[0002] Aluminum cylinder tubes are mainly used to manufacture pneumatic or hydraulic components, such as cylinders or oil cylinders. During the production of aluminum cylinder tubes, to ensure smooth sliding between the piston and the inner wall of the tube, the inner wall needs to be rolled to make it smooth. Traditional aluminum cylinder tube rolling equipment, because the aluminum cylinder tube is clamped on the worktable, cannot allow the rolling head to penetrate the entire inner hole of the tube; otherwise, the rolling head would collide with the fixture. Therefore, it is necessary to roll the inner hole of the aluminum cylinder tube from both ends, resulting in low processing efficiency.

[0003] In the prior art, an inner hole rolling device for aluminum cylinder tubes is disclosed with publication number CN220407757U. This device has a through hole on the fixture that matches the inner hole of the aluminum cylinder tube, so that the rolling head can penetrate the entire inner hole of the aluminum cylinder tube and perform inner hole rolling processing. There is no need to roll at both ends separately, and the processing efficiency is high.

[0004] However, the connection method, shape and size of the fixed clamp, moving clamp and rolling head in this rolling device are all fixed, and it is only suitable for processing aluminum cylinder tubes of the same specification and model. The range of application is small and it is difficult to meet the needs of use.

[0005] Therefore, those skilled in the art have provided a cylinder tube bore rolling device to solve the problems mentioned in the background art. Utility Model Content

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0030] Example 1

[0031] Please see the appendix Figure 1-5 A cylinder tube inner hole rolling device according to an embodiment of the present utility model includes a base 1, a top plate 6 is provided on the base 1, a plurality of guide rods 5 are fixedly connected between the base 1 and the top plate 6, a support plate 8 is slidably connected between the plurality of guide rods 5, and a rolling head 4 is rotatably connected to one side of the support plate 8.

[0032] A drive motor 10 is fixed on the support plate 8. A support frame 11 is fixed on the outside of the drive motor 10 on the support plate 8. An electric cylinder 7 is fixed on the top plate 6. The output end of the electric cylinder 7 is fixedly connected to the support frame 11. The output end of the drive motor 10 extends out of the support plate 8 and is connected to the rolling head 4. A disassembly assembly 9 is detachably connected between the support plate 8 and the rolling head 4. The rolling head 4 can be disassembled and replaced with rolling heads of different specifications through the disassembly assembly 9, which is suitable for rolling the inner hole of cylinder tubes of different specifications.

[0033] An opening 2 is provided in the middle of the base 1, and a clamping mechanism 3 is connected inside the opening 2. The clamping mechanism 3 is used to position and clamp cylinder tubes of different specifications and models.

[0034] The clamping mechanism 3 includes two fixed frames 31, each with an opening at both ends to prevent dust accumulation inside. The two fixed frames 31 are fixed on both sides of the opening 2. A bidirectional lead screw 34 is rotatably connected inside the fixed frame 31. Two fixed blocks 37 are slidably connected between the two bidirectional lead screws 34. The fixed blocks 37 are detachably connected to clamps 35. Different specifications and models of clamps 35 can be selected according to the specifications and models of the cylinder tube to be rolled, ensuring that the clamps 35 match the specifications and models of the cylinder tube to be rolled during operation. A semi-circular through hole 351 is provided below the clamps 35. The size of the two semi-circular through holes 351 combined matches the inner hole of the cylinder tube to be rolled. The clamps 35 can position and clamp the cylinder tube to be rolled. When the rolling head 4 is inserted into the inner hole of the cylinder tube for rolling, it can penetrate the entire inner hole of the cylinder tube, and the rolling head 4 will not collide with the clamps 35 or other components.

[0035] Each of the two fixed brackets 31 has a small motor fixed inside one end. The output ends of the two small motors are fixedly connected to two bidirectional lead screws 34 respectively. Both ends of the two bidirectional lead screws 34 are slidably connected to sliders 32. A connecting plate 33 is fixedly connected between two adjacent sliders 32. A fixing block 37 is fixedly connected to one side of the connecting plate 33.

[0036] When clamping and fixing the cylinder tube to be rolled, two small motors drive two double-acting lead screws 34 to rotate, and then the sliders 32 at both ends of the two double-acting lead screws 34 drive the two connecting plates 33 to move relative to each other, so that the two fixing blocks 37 can drive the two clamps 35 to move relative to each other to clamp the cylinder tube to be rolled.

[0037] Example 2

[0038] Based on Example 1, please refer to the appendix. Figure 1-5 Both ends of the fixing block 37 are slidably connected to spring clips 38. One side of the spring clips 38 is inclined. A U-shaped plate 36 is fixedly connected to the rear side of the clamp 35. Both ends of the U-shaped plate 36 are provided with connection ports 16. The connection ports 16 are connected to the spring clips 38. When changing the clamp 35, the U-shaped plate 36 and the clamp 35 connected to it can be slidably removed by pressing the spring clips 38 and retracting them into the fixing block 37. When assembling, the replaced clamp 35 is slidably inserted into the outside of the fixing block 37 through the U-shaped plate 36. When inserted, the U-shaped plate 36 presses the inclined surface of the spring clips 38 and automatically retracts into the fixing block 37. Then, when the connection port 16 of the U-shaped plate 36 is parallel to the spring clips 38, the spring clips 38 automatically pop out and lock the clamp 35. The installation and disassembly are convenient and the clamp 35 can be quickly replaced.

[0039] The disassembly assembly 9 includes a fixed sleeve 91, which is fixedly connected to the output end of the drive motor 10. A connecting seat 93 is fixedly connected to the rolling head 4. The connecting seat 93 is slidably connected inside the fixed sleeve 91. A bolt 92 connects the fixed sleeve 91 and the connecting seat 93. By removing the bolt 92, the fixed sleeve 91 and the connecting seat 93 can be separated, thereby enabling the replacement of rolling heads 4 of different specifications.

[0040] A limiting groove 14 is provided on one side of the fixing block 37, and a limiting block 15 is fixedly connected to one side of the U-shaped plate 36. The limiting block 15 and the limiting groove 14 cooperate with each other to improve the stability of the connection between the U-shaped plate 36 and the fixing block 37.

[0041] The opening 2 penetrates the base 1. A controller 12 is fixed on one side of the base 1, and a drawer 13 is slidably connected to one side of the controller 12. Due to the possibility of impurities, porosity, or slag inclusions in the raw materials of the cylinder tube, the material bonding force at these internal defects is weak during the rolling process. When subjected to the pressure of the rolling head 4, the material at the defective area is easily peeled off and forms debris. Moreover, after the rolling head 4 is worn, debris is also easily generated during rolling. Therefore, it is necessary to clean the operating table during rolling. However, in this device, the opening 2 penetrates the base 1, so even if debris is generated during rolling, it can fall directly into the drawer 13 below through the opening 2 for collection and treatment. It is not necessary to clean the operating table frequently, making the operation convenient and easy to keep the rolling operating table clean.

[0042] The above description provides a detailed account of one embodiment of the present invention. However, this description is merely a preferred embodiment and should not be construed as limiting the scope of the present invention. All equivalent variations and improvements made within the scope of the claims of the present invention should still fall within the patent coverage of the present invention.
