铝合金门窗设备出厂前设备检验!

来源:http://www.tianxincnc.cn/ 发布时间:2022-02-15
零件的几何精度包括尺寸、形状和表面位置精度。经常检查的项目有尺寸、圆柱度、圆度、平面度、直线度、同轴度、平行度、垂直度和跳动等。根据维修的特点,有时不要求单件的几何尺寸,而要求相对配合精度。
The geometric accuracy of parts includes the accuracy of size, shape and surface position. The frequently checked items include dimension, cylindricity, roundness, flatness, straightness, coaxiality, parallelism, perpendicularity and runout. According to the characteristics of maintenance, sometimes the geometric dimension of a single piece is not required, but the relative matching accuracy is required.
零件的表面质量包括表面粗糙度,表面是否有划痕、腐蚀、裂纹、脱落、烧焦、咬合等缺陷。
The surface quality of parts includes surface roughness and whether there are scratches, corrosion, cracks, falling off, scorching, bite and other defects on the surface.
除硬度、硬化层深度外,还应根据情况对零件在制造和修理过程中形成的应力状态、平衡状态、弹性、刚度、振动等物理机械性能进行适当检测。
In addition to the hardness and the depth of hardened layer, the physical and mechanical properties such as stress state, equilibrium state, elasticity, stiffness and vibration formed during the manufacturing and repair of parts shall also be properly tested according to the situation.

零件的隐性缺陷包括制造过程中的内部夹渣、孔隙、气孔、空隙、焊缝等缺陷,以及使用过程中产生的微观裂纹。
The hidden defects of parts include internal slag inclusion, pores, pores, voids, welds and other defects in the manufacturing process, as well as micro cracks in the use process.
零件的质量和静平衡,如活塞和连杆的质量差异,曲轴、风扇、轴、轮等高速旋转的零件的静平衡。
The mass and static balance of parts, such as the mass difference between piston and connecting rod, and the static balance of crankshaft, fan, shaft, wheel and other high-speed rotating parts.
零件的材料性能,如零件的合金成分、渗碳层的含碳量、各零件材料的均匀性、中石墨的去除情况、橡胶材料的老化变质程度等。
Material properties of parts, such as alloy composition of parts, carbon content of carburized layer, uniformity of materials of all parts, removal of graphite in, aging and deterioration degree of rubber materials, etc.
