Abstract
The utility model provides a kind of composite boring cutters of numerical control borer, including blade, cutter holder, housing screw, cutter hub and blade screw；Fixed symmetrical is equipped with totally four cutter holders on the outside of one end of the cutter hub, and a blade is fixedly installed on cutter holder；Also there are two housing screw and two blade screws for fixed symmetrical installation in the outside of the cutter hub.Unilateral coarse-fine boring boring cutter structural reform is the coarse-fine boring boring cutter body of symmetrical double-pole by the present apparatus, symmetrical stress when making knife bar chip, it reduces because being shaken caused by asymmetric stress, angle mount cutter holder is changed to embedded, cutter holder fixation is stronger, do not have to beat table adjustment size when more allowing blade replacement, blade exchange is quick, and blade is changed to rectangular by diamond shape, two chip angles can be increased, blade cost of use is reduced, production efficiency is improved, aperture is checked by 100%, it is reduced to 10%, vibration when processing obviously weakens, and blade service life increases, and the later period, which spends, to be reduced.
Description
Technical field
The utility model belongs to boring machine accessory technical field, more specifically, in particular to a kind of numerical control borer it is compound
Boring cutter.
Background technique
Boring machine is divided into the types such as horizontal boring machine, floor-type milling & boring machine, diamond fine boring machine and jig boring machine.Horizontal boring machine: application is most
A kind of most wide boring machine of more, performance is suitable for jobbing work and repair workshop.Floor-type milling & boring machine: feature is that workpiece is fixed
On landing platform, it is suitable for processing dimension and the biggish workpiece of weight, is used for heavy-duty machinery manufactory.
Based on above-mentioned, the inventors discovered that, stress is asymmetric when the knife bar chip of present boring cutter, thus be easy to cause compared with
Strong vibration, production efficiency is lower, and blade exchange is inconvenient, and blade service life is shorter, causes more cost.
Utility model content
The purpose of this utility model is to provide a kind of composite boring cutters of numerical control borer, to solve to mention in above-mentioned background technique
Out the problem of.
To achieve the above object, the utility model provides the following technical solutions:
A kind of composite boring cutters of numerical control borer, including blade, cutter holder, housing screw, cutter hub and blade screw；The cutter hub
One end on the outside of fixed symmetrical totally four cutter holders are installed, and a blade is fixedly installed on cutter holder；Outside the cutter hub
Also there are two housing screw and two blade screws for fixed symmetrical installation for side.
Further, the cutter hub is the coarse-fine boring boring cutter body of symmetrical double-pole.
Further, the blade is square structure, and cutter holder is installation by adhering when installing blade.
Compared with prior art, the utility model has the following beneficial effects:
Unilateral coarse-fine boring boring cutter structural reform is the coarse-fine boring boring cutter body of symmetrical double-pole by the present apparatus, when making knife bar chip symmetrically by
Power is reduced because shaking caused by asymmetric stress, angle mount cutter holder is changed to embedded, and cutter holder fixation is stronger, when more allowing blade replacement
Without beating table adjustment size, blade exchange is quick, and blade is changed to rectangular by diamond shape, can increase by two chip angles, reduce blade
Cost of use improves production efficiency, and aperture is checked by 100%, is reduced to 10%, and vibration when processing obviously weakens, and blade makes
Increased with the service life, the later period, which spends, to be reduced.
Detailed description of the invention
Fig. 1 is the schematic view of the front view of the utility model.
Fig. 2 is the overlooking structure diagram of the utility model.
In figure, the corresponding relationship of component names and accompanying drawing number are as follows:
Blade -1；Cutter holder -2；Housing screw -3；Cutter hub -4；Blade screw -5.
Specific embodiment
The embodiments of the present invention is described in further detail with reference to the accompanying drawings and examples.Following embodiment
For illustrating the utility model, but cannot be used to limit the scope of the utility model.
In the description of the present invention, unless otherwise indicated, the meaning of " plurality " is two or more；Term
The orientation of the instructions such as "upper", "lower", "left", "right", "inner", "outside", " front end ", " rear end ", " head ", " tail portion " or position are closed
System is to be based on the orientation or positional relationship shown in the drawings, and is merely for convenience of describing the present invention and simplifying the description, rather than
The device or element of indication or suggestion meaning must have a particular orientation, be constructed and operated in a specific orientation, therefore cannot
It is construed as a limitation of the present invention.In addition, term " first ", " second ", " third " etc. are used for description purposes only, and cannot
It is interpreted as indication or suggestion relative importance.
In the description of the present invention, it should be noted that unless otherwise clearly defined and limited, term " phase
Even ", " connection " shall be understood in a broad sense, for example, it may be being fixedly connected, may be a detachable connection, or be integrally connected；It can
To be mechanical connection, it is also possible to be electrically connected；It can be directly connected, it can also be indirectly connected through an intermediary.For this
For the those of ordinary skill in field, the concrete meaning of above-mentioned term in the present invention can be understood with concrete condition.
Embodiment:
As shown in attached drawing 1 to attached drawing 2:
The utility model provides a kind of composite boring cutters of numerical control borer, including blade 1, cutter holder 2, housing screw 3, cutter hub 4
With blade screw 5；Fixed symmetrical is equipped with totally four cutter holders 2 on the outside of one end of cutter hub 4, and is fixedly installed with one on cutter holder 2
A blade 1；Also there are two housing screw 3 and two blade screws 5 for fixed symmetrical installation in the outside of cutter hub 4.
Wherein, the cutter hub 4 is the coarse-fine boring boring cutter body of symmetrical double-pole, and symmetrical stress when making knife bar chip is reduced because not right
Claim to shake caused by stress.
Wherein, the blade 1 is square structure, and cutter holder 2 is installation by adhering when installing blade 1, and the fixation of cutter holder 2 is more firm
Gu not having to play table when more allowing blade replacement 1 and adjusting size, blade 1 replaced fast, and blade 1 is changed to rectangular by diamond shape, can increase by two
Chip angle reduces by 1 cost of use of blade, improves production efficiency.
The specifically used mode and effect of the present embodiment:
In the utility model, blade 1 there are four fixed symmetrical settings, postwelding can be directly disposable on the cutter hub 4 of the present apparatus
Four holes are processed, and can guarantee four hole concentricities in 0.4mm, unilateral coarse-fine boring boring cutter structural reform is symmetric double by roughness 1.6
The coarse-fine boring boring cutter body of knife, symmetrical stress when making knife bar chip, reduces because shaking caused by asymmetric stress, angle mount cutter holder 2 is changed
To be embedded, the fixation of cutter holder 2 is stronger, does not have to when more allowing blade replacement 1 to play table and adjusts size, and blade 1 is replaced fast, and blade 1 is by water chestnut
Shape is changed to rectangular, can increase by two chip angles, reduce by 1 cost of use of blade, improve production efficiency, and aperture is checked by 100%,
It is reduced to 10%, vibration when processing obviously weakens, and blade service life increases, and the later period, which spends, to be reduced.
The embodiments of the present invention are given for the purpose of illustration and description, and are not exhaustively or to incite somebody to action
