我们在测试冰箱压缩机电器密封接线柱(图1)时,原采用图2所示夹具,压紧螺杆3与夹具体1为螺纹连接,加压时会产生微量倾斜,工件与夹具体1的密封圈4不能密合。经改进将夹具体与工件接触部分的45°斜面,车出0.5mm高的等腰三角凸台(图3),并淬硬至HRC40～45。满足了18MPa的压力测试. When we test the refrigerator compressor electrical seal terminal (Figure 1), the original use of the fixture shown in Figure 2, the compression screw 3 and the clamp body 1 for the threaded connection, the pressure will produce a slight tilt, the workpiece and the clamp body 1 Seal 4 can not be close together. After the improvement, the 45 ° bevel of the contact part between the clamp and the workpiece is carded out with a 0.5mm high isosceles triangular boss (Figure 3) and hardened to HRC 40-45. Meet the 18MPa pressure test.
