Changes or adjustments in their relative relationships shall be regarded as the scope of application of the present utility model without substantially changing the technical content.

[0023] Reference Figure 1-Figure 3 A clamping mechanism for processing and producing aluminum alloy discs includes a lower template 1, a positioning groove 20 is opened on the upper surface of the lower template 1, and a plurality of punching holes 2 are opened on the wall of the positioning groove 20. Extensions 14 are fixedly installed at both ends of the lower template 1, and first threaded rods 3 with opposite thread directions at both ends are horizontally rotatably installed in the two extensions 14. U-shaped sliders 4 are symmetrically threadedly sleeved on the first threaded rods 3. The two sliders 4 are restricted from rotating by a first limiting component. The first limiting component includes a profiling block 8 and two hinged rods 9. A slide groove 10 is horizontally opened on the bottom wall of the extension 14. A slide rod 11 is horizontally fixedly installed in the slide groove 10. A slide rod 11 is slidably sleeved on the slide rod 11. Sliding block 12, the upper surface of the sliding block 12 is fixedly connected to the lower surface of the I-shaped block 8 through a connecting rod, the opening of the sliding block 4 and the left and right openings of the I-shaped block 8 are vertically fixedly installed with mounting rods, the two ends of the two hinged rods 9 are respectively located in the multiple openings, and are respectively rotatably sleeved on the multiple mounting rods, and the surface of the lower template 1 is symmetrically rotatably installed with rotating rods, one end of the two rotating rods is respectively fixedly connected to one end of the two first threaded rods 3, and the end of the rotating rod away from the first threaded rod 3 is fixedly installed with an adjusting wheel, and the first threaded rod 3 can be controlled to rotate by rotating the adjusting wheel outside the lower template 1, without the need to put the hand into the extension part 14 to control the rotation of the first threaded rod 3, which is convenient and quick;

[0024] A second threaded rod 5 is vertically rotatably mounted on the upper surface of the slider 4, a slide plate 6 is threadedly sleeved on the second threaded rod 5, a positioning plate 7 is fixedly mounted on the lower surface of the slide plate 6 through a connecting rod, and the slide plate 6 is restricted in rotation by a second restriction component, the second restriction component includes a mounting plate 15 fixedly mounted on the upper surface of the extension portion 14 and a restriction rod 16 fixedly mounted on the surface of the slide plate 6, a restriction opening 17 is vertically opened on the surface of the mounting plate 15, and the restriction rod 16 is vertically slidably disposed in the restriction opening 17;

[0025] First, lay the coil to be positioned in the positioning groove 20, and then rotate the first threaded rod 3. At this time, the two sliders 4 threadedly sleeved on the first threaded rod 3 will move laterally relative to each other under the restriction of the two hinged rods 9 and the I-shaped block 8. When the two sliders 4 are close to each other, the I-shaped block 8 will move away from the two sliders 4. When the two sliders 4 are away from each other, the I-shaped block 8 will approach the two sliders 4 until the two positioning plates 7 are both located above the coil. At this time, stop rotating the first threaded rod 3, and then rotate the two second threaded rods 5 respectively. At this time, the slide plate 6 threadedly sleeved on the second threaded rod 5 will move vertically with the positioning plate 7 under the restriction of the restriction rod 16 and the restriction mouth 17, until the positioning plate 7 moves to tightly abut against the coil, the positioning of the coil can be completed, and the size of the positionable coil is no longer constant, thereby improving practicality.

[0027] The arc groove 13 and the ball can support the sliding block 12 and limit the rotation of the sliding block 12. At the same time, the ball can also reduce the friction between the contact surface of the sliding block 12 and the sliding groove 10 to avoid jamming of the sliding block 12 during movement.

[0028] A transmission assembly is provided above the I-shaped block 8, and the transmission assembly is used to control the two second threaded rods 5 located above the same first threaded rod 3 to rotate together. The transmission assembly includes three guide wheels 18 and elastic friction ropes 21. A rotating shaft 19 is vertically rotatably installed on the upper surface of the I-shaped block 8.

[0030] In the utility model, the coil to be positioned is firstly laid flat in the positioning groove 20, and then the first threaded rod 3 is rotated. At this time, the two sliders 4 threadedly sleeved on the first threaded rod 3 will move laterally relative to each other under the limiting action of the first limiting component, until the two positioning plates 7 are both located above the coil. At this time, the rotation of the first threaded rod 3 is stopped, and then the two second threaded rods 5 are rotated respectively. At this time, the slide plate 6 threadedly sleeved on the second threaded rod 5 will move vertically with the positioning plate 7 under the limiting action of the second limiting component, until the positioning plate 7 moves to tightly abut against the coil, the positioning of the coil can be completed, the size of the positionable coil is no longer constant, and the practicality is improved.
