[0027] In order to make the purpose, technical scheme and advantages of the embodiments of the present application more clear, the following will combine the drawings in the embodiments of the present application to clearly and completely describe the technical scheme in the embodiments of the present application. Obviously, the described embodiments are some embodiments of the present application, not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor are within the protection scope of the present application.
[0028] The following will describe the embodiments of the present application in combination with Figs. 1 to 4
[0029] A coil pressing jig, comprising:
[0030] The base 1 is provided with the first positioning groove 11 suitable for placing the inductance coil 3;
[0031] The fixing member 2 is provided with a second positioning groove 21, when the inductor coil 3 is placed in the first positioning groove 11, the fixing member 2 is arranged on the inductor coil 3, and the second positioning groove 21 is arranged correspondingly with the first positioning groove 11, so as to be clamped on the opposite two end faces of the inductor coil 3 respectively.
[0032] The coil pressing jig provided by the embodiment comprises a base 1, the base 1 is provided with a first positioning groove 11 suitable for placing an inductor coil 3; a fixing member 2, the fixing member 2 is provided with a second positioning groove 21, when the inductor coil 3 is placed in the first positioning groove 11, the fixing member 2 is arranged on the inductor coil 3, and the second positioning groove 21 is arranged correspondingly with the first positioning groove 11, so as to be clamped on the opposite two end faces of the inductor coil 3 respectively.
[0033] Through the cooperation of the first positioning groove 11 on the base 1 and the second positioning groove 21 on the fixing member 2, when the inductor coil 3 is placed in the first positioning groove 11, the fixing member 2 is arranged on the inductor coil 3, and the two positioning grooves correspondingly clamp the opposite two end faces of the inductor coil 3, then a rubber hammer is used to knock the fixing member 2, and the inductor coil 3 is pressed tightly by the external force generated by the knocking, so that the natural height of the inductor coil 3 is lowered, and the required process height is reached. The problem of loose and bouncing of the inductor coil 3 after being wound and formed due to its own structural characteristics is effectively solved, the situation that the natural height of the inductor coil exceeds the established process standard is avoided, and the subsequent processing process can be smoothly pushed forward. The tool replaces the operation of employees grasping and repeatedly knocking the inductor coil by hand, and reduces the high-intensity physical labor of employees. During the whole operation process, the contact between the hands of employees and the inductor coil and the equipment is greatly reduced, and only the rubber hammer needs to be held to knock the fixing member 2, which further ensures the safety of the operation. The safety hidden danger of injury caused by frequent contact of hands with the equipment is reduced, the convenience and efficiency of the inductor coil pressing process are improved, and the processing process of the inductor coil 3 is optimized as a whole. The number of the first positioning groove 11 and the second positioning groove 21 can be one or more according to needs, which is not limited specifically herein, and two is preferred.
[0034] Further, the groove bottom of the second positioning groove 21 is inwardly recessed to form a guide groove 22, and the groove bottom of the first positioning groove 11 is provided with a guide column 12, when the inductor coil 3 is placed in the first positioning groove 11, the inductor coil 3 is arranged on the guide column 12, and the guide column 12 is at least partially inserted into the guide groove 22.
[0035] It is easy to understand that the guide groove 22 is formed in the center of the second positioning groove 21, the shape of the guide column 12 is consistent with the shape of the inner cavity of the inductor coil 3, and the guide groove 22 and the guide column 12 provide positioning function for the placement and fixation of the inductor coil 3. When the inductor coil 3 is placed in the first positioning groove 11, it is sleeved on the guide column 12, and the guide column 12 is at least partially inserted into the guide groove 22, which ensures that the position of the coil is consistent in height each time, avoiding uneven compression effect due to placement deviation. When the rubber hammer is used to knock the fixing part 2 later, the coil will not be displaced, skewed, etc., effectively ensuring the accuracy and stability of the compression process, further improving product quality, while reducing repeated operations that may be caused by position deviation, improving overall processing efficiency.
[0036] In an optional embodiment, the concave-convex structure of the guide column 12 and the guide groove 22 can be interchanged, that is, the groove bottom of the first positioning groove 11 is provided with the inwardly recessed guide groove 22, and the groove bottom of the second positioning groove 21 is partially outwardly protruded to form the guide column 12, and when the fixing part 2 is sleeved on the coil, the guide column 12 is inserted into the guide groove 22. It also has the effect of positioning. During mold manufacturing or jig assembly, the scheme that is easier to process and form can be selected according to the actual process difficulty and material characteristics, so as to reduce production cost, improve production flexibility, and meet the needs of the coil compression jig in different production scenes.
[0037] It should be noted that in the present embodiment, the end face of the inductor coil 3 to be compressed is of an "8" shape, which has two hollow regions, that is, two guide columns 12 and two guide grooves 22 are correspondingly provided. When placing the coil, the operator needs to accurately insert the hollow region into the guide column 12, so that the inductor coil 3 is quickly and stably placed in the first positioning groove 11, reducing the placement difficulty. When knocking and compressing later, the two guide columns 12 cooperatively limit the displacement of the coil, ensuring that it is stressed along the predetermined trajectory, avoiding deformation and distortion. Of course, in other embodiments, a corresponding number of guide columns 12 and guide grooves 22 can be provided according to the specific form of the inductor coil 3 to ensure stable fixation of the inductor coil 3.
[0038] Further, the base 1 is also provided with a positioning column 13, and the fixing part 2 is provided with a positioning hole 23, and the positioning column 13 is adapted to be inserted into the positioning hole 23.
[0039] It is easy to understand that the positioning column 13 is a cylindrical column, and the positioning hole 23 is a circular hole, which can also be a square column or a square hole, which is not specifically limited here. The positioning column 13 on the base 1 cooperates with the positioning hole 23 on the fixing part 2, which enhances the stability of the base 1 and the fixing part 2 when they are combined. When the inductor coil 3 is placed and the fixing part 2 is ready to be covered and pressed, the positioning column 13 is accurately inserted into the positioning hole 23, so that the fixing part 2 can be quickly and accurately positioned and will not shift or shake. Not only does it ensure that the fixing part 2 and the base 1 are always tightly fitted during the use of the rubber hammer, so that the coil receives uniform and stable pressure, ensuring the quality of the pressing, but also reduces the adjustment time of the operator when installing the fixing part 2, further improving the overall work efficiency, and providing strong support for efficient and accurate coil pressing operation.
[0040] Further, the number of positioning columns 13 is at least two, and the at least two positioning columns 13 are respectively arranged on both sides of the first positioning groove 11; the number of positioning holes 23 is at least two, and is arranged correspondingly with the positioning columns 13.
[0041] It is easy to understand that the positioning column 13 on the base 1 cooperates with the positioning hole 23 on the fixing part 2, which enhances the stability of the base 1 and the fixing part 2 when they are combined. The positioning column 13 is inserted into the positioning hole 23, so that the fixing part 2 is accurately positioned and will not shift or shake. Not only does it ensure that the fixing part 2 and the base 1 are always tightly fitted during the use of the rubber hammer, so that the coil receives uniform and stable pressure, ensuring the quality of the pressing, but also reduces the adjustment time of the operator when installing the fixing part 2, further improving the overall work efficiency.
[0042] In an optional embodiment, a magnetic attraction type positioning structure can be used to replace the existing column hole plug-in mode. That is, a magnet is embedded in the corresponding position of the base 1, and a magnetic attraction part such as an iron sheet is installed on the fixing part 2 which can be attracted to the magnet. When the fixing part 2 approaches the base 1, the magnetic attraction will automatically pull the fixing part 2 to the correct position, quickly realizing the fixation.
[0043] Further, the side wall of the first positioning groove 11 close to the positioning column 13 is further provided with a limiting block 14 extending along the axial direction parallel to the positioning column 13, and the limiting block 14 is adapted to abut against the side wall of the inductor coil 3 when the inductor coil 3 is placed in the first positioning groove 11.
[0044] As can be easily understood, when the inductor coil 3 is placed in the first positioning groove 11, the limiting block 14 is in close abutment with the coil side wall, which provides additional lateral support and limiting for the coil. In the subsequent process of pressing the coil by knocking the fixing member 2 with a rubber hammer, even if subjected to a larger impact force, the coil will not roll or shift due to lateral force, and will always maintain in the predetermined ideal position, ensuring the accuracy and stability of the pressing operation. At the same time, since the limiting block 14 limits unnecessary movement of the coil, reduces the collision and friction with other parts of the jig due to the change of the coil position, reduces the risk of surface damage of the product, effectively improves the product yield, and further optimizes the entire processing flow.
[0045] In an optional embodiment, the limiting block 14 can be replaced by an elastic clamp. The elastic clamp is installed on the side wall of the first positioning groove 11 close to the positioning column 13, and the clamp material has a certain flexibility, such as rubber or silicone material. When the inductor coil 3 is put in, the elastic clamp will adaptively fit the coil side wall, giving a gentle and stable clamping force.
[0046] Further, the extension length of the limiting block 14 is less than the axial length of the positioning column 13.
[0047] As can be easily understood, the extension length of the limiting block 14 is less than the axial length of the positioning column 13, so that when the inductor coil 3 is placed in the first positioning groove 11, the limiting block 14 will not protrude too much to hinder the smooth placement of the coil, facilitating the operation.
[0048] Further, the groove wall of the first positioning groove 11 is adaptively matched with one end surface of the inductor coil 3, and the groove wall of the second positioning groove 21 is adaptively matched with the other end surface of the inductor coil 3.
[0049] As can be easily understood, the groove walls of the first positioning groove 11 and the second positioning groove 21 are adaptively matched with the two end surfaces of the inductor coil 3 respectively, which provides all-around and accurate adaptation for the coil. When placing the coil, the operator does not need to spend too much effort to adjust the coil position, and can quickly and accurately embed the coil into the positioning groove, improving the efficiency of the preliminary preparation work.
[0050] Further, the part of the end surface of the base 1 close to the edge is recessed inward to form a recessed groove 15, and the first positioning groove 11 is communicated to the outside of the base 1 through the recessed groove 15, and the recessed groove 15 is adapted to clamp the lead of the inductor coil 3.
[0051] Easily understandably, the first positioning groove 11 is communicated to the outside of the base 1 through the displacement slot 15, and provides a placement space for the lead wire of the inductor coil 3. When the coil is placed in the first positioning groove 11, the lead wire can be clamped into the displacement slot 15, effectively preventing the damage to the outer skin of the lead wire caused by the knocking process due to the lack of placement space, causing the risk of short circuit and the interference to the subsequent operation. Secondly, during the pressing process of the coil, the lead wire is fixed in the displacement slot 15 and will not be displaced or pulled due to external force impact, ensuring the stability of the connection part of the coil and the lead wire and reducing the possibility of coil damage or poor electrical performance caused by the pulling of the lead wire.
[0052] Although the embodiments of the present application are described in conjunction with the drawings, various modifications and changes can be made by those skilled in the art without departing from the spirit and scope of the present application, and such modifications and changes fall within the scope defined by the appended claims.
