Embodiment Construction

[0022] Figure 1 shows a part of a thin-walled component 2a with a visible side 4a (outer side) and an inner side 6a. A fastening cap 10a with fastening elements 12a in the upper end region is mounted on the inner side 6a of the component 2a in the fastening region 8a.

[0023] In particular, the thin-walled member 2a is a housing, however, as previously stated, other thin-walled members are also conceivable.

[0024] The term "fixing cap" is understood to mean any columnar structure protruding from the inner side 6 a of the component 2 a in the mounted state. In the representative embodiment, the retaining shield 10a is comprised of a sleeve-like body 14a having an annular cylindrical outer surface and an annular cylindrical inner surface. It can be understood that a housing with a large volume or a component with a large surface has a plurality of such fixing caps for fixing or connecting the component 2 a to other components. The geometry as well as the dimensions, especia...

Abstract

A method is described for producing a fastening arrangement of a column-shaped fixing dome of synthetic material on a thin-walled component of synthetic material, for example, a housing. The fixing dome and the thin-walled component are produced separately from each other. Here, a fastening element is integrated in the fixing dome, and an end of the fixing dome is formed as a joining section. In addition, on the inner side of the component, a joining section is built that is matched to the joining section of the fixing dome, in order to build a join connection with said join section for positioning the fixing dome on the component. The join section of the component and / or the join section of the fixing dome are now wetted with an non-curing adhesive.; Subsequently, the component and the fixing dome are joined for producing the join connection and through light curing of the adhesive are fixedly connected together.

Description

technical field [0001] The invention relates to a method for producing a cylindrical fixing cover fastening device of synthetic material on a thin-walled part of synthetic material, and a fastening device. Background technique [0002] In order to fasten thin-walled plastic components, such as housings of vacuum cleaners, lawn seeders or the like, so-called fastening caps are formed on the inside of the component during injection molding of the thin-walled component. Such a fixed cover has a height, for example 30 to 150 mm. In a further manufacturing process, metal fixing parts having the shape of eg nuts or bolts are inserted into the fixing housing. During the above manufacturing process, the following problems occurred: [0003] In the case of unfavorable wall thickness ratios of the thin-walled components and of the fastening cap, so-called sink marks, which are often unacceptable, can result on the visible side of the housing opposite the inner side. [0004] Since ...
