In like manner, as wanted detect aperture depth (calling in the following text at " detection position ") internal diameter whether qualified, be difficult to equally realize by conventional sense means.
As shown in Figure 3, arrange verify not-go-end 21 and verify go side 22 respectively at the two ends of handle 3, verify not-go-end 21 and verify go side 22 are diameter and change trickle cylindrical mechanism tradition verify go-no go gauge 2, are closed structure.After easy after patchhole, the interference at the non-detection position of hole wall, can not judge the overproof position of part intuitively, lose the meaning that go-no go gauge detects fast, even to having detected misleading effect.
Summary of the invention
Open structure is led to, the verify go-no go gauge of not-go-end to the object of this invention is to provide whether qualified the having of certain position size in a kind of detect aperture, to solve the problem that conventional verify go-no go gauge is difficult to realize this detection.
For reaching foregoing invention object, the technical solution adopted in the present invention is: provide a kind of verify go-no go gauge, comprise handle and the verify not-go-end and the verify go side that are separately positioned on handle two ends, described verify not-go-end and verify go side are open structure, and this open structure is disc-shaped structure; Verify not-go-end is connected with handle two ends respectively by connecting link with verify go side, and the length of two connecting links is equal to the degree of depth at the detection position needing the hole detected.
Described connecting link is the connecting link of length adjustment.
Further, described connecting link is adjusting bolt or lockable contracting bar.
The thickness of described disc-shaped structure is 3-10mm.
Further, the thickness of described disc-shaped structure is 5mm.
In sum, this verify go-no go gauge has that open structure is logical, not-go-end, achieves the accurate detection to hole certain position size.And materials and conventional verify go-no go gauge are almost, and processing cost can not increase, therefore cost can not increase.

Embodiment
Below in conjunction with accompanying drawing, the specific embodiment of the present invention is described in detail.
As shown in Figure 3, this inspection pin go-no go gauge 1, comprise handle 3 and be separately positioned on the inspection pin not-go-end 11 at handle 3 two ends and examine pin go side 12, examining pin not-go-end 11 and examining pin go side 12 is open structure, and this open structure is the schistose texture of central aperture.
Use for convenience and make, the schistose texture of described central aperture is cirque structure.Certainly also can make as other shapes such as hexagon, quadrilateral, only have central aperture.
The thickness of the schistose texture of described central aperture is 3-10mm.More preferably, the thickness of the schistose texture of described central aperture is 5mm.
As shown in Figure 6, according to drawing requirement, the size of test pin A distance root 2mm place A1, therefore first on pin A, overlap the thick pad B of a 2mm, then go to detect by this inspection pin go-no go gauge 1.When inspection pin go side 12 can be pasted with pad B zero smoothly, when inspection pin not-go-end 11 and pad B have some gaps, this sell A be qualified.If inspection pin go side 12 and pad B can not zero to paste, then prove that this sells A oversize, defective; If inspection pin not-go-end 11 also pastes with pad zero, then prove that this pin A is undersized, defective.
As shown in Figure 4, this verify go-no go gauge 2, comprise handle 3 and the verify not-go-end 21 and the verify go side 22 that are separately positioned on handle 3 two ends, described verify not-go-end 21 and verify go side 22 are open structure, and this open structure is disc-shaped structure; Verify not-go-end 21 is connected with handle 3 two ends respectively by connecting link 23 with verify go side 22, and the length of two connecting links 23 is equal to the degree of depth at the detection position needing the hole detected
The thickness of described disc-shaped structure is 3-10mm.Preferably, the thickness of described disc-shaped structure is 5mm.
