Embodiment Construction

[0022] Specific embodiments of the present invention will be described in detail in combination with technical solutions and drawings.

[0023] like figure 1 As shown, the central axis of the drilling template 4 is placed horizontally, and one end of the mandrel 6 is inserted into the center of the chute 17 of the drilling template 4, and the other end is fixed by a bracket 8. The first drilling unit 2 and the second drilling unit 3 are respectively fixedly connected to the turntable 5, the center hole of the turntable 5 is coaxial with the center hole of the drilling template 4, and is penetrated by the mandrel 6, and the turntable 5 can be wound around the mandrel mandrel 6. Free rotation, no matter how the drilling template 4 rotates around its own axis, the first drilling unit 2 and the second drilling unit 3 are always in a free-sagging state under the action of their own gravity. One group of pads 9 are fixed on the flange 18 of the drilling template 4, and the purpose ...

Abstract

The invention provides a device which has a simple structure and can be used for automatically drilling a large-size compound cylinder in batches along a radial direction aiming at the problems of difficulty in tool setting and low drilling efficiency in the process of drilling the large-size compound cylinder along the radial direction. A processing mode of processing from inner to outer is adopted in the drilling device, thereby avoiding the fiber tearing and layering on the inner wall of a cylinder made of compound materials. By using a double-power head for drilling, first and second rows of holes can be processed at the same time. In order to change a drilling position, a drilling unit is rotated without moving the large-size compound cylinder, thereby widening the processing range. And meanwhile, a drilling device bracket is designed for storing and mounting the drilling device and avoiding the rubbing between the drilling device and the inner wall of the cylinder.

Description

technical field [0001] The invention relates to a device for automatically drilling holes in the radial direction of a large composite cylinder. Background technique [0002] In the field of aviation manufacturing, there is a cylindrical part made of carbon fiber composite material, referred to as a composite cylinder. A metal end frame is set at the end of the composite cylinder, and the metal end frame and the cylinder body of the composite cylinder are connected in the radial direction of the cylinder wall by bolts, so it is necessary to process a round hole in the radial direction on the end frame and the cylinder body of the composite cylinder . The diameter and length of the composite cylinder are more than several meters, so there are hundreds of round holes processed. [0003] At present, the drilling device in mechanical manufacturing is mainly a drilling machine. During the drilling process of an ordinary drilling machine, the drilling tool or fitter is used to m...
