[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figures 1-4A valve casting processing and cutting device includes a worktable 1, a bearing assembly, and a cutting assembly. The bearing assembly includes a support plate 2, a support frame 3, a cover 4, a first worm gear 5, a first motor 6, a first worm wheel 7, a second worm gear 8, a second worm wheel 9, a first screw 10, a bearing plate 11, and a pressure plate 12. The upper and lower ends of the support plate 2 are connected to the support frame 3 and the worktable 1, respectively. The support frame 3 is U-shaped, and a lifting groove is provided on the inner wall of the end of the support frame 3 away from its side opening. The cover 4 is provided above the support frame 3, and the first worm gear 5 and the first worm wheel 7 are arranged in the center of the cover 4. The output end of the first motor 6 passes through the cover 4 and is connected to the first worm gear 5 and the first worm wheel 7. A worm gear 5 is connected, and the first worm gear 5 meshes with the first worm wheel 7. The first worm wheel 7 has a second worm gear 8 on both the front and rear sides of its center. The cover 4 also has a second worm wheel 9 that meshes with the second worm gear 8. The lifting groove also has a first screw 10. The first screw 10 passes through the support frame 3 and the cover 4 and is connected to the center of the second worm wheel 9. The side opening end of the support frame 3 is also provided with a bearing plate 11. The pressure plate 12 extends into the lifting groove and is threadedly connected to the first screw 10. The other end of the pressure plate 12 protrudes from the workbench 1 and is adapted to the bearing plate 11. The workbench 1 is also provided with a cutting assembly.

[0025] The outrigger 21 provides stable support for the workbench 1. A support plate 2 is also installed on the workbench 1, which stably supports the support frame 3. The first motor 6, acting as a power source, begins operation. Since the first motor 6 is a servo motor, its speed and direction of rotation can be precisely controlled. The output end of the first motor 6 passes through the cover 4 and connects to the first worm gear 5. Therefore, when the first motor 6 rotates, it drives the first worm gear 5 to rotate synchronously. The first worm gear 5 meshes with the first worm wheel 7. According to the worm gear transmission principle, the rotation of the first worm gear 5 drives the first worm wheel 7 to rotate. The worm gear transmission has a large transmission ratio and self-locking property, enabling stable power transmission and precise control. Second worm gears 8 are installed on both sides of the center of the first worm wheel 7. When the first worm wheel 7 rotates, it drives these two second worm gears 8 to rotate synchronously. Inside the cover 4, the second worm gears 8 mesh with the second worm wheel 9. Therefore, the rotation of the second worm gear 8 further drives the second worm wheel 9 to rotate. A first screw 10 is installed in the lifting groove, its upper part passing through the support frame 3 and the cover 4 and connected to the center of the second worm wheel 9. When the second worm gear 9 rotates, it will drive the first screw 10 to rotate. The pressure plate 12 extends into the lifting groove and is threadedly connected to the first screw 10. According to the principle of threaded transmission, the rotation of the first screw 10 will cause the pressure plate 12 to move up and down in the lifting groove.

[0026] A bearing plate 11 is provided at the side opening end of the support frame 3. As the pressure plate 12 moves downward, the end of it protruding from the worktable 1 will gradually approach the bearing plate 11. When the pressure plate 12 cooperates with the bearing plate 11, it can fix the two ends of the valve casting placed between the two, avoiding the complicated steps of additional stabilization and fixation of the valve body required in the traditional method, making the operation simpler and more efficient.

[0027] The valve ports on the carrier assembly are cut and fixed by cutting the component.

[0028] In this embodiment, the cutting assembly includes a bracket 13 with a downwardly open U-shape, a second motor 14, a second screw 15, a slider 16, a lifter 17, a lifting plate 18, and a cutter 19. The two free ends of the bracket 13 are fixed on the workbench 1. A sliding groove is provided below the top wall of the bracket 13, and the second screw 15 and the slider 16 are disposed in the sliding groove. The slider 16 is threadedly connected to the second screw 15. The upper and lower ends of the lifter 17 are respectively connected to the slider 16 and the lifting plate 18. The cutter 19 is also disposed on the lifting plate 18. The second motor 14 serves as the power source for the horizontal movement of the cutting assembly and is also a servo motor, which can be precisely controlled. The second motor 14 drives the second screw 15 to rotate. The second screw 15 is located in a groove below the top wall of the bracket 13. The slider 16 is threadedly connected to the second screw 15. When the second screw 15 rotates, according to the principle of threaded transmission, the slider 16 moves along the axial direction of the second screw 15 within the groove, thereby adjusting the horizontal position of the cutter 19. The upper and lower ends of the lifting device 17 are connected to the slider 16 and the lifting plate 18, respectively. By controlling the extension and retraction of the lifting device 17, the lifting plate 18 can be moved vertically. Since the cutter 19 is mounted on the lifting plate 18, the vertical movement of the lifting plate 18 will adjust the vertical position of the cutter 19. By controlling the horizontal movement of the slider 16 with the second motor 14 and the vertical movement of the cutter 19 with the lifting device 17, the cutter 19 can be flexibly adjusted to different positions on the valve port, thereby cutting and processing the valve casting.

[0029] The corresponding worm gear and worm shaft are matched to change the installation position of the first motor 6, so as to avoid motion interference between the output end of the cutting component and the fixed first motor 6.

[0030] The reinforcing ribs 20 connected to the support plate 2 on the workbench 1 mainly serve to enhance the strength of the support plate 2. During the operation of the load-bearing assembly, a certain force will be generated on the support plate 2. The reinforcing ribs 20 can disperse these forces, improve the stability and load-bearing capacity of the support plate 2, and ensure the normal operation of the entire load-bearing assembly.

[0031] A waste chip frame 22 with an open waste chip chamber is provided on the workbench 1 to collect waste chips generated during the cutting process. When the cutter 19 cuts the valve casting, the generated waste chips will fall naturally or be cleaned into the waste chip frame 22, preventing the waste chips from scattering everywhere and affecting the cutting equipment, and also facilitating the subsequent centralized processing of waste chips.
