A connecting block is welded to the outside of the base, and the top of the connecting block is welded to one end of the bottom of a slide rod. A spring is fitted onto the outside of the slide rod, and one end of the slide rod is welded to a top plate. Cylinders are embedded inside both ends of the top of the top plate. Two cylinders are provided, and the telescopic ends of the bottom of the two cylinders are connected to lifting plates. Two lifting plates are provided, and slots are opened at both ends of the two lifting plates. The inner walls of the slots at both ends of the lifting plates slide in contact with the outer wall of the slide rod. A wire drawing abrasive belt is provided between the two lifting plates. The two ends of the wire drawing abrasive belt are connected to the output end of a drive motor through shafts. The drive motor is installed on one side of the lifting plate by screws. A lifting block is provided inside the base. One end of the lifting block is connected to a slider through a first threaded rod, and the slider is connected to the base through a second threaded rod. A workpiece is placed on the surface of the base.

[0005] Preferably, the outer surface of the base has a groove, the outer groove of the base slides in contact with the lifting block, one end of the lifting block is threadedly connected to the first threaded rod, the bottom end of the first threaded rod is rotatably connected to the top end of the slider, and thus the rotation of the first threaded rod can drive the lifting block to move up and down, thereby limiting and fixing the processed parts of different thicknesses.

[0006] Preferably, the slider is internally threaded to the external thread of the second threaded rod, one end of the second threaded rod is rotatably connected to the base, and the other end of the second threaded rod is welded to the knob. By rotating the second threaded rod, the second threaded rod can drive the slider to move, thereby enabling the device to fix speaker grilles of different sizes.

[0007] Preferably, the top of the lifting block protrudes from the surface of the base, and one side of the lifting block is in contact with the workpiece, so that one end of the top of the lifting block can fix and limit the workpiece through the protruding area.

[0008] Preferably, the two sides of the slider are in sliding contact with the inner wall of the outer groove of the base, and there is a gap between the surface of one end of the slider and the base, so that the slider has a reserved sliding space.

[0009] This utility model provides a fully automatic wire drawing machine for producing speaker grilles. It has the following beneficial effects:

[0010] (1) The fully automatic wire drawing machine for producing speaker mesh, when in use, drives the wire drawing sand belt to rotate by the drive motor, and then, under the push of the cylinder, the high-speed rotating wire drawing sand belt can move downward to grind the surface of the workpiece. When it is necessary to process a thinner speaker mesh, the first threaded rod is rotated so that the first threaded rod can drive the lifting block to move upward, so that the top of the lifting block slightly protrudes from the top surface of the base, so that the speaker mesh can be placed on the top of the base, and the outer side of the speaker mesh can be limited and fixed by the lifting block, which makes it easier for the device to fix thinner workpieces.

[0011] (2) The fully automatic wire drawing machine for producing speaker mesh can rotate the second threaded rod, thereby enabling the second threaded rod to drive the slider to move. While the slider moves, it can drive the lifting block to move horizontally through the first threaded rod, thereby adjusting the distance between each lifting block, so that the device can fix speaker mesh of different sizes.

[0012] This solves the problem that existing devices have difficulty fixing thinner workpieces. Attached Figure Description

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Example 1:

[0020] Please see Figure 1-4 This utility model provides a technical solution: a fully automatic wire drawing machine for producing speaker grilles, including a base 1, a slider 11, and a lifting block 12. A connecting block 7 is welded to the outside of the base 1. The top of the connecting block 7 is welded to one end of the bottom of the slide rod 2. A spring 6 is fitted on the outside of the slide rod 2, and one end of the slide rod 2 is welded to the top plate 10. Two cylinders 4 are embedded in the top two ends of the top plate 10. The bottom extension ends of the two cylinders 4 are connected to the lifting plate 5. Two lifting plates 5 are provided, and slots are opened at both ends of the two lifting plates 5. The inner walls of the slots at both ends of the lifting plates 5 slide in contact with the outer wall of the slide rod 2. A wire drawing sanding belt 3 is provided between the two lifting plates 5. The two ends of the wire drawing sanding belt 3 are connected to the output end of the drive motor 9 through shafts. The drive motor 9 is installed on one side of the lifting plate 5 by screws. A lifting block 12 is provided inside the base 1. One end of the lifting block 12 is connected to the slider 11 through a first threaded rod 13. The slider 11 is connected to the first threaded rod 13 through the first threaded rod 12. The threaded rod 14 is connected to the base 1. A workpiece 8 is placed on the surface of the base 1. A groove is provided on the outer surface of the base 1. The groove on the outer surface of the base 1 slides in contact with the lifting block 12. One end of the lifting block 12 is threadedly connected to the first threaded rod 13. The bottom end of the first threaded rod 13 is rotatably connected to the top end of the slider 11. When the device is in use, the drive motor 9 drives the wire drawing sanding belt 3 to rotate. Then, under the push of the cylinder 4, the high-speed rotating wire drawing sanding belt 3 can move downward to grind the surface of the workpiece 8. When it is necessary to process a thinner speaker mesh, by rotating the first threaded rod 13, the first threaded rod 13 can drive the lifting block 12 to move upward, so that the top of the lifting block 12 slightly protrudes from the top surface of the base 1, so that the speaker mesh can be placed on the top of the base 1. The outer side of the speaker mesh can be limited and fixed by the lifting block 12, which makes it easier for the device to fix thinner workpieces.

[0021] Example 2:

[0022] This utility model embodiment provides a technical solution: a fully automatic wire drawing machine for producing speaker grilles. The slider 11 is internally connected to the external thread of the second threaded rod 14. One end of the second threaded rod 14 is rotatably connected to the base 1, and the other end of the second threaded rod 14 is welded to the knob 15. The top of the lifting block 12 protrudes from the surface of the base 1, and one side of the lifting block 12 is in contact with the workpiece 8. The two sides of the slider 11 are in sliding contact with the inner wall of the outer groove of the base 1. There is a gap between one end of the slider 11 and the base 1. By rotating the second threaded rod 14, the second threaded rod 14 can drive the slider 11 to move. While the slider 11 is moving, the first threaded rod 13 can drive the lifting block 12 to move horizontally, thereby adjusting the distance between each lifting block 12, so that the device can fix speaker grilles of different sizes.

[0023] Working Principle: During operation, the drive motor 9 rotates the wire-drawing abrasive belt 3, which is then pushed downwards by the cylinder 4 to polish the surface of the workpiece 8. When processing thinner speaker grilles, the first threaded rod 13 is rotated, causing it to move the lifting block 12 upwards, so that the top of the lifting block 12 is slightly higher than the top of the base 1. This allows the speaker grille to be placed on top of the base 1 and fixed on the outside by the lifting block 12, facilitating the device's fixation of thinner workpieces. Simultaneously, rotating the second threaded rod 14 moves the slider 11. As the slider 11 moves, it causes the lifting block 12 to move horizontally via the first threaded rod 13, thereby adjusting the spacing between the lifting blocks 12 and enabling the device to fix speaker grilles of different sizes.
