[0030] Example

[0031] like Figures 1 to 3 As shown,

[0032] A compressor pipe straightening mechanism includes a translational motion plate 5, on which two opposing clamping cylinders 8 are mounted in the fore-aft direction. The driving ends of the clamping cylinders 8 drive the inner clamping fixture 9 to move in the fore-aft direction. A roller 14 is mounted on the rearward correction end of the clamping fixture 9. Two clamping mounting frames 16 are arranged sequentially from top to bottom at the rearward correction end of the clamping fixture 9. A shaft 18 is mounted between the two clamping mounting frames 16 via a bearing 20, and the roller 14 is mounted in the middle of the shaft 18.

[0033] 1. The translational motion plate 5 moves left and right on the bottom plate 1 below:

[0034] A translation cylinder 4 is installed on one side of the base plate 1 through a translation cylinder mounting seat 3. The bottom of the translation motion plate 5 is connected to the base plate guide rail 2 installed on the base plate 1 along the left and right directions through a translation slider 6. The driving end of the translation cylinder 4 drives the translation motion plate 5 to move in the left and right directions through the translation cylinder connecting plate.

[0035] 2. The clamping cylinder 8 is mounted on the translational motion plate 5 via the clamping cylinder mounting base 7. The left bottom of the clamping fixture 9 is connected to a clamping guide rail 11 mounted on the translational motion plate 5 along the front-back direction via a clamping slider 10.

[0036] 3. A limit block 13 is installed on the translational motion plate 5 between the two clamping fixtures 9. Guide posts 12 are mounted on the limit block 13 along the front-to-back direction. The guide posts 12 are connected to the front and rear clamping fixtures 9, respectively. The limit block 13 limits the left-right movement of the compressor pipe 15, and the guide posts 12 guide the front-to-back movement of the two clamping fixtures 9.

[0037] 4. The top of shaft 18 passes through mounting hole 17 of the upper clamping frame 16 and is then secured with nut 19. The bottom of shaft 18 is threadedly connected to mounting threaded hole 21 of the lower clamping frame 16. This allows for easy installation and removal of the roller, facilitating replacement and enhancing its applicability.

[0038] The roller 14 comprises two outer roller bodies 22, from top to bottom, with an inner roller support block 23 disposed between the two outer roller bodies 22. The outer roller bodies 22 have a smooth V-shaped surface on the outside, and the inner roller support block 23 has a smooth curved surface on the outside. The smooth V-shaped surface is convex outward, and the smooth curved surface can be slightly convex outward or slightly concave inward. The interaction between the outer smooth V-shaped surface and the inner smooth curved surface achieves clamping of the compressor pipe 15.

[0039] During straightening, the compressor pipe 15 is located on the roller inner support block 23 between the two roller outer shells 22 , and the smooth contact surface can reduce damage to the surface of the compressor pipe 15 .

[0040] Brief description of the working process of this utility model:

[0041] 1. Install this mechanism on the side of the line body and match the blocking mechanism, lifting mechanism and pressing mechanism on the existing line body.

[0042] 2. When the product on the line stops at the above position, the blocking mechanism on the line will not release it, and at the same time the lifting mechanism and the pressing mechanism will be installed with the compressor to press it.

[0043] 3. The clamping cylinder 8 opens.

[0044] 4. Move cylinder 4 back to the retracted position so that the mechanism is close to the root of the compressor housing.

[0045] 5. The clamping cylinder 8 is closed. The diameter of the roller 14 in the straightening end tooling on the rear side of the clamping cylinder 8 is consistent with the diameter of the compressor tube 15. After clamping the compressor tube 15, the translation cylinder 4 extends out in parallel to straighten the compressor tube 15. A bearing is installed in the roller to enable it to rotate.

[0046] 6. The translation cylinder 4 drives its clamping mechanism to perform linear motion on two guide rails parallel to it.

[0047] 7. After the translation cylinder 4 is in place, the clamping cylinder 8 opens to complete the straightening action.

[0048] In the description of the present invention, it should be understood that the terms "center", "longitudinal", "lateral", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside" and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as limiting the present invention.
