Detailed Description

The following describes the present invention in further detail with reference to the accompanying drawings. These embodiments are provided only for illustrating the present invention and are not intended to limit the present invention.

In the description of the present invention, it should be noted that the terms "middle part", "inside", "outside", and the like indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings, which is only for convenience of description and simplification of the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed in a specific orientation, and be operated, and thus, should not be construed as limiting the present invention. Furthermore, the terms "first" and "second" are used for descriptive purposes only and are not to be construed as indicating or implying relative importance.

In the description of the present invention, it is to be noted that, unless otherwise explicitly specified or limited, the term "connected" is to be interpreted broadly, for example, as a fixed connection, a detachable connection, or an integral connection; may be directly connected or indirectly connected through an intermediate. The specific meaning of the above terms in the present invention can be understood according to specific situations by those skilled in the art.

As shown in FIG. 1 and FIG. 2, the utility model provides an inspection device for examining the internal and external diameters of thrust plate 3, including the external diameter no-go gage 1 that is used for examining the external diameter of thrust plate 3 and the internal diameter no-go gage 2 that is used for examining the internal diameter of thrust plate 3, external diameter no-go gage 1 is as shown in FIG. 3, including external diameter no-go gage 11 and external diameter no-go gage 12. The outer diameter gauge 11 is a cylinder, in which a first measuring hole 111 is formed along the axial direction. The outer diameter no-go gauge 12 is an annular baffle plate, is coaxially arranged in the first measuring hole 111, and is internally provided with a second measuring hole 121 which is coaxial with the first measuring hole 111, and the second measuring hole 121 is communicated with the first measuring hole 111. The diameter of the first measurement hole 111 is greater than the diameter of the second measurement hole 121 because the diameter of the first measurement hole 111 is the upper limit value of the tolerance of the outer diameter of the push piece 3 and the diameter of the second measurement hole 121 is the lower limit value of the tolerance of the outer diameter of the push piece 3.

When the thrust plate 3 is used, the thrust plate 3 is pushed to the outer diameter stop gauge 1, and if the outer arc surface 31 of the thrust plate 3 can penetrate into the first measuring hole 111 but cannot penetrate into the second measuring hole 121, the outer diameter of the thrust plate 3 is judged to be qualified; if the extrados surface 31 of the thrust plate 3 cannot penetrate into the first measurement hole 111, or can penetrate into both the first measurement hole 111 and the second measurement hole 121, the outer diameter of the thrust plate 3 is determined to be unqualified. Preferably, the first measuring hole 111 is a through hole, and the second measuring hole 121 is disposed in the middle of the first measuring hole 111, so that after the arrangement, the two thrust plates 3 can be pushed into the first measuring hole 111 at the same time, and the detection efficiency is improved.

As shown in fig. 1, 2 and 4, the inner diameter no-go gauge 2 includes an inner diameter no-go gauge 21 and an inner diameter no-go gauge 22 both having a cylindrical shape, and the inner diameter no-go gauge 22 is connected to an end portion of the inner diameter no-go gauge 21 and is disposed coaxially with the inner diameter no-go gauge 21. Since the outer diameter of the inner diameter gauge 21 is the lower limit of the tolerance of the inner diameter of the push piece 3 and the outer diameter of the inner diameter gauge 22 is the upper limit of the tolerance of the inner diameter of the push piece 3, the outer diameter of the inner diameter gauge 22 is larger than the outer diameter of the inner diameter gauge 21.

When the thrust plate is used, the thrust plate 3 with qualified outer diameter is placed in the first measuring hole 111, then the inner diameter go gauge 21 of the inner diameter go gauge 2 is pushed to the thrust plate 3, and if the inner diameter go gauge 21 can pass through the intrados 32 of the thrust plate 3 but the inner diameter no gauge 22 cannot pass through, the inner diameter of the thrust plate 3 is judged to be qualified; if the internal diameter gauge 21 cannot pass through the intrados 32 of the thrust plate 3 or the internal diameter gauge 22 can pass through the intrados 32 of the thrust plate 3, the internal diameter of the thrust plate 3 is judged to be unqualified. Preferably, one end of the inner diameter no-go gauge 22 is connected with the inner diameter go gauge 21, and the other end is provided with a handle 23, so that an operator can conveniently hold the inner diameter no-go gauge by hand during inspection.

To sum up, the utility model discloses an useful part lies in, simple structure, and the external diameter through accurate processing ends to lead to rule and internal diameter end to lead to rule and cooperate, can carry out accurate inspection to the inside and outside diameter of thrust piece, and application method is simple, has improved inspection and production efficiency greatly.
