Description
Technical Field
The present invention relates to an elastic ring mounting jig for mounting an annular elastic ring to an annular groove of an object.
Background
Conventionally, there is known a mounting jig for mounting an elastic ring body such as a gasket to an annular groove of an object having a circular cross section, which is configured by connecting both end portions of two plate members overlapped with each other by a fixing member, as disclosed in japanese patent laid-open publication No. 2005-256875, for example.
In the case of attaching the annular spacer to the lower end of the guide formed in a cylindrical shape using the attachment jig, the annular spacer is first inserted and disposed at the upper end of the guide, and the attachment jig is pressed from above toward the upper end so as to be positioned between one plate member and the other plate member. Accordingly, the lower end portion of each plate member abuts on the upper surface of the annular packing, and the one plate member and the other plate member move downward while being separated from each other with the guide interposed therebetween, whereby the annular packing is pushed and moved toward the lower end side.
Then, the annular packing reaches the packing attachment groove provided at the lower end of the guide by the pressing action of the attachment jig, and is elastically reduced in diameter toward the inside in the radial direction, thereby being attached to the packing attachment groove.
Disclosure of Invention
However, in the above-described mounting jig, since the annular pad is pressed by the two plate members separated from each other with the guide interposed therebetween, the annular pad cannot be pressed over the entire circumference by the plate members, and only a part of the plate members that are in contact with each other cannot be pressed. Therefore, the annular packing moves along the guide and is twisted, which causes a decrease in the moving speed of the annular packing when the annular packing is moved, and a decrease in the sealing performance when the annular packing is attached to the packing attachment groove in a state where the twisting occurs.
In addition, when there are a concave portion and a convex portion above the position where the annular packing is inserted from the packing installation groove, the annular packing cannot be smoothly moved to the packing installation groove, and the workability is deteriorated.
A general object of the present invention is to provide an elastic ring mounting jig which can prevent twisting when mounting an elastic ring, can be reliably and efficiently mounted at a desired position, and can ensure sealing performance.
The invention provides an elastic ring installation jig, which can enable an elastic ring to move along an object with an annular groove on the surface for installing the elastic ring, and the elastic ring installation jig is provided with a ring installation part and a pushing part, wherein the ring installation part is used for installing the elastic ring; the pusher abuts against the elastic ring over the entire circumference in the moving direction of the elastic ring to push the elastic ring out toward the annular groove, and the pusher pushes a part of the elastic ring located on the surface side of the object in the direction orthogonal to the moving direction.
According to the present invention, an elastic ring mounting jig for mounting an elastic ring to an annular groove of an object is configured to: having a ring mounting portion for mounting an elastomeric ring; and a pusher that is in contact with the elastic ring over the entire circumference in the moving direction of the elastic ring and pushes the elastic ring toward the annular groove, the pusher pushing a portion of the elastic ring that is located on the surface side of the object in a direction orthogonal to the moving direction of the elastic ring.
Therefore, the elastic ring can be attached to the annular groove by moving the elastic ring attachment jig to which the elastic ring is attached along the surface of the object and pushing out the elastic ring attached to the ring attachment portion by the pushing member, and the elastic ring can be attached to the annular groove by pushing a part of the elastic ring located on the surface side of the object by the pushing member, so that friction and torque generated between the inner periphery of the elastic ring and the elastic ring attachment jig can be cancelled out, and the elastic ring can be attached to the annular groove by moving the elastic ring without twisting.
As a result, the elastic ring can be reliably and efficiently attached to the annular groove of the object by the pusher, and the elastic ring can be prevented from being twisted when moving. This ensures the sealing performance of the elastic ring and enables efficient operation. In addition, even when the distance for moving the elastic ring along the surface of the object is long, the elastic ring can be attached to the annular groove without twisting.
The above objects, features and advantages should be readily understood from the following description of the embodiments with reference to the accompanying drawings.

That is, inclined portion 26 is formed inclined at a predetermined angle with respect to the axial direction (the direction of arrow A, B) of pusher 12.
The flat portion 28 is formed in a ring shape substantially orthogonal to the axial direction of the pusher 12, and is formed on the innermost peripheral side of the pressing portion 22.
Further, a stepped portion 30 that protrudes radially inward so as to be orthogonal to the inner peripheral surface of the body portion 18 is provided on the proximal end side (arrow a direction) of the pressing portion 22, and the stepped portion 30 extends from the inner peripheral surface of the body portion 18 to the inner peripheral side of the flat portion 28. In other words, the stepped portion 30 is formed substantially parallel to the flat portion 28.

The holder 14 is provided with a projection 32 projecting radially inward by a predetermined length with respect to the pusher 12 and projecting toward the front end side (in the direction of arrow B), and the outer peripheral surface of the projection 32 is provided to abut against the inner peripheral surface of the body portion 18. The holder 14 is gripped or pressed by an operator not shown when the seal ring 20 is mounted by the mounting jig 10.
The projection 32 is formed with a first recess 34 that opens at its distal end side and is recessed in the axial direction (the direction of arrow a), and a plurality of first recesses 34 are provided along the circumferential direction of the holder 14, and a base end of a spring (elastic member) 44 described later is interposed therebetween.
A plurality of bolt holes 36 are opened in the retainer 14 so as to be spaced apart from each other along the circumferential direction thereof, and in a state where the base end of the main body portion 18 of the pusher 12 abuts on the distal end surface of the retainer 14, fastening bolts 38 are inserted through the bolt holes 36 and screwed into the screw holes 24 of the pusher 12. Thus, the retainer 14 is integrally connected to the pusher 12.
The main body 16 is formed in a cylindrical shape having a small diameter with respect to the pusher 12, and has a base end facing the protrusion 32 of the holder 14, an outer circumferential surface in sliding contact with the main body portion 18 of the pusher 12, and an inner circumferential surface formed in substantially the same diameter.
In addition, the base end of the main body 16 has an annular positioning portion 40 and a plurality of second recessed portions 42, wherein the positioning portion 40 protrudes radially inward with respect to the inner peripheral surface; the plurality of second recesses 42 face the first recesses 34 of the holder 14, and the positioning portion 40 has, for example, a surface orthogonal to the axis of the main body 16. Also, the inner peripheral diameter of the positioning portion 40 is formed substantially the same as the inner peripheral diameter of the holder 14.
The second recesses 42 are formed so as to be open at the base end of the main body 16 and recessed toward the tip end side (in the direction of arrow B), the same number as that of the first recesses 34 is provided, and springs 44 are interposed between the first recesses 34 and the second recesses 42. The spring 44 is formed of, for example, a coil spring, and urges the main body 16 in a direction (arrow B direction) away from the holder 14.
On the other hand, an engagement end 46 capable of engaging with the stepped portion 30 of the pusher 12 is provided on the distal end side of the body 16, the distal end of the engagement end 46 is formed so as to be orthogonal to the axial direction of the body 16, and a mounting portion (ring mounting portion) 48 projecting further toward the distal end side (in the arrow B direction) than the engagement end 46 is provided on the inner circumferential side of the engagement end 46.
The body 16 is located on the inner peripheral side of the pusher 12, is provided to be movable in the axial direction (in the direction of arrow A, B) by a predetermined distance from a position (see fig. 2 and 3) where the engagement end 46 on the distal end side abuts against the stepped portion 30 to a position (see fig. 5C and 5D) where the base end abuts against the protrusion 32 of the holder 14, and is biased in a direction away from the holder 14 by the elastic force of the spring 44, so that the engagement end 46 is held in abutment against the stepped portion 30.
The mounting portion 48 extends in the axial direction (the arrow B direction) at a constant thickness in the radial direction, has the same diameter on the inner peripheral surface, and is disposed on the inner peripheral side with respect to the pushing portion 22 of the pusher 12. As shown in fig. 2 and 3, the mounting portion 48 is formed such that: when the engagement end 46 of the main body 16 is engaged with the stepped portion 30, it protrudes a predetermined length from the tip end (flat portion 28) of the pressing portion 22.
When the seal ring 20 is mounted on the workpiece using the mounting jig 10, the seal ring 20 is mounted and held on the outer peripheral side of the tip of the mounting portion 48 protruding from the pusher 12.
The mounting jig 10 according to the embodiment of the present invention is basically configured as described above, and next, a case where the seal ring 20 is mounted on the stator holder 60 as the object using the mounting jig 10 will be described.
First, referring to fig. 4 to 5 (D), the stator holder 60 as an object will be briefly described.
The stator holder 60 is formed in a cylindrical shape capable of accommodating a stator core (not shown) therein, has a predetermined length in the axial direction (the direction of arrow A, B), and has a flange 62 provided at its tip end for attaching the stator holder 60 to another member.
Further, the outer peripheral surface (surface) of the stator holder 60 has: a large diameter portion 64 formed on the tip end side (arrow B direction) having the flange 62; and a small diameter portion 66 formed on the base end side (in the direction of arrow a) and having a slightly smaller diameter than the large diameter portion 64. The large diameter portion 64 is formed with an annular seal groove (annular groove) 68 to which the seal ring 20 is attached at a position near the flange 62, and is also formed with another annular groove 70 at a base end side so as to be adjacent to the seal groove 68. A plurality of annular recesses 72 that are recessed radially inward are also formed in the small diameter portion 66.
That is, the outer peripheral surface of the stator holder 60 is formed with a plurality of annular grooves 70 and annular recesses 72 having uneven cross-sections, in addition to the seal groove 68 to which the seal ring 20 is attached.
Next, a case where the seal ring 20 is mounted to the seal groove 68 of the stator holder 60 using the mounting jig 10 will be described with reference to fig. 4 and 5 (a) to 5 (D). As shown in fig. 4, the mounting jig 10 is used such that the holder 14 is positioned downward and the mounting portion 48 of the main body 16 is positioned upward.
First, as shown in fig. 4 and 5 (a), the seal ring 20 is attached to the outer peripheral surface of the distal end of the attachment portion 48 of the attachment jig 10. Since the outer peripheral diameter of the mounting portion 48 is set to be slightly larger than the diameter (inner peripheral diameter) of the seal ring 20, an operator (not shown) mounts the seal ring 20 on the outer peripheral side of the mounting portion 48 while elastically deforming the seal ring 20 so as to expand the diameter. Thereby, the inner peripheral surface of the seal ring 20 is in contact with the outer peripheral surface of the mounting portion 48 over the entire circumference, and the flat portion 28 of the pusher 12 is held in contact with the tip end surface of the seal ring 20 over the entire circumference.
In detail, the flat portion 28 is in contact with only a portion located radially inside the stator holder 60 side at the tip end surface of the seal ring 20. In other words, the tip end surface of the seal ring 20 is arranged not to contact the pusher 12 at the radially outer side in the radial direction.
Next, as shown in fig. 4, the jig 10 is inserted through the stator holder 60 from the distal end side thereof to the outer peripheral side of the stator holder 60 with the stator holder 60 to which the seal ring 20 is attached as an upper side (see fig. 5 a). At this time, since the inner peripheral diameter of the mounting jig 10 is larger than the small diameter portion 66 of the stator holder 60, the mounting jig can move toward the distal end side (the large diameter portion 64 side) along the outer peripheral surface of the stator holder 60.
As shown in fig. 5 (B), the positioning portion 40 of the main body 16 is locked by abutting against the boundary portion between the large diameter portion 64 and the small diameter portion 66 of the stator holder 60, and is set in a positioning state in which further movement toward the distal end side is restricted. At this time, the distal end of the mounting portion 48 of the main body 16 is disposed substantially coplanar with the proximal end surface of the seal groove 68.
That is, the main body 16 is formed: the length from the positioning portion 40 thereof to the tip end of the mounting portion 48 is substantially equal to the distance from the boundary portion of the large diameter portion 64 and the small diameter portion 66 in the stator holder 60 to the base end surface of the seal groove 68.
In this mounting jig 10, in a state where the holder 14 is positioned in the axial direction (the direction of arrow B) on the outer peripheral side of the stator holder 60, as shown in fig. 5C, an operator (not shown) pushes the holder 14 toward the distal end side (the direction of arrow B), whereby the pusher 12 moves together with the holder 14 toward the distal end side (the direction of arrow B) by a predetermined distance against the elastic force of the spring 44.
At this time, since the positioning portion 40 is engaged with the large diameter portion 64 of the stator holder 60, the movement of the main body 16 to the distal end side is restricted so as not to move. When the pusher 12 moves toward the distal end side along the body 16, the seal ring 20 is pushed in the axial direction by the pushing portion 22 and moves toward the distal end side (direction of arrow B) along the attachment portion 48. The seal ring 20 is pushed upward and moved by gravity in a state of being in close contact with the flat portion 28 of the pusher 12 which is located below.
As shown in fig. 5 (C), the seal ring 20 moves to the tip end of the mounting portion 48 by the pressing action of the pressing portion 22, and the tip end of the mounting portion 48 is substantially flush with the flat portion 28 by the protrusion 32 coming into contact with the main body 16 to function as a stopper, and the seal ring 20 is reduced in diameter toward the inside in the radial direction by its own elasticity, and is housed and attached in the seal groove 68 of the stator holder 60 disposed on the inside in the radial direction with respect to the tip end of the mounting portion 48, as shown in fig. 5 (D). Thereby, the operation of mounting the seal ring 20 to the seal groove 68 of the stator holder 60 using the mounting jig 10 is ended.
As described above, in the present embodiment, the mounting jig 10 capable of mounting the seal ring 20 to the seal groove 68 of the cylindrical object such as the stator holder 60 is configured such that: the seal ring 20 is provided so as to abut against the tip of the pusher 12 over the entire circumference, the pusher 12 is provided so as to be movable in the axial direction with respect to the main body 16 provided on the inner circumferential side of the pusher 12, and the seal ring 20 is attached to the outer circumferential side of an attachment portion 48 formed on the tip of the main body 16.
Therefore, the mounting jig 10 to which the seal ring 20 is mounted is inserted through the outer peripheral side of the stator holder 60, the body 16 is locked at a position where the mounting portion 48 faces the seal groove 68 of the stator holder 60, and then the pusher 12 is moved toward the tip end side relative to the body 16, whereby the pusher 12 pushes the seal ring 20 in the axial direction and the seal ring 20 can be moved along the mounting portion 48.
Further, in the direction (radial direction of the seal ring 20) orthogonal to the moving direction (direction of arrow A, B) of the seal ring 20, a part of the seal ring 20 located on the inner peripheral side of the stator holder 60 side is pushed in the axial direction (direction of arrow B) by the flat portion 28 of the pusher 12. Therefore, by pressing the portion on the inner circumferential side as described above, the seal ring 20 can be moved while preventing the occurrence of twisting when the outer circumferential side of the seal ring 20 is pressed in the axial direction.
As a result, the pusher 12 pushes a portion of the seal ring 20 located on the stator holder 60 side (inner circumferential side) in the axial direction to move the seal ring 20 toward the distal end side, thereby reliably and efficiently mounting the seal ring 20 to the seal groove 68 of the stator holder 60 as an object while preventing occurrence of twisting.
Further, by being attached to the seal groove 68 while reliably preventing the distortion of the seal ring 20, the sealing performance of the seal ring 20 attached to the seal groove 68 can be ensured, and the attachment operation can be performed efficiently. In particular, it is more effective in the case where the seal ring 20 and the stator holder 60 have a large diameter. Further, even when the distance for moving the seal ring 20 is long, the structure can be light and simple.
The mounting jig 10 has a main body 16, and the main body 16 is disposed along the outer peripheral surface (the large diameter portion 64 and the small diameter portion 66) of the stator holder 60, and supports the pusher 12 slidably in the moving direction of the seal ring 20, thereby making it possible to easily and reliably move the seal ring 20 to a position facing the seal groove 68 on the outer peripheral side of the stator holder 60.
As a result, even when the outer peripheral surface of the stator holder 60 has a concave-convex shape having the annular groove 70 and the annular concave portion 72 other than the seal groove 68, the seal ring 20 can be reliably moved to and attached to the desired seal groove 68.
Further, the main body 16 is configured to: the pusher 12 is provided on the outer peripheral side thereof, and the seal ring 20 is attached to the outer peripheral side of the attachment portion 48 formed at the tip end thereof. Thus, by positioning the tip end of the mounting portion 48 with respect to the seal groove 68 of the stator holder 60, the seal ring 20 to which the mounting portion 48 is mounted can be positioned well with respect to the seal groove 68. Further, by providing the body 16 on the inner peripheral side of the pusher 12, the pusher 12 does not slide on the large diameter portion 64 and the small diameter portion 66 of the stator holder 60 when the pusher 12 is moved in the axial direction, and therefore, the outer peripheral surface of the stator holder 60 including the large diameter portion 64 can be favorably prevented from being worn.
Further, since the main body 16 has the positioning portion 40 that protrudes radially inward at the base end side thereof and is locked to the large diameter portion 64 of the stator holder 60, the tip end of the mounting portion 48 can be positioned at a position facing the seal groove 68 with high accuracy by reliably locking the main body 16 to the stator holder 60 in the axial direction.
Further, by positioning the mounting portion 48 of the main body 16 at a position facing the base end surface of the seal groove 68 in the moving direction of the seal ring 20, it is possible to avoid the seal ring 20 from being erroneously mounted on the annular groove 70 and the annular recess 72 which are provided on the outer peripheral surface of the stator holder 60 and which are in the insertion direction with respect to the seal groove 68, and thus it is possible to reliably and accurately mount the seal ring 20 to the desired seal groove 68.
As shown in fig. 5D, the pusher 12 and the main body 16 are coupled to each other via a spring 44 that biases in a direction (arrow a direction) opposite to the pushing direction of the seal ring 20, and after the seal ring 20 is attached, the pusher 12 can be moved relative to the main body 16 by the elastic force of the spring 44 and can be returned to a predetermined position (see fig. 5 a).
Therefore, when the mounting jig 10 is used to successively mount the seal rings 20 on a plurality of objects (stator holders 60), the pusher 12 and the main body 16 do not need to be manually returned to the initial positions by the operator, and the operation efficiency can be improved.
In the above embodiment, the description has been given of the case where the seal ring 20 is attached to the seal groove 68 of the stator holder 60 using the attachment jig 10, but the present invention is not limited to this, and an elastic ring such as the seal ring 20 may be attached to the annular groove 70 formed in the cylindrical object.
In addition, the elastic ring mounting jig 10 according to the present invention has the following structure: the pusher 12 is returned to the initial position by the spring 44, assuming that the operator manually operates the pusher, but the present configuration is effective also in the case where the attachment of the seal ring 20 is performed by automation, for example, and can be replaced with another power source instead of the spring 44.
The elastic ring attachment jig 10 according to the present invention is not limited to the above-described embodiment, and various configurations can be adopted without departing from the spirit of the present invention.
