Method for detecting the coaxiality error of the hirth plate to the central axis

Abstract

The invention discloses a method for detecting the coaxiality error of central axes of mouse tooth disk pair, which comprises the following steps of: a mouse tooth disk pair is installed and a reference mouse tooth disc is fixed. A detection device is respectively propped against the reference outer circle and reference inner circle of the reference mouse tooth disc and synchronously slides alongthe reference outer circle and the reference inner circle so as to obtain a plurality of first meter values corresponding to a plurality of position points on the reference inner circle; and then a detection device is adopted to respectively prop against the reference outer circle and detection inner circle for measuring the mouse tooth disc and synchronously slide along the reference outer circleand the detection inner circle so as to obtain a plurality of second meter values which respectively correspond to a plurality of position points on the detection inner circle corresponding to the reference inner circle one by one. According to the plurality of first meter values and the plurality of second meter values, the coaxiality error of central axes of mouse tooth disc pair is obtained, when the detection method is adopted, the operation steps are simple, the error detection is convenient and fast, the detection period can be greatly shortened, and the production and manufacturing processes of the mouse tooth disc are accelerated.

Description

technical field [0001] The invention relates to the field of hirth detection, in particular to a detection method for the coaxiality error of the hirth to the central axis. Background technique [0002] Hirth is the core component of mechanical indexing equipment. The end face of the Hirth is evenly distributed with many high-precision straight teeth. Hirth is widely used in high-end precision indexing and positioning CNC machine tools and aerospace high-speed and large-torque transmission mechanisms. Such as rotary tables of high-end machine tools, gas turbines and turbine engines, etc. The paired ratchet discs have high meshing requirements, large contact area, strong tooth surface strength and tooth root strength, good positioning rigidity, high repeat positioning and indexing positioning accuracy, automatic centering, and fast positioning speed. Deliver high torque. [0003] The preparation process of the hirth plate is special and complicated, and it depends on the im...
