Problems solved by technology

However, because the width of the entrance is too small, the hand-held rivet is easy to fall during the insertion process, and even the hand-held rivet cannot be inserted into the gap, which affects the riveting process.
The operation is extremely inconvenient and the production efficiency is also low

Abstract

The invention relates to a rivet assembly tool. The rivet assembly tool comprises a sleeve, a spring, a baffle plate, a slide block, an inner sleeve, a support rod and a stopper; the stopper is fixedly connected with the support rod; a through hole is formed in the stopper; the baffle plate penetrates through the through hole, and is inserted in the sleeve; the spring is arranged in the sleeve; the slide block is positioned on the baffle plate; an upward boss is arranged at the middle part of the slide block, and is positioned in a hole in middle of the inner sleeve; and a rivet to be mounted is arranged in the hole in middle of the inner sleeve. The whole assembly tool is convenient and fast in operation, can mount rivets with different specifications, can satisfy different position requirements of the rivets through adjusting the length of the support rod, is convenient to mount the rivets, and effectively improves the production efficiency.

Description

technical field [0001] The invention relates to a riveting tool, in particular to a rivet assembly tool, which can realize rivet assembly in a narrow gap. Background technique [0002] Rivet assembly is a relatively common process in the manufacturing process of engine hot end parts. However, in some special positions, such as the rivet assembly on the flame tube of some aero-engines, since the flame tube is composed of inner wall, outer wall and vortex, 48 rivets are evenly distributed around the outer wall of the part, and the distance between the riveting holes and the upper port on the outer wall The distance is 222.6±0.5mm. However, the width of the gap between the inner and outer walls of the flame cylinder is only 50 mm. During rivet assembly, the operator generally can only hold the rivet by hand, and directly insert it from the narrow entrance of the inner and outer walls. However, because the width of the entrance is too small, it is easy to drop the hand-held r...
