[0015] The present invention will be further described below with reference to the accompanying drawings.

[0016] like Figs. 1 to 3As shown, a machine tool workpiece flipping device includes an X-axis moving mechanism 2 disposed on one side of the machine tool bed 1, a Y-axis moving mechanism 3 disposed on the X-axis moving mechanism 2, a Z-axis moving mechanism 4 disposed on the Y-axis moving mechanism 3, a rotating mechanism 5 disposed on the Z-axis moving mechanism 4, and a clamping mechanism 6 disposed on the rotating mechanism 5. The X-axis moving mechanism 2 includes a first slide rail 21 disposed on the bed 1, a first slide block 22 slidably engaged with the first slide rail 21, and a first drive assembly for driving the first slide block 22; the first slide rail 21 is disposed on the side of the bed 1 and arranged along the length direction of the bed 1, and can integrate various processing equipment on the bed 1, and transport workpieces in a continuous operation through the X-axis moving mechanism 2; the first drive assembly includes a first nut disposed on the first slide block 22, a first screw engaged with the first nut, and a first motor for driving the first screw. The Y-axis moving mechanism 3 includes a second slide rail 33 mounted on a first slide block 22, a second slide block 32 slidably engaged with the second slide rail 33, and a second drive assembly 33 for driving the second slide block 32. The second drive assembly 33 includes a second nut mounted on the second slide block 32, a second screw engaged with the second nut, and a second motor for driving the second screw. The Z-axis moving mechanism 4 includes a third slide rail 43 mounted on the second slide block 32, a third slide block 42 slidably engaged with the third slide rail 43, and a third drive assembly 41 for driving the third slide block 42. The third drive assembly 41 includes a third nut mounted on the third slide block 42, a third screw engaged with the third nut, and a third motor for driving the second screw. The rotating mechanism 5 includes a rotating shaft pivotally connected to the third slide block 42, a fourth drive assembly for driving the rotating shaft, and a rotating seat 61 connected to the rotating shaft. The fourth drive assembly includes a speed reducer and a fourth motor for driving the speed reducer. The clamping mechanism 6 includes a fourth slide rail 63 mounted on a rotating base 61, two chucks 62 that slide in cooperation with the fourth slide rail 63, and a hydraulic cylinder that drives the two chucks 62 to move in opposite directions. The two chucks 62 move synchronously and have a centering function, which can center and clamp the workpiece for more accurate positioning.

[0017] The principle of this invention is as follows: When the workpiece is being processed, the chuck is positioned on one side of the bed 1, away from the processing area, so that the chuck will not interfere with the processing of the workpiece. When it is necessary to flip the workpiece, the X-axis moving mechanism 2 does not move, while the Y-axis moving mechanism 3 moves and drives the Z-axis moving mechanism 4 and the clamping mechanism 6 to move towards the workpiece. The clamping mechanism 6 flips the workpiece under the same coordination of the Y-axis moving mechanism 3, the Z-axis moving mechanism 4, and the rotating mechanism 5. For example, the workpiece can be flipped 180 degrees, so that the bottom surface is flipped to the processing position. After the workpiece is processed, the clamping mechanism 6 can clamp the workpiece again and transport it to the next station through the X-axis moving mechanism 2. Using a robotic arm for clamping and transport can reduce the secondary positioning of the workpiece, facilitate automated processing and production, and help improve production efficiency.
