Ring measuring device for miniature bearings

Abstract

The invention discloses a ring measuring device for miniature bearings, which comprises a base and a measuring head. The base includes a base plate and a pressing plate movably connected with the base plate. The upper measuring head is installed on the pressure plate, while the lower measuring head is installed on the base plate, and the upper measuring head and the lower measuring head are arranged oppositely; in addition, the measuring head is equipped with a limit block, and the limit block includes The first limit block, the second limit block and the third limit block, the second limit block and the third limit block are respectively arranged on the front and rear sides of the lower measuring head, and the first limit block corresponds to the second limit block The block is fixedly installed on the pressure plate; the third limit block is a door-shaped member, and the beam of the door-shaped member is arranged across the left and right sides of the measuring head. Therefore, the present invention effectively improves the measurement accuracy, and at the same time, the replacement of the measuring head is convenient.

Description

technical field [0001] The invention relates to a ferrule measuring device for a miniature bearing, which belongs to the field of miniature bearing production and manufacturing. Background technique [0002] In the prior art, for the measurement of the outer diameter of the ferrule of the miniature bearing, the measuring head is generally not equipped with a limit block. Therefore, the measurement accuracy is easily affected during the measurement process; at the same time, due to the complexity of the equipment, the measuring head may need to be worn after the measuring head is worn. When the model is changed, it is very inconvenient to replace. Contents of the invention [0003] Aiming at the deficiencies of the prior art, the present invention provides a ferrule measuring device for miniature bearings, which has high measuring precision, which can reach <3 microns, and at the same time, the replacement of the measuring head is convenient and easy. [0004] For reali...
