Description

Technical Field

[0001] This utility model relates to the field of tire manufacturing technology, and in particular to a quick-change device for tire rear inflation chuck. Background Technology

[0002] The rear inflation chuck is an essential tool in the tire production process. Its function is to inflate and shape the tire after the tire vulcanization is completed, by having a robotic arm remove the tire from the vulcanizing machine and place it on the rear inflation device to improve the tire's stability.

[0003] When producing tires of different specifications, it is necessary to replace the rear inflator chucks of different sizes. The existing method of fixing the chuck to the rim bracket is to use multiple bolts (usually 8) arranged in a circumferential pattern to fix the chuck to the rim bracket. When replacing it, each bolt must be completely unscrewed in turn, and each bolt must be tightened again after replacing the chuck. Therefore, this replacement method is not only extremely inefficient, which seriously affects the tire inflation efficiency, but also easily leads to wear of the rear inflator chuck and reduces its service life. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model discloses a quick-change device for a rear tire inflation chuck, including a rim bracket, a rear inflation chuck, screws, and a pressure block. The rear inflation chuck is disposed above the rim bracket. The upper surface of the rim bracket is provided with three connecting holes at equal intervals along the circumferential direction. Each connecting hole is provided with a screw, and the screw passes through one end of the pressure block. The other end of the pressure block presses against the inner ring of the rear inflation chuck, and the pressure block can rotate around the screw.

[0005] Furthermore, the pressure block has a fan-shaped block structure, and its distal end presses against the inner ring of the rear inflation chuck.

[0006] Furthermore, the connecting hole includes a threaded hole and a smooth hole arranged coaxially along the longitudinal direction, and the smooth hole is located on the upper side of the threaded hole. The bottom of the pressure block is provided with a sleeve rod, the inner wall of the sleeve rod is slidably connected to the screw, the outer wall is slidably connected to the smooth hole, and the lower side of the screw is connected to the threaded hole.

[0007] Furthermore, a compression spring is fitted on the outer side of the sleeve rod, and the upper and lower ends of the compression spring abut against the bottom of the pressure block and the top of the wheel rim bracket, respectively.

[0008] Furthermore, the inner diameter of the optical hole is larger than the inner diameter of the threaded hole.

[0009] Furthermore, the screw is an internal hexagon screw.

[0010] Compared with the prior art, the beneficial effects of this utility model are:

[0011] This invention uses screws to fix the pressure block to the rear inflatable chuck, thereby achieving a fixed connection between the rear inflatable chuck and the rim bracket. Loosening the screws allows the pressure block to be rotated, disengaging it from the rear inflatable chuck, thus facilitating the disassembly and replacement of the rear inflatable chuck. This connection method allows for the replacement of the rear inflatable chuck without completely removing the screws, effectively improving the replacement efficiency of the rear inflatable chuck, reducing the labor intensity of workers, and lessening the wear and tear on the rear inflatable chuck, thus extending its service life.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0019] It should be noted that all directional indicators (such as up, down, left, right, front, back, etc.) in this utility model embodiment are only used to explain the relative positional relationship and movement of each component in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indicator will also change accordingly.

[0020] In the description of the embodiments, unless otherwise expressly specified and limited, the terms "set," "connect," etc., should be interpreted broadly. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or a connection through an intermediate medium, or it can be a connection within two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0021] like Figure 1-3 As shown, the tire rear inflator chuck quick-change device in this embodiment includes a rim bracket 1, a rear inflator chuck 2, screws 3, a pressure block 4, and a compression spring 5. The rear inflator chuck 2 is disposed above the rim bracket 1. The upper surface of the rim bracket 1 is provided with three connecting holes 6 at equal intervals along the circumferential direction. Each connecting hole 6 is provided with a screw 3, and the screw 3 passes through one end of the pressure block 4. The other end of the pressure block 4 presses against the inner ring 21 of the rear inflator chuck 2.

[0022] Among them, screw 3 is preferably an internal hex screw, for fixing and disassembling respectively; the pressure block 4 is a fan-shaped block structure, and the part with the larger distal end area presses on the inner ring 21 to achieve the fixation of the rear inflation chuck 2.

[0023] The connecting hole 6 includes a threaded hole 61 and a smooth hole 62 arranged coaxially along the longitudinal direction. The smooth hole 62 is located on the upper side of the threaded hole 61. The bottom of the pressure block 4 is provided with a sleeve 41. The inner wall of the sleeve 41 is slidably connected to the screw 3, and the outer wall is slidably connected to the smooth hole 62. The lower side of the screw 3 is connected to the threaded hole 61, and the inner diameter of the smooth hole 62 is larger than the inner diameter of the threaded hole 61.

[0024] The compression spring 5 is sleeved on the outside of the sleeve rod 41, and the upper and lower ends of the compression spring 5 abut against the bottom of the pressure block 4 and the top of the rim bracket 1, respectively. When the screw 3 is loosened, the compression spring 5 pushes the pressure block 4 upward. At this time, the pressure block 4 can be rotated around the screw 3 to disengage it from the inner ring 21, which makes it easy to remove and replace the rear inflation chuck 2.

[0025] When the rear air chuck 2 needs to be replaced, first loosen the screws 3 one by one. Under the action of the compression spring 5, the pressure block 4 is pushed upward, so that it is separated from the inner ring 21 of the rear air chuck 2. Then rotate the pressure block 4 so that its distal end leaves the longitudinal space where the inner ring 21 is located. At this time, the rear air chuck 2 can be removed and a new rear air chuck 2 can be replaced.

[0026] After replacement, rotate the pressure block 4 back into position and tighten the screw 3 so that the pressure block 4 is pressed firmly on the inner ring 21, thereby fixing the rear inflation chuck 2.

[0027] The connection method between the rear inflatable chuck 2 and the rim bracket 1 in this utility model allows for the replacement of the rear inflatable chuck 2 without completely removing the screws 3. This effectively improves the replacement efficiency of the rear inflatable chuck 2, reduces the labor intensity of the workers, and reduces the wear and tear on the rear inflatable chuck 2, thus extending its service life.

[0028] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model. Furthermore, the technical solutions of the various embodiments can be combined with each other, but this must be based on the ability of those skilled in the art to implement them. When the combination of technical solutions is contradictory or cannot be implemented, it should be considered that such a combination of technical solutions does not exist and is not within the protection scope claimed by this utility model.
