The hydraulic three-jaw chuck is a standard configuration of the current numerical control lathe, is suitable for processing cylindrical parts, and has the advantages of high clamping efficiency, high self-centering precision, adjustable clamping force and the like; the hydraulic three-jaw chuck comprises a hydraulic system, a rotary oil cylinder, a pull rod, jaws and a chuck body, wherein one end side face of the chuck body is connected with a lathe, three jaws are uniformly arranged on the other end side face of the chuck body at intervals, the hydraulic system controls the rotary oil cylinder to extend out and retract, and the rotary oil cylinder drives the pull rod to enable the hydraulic chuck to drive the jaws to open or clamp a workpiece so as to clamp and fix the workpiece.
Hydraulic chucks are typically equipped with soft jaws. The soft claws are divided into an inner clamp and an outer clamp, the soft claws for clamping the workpiece when the chuck is closed are inner clamp type soft claws, and the soft claws for supporting the workpiece when the chuck is opened are outer clamp type soft claws. As shown in figure 1, the soft claw 1 is positioned with the claw seat 3 by an end face tooth socket and is fixed on the claw seat 3 through a screw and a T-shaped nut in the claw seat. When the hydraulic chuck works, the soft claws are driven by the claw seats to perform closing or opening motion to clamp or loosen a workpiece. When different workpieces are clamped, the clamping size of the hydraulic chuck is changed by changing the position of the soft claws on the claw seat.
The utility model solves the problems of clamping and processing square parts on a hydraulic three-jaw chuck, so as to realize the effects of adjusting the first part in place, quickly clamping and positioning in batches at the later stage and having high positioning precision.
SUMMERY OF THE UTILITY MODEL
In order to overcome the defects and shortcomings in the prior art, the utility model provides the hydraulic three-jaw chuck which is simple in structure, strong in universality, easy to manufacture, convenient to clamp, high in clamping efficiency and high in positioning precision and is used for clamping the square workpiece.
The technical scheme of the utility model is as follows: a hydraulic three-jaw chuck for clamping a square workpiece comprises a hydraulic system, a rotary oil cylinder, a pull rod, a chuck and jaws; the hydraulic system is connected with a rotary oil cylinder, the rotary oil cylinder is connected with a pull rod, and the pull rod is connected with a clamping jaw arranged on the chuck; the clamping jaws comprise an upper clamping jaw and two lower clamping jaws, and the included angle of the center line between the upper clamping jaw and the adjacent lower clamping jaw is 120 degrees; the clamping surface of the upper clamping jaw is in angular contact with one surface to be clamped of the square workpiece; the clamping surface of the lower clamping jaw is in surface contact with the other surface to be clamped of the square workpiece.
Furthermore, when the square workpiece is square, the two lower clamping jaws are the same in length and are symmetrically distributed along the center line of the chuck.
