Abstract

The utility model relates to a cross-beam guiding rail assembly of a computerized numerical control (CNC) planer type milling machine. Roller linear guiding rails are mounted both on one horizontal plane and one vertical plane of a cross beam, wherein central connecting lines of the roller linear guiding rails on the two planes are in the same inclined plane, one end of each roller linear guiding rail is fixedly mounted on the cross beam, and the other end of reach roller linear guiding rail is mounted on the cross beam through a pressing-block positioning device. According to the cross-beam guiding rail assembly of the CNC planer type milling machine, the roller linear guiding rails are mounted both on the horizontal plane and the vertical plane of the cross beam, the distance between the roller linear guiding rails is increased, the torsion-resistant section moment is increased, the load-bearing stiffness performance is improved, the roller linear guiding rails are positioned through the pressing-block positioning devices, the straightness of each roller linear guiding rail on the cross beam can be adjusted, installation accuracy can be controlled conveniently, and therefore the installation accuracy of the roller linear guiding rails is improved; and moreover, the friction coefficient of the roller linear guiding rails is low, the kinetic friction coefficient and the static friction coefficient are quite close to each other, a low-speed creeping phenomenon cannot happen easily, the fast feed speed of a gantry machining center is increased, and the accelerating ability of the gantry machining center is improved.

Description

The CNC planer type milling machine beam guideway
Technical field
The utility model relates to machinery assembling manufacturing technology field, specifically, relates to a kind of CNC planer type milling machine beam guideway.
Background technology
The guide rail of tradition CNC planer type milling machine adopts the stiff dough guide rail, sliding friction, and this structure processing and manufacturing cost height, and the coefficient of friction of guide pass is big, is easy to generate wearing and tearing and creeping phenomenon, and driving motor power is big.Existing guide rail structure is rectilinear layout, and the cross slide way great majority are installed at grade, and this structure exists tangible deficiency, and promptly the antitorque moment of crossbeam, slide and rigidity deficiency have caused the heavy cut of CNC planer type milling machine indifferent.
The patent No. is to disclose a kind of CNC planer type milling machine beam guideway structure in 200720148243.5 the utility model patent, the horizontal end face and the perpendicular end surface of crossbeam respectively are provided with line slideway, each guide rail is parallel to each other, and guide rail is fixed on the horizontal end face and perpendicular end surface of crossbeam by screw along horizontal direction.The beam guideway structure of above-mentioned utility model patent can be born on the space two orthogonal gravity and cutting force, the work of supports main shaft assembly stably, still, guide rail is fixed on the crossbeam by screw, the linearity of guide rail on crossbeam can not be regulated, and installation accuracy is poor.
The utility model content
The purpose of this utility model is to creep and the problems referred to above such as heavy cut ability, installation accuracy be low at the unit head that existing CNC planer type milling machine beam guideway exists, and a kind of heavy cut ability, unit head walking precision and high CNC planer type milling machine beam guideway of positioning accuracy that improves CNC planer type milling machine is provided.
The technical solution of the utility model is: a kind of CNC planer type milling machine beam guideway, roller line slideway all is installed on the horizontal plane of crossbeam and the vertical plane, the center connecting line of the roller line slideway on two planes is in same inclined-plane, roller line slideway one end is fixedly mounted on the crossbeam, and the other end is installed on the crossbeam by the briquetting positioner.
Preferably, the briquetting positioner comprises briquetting and is arranged on briquetting screw on the briquetting, briquetting by the briquetting screw with an end location and installation of roller line slideway on crossbeam.
The beneficial effects of the utility model are: roller line slideway all is installed on the horizontal plane of the utility model crossbeam and the vertical plane, strengthened the distance between two guide rails, improved the Torsion Section square, improved the load-bearing rigidity performance, the briquetting stationary positioned is adopted in the location of roller line slideway, can regulate the linearity of guide rail on crossbeam, be convenient to control installation accuracy, improve the installation accuracy of guide rail, and the roller line slideway coefficient of friction is low, static and dynamic friction coefficient is more approaching, is difficult for producing low speed jerking motion, has improved the fast forward speed and the acceleration capacity of gantry machining center.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
The specific embodiment
The utility model is described in further detail below in conjunction with accompanying drawing.
A kind of CNC planer type milling machine beam guideway all is equipped with roller line slideway 2 on the horizontal plane of crossbeam 1 and the vertical plane, static and dynamic friction coefficient is more approaching, is difficult for producing low speed jerking motion, has improved the fast forward speed and the acceleration capacity of gantry machining center.The center connecting line of the roller line slideway 2 on above-mentioned two planes has strengthened the distance between two roller line slideways 2 in same inclined-plane, improved the Torsion Section square, has improved the load-bearing rigidity performance.Roller line slideway 2 one ends are fixedly mounted on the crossbeam 1, and the other end is installed on the crossbeam 1 by the briquetting positioner.
Above-mentioned briquetting positioner comprises briquetting 3 and the briquetting screw 4 that is arranged on the briquetting 3, briquetting 3 by briquetting screw 4 with an end location and installation of roller line slideway 2 on crossbeam 1, tighten and unclamp briquetting screw 4 and can regulate the linearity of roller line slideway 2 on crossbeam 1, be convenient to control installation accuracy, improve installation accuracy.
