Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0026] Example:

[0027] like Figure 1-6As shown, the embodiment of the present invention provides a CNC fixture system for a CNC machine tool, including a base 1 and a clamping block 25. An active cavity 2 is arranged inside the base 1. A rotating motor 3 and a column 5 are fixedly connected to the bottom of the active cavity 2, and the column 5 is symmetrically arranged on the left and right sides of the rotating motor 3. The rotating motor 3 is mainly used to control the rotation of the driving gear 4. The driving gear 4 rotates while controlling the rotation of the driven gear 8, thereby controlling the rotating table 10 to drive multiple vertical plates 11 to rotate, and replacing the positions of multiple clamping blocks 25. This process does not require the clamping blocks 25 to be disassembled, which is beneficial to improving the processing efficiency of parts. The output shaft of the rotating motor 3 is fixedly connected to the driving gear 4, and the top of the column 5 is fixedly connected to the first electric cylinder 6, and The first electric cylinder 6 is located above the base 1. The first electric cylinder 6 is mainly used to control the movement of the push block 7, so that the push block 7 passes through the through hole 23, and pushes the mounting plate 16 to drive the clamping block 25 to move, so as to clamp and fix the mechanical parts on the placement table 19. The movable end of the first electric cylinder 6 is fixedly connected with the push block 7. The circumferential surface of the column 5 is rotatably connected with the driven gear 8 through a ball bearing. The top of the movable cavity 2 is provided with a rotating hole 9. The top of the driven gear 8 is fixedly connected with a rotating table 10, and the rotating table 10 is rotatably connected inside the rotating hole 9. The top of the rotating table 10 is fixedly connected with a plurality of vertical plates 11. The plurality of vertical plates 11 are distributed in a circular array around the central axis of the rotating table 10. By providing a plurality of vertical plates 11, it is convenient to A plurality of clamping blocks 25 of different types are installed. A through hole 23 is provided inside the vertical plate 11. The through hole 23 and the push block 7 are arranged at the same height. The arrangement of the through hole 23 facilitates the first electric cylinder 6 to control the push block 7 to pass through the through hole 23 and control the clamping block 25 to clamp and fix the mechanical parts. A support tube 12 is fixedly connected to the side of the vertical plate 11 away from the column 5. A sliding groove 13 is provided inside the support tube 12. The sliding groove 13 is internally slidably connected to a limiting block 14. A limiting rod 15 is fixedly connected to the side of the limiting block 14 away from the column 5. The arrangement of the support tube 12, the sliding groove 13, the limiting block 14 and the limiting rod 15 are mainly used for limiting the mounting plate 16, so that the push block 7 can control the mounting plate 16 to move smoothly. The limiting rod 15 is far away from the column 5. One end of the limit block 14 is fixedly connected with a mounting plate 16, and the mounting plate 16 is located on the outside of the support tube 12. The mounting plate 16 is mainly used for the installation of the clamping block 25. The bottom of the clamping block 25 after installation is higher than the top of the placement table 19, which is convenient for the clamping block 25 to clamp and fix the mechanical parts on the placement table 19. A return spring 17 is sleeved on the circumferential surface of the limit rod 15, and the return spring 17 is located inside the sliding groove 13. When the clamping block 25 clamps and fixes the mechanical parts on the placement table 19, the return spring 17 is in a compressed state. Therefore, when the push block 7 releases the mounting plate 16, the elastic force of the return spring 17 is used to control the limit block 14 to drive the limit rod 15 to move, thereby restoring the mounting plate 16 to its initial position.

[0028] A plurality of first mounting holes 18 are arranged inside the mounting plate 16, a connecting plate 24 is fixedly connected to the rear side wall of the clamping block 25, a plurality of second mounting holes 26 are arranged inside the connecting plate 24, and the connecting plate 24 is fixedly connected to the mounting plate 16 through the first mounting holes 18, the second mounting holes 26, and the fastening bolts; a placing table 19 and a second electric cylinder 20 are fixedly connected to the top of the base 1, and the second electric cylinder 20 is symmetrically arranged on the left and right sides of the placing table 19, the second electric cylinder 20 is mainly used to control the movement of the clamping block 21, and the clamping block 21 is inserted into the inside of the clamping groove 22, so as to fix the rotating table 10 to prevent the rotating table 10 from rotating during the CNC lathe processing of mechanical parts, the movable end of the second electric cylinder 20 is fixedly connected to the clamping block 21, a plurality of clamping grooves 22 are arranged on the circumferential surface of the rotating table 10, and the clamping grooves 22 are arranged corresponding to the vertical plate 11.

[0029] An inspection door 27 is fixedly connected to the front side wall of the base 1 by fastening screws, so that the staff can perform maintenance on the equipment inside the activity chamber 2 at a later stage.

[0030] The driving gear 4 is meshed with the driven gear 8, and the rotating table 10 is rotatably connected to the column 5. Four support tubes 12 are arranged on each vertical plate 11 and are evenly distributed between the vertical plate 11 and the mounting plate 16. The limit rod 15 is slidably connected to the support tube 12. The first mounting hole 18 and the second mounting hole 26 are arranged correspondingly. The clamping block 21 and the clamping slot 22 are used in conjunction with the rotating motor 3, the first electric cylinder 6 and the second electric cylinder 20 are all electrically connected to the external controller. The rotating motor 3 rotates at the same angle each time and just moves the vertical plate 11 between the push block 7 and the placement table 19. It should be noted that the clamping blocks 25 on the vertical plates 11 on both sides of the placement table 19 need to be set accordingly during installation to ensure that the clamping blocks 25 on both sides of the placement table 19 are the same type of clamping blocks 25 when clamped.

[0031] Working principle: When in use, the staff first places the parts to be processed on the placement table 19, and then selects the appropriate clamping block 25 according to the model of the parts, and controls the driving gear 4 to rotate by rotating the electric motor 3. While the driving gear 4 rotates, the driven gear 8 is controlled to rotate, thereby controlling the rotating table 10 to drive multiple vertical plates 11 to rotate, and the required model of the clamping block 25 is rotated between the push block 7 and the placement table 19, and then the second electric cylinder 20 controls the movement of the clamping block 21, and inserts the clamping block 21 into the inside of the clamping slot 22, thereby fixing the rotating table 10, and then the first electric cylinder 6 controls the movement of the push block 7, so that the push block 7 passes through the through hole 23, and pushes the mounting plate 16 to drive the clamping block 25 to move, thereby clamping and fixing the mechanical parts on the placement table 19, and when the mechanical parts are processed, the first electric cylinder 6 controls the push block 7 to return to its initial position, and at the same time the reset spring 17 controls the limit block 14 to drive the limit rod 15 to move, thereby restoring the mounting plate 16 to its initial position.

[0032] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
