Automatic fin folding device

Abstract

The invention relates to an automatic folding fastening system, in particular to an automatic fin folding device. The automatic fin folding device comprises an installation base, a fin angle positioning unit, a fin stripping follow-up unit, a fin folding driving unit, a fastening tool grabbing unit, a folded fin anti-deformation mechanism and an external shaft, wherein the fin angle positioning unit, the fin stripping follow-up unit and the fin folding driving unit are arranged on the installation base. The fin angle positioning unit is used for positioning the angle of a fin on a missile body. The fin stripping follow-up unit is used for positioning the fin and following the fin to move. The fin folding driving unit is used for driving the fin to be folded. The fastening tool grabbing unit and the folded fin anti-deformation mechanism are arranged on the external shaft. The folded fin anti-deformation mechanism is used for holding the folded fin. The fastening tool grabbing unit is used for grabbing a fastening tool. By means of the automatic fin folding device, the folding angle precision of the fin can be ensured, the uniformness of stress applied to the fin in the folding process is ensured, and an oil paint layer of the fin is prevented from being damaged in the folding process.

Description

technical field [0001] The invention relates to an automatic closing and fastening system, in particular to an automatic closing device for flaps. Background technique [0002] At present, the closing and assembly of domestic missile stabilizer fins is mostly semi-automated and requires manual assistance, especially the two steps of the anti-deformation mechanism of the closed fins and the fastening tooling are completely manual. This closing assembly method has the following disadvantages: first, the angle positioning of the fins is manually operated when the product is placed, which increases the labor intensity of the operator; second, the closing drive mechanism is driven by a three-phase asynchronous motor, which cannot guarantee the angular accuracy of closing , nor can it ensure that the wings are evenly stressed during the closing process, which is easy to cause damage to the wings; thirdly, after closing, the anti-deformation mechanism of the wings and the fastening...

Problems solved by technology

This closing assembly method has the following disadvantages: first, the angle positioning of the fins is manually operated when the product is placed, which increases the labor intensity of the operator; second, the closing drive mechanism is driven by a three-phase asynchronous motor, which cannot guarantee the angular accuracy of closing , nor can it ensure that the wings are evenly stressed during the closing process, which is easy to cause damage to the wings; thirdly, after closing, the anti-deformation mechanism of the wings and the fastening tooling are taken by multiple people, and the fastening tooling cannot be guaranteed. The relative positional relationship with the fins when taking them is easy to cause the paint layer of the fins to fall off

[0003] In the field of missile production and assembly in China, there is no device for automatically closing the stabilizer fins. The current operation method cannot meet the requirements of missile body assembly automation and safety.
