石材机械直线导轨有哪些组合方式

来源:http://artlabhk.com/ 日期:2020-06-09 发布人:admin

  石材机械直线导轨常见的两种组合:种是双三分离导轨组合。组合都是开放的指导相结合,指导三角形的取向性能变化的尺寸α,α越小解取向,越好,但减少的角度α指导等效摩擦系数,通常限制三角形铁路顶角α越大是90°,重型、大型石材机械,由于大负荷,可取的α= 110°~ 120°。当三角导轨面磨损时,工作台会自动下沉以补偿磨损量。矩形导轨钢度高,加工、检修方便,但定向差。双三角导向器具有较高的方向性和精度保持能力,但由于过度定位,使加工、检测和维护困难。由于石材机械恶劣的工作环境,在切割过程中容易有石粉、水雾和金刚石颗粒飞溅在导轨表面。由于锯切是一种重型切削,直线导轨表面的磨损加剧。目前部分石材机械梁仍采用双三角导轨设计,目的是为了补偿导轨的磨损,在设计加工直线导轨时应满足以下要求。

  There are two kinds of common combinations of stone machine linear guide: the first is the combination of double three separation guide. The combination is the combination of open guidance. The maximum dimension α guiding the change of orientation performance of the triangle, the smaller the α, the better the orientation, but the reduced angle α guiding the equivalent friction coefficient, usually limits the greater the triangle railway top angle α to be 90 °. For heavy and large stone machinery, α = 110 ° ~ 120 ° can be taken due to large load. When the triangular guide surface is worn, the worktable will automatically sink to compensate for the wear. The rectangular guide rail has high rigidity, convenient processing and maintenance, but poor orientation. The double triangle guider has high directionality and accuracy retention ability, but it is difficult to process, detect and maintain because of over positioning. Due to the bad working environment of stone machinery, stone powder, water mist and diamond particles are easy to splash on the surface of the guide rail during the cutting process. Because sawing is a kind of heavy cutting, the wear on the surface of the linear guide rail is intensified. At present, some stone mechanical beams are still designed with double triangular guide rails, in order to compensate for the wear of guide rails, the following requirements should be met in the design and processing of linear guide rails.
  (1)几何精度
  (1) Geometric accuracy
  直线运动导轨的几何精度一般包括:导游在垂直平面直线度(以下简称精度),和线性精密直线导轨在水平面(以下简称B项)准确、并行两直线之间的滑动表面也被称为畸变(C)的准确性,在A, B两个精密导轨直线度和指南中规定每米长度的直线度,精度在C语言中,规则在导轨和导轨长度在每米长度,两个导轨表面之间的畸变量在横向每米长度上的值。上述A、B、C的精度公差可参照机床精度检验的相关标准。
  The geometric accuracy of linear motion guideway generally includes: the guide's straightness in the vertical plane (hereinafter referred to as the accuracy), and the accuracy of linear precision linear guideway in the horizontal plane (hereinafter referred to as item b) and the sliding surface between two parallel lines, which is also called the accuracy of distortion (c). The straightness of two precision guideways A and B and the straightness of each meter length are specified in the guide, and the accuracy is in C language, The rule is that the length of guide rail and guide rail is per meter, and the distortion between the two guide rail surfaces is per meter in the transverse direction. The accuracy tolerance of a, B and C mentioned above can refer to the relevant standards of machine tool accuracy inspection.
  (2)接触精度
  (2) Contact accuracy
  导轨精度精度的精度的接触精度是根据JB2278-78的规定,用接触面占25×25 (mm)面积的百分比或接触点数来测量的。
  The contact accuracy of precision of guide rail is measured according to jb2278-78 by the percentage of contact surface in 25 × 25 (mm) area or the number of contact points.
