Description

Technical Field

[0001] The utility model belongs to the technical field of solid-sealed poles, and in particular relates to a solid-sealed pole positioning device. Background Art

[0002] The sealed pole is formed by embedding the vacuum interrupter and the conductive parts related to the circuit breaker into easily solidified solid insulating materials such as epoxy resin or thermoplastic materials, so that the entire circuit breaker pole becomes an integral component.

[0003] When the sealed pole is being processed and produced, it needs to be positioned and fixed to facilitate various processing operations on the sealed pole.

[0004] However, there are some problems with the existing technology: when in use, the existing positioning devices are clamped and fixed from the outside, which cannot achieve centering and fixing of the sealed pole, and easily cause errors in the processing of the sealed pole. Therefore, we propose a sealed pole positioning device. Utility Model Content

[0005] In view of the problems existing in the prior art, the purpose of the present invention is to provide a sealed pole positioning device, which improves the accuracy of the sealed pole during positioning and improves the precision of the processing operation by centering and fixing the sealed pole from the inside.

[0024] In order to further understand the content, features and effects of the present invention, the following embodiments are given as examples and described in detail with reference to the accompanying drawings.

[0025] like Figures 1 to 6 As shown, an embodiment of the present invention provides a sealed pole positioning device, comprising a positioning base plate 1, a limiting cylinder 2 fixedly mounted on the positioning base plate 1, a lifting and locking mechanism 4 installed inside the limiting cylinder 2, a push plate 6 movably provided at the bottom of the limiting cylinder 2 for pushing the lifting and locking mechanism 4, and an upper surface of the push plate 6 is configured as an inclined surface;

[0026] The lifting and locking mechanism 4 includes a lifting rod 401 arranged inside the limiting cylinder 2. The bottom of the lifting rod 401 is provided with an inclined surface adapted to the push plate 6. Four pushing crank rods 403 are movably installed on the upper end of the lifting rod 401. The four pushing crank rods 403 are commonly penetrated by a same elastic leather strip 405 for folding. The lower parts of the four pushing crank rods 403 are movably connected with a pull rod 406 for adjusting the angle. The other end of the pull rod 406 is movably connected to the top of the limiting cylinder 2.

[0027] In this embodiment, preferably, four first mounting grooves 402 are formed on the upper edge of the lifting rod 401, and one end of the four pushing crank rods 403 is movably connected to the inside of the four first mounting grooves 402 through pins;

[0028] It should be noted that the setting of the first mounting groove 402 facilitates the movable mounting of the pushing crank rod 403, so that when the lifting rod 401 is raised or lowered, the pushing crank rod 403 facilitates angle adjustment, thereby facilitating fixed support of the inner wall of the sealed pole.

[0029] In this embodiment, preferably, a fitting block 404 is movably mounted on the end of the pushing crank rod 403 via a pin, and the fitting block 404 is an arc-shaped block, and a rubber pad with anti-slip stripes is adhered to the outer surface of the fitting block 404;

[0030] It should be noted that the setting of the fitting block 404 facilitates close fitting on the inner wall of the solid sealing pole, and the rubber pad can improve the friction and reduce the damage to the inner wall of the solid sealing pole, and the movable connection of the fitting block 404 facilitates close fitting on the inner wall of the solid sealing pole at all times when the angle of the pushing crank rod 403 is adjusted.

[0031] In the embodiment, preferably, the upper surface of the limiting cylinder 2 is fixedly provided with four first connecting blocks 407, the lower part of the pushing crank rod 403 is fixedly provided with a second connecting block 409, and the first connecting block 407 and the second connecting block 409 are correspondingly arranged; the two ends of the pull rod 406 are respectively provided with a first connecting head 408 and a second connecting head 410, the first connecting head 408 is movably connected with the first connecting block 407 through a pin shaft, and the second connecting head 410 is movably connected with the second connecting block 409 through a pin shaft.

[0032] It should be noted that the pull rod 406 is movably connected with the first connecting block 407 and the second connecting block 409 through the first connecting head 408 and the second connecting head 410 at the two ends, so that the pull rod 406 is facilitated to rotate when the angle of the pushing crank rod 403 is adjusted, and the movement of the pull rod 406 is prevented.

[0033] In the embodiment, preferably, the outer side of the upper end of the limiting cylinder 2 is welded with a supporting ring 3 for supporting the solid sealing pole, a servo cylinder 5 for pushing the push plate 6 is fixedly installed on the positioning base plate 1, and one end of the push plate 6 is fixedly connected with the output end of the servo cylinder 5.

[0034] It should be noted that when the solid sealing pole is placed, the bottom of the solid sealing pole is supported by the supporting ring 3, so that the balance stability of the solid sealing pole is maintained, and the servo cylinder 5 is arranged to push the push plate 6.

[0035] In the embodiment, preferably, the bottom of the limiting cylinder 2 is provided with a moving groove 7 for sliding of the push plate 6, the center of the limiting cylinder 2 is provided with a through hole 8 for lifting adjustment of the lifting rod 401, and the bottom surface of the lifting rod 401 is in sliding contact with the upper surface of the push plate 6.

[0036] It should be noted that the moving groove 7 is arranged to facilitate the pushing of the push plate 6, and the through hole 8 is arranged to facilitate the limiting of the lifting rod 401, so that the push plate 6 and the lifting rod 401 are facilitated to contact in the interior of the limiting cylinder 2, and the push plate 6 can lift and adjust the lifting rod 401.

[0037] The specific operation process of the utility model is as follows:

[0038] The positioning substrate 1 is installed on the operating table or the conveyor belt of the assembly line, and the sealed pole that needs to be processed is placed on the support ring 3, and the lifting locking mechanism 4 is inside the sealed pole. At this time, the servo electric cylinder 5 is started so that the servo electric cylinder 5 can push the push plate 6, and the inclined surface of the push plate 6 is in contact with the inclined surface of the bottom of the lifting rod 401. When the push plate 6 pushes, the lifting rod 401 can be lifted up. When the lifting rod 401 is lifted, one end of the pushing crank rod 403 at the upper end of the lifting rod 401 moves upward, and the other end of the pushing crank rod 403 moves downward and outward under the action of the pull rod 406, so that the fitting block 404 can fit tightly against the inner wall of the sealed pole, thereby realizing centering and fixing of the sealed pole, which is convenient for subsequent precise processing operations.

[0039] After the processing is completed, the servo electric cylinder 5 is driven to pull back the push plate 6, so that the lifting rod 401 descends. When the lifting rod 401 descends, one end of the pushing crank rod 403 moves downward. Under the action of the elastic leather strip 405, the four pushing crank rods 403 are retracted inward, so that the fitting block 404 can loosen the centering fixation of the sealed pole, and then the sealed pole is removed to complete the processing operation.

[0040] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
