The first arc-shaped chain 33.3 section is closer to the feeding station A, and the second arc-shaped chain section is closer to the discharging station C. In order to avoid interference of the holding part with the crankshaft, in the initial state, the connecting piece 51 is located on the lower chain strand 32.2, the height of the holding part 6 being lower than the bearing seat 7.
In this embodiment, as shown in fig. 1 and 3, the supporting portion 6 and the corresponding carrying seats 7 are provided with two groups, the carrying seats 7 are disposed at the upstream and the middle of the frame 1, two ends of the frame 1 are provided with a feeding station a (i.e. the position of the carrying seat located at the most upstream) and a discharging station C (i.e. the most downstream position that the supporting portion can reach), a plurality of buffer stations B are disposed between the feeding station a and the discharging station C, and the buffer stations B (i.e. the positions of the carrying seats between the feeding station and the discharging station). In actual production, as shown in fig. 8, in order to improve the conveying efficiency, two synchronous conveying devices W are arranged in parallel, so that two synchronous conveying devices W for automobile crankshafts can respectively and simultaneously convey two crankshafts of different types, or two synchronous conveying devices W for automobile crankshafts can both convey crankshafts of the same type; the two automobile crankshaft synchronous conveying devices W are matched with the conveying device R for use, the conveying device R mainly comprises a portal frame, a conveying frame movably arranged on the portal frame, a driving device for driving the conveying frame to transversely move and a bearing seat arranged on the conveying frame (the bearing seat has the same structure as that of the bearing seat arranged on the frame), the bearing seat on the conveying frame corresponds to the blanking stations of the two automobile crankshaft synchronous conveying devices, and the crankshaft is conveyed to the bearing seat of the conveying frame through the synchronous conveying devices finally, and then the conveying frame conveys the crankshaft to the feeding position of the crankshaft conveying device E.

Referring to fig. 1 and 2, when the driving motor 4 drives the driving wheel 31 to rotate, the connecting piece located on the lower chain section 33.2 moves towards the first arc-shaped chain section 33.3, then the connecting piece reaches the bottom end of the first arc-shaped chain section 33.3 and gradually climbs to the top end of the first arc-shaped chain section 33.3, the supporting part 7 located at the most upstream ascends towards the crankshaft on the feeding station a, when the supporting part 6 is consistent with the height of the bearing seat 7 on the feeding station a, the supporting part 6 supports the crankshaft D, then the supporting part 6 continues to ascend to enable the crankshaft D to be separated from the support of the bearing seat 7, then the connecting piece located at the top end of the first arc-shaped chain section 33.3 moves towards the second arc-shaped chain section 33.4 along the upper chain section 33.1, so that the crankshaft D moves towards the buffer station B, and the connecting piece 51 reaches the top end of the second arc-shaped chain section 33.4 and gradually descends back to the bottom end of the second arc-shaped chain section 33.4; correspondingly, the supporting part 6 supports the crankshaft D, so that the crankshaft D is positioned above the bearing seat A of the buffer station B, and then the supporting part 6 gradually descends, so that the crankshaft is stably placed on the bearing seat 7. Finally, the connecting element 51 at the bottom end of the second curved strand 33.4 is returned to the lower strand 33.2. In the moving process of the connecting piece, the rotating shaft can rotate along with the movement of the connecting piece because the connecting piece is fixedly connected with the rotating shaft.
The crankshaft conveying process is a conveying period, and it can be understood that when the synchronous conveying device for the automobile crankshafts finishes a conveying period, the crankshaft D positioned on the buffer station B or the crankshaft positioned on the feeding station A can be conveyed to the next station until the crankshaft exists on the discharging station C, and then the conveying is stopped.
