[0037] Figure 1 is a structural schematic view of a spraying jig checking device provided by an embodiment of the present application. The embodiment can be applicable to the checking of the jig before the coating of the automobile body. The spraying jig checking device can be arranged in any area where the device can be placed. As shown in Figure 1 , the spraying jig checking device is provided with a base 10. The base 10 is fixedly installed with a support 11. The support 11 is provided with a height limiting positioning rod 12 at an end away from the base 10. The height limiting positioning rod 12 is provided with a height limiting positioning pin 13 at an end away from the support 11. The connection between the height limiting positioning rod 12 and the support 11 is provided with an adjusting structure 20 for adjusting the position of the height limiting positioning rod 12.

[0038] The base 10 is stably placed on a horizontal plane. The support 11 is fixedly placed at an end of the base 10 at a 90° angle with the base 10. The support 11 is provided at the top with the height limiting positioning rod 12 and the height limiting positioning pin 13 fixed with the height limiting positioning rod 12. The height limiting positioning rod 12 is connected with the support 11 through the adjusting structure 20. According to different models of the spraying jig, the position of the height limiting positioning rod 12 can be adjusted through the adjusting structure 20, so that the position of the height limiting positioning pin 13 on the height limiting positioning rod 12 is consistent with the opening position of the normal spraying jig, thereby adapting to the checking of spraying jigs of different models.

[0039] With reference to Figure 1 , when the spraying jig 21 is checked, the spraying jig 21 is installed on the spraying jig checking device, and then the spraying jig 21 is opened to the height limiting positioning pin 13. If the spraying jig 21 is normally opened, the precision of the spraying jig 21 is normal. If the spraying jig 21 cannot be normally opened, the precision of the spraying jig 21 is abnormal, thereby realizing the checking of the spraying jig 21. Regardless of the change in the precision of the spraying jig 21, once it exceeds the allowed range, it will be detected by the spraying jig checking device as abnormal (the jig cannot be opened). The operation is simple and easy to realize.

[0040] The spraying jig checking device provided by the embodiment of the present application is characterized in that: a support 11 is fixedly installed on a base 10, a height-limiting positioning rod 12 and a height-limiting positioning pin 13 are arranged at the end of the support 11 away from the base 10, and the height-limiting positioning rod 12 is connected with the support 11 through an adjusting structure 20 capable of adjusting the position of the height-limiting positioning rod 12, so as to check the spraying jig 21. Compared with the previous method of checking the spraying jig by two persons in the equipment area by using a robot, the spraying jig checking device provided by the embodiment of the present application only needs one person to check the spraying jig, and the operation is simple. Meanwhile, the spraying jig checking device can be checked in any area where the spraying jig checking device can be placed, the personnel can be prevented from entering the equipment area for operation, the risk level is reduced, the collision risk existing in the checking by using the robot is avoided, the equipment and the vehicle body are protected, and the overall quality and the operation rate of the manufacturing site can be effectively improved.

[0042] In the embodiment, the jig rotating auxiliary frame 14 is arranged to assist in opening the spraying jig 21, and specifically, as shown in Figure 1 One end of the spraying jig 21 is fixed to the end of the jig rotating auxiliary frame 14 away from the support 11, the other end of the spraying jig 21 is fixed to the base 10, and the jig rotating auxiliary frame 14 can rotate in the vertical plane to assist in opening the spraying jig 21. The jig rotating auxiliary frame 14 can replace the program of opening and closing the door when the spraying jig is checked by using the robot, and the spraying jig 21 can be prevented from shaking randomly while the spraying jig 21 is opened, which is helpful to improve the checking accuracy.

[0043] With reference to the foregoing Figure 1 Optionally, the support 11 comprises two support columns 111, a rotating shaft 15 is arranged at the connection position of the jig rotating auxiliary frame 14 and the support 11, both ends of the rotating shaft 15 are connected with the two support columns 111 respectively, the jig rotating auxiliary frame 14 comprises a support rod 141, one end of the support rod 141 is provided with a through hole 142, and the rotating shaft 15 passes through the through hole of the support rod 142.

[0044] Exemplarily, as shown in Figure 1As shown, the jig rotating auxiliary frame 14 includes two support rods 141, both ends of the rotating shaft 15 pass through the through holes 142 of the support rods 141, and are connected with the support columns 111, so as to realize the rotatable connection between the jig rotating auxiliary frame 14 and the support 11. This structure can make the device more flexible and reliable, has adjustability, and improves the stability and coordination performance.

[0045] It should be noted that the connection structure between the jig rotating auxiliary frame 14 and the support 11 is not limited to the above embodiment, and in other embodiments, those skilled in the art can set it according to actual needs, as long as the jig rotating auxiliary frame 14 can rotate in the vertical plane.

[0046] Continuing to refer to Figure 1 Optionally, the first jig fixing lock 16 is arranged at the end of the base 10 away from the support 11, and the second jig fixing lock 17 is arranged at the end of the jig rotating auxiliary frame 14 away from the support 11.

[0050] Continuing to refer to Figure 1 Optionally, the jig rotating auxiliary frame 14 includes two support rods 141 and a jig fixing plate 18, the jig fixing plate 18 is fixed at the end of the two support rods 141 away from the support 11, and the second jig fixing lock 17 is fixed on the jig fixing plate 18.

[0051] The first jig fixing lock 16 and the second jig fixing lock 17 can be arranged according to the fixing lock of the spraying jig 21 fixed on the vehicle body, so as to simulate the opening and closing of the spraying jig 21 on the real car, make the checking result of the spraying jig checking device more accurate, effectively reduce the error rate, and improve the overall quality of the manufacturing site. Figure 1As shown, by setting a fixture fixing plate 18 at the end of the fixture rotation auxiliary frame 14 away from the bracket, sufficient space is provided for the second fixture fixing buckle 17, which can improve the firmness of the second fixture fixing buckle 17. This improves the firmness of the spraying fixture 21 when it is installed on the second fixture fixing buckle 17, which helps to make the calibration results of the spraying fixture calibration device more accurate, effectively reduce the error rate, and improve the overall quality of the manufacturing site.

The connecting rod 19 is fixedly connected to the two support rods 141 respectively. This structure can make the fixture rotation auxiliary frame 14 more reliable and reduce the problem of inaccurate calibration accuracy of the spraying fixture 21 due to shaking during rotation in the vertical plane.

[0054] Continue to refer to Figure 1 Optionally, the first fixture fixing buckle 16, the second fixture fixing buckle 17, and the height limiting positioning pin 13 are located in the same vertical plane.

The triangular structure can effectively improve stability, ensuring that the base 10 can be placed horizontally while the bracket 11 is placed vertically, thereby improving the calibration accuracy of the spraying fixture and increasing work efficiency.

[0058] The spraying fixture calibration device provided in this embodiment of the invention is applicable to the calibration of fixtures for all vehicle models and has an adjustable function. It can completely replace the method of inspecting fixtures with robots, effectively detect the fixture accuracy deviation caused by fixture defects or daily wear, and avoid opening and closing alarms and vehicle scrapping caused by changes in the opening of doors and hood due to fixture deviation.

[0059] Based on the same inventive concept, the embodiment of the present application also provides a spraying jig verification method, which is suitable for the spraying jig verification device provided by any of the above-mentioned embodiments.
