Technical Field

[0001] This disclosure relates to the field of ACB testing technology, and in particular to ACB characteristic testing unit mechanisms. Background Technology

[0002] ACB refers to a frame circuit breaker, an instrument used for segmenting current. It is a mechanical switching electrical appliance that can connect, carry, and segment current under normal circuit conditions, as well as connect, carry, and segment current for a certain time under specified abnormal circuit conditions. Currently, ACBs need to be tested during the production process to determine their performance.

[0003] However, current methods for testing the tripping force of the ACB frame still rely on manual testing and simple force feedback. Furthermore, the drive mechanism primarily uses built-in components for detection, which can lead to damage and prevent the implementation of large-scale testing. Therefore, those skilled in the art have provided an ACB characteristic detection unit mechanism to address the problems mentioned in the background. Summary of the Invention

[0031] The technical solution of the present invention will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0032] The components of the embodiments of the invention described and shown in the accompanying drawings can typically be arranged and designed in a variety of different configurations. Therefore, the following detailed description of the embodiments of the invention provided in the drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention.

[0033] The ACB characteristic detection unit mechanism includes a base plate 7 and a mounting bracket 4 mounted on the upper surface of the base plate 7. A Y-axis transfer module 2 slides on the upper surface of the mounting bracket 4, and an X-axis transfer module 21 is mounted on the rear surface of the mounting bracket 4. A Z-axis electric cylinder module 1 is mounted on one side of the Y-axis transfer module 2, and a pressure sensor 11 is connected to the telescopic end of the Z-axis electric cylinder module 1.

[0034] The upper surface of the base plate 7 is provided with a small mechanism detection mechanism and a large mechanism detection mechanism from left to right, and the small mechanism detection mechanism and the large mechanism detection mechanism have the same structure.

[0035] The large mechanism testing mechanism includes a V-shaped shaft drive mechanism 6 installed on the upper surface of the base plate 7, and a cantilever pin mechanism 8 is installed on the upper surface of the base plate 7 behind the V-shaped shaft drive mechanism 6. A connecting rod fixing mechanism 5 is provided above the cantilever pin mechanism 8.

[0036] exist Figure 1 and Figure 7 In the middle: the connecting rod fixing mechanism 5 includes a connecting fixing cylinder 51 installed above the cantilever pin mechanism 8. The telescopic end of the connecting fixing cylinder 51 is connected to a first telescopic rod 53. One end of the first telescopic rod 53 is connected to a clamping plate 52. Large rotating shaft clamping cylinders 10 are symmetrically arranged on both sides of the clamping plate 52. The telescopic end of the large rotating shaft clamping cylinder 10 is connected to a cam roller clamping plate 101. The large rotating shaft clamping cylinder 10 can make the cam roller clamping plate 101 clamp the product rotating shaft, which can prevent bending deformation caused by the radial torque of the rotating shaft. Furthermore, the cam can effectively clamp the product, and since the cam can rotate, it will not damage the product.

[0037] exist Figure 1 and Figure 5 In the middle section: The V-shaft drive mechanism 6 includes a servo motor 61 mounted above the base plate 7. The drive end of the servo motor 61 is connected to a worm gear reducer 62, and the transmission end of the worm gear reducer 62 is connected to a dynamic torque sensor 64. A torque sensor coupling 65 is mounted at the front end of the dynamic torque sensor 64. A slot is opened on the outside of the torque sensor coupling 65, and a coupling lever 63 is mounted inside the slot. The product to be tested is mounted above the base plate 7 in front of the cantilever pin mechanism 8. A V-shaft is mounted on one side of the product to be tested. The rotating end of the V-shaft drive mechanism 6 is connected to the V-shaft. The dynamic torque sensor 64 in the V-shaft drive mechanism 6 can support wireless rotation of the V-shaft in one direction. At the same time, the worm gear reducer 62 can prevent the reverse rotation caused by the slippage of the product from damaging the servo motor 61. The servo motor 61 can accurately test the rotation angle and initial position of the V-shaft. Furthermore, the coupling lever 63 and the torque sensor coupling 65 can freely release the energy stored in the product without limiting the power value.

[0038] exist Figure 3 and Figure 4 The cantilever pin-threading mechanism 8 includes a first fixed plate 85 mounted on the base plate 7. A first cylinder 81 is mounted above the first fixed plate 85. A proportional valve 82 is mounted at the rear end of the first cylinder 81. A cantilever hanger 84 is connected to the telescopic end of the first cylinder 81. A mounting plate is mounted above the base plate 7 and below the first cylinder 81. A first bracket 83 is mounted on the upper surface of the mounting plate on one side of the first cylinder 81. The cantilever hanger 84 is rotatably connected to the first bracket 83. A large rotating shaft 9 is mounted in front of the cantilever pin-threading mechanism 8. Cantilever pin hangers are symmetrically arranged on the outside of the large rotating shaft 9. The cantilever pin hangers are of two types: 3P and 4P. The cantilever hangers 84 in the cantilever pin-threading mechanism 8 can accurately provide feedback on product performance and data. At the same time, the proportional valve 82 is connected to the end of the first cylinder 81. The proportional valve 82 can precisely adjust the operating pressure of the first cylinder 81, thereby providing a better buffer force for the V-shaft. This allows for rapid response and automatic control for different products and models.

[0039] The working principle and usage process of this invention: When performing ACB testing, the product to be tested is first placed in the test position. After placement, the product can be fixed and clamped by the connecting rod fixing mechanism 5. During operation, the connecting fixing cylinder 51 will cause the first telescopic rod 53 to extend and retract, and the clamping plate 52 will clamp the product.

[0040] After clamping, the cantilever pin mechanism 8 inserts the pin into the cantilever pin mounting hole of the product. When the first cylinder 81 is working, the cantilever mounting plate 84 rotates. When the cantilever mounting plate 84 rotates, it rotates with the first bracket 83. After rotation, the cantilever mounting plate 84 is inserted into the cantilever pin mounting hole of the product for use. This can accurately provide feedback on product performance and data. At the same time, the end of the first cylinder 81 is connected to a proportional valve 82. The proportional valve 82 can precisely adjust the operating pressure of the first cylinder 81, thereby providing a better buffer force for the V-shaft. This allows for rapid response and automatic control for different products and models.

[0041] The large rotating shaft clamping cylinder 10 can make the cam roller clamping plate 101 hold the product rotating shaft tightly, which can prevent bending deformation caused by the radial torque of the rotating shaft. The cam setting can effectively hold the product, and since the cam can rotate, it will not damage the product.

[0042] The rotating end of the V-shaft drive mechanism 6 is connected to the V-shaft of the product. The V-shaft drive mechanism 6 can be used to drive the V-shaft of the product. The dynamic torque sensor 64 in the V-shaft drive mechanism 6 can support wireless rotation of the V-shaft in one direction. At the same time, the worm gear reducer 62 can prevent the reverse rotation caused by the slippage of the product from damaging the servo motor 61. The servo motor 61 can accurately test the rotation angle and initial position of the V-shaft. The coupling lever 63 and the torque sensor coupling 65 can freely release the energy stored in the product without limiting the power value.

[0043] Finally, the servo-driven release force testing mechanism goes to the product's opening and closing points to perform pressing operations, thus reading data. Specifically, the Z-axis electric cylinder module 1, Y-axis transfer module 2, and X-axis transfer module 21 can move the pressure sensor 11 at the lower end of the cylinder in the Z-axis electric cylinder module 1. The pressure sensor 11 can then be used to test the product's tripping force, closing force, and other data such as force and stroke values, effectively improving testing efficiency. After the above processes are completed, the device returns to its original position, and the product is removed, thus completing the product testing.
