Problems solved by technology

As an important riveting assembly link of the fin shaft seat assembly, there are many deficiencies in the existing technology: the riveting positioning structure is simple, it is only composed of a simple pin shaft and a support block, the rigidity is poor, the positioning accuracy is low, and the riveting operation experience is required Higher, so the accuracy of the fin shaft seat is poor, and the qualified rate is low. The coaxiality of the shaft hole of the upper shaft seat and the lower shaft seat is φ0.2mm, the distance is 0.2mm, and the parallelism between the shaft seat and the shaft base is 0.2mm , the pass rate of the product is about 75%

Embodiment

[0016] see figure 1 , a positioning riveting device for a vane shaft seat assembly, mainly comprising: a base 1, a positioning block 2, a limit block 3, a fixed shaft 4, a pressure plate assembly 5 and a lifting ring 6, wherein the base 1 adopts a ring structure , is the positioning base of the whole device. The center of the base 1 is designed with a circular step structure, which is the positioning reference of the shaft base parts in the fin shaft seat product; 1 to achieve fastening, and a plurality of them are evenly distributed along the axis of the base 1. There are six positioning blocks 2 in this embodiment. The position is fixed to ensure the accuracy of the distance between the upper shaft seat and the lower shaft seat; the limit block 3 is also positioned and fastened on the base 1 through cylindrical pins and screws, and the limit block 3 is set on the left side of the positioning block 2 and carried out in the same direction as it. The angle is evenly distribute...

Abstract

The invention discloses a flap shaft seat assembly locating and riveting device. The flap shaft seat assembly locating and riveting device comprises a base, locating blocks, limiting blocks, fixing shafts, pressing plate assemblies and hanging rings. The three or more locating blocks are uniformly and fixedly connected to the base. The limiting blocks are also uniformly and fixedly connected to the base. Each limiting block is arranged at one side of the corresponding locating block, and the limiting blocks and the locating blocks are uniformly distributed at the same angle in the same direction. A locating notch is formed in the other side of each limiting block. Each fixing shaft is fixedly connected to the corresponding locating block. The pressing plate assemblies and the locating blocks are uniformly distributed on the base in an equal-number and equal-angle manner. The number of the hanging rings is a half of that of the locating blocks, and the hanging rings are fixedly and uniformly distributed on the base. By means of the flap shaft seat assembly locating and riveting device, riveting precision of flap shaft seat assembly products is improved; the qualification rate of theproducts is increased; labor intensity of product clamping and locating is lowered; and meanwhile, compared with the prior art, precision and rigidity of the device are greatly improved.

Description

technical field [0001] The invention relates to a special device in the field of aerospace technology, in particular to a positioning riveting device for a vane shaft seat assembly. Background technique [0002] The fin shaft seat assembly is mainly used to install the movable fins of aerospace vehicles. It is an important part of the attitude control of a special aircraft. It is mainly completed by riveting assembly. The accuracy of the riveting assembly is to evaluate the flight reliability of this type of special aircraft. One of the key indicators, the poor riveting assembly accuracy of the wing shaft seat assembly is likely to cause the steering of the flying movable wing to get stuck or stuck, resulting in the failure of the flight control of aerospace products, causing safety accidents, and even causing major economic losses and casualties . [0003] The fin shaft seat assembly is mainly composed of the shaft base, the upper shaft seat and the lower shaft seat. The u...
