Abstract
The utility model belongs to the technical field of machine tool fixtures, and relates to a high-speed hollow three-jaw chuck. The high-speed hollow three-jaw chuck comprises a hollow cylindrical chuck body. The front end face of the chuck body is provided with three radial sliding grooves which are evenly distributed. The sliding grooves are internally and respectively provided with a claw capable of sliding along the corresponding sliding groove. The hollow part of the chuck body is provided with a sliding block which is driven by a hydraulic cylinder to move in the axial direction. The sliding block is provided with three oblique sliding grooves, and a certain angle is formed between the axis of the chuck body and each oblique sliding groove. The three oblique sliding grooves are evenly distributed in the cylindrical face of the sliding block, and the tail of each claw is provided with an inclined slide rail capable of sliding in the corresponding oblique sliding groove. The high-speed hollow three-jaw chuck has the advantages of being high in workpiece loading and unloading speed, high in production efficiency, large in clamping force, capable of clamping large workpieces and small workpieces and suitable for high-speed machine tool fixtures.
Description
Technical field
The utility model belongs to jig technical field, refers in particular to a kind of high speed hollow scroll chuck.

Jig is as a vitals in machining, and its function is to clamp workpiece to be processed, provides moment of torsion and axial force to processing work, realizes the revolution of workpiece simultaneously under the effect of power set.Conventional digital control lathe clamper mainly contains three-jaw self-centering chuck, four-jaw chuck and floral disc etc., these fixtures are general all for the part of clamping small volume, the clamping force size range less and clamping parts of fixture is also less, when clamping, need to unscrew or screw that workpiece is loaded and unloaded by manually operating, replacing workpiece is cumbersome, each workpiece will be loaded and unloaded many times adding man-hour repeatedly, need a large amount of human resources, the cycle of simultaneously each workpiece processing is also longer, the efficiency of producing is very low, and production cost is high.
Summary of the invention
The purpose of this utility model is to provide the high speed hollow scroll chuck that a kind of workpiece loading and unloading speed is fast, production efficiency is high, clamping force is large, can clamp large small workpiece.
The purpose of this utility model is achieved in that
A kind of high speed hollow scroll chuck, comprise the columniform chuck body of hollow, on the front end face of chuck body, be provided with three uniform chutes radially, in chute, be respectively arranged with the claw that can slide along chute, the hollow bulb of described chuck body is provided with slide block, by Driven by Hydraulic Cylinder, it moves axially slide block, on slide block, be provided with the oblique chute angled with chuck body axis, described oblique chute is evenly equipped with three on the face of cylinder of slide block, and the afterbody of described claw is provided with the oblique slide rail that can slide in described oblique chute.
The radius of the oblique chute arranging on upper above-mentioned slide block strengthens from front to back gradually, and the oblique slide rail on the claw corresponding with oblique chute also strengthens from front to back gradually apart from the distance of axis.
The radius of the oblique chute arranging on above-mentioned slide block reduces from front to back gradually, and the oblique slide rail on the claw corresponding with oblique chute also reduces from front to back gradually apart from the distance of axis.
The concrete structure of above-mentioned claw is: the inner side of base is provided with described oblique slide rail, front side and is provided with T-slot, on T-slot, be set with contiguous block, on contiguous block, be provided with screwed hole, the fixture block of clamping work pieces is clamped in fixture block and contiguous block on the T-slot on base by screw rod, and fixture block and contiguous block are clamped in the radially installation site of the diverse location capable of regulating fixture block on the T-slot of base.
The utility model compared to existing technology outstanding and useful technique effect is:
1, claw of the present utility model radial parallel on chuck body moves, and the contact-making surface after clamping work pieces is large, adopts a hydraulic-driven in addition, and chucking power large (chucking power of comparing existing product improves 30%) is little to the infringement of workpiece.
2, the utility model, because blessing power increases, has improved work quality and security, can realize ultrahigh speed rotation.
3, of the present utility model simple in structure, lightweight (compare existing fixture and alleviate 100% weight), has realized small-sizedly, has improved operating efficiency.
4, the utility model adopts specific alloy steel making, has realized that intensity is large, precision is high, the life-span is long.
5, the speed of the utility model workpiece loading and unloading is fast, production efficiency is high, clamping force is large, can clamp large small workpiece, is applicable to high-speed machine tool fixture.
