Abstract
The utility model provides a detection pin structure for a testing fixture, being able to make the axis of the detection end be consistent with the axis of the to-be-detected hole and to make the detection have high precision and high accuracy. The detection pin structure for a testing fixture includes a detection end and a handle, and is characterized in that the front of the detection end is provided with a guide end; the guide end is cylindrical; the central shaft of the guide end and the central shaft of the detection end are arranged at the same line; the guide end is coordinatively plugged into a positioning hole in the to-be-detected hole; the center shaft of the guide end and the center shaft of the positioning hole are arranged at the same line; and the center shaft of the positioning hole and the center shaft of the to-be-detected hole are arranged at the same line.
Description
Technical field
The utility model relates to the technical field of auto parts and components cubing structure, is specially a kind of test pin structure of cubing.
Background technology
It comprises test side, handle portion the test pin of existing cubing, it is in testing process, the test side inserts in hole to be detected, then detect by go-no go gauge, because the axle center of test side can not be guaranteed consistent with the axle center in hole to be detected, and then can't guarantee the inwall of gaging hole to be checked and the homogeneity in the gap of the periphery of the test side of test pin when causing its go-no go gauge to detect, and so that the precision of detection is not high, poor accuracy.
Summary of the invention
For the problems referred to above, the utility model provides a kind of test pin structure of cubing, itself so that the axle center of test side guarantee consistent with the axle center in hole to be detected so that the precision that detects is high, accuracy good.
A kind of test pin structure of cubing, its technical scheme is such: it comprises test side, handle, it is characterized in that: the front portion of described test side is provided with guide end, described guide end is cylindrical, the central shaft of described guide end and the central shaft of described test side are located along the same line, described guide end cooperation is plugged in the pilot hole of gaging hole to be checked inside, and the central shaft of guide end and the central shaft of described pilot hole are located along the same line, and the central shaft of described pilot hole central shaft and described gaging hole to be checked is located along the same line.
After adopting the utility model, the guide end of test pin cooperates the pilot hole that is plugged in gaging hole to be checked inside, the central shaft of guide end and the central shaft of described test side are located along the same line, the central shaft of guide end and the central shaft of described pilot hole are located along the same line, the central shaft of pilot hole central shaft and described gaging hole to be checked is located along the same line, and then so that the axle center of test side is guaranteed consistent with the axle center in hole to be detected, when detecting, its go-no go gauge guarantees the inwall of gaging hole to be checked and the homogeneity in the gap of the periphery of the test side of test pin, so that the precision of detection is high, accuracy is good.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Embodiment
See Fig. 1, it comprises test side 1, handle 2, the front portion of test side 1 is provided with guide end 3, described guide end 3 is cylindrical, the central shaft of the central shaft of described guide end 3 and described test side 1 is located along the same line, described guide end 3 cooperates and is plugged in the pilot hole 5 of gaging hole to be checked 4 inside, and the central shaft of the central shaft of guide end 3 and described pilot hole 5 is located along the same line, and the central shaft of described pilot hole 5 central shafts and described gaging hole to be checked 4 is located along the same line.
Its principle of work is as follows: the guide end 3 of test pin cooperates the pilot hole 5 that is plugged in gaging hole to be checked 4 inside, the clearance D of periphery that go-no go gauge (not shown in FIG., as to belong to existing mature structure) detects the test side 1 of the inwall of gaging hole 4 to be checked and test pin judges whether gaging hole to be checked 4 is qualified.
