Embodiment Construction

[0025] The embodiments of the present invention will be described in detail below with reference to the accompanying drawings, but the present invention can be implemented in many different ways defined and covered by the claims.

[0026] refer to Figure 1-3 , a preferred embodiment of the present invention provides a method for detecting the parallelism error of a pair of hirth discs. The pair of hirth discs 10 includes two hirth discs 11 that are relatively engaged. The detection method includes the following steps:

[0027] S10: Install and position the Hirth disc pair 10 so that the end face 100 to be detected on the Hirth disc pair 10 faces upwards, and the end face opposite to the end face 100 to be detected faces down as a reference end face.

[0028] S20: Use the detection device to push against the end surface 100 to be detected of the Hirth plate pair 10 and slide relative to the end surface 100 to be detected, so as to display the change of the pressure gauge value...

Abstract

The invention discloses a method for detecting parallelism error of end faces of a mouse tooth disc pair, which comprises the following steps of: a mouse tooth disc pair is installed and positioned sothat end faces to be detected on the mouse tooth disc pair are upwards, and end faces opposite to the end faces to be detected are downwards to serve as a reference end faces. And a detection deviceis used for propping against the end faces to be detected of the mouse tooth disc pair and sliding relative to the end faces to be detected so as to display the change of the pressure meter value of the end faces to be detected. And the end face parallelism error of the end faces to be detected relative to the reference end faces is obtained according to the maximum value of a gauge amount and theminimum value of the gauge amount. When the detection method is adopted to detect the end face parallelism error of the upper end faces to be detected relative to the reference end faces of the mousetooth disc pair, the operation steps are simple, the execution is easy, and the skill requirement on operators is low; the error detection is convenient and fast, the detection period can be greatlyshortened, the production and manufacturing flow of the mouse tooth disc is accelerated, and the detection precision is high.

Description

technical field [0001] The invention relates to the field of hirth detection, in particular to a method for detecting the parallelism error of a pair of end faces of a hirth. Background technique [0002] See Hirth Parts 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 spe...
