Description
Technical field
The utility model relates to a kind of Metal Cutting Machine Tool, particularly a kind of improved structure of vertical processing machine tool.
Background technology
At present, in the technical field of Metal Cutting Machine Tool, the vertical processing machine tool that vertical knee-type milling machine, drilling and milling machine, vertical vertical boring and turning mill, vertical machining centre etc. are most widely used, its structure is normally: an affixed vertical rigid posts connects machining cell and utilizes at fuselage and can carry out cross table that X-direction motion and Y-direction move and realize machining to workpiece as fuselage on pedestal; But the trend that day by day maximizes along with the higher level development of world's lathe industry and industrial products, the vertical processing machine tool of this traditional structure has not satisfied needed processing technology and requirement, what world today's non-renewable resources were in an emergency in addition must face the problems, and existing vertical processing machine tool has following weak point:
1. the big and rigidity impetus weakness of lathe weight and volume: be fixed in rigid posts on the pedestal because employing only depends on the bottom surface, machining cell single face again is connected in the go forward agent structure of the power of stretching of rigid posts, the mutual athletic meeting of cutter and workpiece produces upwards and impulsive force and the resistance of horizontal all directions when machining, these powerful active force parts can and be eliminated by parts such as cross table buffering, all the other most of meetings are amplified with lever principle by machining cell and are applied on the rigid posts, so structures shape rigid posts need have enough big rigidity and stability just to be enough to tackle the requirement on machining accuracy that these powerful active forces guarantee lathe, existing vertical processing machine tool all is to realize that by area of section and the weight that strengthens rigid posts this just must cause the significantly increase of lathe weight and volume usually; But structures shape rigid posts only by a bottom surface and pedestal is affixed, machining cell protracts to be puted forth effort unfavorable factor, no matter how to strengthen rigidity and the volume of its structure, lever principle still exists and is constantly acting on, so this structure is in the waste resource, its rigidity impetus weakness is one of main inferior position.
2. the lathe space is big but processing space is little: each parts that rigidity is powerful cause the lathe overall space bigger, this structure has also determined a drawback, just spindle centerline to this reasons in structure of column guide pass distance causes ubiquitous mortality restriction, it has directly determined the lathe Y-direction effectively to process travel limits in this narrow range, the Y-direction of existing vertical processing machine tool effectively process the most not enough lathe integral width of stroke 1/4th in addition littler, cause it lower to the lathe utilization of space, require the big workpiece of width dimensions to process to processing technology.
3. processing technology difficulty and manufacturing cost height: because each component weight and volume are bigger, each kinematic pair adopts prismatic surface guideway and the parts of thick and heavy dovetail slideway face, rectangular guideway face various again usually, the big consequence of accumulated error appears easily, need carry out fine finishining and the bigger scraping of labour intensity operates to reach every required precision to it, cause each component processing method difficulty, its manufacturing of expense material of wasting time and energy is to such an extent as to cause the high inferior position of waste manufacturing cost of material and resource.
4. transportation and mobile very inconvenient: because volume and deadweight are excessive, transportation and mobile very inconvenient, and in the loading and unloading moving process, have bigger potential safety hazard.
