Apparatus for polishing aviation precision forging blade front trailing edge contour

Abstract

The invention provides an apparatus for polishing an aviation precision forging blade front trailing edge contour. With the apparatus, the problems that in the process of manually polishing a precision forging blade front trailing edge contour in the prior art, the production efficiency is low, the manner is not suitable for batch production, and manual polishing is difficult to control in qualityand stability. The apparatus for polishing the aviation precision forging blade front trailing edge contour comprises a machine case. An industrial robot arm, a material rack and a polishing wheel are installed on the lower part of the interior of the machine case respectively. A laser contour detection device is installed on the upper part of the interior of the machine case. A pair of calipersused for clamping a blade is installed at an actuating end of the industrial robot arm. The polishing wheel is driven by a driving device installed on the machine case to rotate. The laser contour detection device, the calipers and the driving device are connected with a computer of the industrial robot arm in an electronic control manner. The material rack is detachably installed in a drawer on the side of the machine case through a positioning assembly. The material rack comprises a bracket and a material plate. The material plate is detachably installed at the position of an opening in thetop of the bracket through a first positioning assembly. At least two profiling grooves are formed in the material plate.

Description

technical field [0001] The invention relates to the field of processing equipment for precise forging blades of aeroengines and gas turbines, in particular to equipment for polishing and grinding the front and rear edge profiles of aviation precision forging blades. Background technique [0002] Usually, the shape of the leading and trailing edge profile of precision-forged blades of aero-engines and gas turbines has a great influence on the aerodynamic performance of the engines. The traditional process is to use manual polishing to polish the shape of the front and rear edge contours to meet the requirements of the drawing after milling, but the production efficiency of manual polishing is low, which is not suitable for mass production, and the quality of manual polishing is as high as Stability is also difficult to control. Contents of the invention [0003] Aiming at the above-mentioned problems of low production efficiency in the manual polishing of the profile of th...
