[0016] The technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0017] In this document, terms such as “up,” “down,” “left,” “right,” and “top” indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are used only for the convenience of describing this utility model and simplifying the description, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0018] like Figures 1 to 3 As shown, a yoke clamp includes a connecting frame 1. Clamping columns are respectively provided on both sides of the bottom of the connecting frame 1. The distance between the two clamping columns is adjustable. The clamping columns include a first clamping column 2 and a second clamping column 3. The distance between the second clamping column 3 and the connecting frame 1 is adjustable. The bottom of the second clamping column 3 is threaded with a telescopic rod 4 for clamping the iron core.

[0019] By adjusting the distance between the two clamping columns connected to the connecting frame 1, when clamping iron cores of different thicknesses, the distance between the two clamping columns can be adjusted first to quickly adapt to the iron core size, and then the telescopic rod 4 can be adjusted to achieve stable clamping and fixation, and its clamping force on the iron core can be finely adjusted. The clamping columns adopt a split structure, and the distance between the second clamping column 3 and the connecting frame 1 can be adjusted to achieve adjustment of the clamping height, matching iron cores of different heights and achieving stable clamping. The above structure provides multi-dimensional adjustment capabilities, greatly improving the versatility and adaptability of the fixture.

[0020] With the above setup, a single clamp can meet the clamping requirements of various iron core specifications, reducing equipment costs. Meanwhile, the threaded telescopic rod 4 at the bottom provides precise fine-tuning of the clamping mechanism, ensuring clamping stability and reliability.

[0021] In the yoke clamp of this embodiment, the bottom of the connecting frame 1 is provided with a sliding groove 5, the top of the first clamping column 2 is provided with a slider 6, and a bidirectional threaded screw 7 is rotatably connected in the sliding groove 5. The two sliders 6 are respectively threaded to both sides of the bidirectional threaded screw 7.

[0022] Specifically, one end of the bidirectional threaded screw 7 extends to the outside of the connecting frame 1 and is equipped with an adjustment knob. Through the above-mentioned setting, the external adjustment knob provides the operator with a labor-saving and convenient point of force application. When the operator rotates the bidirectional threaded screw 7, the two sliders 6 will move synchronously towards or away from each other in the slide groove 5, thereby driving the two first clamping columns 2 to move closer or further away from each other. Through the above-mentioned synchronous movement, the distance between the clamping columns can be quickly adjusted, thereby quickly adapting to the size of the iron core, which is convenient for subsequent stable clamping by adjusting the telescopic rod 4.

[0023] Preferably, a connecting plate is provided in the middle of the slide groove 5, and the bidirectional threaded screw 7 is rotatably connected to the connecting plate. The connecting plate in the middle provides a stable intermediate support for the long screw, preventing it from bending and deforming due to its own weight or force, and ensuring that the slider 6 moves smoothly.

[0024] The above setup enables synchronous, symmetrical, continuous, and smooth distance adjustment of the two clamping columns. Employing a bidirectional threaded screw structure, only one operation (rotating the screw) is required to simultaneously control both clamping columns, resulting in high adjustment efficiency and ensuring a stable clamping center position with excellent alignment. The screw drive also features a self-locking function, automatically locking the position after adjustment to guarantee rigidity and stability during clamping and prevent loosening due to vibration or other reasons.

[0025] In the yoke clamp of this embodiment, the slider 6 is located in the middle of the top end face of the first clamping column 2, and the two sides of the end face are respectively attached to the bottom of the connecting frame 1 so that the connecting frame 1 can provide support for the first clamping column 2.

[0026] Specifically, the slider 6 is integrally formed with the first clamping post 2 and protrudes from the end face of the first clamping post 2. The two sides of the end face (i.e. the two sides of the slider 6) are respectively attached to the bottom plane of the connecting frame 1.

[0027] The above structure significantly enhances the support rigidity and torsional resistance of the first clamping column 2. When clamping the iron core, the clamping column will be subjected to lateral force. By attaching the top end face of the first clamping column 2 to the bottom of the connecting frame 1 on a large area, a stable surface contact support is formed, and the force is evenly transmitted to the connecting frame 1. This effectively prevents swaying or twisting caused by the cantilever structure, and ensures the clamping accuracy and the overall structural strength of the fixture.

[0028] In the yoke clamp of this embodiment, the bottom of the first clamping post 2 is provided with a plug-in groove 8, and the top of the second clamping post 3 is provided with a plug-in post 9. The plug-in post 9 matches the shape of the plug-in groove 8 and its height within the plug-in groove 8 is adjustable.

[0029] Specifically, the shapes of the plug-in post 9 and the plug-in slot 8 are matched (for example, both are rectangular cross sections), so that the plug-in post 9 can be inserted into the plug-in slot 8 and can slide up and down in it, thereby realizing the height adjustment of the second clamping post 3 relative to the first clamping post 2, and thus enabling the telescopic rod 4 to adapt to the clamping of iron cores of different heights.

[0030] The above configuration provides a simple, compact, and highly directional height adjustment solution. The plug-in connection ensures that the second clamping column 3 will not experience radial offset or rotation during lifting, resulting in a precise movement trajectory. This design saves space, making the clamp structure more compact while ensuring stable force transmission.

[0031] In the yoke clamp of this embodiment, a locking bolt 10 is threadedly connected to the plug post 9. The locking bolt 10 is located outside the plug post 9 and perpendicular to the plug post 9. A limit block is fixedly connected to the outer end of the locking bolt 10.

[0032] To achieve height adjustment and locking, a locking bolt 10 is threaded onto the plug-in post 9, and a limiting block for easy manual tightening is fixedly connected to the outer end of the locking bolt 10. Correspondingly, an adjustment groove 11 is provided vertically on the outer wall of the first clamping post 2. This adjustment groove 11 communicates with the internal plug-in groove 8, and the screw portion of the locking bolt 10 passes through this adjustment groove 11 and is threadedly connected to the plug-in post 9.

[0033] The above setup achieves a reliable height locking mechanism. When the second clamping column 3 is adjusted to a suitable height, simply tighten the locking bolt 10. The end of the bolt is screwed into the plug-in column 9, and under the action of the limiting block, the plug-in column 9 tightly presses against the inner wall of the plug-in groove 8. The limiting block and the plug-in column 9 clamp the side wall of the first clamping column 2 from both sides, firmly fixing the plug-in column 9 on the first clamping column 2, thereby achieving the fixation of the overall height of the clamping column.

[0034] The adjustment groove 11 not only provides space for the locking bolt 10 to move, but also intuitively displays the adjustment range, making it easy to operate. Furthermore, scale lines can be set on the edge of the adjustment groove 11 to facilitate the alignment of the height of the second clamping column 3 on both sides, so that the height of the clamping column on both sides is adjusted to be consistent.

[0035] In the yoke clamp of this embodiment, the bottom of the adjustment groove 11 is provided with a stop block for blocking the adjustment groove 11, and the bottom end face of the stop block is flush with the end face of the first clamping column 2.

[0036] The above-mentioned design optimizes the structural details and improves the practicality and safety of the clamp. The stop prevents the second clamping post 3 from driving the insertion post 9 and the locking bolt 10 out of the adjustment groove 11. At the same time, the flush design avoids protrusions or pits, making the contact end surfaces of the first clamping post 2 and the second clamping post 3 flat, so that they can fit stably when not elongated, adapting to the normal length of the clamping post.
