On-line measuring device for diameter of wind power bearing raceway

Abstract

The invention discloses an on-line measuring device for the diameter of a wind power bearing raceway. The on-line measuring device can guarantee the quality stability of a product, is arranged on a large-sized vertical numerical control grinding machine and comprises a rotating mechanism, a horizontal guide rail, a measuring rod, a pair of tension springs, a measuring steel ball and a dial gauge, wherein the rotating mechanism is connected to the lower end of a main shaft of the large-sized vertical numerical control grinding machine through a connecting piece; the front part of the lower end of the rotating mechanism is symmetrically connected with a pair of hanging rods; the horizontal guide rail is arranged on the central line of the lower end of the rotating mechanism; the rear end of the horizontal guide rail is connected with a hanging rack; the measuring rod is arranged on the horizontal guide rail in the mode that the measuring rod can move back and forth along the horizontal direction, and is positioned between the pair of hanging rods; the two ends of the pair of tension springs are connected with the lower ends of the pair of hanging rods and the two side faces of the rear part of the measuring rod respectively, so that the measuring rod is under the control of the pre-tightening force of the pair of tension springs; the measuring steel ball is arranged at the front end of the measuring rod; and the dial gauge is inserted into a through hole in the lower part of the hanging rack, and the measuring head of the dial gauge is opposite to the rear end face of the measuring rod.

Description

technical field [0001] The invention relates to an on-line measuring device for the raceway diameter of a wind power bearing. Background technique [0002] At present, in the process of grinding the raceway of the yaw and pitch bearings on the wind turbine, the diameter of the raceway is measured by the indirect measurement method of a micrometer and a steel ball. During the application of this method, the diameter of the raceway cannot be reflected correctly due to human factors, so it is difficult to ensure the stability of the processing size. Based on this, a processing method of matching grinding is adopted, that is, the method of single matching single, but this method is not interchangeable, which not only increases the complexity of the process, but also reduces the efficiency, and can not achieve a higher Second, due to the instability of matching, there are relatively many steel balls used in the same specification, which is also a great problem for the steel ball...
