Abstract
The invention discloses a detecting pin for an automobile sheet metal part test tool. The detecting pin comprises a handheld part, a detecting part and a guide part, the handheld part, the detecting part and the guide part are connected in sequence, a line carving needle is arranged on one side of the detecting part, the axial direction of the line carving needle is consistent with that of the detecting part, the needle head of the line carving needle is fixedly connected with the end face of the handheld part, and when the guide part is inserted into a detecting hole in the test tool, the end, away from the handheld part, of the detecting part can penetrate through a sheet metal part to be detected, and the line carving needle can be in contact with the sheet metal part. According to the detecting pin, a kidney-shaped hole in the sheet metal part can be fast detected, detecting speed is high, and precision is high.
Description
Technical field
The present invention relates to cubing, particularly relate to a kind of automobile metal plate work cubing test pin.
Background technology
In the process such as punching press, welding of Metal Sheets for Body-manufacturing, in order to ensure the size coupling between part, single part just needs carry out size monitoring to these low profile.In testing process, normally sheet metal component is assembled in corresponding cubing, is then detected the position of the mounting hole, pilot hole etc. of sheet metal component by test pin, and detect the gap etc. between sheet metal component and cubing by detection ruler.
Current test pin is mostly column structure, comprise targeting part and the detecting portion of coaxial setting, by targeting part test pin inserted in the detect aperture in cubing during detection, then see that can detecting portion pass from the through hole sheet metal component, through after measure gap detecting portion and through hole edge whether in the margin tolerance allowed by taper chi again, thus judge that whether sheet metal component qualified.But such test pin mostly can only realize the detection of location and circular hole, just cannot detect the accuracy of its position for waist-shaped hole (bar hole, slotted eye) rapidly, thus bring inconvenience to the detection of sheet metal component.
Summary of the invention
For prior art above shortcomings, the object of the invention is to the problem that the waist-shaped hole how solved on sheet metal component detects inconvenience, a kind of automobile metal plate work cubing test pin is provided, can detects the waist-shaped hole on sheet metal component fast, and detection speed is fast, and precision is high.
In order to solve the problems of the technologies described above, the technical solution used in the present invention is such: a kind of automobile metal plate work cubing test pin, comprise the portion of the handle be connected successively, detecting portion and targeting part, described portion of the handle, detecting portion and targeting part are the coaxial column structure arranged, and diameter reduces successively, it is characterized in that: be provided with a groove pin in the side of detecting portion, the axis of described groove pin and the axial consistent of detecting portion, its needle portion is fixedly connected with the end face of portion of the handle, and distance between the two ends of distance between the needle point of groove pin and the axial line of detecting portion and the waist-shaped hole of sheet metal component to be measured and its center is equal, when targeting part inserts the detect aperture in cubing, detecting portion can pass sheet metal component to be measured away from one end of portion of the handle, and groove pin can contact with sheet metal component.
Further, the side of described portion of the handle is planar structure.
Further, described targeting part is tapered away from one end of detecting portion.
Compared with prior art, tool of the present invention has the following advantages: structure is simple, and whether the position can either detecting waist-shaped hole dual-side is accurate, and whether the end positions that can detect again waist-shaped hole is accurate, thus makes detection degree of accuracy higher; And in testing process, targeting part inserted the detect aperture of cubing and make detecting portion pass the waist-shaped hole of sheet metal component, so only needing to rotate portion of the handle, the detection at waist-shaped hole two ends can be realized, easy to use, quick.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention;
Fig. 2 is the vertical view of Fig. 1.
Embodiment
Below in conjunction with drawings and Examples, the invention will be further described.
Embodiment: see Fig. 1, Fig. 2, a kind of automobile metal plate work cubing test pin, comprise the portion of the handle 1, detecting portion 2 and the targeting part 3 that are connected successively, described portion of the handle 1, detecting portion 2 and targeting part 3 is the coaxial column structure arranged, and diameter reduces successively.The side of described portion of the handle 1 is planar structure; Be more convenient for like this in testing process, portion of the handle 1 being rotated.Described targeting part 3 is tapered away from one end of detecting portion 2; Thus it is more quick when can make the detect aperture inserted by targeting part 3 in cubing.
A groove pin 4 is provided with in the side of detecting portion 2, the axis of described groove pin 4 and the axial consistent of detecting portion 2, its needle portion is fixedly connected with the end face of portion of the handle 1, and distance between the two ends of distance between the axial line of the needle point of groove pin 4 and detecting portion 2 and the waist-shaped hole of sheet metal component to be measured and its center is equal, when inserting the detect aperture in cubing when targeting part 3, detecting portion 2 can pass sheet metal component to be measured away from one end of portion of the handle 1, and groove pin 4 can contact with sheet metal component.
In testing process, whether the position can being detected waist-shaped hole dual-side by the detecting portion 2 of portion of the handle 1 one end is accurate; Can be detected the position at waist-shaped hole two ends by groove pin 4, thus the accuracy of the center of waist-shaped hole can be detected rapidly, in testing process, only need rotate portion of the handle 1, namely on sheet metal component, mark line is drawn by groove pin 4, thus by the distance between measurement markers line and waist-shaped hole two ends, to judge that whether waist-shaped hole is qualified, easy to detect, quick, and can accuracy of detection be improved.
Finally it should be noted that, above embodiment is only in order to illustrate technical scheme of the present invention but not restriction technologies scheme, those of ordinary skill in the art is to be understood that, those are modified to technical scheme of the present invention or equivalent replacement, and do not depart from aim and the scope of the technical program, all should be encompassed in the middle of right of the present invention.
