Description
[technical field]
The present invention relates to transmission principle, referring in particular to be applied on the assembly fitting line provides the relaying of propulsive effort driving device for planker detours along arc track.
[background technology]
The fitting line that existing workpiece assemble flow is adopted generally is to adopt four sections straight line fitting lines to enclose rectangle; Or adopt the circular arc fitting line to connect relative two straight line fitting lines; The workpiece that need assemble gets into recirculation on the fitting line that surrounds, every station all can be implemented an operation or assemble some parts, thereby realizes pipelining; Increase work efficiency, make the assembling normalisation.In the fitting line equipment that surrounds like this, the change of the sense of motion of planker on the position of plugging between two straight fitting lines of needs solution workpiece and carrying workpiece and the sustainable supply problem of power are for adopting four sections straight line fitting lines to enclose the fitting line of rectangle; Realize that at present its sense of motion changes and the device of continuation operation is all very complicated; Adopt rectangular rail to realize total 180 ° when oppositely plugging into, respectively establish 90 ° of rotating tablees in place, two right angles, planker of every completion passes on; Need 4 90 ° of turns of completion, 4 time-delay pauses, 4 guide rails to align altogether; Manufacturing cost is obviously higher, and owing to repeatedly pause, operating efficiency is obviously lower.
Adopt arc orbit to connect the fitting line system of two straight line fitting lines, can make and continue more smooth and easyly between each straight line fitting line, continue supplementary question but still need to solve the propulsive effort of rectangle planker under sense of motion time changing condition on the arc orbit with transition.In the prior art, the parallel connection of the employing that has series roll shaft, when each roll shaft when all the transmission at gear is down by the band commentaries on classics, casing of placing on the roll axis or shaped steel can be by driven advancing; As shown in Figure 1, driven the motion of object (plane body) 101, and had the characteristic of " inseparable " between the driven roller 102, in case promptly the object below does not have roller; Forward movement just can stop, thereby roller must be omnidistance densely covered, and each driven roller all needs power; It is many to feed intake, and structure is very complicated, and cost is high; And the advance resistance that need overcome when adopting this structure does not have and reduces: F
Resistance=P
QualityK
RollScrupulously abide by " driving direction of driven roller and the conformability that is driven movement direction of object "; The key problem is, the planker that it can't the load-transfer device running roller under situation about existing between propulsive effort and the planker mass center working direction than wide-angle, can not effectively drive.
Therefore, a kind of drive relay simple in structure is provided, and real this drive relay driving device effectively reduces the driving resistance on the fitting line, can effectively continue to provide the propulsive effort that moves ahead for necessary, and is simple in structure, cost is low, and production efficiency is high.
