Description

Technical Field

[0001] This utility model relates to the field of coil testing technology, and in particular to a coil testing device. Background Technology

[0002] As a key component in electrical equipment, the performance of coils directly affects the overall stability and safety of the machine. Currently, coil testing typically includes electrical performance testing (such as resistance, insulation resistance, and withstand voltage) and environmental adaptability testing (such as insulation performance after immersion in water). Existing coil testing equipment is mostly designed for a single operating condition, meaning it can only perform dry or wet testing. Changing the testing environment often requires replacing testing fixtures or performing drainage or water injection operations, which are cumbersome and inefficient.

[0003] Furthermore, existing equipment often uses rigid clamping structures when fixing coils of different sizes and specifications, lacking buffering and adjustment capabilities. This can easily cause damage to the coil surface or result in insecure clamping, affecting test accuracy. Additionally, the spatial layout of the probe mechanism and positioning posts is not entirely rational, leading to insufficient equipment compactness, a large footprint, and hindering automated continuous testing.

[0004] In summary, there is a need for a coil testing device with a compact structure, adjustable clamping flexibility, and support for rapid switching between dry and wet operating conditions to improve testing efficiency and adaptability. Utility Model Content

[0005] In view of the shortcomings of the existing technology, this utility model provides a coil testing device, which aims to solve the above problems.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a coil testing device, comprising a body and a positioning column, wherein the body is provided with a lifting water tank inside, and a hanging basket for mounting the positioning column is provided at the top of the body. Symmetrical upright plates are provided on the left and right sides of the top of the body near the hanging basket. A flexible clamping and fixing mechanism is installed on the upright plate, which is used to adapt to coils of different specifications and sizes to be tested on the positioning column. A sliding component is also provided on the upright plate, and a probe mechanism is connected to the upright plate through the sliding component.

[0007] Furthermore, the bottom wall of the hanging basket is provided with several water-permeable holes, which are used to cover the positioning columns inside the hanging basket when the water level of the lifting water tank is raised.

[0008] Furthermore, the flexible clamping and fixing mechanism includes an electric push rod, a spring rod, and a clamping block. The electric push rod is mounted on the upright plate, and the piston end of the electric push rod passes through the upright plate and is connected to the spring rod. The end of the spring rod away from the upright plate is connected to the clamping block.

[0009] Furthermore, the sliding assembly includes a slide rail, a slider, and a horizontal plate. The slide rail is fixedly mounted on the top of the vertical plate, the sliders are symmetrically mounted on the left and right ends of the bottom wall of the horizontal plate, and the horizontal plate is slidably connected to the slide rail via the sliders.

[0010] Furthermore, the probe mechanism includes a probe body, a connecting rod, and an electric cylinder. The probe body is connected to the electric cylinder via the connecting rod, and the electric cylinder is mounted on the top of the horizontal plate.

[0011] Furthermore, the lifting water tank includes a water tank body and a folding lifting frame. The water tank body is installed inside the machine body via the folding lifting frame and is located directly below the hanging basket.

[0012] The beneficial effects of this utility model are as follows: The probe mechanism is mounted on the test slot above the gantry frame, saving space. The positioning column is also mounted on the gantry frame and located directly below the probe structure. The probe mechanism and the positioning column are connected to the gantry frame through two sets of lifting components. In use, the probe mechanism is first lowered into the test slot, and then its height is lowered again for contact detection. This method allows the probe to be raised and replaced after one coil terminal test is completed, eliminating the need for drainage. The partitioned arrangement of the water tank, positioning column, and probe makes the overall structural space layout more reasonable and its practicality relatively strong.

[0013] 1. In this utility model, by setting up a spatial structure layout of a ground-lifting water tank, a hanging basket, and a probe mechanism, the detection needs of both underwater and flying underwater working conditions can be met.

[0014] 2. In this utility model, by setting a ground-lifting water tank directly below the hanging basket, flexible adjustments can be made. When the water tank body is at its lowest point, the hanging basket and the positioning columns installed inside it are suspended in the air for testing. When the water tank is lifted to its highest point by the folding lifting frame, the hanging basket and the positioning columns inside it are passively immersed into the water tank body. The water inside the water tank body is immersed into the hanging basket through the water permeable holes, which can be used to test the immersion condition. The adjustment and use are flexible and convenient, solving the problem that switching between the two testing conditions is relatively inconvenient in the prior art.

[0015] 3. In this utility model, when the positioning column is clamped and fixed by the flexible clamping and fixing mechanism, the spring rod plays a flexible buffering role in the middle, which makes it adaptable to fixing coil structures of various sizes and types. It has strong applicability and has certain use value and promotion value. Attached Figure Description

[0022] like Figure 1 , 2As shown, a coil testing device includes a body 100 and a positioning column 200. The body 100 has a lifting water tank 10 inside. The top of the body 100 has a hanging basket 20 for mounting the positioning column 200. The top of the body 100 has symmetrical upright plates 30 on the left and right sides near the hanging basket 20. The upright plates 30 are equipped with flexible clamping and fixing mechanisms 40. The flexible clamping and fixing mechanisms 40 are used to adapt to coils of different specifications and sizes that need to be tested on the positioning column 200. The upright plates 30 are also equipped with sliding components 50. The upright plates 30 are connected to a probe mechanism 60 through the sliding components 50.

[0023] As one implementation method, the bottom wall of the hanging basket 20 is provided with several water-permeable holes 21, which are used to cover the positioning column 200 inside the hanging basket 20 when the water level of the lifting water tank 10 is raised.

[0024] In one embodiment, the flexible clamping and fixing mechanism 40 includes an electric push rod 41, a spring rod 42, and a clamping block 43. The electric push rod 41 is mounted on the upright plate 30, and the piston end of the electric push rod 41 passes through the upright plate 30 and is connected to the spring rod 42. The end of the spring rod 42 away from the upright plate 30 is connected to the clamping block 43.

[0025] As one implementation method, the clamping block 43 is an arc-shaped panel, which can better fit the coil structure to be fixed, making it more targeted.

[0026] In one embodiment, the sliding assembly 50 includes a slide rail 51, a slider 52, and a horizontal plate 53. The slide rail 51 is fixedly disposed at the top of the vertical plate 30, the slider 52 is symmetrically disposed at the left and right ends of the bottom wall of the horizontal plate 53, and the horizontal plate 53 is slidably connected to the slide rail 51 through the slider 52.

[0027] In one embodiment, the probe mechanism 60 includes a probe body 61, a connecting rod 62, and an electric cylinder 63. The probe body 61 is connected to the electric cylinder 63 via the connecting rod 62, and the electric cylinder 63 is mounted on the top of the horizontal plate 53.

[0030] The working principle of this utility model is as follows: When in use, the coil to be tested is installed on the positioning column 200. By controlling the electric push rod 41 in the flexible clamping and fixing mechanism 40 on both sides of the upright plate 30, the spring rod 42 and the clamping block 43 are pushed to achieve flexible clamping of the coil. Spring rod 42 provides a buffering effect, adapting to coils of different sizes and avoiding damage; Dry state testing: The lifting water tank 10 is in a lowered state, the water tank body 11 is located below the hanging basket 20, the coil is in the air, and the probe mechanism 60 drives the probe body 61 to move down through the electric cylinder 63 to contact the coil terminal for electrical testing; Wet state testing: The water tank body 11 is raised to the highest position through the folding lifting frame 12, and water flows through the water-permeable holes 21 at the bottom of the hanging basket 20 to immerse the positioning column 200 and the coil, simulating the immersion condition, and then electrical testing is performed; The horizontal plate 53 moves horizontally along the slide rail 51 through the slider 52 to adjust the lateral position of the probe mechanism 60; The electric cylinder 63 controls the vertical movement of the probe body 61 to achieve precise docking with the coil terminal; After completing the test of a coil, the probe mechanism rises and the water tank descends. If it is a wet state test, the next coil can be replaced without drainage, which significantly improves the testing efficiency.
