For ring-shape accessory, part is supported on the bracer supporting seat, and the piston rod of cylinder is retracted, part is pressed on support seat by pressure arm, and the piston rod of such cylinder, in the intermediate active of part, saves the space around part, the weld pass making welding gun is broader, and dress pickup is easy.
In such scheme, the stem of described pressure arm arranges regulation briquetting, and described regulation briquetting is in " recessed " shape, in the groove of the centre that the stem of described pressure arm is stuck in regulation briquetting, and, between pressure arm and regulation briquetting, pad is set.Regulation briquetting is set, when the thickness difference of part, suitable adjustment can be done, as changed regulation briquetting so that the scope of application of this fixture is wider.
In such scheme: the upper surface of described support seat arranges two pieces bracer limiting plates away from one end of through hole, and described bracer is arranged between two pieces bracer limiting plates.So easily changing different bracers, the scope of application is wider.
In such scheme, described support seat is three, and corresponding described pressure arm is also three.So form three-jaw clamping device, clamp more firm.
In such scheme: the upper surface of positioning seat is additionally provided with key seat on described, described key seat being provided with alignment pin, described key seat supports between seat at two.Alignment pin coordinates with the pin-and-hole on part, plays the effect of auxiliary positioning, it is ensured that the precision of the location of part.
As preferably: described key seat is two, two key seats lay respectively at different two and support between seat.
Beneficial effect: this utility model controls three pressure arms by a cylinder operation, reduces the loaded down with trivial details mechanism of weld jig body, simple in construction, low cost of manufacture, makes weld pass more unobstructed simultaneously, operation smoothness, improves work efficiency.
