Abstract
The invention provides an automatic deviation rectifying mechanism for an abrasive belt of a polishing machine. The polishing condition of the abrasive belt is detected in real time by using a photoelectric sensor; when the abrasive belt deviates, micrometric displacement of deviation is transferred by the photoelectric sensor to a controller, a pulse signal sent by the controller is transferred to a direct current servo motor, an eccentric wheel is driven by the direct current servo motor to rotate, a connecting rod is driven by the eccentric wheel to swing, and then, a swing shaft is driven to rotate to enable a worm gear and worm mechanism to work and realize the linear motion of a worm and a deviation rectifying roller on the worm, so that the deviation rectification of the abrasive belt is realized. The mechanism is simple in structure, easy to realize and capable of realizing automatic deviation rectification in the thin-wall blade polishing process, eliminating the surface quality problem brought by the deviation of the abrasive belt, ensuring the stability of the surface quality of a blade and also improving the polishing effect of the blade.
Description
Technical field
The present invention relates to aero-engine thin wall vane polishing technology field, specifically is a kind of polishing machine abrasive band automatic deviation correction mechanism.
Background technology
Thin wall vane is an aero-engine core and crucial part the most, but because it is complex-shaped, requires highly, and difficulty of processing is big, and is the multiple part of fault, and therefore, the processing and manufacturing of thin wall vane all the time is one of the emphasis made of engine and difficult point.
High-quality for aero-engine thin wall vane of new generation, efficiently develop and produce; Solve manual polished surface difficult quality control, inefficiency, the difficult problem that labour intensity is big; Polishing machine has played important effect, and the quality of its performance directly has influence on the efficient of thin wall vane.And the abrasive band sideslip is the key point that influences quality of finish, and the sander of domestic production mostly adopts two-axle interlocking, the structure that the plane is killed off, and diaxon is middle a little more than two ends; Make the abrasive band middle stressed big, alleviate the abrasive band sideslip, but this structure is irrational in actual production; The abrasive band when idle running maybe be for a long time sideslip not, in case work owing to narrowed down by the sanding plank; Length and position are not complete ideals, thereby the abrasive band is stressed just inhomogeneous, make the abrasive band produce sideslip.
Summary of the invention
The technical problem that solves
The technical problem that the present invention solves is to utilize the abrasive band deviation correction mechanism to realize the abrasive band correction, avoids the influence of abrasive band sideslip to aero-engine blisk and blade surface quality, to improve the polishing precision of blisk and blade.
Technical scheme
Technical scheme of the present invention is:
Said a kind of polishing machine abrasive band automatic deviation correction mechanism is characterized in that: comprise infrared sensor, DC servo motor, eccentric wheel, connecting rod, Worm and worm-wheel gearing and correction running roller; Said infrared sensor, DC servo motor and Worm and worm-wheel gearing all are fixed on the polishing machine base plate; Said correction running roller is coaxial to be enclosed within on the worm screw of Worm and worm-wheel gearing, and connects through bearing, and the correction running roller can freely be rotated on worm screw; Infrared sensor detects polishing machine abrasive band sideslip situation, and offset signals is passed to peripheral control unit; Said DC servo motor is controlled by peripheral control unit, DC servo motor output shaft and coaxial connection of eccentric wheel one end, and the DC servo motor output shaft drives eccentric wheel and rotates; The said eccentric wheel other end is connected with connecting rod one end is eccentric, when eccentric wheel rotates, and the drivening rod swing, the connecting rod swing plane is vertical with the eccentric wheel axis; The connecting rod other end is fixed with swinging axle, and the swinging axle axis normal drives swinging axle and rotates in the connecting rod swing plane during connecting rod swing; Said swinging axle is fixedly connected with the worm gear of Worm and worm-wheel gearing is coaxial.
Beneficial effect
The present invention adopts photoelectric sensor to detect the abrasive band polishing situation in real time, and when finding the abrasive band sideslip, photoelectric sensor passes to controller with sideslip micrometric displacement amount; Controller sends pulse signal and passes to DC servo motor, and DC servo motor drives eccentric wheel and rotates, the swing of eccentric wheel drivening rod; And then the drive swinging axle rotates; Make worm-and-wheel gear work, realize worm screw and the rectilinear motion of the running roller of upward rectifying a deviation, thereby realize the correction in abrasive band.This mechanism structure simply is easy to realize, has realized the automation correction in the thin wall vane polishing process, has eliminated because the surface quality problems that the abrasive band sideslip brings makes the surface quality of blade stable, simultaneously, has improved the polishing effect of blade.

The specific embodiment
Below in conjunction with specific embodiment the present invention is described:
Polishing machine abrasive band automatic deviation correction mechanism in the present embodiment comprises infrared sensor, DC servo motor 1, eccentric wheel 2, connecting rod 3, Worm and worm-wheel gearing 4 and correction running roller 5.Said infrared sensor, DC servo motor 1 and Worm and worm-wheel gearing 4 all are fixed on the polishing machine base plate 6.
As shown in Figure 1, when polishing machine polished thin wall vane, correction running roller 5 was as the drive and correction wheel in polishing abrasive band.When sideslip appears in the abrasive band; Infrared sensor detects the abrasive band and departs from polishing wheel; And detected micrometric displacement passed to peripheral control unit; Peripheral control unit carries out positive and negative to running deviation value and displacement is judged, again pulse signal is passed to DC servo motor 1, begins to drive deviation correction mechanism behind the DC servo motor 1 received pulse signal.
Deviation correction mechanism is made up of eccentric wheel 2, connecting rod 3, Worm and worm-wheel gearing 4 and correction running roller 5, and eccentric wheel one end is fixedly connected with the DC servo motor output shaft is coaxial, and the DC servo motor output shaft drives eccentric wheel and rotates together.The eccentric wheel other end is connected through connecting axle is eccentric with connecting rod one end, when eccentric wheel rotates, and the swing of connecting axle drivening rod, the connecting rod swing plane is vertical with the eccentric wheel axis.The connecting rod other end is fixed with swinging axle, and the swinging axle axis normal drives swinging axle and rotates in the connecting rod swing plane during connecting rod swing.Said swinging axle is fixedly connected with the worm gear of Worm and worm-wheel gearing is coaxial, when swinging axle rotates, and worm gear drives worm screw rectilinear motion.Said correction running roller is coaxial to be enclosed within on the worm screw of Worm and worm-wheel gearing; And be connected through bearing with worm screw, the correction running roller can freely be rotated, on worm screw when worm screw receives the worm-gear driven rectilinear motion; The correction running roller is realized the correction to the abrasive band also synchronously along self axial-movement.
