Technical Field
[0001] The utility model belongs to the technical field of mutual inductor manufacturing, and in particular relates to a compression shell assembly tool. Background Art
[0002] The transformer is provided with pins, but the pins are thin, the exposed pins are too long and the structural strength is low. Therefore, during storage and transportation, the exposed pins are often damaged and deformed, resulting in product quality problems. Therefore, a protective shell is usually used to protect the pins. The protective shell is provided with two groups of through holes for wrapping the pins, thereby avoiding exposure of the pins and forming protection.
[0003] At present, the protective shell and the transformer are generally fixed by plugging. The plugging process is usually manually operated by staff. It is necessary to align the plug rod of the protective shell with the slots on both sides of the transformer and press them to form a plug-in fixation. However, in actual operation, due to the small size of the transformer and the protective shell, it is difficult for staff to ensure that the pins are accurately aligned with the through holes of the protective shell. Pins are often damaged during the installation of the protective shell, and manual operation has low production efficiency, which is not suitable for large-scale operations. Utility Model Content
[0004] In order to solve the problems existing in the above-mentioned prior art, the utility model provides a compression shell assembly tool, which only requires the staff to fill the mutual inductor and the protective shell into the movable block and the fixed block and start the telescopic mechanism to achieve high-precision matching of the mutual inductor and the protective shell, avoid damage to the pins during the installation and rotation process, and improve production efficiency, which is suitable for large-scale operations.
[0005] The specific technical solution adopted by the utility model is:
[0006] A compression shell assembly tool comprises a base and a fixed block fixedly connected to the base, the fixed block is provided with a first groove for fixing a protective shell, the base is also provided with a movable block and a telescopic mechanism, the movable block is provided with a second groove for fixing a mutual inductor, the mutual inductor in the second groove matches the position of the protective shell in the first groove, the movable block is suspended above the fixed block by means of the telescopic mechanism and has the freedom to approach and move away from the fixed block, and the mutual inductor in the movable block approaches the protective shell by means of the telescopic mechanism and forms a plug-in match.
[0007] The telescopic mechanism includes a telescopic cylinder, a fixed plate and a sliding seat. The fixed plate is cantilevered and fixed on the base by means of a limiting slide rod. The telescopic cylinder is fixedly connected to the fixed plate. The slide rod is fitted with the limiting slide rod and forms a sliding degree of freedom by means of the telescopic end of the telescopic cylinder and the limiting slide rod. The movable block is fixedly connected to the slide seat.
[0008] The telescopic mechanism also includes a buffer spring, which is located between the slide seat and the base, and the buffer spring is sleeved with the limiting slide rod.
[0009] The sliding seat is in a groove-shaped structure matching the movable block, the notch of the sliding seat faces one side of the fixed seat, the movable block is detachably fixedly connected to the sliding seat by means of bolts, and a groove-shaped fixed seat is also provided on the base, and the fixed block is detachably plug-in fixed to the base by means of the fixed seat.
[0010] A limiting block is arranged below the slide seat, and a limiting groove matching the concave and convex of the limiting block is arranged on the side wall of the fixed seat. The fixed seat hinders the movement of the slide seat and forms a limit by means of the limiting block.
[0011] The mutual inductor has the same width as the protective shell, the width of the first groove is the width of the protective shell*n, and the width of the second groove is the width of the mutual inductor*n, where n is a positive integer.
[0012] The beneficial effects of the utility model are:
[0013] The utility model provides a shell compression assembly tool. When in use, a staff first fixes the mutual inductor and the protective shell to the movable block and the fixed block respectively. Since the edges of the first groove and the second groove are flush and the width of the mutual inductor and the protective shell are the same, the insertion rod of the protective shell in the first groove is just aligned with the slot of the mutual inductor in the second groove. At the same time, the pin of the mutual inductor is just aligned with the through hole of the protective shell. Then, the telescopic mechanism is started to make the movable block equipped with the mutual inductor slide down. The sliding movable block forms a pressing force to complete the plug-in connection between the mutual inductor and the protective shell. Finally, the telescopic mechanism is started in the opposite direction to pull up the interconnected mutual inductor and the protective shell together. The staff can complete the disassembly.
[0014] The tooling only requires the staff to load the mutual inductor and the protective shell into the movable block and the fixed block to achieve high-precision matching of the mutual inductor and the protective shell, thereby avoiding damage to the pins during the installation and rotation process. At the same time, the first groove and the second groove can be filled with a plurality of arrays of protective shells and mutual inductors respectively, and adjacent mutual inductors or adjacent protective shells are closely arranged. The telescopic mechanism can complete the plug-in installation of multiple sets of mutual inductors and protective shells each time it is lowered and pressed, thereby improving production efficiency and being suitable for large-scale operations.

[0020] The utility model is further described below in conjunction with the accompanying drawings and specific embodiments:
[0021] Specific embodiments, such as Figure 1-4 As shown, the utility model provides a compression shell assembly tool, including a base 1 and a fixed block 2 fixedly connected to the base 1, the fixed block 2 is provided with a first groove 3 for fixing a protective shell, the base 1 is also provided with a movable block 4 and a telescopic mechanism, the movable block 4 is provided with a second groove 5 for fixing a mutual inductor, the mutual inductor in the second groove 5 matches the position of the protective shell in the first groove 3, the movable block 4 is suspended above the fixed block 2 by means of the telescopic mechanism and has the freedom to approach and move away from the fixed block 2, and the mutual inductor in the movable block 4 is approached to the protective shell by means of the telescopic mechanism and forms a plug-in match.
[0022] Due to the small size of the mutual inductor and the protective shell, it is difficult for workers to ensure that the pins are accurately aligned with the through holes of the protective shell. Pin damage often occurs during the installation of the protective shell. In addition, manual operation has low production efficiency and high labor costs, which is not suitable for large-scale operations.
[0023] Therefore, the utility model provides a shell compression assembly tool. When in use, the staff first fixes the mutual inductor and the protective shell to the movable block 4 and the fixed block 2 respectively. Since the edges of the first groove 3 and the second groove 5 are flush and the mutual inductor and the protective shell have the same width, the insertion rod of the protective shell in the first groove 3 is just aligned with the slot of the mutual inductor in the second groove 5, and the pins of the mutual inductor are just aligned with the through holes of the protective shell. Then, the telescopic mechanism is started to make the movable block 4 equipped with the mutual inductor slide down, and the sliding movable block 4 forms a pressing force to complete the connection between the mutual inductor and the protective shell. Finally, the telescopic mechanism is started in the opposite direction to pull up the interconnected mutual inductor and the protective shell together, and the staff can complete the disassembly.
[0024] The tooling only requires the staff to fill the mutual inductor and the protective shell into the movable block 4 and the fixed block 2 to achieve high-precision matching of the mutual inductor and the protective shell, thereby avoiding damage to the pins during the installation process. At the same time, the first groove 3 and the second groove 5 can be filled with arrays of protective shells and mutual inductors respectively, and adjacent mutual inductors or adjacent protective shells are closely arranged. The telescopic mechanism can complete the plug-in installation of multiple sets of mutual inductors and protective shells each time it is lowered and pressed, which improves production efficiency and is suitable for large-scale operations.
[0025] like Figure 1-3 As shown, the telescopic mechanism includes a telescopic cylinder 6, a fixed plate 7 and a slide 8, the fixed plate 7 is cantilevered and fixed on the base 1 by means of a limit slide 9, the telescopic cylinder 6 is fixedly connected to the fixed plate 7, the slide 8 is fitted with the limit slide 9 and forms a sliding degree of freedom with the help of the telescopic end of the telescopic cylinder 6 and the limit slide 9, the movable block 4 is fixedly connected to the slide 8, and the movable seat block is driven by the telescopic end of the telescopic cylinder 6 to form an up and down lift, wherein the telescopic cylinder 6 pre-sets the telescopic distance, so that the mutual inductor and the protective shell are just plugged in when the telescopic cylinder 6 is extended to the farthest end, and the plug-in rod end of the protective shell is hook-shaped to ensure that the protective shell can be pulled up with the movement of the mutual inductor after the plug-in installation is completed.
[0026] like Figure 1-3 As shown, the telescopic mechanism also includes a buffer spring 10, which is located between the slide 8 and the base 1. The buffer spring 10 is sleeved with the limiting slide rod 9. By setting the buffer spring 10, it can be prevented that the movable block 4 is too fast during the descent process, resulting in severe collision and damage between the mutual inductor and the protective shell.
[0027] like Figure 1-3 As shown, the slide seat 8 is in a groove-shaped structure matching the movable block 4, and the notch of the slide seat 8 faces the side of the fixed seat 11. The movable block 4 is detachably fixedly connected to the slide seat 8 by means of bolts. The base 1 is also provided with a groove-shaped fixed seat 11. The fixed block 2 is detachably plugged and fixed to the base 1 by means of the fixed seat 11. The groove size of the movable block 4 and the fixed block 2 will be deformed during long-term use, and gaps will appear on both sides of the mutual inductor and the protective shell in the groove and will shake left and right, resulting in misalignment of the pins and the through holes of the protective shell. Therefore, the movable block 4 and the fixed block 2 need to be replaced on time, and the detachable connection method facilitates the replacement of the movable block 4 and the fixed block 2.
[0028] like Figure 3-4As shown, a limit block 12 is arranged under the slide 8, and a limit groove 13 matching the limit block 12 is arranged on the side wall of the fixed seat 11. The fixed seat 11 hinders the movement of the slide 8 and forms a limit with the help of the limit block 12. The slide 8 is limited by the limit block 12 to prevent the telescopic cylinder 6 from sliding down too much and causing extrusion deformation between the mutual inductor and the protective shell.
[0029] like Figure 1-2 As shown, the mutual inductor and the protective shell have the same width, the width of the first groove 3 is the width of the protective shell*n, the width of the second groove 5 is the width of the mutual inductor*n, and n is a positive integer. In order to ensure that the mutual inductor and the protective shell are exactly aligned, the first groove 3 and the second groove 5 need to be exactly filled when filling the mutual inductor and the protective shell, and there are no gaps on both sides of the mutual inductor and the protective shell to ensure that the mutual inductor and the protective shell will not shake left and right during the assembly process, thereby avoiding misalignment between the pins of the mutual inductor and the through holes of the protective shell.
