A kind of engraving machine tool holder
Technical field
The present invention relates to fixture, particularly relate to a kind of engraving machine tool holder.
Background technology
Current tobacco lining knurling rolls mostly use numerical controlled carving and Laser Processing two kinds of methods, but these two kinds have its significant limitation.The burr that the embossing of numerical controlled carving produces is difficult to process, material can only select 45 common steel, even if employing low hardness steel material, due to embossing interval little (0.2mm × 0.2mm or 0.3mm × 0.3mm or 0.4mm × 0.4mm), require that cutter is also very tiny, in process, point of a knife is easy to fracture.Repeatedly tool changing had both added cutter cost depletions and had too increased cost process time, and was difficult to ensure the front and back uniformity of reticulate pattern, affect working (machining) efficiency and was also difficult to guarantee product performance and customer demand, more cannot meet the demand of processing high-hardness material.Laser Processing uses all relative having superiority at burr with cutter, is widely used on less demanding low side embossed product.But cannot process for the steel to steel knurling rolls of high-end product as required in cigarette machine packaging, because the line tooth of steel to steel is gradient grid, laser cannot cut out the side of band angle.How can either process the knurling rolls of high-accuracy high rigidity, can improve again working (machining) efficiency and the service life of cutter work in-process, be a difficult problem urgently to be resolved hurrily.
Summary of the invention
The object of this invention is to provide a kind of engraving machine tool holder, solve the problem of existing digital-controlled carving machine easy breaking, difficult cutting when the die steel material that processing engraving hardness is high.
The technical scheme that the present invention adopts for its technical problem of solution is,
A kind of engraving machine tool holder, include fixed mechanism and aligning gear, fixed structure has the connecting ring be connected with main shaft, this connecting ring is equipped with mount pad, have the projection of installing graver in mount pad, aligning gear is positioned at below graver, has gathering sill in this aligning gear, drive graver to stretch in gathering sill by main shaft, the blade angle of graver is adjusted;
In connecting ring, there is locating hole, in this locating hole, be provided with tight fixed bolt, screwed in by tight fixed bolt and in locating hole, connecting ring is fixed on main shaft;
Connecting ring end is provided with thread segment, has the screwed hole matched with this thread segment in mount pad, is stretched in screwed hole be assemblied on connecting ring by mount pad by thread segment;
In projection, there is seam, projection is divided into two parts by this seam, there is in seam the cell body holding graver shank, the edge of a knife of graver stretches out from cell body, projection sidepiece is provided with through hole, this through hole is vertical with seam, is stretched in through hole and is engaged by projection two parts, make graver be fixed in projection by attachment screw;
Gathering sill is linear pattern, and its inwall is consistent with the edge of a knife shape of graver, and its opening portion has V-type notch.
The invention has the advantages that, during use, the attachment screw in projection can be unscrewed, graver is stretched in gathering sill and corrects, correction is tightened after completing, then Carving Machining is carried out, be convenient to the direction controlling the edge of a knife, this engraving machine tool holder combines the processing characteristic of lathe and planer, combine again the accuracy of numerical controlled carving, improve cutting-tool's used life, avoid product grid because of repeatedly tool changing produce uneven, the problem of burr is easily produced when decreasing engraving, make product more attractive in appearance handy, solve material hardness and carve the problem being difficult to carry out or cannot accurately ensure the quality of products greatly, the mould processed is not only attractive in appearance but also hardness is high, long service life.

Detailed description of the invention
The technological means realized to make the present invention, creation characteristic, reaching object and effect is easy to understand, below in conjunction with diagram and specific embodiment, setting forth the present invention further.
As shown in Figure 1, Figure 2, Figure 3 shows, the engraving machine tool holder that the present invention proposes includes fixed mechanism and aligning gear, fixed structure has the connecting ring 2 be connected with main shaft 1, this connecting ring 2 is equipped with mount pad 3, have the projection 5 of installing graver 4 in mount pad 3, aligning gear 6 is positioned at below graver 4, has gathering sill 7 in this aligning gear 6, drive graver 4 to stretch in gathering sill 7 by main shaft 1, the blade angle of graver 4 is adjusted;
There is in connecting ring 2 locating hole 8, in this locating hole 8, be provided with tight fixed bolt, screwed in by tight fixed bolt and in locating hole 8, connecting ring 2 is fixed on main shaft 1;
Connecting ring 2 end is provided with thread segment 9, has the screwed hole matched with this thread segment 9 in mount pad 3, is stretched in screwed hole be assemblied on connecting ring 2 by mount pad 3 by thread segment 9;
There is in projection 5 seam 10, projection 5 is divided into two parts by this seam 10, there is in seam 10 cell body 11 holding graver 4 shank, the edge of a knife of graver 4 stretches out from cell body 11, projection 5 sidepiece is provided with through hole 12, this through hole 12 is vertical with seam 10, is stretched in through hole 12 and is engaged by projection 5 two parts, make graver 4 be fixed in projection 5 by attachment screw;
Gathering sill 7 is linear pattern, and its inwall is consistent with the edge of a knife shape of graver 4, and its opening portion has V-type notch 13.
During use, the attachment screw in projection can be unscrewed, graver is stretched in gathering sill and corrects, correction is tightened after completing, then Carving Machining is carried out, be convenient to the direction controlling the edge of a knife, this engraving machine tool holder combines the processing characteristic of lathe and planer, combine again the accuracy of numerical controlled carving, improve cutting-tool's used life, avoid product grid because of repeatedly tool changing produce uneven, the problem of burr is easily produced when decreasing engraving, make product more attractive in appearance handy, solve material hardness and carve the problem being difficult to carry out or cannot accurately ensure the quality of products greatly, the mould processed is not only attractive in appearance but also hardness is high, long service life.
