[0028] Please refer to Figure 2 and Figure 3 The present embodiment discloses a sealing area gauge, including a gauge body 100. The interior of the gauge body 100 is provided with a sleeve cavity 110 adapted to a target workpiece 10. In this embodiment, a water nozzle of an engine casing is used as the target workpiece 10. The gauge body 100 is provided with an opening 120 at a first end of the sleeve cavity 110. The opening 120 is communicated with the sleeve cavity 110 so that the gauge body 100 can be sleeved on the target workpiece 10. The gauge body 100 is provided with a positioning portion 130 at a second end of the sleeve cavity 110. The positioning portion 130 is used to abut and position with an end portion of the target workpiece 10, so as to locate the area to be inspected through the end portion of the target workpiece 10. A detection window 140 is provided on a side wall of the gauge body 100. The detection window 140 is communicated with the sleeve cavity 110 and defines the area to be inspected of the target workpiece 10. The positioning portion 130 may be the bottom wall of the sleeve cavity 110 , or an annular positioning protrusion disposed inside the sleeve cavity 110 , or a positioning protrusion disposed at the bottom of the sleeve cavity 110 , such as a positioning column or a bump.
[0029] When in use, the sleeve cavity 110 of the inspection fixture body 100 is sleeved with the target workpiece 10, and the target workpiece 10 is abutted and positioned by the positioning portion 130, so that the position of the inspection window 140 is in the area to be inspected of the target workpiece 10. The area to be inspected of the target workpiece 10 can be visually inspected through the inspection window 140, which can facilitate defect detection of the area on the target workpiece 10 for installing the sealing ring.
[0030] To facilitate defect detection, one or more inspection windows 140 are provided, with the plurality of inspection windows 140 circumferentially distributed along the sidewall of the inspection body. When there is only one inspection window 140, it is necessary to ensure the connection strength of the inspection fixture body 100 while maximizing the coverage of the inspection window 140 to facilitate visual inspection of the target workpiece 10's inspection area.
[0031] Please refer to Figure 2 、 Figure 3 and Figure 4 The inspection tool body 100 is provided with a plurality of connecting parts 150, and a thinning area 151 is provided on the inner side of the connecting part 150 to reduce the thickness of the connecting part 150. When the inspection tool body 100 is sleeved on the target workpiece 10, the thinning area 151 can be used to avoid being blocked by the connecting part 150, thereby reducing the blind spot of the field of view, which is more conducive to visual inspection of the area to be inspected of the target workpiece 10. The plurality of connecting parts 150 and the plurality of inspection windows 140 are distributed at intervals. For example, the inspection tool body 100 is provided with four connecting parts 150, and the number of inspection windows 140 is also four. The four connecting parts 150 and the four inspection windows 140 are distributed at intervals and are located on the same circumference. During inspection, the operator puts the inspection fixture body 100 on the target workpiece 10, and observes whether there are casting defects in the area to be inspected on the target workpiece 10 through the four inspection windows 140, and rotates the inspection body to switch the inspection window 140 to the inspection blind area blocked by the connection part 150, thereby achieving a comprehensive inspection of the area to be inspected.
[0032] Please refer to Figure 2 and Figure 4 A chamfered surface 141 is provided on the side wall of the inspection fixture body 100 and at the edge of the inspection window 140. The chamfered surface 141 can reduce the thickness of the side wall of the inspection fixture body 100 and increase the window size of the inspection window 140, thereby obtaining a better observation field of view and reducing blind spots, which is conducive to improving the convenience and reliability of visual inspection.
[0033] Please refer to Figure 2 and Figure 3When in use, the opening 120 of the gauge body 100 needs to be sleeved on the target workpiece 10. In order to ensure that the gauge body 100 and the target workpiece 10 can be tightly sleeved and avoid positioning errors caused by the sleeve gap, the gauge body 100 is provided with a contour surface 121 adapted to the target workpiece 10 at the opening 120. The contour surface 121 is adapted to the outer contour of the target workpiece 10. For example, if the position where the target workpiece 10 contacts the opening 120 of the gauge body 100 is a frustum structure, then the contour surface 121 is a trumpet-shaped inclined surface adapted to the side wall of the frustum structure.
[0034] The contoured surface 121 is provided with a guide portion 122, which can play a certain guiding role during the insertion of the gauge body 100 and the target workpiece 10, thereby facilitating the insertion of the gauge body 100 and the target workpiece 10. For example, the guide portion 122 is a rounded structure provided at the edge of the opening 120.
[0035] Please refer to Figure 3 The gauge body 100 is provided with an extension portion 160 at the second end of the sleeve cavity 110. The extension portion 160 can be a cylindrical structure, a rectangular parallelepiped structure, a prismatic structure, etc. The extension portion 160 is conducive to extending the size of the gauge body 100, making it easier for the operator to grasp and use it.
[0036] In the above application example, the gauge body 100 is an integrated structure, which is easy to manufacture. The integrated structure can make the gauge body 100 have good integrity, does not require assembly, and is easy to use.
[0037] In the above application example, the gauge body 100 is a soft rubber gauge, for example, a gauge made of materials such as silicone or soft plastic, which has a soft texture and avoids scratching the target workpiece 10 during the process of being fitted with the target workpiece 10, thereby ensuring the safety of the inspection.
[0038] The embodiments of the present invention are described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Various changes can be made within the scope of knowledge possessed by ordinary technicians in the relevant technical field without departing from the purpose of the present invention.
