[0040] The working principle of the utility model is: Figure 1-Figure 7As shown, the passive wooden window double-end composite precision milling single power source inner frame positioning device of the utility model includes a driving device 1 and a flipping and clamping device 2. The driving device 1 has a rigid spring 16, which can work together with the cylinder 11. The flipping and clamping device 2 can be rotated by using the L-shaped bearing seat 25 and the flip shaft 23 on the lever base 22. The vertical roller 262 and the guide rail slider (the guide rail slider includes a flange opening slider 265 and a guide shaft 264) constitute a sliding assembly to realize the forward and backward movement of the roller. Through the rigid spring 16 in the driving device 1, the long rod 21 with a slide groove in the flipping and clamping device 2 and the dead gear, the step-by-step flipping and clamping actions driven by a single power source (cylinder 11) can be realized to complete the wooden window inner frame positioning task.

[0041] The machine tools on both sides are symmetrical in structure and operate in the same manner. Before the machine tools on both sides and the passive wooden window enter the positioning area, the lever base 22 abuts against the ramp dead stop 241, the rigid spring 16 is compressed, the sliding assembly 26 is at the farthest distance that can be reached, and the vertical roller 262 in the sliding assembly 26 is in a fully raised state;

[0042] When the passive wooden windows of the machine tools on both sides enter the positioning area, since the force applied by the cylinder 11 and the rigid spring 16 to the lever base 22 is large enough, when the piston rod of the cylinder 11 is retracted, the deformation of the rigid spring 16 gradually decreases, and the lever base 22 does not flip. At this time, the four-link 12 drives the sliding assembly 26 to move inward through the long rod 21. When the rigid spring 16 reaches the zero deformation state, the piston rod of the cylinder 11 continues to be retracted. At this time, the force is small, and the rigid spring 16 is equivalent to a rod. Only the lever base 22 performs a flipping action until it reaches the flat dead stop 242. During the flipping process, the slide groove in the long rod 21 slides relative to the shaft pin bolt B 27, and the flange opening slider 265 and the guide shaft 264 are relatively stationary, ensuring that the vertical roller 262 will not interfere with the passive wooden window during the descent process.

[0043] After the vertical roller 262 falls, the piston rod of the cylinder 11 continues to retract. Due to the obstruction of the flat dead stop 242, the lever base 22 will not flip. When the applied force causes the rigid spring 16 to stretch and deform, the four-link 12 produces a corresponding action, and the vertical roller 262 on the sliding assembly 26 is driven by the long rod 21 to move inward along the guide shaft 264 along the flange opening slider 265, and finally the passive wooden window inner frames on both sides are pressed and positioned;

[0044] When the passive wooden window leaves the positioning area, the piston rod of the cylinder 11 first extends outward, the vertical roller 262 gradually moves outward, and the rigid spring 16 gradually relaxes to a zero deformation state, and then the piston rod of the cylinder 11 continues to extend outward. Since the rigid spring 16 will not deform when it does not bear enough force, it is equivalent to a rod, so the lever base 22 will rotate around the flip axis 23 and the four-link 12 will not move;

[0045] When the lever base 22 is against the slope dead stop 241, the piston rod of the cylinder 11 continues to extend outward. The force applied at this time causes the rigid spring 16 to gradually compress and deform, and the four-link 12 changes, pushing the long rod 21, driving the flange opening slider 265 on the connecting plate 261 to move outward along the guide shaft 264 until the vertical roller 262 in the sliding assembly 26 is fully lifted, ensuring that the passive wooden window can move forward normally.

[0046] It is obvious to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the present invention can be implemented in other forms of assembly without departing from the spirit or essential features of the present invention.
