As shown in fig. 11, when the second receiving plate 433 rotates, the second receiving plate 433 receives two steel pipes 5 at the end of the storage rack 2 from the two grooves 4122 near the storage rack 2 from below, and the four grooves 4122 at the end of the second receiving plate 433 far from the storage rack 2 receive four steel pipes 5 on the first receiving plate 412 in a group of steel pipes 5.

As shown in fig. 12, when the second receiving plate 433 continues to rotate in the original rotation direction, the second receiving plate 433 is higher than the first receiving plate 412, and the steel pipe 5 is lifted up. The two polished steel pipes 5 are fed out and rotated, and when the second receiving plate 433 is as high as the first receiving plate 412, the four steel pipes 5 fall down and are placed on the four grooves 4122 of the first receiving plate 412 again. The transfer of the group of steel pipes 5 is completed.

When the two steel pipes 5 at the tail end of the storage rack 2 are carried away by the second receiving plate 433, the other steel pipes 5 on the storage rack 2 roll towards the direction close to the end part of the storage rack 2, and the gap between the two steel pipes 5 after being carried away is filled.

In the process of one rotation of the second receiving plate 433, the two steel pipes 5 at the ends of the two storage racks 2 are conveyed to the two grooves 4122 of the first receiving plate 412, and simultaneously, the two steel pipes 5 on the first receiving plate 412 are changed from the two grooves 4122 close to the storage racks 2 to the two grooves 4122 of the corresponding milling machine body 3, and the two ground steel pipes 5 are removed from the two grooves 4122 of the corresponding milling machine body 3.

The blanking motor 42 is connected with the milling machine body 3 and linked with the milling machine body. After the milling machine body 3 finishes polishing the steel pipe 5, the blanking motor 42 is started while the air cylinder 321 returns, so that the second bearing plate 433 transfers the steel pipe 5.

Referring to fig. 13, the transport device 4 further includes a blanking bracket 44 and a blanking conveyor belt 45. The blanking support 44 is fixed on the ground and is perpendicular to a connecting line of the two milling machine bodies 3, one end of the blanking support 44 is connected with and higher than the end part of the first connecting plate 412, the other end of the blanking support 44 is connected with and higher than the blanking conveyor belt 45, and the distance between the blanking support 44 and one end of the blanking conveyor belt 45 is lower. The two ground steel pipes 5 lifted by the second receiving plate 433 are discharged to the discharging holder 44.

The blanking brackets 44 are equidistantly arranged along the connecting line of the two milling machine bodies 3 to stably convey the steel pipes 5. The blanking conveyor belt 45 has a structure substantially the same as that of the feeding conveyor belt 11, and is different therefrom in that a fixing plate 111 is provided with a limit post 451 vertically arranged along the length extension direction thereof, the limit post 451 adjacent to the blanking bracket 44 is a first limit post 4511, the other side is a second limit post 4512, the first limit post 4511 corresponds to the second limit post 4512 in position, the first limit post 4511 is slightly higher than the roller 112 and lower than the end of the blanking bracket 44, and the second limit post 4512 is higher than the first limit post 4511. Since the steel pipe 5 slides down from the blanking bracket 44, when the steel pipe 5 slides down on the blanking conveyor belt 45, the steel pipe 5 first collides with the second stopper 4512 due to its own certain speed and inertia. The second limit column 4512 is higher, and intercepts the rolled steel pipe 5 and slows down the speed of the steel pipe, so that the steel pipe 5 is suddenly stopped on the blanking conveyor belt 45. When two steel pipes 5 slide onto the blanking conveyor belt 45 from the blanking bracket 44 at the same time, the two limiting columns 451 limit the two steel pipes 5 from being sent out on the blanking conveyor belt 45, and prevent the two steel pipes 5 from sliding out of the blanking conveyor belt 45.

When the steel pipe 5 is placed on the lower clamping block 3222, the output end of the second cylinder 3212 drives the pressing plate 323 to press the top surface of the steel pipe 5, and the side wall of the steel pipe 5 is in fit with the arc surface of the pressing plate 323, so that the steel pipe 5 is clamped more stably.

Example three: referring to fig. 16 and 17, for the utility model discloses a steel pipe end milling machine system with clamping mechanism, its structure is basically the same as second embodiment, its difference lies in, for making the centre gripping of steel pipe 5 more firm, second cylinder 3212 end fixing holder 324, holder 324 includes horizontal rod 3241, connecting rod 3242 and splint 3243, horizontal rod 3241 is including fixing the first horizontal rod 32411 in second cylinder 3212 output end bottom, articulated connecting rod 3242 is rotated respectively at first horizontal rod 32411 both ends, the other end of two connecting rods 3242 respectively rotates the one end of articulated splint 3243.

The horizontal rod 3241 further includes a second horizontal rod 32412, the second horizontal rod 32412 has a longer length than the first horizontal rod 32411, and both ends of the second horizontal rod 32412 are hinged to the centers of the two clamping plates 3243. The opposite surface of the other end of the clamping plate 3243 is provided with a second clamping groove 3252 which is internally recessed, the side surface of the second clamping groove 3252 is an arc surface, the arc surface is radially consistent with the steel pipe 5, and the arc surface is provided with second wear-resistant grains 342 so as to better stabilize the steel pipe 5.

When the end of the steel pipe 5 is placed in the milling machine body 3, the output end of the second cylinder 3212 moves vertically downwards, the second horizontal rod 32412 first contacts the top of the steel pipe 5, while the end of the second cylinder 3212 still moves, the first horizontal rod 32411 moves vertically downwards, the first horizontal rod 32411 pushes the connecting rod 3242, the end of the clamping plate 3243 hinged to the connecting rod 3242 is pushed by the connecting rod 3242 to move to a position far away from the center of the second horizontal rod 32412 by taking the end of the clamping plate 3243 hinged to the second horizontal rod 32412 as a fulcrum, and the other ends of the two clamping plates 3243 move towards each other. The clamping plates 3243 are long, so that the ends of the two clamping plates 3243 moving towards each other just clamp the side wall of the steel pipe 5.
