[0016] Figure 1 It is the structure schematic diagram of the utility model.

[0017] As shown in the accompanying Figure 1 It is a sanding machine of polishing both sides, including polishing part 1, polishing part moving mechanism 2, work piece horizontal conveying table 3, work piece carrier 4, work piece lifting mechanism 5, work piece automatic turning mechanism 6, and polishing part 1 is composed of motor and sanding wheel, and polishing part 1 is installed on polishing part moving mechanism 2, and polishing part moving mechanism 2 is located above work piece horizontal conveying table 3, and work piece horizontal conveying table 3 is connected with work piece carrier 4, and work piece horizontal conveying table 3 is installed with work piece lifting mechanism 5 on left and right sides, and work piece horizontal conveying table 3 is located between two symmetrical work piece automatic turning mechanisms 6.

[0018] The workpiece automatic turning mechanism 6 comprises an opening and closing mechanism 61, a stand 62, a clamping part 63, and a clamping part rotating mechanism 64. The stand 62 is fixed on the two sliding seats of the opening and closing mechanism 61. The clamping part rotating mechanism 64 is installed in the stand 62. The clamping part 63 is connected to the clamping part rotating mechanism 64. The clamping part 63 is rotatably connected to the side of the stand 62.

[0019] The opening and closing mechanism 61 comprises a positive and reverse threaded screw rod, a nut, a sliding seat, a motor, and a cylinder. The positive and reverse threaded screw rod is rotatably connected in the cylinder. The positive and reverse threaded screw rod is threadedly connected with the nut. The two nuts are respectively connected to the two sliding seats. The two sliding seats are slidably connected to the cylinder. The output shaft of the motor is connected to the positive and reverse threaded screw rod.

[0020] The motor drives the positive and reverse threaded screw rod to rotate, so as to drive the two nuts to move reversely with the two sliding seats.

[0021] The clamping part 63 is a cylinder clamping jaw.

[0022] The clamping part rotating mechanism comprises a rack 64, a gear 65, and a rack lifting cylinder 66. The piston rod of the rack lifting cylinder 66 is fixed with the rack 64. The rack 64 is engaged with the gear 65. The gear 65 is rotatably connected in the stand 62. The gear 65 is fixed on the cylinder of the clamping part 63.

[0023] The rack lifting cylinder 66 drives the rack 64 to lift, so as to drive the gear 65 and the clamping part 63 to rotate.

[0027] The working mode of the present application is as follows: first, the workpiece is placed into the workpiece carrier 4. Then, the workpiece horizontal conveying table 3 moves the workpiece horizontally forward and stops when the workpiece reaches the processing position. At this time, the polishing part moving mechanism 2 drives the polishing part 1 to polish the upper surface of the workpiece.

[0028] Then the left and right workpiece lifting mechanisms 5 drive the top plate to move up, thereby lifting the workpiece up from the workpiece carrier 4. Then the left and right clamping portions 63 respectively move horizontally towards the workpiece until the two clamping portions 63 clamp the left and right sides of the workpiece, at which time the top plate of the workpiece lifting mechanism 5 moves down to reset. Then the rack lifting cylinder 66 drives the rack 64 to move, the rack 64 drives the gear 65 and the clamping portion 63 to rotate, thereby turning the workpiece by 180 degrees. Then the top plate of the workpiece lifting mechanism 5 moves up again to receive the workpiece, and the two clamping portions 63 release the workpiece and reset. Then the workpiece is placed back on the workpiece carrier 4, and finally the polishing portion 1 can polish the lower surface of the workpiece.
