为了将垫圈外圆车小,可采用切削力夹紧心轴(见图),夹紧力可靠。垫圈为冲压件,在周边上存在厚薄不均的问题,当厚点被加工去掉时,垫圈之间必然出现间隙而产生松动,采用切削力夹紧心轴,这种间隙便能得到及时补偿。使用时,垫圈从螺母6处穿入,拧紧螺母,将夹具置于两顶尖之间,在圆 In order to bee wheel cylindrical small, cutting force can be used to clamp the mandrel (see photo), clamping force and reliable. Washers for the stamping parts, the thickness of the uneven existence of the problem on the periphery, when the thickness is removed when processing, the inevitable gap between the washers and loose, the use of cutting force clamping mandrel, this gap will be promptly compensated. When used, the washer penetrates through the nut 6, tightens the nut, places the clamp between the two centers,
