Description
Technical field
The utility model relates to weld jig, especially relates to a kind of auto welding jig.
Background technology
In process of production, the stability to weld jig and the repetitive positioning accuracy of clamp mechanism require very high automobile industry.The impulsive force that hydraulic cylinder (cylinder) piston of clamp mechanism produces clamp mechanism is at present larger, piston action power causes additional stress large to mechanism and product impact, can cause the defects such as clamp arm distortion, make the repetitive positioning accuracy of weld jig poor, the maintenance cost of equipment is higher.
Summary of the invention
The utility model object is to provide one not yielding, the auto welding jig that repetitive positioning accuracy is high.
For achieving the above object, the utility model can be taked following technical proposals:
Auto welding jig described in the utility model, comprises fixed pedestal; Described fixed pedestal right side is hinged with hydraulic cylinder by the first bearing pin, is hinged by the middle part of the second bearing pin and spill leading arm at fixed pedestal middle part, is hinged by the middle part of the 3rd bearing pin and clamp arm at top, fixed pedestal right side; Be provided with gathering sill at described spill leading arm right side opening, in described gathering sill, be provided with first axis of guide; Be provided with return spring at spill leading arm right-hand member, the described return spring other end is connected with described clamp arm right-hand member; The hydraulic stem top of described hydraulic cylinder is connected with the middle part of V-shape piston stroke adjustment arm, offers adjustment tank in the upper end of described V-shape piston stroke adjustment arm, is provided with second axis of guide in described adjustment tank; The upper end of described V-shape piston stroke adjustment arm is hinged by described second axis of guide and the clamp arm that is positioned at described the 3rd bearing pin rear portion, and the other end of described V-shape piston stroke adjustment arm is hinged by described first axis of guide and spill leading arm right part; Be provided with limited block at the fixed pedestal top that is positioned at spill leading arm left end limes superiors position.
The utility model advantage has been to eliminate the impact of hydraulic cylinder (cylinder) piston rod movement to clamp arm, reduces the distortion of mechanism, has ensured to step up the accurate of position, guarantees the uniformity of product; The dimension precision requirement of piston rod movement is reduced, thereby reduced the required precision to clamp mechanism, reduced processing cost; The additional forces simultaneously applying by eliminating the suffered piston of clamp mechanism, reduces greatly to the rigidity requirement of clamp mechanism, has realized the lightweight of clamp mechanism, effectively reduces the processing and manufacturing cost of fixture.

Detailed description of the invention
As shown in 1,2 figure, auto welding jig described in the utility model, comprises fixed pedestal 1; Described fixed pedestal 1 right side is hinged with hydraulic cylinder 3 by the first bearing pin 2, is hinged by the second bearing pin 4 and the middle part of spill leading arm 5 at fixed pedestal 1 middle part, is hinged by the 3rd bearing pin 6 and the middle part of clamp arm 7 at fixed pedestal 1 top, right side; Be provided with gathering sill at described spill leading arm 5 right side openings, in described gathering sill, be provided with first axis of guide 8; Be provided with return spring 9 at spill leading arm 5 right-hand members, described return spring 9 other ends are connected with described clamp arm 7 right-hand members; Piston rod 10 tops of described hydraulic cylinder 3 are connected with the middle part of V-shape piston stroke adjustment arm 11, offer adjustment tank in the upper end of described V-shape piston stroke adjustment arm 11, are provided with second axis of guide 12 in described adjustment tank; The upper end of described V-shape piston stroke adjustment arm 11 is hinged with the clamp arm 7 that is positioned at described the 3rd bearing pin 6 rear portions by described second axis of guide 12, and the other end of described V-shape piston stroke adjustment arm 11 is hinged with spill leading arm 5 right parts by described first axis of guide 8; Be provided with limited block 13 at fixed pedestal 1 top that is positioned at spill leading arm 5 left end limes superiors positions.
When operation, the piston rod 10 of hydraulic cylinder 3 moves upward, and first promotes V-shape piston stroke adjustment arm 11 upwards, and it is vertical that spill leading arm 5 keeps under the effect of limited block 13, limit first axis of guide 8 and make piston rod 10 along straight line upwards, clamp arm 7 is restricted to rotation clamping; When clamp arm 7 contacts with limited block 13 and the piston rod 10 of hydraulic cylinder 3 while continuing to move upward, now second axis of guide 12 continues to slide backward in the adjustment tank of V-shape piston stroke adjustment arm 11, the motion of piston rod 10 does not produce additional stress, ensures that clamp arm 7 reaches the state of accurate location; In the time that piston rod 10 moves downward, second axis of guide 12 in the adjustment tank of V-shape piston stroke adjustment arm 11 to front slide, drive clamp arm 7 rotating opening, first axis of guide 8 drives V-shape piston stroke adjustment arm 11 to rotate, and under return spring 9 effects, spill leading arm 5 homings and limited block 13 are fitted, can eliminate like this clamping movement steps up mechanism impact to fixture, the rigidity requirement that reduces clamp mechanism, has reduced the required precision to clamp mechanism, has reduced processing cost.
