Patent ID: 7930952

Claim:
A toggle machine tool, comprising: a first toggle positioning platform, comprising: a first platform; a first motor, disposed on the first platform; a first screw rod, wherein the first screw rod is disposed on the first platform and coupled to the first motor for driving the first screw rod to rotate; a second platform, disposed on the first platform, for moving back and forth alternately along a first predetermined path, and a first included angle existing between an extended direction of the first predetermined path and the first screw rod; and a first linkage, disposed between the first platform and the second platform, and connected between the second platform and the first screw rod, wherein the first linkage is driven by the rotation of the first screw rod, such that the second platform is driven to move along the first predetermined path; a second toggle positioning platform, disposed on the first toggle positioning platform, the second toggle positioning platform comprising: a second motor, disposed on the second platform; a second screw rod, wherein the second screw rod is disposed on the second platform and coupled to the second motor for driving the second screw rod to rotate; a third platform, disposed on the second platform, for moving back and forth alternately along a second predetermined path, and a second included angle existing between an extended direction of the second predetermined path and the second screw rod; and a second linkage, disposed between the third platform and the second platform, and connected between the third platform and the second screw rod, wherein the second linkage is driven by the rotation of the second screw rod, such that the third platform is driven to move along the second predetermined path, and a third included angle exists between the second predetermined path and the first predetermined path; a main axle, disposed above the third platform, wherein the main axle is for moving back and forth alternately along a path perpendicular to the third platform; and a third motor, disposed on the first platform; a third screw rod, wherein the third screw rod is disposed on the first platform and coupled to the third motor for driving the third screw rod to rotate; and two third linkages, connected between both sides of the main axle and the third screw linkage, respectively, wherein the third linkages are driven by the rotation of the third screw rod, such that the main axle is driven to move back and forth alternately along a path perpendicular to the third platform.
