2 试验机零、部件分离面的边沿应划一匀称，不应有明显的错位。门、盖装卸应便当，其分离面的缝隙不应越下表的规则。
2 test machine components separating the edge should be uniform symmetry no misalignment. The door cover handling should be easy the separation of the slit should not go beyond the table rules.大尺寸 缝 隙
Maximum joint gap
≤500mm 1
> 500-1000mm 2
> 1000mm 3
3 埋头螺钉不应突出于零件表面面，其头部与沉孔之间不应有明显的偏心。固定销应突出于零件表面面，外露轴端应突出于容纳件的端面，突出值约为倒棱值。螺栓尾端应略突出于螺母。
3 countersunk screws should not protrude from the surface area its head and between the countersunk apertures should not have the obvious eccentric. Fixed pin should be out of parts surface exposed end of the shaft to accommodate the end pieces should be highlighted highlighting the value of approximately chamfering value.
