Description

Technical Field

[0001] The invention relates to the technical field of tire dismantling machines, and in particular to a dismantling and assembling lower operating head device of a tire dismantling and assembling machine. Background Art

[0002] With the rapid development of automobile manufacturing industry and the continuous increase of automobile ownership in various countries in the world, the demand for tire disassembly and assembly equipment required for automobile tire maintenance and replacement has increased, and at the same time, the automation degree and work efficiency of tire disassembly and assembly machines are required to be higher. The disassembly and assembly of tires includes the disassembly and assembly of the first layer (i.e., the upper side of the tire) and the second layer (i.e., the lower side of the tire). The disassembly and assembly of the second layer of tires requires the setting of an operating head (i.e., the lower tire operating head) below the tire. During the disassembly and assembly of the second layer of tires, tools such as lower tire mounting columns and lower shovel placenta need to be used. In particular, during the tire mounting process, the lower tire mounting columns and lower shovel placenta need to cooperate with each other to complete their work. The tire mounting columns and shovel placenta of the lower operating head of the existing tire disassembly machine are split structures, and the lower tire mounting columns and lower shovel placenta are driven and controlled by two sets of drive systems and control systems. Therefore, the existing tire disassembly machines have a complex structure and a large volume, as well as complex operation. Summary of the invention

[0003] In view of the above problems, the present invention proposes a disassembly and assembly lower operating head device of a tire disassembly and assembly machine, wherein the lower operating head device integrates a tire loading column and a lower tire shovel disc into an integral structure, thereby simplifying the structure of the tire disassembly machine and reducing its volume.

[0004] The technical means adopted by the present invention are as follows:

[0005] The tire shovel of the second lower disassembly tool is arranged on the lower tire shovel, and the tire shovel of the second lower disassembly tool is arranged on the lower tire shovel. The lower tire mounting tool can rotate around the lower tool rotating shaft, and an arc-shaped displacement groove is provided at the relative positions of the first lower disassembly and assembly tool fixing plate and the second lower disassembly and assembly tool fixing plate. A displacement pin is installed on the lower tire mounting tool body, and both ends of the displacement pin are placed in the displacement groove. When the lower tire mounting tool rotates around the lower tool rotating shaft, the displacement pin moves along the displacement groove so that the lower tire mounting column is in a working position or a non-working position. A displacement tension spring is provided on the outer side of the first lower disassembly and assembly tool fixing plate, one end of the displacement tension spring is fixed on the first lower disassembly and assembly tool fixing plate, and the other end is connected to one end of the displacement pin. The displacement tension spring can lock the lower tire mounting column in the working position or the non-working position through the displacement pin; the lower tire bead separation tool is fixed on the outer side of the second lower disassembly and assembly tool fixing plate.

[0006] Furthermore, the central angle corresponding to the displacement groove is 80-100°.

[0007] Furthermore, a lower tire mounting post accommodating space is formed between the first lower disassembly tool fixing plate and the second lower disassembly tool fixing plate, and when the lower tire mounting post is in a non-working state, the lower tire mounting post is placed in the lower tire mounting post accommodating space.

[0008] Furthermore, the lower tire scraping wheel is installed on the lower tire bead separation tool seat through the lower tire scraping wheel rotating shaft, a bearing is provided between the lower tire scraping wheel rotating shaft and the lower tire bead separation tool seat, and the tire scraping wheel can rotate around the axis of the lower tire scraping wheel rotating shaft.

[0009] Compared with the prior art, the disassembly and assembly lower operating head device of the tire disassembly and assembly machine described in the present invention has the following beneficial effects: the lower operating head device integrates the tire loading column and the lower tire shovel disc into an integral structure, simplifies the structure of the tire disassembly and assembly machine, and reduces the volume of the tire disassembly and assembly machine.

DETAILED DESCRIPTION

[0021] like Figure 1 and Figure 2 The figure shows the disassembly and assembly lower operating head device of the disassembly and assembly machine disclosed in the present invention, including a lower disassembly and assembly tool and a lower disassembly and assembly tool fixing seat 2, the lower disassembly and assembly tool is installed on the lower disassembly and assembly tool fixing seat 2, the lower disassembly and assembly tool includes a lower tire installation tool 10 and a lower tire bead separation tool 11; Figure 4As shown, the lower tire installation tool 10 includes a lower tire installation tool body 100 and a lower tire installation column 101 arranged on the edge of the lower tire installation tool body 100; the lower tire bead separation tool 11 includes a lower tire bead separation tool seat 110 and a lower tire scraping wheel 111 arranged on the lower tire bead separation tool seat 110. In this embodiment, the lower tire scraping wheel 111 is installed on the lower tire bead separation tool seat 110 through a lower tire scraping wheel rotating shaft 112. The lower end of the lower tire scraping wheel rotating shaft is provided with a thread, and the lower tire bead separation tool seat is provided with a threaded hole. A bearing 113 is provided between the lower tire scraping wheel rotating shaft and the lower tire bead separation tool seat, and the tire scraping wheel can rotate around the axis of the lower tire scraping wheel rotating shaft. Figure 3 As shown, the lower disassembly tool fixing seat 2 includes a first lower disassembly tool fixing plate 20, a second lower disassembly tool fixing plate 21 and a connecting bottom plate 22. The first lower disassembly tool fixing plate 20 and the second lower disassembly tool fixing plate 21 are arranged relatively and fixed on the connecting bottom plate 22. The lower tire tool body 100 is installed between the first lower disassembly tool fixing plate 20 and the second lower disassembly tool fixing plate 21 through the lower tool rotating shaft 12. The lower tire tool 10 can rotate around the lower tool rotating shaft 12. An arc-shaped displacement groove 23 is provided at the relative position between the fixed plate 20 and the second lower disassembly tool fixing plate 21. A displacement pin 102 is installed on the lower tire installation tool body 100. Both ends of the displacement pin 102 are placed in the displacement groove 23. When the lower tire installation tool rotates around the lower tool shaft, the displacement pin moves along the displacement groove so that the lower tire installation column is in a working position or a non-working position. That is, the lower tire installation column has two working positions. The first working position: the lower tire installation column is in a working position; the second working position: the lower tire installation column is in a non-working position. Figure 5 The figure shows that the lower tire mounting column is in a non-working position. At this time, when the lower operating head device of the tire dismantling machine is installed on the tire dismantling machine, the lower tire mounting column is in a vertical upward direction and can be used to install the tire. Figure 8 The figure shows that the lower tire installation column is in the working position. At this time, the lower tire installation column rotates around the lower tool rotation axis and enters the accommodating space formed between the first lower disassembly tool fixing plate and the second lower disassembly tool fixing plate.

[0022] A displacement tension spring 24 is provided on the outer side of the first lower disassembly tool fixing plate 20, one end of the displacement tension spring 24 is fixed on the first lower disassembly tool fixing plate 20, and the other end is connected to one end of the displacement pin 102. In this embodiment, one end of the displacement tension spring 24 is fixed to the first lower disassembly tool fixing plate by a bolt 13 and a nut 14, one end of the displacement pin has a groove, and the other end of the displacement spring is hooked in the groove of the displacement pin. The displacement tension spring is in a stretched state, and the tension in the displacement tension spring 24 can lock the lower tire mounting column in a working position or a non-working position; The lower tire bead separation tool is fixed to the outer side of the second lower disassembly tool fixing plate. In this embodiment, the first lower disassembly tool fixing plate, the second lower disassembly tool fixing plate, the lower tire mounting tool body and the lower tire bead separation tool seat all have through holes, and the lower tool rotating shaft passes through the through holes on the first lower disassembly tool fixing plate, the lower tire mounting tool body, the second lower disassembly tool fixing plate and the lower tire bead separation tool seat in sequence and is fixed with a nut 14. In order to prevent the lower tire bead separation tool seat from rotating, the lower tire bead separation tool seat is also fixed to the second lower disassembly tool fixing plate by bolts 13.

[0023] The lower operating head device of the disassembly and assembly machine needs to complete the following tasks during the tire disassembly and assembly process: 1. Use the lower tire-shoveling wheel to shovel the tire and the wheel hub (tire disassembly process); 2. Use the lower tire-shoveling wheel to separate the tire (lower tire rim) and the wheel hub (tire disassembly process); 3. Use the lower tire loading column and the lower tire-shoveling wheel to install the separated tire on the wheel hub (tire installation process).

[0024] The process of completing the above three tasks of the disassembling and assembling lower operating head device of the disassembling and assembling machine disclosed in the present invention is as follows:

[0025] 1. Use the lower tire removal wheel to remove the tire and wheel hub (tire removal process): Turn the lower tire removal tool, such as Figure 6 As shown, the lower tire loading tool is in the second working position (i.e., the lower tire loading column is in a non-working state). At this time, only the lower tire scraping wheel is in the working position, and the tire scraping operation can be completed by controlling the tire removal machine. (The specific tire scraping process is the same as the operation process of the existing tire removal machine, and will not be described in detail)

[0026] 2. Use the lower tire shovel wheel to separate the tire (lower tire bead) and the wheel hub (tire removal process): Turn the lower tire installation tool, such as Figure 7 As shown, the lower tire installation tool is in the second working position (i.e., the lower tire installation column is in a non-working state). At this time, only the lower tire scraper wheel is in the working position, and the tire (lower tire bead) and wheel hub can be separated by controlling the tire removal machine. (The specific separation process is the same as the operation process of the existing tire removal machine and will not be described in detail)

[0027] 3. Use the lower tire installation column and the lower tire shovel wheel to install the separated tire on the wheel hub (tire installation process): Turn the lower tire installation tool, such as Fig. 9 As shown, the lower tire installation tool is in the first working position (i.e., the lower tire installation column is in the working state), and the lower tire scraping wheel is also in the working position, and then the tire removal machine can be controlled to complete the operation of installing the separated tire on the wheel hub by using the lower tire installation column and the lower tire scraping wheel. (The specific process is the same as the operation process of the existing tire removal machine and will not be described in detail)

[0028] Furthermore, a lower tire mounting column accommodating space 25 is formed between the first lower disassembly tool fixing plate 20 and the second lower disassembly tool fixing plate 21. When the lower tire mounting column 101 is in a non-working state, the lower tire mounting column 101 is placed in the lower tire mounting column accommodating space 25. When the tire mounting column is placed in the accommodating space, interference with other components can be avoided, thereby ensuring the safety of operation.

[0029] Furthermore, the central angle corresponding to the displacement groove is 80-100°, so that when the lower tire-mounting column 101 is in a non-working state, the lower tire-mounting column 101 can be completely placed in the lower tire-mounting column accommodating space 25, thereby ensuring the safety of operation.

[0030] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
