Vibration friction welding jig of sliced plastic air intake manifold

Abstract

The invention relates to a piece-type plastic intake manifold vibration friction welding jig, which includes an upper jig and a lower jig. The upper jig includes an upper mounting plate and an upper profile that matches the profile of the upper half of the intake manifold. The support positioning assembly, the upper contour support positioning assembly is composed of a plurality of small support positioning blocks Ⅰ; the lower fixture includes the lower mounting plate, the bottom plate, the base and the lower contour support positioning assembly that matches the contour of the lower half of the intake manifold , the lower contour support and positioning component is composed of a plurality of small support positioning blocks II assembled; the bottom plate is also provided with a hole positioning device, the hole positioning device includes a position mounting seat, a displacement cylinder, a positioning cylinder, a slideway, a slider and a positioning device. Semi-circular support block for fixing intake manifold holes. The contour support and positioning components on the upper and lower fixtures of the present invention are composed of a plurality of small support positioning blocks, which can be fine-tuned according to the product contour, so that the welding strength and reliability of the intake manifold are higher, and the Welding pass rate.

Description

technical field [0001] The invention relates to a welding jig, in particular to a vibrating friction welding jig for a sliced ​​plastic intake manifold. Background technique [0002] With the development of the automobile industry, energy saving and environmental protection have become two major issues of the automobile industry. Functional plastics are constantly replacing metal materials due to their light weight, low manufacturing cost and excellent performance, making automobile engines achieve breakthroughs in light weight, energy saving, environmental protection and manufacturing costs. Engine valve chamber covers, intake manifolds, oil pans, etc. Shells, small gasoline engine camshafts, rocker arms, oil pumps, water pumps, gearbox covers, etc. are made of nylon materials. The plasticization of automobile engines has become an inevitable development trend of the automobile industry. With the rapid development of automotive engineering plastics for decades, the weldin...

AI Technical Summary

Problems solved by technology

[0003] At present, the welding fixtures on the market basically adopt the structural method of digging holes in the inner cavity to avoid them. The welding fixtures basically do not have the functions of adjustability and product contour repositioning, which leads to long debugging time of welding fixtures and low pass rate of products. Can not meet customer needs
