Problems solved by technology

[0004] With the complexity of the processing target structure, it is necessary to drill vertical micro holes on the inner wall of the existing hole. When the diameter of the existing hole is small and the position of the hole to be drilled is deep in the existing hole, the total length of the drill Larger than the diameter of the existing hole, it cannot be installed in the existing through hole along the radial direction of the existing hole, so that it cannot be drilled

specific Embodiment

[0075] In this embodiment, the punching device provided by the device embodiment is used to punch holes in the existing holes of the workpiece shell, such as Figure 7 As shown, the workpiece shell is a hollow rotary body structure, the bottom diameter is Φ400-Φ800mm, and the height is 1000-1400mm. The shell is a metal and composite material suit shell. The existing hole is close to one end of the workpiece, which is a stepped through hole. The axis and the horizontal plane The included angle is 55°, the large diameter of the existing hole is 25mm, and the small diameter is 15mm. A vertical blind hole with a depth of 2mm and a diameter of Φ5.5mm is machined at point P of the large diameter section. The drilling methods include:

[0076] Fix the workpiece on the fixed plate 401, adjust the elevator 402 to turn the fixed plate 401 55°, so that the existing holes are placed horizontally;

[0077] like image 3 As shown, the positioning block 101 and the positioning cylinder 102 ar...

Abstract

The invention provides a drilling bit assembly, a drilling device and a drilling method and belongs to the technical field of processing. The drilling bit assembly comprises a drill bit, a drill rod,a transmission part and an installing part. The drill bit is fixedly connected with the installing part and is installed on the drill rod through the installing part. The drill bit is perpendicular tothe axis of the drill rod. The transmission part is used for enabling the installing part to rotate. According to the drilling bit assembly provided by the embodiment of the invention, the drill bitis perpendicular to the axial direction of the drill rod and is installed on a rotary head, and the extending direction of the drill rod is changed. When drilling is conducted in an existing hole, thedrill rod can extend into the existing hole in the axial direction of the existing hole, the installing part is driven by the transmission part to rotate, thus the drill bit is driven to drill in thedirection perpendicular to the axis of the drill rod, and the problems that the total length of the drill bit, the drill rod and the like is larger than the diameter of the existing hole, the drill bit and the drill rod cannot be installed in the existing through hole in the radial direction of the existing hole, and thus drilling cannot be achieved are solved.

Description

technical field [0001] The invention belongs to the field of processing technology, and its specific application relates to a processing technology for drilling vertical micro-holes on the inner wall of a radial oblique through hole on a casing. Background technique [0002] At present, the application of drilling technology has been very extensive, and with the gradual increase in scientific research and production tasks, it has become increasingly proficient and precise. [0003] Existing perforating drill bit assembly usually comprises drill bit, drill pipe, transmission part and drive part, and drill bit and drill pipe are installed coaxially, and when drilling, drill bit is placed on the position to be drilled, and drive part drives transmission part to drive drill pipe along vertical direction, so as to drive the drill bit to drill vertically along the axis of the drill rod at the position to be drilled. [0004] With the complexity of the processing target structure,...
