Abstract
The utility model relates to a numerical control gantry milling machine which comprises a base seat and a workbench. A first small pillar and a first large pillar are respectively arranged on two sides of the workbench. A first linear guide rail is arranged on the end face of the first small pillar. A second linear guide rail, a rack and a third linear guide rail are sequentially arranged on the end face of the first large pillar. A second small pillar is in sliding connection with the first linear guide rail. A second large pillar is in sliding connection with the second linear guide rail and the third linear guide rail. A beam is connected between the end portion of the second small pillar and the end portion of the second large pillar. The beam is in sliding connection with a ram cutter head. A triangle beam is connected with one side of the beam. A third large pillar is arranged on the triangle beam and slides on the second linear guide rail and the third linear guide rail. The numerical control gantry milling machine has the advantages that the triangle beam is connected on the side of the beam so as to effectively improve rigidity, by adopting design of three pillars and single linear rail and single side transmission, transmission precision of the pillars is improved.

Technical field
The utility model relates to the field of lathe, especially a kind of CNC planer type milling machine.
Background technology
CNC planer type milling machine has the milling machine of portal frame and horizontal long lathe bed.Planer-type milling machine machining accuracy and productivity ratio are all higher, be adapted in batch with a large amount of production in the plane and the inclined-plane of machining large workpiece.But numerical control gantry is processing space curved surface and some special type parts also.Planer-type milling machine constitutes portal frame by column and back timber, and crossbeam can be done elevating movement along two column guide rails.The milling head of 1～2 band vertical major is arranged on the crossbeam, can do transverse movement along beam guideway.Also a milling head that has horizontal spindle can be installed respectively on two columns, it can do elevating movement along the column guide rail.These milling heads can be processed several surfaces simultaneously.Each milling head all has independent motor (the power maximum can reach 150 kilowatts), gear, operating mechanism and spindle unit etc.Add man-hour, workpiece is installed on the workbench and does the length feed motion thereupon.
The CNC planer type milling machine that uses at present; Moving of column all is to adopt the bilateral transmission of two-wire rail, because large-scale planer-type milling machine, when the drive of motor column moves on tooth bar; Cause easily an edge column than another side column move fast or slow, cause transmission accuracy low.
The utility model content
The technical problem that the utility model will solve is: in order to overcome the above-mentioned middle problem that exists, a kind of CNC planer type milling machine is provided, its transmission accuracy height and crossbeam good rigidly.
The utility model solves the technical scheme that its technical problem adopted: a kind of CNC planer type milling machine; Comprise base and be installed in the workbench on the base; Be fixed with first post and first column on the described base; First post and first column are separately positioned on the workbench both sides, and first line slideway is installed on the end face of described first post, second line slideway is installed on the end face of first column successively, is used for the monolateral tooth bar and the 3rd line slideway of transmission; Tooth bar is arranged between second line slideway and the 3rd line slideway; Slidely connect second post on described first line slideway, slidely connect second largest column on second line slideway and the 3rd line slideway, be connected with crossbeam between the end of described second post and the second largest post end; Slidely connect the ram milling head on the crossbeam; Described crossbeam one side is connected with the triangle crossbeam, and the triangle crossbeam is provided with the third-largest column, and the third-largest column slides on second line slideway and the 3rd line slideway.
More steady for column is slided on tooth bar, the width of described second post is less than the width of second largest column.
In order to improve the intensity of crossbeam, described triangle crossbeam and crossbeam shape triangular in shape.
The beneficial effect of the utility model is, the CNC planer type milling machine of the utility model connects the triangle crossbeam in a side of crossbeam, can improve rigidity effectively; Adopt the design of three columns and utilize the monolateral transmission of single line rail, can improve the transmission accuracy of column, its project organization is reasonable, and the tooth bar transmission accuracy is high.
