低压铸造机动模机构平行度分析数据

平行度即通常所说的保持平行的程度，表示零件上被测实际要素相对于基准保持等距离的状况。平行度公差是被测要素的实际方向，与基准相平行的理想方向之间所允许的最大变动量。动模机构平行度是动模精度的一个重要指标，是评估机床加工精度的重要依据之一。动模机构平行度是指工作台板与动模板两平面平行的程度，即其中一平面相对于另一平面平行的误差最大允许值。1、数据检测：将工作台板与动模板的测量平面清洁干净后调整动模板高度，调整到670-730mm采用500mm高度差测量，大于730mm的选择1000mm高度尺。选择4个点位，其中第一个点设定为基准点，将百分表指针指向零位，然后依次测量另外三个点。2、数据采集：依次读出3个测量点的百分表读数，并记录检测数据。3、数据计算：根据三个数值大小，选出最高点和最低点，采用公式计算平行度：平行度=最高点的读数-最低点的读数。4、数据评价：参考GB/T 1184-1996《形状和位置公差未注公差值》的标准，判定平行度公差精度的级别。

Parallelism, commonly referred to as the degree of parallel retention, refers to the state where the actual measured feature of a part maintains an equal distance relative to the datum. Parallelism tolerance is the maximum allowable variation between the actual direction of the measured feature and the ideal direction parallel to the datum. The parallelism of the moving mold mechanism is a critical indicator of moving mold accuracy, and one of the key bases for evaluating the machining accuracy of machine tools. The parallelism of the moving mold mechanism refers to the degree of parallelism between the two planes of the worktable plate and the moving mold plate, specifically the maximum allowable parallel error of one plane relative to the other.
1. Data Detection: Clean the measurement planes of the worktable plate and the moving mold plate, then adjust the height of the moving mold plate to the range of 670-730mm, and use a 500mm height gauge for measurement; if the adjusted height exceeds 730mm, select a 1000mm height gauge. Choose 4 measurement points, set the first point as the datum point, zero the dial indicator, then measure the remaining three points sequentially.
2. Data Collection: Read the dial indicator readings of the three measurement points in sequence, and record the detection data.
3. Data Calculation: Based on the three measured values, identify the highest and lowest readings, and calculate the parallelism using the formula: Parallelism = Reading of the highest point - Reading of the lowest point.
4. Data Evaluation: Refer to the standard GB/T 1184-1996 Standard for Unspecified Tolerance Values of Form and Position Tolerances to determine the accuracy level of the parallelism tolerance.
