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 rolling bearing outer diameter multi-section measurement device. The device comprises a support plate, a movable shaft fixedly connected with the lower surface of the supportplate, and a first sleeve connected with the outer surface of the movable shaft in a sleeving manner, wherein the support plate is provided with three radial open slots; a pin roll passing through the movable shaft penetrates through the lower end face of the first sleeve; a cylinder block is arranged on the part, in the movable shaft, of the pin roll in a sleeving manner; a cylindrical cam sleeve is connected with the outer surface of the middle part of the movable shaft in a sleeving manner; the upper end face of the cylindrical cam sleeve is a curved surface having the lowest point, a midpoint A, the highest point and a midpoint B; an idler wheel is arranged on the upper end face of the cylindrical cam sleeve; the idler wheel is fixedly connected with the movable shaft via an idler wheel shaft; a bevel gear A is fixedly connected with the bottom of the cylindrical cam sleeve; a bevel gear B is meshed with the bevel gear A; the bevel gear B is connected with a rotation shaft perpendicular to the movable shaft in a sleeving manner; and a hand wheel is installed at the tail end of the rotation shaft. The device has the beneficial effects that rotation of the hand wheel is converted into a vertical reciprocating motion of the movable shaft, and the moving position of the movable shaft can be accurately controlled by the 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. ...
