Abstract

The invention discloses a device for detecting coaxiality and indexing uniform distribution error of a mouse tooth disc pair, which comprises a mounting table, wherein a mounting seat is supported onthe mounting table and is used for rotating around the mouse tooth disc pair. The mounting seat is provided with a slidable contact component, and the contact component is used for propping against the reference outer circle of a reference mouse tooth disc in the process of rotating around the mouse tooth disc along with the mounting seat. 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 correspondingly displaying the change of the meter value of a reference inner circle relative to thereference outer circle or the change of the meter value of the detection inner circle relative to that of the reference outer circle in the process that the contact component props against the reference outer circle and the mounting seat rotates around the mouse tooth disc pair and the meter is pressed on the reference inner circle or the detection inner circle. When the detection device is adopted, the operation is simple, the requirement on skills of operators is low, the detection is convenient and rapid, the cost required by detection can be greatly reduced, the detection period can be greatly shortened, and the production and manufacturing processes of the mouse tooth disk can be accelerated.

Description

technical field [0001] The invention relates to the field of Hirth disc detection, in particular to a device for detecting the uniform distribution error of the Hirth pair of coaxiality and division. 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 disc is special and complicated...
