Description

Technical Field

[0001] The utility model relates to the technical field of clamping tools, in particular to a clamping tool with a flipping function. Background Art

[0002] Clamping tools are usually used to fix and clamp workpieces during manufacturing and processing for machining or other operations on the workpieces. The clamping tool disclosed in the publication number CN220240711U includes a fixing mechanism. The fixing mechanism includes a fixing base plate. One side of the fixing base plate is provided with a fixing plate. A first balance rod is arranged in the fixing base plate. A clamping mechanism is arranged on the first balance rod. The clamping mechanism includes a clamping plate. One side of the clamping plate is provided with a hand-tightening screw rod. Placing plates are arranged on both sides of the hand-tightening screw rod. This kind of clamping tool ensures the machining accuracy and quality, and can better meet the clamping requirements of different workpieces. It has the characteristics of high efficiency, precision and stability, and can significantly improve production efficiency and product quality. However, during the actual use of this kind of clamping tool, only one side of the workpiece can be machined. When it is necessary to machine the other side, the workpiece needs to be released from the limit, flipped and then fixed. This not only affects the work efficiency, but also increases the workload of workers during the process of flipping the workpiece and needs to be improved. Summary of the Utility Model

However, the present invention may also be implemented in other ways than those described herein. Therefore, the present invention is not limited to the specific embodiments of the following disclosure.

[0023] Embodiment 1

[0024] See also Figures 1-5, the present utility model provides a technical solution: a clamping tooling with a flipping function, including a fixed table 1. A side plate 2 is fixedly installed at the top of the fixed table 1. Threads are provided inside the side plate 2, and the threads provided inside the side plate 2 are meshed with the threads on the surface of the threaded rod A5. A hydraulic cylinder 3 is fixedly installed inside the fixed table 1. The output end of the hydraulic cylinder 3 is fixedly installed with a top plate 4. The top plate 4 is slidably connected to the side plate 2. The side plate 2 is threadedly connected with a threaded rod A5. One end of the threaded rod A5 is rotatably connected to a mounting plate 6. While the threaded rod A5 drives the mounting plate 6 to move, it can drive the motor 13 to move, so as to ensure that the upper and lower positions of the pulley A8 and the pulley B14 are consistent, facilitating the flipping of the workpiece. A guide rod 7 is fixedly installed on the side surface of the mounting plate 6. The guide rod 7 is slidably connected to the side plate 2. A pulley A8 is rotatably connected to the side surface of the mounting plate 6. The pulley A8 is connected to the pulley B14 through a belt 15. A frame plate 9 is fixedly installed on the side surface of the pulley A8. Threads are provided inside the frame plate 9, and the threads provided inside the frame plate 9 are meshed with the threads on the surface of the threaded rod B10. The frame plate 9 is threadedly connected with a threaded rod B10. The bottom end of the threaded rod B10 is rotatably connected to a pressing plate 11. When the threaded rod B10 is rotated, it will drive the pressing plate 11 to press down. Under the action of the pressure, it will drive the backing plate 17 to contact the workpiece, so as to press and limit the workpiece. A sliding plate 12 is fixedly installed at the top of the mounting plate 6. The sliding plate 12 is slidably connected to the side plate 2. A motor 13 is fixedly installed at the top of the sliding plate 12. The output end of the motor 13 is fixedly installed with a pulley B14. A belt 15 is sleeved on the surface of the pulley B14.

[0025] Embodiment 2

[0026] Please refer to Figures 3-5 , a T-shaped plate 16 is fixedly installed at the bottom end of the pressing plate 11. The T-shaped plate 16 is slidably connected to the T-shaped groove 18. A backing plate 17 is sleeved on the surface of the T-shaped plate 16. A T-shaped groove 18 is provided inside the backing plate 17. A limiting piece 19 is rotatably connected to the surface of the pressing plate 11. After the backing plate 17 is damaged after a long period of use, at this time, rotate the limiting piece 19 so that it no longer abuts against the backing plate 17, and then pull the backing plate 17 and slide it out along the T-shaped groove 18. At this time, the disassembly of the backing plate 17 is completed. Then, the backing plate 17 can be replaced. Continuing to use the backing plate 17 after it is damaged will result in a poor protection effect on the workpiece, and even the phenomenon of workpiece clamping damage due to excessive clamping force may occur.

[0027] Working principle: During operation, first adjust the distance between the two sets of frame plates 9 according to the shape and size of the workpiece. Rotate the threaded rod A5, and under the action of the thread, drive the mounting plate 6 to slide along the guide rod 7, so as to change the distance between the two sets of frame plates 9. After the adjustment is completed, place the workpiece inside the frame plates 9 and rotate the threaded rod B10. Under the action of the thread, it will drive the pressing plate 11 to press down. Under the action of the pressure, it will drive the backing plate 17 to contact the workpiece, so as to press and limit the workpiece. Then the workpiece can be processed. When the workpiece needs to be flipped, first start the hydraulic cylinder 3 and drive the top plate 4 to descend. Then start the motor 13 and drive the pulley B14 to rotate. Under the action of the belt 15, it will drive the pulley A8 to rotate, so as to drive the frame plates 9 and the workpiece to rotate together. When the workpiece is flipped 180 degrees, stop the motor 13 and start the hydraulic cylinder 3 to push the top plate 4 in the reverse direction to reset. At this time, the flipping work of the workpiece is completed. When the backing plate 17 is damaged after being used for a long time, rotate the limiting piece 19 at this time so that it no longer abuts against the backing plate 17. Then pull the backing plate 17 and slide it out along the T-shaped groove 18. At this time, the disassembly of the backing plate 17 is completed. During installation, first align the T-shaped groove 18 with the T-shaped block and slide it in. Then rotate the limiting piece 19 so that it abuts against the backing plate 17. At this time, the installation of the backing plate 17 is completed.

[0028] The above is only a preferred embodiment of the present invention, and it is not a limitation of the present invention in other forms. Any person skilled in the art may use the disclosed technical content to make changes or modifications into equivalent embodiments with equivalent changes and apply them to other fields. However, as long as it does not depart from the technical solution content of the present invention, any simple modification, equivalent change and modification made to the above embodiments based on the technical essence of the present invention still fall within the protection scope of the technical solution of the present invention.
