DETAILED DESCRIPTION

[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] Reference Figure 1-2, the utility model provides an embodiment: a valve body inner wall polishing device for sealing butterfly valve processing, comprising a workbench 1, the upper surface of the workbench 1 is fixedly connected to a support plate 2, the support plate 2 is fixedly connected to a hydraulic cylinder 3, the output end of the hydraulic cylinder 3 is fixedly connected to a fixed plate 4, a buffer assembly is arranged inside the fixed plate 4, a protective cover 6 is arranged directly below the fixed plate 4, a motor 7 is fixedly connected inside the protective cover 6, and a grinding roller 8 is fixedly connected to the output end of the motor 7; the buffer assembly comprises a limit rod 501, the outer wall of the limit rod 501 is slidably connected to the inner wall of the fixed plate 4, the outer wall of the limit rod 501 is sleeved with a reset spring 502, one end of the reset spring 502 is fixedly connected to the upper surface of the fixed plate 4, and the lower surface of the limit rod 501 is fixedly connected to the upper surface of the protective cover 6;

[0023] Specifically, the structure of the hydraulic cylinder 3 and the support plate 2 provides stable support, ensures the firmness of the workbench 1 during the polishing process, and helps maintain the accuracy and consistency of the processing. The setting of the protective cover 6 effectively prevents debris from splashing, improves operational safety, and protects operators from potential injuries. The device integrates a grinding roller 8 and a motor 7. The motor 7 drives the grinding roller 8 to rotate, thereby achieving polishing of the inner wall of the valve body, making the entire processing process more efficient and integrated. The design of the limit rod 501 and the return spring 502 helps to mitigate the impact force and increase the service life of the entire system. The design is simple and the structure is compact. The cooperation of the motor 7 and the hydraulic cylinder 3 makes the operation more convenient and reduces the complexity of manual operation.

[0024] Reference Figure 2-3 The upper surface of the workbench 1 is fixedly connected with an electric slide rail 9, and the outer wall of the electric slide rail 9 is slidably connected with an electric slider 10; the upper surface of the electric slider 10 is fixedly connected with a fixing plate 11, and the upper surface of the fixing plate 11 is fixedly connected with a stabilizing block 12;

[0025] Specifically, the design of the electric slide rail 9 and the electric slider 10 enables the workbench 1 to move on the stable electric slide rail 9. This provides precise control, helps to maintain stability during the processing, and thus improves the processing accuracy. The connection of the fixed plate 11 to the electric slider 10 allows the fixed plate 11 to be relatively stable as the electric slider 10 moves. This helps to ensure the accuracy of the position and positioning required during the processing. The structure of the electric slide rail 9 and the electric slider 10 provides flexible control of the workbench 1, which can be adjusted according to the processing requirements. This controllability makes it easier to adapt to different processing conditions and workpiece requirements.

[0026] Reference Figure 3A motor 2 13 is fixedly connected to one side of the outer wall of the stabilizing block 12, and a worm 14 is fixedly connected to the output end of the motor 2 13; a fixed shaft 15 is rotatably connected inside the stabilizing block 12, and a worm wheel 16 is fixedly connected to the outer wall of the fixed shaft 15, and the outer wall of the worm wheel 16 is meshed with the outer wall of the worm 14; a connecting rod 17 is fixedly connected to the outer wall of the fixed shaft 15, and a fixed shaft 2 18 is fixedly connected inside the stabilizing block 12, and a connecting rod 2 19 is rotatably connected to the outer wall of the fixed shaft 2 18; a clamping block 20 is rotatably connected to the inner wall of the connecting rod 2 19 on the inner wall of the connecting rod 17;

[0027] Specifically, the worm 14 is connected to the motor 2 13 through the output end, so that the worm wheel 16 can rotate. This design provides a power source for the system movement through the drive of the motor 2 13, and provides stable power for processing. The meshing connection between the worm wheel 16 and the worm 14, as well as the design of the fixed shaft 15 and the fixed shaft 2 18, constitute an effective rotation transmission system. This helps to ensure that the rotational movement of the motor 2 13 can be transmitted to other components, thereby achieving precise control of the workbench 1. The design of the connecting rod 1 17 and the connecting rod 2 19 forms a connecting rod mechanism, so that a coordinated movement is formed between the stabilizing block 12 and the clamping block 20. This helps to ensure that the movement of the stabilizing block 12 affects the clamping block 20, and then affects the movement of the workbench 1, providing more precise and coordinated movements. The clamping block 20 can stably clamp the workpiece or workpiece fixture through the linkage of the connecting rod 1 17 and the connecting rod 2 19. This ensures the firm clamping of the workpiece during the processing, thereby improving the processing accuracy and stability.

[0028] Working principle: When it is necessary to grind the inner wall of the valve body, the valve body is placed on the upper surface of the fixed plate 11, and the motor 13 is started to make the worm 14 mesh and rotate with the worm wheel 16, thereby driving the fixed shaft 15 and the clamping block 20 to clamp the valve body. The clamping block 20 and the stabilizing block 12 are connected by the connecting rod 19, so as to prevent the clamping block 20 from deflecting. The electric slide rail 9 is started to drive the electric slider 10, so as to drive the valve body to the bottom of the grinding roller 8. At this time, the hydraulic cylinder 3 and the motor 7 are started, and the fixed plate 4 is pushed down by the hydraulic cylinder 3, so as to drive the grinding roller 8 to grind the inner wall of the valve body. The protective cover 6 is covered on the top of the valve body to prevent debris from splashing, and the limit rod 501 and the return spring 502 cooperate to reduce the vibration generated during grinding.
