Description
Technical field
The utility model relates to the head of a kind of gantry machine tool, particularly a kind of gantry machine tool guiding mechanism is installed.
Background technology
At present, on market, the head of common gantry machine tool is installed general laminating rail plate or the two kinds of mounting means of linear rolling track of adopting of guiding mechanism.Laminating rail plate vibration resistance is good, but guide rail operation is gapped, and walking linearity is relatively low.The feature of linear rolling track is that coefficient of friction is low, guide rail operation gapless walking linearity is higher, but due to the characteristic of rolling guide itself has determined its vibration resistance can be poor and the deficiency of rigidity aspect.As shown in Figure 1, relative motion between tradition slide and head adopts merely the planer-type milling machine of linear rolling track, generally can only be used for light cut, in the situation that cutting force is excessive, likely produce vibration, thereby not only can affect the machining accuracy of lathe and the surface quality of workpiece, but also can reduce the durability of production efficiency and cutter, in the service life that even can reduce lathe, the noise that vibration produces also can affect working environment.Along with the development of Numeric Control Technology and Digit Control Machine Tool, guiding mechanism need to be installed and there is higher guiding accuracy, better shock resistance and durability.
Utility model content
Main purpose of the present utility model is the shortcoming that overcomes prior art, provides a kind of guiding accuracy high, and head bearing capacity is strong, good rigidly, and the head of the gantry machine tool that absorbing is good is installed guiding mechanism.
The utility model adopts following technical scheme:
A kind of head of gantry machine tool is installed guiding mechanism, include crossbeam, be movably set in the slide on crossbeam and can be arranged at movably vertically the head on slide, on described slide, be formed with the storage tank of vertical perforation, head is installed in this storage tank, between the storage tank arranged on left and right sides cell wall of the arranged on left and right sides wall of described head and slide, be connected by linear rolling track, between the storage tank rear side cell wall of described head rear wall and slide, be connected by roller slide block.
Further, the described head left and right sides is respectively arranged with one group of linear rolling track, and two groups of linear rolling tracks are symmetrical arranged.
Further, described linear rolling track forms by vertical guide rail with some slide blocks that vertical guide rail is slidably matched.
Further, described vertical guide rail is fixed on storage tank cell wall, and described slide block is fixed on head sidewall.
Further, described vertical guide rail is fixed on head sidewall, and described slide block is fixed on storage tank cell wall.
Further, described roller slide block is fixed on slide by voussoir, and described voussoir and slide are equipped with according to slope.
Further, on the storage tank rear wall of described slide, be symmetrically arranged with two groups of roller slide blocks.
From above-mentioned, to description of the present utility model, compared with prior art, the beneficial effects of the utility model are: as rail-sides to benchmark, can guarantee the walking linearity of machine tool guideway using the linear rolling track that is arranged at head both sides; , coordinate with head by roller slide block is set on slide rear wall meanwhile, can, in ensureing head motion guiding accuracy, improve the bearing capacity of head, and effectively promote the rigidity of head, reduce and add the vibration that produce man-hour.The utility model adopts the compound direction mode of rolling and sliding combination, has the advantages such as frictional force is low, absorbing good, walking linearity is high, good rigidly, and compact conformation, takes up room littlely, simple in structure, is convenient to processing, assembling, adjusts and maintenance.
