Description

Technical Field

[0001] The utility model relates to the technical field of toroidal transformer installation, in particular to a transformer adjustment device. Background Art

[0002] A toroidal transformer is a device that uses the principle of electromagnetic induction to change AC voltage. Its main components are the primary coil, secondary coil and iron core. Its main functions include voltage conversion, current conversion, impedance conversion, isolation and voltage stabilization. In modern technology, toroidal transformers have been widely used in computers, medical equipment, telecommunications, instruments and lighting.

[0003] After the toroidal transformer is manufactured, the operator will perform epoxy potting on the inner hole of the toroidal transformer according to the actual installation conditions and application scenarios. During potting, the positioning pins of the tooling base need to be potted. After potting, the customer's chassis will be pre-installed and inspected. The installation dimensions of the potted transformer cannot be adjusted. If the position of the toroidal transformer on the tooling base is inaccurate, it will affect the installation dimensions and performance of the toroidal transformer. If the pre-installation inspection fails, the relative position between the toroidal transformer and the tooling base needs to be readjusted and re-potted. The overall processing process of the transformer is complicated.

[0004] However, in the existing technology, the positions of the toroidal transformer and the tooling base are often fixed based on the experience of the operator. Even an operator with sufficient experience can hardly ensure that each toroidal transformer is accurately positioned on the tooling base. Utility Model Content

[0034] Obviously, the described embodiments are only part of the embodiments of the utility model, not all of them. Based on the embodiments of the utility model, other embodiments obtained by technicians in this field without creative work are all within the scope of protection of the utility model. The various technical features in the utility model can be combined interchangeably without conflicting with each other.

[0035] Reference Figures 1 to 5 The embodiment of the utility model provides a transformer calibration device, which can accurately position the toroidal transformer 400 before epoxy potting. After potting, the installation size of the toroidal transformer 400 is accurate, the performance is good and stable, and there is no need to pre-install the customer's chassis, which simplifies the processing procedure.

[0036] In this embodiment, the transformer adjustment device includes a mounting body, a movable baffle 200 and a fixed baffle 300 .

[0037] The installation body includes a base plate 100, a positioning pin 110 and a limiting assembly 130. The positioning pin 110 and the limiting assembly 130 are respectively connected to the upper surface of the base plate 100, the positioning pin 110 is extended in the up-down direction and is arranged in the middle of the base plate 100, and the limiting assembly 130 is arranged on the side of the base plate 100.

[0038] The movable baffle 200 includes a first baffle 210, a second baffle 220 and a third baffle 230. The first baffle 210 is extended along the left-right direction, while the second baffle 220 and the third baffle 230 are extended along the front-back direction respectively.

[0039] In this embodiment, the rear end of the second baffle 220 and the rear end of the third baffle 230 are respectively connected to the left end and the right end of the first baffle 210, and the first baffle 210, the second baffle 220 and the third baffle 230 together form an installation cavity 250, which is set to open forward.

[0040] In this embodiment, the connection between the movable baffle 200 and the upper surface of the bottom plate 100 is detachable. It can be understood that when the movable baffle 200 is installed on the bottom plate 100, the lower end surface of the first baffle 210, the lower end surface of the second baffle 220 and the lower end surface of the third baffle 230 are respectively in contact with the upper surface of the bottom plate 100, and the inner wall surface of the installation cavity 250 formed by the first baffle 210, the second baffle 220 and the third baffle 230 abuts against the limit assembly 130. The fixed stopper 300 is connected to the upper surface of the bottom plate 100 and is arranged at the front end of the installation cavity 250.

[0041] Before encapsulating the toroidal transformer 400, the toroidal transformer 400 is placed on the upper surface of the base plate 100, the positioning pin 110 is located in the inner hole 410 of the toroidal transformer 400, the front end of the toroidal transformer 400 is in contact with the fixed stopper 300, and after positioning, the movable stopper is installed on the base plate 100, and the position of the toroidal transformer 400 is accurately adjusted by the movable stopper, the first baffle 210, the second baffle 220 and the third baffle 230 surround the outer side of the toroidal transformer 400, that is, the toroidal transformer 400 is located in the installation cavity 250, the first baffle 210 is in contact with the rear end of the toroidal transformer 400, and the second baffle 220 and the third baffle 230 are respectively in contact with the left and right ends of the toroidal transformer 400, so that the relative position between the toroidal transformer 400 and the base plate 100 is fixed. The above steps can also be successfully completed by operators with little experience, ensuring that the relative position between the toroidal transformer 400 and the base plate 100 is accurate.

[0042] By accurately adjusting the movable baffle 200, the position of the toroidal transformer 400 on the installation body is determined and will not vary, thereby ensuring the installation size and performance of the toroidal transformer 400. There is no need to perform pre-installation inspection on the customer's chassis, simplifying the processing procedure.

[0043] In this embodiment, a plurality of mounting holes 120 are provided on the base plate 100, and the mounting holes 120 are located at the front and rear sides of the positioning pin 110. After the movable baffle 200 is installed, the mounting holes 120 are located at the front and rear ends of the mounting cavity 250. Since the installation position of the toroidal transformer 400 on the base plate 100 is accurate, after potting, the construction personnel do not need to perform pre-installation inspection on the customer chassis, and can directly install the potted toroidal transformer 400 through the mounting holes 120.

[0044] In this embodiment, two groups of mounting holes 120 are provided. The two groups of mounting holes 120 are respectively provided at the front end and the rear end of the mounting cavity 250 , and each group of mounting holes 120 is respectively provided with four mounting holes 120 .

[0045] It is understandable that the primary coil outlet point 420 of the toroidal transformer 400 is located at the front side of the toroidal transformer 400, and the secondary coil outlet point 430 is located at the rear side of the toroidal transformer 400. The primary coil outlet point 420 and the secondary coil outlet point 430 will not affect the use of the mounting hole 120 on the bottom plate 100.

[0046] It can be understood that the main function of the movable baffle 200 is to verify the position of the toroidal transformer 400 on the base. After the verification is completed, there is no need to remove the movable baffle 200 and then perform epoxy potting on the toroidal transformer 400. Since the toroidal transformer 400 is heavy, which can reach 30 kilograms, under normal circumstances, during the potting process, the positioned toroidal transformer 400 will not be offset relative to the base plate 100. Therefore, after the toroidal transformer 400 is positioned, there is no need to lock the movable baffle 200 on the base.

[0047] In some embodiments, the fixed stopper 300 includes a first stopper 310 and a second stopper 320. The first stopper 310 and the second stopper 320 are respectively connected to the upper surface of the bottom plate 100. The first stopper 310 is arranged in front of the positioning pin 110 to limit the front end of the toroidal transformer 400; and the second stopper 320 is arranged on the left or right side of the first stopper 310 to limit the left front side or the right front side of the toroidal transformer 400.

[0048] Specifically, the first stopper 310 is provided with a first stopper surface, which is arranged toward the rear, that is, toward the positioning pin 110. After the toroidal transformer 400 is installed, the front end of the toroidal transformer 400 is close to the first stopper surface. The second stopper 320 is provided with a second stopper surface, which is arranged at the rear side of the first stopper surface and toward the positioning pin 110.

[0049] It is understandable that, since the second stop block 320 is located at the left front or right front of the positioning pin 110, the second stop surface is tilted. After the annular transformer 400 is installed, the second stop surface is tangent to the annular transformer 400, and the annular transformer 400 can be tightly attached to the second stop surface.

[0050] With such arrangement, the first stop surface and the second stop surface can respectively locate two points on the front side of the annular transformer 400, thereby achieving accurate definition of the front end position of the annular transformer 400, which is facilitating subsequent adjustment of the left side, right side and rear side of the annular transformer 400 through the movable baffle 200.

[0051] It can be understood that the primary coil outlet point 420 is located on the left side or the right side of the first blocking surface and has a certain distance from the first blocking surface.

[0052] In this embodiment, the second stopper 320 is disposed on the left side of the first stopper 310 , the second stopper surface is located at the right end of the second stopper 320 , and the second stopper surface is inclined forward from left to right to face the positioning pin 110 .

[0053] The third baffle 230 is disposed on the right side of the first baffle 310 , the rear end of the third baffle 230 is connected to the right end of the first baffle 210 , and the front end of the third baffle 230 extends forward to a position flush with the front end of the first baffle 310 .

[0054] The second baffle 220 is arranged on the left side of the first baffle 310, the rear end of the second baffle 220 is connected to the left end of the first baffle 210 and extends forward, and the front end face of the second baffle 220 extends to a position where a first gap 330 is formed between the rear end face of the second baffle 320.

[0055] The second baffle 220 can adjust the left side of the toroidal transformer 400, and the third baffle 230 can adjust the right side of the toroidal transformer 400. When installing the movable baffle 200, the front end of the third baffle 230 is set to be flush with the front end of the first block 310. The position of the first block 310 can provide a reference for the position of the third baffle 230, so that the movable baffle 200 can be accurately installed on the bottom plate 100, thereby improving the accuracy of the adjustment.

[0056] It is understandable that, since there is a first gap 330 between the second baffle 220 and the second block 320, the problem of interference between the second block 320 and the second baffle 220 when the movable baffle 200 is installed can be avoided, and the first gap 330 can provide routing space for cables of other components.

[0057] After the toroidal transformer 400 is installed, the primary coil outlet point 420 of the toroidal transformer 400 is located on the left side of the first stopper 310 , and the distance between the primary coil outlet point 420 and the left end of the first stopper 310 is between 30 mm and 40 mm.

[0058] In some embodiments, the height of the second block 320 is lower than that of the first block 310 . This configuration is beneficial to the layout of the primary coil of the toroidal transformer 400 and avoids the second block 320 blocking the primary coil.

[0059] In some embodiments, the second stopper 320 is a PCB board, which can provide a carrier for the electrical connection of electronic components.

[0060] In some embodiments, the limiting assembly 130 includes a first limiting block 131 and a second limiting block 132 , and the first limiting block 131 and the second limiting block 132 are respectively connected to the upper surface of the bottom plate 100 .

[0061] After the movable baffle 200 is installed, the right end face of the first limit block 131 abuts against the left side face of the third baffle 230, and the rear end face of the second limit block 132 abuts against the front side face of the first baffle 210, that is, the first limit block 131 and the second limit block 132 are both arranged in the installation cavity 250 formed by the movable baffle 200.

[0062] It is understandable that the first limiting block 131 and the second limiting block 132 are provided to quickly position the left-right position and the front-back position of the movable baffle 200 , thereby quickly adjusting the position of the toroidal transformer 400 .

[0063] In this embodiment, two second limit blocks 132 are provided. The two second limit blocks 132 are arranged on the left and right. When the movable baffle 200 is installed, the rear end surfaces of the two second limit blocks 132 respectively abut against the front side surface of the first baffle 210, the right side surface of the second baffle 220 abuts against the left side surface of the second limit block 132 located on the left, and the left side surface of the third baffle 230 abuts against the right side surface of the second limit block 132 located on the right.

[0064] In this way, the second limit blocks 132 on the left and right sides respectively limit the left and right ends of the first baffle 210, which can ensure that the first baffle 210 extends in the left and right directions without tilting, thereby ensuring the accuracy of the installation of the movable baffle 200.

[0065] In some embodiments, the front end of the first limit block 131 is flush with the front end of the bottom plate 100, that is, flush with the front end of the third baffle 230 after the movable baffle 200 is installed. The front end of the bottom plate 100 faces the front end of the first limit block 131 for positioning, which is beneficial to the setting of the first limit block 131. The first limit block 131 and the second limit block 132 located on the right side respectively limit the front and rear ends of the third baffle 230, which is beneficial to keep the third baffle 230 extending in the front and rear direction without tilting. In addition, such a setting also makes the entire transformer adjustment device more beautiful.

[0066] In some embodiments, the movable baffle 200 further includes a fourth baffle 240 . The fourth baffle 240 is extended in the left-right direction, and the right end of the fourth baffle 240 is connected to the front end of the second baffle 220 .

[0067] The limiting assembly 130 further includes a third limiting block 133 , which is connected to the upper surface of the bottom plate 100 , and after the movable baffle 200 is installed, the rear end surface of the third limiting block 133 abuts against the front side surface of the fourth baffle 240 .

[0068] It is understandable that, by setting up in this way, the front side of the fourth baffle 240 is limited by the third limit block 133, which further ensures the accuracy of the relative position between the movable baffle 200 and the base plate 100, thereby accurately checking the position of the toroidal transformer 400 placed on the base plate 100.

[0069] In some embodiments, the connection between the stopper assembly 130 and the base plate 100 is detachable. Specifically in this embodiment, the first stopper 131, the second stopper 132, and the third stopper 133 are connected to the base plate 100 by screws, respectively. The operator can first calculate the positions of the front, rear, left, and right ends of the toroidal transformer 400 according to the positions of the positioning pins 110 and the mounting holes 120, and accurately install the first stopper 131, the second stopper 132, and the third stopper 133, so that the relative position of the movable baffle 200 and the base plate 100 can be accurate, the calibration accuracy of the toroidal transformer 400 can be improved, and the accuracy of the relative position between the toroidal transformer 400 and the base plate 100 can be ensured.

[0070] In some embodiments, the transformer adjustment device further includes a test reference block 140. In this embodiment, two test reference blocks 140 are provided, and the two test reference blocks 140 are respectively arranged on the left and right sides of the first stopper 310 and are respectively connected to the upper surface of the bottom plate 100.

[0071] The inspection reference block 140 is used to provide a reference point for the setting positions of the locating pins 110 and the mounting holes 120. When manufacturing the base plate 100, the inspection plate is aligned with the inspection reference block 140 and placed. The inspection plate is used to accurately measure the positions where the mounting holes 120 need to be opened and the positions where the locating pins 110 need to be installed, thereby ensuring the accuracy of the installation body and improving the position accuracy of the toroidal transformer 400.

[0072] It is understandable that the inspection reference block 140 is only needed when manufacturing the installation body. It can be detachably installed on the base plate 100 by means of screws and other connecting parts. After the installation body is manufactured, the inspection reference block 140 can be removed to avoid the inspection reference block 140 blocking the placement of the toroidal transformer 400.

[0073] In some embodiments, there is a second gap 340 between the first stopper 310 and the second stopper 320. Such a configuration is more conducive to accurate installation of the first stopper 310 and the second stopper 320. The first stopper 310 and the second stopper 320 are respectively arranged on the left and right sides of the inspection reference block 140 located on the left side, that is, the inspection reference block 140 located on the left side is located at the second gap 340, avoiding interference of the inspection reference block 140 with the installation of the first stopper 310 and the second stopper 320.

[0074] In addition, by setting the second gap 340, the first stop block 310 and the second stop block 320 are separated from each other, so as to limit the position of two points with a certain distance on the front side of the toroidal transformer 400, thereby improving the accuracy of the position limitation on the front side of the toroidal transformer 400 and reducing the overall weight of the fixed stop block 300.

[0075] In some embodiments, the movable baffle 200 is made of aluminum material. The movable baffle 200 made of aluminum material is light in weight, can reduce the weight of the entire transformer adjustment device, and is not easily damaged.

[0076] It is understandable that the connection between the first baffle 210 , the second baffle 220 , the third baffle 230 and the fourth baffle 240 of the movable baffle 200 may be achieved by gluing, welding, riveting, etc., which is not specifically limited here.
