Abstract

The invention discloses a method for detecting the shape and depth error of a tooth surface of a mouse tooth disc, which comprises the following steps of: the mouse tooth disc is installed and positioned. A measuring rod in the detection device is arranged and positioned on a tooth-shaped surface to be detected of the mouse tooth disc. A measuring gauge pressure gauge in the detection device is arranged on an outer circle of the measuring rod and moves along the outer conical circle generatrix of the measuring rod so as to display the maximum pressure gauge value of the outer conical circle generatrix. And the steps are sequentially repeated to obtain the maximum pressure gauge values of a plurality of outer conical circular generatrixes corresponding to a plurality of tooth-shaped surfaces to be measured, and the tooth surface shape and depth error of the mouse tooth disc is obtained according to the maximum pressure gauge values of the plurality of outer conical circular generatrixes. When the detection method is adopted, the operation steps are simple, and the detection period can be greatly shortened.

Description

technical field [0001] The invention relates to the field of Hirth disc detection, in particular to a method for detecting the shape depth error of a Hirth disc tooth surface. Background technique [0002] Hirth parts such as figure 1 As shown, it is the core part of mechanical indexing equipment. The end face of the Hirth plate is evenly distributed with many high-precision straight teeth. The Hirth Plate 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 i...
