Description

Split type tire loading device for rim Technical Field The utility model belongs to the technical field of vehicle assembly and manufacture, and particularly relates to a split type rim tire loading device. Background The design of the tire loading device directly influences the assembly efficiency, the production cost and the product quality of the tire. In the production process, the reasonable tire feeding device can improve the automation level of tire installation, reduce the complexity of manual operation, thereby improving the production efficiency. In addition, the optimized tire loading structure is beneficial to reducing the loss rate of the tire during installation, improving the consistency and reliability of products and reducing the after-sales maintenance cost. For the tyre adopting the tubeless technology, the high-precision tyre feeding device can ensure the tight fit of the tyre and the rim, and improves the tightness, thereby reducing the reworking rate in the production process and further improving the overall production benefit. At present, tire mounting devices are mainly divided into two types, and each type has certain defects and shortages. The tire feeding device with higher automation degree can improve the assembly efficiency and reduce the manual intervention, but has obvious defects. Firstly, the purchase cost of the equipment is high, enterprises need to invest a large amount of funds for purchase, and the early investment pressure is increased. Secondly, the equipment structure is complicated, contains multiple accurate part, and maintenance and cost of maintenance are higher, in case break down, probably lead to the production line to stagnate, influence whole production efficiency. In addition, such devices typically rely on electrical or pneumatic systems for operation, which can be costly to operate over extended periods of time. Meanwhile, because the automatic tire feeding device is huge in size and large in occupied area, the automatic tire feeding device is not suitable for factories with limited space or flexible adjustment of the layout of a production line. More importantly, the equipment has poor compatibility to tires of different models and specifications, is difficult to adapt to diversified production requirements, and particularly has difficult equipment adjustment in manufacturing environments requiring frequent replacement of the tire types, thereby influencing the production flexibility. The other type is a tire mounting mode completely relying on manual operation, and the tire mounting device has the advantages of low equipment cost and simple operation, but also has a plurality of problems. Firstly, the efficiency of manual installation is lower, the assembly speed is far lower than that of automatic equipment, and the requirement of mass production is difficult to meet. Secondly, the mode relies on the operation proficiency of workman, and there is great difference in different workman installation quality, leads to the product uniformity to drop easily. In addition, manual tire loading is time-consuming and laborious, and intensity of labour is big, and long-term operation probably leads to workman tired, influences production efficiency to the cost of labor increases along with the manpower market changes, makes long-term operation cost not low. Moreover, the tire or rim is easily damaged due to improper operation in the manual installation process, so that the production loss is increased, and the product quality and the after-sale cost are affected. In summary, the two types of tire loading devices in the current market have the defects of high manufacturing cost, difficult maintenance and poor adaptability of the automatic equipment, and the manual installation mode has the defects of low efficiency, high labor intensity and poor quality stability. Therefore, how to reduce the cost and optimize the adaptability while improving the automation level is a key direction of improvement of the current tire loading device.
