[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0021] Example 1, referring to Figure 1-3 A positioning fixture for a CNC machine tool includes a support base 1 and a mounting plate 2, wherein the mounting plate 2 is provided with a dual-position positioning assembly;

[0022] Specifically, the dual-station positioning assembly includes a rotary manipulator, two rotating shafts 3 that are sequentially rotated and mounted on the mounting plate 2, two chuck mounting plates 4 that are sequentially coaxially welded to the outer wall of one end of the two rotating shafts 3, and two three-jaw chucks 5 that are sequentially fixedly mounted on the side walls of the two chuck mounting plates 4.

[0023] Furthermore, the rotary manipulator includes a protective cover 6 fixedly connected to the outer wall of one side of the mounting plate 2, a drive motor 7 fixedly installed on the middle outer wall of one side of the protective cover 6, a double-groove synchronous wheel 8 fixedly mounted on the output shaft of the drive motor 7, and two single-groove synchronous wheels 9 fixedly mounted on two rotating shafts 3 in sequence.

[0024] Furthermore, the output shaft of the drive motor 7 passes through one side of the protective cover 6, and the double-groove synchronous pulley 8 is connected to the two single-groove synchronous pulleys 9 in sequence through two synchronous belts 10. The double-groove synchronous pulley 8 and the two single-groove synchronous pulleys 9 are all located inside the protective cover 6.

[0025] The working principle of this embodiment is as follows: Two three-jaw chucks 5 can be used to position two workpieces simultaneously. The double-groove synchronous pulleys 8 are rotated by the drive motor 7. Then, under the synchronous transmission effect of the two synchronous belts 10, the two single-groove synchronous pulleys 9 will drive the two chuck mounting plates 4 fixed at one end of the two rotating shafts 3 to rotate synchronously. Thus, the two workpieces positioned on the two three-jaw chucks 5 can be rotated and processed synchronously, which helps to improve the processing efficiency of subsequent workpieces. Moreover, with the synchronous linkage effect of the rotation controller, the number of drive motors 7 deployed is reduced, which helps to reduce the cost of use.

[0026] Example 2, refer to Figure 2-4 This embodiment is an optimization based on embodiment 1. Specifically, the support base 1 is provided with an angle adjustment assembly, which includes an angle adjustment shaft 11 rotatably mounted on one side of the support base 1, a fixing cover 12 fixedly connected to the outer wall of one side of the support base 1, a stepper motor 13 fixedly mounted on the outer wall of one side of the fixing cover 12, a worm gear 14 fixedly mounted on the output shaft of the stepper motor 13, and a worm wheel 15 fixedly mounted on one end of the angle adjustment shaft 11.

[0027] Furthermore, the worm 14 and worm wheel 15 mesh with each other and are both located inside the fixed cover 12. The self-locking performance of the meshing of the worm 14 and worm wheel 15 can ensure the stability of the mounting plate 2 during the angle adjustment process. The output shaft of the stepper motor 13 passes through one side of the fixed cover 12, and the outer wall of the other end of the angle adjustment shaft 11 is welded to one side of the outer wall of the mounting plate 2.

[0028] Furthermore, a balance shaft 16 is welded to the outer wall of the other side of the mounting plate 2. One end of the balance shaft 16 is connected to the inner wall of the other side of the support base 1 through a bearing. The balance effect of the balance shaft 16 can ensure the stability of the mounting plate 2 when it rotates.

[0029] The working principle of this embodiment is as follows: the stepper motor 13 controls the worm gear 14 to rotate, and then the worm wheel 15 meshing with the worm gear 14 will drive the angle adjustment shaft 11 to rotate. As a result, the two three-jaw chucks 5 on the mounting plate 2 can tilt upward at a certain angle, so as to facilitate the flexible adjustment of the workpiece processing angle to better meet the use requirements of CNC machine tools.
