Description

Technical Field

[0001] The utility model relates to the field of electrical equipment manufacturing, and more specifically, to a simple running-in tooling with high economic benefits, wear resistance and simple structure. Background Art

[0002] A running-in tooling is a tool or device used for running-in tests of mechanical equipment or components before they are put into use. Traditional running-in toolings may have problems such as complex structure, high cost, insufficient wear resistance and short service life. For example, some running-in toolings require the use of complex transmission mechanisms and expensive components, increasing the production cost and maintenance difficulty. In addition, due to rapid wear, these toolings need to be frequently replaced, affecting production efficiency and economic benefits.

[0003] To solve these problems, it is necessary to develop a simple running-in tooling with high economic benefits, wear resistance and long service life. This kind of tooling should have a simple structure, be easy to operate and maintain, and at the same time be able to meet the requirements of running-in tests. Summary of the Utility Model

[0004] Aiming at the deficiencies of the existing technology, the purpose of the utility model is to provide a simple running-in tooling with high economic benefits, wear resistance and simple structure.

[0006] By adopting the above technical solution, the opening and closing operations of the mechanism are realized. The super-travel compression spring assembly is fixedly connected with the guide rod, and the guide rod vertically passes through the guide sleeve on the bracket. This structural design helps to ensure the stability and accuracy of the super-travel compression spring assembly during the movement process, with a simple structure and strong practicability.
