It is only for the convenience of description and simplifying the operation, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation.

In addition, the terms "first" and "second" are only used for distinction in description and do not have special meanings.
[0036] Such as Figures 1 to 2As shown in the figure, this embodiment provides a connection strength detection tooling, which includes a first tooling body 1 and a second tooling body 2. The first tooling body 1 includes a first fixing member 11 and a first moving member 12. The second tooling body 2 includes a second fixing member 21 and a second moving member 22. The first tooling body 1 and the second tooling body 2 are symmetrically arranged along the third direction, and the first moving member 12 and the second moving member 22 are oppositely arranged and are respectively used to connect both ends of the workpiece to be detected. By applying a pulling force away from each other to the first fixing member 11 and the second fixing member 21 respectively through an external mechanism, the pulling force at the connection of the workpiece to be detected can be measured, and thus the connection strength at the connection of the workpiece to be detected can be analyzed and obtained.
[0037] It should be noted that, in this embodiment, the workpiece to be detected is composed of at least two magnetic cores bonded together, and the connection strength detection tooling provided in this embodiment is used to detect the connection strength between the magnetic cores. In other embodiments, the workpiece to be detected may also be at least two sub-workpieces connected by other connection methods, and the above connection methods include but are not limited to welding, magnetic connection or clamping, etc., which are not limited herein.
[0038] The existing connection strength detection tooling realizes the installation of the moving member and the fixing member through connectors such as bolts, which has problems such as complex structure, cumbersome disassembly and installation steps resulting in low detection efficiency, and since the position of the moving member relative to the fixing member is fixed and cannot be adjusted, once the position of the workpiece to be detected is offset when connected to the moving member, resulting in the workpiece to be detected deviating from the center position of the moving member, it will cause the force line of the workpiece to be detected to deviate from the force line of the pulling force provided by the external mechanism during the pulling detection, resulting in inaccurate detection results.
[0039] To solve the above problems, in this embodiment, the first moving member 12 is slidably arranged on the first fixing member 11 along the first direction, and the second moving member 22 is slidably arranged on the second fixing member 21 along the second direction, where the first direction, the second direction, and the third direction are perpendicular to each other in pairs. When the workpiece to be detected deviates from the center of the first moving member 12 and / or the second moving member 22, by adjusting the position of the first moving member 12 relative to the first fixing member 11 in the first direction and the position of the second moving member 22 relative to the second fixing member 21 in the second direction, the center of the workpiece to be detected can always be located on the center connection line of the first fixing member 11 and the second fixing member 21, so as to ensure that the force line of the workpiece to be detected coincides with the force line of the pulling force during pulling, and ensure the accuracy of the detection result.
[0040] Specifically, a first sliding groove 121 extending in a first direction is provided on one of the first fixing member 11 and the first movable member 12, and a first sliding protrusion 111 slidably engaged with the first sliding groove 121 is provided on the other. The sliding connection between the first fixing member 11 and the first movable member 12 is realized through the cooperation between the first sliding protrusion 111 and the first sliding groove 121. Similarly, a second sliding groove 221 extending in a second direction is provided on one of the second fixing member 21 and the second movable member 22, and a second sliding protrusion 211 slidably engaged with the second sliding groove 221 is provided on the other, which will not be elaborated here.
[0041] As Figure 2 shown, the first sliding protrusion 111 is provided on the first fixing member 11, and the first sliding groove 121 is provided on the first movable member 12, making the structure of the first movable member 12 compact and facilitating fixation during bonding. Similarly, the second sliding protrusion 211 is provided on the second fixing member 21, and the second sliding groove 221 is provided on the second movable member 22, which will not be elaborated here.
[0042] During pulling, in order to relatively fix the first fixing member 11 and the first movable member 12 in a third direction, the first sliding groove 121 is a trapezoidal groove or a T-shaped groove, and the shape of the first sliding protrusion 111 is adapted to the shape of the first sliding groove 121. The top width of the first sliding groove 121 is smaller than the bottom width, thereby restricting the displacement of the first sliding protrusion 111 in the third direction. Similarly, the second sliding groove 221 is a trapezoidal groove or a T-shaped groove, and the shape of the second sliding protrusion 211 is adapted to the shape of the second sliding groove 221, which will not be elaborated here.
[0043] Furthermore, the number of the first sliding grooves 121 is at least two, and at least two first sliding grooves 121 are arranged in parallel and spaced along the second direction. Each first sliding groove 121 corresponds to a first sliding protrusion 111, thereby providing stable guidance for the movement of the first movable member 12 along the first direction, avoiding the deviation of its movement path, ensuring that the first movable member 12 can slide smoothly, and limiting the first sliding protrusion 111 in the third direction through the two first sliding grooves 121 to ensure the firm connection between the first movable member 12 and the first fixing member 11. Similarly, the number of the second sliding grooves 221 is at least two, and at least two second sliding grooves 221 are arranged in parallel and spaced along the first direction. Each second sliding groove 221 corresponds to a second sliding protrusion 211, which will not be elaborated here.
[0044] In order to avoid damaging the workpiece to be detected, the connection between the workpiece to be detected and the first movable member 12 and the second movable member 22 is by bonding. After applying the bonding adhesive to the contact surfaces between the workpiece to be detected and the first movable member 12 and the second movable member 22, it is necessary to cure the bonding adhesive by high-temperature baking to prevent the workpiece to be detected from separating from the first movable member 12 and the second movable member 22 during the detection process.
[0045] The moving parts of the existing connection strength detection tooling are usually circular and prone to rolling during high-temperature baking. In this embodiment, the opposite surfaces of the first moving part 12 and the second moving part 22 are both polygonal, so that the first moving part 12 and the second moving part 22 are not easily displaced during transfer and baking.
[0046] Furthermore, the opposite surfaces of the first moving part 12 and the second moving part 22 are both square, so that the first moving part 12 and the second moving part 22 are not easily rolled, and at the same time, a sufficient bonding area can be maintained, which is convenient for bonding the workpiece to be detected to the central positions of the first moving part 12 and the second moving part 22.
[0047] After the detection is completed, the first moving part 12, the second moving part 22 and the workpiece to be detected can be separated by melting the bonding glue through high-temperature baking, realizing the reuse of the first moving part 12 and the second moving part 22, thereby reducing the detection cost.
[0048] In this embodiment, the side lengths of the opposite surfaces of the first moving part 12 and the second moving part 22 are 60 mm to 80 mm, which can be applied to the connection strength detection of almost all different specifications of magnetic cores in the prior art, improving the versatility of the connection strength detection tooling. Optionally, the workpiece to be detected can also be composed of other workpieces. According to the size of the workpiece to be detected, the side lengths of the opposite surfaces of the first moving part 12 and the second moving part 22 can be adjusted to be adapted to the largest-size workpiece to be detected in the prior art.
[0049] In addition, the connection strength detection tooling further includes a fixing assembly 3. Fixing assemblies 3 are provided on both the first fixing part 11 and the second fixing part 21. The first fixing part 11 and the second fixing part 21 are both connected to an external mechanism through the corresponding fixing assemblies 3, so as to facilitate the external mechanism to apply a pulling force in the third direction to separate the first fixing part 11 and the second fixing part 21 from each other.
[0050] Specifically, as Figure 1 shown, the fixing assembly 3 includes a connecting piece 31, a first locking piece 32 and a second locking piece 33. The first end of the connecting piece 31 is used to connect the first fixing part 11 or the second fixing part 21, the second end of the connecting piece 31 is used to connect the external mechanism, and both the first locking piece 32 and the second locking piece 33 are threadedly connected to the connecting piece 31. The first locking piece 32 is used to lock the first fixing part 11 or the second fixing part 21, and the second locking piece 33 is used to lock the external mechanism.
[0051] This embodiment further provides a connection strength detection device, which includes a frame, a tensile testing machine, and the above-mentioned connection strength detection tooling. The two ends of the component to be detected are respectively connected to the first movable member 12 and the second movable member 22. The first fixing member 11 is connected to the frame, and the second fixing member 21 is connected to the output end of the tensile testing machine and can move in a direction close to or away from the frame (i.e., the third direction) under the driving action of the tensile testing machine. Starting the tensile testing machine to drive the second fixing member 21 to move away from the frame can apply a pulling force to the component to be detected until the component to be detected is pulled apart. Recording the pulling force of the tensile testing machine when it is pulled apart can achieve the detection of the connection strength of the component to be detected.
[0052] Obviously, the above embodiments of the present invention are merely examples for clearly explaining the present invention, rather than limiting the implementation manners of the present invention. For those of ordinary skill in the art, various obvious changes, re-adjustments, and substitutions can be made without departing from the protection scope of the present invention. It is not necessary and impossible to enumerate all the implementation manners here. Any modifications, equivalent substitutions, and improvements made within the spirit and principle of the present invention shall be included in the protection scope of the claims of the present invention.
