The push rod allows the staff to push the right movable plate and the left movable plate to slide more conveniently. The movable hole provides a smooth sliding channel for the push rod, ensuring the stability and accuracy of the push, reducing the labor intensity of the staff and improving the convenience of operation.

DETAILED DESCRIPTION

[0026] The preferred embodiments of the present invention are described in detail below in conjunction with the accompanying drawings.

[0027] like Figure 1-Figure 7 As shown, a GIS three-station skeleton oil seal assembly jig includes a left side plate 1, which is arranged on the left side of a right side plate 2, and a plurality of guide rods 23 are connected between the right side plate 2 and the left side plate 1 by bolts. A right movable plate 3 is movably arranged on the left side of the right side plate 2, and a left movable plate 4 is movably arranged on the right side of the left side plate 1. The left movable plate 4 and the right movable plate 3 are respectively slidably sleeved on the plurality of guide rods 23, and a contact spring 5 is arranged between the left movable plate 4 and the right movable plate 3. The contact spring 5 is composed of a pressure plate pin 501, a disc spring 502, a fixing plate 503, a connecting rod 504, and a first positioning pin 505. The left movable plate 4 and the right movable plate 3 are respectively slidably sleeved on the plurality of guide rods 23. A fixing hole 6 is respectively provided on one side of the right movable plate 3, and the left and right sides of the fixing plate 503 can be slidably inserted in the two fixing holes 6 respectively. A transmission device 7 is detachably arranged between the left side plate 1 and the right side plate 2. The transmission device 7 consists of a transmission mounting plate 701, a first threaded hole 702, a lead screw 703, and a connecting sleeve 704. The interior of the first threaded hole 702 is threadedly connected to the threaded end of the lead screw 703, and the connecting sleeve 704 is rotatably arranged at the front end of the lead screw 703. Positioning holes 8 are respectively provided on one side of the left movable plate 4 and the right movable plate 3, and second positioning pins 9 are slidably inserted in the interiors of the two positioning holes 8.

[0028] During use, the staff first slides the right movable plate 3 and the left movable plate 4 to the appropriate position, puts the contact spring 5 parts into them, connects the connecting rod 504 to the right movable plate 3 and the left movable plate 4 through the second positioning pin 9, then clamps the fixed plate 503 on the fixing holes 6 of the right movable plate 3 and the left movable plate 4, rotates the screw 703 to make the transmission device 7 push the pressure plate pin 501 to move, thereby compressing the disc spring 502, and when the disc spring 502 is compressed to the required position, inserts the first positioning pin 505, so that the pressure plate pin 501 is connected to the connecting rod 504, and the contact spring 5 is installed. Then the staff makes the transmission device 7 move in the opposite direction by unscrewing the screw 703, pulls out the second positioning pin 9, slides the right movable plate 3 and the left movable plate 4 to the left and right sides, takes out the installed marine circuit breaker straightening mechanism contact spring 5, and the installation is completed.

[0029] The left side plate 1, the right side plate 2, the right movable plate 3, the left movable plate 4 and the transmission device 7 facilitate workers to effectively fix the contact spring 5 and its components, and at the same time determine the length and position of the contact spring 5, thereby improving the installation efficiency of the contact spring 5.

[0030] like Figure 2-Figure 4 and Figure 6 As shown, a bent plate 10 is detachably provided on the front side of the transmission mounting plate 701 , a directional hole 11 is opened on the front side of the bent plate 10 , and a connecting sleeve 704 is movably provided in the directional hole 11 .

[0031] During use, the introduction of the bent plate 10 and the directional hole 11 provides a stable guiding path for the connecting sleeve 704. The directional hole 11 ensures that the connecting sleeve 704 moves accurately in a straight line direction under the push of the lead screw 703, avoiding deviation or shaking, making the transmission process smoother and reducing friction and wear caused by motion trajectory deviation.

[0032] like Figure 1-Figure 7 As shown, a thrust bearing 12 is provided between the lead screw 703 and the connecting sleeve 704, a receiving plate 13 is fixed to the inner sides of the left movable plate 4 and the right movable plate 3 respectively, a plurality of first threaded grooves 14 are provided on the front side of the transmission mounting plate 701, a plurality of second threaded holes 15 are provided on the front side of the bent plate 10, a plurality of second threaded holes 15 are respectively threadedly connected with first bolts 16, and the threaded ends of the plurality of first bolts 16 are respectively threadedly connected with the internal threads of the plurality of first threaded grooves 14.

[0033] In use, the thrust bearing 12 is used to reduce friction. Since the transmission mounting plate 701 is fixed, the screw 703 rotates through the thrust bearing 12 to push the connecting sleeve 704 to slide forward and backward, thereby improving the transmission efficiency. The receiving plate 13 is used to provide additional support for the connecting rod 504, thereby enhancing the stability of the connecting rod 504 during the compression process, reducing the loosening or damage of components that may be caused by vibration or impact, and improving the overall stability of the contact spring 5 during assembly. The first bolt 16 is used to facilitate the staff to disassemble or replace the bent plate 10, simplifying the maintenance process and improving the convenience of maintenance and adjustment.

[0034] like Figure 1-Figure 7 As shown, two second thread grooves 17 are respectively provided on the left and right sides of the transmission mounting plate 701, and two third threaded holes 18 are respectively provided on one side of the left plate 1 and the right plate 2, and second bolts 19 are respectively threadedly connected in the two third threaded holes 18, and the threaded ends of the two second bolts 19 are respectively threadedly connected to the internal threads of the two second thread grooves 17, and washers 20 are provided on the plurality of first bolts 16 and the plurality of second bolts 19, and push rods 21 are respectively fixed on the outer sides of the left plate 1 and the right plate 2, and movable holes 22 are respectively provided on one side of the right movable plate 3 and the left movable plate 4, and the two push rods 21 are respectively slidably inserted in the two movable holes 22.

[0035] In use, the transmission device 7 can be easily disassembled and replaced by the second bolt 19, while also ensuring the sealing and stability of the connection parts, simplifying the maintenance process, and improving work efficiency. The washer 20 is conducive to increasing the contact area between the first bolt 16, the second bolt 19 and the connecting piece, thereby dispersing the fastening force and preventing the first bolt 16 and the second bolt 19 from being crushed by the surface of the fastener. At the same time, the washer 20 can also play a certain anti-loosening role and enhance the stability of the connection. The push rod 21 allows the staff to more conveniently push the right movable plate 3 and the left movable plate 4 to slide. The movable hole 22 provides a smooth sliding channel for the push rod 21, ensuring the stability and accuracy of the push, reducing the labor intensity of the staff, and improving the convenience of operation.
