Among them, the first 711 and second 810 drive chains may be toothed chains.
In use, as shown in fig. 7, the connecting rod neck shafts a of the automobile crankshaft are generally four, the two coaxial connecting rod neck shafts a in the middle are in one group, and the two coaxial connecting rod neck shafts a at the two ends are in one group, so that a total of four grinding mechanisms 6 are required to process the connecting rod neck shafts a simultaneously, and two different follower mechanisms are required to be matched with the grinding mechanisms 6 to polish the crankshaft because the two groups of connecting rod neck shafts a are in opposite directions.
When the crankshaft is polished, the rotation of the driving motor 2 drives the crankshaft to rotate, the chuck two 4 is connected with the crankshaft and synchronously rotates, the gear two 710 can drive the gear one 709 to rotate through the transmission chain, the gear one 709 can drive the rotating plate one 703 to rotate through the follow-up rotating shaft one 702 and further drive the connecting column one 704 to rotate, the rotation of the connecting column one 704 is transmitted to the lifting column 707, the rotation of the connecting column one 704 is decomposed into lifting sliding of the lifting column 707 inside the sliding frame 706 and reciprocating movement of the sliding frame 706 inside the guide rail one 705, and the movement of the lifting column 707 and the sliding frame 706 drives the grinding mechanism 6 to correspondingly move through the supporting plate 5, so that the grinding mechanism 6 can correspondingly change positions along with the rotation of the connecting rod neck shaft A while polishing the connecting rod neck shaft A, and the contact force between the abrasive belt 614 and the connecting rod neck shaft A is unchanged, and the grinding mechanism 6 can uniformly polish the connecting rod neck shaft A.
The second follower 8 operates in the same manner as the first follower 7, except that when the second link 803 changes the position of the grinding mechanism 6 by driving the second follower 807, the rotation of the second follower 807 following the second link 803 is decomposed into the up-and-down movement of the telescopic rod 804 and the reciprocal sliding of the sliding column 806 inside the second guide 805.
The key point of the operation of the first follower 7 and the second follower 8 is that the axial distance between the first follower rotating shaft 702 and the connecting post 704 or between the second follower rotating shaft 801 and the connecting post 803 is the same as the axial distance between the journal shaft of the crankshaft and the journal shaft a, and the crankshafts of the first follower rotating shaft 702 and the second follower rotating shaft 801 synchronously rotate, so that the rotating structure formed by the first follower rotating shaft 702, the first rotating plate 703 and the connecting post 704 or the rotating structure formed by the second follower rotating shaft 801, the second rotating plate 802 and the connecting post 803 and two groups of different journal shafts a have the same rotating path, and the grinding mechanism 6 can be moved close to the journal shaft a at any time.
When not in operation, the structure of the first follower shaft 702, the first rotating plate 703 and the first connecting post 704 is exactly the same as the structure of the second follower shaft 801, the second rotating plate 802 and the second connecting post 803, so that after the crankshaft is placed on the belt 614, the positions of the two sets of connecting rod necks a are exactly synchronous with the rotation structure of the first follower shaft 702, the first rotating plate 703 and the first connecting post 704 or the rotation structure of the second follower shaft 801, the second rotating plate 802 and the second connecting post 803.
The rest of the structure is the same as that of embodiment 2.
