[0015] 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.

[0016] The present application will be further described in detail below with reference to all the accompanying drawings.

[0017] Example 1: Reference Figures 1 to 4A polishing machine for thick metal castings includes: a support frame 1, with movable grooves 11 formed around the outer surface of the support frame 1. The movable grooves 11 provide installation and movement space for positioning posts 12, return springs 13, and connecting rods 14, allowing each component to perform corresponding actions within them. The inner surface of the movable grooves 11 is provided with corresponding positioning posts 12, which support and position the return springs 13 and guide the sliding of the connecting rods 14. The outer surface of the positioning posts 12 is fitted with the return springs 13. The return springs 13 provide a restoring force when the connecting rods 14 move up and down due to their elastic deformation. This force, combined with the connecting rods 14, drives the connecting plate 15 and the drum polishing machine 16 to adjust their positions. The upper surface of the return springs 13 abuts against the connecting rods 14. The connecting rods 14 connect the return springs 13 and the connecting plate 15 and can slide on the positioning posts 12, transmitting the elastic force of the return springs 13 to the connecting plate 15. Simultaneously, they are driven by the lower pressure plate 10 to move up and down. The side wall of the connecting rods 14 is fixedly connected to the connecting plate 15, and... Multiple drum polishers 16 are fixedly connected to the lower surface of the connecting plate 15. The connecting plate 15 transmits the force of the connecting rod 14 and the lower pressure plate 10 to the drum polishers 16, causing the drum polishers 16 to move as a whole for polishing the castings. The upper surface of the support frame 1 is fixedly connected to the mounting frame 7, which provides fixed support for the adjusting hydraulic pump 8, so that the adjusting hydraulic pump 8 can be stably installed on the support frame 1. The upper surface of the mounting frame 7 is fixedly connected to the adjusting hydraulic pump 8. The adjusting hydraulic pump 8 is externally equipped with a complete hydraulic system for control, and the output end of the adjusting hydraulic pump 8 is fixedly connected to the adjusting hydraulic rod 9. The adjusting hydraulic pump 8 provides power for the extension and retraction of the adjusting hydraulic rod 9. The adjusting hydraulic rod 9 drives the lower pressure plate 10 to move. The lower surface of the adjusting hydraulic rod 9 is fixedly connected to the lower pressure plate 10, and the lower surface of the lower pressure plate 10 is fixedly connected to the connecting plate 15. The lower pressure plate 10 transmits the thrust or pull of the adjusting hydraulic rod 9 to the connecting plate 15, causing the connecting plate 15 and the drum polishers 16 to move up and down to adjust the polishing position.

[0018] Reference Figure 1 and Figure 4 The interior of the movable groove 11 is connected to the interior of the support frame 1. This connection structure facilitates the connection of the connecting rod 14 through the movable groove 11 and its cooperation with the components inside the support frame 1, ensuring the continuity of the connection of each component. The connecting rod 14 and the outer surface of the positioning column 12 are slidably connected. This slidable connection allows the connecting rod 14 to move along the axis of the positioning column 12, ensuring the stability of the movement direction of the connecting plate 15 and the roller polishing machine 16. The connecting rods 14 are distributed around the connecting plate 15. The connecting rods 14 distributed around the perimeter can support and drive the connecting plate 15 from multiple directions, making the connecting plate 15 subjected to balanced force and moving smoothly. The mounting bracket 7 is located in the middle of the upper surface of the support frame 1. The mounting bracket 7 in the middle position can make the force of the adjusting hydraulic pump 8 and the adjusting hydraulic rod 9 on the lower pressure plate 10 more evenly transmitted to the connecting plate 15, ensuring the stability of the overall structure.

[0019] Reference Figures 1 to 2 The support frame 1 has drive motors 2 fixedly connected to both the front and rear sides of its sidewalls. The drive motors 2 provide power for the rotation of the drive rotating column 3 and are the power source for the chain conveyor belt 5. The output end of the drive motor 2 is fixedly connected to the drive rotating column 3, which transmits the power of the drive motor 2 to the drive rotating roller 4, causing the drive rotating roller 4 to rotate. The drive rotating roller 4 is fixedly connected to the outer surface of the drive rotating column 3 and is located inside the support frame 1. The drive rotating roller 4 drives the chain conveyor belt 5 to rotate, realizing the conveying of castings. A chain conveyor belt 5 is provided between two adjacent drive rotating rollers 4. The chain conveyor belt 5 is used to place and convey thick metal castings to be polished. It works with the drive rotating roller 4 and driven rollers to achieve smooth movement of castings. Multiple driven rollers are rolledly connected to the inner surface of the chain conveyor belt 5. The positions of the multiple driven rollers are parallel to the positions of the drive rotating roller 4. The driven rollers support the chain conveyor belt 5 and work with the drive rotating roller 4 to keep the chain conveyor belt 5 flat, ensuring smooth conveying of castings.

[0020] Reference Figure 4 A hydraulic pump 21 is fixedly connected to both the left and right sides of the outer surface of the support frame 1, and a hydraulic rod 17 is fixedly connected to the output end of the hydraulic pump 21. The hydraulic pump 21 provides power for the extension and retraction of the hydraulic rod 17, which drives the arc-shaped guide plate 20 to move. One end of the hydraulic rod 17 is fixedly connected to the arc-shaped guide plate 20. The arc-shaped guide plate 20 can contact the casting under the push of the hydraulic rod 17, and plays a guiding and limiting role for the casting during transportation, preventing the casting from deviating. Sliding rods 18 are fixedly connected to both the front and rear sides of the side wall of the arc-shaped guide plate 20, and the outer surface of the sliding rods 18 is slidably connected to the support frame 1. The sliding rods 18 guide the arc-shaped guide plate 20 to move. The movement of the guide plate 20 serves as a guide, ensuring that the arc-shaped guide plate 20 moves in a straight line. A clamping spring 19 is sleeved on the outer surface of the sliding rod 18, and the clamping spring 19 abuts against the inner surface of the support frame 1. The clamping spring 19 generates a clamping force on the sliding rod 18 through its own elasticity, which, together with the abutting hydraulic rod 17, keeps the arc-shaped guide plate 20 in stable contact with the casting. One end of the sliding rod 18 is fixedly connected to a limit post 6, and the number of limit posts 6 corresponds to the number of sliding rods 18. The limit posts 6 limit the range of movement of the sliding rod 18, preventing the sliding rod 18 from detaching from the support frame 1 and ensuring the stability of the connection between the sliding rod 18 and the arc-shaped guide plate 20.

[0021] 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.
