The cylinder drives the first gear to rotate through the first rack, the first gear rotates to drive the gear ring to rotate, the gear ring drives the duplicate gear to rotate, and the third gear drives the second rack to move linearly, so that clamping or loosening of the workpiece by the clamping jaws is realized; the application range of the chuck can be enlarged by enlarging the gear ring, and the defect that the traditional pneumatic chuck connecting rod generates flexibility is avoided.
Description
Technical Field
The utility model relates to a chuck technical field specifically is a rack and pinion air chuck.
Background
The conventional pneumatic chuck is controlled by a cylinder to realize synchronous motion of a plurality of jaws, and because the travel distances of the motion of the jaws are consistent, the conventional pneumatic chuck is only suitable for clamping rod bodies with square or circular cross sections; in addition, in order to guarantee the synchronous motion of a plurality of jack catchs, be provided with slider and the spout of being connected with the connecting rod on the conventional air chuck, drive the connecting rod through the removal of slider and remove to drive the removal of jack catchs, the connecting rod has length restriction, if the connecting rod is too long, the operating time is long can produce the flexibility, destroys the performance of chuck. In conclusion, how to expand the application range of the air chuck becomes a problem which needs to be solved urgently by researchers of the company.
SUMMERY OF THE UTILITY MODEL
The to-be-solved technical problem of the utility model is: how the application range of the air chuck can be expanded.
The utility model provides a rack and pinion air chuck, which comprises a shell, wherein the shell is provided with a plurality of guide grooves which are uniformly distributed, a clamping jaw is clamped in the guide grooves, and a second rack is arranged on the side surface of the clamping jaw;
a gear ring is movably connected to the middle of the shell, a plurality of first gears and a plurality of duplicate gears are meshed with the gear ring, the first gears, the duplicate gears and the guide grooves correspond to each other, a first rack is meshed with the first gears, and one end of the first rack is connected with an air cylinder;
the dual gear comprises a second gear and a third gear which are arranged in parallel, the second gear is meshed with the gear ring, and the third gear is meshed with the second rack.
The cylinder drives the first gear to rotate through the first rack, the first gear rotates to drive the gear ring to rotate, the gear ring drives the duplicate gear to rotate, and the third gear drives the second rack to move linearly, so that clamping or loosening of the workpiece by the clamping jaws is realized; the application range of the chuck can be enlarged by enlarging the gear ring, and the defect that the traditional pneumatic chuck connecting rod generates flexibility is avoided.
Furthermore, the second gear with the third gear passes through the connecting rod and is connected, the connecting rod both ends all are equipped with the location step, the location step joint respectively the second gear hole with the third gear hole. The design reduces the processing difficulty of the duplicate gear, and the arrangement of the positioning steps ensures that the second gear and the third gear are concentric.
