The specific embodiment
Below in conjunction with accompanying drawing the utility model is further described, the utility model is not constituted any limitation.
When part is welded, require welding gun certain distance to be arranged apart from pad, hypertelorism or too closely all can not normally weld, and weld at the circular arc corner of part, it is constant to hold its constant distance, only need find out the central point of circular arc corner, rotate welding with welding gun centring point and around the center and can reach the constant purpose of constant distance.Based on above thinking; the utility model has used synchronous steering mechanism to reach its purpose; its principle is referring to Fig. 1; this synchronous steering mechanism comprises and being parallel to each other and the montant 1 of equal in length; 2; 3 and be parallel to each other and the cross bar 4 of equal in length; 5; wherein cross bar 4 respectively with montant 1; 2; 3 end is hinged; cross bar 5 respectively with montant 1; 2; 3 centre position is hinged; form parallelogram; wherein montant 1; 2 the other end are fixed on (support) on a certain plane; fixing point is respectively A and B; the other end C point and the A of montant 3; the B point is on same straight line; when this synchronous steering mechanism deforms; promptly around fixing point A; during the B swing, C point position is still protected constant.At this moment, can be with the central point of C point as part circular arc corner, and be fixed in welding gun on the montant 3 and adjust distance, at this moment only need the synchronous steering mechanism of swing can realize the operation of equidistant welding.
Embodiment one
As Fig. 2, shown in Figure 3, this circular arc corner welding mechanism, comprise welding gun 11 and synchronous steering mechanism, synchronously steering mechanism comprises and being parallel to each other and first support bar 6 of equal in length, second support bar 7 and being parallel to each other and the head rod 8 of equal in length, second connecting rod 9, and be provided with the dwang 10 parallel with first support bar 6, wherein head rod 8 respectively with first support bar 6, second support bar 7, the end of dwang 10 is hinged, second connect 9 respectively with first support bar 6, the centre position of second support bar 7 is hinged, simultaneously hinged with dwang 10, form parallelogram, first support bar 6, the end and the support of second support bar 7 are articulated in A, the B point, simultaneously, the extended line of AB and dwang elongation line crosspoint are the C point, when this synchronous steering mechanism deforms, promptly around fixing point A, during the B swing, C point invariant position, adjust the welding gun distance and be fixed on the dwang 10 according to part 12 circular arc knuckle radius, promptly can carry out the welding of circular arc corner the part 12 that fixes.Part circular arc shown in Figure 3 is an external corner, when needs weld the inner corner trim circular arc, only needs to adjust welding gun 11 length distance and gets final product, and principle is identical with operation.
