Therefore, the terms describing the positional relationship in the drawings are only used for illustrative purposes and cannot be understood as limitations on this patent. For ordinary technicians in this field, the specific meanings of the above terms can be understood according to specific circumstances.

[0024] The technical solution of the present invention is further described in detail below through specific embodiments and in conjunction with the accompanying drawings:

[0025] Example 1

[0026] like Figure 1 As shown, a detection device for automobile chassis parts production includes a base 1, a workbench 2 for placing the automobile chassis, a top plate 3, a positioning plate 4 and a detection assembly 5. The workbench 2 is arranged on the upper surface of the base 1, and the top plate 3 is arranged above the base 1 through a support column 6. A driving member 7 for driving the positioning plate 4 to rise and fall is arranged on the top plate 3. The driving member 7 is connected to the positioning plate 4, and the detection assembly 5 is installed on the positioning plate 4. The workbench 2 is fixed on the base 1, and the top plate 3 is erected above the workbench 2 by the support column 6. The detection assembly 5 is installed on the top plate 3, thereby forming a space for placing automobile chassis parts between the detection assembly 5 and the workbench 2. When the automobile chassis parts need to be detected, the automobile chassis parts only need to be placed on the workbench 2, and then the driving member 6 is started. The positioning plate 4 is installed at the telescopic end of the driving member 7. After the driving member 7 is started, the positioning plate 4 is driven to move downward. The detection assembly 5 is installed on the positioning plate 4, thereby, the detection assembly 5 extends into the automobile chassis parts as the positioning plate 4 descends, and then the detection begins. When the detection is completed, the driving member 7 drives the detection assembly 5 to move upward and extend it out of the automobile chassis, so as to facilitate the replacement of the automobile chassis parts placed on the workbench.

[0027] like Figure 1 , 2As shown, the detection assembly 5 includes a motor 51, a fixing plate 52, a first telescopic rod 53 and a detection plate 54. The motor 51 is mounted on the positioning plate 4, the fixing plate 52 is mounted on the rotating shaft of the motor 51, and the first telescopic rods 53 are arranged on two opposite sides of the fixing plate 52. The telescopic ends of each first telescopic rod 53 are mounted with a detection plate 54 in the vertical direction. The length of the first telescopic rod 53 is adjustable and can be adjusted to the same radius as the automobile chassis parts to match automobile chassis parts of different specifications. The detection plate 54 is installed at one end of the first telescopic rod 53 away from the fixing plate 52. The rotating shaft of the motor 51 is located directly above the center of the automobile chassis parts. When detecting whether the automobile chassis parts are qualified, after fixing the automobile chassis parts, the detection assembly 5 is extended into the automobile chassis parts, the first telescopic member 53 is adjusted to match the automobile chassis parts, and then the motor 51 is started. The motor 51 drives the fixing plate 52 to rotate, and then drives the first telescopic rod 53 to rotate. After the first telescopic rod 53 rotates one circle, if the detection plate 54 does not collide with the automobile chassis parts, it means that the size of the automobile chassis parts meets the requirements.

[0028] like Figure 2 , 3 As shown, the detection assembly also includes a second telescopic rod 55 and a camera 57. The second telescopic rod 55 is installed on two opposite sides of the fixed plate and is spaced apart from the first telescopic rod 53. The telescopic end of each second telescopic rod 55 is installed with a placement plate 56 in the vertical direction, and the camera 57 is installed on the side surface of the placement plate 56 away from the fixed plate 52. In addition to the outer dimensions of the automobile chassis parts, it is also necessary to detect whether there are cracks on the surface of the automobile chassis parts. The camera 57 can record the inner surface of the automobile chassis parts, and the inspector can observe whether there are cracks on the inner surface of the automobile chassis parts by using the camera 57. The second telescopic rod 55 is installed on the fixed plate 52. When the motor 51 drives the fixed plate 52 to rotate, while the outer dimensions of the automobile parts are detected, the second telescopic rod 55 and the placement plate 57 are driven to rotate at the same time, and then the camera 57 installed on the placement plate 57 records the inner surface of the entire automobile chassis parts for the inspector to check whether there are cracks on the inner surface of the automobile chassis parts. The length of the second telescopic rod 55 is shorter than that of the first telescopic rod 53, which prevents the placement plate 56 from colliding with the automobile chassis parts during the rotation process.

[0029] like Figure 3 As shown, a lighting lamp 58 is fixedly mounted on the side surface of the placement plate 56 away from the fixing plate 52. Since the camera 57 detects the inner surface of the automobile chassis part, the light will be blocked by the structure of the automobile chassis part itself, making the interior of the automobile chassis part relatively dark, which may cause the image taken by the camera 57 to be unclear and unable to identify whether there is a crack. Therefore, it is necessary to set a lighting lamp 58 on the placement plate 56 to supplement the light source to ensure that the image taken by the camera 57 is clear.

[0030] Example 2

[0031] This embodiment is similar to the above-mentioned embodiment 1, except that: Figure 1 As shown, the driving member 7 is a telescopic structure, which is installed on the top plate 3, and the telescopic end of the telescopic structure penetrates the top plate 3 and is connected to the positioning plate 4. Since the detection component 5 needs to extend into the automobile chassis parts, it will interfere with the movement of the automobile chassis parts, which is not convenient for replacing the automobile chassis parts to be detected. Therefore, it is necessary to set a structure that can drive the detection component 5 to move, so that the detection component 5 is extended into the automobile chassis parts when the detection is required, and the detection component 5 is removed from the automobile chassis parts when the detection is not required. The structure is a driving member 7, and the driving member 7 is a telescopic structure that can be retracted. The telescopic structure is installed on the top plate 3, and the telescopic end of the telescopic structure penetrates the top plate 3 and is connected to the positioning plate 4. The telescopic mechanism 7 is installed above the top plate 3 except the telescopic end, so that the telescopic structure can be installed on the top plate by relying on its own structure and will not fall. The positioning block 4 is connected to the telescopic end of the telescopic structure. When the detection starts, the telescopic structure extends, driving the positioning block 4 to move downward, and then driving the detection component 5 to extend into the automobile chassis parts. After the detection is completed, the telescopic structure contracts, driving the positioning block 4 to move upward, and then driving the detection component 5 to move out of the automobile chassis parts, without blocking the movement of the automobile chassis parts.

[0032] like Figure 1 As shown, a limit block 41 is also provided on the positioning plate 4, and a guide rod 8 is also provided between the base 1 and the top plate 3, and the guide rod 8 penetrates the limit block 41 and is slidably connected thereto. Since the detection assembly 5 determines that the external dimensions of the automobile chassis parts meet the requirements by rotating the detection plate 54 for one circle without colliding with the automobile chassis parts. Therefore, the position of the positioning plate 4 needs to remain stable and not deflect, so as to avoid causing an error in the detection conclusion. Therefore, a guide device is provided around the positioning plate 4 to ensure that the positioning plate 4 does not deflect during movement. The guide device includes a limit block 41 provided on the positioning plate 4, and a guide rod 8. The guide rod 8 penetrates the limit block 41 and is slidably connected thereto, so that the positioning plate 4 can only move along the length direction of the guide rod 8. When the positioning plate 4 deflects, the limit block 41 conflicts with the guide rod 8, thereby limiting the deflection of the limit block 41.

[0033] Example 3

[0034] This embodiment is similar to the above-mentioned embodiment 1, except that: Figure 1 As shown, a fixing structure for fixing the automobile chassis parts is also provided on the workbench 2 to ensure that the automobile chassis parts will not deflect during the detection process.

[0035] like Figure 1 , 4As shown, the fixed structure includes a fan 11, an air pipe and a fixed column 21 arranged on a workbench. The fixed column 21 is a hollow structure. A plurality of air holes are provided on the surface of the fixed column 21. The fixed column 21 is connected with an airbag 9 for holding the chassis of the automobile. One end of the air pipe is connected to the fan 11, and the other end of the air pipe is connected to the hollow structure of the fixed column 21. After the automobile chassis parts are placed, the fixed column 21 is located in the center of the automobile chassis parts. Then the fan 11 is started to blow air into the fixed column 21, and the airbag 9 on the fixed column 21 swells accordingly. Since the airbag 9 has a certain elasticity, the fan 11 blows air into it, and the airbag 9 expands accordingly until the airbag 9 fits the automobile chassis parts.

[0036] like Figure 4 As shown, the interior of the base 1 is a hollow cavity, the fan 11 is installed in the hollow cavity, and the other end of the air pipe extends above the workbench 2 and is connected to the hollow structure of the fixing column 21. Setting the interior of the base 1 as a hollow structure can free up space inside the base 1 for placing other structures.

[0037] like Figure 1 As shown, an opening is provided on one side of the base 1, and a dust screen 12 is provided on the opening. The fan 11 needs to inhale air when it is running, so an opening needs to be provided on the base 1 to leave a passage for air to enter. The dust screen 12 is provided on the opening of the base 1 to prevent dust in the air from entering the interior of the base 1, thereby affecting the operation of the fan 11.

[0038] Obviously, the above embodiments of the utility model are only examples for clearly explaining the utility model, and are not intended to limit the implementation methods of the utility model. For ordinary technicians in the relevant field, other different forms of changes or modifications can be made on the basis of the above description. It is not necessary and impossible to list all the implementation methods here. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the utility model should be included in the protection scope of the claims of the utility model.
