Supporting plate nut riveting assisting device

Abstract

The invention discloses a supporting plate nut riveting assisting device. The supporting plate nut riveting assisting device comprises a front machine frame, a rear machine frame, a tight-and-loose handle, elbow ejector iron and a locking nut. The front machine frame comprises a main body and a large lug, the rear machine frame comprises a cylinder body and a mounting seat; the working end of a riveter sequentially penetrates through the cylinder body and the main body and is connected to the locking nut; a mounting plate is disposed in parallel with the large lug, and the large lug and the mounting plate are separately provided with a cavity and a mounting plate correspondingly; and one end of the tight-and-loose handle is installed at the top of the mounting plate in a hinged mode; the elbow ejector iron includes an assisting end and a driving end, wherein the assisting end is connected with the driving end through a bend cylinder body; and the driving end of the elbow ejector iron sequentially penetrates through a mounting hole, the mounting plate and is connected with a convex lug in a sliding mode. The supporting plate nut riveting assisting device reduces the complexity and difficulty of the riveting of a workpiece to be machined, improves the stability of the rapid forming and riveting quality of rivets, greatly reduces the difficulty and complexity of the riveting, andmeets the riveting demands of high quality and high efficiency in a space limited area.

Description

technical field [0001] The invention belongs to the technical field of tool design, and in particular relates to an auxiliary device for riveting a pallet nut. Background technique [0002] During the assembly process of small aircraft, the assembly of connecting parts involving a large number of detachable covers, protective covers, etc., especially in the closed corner area with a small space (that is, the profile The angle formed by parts such as belt plates and the main body parts of the fuselage is less than 90°), and the portable riveting machine used cannot be used in a large area due to the limitation of the working position. Therefore, the current method for riveting in the narrow closed angle area is: two One person cooperates with the pneumatic rivet gun and the top iron for riveting, one person operates the rivet gun to rivet, and the other uses the special top iron to top the rivets, because the special top iron is limited by space, its working surface is small,...

Problems solved by technology

[0002] During the assembly process of small aircraft, the assembly of connectors involving a large number of detachable covers, protective covers and other parts is involved, especially there are a large number of bracket nuts on profiles and strip plates And the riveting part of the rivet is in the closed angle area with narrow space (that is, the angle formed by the profile, strip plate and other parts and the main body part of the fuselage is less than 90°), the portable riveting machine used cannot be used in a large area due to the limitation of the working part, so , the current method of riveting in the narrow closed angle area is: two people cooperate with the pneumatic rivet gun and the top iron for riveting, one person operates the riveting gun to rivet, and the other uses the special top iron top rivet, because the special top iron is limited by space , the working surface is small, light in weight, and the riveting time is long, which can easily damage the surface of the parts and damage the rivet head, resulting in difficulties in forming the rivet head, unstable quality, low production efficiency, high labor intensity, and serious waste.
