In figure: 1 component, 2 forks, 3 testing agencies, 4 connecting rods, 5 crossbeams, 6 guide waies, 7 returning springs, 8 rectilinear motion bodies.
Detailed description of the invention
As depicted in figs. 1 and 2, a kind of travelling table Anti-collision mechanism, comprise two groups of planar linkage mechanisms, often organize planar linkage mechanism comprise can relatively workbench swing fork 2, can relatively workbench rectilinear motion rectilinear motion body 8 and be the guide way 6 of linear movement guide of rectilinear motion body, the relative workbench of guide way is fixed.It is hinged that fork passes through the first pin joint and workbench or component 1, and the relative workbench of component is fixed.Connecting rod 4 by the second pin joint and rectilinear motion body hinged, connecting rod by the 3rd pin joint and fork hinged, the angle that the line of the line of the first pin joint and the 3rd pin joint and the second pin joint and the 3rd pin joint is formed is obtuse angle, and the opening at obtuse angle is towards workbench.First the crossbeam 5 contacted with object collision and two forks relatively fixing, plane orthogonal residing for crossbeam and planar linkage mechanism, two groups of planar linkage mechanisms are arranged along crossbeam length direction interval arranged side by side, and the first pin joint and crossbeam lay respectively at the both sides of the 3rd pin joint.A rectilinear motion body action at least detects in relatively-stationary testing agency 3 with workbench, and testing agency's detection of straight lines action of moving body is to control the reaction that anticollision made by workbench.
After collision is eliminated, rectilinear motion body resets under the restoring force of returning spring 7, realizes automatically reseting of Anti-collision mechanism.
Particularly, guide way is fairlead, and rectilinear motion body is the sliding bar be arranged in fairlead.
More specifically, sheathed returning spring on sliding bar, returning spring and the second pin joint lay respectively at the both sides of fairlead, and when the second pin joint is away from fairlead, the elastic force of returning spring increases.
Particularly, testing agency is travel switch, and the action of rectilinear motion body makes contact action.
In order to the anticollision distance of travelling table can be adjusted, 3rd pin joint is the tie point of the first articulated section and second articulated section of matching, first articulated section is arranged on fork, second articulated section is arranged on connecting rod, some first articulated sections along oscillating bar length direction in turn interval arrange, each first articulated section and the second articulated section hinged for the formation of one.Adjust the second articulated section to coordinate from the first different articulated sections, just can adjust the anticollision distance of travelling table
The both ends suspension of crossbeam, makes the protective range of Anti-collision mechanism wider like this.
The utility model proposes the low and travelling table Anti-collision mechanism that is safe and reliable and mechanical trigger-type that protective range is wider of a kind of cost, mostly part is section bar, and welding processing amount is few, and therefore cost is low, also reliable, be particularly useful for protection width 2 meters and above situation.
