Problems solved by technology

[0002] Bearings are an important part widely used in modern mechanical products. With the continuous invention and creation of people, the requirements for bearings are getting higher and higher, and the requirements for their accuracy are becoming more and more stringent. Therefore, a high-precision bearing inner diameter measurement The device came into being. There are many kinds of such devices on the market today, which are suitable for the measurement of various bearings, but there are still some problems. Most of these devices on the market today use a measuring ruler to measure the inner diameter of the bearing, but ignore In order to measure the thickness of the ruler arm, the measurement of the inner diameter of the bearing is not accurate enough, which affects the use

Abstract

The invention discloses a high-precision bearing bore diameter measuring device. The device comprises a fixing block, a measurement plate, an infrared emitter and a base plate, wherein limiting blocks are arranged at the two ends of the base plate, a control box is installed above the limiting blocks, a display screen is installed at the top end of the control box, an electromagnetic guide rail is installed above the base plate, a first sliding block is installed in the middle of the electromagnetic guide rail, the infrared emitter is installed at the center of the upper side of the first sliding block, and a first fixing plate and a second fixing plate are both connected with a sliding chute through the sliding block. According to the device, traditional measurement conducted with a measuring scale is not adopted, infrared measurement is adopted, and measurement accuracy is improved; meanwhile, movement of the sliding block is controlled through the electromagnetic guide rail, automatic measurement is achieved, and artificial error is reduced.
