Abstract
The invention discloses a diaphragm chuck centering device. The device comprises a clamp body, a diaphragm, a plurality of clamping jaws, a plurality of ejector rods, a plurality of bearing nails and a gear workpiece and further comprises a pre-expansion ring, the clamp body is of a circular structure, the diaphragm is arranged to be of a circular structure, the periphery of the diaphragm is arranged on the front face of the clamp body through a bolt, the clamping jaws are evenly arranged on the diaphragm according to the same circumference, the ejector rods are evenly arranged on the back portion of the diaphragm, and are used for pushing the diaphragm to be deformed, the bearing nails are evenly arranged on a circle formed by the clamping jaws according to the same circumference, and the pre-expansion ring is arranged above the bearing nails, and is used for preventing the bearing nails from abrading the gear workpiece. The diaphragm chuck centering device is specially used for a gear workpiece centering clamp, the higher centering precision can be provided, the larger clamping force can be provided for the gear workpiece, and the workpiece is not prone to being damaged.
Description
Technical field
The present invention relates to a kind of chuck of diaphragm centring means, belong to grip device technical field.
Background technology
At present, existing elastic collet chuck is during as gear workpieces centering and clamping apparatus, and often, because the distortion of collet chuck is little, insufficient clamping force, makes gear workpieces adding man-hour, is subjected to displacement, thereby affects machining accuracy.
Summary of the invention
Object: in order to overcome the deficiencies in the prior art, the invention provides a kind of chuck of diaphragm centring means.
Technical scheme: for solving the problems of the technologies described above, the technical solution used in the present invention is:
A kind of chuck of diaphragm centring means, comprises clamp body, diaphragm, multiple claw, many push rods, multiple supporting nail, gear workpieces, also comprises pre-tensioner ring, and described clamp body is set to circular configuration; Described diaphragm arrangement is circular configuration, and diaphragm periphery is arranged at clamp body front by bolt; Described multiple claw is arranged on diaphragm by same even circumferential; Described many push rods are evenly arranged at diaphragm back, produce distortion for promoting diaphragm; Described multiple supporting nail is arranged at by same even circumferential in the circle of multiple claws formation; Described pre-tensioner ring is arranged at multiple supportings side of nailing on, for preventing the wearing and tearing of supporting nail to gear workpieces.
Also comprise roller protector, described roller protector is socketed in the gear of gear workpieces, for preventing that claw from contacting with the gear of gear workpieces.
As preferred version, described claw quantity is set to six.
As preferred version, described supporting nail quantity is set to three.
As preferred version, described diaphragm thickness is set to 6mm; Described diaphragm material adopts 65Mn.
Beneficial effect: chuck of diaphragm centring means provided by the invention, be specifically designed to gear workpieces centralizer, higher centering precision can be provided; And can provide larger clamping force to gear workpieces, and protection workpiece is not easily damaged.
