Embodiment
Below in conjunction with drawings and Examples, the utility model is specifically described.
Figure 1 shows that structural representation of the present utility model.
Figure 2 shows that structural representation right view of the present utility model.
Main body of the present utility model is double lead-screw four column frame vertical structures, comprises base 1 and lower jaw seat 20, and lower jaw seat 20 is bolted on base 1.
Described four columns 9 are fixed on four jiaos of base 1, and the upper end of column 9 is provided with oil cylinder seat 6, forms a fixing stress frame.
Above oil cylinder seat 6, be provided with entablature 8, servo-cylinder 7 is housed in oil cylinder seat 6, and described servo-cylinder 7 is arranged in oil cylinder seat 6, has sphere pole 16 in the piston rod of servo-cylinder 7, sphere pole 16 is connected with sensor 15, and sensor 15 is arranged on the lower plane of entablature 8.
The two ends of described entablature 8 are embedded with nut 13, this nut 13 in entablature 8 only rotatably relatively entablature 8 move up and down.
The interior rhizoid thick stick 14 that is respectively installed with of described nut 13 forms with it revolute pair, and the upper end of leading screw 14 is provided with one and connects arm-tie 10, and leading screw 14 lower ends are connected with upper jaw seat 18 through oil cylinder seat 6.
Four jiaos of described upper jaw seat 18 respectively have a guide wheel 17, can prevent that significantly deflection from appearring in upper jaw seat 18 in moving process.
In described guide wheel 17, there is bearing, contribute to reduce the friction force in motion process.
