Abstract
The utility model discloses a kind of hydraulic pressure handle of a knife, comprise body, collet chuck, set screw, pin, seal, pinching screw, holding screw, steel ball, sealing screw, burnishing-in ball, hole A, hole B, hole C, cavity D, burnishing-in ball carries out burnishing-in effect to hole inwall, improve the surface roughness of hole inwall, make sealing effectiveness better, higher locking pressure is provided.Body one end is installed on CNC milling machine, the other end is provided with the collet chuck be convenient to cutter and inserted, screw pinching screw and can make that hydraulic oil cavity reduces, pressure increases, causes collet chuck to produce inside contraction distortion, locking cutter, rotating pinching screw in the other direction can make oil pressure reduce, collet chuck restores to the original state, and takes out cutter.
Description
Technical field
The utility model relates to a kind of hydraulic pressure handle of a knife, specifically clamps the fine finishining of the instruments such as the milling cutter on each metalloid milling machine.
Background technology
Current each model milling machine and horizontal Machining centers, the method that part processing is commonly used is on machine tool chief axis, install handle of a knife, cutter, with power source, the corresponding cutting tool of main axis.The body lower end of conventional collet chuck nut type handle of a knife is provided with a locking nut, and cutter clamping, in handle of a knife body lower end, is locked by locking nut.This type of Knife handle structure is simple, but when processing dark shrinkage pool locking nut easily and rapidoprint interfere.Conventional heat-shrinkable knife handle, cutter clamping is in the clamping chamber of handle of a knife body lower end, and handle of a knife body diameter is less, can complete the processing to deep hole, but handle of a knife itself needs cutter to be loaded in clamping chamber and take out with heater, very loaded down with trivial details during use.The solid handle of a knife in conventional side, produce thrust locking cutter by the solid screw in side, the cutter of monolateral like this locking, not only coupling mechanism force is little, and cutter axial line and handle of a knife axial line offset, and affect the axiality of cutter and main shaft.
Summary of the invention
For solving the problem, the utility model proposes a kind of hydraulic pressure handle of a knife.
A kind of hydraulic pressure handle of a knife, comprise body, collet chuck, set screw, pin, seal, pinching screw, holding screw, steel ball, sealing screw, burnishing-in ball, hole A, hole B, hole C and cavity D, described body one end is installed on CNC milling machine, the other end is provided with the collet chuck be convenient to cutter and inserted, described cavity D is arranged between collet chuck and body, hydraulic oil is provided with in described cavity D, described pinching screw, pin, seal and burnishing-in ball are flexibly connected with the two ends of A inside, hole respectively, space is left in centre, and holding screw and steel ball are arranged on C end, hole.
Further, described body and collet chuck are seal welding, and pad is arranged on each end points of collet chuck.
Further, described body interior is provided with inclined hole.
Further, described hole A, hole B, hole C and cavity D are interconnected, and wherein said hole B is communicated with by the inclined hole on body with cavity D.
Further, described set screw is can move setting along the direction of axis line of body.
The utility model compared with prior art, it has following beneficial effect: hydraulic pressure handle of a knife of the present utility model, when coming into operation, set screw can move along the direction of axis line of body, play the effect regulating tool length, pin, seal, hole A seals by pinching screw, holding screw, hole C seals by steel ball, hole B seals by sealing screw, it is inner that hole A stayed by burnishing-in ball after completing burnishing-in effect to hole A, its extruded hole inwall improves hole surface roughness, increase substantially sealing property, collet chuck and body are Welding Structure, reliable sealed environment is provided for producing high pressure, revolve pinching screw inward and can promote pin, seal makes the volume of hydraulic oil reduce, pressure increases, collet chuck is caused to be out of shape, clamp-on tool, revolving pinching screw in the other direction can loosening cutter.The utility model is reasonable in design, and structure is simple, and hole wall good airproof performance, coupling mechanism force that burnishing-in is crossed are large, high pressure causes collet chuck homogeneous deformation ground clamp-on tool, cutter and handle of a knife axiality high, convenient when installing and change cutter, only need rotate pinching screw with spanner and can realize locking or loosening cutter.
