[0025] For the implementation examples, please refer to the appendix. Figure 1-4 A positioning device for stamping part processing includes a positioning table 10, an arc-shaped slide rail groove 11 on the positioning table 10, an angle adjustment mechanism 30 installed on the positioning table 10, the angle adjustment mechanism 30 includes two sliding parts that slide inside the slide rail groove 11, and two swing plates 31 installed on the top of the two sliding parts. The swing plates 31 have an L-shaped structure, and positioning bolts 32 are installed through the outer side of the end of the swing plates 31 by internal and external threads.

[0026] Clamping mechanisms 20 are installed on the top of the two swing plates 31 and the positioning platform 10 at the middle axis of the slide rail groove 11.

[0027] It should also be noted that all electrical components of this device are electrically connected to a conventional PLC controller and are powered by an external power source.

[0028] For details, please refer to the appendix. Figure 2 The angle adjustment mechanism 30 also includes a fixed shaft 33 fixedly installed at the top center of the positioning platform 10, and two connecting blocks 34 slidably sleeved on the fixed shaft 33. The two connecting blocks 34 are respectively connected to one end of the inner side of the two swing plates 31.

[0029] In this embodiment, it should be noted that, due to the limitation of the fixed axis 33, both swing plates 31 can adjust their angles around the fixed axis 33, which can better adapt to the stable clamping of polygonal workpieces.

[0030] For details, please refer to the appendix. Figure 2 and attached Figure 3 An angle mark 12 is engraved around the top periphery of the positioning platform 10 in the outer area of ​​the slide rail groove 11. A slot 311 is provided on the swing plate 31 in the top area of ​​the positioning platform 10. A pointer 37 pointing to the angle mark 12 is provided on the inner wall of one side of the slot 311.

[0031] In this embodiment, it should be noted that the angle mark 12 that is parallel to the clamping mechanism 20 located on the positioning table 10 is 0°, and the other angle marks 12 are all the angles between the 0° angle mark 12 and the 0° angle mark 12. By using the angle mark 12 pointed to by the pointer 37 that passes through the slot 311 of the swing plate 31, the angle between the clamping mechanism 20 on the swing plate 31 and the clamping mechanism 20 in the fixed position can be better controlled. This makes it easier to quickly adjust the swing plate 31 to a suitable angle according to the number of sides of the polygonal workpiece, so as to facilitate fast and stable clamping and improve stamping efficiency.

[0032] For details, please refer to the appendix. Figure 1 and attached Figure 3 The slide rail 11 has a double-layer structure. The width of the top area of ​​the slide rail 11 is greater than the width of the bottom area. The sliding component consists of a connecting rod 35 located in the top area of ​​the slide rail 11 and a rolling disk 36 rotatably connected to the bottom of the connecting rod 35 and located in the bottom area of ​​the slide rail 11. The rolling disk 36 is in contact with the inner walls on both sides of the slide rail 11.

[0033] In this embodiment, it should be noted that when the swing plate 31 swings, the rolling disk 36 slides inside the slide rail groove 11, which makes the swing of the swing plate 31 more stable.

[0034] For details, please refer to the appendix. Figure 3 A rubber block 321 is provided at the end of the screw of the positioning bolt 32.

[0035] In this embodiment, it should be noted that the rubber block 321 can increase the frictional resistance. When the rubber block 321 of the positioning bolt 32 abuts against the positioning table 10, the position of the swing plate 31 can be fixed.

[0036] For details, please refer to the appendix. Figure 4 The clamping mechanism 20 includes a sliding frame 21, a ball screw 22 rotatably connected inside the sliding frame 21, a screw nut seat 23 slidably connected to the ball screw 22, a displacement plate 24 mounted on the screw nut seat 23, a drive motor 26 mounted on the outside of the sliding frame 21 and connected to the ball screw 22, and a clamping plate 25 mounted on the displacement plate 24.

[0037] In this embodiment, it should be noted that by driving the motor 26, the nut seat 23 can drive the displacement plate 24 and the clamping plate 25 to slide on the ball screw 22, adjust the distance between the multiple clamping plates 25, and thus position workpieces of different sizes, resulting in better functionality.

[0038] For details, please refer to the appendix. Figure 4 The bottom of the clamping plate 25 is provided with an insert block 27, and the top of the clamping plate 25 is provided with a slot that matches the insert block 27.

[0039] In this embodiment, it should be noted that some workpieces have curved surfaces. In this case, the clamping plate 25 can be pulled out and the clamping plate 25 with a curved inner surface can be quickly replaced to achieve more stable clamping and prevent the workpiece from shaking during the stamping process.

[0040] The specific operation method of this utility model is as follows:

[0041] First, adjust the swing plate 31 quickly according to the number of sides of the polygonal workpiece. Rotate the swing plate 31 around the fixed axis 33. The angle mark 12 pointed to by the pointer 37 through the slot 311 of the swing plate 31. After the displacement is in a suitable position, tighten the positioning bolt 32 so that it abuts against the side of the positioning table 10, thereby completing the fixation of the swing plate 31.

[0042] Then, start the drive motor 26, which will cause the screw nut 23 to slide the displacement plate 24 and the clamping plate 25 on the ball screw 22. Adjust the spacing between the multiple clamping plates 25, and finally place the workpiece on the three displacement plates 24. Finally, fine-tune the position of the clamping plate 25 to make it stably clamped, and then proceed with the subsequent stamping steps.

[0043] The present invention has been described above by way of example in conjunction with the accompanying drawings. Obviously, the specific implementation of the present invention is not limited to the above-described manner. Any non-substantial improvement made by adopting the inventive concept and technical solution of the present invention, or the direct application of the inventive concept and technical solution of the present invention to other occasions without modification, shall be within the protection scope of the present invention.
