This is not only labor-intensive but also inefficient and difficult to guarantee in terms of grinding quality, failing to meet the needs of large-scale production. Therefore, it is necessary to provide a new specialized equipment for grinding the bottom plate of the central trough to solve the above-mentioned technical problems. Utility Model Content

[0037] The working principle of the special equipment for grinding the bottom plate of the central groove provided by this utility model is as follows:

[0038] First step: Before the special equipment for grinding the bottom plate in the middle tank is put into operation, it is in the initial state. The grinding host 1 is located far away from the positioner 2 to leave space for placing the workpiece. The positioner 2 is located at any angle. The grinding range (width and length) of the workpiece is input into the control system equipment 4. The control system equipment 4 receives and stores this information to provide instructions for subsequent grinding work.

[0039] The second step: The middle groove is hoisted and placed on the positioner 2 using hoisting equipment. With the help of the laser line marker 1210 installed on the translation slide plate 121, the operator can intuitively observe and adjust the angle of the middle groove so that the middle groove is parallel to the travel track 114 (i.e. the travel direction of the grinding host 1), ensuring that the grinding work can be carried out in the correct direction. In addition, the travel motor 115 is controlled to drive the drive wheel 113 to move on the travel track 114, so that the grinding host 1 moves as a whole to the appropriate working starting position. Then, the translation motor 123 and the lifting motor 127 drive the translation mechanism 12 and the lifting mechanism 13 respectively to accurately move the wire brush roller 145 to the starting grinding position.

[0040] The third step: After all components are adjusted to their positions, the operator presses the start button, and the control system device 4 issues a command. The grinding motor 142 drives the input shaft of the reduction gearbox 144 to rotate through the long transmission shaft 143. The main gear 150 on the input shaft meshes with two driven gears 149 and auxiliary gear 151, causing the two rotating shafts 147 to rotate. The bevel gear 146 meshes with the bevel gear 148, which ultimately drives the two wire brush rollers 145 to rotate at high speed. According to the grinding range information pre-input by the control system device 4, the wire brush rollers 145 automatically move back and forth along the surface of the bottom plate in the central groove for grinding under the coordinated action of the travel motor 115, the translation motor 123 and the lifting motor 127 until the entire grinding task is completed. After grinding, the gantry frame 111 returns to its initial state under the drive of the corresponding motor, leaving space for hoisting and unloading the workpiece, and then the next grinding cycle can be started.
