[0009] A second servo motor is installed on the outer surface of the clamping recess, and a bidirectional threaded rod is welded to the output end of the second servo motor. The bidirectional threaded rod is rotatably connected to the inner cavity of the clamping recess, and a clamping plate is threadedly connected to the outer surface of the bidirectional threaded rod, and the clamping plate is slidably connected to the inner surface of the clamping recess. By arranging the second servo motor, the bidirectional threaded rod and the clamping plate, starting the second servo motor can drive the two symmetrically distributed clamping plates to move toward or oppositely through the bidirectional threaded rod, and the two clamping plates moving oppositely can clamp and fix processed objects of different volumes.

[0020] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0021] Reference Figure 1 An adjustable fixture for a CNC machine tool comprises a CNC machine tool body 1, electric guide rails 2 are installed on both sides of the CNC machine tool body 1, the electric guide rails 2 use an external power supply, the top of the electric guide rails 2 is slidably connected to an adjustment block 3, the adjustment block 3 can slide horizontally along the top of the electric guide rails 2, and the connection method between the electric guide rails 2 and the adjustment block 3 is the existing technology. A cylinder 4 is fixedly connected to the top of the inner surface of the adjustment block 3, and a bearing block 5 is fixedly connected to the telescopic end of the cylinder 4. The bearing block 5 is slidably connected to the inner surface side wall of the adjustment block 3. The telescopic movement of the cylinder 4 can drive the bearing block 5 to move up and down, which is convenient for adjusting and controlling the working height of the bearing block 5.

[0022] Reference Figure 1 A first servo motor 6 is installed on the outer surface of the load-bearing block 5. The first servo motor 6 uses an external power supply. A rotating shaft 7 is welded to the output end of the first servo motor 6. The length of the rotating shaft 7 is greater than the length of the load-bearing block 5. The rotating shaft 7 is rotatably connected to the inner cavity of the load-bearing block 5; a hydraulic telescopic rod 8 is welded to the end of the rotating shaft 7 away from the first servo motor 6, and a clamping concave block 9 is installed at the telescopic end of the hydraulic telescopic rod 8. The telescopic movement of the hydraulic telescopic rod 8 can drive the clamping concave block 9 to move horizontally. At the same time, the start of the first servo motor 6 can control the clamping angle of the clamping concave block 9 through the rotating shaft 7 and the hydraulic telescopic rod 8.

[0023] Reference Figure 1-2 A second servo motor 10 is installed on the outer surface of the clamping recess 9. The second servo motor 10 uses an external power supply. A bidirectional threaded rod 11 is welded to the output end of the second servo motor 10. The bidirectional threaded rod 11 is rotatably connected to the inner cavity of the clamping recess 9; a clamping plate 12 is threadedly connected to the outer surface of the bidirectional threaded rod 11. There are two clamping plates 12, and the two clamping plates 12 are symmetrically distributed with the clamping recess 9 as the center; the clamping plate 12 is slidably connected to the inner surface of the clamping recess 9. Starting the second servo motor 10 can drive the bidirectional threaded rod 11 to rotate. Because the thread angles on both sides of the bidirectional threaded rod 11 are opposite, the rotation of the bidirectional threaded rod 11 can drive the two clamping plates 12 to move toward or in the opposite direction. The two clamping plates 12 are forced to move toward each other to clamp and fix the workpiece.

[0024] Reference Figure 1 A load-bearing rod 13 is fixedly connected to the bottom of the electric guide rail 2, and a universal wheel 14 is welded to the bottom end of the load-bearing rod 13. The rolling of the universal wheel 14 can drive the CNC machine tool body 1 and the electric guide rail 2 to move horizontally as a whole, making it convenient for the operator to adjust the working position of the CNC machine tool body 1 according to actual conditions.

[0025] Reference Figure 1 The side of the electric guide rail 2 away from the CNC machine tool body 1 is in contact with a long board 15, the length of the long board 15 is less than the length of the electric guide rail 2, and a warning light 16 is installed on the side of the long board 15 away from the electric guide rail 2. The warning light 16 uses an external power supply, and the warning light 16 can continuously emit dazzling light after being started, so as to quickly warn irrelevant personnel around the CNC machine tool body 1. The outer surface of the electric guide rail 2 is fixedly connected with a support recess 17, and the long board 15 is in contact with the bottom wall of the inner surface of the support recess 17. Two symmetrically distributed support recesses 17 are set on both sides of a single long board 15. The two support recesses 17 on the same side can provide support for the long board 15 and limit the position of the long board 15. When the long board 15 is forced to move upward and completely detached from the inner surface of the support recess 17, the operator can quickly disassemble and replace the long board 15 and the warning light 16 as a whole.

[0026] Reference Figure 1 and Figure 3 A control handle 18 is fixedly connected to the side of the long board 15 away from the electric guide rail 2. The horizontal cross-section of the control handle 18 is U-shaped, and the operator can control the moving direction of the long board 15 by holding the control handle 18. A plurality of anti-slip protrusions 19 are provided on the outer surface of the control handle 18. The plurality of anti-slip protrusions 19 are symmetrically distributed with the control handle 18 as the center. The provision of the anti-slip protrusions 19 can increase the friction force on the surface of the control handle 18, and try to prevent the control handle 18 from accidentally escaping from the operator's control during movement.

[0027] Working principle: First, the operator starts the adjustment block 3 to move horizontally along the top of the electric guide rail 2 according to actual needs, so as to adjust the horizontal position of the clamping block 9. Then the operator starts the cylinder 4 again to drive the load-bearing block 5 to adjust the clamping height of the clamping block 9. The operator can further start the first servo motor 6 to drive the rotating shaft 7 to rotate, and the rotation of the rotating shaft 7 can adjust the clamping angle of the clamping block 9. Then the operator starts the two symmetrically distributed hydraulic telescopic rods 8 again to drive the two clamping blocks 9 to move toward each other. When the two clamping blocks 9 contact the clamped object, the operator starts the second servo motor 10 to drive the two clamping plates 12 in the single clamping block 9 to move toward each other through the bidirectional threaded rod 11. The two clamping plates 12 moving toward each other can quickly clamp and fix workpieces of different volumes.

[0028] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
