The invention discloses a numerical control machine tool for dual-blade blind hole fixed depth machining. The numerical control machine tool comprises a machine tool body (1), a machine tool electrical cabinet (2), a numerical control panel (3), a clamping table top (4), a tailstock (5) and a dual-blade fixed depth machining device (9). The machine tool electrical cabinet (2) is arranged on one side of the machine tool body (1), the machine tool electrical cabinet (2) and the numerical control panel (3) are connected through a rotating rod (36), and the clamping table top (4) is arranged at the upper end of the machine tool body (1). The machine tool body (1) is provided with a rail table top (7), the rail table top (7) is provided with a rail (6), the tailstock (5) and the dual-blade fixed depth machining device (9) are arranged on the rail (6), and the tailstock (5) is locked through a bolt. According to the numerical control machine tool for dual-blade blind hole fixed depth machining, the blind hole depth can be guaranteed in the bending process of a gun barrel, machining precision is improved, machining and transporting difficulty is reduced, the machining efficiency is approximately doubled at the same time, the demand for large consumption is met, and meanwhile the numerical control machine tool has the advantages of being simple in structure and low in cost.

Description

technical field [0001] The invention belongs to the field of processing equipment, and relates to a double-cutter blind hole fixed-depth machining numerical control machine tool. Background technique [0002] Due to the deepening of oil production depth, the consumption of oil production perforating guns is increasing. At the same time, the deeper the depth of the underground or the pressure on the seabed, the more stringent the wall thickness requirements for perforating guns, resulting in blind holes. Depth requirements are also getting stricter. However, since the length of the pipe is more than 10 meters before processing, its straightness cannot be guaranteed, and the processing depth limited by the numerical control system for the curved pipe cannot fully guarantee the processing accuracy. The convex surface is often processed too deep, and the concave surface is often processed insufficiently. , such processing can only meet the processing accuracy with large dimensi...

Problems solved by technology

However, since the length of the pipe is more than 10 meters before processing, its straightness cannot be guaranteed, and the processing depth limited by the numerical control system for the curved pipe cannot fully guarantee the processing accuracy. The convex surface is often processed too deep, and the concave surface is often processed insufficiently. , such processing can only meet the processing accuracy with large dimensional tolerances. For higher accuracy requirements, it is necessary to require the straightness of the pipe to reach a certain standard.

This increases the difficulty in the processing and transportation of the barrel tube, but the straightness of the tube after transportation still cannot be fully guaranteed

[0003] At the same time, the processing efficiency of a tool for ordinary CNC machine tools is low, and it is difficult to meet the current production requirements
