Abstract

The invention relates to a composite deep hole machine tool. The composite deep hole machine tool comprises a machine body, a drilling tool, a driving mechanism which is arranged on the machine body and used for driving the drilling tool to drill a hole, a guiding mechanism, a chippings recovery mechanism which is arranged on the machine body and a cooling filtering mechanism, wherein the drilling tool comprises a BTA drilling rod and a gun drill, which are arranged in parallel, the guiding mechanism comprises a pre-tightening device, oil feeding devices and a guiding frame, the pre-tightening device is arranged on the front part of the machine body in a way of sliding in the longitudinal direction and used for pre-tightening a workpiece, the oil feeding devices are arranged side by side on the machine tool in the lateral direction, the front part of the BTA drilling rod is arranged in the oil feeding device in a penetrating manner, the rear end of the BTA drilling rod is installed on the driving mechanism, the front part of the gun drill is arranged in the guiding frame in a penetrating manner, and the rear end part of the gun drill is installed on the driving mechanism. The BTA drilling rod and the gun drill are arranged on one machine body, so that a machining way of coexistence of the BTA and gun drill is realized, and the drilling range is enlarged; the pre-tightening device is used for pre-tightening the workpiece, so that the deviation of the oil feeding device when in movement can be reduced.

Description

technical field [0001] The invention relates to a compound deep hole machine tool. Background technique [0002] When the length-to-diameter ratio of the drilled hole is greater than 8 and the drilled hole diameter is below φ35mm, gun drilling deep hole drilling tools are usually used for deep hole processing. When drilling, the cutting oil enters the inner hole of the gun drill tool through the inner hole of the tool drive unit, and then reaches the cutting area. The cutting oil carries chips and is discharged from the gun drill guide frame through the processed hole wall and the V-shaped groove of the tool. After the gun drill bit enters the workpiece, it uses its self-guiding function to complete deep hole drilling. When the length-to-diameter ratio of the drilled hole is greater than 5 and the drilled hole diameter is above φ16mm, BTA deep hole drilling tools are usually used for deep hole processing. When drilling, the cutting oil enters the cutting area through the o...
