Scribing platform for chemical-milling real samples

Abstract

The invention belongs to the technical field of process equipment, and provides a scribing platform for chemical-milling real samples. A support base is of a frame structure, a positioning plate is arranged on two top cross beams of the support base, the upper surface of the positioning plate is provided with a closed-loop scribing track groove, the scribing track groove is internally provided with a sliding wheel with a through hole in the middle, and the through hole of the sliding wheel is internally provided with a scribing needle; two parallel transverse sliding rails are arranged at twobottom cross beams of the support base, and each transverse sliding rail is provided with a plurality of transverse sliding blocks; the transverse sliding blocks of the two parallel transverse slidingrails correspond to one another in an arrangement sequence, and a longitudinal sliding rail is arranged between every two corresponding transverse sliding blocks on different transverse sliding rails10; each longitudinal sliding rail is provided with two longitudinal sliding blocks, each longitudinal sliding block is provided with a jacking rod sleeve, and each jacking rod sleeve is provided with a jacking rod. The scribing platform for the chemical-milling real samples is simple in structure, low in cost and simple and convenient in scribing operation and can be used for scribing chemical-milling real samples with different curvatures, the scribing efficiency and precision can be improved, and the scribing cost can be reduced.

Description

technical field [0001] The invention relates to a scribing table, in particular to a workbench for scribing lines of chemical milling real samples, which belongs to the technical field of process equipment. Background technique [0002] Some parts on the aircraft have milling areas for weight reduction. These milling areas are usually processed by chemical corrosion. During processing, protective glue is first applied to the surface of the parts, and then there is a margin on the chemical milling model. The opening of the milling area to carve off the film, and then put the parts into the corrosion solution for chemical corrosion processing. The actual chemical milling sample is the processing basis for manufacturing the chemical milling forming sample. The actual chemical milling sample has the margin markings of the milling area. These marking lines are drawn by the five-axis CNC machine tool with a stylus. The milled sample is placed on the mold tire and fixed with a nyl...

Problems solved by technology

The actual chemical milling sample is the processing basis for manufacturing the chemical milling forming sample. The actual chemical milling sample has the margin markings of the milling area. These marking lines are drawn by the five-axis CNC machine tool with a stylus. Place the milled sample on the mold tire and fix it with a nylon belt, then carry out CNC programming according to the margin on the three-dimensional digital model, and draw a line on the chemical milled sample, because the nylon belt cannot completely fix the chemical milled sample , the actual chemical milling sample will move during the scribing process, which will lead to the problem of the deviation of the scribing line of the chemical milling sample, and because the NC programming and CNC machine tool scribing efficiency is low, and the CNC machine tool is expensive, it will also lead to chemical The problem of long scribing cycle and high scribing cost of milling samples will affect the processing accuracy, efficiency and processing cost of chemical milling samples
