[0057] The material grabbing finger driving mechanism is connected to the material grabbing finger 221 and is used to drive the material grabbing finger 221 to rotate.

[0058] The material grabbing finger 221 is connected to the material grabbing finger driving mechanism through the material grabbing finger fixing plate 222, and the material grabbing finger driving mechanism drives the material grabbing finger 221 to rotate, so as to transfer the pipe 300 from the loading unit 100 to the punching position; the material grabbing finger driving mechanism includes a rotary cylinder 223 and a material grabbing rotary seat 224, and the rotary cylinder 223 is arranged on the punching frame 210 through the material grabbing rotary seat 224, and the output end of the rotary cylinder 223 is connected to the material grabbing finger fixing plate 222.

[0059] When the first grabbing and conveying mechanism 220 is working, the grabbing fingers 221 grab the single pipe 300 conveyed from the feeding unit 100 , and the rotating cylinder 223 drives the grabbing fingers 221 to rotate 180° to convey the pipe 300 to the bottom of the punching mechanism 200 .

[0062] When the punching mechanism 230 is working, the position of the punching mechanism 230 is first adjusted by the horizontal sliding mechanism to ensure that the drill bit 234 is aligned with the target punching position of the pipe 300, and then the position of the first punching slider 233 is adjusted by the motor and the ball screw to make the drill bit 234 close to the surface of the pipe 300, and then the drill motor 236 is started to start drilling.

[0063] like Figure 6-Figure 9 As shown, the second material grabbing and transmission mechanism 240 includes:

[0064] The grabbing finger 221 is used to grab the pipe 300;

[0065] The material grabbing finger driving mechanism is connected to the material grabbing finger 221 and is used to drive the material grabbing finger 221 to rotate; and

[0066] The pushing mechanism is movably connected to the material grabbing finger driving mechanism through a cam mechanism, and is used to push the pipe 300 to the target position.

[0067] The material grabbing fingers 221 and the material grabbing finger driving mechanism of the second material grabbing and conveying mechanism 240 have the same structure as the material grabbing fingers 221 and the material grabbing finger driving mechanism of the first material grabbing and conveying mechanism 220 .

[0068] The pushing mechanism includes a pushing platform 241, on which a pushing base 242 is fixedly provided, and a pushing rod 243 is provided through the pushing base 242, and the pushing rod 243 is movably provided in the pushing base 242, and two ends of the pushing rod 243 are respectively connected with a pushing plate 244 and a connecting plate 245, and the connecting plate 245 is movably connected with the grasping finger driving mechanism through the cam mechanism, and the pushing plate 244 is used to push the pipe 300 to the target position, and a return spring 246 is also provided between the pushing base 242 and the connecting plate 245;

[0070] The pushing mechanism is movably connected to the grabbing finger driving mechanism of the second grabbing transmission mechanism 240 through a cam mechanism, so that the pushing mechanism does not need to be equipped with a driving mechanism, and can realize transmission with the grabbing finger driving mechanism of the second grabbing transmission mechanism 240 only through the cam mechanism. It has the advantage of being not easy to be damaged, reduces the setting of the driving mechanism, and saves costs.

[0071] The grabbing finger 221 of the second grabbing and conveying mechanism 240 grabs the pipe 300 after being punched by the punching mechanism 230 and rotates to the pushing platform 241 of the pushing mechanism. During this process, the connecting plate 245 of the pushing mechanism moves toward the grabbing finger driving mechanism of the second grabbing and conveying mechanism 240 under the action of the return spring 246, and the driven wheel 248 moves along the surface of the cam 247, and the pushing plate 244 of the pushing mechanism gradually approaches the pushing base 242; then, the second grabbing and conveying mechanism The material grabbing finger 221 of the mechanism 240 is released, and the pipe 300 is placed on the pushing platform 241. The material grabbing finger driving mechanism of the second material grabbing transmission mechanism 240 drives the material grabbing finger 221 to rotate back to the punching position. During this process, the driven wheel 248 is displaced under the action of the cam 247, and the driven wheel 248 drives the connecting plate 245 to gradually approach the pushing base plate 242, so that the pushing plate 244 gradually moves away from the pushing base plate 242. During this process, the pushing plate 244 pushes the pipe 300 to the target position. By setting a cam mechanism between the pushing mechanism and the material grabbing finger driving mechanism of the second material grabbing transmission mechanism 240, the unloading work of the pipe 300 is completed during the rotation of the material grabbing finger driving mechanism, which simplifies the operation process, shortens the working time, and effectively improves the working efficiency.

One end of the two material grabbing connecting rods 2214 is provided with a gear 2216, which is meshed with the rack 2215. The other end of the material grabbing connecting rod 2214 is movably connected to a finger pressure plate 2217. The grabbing finger 221 adopts the above-mentioned structure to enable the grabbing connecting rod 2214 to open at an angle exceeding 180°, thereby ensuring that the grabbing finger 221 will not collide with the pipe 300 during rotation, reducing the occupied area of ​​the punching unit 200 and improving the compactness between the various mechanisms of the punching unit 200. The grabbing finger 221 adopting the gear rack structure also has the advantage of being not easily damaged. The use of the finger pressure plate 2217 to clamp the pipe 300 can also effectively reduce the occupied area of ​​the punching unit 200, improve the compactness between the various mechanisms of the punching unit 200, and ensure the stability of grabbing the pipe 300.

[0073] When the punching unit 200 is working, the first grabbing and conveying mechanism 220 grabs a single pipe 300 conveyed from the loading unit 100, and conveys the pipe 300 to the bottom of the punching mechanism 200. At this time, the second grabbing and conveying mechanism 240 grabs the pipe 300, and at the same time, the first grabbing and conveying mechanism 220 releases the pipe, and then the first grabbing and conveying mechanism 220 rotates back to the initial position to prepare to grab the next pipe 300; after the second grabbing and conveying mechanism 240 grabs the pipe 300 at the punching position, the punching mechanism 230 punches the pipe 300. After the punching is completed, the second grabbing and conveying mechanism 240 grabs and rotates the pipe 300 to the pushing platform 241, and then the second grabbing and conveying mechanism 240 releases the pipe 300 and rotates to the punching position. During this process, the pushing plate 244 pushes the pipe 300 to the target position for unloading under the action of the cam mechanism.
