Mon Jun 13 16:25:45 CST 2022

1. The secondary alignment method for the root groove of the wheel disc of the combustion compressor unit is characterized in that it is carried out according to the following steps: 1. According to the scribing method of the root groove of the wheel disc of the combustion compressor unit, determine the wheel The center C axis of the disc is at zero degree position; 2. Install the inspection rod slightly smaller than the width of the blade root groove on the CNC machine tool handle, run the centering program, and control the cutting speed to be 50mm/min ~ 100mm/min, so that the inspection rod After entering the central position of the blade root groove, pause the program, use the feeler plug to check both sides of the rod, and adjust the C-axis angle of the CNC machine tool at the same time until the distance between the two sides of the test rod is equal, record the current C-axis absolute coordinate angle, and use this At this time, the angular position offset of C-axis is the zero-degree position of C-axis in the machining coordinate system, that is, C0; 3. Re-align the X-axis center and Y-axis center coordinates of the blade root groove of the wheel disc with the offset C-axis zero-degree position , Take the aligned X0, Y0, C0 as the zero point of the workpiece coordinate system, and align the blade root groove of the gas compressor unit disc, which is completed; among them, the workpiece is the gas compressor unit wheel disc blade root groove. 2. The method for secondary alignment of the blade root groove of a gas compressor unit wheel disk according to claim 1, it is characterized in that the scribing method of the gas compressor unit wheel disk blade root groove in step 1 determines that the wheel The zero-degree position of the center C-axis of the disk, the specific operation is: use a scribe to make the cross center line of the end face of the disk parallel to the X-axis and the Y-axis respectively, and use it as a rough reference for the zero-degree position of the center C-axis of the disk, that is, complete. 3. The method for secondary alignment of the blade root groove of a gas-fired compressor unit according to claim 1, is characterized in that the feeler plug inspection rod both sides in the step 2 refer to using the feeler plug inspection rod both sides If the gap can be entered on both sides of the test rod with the same force and the same thickness, the test rod is plugged in the center of the blade root groove.
