Specific embodiment
The invention will be further described with reference to the accompanying drawings and examples:
Embodiment 1
It will be seen from figure 1 that a kind of double parallel concrete core sample cutter device of the present embodiment, including workbench 1, work
The upper table surface of platform 1 offers slideway 11, and the inside of slideway 11 is equipped with cutting tool 2, figure it is seen that cutting tool 2 by
Driving motor 21, main shaft 22, first bearing 23, second bearing 24, block form blade 25, connecting rod 26, crossbeam 27 and 28 groups of idler wheel
At the output end of driving motor 21 is set with main shaft 22, and the outer ring fixing sleeve of main shaft 22 is equipped with block form blade 25, block form knife
The disk-type blades that piece 25 is parallel to each other by two groups form, and the lower end of blade extends to the inside of double-pole slot 311, the bottom of blade
With the inside groove face interval 8mm-12mm of double-pole slot 311, blade caused by avoiding feed process excessive damages phenomenon, to coagulation
Core sample and block form blade 25 generate protection effect simultaneously, and after concrete core sample cutting, two cut surface is parallel, with after an action of the bowels
Continuous processing, the two sides of main shaft 22 are separately installed with first bearing 23 and second bearing 24, and the output end of driving motor 21 runs through the
One bearing 23 and with 22 fixing assembling of main shaft, driving motor 21 drives 22 fixed-axis rotation of main shaft, thus the high speed of block form blade 25
Rotation drives driving motor 21 to be fixedly mounted on the side of first bearing 23, first bearing 23, second bearing to be cut
24 assemble with the activity of main shaft 22 respectively, and first bearing 23 carries driving motor 21, and with supports main shaft 22 together of second bearing 24
It is rotated, the outer ring of first bearing 23 and second bearing 24 is fixedly connected to connecting rod 26, installs between adjacent connecting rod 26
There is a crossbeam 27, the both ends of crossbeam 27 and 26 fixing assembling of connecting rod, crossbeam 27 are separately connected first bearing 23 and the by connecting rod 26
Two bearings 24, when crossbeam 27 is displaced, cutting tool 2 is whole to be translated, thus change the distance between core sample to be cut, it is horizontal
The outer ring of beam 27 is set with idler wheel 28, and crossbeam 27 is cooperated by 11 activity of slideway of idler wheel 28 and 1 upper table surface of workbench, idler wheel 28
Inner ring and crossbeam 27 it is relatively fixed, the outer ring of idler wheel 28 is slided the inside of slideway 11 is opposite, and idler wheel 28 can be self-locking.
From figure 3, it can be seen that the following table of workbench 1 is equipped with limiting device 3, from Fig. 4-5 as can be seen that limiting device
It 3 by bottom plate 31, fixing bolt 32, adjusts bolt 33, limit plate 34 and binds bolt 35 and form, offered in the plate face of bottom plate 31
Double-pole slot 311, the upper surface equidistant interval of bottom plate 31 are equipped with fixing bolt 32, and the upper surface of bottom plate 31 is also spaced and is fitted with tune
Bolt 33 is saved, limit plate 34 is installed between adjacent adjusting bolt 33, bolt 35 is bound in the plate face of limit plate 34,
Limit plate 34 is by binding bolt 35 and adjusting 33 fixing assembling of bolt.
Bottom plate 31 is detachably assembled by fixing bolt 32 and workbench 1, and after the completion of cutting, removable lower table 1 is carried out
Individually cleaning, so that cleaning, attended operation adjust bolt 33 and 31 activity of bottom plate assembled, adjust bolt 33 more for safety
It is vertically arranged in the plate face of bottom plate 31, limit plate 34 is horizontally disposed in the upper end for adjusting bolt 33, and limit plate 34 compresses coagulation
Core sample is to achieve the effect that limit, at the same time, by tightening or adjusting pine to adjust bolt 33, can also adjust limit plate 34
With the spacing between bottom plate 31, so as to match various sizes of concrete core sample.
A kind of cutting method of double parallel concrete core sample cutter device, the steps include:
Step 1: polishing sampling takes concrete core sample that its surface is tentatively polished, and laid flat to the upper table of bottom plate 31
Face, when laying flat, concrete core sample bottom surface and the upper surface of bottom plate 31 are bonded to each other, and irregular shape also can be selected in concrete core sample
Shape, when selecting irregular shape, it is only necessary to its bottom surface of polishing enables its bottom surface to lie in the upper surface of bottom plate 31, do not generate compared with
Wide arc gap；
Adjusting bolt 33: being spaced the upper surface for being inserted into bottom plate 31 by step 2, and concrete core sample is placed in adjacent adjusting
Between bolt 33, limit plate 34 is fitted in the upper surface of concrete core sample, by binding bolt 35 for limit plate 34 and adjusting spiral shell
33 fixing assembling of bolt, and tighten and adjust bolt 33, the fixation to concrete core sample is completed, by tightening or adjusting pine to adjust bolt
33, i.e., the spacing between adjustable limit plate 34 and bottom plate 31 improves whole dress to match various sizes of concrete core sample
The practicability and applicability set；
Step 3: bottom plate 31 is mounted on to the surface of workbench 1 by fixing bolt 32, tightening fixing bolt 32 can be real
Existing bottom plate 31 is completely fixed, conversely, bottom plate 31 can be removed by unclamping fixing bolt 32；
Step 4: starting driving motor 21,25 fixed-axis rotation of block form blade, crossbeam 27 is by idler wheel 28 in slideway 11
Inside is opposite to be slided, and crossbeam 27 drives 25 horizontal displacement of block form blade and generates to concrete core sample and cuts, in cutting process
Spray cooling is carried out to the surface of block form blade 25, concrete core sample, block form blade 25 is avoided to overheat and damage；
Step 5: after the completion of cutting, crossbeam 27 resets, and driving motor 21 is closed, so that block form blade 25 is far from coagulation
Core sample provides certain safe distance；
Step 6: successively removing and bind bolt 35 and limit plate 34, takes out concrete core sample, removes bottom plate 31, Ji Keqing
Manage the table top of bottom plate 31 and workbench 1.
When batch machining produces, step 1-6 is repeated.
It is cut when device is cut using double-pole hand in hand, while two working faces of concrete core sample is cut, cut
After cutting, two machined surface is substantially parallel, and has abandoned conventional cutting method, cutting cycle is shortened half, effectively accelerates life
Efficiency is produced, while mechanical energy depletion is few, cutting cost reduces, and in cutting process, operator can pass through hand steered crossbeam 27 or company
Bar 26 translates cutting tool 2, and without artificial portable cutting tool 2, working strength is significantly reduced, security performance significant increase.
The present invention drives 2 integral translation of cutting tool by crossbeam 27, thus change the distance between core sample to be cut,
The disk-type blades that block form blade 25 is parallel to each other by two groups form, and after concrete core sample cutting, two cut surface is parallel,
So as to following process, be not necessarily to secondary polishing, bottom plate 31 can remove carry out individually cleaning, cleaning, attended operation more for safety,
Limit plate 34 compresses concrete core sample to achieve the effect that limit, by tightening or adjusting pine to adjust bolt 33, can also adjust
Spacing between limit plate 34 and bottom plate 31 so as to match various sizes of concrete core sample, and then improves single unit system
Practicability and applicability.
Schematically the present invention and embodiments thereof are described above, description is not limiting, institute in attached drawing
What is shown is also one of embodiments of the present invention, and actual structure is not limited to this.So if the common skill of this field
Art personnel are enlightened by it, without departing from the spirit of the invention, are not inventively designed and the technical solution
Similar frame mode and embodiment, are within the scope of protection of the invention.
