Abstract
The present invention relates to a hand held rivet bucking tool having a vibration dampening assembly including a visco-elastic polymer. The bucking tool features a dolly disposed within a housing and a vibration dampening assembly disposed therebetween. The visco-elastic polymer portion of the vibration dampening assembly absorbs and dissipates the vibration energy resulting from impacts received and delivered by the dolly. A second embodiment of the invention features a quick change dolly which can readily be removed from the housing so that a particular dolly can be used in conjunction with a particular rivet to be installed.
Claims6
A bucking tool, comprising:
- a housing having an interior chamber;
- an impact receiving member slidably received in said interior cavity, said member having a first end with an externally exposed impact-receiving surface and a second end terminating in a stem within said cavity;
- and
- a cylindrical mass of visco-elastic energy dissipative polymer bonded around said stem, said mass defining an outer surface and circular edge oriented in opposed relation from said impact-receiving surface, said edge being retained within said interior cavity, causing said stem to move within and stretch polymer as to dissipate at least a portion of the vibration energy associated with an impact received by said member.
