Description
Technical field
The utility model relates to several numerical control gantry lathes, is specifically related to a kind of composite guide rail structure of numerical control gantry machine ram.
Background technology
The planer type numerical control lathe of machinery manufacturing industry extensive use at present.Numerous categories such as gantry machine tool is contained and decided beam, moving beam, and move at movable workbench, gantry, overhead crossbeam moves.Side's ram is one of critical component of planer type numerical control lathe, the cutter of machine tooling is the end of the side's of being mounted in ram internal spindle just, so the dynamic property of the whole lathe of whether reasonable directly influence of this structure and the machining accuracy of part, and machining accuracy influences the important key factor of the range of application of lathe just.
The square ram of traditional form is coated on planker inside, pastes the wear-resisting polytetrafluoroethylene of one deck with ram contact-making surface (three faces) and mould thin-skinned band on planker, and the front pressing plate also pastes one deck polytetrafluoroethylene and moulds thin-skinned band.And for square ram, the cross section is generally square, the slider grinder bed grinding of square ram length direction four sides, and the surface accuracy height can be divided into according to product specification: 360mmX360mm, 420mmX420mm, 500mmX500mm waits several different sectional dimensions.During machine tool motion, ram stretches out forward from planker, because ram is a cantilever beam structures, makes bending rigidity relatively poor.Be subjected to the center of gravity variation of main shaft assembly and the influence of ram deadweight and spindle nose Tool in Cutting power, ram overhang branch produces the sag bent distortion from the root to the end, and cause the displacement error and the angular error of main shaft and cutter, and error strengthens along with the increasing of ram overhang.Whole subsides guide-soft-band face has thin oil lubricant at regular time and quantity simultaneously, and formed lubricated face oil film thickness is even more consistent than sliding guidance face became uneven, thereby causes ram to produce gap error on the direction of motion.
Above-mentioned several errors directly influence the positioning accuracy and the machining accuracy of lathe, must be eliminated or limit.
Summary of the invention
The purpose of this utility model provides a kind of composite guide rail structure of avoiding the numerical control gantry machine ram of ram sag bent distortion, and the utility model helps the advantage that reduces to rub simultaneously.
The technical scheme that realizes the utility model purpose is as follows:
The composite guide rail structure of numerical control gantry machine ram, comprise planker and ram in the chute of this planker is set, planker is provided with the ram pressing plate, be equipped with way block on each side wall surface of described ram, be equipped with oriented module on the first side wall face of the chute of described planker and second side wall surface, each oriented module is provided with the first sliding device that rolls that contacts with way block, be equipped with lash adjusting device on the 3rd side wall surface of the chute of planker and the ram pressing plate, this lash adjusting device is provided with the second sliding device that rolls that contacts with way block.
Adopted such scheme, each oriented module is provided with the first sliding device that rolls that contacts with way block, be equipped with lash adjusting device on the 3rd side wall surface of the chute of planker and the ram pressing plate, this lash adjusting device is provided with the second sliding device that rolls that contacts with way block.The existing soft slip that contacts with lash adjusting device on the moving surface of ram gib piece like this has again with sliding and rolls the straight-line rolling that device contacts, and forms compound guide pass under the effect of thin oil lubricant oil film.Therefore, the utlity model has following characteristics:
(1) because the first sliding device of installing that rolls contact with way block face rigidity on the ram with the second sliding device that rolls, reduces, effectively improved the ram sag bent and be out of shape, the assurance machine tool accuracy owing to the lubricating oil film strain.
(2) second sliding roll the pure laminating limit that device and lash adjusting device substituted original ram and slide, the oil film of thin oil lubricant is lower than the second sliding device contact point that rolls simultaneously, effectively avoid pure slip oil film thickness to change the trueness error that causes, so far precision is well guaranteed.
According to said structure, make to the utlity model has following advantage:
(1) sliding rolls device and lash adjusting device by being provided with, make that coefficient of friction is little between quiet ram and the planker, and be beneficial to that to reduce volume little, easy for installation, cause when running up that the frictional force change is little.Its independently at regular time and quantity lubricating system and laminating form the sliding guidance film, and reduce sliding maintenance of rolling device, be beneficial to the bulk life time that prolongs lathe.
(2) installed sliding roll device after, change the friction mode of former sliding friction for sliding and rolling and mutually combine, the power of reducing friction, thereby reduce the power attenuation of motor improves working ability.
(3) by compound guide pass, can reduce turning torque, rapid dynamic response speed, nothing is creeped, and can guarantee that machine tool capability is reliable; In the dynamic property that improves whole lathe, also will improve the machining accuracy of part.
The utility model is described in further detail below in conjunction with the drawings and specific embodiments.
