Description
Technical field
The present invention relates to one kind combination broad, and in particular to a kind of row's pan reaming processing long of big L/D ratio is used
Combination broad, belong to cutting-tool engineering field.
Background technology
When aircraft Product Assembly is processed, the processing of pan is commonly encountered, especially big L/D ratio（Processing hole length and diameter
The ratio between）Pan.As type aircraft is for the accurate to dimension of pan, the axiality in hole and surface quality requirements
More and more higher, and processing length with hole also increasing, that is, finished after several part combinations when assembling, because
, in the case where aircaft configuration complexity, locus are limited, cutter from side feed, and can only cause the length of cutter to be turned over for this
Times, now according to wryneck drilling row single hole processing, then cannot ensure the axiality requirement of all well.In addition, between run into hole
Away from it is less when, traditional reaming way is processed using several one group of fixed tools that length is different, wherein mistake
Not only there is many technical barriers in cold and hot working, detection process in cutter long, and due to using solid tool, therefore work as
It is whole that cutter is accomplished by cancel during tool wear, cause the cost of charp tool high, economic loss is big.
The content of the invention
A kind of length it is an object of the invention to provide big L/D ratio arranges the combination broad of pan reaming processing,
While ensureing dimensional accuracy, axiality requirement, the surface roughness requirements in hole, its long service life is effectively extended, and
Reduce cost.
Technical scheme：Combination broad, including tool bit part I, pilot bushing II, extension rod III and connection
The part of bar IV 4, wherein tool bit part I are followed successively by preceding guiding, cutting edge, whorl brace rod from front to back vertically, in leading
Lead and be provided with wrench position, circular cone locating surface is provided with the junction of cutting edge and whorl brace rod；The front end of extension rod III
Face center is sequentially provided with the threaded connection hole of the circular cone location hole and whorl brace rod cooperation coordinated with circular cone locating surface,
The outer surface of the body front end of extension rod III is provided with wrench position, and whorl brace rod is provided with the rear end of the body of extension rod III,
The body of extension rod III is provided with circular cone locating surface with the junction of whorl brace rod；The front end face center of connecting rod IV is sequentially provided with
The threaded connection hole that the circular cone location hole and whorl brace rod coordinated with circular cone locating surface coordinate, in the body front end of connecting rod IV
Outer surface be provided with wrench position, be provided with pintle hook lock coupling part in the rear end of the body of connecting rod IV, pintle hook lock coupling part is fixed
On automatic drill riveter；Pilot bushing II is enclosed within extension rod III and coordinates with the clearance-type of extension rod III essence.
Beneficial effects of the present invention：The present invention design combination broad, not only can arbitrarily, flexibly change cutter
Length, and the guiding with former and later two directions in processing, pilot bushing and extension rod are coordinated using clearance-type essence, led
Can flexibly be moved on extension rod to bushing, be directed to bushing and be placed in when in the suitable machined hole for finishing, then after playing
The effect of guiding, is designed to suitable knife-tooth structure and geometric parameter by cutting edge in addition, ensure that processed row long
The high request and surface quality requirements of axiality before and after pan；The combination broad of present invention design, can in dismounting
Dismounted with the space in suitable auricle, each part has wrench position, therefore ensure that the convenience of dismounting；Cutter
Life-span essentially consists in tool wear, and the combination broad of present invention design only needs to change tool bit part in tool wear,
Pilot bushing, extension rod and connecting rod can be reused, thus gang tool economy and practicality considerably beyond entirety
Cutter, greatlys save cost.
Brief description of the drawings
Fig. 1 is overall structure diagram of the invention.
Specific embodiment
As shown in figure 1, combination broad, including tool bit part I, pilot bushing II, extension rod III and connecting rod IV 4
Part, wherein tool bit part I guide 1, cutting edge 3, whorl brace rod 6 before being followed successively by from front to back vertically, in preceding guiding 1
Wrench position 2 is provided with, circular cone locating surface 4 is provided with the junction of cutting edge 3 and whorl brace rod 6；Before extension rod III
The threaded connection of the circular cone location hole 5 and cooperation of whorl brace rod 6 coordinated with circular cone locating surface 4 is sequentially provided with end face center
Hole 7, wrench position 8 is provided with the outer surface of the body front end of extension rod III, and being provided with screw thread in the rear end of the body of extension rod III connects
Extension bar 11, circular cone locating surface 9 is provided with the junction of the body of extension rod III and whorl brace rod 11；In the front end face of connecting rod IV
The threaded connection hole 12 of the circular cone location hole 10 and cooperation of whorl brace rod 11 coordinated with circular cone locating surface 9 is sequentially provided with the heart,
Wrench position 13 is provided with the outer surface of the body front end of connecting rod IV, pintle hook lock connecting portion is provided with the rear end of the body of connecting rod IV
Divide 14, pintle hook lock coupling part 14 is fixed on automatic drill riveter；Pilot bushing II be enclosed within extension rod III and with the gap of extension rod III
