Detailed Description
In order to make the technical problems, technical solutions and advantages to be solved by the present invention clearer, the following detailed description will be given with reference to the accompanying drawings and specific embodiments.
As shown in fig. 1-2, an embodiment of the present invention provides a special inspection tool for inner diameter, which includes a lower limit inspection plate 1 and an upper limit inspection plate 3, wherein the lower limit inspection plate 1 is adapted to a diameter lower limit of a workpiece to be inspected, the upper limit inspection plate 3 is adapted to a diameter upper limit of the workpiece to be inspected, the lower limit inspection plate 1 is arranged in parallel with the upper limit inspection plate 3, and a connecting cylinder 2 is arranged between the lower limit inspection plate 1 and the upper limit inspection plate 3; the central axes of the lower limit inspection plate 1 and the upper limit inspection plate 3 are overlapped, and the diameter of the lower limit inspection plate 1 is smaller than that of the upper limit inspection plate 3; the special inner diameter detection tool further comprises a handle 4, so that the special inner diameter detection tool can be taken conveniently, and the handle 4 penetrates through the upper limit detection disc 3 and then is connected with the lower limit detection disc 1.
Specifically, the special inner diameter gauge is of an axisymmetric structure, and the lower limit inspection plate 1 and the upper limit inspection plate 3 are both of circular flat plate-shaped structures.
The utility model discloses an among the concrete embodiment, it is optional, be the circular arc transition between the lower terminal surface of lower limit inspection disk 1 and the side, be the circular arc transition between the lower terminal surface of upper limit inspection disk 3 and the side to in when examining will the special utensil of examining of internal diameter inserts the inboard of examining the inspection work piece.
As shown in fig. 1, the handle 4 is a cylindrical structure, a through hole adapted to the handle 4 is formed in the center of the upper limit inspection plate 3, and the handle 4 is located in the center of the lower limit inspection plate 1 and is vertically connected to the lower limit inspection plate 1.
In addition, one end of the handle 4 is connected with the lower limit inspection plate 1, and the other end is provided with a chamfer.
In this embodiment, the connecting cylinder 2 is provided coaxially with the handle 4, and therefore, the connecting cylinder 2 is also coaxial with the lower limit checking plate 1 and the upper limit checking plate 3.
Specifically, the connecting cylinder 2 is of a cylindrical structure.
The utility model provides an utensil use as follows is examined in internal diameter special use:
as shown in fig. 2, when the inner diameter of a workpiece needs to be inspected, the lower limit inspection plate 1 of the inner diameter special inspection tool can be inserted into the inner side of the workpiece to be inspected through the hand-held handle 4, and if the upper limit inspection plate 3 of the inner diameter special inspection tool cannot pass through the inner hole of the workpiece to be inspected, the workpiece is judged to be qualified.
