[0021] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0022] like Figure 1 and Figure 2As shown, the utility model provides a technical solution: a vehicle main driving under guard plate assembly inspection tool, including a base 1, a box body 11 is installed on the top of the base 1, and a controller 12 is installed at one end of the box body 11, and detection components 2 for detecting the guard plate are installed on both sides of the box body 11, and the detection component 2 includes a support rod 1 21 and a support rod 22, and the support rod 1 21 and the support rod 22 are respectively installed at both ends of the box body 11, and a size detection box 23 and an aperture detection box 24 are installed at one end of the support rod 1 21 close to the box body 11, and a laser detection box 25 is installed at one end of the support rod 22 close to the box body 11. This structure makes it possible to inspect the guard plate. Quality inspection in all aspects is carried out to better ensure the production quality of the guard plate. A fixing mechanism for placing the guard plate is installed on the upper side of the base 1. The fixing mechanism includes a placement component 3 for placing the guard plate, a clamping component 4 for fixing the guard plate and a driving component 5 for driving the clamping component 4 to clamp. The placement component 3 includes a single-head motor 31, which is installed in a groove on the upper side of the box body 11. The output end of the single-head motor 31 is connected to a connecting block 32, and a tray 33 is installed on the top of the connecting block 32. This structure can be used to place the guard plate that needs to be inspected, and the guard plate can be rotated and adjusted to make the inspection more comprehensive.

[0023] As an implementation method in this embodiment, Figure 3 and Figure 4As shown, the clamping assembly 4 is provided with two groups, and the two groups of clamping assemblies 4 are respectively installed on both sides of the bottom end of the tray 33, and the clamping assembly 4 includes a fixing rod 41, and the fixing rod 41 is fixedly connected to the bottom end of the tray 33. Both ends of the fixing rod 41 are provided with movable grooves 42, and screw rods 43 are rotatably installed in the two groups of movable grooves 42. A connecting rod 44 is connected between the two groups of screw rods 43, and the connecting rod 44 is rotatably installed in the fixing rod 41 through a driving assembly 5. A sleeve rod 45 is threadedly sleeved on the surface of the screw rod 43. The movable groove 42 and the sleeve rod 45 are both quadrilaterals, so that the sleeve rod 45 can be limited to prevent the sleeve rod 45 from rotating. The inner diameter of the movable groove 42 is adapted to the outer diameter of the sleeve rod 45, so that the movement of the sleeve rod 45 is more stable, and a clamping plate 46 is fixedly connected to the side of the top of the sleeve rod 45 away from the fixed rod 41. This structure makes it possible to move the guard plate placed on the tray 33 The clamping and fixing make the guard plate more firmly placed and not prone to offset and falling during rotation, making the guard plate detection result more accurate. The two groups of clamping components 4 are driven and clamped by the driving component 5. The driving component 5 includes a mounting slot 51 and a double-headed motor 52. The mounting slot 51 is opened near the center of the fixing rod 41. The connecting rod 1 44 passes through the mounting slot 51 and is connected to the screw 43. The double-headed motor 52 is fixedly installed on the bottom end of the tray 33 through a pad. Both ends of the double-headed motor 52 are connected to the connecting rod 2 53, and one end of the connecting rod 2 53 extends into the mounting slot 51 and is connected to a main bevel gear 54. One side of the main bevel gear 54 is meshed with a secondary bevel gear 55, and the secondary bevel gear 55 is fixedly sleeved on the surface of the connecting rod 1 44. This structure makes it possible to clamp the guard plate by driving the four groups of clamping plates 46 to move simultaneously, thereby greatly increasing the practicality of the device.

[0024] It should be noted that the size detection box 23, the aperture detection box 24, the laser detection box 25, the single-head motor 31 and the double-head motor 52 are all electrically connected to the controller 12, so that the size detection box 23, the aperture detection box 24, the laser detection box 25, the single-head motor 31 and the double-head motor 52 can be controlled by the controller 12.

[0025] As an implementation method in this embodiment, Figure 5 As shown, a protective component 6 is installed at one end of the clamping plate 46 close to the tray 33, and the protective component 6 includes a T-slot 61 and a mounting plate 62. The T-slot 61 is opened at the end of the clamping plate 46 close to the tray 33, and a rubber pad 63 is glued to the end of the mounting plate 62 away from the clamping plate 46. A T-block 64 is connected to the end of the mounting plate 62 close to the clamping plate 46, and the T-block 64 is inserted in the T-slot 61. This structure can reduce the friction on the guard plate during clamping, thereby greatly reducing wear, and when the rubber pad 63 is damaged after long-term use, it is easy to replace the rubber pad 63, which greatly increases the convenience of the device.

[0026] Working principle: If the guard plate needs to be inspected, just place the guard plate to be inspected on the tray 33, and then start the double-headed motor 52 through the controller 12 to drive the two sets of connecting rods 53 to rotate, and the connecting rod 53 drives the main bevel gear 54 to rotate. Through meshing, the main bevel gear 54 drives the secondary bevel gear 55 to rotate, and the secondary bevel gear 55 drives the connecting rod 1 44 to rotate. The connecting rod 1 44 can drive the screw rod 43 to rotate. Through the rotation of the thread, the screw rod 43 can drive the sleeve rod 45 to slide in the movable groove 42, and the sleeve rod 45 drives the clamping plate 46 to approach the tray 33, and the clamping plate 46 drives the rubber pad 63 to approach the guard plate until the rubber pad 63 is tightly fitted with the guard plate, and the clamping plate 46 can clamp the guard plate. After fixing, the size detection box 23, the aperture detection box 24 and the laser detection box 25 can be controlled by the controller 12 to detect the guard plate, and the single-head motor 31 is started to drive the connecting block 32 to rotate, and the connecting block 32 drives the tray 33 to rotate, so that the tray 33 can drive the guard plate to turn the direction, so that the detection of the guard plate is more comprehensive and accurate. Finally, after the detection is completed, the guard plate can be removed from the tray 33, which greatly increases the practicality of the device;

[0027] In addition, when the rubber pad 63 is damaged and needs to be replaced, it is only necessary to pull the rubber pad 63 upwards to drive the mounting plate 62, and the mounting plate 62 drives the T-block 64 to slide in the T-slot 61 until the T-block 64 is removed from the T-slot 61 to complete the disassembly, and then the mounting plate 62 with the new rubber pad 63 glued thereon drives the T-block 64 to align with the T-slot 61 and insert it to complete the installation.

[0028] The above embodiments are only used to illustrate the technical solution of the present invention, but not to limit it.
