[0024] The present application will be described in detail below in conjunction with embodiments, but the present application is not limited to these embodiments.

[0025] Referring to Figures 1-5 , a CA-3 coupler head internal detection sample plate, characterized in that, comprising:

[0026] A base plate 1, a detection element is arranged on the face of the base plate 1, the detection element comprises a gauge pointer 2, the gauge pointer 2 is rotationally connected with the base plate 1, the mounting end of the gauge pointer 2 is located on one side of the base plate 1, the pointer end of the gauge pointer 2 points to the other side of the base plate 1, the side of the base plate 1 pointed by the pointer end of the gauge pointer 2 is provided with a detection indication structure, the position of the detection indication structure corresponds to the mounting end of the gauge pointer 2, for indicating the rotational position change of the gauge pointer 2;

[0027] The face of the base plate 1 is also provided with a lock bracket hanging shaft positioning structure, the lock bracket hanging shaft positioning structure is used for pre-positioning by the lock bracket hanging shaft during detection, and whether the pre-positioning of the lock bracket hanging shaft drives the rotational position of the gauge pointer 2 to change, realizing the detection of the installation of the lock bracket hanging shaft.

[0028] The lock bracket hanging shaft positioning structure comprises a lock bracket hanging shaft upper support column 4 arranged on the base plate 1 and a lock bracket hanging shaft side support column 6 arranged on the gauge pointer 2;

[0029] The lock bracket hanging shaft upper support column 4 is used for abutting against the upper end of the coupler lock bracket hanging shaft, the mounting end side of the gauge pointer 2 is provided with an extension plate 5, the lock bracket hanging shaft side support column 6 is located on the extension plate 5, and the lock bracket hanging shaft side support column 6 is used for abutting against the side of the coupler lock bracket hanging shaft.

[0030] The back of the base plate 1 is provided with a support positioning element, the support positioning element is used for making the detection sample plate fit the side of the coupler hook cavity.

[0031] The detection indicating structure is a notch 3 arranged on the bottom plate, the position of the notch 3 corresponds to the mounting end of the gauge pointer 2, and is used for indicating the rotation position change of the gauge pointer 2.

[0032] Specifically, the detection sample plate is composed of a bottom plate, a gauge support, a gauge support, an upper locking bracket hanging shaft support, a locking bracket hanging shaft side support, a gauge pointer, and a support positioning piece. The gauge pointer is connected with the bottom plate through a pin shaft and can swing. The upper locking bracket hanging shaft support is fixed on the bottom plate. The gauge support and the gauge support are fixed on the bottom plate. The back of the bottom plate is fixed with the positioning piece.

[0033] As shown in Figures 3-5 When the sample plate is used, first, the sample plate is inserted into the inner cavity of the coupler hook head. When installing, the gauge support should be attached to the engagement surface of the coupler, the positioning support should be attached to the side surface of the coupler hook cavity, and the upper locking bracket hanging shaft support should be close to the upper end of the locking bracket hanging shaft. After the above installation is completed, the gauge pointer of the sample plate is pushed until the locking bracket hanging shaft side support is close to the side of the locking bracket hanging shaft. At this time, it is observed whether the position of the pointer tip is between the notches on the gauge. If the pointer tip is between the notches, it means that the position of the locking bracket hanging shaft is qualified. If it exceeds the notch, it means that the position of the locking bracket hanging shaft is unqualified.

[0034] It is worth mentioning that the sample plate is simple to make, low in cost, light in weight, easy to carry, and easy to maintain. At the same time, product inspection is very convenient. After installation, only the position of the gauge pointer needs to be observed to determine whether the product size is qualified. Further, the product inspection efficiency is improved, the operation is simple, and it is particularly suitable for mass production.

[0035] The bottom plate 1 includes a fixed part and a detection part connected with each other. The detection part is located on one side of the fixed part. Gauge supports 7 are arranged at both ends of the face of the fixed part. The gauge supports 7 are attached to the engagement surface of the coupler.

[0036] The mounting end of the gauge pointer 2 and the upper locking bracket hanging shaft support 4 are arranged on the detection end face. The pointer end of the gauge pointer 2 points to the fixed part.

[0037] The notch 3 is arranged on the side of the fixed part away from the detection part.

[0038] Specifically, when the upper locking bracket hanging shaft support is close to the locking bracket hanging shaft, if the outer dimension of the locking bracket hanging shaft is too large, when the locking bracket hanging shaft side support is close to the locking bracket hanging shaft, the position of the needle tip will be deflected downward by swinging of the gauge pointer, exceeding the measurement notch on the bottom plate. At this time, it can be known that the outer dimension of the locking bracket hanging shaft is too large and unqualified.

[0039] If the outer dimension of the lock bracket hanging shaft is too small, when the lock bracket hanging shaft side support is close to the lock bracket hanging shaft, the needle tip position will be deflected upward by the swing of the gauge pointer, exceeding the measuring gap on the bottom plate, at which time it can be known that the outer dimension of the lock bracket hanging shaft is too small, and unqualified;

[0040] If the position dimension of the lock bracket hanging shaft is right, when the lock bracket hanging shaft side support is close to the lock bracket hanging shaft, the needle tip position will be deflected upward by the swing of the gauge pointer, exceeding the measuring gap on the bottom plate, at which time it can be known that the position dimension of the lock bracket hanging shaft is right, and unqualified;

[0041] If the position dimension of the lock bracket hanging shaft is left, when the lock bracket hanging shaft side support is close to the lock bracket hanging shaft, the needle tip position will be deflected downward by the swing of the gauge pointer, exceeding the measuring gap on the bottom plate, at which time it can be known that the position dimension of the lock bracket hanging shaft is left, and unqualified;

[0042] In summary, only when the outer dimension and the position dimension of the lock bracket hanging shaft are within the tolerance range, can the product pass the detection of the sample plate, at which time the product is qualified.

[0043] It is worth mentioning that the total length of the gauge pointer (the straight line length from the gauge pointer tip to the other end of the gauge pointer) is 155 mm, the dimension from the gauge pointer mounting end shaft center to the other end of the gauge pointer is 18 mm, the dimension from the mounting position of the lock bracket hanging shaft side support to the other end of the gauge pointer is 28 mm, and the dimension from the gauge pointer mounting end shaft center to the edge of the extension plate is 73 mm.

[0044] The support positioning member includes a plurality of positioning supports 8, which are distributed on the side of the bottom plate, and the positioning supports 8 are attached to the side of the coupler hook cavity.

[0045] Specifically, the positioning supports are three in number, ensuring the accuracy and stability of the position during the measurement.

[0046] The gauge support 7 is arranged at an angle with the attached end of the coupler engagement surface and the fixed part.

[0047] Specifically, the angle is an obtuse angle, in order to be attached to the coupler engagement surface.

[0048] The above is only a few embodiments of the present application, and does not limit the present application in any form. Although the preferred embodiments are disclosed above, the present application is not limited thereto. Any person skilled in the art can make some changes or modifications to the above disclosed technical content without departing from the scope of the technical solution of the present application, which are equivalent to equivalent embodiments, and belong to the scope of the technical solution.
