Specific embodiment
For making the purpose of this utility model, content and advantage clearer, specific embodiment of the present utility model is made
Describe in further detail.
This utility model provide it is a kind of determines starting point thread detecting device, including determining starting point external screw thread detection means and determine starting point
Internal thread detection device two parts.
Starting point external screw thread detection means is determined as shown in accompanying drawing 1-4, mainly include that screw thread plays point sample circle 3, face mold 1, draws
Line cutting edge 2, handle 4, bearing pin 6 and nut 5, face on the basis of K faces are arranged on the inner face of the unthreaded hole that screw thread plays point sample circle, with
The datum level of external screw thread detected member overlaps, the design basis of detection means benchmark and external screw thread detected member, technological datum one
Cause, the screw thread starting point of external screw thread detected member is relative to the female thread of a central diameter axial location and screw thread point sample circle of datum level
Screw thread starting point is consistent, it is ensured that there is screw thread axial direction, the check point of circumferencial direction technical requirements to be consistent with actually detected point.Line
Model 1 is arranged on screw thread by bearing pin 6 plays point sample circle has on one end end face of screwed hole；Handle 4 is fixed on screw thread by nut 5
Play the outer surface of point sample circle 3.With a line cutting edge 2 and a tolerance line parallel with line cutting edge on face mold 1.Spiral shell
Stricture of vagina plays the outer surface of point sample circle 3 and digs lightening grooves.
Have particular application as：After the completion of the screw thread process of external screw thread detected member, detect qualified with screw gauge first, its
It is secondary by screw thread rise point sample circle screw in part in place after, detect external screw thread detected member screw thread start position, and by rule sample
Plate 1 has marked point identification in part external diameter.
Determine starting point internal thread detection device as shown in Figure 5, mainly include screw thread sample post 7, nut 8, key 9 and handle 10,
The one end of screw thread sample post with positioning step passes through nut 8 and key 9 is fixedly connected with handle 10, and the cylindrical of positioning step is provided with
Line cutting edge, the line cutting edge are overlapped with the cutting edge line of face mold 1, equally, face on the basis of the other end J faces of screw thread sample post,
Determine starting point internal thread detection device benchmark consistent with the design basis of female thread detected member, technological datum, female thread is detected
The screw thread starting point of part plays the externally threaded screw thread starting point phase one of point sample circle relative to central diameter axial location and the screw thread of its datum level
Cause；The screw thread starting point of screw thread sample post must be consistent with the screw thread starting point that screw thread plays point sample circle, must be supporting with sample circle using before
Passed examination, it is ensured that it is consistent with sample post line cutting edge that the trap of two spouse's measurers, i.e. sample iris wipe line tempte.Realize measurer
Transmission sexual function.
Have particular application as：After the completion of the screw thread process of female thread detection piece, detect qualified with screw gauge first, secondly
After screw thread is played point sample post screw-in part in place, screw thread start position delimited, and point identification marked in part end face.
Detected member trap after being scribed together after, the groove on female thread detection piece is located at external screw thread detection piece
Between two grooves, judge that part is qualified.
Determine starting point external screw thread detection means and determine supporting the use for starting point internal thread detection device by above-mentioned, by starting point position
Transmission is put, the final position dimension concordance and interchangeability for ensureing processing spouse's part meets the technical requirements of product.
