DETAILED DESCRIPTION

A mounting frame 2 and a translucent drawing 332 are arranged between the parallel light source plate 11 and the visual camera 12, and the mounting frame 2 is used to install the automobile chassis to be inspected, and the translucent drawing 332 is printed with a standard through-hole profile of the automobile chassis. The base 1 is fixedly provided with a slide rail 14 along the length direction, and the mounting frame 2 is slidably arranged on the slide rail 14. The mounting frame 2 is close to and directly opposite to the parallel light source plate 11, and the translucent drawing 332 is directly opposite to the mounting frame 2, and the visual camera 12 shines on the side of the translucent drawing 332 away from the mounting frame 2. A detection table 13 is fixedly arranged on the base 1, and a control screen 131 is fixedly arranged on the detection table 13. A processor is arranged in the detection table 13, and the visual camera 12 and the control screen 131 are both connected to the processor.
[0032] Reference Figure 1During the inspection, the mounting frame 2 is slid out from between the parallel light source plate 11 and the light-transmitting drawing 332, and the automobile chassis is fixed on the mounting frame 2. The parallel light source plate 11 is started, and the parallel light source plate 11 emits parallel light, and the light passes through the punched through hole of the chassis and reflects the light area on the light-transmitting drawing 332. The visual camera 12 records the image on the light-transmitting drawing 332 and transmits the image to the processor for analysis. By comparing the light area with the standard through hole contour, the processor determines whether the filling degree or overflow degree of the light area within the contour is qualified. The detection results are displayed on the control screen 131, thereby realizing efficient detection of the punched through holes. This facilitates the detection of the punched through holes on the automobile chassis, reduces the labor intensity, and improves the detection efficiency.
[0033] In order to fix the automobile chassis to be tested on the mounting frame 2, refer to Figure 1 and Figure 2 The mounting frame 2 includes a slider 21, a support rod 22, a first clamping plate 23, a second clamping plate 24 and a locking member 25. The slider 21 is slidably arranged in a group in the slide rail 14, the support rod 22 is vertically and fixedly arranged on the slider 21, and five groups of first clamping plates 23 and second clamping plates 24 are arranged in pairs on each support rod 22. The first clamping plate 23 and the second clamping plate 24 are both rotatably connected to the support rod 22, and the locking member 25 can drive the first clamping plate 23 and the second clamping plate 24 to clamp each other. The inner surfaces of the first clamping plate 23 and the second clamping plate 24 are fixedly arranged with rubber pads 254, and the rubber pads 254 are in contact with the chassis of the vehicle. The locking member 25 includes a nut 251 , a deflection frame 252 , and a bolt 253 . The nut 251 is rotatably disposed on the second clamping plate 24 , the deflection frame 252 is rotatably disposed on the first clamping plate 23 , the bolt 253 is rotatably disposed in the deflection frame 252 , and the bolt 253 can be threadedly engaged with the nut 251 .
[0034] Reference Figure 1 and Figure 2 When it is necessary to fix the automobile chassis to be inspected on the mounting frame 2, the two support rods 22 are first slid away from each other and the automobile chassis is placed between the two support rods 22. Then the support rods 22 are controlled to approach the two sides of the automobile chassis, the first clamping plate 23 and the second clamping plate 24 are clamped to the side of the automobile chassis, and then the nut 251 is controlled to face the deflection frame 252, the bolt 253 is rotated and the bolt 253 is screwed into the nut 251, and the side of the automobile chassis is clamped and fixed by the first clamping plate 23 and the second clamping plate 24. If a through hole is opened on the automobile chassis at the clamping position of the first clamping plate 23 and the second clamping plate 24, the first clamping plate 23 and the second clamping plate 24 can be rotated to the side of the support rod 22 away from the automobile chassis, so as to avoid the first clamping plate 23 and the second clamping plate 24 blocking the through hole as much as possible.
[0035] In order to avoid the interference of the measurement results caused by the error of installing the car chassis, refer to Figure 1 and Figure 3The base 1 is fixedly provided with a support frame 3 along the length direction, and a vertical adjustment cylinder 31 is fixedly provided on the side wall of the support frame 3.

The transparent drawing 332 is inserted into the slot 331 to facilitate the replacement of the transparent drawing 332. When the automobile chassis is installed on the fixed frame, it is difficult to ensure that the automobile chassis is completely opposite to the transparent drawing 332, that is, the relative position of the automobile chassis and the transparent drawing 332 is offset as a whole, and the light area on the transparent drawing 332 is relatively offset as a whole with respect to the standard through-hole contour. At this time, the overall height position of the transparent plate 33 can be adjusted by the vertical adjustment cylinder 31, and the overall horizontal position of the transparent plate 33 can be adjusted by the horizontal adjustment cylinder 32, so that the light area and the standard through-hole contour are overlapped as much as possible, thereby avoiding the interference of the error of installing the automobile chassis on the measurement result as much as possible.

Then, slide the mounting frame 2 out through the slide rail 14, fix the automobile chassis on the mounting frame 2 and then slide it back to its original position. Start the detection program, the parallel light source plate 11 emits light, the light passes through the punched through-hole on the chassis, and reflects the light area on the translucent drawing 332, the visual camera 12 captures the light area image and the standard through-hole profile information, and the processor analyzes the filling or overflow degree of the light area within the standard through-hole profile. Finally, the detection results are intuitively displayed through the control screen 131.
[0038] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto.
