[0020] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the scope of protection of the present utility model.

[0021] Refer to Figures 1 - 3, a precise positioning device for efficient cutting of metal castings, including a workbench 1, a support frame 3 is fixed on the top of the workbench 1, and a cross bar 4 is installed on the inner side of the support frame 3, a sleeve frame 5 is sleeved on the outer side of the cross bar 4, and a roller 6 is installed on the inner side of the sleeve frame 5, and a groove body matching the roller 6 is opened on the top of the cross bar 4. By setting the groove body, it can limit the moving direction of the roller 6 and is not easy to separate from the cross bar 4. The middle part of the roller 6 is connected with a rotating shaft 8, and the other end of the rotating shaft 8 is connected to a first servo motor 9. A movable rod group 10 is installed between the sleeve frames 5, and the movable rod group 10 is connected to the sleeve frame 5 through a connecting shaft 16. The outer side of the movable rod group 10 is sleeved with a movable frame 11, and a connecting block 12 is fixed on one side of the movable frame 11. The inner side of the connecting block 12 is threadedly connected to a threaded rod 13, and one end of the threaded rod 13 is connected to a second servo motor 14. The second servo motor 14 is connected to the movable rod group 10. The movable frame 11 forms a sliding structure with the movable rod group 10 through a ring, and the movable frame 11 forms a transmission structure with the connecting block 12 and the threaded rod 13. The movable frame 11 mainly provides a mounting position for the cutting assembly, and after the second servo motor 14 is started, it drives the threaded rod 13 to rotate, thereby driving the connecting block 12 to perform a threaded operation, and the movable frame 11 connected to the connecting block 12 is restricted by the movable rod group 10, so the connecting block 12 and the movable frame 11 can only move along the parallel line direction of the movable rod group 10, thereby completing the conveying work of the cutting assembly;

[0022] The front and back of the workbench 1 are both provided with scale lines 2. By setting the scale lines 2, it is convenient to know the specific position of the relatively distributed sleeve frame 5 after moving, which is conducive to positioning the cutting position. The bottom of the sleeve frame 5 is connected to a linear light source 7, and a reserved hole 15 is provided on the side of the sleeve frame 5 close to the movable frame 11. After the linear light source 7 is turned on, the emitted cylindrical light can illuminate the specific value of the scale line 2, which is convenient for people to observe. The reserved hole 15 and the rotating shaft 8 are a sleeve structure, and the reserved hole 15 forms an integrated structure with the sleeve frame 5 through the opening. The rotating shaft 8 passes through the reserved hole 15, and one end enters the sleeve frame 5 and is connected to the roller 6, so that after the first servo motor 9 is started, it can drive the rotating shaft 8 to rotate, which is convenient for completing the driving work of the roller 6.

[0023] Working principle: When in use, first, the staff operates through the main control system, which can be set at the bottom of the workbench 1. The main control system makes the first servo motors 9, which are set in two groups, respond to different moving speeds and move to different distances, causing the movable rod group 10 to rotate around the connecting shaft 16 and be in an inclined state. And the movable rod group 10 is above the position where cutting needs to be positioned. Then, start the second servo motor 14, which drives the threaded rod 13 to rotate, thereby driving the connecting block 12 to perform a threading operation. And the movable frame 11 connected to the connecting block 12 is restricted by the movable rod group 10. Therefore, the connecting block 12 and the movable frame 11 can only move along the parallel line direction of the movable rod group 10, thus completing the conveying work of the cutting component pre-mounted on the movable frame 11 and completing the efficient cutting work of the metal casting through the cutting component.

[0024] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution of the present invention and its inventive concept, makes equivalent substitutions or changes, and should be covered within the protection scope of the present invention.
