The specific embodiment
With reference to Fig. 2.Polishing machine deviation correction mechanism of the present invention comprises deflection correction roller 8, correction axle 9, correction axle oscillation center 10, worm screw 11, deviation-rectifying bracket 12 and casing 13.Deflection correction roller 8 is fixed on deviation-rectifying bracket 12, deviation-rectifying bracket 12 is fixed on casing 13, one end of casing 13 is for supporting worm screw 11, the other end of casing 13 is fixing by will rectify a deviation spring stop 7 of trip bolt 6, correction spring 5 is between casing 13 and correction spring stop 7, and wear trip bolt 6, can be around 9 rotations of correction axle in deflection correction roller 8.Worm screw 11 converts the rotation of horizontal direction the both direction swing of correction axle 9 along correction axle oscillation center 10 to.
The present invention adopts the actuator of worm couple as deviation correction mechanism, and while clockwise rotating worm screw 11, worm screw 11 advances, extruding correction axle 9, the spring 5 of compression correction simultaneously.While needing oppositely to adjust correction wheel, reversion worm screw 11, correction spring 5 applies opposite force on correction axle 9, promotes correction axle 9 and swings along correction axle oscillation center 10, thereby realize the swing of correction wheel on both direction.Worm couple and correction axle oscillation center 10 are installed on casing 13, and casing 13 is fixed on gripper shoe 1.
All structures all are fixed on gripper shoe 1, and cylinder 2 applies a tensile force to abrasive band, and abrasive band is close on deflection correction roller 8.In polishing process, when the outside sideslip in abrasive band, for making abrasive band, get back to initial position, with running roller, overlap, the worm screw 11 that should advance, worm screw 11 applies a power to correction axle 9, the spring 5 of compression correction simultaneously, correction axle 9 swings along correction axle oscillation center 10, thereby drives the swing of deflection correction roller 8.When the inside sideslip in abrasive band, abrasive band is crossed and is close on deflection correction roller 8, not only affects the service life of abrasive band and correction wheel, and polishing effect is also had a negative impact.Now, worm screw 11 should be rotated counterclockwise and retreat, correction spring 5 imposes on 9 one pressure of correction axle, deflection correction roller 8 is shunk inwards, thereby reduce the tensile force in abrasive band.
Because numerical control polishing running deviation value in abrasive band in polishing process is less, only need be finely tuned abrasive band, so this numerical control polishing deviation correcting device is manually correction.While applying this deviation correction mechanism, the abrasive band of at first polishing being used clings on deflection correction roller 8, and abrasive band is preferably in the interlude position of deflection correction roller 8.When the startup lathe carries out abrasive band polishing, should guarantee that the abrasive band tensile force is suitable, adjust the pretightning force in abrasive bands by cylinder 2, and make worm screw 11 in suitable position.Can manual fine-tuning worm screw 11 when sideslip occurs when move in abrasive band on deflection correction roller 8, make abrasive band on deflection correction roller 8 in optimal location.
Apply above-mentioned numerical control polishing deviation correction mechanism, blade of aviation engine is carried out to numerical control polishing, greatly shortened polishing time, effectively improved the polishing effect of blade.
