Embodiment Construction

[0030] The present invention will be further described below with reference to the embodiments and the accompanying drawings.

[0031] A processing method for the axial positioning surface of a turntable frame, such as Figure 1-Figure 10 As shown, the method includes the following steps:

[0032] (1) First, three coplanar fixed surfaces 36 and three coplanar support surfaces 37 are processed on both sides of the U-shaped frame 1, and then the U-shaped frame 1 is placed on the machine table 11 so that three The support surface 37 is in contact with the machine tool table 11 at the same time. After adjusting and calibrating the position of the U-shaped frame 1, the three fixing surfaces 36 on the U-shaped frame 1 are pressed by the three clamps 38 to fix the U-shaped frame 1 on the machine tool table. 11;

[0033] (2) Fix the machine tool 15 on the machine tool spindle 16, first process the B pitch bearing seat surface 7 at one end of the U-shaped frame 1, and fix the B mirro...

Abstract

The invention discloses a processing method for the axial positioning surface of a turntable frame. The pitching bearing seat surfaces A and B on the U-shaped frame are processed by an autocollimator, a machine tool table, a lifting bracket and a double-sided mirror. Axial positioning surface machining. Utilizing the advantages of autocollimator and double-sided mirror with high measurement accuracy in a small range, the autocollimator measurement technology is introduced into machine tool processing, and the on-line measurement of the axial positioning surface of the turntable frame and the parallelism error can be measured, and the parallelism error can be measured. It can be repaired and processed. Through the whole processing process, the parallelism error of the axial positioning surface of the turntable frame can meet the design requirements.

Description

technical field [0001] The invention relates to a processing method for the axial positioning surface of a turntable frame. Background technique [0002] The precision of the pitch or roll shaft system of the inertial navigation test equipment includes two aspects: mechanical precision and control precision. Among them, mechanical precision is the basis for realizing control precision; mechanical precision is mainly reflected by the rotation precision of the shaft system. The shafting rotation accuracy is determined by the machining accuracy of the positioning surface of the U-shaped frame bearing assembly, the coaxiality of the positioning hole of the U-shaped frame bearing assembly, the accuracy of the bearing assembly, the positioning surface of the O-shaped frame spindle, and the final assembly accuracy. Therefore, the U-shaped frame bearing assembly is improved. The machining accuracy of the positioning surface and the positioning surface of the main shaft of the O-fram...
