[0022] The present invention will be further described in detail below in conjunction with the drawings and specific embodiments.

[0023] The device for simultaneously assembling upper and lower sealing rings is installed on the workbench and the mounting frame above the workbench, and is used in cooperation with the vibrating disk mechanism for providing the sealing rings. As shown in Figures 1 to 4 , it includes an upper mechanism, a middle mechanism, and a lower mechanism.

[0024] The upper mechanism is used to provide and assemble the upper sealing ring 18, and includes a translation cylinder 6, a pressing cylinder 7, a first guide post 8, a first material channel 10, a first base 11, a first lifting cylinder 12, and an unloading mechanism; wherein, the unloading mechanism includes an unloading cylinder 13 and an unloading baffle 14.

[0025] Below the upper mechanism, there is a middle mechanism for placing the part body 9 and assembling it. The middle mechanism is detachably arranged on the workbench by bolts. The middle mechanism includes a part base 5, a support mechanism, and a second guide post 4; among them, the support mechanism includes a support rod 15 and a setscrew 16.

[0026] Below the middle mechanism, there is a lower mechanism for providing and assembling the lower sealing ring 17. The lower mechanism includes a second lifting cylinder 1, a second base 2, and a second material channel 3.

[0027] The controlled ends of the upper mechanism, the middle mechanism, and the lower mechanism are all connected to the PLC controller.

[0028] The upper mechanism includes a translation cylinder 6 horizontally arranged on the mounting frame. Below the translation cylinder 6, there is a vertically arranged pressing cylinder 7 connected. The telescopic end of the pressing cylinder 7 is connected to a vertically arranged first guide post 8. The first guide post 8 is cylindrical, used to carry the upper sealing ring 18 and move it with the upper sealing ring 18, and the bottom end of the first guide post 8 is chamfered.

[0029] The pressing cylinder 7 is also provided with a material discharging mechanism for pushing the upper sealing ring 18 to discharge materials for installation. The material discharging mechanism includes a material discharging cylinder 13 vertically arranged downward and connected to the outer wall of the pressing cylinder 7. The telescopic end of the material discharging cylinder 13 is connected to a material discharging baffle 14, and the controlled end of the material discharging cylinder 13 is connected to the PLC controller. The material discharging baffle 14 includes a connecting rod and a collar sleeved on the first guide post 8. The connecting rod connects the collar and the material discharging cylinder 13, and the opening of the collar is larger than the first guide post 8 and smaller than the outer diameter of the upper sealing ring 18.

[0030] Below the material discharging mechanism, there is a first lifting cylinder 12 vertically arranged upward. The telescopic rod of the first lifting cylinder 12 is connected to a horizontally arranged first base 11. The first base 11 is used to convey and temporarily store the upper sealing ring 18. The first base 11 is communicated with the vibrating disk mechanism through a first material channel 10. A round hole for preventing against the end of the first guide post 8 is arranged on the first base 11, and the diameter of the round hole is smaller than the outer diameter of the upper sealing ring 18. The controlled ends of the horizontal cylinder, the pressing cylinder 7, the material discharging mechanism, and the first lifting cylinder 12 are connected to the PLC controller.

[0031] The middle mechanism includes a part base 5 horizontally arranged on the workbench for placing parts. The lower end face of the part base 5 is provided with a support mechanism. A second guide post 4 vertically arranged and cylindrical, used to carry the lower sealing ring 17, is assembled on the support mechanism. The diameter of the second guide post 4 is slightly larger than the bottom of the part. A pair of axial grooves are opened in the middle of the side wall of the second guide post 4, and the bottom end of the second guide post 4 is chamfered.

[0032] The support mechanism includes a π-shaped mounting base connected to the part base 5. A support rod 15 with one end inserted into the groove is hinged on the mounting base. A vertical set screw 16 is provided on the outer side wall of the mounting base. The set screw 16 is used to limit the rear end of the support rod 15, so that the front end in contact with the second guide post 4 cannot fall, supporting the second guide post 4.

[0033] The lower mechanism includes a second base 2 arranged below the part base 5 and used to support the lower sealing ring 17. An opening for placing and abutting against the end of the second guide post 4 is provided on the second base 2, and the diameter of the opening is smaller than the outer diameter of the lower sealing ring 17. A vertically arranged second lifting cylinder 1 is connected below the second base 2. The second base 2 is communicated with the vibrating disk mechanism through a second material channel 3, and the controlled end of the second lifting cylinder 1 is connected to the PLC controller.

[0034] When the present invention is actually used, the initial position of the translation cylinder 6 is such that the first guide post 8 is directly above the part body 9. As the translation cylinder 6 extends and moves to directly above the first base 11, the upper sealing ring 18 is sent to the first base 11 by the vibrating disk mechanism through the first material channel 10. The first base 11 is mounted on the first lifting cylinder 12, and the first lifting cylinder 12 jacks up, driving the first base 11 to move upward together until the upper sealing ring 18 is sleeved onto the position of the first guide post 8. The first guide post 8 is inserted into the round hole on the first base 11, and the upper sealing ring 18 will not fall into the recessed round hole. At this time, the upper sealing ring 18 is supported by the first base 11. As the first guide post 8 is inserted into the first base 11, the upper sealing ring 18 is sleeved onto the first guide post 8. At this time, the first lifting cylinder 12 moves down to return to its original position, and the translation cylinder 6 drives the upper part mechanism to return to the initial position, so that the first guide post 8 with the upper sealing ring 18 is directly above the part body 9.

[0035] The lower sealing ring 17 is sent to the second base 2 by the vibrating disk mechanism through the second material channel 3. The second base 2 is directly below the second guide post 4. The second lifting cylinder 1 jacks up, and the pressing cylinder 7 ejects downward.

[0036] The material-removing cylinder 13, the material-removing baffle 14 and the first guide post 8 are fixedly assembled on the pressing cylinder 7. The material-removing baffle 14 is assembled through the first guide post 8, and as the pressing cylinder 7 is pushed downward, the three move downward at the same time. After moving down to the position where the bottom of the first guide post 8 fits with the top of the part body 9, the pressing cylinder 7 stops moving, and the part body 9 is pressed against the part base 5. At this time, the material-removing cylinder 13 extends out, driving the material-removing baffle 14 to move downward. Since the through hole of the material-removing baffle 14 is slightly smaller than the outer diameter of the upper sealing ring 18, the upper sealing ring 18 on the first guide post 8 is moved downward together with the material-removing baffle 14. The material-removing baffle 14 drives the upper sealing ring 18 from the first guide post 8 through the middle tightly fitting position to the position where the upper end of the part body 9 needs to be assembled. The contact position between the bottom of the first guide post 8 and the top of the part body 9 is designed so that the bottom diameter of the first guide post 8 is slightly larger than the direct size of the top of the part body 9, ensuring that the upper sealing ring 18 will not be squeezed and worn at the fitting connection when it moves down from the first guide post 8 to the top of the part body 9. At this time, the upper sealing ring 18 is installed in place, and the material return cylinder 13 and the downward pressure cylinder 7 return to their positions and move up, completing a complete action.

[0037] At the same time as the above actions, the second base 2 is driven to move upward. As it moves upward, the second guide post 4 is inserted into the opening on the second base 2. The lower sealing ring 17 is supported by the second base 2 at this time. As the second base 2 is pushed up and inserted into the second guide post 4, the lower sealing ring 17 is put on the second guide post 4. The second lifting cylinder 1 continues to push up, and the lower sealing ring 17 continues to move upward under the force, and the second guide post 4 moves upward under the friction force of the lower sealing ring 17. As it moves upward, the front end of the support rod 15 in contact with the second guide post 4 is pushed open, and the second guide post 4 is separated from the support rod 15. The bottom cylinder of the part body 9 is now tightly fitted with the upper end of the second guide post 4, and the part body 9 is pressed by the upper part mechanism and cannot move. The lower sealing ring 17 is unhindered from the second guide post 4 through the position where the second guide post 4 is tightly connected to the bottom of the part body 9 to the position where the lower sealing ring 17 is required to be assembled on the bottom of the part body 9. After the lower sealing ring 17 passes through the second guide post 4, the second guide post 4 falls due to gravity. Since the support rod 15 is designed to have a long distance from the front end of the second guide column 4 to the fulcrum and a short part of the rear end supported by the top screw 16, the front end of the support rod 15 falls down, and the rear end returns to the position restricted by the top screw 16. During this process, the support rod 15 is inserted into the grooves on both sides of the second guide column 4, supporting the second guide column 4 so that it does not fall and continues to hang in the original position. At the same time, the second lifting cylinder 1 finishes the work with the second base 2 and returns to the original position below.

[0038] At this time, the lower sealing ring 17 and the upper sealing ring 18 of the part body 9 have been installed in place. The mechanism returns to its original position and circulates to prepare for the next assembly of the sealing ring.
