A kind of digging tool of crushing hard rock of disk cutter is installed on the large-scale no-dig technique such as shield, TBM, push pipe and applies
The head of construction equipment, effect are cutting face rocks and peel off rock from face.It is widely used in subway
Tunnel, railway tunnel, seepage tunnel and Urban Buried Pipeline Network construction work.Installation cone roller inside main disk cutter at present
Lubricant is injected in bearing, floating seal, inner cavity.It needs to pre-tighten cutter before use, it is stringent to seal request, lubricating oil
Leakage can cause the serious consequences such as rolling blade losing efficacy.In general, the radial dimension of disk cutter is bigger, for certain positions by
The cutting apparatus of limit, current design cannot be satisfied requirement.
Utility model content
For the deficiency in above-mentioned background technology, the utility model proposes a kind of miniature disk cutter of single-blade, solve existing
There is in technology disk cutter installation need to pre-tighten, installation dimension is big, the higher problem of cost.
What the technical solution of the utility model was realized in：A kind of miniature disk cutter of single-blade, including cutter shaft and cutter hub,
Cutter hub includes integrally formed cutter ring and blade, and cutter ring is connected to one end of cutter shaft by sliding bearing, and one end of cutter ring is stretched out
Cutter shaft, cutter ring stretching cutter shaft part are internally provided with axle end baffle plate and end cap, and axle end baffle plate is fixedly connected by screw with cutter shaft,
End cap is threadedly coupled with cutter ring.
The inner wall of the cutter ring is equipped with positioning convex platform, and positioning convex platform is equipped with toroidal cavity, and sliding bearing is symmetrical arranged
It matches in the both sides of toroidal cavity and with positioning convex platform.
Gap is equipped between symmetrically arranged sliding bearing, gap is corresponding with toroidal cavity.
It is connected by flat key between the sliding bearing and cutter shaft.
One end that the cutter ring stretches out cutter shaft is equipped with internal thread, and internal thread is matched with the external screw thread on end cap；Cutter ring is stretched
Sealing ring is equipped between one end and cutter shaft of feed shaft.
The outer diameter of the axle end baffle plate is less than the internal diameter of cutter ring.
The utility model is a kind of miniature disk cutter of single-blade, and roller bearing is replaced using symmetrically arranged sliding bearing,
Compact-sized, bearing capacity is strong, not tight to seal request, need not pre-tighten, and use cost is cheap, is limited suitable for position hard
Rock cutter device.
Description of the drawings
It, below will be to attached drawing needed in embodiment description in order to illustrate more clearly of the utility model embodiment
It is briefly described, it should be apparent that, the accompanying drawings in the following description is only some embodiments of the utility model, for ability
For the those of ordinary skill of domain, without creative efforts, it can also be obtained according to these attached drawings other attached
Figure.
Fig. 1 is the utility model whole interior structural schematic diagram.
Fig. 2 is the utility model structure of the cutter body schematic diagram.
Specific implementation mode
The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model
Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole
Embodiment.Based on the embodiments of the present invention, those of ordinary skill in the art are not under the premise of making the creative labor
The every other embodiment obtained, shall fall within the protection scope of the present invention.
As shown in Figs. 1-2, the miniature disk cutter of a kind of single-blade, including cutter shaft 1 and cutter hub 2, cutter hub 2 include integrally formed
Cutter ring 21 and blade 22, cutter ring 21 are connected to one end of cutter shaft 1 by sliding bearing 3, and sliding bearing 3 uses the sliding with crimping
Bearing is connected by flat key 7 between sliding bearing 3 and cutter shaft 1, is steadily connect with cutter ring convenient for sliding bearing, is used to support
Cutter shaft 1 is stretched out in one end of cutter ring, cutter ring 21, and 1 part of the stretching cutter shaft of cutter ring 21 is internally provided with axle end baffle plate 4 and end cap 6, shaft end
The outer diameter of baffle 4 is less than the internal diameter of cutter ring 21, is convenient for the installation of axle end baffle plate.Axle end baffle plate 4 is fixed by screw 5 and cutter shaft 1
Connection, plays the role of axial restraint bearing, end cap 6 is threadedly coupled with cutter ring 21.The inner wall of the cutter ring 21 is equipped with positioning
Boss 23, positioning convex platform 23 be equipped with toroidal cavity 24, sliding bearing 3 be symmetricly set on the both sides of toroidal cavity 24 and with positioning
Boss 23 matches.Between symmetrically arranged sliding bearing 3 be equipped with gap 9, gap 9 is corresponding with toroidal cavity 24, gap 9 and
Toroidal cavity 24 plays lubricating action for storing extreme pressure grease to cutter shaft and sliding bearing.
One end that the cutter ring 21 goes out cutter shaft 1 is equipped with internal thread, and internal thread is matched with the external screw thread on end cap 6, dismounts
It is convenient, convenient for checking cutter ring inner workings；Cutter ring 21 puts in and is equipped with sealing ring 8 between one end of cutter shaft 1 and cutter shaft 1, close
Seal 8 uses Glais ring, the lubricant for being stored in sealed knife circle toroidal cavity.
Since the cutter ring size is smaller, stress is also relatively small when cutting, so the utility model and cutter shaft cantilever support
Mode, rear end fixed with nut, forms single-blade hob, improves stock-removing efficiency.
