Description

Technical Field

[0001] The present application relates to the technical field of motor core molds, for example, to a testing device for detecting the bonding force between self-adhesive core sheets. Background Art

[0002] Self-bonding core sheets are usually made of multiple metal layers, including iron, silicon steel and other materials. These metal layers are bonded together through special self-bonding technology to form a solid whole. Compared with traditional core materials, self-bonding core sheets do not require the use of external adhesives or welding processes because they can achieve inter-layer bonding through their own adhesion. They are widely used in power transformers, mutual inductors and other electronic equipment.

[0003] The main method for testing the bonding force between the motor core pieces is to stick double-sided tape on both ends of the core, fix the core to the upper and lower ends of the dynamometer, and perform a pull-out test. Electromagnetic chucks are added to the upper and lower ends of the dynamometer, and the two ends of the core are adsorbed with magnetic force for a pull-out test. Both of these test methods are suitable for testing cores below 2000 Newtons, but are no longer applicable to self-bonding cores with a pull-out force of 10,000 Newtons between test pieces. Therefore, it is necessary to develop new test devices to achieve more accurate and reliable bonding force detection.

The workbench 1 is a test platform for the test device for the bonding force between self-bonded iron chips, which is used to carry a clamping device 2 and a hooking device 3 to detect the bonding force. The workbench 1 is provided with a clamping device 2 and a hooking device 3. When the bonding force of square or regular-shaped iron chips is detected, the clamping device 2 can ensure that the self-bonded iron chips maintain a stable position and direction during the bonding force test, thereby avoiding inaccurate test results caused by the movement or dislocation of the iron chip material. When the bonding force of circular or irregular-shaped iron chips is detected, the iron chips can be hooked by the hooking device 3. The hooking device 3 can usually be designed in a multi-functional and multi-model form, which can adapt to different needs and has strong applicability. In addition, the clamping device 2 and the hooking device 3 are designed to be detachable.

A protective component 8 is arranged on the outside of the vertical moving mechanism 4. The protective component 8 can frame the equipment clamping device 2 and the hook device 3 through the internal telescopic plate 83 to avoid the problem of accidental splashing of the iron chips during the test and protect the safety of the inspectors. In addition, the material of the protective component 8 is transparent, strong and soundproof, and the internal situation can be observed. Through the coordination of various device components, the detection accuracy and stability of the equipment are improved, and the scope of application of the detection is expanded.

[0173] The implementation principle of the test device for detecting the bonding force between self-bonding iron core sheets in the embodiment of the present application is as follows: when it is necessary to measure the bonding force between self-bonding iron core sheets, firstly, the corresponding clamping and fixing mechanism is selected according to the model or shape of the iron core sheet. When the bonding force of a square or regularly shaped iron core sheet is tested, firstly, the push rod 24 is driven to move by the hydraulic cylinder 26. The push rod 24 drives the upper clamping block 27 and the lower clamping block 23 to slide left and right inside the concave plate 22. The upper clamping block 27 and the lower clamping block 23 can clamp and fix the iron core sheet to ensure that the position will not shift. The iron core sheet is fixed by the clamping devices 2 correspondingly arranged above and below. The clamping device 2 can ensure that the self-bonding iron core sheet maintains a stable position and direction during the bonding force test, thereby avoiding inaccurate test results caused by movement or misalignment of the iron core sheet material. When testing the binding force of circular or irregularly shaped iron chips, the hook device 3 is symmetrically arranged with a pair of upper and lower hooks, and the special-shaped iron chips are tightened and fixed by the upper hook 36 and the lower hook 35. The hook device 3 can usually be designed in a multi-functional and multi-model form, which can adapt to different needs and has strong applicability. After the clamping and fixing mechanism is installed, the first motor 401 is started, and the first motor 401 drives the rotating shaft 402 to rotate, and the first screw rod 408 is driven to rotate through the first buckle block 403, the second buckle block 404 and the connecting shaft 406. The first screw rod 408 drives the moving seat 409 threadedly connected to the outside, and the moving seat 409 reciprocates, thereby realizing the vertical rise, fall or positioning of the upper part of the clamping device 2 and the hook device 3. Then the force measuring component 7 can be used to measure the magnitude of the binding force between the self-adhesive iron chips, including tension, pressure, shear force, etc., to help engineers and researchers understand the force conditions of the object. During the test, the protective component 8 of the transparent material covers the clamping and fixing mechanism, which increases the safety of the equipment. The operator reads and records the measured bonding force data through the display screen 71, and finally raises the protection component 8, takes out the measured self-adhesive iron chip, and completes the test.
