DETAILED DESCRIPTION

[0020] The following is combined with Figure 1-3 This application is described in further detail.

[0021] The present application embodiment discloses a cutting device for rare earth aluminum alloy. Figure 1-3 A cutting device for rare earth aluminum alloy comprises a bottom plate 1, two rectangular blocks 11 are symmetrically arranged on the upper end of the bottom plate 1, and the two rectangular blocks 11 are provided with a slide groove 2, and the opposite surfaces of the two rectangular blocks 11 are provided with a limit groove 15, and the two limit grooves 15 are provided with a connecting plate 14, and the opposite surfaces of the two connecting plates 14 are fixedly connected with a fixing plate 10, and the bottom plate 1 is provided with a fixing mechanism for the rare earth aluminum alloy cutting device;

[0022] The fixing mechanism includes a limit block 16 fixedly connected to the back sides of the two connecting plates 14 . The two limit blocks 16 are both provided with a wedge-shaped groove 17 . The two slide grooves 2 are both provided with a wedge-shaped block 18 matched with the wedge-shaped groove 17 .

[0023] The appropriate fixing plate 10 can be replaced according to the actual shape of the rare earth aluminum alloy. When it is necessary to connect the limit block 16 with the rectangular block 11, the connecting plate 14 is inserted into the limit groove 15. During this process, when the limit block 16 passes through the wedge block 18, it will push the wedge block 18 upward and stretch the connecting spring 13. When the wedge block 18 reaches the wedge groove 17, it will be elastically acted upon by the connecting spring 13 and the wedge block 18 will be stuck into the wedge groove 17 to complete the installation. The suitable fixing plate 10 can be quickly replaced to better fix the rare earth aluminum alloy workpiece and improve the processing efficiency.

[0024] Reference Figure 2-3The upper ends of the two wedge-shaped blocks 18 are fixedly connected with pull rods 19, and the upper ends of the two pull rods 19 extend to the upper ends of the corresponding rectangular blocks 11 and are fixedly connected with pull plates 12. The lower ends of the two pull plates 12 are elastically connected to the upper ends of the corresponding rectangular blocks 11 through two connecting springs 13. The upper ends of the two pull plates 12 are fixedly connected with pull rings. A sliding cavity 6 is opened in the bottom plate 1, and a two-way threaded rod 9 is rotatably connected between the inner walls on the left and right sides of the sliding cavity 6. The two-way threaded rod 9 is threadedly connected to the lower ends of the two rectangular blocks 11. The two rectangular blocks 11 are slidably connected to the front and rear inner walls of the sliding cavity 6. A motor 5 is installed on the left side of the bottom plate 1, and the end of the output shaft of the motor 5 extends into the sliding cavity 6 and is fixedly connected to one end of the two-way threaded rod 9. The model of the motor 5 can be selected as YE2-6344-37KW, and a plurality of bottom columns are symmetrically fixedly connected to the lower end of the bottom plate 1.

[0025] The rare earth aluminum alloy to be cut is placed on the upper end of the base plate 1, between the two fixed plates 10, and the motor 5 is started to rotate the bidirectional threaded rod 9, thereby causing the two rectangular blocks 11 threadedly connected thereto to drive the corresponding fixed plates 10 to move relative to each other, thereby fixing the two ends of the rare earth aluminum alloy. This allows the device to adapt to more rare earth aluminum alloy workpieces of different shapes and sizes.

[0026] Reference Figure 1 The upper end of the bottom plate 1 is fixedly connected to two vertical rods 3, and the upper ends of the two vertical rods 3 are commonly fixedly connected to a top plate 4. An electric telescopic rod 7 is installed at the lower end of the top plate 4. A cutting tool 8 is provided at the telescopic end of the electric telescopic rod 7. The cutting tool 8 is made of cemented carbide material and has excellent wear resistance and impact resistance.

[0027] The implementation principle of the cutting device for rare earth aluminum alloy in the embodiment of the present application is as follows: when in use, the appropriate fixing plate 10 can be replaced according to the actual shape of the rare earth aluminum alloy. When the limit block 16 needs to be connected to the rectangular block 11, the connecting plate 14 is inserted into the limit groove 15. In this process, when the limit block 16 passes through the wedge block 18, it will push the wedge block 18 to move up and stretch the connecting spring 13. When the wedge block 18 reaches the wedge groove 17, it is elastically acted upon by the connecting spring 13, and the wedge block 18 is stuck in the wedge groove 17. The installation is completed, and the adapted fixing plate 10 can be quickly replaced, thereby better fixing the rare earth aluminum alloy workpiece and improving the processing efficiency.

[0028] Then, the rare earth aluminum alloy to be cut is placed on the upper end of the bottom plate 1, between the two fixing plates 10, and the motor 5 is started to rotate the bidirectional threaded rod 9, so that the two rectangular blocks 11 threadedly connected thereto drive the corresponding fixing plates 10 to move relatively, and the two ends of the rare earth aluminum alloy are fixed, so that the device can adapt to more rare earth aluminum alloy workpieces of different shapes and sizes;

[0029] When a different fixing plate 10 needs to be replaced, the pull ring can be pulled upward. After the pull ring is pulled, the wedge block 18 can be driven upward through the pull plate 12 and the pull rod 19, so that the wedge block 18 leaves the wedge groove 17, and then the limit block 16 is separated from the rectangular block 11.
