Abstract

The invention relates to a measuring tool for multiple round mouth pulsation measurement based on parts. The measuring tool comprises a main body positioning device and a measuring device vertically connected. The main body positioning device mainly comprises a positioning base (1) and a roller frame (2). The roller frame (2) is connected with the right end of the positioning base (1). The measuring device mainly comprises a lever (3), a gauge stand (4) for installing a dial indicator and a measuring head (5), wherein the upper end of the lever (3) is connected with the upper end of the gauge stand (4) for installing the dial indicator, the lower end of the lever (3) is connected with the measuring head (5), and the lever (3) is vertically connected with the positioning base (1). The measuring tool for multiple round mouth pulsation measurement based on parts provided by the invention particularly can ensure accurate measurement of parts, and reduce the manufacturing cost of tools, in particular to measurement of large parts. As the measuring tool is small in size, the measuring tool can be directly placed on the parts, therefore, the measuring tool is light and convenient to use, and is not affected by fields and part placing states.

Description

technical field

[0001] The invention relates to the measurement of the relative runout between multiple circular openings in mechanical manufacturing, in particular to a measuring instrument for measuring the runout of multiple circular openings based on the part itself. Background technique

[0002] Due to the influence of the precision of parts processing and the deformation of parts, there will be a certain deviation in the concentricity between the multiple round openings of the part. The measurement of this deviation is achieved by measuring the circular runout of each round opening. Generally, there are two methods for measuring concentricity. One is to use the round mouth with higher precision as the reference to fix the fit, and measure the runout of other round mouths. The disadvantage of this method is that the measurement accuracy is affected by the positioning reference error and the measuring tool and The fit error of the workpiece has a great influence, and the...
