Abstract

Provided is a detecting pin characterized by comprising a guiding portion, a hole detecting portion, and a surface detecting portion. The detecting portion of the detecting pin is formed by the hole detecting portion and the surface detecting portion. The detecting portion and the guiding portion are coaxial. The detecting surface of the surface detecting portion is vertical to the guiding portion. The operating dimension of the hole detecting portion is more than or equal to that of the guiding portion. The operating dimension of the surface detecting portion is more than the diameter of a hole, required to be detected, on a sheet metal component. The detecting pin has superiority that the detecting pin is used for detecting surfaces and holes and is low in cost so as to greatly decrease production cost.

Description

A kind of test pin

(1) technical field:

The utility model relates to the detection of automobile metal plate work hole and critical surfaces, especially a kind of test pin.

(2) technical background:

Some critical surfaces of automobile metal plate work needs to detect, and on face, porose also need detected simultaneously, but because face is too little, or too far away apart from body edges, cause this face detection difficult.

(3) utility model content:

The purpose of this utility model is a kind of test pin of invention, and it can solve the deficiencies in the prior art, and it can detect place, hole face in detecting hole, detects thereby substituted with detecting clamp, has reduced cost.

The technical solution of the utility model: a kind of test pin, is characterized in that it is made up of targeting part, Ji Mian test section, test section, hole; He Mian test section, test section, described hole forms test pin test section, and test section is coaxial with targeting part; The detection faces of described test section is vertical with targeting part; Test section, described hole working size is more than or equal to targeting part working size; Described test section working size is greater than the bore dia that needs detection on sheet metal component.

Described test pin face test section is connected with handle.

Described test pin test section and targeting part right alignment Φ 0.02; The detection faces of described test section and targeting part verticality 0.02; More than described test section working size is greater than the bore dia 4mm that needs to detect on sheet metal component.

On described targeting part, cover has band shoulder to overlap, and band shoulder cover shoulder diameter is greater than the bore dia that needs detection on sheet metal component.

Described targeting part and band shoulder cover gap tolerance on fit H7/g6, more than the diameter of band shoulder cover shoulder is greater than the bore dia 4mm that needs to detect on sheet metal component.

The course of work of the present utility model: install after plates of automobile, pin is inserted in corresponding hole; The size that detects hole is met tolerance by whether the test section, hole of pin, and whether face test section meets tolerance by tool detection faces such as sharp chis.

Superiority of the present utility model: the utility model provides the device in a kind of detection faces and hole, this apparatus cost is cheap, has greatly saved manufacturing cost.

Wherein, 1 is test pin, and 1-1 is targeting part, 1-2 is test section, hole, and 1-3 is face test section, and 1-4 is handle, 2 is sheet metal component, and 3 is band shoulder cover, and 4 for needing the hole of detection on sheet metal component, A is face test section working size, and B is test section, hole working size, and C is targeting part working size, D is face test section work theory size, d is the diameter of band shoulder cover shoulder, and t is the gap width of part and cubing, and T is the detection faces of face test section and the theoretical value of part.

(5) embodiment:

Embodiment: a kind of test pin (seeing Fig. 1, Fig. 4), is characterized in that it is made up of targeting part 1-1,1-2Ji Mian test section, test section, hole 1-3; Test section, described hole 1-2He Mian test section 1-3 forms test pin test section, and test section is coaxial with targeting part 1-1; The detection faces of described test section 1-3 is vertical with targeting part 1-1; Test section, described hole 1-2 working size B is more than or equal to targeting part 1-1 working size C; Described test section 1-3 working size A is greater than the diameter that needs the hole 4 of detecting on sheet metal component 2.

1 test section 1-3 outside of described test pin is connected with handle 1-4.(seeing Fig. 1, Fig. 4)

Described test pin 1 test section and targeting part 1-1 right alignment Φ 0.02; The detection faces of described test section 1-3 and targeting part 1-1 verticality 0.02; More than described test section 1-3 working size A is greater than the diameter 4mm that needs the hole 4 of detecting on sheet metal component 2.

The upper cover of described test pin 1 targeting part 1-1 has band shoulder to overlap 3, and band shoulder cover shoulder diameter d is greater than hole 4 diameters that need detection on sheet metal component 2.(seeing Fig. 2, Fig. 3, Fig. 4)

Described test pin 1 targeting part 1-1 and band shoulder cover 3 clearance fit tolerance H7/g6, more than the diameter d of band shoulder cover shoulder is greater than the hole 4 diameter 4mm that need to detect on sheet metal component 2.

The course of work of the present embodiment: install after plates of automobile, test pin is inserted in corresponding hole; The size that detects hole is met tolerance by whether the test section, hole of test pin, and whether face test section meets tolerance by tool detection faces such as sharp chis.
