Abstract
The invention relates to a hydraulic three-jaw chuck. When the hydraulic three-jaw chuck is used, a lathe spindle rotates, a small bevel pinion drives a pinion gear wheel, a hydraulic cylinder rotates along with the bevel gear wheel, jaws radially move, stress on a cylindrical piston is increased after the hydraulic three-jaw chuck is in contact with a workpiece, a conical spiral spring is compressed, the cylindrical piston moves towards stator blades, hydraulic oil is compressed and pushes rotor blades to rotate, the jaws are subjected to radial micro-feeding, the bevel gear wheel continuously rotates to reach a certain angle, and the cylindrical piston can be reset, continues to rotate and repeats previous movement until the workpiece is completely clamped. The hydraulic three-jaw chuck has the advantages of simple structure, reliability in work, high force increasing ratio and excellent economical efficiency and feasibility.
Description
Technical field
The invention belongs to Digit Control Machine Tool field, be specifically related to a kind of hydraulic pressure scroll chuck.
Background technology
Traditional lathe relies on workman to clamp by hand as the work of scroll chuck on lathe, milling machine, most pressing plate, adjustment bolt and hold-down bolts etc. of adopting carry out the sequence of operations such as artificial fine setting, this has not only increased workman's labour intensity, and required clamping force is very large, also usually there is not clamping situation, be difficult to ensure the even of clamping force, hindered the raising of productivity ratio.
Summary of the invention
The present invention has overcome above shortcoming provides a kind of novel hydraulic scroll chuck.
The present invention realizes by following technological means, a kind of hydraulic pressure scroll chuck, comprising: 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;
Wherein, the tight interlock bevel gear wheel of bevel pinion, bevel gear wheel groove connecting cylinder piston, the plunger other end is contained in the hole of stator vane, conical helical spring is equipped with in end, and hydraulic cylinder connects claw and is connected with bevel gear wheel, the hydraulic oil rotor blade that is connected;
When work, lathe spindle acts on bevel pinion, and bevel pinion drives bevel gear wheel, hydraulic cylinder rotates thereupon, and claw moves radially, the stressed increase of plunger after contact workpiece, compression conical helical spring, plunger moves to stator vane, the pressurized contracting of hydraulic oil, the rotation of liquid-driving rotor blade, the radially micro-feeding of claw, bevel gear wheel continues rotation to a certain angle, and plunger will reset, be rotated further, will repeat last motion until workpiece is clamped completely; Wherein the bevel gear wheel back side processes groove, and plunger one end coordinates with groove, and the other end is contained in the hole of hydraulic cylinder stator vane, and conical helical spring is equipped with in end, and cylinder plunger is under conical helical spring effect, and one end contacts with groove all the time.
Advantage of the present invention is simple in structure, and reliable operation can reach higher force increasing ratio, has good economy and feasibility, without artificial fine setting.
