DETAILED DESCRIPTION

[0022] The technical solution of this utility model will be further described below with reference to the accompanying drawings and embodiments.

[0023] like Figures 1-6 As shown in the figure, this utility model embodiment proposes a speaker cover stamping assembly fixture, including:

[0024] Assembly table 1 includes a support platform and four support legs. The support legs are fixed to the bottom of the support platform. Tooling 4 and support column 2 are installed on the support platform. Two tooling 4 are provided on the assembly table 1. Tooling 4 is used to place the assembled speaker mask. Corresponding protrusions or marks can be set on the tooling 4. The tooling 4 can be set according to the actual situation. That is to say, when the assembled and unpressed mask is placed in the tooling 4 and is opposite to the protrusion or mark, the mask is in place so that it can be pressed in later.

[0025] The pressing assembly includes an electric push rod 5 mounted on an assembly table 1 and capable of reciprocating between two tooling fixtures 4. Four support columns 2 are fixed on the assembly table 1, and mounting plates 3 are fixed to the upper ends of the four support columns 2. An electric slide rail 8 is mounted on the bottom of the mounting plate 3, and an electric slider 9 is slidably connected to the electric slide rail 8. An assembly plate 10 is mounted on the electric slider 9, and the electric push rod 5 is mounted on the assembly plate 10. In order to ensure the stable up and down movement of the circular plate 6, a telescopic rod can be fixed on the assembly plate 10 and the circular plate 6, thus ensuring the stable up and down movement of the circular plate 6. The electric slider 9 reciprocates on the electric slide rail 8, driving the assembly plate 10 to reciprocate, which in turn drives the electric push rod 5 to reciprocate.

[0026] A drive rod 7 is fixed to the output end of the electric push rod 5. A circular plate 6 is fitted around the drive rod 7 and fixedly connected to it. A pressure ring 11 is provided below the circular plate 6. A compression spring 12 is fixed between the pressure ring 11 and the circular plate 6. A fixing cone 14 that mates with the speaker grille is fixed to the bottom of the pressure ring 11. The fixing cone 14 is made of stainless steel. For example... Figure 4 , 6 The fixed cone 14 shown is positioned opposite the screw hole on the speaker cover. Since the fixed cone 14 is wrapped with a rubber membrane, it is protected from scratches when it is aligned with the screw hole.

[0027] When the speaker cover is placed in the fixture 4, the electric push rod 5 drives the drive rod 7, the circular plate 6, the compression spring 12, the pressure ring 11, and the fixing cone 14 to move downward. The fixing cone 14 moves downward and extends into the screw hole. As the output end of the electric push rod 5 moves downward, the fixing cone 14 cannot move downward because it is against the speaker cover. This feedback indicates that the pressure ring 11 cannot move downward. Therefore, there is a relative movement between the circular plate 6 and the pressure ring 11. The compression spring 12 is compressed, which applies pressure to the pressure ring 11 and the fixing cone 14. Thus, the assembled speaker cover can be pressed and positioned without the need for additional clamps.

[0028] The slidingly arranged rectangular frame 13 is provided through the compression ring 11, and the rectangular slot 16 is provided through the compression ring 11. The rectangular frame 13 penetrates the rectangular slot 16 and is connected with the rectangular slot 16 in a sliding manner. In this way, the rectangular frame 13 plays a guiding role for the compression ring 11, so that the compression ring 11 moves stably and avoids rotating.

[0029] The rectangular frame 13 is fixedly connected with the bottom of the circular plate 6. The resettable compression block 15 is connected with the rectangular frame 13 in a sliding manner. The extrusion spring 18 is fixedly connected with the bottom of the circular plate 6. The other end of the extrusion spring 18 is fixedly connected with the compression block 15. The arc surface 17 is arranged on the compression block 15. The arc surface 17 cooperates with the rectangular frame 13 to complete the compression of the speaker grille. The compression is explained in detail as follows: when the speaker grille is fixed, the circular plate 6 moves downward with the rectangular frame 13. The compression block 15 is opposite to the bent ear. Since the arc surface 17 is arranged, when the arc surface 17 abuts against the bent ear, the bent ear is bent. It should be noted that at this time, the extrusion spring 18 is extruded and compressed. Correspondingly, the compression block 15 slides into the rectangular frame 13. Therefore, the bent ear can be gradually bent. Finally, the compression block 15 is completely accommodated in the rectangular frame 13. The rectangular frame 13 abuts against the bent ear. Finally, the rectangular frame 13 flattens the bent ear, thereby realizing the compression of the speaker grille.

[0030] It should be noted that the width of the rectangular frame 13 is less than the width of the bent ear, so as to avoid that the bent ear is clamped in the rectangular frame 13.

[0031] At this time, the speaker grille in one of the fixtures 4 is compressed. The worker can place the speaker grille in the other fixture 4 for preparation. After the compression is completed, the electric push rod 5 is reset, and then moves to the top of the fixture 4 which is prepared. Then, the compression is performed. The worker can take out the other compressed speaker grille, and then reassembles and places it.

[0032] In this way, the worker is away from the electric push rod 5 during the compression process, so that the work is safer and the safety hidden danger during the compression is eliminated.

[0033] In summary, through the cooperation of the electric push rod, the compression ring, the fixed cone and the compression block, the automatic compression and positioning of the speaker grille are realized. Manual operation and additional clamps are not required, the assembly efficiency and the yield are improved. In addition, the worker is away from the compression area during the compression process, so that the work safety is ensured. In addition, the fixture is reasonably designed, and the work can be recycled, thereby further improving the assembly efficiency.

[0034] Finally, it is explained that the above embodiments are only used to illustrate the technical solutions of the present application and are not limited. Although the present application has been described in detail with reference to the preferred embodiments, it should be understood by those skilled in the art that the technical solutions of the present application can be modified or replaced by equivalents without departing from the purpose and scope of the present application. The technical solutions of the present application should be covered in the scope of the claims of the present application.
