大批量内螺纹加工,要求100％用通、止螺纹塞规检验,有时通端螺纹塞规不到位,还得进一刀,进刀量很难掌握.极容易使零件报废。每个内螺纹在加工中要检测,最后还得对每个工件用通、止螺纹塞规进行测量,耗费大量人力、物力。为此设计制造了如图所示的内螺纹测量仪。主体1上开有与主体轴线对称的键槽,用来连接固定套3与活动块5,并保证两者的螺纹中轴线与主体轴线在一个平面上。活动块5的两侧面与主体1的键槽滑配,而下部圆柱与滑柱6配合,故可随滑柱6在主体1内左右移动。测量内螺纹前,要按通端螺纹塞规做一个螺纹样板圈。推动手柄7,压缩弹簧4,滑柱6同活动块5上的螺纹样块2一起左移,这时放入螺纹样板圈,放开手柄7,使两块螺纹样块2与螺纹样板圈密配,此时把量程为10毫米的百分表对0 Large quantities of internal thread processing, requiring 100% pass, stop thread plug gauge inspection, sometimes end threading plug gauge is not in place, had to enter a knife, the amount of infertility is difficult to grasp. Very easy to scrap parts. Each internal thread to be tested in the process, and finally have to pass each piece, through the thread plug gauges, consuming a lot of manpower and material resources. Designed and manufactured as shown in the internal thread gauge. The main body 1 is provided with a keyway symmetrical to the main body for connecting the fixing sleeve 3 and the movable block 5 and ensuring that the axes of the two threads are in a plane with the axis of the main body. Both sides of the movable block 5 slide with the keyway of the main body 1, and the lower cylindrical column is matched with the sliding column 6 so that it can move left and right within the main body 1 with the sliding column 6. Before measuring the internal thread, according to the end of the screw plug gauge to do a threaded sample circle. Push the handle 7, the compression spring 4, the spool 6 with the movable block 5 on the left of the screw 2, then put the screw sample circle, release the handle 7, so that the two threaded block 2 and the threaded model circle With, at this time the range of 10 mm dial indicator on the 0
