[0021] In order to make the technical means, creative features, purposes and effects of the utility model easy to understand, the utility model is further described below in combination with specific embodiments.

[0022] Please refer to Figure 1 、 Figure 2 The utility model provides a novel automobile safety belt conduit pipe bending machine technical scheme:

[0023] Fixed piece 1 is clamped and fixed to the end of pipe;

[0024] Base 2 is used for placing pipe;

[0025] Pipe assembly, including first slide rail 31, first driving member 32, first push block 33, first driving member 32 pushes first push block 33 and displaces on first slide rail 31, first push block 33 is close to pipe, and pipe assembly is driven by a rotating platform 6, and makes pipe assembly rotate along base 2;

[0026] The sliding limiting assembly comprises a second sliding rail 43, a second driving member 42, and a second push block 41. The second driving member 42 pushes the second push block 41 to displace on the second sliding rail 43. The second push block 41 is attached to the side of the bent pipe. A third driving member 52 is installed on one side of the sliding limiting assembly, and the pushing direction of the third driving member 52 is parallel to the bent pipe. The first push block 33 and the second push block 41 are both provided with a groove A corresponding to the bent pipe. The fixing member 1 is a clamping air cylinder. The sliding limiting assembly is installed on a third sliding rail 51, so that the third driving member 52 pushes the sliding limiting assembly to slide along the third sliding rail 51. The third sliding rail 51 is parallel to the length direction of the bent pipe. The first driving member 32, the second driving member 42, and the third driving member 52 are all air cylinders.

[0027] Further, the base 2 is provided with a notch B corresponding to the bent pipe. The first push block 33 and the notch B clamp the bent pipe, so that the bent pipe is placed on the base 2.

[0028] In one embodiment, the bent pipe assembly is arranged on the front side of the sliding limiting assembly, so that the bent pipe assembly corresponds to the first end of the bent pipe, and the sliding limiting assembly corresponds to the side of the bent pipe.

[0029] In one embodiment, the rotating platform 6 is driven by a servo motor 77, so that the bent pipe assembly rotates around the base 2, thereby achieving the purpose of processing a straight pipe into a bent pipe.

[0030] Working principle: The existing manipulator places the unprocessed bent pipe on the base 2, and the fixing member 1 clamps and fixes the unprocessed bent pipe during the process. Then, the bent pipe assembly and the sliding limiting assembly are started, so that the first push block 33 and the second push block 41 contact the unprocessed bent pipe, and the unprocessed bent pipe is stabilized on the base 2. At this time, the fixing member 1 releases the fixation of the unprocessed bent pipe. The rotating platform 6 drives the bent pipe assembly to rotate and press the bent pipe. During this period, in order to avoid the breakage of the bent pipe, the third driving member 52 pushes the sliding limiting assembly to move, so that the bent pipe is displaced for a short distance, thereby avoiding the breakage of the bent pipe.
