Gantry movable type multifunctional numerical-control drilling and milling machine

Abstract

A gantry movable type multifunctional numerical-control drilling and milling machine comprises a machine body. Upright columns are slidably supported on the machine body, a crossbeam mechanism is fixedly arranged on the upright columns, an upper drilling and milling mechanism is slidably supported on the crossbeam mechanism, a left machine body is connected with a right machine body by a middle connecting frame, a workbench is fixedly arranged on the connecting frame, the left upright column and the right upright column are respectively slidably supported on the left machine body and the right machine body, the crossbeam mechanism crosses the left upright column and the right upright column and is fixedly arranged on the left upright column and the right upright column, the upper drilling and milling mechanism is slidably supported on the crossbeam mechanism, and a first spindle of the upper drilling and milling mechanism ascends and descends under control of a lifting mechanism and is driven by a first servo motor to rotate; and a lateral drilling and milling mechanism is slidably supported on the left upright column by a moving frame, a second spindle of the lateral drilling and milling mechanism is driven by a second servo motor to rotate, and the lateral drilling and milling mechanism is slidably supported on the moving frame. The gantry movable type multifunctional numerical-control drilling and milling machine has the advantages that lateral surfaces and an upper plane of a part can be simultaneously milled and then are drilled, accordingly, the production efficiency is improved, the labor intensity of workers is reduced, and the machining precision is guaranteed.

Description

technical field [0001] The invention relates to the technical field of numerical control drilling and milling equipment, in particular to a gantry mobile multifunctional numerical control drilling and milling machine capable of simultaneously milling the side surface and the upper plane of a part before drilling. Background technique [0002] For the production of heavy steel, BOX box girder, and the butt joint of slender parts, the processing of the workpiece surface is a necessary process. For example, the processing of the side and upper surface of the girder and the large box needs to be milled before drilling. , In this way, two equipments, gantry planer and drilling machine, are required to be completed. The processing of the side and upper surface is generally processed by gantry planer, and the drilling is processed by workers using a drilling machine. Two equipments are used for processing, and the production cost is high. On the other hand, , The efficiency of the ...

Problems solved by technology

However, in the existing gantry mobile CNC drilling and milling machines, there are usually only vertically installed drilling and milling mechanisms, and there is usually only one set of drilling and milling mechanisms. For such parts, the vertically installed drilling and milling mechanism cannot meet the requirements for simultaneous milling or drilling of the side and upper surfaces of such parts
