Problems solved by technology
[0004] 1. When the bearing is clamped, it is difficult to place the center of the bearing on the measurement diameter, resulting in eccentricity and errors
[0005] 2. Among the above-mentioned measuring instruments, when it is necessary to measure the outer diameter of bearing parts at multiple places, each time the outer diameter of one place is measured, the workpiece needs to be manually rotated to measure the next place, which will increase the measurement error , affecting the quality of the product
[0006] 3. When the above-mentioned measuring instruments need to measure bearings of different sizes, they all need to be positioned by positioning bolts, which makes the measurement process complicated and cumbersome, and affects the measurement efficiency

The invention discloses an outer diameter measuring device and method for an annular part. The measuring device comprises a base, a clamping mechanism arranged in the center of the base, a rotation driving mechanism and a measuring mechanism arranged on the base, wherein the clamping mechanism comprises a clamp body rotationally arranged in the center of the base and a clamp cover arranged at theupper end of the clamp body, the clamp cover is connected with the clamp body through a threaded structure, the rotation driving mechanism is connected with the clamp body, the measuring mechanism comprises eight sets of measuring assemblies, the eight sets of measuring assemblies are evenly distributed around the center circumference of the base, and each set of measuring assembly comprises an installation seat arranged on the base, a measuring rod arranged on the installation seat and a measuring driving mechanism. When the annular part of the device is eccentric in the clamping process, theouter diameter of the annular part can be accurately measured, the accurate position of the annular part on a clamp in the clamping process does not need to be guaranteed, and the measuring process is simple and convenient.
Description
technical field [0001] The invention relates to the technical field of outer diameter measurement of ring parts, in particular to a device and method for measuring the outer diameter of ring parts. Background technique [0002] Ring parts are particularly important for the current machinery industry, such as bearing bushes, bushings, and bearing rings. During the production process of bearing rings, it is necessary to conduct random inspections on the quality of bearing rings. Usually, it is necessary to measure the outer diameter of the bearing to Determine if the bearing ring meets the required specifications. [0003] The existing measuring device for the outer diameter of the bearing ring mainly adopts two-point diameter measuring. For example, the utility model patent whose authorized announcement number is CN206037892U discloses a multifunctional bearing measuring instrument that is easy to locate; the working of the measuring instrument The process is: place the bear...
