[0002] Inductors are components that convert electrical energy into magnetic energy and store it. Based on the magnetic conductor, they can be classified into air-core coils, ferrite coils, and iron-core coils.

[0018] To make the technical problems, technical solutions, and beneficial effects to be solved by this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and are not intended to limit the scope of this application.

[0019] It should be noted that when a component is referred to as being "mounted to," "fixed to," or "set on" another component, it can be directly on or indirectly on that other component. When a component is referred to as being "connected to" another component, it can be directly connected to or indirectly connected to that other component.

[0020] It should be understood that the terms "length", "width", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this application.

[0021] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this application, "multiple" means two or more, unless otherwise explicitly specified.

[0022] like Figures 1 to 8 As shown, this application provides a testing fixture for inductor production, including a base 1, a testing mechanism 2, two clamping mechanisms 3, and a vibration mechanism 4. The testing mechanism 2 includes a driver 21, a support platform 22, and a force gauge 23. The driver 21 is mounted on the base 1, the support platform 22 is mounted on the driver 21 and moves along a first direction under the drive of the driver 21, and the force gauge 23 is mounted on the support platform 22. One clamping mechanism 3 is mounted on the base 1, and the other clamping mechanism 3 is mounted on the force gauge 23. The clamping mechanism 3 includes a mounting frame 31, a housing 32, an active component 33, and multiple clamping components 34. The housing 32 is mounted on the mounting frame 31, the active component 33 is mounted on the housing 32, and the multiple clamping components 34 are all mounted on the housing 32 and converge towards each other or expand backwards under the drive of the active component 33. The vibration mechanism 4 is mounted on the base 1.

[0023] It should be noted that the "first direction" above and below refers to the bidirectional direction of the shortest connecting line between the two clamping mechanisms 3, specifically as follows: Figure 1 The X-axis is shown in the figure.

[0024] This application provides a testing fixture for inductor production. Under the action of two clamping mechanisms 3, an air-core coil can be clamped. Driven by a driver 21, one clamping mechanism 3 moves in a first direction away from the other clamping mechanism 3 via a support platform 22 and a force gauge 23, thereby applying tension to the air-core coil. The force gauge 23 detects the magnitude of the tension acting on the air-core coil. In summary, by applying different magnitudes of tension to the air-core coil, the stress conditions of the air-core coil in actual applications can be simulated, and after the force is applied, the presence of gaps, cracks, etc., in the air-core coil can be detected, thus enabling the testing of the air-core coil's mechanical properties. Under the action of a vibration mechanism 4, the air-core coil can vibrate, similarly simulating the working conditions of the air-core coil, thereby enabling the testing of the air-core coil's mechanical properties under vibration, resulting in more accurate test results. In addition, before clamping the air coil, the distance between the two clamping mechanisms 3 can be adjusted by the driver 21, which can be used to clamp air coils of different lengths. The distance between the multiple clamping components 34 can be adjusted by the active component 33, which can be used to clamp air coils of different diameters, thus helping to improve the applicability of the inspection fixture.

[0025] In one embodiment of this application, please refer to Figures 1 to 8 The outer casing 32 includes a casing 321, a cover 322, multiple sliding grooves 323, and multiple first straight-sided waist-shaped holes 324. The casing 321 has an opening, and the cover 322 is installed at the opening of the casing 321. The multiple sliding grooves 323 are all formed inside the casing 321 and are evenly arranged circumferentially around a first direction. The multiple first straight-sided waist-shaped holes 324 are all formed on the inner circumference of the casing 321 and communicate with the multiple sliding grooves 323, and are arranged one-to-one with the multiple sliding grooves 323. The active component 33 includes a rotating disk 331 and multiple arc-shaped waist-shaped holes 332. The rotating disk 331 is rotatably disposed inside the casing 321, and the multiple arc-shaped waist-shaped holes 332 are all formed in the rotating disk 331 and are arranged one-to-one with the multiple first straight-sided waist-shaped holes 324. The clamping assembly 34 includes a slide rod 341 and a first limiting rod 342. The slide rod 341 passes through the slide groove 323, and the first limiting rod 342 is connected to the slide rod 341 and passes through the first straight side waist-shaped hole 324 and the arc side waist-shaped hole 332.

[0026] This configuration, under the action of the first straight-edged oblong hole 324, guides the first limiting rod 342, ensuring that the slide rod 341 can only move radially along the rotating disk 331, thus improving the stability of the slide rod 341's movement. Under the rotation of the rotating disk 331, the first limiting rod 342 can move radially along the rotating disk 331 through the oblong hole 332; through multiple oblong holes 332, multiple first limiting rods 342 can converge towards each other or expand away from each other radially along the rotating disk 331, thereby causing multiple slide rods 341 to converge towards each other or expand away from each other, thus enabling the fixation of air-core coils of different diameters with good fixing effect.

[0027] In one embodiment of this application, please refer to the following: Figures 1 to 8 The outer casing 32 also includes a plurality of second straight-edged oblong holes 325, which are all formed on the outer periphery of the casing 321 and communicate with a plurality of sliding grooves 323, and are arranged one-to-one with the sliding grooves 323. The clamping assembly 34 also includes a second limiting rod 343, which is connected to the sliding rod 341 and passes through the second straight-edged oblong holes 325.

[0028] With this configuration, the second straight-edge waist-shaped hole 325 and the second limiting rod 343 can also guide the first limiting rod 342, which helps to further improve the movement stability of the slide rod 341 on the rotating disk 331.

[0029] In one embodiment of this application, see [reference] Figures 1 to 8The active component 33 includes a rotating disk 331, a worm gear 333, a knob 334, and a worm wheel 335. The rotating disk 331 is rotatably disposed inside the housing 32, the worm gear 333 is rotatably disposed through the housing 32, the knob 334 is mounted on one end of the worm gear 333, and the worm wheel 335 is mounted on the rotating disk 331 and meshes with the worm gear 333. It is also configured to drive the rotating disk 331 to rotate around the first direction when the worm gear 333 rotates around the second direction.

[0030] It should be noted that the "above" and "below" second directions refer to the bidirectional direction of the shortest line connecting the first limiting plate 433 and the second limiting plate 434, as detailed below. Figure 1 The Y-axis is shown in the figure.

[0031] With this configuration, the rotation of knob 334 drives worm gear 333 to rotate worm wheel 335 in the first direction, which in turn drives rotating disk 331 to rotate in the first direction, making adjustment convenient. Furthermore, under the action of worm wheel 335 and worm gear 333, and with multiple support plates 344 clamping the air-core coil, self-locking is achieved, preventing the air-core coil from detaching from clamping mechanism 3 during testing and ensuring normal testing.

[0032] In one embodiment of this application, please refer to Figures 1 to 8 The clamping assembly 34 includes a slide rod 341 and a support plate 344. The slide rod 341 passes through the housing 32, and the support plate 344 is connected to the slide rod 341.

[0033] With this configuration, under the action of the slide bar 341, the support plate 344 can also move radially along the rotating disk 331, which can press the support plate 344 against the inner circumference of the air coil. Under the combined action of multiple support plates 344, air coils of different diameters can be tightened, resulting in a good fixing effect.

[0034] In one embodiment of this application, please refer to the following: Figures 1 to 8 The clamping assembly 34 also includes a clamping plate 345 and a locking member. The clamping plate 345 is sleeved on the slide rod 341, and the locking member is installed on the support plate 344. The locking member includes a locking screw 346 and a locking nut 347. The locking screw 346 is installed on the side of the support plate 344 facing the clamping plate 345, and the locking nut 347 is screwed to the locking screw 346 and is located on the side of the clamping plate 345 facing away from the support plate 344.

[0035] This configuration, under the action of the locking mechanism, allows the clamping plate 345 to be locked to the outer periphery of the air-core coil, thereby fixing the air-core coil from its outer periphery. With the action of multiple support plates 344, the air-core coil can be fixed simultaneously from both its inner and outer periphery, resulting in better clamping performance. Furthermore, the clamping plate 345 can move relative to the support plate 344, and can also be used to clamp air-core coils of different thicknesses, further expanding the applicability of the testing fixture.

[0036] In one embodiment of this application, see [reference] Figures 1 to 8 The vibration mechanism 4 includes a first adjustment component 41, a second adjustment component 42, an elastic support 43, and a vibrator 44. The first adjustment component 41 is mounted on the base 1, the second adjustment component 42 is mounted on the first adjustment component 41 and moves along a first direction under the drive of the first adjustment component 41, the elastic support 43 is mounted on the second adjustment component 42 and moves along a second direction under the drive of the second adjustment component 42, and the vibrator 44 is mounted on the elastic support 43.

[0037] This configuration allows the air-core coil to vibrate during testing under the action of the vibrator 44, thus enabling the detection of the air-core coil's mechanical properties under vibration. The first adjustment component 41 and the second adjustment component 42 can adjust the position of the vibrator 44 in the first and second directions, allowing the air-core coil to vibrate from different positions, resulting in more comprehensive and accurate test results. It also allows for the vibration of air-core coils of different sizes, thus expanding its applicability. The elastic support 43 prevents the impact force of the vibrator 44 from directly acting on the first and second elastic components, effectively protecting them.

[0038] In one embodiment of this application, please refer to Figures 1 to 8 The elastic bracket 43 includes a first mounting plate 431, multiple elastic connectors, and a second mounting plate 432. The first mounting plate 431 is mounted on the second adjustment assembly 42, and the multiple elastic connectors are all mounted on the first mounting plate 431. The second mounting plate 432 is mounted on the multiple elastic connectors. Each elastic connector includes a first limiting plate 433, a second limiting plate 434, a mounting rod 435, an intermediate plate 436, and two elastic structures 437. The first limiting plate 433 and the second limiting plate 434 are both mounted on the first mounting plate 431 and are spaced apart along a second direction. The mounting rod 435 passes through the first limiting plate 433 and the second limiting plate 434. The intermediate plate 436 is formed on the outer periphery of the mounting rod 435. Elastic structures 437 are provided between the first limiting plate 433 and the intermediate plate 436, and between the second limiting plate 434 and the intermediate plate 436. Both elastic structures 437 are sleeved on the mounting rod 435.

[0039] With this configuration, when the vibrator 44 applies impact force to the mounting rod 435 through the second mounting plate 432, the two elastic structures 437 can prevent the intermediate plate 436 from directly contacting the first limiting plate 433 and the second limiting plate 434, thereby offsetting the impact force of the vibrator 44, effectively protecting the first adjusting component 41 and the second adjusting component 42, and extending the service life of the first adjusting component 41 and the second adjusting component 42.

[0040] Optionally, the elastic structure 437 is configured as a spring or a sheet.

[0041] In one embodiment of this application, please refer to the following: Figures 1 to 8 The first adjustment component 41 includes a first adjustment bracket 411, a first adjustment screw 412, a first guide rod 413, a first handle 414, and a first slider 415. The first adjustment bracket 411 is mounted on the base 1, the first adjustment screw 412 is mounted on the first adjustment bracket 411, the first guide rod 413 is mounted on the first adjustment bracket 411, the first handle 414 is mounted on one end of the first adjustment screw 412 and can drive the first adjustment screw 412 to rotate around a first direction, and the first slider 415 is sleeved on the first adjustment screw 412 and the first guide rod 413 and screwed to the first adjustment screw 412.

[0042] This configuration allows the first slider 415 to move along the first direction under the rotation of the first adjusting screw 412, thereby adjusting the position of the vibrator 44 in the first direction. The first guide rod 413 guides the first slider 415, ensuring it moves along the first direction and preventing it from rotating with the first adjusting screw 412, thus improving the stability of its movement in the first direction. The first handle 414 facilitates the rotation of the first adjusting screw 412, enhancing ease of use.

[0043] In one embodiment of this application, see [reference] Figures 1 to 8 The second adjustment assembly 42 includes a second adjustment bracket 421, a second adjustment screw 422, a second guide rod 423, a second handle 424, and a second slider 425. The second adjustment bracket 421 is mounted on the first adjustment assembly 41, the second adjustment screw 422 is mounted on the second adjustment bracket 421, the second guide rod 423 is mounted on the second adjustment bracket 421, the second handle 424 is mounted on one end of the second adjustment screw 422 and can drive the second adjustment screw 422 to rotate around a second direction, and the second slider 425 is sleeved on the second adjustment screw 422 and the second guide rod 423 and screwed to the second adjustment screw 422.

[0044] With this configuration, the rotation of the second adjusting screw 422 drives the second slider 425 to move along the second direction, thereby adjusting the position of the vibrator 44 in the second direction. The second guide rod 423 guides the second slider 425, allowing it to move along the second direction and preventing it from rotating with the second adjusting screw 422, thus improving the stability of its movement in the second direction. The second handle 424 facilitates the rotation of the second adjusting screw 422, enhancing ease of use.

[0045] The working principle of the inductor manufacturing testing fixture provided in this application is as follows: First, the air-core coil is placed between two clamping mechanisms 3. The operator rotates knob 334, which, through worm gear 335 and worm 333, drives rotating disk 331 to rotate in the first direction. Under the action of rotating disk 331, multiple first limiting rods 342 and multiple second limiting rods 343 unfold in opposite directions until multiple support plates 344 press against the inner circumference of the air-core coil. Then, the operator tightens locking nut 347, so that multiple clamping plates 345 fit tightly against the outer circumference of the air-core coil. After clamping, the operator starts driver 21. Driver 21 drives carrier platform 22 to move in the first direction away from machine base 1. Under the action of tension gauge 23, the magnitude of the tension force exerted by driver 21 on the air-core coil can be detected. The operator gradually increases the tension force exerted by driver 21 on the air-core coil and carefully observes the appearance of the air-core coil until gaps or breaks appear in the air-core coil. At this point, the ultimate tension value of the air-core coil can be detected. Similarly, during the testing process, the operator uses the first adjustment component 41 and the second adjustment component 42 to bring the vibrator 44 into contact with the outer periphery of the air-core coil. Under the action of the vibrator 44, the air-core coil vibrates, which can simulate the mechanical properties of the air-core coil under vibration.

[0046] One or more embodiments in this application are intended to cover all such substitutions, modifications, and variations that fall within the broad scope of this application. Therefore, any omissions, modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of one or more embodiments in this application should be included within the protection scope of this application.
