Abstract

The invention discloses a device for detecting the shape and depth error of a tooth surface of a mouse tooth disc, which comprises a mounting table, wherein a mounting seat is supported on the mounting table and is used for rotating around the mouse tooth disc. The mounting seat is provided with a slidable contact component which is used for propping against the outer circle of the mounting table.The mounting seat is also provided with a slidable mounting frame, and the mounting frame is provided with a measuring meter. The measuring meter is used for pressing the meter on the inner circle ofthe mouse tooth disc so as to adjust the position of the mouse tooth disc relative to the mounting table, so that the mouse tooth disc is coaxial with the mounting table. The detection device also comprises a measuring rod, and the measuring rod is used for being installing and positioning the tooth-shaped surface to be detected of the mouse tooth disc. A measuring meter head is also used for pressing the meter on the outer circle of the measuring rod so as to find out the maximum value of the meter pressing amount of the generatrix of the outer conical circle of the measuring rod. When the detection device is adopted, the operation is simple, the detection period can be greatly shortened, and the production and manufacturing flow of the mouse tooth disc can be accelerated; in addition, the mouse tooth disc detection device is simple in structure, easy to prepare and high in detection precision.

Description

technical field [0001] The invention relates to the field of Hirth disc detection, in particular to a Hirth tooth surface shape depth error detection device. 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 is special and comp...
