[0032] The process of completing the above three tasks of the disassembling and assembling upper operating head device of the disassembling and assembling machine disclosed in the present invention is as follows:

[0033] 1. Use the tire shovel wheel to shovel the tire and wheel hub (tire removal process): Figure 7 and Figure 8 As shown, the upper tire removal and installation tool is rotated so that the upper tire removal and installation tool is in the third working position (that is, the tire removal hook and the tire installation column are both in the non-working position), and is locked by the first positioning device;

[0034] Rotate the upper tire bead separation tool so that the upper tire bead separation tool is in the first working position (i.e., the tire scraping wheel is in the working position), and lock it by the second positioning device;

[0035] Then, the tire removal operation can be completed by controlling the tire removal machine. (The specific tire removal process is the same as the operation process of the existing tire removal machine and will not be described in detail)

[0036] 2. Separate the upper bead of the tire from the wheel hub using the tire removal hook (tire removal process): Fig. 9 and Fig.10 As shown, the upper tire removal tool is rotated so that the upper tire removal tool is in the first working position (i.e. the tire removal hook is in the working position), and is locked by the first positioning device;

[0037] Rotate the upper tire bead separation tool so that the upper tire bead separation tool is in the second working position (i.e., the tire scraper wheel is in the non-working position), and lock it by the second positioning device;

[0038] Then, the tire removal hook can be controlled to separate the upper bead of the tire from the wheel hub. (The specific process is the same as the operation process of the existing tire removal machine and will not be described in detail)

[0039] 3. Use the tire mounting column and tire shovel wheel to mount the separated tire on the wheel hub (tire mounting process): Fig.11 and Fig.12 As shown, the upper tire installation and disassembly tool is rotated so that the upper tire installation and disassembly tool is in the second working position (that is, the tire installation column is in the working position), and is locked by the first positioning device;

[0040] Rotate the upper tire bead separation tool so that the upper tire bead separation tool is in the first working position (i.e., the tire scraping wheel is in the working position), and lock it by the second positioning device;

[0041] Then, the tire removal machine can be controlled to complete the operation of installing the separated tire on the wheel hub by using the tire installation column and the tire scraper wheel. (The specific process is the same as the operation process of the existing tire removal machine and will not be described in detail)

[0042] Furthermore, the first positioning device 3 includes a positioning pin seat 30, a positioning pin 31, a spring 32 and a handle 33. The positioning pin seat 30 is fixed on the upper operating head fixing seat 2. The positioning pin seat 20 is provided with a stepped positioning pin installation hole 301. Figure 4 As shown in the figure, the positioning pin 31 includes a locking portion 310, a limiting portion 311 and a connecting portion 312 which are arranged in sequence. Figure 5 As shown, the locating pin 31 is placed in the locating pin mounting hole 301, the spring 32 is sleeved on the connecting portion 312 and is limited in the locating pin mounting hole 301 by the limiting portion 311, and the end of the connecting portion 312 is fixed with the handle 33. In the present embodiment, the handle is a ball-shaped handle, and the handle and the end of the connecting portion are fixed together by threads. Three first locating pin holes 103 are provided on the first tool tray body 100. Pulling the handle can selectively insert or pull out the engaging portion 310 into or out of the three first locating pin holes 103, that is, pulling the handle outward can pull the engaging portion out of the first locating pin hole. At this time, the upper tire disassembly and installation tool can be rotated so that the upper tire disassembly and installation tool is in different work positions. When the upper tire disassembly and installation tool is in the corresponding work position, the restoring force of the spring can push the locating pin so that the engaging portion is inserted into the corresponding first locating pin hole, so that the upper tire disassembly and installation tool is locked in the corresponding work position.

[0043] The second positioning device has the same structure as the first positioning device. The positioning pin seat of the second positioning device is fixed on the second tool plate body. The upper operating head fixing seat is provided with two second positioning pin holes 22. Pulling the handle of the second positioning device can selectively insert or pull out the clamping part into or out of the two second positioning pin holes on the upper operating head fixing seat. Its specific working principle is the same as that of the first positioning device and will not be described in detail here. The specific structure of the positioning device is not limited to the structure described above, and can also be other devices that can lock the upper tire disassembly tool and the upper tire bead separation tool.

[0044] Furthermore, if Figure 3As shown, the upper operating head fixing seat 2 includes two mounting plates 20 and a connecting bottom plate 21. The two mounting plates 20 are arranged oppositely and fixed on the connecting bottom plate 21. The upper tire disassembly and installation tool 10 is installed between the two mounting plates 20. The upper tire bead separation tool 11 is installed on the outer side of one of the mounting plates 20. Two mounting plates are provided, and the upper tire disassembly and installation tool is installed between the two mounting plates, so that the upper tire disassembly and installation tool has better force performance and ensures the service life. At the same time, when the tire removal hook or the tire installation column is in a non-working state, it can be in the space formed between the two mounting plates to avoid interference with other structures, thereby ensuring the smooth progress of the tire disassembly and installation work. At the same time, the upper operating head device of the disassembly and installation machine of the present invention can be conveniently installed on the upper cross arm of the tire disassembly and installation machine through the connecting bottom plate, so as to facilitate the tire disassembly and installation operation.
