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 a device and method for measuring the outer diameter of an annular part. The measuring device includes a base, a clamping mechanism arranged in the center of the base, a rotating drive mechanism and a measuring mechanism arranged on the base; the clamping mechanism includes a rotating device The clamp body at the center of the base, the clamp cover arranged on the upper end of the clamp body, the clamp cover is connected with the clamp body through a thread structure; the rotation drive mechanism is connected with the clamp body; the measuring mechanism It includes 8 sets of measuring components, which are evenly distributed around the center circumference of the base, and each set of measuring components includes a mounting base set on the base, a measuring rod set on the mounting base, and a measuring drive mechanism. When the ring part of the device is eccentric during the clamping process, the outer diameter of the ring part can be accurately measured without ensuring the precise position of the ring part on the fixture during the clamping process, and the measurement process is simple and convenient.
Description
technical field [0001] The invention relates to the technical field of outer diameter measurement of annular parts, in particular to an outer diameter measurement device and method of annular parts. Background technique [0002] Ring parts are particularly important for the current machinery industry, such as bearing bushes, bushings and bearing rings, etc. During the production process of bearing rings, the quality of the bearing rings needs to be sampled, and the outer diameter of the bearing usually needs to be measured. Determine if the bearing ring meets the required specification. [0003] The existing outer diameter measuring device of the bearing ring mainly adopts the diameter of two points to measure the diameter. For example, the utility model patent with the authorization announcement number CN206037892U discloses a multifunctional bearing measuring instrument that is easy to locate; the working of the measuring instrument is The process is: place the bearing on...
