A dust collection hole 11 is opened on the workbench, and a dust collection box 12 is fixedly connected to the bottom of the grinding mechanism corresponding to the position of the dust collection hole 11. In the specific implementation, the workbench 1 provides a stable processing environment, which can carry various processing tools and structural parts to ensure the stability of the grinding process. The processing positioning component can accurately and quickly position and fix the automotive structural parts to be polished, thereby improving the processing accuracy and efficiency. Through the coordinated use of the fixed table 2, the clamping frame 3 and the pressure block 4, the stable clamping of the structural parts is achieved, ensuring the stable position of the workpiece during the grinding process. The fixed table 2 provides support for the clamping frame 3 to ensure that the clamping frame 3 and the pressure block 4 can stably clamp the workpiece. The clamping frame 3 is used in conjunction with the pressure block 4 to achieve a firm clamping of the workpiece; the pressure block 4 has a large contact area and friction force, which can ensure that the workpiece does not move during the grinding process. The transmission belt 5 realizes automatic loading and unloading of the workpiece, thereby improving the processing efficiency. The translation adjustment mechanism can realize the precise movement and positioning of the grinding mechanism to meet the processing requirements of different workpieces. Through the cooperation of the servo motor 7 and the lifting mechanism, the grinding mechanism can be adjusted in the horizontal and vertical directions. The mobile frame 6 serves as a supporting platform for the lifting mechanism and the servo motor 7 to ensure that they can work stably. The servo motor 7 provides power for the translation adjustment mechanism to achieve precise movement of the grinding mechanism. The grinding mechanism grinds the workpiece through the grinding head 8 to remove burrs and uneven parts on the surface of the workpiece. The grinding head 8 directly contacts the surface of the workpiece to perform the grinding operation.The driving component provides stable power output to ensure that the grinding head 8 can work normally.

[0016] like Figure 2 As shown, on the basis of the above method, the lifting mechanism includes a linear guide 13, a slider 14, a guide column 15 and a driving belt 16.

[0017] like Figure 2 As shown, on the basis of the above method, the driving component includes a driving motor 17, a fixing plate 18 and a driving shaft 19. The fixing plate 18 is arranged on one side of the guide column 15, and the driving motor 17 is arranged on the fixing plate 18.

In the specific implementation, the driving motor 17 is used as a power source and can provide rotational power stably and efficiently. Through reasonable selection and design, it can be ensured that the output power of the driving motor 17 matches the requirements of the grinding head 8, so as to achieve efficient grinding. The fixing plate 18 is used as a supporting and fixing structure to stably install the driving motor 17 on one side of the guide column 15. The driving motor 17 is connected to the grinding head 8 through the driving shaft 19, so as to realize the transmission of power. The design of the driving shaft 19 can ensure the stability and accuracy of the transmission, reduce the energy loss and error in the transmission process, and improve the accuracy and efficiency of grinding.
[0018] like Figure 1As shown, on the basis of the above method, a dust hood 20 and an industrial vacuum cleaner 21 are further provided on the side of the dust box 12. In the specific implementation, the dust hood 20 is reasonably designed to collect dust to the maximum extent. The dust generated during the grinding process is guided to the industrial vacuum cleaner 21 to improve the dust collection efficiency. The industrial vacuum cleaner 21 further processes and collects the dust collected by the dust hood 20 to ensure the cleanliness and safety of the working environment.
[0019] like Figure 1 As shown, on the basis of the above method, a protrusion 22 for increasing the clamping friction force is further provided on the relative inner wall of the pressure block 4.

[0021] In the specific working process of the grinding device for processing automobile structural parts of the present invention, the workpiece is loaded, and the transmission belt 5 starts to run, and the automobile structural parts to be ground are automatically conveyed to the top of the fixed table 2. The automatic loading function of the transmission belt 5 greatly improves the production efficiency. After the workpiece reaches the appropriate position, the transmission belt stops running. The operator or the manipulator places the workpiece on the clamping frame 3, and then adjusts the position of the clamping frame 3 and the pressing block 4, and uses the protrusion 22 on the pressing block 4 to increase the clamping friction force to ensure that the workpiece is firmly clamped and the position is stable. The pressing block 4 contacts a large area and effectively prevents the workpiece from moving during the grinding process; the translation adjustment mechanism is driven by the servo motor 7 to accurately control the position of the grinding mechanism in the horizontal and vertical directions. The cooperation of the linear guide 13 and the slider 14 ensures the smoothness and precision of the lifting action, and the driving belt 16 accurately controls the position of the slider 14 to achieve high-precision adjustment of the grinding mechanism. The drive motor 17 is started, and a stable rotational power is transmitted to the grinding head 8 through the drive shaft 19. The rotating arm 9 can adjust the angle and position of the grinding head 8 as needed to adapt to the complex shape of the workpiece. The grinding head 8 is fixed by the connecting piece 10 to precisely grind the surface of the workpiece to remove burrs and uneven parts. During this process, the laser rangefinder 23 monitors the size, position and deformation of the workpiece in real time, provides real-time feedback to the operator, and facilitates timely adjustment of grinding parameters or strategies. The dust generated during the grinding process falls into the dust box 12 through the dust collection hole 11 on the workbench 1. The dust hood 20 on the side of the dust box 12 expands the dust collection range, and the industrial vacuum cleaner 21 further processes and collects the collected dust to ensure the cleanliness and safety of the working environment. After the grinding operation is completed, the servo motor 7 drives the translation adjustment mechanism to move the grinding mechanism away from the workpiece. The operator or the manipulator automatically unloads the workpiece that has been polished through the reverse operation of the transmission belt 5, and prepares for the next cycle of loading process. During the entire working process, the various components work together to achieve precise positioning, stable clamping, efficient grinding and effective collection of dust of automobile structural parts, ensuring processing accuracy, efficiency and clean working environment, and meeting the batch processing requirements of automobile structural parts.
