A piston ring is assembled into a groove of a piston by pushing the piston ring out of a front end of a guide member. The piston ring is mounted on an outside of the guide member which has a diameter larger than an outside diameter of the piston. The pushing is carried out while maintaining a clearance which allows for the piston ring to undulate. This clearance is formed between a front end of the guide member and a plane including a groove surface which lies away from the front end of the guide member. The apparatus for assembling a set oil ring into a piston ring groove of a piston has a guide member which is larger in diameter than an outside diameter of the piston, pushing device for pushing, in sequence out of a front end of the guide member, a spacer ring and a pair of side rail rings, a restricting member which is movable back and forth in a radial direction of the guide member and which can be placed with a clearance to be formed to open into that groove portion which is formed between that groove surface of the piston ring groove which is closer to the guide member and the spacer ring assembled into the piston ring groove.

Method of assembling piston ring and method of assembling set oil ring

An assembly machine including a drive unit and an assembling unit removably coupled to the drive unit so as to be driven by the drive unit to assemble an assembly such as a torque converter case with an assembly part such as a valve body unit. The machine further includes an assembly part conveyance means for supply the assembly part, an assembling unit housing means for housing a plurality of assembling units, and a changeover conveyance means. The assembly part is conveyed from the assembly part conveyance means to the assembling unit by the changeover conveyance means. At the time of the change of the type of the assembly, the assembling unit is removed from the drive unit and conveyed onto the changeover conveyance means and the direction of conveyance of the changeover conveyance means is then changed over to convey the assembling unit into the assembling unit housing means, another assembling unit housed in the housing means is conveyed out of the means onto the changeover conveyance means, and the direction of conveyance of the changeover conveyance means is then changed over again to convey the other assembling unit to the drive unit.

Assembly machine

A replaceable gang head machine tool comprising a working unit having a driving motor mounted on a slide table adapted to be driven forwardly and rearwardly and an annular rail disposed on the machine base and carrying a plurality of gang heads adapted for being driven by an index table to selectively place a gang head in an operative position. A stockyard extends longitudinally adjacent the machine base and has a longitudinally extending runway guidably supporting a carrying truck for movement therealong and a plurality of replacement gang heads are disposed on the stockyard along the length thereof so that the replacement gang heads can replace the heads disposed on the annular rail by the carrying truck.
