Detailed Implementation

[0019] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0020] The specific implementation of this utility model will be described in detail below with reference to specific embodiments.

[0021] like Figure 1-3 As shown, the engine lower guard plate inspection tool includes a base 1, on which a contoured seat is provided to support the engine lower guard plate. The contoured seat is adapted to the shape of the lower guard plate to ensure the support of the lower guard plate. The base 1 is provided with a fixing component for fixing the engine lower guard plate. The fixing component is used to fix the lower guard plate on the contoured seat.

[0022] In use, the lower guard plate is placed on the contour base and fixed by the fixing components on the base 1, which facilitates the stable clamping of the lower guard plate on the base 1. This makes it easier to inspect the shape of the lower guard plate using inspection tools, resulting in more accurate inspection results and greater practicality.

[0023] Specifically, the contouring seat includes a surrounding seat 2 and a lifting seat 3. The surrounding seat 2 is connected to the base 1 by bolts. The base 1 is provided with a side seat 4, which is connected to the lifting seat 3. The contouring seat composed of the surrounding seat 2 and the lifting seat 3 provides support for the lower guard plate. The lifting seat 3 is raised at one end of the contouring seat through the side seat 4, which facilitates the adaptation to the shape of the lower guard plate and thus achieves stable placement of the lower slide plate. Specifically, the side seat 4 is connected to the base 1 by bolts and to the lifting seat 3 by bolts. The side seat 4 has an L-shaped cross section and is also provided with reinforcing ribs to increase its strength. In this embodiment, there are three side seats 4.

[0024] The fixing component includes a positioning seat 5 and a threaded pin 6. The positioning seat 5 is connected to the base 1 by bolts, and the threaded pin 6 is connected to the base 1. The positioning seat 5 is provided with a threaded hole 501 that mates with the threaded pin 6. When the lower guard plate falls on the contour seat, the threaded hole 501 on the positioning seat 5 is aligned with the mounting hole on the lower guard plate. At this time, the threaded pin 6 is passed through the mounting hole and mates with the threaded hole 501 on the positioning seat 5, thereby realizing the fixing of the lower guard plate. In this embodiment, there are nine positioning seats 5, which are arranged inside the contour seat, and the base 1 is provided with nine threaded pins 6.

[0025] An auxiliary seat 9 is provided on the base 1. The auxiliary seat 9 is connected to the threaded pin 6 through an elastic rope 10. The threaded pin 6 is fixed on the base 1 by the setting of the elastic rope 10 and the auxiliary seat 9. Specifically, the auxiliary seat 9 is connected to the base 1 by bolts.

[0026] The threaded pin 6 is provided with a threaded post 7 that is threaded to the positioning seat 5. The threaded post 7 passes through the mounting hole and connects to the positioning seat 5. The threaded pin 6 is provided with a limiting block 8, so that the threaded post 7 moves down the positioning seat 5 to contact the lower guard plate, thereby achieving stable clamping of the lower guard plate.

[0027] A fixed seat 11 is provided on the base 1, and a fixed block 12 is provided on the fixed seat 11. A handle 13 is hinged to the fixed block 12, and a swing arm 14 is provided on the fixed block 12. The swing arm 14 is fixedly connected to the handle 13. A detection block 15 is provided at the end of the swing arm 14, and a detection hole 16 is provided on the detection block 15. Rotating the handle 13 causes the swing arm 14 to move on the fixed block 12 until the detection block 15 on the swing arm 14 is suspended above the lower guard plate. At this time, the detector instrument performs detection work on the surface of the lower guard plate through the detection hole 16.

[0028] The fixed seat 11 is positioned opposite to the lifting seat 3, thereby controlling the position of the detection hole 6 on the detection block 15.

[0029] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
