Detailed description of the invention
In order to make object of the present invention, technical scheme and advantage clearly understand, below in conjunction with drawings and Examples, the present invention is further elaborated.Should be appreciated that specific embodiment described herein only in order to explain the present invention, be not intended to limit the present invention.
Please refer to Fig. 1-Fig. 2, in a kind of detailed description of the invention, borer mounting structure provided by the present invention, comprises the outer sleeve 2 and the interior inner sleeve 3 inserting in outer sleeve 2 that are installed on cutter tower; Outer sleeve 2 is provided with cooling fluid entrance 7; Inner sleeve 3 is provided with water channel 10, and the arrival end of water channel 10 is communicated with cooling fluid entrance 7, and the port of export penetrates into the boring cutter end face (boring cutter end face refers to the end face that boring cutter inserts) of inner sleeve 3; Boring cutter inserts in inner sleeve 3 by described boring cutter end face.
Above-mentioned example is by designing the structure of inner sleeve 3 and outer sleeve 2, and inner sleeve 3 is provided with water channel 10, boring cutter is installed on inner sleeve 3, during boring cutter work, cooling fluid can directly be ejected in machining hole by the port of export of water channel 10, thus make boring cutter and work-piece cools cooling, prevent the blade tipping of boring cutter and fracture, the service life of boring cutter can be extended; Meanwhile, owing to there being washing away of cooling fluid, the variations in temperature of part is less, can ensure the stability of processing dimension.
Cooling fluid entrance 7 is positioned at the sidewall of outer sleeve 2.Cooling fluid entrance 7 is located at sidewall, can prevents cooling fluid pipeline and boring cutter, workpiece from interfering, be convenient to the processing of workpiece.The cold also entrance 7 that goes also can be arranged at the end face of outer sleeve 2.
The through hole of the side sidewall of the usual through outer sleeve 2 of cooling fluid entrance 7, the cooling fluid pipeline of cutter tower inserts through hole.This structure is convenient to processing, and convenient for assembly.
Usual through hole is provided with internal thread near one end of the outer wall of outer sleeve 2, and one end that cooling fluid pipeline inserts through hole is provided with external screw thread, and external thread bolt connection is in internal thread.Be threaded connection, make the connection of cooling fluid pipeline and cooling fluid entrance 7 more reliable, thus ensure that cooling fluid supply is sufficient.Through hole can be also unthreaded hole, and cooling fluid pipeline is directly plugged in unthreaded hole.
Through hole is arranged along the radial direction of outer sleeve 2 usually, convenient processing, and ensures the shortest path of cooling fluid.The axis of certain through hole can be also an angle with the axis of outer sleeve 2.
Through hole is shoulder hole, and its one end diameter near the inner arm of outer sleeve 2 is less.To facilitate being communicated with of cooling fluid entrance 7 and water channel 10.
Cooling fluid entrance 7 also can be the pipeline arranged along the axial screw of outer sleeve 2.
Water channel 10 is an angle with the axis of inner sleeve 3, and the one end stretching to boring cutter end face is close to axis.By the water channel 10 be obliquely installed, cooling fluid can be made to the central-injection of boring cutter, thus ensure that cooling fluid more easily enters machining hole, improve the cooling effect of boring cutter and workpiece further.Water channel 10 and axis also can be arranged in parallel, or bending is arranged.
Be circumferentially with annular groove along inner sleeve 3 between inner sleeve 3 and outer sleeve 2, annular groove is communicated with cooling fluid entrance 7, arrival end respectively.By increasing annular groove, being communicated with of cooling fluid entrance 7 and arrival end can be facilitated, convenient processing and assembling; Cooling fluid is introduced into annular groove simultaneously, is entering arrival end, ensures the abundance supply of cooling fluid further.
Annular groove can be located at outer sleeve 2, also can be provided with inner sleeve 3, or the two all arranges annular groove, and preferably the two all arranges annular groove, so that the circulation of processing and guarantee cooling fluid.As shown in Figure 1, annular groove comprises the overcoat groove 8 of the inwall being located at outer sleeve 2 and is located at the inner sleeve groove 9 of inner sleeve 3, and the notch of overcoat groove 8 is relative with the notch of inner sleeve groove 9; Cooling fluid entrance 7 is communicated with overcoat groove 8, and arrival end is communicated with inner sleeve groove 9.
