Description

Technical Field

[0001] The utility model relates to a correction tool for an arc-shaped thin-walled cylinder, and relates to the technical field of tooling for casting production. Background Art

[0002] For casting processing, especially for arc-shaped thin-walled cylinder casting processing, after all the processing of the casting is completed, the casting needs to be annealed and corrected.

[0003] In order to prevent the arc-shaped thin-walled cylinder casting from deforming inward during the annealing correction process, a correction tool is required to support and correct the arc-shaped thin-walled cylinder. The existing correction tool is shown in Chinese patent publication number CN115464008A. Although a plurality of circular array correction bolts are installed on the outer circumference of the annular correction block to achieve multi-point inner surface support, it is impossible to achieve the problem of contact between the fitting surfaces to support the inner surface of the arc-shaped thin-walled cylinder to prevent the inner surface deformation. Utility Model Content

[0004] In order to solve the above technical problems, the utility model provides a correction tool for an arc-shaped thin-walled cylinder.

[0005] The utility model is realized through the following technical solutions.

[0006] The utility model provides a correction tool for an arc-shaped thin-walled cylinder, comprising:

[0007] The central movable block is arc-shaped and used to match the arc-shaped through hole inside the arc-shaped thin-wall cylinder;

[0008] All of them are arc-shaped and are used to match the inner surface of the arc-shaped through hole of the arc-shaped thin-walled cylinder and the arc-shaped outer surface of the center movable block, namely the lower right movable block, the upper right movable block, the upper left movable block and the lower left movable block.

[0009] It also includes an arc-shaped thin-walled cylinder with an arc-shaped through hole inside. The arc-shaped thin-walled cylinder is in an arc-shaped thin-walled shape; the central movable block is located at the center of the through hole inside the arc-shaped thin-walled cylinder.

[0010] It also includes a lower bottom plate that serves as a support and bears force to closely contact the outside of the arc-shaped thin-walled cylinder, and fixed plates are fixed at both ends of the lower bottom plate for relying on contacting the side edges of the outside of the arc-shaped thin-walled cylinder; movable baffles that can be movably adjusted are placed on the lower bottom plate between the fixed plates, and the movable baffles are multiple and are placed in the gaps between the outsides of the arc-shaped thin-walled cylinder.

[0011] The fixed plate has an arcuate surface for tightly contacting the side surface of the arcuate thin-walled cylinder; the movable baffle has an arcuate surface for tightly contacting the side surface of the arcuate thin-walled cylinder.

[0012] The lower base plate is detachably fixedly connected with an upper cover plate which is in close contact with the outer surface of the arc-shaped thin-walled cylinder.

[0013] The lower base plate is detachably fixedly connected to the upper cover plate by bolts and nuts.

[0014] The ends of the lower base plate and the upper cover plate are both detachably fixedly connected with lifting pins.

[0015] The beneficial effect of the utility model is that when the arc-shaped thin-walled cylinder is heated and annealed in the annealing equipment, the inside of the arc-shaped thin-walled cylinder is in close contact with the lower right movable block, the upper right movable block, the upper left movable block and the lower left movable block to support and limit the position, thereby solving the problem that the arc-shaped thin-walled cylinder cannot achieve close contact with the surface to support the inner surface and prevent deformation of the inner surface.

DETAILED DESCRIPTION

[0025] The technical solution of the utility model is further described below, but the scope of protection required is not limited to the description.

[0026] like Figures 1 to 8 shown.

[0027] A correction tool for an arc-shaped thin-walled cylinder of the present application comprises:

[0028] When in use, the central movable block 1 is installed at the center of the through hole inside the arc-shaped thin-walled cylinder 6, and the central movable block 1 is arc-shaped to match the arc-shaped through hole inside the arc-shaped thin-walled cylinder 6;

[0029] When in use, the lower right movable block 2, the upper right movable block 3, the upper left movable block 4 and the lower left movable block 5 are located between the central movable block 1 and the internal through hole of the arc-shaped thin-walled cylinder 6. The lower right movable block 2, the upper right movable block 3, the upper left movable block 4 and the lower left movable block 5 are all arc-shaped to match the inner surface of the arc-shaped through hole of the arc-shaped thin-walled cylinder 6 and the arc-shaped outer surface of the central movable block 1.

[0030] It also includes a lower bottom plate 7 as a support and force bearing, and fixing plates 8 are fixed at both ends of the lower bottom plate 7 for contacting the outer side of the arc-shaped thin-walled cylinder 6, and the fixing plates 8 have an arc-shaped surface for tightly contacting the side of the arc-shaped thin-walled cylinder 6.

[0031] A movable baffle 9 that can be movably adjusted is placed on the lower bottom plate 7 between the fixed plates 8. The movable baffle 9 has an arc-shaped surface for tightly contacting the side of the arc-shaped thin-walled cylinder 6. The movable baffle 9 is placed in the gap between the outside of the arc-shaped thin-walled cylinder 6 so that the arc-shaped surface of the movable baffle 9 tightly contacts the outside of the arc-shaped thin-walled cylinder 6.

[0032] The lower base plate 7 is detachably fixedly connected to the upper cover plate 10 by bolts 12 and nuts 13. The upper cover plate 10 is in close contact with the outer upper surface of the arc-shaped thin-walled cylinder 6, and the lower base plate 7 is in close contact with the outer lower surface of the arc-shaped thin-walled cylinder 6. The arc surface of the fixed plate 8 and the arc surface of the movable baffle plate 9 are in close contact with the outer left and right sides of the arc-shaped thin-walled cylinder 6, so that the outer arc surface of the arc-shaped thin-walled cylinder 6 is closely contacted and limited by the lower base plate 7, the fixed plate 8, the movable baffle plate 9, and the upper cover plate 10.

[0033] The ends of the lower base plate 7 and the upper cover plate 10 are detachably fixedly connected with lifting pins 14 through pin holes or threaded holes.

[0034] A central movable block 1 is installed inside the arc-shaped thin-walled cylinder 6, and the lower right movable block 2, the upper right movable block 3, the upper left movable block 4 and the lower left movable block 5 are supported to form a whole. Multiple arc-shaped thin-walled cylinders 6 are placed on the lower base plate 7 as a whole and are separated by movable baffles 9. The outer arc surfaces of multiple arc-shaped thin-walled cylinders 6 are tightly contacted and limited by the lower base plate 7, the fixed plate 8, the movable baffle 9, and the upper cover plate 10. After the inside and outside of the arc-shaped thin-walled cylinder 6 are limited, it is connected to the lifting pin 14 through the lifting equipment and hoisted into the annealing equipment for heating and annealing.

[0035] When the curved thin-walled cylinder 6 is heated and annealed in the annealing equipment, the problem that the curved thin-walled cylinder 6 cannot achieve surface contact to support the inner surface and prevent deformation of the inner surface is solved because the interior of the curved thin-walled cylinder 6 is in close contact with the lower right movable block 2, the upper right movable block 3, the upper left movable block 4 and the lower left movable block 5.
