Embodiment Construction

[0021] The present invention will be further elaborated below in conjunction with the accompanying drawings.

[0022] as attached Figures 1 to 3 Shown, a kind of composite deep hole processing device, comprises BTA deep hole drilling tool 1, gun drill deep hole drilling tool 2, composite deep hole processing device also includes for fixedly installing BTA deep hole drilling tool 1 and gun drill The supporting plate 3 of the deep hole drilling tool 2, and the spiral chip removal machine 4 fixedly installed on the supporting plate 3. The supporting plate 3 is assembled on the machine bed body, and the supporting plate 3 is locked by hydraulic pressure. The BTA deep hole drilling tool 1 and the gun drill deep hole drilling tool 2 are fixed on the supporting plate 3 by screws and conical pins. The BTA deep hole drilling tool 1 and the gun drill deep hole drilling tool 2 are arranged side by side above the supporting plate 3 , and both are in contact with each other. The spiral...

Abstract

The invention relates to a complex deep hole machining device. The complex deep hole machining device comprises a BTA (benzotriazole) deep hole drilling tool and a gun-drilling deep hole drilling tool, and further comprises a supporting plate and a spiral chip discharger, wherein the BTA deep hole drilling tool comprises an oil feeder box, a connecting rod, a first guide sleeve, a BTA drill bit, an oil feeder piston and an oil feeder cylinder; the gun-drilling deep hole drilling tool comprises a guide frame box, a guide frame cylinder, a gun-drilling piston, a second guide sleeve, a gun-drilling drill bit, a chip feeding opening and a chip discharging opening. The BTA deep hole drilling tool and the gun-drilling deep hole drilling tool are mounted on the same supporting plate, so that a BTA drilling way and a gun-drilling way coexist and the drilling range is enlarged; the BTA deep hole drilling tool and the gun-drilling deep hole drilling tool are added with rotating components respectively, so that a workpiece tightening and rotating function is achieved and a turning torque of a conventional hydraulic cylinder at the bottom of the supporting plate is reduced.

Description

technical field [0001] The invention relates to a tooling facility, in particular to a compound deep hole processing device. Background technique [0002] When the length-to-diameter ratio of the drilled hole is greater than 8 and the drilled hole diameter is below 35mm, 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 drilling length-to-diameter ratio is greater than 5 and the drilling diameter is above 16mm, BTA deep hole drilling tools are usually used for deep hole processing. When drilling, the cutting oil enters the c...
