Blade all can be used in a lot of plant equipment, and as various pump class, fan, steam turbine, the hydraulic turbine, aero-engine and screw etc., its blade profile part is the working portion of blade.Blade profile both on-plane surfaces of blade, also non-cylindrical, but irregular curved surface.Crudy (precision, hardness and the texture requirement etc.) important indicator such as operational efficiency, service life on equipment of blade surface has important impact.
Vane foil is processed by Digit Control Machine Tool, and the main shaft of Digit Control Machine Tool and multiple coordinates of workbench do linear moving interpolation simultaneously, makes cutter space tracking feed on request, completes corresponding complex-curved processing.In process, there will be to fall the phenomenon of cutter or lifts, affect the machining accuracy of blade surface.
And ultrasonic wave processing is carried out to metal surface can obtain low roughness value and high manufacturing accuracy, and have the advantages that efficiency is high, cost is low.The ultrasonic wave processing of metal surface is completed by ultrasonic cutter, different ultrasonic cutters can process difform surface, on the main shaft that ultrasonic cutter can be directly installed on corresponding lathe or knife rest, or be arranged on supersonic machining apparatus, complete under the drive of lathe supersonic machining apparatus and the ultrasonic wave of surface of workpiece is processed.Ultrasonic cutter also can as being arranged in the tool magazine of machining center or CNC milling machine other cutter, disclosed in Chinese patent literature CN102259271A " installation method of a kind of ultrasonic cutter on lathe ", equally with other cutter to use, ultrasonic wave processing is carried out to surface of the work.
But due to the complexity of spoon of blade, the thickness of blade is general all less, poor rigidity, add and be easy to man-hour produce distortion, existing ultrasonic wave processing cutting tool or device can not directly be processed blade surface expeditiously, also cannot ensure ultrasonic wave crudy.
Summary of the invention
The present invention is directed to the deficiency that existing blade exists in ultrasonic wave processing, provide a kind of and can ensure blade processing quality, prevent from being out of shape, blade ultrasonic metallic surface processing device that working (machining) efficiency is high.
Blade ultrasonic metallic surface processing device of the present invention, by the following technical solutions:
This device, comprise taper shank, the first ultrasonic cutter, the second ultrasonic cutter and travel mechanism, the large end of taper shank is provided with guide rail, and the first ultrasonic cutter and the second ultrasonic cutter are installed on guide rail, are connected with travel mechanism between the first ultrasonic cutter and the second ultrasonic cutter.
Two ends pedestal being positioned at guide rail are provided with guiding mechanism, and this guiding mechanism comprises adjusting seat and adjustment screw rod, and adjusting seat is fixed on pedestal, and adjustment screw rod is connected in adjusting seat.
Taper shank is provided with limited block between the first ultrasonic cutter and the second ultrasonic cutter, to ensure that two ultrasonic cutters can not contact when being worked into the edge of blade.
The present invention arranges two ultrasonic cutters, and connected by travel mechanism, two ultrasonic cutters can move simultaneously, distance between the two can be adjusted automatically by travel mechanism, and two cutters are relocatable form in finishing process, cancels each other to the external force that blade produces, blade does not affect by external force, well solve in the problem adding deformable blade in man-hour, ensure that ultrasonic wave processing is carried out in the best condition, improve the surface quality of blade.

Detailed description of the invention
As shown in drawings, blade ultrasonic metallic surface processing device of the present invention mainly comprises taper shank 1, guide rail 11, first ultrasonic cutter 6, second ultrasonic cutter 8 and cutter travel mechanism.The large end of taper shank 1 is connected on a pedestal 13, pedestal 13 is provided with guide rail 11.Being connected to by taper shank 1 on a pedestal 13, is for the ease of processing, and pedestal 13 and taper shank 1 also can as a whole (being referred to as taper shank).First ultrasonic cutter 6 and the second ultrasonic cutter 8 are arranged on guide rail 11 each via slide block 10, and the first ultrasonic cutter 6 and the second ultrasonic cutter 8 can move on guide rail 11.The two ends that pedestal 13 is positioned at guide rail 11 are provided with guiding mechanism, the effect of this guiding mechanism be when adjusting the distance between the first ultrasonic cutter 6 and the second ultrasonic cutter 8 when processing the blade of different-thickness and prevent from not working cutter from landing guide rail 11.This guiding mechanism comprises adjusting seat 12 and adjustment screw rod 14, adjusting seat 12 is fixed on pedestal 13, adjustment screw rod 14 is threaded connection in adjusting seat 12, moved it by rotation adjustment screw rod 14 and reach adjustment object, locked by locking nut 15 after adjusting, when ultrasonic cutter moves, the block 16 bottom it withstands on adjustment screw rod 14 end.Pedestal 13 is provided with this limited block 5 of limited block 5(between the first ultrasonic cutter 6 and the second ultrasonic cutter 8 can be as a whole, also two parts can be divided into, so that processing), the effect of limited block 5 ensures that two ultrasonic cutters can not contact when being worked into the edge of blade 7.First ultrasonic cutter 6 and the second ultrasonic cutter 8 can be arranged as shown in drawings at an angle, also can linearly be arranged symmetrically with.
Travel mechanism is provided with between first ultrasonic cutter 6 and the second ultrasonic cutter 8.Concrete structure is, the slide block of the first ultrasonic cutter 6 and the slide block of the second ultrasonic cutter 8 are installed the first connecting plate 4 and the second connecting plate 9 respectively, travel mechanism adopts cylinder 2, and cylinder 2 is arranged on the first connecting plate 4, and the piston 3 of cylinder 2 is connected with the second connecting plate 9.Travel mechanism also can adopt the structures such as hydraulic cylinder, spiral travel mechanism, electric rod.
The embody rule process of said apparatus is as described below:
By taper shank 1, whole device is arranged on the main shaft of the above CNC milling machine of four axles.By on the numerical control rotating platform of blade 7 clamping on CNC milling machine workbench, and blade 7 is between the first ultrasonic cutter 6 and the second ultrasonic cutter 8.Adjust the distance between the first ultrasonic cutter 6 and the second ultrasonic cutter 8 by travel mechanism, make two surface contact that both are relative with blade 7 respectively, and apply certain pressure in ultrasonic wave process.Blade 7 rotates with numerical control rotating platform and presses running orbit with CNC milling machine workbench and runs, and ultrasonic cutter is driven by the main shaft of CNC milling machine and moves up and down.The rotary motion of numerical control rotating platform, the horizontal movement of CNC milling machine workbench and moving up and down of CNC milling machine main shaft combine, and ultrasonic cutter is run by the space tracking required by blade surface, complete ultrasonic wave processing.Because two cutters are floating connections, therefore cancel each other to the external force that blade produces in process, blade does not affect by external force, and adding man-hour blade can not be out of shape.
Also can be arranged on the main shaft of plain-milling machine or boring machine by taper shank 1, carry out ultrasonic wave processing by two relative faces on the first ultrasonic cutter 6 and the second ultrasonic cutter 8 pairs of workpiece simultaneously.
The present invention is also applicable to the processing of other thin-walled parts.
