Abstract
Description
Technical Field
[0001] The utility model relates to the field of solid-sealed pole production, in particular to a solid-sealed pole die head pick-up and placement tool. Background Art
[0002] The solid-sealed pole is an independent component that encapsulates the vacuum interrupter, conductive connection and / or terminal with solid insulating materials. Specifically, it is to embed the vacuum interrupter (Vacuuminterruptor) and the related conductive parts of the circuit breaker (Circuit-breaker) into easily solidified solid insulating materials such as epoxy resin or thermoplastic materials to form a pole, making the entire circuit breaker pole an integral component.
[0003] The sealed pole has a simple structure and few detachable parts, which greatly improves the reliability of the circuit breaker. Compared with the traditional assembled pole, the number of parts of the sealed pole is greatly reduced, the conductor overlap surface is reduced from 6 groups to 3 groups, and the connecting bolts are reduced from 8 to 1-3. And it has extremely high insulation capacity. The sealed pole converts surface insulation into volume insulation. Compared with air insulation, it reduces the impact of the environment and greatly improves the insulation strength. This reduces the size of the circuit breaker and is conducive to the miniaturization of the switch cabinet.
[0004] The mainstream casting process of solid-sealed poles in the market is usually the APG casting process, which is to thermoform the epoxy curing material through the mold, inject the epoxy curing material into the mold at a certain injection pressure and maintain the pressure, and solidify and demold after the process time is reached, and the product is demolded and taken out. During the casting process, the temperature of the die head is very high. At the same time, during the process of picking and placing, it is necessary to prevent the collision between the die head and the lower core plate to avoid damage to the umbrella skirt structure of the pole cavity. Manual picking and placing requires rapid positioning and accurate picking and placing. Usually, workers need to wear multiple pairs of gloves to prevent burns, but this correspondingly reduces the flexibility of the workers' hands and has a greater impact on the workers' picking and placing accuracy.

[0032] Example
[0033] Please refer to Figure 1-3 As shown, this embodiment provides a tool for picking up and placing a solid-sealed pole die head, which is used to clamp the solid-sealed pole die head. The solid-sealed pole die head is cylindrical, and a plurality of outer annular surfaces arranged in sequence are arranged on the outside of the solid-sealed pole die head. Specifically, the tool for picking up and placing the solid-sealed pole die head includes a first clamping arm 1 and a second clamping arm 2. The middle parts of the first clamping arm 1 and the second clamping arm 2 are both provided with an arc clamping portion 101 protruding outward. The two arc clamping portions 101 enclose a clamping space 103. The clamping space 103 is for the solid-sealed pole die head to pass through, so as to make way for the solid-sealed pole die head. The two ends of the arc clamping portion 101 are provided with gripping plates 102 extending outward. The gripping plates 102 are for workers' hands to grip, so that there is a distance between the hands and the die head, thereby reducing the influence of the die head temperature on the workers' hands.
[0034] Please refer to Figure 1 and Figure 2 As shown, at least one positioning block 3 is fixed on the inner side of the arc clamping part 101, and the inner side surface of the positioning block 3 is a first arc surface 302. The first arc surfaces 302 of the two positioning blocks 3 are concentric with the solid-sealed pole die head; at least one outwardly protruding thread 301 is provided on the first arc surface 302, and the thread 301 and the bottom surface of the outer ring surface of the solid-sealed pole die head are in contact with each other. The two positioning blocks 3 position the solid-sealed pole die head from both sides, and the thread 301 supports the outer ring surface of the fixed pole to ensure that the first clamping arm 1 and the second clamping arm 2 have a good clamping effect on the solid-sealed pole die head.
[0035] A centering block 4 is fixed on the inner side surface of the arc clamping portion 101, and the inner side surface of the centering block 4 is a second arc surface 401. The second arc surface 401 and the first arc surface 302 are concentric and have equal radii. The centering block 4 pushes the sealed pole die head from both sides to ensure the accuracy of the central axis position of the sealed pole die head, thereby assisting workers to accurately take and place the sealed pole die head. In this embodiment, the number of centering blocks 4 fixed on the inner side surfaces of the arc clamping portion 101 of the first clamping arm 1 and the second clamping arm 2 is two, and the two centering blocks 4 are respectively located on both sides of the positioning block 3. The centering block 4 pushes and centers the sealed pole die head from multiple directions to further ensure the accuracy of the position of the sealed pole die head.
[0036] Furthermore, the number of the threads 301 is at least two, and the adjacent threads 301 are respectively in contact with the top surface and the bottom surface of the outer ring surface of the solid-sealed pole die head. At least two threads 301 position the solid-sealed pole die head from the top surface and the bottom surface, effectively improving the positioning effect of the positioning block 3. In this embodiment, the number of the threads 301 is two, and similarly, the number of the threads 301 can also be three or more.
[0037] In this embodiment, the first clamp arm 1 and the second clamp arm 2 are both metal clamp arms, which effectively improve the structural strength of the first clamp arm 1 and the second clamp arm 2 to avoid bending of the first clamp arm 1 and the second clamp arm 2 during the picking and placing process, thereby affecting the accuracy of picking and placing.
[0038] Please refer to Figure 2 and Figure 3 As shown, a rotating connection piece is fixed between the grab plate 102 at one end of the first clamp arm 1 and the second clamp arm 2, and the rotating connection piece enables the other ends of the first clamp arm 1 and the second clamp arm 2 to flip outward or approach each other, so as to achieve the sleeve of the solid-sealed pole die. In this embodiment, the rotating connection piece is a hinge 5, and the hinge axis 501 of the hinge 5 protrudes from the end of the grab plate 102. The hinge 5 enables the other ends of the first clamp arm 1 and the second clamp arm 2 to flip outward or approach each other, so as to achieve the sleeve of the solid-sealed pole die. The same rotating connection piece can be other connection structures that can achieve the first clamp arm 1 and the second clamp arm 2 to flip outward or approach each other. The hinge axis 501 of the hinge 5 protrudes from the end of the gripping plate 102, so that the first clamp arm 1 and the second clamp arm 2 have a larger opening angle, which satisfies the need to directly take the large-diameter solid-sealed pole die head from both sides, and avoids the need to move the solid-sealed pole die head in the length direction during the installation process due to the small opening angle, which easily collides with the outer annular surface of the solid-sealed pole die head. Similarly, during use, a rotating connector may not be provided between the gripping plates 102 at one end of the first clamp arm 1 and the second clamp arm 2, and the first clamp arm 1 and the second clamp arm 2 can be accurately taken by holding the hand to ensure that the solid-sealed pole die head can be taken.
[0039] The positioning block 3 is a Teflon positioning block 3 or an aluminum positioning block 3. In the present embodiment, the positioning block 3 is a Teflon positioning block 3; similarly, the positioning block 3 can also be an aluminum positioning block 3. The centering block 4 is a Teflon centering block 4 or an aluminum centering block 4. In the present embodiment, the centering block 4 is a Teflon centering block 4; similarly, the centering block 4 can also be an aluminum centering block 4. The hardness of the Teflon positioning block 3, the aluminum positioning block 3, the Teflon centering block 4 and the aluminum centering block 4 is relatively low, so as to avoid damage to the solid-sealed pole die head during the process of taking and placing. Similarly, the positioning block 3 can also be a positioning block 3 made of other materials, such as a metal positioning block 3.
[0040] The above is only a preferred specific implementation of the utility model, but the protection scope of the utility model is not limited thereto. Any changes or substitutions that can be easily thought of by a person skilled in the art within the technical scope disclosed by the utility model should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model should be based on the protection scope of the claims.
