 22. A first cylinder 24 is also fixedly arranged on the loading platform 22. The end of a first piston rod extending out of the first cylinder 24 is equipped with a first push plate 25. The first push plate 25 is sleeved outside the sleeve 23 and can move up and down. It further includes a feeding mechanism 102 for sleeving the sealing ring outside the sleeve 23.

[0034] After there is a sealing ring outside the sleeve 23, a worker inserts the workpiece into the sleeve 23 and abuts against the upper side surface of the sleeve 23. Then, by controlling the first cylinder 24, the first push plate 25 moves upward. At this time, the sealing ring sleeved outside the sleeve 23 will be pushed upward by the first push plate 25 until it is sleeved on the workpiece.

[0035] In this embodiment, the feeding mechanism 102 includes a feeding tray 31 and a transfer table 32. The transfer table 32 is fixed on the loading table 21. A transfer groove 33 is arranged inside the upper side surface of the transfer table 32 ( Figure 2 and a sealing ring is also arranged in the transfer groove 33). The discharge port in the feeding tray 31 communicates with the transfer groove 33. In order to make the transmission of the sealing ring more stable and reliable and avoid the phenomenon of the sealing rings stacking, a transfer plate 37 is further arranged on the processing table 11. The transfer plate 37 is placed between the feeding tray 31 and the transfer table 32. Transfer grooves 38 arranged on the upper and lower side surfaces of the transfer plate 37 communicate with the transfer groove 33 and the discharge port. The groove depth of the transfer groove 38 is not greater than the thickness of two sealing rings in a stacked state, and a cover plate 39 is arranged on the transfer groove 38.

[0036] It further includes an outer support member for locking the sealing ring located in the transfer groove 33. The outer support member is fixed on the transfer plate 34. A second cylinder 35 is further provided on the transfer plate 34. The end of the second piston rod extending out of the second cylinder 35 is equipped with a second push plate 36, and the second push plate 36 is sleeved outside the outer support member.

[0037] It further includes a drive system for controlling the left - right and up - down movement of the transfer plate 34.

[0038] The outer support member includes a cylindrical portion 91 and a conical portion 92 integrally formed at the lower end of the cylindrical portion 91. A crack that penetrates left - right and front - back is provided in the cylindrical portion 91 and the conical portion 92. The second push plate 36 is sleeved outside the cylindrical portion 91.

[0039] A receiving groove for receiving the conical portion 92 and the cylindrical portion 91 is provided in the transfer groove 33, and a cross - shaped plate 93 is provided in the receiving groove. The position of the cross - shaped plate 93 is adapted to that of the crack.

[0040] Feeding process:

[0041] The sealing ring located in the feeding tray 31 will be pushed. After passing through the transfer groove 38 and placed in the transfer groove 33, the drive system controls the transfer plate 34 to move downward. At this time, the conical portion 92 and the cylindrical portion 91 are inserted into the cross - shaped plate 93, and the sealing ring located in the transfer groove 33 is sleeved outside the cylindrical portion 91.

[0042] After that, the transfer plate 34 moves upward. After the transfer plate 34 moves to the uppermost side, it moves to the right until the transfer plate 34 is above the sleeve 23. Then the transfer plate 34 moves downward and the conical portion 92 is inserted into the sleeve 23. Then the second cylinder 35 controls the second push plate 36 to move downward, and the sealing ring sleeved outside the cylindrical portion 91 is sleeved outside the sleeve 23. At this time, the feeding work of the sealing ring is completed. And after that, the operator can insert the workpiece into the sleeve 23 after the transfer plate 34 and the second push plate 36 reset upward, and push the sealing ring sleeved outside the sleeve 23 to the outside of the workpiece by making the first push plate 25 move upward. At this time, one - time feeding and installation work of the sealing ring is completed.

[0043] In the above process, in order to ensure that after the conical portion 92 is inserted into the sleeve 23, the sealing ring sleeved outside the cylindrical portion 91 can be smoothly pushed to the outside of the sleeve 23 instead of being embedded in the gap between the sleeve 23 and the conical portion 92, a chamfer is provided between the inner curved surface and the upper side surface of the sleeve 23, and the conical portion 92 can be attached to the chamfer.

[0044] In an embodiment of the drive system, the drive system includes a fixed plate 41 fixed to the processing table 11 through a bracket. An installation plate 42 is slidably connected left and right on the fixed plate 41, and a transfer plate 34 is slidably connected up and down to the installation plate 42.

[0045] A third cylinder 43 is arranged horizontally on the fixed plate 41 and is used to control the left and right movement of the installation plate 42. And a fourth cylinder 44 is arranged vertically on the installation plate 42 and is used to control the up and down movement of the transfer plate 34. That is, the staff can control the left and right positions of the installation plate 42 and the transfer plate 34 through the third cylinder 43, and control the up and down position of the second cylinder 35 through the fourth cylinder 44.

[0046] In addition, in order to avoid rigid collision between the first cylinder 24 when moving downward and the wall surface of the sleeve 23 or the transfer groove 33, two buffers 40 are further arranged on the processing table 11. The two buffers 40 are respectively located at the rear sides of the sleeve 23 and the transfer groove 33, and the buffer 40 can abut against the transfer plate 34.

[0047] It should be additionally noted that the described seal ring assembling machine is applicable to clamping seal rings made of elastic materials such as rubber.

[0048] The above are only specific embodiments of the present invention, but the technical features of the present invention are not limited thereto. Any changes or modifications made by those skilled in the art within the scope of the present invention are covered by the patent scope of the present invention.
