Description
Technical field
The utility model relates to a kind of machining equipment, especially a kind of multiway type machining center.
Technical background
Present machining center on the market is substantially all single main axle structure, and it is for the processing in enormous quantities of finding in some, and efficient is relatively low, because only one cutter is participated in processing in the same time.Yet building-block machine although can participate in simultaneously cutting by many main shafts, is raised the efficiency, and its versatility is poor, and adjusts and safeguard also trouble.Chinese patent discloses a kind of gantry Multishaft processing center, and (patent No.: 201120550910.9), though it has adopted many main axle structures, its cutter can not be changed automatically, thereby has retrained productivity.Also have on the market at present some gantry machining centers to adopt two main axle structures, but it can not carry out two spindle synchronous tool changing, thereby affect working (machining) efficiency.
Summary of the invention
The purpose of this utility model be to provide a kind of can automatic many spindle synchronous tool changing, the much higher Spindle Machining Center of working (machining) efficiency.
In order to reach above-mentioned utility model purpose, the technical scheme that the utility model adopts is: this numerical control drilling-milling central body adopts movable beam type gantry machining center framework, and it is mainly by base, mobile gantry frame, workpiece erecting bed, Y-direction slide unit, Z-direction slide unit, main axle unit, composition of the control system; It is characterized in that: the workpiece erecting bed is directly installed on base; At the other end of workpiece erecting bed, and in the stroke of mobile gantry frame, the flat placed type tool magazine is installed; The main axle unit that is provided with automatic tool changer more than three or three is installed on the slide plate of Y-direction or Z-direction slide unit; Its mobile gantry frame, Y-direction slide unit, Z-direction slide unit adopt numerical control servo to drive.
Above-mentioned flat placed type tool magazine refers to the magazine tool structure that the axle center of the cutter placement in tool magazine parallels with the axle center of main shaft.
As further improvement in the technical proposal, described workpiece erecting bed adopts circular index workbench, the preferred two decile circular index workbench of this circular index workbench; This structure can effectively solve in part machined in enormous quantities, the problem of the total working (machining) efficiency of the loading and unloading of part impact, thus significantly enhance productivity.
As further improvement in the technical proposal, between the slide plate of the slide plate of described Z-direction slide unit and Y-direction slide unit, vertical compensating cylinder is installed, thus the smoothness when improving the feeding of Z-direction slide unit; Reduce screw mandrel and motor because of the vertical gravity of main shaft and slide unit plate, and the load that increases.
As further improvement in the technical proposal, described X-direction slide unit can be according to one or more revolution working shafts of condition of work increase in demand, to increase the processing work face.
The beneficial effects of the utility model are: 1. after adopting many main axle structures, have the much knives tool to participate in simultaneously processing in processing, significantly improved production efficiency.2. the tool magazine due to automatic tool changer adopts the flat placed type tool magazine, thereby just can carry out easily the tool changing simultaneously of many main shafts, thereby reduces tool change time.3. tool magazine is arranged on the other end of circular index workbench, and in the stroke of mobile gantry frame, can take full advantage of the accurate positioning function of Y, Z axis, forms three dimension system with the mobile gantry frame and carries out reliable flat placed type automatic tool changer.4. because the workpiece erecting bed adopts the circular index workbench, and adopt the travelling gantry shelf structure, so just can be divided into two table tops to the circular index workbench and use, the first half is first for workpiece loading and unloading, and later half is carried out for the processing of workpiece; After the workpiece on the later half workbench processed, the workpiece of second half workbench loaded and unloaded already, thereby system can carry out rotary table automatically, has reduced thus the lay day of workpiece.
