Utility model content
Therefore, for above-mentioned problem, the utility model proposes a kind of straight indexing mechanisms of ring waist, and which solve existing indexings
The technical problem that the rotational stability in mechanism village is bad, jitter is larger.
To achieve the above object, the utility model uses following technical scheme: a kind of straight indexing mechanism of ring waist, including machine
Frame and shaft, turn device, differential gear, negative pressure system, driving device in rack, the driving device include being set to
The toothed disc being connected in shaft with motor drive, the negative pressure system include the gas distribution plate in shaft, the turn device
Including substrate, cursor, suction tray, race, it is rotatably equipped with support plate in the shaft, is located at the another of substrate in the shaft
Side is equipped with the second support plate, and connecting rod, second support plate and gear are equipped between the support plate and the second support plate
Disk is fixedly connected, the differential gear include the eccentric disc being fixedly arranged in rack, the swing arm being rotatably arranged on eccentric disc, can
The connecting rod being rotatably arranged on substrate, the connecting rod are hinged and connected with swing arm, and the swing arm is equipped with directive wheel, the eccentric disc
It is equipped with guide groove, the directive wheel is slided along guide groove, and the eccentric disc is located at the outside of support plate, the swing arm, support
The center of disk articulated section and the axle center of directive wheel shift to install.
Further, the substrate is equipped with a hollow vent board, and the vent board is connected with gas distribution plate, described logical
Gas plate is connected with suction tray.
By using preceding solution, the beneficial effects of the utility model are: the straight position runner of this ring waist by support plate,
The setting of second support plate, connecting rod forms support, will drive support plate, the rotation of the second support plate when toothed disc rotation, from
And swing arm is driven to run, at this time by directive wheel along the sliding of guide groove, swing arm can be made to swing, drive connecting rod swing, thus
The velocity variations of substrate are driven, the stabilization row of this differential gear is preferable, as long as timing replacement guide wheel.In addition, passing through position
