Problems solved by technology

[0004] 1. When the dismounting head is engaged with the rim, the locking rod and the support bolts are severely worn during the locking process, resulting in the hexagonal bar not being locked firmly, so that the dismounting head does not engage with the rim, and the tire gap when installing the tire The parts are easily damaged, seriously affecting the quality of tire loading;
[0005] 2. The locking rod and supporting bolt need to be replaced after wear and tear, which increases the cost of equipment use;
[0006] 3. When rims of different sizes are disassembled, they need to be adjusted first and then positioned, which takes a long time and affects work efficiency

Embodiment 1

[0053] Such as Figure 2-Figure 7 As shown, a positioning and locking device for the hexagonal bar of the tire changer is used for positioning and locking the hexagonal bar of the tire changer, and is convenient for fast positioning and locking of the hexagonal bar 3 .

[0054] The positioning and locking device for the hexagonal bar of the tire changer includes a locking assembly 2 and a locking assembly 14. The locking assembly 2 is located between the swing arm 6 and the hexagonal bar 3, and can be firmly fixed when the tire is dismounted. Lock the swing arm 6 and the hexagonal bar 3, one end of the swing arm 6 runs through the hexagonal bar 3, and its other end is connected with the workbench of the tire changer through a column, and serves as a supporting platform of the present invention.

[0055] There are multiple locking components 2, that is, a multi-point fixing method is adopted. The locking assembly 14 is located on the swing arm 6 and is used for locking multipl...

Embodiment 2

[0067] Such as Figure 2-Figure 9 As shown, a positioning assembly 1 is also included, which is used to quickly locate the hexagonal bar 3 and monitor the displacement change of the hexagonal bar 3 when the tire is disassembled.

[0068] The positioning assembly 1 includes a scale 10 and a laser emitter 12. According to the height of the rim, the laser emitter 12 projects infrared light onto the scale 10 as a marking line. Scale 10 is a scale designed according to the height dimension of different types of rims, which is fixed on the hexagonal bar 3 to mark the height dimension of the rim. Laser emitter 12 and scale 10 are used for positioning, which overcomes the time-consuming problem of needing to adjust and then position when different sizes of rims are disassembled, and realizes the rapid positioning of the hexagonal bar 3 according to different sizes of rims, greatly improving disassembly and assembly tire efficiency.

[0069] Specifically, a slot 9 is provided along t...

Abstract

The invention relates to a positioning and locking device for a hexagonal lever of a tire changer, and belongs to the technical field of tire and rim assembly.The positioning and locking device comprises a locking assembly and a locking assembly, the locking assembly is located between a swing arm and the hexagonal lever and used for locking the swing arm and the hexagonal lever, one end of the swing arm penetrates through the hexagonal lever, and the other end of the swing arm penetrates through the locking assembly; the locking assemblies are located on the swing arms and used for locking the locking assemblies, the hexagonal bar is fixed through the locking assemblies, the defect that due to the fact that locking is not firm in a single-point fixing mode, tire seam allowance parts are damaged is overcome, the tire mounting quality is improved, meanwhile, the locking assemblies are fixed through the locking assemblies, and meanwhile the locking assemblies are fixed to the hexagonal bar through the locking assemblies. The locking assembly drives the multiple locking assemblies to be in linkage, it is guaranteed that all the side faces of the hexagonal bar are evenly stressed, the locking stability and safety of the hexagonal bar are improved, in addition, the hexagonal bar can be rapidly positioned according to rims of different sizes, and the tire disassembling and assembling efficiency is greatly improved.

Description

technical field [0001] The invention belongs to the technical field of tire and rim assembly, and in particular relates to a positioning and locking device for a hexagonal bar of a tire changer. Background technique [0002] When testing the tire performance index, the tire needs to be assembled on the test rim, and the disassembly of the tire and the rim is to press the hexagonal bar on the tire changer to make the bottom disassembly head snap onto the rim and then lock the hexagonal bar. Disassembled. At present, the locking method of the hexagonal bars of the used tire changer is mostly single-point locking and fixing, such as figure 1 shown. The locking action process is as follows: when disassembling the tire, press the hexagonal bar to engage the disassembly head with the rim, and rotate the handle of the locking lever, the support plate is lifted by the supporting bolt to block the hexagonal bar, and the locking action is completed. [0003] There are following def...
