Abstract
The invention relates to a bed for a machine tool, in particular to a flat bed with two triangular guide rails. The flat bed comprises a bed body and a main triangular guide rail arranged on one side of the top of the bed body, wherein an auxiliary triangular guide rail which is the same as the main triangular guide rail is arranged on the other side of the top of the bed body symmetrically. Due to the structure, the flat bed has the advantages of improving the non-cylindricity and roughness of machined parts and reducing using cost.
Description
Technical field
The present invention relates to lathe lathe bed in the mechanical production devices, especially a kind of processing parts not post degree and roughness and two triangle guide rail level bed bodies of reducing use cost of improving.
Background technology
In recent years, lathe is constantly development in mechanical processing industry, for guaranteeing the precision of machine tooling machine components, people update this body structure of lathe and the modular construction on it, improve machining accuracy, generally improve around other parts such as processing work or cutter walking track and anchor clamps, wherein particularly outstanding to improve anchor clamps.Yet some small batch part processing such as, machining slender shaft, as the need special fixture, just make use cost increase, and uncertainly can guarantee required linearity or other required precision.
As everyone knows, the machine tooling part precision mainly is to lean on the stability of track to decide, and track is arranged on the lathe bed.Referring to accompanying drawing 1, the lathe of prior art comprises lathe bed body 1, is separately positioned on a main triangle guide rail 2 and a level gauge 3 on both sides, lathe bed body 1 top with the level bed body.Saddle is installed above the lathe bed, upper slide rest and knife rest are installed on the saddle, saddle is vertical move left and right on lathe bed, moves and finishes on its main triangle guide rail 2 and level gauge 3.Yet the linearity precision of machined into part axial is decided by main triangle guide rail 2 and the level gauge 3 that is oppositely arranged with it, because the lathe bed manufacturability of this structure is simple, makes easily, and its guidance quality is poor, and the processing work lines is fuzzy; Because in use, saddle and lathe bed contact-making surface are leading rail level 201, main triangle guideway guide pass 202 and level gauge guide pass 301 of main triangle guide rail, in case main triangle guide rail is dominated arbitrary surface wear in rail level 201, main triangle guideway guide pass 202 and the level gauge guide pass 301, its original lathe guiding accuracy that dispatches from the factory will change, and the lathe after the guiding accuracy that dispatches from the factory changes just can't guarantee the linearity and the roughness of institute's processing parts.That is to say, adopt the lathe of prior art level bed body structure, when processing parts, its linearity low precision, lines is fuzzy, and roughness is poor, and in the working shaft-like part, it is particularly outstanding that this low precision shows; Must often debug lathe, increase use cost.
Even the level bed body of said structure is used for Digit Control Machine Tool, its precision also can't bigger improve, through experiment, uses the Digit Control Machine Tool of this level bed body structure, and post degree and roughness are not respectively 0.02/300 and Ra≤1.6 for they.For guaranteeing requirement on machining accuracy, part must be carried out secondary even repeatedly processing, increased use cost.
In sum, use the lathe of prior art level bed body, can't guarantee processing parts linearity, roughness requirement, the use cost height.
Summary of the invention
The objective of the invention is in order to overcome the prior art above shortcomings, a kind of processing parts not post degree and roughness and two triangle guide rail lathe beds of reducing use cost of improving are provided.
The present invention is achieved by the following technical solutions, a kind of pair of triangle guide rail level bed body, comprise the lathe bed body, be arranged on lathe bed body top main triangle guide rail on one side, wherein: Yi Bian described lathe bed body top is symmetrically arranged with the secondary triangle guide rail identical with main triangle guide rail in addition.
The bottom of the described lathe bed body of present embodiment is provided with mounting base.
The mounting base of this structure is provided with installing hole.
The present invention is owing to the advantage that has adopted said structure to have is: improved the not post degree and the roughness of institute's processing parts, also reduced use cost.
Description of drawings
The present invention can further specify by the non-limiting embodiment that accompanying drawing provides.
Fig. 1 is the structural representation of prior art level bed body.
Fig. 2 is a structural representation of the present invention.
Among the figure: 1, lathe bed body; 2, main triangle guide rail; 201, the leading rail level of main triangle guide rail; 202, main triangle guideway guide pass; 3, level gauge; 301, level gauge guide pass; 4, secondary triangle guide rail; 401, the leading rail level of secondary triangle guide rail; 402, secondary triangle guideway guide pass; 5, mounting base.
The specific embodiment
The invention will be further described below in conjunction with drawings and Examples:
Referring to accompanying drawing 2, the two triangle guide rail level bed bodies among the figure comprise lathe bed body 1, are arranged on lathe bed body 1 top main triangle guide rail 2 on one side, wherein: Yi Bian described lathe bed body 1 top is symmetrically arranged with the secondary triangle guide rail 4 identical with main triangle guide rail 1 in addition.
The bottom of the described lathe bed body 1 of present embodiment is provided with mounting base 5.Be convenient to install with the lathe working reference plane.
The mounting base 5 of this structure is provided with installing hole.Be convenient to be fixed in efficiently the lathe working reference plane.
This structure is used for lathe or Digit Control Machine Tool is that the saddle that upper slide rest and knife rest work-will be installed like this is installed in lathe bed, make saddle vertical move left and right on lathe bed, simultaneously saddle is led by main triangle guide rail 2 and secondary triangle guide rail 4, particularly, the leading rail level 201 of the main triangle guide rail of lathe bed upper rail, main triangle guideway guide pass 202, the leading rail level 401 of secondary triangle guide rail contact with saddle simultaneously with secondary triangle guideway guide pass 402 and lead.This has just strengthened the stability that saddle moves on lathe bed, the contact rigidity strengthens, absorbing enhancing, the service life of prolongation guide rail; Thereby the precision of using this structure lathe, particularly surface roughness and post degree have not been improved.This structure is used for Digit Control Machine Tool, through experiment, its not post degree and roughness be respectively 0.008/300 and Ra≤0.8, the part lines that processes is clear.
Said structure is not limited to and is used for lathe or Digit Control Machine Tool, also is not limited to the level bed body, also can be used for other lathe bed or mechanical production devices.
In sum, the present invention was because described structure was the location, and not post degree and roughness that it has improved institute's processing parts have also reduced use cost.
