The specific embodiment
For technological means, creation characteristic that the present invention is realized, reach purpose and effect is easy to understand, below in conjunction with concrete diagram, further set forth the present invention.
Shown in Fig. 3,4,5,6, a kind of multi-spindle carriage in-phase transmission mechanism, it comprises a transmission device 1, a ball-screw apparatus 2 and some main shaft plankers 3, one end of described ball-screw apparatus 2 links to each other with described transmission device 1, and its other end is connected with each main shaft planker 3 by bar linkage structure 4.
Described bar linkage structure 4 comprises master connecting-rod 41 and the connecting rod 42, connecting rod 43 and the connecting rod 44 that are connected with each main shaft planker, and the top of described connecting rod 42 connects master connecting-rod 41, and the bottom connects connecting rod 43 and connecting rod 44 successively, and the bottom of connecting rod 44 connects main shaft planker 3; Be connected to each other by hinge between described connecting rod 42, connecting rod 43 and the connecting rod 44.
Be provided with planker 5 between described ball-screw apparatus 2 and the bar linkage structure 4, described planker 5 is provided with pull bar 51, and described ball-screw apparatus 2 is connected with described planker 5, and described pull bar 51 is connected with master connecting-rod 41 in the described bar linkage structure 4 by a drive link 52.
Described transmission device 1 is a servomotor.
When processing the ball cage of six windows, by transmission device 1 as power source, drive ball-screw apparatus 2 and planker 5 by it, and pass through the six roots of sensation master connecting-rod 41 synchronous interlocks that drive link 52 drives in the described bar linkage structure 4, thereby control corresponding main shaft planker 3 by the pull bar on the planker 5 51.
