Description

Technical Field

[0001] This utility model relates to the field of test tube racks, and in particular to a test device for iron cores. Background Technology

[0002] As a key component of electrical equipment such as motors and transformers, the performance of the iron core directly affects the efficiency and reliability of the equipment. Therefore, the inspection process of the iron core is particularly important. Due to the small size and variety of iron core products, the current technology for inspecting the size and form and position tolerances of iron cores is all done manually, which is inefficient and affects the measurement accuracy.

[0003] Therefore, those skilled in the art have provided a detection device for iron cores to solve the problems mentioned in the background art. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a core testing device. This device, through a first clamp module and a second clamp module, as well as a first bidirectional threaded rod and a second bidirectional threaded rod, mounted on a base, can simultaneously measure the outer and inner diameters of the core. Furthermore, the distance between the first and second clamp modules can be adjusted to measure cores of different sizes, significantly improving testing efficiency. By using two measuring devices, a standard sample can be placed for comparison when measuring core data. When the test sample's data is obtained, the standard sample's data is used to determine whether the test sample is qualified. Simultaneously, standard data can be pre-set, and two cores can be measured simultaneously, maximizing testing efficiency.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a core testing device, comprising a workbench, on which two bases are fixedly mounted, each base having a sliding groove, each base having two first clamping modules, each of the four first clamping modules having a first slider at its bottom, each of the four first clamping modules being slidably mounted within the sliding groove, each of the four first sliders having a first threaded hole inside, and each pair of first clamping modules having a first bidirectional threaded rod rotatably mounted within it; two second clamping modules are mounted on each of the two bases, each of the four second clamping modules having a second slider at its bottom, each of the four second clamping modules being slidably mounted within the sliding groove, each of the four second sliders having a second threaded hole, and each pair of second clamping modules having a second bidirectional threaded rod rotatably mounted within it; each of the first clamping modules on one side of each of the two bases having a first laser rangefinder inside, each of the second clamping modules on one side of each of the two bases having a second laser rangefinder, and each of the second clamping modules on one side of each of the two bases having a reflective block;

[0006] Through the above technical solution, the device, with the first clamping module and the second clamping module, as well as the first bidirectional threaded rod and the second bidirectional threaded rod set on the base, can be used to simultaneously measure the outer diameter and inner diameter of the iron core, and the distance between the first clamping module and the second clamping module can be adjusted to measure iron cores of different sizes, which greatly improves the detection efficiency.

[0007] Furthermore, a second motor is provided on one side of each of the two bases, and a rotating shaft is provided at the output end of each of the two second motors. A second bidirectional threaded rod is fixedly provided on the rotating shaft of each of the two second motors.

Based on the specific embodiments of the present invention, all other specific embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0027] Reference Figure 1-3This utility model provides a specific embodiment of a core testing device, comprising a workbench 1, on which two bases 2 are fixedly mounted. Each base 2 has a sliding groove 3. Each base 2 has two first clamping modules 4. The bottom of each of the four first clamping modules 4 is provided with a first slider 17. The four first clamping modules 4 are slidably disposed within the sliding grooves 3. Each of the four first sliders 17 has a first threaded hole 16 inside. A first bidirectional threaded rod 10 is rotatably disposed within every two first clamping modules 4. Each base 2 has two second clamping modules 5. The bottom of each of the four second clamping modules 5 is provided with a second slider 18. The four second clamping modules 5 are slidably disposed within the sliding grooves 3. Each of the two sliders 18 has a second threaded hole 19. A second bidirectional threaded rod 11 is rotatably installed in each pair of second clamping modules 5. A first laser rangefinder 6 is installed inside the first clamping module 4 on one side of each of the two bases 2. A second laser rangefinder 7 is installed on the second clamping module 5 on one side of each of the two bases 2. A reflective block 14 is installed on the second clamping module 5 on one side of each of the two bases 2. This device, through the first clamping module and the second clamping module and the first bidirectional threaded rod and the second bidirectional threaded rod installed on the base, can be used to simultaneously measure the outer diameter and inner diameter of the iron core. The distance between the first clamping module and the second clamping module can be adjusted to measure iron cores of different sizes, which greatly improves the detection efficiency.

[0028] Reference Figure 2-4 Each of the two bases 2 has a second motor 8 on one side, and the output end of each second motor 8 has a rotating shaft 9. A second bidirectional threaded rod 11 is fixedly installed on the rotating shaft 9 of each of the two second motors 8. A horizontal plate 13 is fixedly installed on one side of each of the two bases 2, and a first motor 12 is fixedly installed on each of the two horizontal plates 13. The output end of each first motor 12 has a rotating shaft 9, and a first bidirectional threaded rod 10 is fixedly installed on the rotating shaft 9 of each of the two first motors 12. The motor-driven method is faster and more portable. Each of the four second sliders 18 has an opening 15 so that the second slider is not affected by the first bidirectional threaded rod. A display 21 is installed in front of each of the two bases 2 to display the measured iron core data more intuitively. A controller 20 is installed on the worktable 1 to control the operation of the four motors. A power supply 22 is installed on the worktable 1 to supply power to the device.

[0029] Working principle: The first clamping module 4 and the second clamping module 5 are set on each base 2. The two second clamping modules 5 on each base 2 are respectively equipped with a second laser rangefinder 7 and a reflector block 14. The first laser rangefinder 6 is set inside the first clamping module 4 on one side of each base 2. The iron core to be measured is placed in the first clamping module 4 and the second clamping module 5. The first motor 12 drives the first bidirectional threaded rod 10 to move the first clamping module 4. The second motor 8 drives the second bidirectional threaded rod 11 to move the second clamping module 5. After the iron core is clamped, the inner diameter and outer diameter of the iron core can be measured. The inner diameter of the iron core is detected by the first laser rangefinder 6. Let the height of the trapezoid on the top surface of the first clamping module 4 be X. Then the inner diameter of the iron core = measured distance + 2X. The outer diameter of the iron core is detected by the second laser rangefinder 7. Let the height of the triangle on the top surface of the second clamping module 5 be Y. Then the outer diameter of the iron core = measured distance - 2Y.
