Description
Technical field
The utility model relates to machining tool, is specifically related to a kind of reamer of deep hole processing.
Background technology
In a lot of plant equipment, there is a kind of casing part, referring to Fig. 1, this casing part 6 comprises casing body 60, be axially arranged with two upper deep holes 61 that are parallel to each other and lower deep hole 62 at casing body 60, the depth of parallelism between described upper deep hole 61 and lower deep hole 62 is had relatively high expectations, and vertical range is each other larger and the degree of depth itself is larger.The upper deep hole 61 of this casing part 6 and lower deep hole 62 generally adopt boring cutter to carry out preliminary boring on boring machine or machining center, leave surplus, finally on boring machine, adopt reamer machine-shaping.Because the depth of parallelism between upper deep hole 61 and the lower deep hole 62 of this casing part 6 is had relatively high expectations, vertical range is each other larger and the degree of depth itself is larger.Thereby the knife bar of the reamer of employing is just long, and the knife bar of reamer is directly connected with boring machine, and in process, knife bar axially loaded is larger, and easily flexural deformation, causes the upper deep hole 61 of described casing part 6 and the machining accuracy of lower deep hole 62 not high.For ensureing the upper deep hole 61 of casing part 6 and the machining accuracy of lower deep hole 62, generally adopt high-accuracy machining center to process, but this kind equipment is expensive, input-output ratio is excessive, and economy is not high.
Utility model content
The technical problems to be solved in the utility model is to provide the reamer of the deep hole processing that a kind of precision is higher.
For solving the problems of the technologies described above, the utility model is taked following technical scheme;
A kind of reamer of deep hole processing, comprise handle of a knife, knife bar and blade, described knife bar comprises connecting portion: also comprise top and keeper, described handle of a knife left end is provided with pilot hole, the aperture of described pilot hole is greater than the diameter of the connecting portion of described knife bar, on described pilot hole, be provided with mounting groove near opening part, the width of described mounting groove is greater than the diameter of described keeper, the connecting portion of described knife bar is in the pilot hole of handle of a knife, described keeper is installed on the connecting portion of knife bar and is arranged in described mounting groove, the right-hand member of the connecting portion of described knife bar is provided with the connecting hole matching with top tip, the right-hand member of the described top pilot hole that is installed on handle of a knife, its tip is assemblied in the connecting hole of knife bar, the knife bar of described top and reamer is identical with the axial line of institute's deep hole processing.
Preferably, the width of the mounting groove of the pilot hole of described handle of a knife is greater than the diameter 2mm of described keeper.
Preferably, the aperture of the pilot hole of described handle of a knife is greater than the diameter 6mm of the connecting portion of described knife bar.
Preferably, described keeper is pin or double-screw bolt.
Compared with prior art, the utility model comprises following beneficial effect;
The reamer of deep hole processing of the present utility model, when work, its handle of a knife is connected with boring machine, the top knife bar that acts on of handle of a knife is realized axial feed, the top deep hole acting on power and the institute's machining box that knife bar produces acts on the power that knife bar produces and is axially reaching balance, walk coordinate by boring machine and can ensure that top center line overlaps with the center line of processed deep hole, because reamer center line overlaps with top center line, therefore can ensure that reamer is concentric with the deep hole of processing.Boring machine drives handle of a knife rotation, and handle of a knife drives knife bar rotation by the effect of mounting groove and keeper, thereby has realized swivel feeding.Overcome the stressed sagging producing at the other end in conventional knife bar one end by 2 of knife bars are stressed, ensured the depth of parallelism of institute's deep hole processing and the precision of perpendicularity.
Brief description of the drawings
Fig. 1 is the structural representation of casing part;
Fig. 2 is structural representation of the present utility model.
Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail;
Referring to Fig. 2, the reamer of deep hole processing of the present utility model, comprises handle of a knife 1, knife bar 4 and blade 5, and described knife bar 4 comprises connecting portion 40.As seen from Figure 2, the utility model also comprises top 2 and keeper 3, described handle of a knife 1 left end is provided with pilot hole 10, the aperture of described pilot hole 10 is greater than the diameter of the connecting portion 40 of described knife bar 4, on described pilot hole 10, be provided with mounting groove 11 near opening part, the width of described mounting groove 11 is greater than the diameter of described keeper 3, the connecting portion 40 of described knife bar 4 is arranged in the pilot hole 10 of handle of a knife 1, described keeper 3 is installed on the connecting portion 40 of knife bar 4 and is arranged in described mounting groove 11, the right-hand member of the connecting portion 40 of described knife bar 4 is provided with the connecting hole 41 matching with top 2 tip, described top 2 are installed on the right-hand member of the pilot hole 10 of handle of a knife 1, its tip is assemblied in the connecting hole 41 of knife bar 4, described top 2 is identical with the axial line of institute deep hole processing with the knife bar 4 of reamer.So, the reamer of deep hole processing of the present utility model, when work, its handle of a knife 1 is connected with boring machine, top 2 of handle of a knife 1 acts on knife bar 4 and realizes axial feed, top 2 act on deep hole on power and the institute's machining box that knife bar 4 produces acts on the power that knife bar 4 produces and is axially reaching balance, walk coordinate by boring machine and can ensure that top 2 center lines overlap with the center line of processed deep hole, because reamer center line overlaps with top 2 center lines, therefore can ensure that reamer is identical with the axial line of institute deep hole processing.Boring machine drives handle of a knife 1 to rotate, and handle of a knife 1 drives knife bar 4 to rotate by mounting groove 11 and the effect of keeper 3, thereby has realized swivel feeding.Overcome the stressed sagging producing at the other end in conventional knife bar one end by 4 two of knife bars are stressed, ensured the depth of parallelism of deep hole processing and the precision of perpendicularity.
The width of the mounting groove 11 of the pilot hole 10 of described handle of a knife 1 is greater than the diameter 2mm of described keeper 3, to put into smoothly groove 11 with keeper 3.
The aperture of the pilot hole 10 of described handle of a knife 1 is greater than the diameter 6mm of the connecting portion 40 of described knife bar 4, so that knife bar 4 packs pilot hole 10 smoothly into.
Referring to Fig. 2, described keeper 3 is pin, can be also double-screw bolt.This make keeper 3 simple in structure, manufacture and install than being easier to.
