Technical Field
[0001] This utility model relates to the field of automotive parts testing technology, and in particular to a dial indicator displacement measuring mechanism. Background Technology
[0002] A dial indicator is a general-purpose length measuring tool made using a precision rack and pinion mechanism. It is primarily used to detect shape and position errors in workpieces. Dial indicators are commonly used for measuring shape and position errors, as well as small displacements. The dial of a dial indicator has 100 equally spaced graduations, with each graduation corresponding to a movement of 0.01 millimeters of the measuring rod. By changing the shape of the probe and adding appropriate supports, various types of dial indicators can be made, such as thickness dial indicators, depth dial indicators, and internal diameter dial indicators. In the automotive industry, dial indicators are essential for inspecting the dimensions of irregular parts.
[0003] However, existing dial indicators require external support frames to prevent them from wobbling during use. But the positioning effect of existing support frames is not ideal, which can easily damage the dial indicator measuring rod. Therefore, there is a need to provide a dial indicator displacement measuring mechanism to solve the above problems. Utility Model Content
