Description

Technical Field

[0001] The utility model relates to the field of magnetic ring inductors, in particular to a magnetic ring inductor fixture. Background Art

[0002] The magnetic ring inductor includes a magnetic ring and a base. Two windings are wound on the magnetic ring with copper wire, and four pins are set on the base. In order to ensure good connection performance between the pins and the coils of the magnetic ring, it is also necessary to spirally wind the four wire ends of the two windings on the four pins respectively. Subsequently, the wire ends of the pins and the windings are welded to firmly connect the wire ends of the windings with the pins. The prior art requires the magnetic ring to be pulled before the wire ends of the magnetic ring are wound on the base, so as to straighten the wire ends of the windings of the magnetic ring. When pulling the feet, the wire ends of the magnetic ring windings will be continuously pulled. However, the magnetic ring and the base are simply stacked together, and pulling the windings will inevitably cause the magnetic ring to shake slightly. This causes relative displacement between the magnetic ring and the base, affects the alignment accuracy of the base and the magnetic ring, and reduces the assembly processing quality of the magnetic ring and the base.

[0003] Therefore, a magnetic ring inductor fixture is proposed, which can clamp and position the magnetic ring and the base during the pin pulling operation. Utility Model Content

[0005] Furthermore, an extension direction of the wire accommodating groove and an extension direction of the lower sliding groove are parallel to each other.

[0006] Preferably, the top seat is provided with a through slot, which is arranged between the wire accommodating slot and the accommodating gap, and the lower slider is detachably provided with a partition at one end close to the top seat, and the projection of the partition along the sliding direction of the lower slider divides the through slot into several channels.

[0008] Preferably, one end of the two upper sliding blocks close to the support block is provided with a step groove for accommodating the base. One end of the base can be accommodated in the step groove.

[0009] Preferably, the driving assembly further comprises a guide column, and the guide column is slidably arranged below the base up and down, and the lower ends of the first inclined wedge mechanism and the second inclined wedge mechanism are both arranged on the side of the guide column.

[0010] Preferably, a connecting channel is opened at the upper end of the fixing plate, and two ends of the connecting channel are respectively connected to the lower end of the wire accommodating groove and the upper end surface of the fixing plate, and the connecting channel is bent into an L shape or a J shape.

[0011] Preferably, the sliding direction of the guide column, the center line of the base and the center line of the top seat are collinear.

[0012] Preferably, the first inclined wedge mechanism and the second inclined wedge mechanism both include a push rod and a roller, the push rod is arranged on a guide column, the roller is rotatably arranged on a lower slider or an upper slider, the roller is arranged on the movement trajectory of the push rod, an inclined surface is provided at one end of the push rod close to the roller, and the sliding direction of the guide column is oblique to the plane where the inclined surface is located.

[0015] Preferably, the reset assembly comprises a baffle and an elastic element, the baffle is detachably arranged on the base, one end of the elastic element is arranged on the baffle, and the other end of the elastic element is arranged on the lower slider or the upper slider.

[0016] The working principle of the utility model is as follows: the inclined wedge mechanism is a mechanical mechanism that changes vertical motion into horizontal motion or tilted motion by using an inclined wedge and a slider in cooperation. The first inclined wedge mechanism and the second inclined wedge mechanism are used to convert vertical motion into horizontal motion. When the first inclined wedge mechanism and the second inclined wedge mechanism rise toward the base, the inclined surface of the top rod will push the roller to move horizontally, the lower slider will slide along the lower slide groove in a direction away from the top seat, and the upper slider will slide along the upper slide groove in a direction away from the support block.

[0017] The first and second slanted wedge mechanisms are driven to rise toward the base for the first time, the two upper sliders move away from each other, and the two lower sliders also move away from each other, placing the magnetic ring in the magnetic ring receiving groove of the support block. The first and second slanted wedge mechanisms are driven to reset, ensuring that the wire head of the magnetic ring winding is close to the end of the winding and passes through the wire receiving groove.

At this time, the two upper sliders move away from each other for the second time, and the two lower sliders also move away from each other for the second time. When the two lower sliders slide, the fixed plate of the lower slider and the wire receiving groove thereon will move linearly synchronously, and the fixed plate and the wire receiving groove thereon will move linearly to straighten the wire ends. Drive the first and second bevel wedge mechanisms to reset, and the two upper sliders move closer to each other to stably clamp the base at the upper end of the magnetic ring. At the same time, the magnetic ring is clamped between the base and the support block, and the magnetic ring and the base are clamped and positioned. Finally, the magnetic ring will be at the bottom and the base will be at the top in the fixture, and the pins of the base will be at the top, which is also convenient for subsequent foot wrapping operations.

In the process of placing the magnetic ring and the base, the wire receiving groove on the upper end of the fixing plate of the lower slider moves linearly to automatically straighten the wire head.
