[0042] The belt sander module D in this embodiment includes a belt sander frame D1, a lower grinding wheel D2, a drive wheel D3, a tension wheel D4, an upper grinding wheel D5, a belt sander cover D6, a rigid electric spindle D7, a floating air spindle D8, a belt sander safety light curtain D9, and a sanding belt D10.

[0043] The quick-change module E in this embodiment includes a quick-change seat E1, a rotary clamping cylinder E2, a quick-change flange E3, a pressure plate E4, a quick-change tool end E5, and a quick-change fixture E7. The quick-change seat E1 is mounted on the base module A. The cylinder of the rotary clamping cylinder E2 is mounted on the quick-change seat E1. The piston rod of the rotary clamping cylinder E2 is connected to the pressure plate E4. The quick-change tool end E5 and the quick-change fixture E7 are respectively mounted on both ends of the quick-change flange E3. The quick-change flange E3 is placed on the quick-change seat E1. The industrial robot G is provided with a quick-change robot end G1, which is connected to the quick-change tool end E5. A sensor E6 is mounted on the quick-change seat E1. A stop block E8 is mounted on the quick-change flange E3, and the stop block E8 cooperates with the sensor E6.

[0044] Specifically, this teaching grinding and polishing workbench can be used in school teaching. It has all the functions of a robotic grinding and polishing workstation. During operation, the corresponding quick-change fixture E7 is selected according to the workpiece to be processed. That is, the pressure plate E4 is lifted and rotated by rotating the clamping cylinder E2, and then connected to the quick-change tool end E5 through the quick-change robot end G1 on the industrial robot G, thereby realizing the installation of the quick-change fixture E7. When it is necessary to change the quick-change fixture E7, the pressure plate E4 is lifted and rotated by rotating the clamping cylinder E2, and the quick-change tool end E5 connected to the quick-change robot end G1 on the industrial robot G is placed on the quick-change seat E1. The sensor E6 and the stop block E8 can detect whether the quick-change tool end E5 is placed in place.

[0045] The workpiece is manually placed on tray B1, and its position is determined by 3D camera C7. Then, the quick-change fixture E7 on industrial robot G picks up the workpiece from tray B1. Industrial robot G places the workpiece on belt sander module D for grinding, polishing and other processing. When industrial robot G picks up and rotates the workpiece, the workpiece will collide with the detection collision rod F once, and the collision will be counted once. After processing, the workpiece is placed back on tray B1 by industrial robot G, and the workpiece is manually removed. The safety performance can be improved by setting a safety light curtain during workpiece processing.

[0046] When the industrial robot G picks up or places a workpiece using the quick-change fixture E7, the floating structure B2 and the limiting structure B3 prevent the quick-change fixture E7 from making hard contact with the tray B1. That is, when the quick-change fixture E7 contacts the tray B1, the tray B1 can compress the floating top rod B25 downward, thereby causing the tray B1 to move downward along the limiting screw B31. When the quick-change fixture E7 separates from the tray B1, the floating top rod B25 can be lifted up by the floating spring B24, thereby causing the tray B1 to rise. During the rising process of the tray B1, the limiting screw B31 can limit the height of the tray B1.

[0047] Furthermore, it should be noted that the specific embodiments described in this specification may differ in the shape and name of their components. The above description is merely illustrative of the structure of this utility model. All equivalent or simple variations made based on the structure, features, and principles described in this utility model are included within the protection scope of this utility model. Those skilled in the art to which this utility model pertains may make various modifications or additions to the described specific embodiments or use similar methods to replace them, as long as they do not deviate from the structure of this utility model or exceed the scope defined by the claims, all of which should fall within the protection scope of this utility model.
