The assembly requirements of the welding tooling fixture.
(1), the retaining pin assembly to the clamping body, you need to ensure that the base surface and the clamping body transverse center straight
(2), positioning and clamping brace of the stopper, spiral clamping device assembly to the clamping specific, to ensure that the base surface and clamping specific transverse center line parallel; positioning and clamping engine liner two pieces of pin mechanism, fast withdrawal spiral clamping device assembly to the clamping specific, the need to ensure that its center line and clamping specific transverse center line straight.
(3), positioning and clamping sequence 4 engine liner two-piece pin mechanism, fast withdrawal type spiral clamping device assembly, installed screws, with pin holes and pins to ensure that the pin mechanism and fast withdrawal type spiral clamping device right centerline and the distance and tolerance of the base surface of the retaining pin
(4), positioning and clamping sequence 3 nut M6 and horn support of the assembly of the spiral clamping mechanism assembly, mounted stud base screws, with pin holes and pins to ensure that the spiral clamping mechanism positioning tapered pin centerline and j blocking pin base surface distance and tolerance.
(5), positioning and clamping sequence 1 brace of the baffle plate, spiral clamping device assembly, mounted screws, with pin holes and pins to ensure that the baffle plate and spiral clamping device right end face and the distance between the base surface of the retaining pin
(6), installed on the spring, pressure plate and other parts to complete the entire assembly.
