Abstract

The invention discloses an inner cooling drilling, reaming and countersinking integrated tool and a system comprising the tool. The tool comprises a tool handle and a tool bit. The tool bit part is provided with a drilling part, a reaming part and a countersinking part. An inner cooling way is arranged in the tool handle and the tool bit part. The part, located at the tool bit part, of the inner cooling way is spirally distributed in the spiral direction of a spiral groove of the tool bit part or/and the direction opposite to the spiral direction. The system further comprises a cooling device.The cooling device comprises a liquid storage barrel, a cooling pipe and a ring sleeve sleeving the tool handle part. An annular cooling liquid channel is formed by the inner circle of the ring sleeve and the outer circle of the tool handle and communicates with a radial inner cooling way, the ring sleeve is provided with a liquid inlet, and the liquid storage barrel is connected with the liquidinlet in the ring sleeve through the cooling pipe.

Description

technical field [0001] The invention relates to the technical field of cutting tools, in particular to an internally cooled drilling, reaming and spot-sinking integrated cutting tool and a system including the cutting tool. Background technique [0002] In mechanical processing production, ordinary tools can only be used in one processing technology, such as drilling cutters, milling cutters, reamers and countersinks. In the processing of some important parts, the step-by-step processing of tool replacement is likely to affect the processing accuracy. Especially in the laminated structure composed of aluminum alloy, titanium alloy and composite materials in the field of aerospace, due to the different material properties in the hole making process, it is easy to produce deviations during processing, and when the tool is processing high hardness structural layers, it will A large amount of heat is generated, the position of the drill bit is deep, and it is difficult for the ...
