The invention relates to a measuring method and measuring device for the stick span length of a cylindrical straight tooth involute spline ring gauge. The measuring method provided by the invention comprises the following steps: (1) oppositely installing two symmetric measuring hooks on a measuring base and tailstock of a horizontal length measuring instrument and installing measuring heads on the hook tips of the measuring hooks, wherein the measuring heads comprise a knife edge measuring head and a plane measuring head and the knife edge measuring head and a spline tooth slot of an internalspline are mutually perpendicular; (2) carrying out zero calibration, namely adjusting the two measuring heads to be in parallel; fixing a combined measuring block on an operating platform of the horizontal length measuring instrument by utilizing a measuring block clamp; adjusting the operating platform and enabling the measuring claw operating surface on the measuring block and the knife edge surface of the knife edge measuring head to be parallel; setting the instrument to be zero; (3) taking down the measuring block and installing the measured spline ring gauge, wherein a measuring stick is installed in the tooth slot of the measured spline ring gauge; and (4) enabling the knife edge measuring head to be in contact with the measuring stick; adjusting the operating platform; and reading an indicating value of the instrument and adding the actual value of the measuring block for zero calibration to obtain the stick span length of the measured spline ring gauge.
Description
technical field [0001] The invention relates to a method for measuring the span distance of a spline ring gauge, in particular to a method and a measuring device for measuring the span distance of a cylindrical spur involute spline ring gauge. Background technique [0002] The spline is a coaxial coupling that transmits torque or motion by connecting the two transmission parts with the equidistant distribution on the inner and outer cylindrical surfaces and the same number of teeth. The involute spline is a spline with an involute tooth shape, which is a very important connecting part in the mechanical structure. The involute spline (ring, plug) gauge is the main production line standard gauge for comprehensive inspection of involute splines. [0003] The production of involute spline gauge is a mechanical processing industry derived with the rapid development of the automobile industry, and its production technology has been relatively perfect at home and abroad.
