High-precision gauge for measuring length of gear ring

Abstract

The invention discloses a high-precision gauge for measuring the length of a gear ring. The high-precision gauge comprises a work bench. A mounting block is fixedly connected with the upper r end of the work bench; and a working cavity is formed in the mounting block. A rotating rod groove is formed in the center of the upper cavity wall of the working cavity along a vertical direction; a rotatingrod is installed in the rotating rod groove; and one end, close to the working cavity, of the rotating rod extends into the working cavity. A bearing base is fixedly installed at the bottom of the working cavity. One end, close to the work bench, of the rotating rod is fixedly connected with the inner ring of the bearing base; and a gear wheel is fixedly installed on the rod wall of the rotatingrod in the working cavity. The high-precision gauge is operated conveniently. The gear ring can be fixed on the work bench rapidly and thus the length of the gear ring is measured conveniently, so that a phenomenon that the precision of the value of the gear ring is affected is avoided; the inner ring radius of the gear ring is measured while the gear ring is fixed, so that the gear ring measuringtime is saved and the work efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of workpiece size and length detection, in particular to a high-precision inspection tool for measuring the length and dimension of a ring gear. Background technique [0002] The ring gear is an important part used for transmission in automobiles or other mechanical equipment, and its manufacturing quality directly affects the efficiency and stability of the transmission, especially the guarantee of the dimensional accuracy of the ring gear; in the process of mass production of the ring gear , It is necessary to randomly check the processing quality of the product to avoid batch scrapping due to failure to monitor product quality. [0003] When measuring the length of the ring gear, the ring gear needs to be fixed, otherwise it will affect the numerical accuracy of the measurement, resulting in low dimensional accuracy of the ring gear and affecting the production quality, and traditional measuring instrumen...
