Abstract

The invention relates to a drilling machine for machining inner blind holes and in particular relates to a numerical-control drilling machine for machining an inner blind hole of an oil-production perforation gun tube body, and the drilling machine provided by the invention is used for solving the problem in the prior art fails that the inner blind hole of a perforation gun tube with a small inside diameter can not be directly machined. The rotation of a drill bit which is arranged on a cutter head mechanism is achieved by the transmission of a chain which is driven by a drive motor which is arranged on a chain transmission mechanism. The longitudinal feeding operation is achieved by the engagement of a feeding gear and a toothed rack which are driven by a feeding motor which is arranged on a longitudinal feeding mechanism through a feeding worm and a feeding worm wheel. The division of a chuck is achieved by the transmission of a division worm wheel and a division worm which are driven by a division motor which is arranged on a chuck division mechanism. The clamping of the chuck is achieved by driving a chuck clamping sleeve on a chuck clamping mechanism through a chuck clamping motor which is arranged on the chuck clamping mechanism. A numerical control device controls the transmission motor, the feeding motor, the division motor, the chuck clamping motor and a hydraulic control motor which is arranged on a hydraulic control system respectively. An oil inlet is connected with an oil supply pipe which is arranged on the hydraulic control system through an oil pipe. The numerical-control drilling machine provided by the invention is applied to machining the inner blind holes.

Description

technical field [0001] The invention relates to a drilling machine for processing inner blind holes. Background technique [0002] When oil drilling is completed, it is necessary to open the oil layer with a perforating gun. At present, perforation is based on the principle of high-efficiency energy-concentrating blasting. The cable is used to send the perforating gun to the part of the oil layer casing to be perforated, and the electric detonator is used to detonate the perforating bullet. The bullet is a high-efficiency gunpowder pressed into a dense, energy-gathering cone, covered with a copper skin. Gunpowder deflagration along the center of the conical surface instantly shoots through the oil layer casing wall and cement layer at a high speed of 8,000 meters per second and a high temperature jet flow above 2,000°C, and then penetrates 300 to 500 mm in the formation. Therefore, it is necessary to The inner blind hole is processed on the wall of the perforating gun barr...
