Problems solved by technology

The downside is that when the collar bolt is tilted, it is still easy to pull it out of the through hole
Also, the spring elements in the through holes add to the cost of the part
In addition, the elastic element must be pre-positioned in the through hole, which also increases the pre-assembly time and pre-assembly effort

Embodiment Construction

[0024] Figure 1 to 4 A cross-sectional view of the fixing device 1 in accordance with the present invention is shown. The fixing device 1 is provided as securing the member 2 to a pairing member - not shown here. The fixing device 1 thus includes a fixing portion 4 having a ring bolt 3 and a member 2. A through hole 5 is formed in the fixing portion 4, and a ring bolt 3 is arranged in the through hole. Belt bolt 3 thus has a thread 6 (shown in this only), the bolt head 7 and the circumferential collar 8 formed thereon. An inner radial stop protrusion 9 and an internal radial clamp projection 10 are formed in the through hole 5. The clamping projection 10 is positioned relative to the stop projection 9, and offset from the stop projection 9 in the axial direction.

[0025] The fixing device 1 is pre-assembled in accordance with the method 11 according to the present invention. according to figure 1 First, the bond bolt 3 is inserted into the through hole 5 of the fixing portion 4 ...

Abstract

The invention relates to a fixing device (1) for fixing a component (2) to a counterpart. The fixing device (1) comprises a ring bolt (3) having a thread (6), a bolt head (7) and a circumferential collar (8) formed between them. The fixing device (1) also comprises a fixing portion (4) of the part (2), in which a through hole is formed including a radial stop protrusion located inside. The ring bolt is inserted into the through-hole in the insertion direction, and in the pre-assembled state, the collar of the ring bolt is supported axially in the pulling-out direction on the stop projection of the through-hole. According to the invention, a clamping projection is formed in the through hole, which is located inside, diametrically opposite to the stop projection and axially offset from the stop projection in the insertion direction. In the pre-assembled state, the collar is supported axially in the insertion direction on the clamping projection, so that the collar bolt is clamped between the stop projection and the clamping projection. The invention also relates to a component comprising a fixing device and a method for pre-assembling the fixing device.

Description

Technical field [0001] The present invention relates to a fixing device for securing the member to a pairing member. The invention also relates to a method for pre-assembling a fixture. Background technique [0002] A fixed device that secures the component to a pair of parts using a loop bolt. Components and pairs including a loop bolt are often manufactured and transported separately. As described in, for example, in DE 10 2015 220 370 A1, a ring bolt can be prefeded in a component. Here, in the through hole of the ring bolt insert member, the collar bolt and the stop projection are axially engaged in the through hole. In order to be able to guide the ring bolt, the elastic element is provided in the through hole. The elastic element is deformed when the collar is guided through the stop projection and prevents an undesirable release of axial engagement between the ring bolts and the stop projections. Thus, on the one hand, the bolt head with a loop bolt, and on the other hand,...
