By moving the L-shaped support frame 9, the two vertical fixing units 5 can find a suitable position and cooperate with each other to vertically fix the excavator door panel.

[0023] The slide slot frame 6 includes a third slide slot 14, which extends in the front-to-back direction and is located above the slide slot frame 6. A window extending left and right is opened on the slide slot frame 6, and a fourth slide slot 15 extending in the front-to-back direction is symmetrically arranged in the window.

[0024] There are two horizontal fixing units 7, which include a first support slider 16, which is slidably connected in the fourth slide slot 15, and a second screw hole is provided on the first support slider 16, which is through to the left and right, and a second screw rod 17 is rotatably connected to the second screw hole, and a second hand wheel 18 is fixedly connected to one end of the second screw rod 17, and a second fixing block 19 is fixedly connected to the other end of the second screw rod 17. By rotating the second hand wheel 18, the second screw rod 17 drives the second fixing block 19 to move left and right, and the second fixing block 19 is made of rubber material and will not produce indentations on the side surface of the excavator door panel.

[0025] The adjusting device 2 comprises an N-type support frame 20, a window penetrating from top to bottom is provided on the horizontal frame of the N-type support frame 20, a fifth slide slot 21 extending in the left and right directions is symmetrically arranged in the window, one end of the N-type support frame 20 is slidably connected to a first support frame 22, and the other end of the N-type support frame 20 is slidably connected to a second support frame 23. A hydraulic cylinder body can be installed on the left side of the first support frame 22, and a corresponding piston rod can be installed on the left side of the N-type support frame 20. The hydraulic piston structure is used as a driving structure, and the second support frame 23 is used as a limit support frame, so that the N-type support frame 20 can be smoothly moved up and down.

[0026] The adjusting device 2 is connected to a grinding device, which includes a grinding rod 24, one end of which is fixedly connected to a grinding head 25, and the other end of which is rotatably connected to a servo motor 26. The grinding head 25 is cylindrical, and the lower surface of the grinding head 25 can be used to grind the upper and lower surfaces of the excavator door panel, and the side surface of the grinding head 25 can be used to grind the side surface of the excavator door panel.

[0027] A second support slider 27 is fixedly connected below the servo motor 26, and the second support slider 27 is slidably connected in the fifth slide groove 21; a through hole is provided in the second support slider 27, and the grinding rod 24 passes through the through hole. The grinding rod 24 can be driven by the servo motor 26 to drive the grinding head 25 to rotate at a high speed, thereby grinding the door panel of the excavator.

[0028] A slider is fixedly connected to the lower part of the first support frame 22, and the first support frame 22 slides in the first slide groove 3 through the slider; a slider is fixedly connected to the lower part of the second support frame 23, and the second support frame 23 slides in the third slide groove 14 through the slider. The slider in the first slide groove 3 can be driven by a motor to move, and the slider in the third slide groove 14 serves as a limit block, so that the adjustment device 2 can move forward and backward smoothly.

[0029] Before use, move the horizontal fixing unit 7 to both ends of the fourth chute 15 so as not to affect the use of the grinding device. When in use, place the excavator door panel on the bottom plate 1, with one side of the excavator door panel close to the baffle 4, and fix it by squeezing the upper surface of the excavator door panel through two vertical fixing units 5. At this time, the other side of most conventional excavator door panels will be located above the waste trough 8, and the grinding device is moved to the rightmost end of the fifth chute 21 by the motor, and then the N-type support frame 20 is moved up and down until the bottom of the grinding head 25 is slightly lower than the upper surface of the bottom plate 1, and then the grinding device is moved by the motor to make the side of the grinding head 25 close to the side of the excavator door panel, turn on the servo motor 26 to rotate the grinding head 25, and then move it back and forth by controlling the adjustment device 2, so as to grind the side of the excavator door panel, and most of the waste after grinding will fall into the waste trough 8. The remaining sides of the excavator door panel can be polished in the same way. After the side grinding of the excavator door panel is completed, the grinding head 25 is controlled by the motor to the top of the excavator door panel, so that the lower surface of the grinding head 25 is close to the upper surface of the excavator door panel, and the side of the excavator door panel is squeezed and fixed by two horizontal fixing units 7, and the servo motor 26 is turned on to rotate the grinding head 25. The motor is controlled to make the grinding head 25 perform an S-shaped full coverage movement on the upper surface of the excavator door panel. When the grinding device moves to a position close to the vertical fixing unit 5, the two vertical fixing units 5 can be moved to the two ends of the second slide groove 13, so as not to affect the use of the grinding device. At this time, the excavator door panel is fixed by the vertical squeezing effect of the grinding device on the excavator door panel, so that the remaining part of the excavator door panel is fully polished. After the grinding is completed, the remaining waste on the upper surface of the excavator door panel is tilted to the waste trough 8 for centralized treatment.
