Abstract
The utility model relates to a machine tool body belonging to the field of machine tools. The machine tool body is an integral cast part and comprises a tool body, a main shaft guide rail, an auxiliary shaft guide rail and a cutter platform, wherein the cutter platform is provided with a front-row cutter rest, a rear-row cutter rest and a third cutter rest; the front-row cutter rest is parallel to the rear-row cutter rest; a cutter of the front-row cutter rest is vertical to a cutter of the rear-row cutter rest in different planes; the third cutter rest is arranged on one side of the rear-row cutter rest; a cutter of the third cutter rest is vertical to the cutter of the front-row cutter rest in different planes; and the cutter of the third cutter rest is parallel to the cutter of the rear-row cutter rest in different planes. The tool body, the main shaft guide rail, the auxiliary shaft guide rail and the cutter platform are integrally cast, the whole machine tool is ensured to have the same strength and rigidity, and the whole machine tool is also ensured to have the same protruding value. Therefore, by using the machine tool body with the structure to machine workpieces, the accuracy can be better maintained, and the service life of the machine tool can be prolonged.
Description
Technical field
The utility model relates to a kind of lathe, especially relates to a kind of lathe bed body.
Background technology
Lathe bed body is one of critical piece of lathe, and the performance of lathe bed body itself directly affects the service life of lathe, and is also most important for the precision that keeps process component simultaneously.Present lathe bed body mostly is the foundry goods assembly, but, because the hardness of foundry goods is different with rigidity, the projection value alters a great deal, even same bed body, with same pressure, the numerical value maximum difference of projection can reach more than the 0.6mm, and the value of each section projection presents nonlinear state and scrambling in the longitudinal direction, therefore, has the uniformity of 20% bed body hardness not meet national standard.Need interim processing to use, must be through grinding and secondary quenching.In secondary quenching, occur the guide rail surface scaling loss easily or crackle is scrapped, so not only increased cost, and the quality of lathe bed body is not high yet.
Summary of the invention
The purpose of this utility model is to provide a kind of technical scheme, and the technical program can solve the prior art problem and shortage.Lathe bed body of the present utility model adopts monoblock cast to form, thereby has solved problem such as different with rigidity and the protruding value variation of hardness.
The technical solution of the utility model is achieved by following technical measures.Lathe bed body of the present utility model comprises a body body, guide rail and tool table, and described guide rail and described tool table are positioned on the described bed body body, and its special feature is: described bed body body, described guide rail and described tool table are the monoblock cast part.
In order to improve the beneficial effect of technical solutions of the utility model, the special feature of the utility model lathe bed body also is: gang feed tool rack and back gang feed tool rack before described tool table is provided with, described preceding gang feed tool rack and described back gang feed tool rack are parallel to each other.
In order to improve the beneficial effect of technical solutions of the utility model, the special feature of the utility model lathe bed body also is: the cutter of gang feed tool rack is vertical with the cutter antarafacial of described back gang feed tool rack before described.
In order to improve the beneficial effect of technical solutions of the utility model, the special feature of the utility model lathe bed body also is: a side of described back gang feed tool rack is provided with three-tool post.
In order to improve the beneficial effect of technical solutions of the utility model, the special feature of the utility model lathe bed body also is: the cutter of described three-tool post is vertical with the cutter antarafacial of described preceding gang feed tool rack; The cutter of described three-tool post is parallel with the cutter antarafacial of described back gang feed tool rack.
In order to improve the beneficial effect of technical solutions of the utility model, the special feature of the utility model lathe bed body also is: described guide rail comprises main shaft guide rail and countershaft guide rail, and described main shaft guide rail is vertical mutually with described countershaft guide rail.
The beneficial effect of technical solutions of the utility model can be known by the statement of abovementioned technology.Lathe bed body of the present utility model adopts monoblock cast to form, this cast-in-block lathe bed body has guaranteed that at first bed body body, main shaft guide rail, the countershaft guide rail of lathe have identical hardness and rigidity with tool table, and guarantee that also lathe bed body body, main shaft guide rail, countershaft guide rail and tool table have identical projection value.Therefore, use the lathe bed body processing of this structure can keep workpiece to have higher precision, can prolong the service life of lathe simultaneously.This shows that compared with prior art, the utlity model has substantive distinguishing features and technological progress, the beneficial effect of its enforcement also is conspicuous.
Description of drawings
Fig. 1 is the structural representation of the utility model specific embodiment.
Among the figure, 1 is bed body body, and 2 is the main shaft guide rail, and 3 is the countershaft guide rail, and 4 is three-tool post, and 5 is the back gang feed tool rack, and 6 is preceding gang feed tool rack.
The specific embodiment
For clearly demonstrating the technical characterstic of this programme,, and, this programme is set forth in conjunction with its accompanying drawing below by a specific embodiment.
By accompanying drawing 1 as can be seen, lathe bed body of the present utility model, comprise a body body 1, main shaft guide rail 2, countershaft guide rail 3 and tool table 7, main shaft guide rail 2, countershaft guide rail 3 and tool table 7 are positioned on the body body 1, and bed body body 1, main shaft guide rail 2, countershaft guide rail 3 and tool table 7 are the monoblock cast part.Tool table 7 is provided with preceding gang feed tool rack 6, back gang feed tool rack 5 and three-tool post 4, and preceding gang feed tool rack 6 is parallel to each other with back gang feed tool rack 5, and the cutter of preceding gang feed tool rack 6 is vertical with the cutter antarafacial of back gang feed tool rack 5; Three-tool post 4 is positioned at a side of back gang feed tool rack 5, and the cutter of three-tool post 4 is vertical with the cutter antarafacial of preceding gang feed tool rack 6, and the cutter of three-tool post 4 is parallel with the cutter antarafacial of back gang feed tool rack 5.
Bed body body 1, main shaft guide rail 2, countershaft guide rail 3 and the tool table 7 of lathe bed body of the present utility model adopt monoblock cast to form, this cast-in-block lathe bed body has guaranteed that at first bed body body 1, main shaft guide rail 2, the countershaft guide rail 3 of lathe have identical hardness and rigidity with tool table 7, and guarantees that also bed body body 1, main shaft guide rail 2, countershaft guide rail 3 have identical projection value with tool table 7.Therefore, use the lathe bed body processing work of this structure can keep precision preferably, can prolong the service life of lathe simultaneously.
