[0028] The base 3 can be used to support the bottom of the entire tooling, increasing the contact area between the bottom of the tooling and the placement position. The long foot bolts are installed by the fixing block 5 to improve the stability of the entire tooling when in use. The arc-shaped auxiliary part 12 is used to support the bottom of the reinforcement member 4, which can avoid the bottom of the reinforcement member 4 from being suspended in the air, thereby improving the stability of the reinforcement member 4 when flipping. The side of the bevel gear 2 10 away from the reinforcement member 4 is rotatably connected to the vertical plate 24. The vertical plate 24 can be used to support one side of the reinforcement member 4. At the same time, the base 3 can be used to support the bottom of the motor 7, so that the motor 7 can drive the bevel gear 6 to rotate, and then the rotation of the bevel gear 6 drives the bevel gear 2 10 to rotate, thereby realizing the flipping adjustment of the reinforcement member 4. The two ends of the inclined rod 18 are respectively connected to the support plate 2 and the reinforcement member 4, which can reinforce the connection between the support plate 2 and the reinforcement member 4, thereby improving the stability of the support plate 2 when in use. The positioning plate 19 can assist the connection between the support plate 2 and the support member 11 to avoid the shaking of the support member 11 during the flipping process.

[0029] Embodiment 2: Figure 1 - Figure 5 As shown, a clamping plate 20 is clamped on one side of the support plate 2, and a clamping plate 21 is provided on one side of the clamping plate 20. One side of the clamping plate 21 is clamped and connected with the support plate 2. A guide groove 22 is provided on one side of the support plate 2. A calibration plate 16 is inserted through the inside of the guide groove 22. The calibration plate 16 is slidingly connected to the support plate 2. The calibration plate 16 is connected to the threaded rod 17 through a thread. One end of the threaded rod 17 is rotatably connected to a mounting block. One side of the mounting block is fixedly connected to the support plate 2. An auxiliary part 23 is fixedly connected to one side of the inner wall of the support member 11. A connecting member 3 15 is fixedly connected to one side of the auxiliary part 23. One end of the connecting member 3 15 is hinged to a limiting part 2 8.

[0030] One side of the limit member 2 8 is slidably connected to the limit member 1, and one side of the limit member 1 and the limit member 2 8 are provided with positioning holes, and the limiting pins are inserted in the positioning holes. One side of the limit member 2 8 is hinged with a connecting member 13, and one end of the connecting member 13 is overlapped with a connecting member 2 14, and the connecting member 2 14 is Y-shaped. One side of the connecting member 2 14 is hinged to the connecting member 3 15, and the other end of the connecting member 2 14 is hinged to the end of the hydraulic cylinder 9, one side of the hydraulic cylinder 9 is hinged to the inner wall of the support member 11, and one end of the hydraulic cylinder 9 is fixedly connected to the inner wall of the reinforcement member 4.

[0031] The clamping plate 1 20 and the clamping plate 2 21 can be used to preliminarily limit the placement position of the workpiece on the top of the support plate 2. The rotation of the threaded rod 17 can drive the calibration plate 16 to move, changing the use position of the calibration plate 16. When the calibration plate 16 moves, the guide groove 22 can be used to guide the movement of the calibration plate 16, so that one side of the calibration plate 16 contacts the workpiece, thereby improving the limiting effect of the workpiece on the top of the support plate 2 and reducing the position deviation or shaking of the workpiece. The connection between one end of the hydraulic cylinder 9 and the connection member 3 15 can be realized through the connection member 2 14. , the upward rotation range of the limiter 2 8 can be limited by the connecting member 13, the connection between the support member 11 and the connecting member 3 15 can be realized by using the auxiliary member 2 23, one side of the support member 11 is hinged with the hydraulic cylinder 9, which is convenient for the rotation of the support member 11 on one side of the hydraulic cylinder 9, and then the synchronous adjustment with the rotation of the limiter 2 8 and the limiter 1 1 can be realized, the reinforcement member 4 can be used to support the bottom of the hydraulic cylinder 9, which is convenient for using the drive of the hydraulic cylinder 9 to realize the position adjustment of the limiter 1 1, and the limiter 1 clamps the top of the workpiece;

[0032] At the same time, the sliding connection between the limit member 1 and the limit member 2 8 can adjust the extension length of the limit member 1, and then adjust the contact area between the bottom of the limit member 1 and the top of the workpiece. When the right end of the limit member 1 is separated from the limit member 2 8, the limit member 1 can be disassembled, which is convenient for the rapid replacement of limit members 1 of different shapes, thereby improving the applicability of the entire tooling.

[0033] The method of using and working principle of the device are as follows: first, when the entire tooling is in use, the workpiece to be clamped is placed on the support plate 2, and the side walls of the workpiece are overlapped with the clamping plate 1 20 and the clamping plate 2 21 respectively. Then, the threaded rod 17 is rotated at the bottom of the support plate 2 to drive the calibration plate 16 to move to the side close to the workpiece to achieve the position calibration of the workpiece. Then, the end of the hydraulic cylinder 9 is contracted. At this time, the connecting member 2 14 is driven by the hydraulic cylinder 9 to drive the support member 11 to rotate with the connection point between the support member 11 and the hydraulic cylinder 9 as the axis. When the support member 11 rotates, the limiting member 2 8 is driven to rotate to the side close to the workpiece through the hinge connection between the connecting member 3 15 and the limiting member 2 8, so that the bottom of the limiting member 1 is pressed on the workpiece to achieve the clamping limit of the workpiece.

[0034] If the workpiece needs to be turned over, the positioning plate 19 is engaged on one side of the support member 11, and then the positioning plate 19 is connected to the bottom of the support plate 2 by bolts, and then the motor 17 drives the bevel gear 16 to rotate, and the bevel gear 16 drives the bevel gear 2 10 to rotate, so that the bevel gear 2 10 and the reinforcement member 4 rotate on one side of the vertical plate 24, changing the use direction of the reinforcement member 4 and the processing position of the workpiece;

[0035] Move the limit piece 1 to one side of the limit piece 2 8 to increase the extension length of the limit piece 1 1 , and then insert the pins into the positioning holes of the limit piece 1 and the limit piece 2 8 to fix them, so as to adjust the use length of the limit piece composed of the limit piece 1 and the limit piece 2 8 .
