Abstract
The embodiment of the utility model discloses lathe deep hole bores, including cutting head and cutter arbor, the cutting head install in cutter arbor head one end just leaves a space between the two, the cutter arbor is installed in the lathe saddle, realizes the auto -feed along with the lathe saddle motion, the cutter arbor is inside hollow through -hole, cutter arbor connection of after section supplies the coolant apparatus, cut overhead first cutting edge (4), second cutting edge (5) of being provided with, be provided with one third chip dividing groove (6) on first cutting edge (4), be provided with first chip dividing groove (7), second chip dividing groove (8) on second cutting edge (5), chip dividing groove (6) set up in the middle part of first cutting edge (4), first chip dividing groove (7) and second chip dividing groove (8) trisection second cutting edge (5). Adopt the utility model discloses cut firstly smaller, the auto -feed can be realized at the head of cutter arbor, pole dress to cutting head dress on the knife rest.
Description
Technical field
The utility model relates to drill bit field, particularly relates to a kind of lathe deep and bores.
Background technology
Original is use lengthening drill bit mode:
Be limited by the degree of depth of lengthening drill bit boring, holing on lathe exactly at one, is that the handle after manually shaking tail stock is holed, the iron filings but also not easily exit of not only requiring great effort.Manually, in boring procedure, need constantly to add water, once water can not enter on drill lip, drill bit is easy to burn, and causes cost high.
Utility model content
The utility model embodiment technical problem to be solved is, provide a kind of cutting head smaller, cutting head is contained in the head of knife bar, and bar to be contained on knife rest and can to bore the lathe deep of auto-feed.
For solving the problems of the technologies described above, the utility model embodiment provides a kind of lathe deep and bores, and comprises cutting head and knife bar, it is characterized in that: described cutting head is installed on described knife rod head one end and leaves a space between the two; Described knife bar is installed on lathe saddle, realizes auto-feed with lathe saddle motion; Described knife bar is inside the through hole of hollow; Described knife bar afterbody connects for coolant apparatus; Described cutting head is provided with the first cutting edge (4), the second cutting edge (5); Described first cutting edge (4) is provided with the 3rd chip dividing groove (6); Described second cutting edge (5) is provided with the first chip dividing groove (7), the second chip dividing groove (8); Described chip dividing groove (6) is arranged at the middle part of described first cutting edge (4); Second cutting edge (5) described in described first chip dividing groove (7) and the second chip dividing groove (8) trisection.
Preferably, the anchor ring that described 3rd chip dividing groove (6) can sweep is positioned in the middle of described first chip dividing groove (7) and the inswept anchor ring of the second chip dividing groove (8), and three does not interfere with each other.
Preferably, the angle between described first cutting edge (4) and described second cutting edge (5) is 120 °.
Preferably, the vertical section diameter of described knife bar is less than the vertical section diameter of described cutting head.
Preferably, described knife bar is steel pipe.
Preferably, described cutting head and described knife bar are wholely set.
Implement the utility model embodiment, tool has the following advantages:
Cutting head is smaller, relatively good mill, and cutting head is contained in the head of bar, and bar is contained on knife rest can auto-feed, and knife bar is that steel pipe is made, and iron filings are that the water that added by steel pipe or cooling fluid are taken out of.Bore diameter 40mm's, also can get into about 2 meters.The course of work can auto-feed, and labour intensity is large.
Accompanying drawing explanation
Fig. 1 is the utility model example structure schematic diagram;
Fig. 2 is the partial enlarged drawing of A in the empty frame of the utility model embodiment Fig. 1.
Detailed description of the invention
For making the purpose of this utility model, technical scheme and advantage clearly, below in conjunction with accompanying drawing, the utility model is described in further detail.
As depicted in figs. 1 and 2, a kind of lathe deep of the utility model example bores, and comprise cutting head 1 and knife bar 2, cutting head 1 is installed on knife bar 2 head one end and leaves a space between the two; Knife bar 2 is installed on lathe saddle 3, moves and realize auto-feed with lathe saddle 3; Knife bar 2 is inside the through hole of hollow; Knife bar 2 afterbody connects for coolant apparatus; Cutting head is provided with the first cutting edge 4, second cutting edge 5; First cutting edge 4 is provided with the 3rd chip dividing groove 6; Second cutting edge 5 is provided with the first chip dividing groove 7, second chip dividing groove 8; 3rd chip dividing groove 6 is arranged at the middle part of the first cutting edge 4; First chip dividing groove 7 and the second chip dividing groove 8 trisection second cutting edge 5.
Preferably, the anchor ring that the 3rd chip dividing groove 6 can sweep is positioned in the middle of the first chip dividing groove 7 and the inswept anchor ring of the second chip dividing groove 8, and three does not interfere with each other.
Preferably, the angle between the first cutting edge 4 and the second cutting edge 5 is 120 °.
Preferably, the vertical section diameter of knife bar 2 is less than the vertical section diameter of cutting head 1.
Preferably, knife bar 2 is steel pipes.
Preferably, cutting head 1 and knife bar 2 are wholely set.
The utility model embodiment cutting head is smaller, relatively good mill, cutting head is contained in the head of bar, and bar is contained on knife rest can auto-feed, knife bar is that steel pipe is made, and the water added by steel pipe or the space of cooling fluid between cutting head and steel pipe head are flowed out thus take iron filings out of.Bore diameter 40mm's, also can get into about 2 meters.The course of work can auto-feed, and labour intensity is large.
Above disclosedly be only a kind of preferred embodiment of the utility model, certainly can not limit the interest field of the utility model with this, therefore according to the equivalent variations that the utility model claim is done, still belong to the scope that the utility model is contained.
