The gantry crane track conveyor 5 primarily propels the laser cutting head or grinding device 2 forward and backward along the track. This allows the laser cutting head to be positioned at various workpiece locations for precise cutting. Furthermore, the gantry crane track conveyor 5 works in conjunction with the grinding device 2 to transport the workpiece to the grinding area for further processing. This design ensures the coordinated operation of all links in the cutting and grinding process through the precise coordination of the motor 28 and the rack rod 212. The bottom of the connecting plate 21 is fixedly connected to the connecting block 22, and the back of the connecting block 22 is rotatably connected to the first rotating rod 23 through a bearing.

Especially the grinding part, which adopts a complex transmission mechanism and rotation control system, so that the equipment can not only perform efficient cutting, but also automatically perform subsequent fine processing as needed, greatly improving the efficiency of the production line and the quality of the workpiece. Through the grinding device 2 on the box body 1 and the gantry crane track conveying device body 5, the automatic adjustment and transportation of the laser cutting head are realized.The design of the grinding device 2 allows for surface treatment of cut workpieces to remove burrs and improve surface quality. A rack block is fixedly connected to the middle portion of the rack rod 212. The addition of this rack block enhances the meshing between the rack rod 212 and the first circular gear 29, improving transmission stability and accuracy. The design of the grinding device 2 focuses on precisely controlling the motion trajectory of the grinding disc 27 and performing surface treatment based on the workpiece's position and cutting state. Through the linkage of the rotating block 24 and the limiting rotating rod 25, the grinding disc 27 can finely grind the workpiece surface, removing burrs and surface irregularities generated during the cutting process and improving the workpiece's surface quality.

The plate is cut by the laser cutting head, and the driver 61 drives the top moving plate to move along the moving trajectory of the connecting block 22, driving the gantry crane track conveying device body 5 to drive the rack block at the top of the first circular gear 29 rack rod 212 to engage. There are only four rack blocks at the top of the rack rod 212, and the first circular gear 29 drives the first rotating rod 23 to rotate.

A third slot 37 is provided on the left side of the inner wall of the box body 1. The back of the connecting plate 21 is fixedly connected to a restraining rod 31. The right side of the movable sleeve 26 is fixedly connected to a first limit plate 39, and the left side of the movable sleeve 26 is fixedly connected to a second limit plate 310. The telescopic rod 32 and the limiting edge 38 are used for precise grinding of the plate after the laser cutting process to ensure grinding accuracy. The second limit block 36 is slidably connected to the inner wall of the third slot 37. The restraining rod 31 flexibly extends through the box body 1 to the left and is slidably connected to the top of the connecting rod 35. The design of the restraining rod 31 allows the second limit block 36 to slide freely on the inner wall of the box body 1, improving the accuracy of grinding. The second stopper 36 engages with the second stopper plate 310. The addition of the stopper device 3 significantly enhances the ability to precisely polish the cut workpiece.

The second limit block 36 slides in the third slide groove 37 to move forward and backward, so that the first limit block 34 and the second limit block 36 always maintain the same horizontal line with the connecting block 22. The operation of the equipment relies on the cooperation of the electric slide 62 and the driver 61 and other automation systems. It can automatically adjust the working status of the cutting, grinding, cleaning and other modules according to different needs. In particular, during the grinding process, the equipment automatically adjusts the pressure and rotation speed of the grinding disc 27 according to different workpiece thickness, material properties, cutting depth and other factors to ensure that the surface of each workpiece can achieve the best effect. Example 3

[0023] See also Figures 1-11On the basis of the first embodiment, a cleaning device 4 is provided on the box body 1, and the cleaning device 4 includes a rack 41, which is fixedly connected to the left side of the second limit block 36. The left side of the box body 1 is rotatably connected to a second rotating rod 42 through a bearing. The outer wall of the second rotating rod 42 is fixedly sleeved with a second circular gear 43, and the second circular gear 43 and the rack 41 are meshed with each other.

A second slot 48 is formed on the left side of the inner wall of the housing 1. A slider is slidably connected to the inner wall of the second slot 48, and the slider is fixedly connected to the left side of the push block 49. A third rotating rod 45 extends movably through the housing 1 to the left. The second rotating rod 42 and the outer wall of the third rotating rod 45 are connected by a sprocket chain 44. When used together, the sprocket and chain can effectively transmit mechanical power and achieve high transmission efficiency. The contact between the chain and sprocket ensures continuous power transmission and reduces sliding friction. Therefore, under the same conditions, the efficiency of a chain drive system is generally higher than that of other systems such as belt drives, and it can withstand higher loads without slipping. This makes the sprocket particularly effective in high-load and high-torque transmission applications. It is used to clean the grinding area after grinding, remove residue, and maintain a clean working environment.

The cleaning device 4 drives a series of transmission mechanisms such as the second rotating rod 42, the sprocket chain 44, and the third rotating rod 45 through the linkage between the rack 41 and the second circular gear 43, so that the movable rod 47 and the push block 49 can effectively clean the grinding area. By sliding the slider in the second chute 48, the push block 49 performs reciprocating motion, discharging waste into the waste opening 410, thereby keeping the equipment clean and the cutting area hygienic.

[0024] When the above-mentioned equipment is in use, when the second limit block 36 drives the rack 41 to move backward, the rack 41 drives the second circular gear 43 to rotate, the second circular gear 43 drives the second rotating rod 42 to rotate, the second rotating rod 42 drives the sprocket chain 44 to rotate, the sprocket chain 44 drives the third rotating rod 45 to rotate, the third rotating rod 45 drives the fixed rod 46 to rotate, the fixed rod 46 drives the movable rod 47 and the push block 49 to move toward the front, and the slider on the left side of the push block 49 slides on the inner wall of the second slide groove 48, causing the push block 49 to reciprocate and push the debris generated by grinding out from the waste port 410.
