The invention provides a chuck mechanism capable of quickly ejecting a workpiece for a numerical control machine tool. The chuck mechanism comprises claws and a top plate, wherein the top plate is arranged on the inner sides of a chuck body and is mounted in a transverse sliding chute in a sliding and clamping manner; further, the middle of the rear end of the top plate is connected to a reset inserted rod; the reset inserted rod is fixedly connected to a baffle plate and is inserted into an insertion drum in a sliding manner; the inserted rod and the insertion drum are also provided with a reset spring in a sleeving manner; the outer side of the rear end of the top plate is also connected to three groups of racks; further, the racks are connected to a linkage mechanism in a transmission manner; and the claws are also provided with threaded regulating rods. When the workpiece is inserted into an inner hole of the chuck body and the top plate is backwards pushed, a linkage shaft is enabled to rotate along with a linkage gear; the threaded regulating rods are driven to rotate; the claws are enabled to approach towards the middle to clamp the workpiece; locking blocks are inserted into square holes in the outer ends of the threaded regulating rods; the threaded regulating rods are locked; the reset spring is prevented from driving the top plate to return; the threaded regulating rods are driven to rotate; the claws are loosened; the threaded regulating rods are unlocked; and the top plate pushes out the workpiece under the push of the reset spring.
Description
technical field [0001] The invention belongs to the technical field of numerical control machining, and more specifically relates to a chuck mechanism of a numerical control machine tool with which workpieces can be quickly ejected. Background technique [0002] A chuck is a mechanical device used to clamp a workpiece on a machine tool. A machine tool accessory that clamps and positions workpieces by using the radial movement of movable jaws evenly distributed on the chuck body. The chuck is generally composed of three parts: the chuck body, the movable jaw and the jaw driving mechanism. [0003] For example, the patent application number is: CN201720813177.2, which discloses an electrically driven three-jaw chuck, including jaws, electric cylinder, front chuck, middle chuck, rear chuck, insulating ring, slip ring, positive pole Brushes, negative electrode brushes, bolts I, wires, bolts II, switches and balance pins, there are three claws in the axial array at the left end...
