Problems solved by technology
[0002] In the process of mechanical manufacturing, when producing high-precision products, since the plane of the ferrule belongs to the positioning reference, the flatness of the outer ring is highly required. The degree of deformation of the plane directly affects the quality of the product. If the deviation of the flatness is too large, The quality of subsequent processing is difficult to guarantee
At present, the flatness measurement method of the bearing outer ring of D20~D60 in the industry is usually to fit the measured plane of the outer ring with a reference plane, and judge whether the flatness meets the requirements by the colored area after color research. This measurement method The application is inconvenient and the measurement results cannot be quantified, the measurement efficiency is low, and the error is large

Embodiment Construction
[0023] The technical solutions provided by the present invention will be described in detail below in conjunction with specific examples. It should be understood that the following specific embodiments are only used to illustrate the present invention and are not intended to limit the scope of the present invention.
[0024] Such as figure 1 and figure 2 The outer ring flatness measuring instrument includes a base 1 and a positioning plate 2 installed on the base. The positioning plate 2 can move back and forth along the base 1. The positioning plate 2 is fixed to the base 1 by bolts. A column 3 is installed on the positioning plate, and a measuring frame 4 is arranged on the column 3 . The measuring frame 4 includes a through hole 5, and a measuring instrument 6 is installed in the through hole 5. In this example, the measuring instrument 6 is a dial gauge. A lever frame 7 is also installed on the measuring frame 4, and the lever frame 7 is connected with the measuring fra...

Description
technical field [0001] The invention relates to the field of measuring instruments, in particular to an outer ring flatness measuring instrument for measuring the flatness of parts. Background technique [0002] In the process of mechanical manufacturing, when producing high-precision products, since the plane of the ferrule belongs to the positioning reference, the flatness of the outer ring is highly required. The degree of deformation of the plane directly affects the quality of the product. If the deviation of the flatness is too large, The quality of subsequent processing is difficult to guarantee. At present, the flatness measurement method of the bearing outer ring of D20~D60 in the industry is usually to fit the measured plane of the outer ring with a reference plane, and judge whether the flatness meets the requirements by the colored area after color research. This measurement method The application is inconvenient and the measurement results cannot be quantif...
