Portable stress wave riveting vibration attenuation reinforcing rod

Abstract

The invention discloses a portable stress wave riveting vibration attenuation reinforcing rod. A cylinder body of a damping cylinder is connected with a front cylinder cover through an ejector rod supporting base, the ejector rod supporting base is fixedly connected to a connecting plate, the connecting plate is fixedly connected to a robot flange, and a hollow sleeve is arranged in the ejector rod supporting base; the two ends of an ejector rod are sleeved with an ejector rod positioning nut and an ejector rod pre-tightening spring respectively, and the ejector rod and an absorbing rod make coaxial contact; the absorbing rod is installed in the front end of the cylinder body, a sinking bar is installed in the rear end of the cylinder body, a spring hole is formed in the sinking bar, a reset spring is installed in the spring hole, the reset spring is sleeved with a spring sleeve, and the spring sleeve is pressed against the absorbing rod; the sinking bar is connected with a rear cylinder cover sequentially through a plurality of sets of spring damping components and adjusting elastic components, and the rear cylinder cover is fixedly connected to the connecting plate. The portable stress wave riveting vibration attenuation reinforcing rod is high in anti-impact performance, light in weight, convenient to fix and hold, simple in design and convenient to adjust; due to momentum conversion and buffering, the rigidity requirement for a reinforcing rod carrier is lowered; due to the fact that the portable stress wave riveting vibration attenuation reinforcing rod can automatically return to the original position, the repeated positioning accuracy is guaranteed; the portable stress wave riveting vibration attenuation reinforcing rod has the vibration isolation protection function on the reinforcing rod carrier.

Description

technical field [0001] The invention relates to a vibration-damping top handle in the field of mechanical manufacturing and assembly, and relates to a portable stress-wave riveted vibration-damping top handle. Background technique [0002] The huge number of rivets in the aircraft requires the riveting equipment to have the smallest possible riveting cycle, the largest possible riveting power and the highest possible level of automation. In order to overcome the drawbacks of manual pneumatic hammer riveting, improve the quality of riveting, enhance the safety and reliability of aircraft, prolong the service life of aircraft, reduce the intensity of manual labor, and reduce the cost of aircraft manufacturing, the world's aviation developed countries have invested heavily in the research of aircraft automatic assembly technology. Portable and fixed riveting machines, stress wave riveting guns and other advanced automatic riveting equipment have been developed successively. Th...
