[0028] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative efforts belong to the scope of protection of the present invention.

[0029] Refer to Figures 1 - 7 , Figure 1 Stereogram of the special-shaped static seal ring assembling machine of the present invention; Figure 2 Exploded view of the special-shaped static seal ring assembling machine of the present invention; Figure 3 Top view of the special-shaped static seal ring assembling machine of the present invention; Figure 4 For the present invention Figure 3 Sectional view in the B-B direction in ; Figure 5 For the present invention Figure 4 Sectional view in the C-C direction in ; Figure 6 For the present invention Figure 5 Partial enlarged view of A in ; Figure 7 Effect diagram of installing copper row flange on the special-shaped static seal ring assembling machine of the present invention.

[0030] A special-shaped static seal ring assembling machine, comprising a bracket 390 and a table 360 connected to the bracket 390. An assembling body is fixed on the table 360. The assembling body includes an upper assembling body 341 and a lower assembling body 342 which are connected up and down. A receiving hole is formed in the middle of the upper assembling body 341. A regular-shaped block 310 is arranged in the receiving hole. A seal ring assembling hole 410a is formed between the inner wall of the receiving hole and the outer wall of the regular-shaped block 310. A seal ring assembling block 330 is inserted into the seal ring assembling hole 410a. An assembling ejector rod 350 sequentially penetrates through the lower assembling body 342 and the table 360 at the lower end of the seal ring assembling block 330. A first power cylinder 380 is arranged on the bracket 390. The power push rod end of the first power cylinder 380 is connected to an assembling top plate 370. The assembling top plate 370 can jack up the assembling ejector rod 350 and push the seal ring assembling block 330 to move up and down.

[0031] The first power cylinder 380 can be a hydraulic cylinder or a pneumatic cylinder, preferably a pneumatic cylinder. The first power cylinder 380 can push the assembling ejector rod 350 to move up and down, so that the assembling ejector rod 350 pushes the seal ring assembling block 330 to move up and down, realizing the extrusion assembly of the special-shaped static seal ring.

[0032] The shape and size of the regular-shaped block 310 match those of the special-shaped static seal ring, and a jack for inserting a copper bar is arranged inside it. Correspondingly, the assembling body and the seal ring assembling block 330 are also provided with jacks for inserting copper bars.

[0033] A plurality of centering and guiding blocks 320 facing the regular-shaped block 310 are arranged on the upper assembling body 341. The centering and guiding blocks 320 are arranged along the inner wall edge of the receiving hole in the upper assembling body 341. One side of the centering and guiding blocks 320 is clamped on the upper assembling body 341, and the other side extends into the seal ring assembling hole 410a.

[0034] When assembling the special-shaped static seal ring 410, the staff places the special-shaped static seal ring 410 in the seal ring assembling hole 410a for limit correction. Because the special-shaped static seal ring 410 is soft in texture and easy to deform, it is easy to deform and tilt during assembly. At this time, a plurality of centering and guiding blocks 320 facing the regular-shaped block 310 are arranged on the upper assembling body 341 to extrude the circumference of the special-shaped static seal ring 410, which can ensure that the special-shaped static seal ring 410 will not tilt or shift.

[0035] The usage method of the special-shaped static seal ring 410 assembly machine of the present invention is as follows: The staff places the special-shaped static seal ring 410 into the seal ring assembly hole 410a and straightens it by the extrusion of the straightening guide block 320; then, a copper row flange 400 is placed on the upper assembly body 341, and the position of the copper row flange 400 corresponds to that of the special-shaped static seal ring 410; the first power cylinder 380 moves, drives the assembly top plate 370, and pushes the assembly ejector rod 350 to move upward. There is a gap between the assembly ejector rod 350 and the assembly top plate 370, which is a floating connection, thereby reducing the machining accuracy requirements for the hole at the assembly ejector rod 350 and reducing the processing cost. Through the seal ring assembly block 330, the special-shaped static seal ring 410 is extruded and assembled into the sealing groove of the flange 400.

[0036] Further, as Figure 5 shown, an annular groove is provided at the lower part of the assembly ejector rod 350, a snap spring 350a is clamped in the groove, and a second spring 350b abuts between the lower surface of the table 360 and the snap spring 350a. When the assembly ejector rod 350 is pushed upward, the second spring 350b is in a compressed state, so as to drive the assembly ejector rod 350 to fall back to its original position by pushing the snap spring 350a. Through the cooperation of the detachable snap spring 350a and the annular groove, while playing a limiting role for the second spring 350b, it replaces the fixed limiting block structure and is convenient for installation. As Figure 4 shown, a stepped limiting groove is provided at the mating part of the upper part of the assembly ejector rod 350 and the lower assembly body 342 to limit the falling position of the assembly ejector rod 350.

[0037] Further, the seal ring assembly block 330 includes an assembly push plate 331 and an assembly push block 332 connected to the assembly push plate 331 and having a shape and size matching the seal ring assembly hole 410a.

[0038] During assembly, the assembly push plate 331 can move under the thrust of the assembly ejector rod 350, and the assembly push block 332 can be inserted into the seal ring assembly hole 410a to extrude and assemble the special-shaped static seal ring 410.

[0039] Further, an avoidance groove 332a allowing the straightening guide block 320 to pass through is provided on the side wall of the assembly push block 332. By providing the avoidance groove 332a, the assembly push block 332 can move up and down through the straightening guide block 320.

[0040] Further, a seal ring detection sensor 500 is also provided on the special-shaped static seal ring assembly machine to detect whether the special-shaped static seal ring 410 is installed in the sealing groove of the copper row flange 400.

[0041] Refer to Figures 8 - 11 , Figure 8Stereogram of the automatic oiling device for oiling the special-shaped static seal ring assembling machine of the present invention; Figure 9 Partial enlarged view of A in the present invention 8; Figure 10 Cross-sectional view of the automatic oiling device for oiling the special-shaped static seal ring assembling machine of the present invention; Figure 11 Partial enlarged view of B in the present invention 10.

[0042] The special-shaped static seal ring assembling machine further includes an automatic oiling device for oiling, including an oiling reserve barrel 650 and an automatic oiling device, and the oiling reserve barrel 650 and the automatic oiling device are connected through an oil pipeline 660.

[0043] The copper row connector mainly includes a flange and a copper row inserted on the flange. The flange is provided with copper row insertion holes corresponding to the position and quantity of the copper rows. When assembling the copper row connector, if the copper row insertion holes are dry and rough, it is not easy to insert the copper row. Generally, lubricating oil needs to be applied at the position of the copper row insertion holes to facilitate insertion.

[0044] Through researching and developing an automatic oiling device for oiling the special-shaped static seal ring assembling machine, the present invention automatically applies lubricating oil to the copper row insertion holes through the equipment of the present invention, which is automatic and efficient.

[0045] The automatic oiling device includes an oiler 610, an oil supply port 630 connected to the oiler 610 through an oil path, and an oiling head 640 communicated with the oil supply port 630 through an oil path.

[0046] The oiler 610 is connected to the oiling reserve barrel 650 through an oil pipeline 660, and an oil path on-off supply solenoid valve 620 is connected to the oil pipeline 660. By connecting the oil path on-off supply solenoid valve 620 to the oil pipeline 660, the transmission of oiling in the oil path can be automatically controlled.

[0047] A separation tooling is provided at the lower part of the oiler 610. The separation tooling includes an upper pressure plate 670 connected to the lower part of the oiler 610, a spring 650 connected to the upper pressure plate 670, and a lower pressure plate 680 connected to the lower end of the spring 650; a through hole for the oiling head 640 to pass through is opened on the lower pressure plate 680.

[0048] By setting the separation tooling, when the automatic oiling device for oiling the special-shaped static seal ring assembling machine works, the automatic oiling device descends, the spring 650 is compressed, and the oiling head 640 passes through the through hole of the lower pressure plate 680 to oil the copper row insertion holes. When the separation tooling separates at the end of oiling, due to the action of the spring 650, it can be ensured that the copper row connector is not connected with the present invention, and the normal automatic operation of the equipment is guaranteed.

[0049] The oiling head 640 is wrapped with a sponge 660, and the oiling head 640 oils the copper row insertion holes by wetting the sponge 660, making the oiling more uniform.

[0050] The upper end of the automatic oiling device is connected to a second power cylinder, which can be a hydraulic cylinder or a pneumatic cylinder, preferably a pneumatic cylinder. Since the automatic oiling device is suspended, during oiling, the power cylinder is required to lift and lower the automatic oiling device to align with the copper busbar jack position for oiling.

[0051] The automatic oiling device for oiling of the special-shaped static seal ring assembling machine of the present invention: During the oiling operation, the second power cylinder controls the automatic oiling device to descend, the spring 650 is compressed, the oiling head 640 passes through the lower pressing plate 680 and presses into the oiling position of the copper busbar jack, and the oil path on-off supply solenoid valve 620 supplies oil. The oiling is distributed to each oiling head 640 through the oiler 610 to oil the copper busbar jack, ensuring uniform supply of the oiling amount; when separating after oiling, the spring 650 rebounds, which can ensure that the copper busbar connector is not connected to the present invention, and the equipment operates automatically and normally.

[0052] A special-shaped static seal ring assembling machine provided by an embodiment of the present invention has the following beneficial effects: By developing a special-shaped static seal ring assembling machine, the automatic assembly of special-shaped static seal rings can be carried out, which is automatic, efficient, time-saving and labor-saving, and greatly improves the installation efficiency of special-shaped static seal rings; by developing an automatic oiling device for oiling the special-shaped static seal ring assembling machine, manual oiling is replaced, the labor force is liberated, the oiling efficiency is improved, and it is simple and efficient; a separation tooling is arranged on the automatic oiling device. When the equipment separates after oiling, through the rebound of the spring, it can ensure that the copper busbar connector is not connected to the present invention, and the equipment operates automatically and normally.
