Problems to be solved by the utility model
Such a cap seal has a configuration in which the diameter of the engagement portion 103 of the cylindrical portion 102 is larger than the diameter of the engagement recess 202 of the shaft hole 201, and the engagement portion 103 of the cylindrical portion 102 has an interference with respect to the engagement recess 202 of the shaft hole 201. With respect to the cap seal having the engagement portion in which such interference is set, a check is made to confirm whether the produced cap seal can exhibit a desired anti-slip function. The inspection is performed using a jig.
Such an inspection jig for inspecting the interference of the cap seal is formed with a hole corresponding to the shaft hole 201, and after the cap seal 100 is mounted in the hole of the inspection jig, the diameter of the engagement portion 103 of the cylindrical portion 102 of the cap seal 100 detached from the inspection jig is measured to perform inspection. When the measured diameter of the engaging portion 103 of the tubular portion 102 is larger than the diameter of the engaging recess 202 of the shaft hole 201, it is determined that the cap seal 100 has a desired interference, and when the measured diameter of the end portion 102a of the tubular portion 102 is equal to or smaller than the diameter of the engaging recess 202 of the shaft hole 201, it is determined that the cap seal 100 does not have a desired interference.
In the inspection of the interference, the seal portion 102 cannot be damaged when the cap seal 100 is detached from the inspection jig. In order to detach the cap seal 100 from the inspection jig, the conventional inspection jig needs to be cut off to break the inspection jig and remove the anti-drop function. Therefore, the conventional inspection jig is troublesome in inspection. In addition, the conventional inspection jigs cannot be reused. In addition, in order to perform an accurate inspection, the number of inspection jigs is required to be increased, and in the conventional inspection jigs, the number of inspection jigs required to perform an accurate inspection is increased. As described above, the conventional inspection jigs for cap seals are expensive and environmentally unfriendly.

Detailed Description
Hereinafter, embodiments of the present utility model will be described with reference to the drawings.
The inspection jig for a cap seal according to the present utility model is used for inspecting whether or not the cap seal is manufactured in a desired shape, size, or the like. The cap seal is a member for closing the hole. The hole for attaching the cover seal is, for example, a hole provided in a shaft hole of a gear or the like in a machine such as a transmission or a differential gear of an automobile. Fig. 4 is a view showing an example of a lid seal using the lid seal inspection jig according to the present utility model, and is a cross-sectional view of an example of the lid seal 100. Fig. 5 is a sectional view showing the mounted state of the cap seal 100 shown in fig. 4.
As shown in fig. 4, the cap seal 100 includes a metal body 101 and a seal portion 110 provided at an end of the body 101. The main body 101 has: the cylindrical portion 102 is a cylindrical portion extending along the axis x 1; and a bottom 104 connected to one end (end 102 a) of the tubular portion 102 in the direction of the axis x 1. The bottom 104 extends along a plane orthogonal to the axis x1, closing the opening of the end 102a side of the tubular portion 102. The cylindrical portion 102 has, for example, a plurality of cylindrical portions, and adjacent cylindrical portions are stepped and juxtaposed in the direction of the axis x 1. Specifically, for example, the tube 102 has an engagement portion 103 and a cylindrical portion 105 extending along the axis x 1. The diameter of the engaging portion 103 is larger than the diameter of the cylindrical portion 105, and the engaging portion 103 and the cylindrical portion 105 are connected via the tapered portion 106.
The engagement portion 103 is formed at the other end of the cylindrical portion 102. The engagement portion 103 is a portion that engages with the engagement recess 202 of the shaft hole 201. The outer peripheral surface 103a of the engagement portion 103 is, for example, a cylindrical surface or a substantially cylindrical surface having the axis x1 as a central axis or a substantially central axis. The diameter D1 of the outer peripheral surface 103a of the engagement portion 103 is larger than the diameter D1 of the inner peripheral surface 202a of the engagement recess 202 of the shaft hole 201 (see fig. 5), and the engagement portion 103 is formed to have an interference delta of a predetermined size with respect to the engagement recess 202. The tapered portion 106 has a shape that smoothly connects the engagement portion 103 and the cylindrical portion 104. The tapered portion 106 expands in diameter from the cylindrical portion 105 side toward the engaging portion 103 side, for example.
As shown in fig. 4, the sealing portion 110 is expanded so as to cover the bottom 104 of the cylindrical portion 102 and the cylindrical portion 105. The outer peripheral surface 110a of the seal portion 110 contacts the seal surface portion 203 of the shaft hole 201, and closes the opening of the shaft hole 201.
The member 200 to which the cover seal 100 is attached is, for example, a power transmission member of a transmission or a differential side gear of a differential gear. As shown in fig. 5, the cap seal 100 is attached to a shaft hole 201 formed in the member 200, and seals the shaft hole 201 by closing the shaft hole 201. Specifically, as shown in fig. 5, the seal portion 110 of the cap seal 100 is accommodated in the seal surface portion 203 of the shaft hole 201, and the seal surface portion 203 is closed to seal the shaft hole 201. The cap seal 100 is mounted to the shaft hole 201 through an access opening 204, the access opening 204 being one opening of the shaft hole 201.
As shown in fig. 5, the engagement portion 103 of the cap seal 100 is received in the engagement recess 202 of the shaft hole 201, and is engaged with the engagement recess 202. Specifically, the engagement portion 103 deforms in accordance with the interference δ, and comes into contact with the inner peripheral surface 202a of the engagement recess 202 with a reaction force directed radially outward. The end portion (end portion 103 b) of the engagement portion 103 is in contact with the annular surface 202b of the engagement recess 202 in the direction of the axis x 1. Therefore, the engagement portion 103 and the engagement recess 202 are engaged with each other by the snap fit, thereby exhibiting a strong anti-disengagement function. The annular surface 202b is a portion of the engagement recess 202 extending annularly along a surface orthogonal to the axis x1 on the side of the entrance opening 204.
Fig. 1 is a sectional view of a cap seal inspection jig 1 according to an embodiment of the present utility model at a section along an axis x, and fig. 2 is an exploded perspective view of the cap seal inspection jig 1. As described above, the cap seal inspection jig (hereinafter, simply referred to as "inspection jig") 1 is used to inspect whether the manufactured cap seal 100 has a desired shape and size (see fig. 4), and whether the cap seal 100 is mounted in a desired shape in the shaft hole 201 of the component 200. The inspection jig 1 is particularly used for inspecting whether or not the engagement portion 103 of the produced cap seal 100 is received in the engagement recess 202 of the shaft hole 201, and forming a desired snap engagement with the engagement recess 202.
As shown in fig. 1, the inspection jig 1 includes a main body 10 and a cover 20 detachably fixed to the main body 10. A cap seal accommodating recess 30 is provided between the main body 10 and the cap 20 fixed to the main body 10, and the cap seal accommodating recess 30 is a recess capable of accommodating the cap seal 100 and corresponds to the shaft hole 201. An engagement recess 31 corresponding to the engagement recess 202 provided in the shaft hole 201 of the member 200 is formed in the lid seal housing recess 30. The engagement recess 31 has the same shape and size as the engagement recess 202 provided in the shaft hole 201, and is an annular recess that accommodates the engagement portion 103 of the lid seal 100 and engages with the engagement portion 103. At least a portion of the engaging recess 31 on the side of the entrance opening 33 (lower side in fig. 1) is formed in the cover 20. The access opening 33 is an opening of the cover seal receiving recess 30 corresponding to the access opening 204 of the shaft hole 201. Further, as described above, the access opening 204 is an opening of the shaft hole 201 through which the lid seal 100 passes when the lid seal 100 is mounted to the shaft hole 201 of the member 200. Hereinafter, the inspection jig 1 will be specifically described.
As shown in fig. 1 and 2, the cap seal housing recess 30 extends along the axis x of the inspection jig 1 and has the same shape as the shaft hole 201 of the member 200. That is, the cap seal housing recess 30 has the engagement recess 31 corresponding to the engagement recess 202 of the shaft hole 201 as described above, and has the seal surface portion 32 juxtaposed with the engagement recess 31 in the axis x direction and corresponding to the seal surface portion 203 of the shaft hole 201. The seal surface portion 32 has the same shape and size as the seal surface portion 203, and accommodates the seal portion 110 of the cap seal 100 on the inner peripheral side and contacts the seal portion 110 from the outer peripheral side.
Specifically, the engagement recess 31 includes: the end surfaces 31b and 31c are surfaces facing each other in the direction of the axis x and annular about the axis x; and a bottom surface 31a that is a cylindrical surface extending along the axis x and extends between an end on the outer peripheral side of the end surface 31b and an end on the outer peripheral side of the end surface 31 c. The end face 31b is located on the sealing surface 32 side. The end surface 31b is formed in a shape that does not interfere with the tapered portion 106 of the lid seal 100 when the engagement portion 103 of the lid seal 100 is accommodated in the engagement recess 31 and the engagement portion 103 is engaged with the engagement recess 31, and is formed as a tapered surface that expands in diameter from the sealing surface portion 32 side toward the bottom surface 31a side, for example, as shown in fig. 1. The end surface 31c is, for example, a torus or a substantially torus centered or substantially centered on the axis x, which extends parallel or substantially parallel to a surface orthogonal to the axis x. The bottom surface 31a is, for example, a cylindrical surface or a substantially cylindrical surface having the axis x as a central axis or a substantially central axis.
The seal surface 32 is, for example, a cylindrical surface or a substantially cylindrical surface having the axis x as a central axis or a substantially central axis. As shown in fig. 1, the seal surface 32 is connected to the inner peripheral end of the annular surface 31b of the engagement recess 31, similarly to the seal surface 203 of the shaft hole 201 of the member 200.
As described above, the cap seal housing recess 30 penetrates the body 10 and the cap 20 in the axis x direction, similarly to the shaft hole 201 of the member 200. The lid seal accommodating recess 30 is formed in the main body 10 and the lid body 20 such that a portion thereof corresponding to a portion of the shaft hole 201 on the side of the entrance opening 204 is located in the lid body 20 and the other portion thereof is located in the main body 10. In the present embodiment, as shown in fig. 1, a portion of the lid seal accommodating recess 30 from the bottom surface 31a of the engaging recess 31 toward the access opening 33 is formed in the lid body 20, and the other portion of the lid seal accommodating recess 30 is formed in the main body 10. In addition, the diameter of the portion of the cap seal housing concave portion 30 other than the seal face portion 32 is larger than the diameter of the seal face portion 32. In the inspection jig 1, a side in a direction from the main body 10 side toward the lid 20 side in the axis x direction is an entrance opening 33 side, and a lower side in fig. 1 is an entrance opening 33 side.
Specifically, for example, as shown in fig. 1 and 2, the main body 10 is a circular or substantially circular plate-like member, and a lid accommodating recess 11 is formed, and the lid accommodating recess 11 is a recess capable of accommodating the lid 20. The cover accommodating recess 11 is formed in the inspection jig 1 on a surface (mounting side surface 10 a) on the side of the access opening 33, and is recessed inward (upward in fig. 1) from the mounting side surface 10 a. The cover accommodating recess 11 has the following shape: when the lid 20 is accommodated in the lid accommodating recess 11, the axis x of the portion of the lid seal accommodating recess 30 formed in the lid 20 coincides with or substantially coincides with the axis x of the portion of the lid seal accommodating recess 30 formed in the main body 10. For example, the contour of the lid housing recess 11 centered on the axis x as viewed in the axis x direction coincides with or substantially coincides with the contour of the lid 20 centered on the axis x as viewed in the axis x direction. As shown in fig. 1, a portion opposite to the side of the entrance opening 33 (upper side in fig. 1) from the end surface 31b of the engagement recess 31 of the lid seal accommodating recess 30 is formed in the main body 10. That is, the body 10 is formed with an end face 31b of the engagement concave portion 31 and the seal face 32 along the axis x.
Specifically, as shown in fig. 1 and 2, for example, the cover 20 is a circular or substantially circular plate-like member. As shown in fig. 1, the lid body 20 is formed with a portion closer to the entrance opening 33 side (lower side in fig. 1) from the bottom surface 31a of the engagement recess 31 of the lid seal accommodating recess 30. That is, the lid 20 is formed with the bottom surface 31a and the end surface 31c of the engagement recess 31 and the entrance opening 33 along the axis x, and the entrance opening 33 is a portion corresponding to the entrance opening 204 of the shaft hole 201. The inlet opening 33 forms an opening in the cover 20, and in addition, has the same diameter as the inlet opening 204 of the shaft hole 201, and has the same shape as the inlet opening 204. The inlet opening 33 has the same diameter as the inlet opening 204 of the shaft hole 201, but the shape of the cross section along the axis x may be a different shape from the inlet opening 204.
In addition, the inspection jig 1 includes a fixing mechanism 40 for detachably fixing the cover 20 to the main body 10. The fixing mechanism 40 is, for example, at least one screw 41 and at least one screw hole 42 corresponding to the at least one screw 41. A screw hole 42 is formed in one of the body 10 and the cover 20, and a through hole 43 through which the screw 41 passes is formed in the other of the body 10 and the cover 20. As shown in fig. 1, the inspection jig 1 of the present embodiment is provided with a plurality of screws 41 and a number of screw holes 42 corresponding to the number of screws 41, and the plurality of screw holes 42 are provided in the cover 20. The plurality of through holes 43 are provided in the main body 10. The screw hole 42 and the through hole 43 extend along the axis x.
The inspection jig 1 has the above-described structure, and the cover 20 is accommodated in the cover accommodating portion 11 of the main body 10, and the screws 41 are fastened to the screw holes 42, whereby the cover 20 is fixed to the main body 10. As described above, the main body 10 and the lid 20 accommodated in the lid accommodating portion 11 form the lid seal accommodating recess 30 similar to the shaft hole 201. On the other hand, the screws 41 are removed from the screw holes 42, and the cover 20 is removed from the cover housing portion 11 of the main body 10, whereby the main body 10 is separated from the cover 20.
Next, an inspection method of the cap seal 100 using the inspection jig 1 having the above-described structure will be described.
Fig. 3 is a sectional view along the axis x of the inspection jig 1 with the cap seal 100 mounted thereto. The inspection jig 1 is used to inspect whether or not the engagement portion 103 of the manufactured cap seal 100 has a desired interference δ with respect to the engagement recess 31. To perform the interference check, first, the lid 20 is stored in the lid storage portion 11 of the main body 10, and the lid 20 is fixed to the main body 10 by the fixing mechanism 40. Then, the cap seal 100 is mounted on the inspection jig 1 in a state where the cap 20 is fixed to the main body 10. Specifically, the lid seal 100 is pressed in the direction of the arrow in fig. 3, and the lid seal 100 is inserted into the lid seal accommodating recess 30 from the access opening 33, and the lid seal 100 is mounted to the lid seal accommodating recess 30.
As shown in fig. 3, when the cap seal 100 is mounted in the cap seal housing recess 30 of the inspection jig 1, the seal portion 110 of the cap seal 100 is housed in the seal surface portion 32 of the cap seal housing recess 30, and the engagement portion 103 of the cap seal 100 is housed in the engagement recess 31 of the cap seal housing recess 30. When the lid seal 100 is manufactured in a desired shape and size, the outer peripheral surface 110a of the seal portion 110 of the lid seal 100 contacts the seal surface portion 32 of the lid seal accommodating recess 30. Further, the outer peripheral surface 103a of the engagement portion 103 of the cap seal 100 contacts the bottom surface 31a of the engagement recess 31, and the engagement portion 103 or the cylindrical portion 102 elastically deforms toward the inner peripheral side in accordance with the interference δ, and a reaction force toward the outer peripheral side acts on the bottom surface 31a.
In the interference check, next, the cap seal 100 is detached from the check jig 1, and the diameter d1 of the outer peripheral surface 103a of the engagement portion 103 of the cap seal 100 is measured. To remove the cap seal 100, first, the screws 41 are removed from the screw holes 42, the cap 20 is removed from the cap housing recess 11, and the cap 20 is separated from the main body 10. When the lid 20 is detached from the main body 10, the end surface 31c that functions as the locking recess 31 is removed from the lid seal accommodating recess 30. Therefore, the cover seal 100 can be detached from the inspection jig 1 (the main body 10) without further deformation of the cylindrical portion 102 due to the detachment of the cover 20 from the main body 10 and without damage to the inspection jig 1 by cutting or the like, due to the release preventing function of the engagement recess 31.
In the interference check, next, the diameter d1 of the outer peripheral surface 103a of the engagement portion 103 of the cap seal 100 detached from the check jig 1 is measured. When the diameter D1 of the outer peripheral surface 103a of the engagement portion 103 is larger than the diameter D1 of the inner peripheral surface 202a of the engagement recess 202 of the shaft hole 201 as a result of measurement of the diameter D1 of the outer peripheral surface 103a (D1 > D1), it is determined that the engagement portion 103 of the cap seal 100 has a desired interference δ. On the other hand, when the measured diameter D1 of the outer peripheral surface 103a of the engagement portion 103 is equal to or smaller than the diameter D1 of the inner peripheral surface 202a of the engagement recess 202 of the shaft hole 201 (D1. Ltoreq.d1), it is determined that the engagement portion 103 of the cap seal 100 does not have the desired interference δ.
As described above, the inspection jig 1 can remove the cap seal 100 from the inspection jig 1 only by removing the cap body 20 from the main body 10. Further, the cover 20 can be easily removed from the main body 10 by removing the screw 41. In this way, the inspection of the cap seal 100 using the inspection jig 1 is not too cumbersome.
The inspection jig 1 for inspecting the cap seal 100 can be used for inspecting a new cap seal 100 by accommodating the cap 20 again in the cap accommodating portion 11 of the main body 10, fastening the screws 41 to the screw holes 42, and fixing the cap 20 to the main body 10. In this way, the inspection jig 1 can be reused a plurality of times for inspection of the cap seal 100. Further, since the lid 20 can be detached from the main body 10 as described above, the main body 10 and the lid 20 do not need to be damaged in order to detach the lid seal 100, and the inspection jig 1 can be reused for inspection of the lid seal 100. Further, since the lid 20 can be detached from the main body 10 without damaging the main body 10 and the lid 20, the lid seal 100 is not damaged when the lid 20 is detached from the main body 10.
Further, since the diameter of the portion of the lid seal housing concave portion 30 other than the seal surface portion 32 is larger than the diameter of the seal surface portion 32, damage to the seal portion 110 of the lid seal 100 can be suppressed when the lid seal 100 is mounted to the inspection jig 1. In the main body 10, the diameter of the portion of the lid seal housing concave portion 30 other than the seal surface portion 32 is also larger than the diameter of the seal surface portion 32, so that damage to the seal portion 110 of the lid seal 100 can be suppressed when the lid seal 100 is detached from the inspection jig 1.
As described above, according to the inspection jig 1 according to the embodiment of the present utility model, the trouble of inspection can be reduced. Further, since the inspection jig 1 can be reused without being damaged, even if one inspection jig 1 is repeatedly used, the inspection can be repeated accurately, and the cost for the inspection can be reduced, and the inspection can be made environment-friendly.
While the embodiments of the present utility model have been described above, the present utility model is not limited to the inspection jig 1 according to the embodiments of the present utility model, but includes all aspects including the concept of the present utility model and the claims. In order to achieve at least a part of the above-described problems and effects, the respective structures may be selectively combined as appropriate. For example, the shape, material, arrangement, size, and the like of each structure in the above-described embodiments can be appropriately changed according to a specific use mode of the present utility model.
For example, the inspection object of the inspection jig of the present utility model is not limited to the cap seal 100. The cap seal housing concave portion includes a shape corresponding to various types of cap seals, and the inspection jig of the present utility model can be used for various cap seals as inspection targets.
For example, the body 10 of the inspection jig 1 may not have the cover accommodating recess 11. The body 10 or the cover 20 may have other structures capable of positioning the cover 20 at a desired position with respect to the body 10. For example, the cap seal housing concave portion 30 of the inspection jig 1 may not have the seal surface portion 32.
For example, the lid seal housing recess 30 may have a shape corresponding to a part of the shaft hole 201 to which the lid seal 100 is attached. Therefore, for example, the lid seal accommodating recess 30 may be a recess having a bottom, not a through hole, but a recess having a bottom formed by spot facing. The lid seal accommodating recess 30 may be a through hole formed by spot facing, for example.
