Embodiment Construction
[0030] The embodiment of the part height dimension measuring method provided by the present invention, the measuring method in this embodiment comprises the following steps:
[0031] (1) Press the measuring contact of the measuring dial indicator against the upper datum surface of the standard inspection block, adjust the measuring dial indicator to zero, the scale value A of the measuring dial indicator is 0, and the lower datum surface of the standard inspection block It is flush with the lower datum plane of the height dimension of the part to be tested, and the height dimension between the upper and lower datum planes of the standard inspection block is the theoretical height dimension between the upper and lower datum planes of the part to be tested;
[0032] (2) Move the measuring dial gauge until its measuring contact is pressed against the upper datum surface of the part to be tested, and read the scale value B of the measuring dial gauge;
[0033] (3) Subtract the sca...

The invention provides a component height size measuring method and a measuring tool thereof. The method comprise the following steps: (1) a measuring contact of a measuring dial gauge presses against the upper reference surface of a standard check block, the scale value A of the measuring dial gauge is recorded, the lower reference surface of the standard check block is aligned with the lower reference surface of a component to be measured, and the height dimension between the upper reference surface and the lower reference surface of the standard check block is a theoretical height dimension between the upper reference surface and the lower reference surface of the component to be measured, (2) the measuring dial gauge is moves horizontally until that the measuring contact of a measuring dial gauge presses against the upper reference surface of the component to be measured, and the scale value B of the measuring dial gauge is read, (3) through subtracting the scale value A of the measuring dial gauge obtained in step (1) from the scale value B of the measuring dial gauge obtained in step (2), a result is obtained, the result and the height dimension between the upper reference surface and the lower reference surface of the standard check block are added, and the actual height dimension between the upper reference surface and the lower reference surface of the component to be measured is obtained. According to the above method, the height dimension between the upper reference surface and the lower reference surface of the component can be rapidly and accurately measured without any standard measuring tool, and the method is convenient to use.
Description
technical field [0001] The invention relates to a method for measuring the height and dimension of parts and a measuring tool. Background technique [0002] The height dimension of the part is the height dimension between the upper and lower datum planes of the part. When measuring, use measuring instruments such as inner diameter gauges, outer diameter micrometers or vernier calipers with different precision specifications to measure the distance between the upper and lower datum planes, and then get The height dimension of the part to be tested is used to determine whether it is qualified. [0003] However, the above-mentioned measuring tools of different specifications and types, such as inner diameter gauges, outer diameter micrometers or vernier calipers, have poor versatility. Generally, each type of measuring tool corresponds to one type of part size, which has the disadvantage of poor versatility. The problem is that when there are many types of part sizes, there ar...
