Method for Grinding Double-angle Tenon-tooth Pair Table Parts

Abstract

The invention discloses a method for grinding a double-angle tenon tooth meter aligning part. The method includes the following steps that a, a process ball is fixedly mounted in the center of the bottom of the meter aligning part to be ground, the relative position between the sphere center of the process ball and the meter aligning part to be ground is fixed, and the sphere center of the process ball is used as a datum point for machining and measuring the meter aligning part to be ground; b, the angle of the meter aligning part to be ground is adjusted according to the datum point, two angle planes of a set of double angle faces of the meter aligning part to be ground are made to located in horizontal planes correspondingly, and surface metering measurement and grinding are carried out; c, the other set of double angle faces opposite to the set of double angle faces are processed by repeating the step b; and d, the molded double-angle tenon tooth meter aligning part is obtained. The dimension precision and the one-time delivery yield of the double-angle tenon tooth meter aligning part are increased, the machining cycle is shortened, and a great quantity of outlay of production is reduced.

Description

technical field [0001] The invention relates to the technical field of aero-engine processing, in particular to a method for grinding a double-angle mortise-tooth pair watch. Background technique [0002] Figure 4 Shown is a schematic diagram of the structure of the double-angle mortise pair table parts that need to be ground. Figure 5 yes Figure 4 C-C section view. Such as Figure 5 As shown, the position of the C-C rotation profile is perpendicular to the center of the body. The C-C rotation section forms an angle of 98°30' with the tenon tooth center line, and an angle of 105°30' with the engine axis. There is a 4°10'9" angle surface in the vertical section direction, and there is an intersection dimension on the angle surface from the aero-engine The axis of the main shaft is 87.5709mm, that is, the center of the mortise teeth of the pair of watches forms a double angle with respect to the axial center of the body of the watch and the axis of the engine, which is a...

Problems solved by technology

[0005] The invention provides a method for grinding double-angle mortise-tooth watch parts to solve the problem that the existing double-angle mortise-tooth pair watch parts processing method cannot measure the machining allowance in real time during the processing process, so that the processing size cannot be grasped. It will result in out-of-tolerance scrapping; and through the three-coordinate detection, it needs to be sent for inspection at any time during the processing process, which is likely to cause detection errors; and frequent inspections lead to technical problems that increase processing costs and processing cycles
