济南阳光板螺丝装置该如何测量?

来源:http://www.wanzhongyue.com/ 日期:2020-08-13 发布人:julong 浏览次数:

济南阳光板工程有很多的细节建设的需要,是什么在起作用? 济南阳光板螺丝装置进行了简要分析测量以下:
Jinan sunshine board project has a lot of details, focusing on the needs of construction, what is working? Jinan sunshine plate screw device was briefly analyzed and measured as follows:
1.螺距的距离过小,有时引起过紧,形式损坏的应力; 这样的距离过大,也会使不稳定固定PC板。螺杆的距离板厚跟随,作为合适的设备。
1. If the distance of screw pitch is too small, sometimes it will cause too tight and damage the stress; if the distance is too large, it will make the PC board unstable. Screw distance plate thickness follow, as appropriate equipment.
2.热胀冷缩是不一样的
2. Heat expansion and cold contraction are different
规模螺丝孔PC板应该考虑夏季和冬季和夜间热膨胀和书的收缩是不一样的。一般地,螺钉应是2的更小孔径?4mm的直径比螺钉大,为了保留空间膨胀。
The size of screw hole PC board should be considered in summer and winter and night thermal expansion and Book shrinkage is not the same. In general, the screw should be 2 with a minimum diameter of? 4 mm, which is larger than the screw in order to retain space for expansion.
3.螺丝孔的方向
3. Direction of screw hole

从螺钉孔太靠近边缘PC板的取向,破碎板非常简单的形式,一般来说,来自PC板的螺钉孔的取向是边际2的螺杆直径。5倍以上。例如,直径4mm螺钉的取向,在来自PC板至少螺纹孔具有比边缘1厘米更。
From the orientation of screw hole too close to the edge of PC board, the broken plate is very simple form. Generally speaking, the orientation of screw hole from PC board is the screw diameter of edge 2. More than 5 times. For example, the orientation of a 4 mm diameter screw has at least 1 cm more than the edge of the threaded hole from the PC board.

4.紧锁螺旋丝切
4. Locking screw cutting
不要过度螺切成丝,或变形,从而导致压力。
Do not over thread or deform, resulting in pressure.
在产品质量和壁厚的相关标准 山东阳光板有严格的要求,减轻重量的做法不符合行业标准。其次,由于落锤 山东阳光板厚度没有减小,使得它可以减少垂直立柱和壁的厚度,印刷电路板的性能将被太阳的影响,如耐跌落冲击性。
In the product quality and wall thickness of the relevant standards, Shandong sunshine plate has strict requirements, the practice of weight reduction does not meet the industry standards. Secondly, because the thickness of the drop hammer Shandong sunshine plate is not reduced, it can reduce the thickness of vertical column and wall, and the performance of printed circuit board will be affected by the sun, such as drop impact resistance.
在另一种情况下,落锤 山东阳光板上下壁厚是标准的,那么它的厚度势必减少螺柱。然而,如由动作的 山东阳光板的主要成分,螺柱螺柱厚度达不到标准,以雪载荷 山东阳光板电阻将下降。
In another case, the thickness of the upper and lower wall of the falling hammer Shandong sunshine plate is standard, so its thickness is bound to reduce the stud. However, if the action of the main components of the Shandong sunshine plate, the thickness of the stud stud can not reach the standard, the resistance of the Shandong sunshine plate will drop under the snow load.
后其基本的落锤绝缘性能济南阳光板不能得到保证,并在同一时间,产品寿命的稳定性将改变。
Jinan sunshine's basic performance after falling hammer will not be guaranteed in the same time.
