Problems solved by technology
[0003] The technical problem to be solved by the present invention is that the existing measuring device and method for measuring the outer diameter of rolling bearings can only measure the outer diameter of a section, and the rolling bearing needs to be reversed during the measurement, and only the conical shape of the outer diameter can be detected. To detect the special shape of concave or convex, and provide a multi-section measuring device for the outer diameter of rolling bearings

The invention discloses a multi-section measuring device for the outer diameter of a rolling bearing. To the opening groove, the lower end surface of the first sleeve is penetrated with a pin shaft passing through the moving shaft, and the part of the pin shaft located in the moving shaft is covered with a cylindrical block; the outer surface of the middle part of the moving shaft is sleeved with a cylindrical cam sleeve. The upper end surface of the cam sleeve is a curved surface with the lowest point, the middle point A, the highest point and the middle point B. The upper end surface of the cylindrical cam sleeve is provided with a roller, which is fixedly connected to the moving shaft through the roller shaft. The cylindrical cam sleeve A bevel gear A is fixedly connected to the bottom, and the bevel gear A meshes with a bevel gear B. The bevel gear B is sleeved on a rotating shaft perpendicular to the moving shaft, and a hand wheel is installed at the end of the rotating shaft. The beneficial effect of the invention is that the rotation of the handle wheel is transformed into the up and down reciprocating motion of the moving shaft, and the moving position of the moving shaft can be accurately controlled by a mechanism.
Description
technical field [0001] The invention relates to the field of bearing manufacturing, in particular to a bearing precision measuring instrument. Background technique [0002] Rolling bearings are precision mechanical parts, and the processing accuracy of their rings is very high. Such high-precision measurements can only be determined with precision instruments. The purpose of checking the outer diameter of the bearing ring is to ensure that the product quality meets the requirements of the national standard. The outer diameter measuring instrument is mainly used to measure the dimensional accuracy and geometric accuracy of the outer diameter of the bearing ring, and can also measure the non-perpendicularity of the outer diameter to the end face and Bearing ring height dimension and end face parallelism. Such as Figure 1-3 As shown, "Harbin Bearing" Volume 27, No. 1, March 2006 disclosed the method of adjusting and aligning the bearing outer diameter measuring instrument. ...
