Abstract
The utility model discloses a high-precision heavy type machine tool foundation secondary grouting material guiding opening which belongs to the technical field of a machine tool foundation. A foundation bolt is arranged at the center of a foundation preset pit and is fixed by grouted aggregate concrete through a primary grouting material guiding opening. The upper end of the foundation bolt is provided with a foundation snap ring, an adjusting iron cushion block and a foundation positioning sleeve respectively from bottom to top. The secondary grouting material guiding opening above the foundation preset pit is composed of a semi-bucket-shaped structure and a semi-T-shaped structure. Hereon, concrete is grouted to a position which is level to the ground. The shape of the secondary grouting material guiding opening above the foundation pit is improved, and a problem of inferior secondary grouting quality caused by grouting material residue at the material guiding opening is settled. Because the foundation after secondary grouting is level to the ground and is excellently fused, high precision and good retaining property of the machine tool after mounting are ensured.
Description
Technical field
The utility model relates to a kind of high-precision heavy machine tool ground back-grouting and draws material mouthful, belongs to machine tool basic technical field.
Background technology
Current, machine industry making lathe ground process is taken seriously degree and is nowhere near, and ground matrix manufacturing is second-rate.Simultaneously go to toward ignoring foundation quality is detected at Installing machine tool, cause after Installing machine tool precision stability and precision stability poor, especially high-precision heavy machine tool is because precision own is higher, own wt is larger, therefore very strong to the sensitiveness of ground.In the time of ground matrix manufacturing, to carry out twice grouting to basis from drawing material mouth, draw material mouthful owing to sharing one, in the time being in the milk for the first time, grouting material can remain in and draw material mouthful place, the residue and the back-grouting material that while causing back-grouting, draw material mouthful place can not combine together, affect back-grouting quality, so just require us to make good ground as basis, avoid occurring that precision is unstable after Installing machine tool, the poor problem that can not normally use of causing of retentivity, avoid having caused huge economic loss to machine tool manufacturers and user.
Summary of the invention
The utility model provides a kind of high-precision heavy machine tool ground back-grouting to draw material mouthful, and object is to improve back-grouting and draws material mouth-shaped, guarantees that ground and back-grouting ground and lathe that once grouting forms become a rigid body.
The utility model solves the technical scheme that its technical problem adopts: at center, the reserved hole of lower margin, stone bolt is set, draws material mouthful concrete grouting fix by once grouting.Stone bolt upper end is respectively equipped with from the bottom to top successively lower margin snap ring, adjusts parallels and lower margin positioning sleeve.It is half bucket half T shape structure that back-grouting above the reserved hole of lower margin is drawn material mouthful, extremely concordant with ground with concrete grouting from here.
The beneficial effects of the utility model are: above lower margin hole, improved back-grouting and drawn material mouth-shaped, solved grouting material residue and stayed and draw material mouthful place and affect a problem for back-grouting quality.Due to back-grouting groundwork and ground one is flat and well merge, guarantee to install rear machine tool accuracy stable, retentivity is good.The utility model is under the jurisdiction of the great special problem 2010ZX04001-031 of national science and technology.
Brief description of the drawings
Below in conjunction with the drawings and specific embodiments, the utility model is further illustrated.
Fig. 1 is that the high-precision heavy machine tool ground of the utility model back-grouting is drawn material mouth structure schematic diagram.
Number in the figure:
1. adjust parallels 2. once grouting and draw the reserved hole of material mouthful 3. foundation pit 4. lower margins
5. stone bolt 6. back-groutings are drawn material mouthful 7. lower margin snap ring 8. lower margin positioning sleeves
9. machine anchor.
Detailed description of the invention
Shown in Figure 1, at 4 centers, the reserved hole of lower margin, stone bolt 5 is set, draw material mouthful 2 use concrete groutings by once grouting and fix.Stone bolt 5 upper ends are respectively equipped with from the bottom to top successively lower margin snap ring 7, adjust parallels 1 and lower margin positioning sleeve 8.It is half bucket half T shape structure that back-grouting above the reserved hole 4 of lower margin is drawn material mouth 6, extremely concordant with ground with concrete grouting from here.
Making in lathe ground process, make foundation pit by foundation drawing paper size.Ensure once to draw the size in material mouth 2 and the reserved hole 4 of lower margin, surface cleaning.On request stone bolt 5 is fixed on behind the reserved hole 4 of lower margin, firm from once drawing material mouthfuls 2 health of being in the milk, and detect qualified.Back-grouting above the reserved hole 4 of lower margin is drawn material mouthfuls 6 and is carried out the grouting of second coagulation soil to concordant with ground, and its surface area should be greater than the area of adjusting parallels 1, and detect qualified.Be in the milk after health firmly until stone bolt 5, on stone bolt 5, put respectively lower margin snap ring 7 and adjust parallels 1, machine anchor 9 is hung on stone bolt 5, carrying out attitude updating by adjusting parallels 1, fixing with lower margin positioning sleeve 8, the qualified rear installation lathe of inspection ground.Guarantee that ground and back-grouting ground and lathe that once grouting forms become a rigid body.
