According to the depth detection device, the scale is formed in the measuring portion, reading can be performed directly when the depth detection device is placed into the screw hole, detecting efficiency is improved greatly, and the entire measuring process can be completed in about 5 seconds, the reference face can be found rapidly during the measurement through the outer screw thread of the reference portion, the accuracy of the measurement is improved greatly, and the depth detection device is simple in structure, low in machining cost and convenient to operate.
Description
Technical field
The utility model relates to mechanical manufacturing field, particularly a kind of depth detection apparatus of threaded hole.
Background technology
In engine production, the threaded hole quantity on each larger parts is various, from tens to hundreds of.In prior art, quality inspection personnel adopts plug thread gauge to detect the degree of depth of threaded hole, plug thread gauge is screwed in threaded hole, on the position corresponding with the end face of threaded hole, make marks, then plug thread gauge is taken out, measure on plug thread gauge with vernier caliper again, obtain the degree of depth of threaded hole.
The object of threaded hole depth detection be guarantee threaded hole the degree of depth in the deviation range of design, not high to the accuracy requirement detecting, although existing detection method is more accurate, measuring a threaded hole needs 25-30 second, efficiency is very low, causes the production efficiency of engine very low.
The information that is disclosed in this background technology part is only intended to increase the understanding to general background of the present utility model, and should not be regarded as admitting or imply that in any form this information structure has been the known prior art of persons skilled in the art.
Utility model content
The purpose of this utility model is to provide a kind of depth detection apparatus of threaded hole, thereby overcomes the low inefficient defect of engine production that causes of threaded hole depth detection efficiency.
For achieving the above object, the utility model provides a kind of depth detection apparatus of threaded hole, and depth detection apparatus comprises: measurement section, and measurement section is provided with scale; And benchmark portion, one end of benchmark portion is connected with measurement section, the zero point that the end face of the other end of benchmark portion is scale, and under measuring state, the bottom butt of end face and threaded hole.
Preferably, in technique scheme, benchmark portion is provided with the external thread with threaded hole adaptation.
Preferably, in technique scheme, depth detection apparatus also comprises the grip part of being convenient to measurement.
Preferably, in technique scheme, measurement section is the cylinder that is axially arranged with symmetrical cutting plane along it, and one of them cutting plane is provided with scale.
Preferably, in technique scheme, benchmark portion is the cylinder that is axially arranged with symmetrical cutting plane along it, and the external diameter of benchmark portion is greater than the external diameter of measurement section.
Compared with prior art, the utlity model has following beneficial effect:
Measurement section of the present utility model is provided with scale, in the time that depth measurement device is placed in threaded hole, just can directly read, and has greatly improved detection efficiency, and whole measuring process can complete about 5 seconds; When the external thread of benchmark portion makes to measure, find very soon reference field accurately, the accuracy of measurement improves greatly; The utility model is simple in structure, and processing cost is low, and simple operation.
