[0037] The positioning assembly 2 is installed on the top of the placement surface 101, and the positioning assembly 2 is provided with a positioning cavity 201 for accommodating the annular coil 4;

[0038] The clamping block 3 can be installed on the installation surface 102 so as to be movable up and down, and the lower surface of the clamping block 3 is the clamping surface, which is located directly above the positioning cavity 201; the edge of the clamping block 3 is recessed inwardly and is provided with an avoidance gap 301, and the avoidance gap 301 is used to avoid the lead 41 of the annular coil 4, and the lead 41 is bent upward and accommodated in the inside of the avoidance gap 301.

[0039] In the actual production process of toroidal coils, the bending operation of the lead wire is generally performed manually by assemblers who hold the toroidal coils in their hands, without any auxiliary tooling for positioning and precise bending, which is not conducive to improving the production efficiency and assembly accuracy of the toroidal coils.

[0040] In order to improve the production efficiency and assembly accuracy of the toroidal coil, the present technical solution proposes a lead bending tool for the toroidal coil, such as Figure 1-3 As shown, when the lead wire of the annular coil 4 is bent, the annular coil 4 is first positioned using the tool, and then the lead wire 41 is bent upward by avoiding the notch 301, which can effectively ensure the similarity of the bending operation of each annular coil 4. Figure 4 As shown, under the premise of ensuring the bending accuracy, the operation process of the assembler is simplified and the labor intensity is reduced.

[0041] Specifically, the use process of the lead bending tool of the present scheme includes the following steps: (1) moving the clamping block 3 upward so that there is space between the clamping block 3 and the placement surface 101 for installing the annular coil 4; (2) placing the annular coil 4 to be bent on the top of the placement surface 101, and installing it inside the positioning cavity 201, and moving the clamping block 3 downward to clamp the annular coil 4 to be bent; (3) bending the lead of the annular coil 4 upward manually or using auxiliary tools, and accommodating the bent lead 41 inside the avoidance gap 301; (4) moving the clamping block 3 upward again and releasing the clamping on the annular coil 4, removing the bent annular coil 4 from the top of the placement surface 101, and completing the bending step.

[0042] To further explain, the positioning assembly 2 includes at least two positioning blocks 21 , and the two positioning blocks 21 are respectively installed on two sides of the top of the placement surface 101 .

[0043] In a specific embodiment of the present technical solution, the positioning assembly 2 includes at least two positioning blocks 21, and the two positioning blocks 21 form a positioning cavity 201 for positioning and installing the annular coil 4, which has a simple structure, reliable performance, and is convenient for taking and placing the annular coil 4.

[0045] In a preferred embodiment of the present technical solution, the positioning assembly 2 of the present solution is detachably installed, which is conducive to adjusting the size of the positioning cavity 201 according to the annular coils 4 of different sizes, thereby improving the versatility of the lead bending tooling.

[0046] Further, it further comprises a sliding assembly 5, wherein the sliding assembly 5 comprises a sliding rail 51 and a sliding block 52;

[0047] The slide rail 51 is protrudingly mounted on the mounting surface 102, and the slide rail 51 extends vertically;

[0048] The shape of the clamping block 3 is L-shaped, and the slider 52 is protrudingly installed on the back side of the clamping block 3; a vertically extending slide groove is opened on the back side of the slider 52, and the slide groove is used to accommodate the slide rail 51, and the slider 52 can be installed on the slide rail 51 so as to be movable up and down through the slide groove.

[0049] In another preferred embodiment of the present technical solution, the clamping block 3 is mounted on the mounting surface 102 so as to be movable up and down through the sliding assembly 5 , which is beneficial to improving the movement stability of the clamping block 3 and ensuring that it has an effective clamping effect on the annular coil 4 .

[0050] Further, it further includes a driving assembly 6, the driving assembly 6 is mounted on the mounting surface 102, and the driving assembly 6 is located above the slide rail 51;

[0051] The output end of the driving component 6 is connected to the pressing block 3 , and the driving component 6 is used to drive the pressing block 3 to move up and down.

[0052] Furthermore, the lead bending tool of the present embodiment also includes a driving component 6, which drives the clamping block 3 to move up and down, thereby achieving effective clamping of the clamping block 3 on the annular coil 4 while saving effort.

[0053] To further illustrate, the driving assembly 6 includes a mounting seat 61, a driving rod 62, a transmission member 63 and a driving handle 64;

[0054] The mounting seat 61 includes a first mounting point and a second mounting point, and the second mounting point is located directly below the first mounting point;

[0055] The driving rod 62 is installed at the second installation point so as to be movable up and down, and the end of the driving rod 62 is the output end of the driving assembly 6, and the end of the driving rod 62 is connected to the pressing block 3;

[0056] The driving handle 64 includes a first hinge point and a second hinge point, and the first hinge point and the second hinge point are located at the same end of the driving handle 64, and the first hinge point is arranged outside the second hinge point; the first hinge point and the first mounting point are hinged to each other;

[0057] The transmission member 63 is arranged between the first mounting point and the second mounting point, and one end of the transmission member 63 is hinged to the second hinge point, and the other end of the transmission member 63 is hinged to the top end of the driving rod 62; the driving handle 64 drives the driving rod 62 to move up and down through the transmission member 63.

It has a simple structure and reliable performance, which is conducive to saving the space occupied by the lead bending tooling, and at the same time can play a labor-saving role in the process of tightening the annular coil 4.

[0059] Specifically, through the linkage of the mounting seat 61, the driving rod 62, the transmission member 63 and the driving handle 64, when the movable end of the driving handle 64 swings upward around the first hinge point, the driving rod 62 moves upward along the second mounting point, thereby driving the clamping block 3 to move upward along the slide rail 51; when the first hinge point of the movable end of the driving handle 64 swings downward, the driving rod 62 moves downward along the second mounting point, thereby driving the clamping block 3 to move downward along the slide rail 51.

[0060] To further explain, a vertically extending mounting through hole is formed at the second mounting point, and the driving rod 62 is mounted inside the mounting through hole so as to be movable up and down.

[0061] As a preference of the above embodiment, the second mounting point of the present solution is provided with a vertically extending mounting through hole, which is beneficial to improving the installation and movement stability of the driving rod 62 .

[0062] To further explain, the transmission members 63 include at least two, and the two transmission members 63 are symmetrical with respect to the moving direction of the driving rod 62; and the cross-section of the transmission member 63 is U-shaped.

[0063] As another preferred embodiment of the above embodiment, the two U-shaped transmission members 63 provided in this scheme are symmetrical about the moving direction of the driving rod 62, which is beneficial to avoid the up and down swinging of the driving handle 64 around the first hinge point and prevent the setting of the transmission member 63 from affecting the effective swinging of the driving handle 64.
