The workpiece shown in Figure 1 is a zinc alloy die-casting part with a thin hole wall of only 1 mm, φ16.1_(-0.12)~(-0.05)mm, φ15.4_(0.12)~(-0.05)mm and a seal ring therebetween. The groove and the right end are both processed parts. There is a parting line on the outer circle of the bad part φ11.2±0.1mm, and only the inner hole of φ9.3_0~(+0.1)mm is selected as the clamping part. To this end, we designed the fixture shown in Figure 2.
