[0038] Embodiment 4

[0039] See also Figure 1 , Figure 2 and Figure 4 The utility model provides a technical solution: a nesting machine tool, including a lifting plate 306, a roller 307 and a pressure sensor 309:

[0040] There are two adjustment frames 302, and the lifting plates 306 are arranged inside the two adjustment frames 302 at the same horizontal height, so that when the rollers 307 on the two lifting plates 306 contact and lift the workpiece at the same time, the workpiece is in a horizontal state.

[0041] Working principle: First, connect the machine tool to the power supply, then hoist the workpiece onto the clamping frame 102 through the external hoisting equipment, and then start the motor connected to the drive rod 308 to drive the drive rod 308 to rotate, so that the two bidirectional screw rods 303 can rotate at the same speed in their respective adjustment frames 302, so that through the rotation of the bidirectional screw rods 303, the two drive blocks 304 can be driven to slide inside the adjustment frame 302, and the curved rod 305 can push the lifting plate 306 to move up and down. When the workpiece contacts the roller 307, the pressure will be transmitted.

Then the nesting rod feed box 201 drives the nesting rod 202 to slide above the slide rail 101. At the same time, the workpiece is clamped and fixed by the clamping frame 102 and driven to rotate. The nesting operation is completed by the contact between the tool head 205 and the workpiece, and the debris generated during the nesting is discharged from the discharge trough 206.
