Embodiment
Below in conjunction with accompanying drawing, embodiment of the present utility model is described in detail, but is to be understood that protection domain of the present utility model is not subject to the restriction of embodiment.
Unless separately there is other clearly to represent, otherwise in whole instructions and claims, term " comprises " or its conversion was stated being understood to include as " comprising " or " including " etc. element or ingredient, and do not get rid of other element or other ingredient.
As shown in Figure 3, comprise according to the concrete structure of the testing tool of the threaded hole degree of depth of the utility model embodiment: test hook 1 and shank 2, and slotted countersunk flat head screw 3, wherein, the upper end of test hook 1 is plugged in shank 2, and is screwed in and be fixed by shank 2 side countersunk holes by slotted countersunk flat head screw 3; The lower end of test hook 1 has thread groove hook, under detected state, for catching on the thread groove of threaded hole bottommost, whether then observe tested screw exit end face drops in test hook between two examination criteria grooves of 1, thereby judge whether the tested threaded hole degree of depth meets the requirements, adjust in time process equipment, be adapted at that processing site is measured and quality monitoring.
As shown in Figure 4, test hook 1 is that strip is tabular, comprising: the detection segment and the superposed canned paragraph that are positioned at bottom.The lower end of detection segment is provided with the thread groove hook 11 extending laterally, and thread groove hook 11 is for catching on the thread groove 41 of tested threaded hole 4 inner bottommosts; Whether two examination criteria grooves 12 in the middle part surface mint-mark of detection segment, while measuring the tested threaded hole degree of depth, observe tested threaded hole exit end face and drop between two examination criteria grooves 12, thereby judge that whether this screw hole depth is qualified.
