Finishing improvement method for turning surface quality of rectifier assembly matching part

Abstract

The invention discloses a finishing improvement method for the turning surface quality of a rectifier assembly matching part. The method comprises the following steps of step 1, pasting an adhesive tape to the part, not needing to be ground, of a rectifier part and then binding the adhesive tape pasting part by using a nylon rope; step 2, pouring grinding fluid prepared in proportion into a material box; step 3, clamping a lower edge plate on one side of the rectifier part through a finishing clamp, starting the material box to rotate in the clockwise or anticlockwise direction after the rectifier part is clamped, starting a pitching function and a head rotating function of a mechanical arm of finishing equipment again, rotating clockwise or anticlockwise firstly and then rotating anticlockwise or clockwise rotation, and completing finishing machining of the arc surface on one side of the rectifier part; step 4, carrying out finishing machining on the other side of the rectifier part after the rectifier part is subjected to surface changing and clamping, and repeating the step 3; and step 5, washing and blow-drying the rectifier part. According to the method, the problems that therectifier needs to be frequently repaired and the assembly progress is influenced due to blockage during assembly are prevented.

Description

technical field [0001] The invention belongs to the technical field of rectifier surface treatment, and in particular relates to a method for improving the surface quality of the turning surface of a rectifier assembly matching part. Background technique [0002] The structure of the upper and lower edge plates of the aero-engine rectifier is in the form of a segment designed according to the state of being assembled into the engine casing. Usually, the single-stage rectifier is designed as an eight-segment segment, which is assembled on two semicircular casings. To form a closed ring, after the rectifier and the casing are assembled into a semi-circular form, the lower edge plate generally needs to be assembled with two semi-circular annular sealing parts. Therefore, the arc shape of the upper and lower edge plates of the rectifier There are some surfaces in the structure that have the properties of assembly fit. Since the upper and lower edge plates of the rectifier are s...
