Description
技术领域technical field
本实用新型涉及一种准确检测沉头螺栓P值的量规。The utility model relates to a gauge for accurately detecting the P value of countersunk head bolts.
背景技术Background technique
该零件为HB类常用沉头螺栓，此类螺栓年需求量非常大。在测量头部P值，如图1所示0.71尺寸时，传统的检测手段是采取游标卡尺配合常规量筒测量，此种方法测量，影响测量值的因素有：1、套筒磨损后，D2的φ7.71尺寸变大，测量的P值比实际值要小；2、杆部d不能定位时，产品会放置不平，影响测量结果。因此，常规方法测量，靠点接触，锥面直线度不好，量具磨损，产品端面不平，放置不稳都会影响测量结果，使得结果误差较大。由于现在很多客户对此一致性的要求比较严格，需要准确的结果，因此，针对此情况能设计出一个能便捷、准确的检测量具尤为重要。This part is a commonly used countersunk head bolt of type HB, and the annual demand for such bolts is very large. When measuring the P value of the head, as shown in Figure 1, when the size is 0.71, the traditional detection method is to use a vernier caliper to measure with a conventional measuring cylinder. The factors that affect the measured value of this method are: 1. After the sleeve is worn, the φ7 of D2 .71 The size becomes larger, and the measured P value is smaller than the actual value; 2. When the rod part d cannot be positioned, the product will be placed unevenly, which will affect the measurement result. Therefore, the conventional method of measurement relies on point contact, the straightness of the cone surface is not good, the measuring tool is worn, the end surface of the product is uneven, and the placement is unstable, all of which will affect the measurement result, resulting in a large error in the result. Since many customers now have strict requirements on this consistency and need accurate results, it is particularly important to design a convenient and accurate measuring tool for this situation.

When measuring, take the E surface as the benchmark, measure the product with a dial indicator, and see how much the product end surface is lower than the E surface or higher than the E surface. The final measurement result has small error and good consistency, which can meet the measurement requirements of countersunk head bolt P value. The gauge has the advantages of simple structure, strong practicability, easy operation and low manufacturing cost, and can be popularized and applied in the machining industry.
