Description

Technical Field

[0001] This invention relates to the field of drop-out fuse technology, and more particularly to a device for assembling a fuse carrier in a drop-out fuse. Background Technology

[0002] A drop-out fuse is a common short-circuit protection device used in power distribution line branches and distribution transformers. It has a clearly defined breaking point and also functions as a disconnecting switch. Its core component, the fuse tube, consists of an inner arc-extinguishing tube and an outer phenolic paper tube or epoxy fiberglass cloth tube. During normal operation, the fuse wire tension keeps the fuse tube closed. In case of a fault, the fuse wire melts, the arc-extinguishing tube decomposes the gas to extinguish the arc, and the fuse tube drops to form the breaking position. The assembly process of the fuse tube is roughly as follows: riveting the lower fitting to the bottom of the fuse tube, riveting the upper fitting with hooks to the top of the fuse tube, screwing the conductive copper cap onto the upper fitting, and riveting the stress-bearing bracket onto the lower fitting; after assembly, the dimensions of the entire fuse tube are measured. Regarding the measurement of assembled fuse tubes, a standardized fuse carrier testing fixture is disclosed in publication number CN219359272U. This fixture includes a separable scale and a testing mechanism. The scale comprises a tube body with an arc-shaped wall at one end. A rotating shaft is radially protruding from the outer circumference of the tube body on the side opposite to the arc-shaped wall. The testing mechanism includes a base with a support on one side. The support has a mounting groove at the end opposite to the base for embedding one end of the tube body. The surrounding wall of the mounting groove has a rotating groove for mounting the rotating shaft or the lower moving contact rod of the fuse carrier. A support block is located in the middle of the base, with a through groove at the end opposite to the base for limiting the tube body. An adjusting block is located on the base on the side of the support block opposite to the support. A dial indicator is mounted on the adjusting block, with its measuring axis abutting against the arc-shaped wall or the arc surface of the conductive cap. This prior art allows for precise measurement of assembled fuse tubes.

[0003] Regarding the assembly of the fuse tube, a search revealed an automatic riveting device for drop parts disclosed in announcement number CN222720319U. The device includes: a workbench containing a mold, the mold having a first fixed cavity that mates with the fuse tube and the pull ring sleeve, and a second fixed cavity that mates with the fuse tube and the trunnion sleeve; a recycling box is provided below the workbench; and a riveting device punches pins to achieve the connection and fixation of the fuse tube and the pull ring sleeve, and the connection and fixation of the fuse tube and the trunnion sleeve.

[0004] When operating the aforementioned equipment to perform the process of "riveting the lower pipe to the bottom of the molten tube, riveting the upper pipe with hook ring to the top of the molten tube, screwing the conductive copper cap onto the upper pipe, and riveting the hanging stress bracket onto the lower pipe," the two riveting processes of "riveting the lower pipe to the bottom of the molten tube and riveting the upper pipe with hook ring to the top of the molten tube" can be completed on the same riveting machine and support mold. However, the riveting process of "riveting the hanging stress bracket onto the lower pipe" needs to be completed on a different riveting machine and support mold. This results in the overall riveting process being fragmented, requiring frequent changes to different riveting machines and support molds, making continuous operation impossible, and leading to low processing efficiency.

A transparent window panel 3 and a first bevel gear 40 are fixed to the outer side of each first rotating shaft 39. In order to facilitate opening or closing the transparent window panel 3 at any time, a bearing top seat 38 is fixed to the center inside the support frame 2. A dual-axis motor 41 is fixed to the upper end of the bearing top seat 38 and located inside the I-beam top frame 37. A second rotating shaft 42 is fixed to each of the two output ends of the dual-axis motor 41. The end of each second rotating shaft 42 away from the dual-axis motor 41 passes through the I-beam top frame 37 and is fixed with a second bevel gear 43. The second rotating shaft 42 is rotatably connected to the I-beam top frame 37. The two second bevel gears 43 are respectively meshed with the two first bevel gears 40. Limiting guide rods 45 are fixed at the four corners of the inner side of the bearing top seat 38. A screw 44 is fixed at the center of the inner side of the bearing top seat 38. A lifting frame 46 is slidably connected between the four limiting guide rods 45. An internally threaded cylinder 47 is rotatably connected inside the lifting frame 46 and outside the screw 44. The inner side of the internally threaded cylinder 47 is threaded to the screw 44. A fourth spur gear 48 is fixed outside the internally threaded cylinder 47 and inside the lifting frame 46. A third motor 49 is fixed on the outside. A fifth spur gear 50 and a worm gear 51 are fixed on the output end of the third motor 49. The fifth spur gear 50 is meshed with the fourth spur gear 48. A third rotating shaft 52 is rotatably connected to the inside of the lifting frame 46. A first riveting machine 30 and a second riveting machine 31 are respectively installed on the outside of both ends of the third rotating shaft 52. A worm wheel 53 is fixed on the outside of the third rotating shaft 52 and between the first riveting machine 30 and the second riveting machine 31. The worm wheel 53 is meshed with the worm gear 51. The first riveting machine 30 is located at the upper end of the support plate 13, and the second riveting machine 31 is located at the upper end of the second support mold 28; When the dual-axis motor 41 is started, driving the two second bevel gears 43 to rotate, the meshing of the second bevel gears 43 with the first bevel gear 40 drives the two first rotating shafts 39 to rotate, thereby causing the two transparent window panels 3 to flip and open around the first rotating shafts 39. At this time, the third motor 49 is started, driving the fifth spur gear 50 and the worm gear 51 to rotate. The meshing of the fifth spur gear 50 with the fourth spur gear 48 drives the internal threaded cylinder 47 to rotate. The threaded connection between the internal threaded cylinder 47 and the screw 44, combined with the guiding and limiting of the limiting guide rod 45, drives the lifting frame 46 to move downward. At the same time, the meshing of the worm gear 51 with the worm wheel 53 drives the third rotating shaft 52 to rotate, thereby enabling the first riveting machine 30 and the second riveting machine 31 to flip and tilt around the third rotating shaft 52. Figure 2 As shown, this allows staff to easily access the inside of the support frame 2 through the open transparent window 3 to inspect and replace the pressure heads of the first riveting machine 30 and the second riveting machine 31.

[0019] Working principle: First, workers are set up on the outside of the first controller 6 and the second controller 7 respectively. The workers on the outside of the first controller 6 place the fuse tube body 33 on the hollow support platform 18 at the upper end of the support plate 13 near the first controller 6. The support components at the upper end of the hollow support platform 18 are used to clamp, limit, support and fix the fuse tube body 33. At this time, the top or bottom of the fuse tube body 33 faces the workers, so that the workers can easily connect the upper pipe body 34 or the lower pipe body 35 to the fuse tube body 33. Then, the first riveting machine 30 is operated to rivet and fix it. After one end of the fuse tube body 33 is assembled, the electric telescopic rod 21 is started to control the fuse tube body 33 located inside the pneumatic clamp 24 to rise. At the same time, the second motor 26 is started to drive the third spur gear 27 to rotate. The meshing of the third spur gear 27 and the second spur gear 25 drives the electric telescopic rod 21 to rotate, thereby driving the fuse tube body 33 to turn so that the other end of the fuse tube body 33 faces the workers, so as to facilitate reassembly. After the upper pipe fitting body 34 and the lower pipe fitting body 35 are assembled with the fuse tube body 33, the first motor 16 is started to drive the first spur gear 17 to rotate. The meshing of the first spur gear 17 with the internal gear ring 15 drives the support plate 13 to rotate around the support shaft 14, so that the fuse tube body 33, which is equipped with the upper pipe fitting body 34 and the lower pipe fitting body 35, moves towards the second controller 7. This makes it easier for another worker to remove the fuse tube body 33 and use the second support mold 28, the second riveting machine 31, the screwing positioning frame 29, and the screwing device 32 to assemble the fuse tube body 33 with the stress support body 36 and the conductive copper cap. Meanwhile, the worker located outside the first controller 6 can assemble a new fuse tube body 33 on the upper end of another hollow support 18, effectively ensuring the continuity of the assembly process and thus effectively improving processing efficiency.
