[0030] A detection mechanism 3, the side wall of the connecting plate 22 is fixedly connected with an L-shaped mounting plate 31, the detection mechanism 3 is fixedly installed on the top of the L-shaped mounting plate 31, and the detection mechanism 3 is used to detect whether the sealing ring is installed in place;
[0031] In this embodiment, both the oil outlet mechanism and the jaw mechanism need to be installed at fixed positions during operation. The second mounting plate 11 and the first mounting plate 21 can be installed on the wall, or on the side walls of a gantry, a frame, and other machinery, as long as the positional relationship between the oil outlet mechanism and the jaw mechanism is as Figure 1 , Figure 2 shown. The second mounting plate 11 and the first mounting plate 21 are common components for fixing in the prior art. Both the oil liquid extrusion cylinder 14 and the oil outlet cylinder 12 are fixed on the second mounting plate 11. When the oil outlet cylinder 12 is started, the oil liquid in the oil liquid extrusion cylinder 14 will be extruded.
[0032] The jaw opening and closing cylinder 24, the sealing ring assembling jaw 25, and the connecting plate 22 are jointly installed at the output end of the jaw lifting cylinder 23, and the connecting plate 22 is a commonly used component in the prior art for connecting the output end of the cylinder and other components. The specific structure of the sealing ring assembling jaw 25 is as Figure 1As shown, after the seal ring assembly jaw 25 closes, it will form a circular area with a diameter slightly larger than the outer diameter of the oil extrusion cylinder 14. When it closes, it can just surround the oil extrusion cylinder 14. When the jaw lifting cylinder 23 is activated, the jaw opening / closing cylinder 24 and the seal ring assembly jaw 25 will move in the vertical direction.
[0033] In this embodiment, the detection mechanism 3 is an optical fiber sensor. It is installed at the top of the L-shaped mounting plate 31 on the side wall of the connecting plate 22. The detection end of the optical fiber sensor faces the groove on the workpiece 4 for installing the seal ring. Whether the seal ring is installed in place is detected by the optical fiber sensor. At the same time, the detection mechanism 3 can also be installed at other positions where the seal ring on the workpiece 4 can be detected.
[0034] As Figure 2 、 Figure 4 、 Figure 5 shown, the oil extrusion cylinder 14 includes an oil outlet ejecting piston rod 15, a hollow oil injection channel 16 and a workpiece jig 17; a connecting groove 131 is opened at the top of the connecting seat 13. One end of the oil outlet ejecting piston rod 15 is inserted into the connecting groove 131, and the other end of the oil outlet ejecting piston rod 15 is slidably connected inside the hollow oil injection channel 16 and forms a piston fit with the hollow oil injection channel 16. A workpiece jig 17 is inserted at the upper opening of the hollow oil injection channel 16, and a workpiece 4 is arranged at the top of the workpiece jig 17; in this embodiment, the specific shapes of the oil outlet ejecting piston rod 15 and the hollow oil injection channel 16 are as Figure 5 shown. The hollow oil injection channel 16 is a hollow structure, and a cavity for injecting oil is opened inside the hollow oil injection channel 16. The oil outlet ejecting piston rod 15 can eject the oil inside the hollow oil injection channel 16 from its upper opening. The specific shape of the connecting seat 13 is as Figure 4 shown. The connecting groove 131 is T-shaped, and two annular flanges are formed at one end of the oil outlet ejecting piston rod 15 connected to the connecting groove 131. The oil outlet ejecting piston rod 15 is inserted into the connecting groove 131 through the two annular flanges.
[0035] As Figure 5 、 Figure 6 、 Figure 7 shown, a connecting portion 171 is integrally formed at the bottom of the workpiece jig 17. The workpiece jig 17 is inserted into the upper opening of the hollow oil injection channel 16 through the connecting portion 171. An oil inlet channel 172 is opened inward at the bottom of the connecting portion 171, and an oil outlet hole 173 is opened on the outer side wall of the workpiece jig 17. The oil outlet hole 173 is communicated with the oil inlet channel 172; in this embodiment, the connection relationship between the connecting portion 171 and the hollow oil injection channel 16 is as Figure 6As shown, the oil in the hollow oil injection channel 16 can enter the interior of the workpiece fixture 17 through the oil inlet channel 172 at the bottom of the connecting part 171. When the oil outlet cylinder 12 is activated, the oil outlet ejecting piston rod 15 will enter the interior of the hollow oil injection channel 16 and push the oil towards the workpiece fixture 17. The oil enters the interior of the workpiece fixture 17 through the oil inlet channel 172 and flows out to the outer side wall of the workpiece fixture 17 through the oil outlet hole 173.
[0036] As Figure 3 , Figure 5 shown, a positive pressure oil injection hole 161 is provided at the bottom of the side wall of the hollow oil injection channel 16. The hollow oil injection channel 16 is connected to an external oil supply system through the positive pressure oil injection hole 161; in this embodiment, the position of the positive pressure oil injection hole 161 is as Figure 3 , Figure 5 shown. The oil in the hollow oil injection channel 16 is provided by an external oil supply system. The external oil supply system can accurately control the oil output. Each time the hollow oil injection channel 16 is filled with oil, only the oil required for a single sealing ring is provided. The advantage of this is that it can save oil, keep the construction work station clean, and ensure the same uniformity of oil for each sealing ring.
[0037] As Figure 7 shown, a workpiece groove 174 that can match a variety of workpieces 4 is provided at the top of the workpiece fixture 17; in this application, various models of workpieces 4 can use this device for oiling and installing sealing rings. Their common point is that the sealing rings are all installed in the sealing ring installation grooves on the outer side wall of the workpiece 4, and the diameter of the sealing ring installation groove is smaller than the diameter of the workpiece fixture 17. The workpiece 4 is not the invention point to be protected by this device, so it will not be elaborated in detail Figure 1 , Figure 2 All clearly show the installation position of the sealing ring.
[0038] The implementation principle of this embodiment of the utility model is as follows:
[0039] First, the sealing ring is expanded by a manipulator and sleeved on the outer side wall of the workpiece fixture 17. The jaw lifting cylinder 23 and the jaw opening and closing cylinder 24 are activated to open the sealing ring assembly jaw 25 and move it to the upper side of the sealing ring. The jaw opening and closing cylinder 24 is closed, and the jaw lifting cylinder 23 descends to push the sealing ring downward until the sealing ring is located below the oil outlet hole 173. Then, the workpiece 4 with the sealing ring to be installed is placed in the workpiece groove at the top of the workpiece fixture 17.
[0040] Second, the jaw lifting cylinder 23 and the jaw opening and closing cylinder 24 are activated to open the sealing ring assembly jaw 25 and move the sealing ring assembly jaw 25 to the lower side of the sealing ring, and then the sealing ring assembly jaw 25 is closed.
[0041] Next, the oil outlet cylinder 12 descends, causing the oil outlet ejector piston rod 15 to descend to the lower side of the positive pressure oil injection hole 161. Oil is injected through the positive pressure oil injection hole 161 by an external oil supply system. After that, the oil outlet cylinder 12 extends, and the oil outlet ejector piston rod 15 will enter the hollow oil injection channel 16 and push the oil to the workpiece fixture 17. The oil enters the interior of the workpiece fixture 17 from the oil inlet channel 172 and flows out to the outer side wall of the workpiece fixture 17 through the oil outlet hole 173.
[0042] Finally, the gripper lifting cylinder 23 ascends, causing the seal ring assembly gripper 25 to push the seal ring through the oil outlet hole 173 for oil coating. The gripper lifting cylinder 23 continues to ascend, causing the seal ring assembly gripper 25 to continue pushing the seal ring to the workpiece 4. The seal ring undergoes elastic deformation and returns to its original shape, and is sleeved in the corresponding seal ring installation groove on the workpiece 4.
[0043] Repeat the above steps to complete the oil coating and assembly of the seal ring on the outer side of the workpiece 4.
[0044] The above shows and describes the basic principles, main features, and advantages of the present invention.
