Abstract
An installation tool for application of a flexible dynamic seal such as weatherstrip to an end flange of a vehicle. It includes a rotary drive source to rotate a double-sided cam (could be three-sided as well) that pushes on a spring-loaded block changing the rotation into a linear back and forth motion. This spring-loaded block is attached to a plastic pad that is applied to the seal to transfer the motion on the seal and mimics the operator pushing the seal to install.
Claims14
A vibratory flexible dynamic seal installer tool for installation of a flexible dynamic seal piece over a flange comprising:
- a rotational drive source having a rotary shaft;
- a vibratory tool end;
- and
- a vibratory tool linkage assembly comprising a cam lobe attached to said rotary shaft and a reciprocating member engaging the cam lobe for moving the reciprocating member in response to rotation of the shaft connecting the rotational drive source to the vibratory tool end at an angle from an axis of rotation of the rotational drive source, wherein the reciprocating member has a changeable tool pad for customizing the tool to a predetermined trim piece.
A vibratory flexible dynamic seal installer tool for installation of a flexible dynamic seal piece over a flange comprising:
- a connection adapted to be connected to a rotational driving member;
- a vibratory tool end including a seal engaging member which is interchangeable for customizing the tool to a predetermined trim piece;
- and
- a vibratory tool linkage assembly connecting the rotational drive source to the vibratory tool end at an angle from an axis of rotation of the rotational drive source wherein said tool linkage assembly further comprises a cam lobe attached to a rotary shaft, including a reciprocating member engaging the cam lobe for moving the reciprocating member at a substantially 90 degree angle in response to rotation of the shaft.
A method of installing an elongated flexible dynamic seal piece on an end flange comprising:
- providing a tool which has a vibratory tool, said tool comprising a connection adapted to be connected to a rotational driving member;
- a vibratory tool end including a seal engaging member which is interchangeable for customizing the tool to a predetermined flexible dynamic seal strip;
- and
- a vibratory tool linkage assembly connecting the rotational drive source to the vibratory tool end at an angle from an axis of rotation of the rotational drive source wherein said tool linkage assembly further comprises a cam lobe attached to a rotary shaft, including a reciprocating member engaging the cam lobe for moving the reciprocating member at a substantially 90 degree angle in response to rotation of the shaft, and
- selecting and installing a seal engaging member onto the tool for customizing the tool to said predetermined flexible dynamic seal strip and,
- forcing said flexible dynamic seal strip in a direction toward the flange and onto the flange, wherein the vibratory tool has a handle at substantially a 90 degree angle to the flange.
