Abstract
Claims
1. A portable swage eccentricity correction apparatus, characterised in that: It includes a fixed main beam (1) with a hydraulic cylinder (2) at one end and a telescopic main beam (3) passing through the other end. The telescopic main beam (3) has a first correction part (4) at its extended end. The fixed main beam (1) has a main beam extension support beam (5) above the hydraulic cylinder (2) and a second correction part (6) at its end away from the fixed main beam (1).
2. The portable ring piece off-center correction apparatus of claim 1, wherein: The fixed main beam (1) includes a square steel main beam (11) made of square steel. One end of the square steel main beam (11) is provided with a hydraulic cylinder (2) through a main beam top plate (12) fixedly connected to it, and an annular reinforcing plate (13) is fixedly connected to the outer side of the other end. A first lifting ring (15) is fixedly connected to the center of the top surface of the annular reinforcing plate (13). A telescopic main beam (3) connected to the hydraulic cylinder (2) is passed through the inside of the square steel main beam (11). Multiple bolt through holes (16) are evenly provided on the side of the square steel main beam (11) along its axial direction and bolts are provided. An extension beam base (17) is provided on the top surface of the square steel main beam (11) near the main beam top plate (12) and a main beam extension support beam (5) is bolted to it.
3. The portable ring piece off-center correction apparatus of claim 2, wherein: The hydraulic cylinder (2) has a cylinder port (21) connected to the hydraulic oil pipe on its cylinder body.
4. The portable ring piece off-center correction apparatus of claim 3, wherein: The telescopic main beam (3) includes a square steel telescopic beam (31) made of square steel. One end of the square steel telescopic beam (31) is inserted into the square steel main beam (11) and connected to the hydraulic cylinder (2). The top surface of the other end is provided with a correction part mounting seat (32) and a first correction part (4) is provided by bolts.
5. The portable ring piece off-center correction apparatus of claim 4, wherein: The first correction part (4) includes a first correction fixing support beam (41) that is bolted to the correction part mounting base (32) and is perpendicular to the axial direction of the square steel telescopic beam (31). The two ends of the first correction fixing support beam (41) are respectively fixed with first correction support beams (42) that extend obliquely in the same horizontal plane. The two first correction support beams (42) are arranged in a mirror symmetrical manner with respect to the vertical plane where the axis of the square steel telescopic beam (31) is located. A rotating ring support bolt (43) is provided at one end of the outer side of each of the first correction support beams (42).
6. The portable ring piece off-center correction apparatus of claim 5, wherein: The main beam extension support beam (5) includes an extension beam mounting plate (51) bolted to the extension beam base (17). An extension beam rod (52) is provided on the top surface of the extension beam mounting plate (51). A second lifting ring (53) is provided at one end of the extension beam rod (52) near the square steel main beam (11). The second lifting ring (53) and the first lifting ring (15) are used together for hoisting the overall correction equipment. A second correction part (6) is provided at one end of the extension beam rod (52) away from the square steel main beam (11).
7. The portable ring piece off-center correction apparatus of claim 6, wherein: A dial indicator (54) is installed on the extension beam (52).
8. The portable ring piece off-center correction apparatus of claim 7, wherein: The second correction part (6) includes a second correction mounting seat (61) sleeved on the extension beam (52). The second correction mounting seat (61) has a second correction auxiliary mounting plate (62) extending horizontally outward on the side of the extension beam (52), and a rotating annular support bolt (43) is provided on the second correction auxiliary mounting plate (62). In addition, a threaded through hole is provided on the top surface of the second correction mounting seat (61), and bolts are used to lock and fix the second correction mounting seat (61) and the extension beam (52) together, thereby preventing displacement between the second correction mounting seat (61) and the extension beam (52).
9. The portable ring piece eccentricity correction apparatus according to any one of claims 2 to 8, characterized by: A fixing bolt (14) is provided at each of the four corners of the annular reinforcing plate (13).
10. The portable ring forging eccentricity correction device according to claim 9, characterized in that: The telescopic main beam (3) is provided with multiple beams of different lengths.
