[0017] The specific implementation of the present utility model will be described below in conjunction with the accompanying drawings. Figures 1 to 4As shown: an automatic grinding and polishing device, including a frame, a working platform 1 is arranged on the top of the frame, a workpiece rotating motor 2 is arranged on the bottom end surface of the working platform 1, the output end of the workpiece rotating motor 2 is connected to a rotating support 3 rotatably supported on the top surface of the working platform, a supporting frame 4 is arranged on the working platform 1, a first Z-axis cylinder 5 is arranged on the top of the supporting frame 4, the working end of the first Z-axis cylinder 5 is connected to a Z-axis slide 6, the Z-axis slide 6 is slidably connected to the supporting frame 4 through a Z-axis slide rail 7, a second Z-axis cylinder 8 is arranged on the bottom end surface of the Z-axis slide 6, a rotating pressure head 9 is arranged at the end of the working axis of the second Z-axis cylinder 8, and the rotating pressure head 9 is located directly above the rotating support 3,

[0018] A grinding belt drive motor 10 is also provided on the bottom end surface of the working platform 1. The working end of the grinding belt drive motor 10 is connected to a grinding belt drive wheel 11 rotatably supported on the top end surface of the working platform 1. A fixed support wheel 12, an inner tensioning wheel mechanism and an outer tensioning wheel mechanism are also provided on the working platform 1.

[0019] The inner tensioning wheel mechanism comprises a tensioning slide 13 slidably connected to a planar guide rail, the planar guide rail is arranged on the top surface of the working platform 1, the tensioning slide 13 is connected to the working end of the inner tensioning cylinder 14, and an inner tensioning roller 15 with a longitudinal axis is arranged on the inner tensioning slide 13.

[0020] The external tensioning wheel mechanism comprises an external tensioning support frame 16 fixedly arranged on the working platform 1, an external tensioning cylinder 17 is arranged on the external tensioning support frame 16, and an external tensioning roller 18 with a longitudinal axis is arranged on the working end of the external tensioning cylinder 17.

[0021] The abrasive belt driving wheel 11 , the fixed support wheel 12 and the inner tensioning roller 15 jointly support the abrasive belt 19 from the inside, and the outer tensioning roller 18 can press the abrasive belt 19 from the outside, and the abrasive belt 19 can contact the workpiece 20 fixed on the rotating support platform 3 .

[0022] The working process of the automatic grinding and polishing device of the embodiment of the utility model is as follows: when it is necessary to grind the outer wall of the workpiece 20, first place the workpiece 20 on the rotating platform 3, and then control the first Z-axis cylinder 5 and the second Z-axis cylinder 8 to work through the control system, the first Z-axis cylinder 5 drives the Z-axis slide 6 downward, and the second Z-axis cylinder 8 drives the rotating pressure head 9 downward while moving downward, and the rotating pressure head 9 presses the workpiece 20 on the rotating platform 3. At this time, the workpiece 20 is locked in the Z-axis direction, but can rotate freely under the drive of the rotating platform 3. Since the rotating pressure head 9 is a double-layer structure that can rotate relatively (refer to the plane bearing), it will not block the rotation of the workpiece 20;

[0023] After the workpiece 20 is positioned, the control system controls the inner tensioning wheel mechanism and the outer tensioning wheel mechanism to move. The inner tensioning cylinder 14 in the inner tensioning wheel mechanism drives the inner tensioning slide 13 to move. The inner tensioning roller 15 provided on the tensioning slide 13 supports the grinding belt 19 from the inside to make it tensioned.

[0024] The outer tensioning cylinder 17 in the outer tensioning wheel mechanism drives the outer tensioning roller 18 to move, and the outer tensioning roller 18 presses the sanding belt 19 from the outside to make it tensioned;

[0025] The grinding belt 19 in the tensioned state will be in close contact with the outer wall of the workpiece 20. Start the workpiece rotation motor 2 to drive the workpiece 20 to rotate, start the grinding belt drive motor 10, and drive the grinding belt 19 to move through the belt drive wheel 11. The rotation direction of the workpiece 20 is opposite to the movement direction of the grinding belt 19, which can improve the grinding efficiency of the workpiece 20.

[0026] After the grinding of the first workpiece 20 is completed, the inner tensioning cylinder 14 and the outer tensioning cylinder work in reverse, the grinding belt 19 returns to the initial position, the rotating pressure head 9 moves upward, the grinded workpiece 20 is removed from the rotating support 3, and the second workpiece 20 to be polished is placed on it, and the above operation is repeated.
