Description
Technical field
The utility model is related to machining technique field, more particularly, to a kind of drill jig and drilling machine.
Background technology
Drill jig is the holding appliance being processed to workpiece on drilling machine.
Hole machined is carried out to workpiece on general drilling machine, more with following features：
(1) cutter rigidity in itself is poor
The hole of the hole processed on drilling machine mostly small-medium size, its operation content is nothing more than brill, expansion, hinge, ream or tapping
Deng processing, so, tool diameter is often smaller, and axial dimension is larger, and the rigidity of cutter is poor.
(2) multi-blade is asymmetric, easily causes the Form and position error in hole.
The aperture knife tools, mostly multiple-cutting-edge tool such as brill, expansion, hinge, when blade distribution is asymmetric, or edge length is unequal,
The foozle in processed hole can be caused, in particular by common Twist Drill, two side tools caused by hand grinding drill bit
Sword it is asymmetric, easily cause to be processed the hole position skew in hole, the bending of aperture increases and axially bored line and crooked, have a strong impact on hole
Shape, positional precision.
(3) when common spiral bit pulls out of hole, hole position precision extreme difference.
Need to use drill bushing to improve the precision of drilling when therefore drilling.
In the prior art, common fluted drill axial dimension is big, and poor structure rigidity adds the chisel edge that drill core structure is formed,
Destruction centering, moves apex point unstable, often causes larger hole position error during cobalt is played.In single-piece, small lot batch manufacture
In, often to lean on operative employee that manual synchronizing control hole position precision is constantly carried out in trip-out process, and it is efficiently raw in high-volume
In product, then the strict guiding by the improvement and fixture of edge structure to cutter is needed to solve.
Inventor has found, when hole of the diameter less than 1mm is processed, using existing drill bushing substantially less than expected
Effect, the error in the hole for being got out or larger.Hole that drill bushing processes precision in itself and hole are directly affected due to drill bushing
Position precision, those skilled in the art have found that using existing drill jig cannot be the small drill bushing of diameter, and special jewel
Set is oriented to.Therefore, how a kind of drill jig is provided, can be accurately oriented to for the less drill bit of diameter, be those skilled in the art
Problem demanding prompt solution.
Based on this, the utility model provides a kind of drill jig to solve above-mentioned technical problem.

Embodiment two
The drilling machine that the present embodiment is provided, the technical scheme described by embodiment one falls within the embodiment, embodiment
One technical scheme having been described above is not repeated description.
Specifically, in the present embodiment there is provided a kind of drilling machine, including the drill jig described in main body and embodiment one,
The main shaft of the drilling machine main body is connected with the connector.
The drilling machine that the utility model is provided, has used the drill jig, can give full play of the drill jig
All advantages, it is high in machining efficiency.High-precision micro hole can be especially processed, micro hole in the prior art is solved and is difficult to
The technical barrier of processing.
Based on this, the utility model has the advantages that the aperture for being capable of machining high-precision than original technology.
One of purposes of the drilling machine that the utility model is provided is manufacture ring mould, can produce and be difficult on the market at present
The small orifice ring mould of manufacture.The pellet that small orifice ring mould is used for required for producing small fish shrimp.
The drill bit that manufacture small-bore ring mould is used is very thin, and such stiffness of twist drill is low, yielding.Once drill bit occurs
Deformation, not only the life-span of drill bit lose, and the ring calligraphy or painting model body that processes aperture easily occur inconsistent.Ring mould exists in particle
Used on feed ring mould machine, there are tens thousand of apertures thereon.
Granulator structure mainly including motor, transmission mechanism, rotor, ring mould, pressure roller, scraper group, cutting knife etc., wherein two
Individual pressure roller and ring mould constitute nip region, by rotating against for ring mould and pressure roller, by powder raw material extrusion forming.Its process
For：Uniformly sent between two pressure rollers and ring mould by scraper group after modulated, be molded through the nib of ring mould, extruded outward,
The strip feed of above-mentioned extrusion is cut into the length of needs through cutting knife, the pellet of shaping is finally made.
Therefore, during Fodder making, nib thereon is subject to very big extruding force to ring mould, if ring calligraphy or painting model body occurs
Aperture is inconsistent, is very easy to the phenomenon for causing it fracture occur, fracture, and causes ring mould to fail.Even if ring mould is not reaching to break
Failure is split, the aperture of ring calligraphy or painting model body is inconsistent, and the little particle feed produced does not reach quality standard yet, causes feed former material
The waste of material.
If production small-bore ring mould, drill bit is just thinner, because the phenomenon for easily producing fracture, fractureing when handing over；
Finally it should be noted that：Various embodiments above is only used to illustrate the technical solution of the utility model, rather than it is limited
System；Although being described in detail to the utility model with reference to foregoing embodiments, one of ordinary skill in the art should
Understand：It can still modify to the technical scheme described in foregoing embodiments, or to which part or whole
Technical characteristic carries out equivalent；And these modifications or replacement, the essence of appropriate technical solution is departed from this practicality newly
The scope of each embodiment technical scheme of type.
