[0023] To make the objectives, technical solutions, and advantages of this utility model clear and complete, the embodiments of this utility model will be further described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only some, not all, embodiments of this utility model, and are merely used to explain the embodiments of this utility model. They are not intended to limit the embodiments of this utility model. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0024] Example 1: Please refer to Figures 1-5 This utility model provides a technical solution: a machining positioning device for a CNC machine tool, the machining positioning device for the CNC machine tool includes: a fixed base 1, a support platform 2 and a positioning plate 3 are provided on the surface of the fixed base 1, a support frame 4 is provided on the side of the positioning plate 3, an electric push rod 5 is provided on the inner side of the support frame 4, and a base plate 6 is provided at the lifting end of the electric push rod 5.

[0025] The lifting screw 7 has a lifting plate 8 and a moving plate 9 screwed onto its surface. The moving plate 9 has a moving rod 10 inside, and a clamping plate 11 is provided on the end face of the moving rod 10. The clamping plate 11 has a limit screw 12 inside, and an auxiliary plate 13 is provided on the end face of the limit screw 12.

[0026] First, place the workpiece on the surface of the support table 2. Then, use the electric push rod 5 to push the base plate 6, thereby positioning the workpiece with the two sets of clamping plates 11. When it is necessary to position irregular parts, the auxiliary plate 13 can be moved by rotating the limit screw 12. The irregular parts can be positioned by the limit screw 12 in conjunction with the auxiliary plate 13, thereby positioning the parts with the clamping plates 11, which facilitates the subsequent processing of the parts by the CNC machine tool.

[0027] Example 2: Based on Example 1, a clamping plate 11 is provided to facilitate the positioning of irregular parts. The clamping plate 11 has threaded holes on its side, and a limiting screw 12 is screwed into the threaded holes. There are two sets of limiting screws 12, which are symmetrically distributed about the center line of the long side of the surface of the clamping plate 11. An auxiliary plate 13 is fixedly connected to the end face of the limiting screw 12. A support platform 2 is fixedly connected to the surface of the fixed base 1. The support platform 2 has a "T" shaped plate structure. There are two sets of positioning plates 3, which are symmetrically distributed about the fixed base 1. The positioning plates 3 have an overall "U" shaped plate structure. An electric push rod 5 is fixedly connected to the inner side of the support frame 4. A base plate 6 is fixedly connected to the lifting end of the electric push rod 5. A limiting plate 14 is provided on the side of the base plate 6. The limiting plate 14 has an overall "U" shaped plate structure.

[0028] In use, the electric push rod 5 can push the base plate 6 to move, which in turn allows the moving rod 10 to move within the moving plate 9. The displacement of the moving rod 10 can then drive the clamping plate 11 to move, thus positioning the part through the displacement of the two sets of clamping plates 11. When it is necessary to position and process irregular parts, the limiting screw 12 can be rotated, which can then push the limiting screw 12 to move, allowing the auxiliary plate 13 to achieve point positioning of the part, thus facilitating the fixing of irregular parts.

[0029] Example 3: Based on Example 2, a lifting screw 7 is provided to facilitate the positioning of taller parts. A first bearing 15 is provided on the surface of the positioning plate 3. One end of the lifting screw 7 is fixedly connected to the inner ring surface of the first bearing 15. The moving plate 9 is fixedly connected to the surface of the lifting plate 8 by bolts. A sliding groove 16 is provided on the inner side of the positioning plate 3. A slider 17 is provided on the side of the lifting plate 8. The slider 17 has a square plate structure. The slider 17 is inserted into the sliding groove 16 and is slidably connected to the sliding groove 16. A limiting groove 18 is provided on the inner side of the limiting plate 14. A guide plate 19 is provided at one end of the moving rod 10. A guide block 20 is provided on the side of the guide plate 19. The guide block 20 is inserted into the limiting groove 18 and is slidably connected to the limiting groove 18.

[0030] When in use, the lifting screw 7 can be rotated in conjunction with the first bearing 15, thereby allowing the height of the lifting plate 8 to be adjusted. This makes it convenient to use the clamping plate 11 to fix taller parts. The slider 17, in conjunction with the slide groove 16, can prevent the lifting plate 8 from rotating when the lifting screw 7 is rotated. When adjusting the height of the lifting plate 8, the guide block 20 can be displaced within the limiting groove 18, preventing the guide plate 19 from shifting within the limiting plate 14 and improving the stability of the clamping plate 11's displacement.

[0031] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
