[0022] The implementation principle of a surface braiding device for metal hose processing in the embodiment of the present application is as follows:

[0023] When installing the hose, the worker rotates the three-jaw driven chuck 35 to the side in front of him through the turntable 34 to leave a working space for the upper tube. When installing the tube, the flange at one end of the hose can be quickly pushed to the side of the three-jaw driven chuck 35 by aligning the central axis 37, and the flange is fixed by the three-jaw driven chuck 35. After that, the three-jaw driven chuck 35 is manually pushed to reset, and the limit cylinder 36 extends to drive the push block 39 to abut against the turntable 34, and the turntable 34 can be limited by the limit block 38. After that, the linear guide slide 33 drives the hose to move to the side of the three-jaw active chuck 32, and the worker fixes the flange at one end of the hose on the three-jaw active chuck 32. Finally, the linear guide slide 33 drives the three-jaw driven chuck 35 to retreat a certain distance to properly tighten the hose.

[0024] After the hose is installed, the staff manually wraps one end of the braided wire around the hose and starts the rotating motor 31. Due to the presence of the central axis 37, when the rotating motor 31 drives the hose to rotate at high speed, the hose swings at a small amplitude. The servo motor 21 drives the reciprocating screw 22 to work, and the reciprocating screw 22 drives the moving seat 23 to move back and forth, so that the surface of the hose can be evenly wound.

[0025] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
