The positioning tooling further includes a turntable 2 rotatably arranged above the operating table 1, a power member 3 for driving the turntable 2 to rotate intermittently, a positioning table 4 detachably arranged above the turntable 2, a positioning member 5 for positioning the sheet metal part on the positioning table 4, and a pressing member 6 for pressing the sheet metal part against the positioning member 5. During stamping, the sheet metal part can be fixed on the positioning table 4 through the pressing member 6 and the positioning member 5, and then the power member 3 drives the turntable 2 to rotate, driving the sheet metal part to rotate under the stamping device 101, so that the sheet metal part can be stamped. Then, the turntable 2 rotates again to drive the sheet metal part back to the loading position, and thus the material can be taken and loaded, without the need to operate under the stamping device 101, reducing potential safety hazards.

[0037] Referring to Figure 1 and Figure 2 , further, a plurality of positioning tables 4 can be arranged along the circumferential direction of the turntable 2. In this embodiment, four are provided. Thus, when one positioning table 4 drives the sheet metal part for stamping, the other positioning tables 4 can take and load materials, reducing the waiting time for the equipment to stamp and improving the stamping efficiency.

[0038] Referring to Figure 1 and Figure 2, in this embodiment, the operating table 1 includes a rectangular tabletop and support legs for supporting the tabletop. The cross-section of the turntable 2 can be circular. A central column 21 is coaxially fixed to the lower surface of the rotating disk. The central column 21 extends downward through the tabletop portion of the operating table 1, and the outer sidewall of the central column 21 is rotatably connected to the operating table 1 by means of a bearing or the like. The power member 3 includes a worm gear 31, a worm 32, and a motor 33. Among them, the worm gear 31 is coaxially fixed to the outer sidewall of the lower end of the central column 21. A plurality of supports are fixed to the lower surface of the rectangular tabletop of the operating table 1. The two ends of the worm 32 are rotatably connected between the two supports. The motor 33 is preferably a stepping motor 33. The motor 33 is fixed to the operating table 1 by means of bolts or the like. The rotating shaft of the motor 33 is connected to one end of the worm 32. The worm 32 meshes with the worm gear 31. Thus, starting the motor 33 can drive the worm 32 to rotate, drive the worm gear 31 and the central column 21 to rotate, and finally drive the turntable 2 to rotate.

[0039] Refer to Figure 1 and Figure 2 , in this embodiment, in order to improve the stability of the turntable 2 during rotation, a support ring 11 is fixed to the upper panel of the support table. A ring groove for inserting and rotating the support ring 11 is formed on the lower surface of the turntable 2. The central column 21 coaxially passes through the support ring 11. Thus, the support ring 11 can support the turntable 2.

[0040] Refer to Figure 3 and Figure 4 , in this embodiment, the cross-section of the positioning table 4 is rectangular. A relief groove 41 for stamping is formed on the upper surface of the positioning table 4. The relief groove 41 extends along the length direction of the positioning table 4.

Thus, when the sheet metal part is placed on the positioning table 4, one side of the sheet metal part abuts against the sidewalls of the two positioning posts 51, and the sheet metal part can be preliminarily positioned. Further, a chamfer is formed at the upper end of the positioning post 51, so that the upper end of the positioning post 51 is frustum-shaped. When the middle position of the sheet metal part is pressed downward and bent, and both sides are upturned, the possibility of friction between the sheet metal part and the upper end of the positioning post 51 can be reduced.

[0041] Refer to Figure 3 and Figure 4 , in this embodiment, a threaded post 52 is integrally formed at the lower end of the positioning post 51. A first threaded hole 42 for threaded connection of the threaded post 52 is formed on the upper surface of the positioning table 4. A plurality of first threaded holes 42 are spaced along the length direction of the relief groove 41. Thus, the position of the positioning post 51 can be adjusted to adapt to sheet metal parts of different widths.

[0042] Refer to Figure 3 and Figure 4, in this embodiment, the positioning post 51 is arranged at one end of the relief groove 41 along the length direction of the relief groove 41, and the pressing member 6 is arranged at the other end of the accommodating groove, so that the sheet metal part can be pressed against the side wall of the positioning post 51. Specifically, the pressing member 6 includes a positioning block 61, a pressing rod 62, a stop block 63, a spring 64 and a pressing block 65.

[0043] During use, first drive the stop block 63 to slide away from the positioning post 51 through the stop block 63, then place the sheet metal part, release the stop block 63, and the pressing block 65 moves towards the sheet metal part under the elastic force of the spring 64 to press the sheet metal part against the side wall of the positioning post 51; or it is also possible to first press the side wall of the sheet metal part against the side walls of the two pressing blocks 65 and make the pressing blocks 65 move away from the positioning post 51, and after placing the sheet metal part between the pressing blocks 65 and the positioning post 51, release the sheet metal part, and the sheet metal part can be pressed between the positioning post 51 and the pressing block 65 under the action of the spring 64.

[0044] Refer to Figure 3 and Figure 4 , in this embodiment, the positioning block 61 is detachably arranged on the positioning table 4. Specifically, a positioning bolt 7 is arranged on the positioning block 61, and a second threaded hole 43 for threaded connection of the positioning bolt 7 is opened on the upper surface of the positioning table 4. The positioning bolt 7 can pass through the positioning block 61 and be threadedly connected with the second threaded hole 43 to fix the positioning block 61 on the positioning table 4; optionally, two positioning bolts 7 are arranged on the positioning block 61 and are respectively located on both sides of the pressing rod 62. Further, the second threaded holes 43 can be arranged at intervals along the length direction of the relief groove 41 on the positioning table 4, so as to be able to adjust the position of the positioning block 61 to adapt to sheet metal parts of different widths.

[0045] Refer to Figure 3 and Figure 4 , in this embodiment, fixing bolts 44 are arranged on the positioning table 4, and third threaded holes for threaded connection of the fixing bolts 44 are opened on the upper surface of the turntable 2.
