Abstract

The invention discloses a method for protecting a seat positioning hole before reducing noise, comprising the following steps of: firstly, forming a positioning hole with the same size and shape as a seat positioning hole at the center of a protective board; secondly, aligning the positioning hole of the protective board to the seat positioning hole on the side wall of a vehicle body; and directly drawing a protective area of the seat positioning hole along the shape of a protecting tool and protecting by using an adhesive tape. By using the protecting tool for the seat positioning hole before reducing noise and spraying paint, the seat positioning hole can be positioned and drawn, the size of the seat positioning hole can be quickly and accurately drawn and the seat positioning hole can be protected by using the adhesive tape. The invention is quick, simple and convenient for operation, greatly shortens the work time and improves the production efficiency.

Description

technical field [0001] The invention relates to a protection method for seat positioning holes before noise reduction treatment. Background technique [0002] The seat positioning hole is used for the installation and positioning of the seat in the car, because the surface of the seat positioning hole belongs to the assembly surface, and according to the technical requirements, the surface of the seat positioning hole is not sprayed with noise-reducing paint. Each train has more than 800 seat positioning holes on the side wall of the car body. Because the size of each seat positioning hole is the same, when performing protection before spraying the noise-reducing paint, take the center of the positioning hole as the measurement base point to measure, and then draw the upper and lower horizontal lines, left and right vertical lines; the area within the intersection of the horizontal and vertical lines is the seat Protect the area before spraying the noise-reducing paint on t...
