Description
Technical field
The present invention relates to a kind of tool changing device, particularly a kind of open type integral leaf dish tool changing device.
Background technology
With reference to Fig. 4, document " Chinese utility model patent of Granted publication CN202106080U " discloses a kind of device of changing facing cutter, this device comprises cutter spindle 1, milling cutter 3, pack into the centre of positioning sleeve 5 and floating bushing 6 of milling cutter 3 penetrates cutter spindle 1, the male cone (strobilus masculinus) of cutter spindle 1 cooperates with internal taper hole on the positioning sleeve 5 with locking nut 2 lockings, and the other end of cutter spindle 1 screws with accurate nut 4 and by floating bushing 6 compression milling cutters 3.This device milling cutter connects with cutter spindle can not bear the high pulling torque milling, and upper and lower side adopts locking nut and accurate nut, and axial locking power is inadequate, and tool changing is about 8min/ time average time.
Open type integral leaf dish is the important component part of modern aeroengine, obtains comparatively extensive use in the production of modern aeroengine with in making.Compare with wheel hub assembling leaf dish structure with traditional blade, blisk has saved the tenon and the tongue-and-groove that connect, has simplified the aero-engine structure, has the thrust-weight ratio of raising, improves aeroperformance, Extending Rotor service life and improve the advantage such as reliability.
In order to improve the working (machining) efficiency of open type integral leaf dish, the employing dish mills+inserts and mill+complex machining process of side milling, can remove the allowance of blank 90%.And in 90% allowance, dish mills the allowance that processing can be removed 60%-80% approximately, and remaining 20%-40% is undertaken by inserting to mill.This shows that the processing characteristics that dish mills plays vital effect to the working (machining) efficiency of blisk.
Because the blank of open type integral leaf dish mostly is titanium alloy, high-temperature alloy material, hardness is higher, belongs to difficult-to-machine material.The metal removal rate of typical case's titanium alloy only is most of ordinary steels or stainless about 25%.Therefore, process tool is had higher requirement.The performance of cutter has improved greatly by increasing matrix density, design the special shape of tool, adopt accurate cutting edge grinding technique and developing new coating technology with the ways such as heat in metal cutting that the control tool interface produces in cutting tool manufacturer.Although the milling cutter performance of titanium alloy is greatly improved before comparing, in Milling Process, a key property of titanium alloy is exactly the heat conductivity extreme difference.Because high strength and the low-thermal conductivity of titanium alloy, add and can produce high heat in metal cutting man-hour, can not reach 1200 ° of C if do not add control.Heat is not to absorb along with the cutting discharge or by workpiece, but be gathered on the cutting edge, so high heat will shorten cutter life greatly, for guaranteeing quality and the precision of converted products, must be in process frequent tool changing, high-frequency tool changing action like this certainly will reduce the working (machining) efficiency of blisk.Therefore studying a kind of easy and simple to handle, time saving and energy saving dish mills the power Rapid knife exchanging mechanism, and to improving the blisk working (machining) efficiency, the development that promotes China's aerospace industry is significant.
Summary of the invention
