When the combination of the technical solutions is contradictory or cannot be achieved, it should be considered that such a combination of technical solutions does not exist and is not within the scope of protection required by the present application.

[0039] According to the embodiments of the present application, a tooling for removing the inner tube of a jig is provided. The following will be combined with Figure 1 Specifically describe the structure and working principle of the tooling for removing the inner tube of a jig.

[0040] In an embodiment, Figure 1 FIG. shows a schematic diagram of a jig inner tube removal tool in a working state according to an embodiment of the present application. Among them, Figure 1 only the jig inner tube 400 is shown, specifically, the part of the jig inner tube 400 that protrudes above the outer tube of the jig, while the outer tube of the jig is omitted. Figure 2 FIG. shows a schematic plan view of a base member of a jig inner tube removal tool according to an embodiment of the present application. This plan view is a view of the base member observed along a horizontal direction perpendicular to the vertical direction. Figure 3 FIG. shows a schematic three-dimensional view of a connecting member of a jig inner tube removal tool according to an embodiment of the present application.

[0041] According to an embodiment of the present application, a jig inner tube removal tool is provided. The jig inner tube removal tool includes a base member 100, a connecting member 200, and a force applying member 300. In an embodiment, the base member 100 includes a first annular portion 110 and an extension portion 120 connected to each other. The first annular portion 110 is used to be sleeved outside the jig inner tube 400. The connecting member 200 includes a head portion 210 and a beam portion 220. The head portion 210 is used to connect with the jig inner tube 400, and the beam portion 220 is connected to the outside of the head portion 210. The force applying member 300 includes a rod portion 310. The first end of the rod portion 310 is detachably connected to the beam portion 220. The middle portion of the rod portion 310 abuts against the extension portion 120. The second end of the rod portion 310 can be pressed down, so that the middle portion of the rod portion 310 rotates around the position where it abuts against the extension portion 120 to lift the connecting member 200.

[0042] Thus, for the jig inner tube removal tool provided according to an embodiment of the present application, the first annular portion 110 is sleeved outside the jig inner tube 400 to realize the relative fixation of the jig inner tube removal tool with respect to the jig inner tube 400. Then, the connecting member 200 is connected to the jig inner tube 400 by using the head portion 210 of the connecting member 200. The first end of the rod portion 310 of the force applying member 300 is detachably connected to the connecting member 200, and the second end of the rod portion 310 is pressed down while the middle portion of the rod portion 310 abuts against the extension portion 120 of the base member 100. Thus, with the position where the middle portion of the rod portion 310 abuts against the extension portion 120 as a fulcrum, the first end of the rod portion 310 is lifted, and further the connecting member 200 and the jig inner tube 400 connected to the connecting member 200 are lifted.

[0043] Therefore, the jig inner tube removal tooling provided by the embodiments of the present application uses the rod portion 310 of the force application member 300, the extension portion 120 of the base member 100, and the beam portion 220 of the connection member 200 as a lever to lift the jig inner tube 400 out of the jig outer tube, avoiding the situation of damaging the jig inner tube 400 by using methods such as manual knocking in the prior art. Therefore, reusing the jig inner tube 400 hardly affects the use accuracy in subsequent assembly segments.

[0044] That is to say, according to the jig inner tube removal tooling provided by the embodiments of the present application, using the lever principle, the jig inner tube 400 can be lifted from bottom to top, so that the jig inner tube 400 can be effectively separated from the jig outer tube.

[0045] According to the jig inner tube removal tooling provided by the embodiments of the present application, the extension portion 120 may further include a second annular portion 121 and an extension section. The first annular portion 110 and the second annular portion 121 may be arranged opposite to each other. The extension section may connect the first annular portion 110 and the second annular portion 121. The first annular portion 110 and the second annular portion 121 may be coaxially arranged.

[0046] In an embodiment, the second annular portion 121 may be located above the first annular portion 110 during the actual operation of the jig inner tube removal tooling. Therefore, the beam portion 220 of the connection member 200 may pass through the second annular portion 121 and lean against the inner side of the second annular portion 121. In this way, when lifting the jig inner tube 400, the stability of the connection member 200 can be improved, and the situation of loosening between the connection member 200 and the force application member 300 caused by the force application member 300 applying force to the connection member 200 can be avoided.

[0047] As an example, in an embodiment, both the first annular portion 110 and the second annular portion 121 may be, for example, ring-shaped structures. In addition, in an embodiment, the first annular portion 110 and the second annular portion 121 may be coaxially arranged, and both may have a certain height in the axial direction, so that the sleeving of the first annular portion 110 on the jig inner tube 400 is more stable, and the supporting area of the second annular portion 121 for the connection member 200 is larger and the supporting effect is more reliable.

[0048] According to the fixture for removing the inner pipe of the tire rack provided by the embodiment of the present application, the extension section may include a first extension part 122 and at least one second extension part 123. In an embodiment, the first extension part 122 may include a first end and a second end opposite to each other. The first end of the first extension part 122 may be connected to the first annular part 110, and the second end of the first extension part 120 may be connected to the second annular part 121. In an embodiment, by way of example, the first extension part 122 may be a strip structure, and the second extension part 123 may also be a strip structure.

[0049] In an embodiment, the second extension part 123 may be connected to the first annular part 110, and the length of the second extension part 123 may be less than that of the first extension part 122 to form an end surface opposite to the second annular part 121, and the end surface is for the middle part of the force-applying member 300 to abut against.

[0050] In an embodiment, the length of the second extension part 123 is less than that of the first extension part 122, and the first extension part 122 connects the first annular part 110 and the second annular part 121, which means that the above-mentioned end surface of the second extension part 123 is spaced apart from the second annular part 121 located above. Thus, the aforementioned end surface of the second extension part 123 can also be used to abut against the middle part of the rod part 310 of the force-applying member 300 to form a fulcrum of the lever.

[0051] In an embodiment, the advantage of arranging the second extension part 123 as above is that when the position of part of the inner pipe 400 of the tire rack is relatively low, even if the connecting member 200 is connected to the inner pipe 400 of the tire rack, the beam part 220 of the connecting member 200 may be too close to the vertical direction due to the too low height of the inner pipe 400 of the tire rack, which is not conducive to the formation of the lever.

[0052] In an embodiment, compared with the end surface of the second extension part 123 which is lower than the first annular part 110, the above-mentioned end surface of the second extension part 123 is used when the height of the inner pipe 400 of the tire rack is relatively low, so as to raise the height of the inner pipe 400 of the tire rack in a more labor-saving manner.

[0053] According to the fixture for removing the inner pipe of the tire rack provided by the embodiment of the present application, the number of the second extension parts 123 may be multiple, and each second extension part 123 may be connected to the first extension part 122, and the lengths of the second extension parts 123 included in the extension section are different from each other.

[0054] In this way, according to the fixture for removing the inner pipe of the tire rack provided by the embodiment of the present application, the second extension parts 123 with different heights are provided, so as to ensure that the process of continuously lifting the inner pipe 400 of the tire rack can continue.

[0055] In an embodiment, by way of example, the number of the second extension portions 123 may be two. The two second extension portions 123 may be connected to both sides of the first extension portion 122, and the two second extension portions 123 may have different lengths.

[0056] As an example, in an embodiment, in the fixture for removing the inner pipe of the building bracket, the first extension portion 122, the second extension portion 123, the first annular portion 110, and the second annular portion 121 are integrally formed, so that the base member 100 can provide better stability.

[0057] According to the fixture for removing the inner pipe of the building bracket provided by the embodiment of the present application, the head 210 includes: a first wall portion 211 and a second wall portion 212 that are oppositely arranged. The first wall portion 211 has a first through hole, and the second wall portion 212 has a second through hole correspondingly arranged with the first through hole. In an embodiment, a pin member is used to pass through the first through hole and the second through hole, and the pin member is further used to penetrate through the inner pipe 400 of the building bracket to connect the head 210 and the inner pipe 400 of the building bracket.

[0058] According to the fixture for removing the inner pipe of the building bracket provided by the embodiment of the present application, the beam portion 220 includes a plurality of force application through holes 221 that are spaced apart along the extension direction of the beam portion 220, and the through holes are used for the rod portion 310 to pass through.

[0059] According to the fixture for removing the inner pipe of the building bracket provided by the embodiment of the present application, the beam portion 220 may include a plurality of ear plates that are spaced apart along the extension direction of the beam portion 220, and the ear plates have first connection holes penetrating through the ear plates. In an embodiment, the rod portion 310 may have second connection holes penetrating through the ends of the rod portion 310, and the fixture for removing the inner pipe of the building bracket further includes a connecting member such as a pin, and the connecting member passes through the first connection hole and the second connection hole to connect the rod portion 310 and the beam portion 220.

[0060] In other examples, the beam portion 220 may include a plurality of baffles that are spaced apart along the extension direction of the beam portion 220. The baffles and a part of the beam portion 220 are oppositely arranged to jointly form a groove portion with the part of the beam portion 220. The rod portion 310 has a hook portion, and the hook portion can be used to insert into the groove portion to connect the rod portion 310 and the beam portion 220.

[0061] The above are only the preferred embodiments of the present application, and do not limit the protection scope of the present application accordingly.
