Description
Technical field
The utility model relates to a kind of drilling equipment, relates in particular to a kind of hobboing cutter that is provided with plug pin hole.
Background technology
At present, for mine mining field, usually need to use the auxiliary exploitation of hobboing cutter, existing mining comprises hobboing cutter body and cutter shaft substantially with hobboing cutter.When mining, hobboing cutter need be drilled rock stratum, and during probing, hobboing cutter High Rotation Speed, can produce friction between hobboing cutter body and cutter shaft.Thereby in order to reduce friction, be conducive to the rotation of hobboing cutter, between above-mentioned hobboing cutter body and cutter shaft, usually inject lubrication oil.Existing hobboing cutter is realized the injection of lubrication oil by offer oil filler point on hobboing cutter body, but this mode difficulty of processing is larger, inconvenience is installed, and sealing is poor.
Utility model content
The purpose of this utility model is to provide a kind of hobboing cutter.
For realizing above-mentioned utility model object, a kind of hobboing cutter of the present utility model, it comprises: blade, on described blade, offer plug pin hole, the central axis in described plug pin hole and the central axis of described hobboing cutter are an angle, and described plug pin hole connects described blade setting, the inside wall in described plug pin hole has a stage portion.
As further improvement of the utility model, described blade is tapered, described taper blade comprises side and the bottom surface of circular arc, and described plug pin hole one end opening is positioned on the circular arc side of described taper blade, and other end opening is positioned on the bottom surface of described taper blade.
As further improvement of the utility model, aperture corresponding to opening that is positioned at described bottom surface is greater than aperture corresponding to opening that is positioned at described arcuate flanks.
As further improvement of the utility model, the angular range of the angle between central axis and the central axis of described hobboing cutter in described plug pin hole is: 45 ~ 55 °.
As further improvement of the utility model, the angle of described angle is 50 °.
Compared with prior art, the beneficial effects of the utility model are: hob-cutter structure of the present utility model is simple, process simple and easyly, and its sealing is good, and abrasion resistance is strong, easy for installation, and highly versatile.
Accompanying drawing explanation
In order to be illustrated more clearly in the utility model embodiment or technical scheme of the prior art, to the accompanying drawing of required use in embodiment or description of the Prior Art be briefly described below, apparently, the accompanying drawing the following describes is only some embodiment that record in the utility model, for those of ordinary skills, do not paying under the prerequisite of creative work, can also obtain according to these accompanying drawings other accompanying drawing.
Fig. 1 is the plan cross-section schematic diagram of a specific embodiment of hobboing cutter of the present utility model.
The specific embodiment
Below in conjunction with each embodiment shown in the drawings, the utility model is elaborated; but should be noted that; these embodiments are not limitation of the utility model; those of ordinary skills are according to these embodiment institute work energy, method or structural equivalent transformation or alternative, within all belonging to protection domain of the present utility model.
As shown in Figure 1, the utility model hobboing cutter 100 comprises: blade 10, on above-mentioned blade 10, offer plug pin hole 101, and the central axis in above-mentioned plug pin hole 101 and the central axis of above-mentioned hobboing cutter 100 are an angle theta.This angle is an acute angle, and its angular range is: 45 ~ 55 °, preferably, this angle is 50 °.
Further, above-mentioned blade 101 is tapered, and the blade 101 of this taper has side and the bottom surface of circular arc.Above-mentioned plug pin hole 101 connects above-mentioned blade 10 and arranges, thereby the opening of 101 one end, plug pin hole is positioned on the circular arc side of above-mentioned taper blade, and other end opening is positioned on the bottom surface of described taper blade.In addition, above-mentioned plug pin hole 101 comprises the first duct 1011 and the second duct 1012, stage portion 102 on the inside wall in the formation plug pin hole 101, junction in above-mentioned the first duct 1011 and the second duct 1012, this stage portion 102 is for matching with corresponding plug pin (not shown).Thereby the aperture that is positioned at corresponding first duct 1011 of opening of above-mentioned bottom surface is greater than the aperture that is positioned at the second duct 1012 that the opening of arcuate flanks is corresponding.
In sum, hob-cutter structure of the present utility model is simple, processes simple and easyly, and its sealing is good, and abrasion resistance is strong, easy for installation, and highly versatile.
To those skilled in the art, obviously the utility model is not limited to the details of above-mentioned example embodiment, and in the situation that not deviating from spirit of the present utility model or essential characteristic, can realize the utility model with other concrete form.Therefore, no matter from which point, all should regard embodiment as exemplary, and be nonrestrictive, scope of the present utility model is limited by claims rather than above-mentioned explanation, is therefore intended to all changes that drop in the implication and the scope that are equal to important document of claim to include in the utility model.Any Reference numeral in claim should be considered as limiting related claim.
In addition, be to be understood that, although this manual is described according to embodiment, but be not that each embodiment only comprises an independently technical scheme, this narrating mode of manual is only for clarity sake, those skilled in the art should make manual as a whole, and the technical scheme in each embodiment also can, through appropriately combined, form other embodiments that it will be appreciated by those skilled in the art that.
