Description

Technical Field

[0002] The amorphous core is a part of an amorphous alloy transformer. There are many shapes of the amorphous core, and its cross section can be rectangular or circular. The amorphous core with a circular cross section is specifically a circular column structure.

[0003] At present, the processing technology of the amorphous core with a circular column structure is to use a fixture and then wind the amorphous tape into the fixture to achieve the processing effect. The existing fixture structure includes a main body and three rings. The three rings are distributed in a circular array on the outside of the main body. The amorphous tape is wound on the outer surface of the ring. The ring and the main body are hinged. By adjusting the axial position of the main body, the imaginary circumscribed circle formed by the ring (the inner diameter of the amorphous core) can be enlarged or reduced to meet the processing requirements of different sizes. However, the problem with this structure is that the ring and the main body are hinged, and the fixing of the ring is unstable during the processing. The ring is prone to local displacement, which causes the entire amorphous core to deviate during the processing, affecting the processing accuracy. Utility Model Content

At this time, the sleeve is in a constant state, and then the amorphous iron core is processed by winding the amorphous tape onto the sleeve. After the processing is completed, the driving shaft moves in the opposite direction, so that the first inclined surface and the second inclined surface move in the opposite direction, and the interference fit between the sleeve and the second slider is cancelled.

[0040] Example 1

[0041] This embodiment provides a clamping mechanism for an amorphous core, as shown in the attached Figure 1-5 As shown, including:

[0042] The limiting plate 11 is located on the side close to the fixed object, where the fixed object is specifically the entire clamping mechanism connected to the fixed object to form a supporting and fixing effect. A rotating mechanism can also be provided on the fixed object, and the rotating mechanism can drive the entire clamping mechanism to rotate to form a winding process of the amorphous strip. This structure is irrelevant to this embodiment, so it is not reflected in the accompanying drawings. Taking the accompanying drawings as an example, the fixed object is located on the right side of the limiting plate 11. The limiting plate 11 is provided with a first through hole 111 and a second through hole 112. The first through hole 111 is located at the center of the limiting plate 11, and the number of the second through holes 112 is adjusted according to actual needs. Here, the second through holes 112 are distributed in a circular array on the outside of the first through hole 111.

[0043] The drive shaft 12 has one end passing through the first through hole 111, so that the drive shaft 12 can have a larger stroke. Taking the accompanying figure as an example, the right end of the drive shaft 12 passes through the first through hole 111, and the rest of the drive shaft 12 is located on the left side of the limit plate 11. The drive shaft 12 forms an axial movement effect.

[0044] The connecting sleeve 13 is sleeved on the driving shaft 12, and the driving shaft 12 drives the connecting sleeve 13 to move axially. Here, the driving shaft 12 can be linked with the connecting sleeve 13. The driving shaft 12 itself moves axially, and the movement effect of the connecting sleeve 13 is achieved by the driving of the driving shaft 12. In addition, the driving shaft 12 can also form a screw transmission structure with the components on the right side of the limit plate 11 to convert the radial rotation force of the driving shaft 12 into the force of axial movement. In this structure, the connecting sleeve 13 will not rotate with the radial rotation of the driving shaft 12, and the connecting sleeve 13 will only perform an axial movement. The screw transmission structure is a prior art, so the components on the right side of the limit plate 11 are not shown in the attached drawings.

[0045] The first slider 14, the number of the first sliders 14 can be selected according to actual needs. The first sliders 14 are distributed in a circular array on the outside of the connecting sleeve 13. In this embodiment, the number of the first sliders 14 is four, and the four first sliders 14 are distributed in a circular array, and the first slider 14 is linked with the connecting sleeve 13, that is, when the connecting sleeve 13 moves axially, it drives the first slider 14 to move axially. The axial movement in this embodiment is specifically movement along the central axis of the drive shaft 12. The inner side surface of the first slider 14 cooperates with the connecting sleeve 13 to form a linkage effect. The outer side surface of the first slider 14 is provided with a first inclined surface 141, and the outer side surface of the first slider 14 here is specifically the surface away from the side of the connecting sleeve 13.

[0046] The second slider 15, the second through hole 112 at one end of the second slider 15 cooperates with the limiting plate 11, and the cooperation here specifically forms the axial fixation of the second slider 15 to prevent the second slider 15 from moving in the axial direction. The axial direction here also means moving along the central axis of the drive shaft 12. The other end of the second slider 15 is provided with a second inclined surface 151 that cooperates with the first inclined surface 141. When the first slider 14 moves axially, the first inclined surface 141 cooperates with the second inclined surface 151 to form a beveling force that drives the entire second slider 15 to move radially, and the radial direction here is the radial extension direction of the drive shaft 12. The second inclined surface 151 is located on the inner side of the second slider 15. The outer side surface of the second slider 15 is a plane. The outer side surface of the second slider 15 is specifically used to cooperate with the sleeve to form the fixing effect of the sleeve. In this embodiment, the number of the second sliders 15 is the same as the number of the first sliders 14, which is also four, so the number of the second through holes 112 is also four. The second through holes 112 form the limit of the second slider 15 in the radial direction. Here, the range of movement of the second slide block 15 is associated with the size of the second through hole 112 .

[0047] With this structural setting, during use, a sleeve of a circular column is sleeved on the second slider 15, so that the inner wall of the sleeve cooperates with the outer side of the second slider 15, the drive shaft 12 drives the connecting sleeve 13 to move axially, and the connecting sleeve 13 and the first slider 14 are also linked. The first inclined surface 141 cooperates with the second inclined surface 151 to make the second slider 15 move radially outward, forming an outward supporting action, until the outer side of the second slider 15 is clamped with the inner wall of the sleeve to form an interference fit. At this time, the sleeve is in a constant state, and then the amorphous iron core is processed by winding the amorphous tape onto the sleeve. After the processing is completed, the drive shaft 12 moves in the opposite direction, so that the first inclined surface 141 and the second inclined surface 151 move in the opposite direction, and the interference fit between the sleeve and the second slider 15 is cancelled. At this time, the amorphous iron core can be cancelled. This structure forms a tightening effect through interference fit, so that the sleeve will not be deformed by force during the processing process, thereby improving the processing accuracy. Here, the amorphous iron core and the sleeve are detachable. The sleeve may be made of metal, such as steel or iron, or other materials.

[0048] Specifically, as attached Figure 3As shown, one of the first slider 14 and the second slider 15 is provided with a slide groove 16, and the other of the first slider 14 and the second slider 15 is provided with a convex strip 17 that cooperates with the slide groove 16. The cooperation between the slide groove 16 and the convex strip 17 forms a clamping and guiding effect to prevent the movement trajectory from deviating. When the first slider 14 is provided with a slide groove 16, the second slide groove 16 is provided with a convex strip 17; conversely, when the first slider 14 is provided with a convex strip 17, the second slider 15 is provided with a slide groove 16. In this embodiment, the first inclined surface 141 is provided with a convex strip 17, and the second inclined surface 151 is provided with a slide groove 16. In addition to this embodiment, the first slider 14 and the second slider 15 can also directly form a bevel effect through the cooperation of the inclined surfaces, and drive can be achieved without guidance.

[0049] Specifically, the surface where the slide groove 16 and the convex strip 17 cooperate is an arc surface. The setting of the arc surface reduces friction resistance and makes adjustment more convenient. In this embodiment, the cross section of the convex strip 17 includes an arc to improve the overall sliding effect. Here, the slide groove 16 is also set as an arc surface.

[0050] Specifically, as attached Figure 3 As shown, one of the first slider 14 and the second slider 15 is provided with a guide groove 18, and the other of the first slider 14 and the second slider 15 is provided with a guide protrusion 19 that cooperates with the guide groove 18. The guide groove 18 cooperates with the guide protrusion 19 to further improve the guiding effect. When the first slider 14 is provided with the guide groove 18, the second slider 15 is provided with the guide protrusion 19; conversely, when the first slider 14 is provided with the guide protrusion 19, the second slider 15 is provided with the guide groove 18. In this embodiment, the guide groove 18 connects the convex strip 17 and the first inclined surface 141, and the guide groove 18 is located between the two to form a similar concave structure, and the guide protrusion 19 is located at the top of the slide groove 16 to form a shrinking structure. Therefore, the guide groove 18 cooperates with the guide protrusion 19 to form a clamping effect, and the first slider 14 and the second slider 15 are connected and fixed, and can only move along the inclined surface direction, and cannot slide in other directions.

[0051] Specifically, as attached Figure 1-4 As shown, the connecting sleeve 13 and the first slider 14 are provided with fixing holes 20, and the connecting sleeve 13 and the first slider 14 are provided with fixing feet 21 that match the fixing holes 20. The setting of the fixing holes 20 and the fixing feet 21 makes the connection between the connecting sleeve 13 and the first slider 14 more secure. When the connecting sleeve 13 is provided with the fixing holes 20, the first slider 14 is provided with the fixing feet 21; conversely, when the connecting sleeve 13 is provided with the fixing feet 21, the first slider 14 is provided with the fixing holes 20. In this embodiment, the number of the fixing holes 20 is two, and at the same time, the number of the fixing feet 21 is also two, which improves the connection and fixing effect between the two.

[0052] Specifically, the connecting sleeve 13 and the first slider 14 are connected by welding. The welding connection forms an integrated structure between the connecting sleeve 13 and the first slider 14. Here, the connecting sleeve 13 can first form a positioning and fixing effect with the first slider 14, and then increase the connection strength between the two by welding. In addition, the connecting sleeve 13 and the first slider 14 can also be connected and fixed by bolts or other methods.

[0053] Specifically, as attached Figure 1-4 As shown, two sets of sliding components 22 are provided at one end of the second slider 15. The two sets of sliding components 22 are arranged in parallel and spaced apart, and a gap is formed between the two sets. When the second slider 15 cooperates with the limiting plate 11, the two sets of sliding components 22 are respectively located on both sides of the limiting plate 11 and abut against the limiting plate 11, that is, one set of sliding components 22 abuts against the left side of the limiting plate 11, and the other set of sliding components 22 abuts against the right side of the limiting plate 11. The two sets of sliding components 22 form the effect of clamping the limiting plate 11, so that the second slider 15 can only move radially, increase the fitting area between the second slider 15 and the sleeve, and make the force uniform. In this case, the sliding component 22 includes a pin 221 and two rotating members 222. The two rotating members 222 are respectively located on both sides of the second slider 15. The pin 221 passes through one of the rotating members 222, the second slider 15, and the other rotating member 222, forming the effect that the two rotating members 222 rotate relative to the second slider 15. Here, the rotating member 222 may be a sliding sleeve or a roller.

[0054] Specifically, the drive shaft 12 is provided with an annular protrusion 121, and the connecting sleeve 13 is located on the movement track of the annular protrusion 121. When the drive shaft 12 rotates radially, an axial driving force is generated, and the annular protrusion 121 drives the connecting sleeve 13 to move axially.

[0055] Specifically, a driving part 122 is provided at one end of the driving shaft 12 away from the limiting plate 11. The setting of the driving part 122 makes the rotation drive more convenient. Here, the driving part 122 can be a regular hexagonal prism structure or a regular quadrangular prism structure. The driving part 122 can form a driving effect manually or electrically, thereby achieving a clamping effect of the sleeve and improving the accuracy of the winding of the amorphous ribbon.

[0056] In this embodiment, the drive shaft 12 rotates radially and forms an axial movement force through the screw transmission structure, so that the adjustment is more precise.

[0057] Obviously, the above embodiments are merely examples for the purpose of clear explanation, and are not intended to limit the implementation methods. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived therefrom are still within the scope of protection of the invention of the utility model.
