[0020] Please refer to Figures 1-4 As shown, an embodiment of a precision casting part correction assembly of the present utility model includes a workbench 1 and a hydraulic cylinder 2. A plurality of sliding grooves 3 arranged in an array are opened at the top end of the workbench 1. A moving block 4 is slidably connected inside each of the plurality of sliding grooves 3. A correction ring 5 is fixedly connected to the top end of each of the plurality of moving blocks 4. The top end of the output end of the hydraulic cylinder 2 is fixedly connected with a lifting plate 6. A plurality of mounting grooves 7 arranged in an array are opened on the lifting plate 6. A first linkage rod 8 is fixedly connected inside each of the plurality of mounting grooves 7. A pressing rod 9 is rotatably connected to each of the plurality of first linkage rods 8. Mounting frames 10 are fixedly connected to the opposite walls of each of the plurality of correction rings 5. A second linkage rod 11 is fixedly connected to each of the plurality of mounting frames 10.

[0021] A guide rod 12 is fixedly connected inside each of the sliding grooves 3. The guide rod 12 is slidably connected with the moving block 4. The guide rod 12 is convenient for restricting the moving track of the moving block 4 inside the sliding groove 3.

[0022] A plurality of support columns 13 arranged in an array are fixedly connected to the bottom end of the workbench 1. The bottom ends of the support columns 13 are commonly fixedly connected with a base 14. The support columns 13 and the base 14 are convenient for providing stable support for the workbench 1.

[0023] The hydraulic cylinder 2 is fixedly installed at the central position on the base 14.

[0024] The output end of the hydraulic cylinder 2 passes through the workbench 1 and is fixedly connected with the lifting plate 6. The lifting plate 6 is located at the middle position of each correction ring 5. The oblique top ends of the pressing rods 9 are rotatably connected with the second linkage rods 11. The powerful power of the hydraulic cylinder 2 is convenient for driving the lifting plate 6 to rise or fall. The pressing rod 9 is convenient for driving the correction ring 5 to move through the second linkage rod 11.

[0025] When using the embodiment of the present utility model, first, the tubular casting to be corrected is sleeved and wrapped around each correction ring 5, so that the deformed part of the tubular casting corresponds to any one of the correction rings 5. Then, the hydraulic cylinder 2 is started. The output end of the hydraulic cylinder 2 extends upward, driving the lifting plate 6 to move upward. The upward movement of the lifting plate 6 drives a plurality of first linkage rods 8 to move upward together. The movement of each of the plurality of first linkage rods 8 drives the extrusion rod 9 to move together. At this time, the connection between the extrusion rod 9 and the first linkage rod 8 moves upward, and the connection between the extrusion rod 9 and the first linkage rod 8 rotates around the first linkage rod 8. At this time, the oblique top ends of the extrusion rods 9 drive the second linkage rods 11 to move outward, and the connection between the extrusion rod 9 and the second linkage rod 11 rotates around the second linkage rod 11. Each of the second linkage rods 11 drives the correction ring 5 to move through the mounting bracket 10. The movement of the correction ring 5 drives the moving block 4 to move inside the sliding groove 3. The movement of the moving block 4 is guided by the guide rod 12. The simultaneous outward movement of the plurality of correction rings 5 squeezes the inner wall of the tubular casting. At this time, the correction ring 5 corresponding to the deformed position of the tubular casting squeezes the deformed part of the casting back to its original shape. At this time, the hydraulic cylinder 2 can drive each component back to its original position.
