Detailed implementation manners

[0026] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the scope of protection of the present utility model.

[0027] Please refer to Figure 1 - Figure 6, the present utility model provides a technical solution: a punching and positioning structure for metal processing, including a support box 1. A transmission module 2 is connected to the top of the support box 1. A cylinder 3 is connected to one side of the transmission module 2. The top rod of the cylinder 3 is connected to a splash-proof device 8. A drilling module is installed in the splash-proof device 8. The splash-proof device 8 includes a splash-proof box 802. An activity groove 801 is opened on the inner wall of the splash-proof box 802. A splash-proof cylinder 804 is slidably connected in the activity groove 801. Two fixing grooves 806 are opened at the top of the splash-proof cylinder 804. A fixing rod 805 is slidably connected to the inner wall of the fixing groove 806. A first spring 807 is sleeved on the outer wall of the fixing rod 805. The top of the splash-proof box 802 is connected to the top rod of the cylinder 3. One side of the drilling module is connected to the top of the inner wall of the splash-proof box 802. Both ends of the first spring 807 are respectively connected to the top of the splash-proof cylinder 804 and one side of the inner wall of the activity groove 801. The other end of the fixing rod 805 is connected to one side of the inner wall of the activity groove 801. Two limiting grooves are opened on the inner wall of the activity groove 801. A limiting block 803 is slidably connected in the limiting groove. One side of the limiting block 803 is connected to the outer wall of the splash-proof cylinder 804.

[0028] In the specific implementation manner, by setting the first spring 807, due to the elasticity of the first spring 807, the first spring 807 drives the bottom of the splash-proof cylinder 804 to closely fit the surface of the workpiece to be processed, avoiding the up and down movement of the splash-proof cylinder 804 due to machine vibration, thereby reducing the splash-proof effect. By setting the fixing rod 805, through the support of the fixing rod 805, the first spring 807 is prevented from bending when compressed, and thus the resilience of the first spring 807 is ensured.

[0029] A through groove 10 is opened at the top of the support box 1. A motor 5 is fixedly installed on one side of the support box 1. The output shaft of the motor 5 extends into the through groove 10 and is connected to a threaded rod 7. The other end of the threaded rod 7 is rotatably connected to one side of the inner wall of the through groove 10. A threaded seat 6 is threadedly connected to the outer wall of the threaded rod 7. A supporting plate 4 is connected to the top of the threaded seat 6. A clamping device 9 is connected to the top of the supporting plate 4. The clamping device 9 includes two fixing blocks 902. An electric push rod 901 is fixedly installed on one side of the fixing block 902. The top rod of the electric push rod 901 penetrates through the fixing block 902 and is connected to a moving block 903. A plurality of built-in grooves 907 are opened on one side of the moving block 903. A contact rod 904 is slidably connected to the inner wall of the built-in groove 907. A supporting groove is opened at one end of the contact rod 904. A supporting rod 909 is slidably connected in the supporting groove. A second spring 908 is sleeved on the outer wall of the supporting rod 909. Two sliding grooves 906 are opened on the inner wall of the built-in groove 907. A sliding rod 905 is slidably connected in the sliding groove 906. One end of the sliding rod 905 is connected to the outer wall of the contact rod 904. The other end of the supporting rod 909 is connected to one side of the inner wall of the built-in groove 907. Both ends of the second spring 908 are respectively connected to one end of the contact rod 904 and one side of the inner wall of the built-in groove 907. The bottom of the fixing block 902 is connected to the top of the supporting plate 4. A rubber pad is provided at one end of the contact rod 904.

[0030] Specific implementation manner: By setting the support rod 909, the support rod 909 supports the second spring 908, so that when the second spring 908 is compressed, the second spring 908 is prevented from shaking left and right, thereby ensuring the resilience effect of the second spring 908, and thus ensuring the support property of the second spring 908. By setting a rubber pad at one end of the contact rod 904, through the buffering of the rubber pad, it is avoided that the contact rod 904 comes into hard contact with the workpiece to be processed, which may damage the surface of the workpiece to be processed and affect its use. Moreover, the rubber pad can also provide better friction, further ensuring the stability of the workpiece to be processed during processing.

[0031] Working principle: When in use, place the workpiece to be processed on the top of the supporting plate 4. Drive the moving block 903 to move through the ejector rod of the electric push rod 901. Then, the moving block 903 drives the contact rod 904 to move through the built-in groove 907, so that the contact rod 904 contacts the workpiece to be processed. Then, through the contraction of the second spring 908, multiple contact rods 904 can contact different horizontal plane positions of the workpiece to be processed, thereby effectively fixing some irregular workpieces to be processed and improving the practicability of the device. When drilling, drive the splash-proof box 802 to move downward through the air cylinder 3, and then drive the splash-proof cylinder 804 to move downward. When the bottom of the splash-proof cylinder 804 contacts the top of the workpiece to be processed, the splash-proof cylinder 804 and the splash-proof box 802 shield the drilling area to prevent waste chips from flying around and causing inconvenience in subsequent cleaning. Finally, the splash-proof cylinder 804 slides in the movable groove 801, so that the drilling module in the splash-proof box 802 drills the workpiece to be processed.
