DETAILED DESCRIPTION

[0035] The technical solution of the present invention is further described below with reference to embodiments and in conjunction with the accompanying drawings.

[0036] like Figures 1-8 As shown, an inner hole packaging device is used to package the workpiece 1. Figure 1 As shown, the workpiece 1 is the inner hub of the clutch. The workpiece 1 includes a boss 11 located at the top and a boss 2 12 located at the bottom. The boss 1 11 and the boss 2 12 are both frustum structures. The workpiece 1 is provided with a through hole 13, which passes through the workpiece 1 from top to bottom.

[0037] like Figure 1 、 Figure 2 As shown, the inner hole packaging device includes an insert ring 2, which is made of plastic. The insert ring 2 includes a cover plate and an extension ring 21 located below the cover plate. The extension ring 21 is inserted into the through hole 13 from the top of the through hole 13. The outer peripheral wall of the extension ring 21 is gap-matched with the inner peripheral wall of the through hole 13. The lower end face of the cover plate is fitted with the upper end face of the boss 11. The lower end face of the cover plate covers the entire upper end face of the boss 11, and the outer diameter of the lower end face of the cover plate is slightly larger than the upper end face of the boss 11, so that the cover plate can better protect the upper end face of the boss 11 from being bumped.

[0038] like Figure 1 As shown, a connecting ring 214 is provided at the bottom of the extension ring 21 , and the connecting ring 214 extends downward along the bottom of the extension ring 21 to form a ring structure. The outer diameter of the connecting ring 214 is smaller than the extension ring 21 , and the outer wall of the connecting ring 214 is provided with threads.

[0039] like Figure 2 As shown, the outer wall of the extension ring 21 is provided with a groove 211, which is a spiral groove. The groove 211 extends spirally along the outer wall of the extension ring 21, and the groove 211 extends from the bottom of the cover plate to the upper end of the connecting ring 214.

[0040] Combine Figure 2 、 Figure 3 、 Figure 4 The outer wall of the extension ring 21 is further provided with a second groove 212. The length direction of the second groove 212 extends along the axial direction of the extension ring 21. There are multiple second grooves 212 arranged along the circumference of the extension ring 21. The arrangement of the second groove 212 forms a tooth-like structure on the outer wall of the extension ring 21. The second groove 212 is connected with the first groove 211 along the axial direction of the extension ring 21. The width of the second groove 212 is relatively small. When lubricating oil is passed into the first groove 211, the second groove 212 can serve as an auxiliary circulation channel. The second groove 212 can also play the role of oil storage, thereby better protecting the inner wall surface of the through hole 13.

[0041] like Figure 2 As shown, a hole 213 is provided on the upper portion of the extension ring 21. The hole 213 passes through the inner side of the inner wall of the extension ring 21. The outer side of the hole 213 is connected to the groove 211. The hole 213 is gradually inclined inwardly along the radial direction of the extension ring 21 to facilitate the lubricating oil to enter the groove 211 from the hole 213 when oil is passed through, and to prevent the oil in the groove 211 from flowing back out of the hole 213.

[0042] like Figure 1 As shown, insert ring 1 2 is installed with insert ring 2 4, which is made of plastic. Insert ring 2 4 includes an extension column 42, which is inserted into the extension ring 21 from the bottom of insert ring 1 2. The outer peripheral wall of the extension column 42 is in contact with the inner peripheral wall of the extension ring 21. After insertion, the extension column 42 can move up and down and rotate along the inner peripheral wall of the extension ring 21.

[0043] like Figure 1 As shown, the second insert ring 4 also includes a base 41 located below the extension column 42. The base 41 is provided with an end cap 3 on the outside. The end cap 3 is made of plastic, and the inner circumference of the end cap 3 is in contact with the outer circumference of the base 41. The end cap 3 is provided with a protrusion on the inside, and the base 41 is provided with a groove on the outside. The protrusion of the end cap 3 is inserted into the groove of the base 41, so that the rotation of the end cap 3 can drive the rotation of the base 41.

[0044] The end cover 3 includes an inner ring 31 located at the bottom. The inner ring 31 extends radially inward along the inner wall of the end cover 3 to form an annular structure. The upper end of the inner ring 31 abuts against the lower end of the base 41. The inner ring 31 forms a supporting state for the base 41 to prevent the base 41 from sliding out downward.

[0045] The outer wall of the connecting ring 214 can be threadedly connected to the end cover 3, and after the connection, the base 41 and the connecting ring 214 fit together in the upper and lower parts.

[0046] like Figure 2 As shown, a slot 421 is provided on the outer side of the extension column 42. The slot 421 extends inwardly along the outer wall of the extension column 42. Figure 6 As shown, the latching slot 421 is provided on one side of the extension column 42 .

[0047] like Figure 2 As shown, the insert ring 2 is provided with a protruding block 22, which protrudes radially inward along the inner wall of the insert ring 2. The protruding block 22 is located on one side of the hole 213, and the inner side of the hole 213 passes through the protruding block 22.

[0048] like Figure 2 As shown, the extension column 42 includes an end portion 423 located at the top. The end portion 423 is a circular inclined surface, and the end portion 423 gradually inclines downward along a side close to the locking slot 421 .

[0049] like Figure 2 As shown, when the extension column 42 is gradually inserted into the extension ring 21, the protrusion block 22 is inserted into the slot 421 by rotating the extension column 42, so that the circumferential position of the extension column 42 and the extension ring 21 is fixed. At this time, the position of the end 423 can be lower than the hole 1 213. After the lubricating oil is passed above the end 423, the lubricating oil can flow into the hole 1 213 along the end 423 and flow downward in a spiral along the groove 1 211. Part of the lubricating oil will also flow vertically downward along the groove 212, so that the inner wall of the through hole 13 forms an oiling effect.

[0050] like Figure 2 As shown, the extension column 42 includes an annular groove 422 located below the locking groove 421. The annular groove 422 is recessed radially inward along the outer wall of the extension column 42. The inner side of the protruding block 22 is an arc surface, and the arc surface matches the inner wall surface of the annular groove 422. Figure 5 As shown, the annular groove 422 is an annular groove. After the oiling process of the first hole 213 is completed, the extension column 42 continues to be inserted into the extension ring 21. At this time, the protrusion 22 is located in the annular groove 422, and the rotation limit of the extension column 42 is released. The extension column 42 can rotate along the inner wall of the extension ring 21. By rotating the end cover 3 to rotate the extension column 42, the outer wall of the extension column 42 and the inner wall of the extension ring 21 rub against each other, so that every position on the inner wall of the through hole 13 is covered with lubricating oil. The lubricating oil retained in the first groove 211 and the second groove 212 also forms a lubricating effect on the inner wall of the through hole 13.

[0051] like Figure 8 As shown, the extension column 42 is inserted upward to the limit position. At this time, the slot 421 is located above the protruding block 22, the protruding block 22 is located in the annular groove 422, and the inner side of the protruding block 22 is in contact with the inner wall of the annular groove 422, so that the inner side of the hole 213 is closed. Figure 7 、 Figure 8 During the process of inserting the extension column 42 upward to the limit position, after the protruding block 22 enters the annular groove 422, the end cover 3 is rotated and the connecting ring 214 is screwed in, so that the insert ring 1 2, the end cover 3, and the insert ring 2 4 are connected to each other and the workpiece 1 is pressed up and down.

[0052] like Figure 1 As shown, the bottom of the base 41 is provided with a groove 411, as shown in FIG. Figure 8 As shown, since the top of the extension column 42 extends out of the upper end of the insert ring 2, when stacked up and down, the top of the extension column 42 can penetrate into the groove 411 of another inner hole packaging device located above it, so as to facilitate storage and make the placement of the upper and lower adjacent inner hole packaging devices more stable and not easy to shake during transportation.

[0053] The packaging method of the above-mentioned inner hole packaging device is:

[0054] S1 installation ring 2:

[0055] like Figure 1 As shown, the extension ring 21 is inserted into the through hole 13, the outer peripheral wall of the extension ring 21 is in contact with the inner peripheral wall of the through hole 13, the groove 1 211 and the groove 2 212 are both connected to the inner wall of the through hole 13, and the lower end surface of the cover plate of the insert ring 1 2 is in contact with the upper end surface of the boss 11.

[0056] S2 installs end cover 3 and insert ring 2 4:

[0057] ① Such as Figure 1 As shown, the end cap 3 is inserted into the base 41 from the bottom of the base 41, and the protrusion of the end cap 3 is inserted into the groove of the base 41. The end cap 3 pushes the insert ring 24 so that the extension column 42 is inserted into the extension ring 21. The inner circumference of the extension ring 21 fits with the outer circumference of the extension column 42. By rotating the end cap 3 to rotate the extension column 42 and cooperate with the movement of the extension column 42, the protrusion block 22 is inserted into the card slot 421. At this time, Figure 2 As shown, the end portion 423 is tilted downwardly and points toward the hole 1 213 .

[0058] ② If Figure 2 As shown, by adjusting the upper and lower positions of the extension column 42, the height position of the end portion 423 is made lower than the height of the hole 1 213, and lubricating oil is poured above the end portion 423. The lubricating oil flows along the end portion 423 into the hole 1 213 and into the groove 1 211. The lubricating oil spirally flows downward along the groove 1 211 and lubricates and protects the inner wall of the through hole 13. At the same time, the lubricating oil also flows downward along the groove 212.

[0059] ③ Such as Figure 1 、 Figure 2 As shown, by rotating the end cover 3 to allow the extension column 42 to drive the insert ring 2 to rotate, the insert ring 2 rotates on the inner wall of the through hole 13, and then the lubricating oil in the groove 1 211 and the groove 2 212 covers the inner wall of the through hole 13 more evenly.

[0060] S3 fixed insert ring 2, end cover 3:

[0061] like Figure 7 、 Figure 8 As shown, push end cap 3 upward, causing extension post 42 to move upward until it extends beyond the top of insert ring 1 2. At this point, protrusion 22 is located below slot 421 and completely within annular groove 422. The inner wall of annular groove 422 abuts against the inner wall of protrusion 22, sealing the inner side of hole 1 213. End cap 3 is screwed into connecting ring 214.

[0062] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention.
