When utilizing the present invention to carry out robot binding operation, rolling process is performed rolling program by robot gribing knurling tool, moves along parts profile and is sequentially completed the rolling of whole car door, and above technology is all known for those of ordinary skills.In rolling process, along with robotic arm is along rolling contour motion, only roller rotates, and all the other rolling head assemblies do not move relatively, and this process is realized by bearing in rolling body, and namely bearing realizes the separation of motion.Rolling pressure is delivered on spring by guide rod, and when rolling pressure is less than or equal to spring force, spring does not compress and do not extend yet, spring and drum shaft geo-stationary, now rolling constant pressure, and roller-head works under rigid state.When rolling pressure is more than spring force, guide rod moves upward, and compresses spring; spring force increases, when rolling pressure and spring force balance, and the two geo-stationary; keeping constant pressure rolling, roller-head is in the resilient protection stage, can alleviate the impact of roller-head and workpiece.When rolling pressure reduces, at compression spring, rolling axle moves downward, when equilibrium is reached, and the two geo-stationary.Concrete motion is as follows, trundle in rolling body or big roller contact workpiece along profile roll time, be subject to rolling pressure and act on roller-head, pre-rolling power is less, spring in spring buffer is indeformable, and each hinge does not rotate, and whole roller-head is in the rigid system stage.When end pressure is bigger, when rolling pressure is more than the spring pressure set, guide rod moves upward the camber of spring caused in spring buffer, each hinge utilizes plane four rod principle to rotate, entering the another one rigid system stage, the flange that workpiece is reserved in punching press is turned down by frictional force between rolling body and workpiece to the inside, thus outside plate being treated, bound edge tightly compresses inner panel, outside plate and inner panel is made to be integrated into one, it is achieved rolling pressing edge covering.
The industrial applicibility of the present invention
1, by chain connection will be connected by between support, spring buffer, guide rod and rolling body, constitute four-bar linkage, simple in construction, be prone to use, solve vehicle body shutter member inner and outer plates robot edge-coating pressure control problems, improve control accuracy movement position and speed is accurate, good energy-conserving effect.
2, according to the pressure data that rolling effect and rolling pressure acquisition device obtain, track can be modified, read pressure in real time, it is ensured that the track of robot keeps consistent with the track of roller, strong adaptability.
3, by being diminished by the height of roller-head support, cylinder is directly connected through the hinge with rolling body, can ensure the rigidity that roller-head is overall after simplifying structure, and roller-head is more accurate to the power transmission of robot end, facilitates the replacing of roller-head.
Although embodiment of the present invention are disclosed as above, but it is not restricted in description and embodiment listed utilization.It can be applied to various applicable the field of the invention completely.For those skilled in the art, it is easily achieved other amendment.Therefore, under the general concept limited without departing substantially from claim and equivalency range, the present invention is not limited to specific details and shown here as the legend with description.
