An object of the present invention is to provide a device for installing a retaining ring on a shaft which can reduce the labor intensity of workers. The device for installing a retaining ring on a shaft comprises an expansion assembly. The expansion assembly includes a shell. A push block is movably fixed in the shell. Two expansion members that are symmetrical left and right are arranged in front of the push block. The expansion members include expansion portions that are located outside the shell and extend outward. Rear ends of the expansion portions are expansion portion first sections. The expansion members comprise a left expansion member on the left side and a right expansion member on the right side. The left end face of the expansion portion first section of the left expansion member is a slope extending leftward from rear to front. The push plate moves in a front-rear direction so that the expansion portions of the two expansion members move left and right, respectively. A loading rod is fixed on the lower side of the shell. A front edge of a front portion of the loading rod extends outward in a circumferential direction to form a limiting bump. A compression spring is sheathed on a rear portion of the loading rod. A front end face of the loading rod is recessed inward to form an evading groove.

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.

An end effector for installing pre-molded seal caps onto fasteners comprises a cap-dispenser assembly and a cap-placement assembly. The cap-placement assembly comprises a main housing and a plunger mechanism, comprising an outer plunger housing and an inner gripper. The inner gripper is rotatable relative to the outer plunger housing between a cap-retaining configuration and a cap-releasing configuration. The plunger mechanism is selectively translatable from an extended position to a retracted position and from the retracted position to the extended position. The main housing is selectively rotatable from a cap-receiving position, in which the plunger mechanism is aligned with the seal-cap-delivery-sleeve central axis, to a cap-installing position, in which the main housing is angularly displaced from the cap-receiving position, and from the cap-installing position to the cap-receiving position.

The present application discloses an apparatus for mounting an O-ring to a work piece, which includes a body including a plurality of connecting holes for connecting a pressure source to the body; an annular groove formed on the body and adapted to receive the O-ring; and a plurality of air channels formed in the body, the plurality of air channels being in fluid communication with the annular groove and the plurality of connecting holes to provide negative pressure with the pressure source in the annular groove to suck the O-ring in the annular groove, the annular groove is coaxial with a groove formed on a surface of the work piece during the mounting so that the O-ring is dropped into the groove when the pressure source is disconnected from the body or provides positive pressure to the plurality of air channels.

The present application discloses an apparatus for separating and feeding O-rings, which includes a rotatable body including a storage portion and a separating portion; and a helix groove formed on the rotatable body across the storage portion and the separating portion, wherein a width and a depth of the helix groove are adapted to a wire diameter of a O-ring, and pitch of the helix groove on the separating portion increases along a feeding direction from the storage portion to the separating portion, wherein in response to a rotation of the rotatable body, the helix groove conveys a plurality of O-rings hanged on the storage portion to the separating portion to thereby separate the plurality of O-rings away from each other.

An apparatus for mounting an O-ring to a work piece, including: a plurality of picking components operable to move away from each other to contact and expand the O-ring to pick the O-ring or to move towards each other to release the O-ring; and a guiding component including a frustum portion arranged coaxially with a groove of the work piece, a large end face of the frustum portion arranged adjacent to an end surface of the work piece on which the groove is formed, wherein a diameter of the large end face is substantially same as an inner diameter of the groove, wherein the picking components are operable to release the O-ring onto a tapered surface of the frustum portion so that the O-ring is pushed into the groove along the tapered surface.

A system comprises a holder including a mounting feature configured to mount to a flange of a fuel injector and a block including a mounting feature configured to mount to a side of the flange that is opposite from the holder. The system includes, punch configured to pass through at least one punch aperture in the block. The punch aperture is configured to guide a tip of the punch into position to deform a c-seal seated in a seal channel of the flange. A method for using the system using the system is also disclosed.

A method for performing operations on a target workpiece including taking an operating tool unit by an industrial robot, carrying the tool unit to the workpiece, releasing the tool unit at the workpiece, moving the robot away from the tool unit, performing one or more operations on the workpiece through the tool unit while the tool unit moves with the workpiece; and retrieving the tool unit from the workpiece after the tool unit has performed the one or more operations on the workpiece. A robotic assembly for performing a method including at least one industrial robot, at least one operating tool unit, and a quick tool changer for detachably coupling the tool unit with the industrial robot including a first tool changer part arranged in the industrial robot and a second tool changer part arranged in the operating tool unit.

An outer ring (29) is first transported to an insertion point (E) in the feed device (34). At the same time, a circular blank ring (30) is brought into a starting position (P) in the feed device. The circular blank ring (29) is first aligned coaxially with respect to an axis (A) using a centering body (61). The circular blank ring moves solely radially with respect to the axis (A). The circular blank ring (30) is then inserted into the hole of the outer ring (29). During this movement, the circular blank ring is aligned coaxially with respect to the axis (A) preferably using a centering channel (54). The circular blank ring (30) carries out a superimposed movement in the axial direction (V) and in the radial direction radially with respect to the axis (A).

A method of manufacturing produces an assembled product where a ring-shaped seal is attached to a channel in an inner circumferential surface of a ring-shaped component. The method includes: a holding step that moves an engaged portion of the seal inwardly in a radial direction using a deformation member, while restricting movement of the seal in a direction parallel to an inner circumferential wall of the channel, to cause deformation so that the outer diameter of part of the seal aside from the engaged portion becomes smaller than the channel inner circumferential diameter; and an attachment step that attaches the seal to the channel by releasing the seal to restore the seal from the deformation. The attachment step includes releasing the seal by releasing engagement by the deformation member and moving the seal body inside the channel while pressing out the seal body from inside.
