Abstract
The utility model relates to a measuring tool for measuring degree of symmetry of a cylinder cover air valve pipe hole axis to two sides of guide pillar keyway. An indicating gauge is inserted into a hole with an open sleeve on a measuring plate, a fastening screw is tightly screwed, and a 0.5 millimeter compression margin is left. A T-shaped indicating gauge measuring head is screwed in a screw of an indicating gauge measuring rod, a cylindrical pin is inserted into the air valve pipe hole with no clearance, an excircle of the cylindrical pin is analogue to the air valve pipe hole axis, the cylindrical pin is arranged at the upper portion of the air valve pipe hole, and the cylindrical pin excircles which a longitudinal surface of the measuring plate bears against serve as references. One side of the T-shaped indicating gauge measuring head is inserted into a guide pillar keyway and is disposed at the right side of the guide pillar keyway, and the longitudinal surface of the measuring plate bears against the two excircles of the cylindrical pin which serve as references. After the indicating gauge is compressed, data displayed is a. The measuring tool is rotated by 180 degrees, the same method is adopted for measuring the left side of the guide pillar keyway, and after the indicating gauge is compressed, data displayed is b. So, the symmetry degree of the cylinder cover to the guide pillar keyway is the absolute value of the difference between a and b. The measuring is simple and fast, and data is precise.
Description
Technical field
The utility model relates to a kind of measuring appliance of mechanical component size, and especially cylinder cover valve guide bushing axially bored line is to guide pillar keyway symmetria bilateralis tolerance tool.
