After one side of the sticking plate 206 contacts the sand box, friction will occur. Over a long period of time, the sticking plate 206 structure will wear out, resulting in errors in the device detection, thereby causing inaccurate calibration of the device. After the sticking plate 206 contacts the surface of the sand box and starts to push, the sand box drives the belt 2092 to run under the action of the connecting shaft 2091 while moving, thereby reducing the friction contact between the sticking plate 206 and the surface of the sand box, reducing the surface loss of the sticking plate 206, thereby improving the service life of the device and long-term detection accuracy.

The support frame 308 is separated from the upper mold of the sand box under the action of the spring shaft 309, and the connecting curved plate 20910 drives the support frame 308 to separate from the upper mold of the sand box, so that the work can be completed. Through the mutual cooperation between the structures, the multiple transmission effects of the structural power are realized, thereby completing the transmission effect of the structure, and the mutual cooperation between the structures is realized, which makes the operation simple and convenient.

[0039] Working principle: when using this device, the lower mold and the upper mold of the sand box need to be placed at the position of the conveyor belt 101 set on the bottom plate 1, and the lower mold of the sand box is driven by the conveyor belt 101 to move from the left to the right, and move to the bottom of the bracket 102, and the sand box starting device is identified by the infrared detection of the detection head 210. After the calibration unit 200 structure is started, the calibration unit 200 structure is driven by the hydraulic rod 201 structure to move downward as a whole, and the hydraulic rod 201 drives the second moving plate 211 to move downward and contact the top of the sand box through the transmission assembly 202 structure, and the top surface of the sand box is detected to be horizontal, and then the hydraulic rod 201 continues to move, so that the hydraulic rod 201 drives the first moving plate 203 to move through the transmission assembly 202, and the first moving plate 203, through the moving rod 204, with the cooperation of the deformation assembly 205, fits the pasting plate 206 with the outer side of the sand box. When the outer side of the sand box is tilted, the pasting plate 206 structure will be tilted, and the pasting plate 206 will be tilted. The detection head 210 set on the surface of the plate 206 will change, and then the hydraulic rod 201 continues to drive the first movable plate 203 to move through the transmission component 202 to apply pressure to the plate 206 structure through the deformation component 205 structure, so that the first movable plates 203 on both sides are attached to the plate 206 through the deformation component 205, so that the sand box is placed horizontally, completing the horizontal calibration task of the sand box, and then the hydraulic rod 201 is restarted. When the hydraulic rod 201 is recovered, the calibration unit 200 structure is reset, the upper mold of the sand box is fixed by the fixing unit 300 structure, and the upper mold of the sand box is driven to move upward by the calibration unit 200 structure. Then the detection head 210 identifies the lower mold of the sand box, and the calibration unit 200 structure restarts to drive the upper mold of the sand box to be placed on the top surface of the lower mold of the sand box, and the lower mold of the sand box is calibrated and placed horizontally by the calibration unit 200 structure, and the lower mold of the sand box is pushed to a horizontal position by the detection component 207 structure, thereby completing this work.
