Specific embodiment
For technical solution of the present invention is more clearly understood, specific embodiment makees into one the present invention with reference to the accompanying drawing
Walk explanation.
As shown in Figure 1-3, a kind of pressing roller round tube gauge length dotting machine of the present invention；It is ontology with vehicle frame 3, institute
It states vehicle frame 3 bottom four angle and is provided with the bearing block 2 of inner ring fitted bearing 21, and be provided with bottom in bearing 21 as starting arrow
First 11 idler wheel 1 and 21 inner ring of bearing be interference fitted, and is provided with internal hollow out on the vehicle frame 3 and conveniently dismantles from vehicle frame
The cover 8；The 8 front end two sides of the cover are equipped with backplate 82, and centre is equipped with the pressing groove 81 fallen in, and finger is facilitated to place pressing；
