Embodiment 1

[0036] see Figure 1-8 As shown, a processing technology applied to the top cover of a spacecraft specifically includes the following steps:

[0037] Step 1. Place the top cover above the suction cup 301, turn on the vacuum pump 304, and generate a negative pressure inside the suction cup 301 through the air duct 305. The bottom of the top cover is in contact with the rubber pad 303 provided on the inner wall of the suction cup 301. The surface is in contact with the bottom of the top cover, so that the top cover is adsorbed inside the suction cup 301;

[0038] Step 2: The second linear motor 208 slides on the surface of the second linear slide rail 207, so that the positioning frame 201 is approached to one side of the top cover, and then the two second servo electric cylinders 202 drive the two positioning plates 203 to the top cover. The upper and lower surfaces are clamped, and the drive shaft of the third servo electric cylinder 204 pushes the limit plate 205 to limit th...

Abstract

The invention relates to the technical field of part machining, in particular to a machining technology applied to a spacecraft top cover, and the machining technology comprises the steps that the top cover is clamped in a vacuum suction cup mode, positioning is conducted in cooperation with a positioning mechanism, and solid waste cleaning is conducted through a solid waste cleaning mechanism. Then, a milling cutter arranged in the movable frame moves downwards to the top of the top cover, the milling cutter rotates in the movable frame with the X-axis linear axis and the Z-axis linear axis as axes, meanwhile, the milling cutter moves in the movable frame with the Y-axis linear axis and the Z-axis linear axis, and five-axis linkage is achieved under control of a numerical control system; in the machining process, the milling cutter is always perpendicular to the machined face of the top cover, milling machining on the top cover is completed in a physical milling mode, compared with a chemical milling mode, the physical milling operation procedure is simple, the machining efficiency is high, meanwhile, the milling cost is lower than that of chemical milling, and solid waste generated in the machining process is easy to treat.

Description

technical field [0001] The invention relates to the technical field of parts processing, in particular to a processing technology applied to the top cover of a spacecraft. Background technique [0002] The top cover of spacecraft generally uses thin-walled skin parts, and chemical milling has been used in the processing of such parts. The chemical milling process requires processes such as spraying, scribing, chemical milling and degumming. The solid waste generated in the chemical milling process is troublesome to deal with, the processing efficiency is low, the processing cost is high, and the economic benefit is poor. [0003] In view of the above technical problems, a solution is proposed. SUMMARY OF THE INVENTION [0004] (1) Technical problems solved [0005] Aiming at the deficiencies of the prior art, the present invention provides a processing technology applied to the top cover of a spacecraft, which solves the problems of complicated procedures, troublesome so...
