Abstract
The utility model relates to a hydraulic three-jaw chuck. A lathe spindle rotates a small bevel gear to drive a large bevel gear; a hydraulic cylinder rotates with the large bevel gear; jaws move radially to contact with a workpiece before stress of a cylindrical piston increases; a conical helical spring is compressed; the cylindrical piston moves to stator vanes; hydraulic coil is compressed and pushes rotor vanes to rotate; the jaws are micro-fed radially; the large bevel gear continues to rotate at a certain angle until the cylindrical piston restores; the large bevel gear continues to rotate; and the former movements repeat until the workpiece is clamped completely. The hydraulic three-jaw chuck has the advantages of simple structure, reliability in operation, high boost ratio, and good economy and feasibility.
Description
Technical field
The utility model belongs to the Digit Control Machine Tool field, is specifically related to a kind of hydraulic pressure scroll chuck.
Background technology
Traditional lathe relies on the workman to clamp by hand as the work of scroll chuck on lathe, the milling machine, sequence of operations such as majority adopts that pressing plates, adjustment bolt and hold-down bolt etc. are manually finely tuned, this has not only increased working strength of workers, and required clamping force is very big, the not tight situation of folder is also usually arranged, be difficult to guarantee the even of clamping force, hindered the raising of productivity ratio.
The utility model content
The utility model has overcome above shortcoming provides a kind of novel hydraulic scroll chuck.
The utility model is realized by following technological means, a kind of hydraulic pressure scroll chuck comprises: chuck body end cap, bevel pinion, bevel gear wheel, plunger, conical helical spring, hydraulic cylinder, claw, stator vane, the mechanism of changing oil, rotor blade, cylinder end caps, hydraulic oil, chuck body;
The tight interlock bevel gear wheel of bevel pinion wherein, the bevel gear wheel groove connects plunger, and the plunger other end is contained in the hole of stator vane, and conical helical spring is equipped with in the end, hydraulic cylinder connects claw and links to each other with bevel gear wheel, the hydraulic oil rotor blade that links to each other;
During work, lathe spindle acts on the bevel pinion, and bevel pinion drives bevel gear wheel, hydraulic cylinder rotates thereupon, and claw moves radially, the stressed increase of plunger behind the contact workpiece, the compression conical helical spring, plunger moves to stator vane, the pressurized contracting of hydraulic oil, liquid promotes the rotor blade rotation, the radially little feeding of claw, bevel gear wheel continue rotation to a certain angle, and plunger will reset, be rotated further, will repeat last motion up to workpiece is clamped fully; Wherein the bevel gear wheel back side processes groove, and plunger one end cooperates with groove, and the other end is contained in the hole of hydraulic cylinder stator vane, and conical helical spring is equipped with in the end, and the cylinder plunger is under the conical helical spring effect, and an end contacts with groove all the time.
The utility model has the advantages that simple in structurely, reliable operation can reach higher force increasing ratio, has good and economic and feasibility, need not artificial fine setting.
