Abstract
It the utility model is related to a kind of cutter being used for reaming in natural rock drilling progress, including drilling rod, low bottom-disc, top bottom-disc, shell, blade shaft and blade, low bottom-disc and top bottom-disc are fixed on drilling rod, card of the casing in top bottom-disc and low bottom-disc, two blade shafts are installed, blade shaft is used to fix blade in the card of low bottom-disc.Cutter provided by the utility model only relies on the relative motion of low bottom-disc and shell to control the stretching of blade and retraction, therefore whole fluting or reaming procedure can control only by the direction and rotating speed of control drilling rod.The structure of whole cutter is simple, easy to use.
Description
Technical field
The utility model belongs to broaching equipment, more particularly to a kind of knife being used for reaming in natural rock drilling progress
Tool.
Background technology
Counterboring apparatus of the prior art can only expand original drilling of rock, it is impossible to keep the straight of original drilling
Bore inner is enlarged under footpath.
The content of the invention
The utility model provides a kind of cutter being used for reaming in natural rock drilling progress, is not expanding upper bore
In the case of to natural rock bore inner carry out reaming.
Therefore, the technical solution adopted in the utility model is：
A kind of cutter being used for reaming in natural rock drilling progress, including drilling rod, low bottom-disc, top bottom-disc, shell, knife
Piece rotating shaft and blade, low bottom-disc and top bottom-disc are fixed on drilling rod by fixing bolt and fixing nut, and casing is in top bottom-disc
With the card of low bottom-disc, two blade shafts are installed in the card of low bottom-disc, blade shaft is used to fix blade.
A kind of cutter being used for reaming in natural rock drilling progress as described above, wherein, it is provided with the shell
The hole matched with blade sizes, blade can be stretched out by the hole from shell；And the face of cylinder is processed into the side in hole.
A kind of cutter being used for reaming in natural rock drilling progress as described above, wherein, it is provided with the shell
Mudhole, caused landwaste in reaming procedure can be allowed to be flowed out from cutter interior.
A kind of cutter being used for reaming in natural rock drilling progress as described above, wherein, the drilling rod is provided with phase
Logical water filling port and discharge outlet, caused plaster in reaming procedure can be rushed in process with given pace sustained water injection
Go out.
A kind of cutter being used for reaming in natural rock drilling progress as described above, wherein, the low bottom-disc processing
Limited location block, can limiting blade, opposing blades rotating shaft institute gyration will not be excessive in reaming procedure.
Compared with prior art, effectively result of the present utility model is：
Because the cutter relies on the relative motion of upper low bottom-disc and shell to control the stretching of blade and retraction, therefore entirely
Fluting or reaming procedure can control only by the direction and rotating speed of control drilling rod.The structure of whole cutter is simple, uses
It is convenient.
Brief description of the drawings
The following drawings is only intended to, in doing the utility model schematic illustration and explanation, not limit model of the present utility model
Enclose.Wherein,
Fig. 1 is a kind of assembling schematic diagram being used for the cutter of reaming in natural rock drilling progress of the utility model；
Fig. 2 is the schematic cross-section when stretching of the utility model blade reaches maximum reaming radius；
Fig. 3 is schematic cross-section when the utility model blade is retracted.
Explanation is marked in figure：1st, fixing nut；2nd, top bottom-disc；3rd, shell；4th, blade；5th, low bottom-disc；6th, blade shaft；7、
Drilling rod；8th, fixing bolt；I, water filling port；II, mudhole；III, limited block；IV, discharge outlet.
Embodiment
In order to which the technical characteristics of the utility model, purpose and effect are more clearly understood, below by specific
Examples of implementation are simultaneously described in further detail with reference to accompanying drawing to the utility model.
As shown in figure 1, the utility model Cutting tool installation manner view, a kind of knife being used for reaming in natural rock drilling progress
Tool, is made up of top bottom-disc 2, blade 4, shell 3, low bottom-disc 5, drilling rod 7.Wherein, drilling rod is provided with the water filling port I communicated and draining
Mouth IV；Mudhole II is provided with shell 3；Limited block III and blade shaft 6 are machined with the card of low bottom-disc 5；Top bottom-disc 2 is with
Chassis 5 is fixed on drilling rod 7 by fixing bolt 8 and fixing nut 1.
As shown in Fig. 2 during work, cutter is inserted in the drilling of natural rock, start to note with appropriate speed to water filling port I
Water, keep discharge outlet IV to continue water outlet and constantly go out caused landwaste in whole work process；Then driven with motor
The rotate counterclockwise of drilling rod 7, top bottom-disc 2, low bottom-disc 5 is driven to rotate.Due to inertia, the meeting of low bottom-disc 5 opposite shell 3 occurs counterclockwise
Corner, the opposing blades rotating shaft 6 of blade 4 is turned clockwise, so as to be stretched out by shell 3, constantly cut under the drive of drilling rod 7
Inside hole wall.Centrifugal force when blade 4 is cut when suffered resistance and rotation can further increase the opposing blades rotating shaft 6 of blade 4
The angle to turn clockwise, the length that blade 4 stretches out is continuously increased, is finally reached maximum radius of clean-up, realized in hole and expand
Hole.Limited block III ensure that blade 4 after maximum reaming radius is reached, will not rotate polygonal during rock cutting
Spend and retracted from opposite side.
As shown in figure 3, after the completion of work, stop water filling, then stop the rotation, due to inertia, shell 3 can relative bottom
Corner counterclockwise occurs for disk 5, blade 4 is made rotate counterclockwise around blade shaft 6, is finally retracted in shell 3 and is returned to initially
State, it can now extract cutter out.Limited block III ensure that blade 4 will not rotate multi-angle during blade is withdrawn,
It is entirely retracted to depart from the constraint of shell 3 inside device.
Described above is the schematical embodiment of the utility model, is not limited to model of the present utility model
Enclose.Any those skilled in the art, the equal change made on the premise of design of the present utility model and principle is not departed from
With modification, the scope of protection of the utility model all should be belonged to.
