Abstract
The invention discloses a method for installing a machine tool guideway, comprising the following steps: (1) the machine tool body is scraped to fabricate an installation surface matching the bottom surface of the guideway; the installation surface is close to one side of the reference surface of the machine tool and is 3-5mm away from the reference surface; the planeness of the installation surface is less than 0.004mm/500mm and the guideway is pressed on the installation surface and is fixedly connected with the machine tool body; (2) a second parallel guideway is fixed by the method in the step (1) and the parallelism between the two guideways is aligned by the measuring method with a ruler gauge; (3) a vertical guideway is fixed by the method in the step (1) and the verticality between the vertical guideway and the guideways in the steps (1) and (2) is aligned by the measuring method with a vertical gauge. The method greatly reduces the requirement on the machining accuracy of the machine tool body, solves the double difficulties brought about by machine tool body machining and installation and has realistic positive meaning.
Description
Technical field
The present invention relates to a kind of installation method of guide rail, be specifically related to a kind of guide rail is installed on the method for lathe, belong to the mechanical device technical field.
Background technology
At present, the horizontal Machining centers lathe of domestic production mostly is positive T type or inverted T shape structure greatly, bed piece is the monoblock cast structure, and lathe bed is provided with X-axis and Z axis rail installed surface, and is provided with corresponding datum level, in order to guarantee follow-up machining accuracy, require two guide rails on X-axis or the Z axle installed surface to be parallel to each other, and X-axis is vertical mutually with guide rail on the Z axle, and linearity is not higher than 0.008mm/1000mm, flatness is not higher than 0.005mm/500mm, and perpendicularity is not higher than 0.01mm/1000mm.Because bed piece processes at one time, so its requirement on machining accuracy is very high, used equipment generally by external import, costs an arm and a leg, thereby cost is higher.
On the other hand, the installation method of existing guide rail is referring to shown in the accompanying drawing 1～2, when mounting guide rail 1, guide rail one side is close proximity on the datum level 3 of bed piece 2, opposite side is provided with voussoir 5, and the vertical precision of guide rail mainly relies on datum level to guarantee, and further adjusts by voussoir; And the depth of parallelism between the guide rail and perpendicularity are so long as rely on the machining accuracy of bed piece to guarantee.Therefore, above-mentioned installation method relies on very high to the machining accuracy of bed piece, in case that lathe bed adds man-hour is wrong poor, promptly can cause the difficulty of each link when installing, and is difficult to reach the requirement of guide rail installation accuracy.In addition, when utilizing voussoir to adjust, can cause the flexural deformation of guide rail linearity, and the retentivity of precision is relatively poor, further improved needs are arranged.
Summary of the invention
The installation method that the purpose of this invention is to provide a kind of machine tool guideway reduces the requirement to the bed piece machining accuracy when guaranteeing the guide rail installation accuracy.
To achieve the above object of the invention, the technical solution used in the present invention is: a kind of installation method of machine tool guideway comprises the steps:
(1) shovel on bed piece and scrape preparing an installed surface that cooperates with the guide rail bottom surface, described installed surface is 3～5mm near the distance of one side of lathe datum level and datum level, and the flatness of described installed surface is less than 0.004mm/500mm; Again guide rail is pressed on the described installed surface and with bed piece and fixedlys connected;
(2) adopt the method for step (1) to fix second parallel guide rail, the depth of parallelism is between the two drawn the table centering by the ruler cubing;
(3) the method fixed vertical guide rail of employing step (1), the perpendicularity between this vertical guide rail and step (1), (2) described guide rail is drawn the table centering by vertical cubing.
Above, it is prior art that described shovel is scraped step, and purpose is in order to prepare the high installed surface of flatness; Owing to reach certain flatness, thereby can guarantee to fix the vertical precision of the guide rail on it.And the installation of follow-up guide rail also is to adopt in the same way, and the depth of parallelism between each guide rail, perpendicularity are drawn the table centering by cubing respectively; Thereby the whole erection process is not high to the requirement on machining accuracy of bed piece, greatly reduces cost.The described vertical guide rail of step (3) is for the guide rail in step (1), (2), in the actual installation process, the X-axis guide rail can be installed earlier, also the Z axis rail can be installed earlier; And step (2) and step (3) also can be exchanged, and be promptly unqualified to erection sequence.
Further technical scheme after the guide rail of completing steps (1) is installed, is injected guide rail glue between guide rail and lathe datum level.To its objective is and to keep datum clamp face in order keeping in repair.
Because the employing of technique scheme, compared with prior art, the present invention has following advantage:
1. the present invention utilizes the shovel mode of scraping directly to prepare installed surface on bed piece, when having saved guide rail and having installed to the dependence of lathe bed datum level, thereby greatly reduce requirement to the bed piece machining accuracy, not only reduced cost, and changed installation method in the past, reduce installation difficulty, solved lathe bed processing and a dual difficult problem of bringing is installed, had the positive effect of reality.
2. the present invention adopts the method for the stretching centering of cubing to guarantee the depth of parallelism and perpendicularity between the guide rail, and its installation accuracy is guaranteed, and experiment also proof has good effect.
3. installation method of the present invention is simple, is easy to realize, and has good effect, is suitable for applying.

Embodiment one
Shown in accompanying drawing 3～5, a kind of installation method of machine tool guideway comprises the steps:
(1) 2 shovel and scrape preparing an installed surface that cooperates with guide rail 1 bottom surface on bed piece, described installed surface is 4mm near the distance of one side of lathe datum level and datum level, and the flatness of described installed surface is 0.003mm/500mm; Again guide rail is pressed on the described installed surface and with bed piece and fixedlys connected;
(2) adopt the method for step (1) to fix second parallel guide rail, the depth of parallelism is between the two drawn the table centering by the ruler cubing;
(3) the method fixed vertical guide rail of employing step (1), the perpendicularity between this vertical guide rail and step (1), (2) described guide rail is drawn the table centering by vertical cubing.
After the guide rail of completing steps (1) is installed, between guide rail and lathe datum level, inject guide rail glue 4.
Above, it is prior art that described shovel is scraped step, and purpose is in order to prepare the high installed surface of flatness; Owing to reach certain flatness, thereby can guarantee to fix the vertical precision of the guide rail on it.And the installation of follow-up guide rail also is to adopt in the same way, and the depth of parallelism between each guide rail, perpendicularity are drawn the table centering by cubing respectively; Thereby the whole erection process is not high to the requirement on machining accuracy of bed piece, greatly reduces cost.The described vertical guide rail of step (3) is for the guide rail in step (1), (2), in the actual installation process, the X-axis guide rail can be installed earlier, also the Z axis rail can be installed earlier; And step (2) and step (3) also can be exchanged, and be promptly unqualified to erection sequence.
