Description

[0002] An inductor is a component that can convert electrical energy into magnetic energy and store it. The structure of an inductor is similar to that of a transformer, but it has only one winding. An inductor has a certain inductance, and it only impedes the change of current. If the inductor is in a state without current passing through, when the circuit is turned on, it will try to impede the current from flowing through it; if the inductor is in a state with current passing through, when the circuit is turned off, it will try to maintain the current unchanged.

[0003] An inductance can be made by winding a conductive material around a magnetic core, and it is a device that works based on the principle of electromagnetic induction. Inductance is an important part of an inductor. During the manufacturing process of an inductor, it needs to go through multiple processes for processing, especially involving transferring the inductors one by one to each process to complete the processing of each process before a finished inductor can be manufactured. Currently, during the production process, when transferring the inductors one by one to each process, the inductors are prone to change in position during the transfer process, which is not conducive to the processing of the inductors by the corresponding equipment in each production process.

For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific situations.

[0037] The following combines the attached Figures 1 to 3 And further illustrates the technical solutions of the present invention through specific implementation manners.

[0038] An inductor fixing tooling, comprising a tooling upper die 1, a tooling lower die 2 and a fixing component 3; the fixing component 3 is detachably installed on the tooling lower die 2, and the tooling upper die 1 is detachably installed on the top of the tooling lower die 2 through the fixing component 3;

[0039] The tooling upper die 1 includes an upper cover plate 11, two support rods 12 and a front-back limiting component. The two support rods 12 are relatively arranged at the left and right ends of the bottom of the upper cover plate 11. One end of the support rod 12 away from the upper cover plate 11 is detachably and limit-fitted with the fixing component 3, and the front-back limiting component is arranged at the bottom of the upper cover plate 11;

[0040] The tooling lower die 2 is provided with a limiting groove 21, and the bottom surface of the tooling lower die 2 is a horizontally arranged reference surface;

[0041] The upper cover plate 11, the support rods 12, the front-back limiting component and the limiting groove 21 enclose a limiting accommodation cavity for limiting and accommodating the inductor, and the front-back limiting component is used for restricting the front-back movement of the inductor.

[0042] As Figures 1-2 shown, the inductor fixing tooling (hereinafter referred to as "fixing tooling") of this embodiment is used in the inductor processing production line and is a tool for fixing and transferring the inductor. On the one hand, the fixing tooling of the present invention has a simple structure, convenient assembly and unlocking. On the other hand, it can ensure that the inductor does not shift or turn over during the transfer process, ensure the efficient operation of the entire inductor processing production line, and improve the automation degree of inductor production.

[0043] When using the inductor production line of this embodiment in cooperation, when it is necessary to fix the inductor, first place the bottom reference surface of the fixing tooling on the workbench, and then unlock the limit fit between the support rod 12 and the fixing component 3, move the tooling upper die 1 away from the top of the tooling lower die 2, and put the assembled inductor into the limiting groove 21 of the tooling lower die 2. Then reassemble the removed tooling upper die 1 and the tooling lower die 2, and the inductor is limited in the limiting accommodation cavity by the cooperation of the tooling upper die 1 and the tooling lower die 2 and cannot move up and down, and cannot move back and forth under the cooperation of the front-back limiting component. When the inductor is fixed in the inductor fixing tooling, it can be clamped and transferred by the clamping mechanism on the production line.

[0044] The inductor fixing tooling of the present invention effectively solves the problem of easy body position change of the inductor during the processing process through its unique design, improves production efficiency, processing accuracy and safety, reduces maintenance costs at the same time, enhances the adaptability and flexibility of the tooling, and has a significant improvement and promotion effect on the manufacturing process of the inductor.

[0045] Further, the front and rear limiting components include a front limiting sub-component 131 and a rear limiting plate 132, and the front limiting sub-component 131 and the rear limiting plate 132 are relatively parallelly arranged on the front and rear sides of the bottom of the upper cover plate 11.

[0046] Beneficial effects: The relatively parallelly arranged front limiting sub-component 131 and rear limiting plate 132 can more precisely control the movement of the inductor in the front and rear directions within the fixing fixture, and also enhance the structural stability of the fixing fixture. This design enables the inductor to be effectively restricted to a predetermined position even under the action of external forces during the processing, avoiding processing errors caused by position deviation. On the one hand, the stable limiting can ensure that the position of the inductor remains unchanged during the processing, thus avoiding processing quality problems caused by position deviation, helping to improve the yield rate and overall quality level of the inductor; on the other hand, it can ensure the precise processing of the inductor by the processing equipment, reduce the adjustment time during the processing, optimize the processing process, and improve the production efficiency.

[0047] Further explanation, the fixing fixture of this embodiment can be used to fix one or more inductors mentioned in Chinese Patent CN116457908A. Among them, the inductor is fixed in the limiting accommodation cavity by the cooperation of the upper die 1 of the fixture and the lower die 2 of the fixture, and the first component or the second component of the inductor core is respectively located within the positions opposite to the limiting groove 21 and the front and rear limiting components, while the relatively parallel front limiting sub-component 131 and rear limiting plate 132 correspondingly act on the relatively parallel vertical reference planes of the first component / second component of the inductor core, and by performing front and rear limiting on the core (the first component or the second component) located at the upper part of the assembled inductor, the entire inductor is thus subjected to front and rear limiting.

[0048] Furthermore, the front limiting sub-component 131 includes a front limiting plate 1311 and a plurality of telescopic plungers, the telescopic plungers are arranged inside the front limiting plate 1311, and the telescopic part of the telescopic plunger penetrates through the front limiting plate 1311 and protrudes from the rear part of the front limiting plate 1311;

[0049] The rear end face of the front limiting plate 1311 is parallel to the front end face of the rear limiting plate 132.

[0050] The telescopic property of the telescopic plunger enables the front limiting sub-component 131 to adapt to inductors of different sizes and shapes. By adjusting the protruding length of the plunger, the limiting range of the inductor can be flexibly controlled, enhancing the versatility and adaptability of the fixture.

[0051] When the upper die 1 of the fixture is assembled on the lower die 2 of the fixture on which the inductor has been placed, when the telescopic plunger contacts the inductor, the inductor squeezes the telescopic part protruding from the rear part of the front limiting plate 1311, the telescopic part of the telescopic plunger contracts forward, and at the same time, it cooperates with the rear limiting plate 132 to perform front and rear limiting on the inductor.

[0052] Furthermore, the telescopic plunger includes a tube body 1312, a first spring 1313, and a steel ball 1314;

[0053] The tube body 1312 is disposed inside the front limit plate 1311, and the tube body 1312 extends in the front-rear direction;

[0054] The first spring 1313 and the steel ball 1314 form the telescopic part. The first spring 1313 and the steel ball 1314 are disposed inside the tube body 1312, and the steel ball 1314 protrudes out of the rear end opening of the tube body 1312 in a movable manner in the front-rear direction.

[0055] The telescopic plunger includes a tube body 1312, a first spring 1313, and a steel ball 1314. Since the steel ball 1314 has the characteristic of automatic expansion and contraction under the cooperation of the first spring 1313, when the inductor is placed in the fixed tooling, the steel ball 1314 will automatically fine-tune according to the thickness dimension and shape of the inductor, improving the applicability of the fixed tooling.

[0056] Using the steel ball 1314 as the limiting element directly contacting the inductor, due to its spherical surface, it can provide more flexible and uniform contact pressure, reducing scratches or indentations on the surface of the inductor. At the same time, when the steel ball 1314 is under pressure, it can slightly retreat and compress the first spring 1313, thereby allowing the inductor to fine-tune its position within a certain range, improving the flexibility and adaptability of the limit. The spherical contact surface of the steel ball 1314 also ensures multi-point contact with the surface of the inductor, thus improving the accuracy and stability of the limit. At the same time, the elastic force of the first spring 1313 can maintain the continuous pressure of the steel ball 1314 on the inductor, preventing it from shifting during the processing.

[0057] Furthermore, a plurality of the telescopic plungers are provided on the front side of the lower die 2 of the fixture. The tube body 1312 penetrates through the front side of the lower die 2 of the fixture, and the steel ball 1314 protrudes out of the limit groove 21 in a movable manner in the front-rear direction.

[0058] By adding telescopic plungers on the front side of the lower die 2 of the fixture to form a double limit with the front limit component at the bottom of the upper cover plate 11, the position change of the inductor during the processing can be further restricted, reducing the processing error caused by position deviation, and fixing the inductor more firmly.

[0059] Due to the differences in size and shape among inductors of different specifications and shapes, a single limiting method may not meet all requirements. By setting front and rear limiting components on the upper die 1 of the fixture of the fixed tooling to limit the upper part of the inductor, and simultaneously adding telescopic plungers on the front side of the lower die 2 of the tooling to limit the lower part of the inductor, a more flexible limiting structure can be formed to adapt to more types of inductors, improving the versatility and adaptability of the tooling.

[0060] Further, first grooves 22 are provided at the left and right ends of the lower die 2 of the tooling, the fixing component 3 is arranged in the first grooves 22, and positioning holes penetrating through the first grooves 22 are provided at the top of the lower die 2 of the tooling;

[0061] The fixing component 3 includes a clamping block 31 and a second spring 32. The fixed end of the second spring 32 is connected to the inner wall of the first groove 22, and the movable end of the second spring 32 is connected to the clamping block 31; the clamping block 31 is a clamping block with a horizontal cross-section in the shape of a "concave" formed by a buckling block 311 and two convex columns 312. The convex columns 312 extend towards the notch of the first groove 22. A cover plate 4 is provided at the notch of the first groove 22. The cover plate 4 is used to limit the clamping block 31 in the first groove 22, and unlocking holes 41 are provided in the cover plate 4 corresponding to the positions of the convex columns 312;

[0062] A bayonet 121 is provided on the side of the end of the support rod 12 far from the upper cover plate 11, and the bayonet 121 is in snap-fit with the buckling block 311.

[0063] Further, first grooves 22 are provided on both sides of the lower die 2 of the fixture. The fixing component 3 is arranged in the first grooves 22. A positioning hole penetrating through the first grooves 22 is provided at the top of the lower die 2 of the fixture. The fixing component 3 includes a clamping block 31 and a second spring 32. The fixed end of the second spring 32 is connected to the inner wall of the first groove 22, and the movable end of the second spring 32 is connected to the clamping block 31. Further, the clamping block 31 is a clamping block with a horizontal cross-section in the shape of "concave" composed of a clamping buckle block 311 and two convex columns 312. When the upper die 1 of the fixture and the lower die 2 of the fixture are not assembled, the clamping buckle block 311 of the clamping block 31 does not completely block the positioning hole. When the lower end of the support rod 12 is inserted into the first groove 22 through the positioning hole; since a bayonet 121 (equivalent to the end inserted into the positioning hole) is provided at one end of the support rod 12 away from the upper cover plate 11, when the support rod 12 is inserted downward from the positioning hole, the support rod 12 will squeeze the clamping buckle block 311 of the clamping block 31. When the bayonet 121 of the support rod 12 moves downward to the position of the clamping buckle block 311, the support rod 12 no longer squeezes the clamping block 31 (the second spring 32), and the bayonet 121 and the clamping buckle block 311 are clamped and matched, and the upper die 1 of the fixture and the lower die 2 of the fixture are completely assembled. When it is necessary to take out the upper die 1 of the fixture from the lower die 2 of the fixture, the unlocking structure is inserted into the unlocking hole 41 of the cover plate 4, and the convex column 312 is correspondingly squeezed, so that the whole clamping block 31 moves towards the direction of the second spring, then the clamping buckle block 311 and the bayonet 121 of the support rod 12 can be separated, and the upper die 1 of the fixture can be taken out from the lower die 2 of the fixture.

[0064] A cover plate 4 is provided at the notch of the first groove 22, which can effectively limit the installation of the clamping block 31, and at the same time can effectively block dust or debris generated during the production process from entering the first groove 22 and affecting the fixing component 3.

[0065] Furthermore, two guiding blocks 23 and an anti-overturning side periphery 24 are further provided on the lower die 2 of the fixture. The two guiding blocks 23 are relatively arranged at the left and right ends of the top of the lower die 2 of the fixture. The two guiding blocks 23 are parallel to each other. The guiding block 23 is provided with a vertically penetrating guiding hole 231, and the guiding hole 231 is communicated with the positioning hole;

[0066] The anti-overturning side periphery 24 is arranged on the outer periphery of the limiting groove 21, and the anti-overturning side periphery 24 is located between the two guiding blocks 23. The anti-overturning side periphery 24 includes two limiting parts 241. The two limiting parts 241 are arranged on the front and rear sides of the anti-overturning side periphery 24, and the limiting parts 241 extend upward.

[0067] Further, a guiding block 23 is provided at the top of the lower die 2 of the fixture. The guiding block 23 is provided with a through guiding hole 231, and the guiding hole 231 communicates with the positioning hole. The support rod 12 of the upper die 1 of the fixture is inserted into the positioning hole through the guiding hole 231 protruding from the top surface of the lower die 2 of the fixture. The guiding hole 231 can guide the support rod 12, reduce the installation error caused by position deviation, and improve the positioning accuracy of the tooling.

[0068] The anti-overturning side periphery 24 provides additional support and restriction when the inductor is placed in the limiting groove 21, preventing it from overturning due to vibration or impact during the processing. The limiting parts 241 extending upward on the front and rear sides of the anti-overturning side periphery 24 can provide further limiting effect on the coil part in the middle of the inductor, ensuring the stable fixation of the inductor, contributing to improving the processing accuracy and consistency of the inductor, and reducing the potential risks during the processing.

[0069] The two guiding blocks 23 are located at the left and right ends and are parallel to each other. Cooperating with the limiting parts 241 on the front and rear sides of the anti-overturning side periphery 24, they can further position and limit the inductor.

[0070] Further, the upper die 1 of the fixture is also provided with a pressing component. The pressing component includes a pressing plate 141, a pressing block 142 and a third spring 143. The pressing block 142 is arranged below the pressing plate 141, and the pressing plate 141 and the pressing block 142 are connected by the third spring 143;

[0071] The upper cover plate 11 is formed with an activity groove 111 penetrating from top to bottom. The pressing plate 141 is installed on the top of the upper cover plate 11 and covers the activity groove 111. The bottom of the pressing block 142 protrudes from the bottom opening of the activity groove 111, and the pressing block 142 is movably arranged in the activity groove 111 up and down.

[0072] Further, the upper cover plate 11 is formed with an activity groove 111 penetrating from top to bottom. The pressing plate 141 is arranged on the top of the upper cover plate 11 and covers the activity groove 111. The bottom of the pressing block 142 protrudes from the bottom opening of the activity groove 111, and the pressing block 142 can move up and down relative to the activity groove 111. When the upper die 1 of the fixture covers the top of the lower die 2 to fix the inductor, the pressing block 142 touches the inductor in the limiting accommodation cavity, and the inductor will exert an upward force on the pressing block 142. Then the pressing block 142 moves upward in the activity groove 111 and squeezes the third spring upward to adapt to inductors of different heights, so as to prevent the upper cover plate 11 from crushing the inductor in the limiting accommodation cavity when the upper die 1 of the fixture covers the lower die 2 to realize the locking of the inductor fixing tooling. Further explanation, the addition of the third spring 143 not only plays a role in transmitting pressure, but also has a certain buffering effect. During the pressing process, the third spring 143 can absorb part of the impact force, reducing the direct impact and damage to the inductor.

[0073] The addition of the clamping assembly enables the inductor to adapt to inductors of different sizes in the fixed tooling, thereby improving the versatility and adaptability of the fixed tooling.

[0074] Furthermore, the left and right ends of the upper cover plate 11 are two symmetrical vertical reference surfaces, and the vertical reference surfaces are provided with first alignment holes 112;

[0075] The front limiting plate 1311 and the rear limiting plate 132 are provided with a second alignment hole 113 .

[0076] The two vertical reference surfaces of the upper cover plate 11 are provided with first alignment holes 112 which can cooperate with the protrusions of the clamping mechanism in the production line, so that the fixed tooling is not easily separated from the clamping mechanism due to gravity during the process of transferring the fixed tooling by the clamping mechanism.

[0077] Furthermore, the front limiting plate 1311 and the rear limiting plate 132 are provided with a second alignment hole 113, which also provides another clamping position for the clamping mechanism, thereby improving the versatility and applicability of the fixing tool.

[0078] Furthermore, a guide groove 5 is provided at the bottom of the jig lower mold 2, and the guide groove 5 is extended in the left-right direction.

[0079] The bottom of the jig lower die 2 is provided with a guide groove 5 extending left and right. The guide groove 5 is provided at the bottom of the inductor fixing tool of this embodiment in order to make the inductor fixing tool suitable for the inductor production and processing assembly line. The guide groove 5 is provided at the bottom of the inductor fixing tool so that the inductor fixing tool can slide on the guide rail on the processing production line. Preferably, there are two guide grooves 5, and the two guide grooves 5 are parallel to each other, which is conducive to the smooth and stable sliding of the inductor fixing tool on the guide rail.
