Definitions
- the present invention relates to a device for manually assembling a piston ring (a top ring, a second ring, an oil ring, and a side ring are collectively referred to as a piston ring in the present specification) into a groove formed in a piston.
- a device disclosed in Patent Document 1 is known as a device for automatically assembling a piston ring into a ring groove on the outer periphery of a piston, and a device disclosed in Patent Document 2 as a device for manually assembling the piston ring.
- Patent Document 1 a cap for setting a piston is attached to the upper end of four guide rods, and a ball screw (screw screw) rotated by a stepping motor is arranged in parallel with the guide rod, and the ball screw is rotated.
- a plate that moves linearly according to the above is provided outside the four guide rods, and the piston ring loaded outside of the four guide rods is pushed up by the rise of the plate, and the piston expands around the outer periphery of the cap.
- An apparatus is disclosed in which one piston ring is dropped into a ring groove on the outer periphery.
- Patent Document 2 discloses that a ball screw is disposed outside of a horizontally placed guide sleeve in parallel with the guide sleeve, an arm of a moving member is screwed into the ball screw, and the ball screw is rotated by operating a handle.
- the moving member moves along the guide sleeve, and the piston ring loaded on the outside of the guide sleeve is assembled into the ring groove on the outer periphery of the piston by the moving member.
- Patent Document 1 JP-A-7-266151, paragraphs (0027) and (0038), FIG.
- Patent Document 2 Japanese Utility Model Laid-Open No. 51-31899, page 6, line 17 to page 7, line 4
- a screw screw is arranged outside a guide member (guide sleeve or guide rod), so that a compact device cannot be achieved as an apparatus.
- the piston ring can be pushed up by a fixed amount by the stepping motor, so that the piston ring can be supplied one by one to the ring groove. If the thickness of the piston ring changes due to a model change, etc., it cannot be easily handled.
- An object of the present invention is to provide a compact manual assembly device for a piston ring, which can reliably cut out one piston ring at a time.
- the present invention provides a piston ring assembling device, a guide cylinder in which piston rings are stacked and loaded on the outer periphery, and a piston set cap detachably attached to a distal end portion of the guide cylinder.
- a lift member slidably disposed on the outer periphery of the guide cylinder and connected to the nut member, and the screw screw is rotated in one direction by operating a handle via a one-way clutch.
- the entire apparatus can be made compact and the occupied area can be reduced. Also, it is possible to reliably cut out one piston ring at a time.
- the handle can be switched between an idle position and a transmission position via a one-way clutch by a switching mechanism, and a square hole for rotating the cap at the time of attachment and detachment is provided at the bottom of the piston setting cap.
- a square hole for rotating the cap at the time of attachment and detachment is provided at the bottom of the piston setting cap.
- the piston ring assembling apparatus of the present invention is compact and can assemble the piston ring one by one into the ring groove surely with a small amount of force. Ring loading is easy.
- FIG. 1 is a front view of a device for assembling a piston ring according to the present invention, with a portion cut away.
- FIG. 7 A view similar to FIG. 1 illustrating an operation of returning a lifting member to an original position.
- FIG. 1 is a partially cutaway front view of a piston ring assembling apparatus according to the present invention
- Fig. 2 is an overall view of a guide cylinder
- Fig. 3 is an overall view of a screw screw
- Fig. 4 is a nut member and a lifting member.
- FIG. 5 is a view from above of FIG. 4, and
- FIG. 6 is a view of the handle from below.
- reference numeral 1 denotes a base, on which the lower end of the guide tube 2 is fixed.
- a female screw portion 3 is engraved inside the upper end of the guide tube 2, and a male screw portion 5 of a cap 4 is screwed into the female screw portion 3.
- the cap 4 is provided with a square hole 4a in the center, and a jig is inserted into the square hole 4a and rotated to be attached to and detached from the guide cylinder 2.
- the outer periphery of the upper half of the cap 4 has a tapered shape that expands in diameter upward.
- a recess 6 is formed on the upper surface of the cap 4, and the piston 7 is set in the recess 6.
- the depth of the concave portion 6 is set such that the ring groove formed on the outer periphery of the piston 7 is set immediately above the upper end of the cap 4 with the piston 7 set. Therefore, replace the cap 4 according to the dimensions of the piston.
- the guide cylinder 2 has slits 8 and 8 formed at positions facing each other along the axial direction (vertical direction) of the cylinder, and a screw screw 9 is further arranged in the guide cylinder 2.
- the screw screw 9 is rotatably supported at the lower end of the guide cylinder 2 via a bearing or the like, and is provided with a hexagonal column-shaped engaging projection 10 at the upper end thereof. It faces hole 4a.
- a manual operation unit 12 is connected to a lower portion of the screw 9 via a coupling 11.
- the manual operation unit 12 has a handle 14 attached to a one-way clutch 13 and pushes the one-way clutch 13 to a driving force transmitting position by a spring 15 in a normal case.
- stoppers 16 and 17 are provided below the base 1 to limit the rotation limit of the handle 14. These stoppers 16 and 17 can be adjusted in position, so that the thickness of the piston ring can be easily changed as described later.
- a nut member 18 is screwed to the screw 9.
- the nut member 18 is housed inside the guide tube 2, and a part 19 of the nut member 18 penetrates through the slit 8 formed in the guide tube 2 and projects to the outside of the guide tube 2.
- the elevating member 20 includes a plate portion 21 and a tube portion 22 and is slidable along the guide tube 2.
- the upper surface of the plate portion 21 is flush with a part 19 of the nut member 18, and
- the upper surface of the part 21 supports the lower ends of a predetermined number of piston rings 23 loaded on the outer periphery of the guide cylinder 2.
- the handle 14 is brought into contact with one of the stoppers 16 in the state of FIG. 1, that is, in a state where a predetermined number of piston rings 23 are loaded on the outer periphery of the guide cylinder 2 and the piston 7 is set in the cap 4.
- the contact force is also rotated to a position corresponding to the other stopper 17.
- the screw 9 rotates by a predetermined amount, and the nut member 18 and the elevating member 20 move upward according to the amount of rotation.
- the one-way clutch 13 and the nozzle 14 are moved from the driving force transmission position to the idle position with the piston 7 removed, as shown in FIG. Then, the socket 26 of the jig 25 is engaged with the protrusion 10 of the screw 9 via the square hole 4a of the cap 4, and the screw 9 is reversed by using the jig 25. Rotate in the direction. At this time, since the one-way clutch 13 and the nozzle 14 are in the idling position, the position of the handle 14 does not change even if the screw 9 is rotated.
- the piston ring assembling apparatus according to the present invention requires no power and is easy to operate. Therefore, it is extremely effective, for example, in a site for small-lot production of many models.
