Description

Technical Field

[0001] This utility model relates to the field of iron core calibration technology, specifically an iron core calibration fixture. Background Technology

[0002] In electrical engineering terminology, the iron core refers to the core component that forms the magnetic circuit in electromagnetic equipment. Its core function is to guide and concentrate magnetic flux through high permeability materials, reduce magnetic leakage, and improve electromagnetic conversion efficiency. In the production process of electronic components such as transformers and inductors, the installation position and verticality of the iron core have a significant impact on product performance.

[0003] In existing technologies, core calibration mostly relies on manual operation and is carried out with the help of calibration fixtures. The calibration fixtures are generally equipped with support plates to support the core for calibration. However, the height of the support plates in existing fixtures is fixed, which makes it impossible to quickly fine-tune the height of the support plates and make accurate readings. This makes it difficult to meet the calibration requirements of high-precision and multi-specification cores, thus limiting the core calibration work. Utility Model Content

[0004] The purpose of this invention is to provide a core calibration fixture to solve the problems mentioned in the background art.

[0005] The objective of this utility model can be achieved through the following technical solutions:

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0024] A core calibration fixture, such as Figures 1-4 As shown, the fixture includes a base 1, which provides stable support for the entire fixture. A main body 2 is fixedly installed on the upper surface of the base 1. A support plate 3 is slidably connected to the outer wall of the main body 2. A vertical groove 19 is opened through the outer wall of the main body 2. A sliding plate 7 is slidably connected inside the vertical groove 19, and one end of the sliding plate 7 is fixedly connected to the support plate 3. A movable plate 6 is movably installed inside the main body 2. The support plate 3 is slidably connected to the main body 2 through the sliding plate 7 and the vertical groove 19, and can move up and down in the vertical direction to support the iron core to be calibrated. An adjustment mechanism is provided on the outer wall of the main body 2. The adjustment mechanism includes a lead screw 18 and a connecting rod 13. The lead screw 18 is rotatably connected to the outer wall of the main body 2, and the support plate 3 is inserted into the outer wall of the main body 2.

[0025] An inclined block 9 is provided inside the main body 2 and below the movable plate 6. One end of the connecting rod 13 is fixedly connected to the inclined block 9. A connecting plate 10 is fixedly connected to the bottom surface of the movable plate 6. The bottom end of the connecting plate 10 is slidably connected to the inclined block 9. When the inclined block 9 moves laterally under the drive of the connecting rod 13, the bottom end of the connecting plate 10 slides along the inclined surface of the inclined block 9. The bottom end of the connecting plate 10 does not separate from the inclined block 9, which can drive the connecting plate 10 to move vertically, so as to accurately adjust the height of the support plate 3.

[0026] The adjustment mechanism also includes a frame 14, which is fixedly installed on the outer wall of the main body 2. A limit slider 15 is slidably connected inside the frame 14. The limit slider 15 can move along the inside of the frame 14 with the lead screw sleeve 16, thus limiting the movement of the lead screw sleeve 16, allowing it to only translate and not rotate. This ensures that the lead screw sleeve 16 can slide smoothly along the outside of the lead screw 18. The lead screw sleeve 16 is sleeved on the outside of the lead screw 18. The bottom end of the limit slider 15 is fixedly connected to the lead screw sleeve 16. A connecting block 17 is fixedly connected to the outer wall of the connecting rod 13, and the upper end of the connecting block 17 is fixedly connected to the lead screw sleeve 16. When the lead screw 18 is rotated, it can drive the lead screw sleeve 16 to move. The limit slider 15 follows the lead screw sleeve 16 and slides along the inside of the frame 14, thus limiting the movement of the lead screw sleeve 16. The movement of position 6 allows the lead screw sleeve 16 to move only laterally. The lead screw 18 is made of steel or stainless steel, while the lead screw sleeve 16 is made of copper alloy. The difference in the coefficient of friction between the materials enhances the self-locking property of the lead screw sleeve 16. In addition, the threaded connection between the lead screw 18 and the lead screw sleeve 16 can be made of fine thread or trapezoidal thread to further improve the actual self-locking performance. This allows the lead screw 18 and the lead screw sleeve 16 to enter a self-locking state when the rotation of the lead screw 18 stops, effectively preventing the lead screw sleeve 16 from sliding and ensuring that the position is fixed. This ensures that after the rotation of the lead screw 18 stops, the lead screw sleeve 16 can be locked in its position, thereby locking the connecting rod 13 and the ramp block 9 in their positions, ensuring the stability of the support plate 3 after subsequent adjustment.

[0027] Slide rods 8 are fixedly installed inside the main body 2 near both sides. Limiting blocks 12 and supporting springs 11 are sleeved on the outside of the two slide rods 8. One end of each limiting block 12 is fixedly connected to the movable plate 6. The limiting blocks 12 and supporting springs 11 can provide buffering and restoring force when the movable plate 6 moves.

[0028] Specifically, when the lead screw 18 is rotated, the lead screw sleeve 16 can be moved, thereby causing the connecting rod 13 and the ramp block 9 to move horizontally. The inclined surface of the ramp block 9 pushes the connecting plate 10, which in turn causes the movable plate 6 to move up and down along the slide rod 8. The slide plate 7 follows the movable plate 6 and moves up and down along the vertical groove 19, thereby adjusting the height of the support plate 3. The limit block 12 and the support spring 11 installed on the movable plate 6 can provide buffering and restoring force when the movable plate 6 moves, ensuring smooth movement and accurate return.

[0029] A scale 4 is fixedly connected to the outer wall of the main body 2. The scale 4 has a scale 20 engraved on its outer wall. A pointer 5 is fixedly connected to the outer wall of the support plate 3. The pointer 5 works with the scale 4 and scale 20 on the main body 2 to visually read the current position of the support plate 3, thereby achieving accurate measurement and calibration of the core height.

[0030] In use, the adjustment mechanism is driven by rotating the lead screw 18, which moves the ramp block 9 horizontally. The inclined plane transmission pushes the movable plate 6 up and down, thereby adjusting the height of the support plate 3 and achieving fine-tuning of the position of the support plate 3. At this time, the pointer 5 and the scale 4 can display the height value in real time, so that the distance between the support plate 3 and the upper surface of the main body 2 can be precisely adjusted to adapt to the calibration work of iron sheets of different specifications and stacking heights. At this time, the iron sheet to be calibrated, or multiple stacked iron sheets, can be placed on the upper surface of the support plate 3. The iron sheets that are higher than the upper surface of the main body 2 are brushed away. The iron sheets remaining on the support plate 3 are the calibration completed. At this time, the staff can take them out and collect them. At the same time, the support spring 11 ensures the stability and reset function during the adjustment process.

[0031] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
