Embodiment Construction

[0047] The technical solution of the present invention will be further described below in conjunction with the accompanying drawings, but the claimed protection scope is not limited to the description.

[0048] Such as figure 1 As shown, the processing device in this embodiment adopts a precision vertical boring machine, including a boring machine adapter table 1; a first tooling fixture 2; a diamond roller 3; a boring machine spindle 4; a grinding wheel 5; a second tooling fixture 6; Processing standard parts 8; third fixture 9. The grinding wheel 5 is driven by the air gun 7, and the air gun 7 is connected to the main shaft 4 of the boring machine through the second fixture 6.

[0049] Among them, such as Figure 9 ~ Figure 14 As shown, the third fixture 9 includes a base plate 91, a positioning block 92, a pressing block 93 and a first screw 94; the positioning block 92 is detachably connected to the upper end surface of the base plate 91, and the upper end surface of th...

Abstract

The invention discloses a processing device and method for arc teeth of a standard part of a round bar of a compressor rotor blade. A boring machine is used as the processing device, and a diamond roller (3) is connected to a boring machine transfer table (1) through a first fixture (2). ), the boring machine transfer table (1) is connected with the standard part (8) to be processed through the third tooling fixture; the grinding wheel (5) is connected with the boring machine main shaft (4) through the second tooling fixture (6). The present invention drives the standard parts (8) to be processed by rotating the boring machine transfer table (1) to process the circular arc, which gets rid of the limitation that the forming grinding wheel on the grinding machine can only process a single size, and can adjust the standard parts (8) to be processed The radius from the center of rotation is used to process the inner and outer arc dimensions of different product designs.

Description

technical field [0001] The invention belongs to the field of mechanical processing, and in particular relates to a processing method and a processing device for a circular arc tooth surface of a cylindrical standard part. Background technique [0002] Such as Figure 17 and Figure 18 As shown, it is a round rod standard part. The main technical difficulties in processing the upper dimension of the round rod standard part of the circular arc tooth compressor rotor blade are: the tolerance of the arc size and the T line size of the round rod standard part is 0.01, and the requirements are particularly strict. Angle and surface finish requirements are relatively high, because the tenon is symmetrical, it must be clamped twice to ensure the consistency of the processed size; it is necessary to ensure the arc size of the standard part of the round rod, the tolerance of the T line size and the relative angle and higher The design requirements of the surface finish can achieve th...
