Abstract
The utility model discloses a workbench structure of a large high-precision vertical lathe. The workbench structure comprises a workbench main body, wherein the workbench main body comprises an outer workbench and an inner workbench detachably arranged on the outer workbench; and a bearing is arranged on the inner workbench. The workbench main body is separated into the outer workbench and the inner workbench, and the diameter of the inner workbench is reduced, so that a spindle hole can be machined on high-precision equipment (such as a vertical lathe), and the roundness accuracy of the spindle hole is 0.002-0.003.
Description
Technical field
The utility model relates to the vertical lathe workbench, relates in particular to a kind of large-scale high-precision vertical lathe Working table structure.
Background technology
Large-scale high-precision vertical lathe Working table structure existing structure is that workbench adds the taper sleeve type structure, and is as shown in Figure 1, and wherein 1 is workbench; 2 is tapered sleeve; 3 is bearing, and wherein tapered sleeve 2 is a thin-walled parts, and more than the workbench diameter 3000mm, size is bigger, and domestic equipment that can not this size of grinding can only be processed on vertical lathe, and therefore spindle hole (taper hole) circularity can't guarantee its precision between 0.01-0.02.The workbench circular runout is between 0.02mm-0.05mm, because the tapered sleeve relative thickness is thinner, the deviation from circular from of workbench taper hole echos on the tapered sleeve, finally influences the precision and the life-span of bearing.
The utility model content
The purpose of the utility model is to provide a kind of large-scale high-precision vertical lathe Working table structure, to solve in the prior art the inconvenient problem of the processing of the spindle hole on the workbench.
To achieve these goals, the technical scheme of the utility model is following:
Large-scale high-precision vertical lathe Working table structure comprises the workbench main body, it is characterized in that, said workbench main body comprises outer workbench and detachably be arranged on the interior workbench on the outer workbench that said interior workbench is provided with bearing.
In a preferred embodiment of the utility model, said interior workbench is connected with outer stationary table through bolt.
The utility model is through being split as the workbench main body outer workbench and interior workbench; Wherein the diameter dimension of interior workbench dwindles; Process to guarantee that its spindle hole can be gone up at high precision apparatus (like vertical grinder), make its precision can reach circularity between 0.002-0.003.
The characteristics of the utility model can consult this case graphic and below better embodiment detailed description and obtain to be well understood to.
Description of drawings
Fig. 1 is the prior art constructions sketch map.
Fig. 2 is the structural representation of the utility model.
The specific embodiment
For technological means, creation characteristic that the utility model is realized, reach purpose and be easy to understand understanding with effect, further set forth the utility model below in conjunction with specific embodiment.
As shown in Figure 2, large-scale high-precision vertical lathe Working table structure comprises the workbench main body; The workbench main body comprises outer workbench 100 and interior workbench 200; Interior workbench 200 detachably is arranged on the outer workbench 100, and in the present embodiment, interior workbench is connected with outer stationary table through bolt 400.
Wherein, interior workbench diameter 2500mm with through grinding, guarantees the spindle hole precision, makes the spindle hole accuracy class reach the grade identical with precision bearing, through assembled orientation, can realize the high rotating accuracy below the workbench 0.005mm.
Interior workbench middle part is thinned; Less in axial rigidity; Reduced since the power of tumbling of workbench thrust bearing guide pass and the generation of dead eye center line out of plumb to the influence of bearing; While has reduced the influence of workbench main shaft hole circle degree error to dead eye owing to rigidity on the interior workbench diameter is less, reaches the purpose of the high rotating accuracy below the workbench 0.005mm.
More than show and described the advantage of basic principle, principal character and the utility model of the utility model.The technical staff of the industry should understand; The utility model is not restricted to the described embodiments; The just principle of describing in the foregoing description and the specification of the utility model; The utility model also has various changes and modifications under the prerequisite that does not break away from the utility model spirit and scope, and these variations and improvement all fall in the scope of the utility model that requires protection.The protection domain that the utility model requires is defined by appending claims and equivalent thereof.
