Abstract

0링의 전체 둘레를 테이퍼가이드면을 슬라이딩시켜서 조금 축경(縮徑)시키고, 작업편 구멍의 내주면과 바닥면 사이로 탄압감합시키면, 0링에 비틀림 남아 구멍으로부터 튀어나오는 경우가 있다.When the taper guide surface is slid slightly around the entire circumference of the zero ring, and a compression fit is performed between the inner circumferential surface and the bottom surface of the work piece hole, the ring may be twisted in the zero ring and protrude from the hole.

본 발명은 척부재(4)의 테이퍼가이드면(5)에 끼워진 0링(1)을 선행가압부재 (6)와 후행가압부재(7) 2단계로 나누어 축경시키서 작업편(2) 구멍(3)에 탄압감압시키는 것으로, 먼저 선행가압부재(6)로 0링(1)의 직경방향 대칭 2개소의 원호부분 (1a)을 가압하여 구멍(3)의 바닥면까지 밑으로 누루고, 다음에 후행가압부재(7)로 0링(1)의 나머지 원호부분(1b)을 밑으로 누르며, 구멍(3)의 바닥면에 가압한다. 후행가압부재(6)의 선단부에는 스프링부재(8)를 통해 선행가압부재(7)를 돌출시켜서 삽입하고, 후행가압부재(6)를 공통의 실린더(8)로 전진시킴으로써, 양 가압부재(6) (7)를 선행과 후행의 2단동작을 시킨다.According to the present invention, the zero ring (1) inserted into the tapered guide surface (5) of the chuck member (4) is divided into two stages of the preceding and the subsequent pressing members (6) and the following pressing member (7) to reduce the diameter of the work piece (2) hole ( 3) pressure reduction, first press the circular arc portion (1a) of the two radial symmetry of the 0 ring (1) with the preceding pressure member (6) and press down to the bottom surface of the hole (3) The remaining circular arc portion 1b of the 0 ring 1 is pressed downward with the trailing pressure member 7 and pressed to the bottom surface of the hole 3. Both pressing members 6 are inserted into the leading end of the trailing pressing member 6 by protruding the preceding pressing member 7 through the spring member 8 and advancing the trailing pressing member 6 to the common cylinder 8. ) Perform (2) two steps of preceding and following.

Claims

The outer circumference of the zero ring is inserted into the chuck member which can be opened and closed, and the zero ring is pressurized by a pressure member embedded in the chuck member so as to be movable relative to the chuck member, and a tapered conical tapered guide formed on the inner surface of the tip opening of the chuck member. In the zero ring attaching method in which the zero ring slides toward the tip to reduce the diameter of the ring, and the zero ring is transferred from the tapered guide surface to the workpiece hole by the pressing member, and the pressure ring is pressed against the inner circumferential surface of the hole. The pre-pressure member and the trailing-down member pressurize two circular symmetrical parts of the zero ring in the radial direction, and press the two circular symmetrical arc parts of the zero ring inserted into the chuck member from the preceding pressure member. Press the bottom surface of the hole, and then apply the remaining two circular arcs of the radial symmetry of the zero ring to the bottom surface of the workpiece hole by the trailing pressure member. 0 ring attachment method characterized in that the pressing.

The outer circumference of the zero ring is inserted into the chuck member, and the zero ring is pressurized with a pressure member embedded in the chuck member so as to be movable relative to the chuck member, and the tapered conical tapered guide surface formed on the inner surface of the tip opening of the chuck member is pressed. In the zero ring attachment device which slides the zero ring to reduce the diameter, and transfers the zero ring from the tapered guide surface to the workpiece hole by the pressing member, and press-fits the inner peripheral surface of the hole. Driving source for dividing into two parts of the radially symmetrical circular arcs, the preceding and subsequent pressing members, and connecting the preceding and second pressure members to the trailing pressure member through the spring member, and moving the trailing pressure member relative to the chuck member. By the drive source, the trailing press member and the preceding press member are integrally advanced toward the opening end of the chuck member, The two circumferential arc portions of the zero ring fitted to the chuck member by the ash are pressed to the bottom surface of the workpiece hole, and the spring member is then compressed while advancing the trailing pressure member and rest of the radial symmetry of the zero ring. A zero ring attachment device, characterized by pressing two circular arc portions on the bottom surface of the workpiece hole.

A carrier for horizontally aligning and carrying a large number of zero rings, a pusher for lifting one zero ring conveyed at the leading end of the carrier with a forward stroke from the carrier, and a zero ring lifted by the pusher. An outer unit is provided with an opening / closing chuck member of the attaching unit and an attaching unit including the preceding and following pressurizing members according to claim 2 embedded in the chuck member so as to be movable relative to each other. A zero ring attachment device, which moves to the top position and pushes the zero ring fitted to the chuck member into the work piece hole by the preceding and following pressing members.
