A method for improving the turning surface quality of rectifier assembly mating parts

Abstract

A method for improving the turning surface quality of rectifier assembly and matching parts, comprising the following steps: step 1, attaching adhesive tape to the parts of the rectifier parts that do not need to be ground, and then using nylon rope to bind the adhesive tape parts; step 2, proportionally Pour the prepared grinding fluid into the material box; step 3, clamp the lower edge plate on one side of the rectifier part with the lightening fixture, start the material box to rotate clockwise or counterclockwise after the rectifier part is clamped, and turn on the lightening machine again The pitch function of the mechanical arm of the equipment and the head rotation function, first rotate clockwise or counterclockwise, and then counterclockwise or clockwise to complete the finishing process of the arc surface on one side of the rectifier part; step 4, change the surface of the rectifier part After clamping, carry out the finishing process on the other side, repeat step 3; step 5, rinse and dry the rectifier parts. To prevent the stagnation of rectifiers during assembly, which often requires additional repairs and affects the progress of assembly.

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...

Problems solved by technology

[0003] The purpose of the present invention is to provide a method for improving the surface quality of the turning surface of the assembly and matching parts of the rectifier, which adopts the work of improving the surface quality by using the finishing method, and makes the assembly and matching surface texture under the condition that the geometric accuracy is not affected. The shape is changed, and at the same time, the scales and roughness of the entire surface are thoroughly cleaned to achieve a deep level of cleanliness, solve the unfavorable phenomena in the assembly of rectifiers, and solve the inherent properties of the turning arc surface
