Arc surface drilling equipment

Abstract

The invention discloses arc surface drilling equipment, which comprises two flexible tracks. A movable framework is arranged on the flexible tracks; a vertical plate is mounted on the movable framework via a linear guide rail; the vertical plate is rotatably connected with a swing plate; and an electric main shaft is mounted on the swing plate. The electric main shaft is slidably connected with the swing plate via a hoop, and the swing plate is connected with a swing driving mechanism. The electric main shaft can move longitudinally, transversely and vertically on the drilling equipment, and can swing and rotate, so a drilling range of the electric main shaft is expanded, absorption positions of the flexible tracks on the surface of a workpiece are not needed to be frequently changed, theworking intensity is reduced, the working efficiency is improved, and the processing cost is lowered; meanwhile, the drilling equipment is more stable, and the drilling precision is improved.

Description

technical field [0001] The invention relates to a drilling device, in particular to a curved surface drilling device, which is mainly used for surface drilling of large workpieces with undulating surfaces, such as aircraft shell skins and the like. Background technique [0002] It is very troublesome to drill on the surface of a large workpiece with undulating surfaces. The existing drilling equipment structure has a flexible track. The flexible track includes a track plate, and through grooves are arranged longitudinally on the track plate. The middle part forms gear teeth. A suction cup is connected below the track plate through a connecting column. The flexible track is equipped with a moving frame, and two rows of walking wheels are installed below the moving frame to match the two sides of the track plate, so that the moving frame can move smoothly on the flexible track. The moving power of the moving frame is that a motor is installed on the moving frame, and the out...

AI Technical Summary

Problems solved by technology

The drilling equipment with this structure has a single row of flexible rails, and the electric spindle on the mobile frame can only rotate itself and move along the flexible rails with the mobile frame, so that the drilling is strictly limited. Frequent replacement of the position of the flexible rail adsorption is time-consuming, labor-intensive, and high processing cost. At the same time, the stability of the mobile frame itself is poor, and there will be obvious errors in the drilling position.
