[0010] See also Figure 1 and Figure 2 The workpiece turning device includes a bracket 1, on which a lifting plate 2 and a lifting drive 21 are provided. The lifting plate 2 can move up and down relative to the bracket 1, and the lifting drive 21 is used to drive the lifting plate 2 to move up and down. The lifting drive 21 can be a cylinder or a linear motor, etc. A clamping mechanism is provided on the lifting plate 2, and the clamping mechanism is below the lifting plate and is used to clamp the workpiece. The clamping mechanism includes a left slide 3, a right slide 4, a sliding drive 5 and a gear 50 arranged on the lifting plate 2, and the left slide 3 and the right slide 4 are positively opposite. A guide rail is provided on the lifting plate 2, and a slider that cooperates with the guide rail is provided on the left slide 3 and the right slide 4. Through the cooperation of the guide rail and the slider, the left slide 3 and the right slide 4 are installed on the lifting plate 2, and can move left and right relative to the lifting plate 2 along the guide rail, and the distance between the left slide 3 and the right slide 4 can be changed by moving. The left slide 3 is provided with a left rack 51 along its moving direction, and the right slide 4 is provided with a right rack 52 along its moving direction. The left rack 51 is parallel to the right rack 52, and both the left rack 51 and the right rack 52 are parallel to the guide rail on the lifting plate 2. The left rack 51 and the right rack 52 are respectively arranged on both sides of the gear 50, and both are meshed with the gear 50. The sliding drive 5 is used to drive the left slide 3 to move, and the sliding drive 5 can be a cylinder or a linear motor. When the sliding drive 5 is started, the left slide 3 moves along the guide rail, the left rack 51 moves together with the left slide 3, the left rack 51 drives the gear 50 meshed with it to rotate, and the gear 50 drives the right rack 52 meshed with it to move, and the right slide 4 moves together with the right rack 52. The clamping mechanism can realize the simultaneous movement of the left slide 3 and the right slide 4 toward or away from each other through only one driving member, and adjust the distance between the left slide 3 and the right slide 4 to clamp or release the workpiece, and can be suitable for workpieces of different sizes.

[0011] The left slide 3 is provided with a left clamp 31, which can rotate relative to the left slide 3 and is located on the side of the left slide 3 close to the right slide 4. The right slide 4 is provided with a flip drive 6 and a right clamp 41, which can rotate relative to the right slide 4 and is located on the side of the right slide 4 close to the left slide 3. The flip gear 62 is installed on the rotating shaft of the right clamp 41, the flip rack 61 is meshed with the flip gear 62, and the flip drive 6 is connected with the flip rack 61 to drive the flip rack 61 to move up and down, and the flip drive 6 can be a cylinder or a linear motor. The left clamp 31 and the right clamp 41 are between the left slide 3 and the right slide 4 and at the same height position. The left clamp 31 has a left V-shaped opening with a V-shaped cross section, and the right clamp 41 has a right V-shaped opening with a V-shaped cross section, and the left V-shaped opening and the right V-shaped opening are positively opposite. The left V-shaped opening and the right V-shaped opening can better contact with the arc surface of the disc-shaped workpiece, and the clamping is more reliable. After the left clamping block 31 and the right clamping block 41 clamp the workpiece, the flip driving member 6 is started, the flip rack 61 moves, and the flip rack 61 drives the flip gear 62 to rotate. By controlling the moving distance of the flip rack 61, the flip gear 62 can be rotated 180 degrees, and the workpiece can be turned over.

[0012] See also Figure 1 and Figure 3 , two spring plungers 7 are provided on the left slide plate 3. The two spring plungers 7 are on a straight line passing through the center line of the rotating shaft of the left clamp 31, and are symmetrical about the center line of the rotating shaft of the left clamp. The spring plunger 7 includes a plunger head and a spring. The plunger head is pressed on the spring. In the absence of external force, the spring pushes the plunger head outward, and the plunger head extends to the longest distance outside; when the plunger head is pressed by external force, the plunger head compresses the spring and shrinks inward. A positioning plate 8 is provided on the rotating shaft of the left clamp 31. The positioning plate 8 has two positioning holes. The positions of the two positioning holes correspond to the positions of the two spring plungers 7. The two spring plungers 7 are each inserted into a positioning hole. After the left clamp 31 rotates 180 degrees, the two positioning holes exchange positions. The two spring plungers 7 are still each inserted into a positioning hole, so that the left clamp 31 can be kept in a horizontal position to ensure that the workpiece is rotated exactly 180 degrees when turning over.

[0013] The workpiece transmission line transfers the workpiece to the bottom of the lifting plate 2. The lifting plate 2 moves downward to a position where the left clamp block 31 and the right clamp block 41 are at the same height as the workpiece. Then the left slide plate 3 and the right slide plate 4 move toward each other. The left clamp block 31 and the right clamp block 41 clamp the workpiece together. Then the flip drive 6 is started to rotate the right clamp block 41 180 degrees. The workpiece and the left clamp block 31 also rotate 180 degrees together, turning the workpiece over. Then the left slide plate 3 and the right slide plate 4 move away from each other. The left clamp block 31 and the right clamp block 41 release the workpiece. The lifting plate 2 moves upward. The workpiece transmission line transfers the turned workpiece to the next process.

[0014] The workpiece turning device provided by the utility model controls the height position of the clamping mechanism by moving the lifting plate, and the left and right clamping blocks are clamped or loosened together by moving the left and right slide plates toward or away from each other. After clamping the workpiece, the right and left clamping blocks are rotated 180 degrees to turn the workpiece over. The entire turning work of the utility model is completed automatically by the machine, with a good degree of automation and high production efficiency.
