This structure relatively connects the lifting movable plate 5 and the clamping positioning seat 4 through the U-shaped mounting part 2, so that the lifting movable plate 5 drives the clamping positioning seat 4 to perform lifting and adjustment through the lifting mechanism 3, so that the clamping positioning seat 4 clamps and fixes the workpiece. An integral positioning plate 15 is provided on one side of the groove structure of the U-shaped mounting part 2, and the positioning plate 15 is located on the outside of the U-shaped mounting part 2. This structure allows the grooves on both sides of the U-shaped mounting part 2 to be bent to form the positioning plate 15, so that the rotating shaft mounting seat 14 and the T-shaped limit rod 13 are positioned through the positioning plate 15, and the T-shaped limit rod 13 is penetrated through the positioning plate 15. 3, and the T-shaped limit rod 13 is fixed to the side of the shaft mounting seat 14 through a threaded structure, this structure makes the shaft mounting seat 14 and the T-shaped limit rod 13 relatively firmly connected, and the shaft mounting seat 14 is moved through the cooperation of the T-shaped limit rod 13 and the positioning plate 15, so as to clamp the positioning seat 4 relative to the workpiece and tighten it, thereby improving the tightness of the workpiece clamping. A tightening spring 12 is sleeved on the T-shaped limit rod 13, and the tightening spring 12 is between the shaft mounting seat 14 and the positioning plate 15. This structure enables the shaft mounting seat 14 to push the T-shaped limit rod 13 to move when subjected to external force, and compress the tightening spring 12. Through the rebound force of the tightening spring 12, the shaft mounting seat 14 is relatively tightened, thereby ensuring the stability of the workpiece clamping. The U-shaped mounting part 2 is divided into The clamping and positioning seat 4 is installed with a special clamping connection, and the side of the clamping and positioning seat 4 is integrally provided with a convex structure with an outer arc shape. The clamping and positioning seat 4 is penetrated by a positioning shaft 7, and the positioning shaft 7 and the shaft mounting seat 14 are movably plugged and arranged through a ball structure. When positioning the workpiece, this structure only needs to make the clamping and positioning seat 4 rotate through the rotating mechanism under the positioning of the positioning shaft 7 to realize the movement of the clamping and positioning seat 4, so that the clamping and positioning seat 4 can clamp and position the workpiece through the arc convex structure, and the clamping and positioning seat 4 compresses the fastening spring 12 through the shaft mounting seat 14, and the clamping and positioning seat 4 is fastened relative to the workpiece through the rebound force of the fastening spring 12.

[0020] Working principle: When using the CNC machining center that is easy to clamp quickly, first, when the CNC machining center body 1 processes and positions the workpiece, the workpiece is placed on the processing table 6, so that the workpiece is between the clamping and positioning seats 4, and the clamping and positioning seats 4 are driven to rotate the positioning shaft 7 through the rotating structure, and the shaft mounting seat 14 performs rotational positioning processing on the positioning shaft 7, and the arc-shaped convex part of the clamping and positioning seat 4 is facing one side of the workpiece, and then the lifting mechanism 3 is started, and the lifting movable plate 5 is driven to rise and fall through the screw structure, and the height of the U-shaped mounting part 2 is adjusted to determine the clamping height of the clamping and positioning seat 4 for the workpiece, and then the movable mounting seat 11 is moved under the drive of the horizontal moving mechanism 10, and the clamping and positioning seats 4 on both sides are moved toward the workpiece, so that the workpiece is clamped by the convex parts of the clamping and positioning seats 4, and the clamping and positioning seats 4 When under pressure, the T-shaped limit rod 13 is pushed to move through the rotating shaft mounting seat 14 to compress the fastening spring 12. The clamping and positioning seat 4 clamps the workpiece tightly through the rebound force of the fastening spring 12. The positioning plate 15 is used for the movable limiting processing of the T-shaped limit rod 13. After the workpiece is clamped, the workpiece is processed by the CNC machining center body 1, and the processing table 6 moves relative to the workbench 8 through the movable guide rail 9 to adjust the processing position. After the workpiece is processed, the clamping and positioning seat 4 is rotated again so that the workpiece can be removed from the CNC machining center body 1. Since the position of the clamping and positioning seat 4 is determined, when the workpiece of the same size is processed subsequently, it is only necessary to place the workpiece between the clamping and positioning seats 4, and then the clamping and positioning seat 4 can quickly clamp the workpiece through the arc-shaped protrusion, thereby completing a series of tasks.
