Nail, after claw clamping workpiece, then reverses pre-loading screw, so that pre-loading screw is embedded in workpiece surface, further fixes workpiece,
Anti- sliding stop, structure is simple, easy to use, effectively prevents falling and sliding for workpiece, the first mounting hole and the second installation
The penetrating mounting holes of hole composition, step up object can effectively in the chuck, allow claw the operation is stable of chuck, then pass through preload
Screw further steps up, and can effectively prevent workpiece and play occurs, improve machining accuracy.
Although above-mentioned case can effectively step up workpiece, each clamping requires to carry out clamping, clamping manually
Part working hour is too long, cannot quick location and installation.
Utility model content
It is mentioned above in the background art to solve the purpose of this utility model is to provide a kind of combined type Three-jaw fixture
Problem.
To achieve the above object, the utility model provides the following technical solutions: a kind of combined type Three-jaw fixture, including flange
Disk, on the ring flange uniform ring around set that there are three fan-shaped chuck bodies, and be provided with sliding slot on each fan-shaped chuck body, it is described
Claw is slidably connected on sliding slot, rack gear is welded on the claw, each fan-shaped chuck body is in symmetrical with rack gear
The heart is symmetrically arranged with bracket, is connected with shaft by bearing between two brackets, is equipped in the middle part of the shaft and rack gear
The gear being meshed, and one end of shaft is equipped with motor, the motor is fixedly mounted on fan-shaped chuck body, three institutes
The inner sidewall for stating claw is mounted on arc folder.
This setting starting motor drives shaft rotation, rotates three gears being separately mounted in three shafts,
Three gear rotations drive the corresponding rack gear being meshed therewith to realize that movement, three rack gear movements enable three claws to exist respectively
It is slided on corresponding sliding slot, therefore the arc folder of three claw inner sidewalls can be clamped workpiece.
Preferably, three arcs press from both sides to form a round clamping opening.
This setting workpiece to be processed can be placed in round clamping opening.
Preferably, each fan-shaped chuck body passes through two hexagon socket head cap screws and is fixedly mounted on ring flange.
This setting is fixed on fan-shaped chuck body on ring flange with hexagon socket head cap screw.
Preferably, the outer end face of the sliding slot is equipped with limited block.
This setting limited block is used to limit the position of claw.
Preferably, the quantity of the claw, arc folder, sliding slot, rack gear, gear and motor is three.
This setting sliding slot is used to the claw that is slidably connected, and rack gear is welded on claw, mainly utilizes motor band movable tooth
Wheel rotation, makes to be able to achieve movement with the rack gear that is meshed, so that claw can slide on the chute.
Preferably, the diameter of the ring flange is greater than the disk diameter of three fan-shaped chuck body assemblings.
This setting is convenient to assemble three fan-shaped chuck bodies on ring flange.
Compared with prior art, the utility model has the beneficial effects that this combined type Three-jaw fixture, clamping parts working hour
It is short, quickly location and installation workpiece, starting motor shaft rotation can be driven, three gears being separately mounted in three shafts are made
Rotation, three gear rotations drive the corresponding rack gear being meshed therewith to realize movement respectively, and three rack gears are mobile to make three cards
Pawl can slide on corresponding sliding slot, therefore the arc folder of three claw inner sidewalls can be clamped workpiece.
