Abstract
The utility model discloses a kind of high-speed gantry machining center beam structure, comprise cross-beam body and be located at two, cross-beam body upper end closed slide; Described cross-beam body is the rectangular structure of hollow, forms rectangle structure by two elongated crossbeams with the curb girder being connected long beam; Described long beam and described curb girder are lattice-shaped structure.The utility model, by arranging two horizontal guide rails, changes the mounting means of traditional market upper rail, alleviates gravity suffered by crossbeam, improves the performance of beam structure, extends service life; Adopt the utility model install the ram speed of service sooner, more steady.
Description
Technical field
The utility model relates to a kind of high-speed gantry machining center beam structure.
Background technology
In recent years, along with the development of industrial technology, high-speed cutting has become a kind of new machining theory.Traditional numerical control machining center is difficult to the distortion in controlled working and removes large chipping allowance efficiently when processing novel part, the theory such as traditional " heavy cut ", " many bites " is significant discomfort in new parts processing, and the appearance of gantry machining center well solves problems.
Gantry machining center is formed primarily of planer-type milling machine crossbeam, column and workbench, and crossbeam is critical component, directly determines the overall performance of lathe.The structural configuration of crossbeam is to machine tool structure stress and performance, and peak stress, the rigidity of structure, structural stability, shock resistance, structural fatigue degree has material impact.Beam part structure under prior art adopts upper and lower guide rail front to arrange, lathe slide plate and ram weight and cut reaction force and all rely on crossbeam front to bear in this structure, for ensureing crossbeam rigidity and machining accuracy, must increase crossbeam wall thickness and rib quantity, but it can cause crossbeam weight to increase.When the increase of crossbeam weight can make machine tool movement, load value and reversing impact increase, and after crossbeam weight increases, it is affected by gravity can be larger.There will be obvious depending condition when crossbeam is very long, have a strong impact on machining accuracy.In addition in order to shorten the distance of the alignment of shafts to crossbeam, it is very thin that slide plate thickness designs usually, adds and be easily out of shape man-hour, is unfavorable for that the precision of lathe keeps; Add the impact of man-hour due to workpiece self gravitation and cutting force actual, very easily cause the distortion that crossbeam occurs in various degree, affect the machining accuracy of lathe.
Summary of the invention
Goal of the invention: for the deficiencies in the prior art, the utility model provides a kind of high-speed gantry machining center beam structure, operates steadily, speed is fast, effectively alleviate gravity suffered by crossbeam.
Technical scheme: high-speed gantry machining center beam structure described in the utility model, comprises cross-beam body and is located at two, the cross-beam body upper end guide rail be parallel to each other; Described cross-beam body is the rectangular structure of hollow, is made up of with the curb girder being connected long beam two long beams; Described long beam and described curb girder are lattice-shaped structure.By arranging two closed slides, for the guide rail of existing vertical design, the speed of service is faster, and running is more steady, and the pressure suffered by crossbeam is less, reduce impulsive force to crossbeam, effectively extends the service life of whole beam structure; Adopt hollow and lattice-shaped structure, alleviate overall weight to the full extent, effectively cost-saving.
Described guide rail is heavy-load type line slideway, is located at described long beam upper surface and is supported by the streak-like planar of described curb girder top upper process.
The side of described long beam is provided with arc firmware.By lonely shape firmware, long beam is played a supporting role, avoid adopting lattice-shaped structure to bring and bear hypodynamic problem.
The bottom of described long beam and described curb girder junction has row's rectangular recess.Rectangular recess is set, while saving material, plays firm effect.
The lattice-shaped structure of described long beam is evenly distributed rectangular recess.
The described long beam wherein upper end of is provided with ball-screw, and ball-screw is supported by the post block of described curb girder top upper process.By arranging post block and ball-screw, the ram (spindle assemblies) in running can be promoted and screens, improving the stability of running further.
Beneficial effect: compared with prior art, advantage of the present utility model:
1, by arranging two horizontal guide rails, changing the mounting means of traditional market upper rail, alleviating gravity suffered by crossbeam, improve the performance of beam structure, extend service life;
2, adopt the mounting means of horizontal guide rail relative to General guide rail (vertical rail) carry-over moment than large, guide rail runs more steady;
3, adopt the utility model, it is higher, more steady that ram (spindle assemblies) runs (movement) speed;
4, by modified node method, lighter compared to crossbeam, cost is lower.
