Description
Technical field
Add the present invention relates to rebecca antenna house machine and mounting technology field, in particular to the variable separation of a kind of guide post
Formula broad.
Background technique
Rebecca antenna house machine, which installs additional, applies the threaded connectors such as a large amount of screw with during, this is just needed multiple
Drilling on condensation material cover or relevant metalwork.For the hole being relatively large in diameter, to avoid composite material cover from being layered, usually will
Drilling is divided into system just hole and whole two, hole step.In general, first hole does not have specific size, can be 2~φ of φ 6,
Specific size can determine depending on the practical function in first hole.First hole can be drilled according to the hole bit line on cover surface, can also be in machine adding type
It is produced when face by numerically-controlled machine tool；And when the drill bit using whole pore diameter size carries out manual reaming, there will be reaming front and back
Hole the poor problem of concentricity.
In the rebecca antenna house assembling process of different model, it is identical to be frequently present of whole hole size, but first Kong great little
Different situations.At this moment, the common approach is that and guide post diameter identical using whole bore dia is different (or without leading in production
Column) drill bit carry out reaming.This method need to use the cutter of a variety of different sizes and need to replace clamping back and forth, costly and time consuming
It is long.
Summary of the invention
The purpose of the present invention: a kind of separate type broad that guide post is variable is provided, it is intended to solve to fly in different model
In machine radome assembling process, need to drill several whole hole aperture sizes are identical and hole that first hole aperture size is different, because
This needs to complete drilling task respectively using the cutter of different size, and manufacturing cost increases and the problem of low efficiency.
Technical solution of the present invention:
A kind of separate type broad that guide post is variable, including reaming bit and variable guide post, the reaming bit packet
Include gripping section and cutting edge section, the cutting edge section bottom is provided with threaded hole, the variable guide post include thread spindle and
Guide section, the reaming bit and variable guide post are cooperatively connected by thread spindle and threaded hole.
The guide section diameter is bigger than thread spindle.
The reaming bit is made of hard alloy, high-speed steel, nickel-manganese.
The variable guide post is made of hard alloy.
The guide section bottom is conical chamfering section.
The thread rotary orientation of the thread spindle and the direction of rotation of reaming bit are opposite.
The guide section diameter is no more than processed first hole aperture.
The angle of the conical chamfering section is 90 ° -120 °.
Beneficial effects of the present invention: it proposes a kind of separate type broad that guide post is variable, efficiently solves common drilling
In the process, the problem of the concentricity difference between first hole and whole hole reduces production cost, energy using a variety of drilling cutters by reducing
Enough obtain good quality and benifit and economic benefit.

Fig. 1 is schematic structural diagram of the device of the invention；
Fig. 2 is apparatus of the present invention structure sectional view；
Fig. 3 is reamer bit structure schematic diagram；
Fig. 4 is variable guide pillar structure schematic diagram；
It is identified in figure: 1, reaming bit, 2, variable guide post, 3, gripping section, 4, cutting edge section, 5, threaded hole, 6, thread spindle,
7, guide section.
Specific embodiment
The present invention is further introduced with reference to the accompanying drawing, a kind of separate type expansion that guide post is variable of the present invention
Spot facing cutter, entire cutter include reaming bit 1 and variable guide post 2, and as shown in Figure 1, 2, reaming bit 1 is mainly used for existing first
Hole carries out ream operation, and the reaming bit 1 includes gripping section 3 and cutting edge section 4, and gripping section 3 is for realizing electricity/pneumatic drill
Clamping, to realize the integral-rotation drilling campaign of reaming bit 1, cutting edge section 4 can be realized in rotational movement process to being added
Work part is cut, and 4 bottom of cutting edge section is provided with threaded hole 5, the variable guide post 2 include thread spindle 6 and
Guide section 7, by the way that guide section 7 is processed as different diameters and integral installation into threaded hole 5, can be realized to it is different just
Hole carries out guiding reaming.
The reaming bit 1 and variable guide post 2 is cooperatively connected by thread spindle 6 and threaded hole 5, to can be changed guide post 2
Installation fixation can be carried out on reaming bit 1.
7 diameter of guide section is bigger than thread spindle 6, and 7 diameter of guide section is no more than processed first hole aperture.
The reaming bit 1 is made of hard alloy, high-speed steel, nickel-manganese.Guide post 2 be can be changed by hard alloy system
At.
7 bottom of guide section is conical chamfering section, and the angle of conical chamfering section is 90 ° -120 °.
The thread rotary orientation of the thread spindle 6 is opposite with the direction of rotation of reaming bit 1.
Concrete operation step of the invention are as follows:
(1) reaming bit 1 be threadedly coupled being integrally formed with variable guide post 2；
(2) use electricity/pneumatic drill by 1 firm grip of reaming bit；
(3) guide section 7 of variable guide post 2 is inserted into just hole；
(4) it opens electricity/pneumatic drill switch and carries out reaming.
If to carry out reaming to the first hole of different pore size to the whole hole of same apertures, corresponding guide post need to only be selected to carry out
Replacement.Compared to direct replacement, clamping drill bit, the variable guide post 2 of directly replacement threaded connection is time-consuming shorter, more efficient.
If to carry out reaming to the first hole of same apertures to the whole hole of different pore size, the guide post need to be only respectively installed to
On the reaming bit of different size.Compared to using the drill bit of different size to carry out reaming respectively, this method is effectively reduced
Entire manufacturing cost, during the present invention efficiently solves common drilling, the problem of the concentricity difference between first hole and whole hole passes through
Reducing reduces production cost using a variety of drilling cutters, can obtain good quality and benifit and economic benefit.
