Abstract
Description
Technical Field
[0001] This utility model relates to a current transformer assembly fixture, specifically a fusible tube silicone sleeve stretching assembly fixture. Background Technology
[0002] In products such as outdoor current transformers, silicone sleeves need to be installed on the casting body. For structures where the casting body extends into two fusible tubes, when the silicone sleeve is installed onto the casting body, if the two fusible tubes are tilted with a larger gap at the top and a smaller gap at the bottom, it is difficult to directly fit the corresponding fusible tube sleeve positions on the silicone sleeve onto the casting body. The existing installation method is generally to first fit one fusible tube sleeve onto one fusible tube, and then use a pry bar to pull the other end of the fusible tube sleeve to complete the fitting onto the other fusible tube. This operation is time-consuming and laborious, and poses a certain risk of damage to both the fusible tube and the fusible tube sleeve, affecting the subsequent usability of the current transformer. Summary of the Invention
[0003] This utility model provides a tubular silicone sleeve stretching assembly tool that is simple in structure, easy to operate, and can simultaneously install double-fusible tube sets of silicone sleeves, ensure that the fusible tube sleeves are not damaged, and improve the installation precision.
[0004] The technical solution adopted by this utility model is: a welding tube silicone sleeve stretching assembly tool, characterized in that: it includes a base and a liftable bracket, the base has two upper frames that are supported by two lifting brackets on both sides, a crossbeam is set between the two upper frames, an adjusting cylinder is horizontally set on the crossbeam, a fixed blocking rod is vertically set below one side of the adjusting cylinder on the crossbeam, a movable blocking rod is set below the other side of the adjusting cylinder and connected to the telescopic rod of the adjusting cylinder, and downward-facing air jet holes are set in the fixed blocking rod and the movable blocking rod, and a clean air compressed air supply system is connected to the air jet holes.
[0005] A tooling for stretching and assembling silicone sleeves for fusion tubes, characterized in that: it includes a base and a lifting bracket, with two upper frames supported by two lifting brackets on both sides of the base, a crossbeam between the two upper frames, an adjusting cylinder horizontally positioned at the center of the crossbeam, adjustable telescopic rods extending synchronously to both sides of the adjusting cylinder, and two movable baffles connected to the telescopic rods of the adjusting cylinder on both sides below the adjusting cylinder, with downward-facing air jet holes inside, and a clean air compressed air supply system connected to the air jet holes.
[0006] A guide beam, lower than the crossbeam, is also provided between the two upper frames, and the movable grid rod slides and is connected to the guide beam.
[0007] The clean air compressed air supply system includes a nitrogen storage tank and a booster pump, with the nitrogen storage tank connected to the jet nozzle via the booster pump.
[0008] The clean air compressed air supply system includes an air compressor and an air buffer tank. The air compressor is connected to the air buffer tank via a coarse filter, and the air buffer tank is connected to the jet port via a booster pump and a fine filter.
[0009] The fixed and movable guardrails are circular or elliptical.
[0010] The beneficial effects of this utility model are as follows: A casting body structure with two symmetrically inclined outward-facing molten tubes is installed on the base, so that the fixed guard rod on one side corresponds to the molten tube on the other side. The fixed guard rod and the movable guard rod are inserted into the upper openings of the two molten tubes of the silicone sleeve integral structure. By adjusting the telescopic rod of the cylinder, the movable guard rod is extended outward, aligning the molten tube corresponding to the movable guard rod with the molten tube on the other side. Then, the lifting bracket is controlled to move the crossbeam downward, fitting the two molten tubes of the silicone sleeve onto the two molten tubes. During assembly, a clean air compressed air supply system cleans the inside of the silicone sleeve and the upper surfaces of the molten tubes and casting body by air jets through the jet holes on the fixed and movable guard rods. This makes the assembly operation convenient and ensures that the assembly gaps are dust-free, ensuring stable performance of the current transformer's molten tubes. Using circular or elliptical guard rods effectively avoids damage to the upper openings of the molten tube sleeves, improving the assembly accuracy and current transformer performance.

[0013] The following explanation, in conjunction with the accompanying drawings, will provide further details.
[0014] Figure 1 , 2 As shown: A stretching assembly fixture for a silicone sleeve includes a base 1, a lifting bracket 2, an upper frame 3, a crossbeam 4, a guide beam 5, an adjusting cylinder 6, a telescopic rod 7, a fixed stop rod 8, a movable stop rod 9, a nitrogen storage tank 11, and a booster pump 12. The base 1 is supported by two lifting brackets 2 on both sides, which lift and lower the upper frame 3. A crossbeam 4 and a guide beam 5 are positioned between the two upper frames 3. An adjusting cylinder 6 is horizontally mounted on the crossbeam 4. A fixed stop rod 8 is vertically mounted below one side of the adjusting cylinder 6, and a movable stop rod 9 is mounted below the other side of the adjusting cylinder 6, connected to the telescopic rod 7 of the adjusting cylinder. The fixed stop rod 8 passes through the guide beam 5, and the movable stop rod 9 slides and guides through the guide beam 5. Downward-facing air jets 10 are provided inside the fixed stop rod 8 and the movable stop rod 9. Air is introduced into the air jets 10 from the nitrogen storage tank 11 via the booster pump 12.
[0015] When using, such as Figure 2The casting body 13 is placed and fixed on the base 1, so that the melt tube 14 on one side of the casting body 13 corresponds to the bottom of the fixed grid rod 8. The upper openings of the two melt tube sleeves 16 of the silicone sleeve 15 are respectively fitted onto the lower ends of the fixed grid rod 8 and the movable grid rod 9. The adjusting motor 6 is started, and the movable grid rod 9 is moved through the telescopic rod 7, while the silicone sleeve 15 is stretched so that the two silicone sleeves 15 correspond to the top of the two melt tubes 14 of the casting body 13. The lifting bracket 2 drives the crossbeam 4 and the guide beam 5 to descend synchronously through the upper frame 3, and the melt tube sleeves 16 of the silicone sleeve 15 are fitted onto the two melt tubes 14. At the same time as fitting, the booster pump is started to ensure that there is no dust in the fitting part and the gap through the air jet hole 10.
[0016] In this embodiment, the fixed and movable guard bars are preferably designed to be circular or elliptical.
[0017] In this embodiment, the structure of the lifting support 2 is not limited. In the prior art, the lifting support structure that drives the upper frame to rise and fall is a prior art.
[0018] In this embodiment, the clean air compressed air supply system is selected as a nitrogen system, but an air system can also be selected. The air system needs to be filtered by a coarse filter, buffered by a buffer tank, pressurized by a booster pump, and filtered by a fine filter in sequence.
[0019] Based on this embodiment, the adjusting cylinder can also be designed as a two-way cylinder, which simultaneously drives the two moving baffle rods to expand the silicone sleeve and the fusion tube sleeve outward.
