The stationary end clamping plate 3 and the moving end clamping plate 4 are respectively provided with clamping holes that match the two ends of the vacuum interrupter 6. The two positioning rods 101 of each hanger assembly 1 pass through the stationary end clamping plate 3 and the moving end clamping plate 4 and are connected to the stationary end clamping plate 3 and the moving end clamping plate 4 by fasteners. The rotating shafts 103 of the two hanger assemblies 1 are arranged in opposite directions, and the two bushings 201 of the boom assembly 2 are respectively sleeved on the two rotating shafts 103.

[0039] The method of using the aforementioned silver-plated flip-type fixture for vacuum interrupters includes the following steps:

[0040] The vacuum interrupter 6 is installed on the silver-plated flip-type fixture of the vacuum interrupter;

[0041] Lift vacuum interrupter 6 and first complete the electroplating of one end, either the moving end or the stationary end, on the line;

[0044] Example 1

[0045] This embodiment of a vacuum interrupter silver-plated flip-type fixture includes two hanger assemblies 1, a boom assembly 2, a stationary end clamping plate 3, and a moving end clamping plate 4.

[0046] The hanger assembly 1 includes a channel-shaped bent plate 102, with positioning rods 101 connected to a set of opposite sides of the channel-shaped bent plate 102. A rotating shaft 103 is connected to the center of the end face of the channel-shaped bent plate 102, and the rotating shaft 103 passes through the channel-shaped bent plate 102.

[0047] Specifically, the positioning rod 101 is a screw.

[0048] The grooved bending plate 102 has a flat plate, and L-shaped plates are connected to a pair of opposite sides of the flat plate. The two L-shaped plates are arranged back to back. One end of each L-shaped plate is connected to the flat plate, and the other end is connected to the positioning rod 101. A fixing plate 104 is connected between the two L-shaped plates, and the rotating shaft 103 passes through the end of the grooved bending plate 102 and is connected to the fixing plate 104.

[0049] Specifically, the rotating shaft 103 and the fixed plate 104 are welded together.

[0050] The grooved bending plate 102 has two positioning holes 105 on its flat plate, and the two positioning holes 105 are centrally distributed about the axis of rotation 103.

[0051] The boom assembly 2 includes a boom 203, which comprises two straight rods connected by a U-shaped member. The U-shaped member has a protruding hook for connecting a hook. Each straight rod of the boom 203 has a bushing 201 connected to its end. Specifically, the outer surfaces of the boom 203 and the bushing 201 are welded together.

[0052] Preferably, the boom assembly 2 further includes a reinforcing plate 202. The reinforcing plate 202 has through holes on its top and sides, with the two through holes being perpendicular to and interconnected. The straight rod of the boom 203 passes through the through hole at the top of the reinforcing plate 202 and is fixedly connected to it. The bushing 201 passes through the through hole at the bottom of the reinforcing plate 202 and is fixedly connected to it. The end of the straight rod of the boom 203 extending into the reinforcing plate 202 is connected to and fixedly connected to the outer wall of the bushing 201. Because the surface of the bushing 201 is curved, welding the boom 203 to the bushing 201 directly would not be secure. By using the reinforcing plate 202 to connect the boom 203 and the bushing 201, the structure of the boom assembly 2 becomes more stable.

[0053] Preferably, a reinforcing rod 204 is connected between the two straight rods of the boom 203 to prevent deformation of the two straight rods of the boom 203 when the boom assembly 2 is lifted. This meets the load-bearing requirements for lifting large arc-extinguishing chambers.

[0054] Both the stationary end clamping plate 3 and the moving end clamping plate 4 are provided with through holes, and the vacuum interrupter 6 is clamped between the stationary end clamping plate 3 and the moving end clamping plate 4.

[0055] Two opposing hanger assemblies 1 are provided on the stationary end plate 3 and the moving end plate 4. Four corresponding through holes are provided on each of the stationary end plate 3 and the moving end plate 4. Four positioning rods 101 pass through the stationary end plate 3 and the moving end plate 4 respectively, with both ends extending out of the stationary end plate 3 and the moving end plate 4. The rotating shafts 103 on the hanger assemblies 1 are arranged opposite each other and along the same axial direction.

[0056] The positioning rod 101 extends outward from the stationary end clamping plate 3 and is provided with a stationary end first fastener 301. A stationary end second fastener 303 is also provided on the positioning rod 101. The stationary end clamping plate 3 is positioned between the stationary end second fastener 303 and the stationary end first fastener 301, thereby securing the stationary end clamping plate 3. A stationary end insulating pad 302 is provided on the inner side of the stationary end clamping plate 3, positioned between the stationary end second fastener 303 and the stationary end clamping plate 3. Further, the positioning rod 101 is also provided with a stationary end reinforcing fastener 304, positioned at the end of the stationary end second fastener 303 facing away from the stationary end insulating pad 302. Specifically, both the stationary end first fastener 301 and the stationary end second fastener 303 are nuts. The stationary end reinforcing fastener 304 is a locking nut.

[0057] The end of the positioning rod 101 extending beyond the moving end clamping plate 4 is provided with a first moving end fastener 401, and a second moving end fastener 403 is also provided on the positioning rod 101. The moving end clamping plate 4 is positioned between the second moving end fastener 403 and the first moving end fastener 401, thereby fixing the moving end clamping plate 4. A moving end insulating pad 402 is provided on the inner side of the moving end clamping plate 4, and the moving end insulating pad 402 is positioned between the second moving end fastener 403 and the moving end clamping plate 4. Further, a moving end reinforcing fastener 404 is also provided on the positioning rod 101, and the moving end reinforcing fastener 404 is positioned at the end of the moving end fastener 403 facing away from the moving end insulating pad 402. Specifically, both the first moving end fastener 401 and the second moving end fastener 403 are nuts. The moving end reinforcing fastener 404 is a locking nut.

[0058] The two bushings 201 of the boom assembly 2 are respectively fitted onto the two rotating shafts 103.

[0059] Both the stationary end clamping plate 3 and the moving end clamping plate 4 have four through holes that match the positioning rod 101, and the four through holes on the stationary end clamping plate 3 and the moving end clamping plate 4 are arranged in a rectangular dot matrix. The four through holes on the stationary end clamping plate 3 or the four through holes on the moving end clamping plate 4 form the four corner points of a rectangle.

[0060] Furthermore, both the stationary end clamping plate 3 and the moving end clamping plate 4 are circular plates, and the four through holes on the stationary end clamping plate 3 and the four through holes on the moving end clamping plate 4 are arranged equidistantly along a ring.

[0061] Optionally, both the stationary end insulating pad 302 and the moving end insulating pad 402 are made of silicone rubber.

[0062] Optionally, the bushing 201 is made of H62 brass, and the reinforcing plate 202, the boom 203, and the hanger assembly 1 are all made of 316L stainless steel.

[0063] Example 2

[0064] In this embodiment, the silver-plated flip-type fixture for a vacuum interrupter is used by first covering the moving end of the vacuum interrupter 6 with a protective rubber sleeve and installing the moving end insulating pad 402. Then, the stationary end clamping plate 3 is removed, and the fixture of this invention is hoisted onto the vacuum interrupter 6 turnover car using the silver plating production line crane.

[0065] The tooling of the present invention extends from above the vacuum interrupter 6 (a stationary end clamping plate 3 is pre-fixed at the bottom of the vacuum interrupter 6 in the turnover vehicle as a tooling plate for the previous process), aligns the four positioning rods 101, passes through the moving end clamping plate 4, and is installed on the bottom tooling plate.

[0066] Tightening the stationary end first fastener 301, stationary end second fastener 303, and stationary end reinforcing fastener 304 completes the lower part fixation of the vacuum interrupter 6 within the hanger assembly 1.

[0067] Adjust the first fastener 401, the second fastener 403, and the reinforcing fastener 404 at the moving end to press the moving end clamping plate 7 against the vacuum interrupter 6.

[0068] The vacuum interrupter 6 is moved to the upper end of the electroplating line by vertical hoisting using an electroplating line crane. The directional locking part 5 is removed, and the vacuum interrupter 6 is rotated for the first time via the rotating shaft 103.

[0069] After standing upright, tighten the directional locking part 5, remove the bottom tooling plate of the vacuum interrupter 6, put the rubber sleeve on the stationary end of the vacuum interrupter 6, install the stationary end insulating pad 302, install the stationary end clamping plate 3, press the stationary end clamping plate 3, and then tighten the stationary end second fastener 303 and stationary end reinforcing fastener 304, and then tighten the stationary end first fastener 301. At this point, the installation of the vacuum interrupter 6 and the electroplating tooling is completed.

[0070] The vacuum interrupter 6 is lifted by a crane on the electroplating line. The moving end is electroplated first on the upper line. After the lower line returns to the upper line, the directional locking part 5 is loosened, the fixture is rotated 180° so that the stationary end of the vacuum interrupter 6 is upright and facing downwards. The directional locking part 5 is then tightened again, and the stationary end electroplating of the vacuum interrupter 6 can be completed on the upper line.

[0071] After the stationary end electroplating is completed, the electroplating fixture is flipped at the lower position so that the stationary end of the vacuum interrupter 6 is upright. First, the stationary end clamping plate 3 is removed, the stationary end insulating pad 302 is removed, and the electroplating protective sleeve is taken off. After installing the bottom fixture plate, the vacuum interrupter 6 is flipped again so that its moving end is upright. Then, the directional locking screw 9 is tightened. The vacuum interrupter 6 is transported to the base of the transfer cart using the electroplating crane. The bottom fixture plate at the bottom of the vacuum interrupter 6 is removed, and the electroplating fixture can be lifted away. Finally, the moving end insulating pad 402 and the electroplating protective sleeve of the vacuum interrupter 6 are removed, and the appearance of the vacuum interrupter 6 is processed. At this point, the electroplating process of the vacuum interrupter 6 is completed.
