参考图1至图2，本实用新型涉及一种新型背板扭曲度量测治具，包括一长条状底座1和一垂直于底座的垂直挡墙2，所述底座上连接有一平行于垂直挡墙底边的滑动挡墙3，所述滑动挡墙与垂直挡墙之间形成用以置纳背板底部的容置空间4，所述垂直挡墙的一侧上角设置有一沟槽5，所述沟槽具有一滑块6。 Referring to Fig. 1 to Fig. 2, the utility model relates to a new type of backplane twist measurement fixture, which includes a strip-shaped base 1 and a vertical retaining wall 2 perpendicular to the base, the base is connected with a The sliding retaining wall 3 at the bottom of the retaining wall, an accommodating space 4 for accommodating the bottom of the backboard is formed between the sliding retaining wall and the vertical retaining wall, and a groove 5 is provided at the upper corner of one side of the vertical retaining wall , the groove has a slider 6 .
上述垂直挡墙的另一侧上设置有用以表示不同背板尺寸的标识孔7。 The other side of the above-mentioned vertical retaining wall is provided with identification holes 7 for indicating different sizes of backboards.
上述底座上设有两道平行的滑道8，所述滑动挡墙的底侧设有用以安设于滑道内的凸部9。 The base is provided with two parallel slideways 8, and the bottom side of the sliding retaining wall is provided with a convex part 9 for being installed in the slideways.
具体实施过程： The specific implementation process:
该治具的功能如下：底座容置空间用于放置和定位背板，背板尺寸标识用于识别不同尺寸的背板。滑块可以依据不同背板的扭曲度限制，做不同厚度，并且滑块可以在沟槽中移动和固定，以适应不同尺寸背板的要求。 The functions of the jig are as follows: the accommodating space of the base is used to place and position the backplane, and the size mark of the backplane is used to identify backplanes of different sizes. The slider can be made of different thicknesses according to the twist limit of different backplanes, and the slider can be moved and fixed in the groove to meet the requirements of different size backplanes.
使用前，先设置滑块高度，如背板的扭曲度规格为≤2mm，则使用2mm的滑块。并调整滑块到相应尺寸背板范围内。 Before use, set the height of the slider. If the twist of the backplane is ≤2mm, use a slider of 2mm. And adjust the slider to the range of the corresponding size backplane.
而后，将治具直立，背板放置于垂直挡墙和底座滑动挡墙形成的容置空间中，背板上侧自然靠在垂直挡墙上。 Then, the jig is upright, the backboard is placed in the accommodation space formed by the vertical retaining wall and the sliding retaining wall of the base, and the upper side of the backboard naturally leans against the vertical retaining wall.
首先测背板上侧两个边角的扭曲度，做法为： First, measure the twist of the upper two corners of the backplane, as follows:
测背板左上侧的扭曲值： Measure the twist value on the upper left side of the backplane:
按压背板右上角，使背板右上侧接触滑块，同时查看背板左上侧是否会碰到垂直挡墙，（原理：背板右上侧由于滑块阻挡，与垂直挡墙距离2mm，若背板平直无扭曲，背板左上侧也应与垂直挡墙距离2mm） Press the upper right corner of the back panel so that the upper right side of the back panel touches the slider, and at the same time check whether the upper left side of the back panel touches the vertical barrier (principle: the upper right side of the back panel is blocked by the slider, and the distance from the vertical barrier is 2mm. The board is straight without distortion, and the upper left side of the back board should also be 2mm away from the vertical retaining wall)
若左上侧碰到垂直挡墙，则左上侧扭曲值超标。 If the upper left side touches the vertical retaining wall, the distortion value of the upper left side exceeds the limit.
若左上侧与垂直挡墙有间隙，则判定OK，此时可用塞规确认间隙宽度，并计算背板向垂直挡墙方向扭曲值（简称“向内扭曲值”）为2mm-间隙宽度。 If there is a gap between the upper left side and the vertical retaining wall, it is judged OK. At this time, the gap width can be confirmed with a plug gauge, and the twist value of the backplane to the vertical retaining wall (referred to as "inward twist value") is calculated as 2mm-gap width.
测背板右上侧的扭曲值： Measure the twist value on the upper right side of the backplane:
按住背板左上角，使背板左上侧接触垂直挡墙，同时查看背板右上侧是否会碰到滑块， Press and hold the upper left corner of the backboard so that the upper left side of the backboard touches the vertical retaining wall, and at the same time check whether the upper right side of the backboard touches the slider,
若背板右上侧碰到滑块，则右上侧扭曲值OK。 If the upper right side of the backplane touches the slider, the upper right twist value is OK.
若背板右上侧和滑块之间有间隙，则判定背板右上侧背对垂直挡墙方向扭曲值（向外扭曲值）NG，同样，可以用塞规确认背板右上侧与滑块的间隙宽度，该宽度即为向外扭曲值超过上限的值。 If there is a gap between the upper right side of the backboard and the slider, it is judged that the upper right side of the backboard faces away from the vertical retaining wall and the twist value (outward twist value) is NG. Similarly, the upper right side of the backplane and the slider can be confirmed with a plug gauge. Gap width, which is the value by which the outward twist value exceeds the cap.
将背板上下调转方向，重复上述1、2方法，测量余下两个边角的扭曲值。 Turn the backplane up and down, repeat the above 1 and 2 methods, and measure the twist value of the remaining two corners.
因背板扭曲度为双向的，因此只需在按压一边后，量测其对应的另一边翘起的数值，通过使用指定厚度的滑块(厚度需可允许的最大扭曲度)，可以迅速确认此背板是否超规，检验简单迅速。 Because the twist of the backplane is bidirectional, it is only necessary to measure the warping value of the other side after pressing one side. By using a slider with a specified thickness (thickness needs to allow the maximum twist), it can be quickly confirmed Whether the backplane is out of specification, the inspection is simple and quick.
以上所述仅为本实用新型的较佳实施例，凡依本实用新型申请专利范围所做的均等变化与修饰，皆应属本实用新型的涵盖范围。 The above descriptions are only preferred embodiments of the present utility model, and all equivalent changes and modifications made according to the patent scope of the present utility model shall fall within the scope of the present utility model.
