[0028] To make the above-mentioned objects, features, and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a full understanding of this utility model. However, this utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this utility model. Therefore, this utility model is not limited to the specific embodiments disclosed below.

[0029] See Figure 1 and Figure 2 The diagram shows a schematic of the structure of a tooling for sealing the end of a composite jacket of a surge arrester in one embodiment of the present invention. It includes a base plate 100, a first end support component 200, a second end support component 300, and a top plate 400. The first end support component 200 and the second end support component 300 are disposed between the base plate 100 and the top plate 400.

[0030] like Figure 1As shown, the first end support assembly 200 includes a first lower locking block 210 disposed on the base plate 100, a first end groove 211 formed in the first lower locking block 210, two first connecting rods 220 respectively disposed on both sides of the first end groove 211, a first top block 230 connected to the first connecting rods 220, and a first top rod 240 threadedly connected to the first top block 230.

[0031] like Figure 2 As shown, the second end support assembly 300 includes two fixing blocks 310 respectively disposed on the base plate, two second connecting rods 320 respectively disposed on the fixing blocks 310, a second lower locking block 330 connected to the second connecting rods 320, a second end groove 331 opened in the second lower locking block 330, two third connecting rods 340 respectively disposed on both sides of the second end groove 331, a second top block 350 connected to the third connecting rods 340, and a second top rod 360 threadedly connected to the second top block 350.

[0032] See also Figure 1 and Figure 2 The top plate 400 is provided with a first upper locking block 410, the first upper locking block 410 has a third end groove 411, the first upper locking block 410 is detachably connected to the first lower locking block 210, and the third end groove 411 and the first end groove 211 are connected to form a first receiving cavity for accommodating the end 12 of the surge arrester composite jacket.

[0033] This fixture can be applied to single-end or double-end packaging. Before end sealing casting, the first end support assembly 200 and the second end support assembly 300 are both mounted on the base plate 100. One end of the surge arrester 10 to be sealed is placed on the upper part of the first end groove 211 of the first lower locking block 210, and the other end of the surge arrester 10 is placed on the upper part of the second end groove 331 of the second lower locking block 330. The top plate 400 is placed on the first end support assembly 200 and the second end support assembly 300. The first upper locking block 410 and the first lower locking block 330 are connected. Block 210 is detachably connected, and the third lower locking block 110 is detachably connected to the second upper locking block 420. The first push rod 240 and the second push rod 360 are rotated and adjusted to press against the surge arrester 10 from both ends, preventing axial displacement of the surge arrester 10 during processing. The surge arrester 10 is fixed in place. The entire fixture is moved so that the side of the second end support assembly 300 away from the first end support assembly 200 extends into the casting machine (not shown in the figure). The end 12 of the surge arrester composite jacket that needs to be sealed is fed into the casting machine for sealing, completing the sealing of one end at the casting position 13. See also... Figures 3-5 It should be noted that the sealing pouring position 13 is the joint position between the end flange and the main body of the surge arrester, that is, the sealing is performed near the end 12 of the composite outer sleeve of the surge arrester.

[0034] When the surge arrester 10 only requires single-end encapsulation, move the tooling to remove the end 12 of the surge arrester composite jacket, rotate and adjust the first top rod 240 and the second top rod 360 away from the surge arrester 10, separate the first upper locking block 410 from the first lower locking block 210, separate the third lower locking block 110 from the second upper locking block 420, lift the top plate 400, and disassemble the surge arrester 10.

[0035] When the surge arrester 10 requires double-end sealing, after completing the sealing and casting of one end, move the fixture to remove the end 12 of the composite outer sleeve of the surge arrester. Rotate and adjust the first top rod 240 and the second top rod 360 so that their ends are away from the surge arrester 10. Disassemble the first upper locking block 410 from the first lower locking block 210, and the third lower locking block 110 from the second upper locking block 420. Lift the top plate 400. Lift the surge arrester 10 and turn it around. Place the other end of the surge arrester 10 that needs end sealing and casting on the upper part of the first end groove 211 of the first lower locking block 210, and place the other end of the surge arrester 10 on the upper part of the second end groove 331 of the second lower locking block 330. Re-fix the surge arrester 10. Move the fixture so that the side of the second end support assembly 300 away from the first end support assembly 200 extends into the casting machine. The surge arrester composite sleeve end 12 located above the second end groove 331 is fed into the casting machine for casting to complete the sealing casting of the other end. The tooling is moved to remove the surge arrester composite sleeve end 12. The first top rod 240 and the second top rod 360 are rotated and adjusted away from the surge arrester 10. The first upper locking block 410 and the first lower locking block 210 are separated, and the third lower locking block 110 and the second upper locking block 420 are separated. The top plate 400 is lifted and the surge arrester 10 is disassembled.

[0036] Preferably, in one embodiment, a top plate is provided at the end of the first top rod 240 and the second top rod 360 respectively. By rotating the first top rod 240 or the second top rod 360, the top plate can move closer to or further away from the end of the surge arrester 10.

[0037] See also Figure 2 and Figure 5In one embodiment, through holes are respectively provided on both sides of the second end groove 331 on the second lower locking block 330. The second connecting rod 320 slidably passes through the through holes, and the locking bolt 321 is screwed into the second lower locking block 330 and abuts against the abutting surface 322 of the second connecting rod 320. Specifically, the abutting surface 322 is a plane provided on the upper part of the second connecting rod 320. In use, after loosening the locking bolt 321, the position of the second lower locking block 330 can be adjusted according to the length of the surge arrester 10 to be processed. After adjusting to a suitable position, the locking bolt 321 is tightened to lock the relative position of the second connecting rod 32 and the second lower locking block 330. This setting makes the tooling applicable to a wider range.

[0038] In one embodiment, a third lower locking block 110 is provided on the base plate 100, and a second upper locking block 420 is provided on the top plate 400. The third lower locking block 110 and the second upper locking block 420 are connected to form a second receiving cavity for accommodating the surge arrester composite jacket. The second receiving cavity is located between two adjacent umbrella skirts 11. In this embodiment, the addition of the third lower locking block 110 and the second upper locking block 420 between the first end support assembly 200 and the second end support assembly 300 makes the fixation of the surge arrester 10 more stable and reliable.

[0039] In one embodiment, the first lower locking block 210 and the first upper locking block 410 are detachably connected to two first locking pins 510 via a first locking piece 500. Based on this embodiment, the third lower locking block 110 and the second upper locking block 420 are detachably connected to two second locking pins 610 via a second locking piece 600. When the surge arrester 10 needs to be removed, the two first locking pins 510 and the second locking pins 610 can be quickly disassembled, and then the top plate 400 can be lifted for easy disassembly.

[0040] See Figure 3 and Figure 4 In one embodiment, first lifting blocks 120 are respectively provided on both sides of the base plate 100.

[0041] In one embodiment, a plurality of first connecting holes 130 are provided on both sides of the base plate 100, and two first lifting blocks 120 connected to the first connecting holes 130 are provided on each side of the base plate 100.

[0042] See Figure 3 and Figure 5 In one embodiment, a second lifting block 430 is provided on each side of the top plate 400.

[0043] Furthermore, multiple second connection holes 440 are provided on both sides of the top plate 400, and two second lifting blocks 430 connected to the second connection holes 440 are provided on each side of the top plate 400.

[0044] In specific settings, the first lifting block 120 and the second lifting block 430 can be set as U-shaped blocks, and the lifting blocks on both sides can be set symmetrically to facilitate lifting and movement. During lifting, the force is more evenly distributed and the safety is improved.
