Description

Alignment marking tool

Technical Field

The utility model relates to the field of machining of aviation pump products, in particular to an alignment and scribing tool.

Background

An alignment line is usually drawn on the pump for processing convenience of an aviation lubricating oil pump blank, and the alignment line is located in the same plane of the circumference of the pump. The height of the pump is adjusted by the rough-opening blank of the pump through a feeler gauge, so that the alignment lines are positioned at the same height. At present, a method for observing whether the alignment lines are at the same height is to move a circle along the pump through a height gauge to observe whether the alignment lines are at the same height, and if the alignment lines are not at the same height, the height of the pump is adjusted through a feeler gauge and then the alignment lines are observed through the height to observe whether the alignment lines are at the same height.

The method has several disadvantages, one is that the observation of moving the height gauge for a circle is time-consuming; secondly, the height of one position adjusted by the pump may affect the heights of other positions, and the height gauge cannot be observed in real time; thirdly, the part deflection can be caused by the incomplete observation of the height gauge.
