[0002] The pins of the secondary wire of the transformer are relatively 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 pin shell is usually used to protect the pins. Two sets of through holes are provided on the protective shell to wrap the pins, thereby avoiding exposure of the pins and forming protection.
[0003] At present, the pin shell and the transformer are generally fixed by plugging. The plugging process is usually manually operated by staff. The pins of the transformer need to be aligned with the through holes of the pin shell and pressed to form a plug-in fixation. However, in actual operation, due to the small size of the transformer and the pin shell, it is difficult for staff to ensure that the pins are accurately aligned with the through holes of the pin shell. Pin breakage often occurs during the installation of the needle shell, and manual operation has low production efficiency and is not suitable for large-scale operations. Utility Model Content

DETAILED DESCRIPTION
[0022] The utility model is further described below in conjunction with the accompanying drawings and specific embodiments:
[0023] Specific embodiments, such as Figure 1-4 As shown, the utility model provides a transformer secondary line pressure needle shell tooling, including a base 1 and a sliding mechanism and a fixed seat 2 arranged on the base 1, the fixed seat 2 is provided with a second groove 3 for the transformer 18 to be plugged and fixed, the sliding mechanism includes a slide rail 4, a slide seat 5 and a driving device, the slide seat 5 has the freedom to move along the slide rail 4 with the help of the driving device, the slide seat 5 is provided with a first groove 6 for the needle shell 19 to be plugged and fixed, the through hole of the needle shell 19 in the first groove 6 matches the pin position of the transformer 18 in the second groove 3, the driving device includes a driving wheel 7 and a driving block 8 matching the slide rail 4, the driving wheel 7 is eccentrically hinged with the base 1 with the help of the hinge frame 17, the driving block 8 is in contact with the driving wheel 7 and has the freedom to move along the slide rail 4 with the help of the eccentric rotation of the driving wheel 7, and the slide rail 4 forms a sliding freedom with the slide rail 4 with the help of the movement of the driving block 8.
[0024] Since the mutual inductor 18 and the needle shell 19 are small in size, it is difficult for the staff to ensure that the pins are accurately aligned with the through holes of the needle shell 19. Pin breakage often occurs during the installation of the needle shell 19, and manual operation has low production efficiency and is not suitable for mass operation.
[0025] Therefore, the utility model provides a transformer secondary line pressure needle shell tooling, wherein both sides of the first groove 6 and the second groove 3 are open. When in use, the transformer 18 is first fixed to the second groove 3, with the pins of the transformer 18 facing the slide 5, and then the needle shell 19 is fixed to the first groove 6. Since the width of the first groove 6 is equal to that of the second groove 3, and the edges of the first groove 6 and the second groove 3 are flush and the mutual inductor 18 and the needle shell 19 are the same width, when the first groove 6 and the second groove 3 are filled with the mutual inductor, the mutual inductor 18 and the needle shell 19 are filled with the mutual inductor 18. After the transformer 18 and the needle shell 19 are inserted, the pins of the whole row of mutual inductors 18 are just aligned with the through holes of the whole row of needle shells 19, and then the driving wheel 7 is rotated. Since the driving wheel 7 is an eccentric wheel, the driving wheel 7 will gradually move to the side of the driving block 8 and push the driving block 8 and the slide 5 to move toward the fixed seat 2. The needle shell 19 approaches the pins of the mutual inductor 18 with the slide 5 and is plugged and fixed with the mutual inductor 18 with the help of the push of the slide 5. Finally, the connected mutual inductor 18 and the needle shell 19 can be taken out along the sides of the first groove 6 and the second groove 3.
[0026] The tool only requires the staff to fill the mutual inductor 18 and the needle shell 19 into the fixed seat 2 and the slide seat 5 to achieve high-precision matching of the pins of the mutual inductor 18 and the needle shell 19, thereby avoiding damage to the pins of the mutual inductor 18 during the installation process. At the same time, the first groove 6 and the second groove 3 can be filled with a plurality of arrays of needle shells 19 and mutual inductors 18 respectively, and adjacent mutual inductors 18 or adjacent needle shells 19 are closely arranged. Each push of the slide seat 5 can complete the installation and fixation of multiple groups of mutual inductors 18 and needle shells 19, thereby improving production efficiency and being suitable for large-scale operations.
[0027] like Figure 5-6 As shown, the needle shell 19 in the utility model is a block structure, and the needle shell 19 is provided with two groups of through holes along the length direction for the pins of the mutual inductor 18 to pass through, and the two sides of the needle shell 19 are provided with fixing grooves 20 for the connection end of the mutual inductor 18 to be plugged and fixed, and the end of the needle shell 19 close to the mutual inductor 18 is provided with a buckle 21, and the end of the connection end of the mutual inductor 18 is provided with a slot 22 matching the buckle 21, wherein the needle shell 19 is made of plastic material and has a certain deformation ability. When the mutual inductor 1 When the connecting end of 8 is inserted into the fixing groove 20 of the needle shell 19, the buckle 21 will first contact the connecting end of the mutual inductor 18 and deform and lift up. When the connecting end of the mutual inductor 18 is fully inserted into the fixing groove 20, the buckle 21 will return to its original state and embed into the slot 22. The cooperation between the fixing groove 20 and the mutual inductor 18 forms a limit in the vertical direction, and the cooperation between the buckle 21 and the slot 22 forms a limit in the horizontal direction. The above structure can ensure that the mutual inductor 18 and the needle shell 19 are stably connected.
[0028] like Figure 1-4As shown, the driving device also includes a driven wheel 9, which is hinged to the driving block 8 and has the freedom of rotation. The driving block 8 is abutted against the driving wheel 7 by means of the driven wheel 9. The driving wheel 7 will produce relative movement in the vertical direction and generate friction in the process of pushing the driving block 8. Therefore, a driven wheel 9 is provided. Since the driven wheel 9 rotates synchronously with the driving wheel 7, the friction between the two is small, which can reduce the wear of the driving wheel 7 and the driving block 8 and increase the life of the tooling.
[0029] like Figure 1-4 As shown, a limit plate 10 and a slide 11 are also provided on the base 1, and the slide rail 4 is located on the surface of the slide 11. The gap between the limit plate 10 and the slide 11 forms a limit groove matching the fixed seat 2. The fixed seat 2 is detachably connected and fixed to the base 1 by means of the limit groove. The fixed seat 2 has the freedom to be connected up and down along the limit groove. The fixed seat 2 and the slide 5 can be provided with multiple groups, and can be coordinated by two groups of staff when in use. One group of staff is responsible for filling the mutual inductor 18 and the needle shell 19 into the fixed seat 2 and the slide 5, and the other group of staff uses the mutual inductor 18 and the needle shell 19 in the fixed seat 2 and the slide 5 to assemble. When one group of mutual inductors 18 and needle shells 19 are assembled, the empty fixed seat 2 and slide 5 are removed, and the next group of fixed seat 2 and slide 5 filled with mutual inductors 18 and needle shells 19 are immediately placed and assembled again. This cycle can improve work efficiency.
[0030] like Figure 1-4 As shown, baffles 12 are also provided on both sides of the fixed seat 2 and the sliding seat 5, and flanges are provided on both sides of the limiting plate 10. Gaps are left between the fixed seat 2 and the flanges on both sides to form a first slot 13, and gaps are left between the sliding seat 5 and the sliding rail 4 on both sides to form a second slot 14. The baffles 12 are respectively arranged on both sides of the fixed seat 2 and the limiting plate 10 with the help of the first slot 13 and the second slot 14. Since both sides of the first groove 6 and the second groove 3 are open, the needle shell 19 and the mutual inductor 18 in the first groove 6 and the second groove 3 may move horizontally and be misaligned, resulting in damage to the pins of the mutual inductor 18. Therefore, the baffle 12 is provided. After the fixed seat 2 and the sliding seat 5 filled with the mutual inductor 18 and the needle shell 19 are installed on the tooling, the baffle 12 is inserted to limit the edges of the needle shell 19 and the mutual inductor 18, thereby hindering the horizontal movement of the needle shell 19 and the mutual inductor 18 to avoid the above-mentioned problem.
[0031] like Figure 1-4As shown, a limiting protrusion 15 is provided on the side of the fixed seat 2 close to the sliding seat 5, and the sliding seat 5 abuts against the limiting protrusion 15 and forms a limit with the help of the limiting protrusion 15. In order to prevent the sliding seat 5 from being too close to the fixed seat 2 and causing the needle shell 19 to squeeze the mutual inductor 18 and cause damage, the utility model further provides a limiting protrusion 15 to limit the sliding seat 5. When the sliding seat 5 abuts against the limiting protrusion 15, the buckle 21 of the needle shell 19 is just embedded in the slot 22 of the mutual inductor 18.
[0032] like Figure 1-4 As shown, a push rod 16 is also provided on the driving wheel 7. With the help of the push rod 16, the driving wheel 7 has the freedom of forward and reverse rotation. When the staff performs assembly, it is more convenient to apply force by rotating the driving wheel 7 through the push rod 16.
