Description

Technical Field

[0001] The utility model relates to a jig for adjusting the spacing between springs of a moving iron unit. Background Art

[0002] True wireless earphones are increasingly being used in our daily lives, effectively eliminating the limitations and inconveniences of wired headphones. The industry is rapidly expanding. A balanced armature driver (BAL) is an electroacoustic transducer used in earphones and hearing aids, converting electrical signals into sound signals. However, the BAL driver's extremely small size makes assembly extremely difficult, necessitating automated assembly and testing.

[0003] The reed is a core component of the moving-arm unit, just like the motor assembly. Together with the motor assembly, it completes the electromagnetic conversion process of the moving-arm unit. The reed first receives magnetic energy converted by the motor assembly through electromagnetic induction. Then, due to the periodic changes in this magnetic energy caused by the alternating current, the reed also periodically changes its north and south poles. As a result, in a constant magnetic field, the reed undergoes reciprocating mechanical motion, driving the diaphragm to vibrate and produce sound. The spacing between the current reeds does not meet the specified requirements before machining. Furthermore, due to their small size, the reeds are typically machined individually by hand using a jig, which is inefficient.

[0004] In view of the above-mentioned defects, the designers have actively carried out research and innovation in order to create a new structure of the jig for adjusting the spacing of the springs of the moving iron unit, so as to make it more valuable for industrial use. Utility Model Content

The movable rod is passed through the center of the right movable clamping block, and one end of the movable rod passes through the left fixed clamping block and is connected with the clamping member. The left fixed clamping block is provided with a left spring groove, and the right movable clamping block is provided with a right spring groove opposite to the left spring groove, and a return spring is connected between the left and right spring grooves, and a plurality of positioning grooves for placing products are provided on the convex block of the left fixed clamping block of the convex structure. The fixed base is connected with a support plate, the top end of the support plate is connected with a connecting plate, and the connecting plate is connected with a driving device, and the driving shaft of the driving device passes through the connecting plate and is connected to the spacing adjustment plate, and the spacing adjustment plate is located at the central axis of the positioning groove.

[0008] Preferably, in the jig for adjusting the spacing between springs of a moving iron unit, the clamping member is a clamping wheel with a handle.

[0009] Preferably, the jig for adjusting the spacing between springs of a moving iron unit is: the driving device is a cylinder.

[0010] Preferably, in the jig for adjusting the spacing between springs of a moving iron unit, the spacing adjustment plate is connected to an external heating device via a wire.

[0011] Preferably, in the jig for adjusting the spacing between springs of a moving iron unit, a guide rod is passed through the connecting plate, and the guide rod passes through the connecting plate and is connected to the spacing adjustment plate.

[0021] Example

[0022] like Figure 1 、 Figure 2 and Figure 3 As shown, a jig for adjusting the spacing of the springs of a moving iron unit comprises a fixed base 1, the fixed base 1 is connected to a left fixed clamping block 2, the left fixed clamping block 2 is a convex structure, the fixed base 1 is connected to a right movable clamping block 3, the right movable clamping block 3 is a concave structure and matches the convex structure of the left fixed clamping block 2, a movable rod 4 is passed through the center of the right movable clamping block 3, and one end of the movable rod 4 passes through the left fixed clamping block 2 and is connected to the clamping member 5, a left spring groove 6 is provided on the left fixed clamping block 2, and a right movable clamping block 3 is provided on the left fixed clamping block 2. A right spring groove 7 is provided opposite to the left spring groove 6, and a return spring 8 is connected between the left spring groove 6 and the right spring groove 7. A plurality of positioning grooves for placing products are provided on the convex block of the left fixed clamp 2 of the convex structure, and a support plate 9 is connected to the fixed base 1, and a connecting plate 10 is connected to the top of the support plate 9, and a driving device 11 is connected to the connecting plate 10. The driving shaft of the driving device 11 passes through the connecting plate 10 and is connected to the spacing adjustment plate 12, and the spacing adjustment plate 12 is located at the central axis of the positioning groove.

[0023] The clamping member 5 in the present invention is a clamping wheel with a handle, which can achieve rapid clamping.

[0024] The driving device 11 in the present invention is a cylinder.

[0025] The spacing adjustment plate 12 in the present invention is connected to an external heating device via a wire.

[0026] The connecting plate 10 of the present invention is connected with a guide rod 13, and the guide rod 13 passes through the connecting plate and is connected to the spacing adjustment plate 12, thereby improving its stability.

[0027] The working principle of this utility model is as follows:

[0028] During the specific operation, after placing product A (reed) in the positioning groove, the spacing adjustment plate is driven downward by the cylinder to fix the product in the positioning groove. Then, the right movable clamp is closed to the left fixed clamp by the clamping wheel, thereby reducing the distance between the reeds to the thickness of the spacing adjustment plate. After completion, the processed reeds are taken out.

[0029] At the same time, the spacing adjustment plate and the adjusted spacing are removed together. The spacing adjustment plate is connected to the auxiliary connecting plate in a plug-in manner, which is easy to operate and can be quickly replaced with the corresponding thickness as needed to meet the spacing requirements of different reeds.
