Specific implementation manner
[0018] Next, in combination with the accompanying drawings and specific implementation manners, the present utility model will be further described. It should be noted that, on the premise of no conflict, the following-described embodiments or technical features can be combined arbitrarily to form new embodiments.
[0019] Embodiment 1: Please refer to Figure 1 - Figure 3 , a clamping and flipping device for mechanical processing in this embodiment, includes a column 1 and a fixing block 2. The bottom of the column 1 is fixedly connected with a base 3. A motor 4 is arranged outside the column 1. One end of the motor 4 is fixedly connected with a rotating shaft 5. The rotating shaft 5 is rotatably connected to the top of the column 1. One end of the rotating shaft 5 is fixedly connected to one side of the fixing block 2. The fixing block 2 is located inside the column 1. A handwheel 6 is arranged on the top of the fixing block 2. The bottom of the handwheel 6 is fixedly connected with a threaded rod 7. The bottom of the threaded rod 7 is threadedly connected with a movable clamping block 8. A groove is machined on the top of one side of the fixing block 2. One end of the movable clamping block 8 is movably connected inside the groove. A fixed clamping block 9 is fixedly connected to the bottom of one side of the fixing block 2. A workpiece 18 is arranged between the movable clamping block 8 and the fixed clamping block 9;
[0020] Among them, when it is necessary to process the workpiece 18, the workpiece 18 is placed between the movable clamping block 8 and the fixed clamping block 9, and then the handwheel 6 is rotated. The handwheel 6 will drive the threaded rod 7 to rotate. The threaded rod 7 will drive the movable clamping block 8 to move downward, so that the bottom of the movable clamping block 8 contacts the top surface of the workpiece 18, thereby fixing the workpiece 18 through the fixed clamping block 9;
[0021] Secondly, when it is necessary to flip the workpiece 18, the motor 4 is started. The motor 4 will drive the rotating shaft 5 to rotate. The rotating shaft 5 will drive the fixing block 2 to rotate. The fixing block 2 will drive the movable clamping block 8 and the fixed clamping block 9 to rotate, so that the movable clamping block 8 and the fixed clamping block 9 drive the workpiece 18 to rotate and flip, which is convenient for processing other surfaces of the workpiece 18;
[0022] Further, one end of the rotating shaft 5 is fixedly connected with a first limiting ring 10, and the other end of the rotating shaft 5 is fixedly connected with a second limiting ring 11. The first limiting ring 10 is located outside the column 1, and the second limiting ring 11 is located inside the column 1. When the rotating shaft 5 rotates, it will drive the first limiting ring 10 and the second limiting ring 11 to rotate. The first limiting ring 10 and the second limiting ring 11 rotate on both sides of the column 1 respectively. Thus, by providing the first limiting ring 10 and the second limiting ring 11, the rotation of the rotating shaft 5 can be limited to prevent the rotating shaft 5 from detaching from the top of the column 1;
[0023] Further, two sliders 16 are fixedly connected to both ends of the movable clamping block 8. A sliding groove 17 is machined inside the groove of the fixed block 2. The slider 16 is movably connected inside the sliding groove 17. When the threaded rod 7 rotates, it will drive the movable clamping block 8 to move up and down. The movable clamping block 8 will drive the slider 16 to move up and down, causing the slider 16 to move up and down along the inside of the sliding groove 17. By providing the sliding groove 17, the movement of the movable clamping block 8 can be limited to prevent the movable clamping block 8 from detaching from the inside of the groove of the fixed block 2;
[0024] Further, a hydraulic rod 12 is provided on the top of the base 3. The top of the hydraulic rod 12 is fixedly connected with a support plate 13. When it is necessary to flip the workpiece 18, first start the hydraulic rod 12, so that the top of the hydraulic rod 12 drives the support plate 13 to move downward, thereby causing the support plate 13 to disengage from the bottom of the workpiece 18, and then facilitating the flipping of the workpiece 18. After the workpiece 18 is flipped, the hydraulic rod 12 will push the support plate 13 to move upward to contact the bottom of the workpiece 18 to provide support;
[0025] Further, a plurality of movable rods 14 are movably connected to the periphery of the support plate 13. The bottom of the movable rod 14 is fixedly connected with the top of the column 1. The top of the movable rod 14 is fixedly connected with a limiting block 15. The limiting block 15 is located on the top of the support plate 13. When the hydraulic rod 12 drives the support plate 13 to move up and down, the support plate 13 will move downward along the outside of the movable rod 14. The movable rod 14 will limit the movement of the support plate 13 to keep the support plate 13 in a stable state when it moves up and down. By providing the limiting block 15, the support plate 13 can be prevented from detaching from the outside of the movable rod 14.
[0026] Working principle: Place the workpiece 18 between the movable clamping block 8 and the fixed clamping block 9, and then rotate the handwheel 6. The threaded rod 7 will drive the movable clamping block 8 to move downward, so that the movable clamping block 8 and the fixed clamping block 9 fix the workpiece 18. When it is necessary to flip the workpiece 18, start the hydraulic rod 12, so that the top of the hydraulic rod 12 drives the support plate 13 to move downward, so that the support plate 13 is disengaged from the bottom of the workpiece 18. Then start the motor 4, the motor 4 will drive the rotating shaft 5 to rotate, the rotating shaft 5 will drive the fixed block 2 to rotate, the fixed block 2 will drive the movable clamping block 8 and the fixed clamping block 9 to rotate, so that the movable clamping block 8 and the fixed clamping block 9 drive the workpiece 18 to rotate and flip, which is convenient for machining other surfaces of the workpiece 18.

Any non-substantial changes and substitutions made by those skilled in the art based on the present invention belong to the scope of protection required by the present invention.
