Shaft sleeve positioning structure

Abstract

The invention provides a shaft sleeve positioning structure, which is mainly applied to positioning a shaft and a pouring ladle rod. The positioning structure adopts the combination of two basic fastening modes including a clamp-hoop type fastening mode and a pin shaft mode to achieve the shaft sleeve positioning structure which is suitable for working in severe environments, is convenient to mount and maintain, and is suitable for working at high temperature. The structure ensures the safety and the reliability of products and completely achieves the operating requirements.

Description

technical field [0001] The invention relates to a shaft sleeve positioning structure, in particular to a shaft sleeve positioning structure suitable for harsh working environments. Background technique [0002] In the foundry industry, it is necessary to replace and maintain the molten aluminum ladle rod frequently. Due to the harsh working environment, not only the working temperature is as high as 700 degrees, but also in actual work, the molten aluminum will also cover the joint of the two workpieces, providing daily maintenance. Work brings many inconveniences. In addition, since this part has been in a working environment with changes in cold and heat, in order to ensure maintenance and replacement of the ladle rod, the gap between the shaft and the ladle rod is made relatively large. [0003] There are many traditional positioning methods in this part, and the main methods are as follows: [0004] A. The flat key connection method commonly used in general mechanical ...

Problems solved by technology

[0004] A. Adopt the flat key connection method commonly used in general mechanical structures, because in actual work, the ladle must always work in the state of forward and reverse under the state of load, when the equipment is new, it can still be used. After a few months , due to the high temperature environment, the flat key cannot work normally, and the accuracy of pouring is completely lost, so that the quality of the product cannot be guaranteed

[0005] B. There is also a pin shaft to connect the two, but the above-mentioned problems also occur, and the problem cannot be solved

[0006] C. There is another kind, which adopts the form of clamps. Due to the relationship of the working environment, under the action of thermal expansion and contraction, the fastening of the shaft and the rod is still unstable, and there will be loose spots, which will affect the actual work.
