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.

Embodiment Construction

[0017] Such as figure 1 , 2 , Shown in 3 and 4: two rows of flexible tracks are arranged, and the flexible tracks include a track plate 1, and two rows of connecting columns 5 are arranged below the track plate 1, and are fixedly connected by nuts between the connecting columns 5 and the track plate 1. A suction cup 4 is connected to the lower end of each pair of connecting columns 5 . Through grooves 2 are arranged on the track plate 1, and gear teeth 3 are formed between adjacent through grooves 2, and the through grooves 2 and the gear teeth 3 form a rack structure. The above-mentioned flexible track is a prior art and will not be described in detail.

[0018] Two rows of flexible rails are provided with a frame 6, and the frame 6 is welded and manufactured by section steel. Both sides of the track plate 1 in each row of flexible tracks are equipped with road wheels 11, that is, the road wheels 11 can roll along the sides of the track plate 1. Walking wheel 11 is instal...

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 an arc 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 holes on the surface of large workpieces with ups and downs. The existing drilling equipment structure is to have a flexible track. The flexible track includes a track plate. There are through grooves arranged longitudinally on the track plate. The intermediate portion forms the gear teeth. A suction cup is connected below the track plate through a connecting column. The flexible track is equipped with a mobile frame, and two rows of traveling wheels are installed under the mobile frame to match the two sides of the track plate, so that the mobile frame can move smoothly on the flexible track. The moving power of the mobile frame is that a motor is installed on the mobi...
