Abstract
A visual on-line measuring device for inner pipe cross-section distortion during bending of metal pipe with variable diameter. The visual on-line measuring device includes: a visual inspection module, a hose, an in-pipe support device, and an axial feeding device. The hose is mounted in the axial feeding device, one end of the hose extends out of the axial feeding device and is mounted with the in-pipe support device, and the visual inspection module is mounted at one side of the in-pipe support device away from the axial feeding device.
Claims8
A visual on-line measuring device for inner pipe cross-section distortion during bending of metal pipe with variable diameter, comprising:
- a visual inspection module;
- a hose;
- an in-pipe support device;
- and
- an axial feeding device,
- wherein:
- the hose is mounted in the axial feeding device, one end of the hose extends out of the axial feeding device and is mounted with the in-pipe support device, and the visual inspection module is mounted at one side of the in-pipe support device away frohe axial feeding device;
- the in-pipe support device comprises a variable-diameter sliding bar mechanism and spring locking mechanisms, the variable-diameter sliding bar mechanism is fixedly connected to the one end of the hose extending out of the axial feeding device, the visual inspection module are fixedly mounted on an end face of the variable-diameter sliding bar mechanism away from the axial feeding device, and a plurality of locking sliding bars of the variable-diameter sliding bar mechanism are mounted with corresponding spring locking mechanisms;
- and
- the spring locking mechanisms comprise a buckle;
- a side face of each locking sliding bar is disposed with a locking sliding bar special-shaped sliding groove, one end of the buckle is rotatably mounted on an outer circumferential side face of a second sliding block disc in a clearance fit manner, the other end of the buckle is arranged with a boss that is inserted into the locking sliding bar special-shaped sliding groove, and realizes guiding sliding along the locking sliding bar special-shaped sliding groove;
- and in a case that the buckle is positioned at a bottom of the locking sliding bar special-shaped sliding groove, the locking sliding bar is in a maximum variable diameter position, and in a case that the buckle is positioned at a top of the locking sliding bar special-shaped sliding groove, each locking sliding bar is in a minimum variable diameter position.
