Abstract

The invention provides a clamping device and method for improving the machining quality of radial holes of airfoil parts, including a first component, a second component and a third component arranged concentrically from top to bottom in sequence, and the center of the third component is provided with a The target airfoil part passes through the positioning mandrel, and the two wings of the target airfoil part fit on the annular curved surface of the third component and the circumferential surface of the second component. The present invention uses the characteristics of poor structural rigidity and easy deformation of the open structure of the part to be processed, and the characteristics of thin and easy deformation of the two wing walls of the part to be processed, abandons the traditional six-point positioning processing method, and adopts over-positioning and micro-deformation clamping The method of processing not only solves the problem of parts being out of tolerance and scrapping after processing with poor rigidity, but also saves the clamping time through the ingenious matching of the opening pressure plate and the hexagon socket screw, which not only improves the processing quality of the parts, but also improves the processing efficiency. The processing cost is reduced, and the device is simple and economical to manufacture.

Description

technical field [0001] The invention belongs to the field of machinery, and in particular relates to a clamping device and method for improving the machining quality of radial holes of airfoil parts. Background technique [0002] In the field of mechanical equipment, airfoil parts with radial holes are widely used due to their compact structure and light weight. The material of this kind of parts mainly involves stainless steel and light metal materials. Its structural characteristics are that the shape of the parts is like the two wings of flying creatures. The thickness of the two wings is 3mm. One Φ2H11 through hole and two Φ5H7 (+0.012 0) through holes, the tip and bottom of the two wings are respectively surrounded by the arc Φ60H8 (+0.046 0) and the arc Φ71 with an arc of 35° and a height of 2.5mm round table. Among them, the verticality requirement of the hole Φ12H7 to the bottom surface of the circular table is not greater than Φ0.01mm, and the requirement of the p...
