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.

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.

An apparatus, system and method for providing an o-ring gripper. The embodiments may include an end effector, comprising: a housing; a movable stripping bar mechanically associated with the housing; a plurality of modules at least partially within the housing; and at least two interleaved angular jaws, wherein each of the at least two jaws provides at least two of the at least four fingers, and wherein an increase in angle between the at least two jaws effects an expansion of an area bounded by each of the at least four fingers; wherein a movement of the stripper bar distally from the housing strips the o-ring from the retention groove for placement.

In a flexible ring fitting device 1, a flexible ring disposition mechanism includes at least two ring support members 411 and 412 disposed relative to each other and movable so as to be separated from each other. Notches 4113 and 4123 recessed in a direction in which the two ring support members 411 and 412 are separated from each other are formed along surfaces 4114 and 4124 of the two relative ring support members 411 and 412 in the relative surfaces 4114 and 4124 of the two ring support members 411 and 412. A flexible ring R is fitted into an annular groove G of a workpiece W by a workpiece disposition mechanism moving in one direction along with the workpiece W.

A ring installation device for installing a ring to a part includes an inner mandrel which is tapered in order to expand the ring. An outer mandrel is tubular such that the inner mandrel is received within the outer mandrel and such that the inner mandrel is moveable within the outer mandrel along an axis. A ring stripper is tubular such that the outer mandrel is receive within the ring stripper and such that the outer mandrel is moveable within the inner mandrel along the axis. The inner mandrel is moveable along the axis relative to the outer mandrel and the ring stripper from an inner mandrel first position to an inner mandrel second position. The outer mandrel is moveable by the inner mandrel along the axis relative to the ring stripper from an outer mandrel first position to an outer mandrel second position.

Disclosed is a wheel airtight rubber ring press-fitting device, consisting of a frame, first servo motors, ball screw pairs, first guide rails, a first cylinder and the like. The device may be used for automatic continuous production. The central axis of an airtight rubber ring coincides with the central axis of the outer rim of a wheel, so that the positioning precision is improved, and high-precision press-fitting is realized. Through cyclic switching of double manipulators, the press-fitting feeding time is nested, the press-fitting cycle is shortened, and the working efficiency is improved.
