The utility model relates to a joint alignment error edge detection ruler, which belongs to the field of measuring tools in the mechanical industry, and overcomes the difficulty of joint alignment error edge detection in the prior art. Its structure is that the lower end has a ruler scale, the right end is a number of equal-height steps, step height and staggered dimension scale corresponding to the number of steps according to the need to determine, generally 10 to 30. Usage: When measuring, the calibration end of the joint alignment error measuring ruler (1) is placed on the outer surface of the cylinder A (2), and then pushed the measuring ruler (1) so that the step end of the measuring ruler is located on the cylinder B (3). The corresponding calibration value of the step end of the measuring ruler (1) is the alignment error of the welded joint between the cylinder A (2) and the cylinder B (3). The size and the reading method are the same as the ruler. The utility model is not only applicable to the measurement of the misalignment of the longitudinal circumferential welded joint of the pressure vessel cylinder and the circumferential welded joint of the chemical pipeline, but also applicable to the measurement of the misalignment of all the joints.
【技术实现步骤摘要】
接头对口错边量检测尺
本技术属于机械行业检测量具领域,涉及对口错边量的测量。
技术介绍
在压力容器筒体纵环向焊接接头及化工管道环向焊接接头对口时,需要对错边量进行测量,由于受筒体或化工管道摆放的位置和直径大小影响,整圈测量错边量时工作量较大,在测量时须用直尺+卷尺或焊缝检测尺测量检测,比较麻烦;遇到焊缝宽度较大的焊缝检测尺无法测量,遇到直径大的筒体时更是不易操作,难度大且测量误差较大,浪费时间。
技术实现思路
本技术的目的是为了克服现有技术中接头对口错边量检测的困难。一种接头对口错边量检测尺,其结构是下端带有直尺刻度,右端为若干个等高的台阶,台阶高度与错边量尺寸刻度相对应,台阶数量根据需要确定,一般为10至30个。使用方法:测量时将接头对口错边量检测尺1的直尺刻度端靠在筒体A2外表面,然后推动检测尺1,使检测尺1的台阶端靠在筒体B3上,检测尺1台阶端对应的刻度值即为筒体A2与筒体B3的焊接接头对口错边量尺寸,读数方法与直尺相同。本技术的有益效果是,解决了压力容器筒体纵环向焊接接头及化工管道环向焊接接头对口错边量检测的问题。应用灵活方便,提高了测量精度,缩短了检测时间,降低了检测人员的劳动强度。也适用于所有接头对口错边量的测量。附图说明图1为一种接头对口错边量检测尺主视图,图2为一种接头对口错边量检测尺测量筒体环缝错边量示意图,图中:1接头对口错边量检测尺、2筒体A、3筒体B。具体实施方法:结合附图进一步说明本技术。如图1所示,一种接头对口错边量检测尺1,其结构是下端带有直尺刻度,右端为若干个等高的台阶,台阶高度与错边量尺寸刻度相对应,台阶数量根据需要确定,一般 ...
