装配平板它可以有各种不同的强度、硬度、韧性配合的综合性能,装配平板还可兼具一种或多种特殊性能,如耐磨、耐高温和低温、耐腐蚀等,装配平板的尺寸和重量都是可以根据客户的要求定制的,整体的效果好,同时还保证了装配平板质量。
(1)为延长装配平板的使用寿命:保证工作质量。装配平板要先进行回火,精刨,刮研。
(2)为延长装配平板的使用寿命:保证使用精度,刮研接触斑点质量是装配平板的一项重要技术指标。从使用的角度讲,装配平板在不致引起工件与平板发生研合的情况下,尽可能提高接触面积,可提高装配平板的使用寿命。装配平板安装就调至水平板、负荷均匀分布于各支点上。装配平板的环境温度(20±5)℃。使用时应避免振动。
(3)为延长装配平板的使用寿命:在装配平板的使用过程中,要注意避免工件和装配平板的工作面有过激的碰撞,防止损坏装配平板的工作面;工件的重量更不可以超过平板的额定载荷,否则会造成工作质量降低,还有可能损坏装配平板的结构,甚至会造成平板变形,使之损坏,无法使用。
(4)装配平板一般寿命在50年-100年之间,但其平面精度一般正常使用有效其为2年(这也要根据使用频率)
装配平板精度是可修复的,做为晨鑫量具机加工厂来说修复的方法为:铸铁刮研平板在晨鑫机械工厂往往作为平面基准,铸铁刮研平板平面度的好坏直接影响产品质量检测的可靠程度。因为,工厂对检验平板的要求也较高,为确保其准确精度级别,平板的修理也很频繁。
被修装配平板与基准平板进行拖研铲刮,直至被修装配平板的研磨斑点符合要求为止,该方法是最直观,简便,也是最有效的方法,但对基准平板的要求有较好的平面度,且规格必须大于被修装配平板,而基准平板长期使用后也将破原有的平度精度,修复基准平板就比较困难了
装配平板一定要有精准的平面度,要想有精准的平面度必须具备一以下几个条件:
一、装配平板厚度要求:主要包括平台上工作面厚度,侧围厚度和高度,以及底面筋板的厚度、高度和密度。
二、装配平板材质要求:高强度铸铁HT200-300,硬度:HB170-240。
三、装配平板人工退火:在回火窑经过600-700度高温退火时效处理。
四、装配平板自然时效:按国标标准应该是2-3年自然时效,由于此工序时间太长,企业受资金周转影响已不可能等待那么长时间,多以激振器通过振动时效代替。虽然这种工艺的效果尚未明确,但在国际上已普遍使用。
五、装配平板沙眼与气孔:0级与1级平台不允许有气孔与沙眼,2级和3级可以用与平台同材质固体填充气孔沙眼。注意:填充物的的硬度一定要低于平台本身的硬度。
六、装配平板铲刮工艺:人工铲刮在铸铁平台加工过程中是最重要的工艺,它决定了铸铁平台的平面度误差大小,以及工作面的可接触点数。0级板平台在每边为25㎜平方的范围内不少于25点;1级平台在每边为25㎜平方的范围内不少于20点;2级平板平台在每边为25㎜平方的范围内不少于16点;3级平板平台在每边为25㎜平方的范围内不少于12点。铲刮完成后平台四个边棱倒钝。
七、装配平板清砂与涂漆:平台底面清砂要彻底,干净且喷涂红色防锈漆。侧面要平整后再涂漆,一般涂篮漆或绿漆。

八、装配平板 配件选择:主要是支架选择,支架用材为壁厚1.5-2mm的方钢和角铁,焊接密度和结构要合理,调节螺栓要旋转通畅。
九、装配平板安装调试:一般先用用框式水平仪调平,在用光学合像水平仪或电子合像水平仪再进行一次平面度误差测量,如有问题可要求平台生产商来现场铲刮修复。
十、装配平板正确使用:装配平板在调试完成后即可使用
