我厂铸造车间每天要在铸件体上取机械性能试样,图中件7所示。每炉要圆环三个,每个平均分割6等分。有时遇到复试时,试样数要成倍增加。所以我们在车床上设计了专用夹具(附图),在车床上铣削6等分机械性能试样,省力省时。在6136 A车床上,在车头卡盘与尾架间装上铣刀11(φ110×2.25)再把车床上小拖板的刀架取下,装上垫圈2和支架3各一件,把己经固紧在托盘8上的试样和托盘缺口中心对准铣刀中 Casting plant in our plant every day to take the mechanical properties of the cast sample, Figure 7 shows the file. Each ring should be three rings, each divided by 6 equally divided. Sometimes encounter retest, the sample number to be multiplied. Therefore, we designed a special fixture on the lathe (with photos), 6 points in the lathe milling mechanical properties of the sample, labor-saving and time-saving. In the 6136 A lathe, a cutter 11 (φ110 × 2.25) is installed between the front chuck and the tailstock, and then the knife holder of the small carriage on the lathe is removed, one each of the washer 2 and the support 3 is installed, The sample and the tray gap center fixed on the tray 8 are aligned with the milling cutter
