Description

Technical Field

[0001] This utility model relates to the field of transformer manufacturing technology, specifically to a transformer potting auxiliary positioning device. Background Technology

[0002] A toroidal transformer is a common type of transformer, generally consisting of a toroidal core, a primary winding, and a secondary winding, with the primary and secondary windings wound sequentially around the toroidal core. The toroidal core has a central hole. This central hole is typically filled with adhesive. To facilitate installation of the toroidal transformer with other equipment, connection holes are machined into the filled central hole.

[0003] The machining of the connecting hole usually involves setting up a core post on the machining table, placing the toroidal transformer on the core post, and ensuring that the axis of the core post coincides with the axis of the central hole. Then, glue is applied, and the toroidal transformer is separated from the core post after the glue has cured. Currently, when placing toroidal transformers, the alignment of the core column and the center hole is often achieved manually or with the aid of a device. This requires workers to repeatedly move the transformer, resulting in significant deviations and potentially causing misalignment of the connection holes after the adhesive has cured. Existing auxiliary devices typically rely on positioning sleeves mounted on the core column. The toroidal transformer is fitted onto the positioning sleeve for positioning, and the sleeve is removed from the core column before adhesive application. However, different sized positioning sleeves are required for aligning toroidal transformers with different center hole sizes, making the device less versatile.

[0004] In view of the problems existing in the prior art, this utility model designs and manufactures a transformer potting auxiliary positioning device to overcome the above defects. Summary of the Invention

[0005] To address the problems existing in the prior art, this utility model provides a transformer potting auxiliary positioning device, which can increase the applicability of the device.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows: a transformer potting auxiliary positioning device, comprising a stud installed on the upper end of the core column, wherein an installation ring is connected to the stud; The mounting ring includes a nut and a mounting sleeve. The nut is threadedly connected to the stud, and the lower end of the nut is rotatably connected to the mounting sleeve. The inner diameter of the mounting sleeve is larger than the outer diameter of the stud. The mounting cylinder has several guide plates equidistantly arranged on its lower end face. The upper end of the guide plates is rotatably connected to the mounting cylinder, and a roller is rotatably mounted on the lower end of the guide plates. The roller can move radially along the mounting cylinder.

[0007] Preferably, the guide plate is an arc-shaped plate, and the diameter of the guide plate gradually decreases upward along the axial direction.

[0008] Preferably, the guide plate axis is always located between the core column axis and the guide plate.

[0009] Preferably, the lower end face of the guide plate is provided with a rounded chamfer.

[0010] Preferably, the lower end face of the guide plate is provided with a first mounting groove, the roller is rotatably mounted on the first mounting groove, and the roller extends from the lower end of the first mounting groove.

[0011] Preferably, the lower end of the mounting cylinder is provided with a plurality of second mounting slots corresponding one-to-one with the guide plate, and a connecting seat is mounted on the upper surface of the guide plate, the connecting seat being rotatably mounted on the second mounting slot.

[0012] Preferably, the connection between the connecting seat and the guide plate is integrally formed.

[0013] Preferably, the connecting seat and the first mounting groove are located on the middle section of the upper and lower end faces of the guide plate, respectively.

[0014] The beneficial effects of this utility model are as follows: 1. This utility model has several guide plates rotatably installed at the lower end of the mounting ring. The opening and closing of the guide plates is controlled by adjusting the height of the mounting ring, and the inclination of the guide plates is adjusted to adapt to the centering needs of different sized holes, thereby increasing the versatility of the device.

[0015] 2. The rounded chamfer and rollers on the lower end face of the guide plate of this utility model can prevent the rubber pad from being scratched. The rollers can also guide the sliding of the guide plate and prevent the guide plate from shaking during the adjustment process.

[0016] 3. This utility model uses several guide plates to form a conical surface with a gradually increasing diameter from top to bottom. After the inclined conical surface comes into contact with the toroidal transformer, it can move from all directions toward the positioning direction, thereby realizing the rapid placement and positioning of the toroidal transformer.

[0019] To facilitate understanding by those skilled in the art, the present invention will be further described below with reference to the accompanying drawings.

[0020] like Figure 1-3 The transformer potting auxiliary positioning device shown includes a stud 10 mounted on the upper end of a core column 5. A mounting ring is connected to the stud 10, and the mounting ring includes a nut 9 and a mounting sleeve 8. The nut 9 is threadedly connected to the stud 10, integrating the nut 9 and the mounting sleeve 8 into a single unit to ensure strong connection. The lower end of the nut 9 is rotatably connected to the mounting sleeve 8, and the inner diameter of the mounting sleeve 8 is larger than the outer diameter of the stud 10. This utility model features a stud 10 that, in conjunction with a nut 9, allows for adjustment of the vertical height of the mounting ring. It also facilitates the separation of the mounting ring from the core post 5, enabling easy disassembly and installation. The operation is convenient.

[0021] Specifically, a number of guide plates 7 are equidistantly arranged on the lower end face of the mounting cylinder 8, and a number of second mounting grooves 11 corresponding one-to-one with the guide plates 7 are provided at the lower end of the mounting cylinder 8. A connecting seat 12 is installed on the upper end face of the guide plate 7, and the connecting seat 12 and the guide plate 7 are integrally formed. The connecting seat 12 is rotatably mounted on the second mounting groove 11.

[0022] In this invention, several guide plates 7 together form a conical surface with a gradually increasing diameter from top to bottom. After the inclined conical surface contacts the toroidal transformer 1, it can move from various directions toward the positioning direction, enabling rapid placement and positioning of the toroidal transformer 1. When the nut 9 is rotated, the entire mounting ring can move up and down. At this time, the lower end of the guide plate 7 will gradually move closer to or away from the core column 5 along the axial direction, thereby adjusting the inclination of the conical surface to adapt to the centering needs of different sized holes and increase the versatility of the device.

[0023] Specifically, the guide plate 7 is an arc-shaped plate, and the axis of the guide plate 7 is always located between the axis of the core column 5 and the guide plate 7. The outward protrusion of the guide plate 7 can increase the contact area with the hole in the toroidal transformer 1, distribute the force to avoid the force concentration on the guide plate 7 and extend its service life. The arc-shaped surface can also prevent scratches on the inner wall of the toroidal transformer 1.

[0024] The diameter of the guide plate 7 of this utility model gradually decreases upward along the axial direction. When several guide plates 7 come together and contact each other, the conical surface formed also gradually decreases in diameter upward along the axis of the core column 5. When placing a ring transformer 1 with any hole size within the applicable range, it can gradually guide it to move closer to the positioning direction.

[0025] Specifically, the upper end of the guide plate 7 is rotatably connected to the mounting cylinder 8, and a roller 6 is rotatably mounted on the lower end of the guide plate 7. A first mounting groove 4 is provided on the lower end face of the guide plate 7, and the roller 6 is rotatably mounted on the first mounting groove 4, extending from the lower end of the first mounting groove 4. The roller 6 can move radially along the mounting cylinder 8. The lower end face of the guide plate 7 is provided with a rounded chamfer 14.

[0026] Specifically, before placing the toroidal transformer 1, a rubber pad 3 needs to be placed on the workbench 2. The rubber pad 3 can be placed under the toroidal transformer 1 to prevent leakage during glue pouring. The rounded chamfer 14 and roller 6 on the lower end face of the guide plate 7 can prevent the rubber pad 3 from being scratched. The roller 6 can also guide the sliding of the guide plate 7 and prevent the guide plate 7 from shaking during the adjustment process.

[0027] After the toroidal transformer 1 is placed, the nut 9 is rotated to control the installation cylinder 8 and the guide plate 7 to move upward. As the nut 9 rises, the lower end gradually moves closer to the core column 5. The diameter of the lower end of the cone formed by the guide plate 7 after it gathers together is smaller than the diameter of the central hole, so it can be directly taken out from the central hole without interference.

[0028] Specifically, since the nut 9 and the mounting cylinder 8 can rotate relative to each other, the guide plate 7 will not rotate with the nut 9 when the nut 9 is rotated. Therefore, the path of the roller 6 in contact with the rubber pad 3 will not change with the rotation of the nut 9. It will only reciprocate along the axis of the core column 5, avoiding increased friction that affects the opening and closing of the guide plate 7 and preventing damage to the rubber pad 3 during the process of removing the guide plate 7.

[0029] The connecting seat 12 and the first mounting groove 4 of this utility model are located on the middle section of the upper and lower end faces of the guide plate 7, respectively, which can keep the guide plate 7 stable during retraction and avoid tilting to one side.

[0030] It should be understood that these embodiments are for illustrative purposes only and are not intended to limit the scope of protection of this utility model. Furthermore, it should be understood that after reading the technical description of this utility model, those skilled in the art can make various alterations, modifications, and / or variations to this utility model, and all such equivalent forms also fall within the scope of protection defined by the appended claims.
