Description

Technical Field

[0001] The utility model relates to the field of inductor coil fixtures, in particular to an inductor coil testing fixture with good protection effect. Background Art

[0002] Inductor coil test fixtures are important tools specifically used to test the performance of inductor coils. They can measure key electrical parameters such as inductance value and quality factor to ensure the performance and stability of inductor coils in electronic equipment. These fixtures have different designs, but usually include components such as fixtures and measuring instruments to effectively clamp and accurately measure inductor coils. In order to ensure the quality of inductor coils and the overall performance and reliability of electronic equipment, inductor coil test fixtures play an indispensable role. Choosing a suitable test fixture is crucial for the research and development and production of electronic equipment.

[0003] Institute of Economic Inspection, application number: 202120166602.X, an inductor coil test fixture. In the comparative documents, a fixed cylinder and a fixed plate are used to internally support and limit the inductor coil to adapt to subsequent detection operations. However, there is a problem during its operation. Specifically, the movement form of the fixed cylinder pushing the fixed plate needs to be adjusted according to the inner diameter of the inductor coil. When using this fixture to limit multiple inductor coils in turn, frequent debugging makes the operation of the inductor coil more inconvenient, reducing the convenience of using the fixture. Utility Model Content

[0004] Based on this, the purpose of the utility model is to provide an inductor coil testing fixture with good protection effect, so as to solve the technical problem that the fixture in the prior art has an inconvenient way of limiting the inductor coil.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: an inductor coil testing fixture with good protection effect, comprising an electric push rod, a fixture body is arranged on the top of the electric push rod, the fixture body comprises a supporting sleeve, a sliding block is slidably connected to the inner side of the supporting sleeve, a movable ring is sleeved on the outer surface of the supporting sleeve, the outer side of the sliding block passes through the supporting sleeve through a sliding groove, and is fixedly connected to the movable ring, a first supporting arm and a second supporting arm are arranged on the outer side of the supporting sleeve, one end of the first supporting arm is rotatably connected to the supporting sleeve through a rotating shaft, one end of the second supporting arm is rotatably connected to the movable ring through a rotating shaft, a pressure plate is rotatably connected between the first supporting arm and the second supporting arm through a rotating shaft, a screw rod is threadedly connected to the central axis of the sliding block, and a motor is arranged at the bottom end of the screw rod.

[0006] By adopting the above technical solution, when multiple inductor coils need to be tested, the fixture shows significant beneficial effects. First, the motor is started, and the motor drives the lead screw to rotate. At the same time, since the lead screw is threadedly connected to the sliding block, the sliding block can move longitudinally under the limit of the sliding groove and drive the movable ring. As the movable ring moves upward, the first support arm and the second support arm rotate at an angle, pushing the pressure plate to expand outward to form a pointed cone structure.

[0007] Furthermore, the electric push rod and the motor are electrically connected to an external power source through a control center.

[0008] By adopting the above technical solution, this connection method realizes centralized control of the equipment, which is convenient for operation and management. Through the control center, the user can conveniently control the operation of the electric push rod and the motor, thereby improving the operating efficiency.

[0009] Furthermore, the slide grooves are provided with four groups, and the movable ring, the sliding block and the sliding block are all limitedly slidable through the slide grooves and the supporting sleeves.

[0010] By adopting the above technical solution, a stable limited sliding path is provided for the movable ring, the sliding block and the sliding block, which ensures the accuracy and stability of these components during the movement and prevents deviation or dislocation.

[0011] Furthermore, the first support arms, the pressure plates and the second support arms are each provided in four groups, and are arranged in an equidistant ring shape along the central axis of the support sleeve.

[0012] By adopting the above technical solution, a stable support structure is provided for the testing of the inductor coil. The four groups of components are arranged in an equidistant ring along the central axis of the support sleeve, ensuring uniform distribution of the supporting force and preventing the inductor coil from tilting or shifting during the test.

[0013] Furthermore, the transverse arc surface structure of the outer side surface of the pressure plate is used to adapt to the abutment of the inner curved surface of the inductor coil.

[0014] By adopting the above technical solution, the curved surface on the inner side of the inductor coil can be better adapted, the contact area between the pressure plate and the inner side of the inductor coil is increased, and a more stable support is provided.

[0015] Furthermore, a plurality of anti-slip teeth are provided on the surface of the pressure plate and are arranged linearly and equidistantly along the pressure plate.

[0016] By adopting the above technical solution, the inductor coil is effectively prevented from sliding during the test and affecting the accuracy of the test results. At the same time, the anti-slip teeth are arranged linearly and equidistantly along the pressure plate, which not only ensures the uniformity of the anti-slip effect, but also makes the overall structure more beautiful and regular.

[0017] In summary, the utility model mainly has the following beneficial effects:

[0018] 1. The utility model uses a fixture body. When multiple inductance coils need to be tested, first, the motor is started, and the motor drives the screw to rotate. At the same time, the screw is threadedly connected to the sliding block, pushing the sliding block and the movable ring to move longitudinally under the limit of the sliding groove. As the movable ring moves upward, the first support arm and the second support arm rotate, pushing the pressure plate to expand outward to form a pointed cone structure. The inductance coil can be directly placed on the pressure plate. With this structural support, the steps of accurately debugging the matching of the fixture and the inner diameter of the inductance coil in traditional operations are eliminated, which is convenient for the test operation of multiple inductance coils;

[0019] 2. The utility model sets a fixture body, and the second use form of the fixture of the utility model demonstrates its flexibility and wide applicability. First, by adjusting the rotating shaft, the four sets of pressure plates are placed in a vertical form. At the same time, these vertically placed pressure plates can directly abut and limit the inductor coil. This setting realizes the abutment and limiting function of the traditional fixture. This form not only retains the abutment ability of the fixture in the prior art, but also enhances the adaptability of the fixture to different external usage environments and working conditions. This flexibility allows the fixture to be quickly adjusted according to actual needs, thereby improving work efficiency and meeting diverse testing needs. BRIEF DESCRIPTION OF THE DRAWINGS

[0029] The following describes an embodiment of the utility model based on its overall structure.

[0030] Embodiment 1:

[0031] A test fixture for inductor coils with good protection effect, such as Figure 1-Figure 5As shown, it includes an electric push rod 1, a fixture body 2 is arranged on the top of the electric push rod 1, and the fixture body 2 includes a support sleeve 201, a sliding block 206 is slidably connected to the inner side of the support sleeve 201, and a movable ring 205 is sleeved on the outer surface of the support sleeve 201, and the outer side of the sliding block 206 passes through the support sleeve 201 through a sliding groove 208, and is fixedly connected to the movable ring 205, and a first support arm 202 and a second support arm 204 are arranged on the outer side of the support sleeve 201, one end of the first support arm 202 is rotatably connected to the support sleeve 201 through a rotating shaft, and one end of the second support arm 204 is rotatably connected to the movable ring 205 through a rotating shaft, and a pressure plate 203 is rotatably connected between the first support arm 202 and the second support arm 204 through a rotating shaft, and a screw rod 209 is threadedly connected at the central axis of the sliding block 206, and the screw rod 20 A motor 210 is provided at the bottom end of 9. When multiple inductance coils need to be tested, the fixture shows significant beneficial effects. First, the motor 210 is started, and the motor drives the screw rod 209 to rotate. At the same time, since the screw rod 209 is threadedly connected to the sliding block 206, the sliding block 206 can move longitudinally under the limit of the sliding groove 208 and drive the movable ring 205. As the movable ring 205 moves upward, the first support arm 202 and the second support arm 204 rotate at an angle, pushing the pressure plate 203 to expand outward to form a pointed cone structure. At this time, the inductance coil can be directly placed on the expanded pressure plate 203 and supported by this pointed cone structure. This method eliminates the complex steps required in traditional operations to accurately adjust the matching of the fixture and the inner diameter of the inductance coil, which greatly facilitates the testing operation of multiple inductance coils.

[0032] See also Figure 1 , Figure 2 , Figure 3 , Figure 4 The electric push rod 1 and the motor 210 are electrically connected to the external power supply through the control center. This connection method realizes centralized control of the equipment and is easy to operate and manage. Through the control center, the user can easily control the operation of the electric push rod 1 and the motor 210, thereby improving the operating efficiency. At the same time, the electrical connection with the external power supply ensures the stable power supply of the equipment, so that the electric push rod 1 and the motor 210 can work continuously and stably, thereby ensuring the reliability and stability of the test fixture, and facilitating the realization of automated control, improving production efficiency and test accuracy, and reducing the risk of human operating errors.

[0033] See also Figure 1 , Figure 2 , Figure 4 , Figure 5There are four groups of slide grooves 208. The movable ring 205, the sliding block 206 and the slider 207 are all limited and slidable through the slide grooves 208 and the support sleeve 201, providing a stable limited sliding path for the movable ring 205, the sliding block 206 and the slider 207, which ensures the accuracy and stability of these components during the movement and prevents deviation or misalignment. At the same time, the setting of four groups of slide grooves 208 increases the stability of the overall structure, makes the sliding process smoother, improves the working efficiency and durability of the equipment, and also helps to simplify the maintenance and maintenance of the equipment, because the movement trajectory of each component is clear and predictable, which is convenient for inspection and adjustment, thereby extending the service life of the equipment.

[0034] See also Figure 1 , Figure 2 , Figure 4 , Figure 5 , the first support arm 202, the pressure plate 203 and the second support arm 204 are each provided with four groups, and are arranged in an equidistant ring along the central axis of the support sleeve 201, providing a stable support structure for the test of the inductor coil. The four groups of components are arranged in an equidistant ring along the central axis of the support sleeve 201, ensuring the uniform distribution of the supporting force and preventing the inductor coil from tilting or shifting during the test. At the same time, this equidistant ring arrangement also optimizes the space utilization, making the fixture structure more compact and easy to carry and store. In addition, the equidistant arrangement also ensures the accuracy and repeatability of the test results, because the supporting force on the inductor coil in all directions is consistent, thereby improving the reliability and accuracy of the test.

[0035] Embodiment 2:

[0036] See also Figure 1 , Figure 2 , Figure 3 The horizontal arc surface structure of the outer side surface of the pressure plate 203 is used to adapt to the abutment of the curved surface on the inner side of the inductor coil, and can better adapt to the curved surface on the inner side of the inductor coil, increase the contact area between the pressure plate 203 and the inner side of the inductor coil, and provide more stable support. At the same time, the horizontal arc surface structure reduces the gap between the pressure plate 203 and the inductor coil, making the abutment tighter, effectively preventing the inductor coil from sliding or shifting during the test. This adaptability setting not only improves the accuracy and stability of the test, but also protects the inductor coil from damage, thereby extending its service life.

[0037] See also Figure 1 , Figure 2 , Figure 3 , Figure 4A plurality of anti-skid teeth 3 are arranged on the surface of the pressure plate 203, and are arranged equidistantly and linearly along the pressure plate 203, which effectively prevents the inductor coil from sliding during the test and affecting the accuracy of the test result. At the same time, the anti-skid teeth 3 are arranged equidistantly and linearly along the pressure plate 203, which not only ensures the uniformity of the anti-skid effect, but also makes the overall structure more beautiful and regular. In addition, the equidistantly arranged anti-skid teeth 3 also help to maintain the stability of the inductor coil and improve the reliability of the test. While improving the test accuracy, it also enhances the practicality and durability of the equipment.

[0038] The implementation principle of the utility model is as follows: when it is necessary to test multiple inductance coils, first, start the motor 210, so that the motor 210 drives the screw rod 209 to rotate, and at the same time, the screw rod 209 is threadedly connected with the sliding block 206, so that the sliding block 206 drives the outer movable ring 205 through the slider 207, and moves longitudinally under the limit of the slide groove 208. As the movable ring 205 gradually moves upward, the first support arm 202 and the second support arm 204 rotate at an angle and push the pressure plate 203 to expand outward. At this time, the four groups of first support arms 202, pressure plates 203 and second support arms can be rotated by rotating the rotating shaft. The arm 204 is in a pointed cone structure, and then the inductor coil can be directly placed on the outer side of the pressing plate 203, and supported by the overall pointed cone structure, which can avoid the need to accurately adjust the matching of the fixture and the inner diameter of the inductor coil in the traditional operation process, so as to facilitate the test operation of multiple inductor coils. At the same time, the overall size of the pointed cone can be adjusted by moving the longitudinal position of the sliding block 206 and the movable ring 205 to adapt to the test use of inductor coils with different inner diameters. In this fixture, since the direct limiting contact with the inductor coil is eliminated, the situation of inaccurate control of the pressing force in the traditional fixture is avoided, and its protection effect on the inductor coil is improved;

[0039] The utility model provides a second use form of the fixture, such as Figure 5 As shown, the pressure plates 203 are placed in a vertical form through the rotating structure of the rotating shaft, and the outer inductor coils are abutted and limited, so as to realize the abutment and limiting function in the traditional fixture, retain the abutment function of the fixture in the prior art, which is conducive to improving the applicability of the fixture to the external use environment and working conditions.

[0040] Parts not involved in the present invention are the same as the prior art or can be implemented by using the prior art, and will not be described in detail here.

[0041] Although an embodiment of the utility model has been shown and described, this specific embodiment is only an explanation of the utility model and is not a limitation of the utility model. The specific features, structures, materials or characteristics described may be combined in a suitable manner in any one or more embodiments or examples. After reading this specification, those skilled in the art may make modifications, substitutions and variations to the embodiments without creative contribution as needed without departing from the principles and purpose of the utility model.
