An automated grommet installer and methods of installing a grommet. The installer and methods are capable of seating a grommet in an aperture of a window and facilitating correct alignment of the grommet within the window. Grommets are used to support and seal around a window wiper attached to a window. Typically, grommets are asymmetrical to match the curvature of the window. Embodiments of the described installer maintain grommet orientation while inserting the grommet in the window, quickly and efficiently installing the grommet. In embodiments the installer includes a system for identifying an incorrectly loaded grommet prior to installation and alerting an operator. In other embodiments, the installer includes a positioner that positions the grommet proximate to the window for installation and a gripper having one or more fingers reach through the window aperture, engage the grommet, and draw it into position, seated in the window.

A robotic grommet installer includes a robotic arm and an installation unit. The installation unit includes a rotary grommet holder rotatively coupled to the robotic arm and an installer coupled to the robotic arm. The rotary grommet holder includes a plurality of grommet chambers spaced circumferentially about a rotational axis of the rotary grommet holder. Each grommet chamber of the plurality of grommet chambers is configured to hold a plurality of grommets. The installer is configured to retrieve a grommet from the rotary grommet holder, wherein the rotary grommet holder is configured to rotate to align the installer with an available grommet positioned within one of the plurality of grommet chambers.

An elastic sealing ring expanding apparatus includes a base on which a plurality of posts are disposed, an assembly platform supported on the base by the posts, a plurality of rods movably mounted on the assembly platform, and a driving device mounted on the base. The driving device is configured to drive the rods to move from a center of a rectangle toward a plurality of corners of the rectangle along a plurality of straight paths, expanding an elastic sealing ring sleeved on the rods into a rectangular ring with a predetermined length-width ratio.

In a state where a pair of protrusion portions of a ring portion is clamped by front end engagement portions of a pair of claw members (71) (72), the front end engagement portions of the pair of claw members are swung in a direction approaching each other about a pivotal supporting portion (80). A sliding body (77) slides with the contact of the front end engagement portion to the ring portion or to the protrusion portion thereof so as to follow a radial and circumferential displacement of the protrusion portion accompanying a diameter reduction of the ring portion.

A joint assembly and disassembly tool and method of using the tool to assemble and disassemble a joint assembly. The tool includes a first member having a first member aperture extending from a first side to a second side of the first part. Additionally, the tool includes a second member having a second member aperture extending from the first side to the second side of the second member. At least a portion of a retention member is connected to at least a portion of the first member of the tool. A first actuation mechanism is drivingly connected to a pressure plate which is received and/or retained within at least a portion of the first member aperture. Additionally, a second actuation mechanism is drivingly connected to a force application member which is selectively received within at least a portion of the second member aperture.

A collar fastening system that includes a collar fastening tool, and a collar loading assembly coupled to the collar fastening tool. The collar loading assembly includes a loading arm that rotates into multiple positions and a holding member coupled to the loading arm. The loading arm positions the holding member between a loading position and an unloading position. The holding member includes an arcuate side wall and a vacuum opening defined in the arcuate side wall. The holding member receives a collar when at the loading position, and selectively holds the collar against the arcuate side wall with a retaining force provided by a vacuum applied via the vacuum opening. The loading arm provides the collar to the collar fastening tool when at the unloading position.

A piston ring installation jig is to be used when installing a piston ring having a ring gap in a ring groove formed in an outer peripheral surface of a piston. The piston ring installation jig includes a main body including a groove. The main body has in a semi-cylindrical shape surrounding the outer peripheral surface of the piston. The groove has a substantially semicircular arc shape, and is formed in an inner peripheral surface of the main body in a region corresponding to the ring groove of the piston. A portion of the piston ring in a circumferential direction is inserted into the groove. The groove has a shape of an arc of a circle which has a circle center biased more to an outer peripheral side of the main body than a circle center of an inner peripheral surface of the main body.

The present application discloses a fitting apparatus (100) for fitting a sealing member (110) onto a solder paste nozzle (230), the sealing member having a sealing member mounting hole (112), and the fitting apparatus comprising: a support plate (116); at least two first power sources (101, 102, 103, 104); at least two insertion members (121) and a second power source (105). By controlling the driving directions and driving sequence of multiple power sources, the fitting apparatus of the present application completes the work of expanding the sealing member mounting hole in a mechanical fashion; an operator then only needs to pass the base plate of the nozzle through the sealing member mounting hole in order to complete the fitting of the sealing member to the nozzle, so the operation is convenient and saves manpower.
