Description
Technical field
The utility model relates to printed wiring board drilling and milling machine, particularly a kind of bull printed wiring board drilling and milling machine large scale workbench structure.
Background technology
Bull printed wiring board drilling and milling machine is many because of station, and need configuration large scale workbench, as PCB6 head machine, its workbench length reaches 3500mm.As adopted large scale aluminium sheet structure, then light weight but deflection are large, and workbench varies with temperature change in size greatly and affect precision.As used granite slab structure, although do not have the problem of distortion and precision, weight is too large, and workbench difficulty of processing is large, and needs the feeding transmission system configuring more large gauge, and this can increase the production cost of lathe undoubtedly.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of bull printed wiring board drilling and milling machine large scale workbench structure, effectively to solve workbench problem on deformation, guarantees machine finish, and makes its lighting.
It is as follows that the utility model solves the technical scheme that its technical problem adopts:
Bull printed wiring board drilling and milling machine large scale workbench structure of the present utility model, is characterized in that it comprises: granite bracing beam, is horizontally arranged at interval along workbench; Workbench granite joint cover, is positioned at the middle part of workbench, is fixedly connected on the bottom surface of each granite bracing beam; Unit aluminium sheet, on the end face of granite bracing beam, longitudinally interval is fixedly installed, or class interval is fixedly installed; Aluminium matter guide rail slide block connecting plate, longitudinal separation is arranged at bottom workbench, is fixedly connected with each granite bracing beam or workbench granite joint cover.
The beneficial effects of the utility model are, formed the basic framework of workbench, alleviate the weight of workbench significantly with granite bracing beam, workbench granite joint cover; Be fixedly installed using longitudinal separation or unit aluminium sheet that class interval is fixedly installed as table surface, thermal expansion, the stress of each unit aluminium sheet do not superpose, and the setting of workbench granite joint cover can improve the rigidity of workbench, the thermal coefficient of expansion of granite bracing beam, workbench granite joint cover is consistent with the lathe bed under it, therefore can guarantee the machining accuracy of lathe; Reduce the difficulty of processing of each component of workbench, be conducive to reducing its manufacturing cost.
Accompanying drawing explanation
This description comprises following three width accompanying drawings:
Fig. 1 is the front view of the utility model bull printed wiring board drilling and milling machine large scale workbench structure;
Fig. 2 is the sectional elevation of the utility model bull printed wiring board drilling and milling machine large scale workbench structure;
Fig. 3 is the top view of the utility model bull printed wiring board drilling and milling machine large scale workbench structure.
Component shown in figure and corresponding mark: unit aluminium sheet 1, granite bracing beam 2, aluminium matter guide rail slide block connecting plate 3, workbench granite joint cover 4.
Detailed description of the invention
Below in conjunction with drawings and Examples, the utility model is further illustrated.
With reference to Fig. 1, Fig. 2 and Fig. 3, bull printed wiring board drilling and milling machine large scale workbench structure of the present utility model comprises: granite bracing beam 2, is horizontally arranged at interval along workbench; Workbench granite joint cover 4, is positioned at the middle part of workbench, is fixedly connected on the bottom surface of each granite bracing beam 2; Unit aluminium sheet 1, on the end face of granite bracing beam 2, longitudinally interval is fixedly installed, or class interval is fixedly installed; Aluminium matter guide rail slide block connecting plate 3, longitudinal separation is arranged at bottom workbench, is fixedly connected with each granite bracing beam 2 or workbench granite joint cover 4.Formed the basic framework of workbench with granite bracing beam 2, workbench granite joint cover 4, alleviated the weight of workbench significantly.Be fixedly installed using longitudinal separation or unit aluminium sheet 1 that class interval is fixedly installed as table surface; thermal expansion, the stress of each unit aluminium sheet 1 do not superpose; and the setting of workbench granite joint cover 4 can improve the rigidity of workbench; the thermal coefficient of expansion of granite bracing beam 2, workbench granite joint cover 4 is consistent with the lathe bed under it, therefore can guarantee the machining accuracy of lathe.Reduce the difficulty of processing of each component of workbench, be conducive to reducing its manufacturing cost.
For farthest reducing workbench weight, described workbench granite joint cover 4 adopts engraved structure at the noncontact position with each granite bracing beam 2.
Usually, described workbench granite joint cover 4 is fixedly connected with each granite bracing beam 2 by bolt, described unit aluminium sheet 1 is fixedly connected with each granite bracing beam 2 by bolt, and described aluminium matter guide rail slide block connecting plate 3 is fixedly connected with each granite bracing beam 2 or workbench granite joint cover 4 by bolt.
The above principle more of the present utility model that just explain through diagrams, be not the utility model to be confined to shown in and in described concrete structure and the scope of application, therefore every corresponding modify of being likely utilized and equivalent, all belong to the scope of the claims that the utility model is applied for.
