Examples:
referring to fig. 1-3, the present utility model provides a technical solution: a indexing mechanism for a four-axis tightening machine, comprising:
a lower installation shell 1 with a hollow upper opening and an operation plate 2 detachably connected to the upper opening of the lower installation shell 1; as shown in fig. 1, the operation panel 2 is mounted on the upper side of the lower mounting case 1, and closes the upper opening of the lower mounting case 1.
The sliding grooves 3 are formed in four, the four sliding grooves 3 are formed in an annular array shape and are formed in the operation plate 2, sliding blocks 4 are connected in a sliding mode in the sliding grooves 3, clamping arms 5 are arranged at the upper ends of the sliding blocks 4, and connecting seats 6 are arranged at the bottom ends of the sliding blocks 4; the clamping arm 5, the sliding block 4 and the connecting seat 6 are integrated, and the clamping arm 5, the sliding block 4 and the connecting seat 6 can synchronously move.
The movable shaft 8 is in sliding connection with the lower surface of the lower mounting shell 1, and the up-and-down movement of the movable shaft 8 drives the connecting seat 6, the sliding block 4 and the clamping arm 5 to move.
Preferably, the two opposite connecting seats 6 are connected in a supporting way through springs 7. The connection is supported by the springs 7, so that the two opposite connecting seats 6 are kept in a tensioning state, and the restoring trend is realized.
