Detailed description of the invention
Below in conjunction with accompanying drawing, specific embodiments of the invention are elaborated.
Positioning and clamping mechanism for auto welding jig of the present invention, as shown in Figure 1,2,3, 4, comprises positioning unit and clamping unit;
Described positioning unit comprises some connecting plates 3, positioning cylinder 4, back-up block 5, guide rod 6 and alignment pin 8, described connecting plate 3 is encircled into a upper and lower end face opening, there is the box like structure of cavity, described box like structure at least comprises the relative connecting plate 3 in one group of position, wherein one group of connecting plate 3 has the through hole of axes coincide, be fixed with back-up block 5 outside a connecting plate 3 in this group connecting plate 3, and described back-up block 5 have the through hole coincided with connecting plate 3 through-bore axis;
Described positioning cylinder 4 piston rod end is fixedly connected with guide rod 6 one end, and described guide rod 6 the other end is fixedly connected with alignment pin 8;
Described alignment pin 8 stretches into from connecting plate 3 through hole having through hole, and under positioning cylinder 4 piston rod original state, alignment pin 8 is positioned at back-up block 5 through hole, and under positioning cylinder 4 piston rod stretches into state, alignment pin 8 can slide and give prominence to back-up block 5 through hole;
Described clamping unit comprises clamping cylinder 9 and clamp 10, and clamping cylinder 9 piston rod is fixedly connected with clamp 10, and clamp 10 and described back-up block 5 are oppositely arranged.
