Description
Technical field
The utility model relates to printed wiring board drilling and milling machine, the straight-line guide rail slide block connecting plate of particularly a kind of Absorbable rod linear expansion for bull printed wiring board drilling and milling machine workbench.
Background technology
The workbench of bull printed wiring board (PCB) drilling and milling machine requires large format lightweight, usual employing alloy aluminum material, but lathe bed is with grouan material, the linear expansion coefficient of bi-material differs greatly, the coefficient of expansion of aluminium is that 0.0000226 (l/ ° c), the coefficient of expansion of granite is that 0.0000048 (l/ ° c), and aluminium is 4.7 times of granite material.Large format workbench generally will use 4 line slideways, and workbench is connected with guide rail slide block by cushion block.When serviceability temperature and fitting temperature different time, workbench and lathe bed can produce relative displacement, make the outside line slideway of workbench bear very large swelling stress, and produce displacement, lose guiding accuracy.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of straight-line guide rail slide block connecting plate of Absorbable rod linear expansion, to eliminate the impact of variations in temperature on line slideway guiding accuracy.
It is as follows that the utility model solves the technical scheme that its technical problem adopts:
The straight-line guide rail slide block connecting plate of Absorbable rod linear expansion of the present utility model, it is characterized in that: it comprises the upper plate, the lower plate that parallel, the metallic elastic sheet of the setting paralleled for a pair is arranged at intervals with between upper plate, lower plate, the vertical upper end of metallic elastic sheet is fixedly connected with upper plate, and vertical lower end is fixedly connected with lower plate.
The beneficial effects of the utility model are, connecting plate is arranged between aluminium matter workbench and the guide rail slide block of line slideway, aluminium matter workbench linear expansion stress is absorbed by the metallic elastic sheet on connecting plate, avoid linear expansion stress to directly act on line slideway, therefore effectively can eliminate the impact of variations in temperature on line slideway guiding accuracy.
Accompanying drawing explanation
This description comprises following four width accompanying drawings:
Fig. 1 is the upper configuration mode schematic diagram of straight-line guide rail slide block connecting plate at bull printed wiring board drilling and milling machine of the utility model Absorbable rod linear expansion;

Component shown in figure and corresponding mark: granite lathe bed 10, line slideway 11, aluminium matter workbench 20, guide rail slide block 21, cushion block 22, upper plate 231, lower plate 232, metallic elastic sheet 233.
Detailed description of the invention
Below in conjunction with drawings and Examples, the utility model is further illustrated.
With reference to Fig. 2, the straight-line guide rail slide block connecting plate of Absorbable rod linear expansion of the present utility model comprises the upper plate 231, the lower plate 232 that parallel, the metallic elastic sheet 233 of the setting paralleled for a pair is arranged at intervals with between upper plate 231, lower plate 232, the vertical upper end of metallic elastic sheet 233 is fixedly connected with upper plate 231, and vertical lower end is fixedly connected with lower plate 232.
With reference to Fig. 2 and Fig. 3, described upper plate 231, lower plate 232 have the strip hole of its plate body through, the plate face shape of metallic elastic sheet 233 is cross, and its vertical upper end is welded with upper plate 231 in the strip hole of upper plate 231, and vertical lower end is welded with lower plate 232 in the strip hole of lower plate 232.With reference to Fig. 1, the plate face of described metallic elastic sheet 233 parallels with the vertical median plane of line slideway 11.
Shown in Fig. 1 is a kind of basic configuration mode of the straight-line guide rail slide block connecting plate of Absorbable rod linear expansion of the present utility model.With reference to Fig. 1, granite lathe bed 10 is fixedly fixedly installed two line slideways 11, the guide rail slide block 21 of wherein straight line guide rail 11 is bolted to connection cushion block 22, and aluminium matter workbench 20 is fixedly connected with cushion block 22 by bolt, and this line slideway 11 may be defined as basic rack.The guide rail slide block 21 of another line slideway 11 is fixedly connected with lower plate 232 by bolt, and aluminium matter workbench 20 is fixedly connected with upper plate 231 by bolt.By this, aluminium matter workbench 20 linear expansion stress is absorbed to metallic elastic sheet 33, avoid linear expansion stress to directly act on line slideway 11, effectively eliminate variations in temperature to the impact of line slideway 11 guiding accuracy.
Bull printed wiring board (PCB) drilling and milling machine large format aluminium matter workbench generally to use the line slideway of 4 or greater number, now can will be positioned at a line slideway of centre or close centre as basic rack, and connecting plate of the present utility model is set between the guide rail slide block and aluminium matter workbench of all the other line slideways.
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.
