[0026] Working principle:

[0027] Rapid clamping and adjustment of workpieces in machine tool production and processing:

[0028] When it is necessary to quickly clamp the machine tool workpiece, place the workpiece on the two base plates 3 and between the two straight plates 8, then connect the power lines of the two first motors 101 to the control panel at the same time, and connect the external power supplies of the two first motors 101 at the same time. The first motor 101 starts and drives the threaded rod 102 to rotate through the bearings in the base plate 3 and on the surface of the frame 6. The rotation of the threaded rod 102 drives the two threaded seats 103 to slide upward in the slideway processed on the inner wall of the frame 6. The two threaded seats 103 slide upward and drive the vertical plate 2 104 to move upward. Such movement can drive the machine tool workpiece quick clamping structure 2 to move upward through the two vertical plates 104 for adjustment. When the two machine tool workpiece quick clamping structures 2 move to the middle of the workpiece, the first motor 101 stops rotating. Since the threaded connection between the threaded rod 102 and the two threaded seats 103 has a self-locking function, movement is avoided when the workpiece is clamped.

[0029] Rapid clamping of workpieces in machine tool production and processing:

[0030] After the two machine tool workpiece quick clamping structures 2 move to the middle of the workpiece, the power lines of the two second motors 202 are connected to the control panel at the same time, and the external power supplies of the two second motors 202 are connected at the same time. The second motors 202 start and drive the stud 203 to rotate through the bearing in the second box body 201. The rotation of the stud 203 drives the two threaded seats 204 to slide toward each other in the slideway processed on the inner wall of the second box body 201. The two threaded seats 204 slide toward each other through the raised cylinder on the surface and the slideway processed on the surface of the square plate 205, driving the square plate 205 to slide to the right in the slideway processed on the inner wall of the second box body 201 through the raised part on the surface (such as Figure 4 ), the square plate 205 slides to the right, driving the two cross bars 7 to slide to the right in the second box body 201, thereby driving the straight plate 8 to move to the right through the two cross bars 7. In this way, the surface of the workpiece can be quickly clamped through the relative movement of the two straight plates 8.
