[0036] It is worth mentioning here that by arranging gear a21 and gear b22 on the support platform, a synchronous belt 23 is sleeved on the gear a21 and gear b22, the annular guide rail 10 is arranged on the outside of the synchronous belt 23, and the conveying plate is rotatably arranged on the synchronous belt 23. The transmission is more accurate by meshing the gears with the synchronous belt 23.

[0037] like Figure 6 As shown in FIG. 7 , the fixed block 3 includes a toggle bar 31 and a slot 32. The toggle bar 31 is used to toggle the parts on the blanking frame 6 into the slot 32. The fixed component 4 includes a sliding slot 33 arranged in the fixed block 3 and a fixed plate 34 slidably arranged in the sliding slot 33. A transmission rod 35 is arranged on the side of the fixed plate 34. A sliding rod 36 for driving the transmission rod 35 to move is slidably arranged inside the fixed block 3.

[0038] It is worth mentioning here that a sliding rod 36 is slidably set inside the fixed block 3 to drive the transmission rod 35 to move. The sliding rod 36 is slidably set on the surface of the guide rail a13. During the movement, the sliding rod 36 can be driven to move by the guide rail a13, so that the fixed plate 34 moves forward to fix the parts.

[0039] As shown in Figures 3 and 4, the centering component 5 includes a fixed rod 41 arranged on the conveying plate 11, a rotating groove 42 and a linkage rod 43 rotatably arranged in the rotating groove 42 are arranged at the end of the fixed rod 41, a centering rod 44 is rotatably arranged at the bottom of the linkage rod 43, a centering block 45 is slidably arranged on the centering rod 44, a piston channel 46 and a piston 47 slidably arranged in the piston channel 46 are arranged at the end of the fixed rod 41, a piston rod 48 is arranged at the bottom of the piston 47, and the piston rod 48 is slidably arranged on the surface of the guide rail b15, and the piston channel 46 is connected to the centering block 45 through an air intake channel 49.

The piston channel 46 is connected to the centering block 44 through an air intake channel 49. The piston rod 48 is driven to move through the guide rail b15, so that the centering block 45 moves outward to center the parts, thereby preventing the parts from being offset when the holes are pulled out.

[0041] like Figure 1 As shown in FIG9 , the forming mechanism 7 includes a hole pulling machine 51 and a pushing assembly 52 arranged on the opposite side of the hole pulling machine 51. The pushing assembly 52 includes a clamping block a53 and a clamping block b54. The clamping block a53 and the clamping block b54 cooperate with each other to clamp the parts and send the parts into the hole pulling machine 51.

[0042] like Fig. 9 As shown, the shape of the clamping block a53 is configured to fit the outer wall surface of the part, and the shape of the clamping block b54 is configured to fit the inner wall surface of the part.

[0043] It is worth mentioning here that by setting the shape of clamp block a53 to fit the outer wall of the part and the shape of clamp block b54 to fit the inner wall of the part, clamp blocks a53 and b54 can fit the part better, making the clamping more firm and preventing it from falling off.

[0046] It is worth mentioning here that by setting the outer diameter of the pushing cylinder 74 to be the same as that of the part and the height of the pushing cylinder 74 coinciding with that of the part, the pushing cylinder can maintain a consistent height with the part during the pushing process, preventing deviation and damage to the device during pushing.

[0047] like Figure 6 As shown, a spring is provided between the fixing plate 34 and the sliding slot 33 .

[0048] It is worth mentioning here that by arranging a spring between the fixed plate 34 and the sliding groove 33, when the sliding rod 36 is separated from the surface of the guide rail a13, the fixed plate 34 can be reset by the spring.

[0051] The working process is as follows:

[0052] The device is started, the driving wheel 21 rotates to drive the driven wheel 22 to rotate through the synchronous belt 23, so that the conveying plate 11 moves on the annular guide rail 10. When the conveying plate 11 passes under the blanking frame 6, the shifting bar 31 causes the parts on the blanking frame 6 to fall into the card slot 32, and drives the linkage rod 43 to deviate so that it rests on the surface of the parts;

[0053] When the conveying plate 11 passes the guide rail a13, the guide rail a13 drives the sliding rod 36 to move, and the sliding rod 36 drives the transmission rod 35 to move through the inclined surface, so that the fixing plate 34 moves forward to fix the parts. When the conveying plate 11 moves to the friction strip 14, the friction strip 14 drives the parts to rotate, so that the centering rod 44 falls into the part hole.

[0054] When the conveying plate 11 passes the guide rail b15, the guide rail b15 drives the piston rod 48 to move, so that the centering block 45 moves outward to center the part; when the conveying plate 11 moves to the forming mechanism 7, the clamping block a53 and the clamping block b54 clamp the part and push it into the hole pulling machine 51, and the hole pulling machine 51 pulls the hole on the part. After completion, the clamping block a53 and the clamping block b54 remove the part and release the part;

[0055] When the conveying plate 11 moves to the collecting mechanism 8 , the cylinder 73 drives the pushing cylinder 72 to push the parts and make them fall into the collecting box 72 .
