Detailed description of the invention
Below in conjunction with the accompanying drawings this utility model is described in further detail.
Seeing Fig. 1-6, this utility model structurally includes the frame being made up of base 1, set frame plate 10 and footstock 6, set
Frame plate 10 centerline in the horizontal direction is provided with screw mandrel 3, and base 1 and footstock 6 are mounted on alignment bearing, and screw mandrel 3 passes through
Alignment bearing is arranged in frame.Screw mandrel 3 lateral symmetry is provided with guide rail 9, by slide block 8 connecting platform frame 5 on guide rail 9, flat
Object stage 4 is fixed on stand 5.The cross section of set frame plate 10 is bow font, and the back of set frame plate 10 is provided with for strengthening both sides firm
The floor of degree.Being provided with motor 11 on base 1, the rotating shaft of motor 11 connects up and drives screw mandrel 3, is fixed with load
