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

[0001] The invention relates to the technical field of aero-engine thin-wall blade polishing, in particular to an automatic deviation-correcting mechanism for a polishing machine abrasive belt. Background technique

[0002] Thin-walled blades are the core and key parts of aero-engines. However, due to their complex shape, high requirements, difficult processing, and frequent failures, the processing and manufacturing of thin-walled blades has always been the focus and difficulty of engine manufacturing. one.

[0003] In order to develop and produce high-quality and efficient thin-walled blades of a new generation of aero-engines, and solve the problems of difficult control of the surface quality of manual polishing, low efficiency, and high labor intensity, the polishing machine plays a very important role, and its performance directly affects Efficiency of thin-walled blades. The deviation of the abrasive belt is the key to the quality of the polishing. Mo...

Embodiment Construction

[0014] Describe the present invention below in conjunction with specific embodiment:

[0015] The automatic deviation correction mechanism of the abrasive belt of the polishing machine in this embodiment includes an infrared sensor, a DC servo motor 1 , an eccentric wheel 2 , a connecting rod 3 , a worm gear transmission mechanism 4 and a deviation correction roller 5 . The infrared sensor, the DC servo motor 1 and the worm and gear transmission mechanism 4 are all fixed on the bottom plate 6 of the polishing machine.

[0016] Such as figure 1 As shown, when the polishing machine polishes the thin-walled blade, the deviation-correcting roller 5 is used as the driving wheel and the deviation-correcting wheel of the polishing abrasive belt. When the abrasive belt deviates, the infrared sensor detects that the abrasive belt deviates from the polishing wheel, and transmits the detected micro-displacement to the external controller. The external controller judges the positive and ...
