四、振动处理工艺规程拟订和其尺寸精度稳定性检测结果 1.振动处理工艺规程拟订综上所述结论,初步拟订床身铸件的振动处理工艺规程如下: (1)床身铸件经清砂、剖边、喷丸、刷油后进行粗加工,然后按图3所示用特制橡胶垫支承在水泥地基上。 (2)采用专门夹具把激振器固定在床身铸件所要求的位置上,并使其中心线与床身铸件轴线的交角为15度。 (3)调整激振器偏心轮的偏心距为5
V. Vibration Treatment Procedure Specification and Stability Test Results of Dimensional Precision 1. Vibration Treatment Procedure Specification To summarize the above conclusion, the vibration treatment procedure of the bed body casting is preliminarily formulated as follows: (1) The bed castings are cleaned with sand, Cut edge, shot peening, roughing after brushing oil, and then use a special rubber pad as shown in Figure 3 supported on the cement foundation. (2) The special fixtures are used to fix the exciter to the position required by the casting of the bed and make the angle between the center line and the axis of the bed casting be 15 degrees. (3) adjust the exciter eccentric eccentricity of 5
