[0028] The cylinder processing support assembly provided by the utility model is explained and illustrated in detail below in conjunction with the drawings in the specification.

[0029] The cylinder processing support assembly provided by the utility model is arranged inside the cylinder to provide support for the cylinder when processing the cylinder, thereby preventing the cylinder from deforming during processing. In particular, when processing a cylinder structure with a relatively long axial length, by setting multiple support parts and adjusting the distance between two adjacent support parts through a connecting rod, a better support effect is achieved for the workpiece. The following is a detailed introduction of the present application in conjunction with specific embodiments:

[0030] In one embodiment, Figure 1 , Figure 2 As shown, the utility model provides a cylindrical processing support assembly, including: a support part 1 and a connecting rod 2, wherein two support parts 1 are provided, and the two support parts 1 are connected by at least two connecting rods 2, and the connecting rods 2 are threadedly connected to the support parts 1, and the two support parts 1 can be controlled to move closer to or farther from each other by rotating the connecting rods 2, so as to adjust the position of the support parts 1 and provide better support for the workpiece.

[0031] In one embodiment, Figure 2 As shown, the support portion 1 includes a fixing ring 11 and a supporting ring 12. The supporting ring 12 is sleeved on the outside of the fixing ring 11. An adjusting bolt 13 is provided on the fixing ring 11. The adjusting bolt 13 is used to provide support for the supporting ring 12, and the radial dimension of the supporting ring 12 is adjusted so that the supporting ring 12 can provide support for the inner wall of the cylinder.

[0032] The fixing ring 11 is a circular ring structure, and a plurality of adjustment holes are distributed along the circumference of the fixing ring 11. The adjustment holes extend along the radial direction of the fixing ring 11 and penetrate the side wall of the fixing ring 11, and the inner wall of the adjustment hole is provided with an internal thread. Optionally, the plurality of adjustment holes are evenly distributed along the circumference of the fixing ring 11. The first end of the adjusting bolt 13 passes through the adjustment hole from the inner side of the fixing ring 11, and the adjusting bolt 13 is threadedly connected to the adjustment hole. The length of the first end of the adjusting bolt 13 extending out can be changed by rotating the adjusting bolt 13. A connecting hole 111 is provided on the fixing ring 11, and the connecting hole 111 is parallel to the axis of the fixing ring 11. The inner wall of the connecting hole 111 forms an internal thread, and the outer peripheral wall of the connecting rod 2 is provided with an external thread, and two adjacent support parts 1 are away from or close to each other.

[0033] An adjustment notch 121 is formed on the support ring 12, and the size of the adjustment notch 121 is adjustable. A limiting cylinder 122 is arranged on the inner peripheral wall of the support ring 12, and the limiting cylinder 122 is arranged one-to-one with the adjustment hole. The first end of the adjustment bolt 13 extends into the limiting cylinder 122 and abuts against the bottom wall of the limiting cylinder 122. The first end of the adjustment bolt 13 provides thrust to the support ring 12 through the limiting cylinder 122. Optionally, the support ring 12 is made of an elastic metal material. In a natural state, the support ring 12 is located outside the fixing ring 11, and can ensure that the first end of the adjustment bolt 13 is located in the limiting cylinder 122. The support ring 12 enlarges the adjustment notch 121 under the thrust of the adjustment bolt 13, that is, the radial size of the support ring 12 increases. When the thrust of the adjustment bolt 13 is removed, the support ring 12 can be restored to a natural state under the action of the elastic force. When the adjusting bolt 13 extends toward the outside of the fixing ring 11, it can push the supporting ring 12 to move radially outward to enlarge the adjusting gap 121. When the adjusting bolt 13 shrinks toward the inside of the fixing ring 11, the supporting ring 12 can shrink under the action of elastic force to reduce the adjusting gap 121.

[0034] The inner cavity size of the limit cylinder 122 is larger than the outer diameter size of the adjusting bolt 13, so that the first end of the adjusting bolt 13 can undergo a certain amount of lateral displacement in the limit cylinder 122, thereby ensuring that when the support ring 12 is deformed by the thrust, the limit cylinder 122 can also undergo a certain amount of displacement, thereby avoiding affecting the deformation of the support ring 12.

[0035] Optionally, the inner cavity of the limiting cylinder 122 has a circular cross section, and the inner diameter of the limiting cylinder 122 is larger than the outer diameter of the adjusting bolt 13, and the first end of the adjusting bolt 13 can move laterally in the limiting cylinder 122, that is, a certain amount of movement occurs in the circumferential direction of the support ring 12. Alternatively, the inner cavity of the limiting cylinder 122 is in the shape of an elongated strip, and the inner cavity of the limiting cylinder 122 extends along the circumferential direction of the support ring 12, for example, it can be set to an elliptical, rectangular or similar hole of any shape, which can ensure that there is enough space between the limiting cylinder 122 and the adjusting bolt 13 for relative displacement when the support ring 12 is deformed.

[0036] In some embodiments, the end face of the first end of the adjusting bolt 13 is a convex hemispherical surface, which can reduce the contact area between the first end of the adjusting bolt 13 and the inner wall of the limiting cylinder 122, thereby reducing the friction force generated when the limiting cylinder 122 and the adjusting bolt 13 move relative to each other.

[0037] In some embodiments, a rib 123 is provided on the inner circumferential wall of the support ring 12, and each limiting cylinder 122 is connected to at least one rib 123. The rib 123 is provided perpendicular to the inner wall of the support ring 12, and is fixedly connected to the support ring 12 and the limiting cylinder 122. The provision of the rib 123 can improve the overall strength of the support ring 12 on the one hand, and can also improve the reliability of the connection between the limiting cylinder 122 and the support ring 12 on the other hand. Optionally, the rib 123 is provided along the circumference of the support ring 12, and a rib 123 is provided on both sides of each limiting cylinder 122. The multiple ribs 123 are independent of each other, and there is a gap between two adjacent ribs 123 to avoid interference between the ribs 123 when the support ring 12 is deformed.

[0038] In some embodiments, the connecting rod 2 is a double-headed screw rod, and two sections of external threads with opposite rotation directions are arranged on its outer wall. The two sections of external threads are respectively threadedly connected to a connecting hole 111 on a fixing ring 11. The internal thread of the connecting hole 111 matches the rotation direction of the external thread on the screw rod connected to it. When the connecting rod 2 rotates, the two supporting parts 1 approach or move away from each other, that is, they move in opposite directions.

[0039] In some embodiments, Figure 3 As shown, the cylinder processing support assembly also includes a bracket 3, two brackets 3 are provided, the support part 1 is located between the two brackets 3, and the two ends of the connecting rod 2 are rotatably connected to the two brackets 3. The support part 1 is supported by the bracket 3 to prevent the support part 1 from being deformed by ground compression due to gravity. Optionally, both ends of the connecting rod 2 extend to the other side of the bracket 3 to facilitate the rotation operation. Furthermore, a rotating handle is provided at at least one end of the connecting rod 2 to facilitate the rotation operation of the connecting rod 2.

[0040] In this embodiment, two connecting rods 2 are provided, and the axes of the two connecting rods 2 are located on the same diameter line of the fixing ring 11. The two connecting rods 2 rotate synchronously, which can ensure that the support part 1 can only move along the axial direction when moving, and will not rotate.

[0041] The use method of the cylinder processing support assembly of the present application includes:

[0042] like Figure 4As shown, the adjusting bolt 13 is adjusted according to the diameter of the cylinder 4 so that the diameter of the support ring 12 is smaller than the inner diameter of the cylinder 4. After the plate of the cylinder 4 is rolled and the positioning welding is completed in advance, the product is fine-tuned, the two support parts 1 are placed in the cylinder 4, and the connecting rod 2 is rotated to adjust the distance between the two support parts 1. Preferably, the distance between the two support parts 1 is 400mm-600mm, and then the adjusting bolt is rotated to increase the radial size of the support ring 12 and abut against the inner wall of the cylinder 4.

[0043] Optionally, it is necessary to ensure that the support ring 12 fits on the inner wall of the cylinder 4, that is, to ensure that the axis of the support ring 12 coincides with or is parallel to the axis of the cylinder 4. Whether the installation is in place can be determined by measuring the verticality of the support part 1 and the cylinder 4.

[0044] When adjusting the adjusting bolts 13 , they are adjusted in a cross-symmetrical order, that is, after adjusting the first adjusting bolt 13 , the bolt opposite to it is adjusted to ensure that the support ring 12 is evenly stressed.

[0045] After the installation of the cylinder processing support assembly is completed, the cylinder 4 is welded. Optionally, the welding is performed from the middle to both sides. After the welding is completed, the cylinder processing support assembly can be removed.

[0046] When the length of the cylinder 4 is small (smaller than the length of the connecting rod 2), the welding operation can be carried out on the support of the bracket 3. When the length of the cylinder 4 is large, the bracket 3 can be omitted. For example, when the length of the cylinder 4 is greater than the length of the two connecting rods 2, two cylinder processing support assemblies can be used simultaneously.
