[0001] This utility model relates to the technical field of multi-axis machining devices, and in particular to an automatic rotating clamping device for multi-axis machining. Background Technology

[0002] In today's industrial manufacturing field, multi-axis machining technology, with its high precision, high efficiency, and ability to complete the machining of complex parts on multiple sides in one go, has become an indispensable key technology in high-end manufacturing industries such as aerospace, automobile manufacturing, and precision instruments.

[0003] Most existing multi-axis machining clamping devices lack efficient and convenient automatic flipping mechanisms. When multi-face machining of a workpiece is required, the operator usually needs to stop the machine, manually disassemble the workpiece, flip it to the required machining surface, and then reinstall and reposition and clamp it. This process is not only tedious and complicated, requiring the operator to have rich experience and skilled expertise, but also time-consuming, which greatly reduces machining efficiency. Utility Model Content

[0004] The technical problem to be solved by this utility model is that the existing technology has the disadvantage that it cannot achieve automatic flipping, and each flipping operation may take a long time, which seriously affects the production progress. To this end, we propose an automatic flipping clamping device for multi-axis machining.

[0005] To achieve the above objectives, this application adopts the following technical solution: an automatic rotating clamping device for multi-axis machining, comprising a multi-axis machining device body, a machining table mounted on the top of the multi-axis machining device body, adjusting arms fixedly connected to both sides of the machining table, a flipping drive mechanism mounted on the side of the adjusting arm away from the machining table, an adjusting column mounted on the side of the adjusting arm away from the flipping drive mechanism, a rotating column rotatably connected inside the adjusting column, a clamping arm provided inside the rotating column, adjusting grooves opened at both ends of the rotating column, adjusting blocks slidably connected inside the adjusting grooves, a plug rod fixedly connected to the side of the adjusting block away from the adjusting column, a plurality of plug holes provided inside the clamping arm, and arc-shaped blocks fixedly connected to both ends inside the adjusting column.

[0006] Preferably, the size of the plug rod is adapted to the size of the socket, and the surface of the plug rod is inserted into the interior of the socket.

[0008] Preferably, both ends of the adjusting groove are provided with sliding grooves, and both ends of the adjusting block are fixedly connected with sliders, the surface of the sliders being slidably connected to the inside of the sliding groove.

[0009] Preferably, both ends of the rotating column are provided with shrinkage grooves, and an insertion block is slidably connected inside the shrinkage groove. A return spring is fixedly connected to the side of the insertion block near the inside of the shrinkage groove, and the side of the return spring away from the insertion block is fixedly connected to the inside of the shrinkage groove. Both ends of the adjusting column are provided with insertion holes.

[0010] Preferably, guide grooves are provided at both ends of the shrinkage groove, and guide rings are fixedly connected to both ends of the insertion block, with the surface of the guide rings slidingly connected to the interior of the guide grooves.

[0011] Preferably, the inner wall of the adjusting column is provided with two annular grooves, and two annular blocks are fixedly connected to the outer diameter surface of the rotating column.

[0012] The technical effects and advantages of this utility model are as follows:

[0013] In this invention, the operator rotates the rotating column, causing the adjusting block and the insert rod to move synchronously.

At the same time, the limit of the clamping arm is also released. The operator stretches the clamping arm, adjusts it to the appropriate position, and then inserts the insert rod into the insertion hole to reset it. This allows the operator to flip and clamp workpieces of different specifications. Attached Figure Description

[0020] The present invention will now be described in further detail with reference to the accompanying drawings and preferred embodiments. These drawings are simplified schematic diagrams, which only illustrate the basic structure of the present invention in a schematic manner, and therefore only show the components related to the present invention.

[0021] Reference Figures 1-5 As shown, this utility model provides a technical solution: an automatic rotating clamping device for multi-axis machining, including a multi-axis machining device body 1, a machining table 2 mounted on the top of the multi-axis machining device body 1, adjusting arms 3 fixedly connected to both sides of the machining table 2, a flipping drive mechanism 4 mounted on the side of the adjusting arm 3 away from the machining table 2, an adjusting column 5 mounted on the side of the adjusting arm 3 away from the flipping drive mechanism 4, a rotating column 6 rotatably connected inside the adjusting column 5, a clamping arm 7 provided inside the rotating column 6, adjusting grooves 8 opened at both ends of the rotating column 6, adjusting blocks 9 slidably connected inside the adjusting grooves 8, and a plug rod 10 fixedly connected to the side of the adjusting block 9 away from the adjusting column 5. The clamping arm 7 has several insertion holes 11 inside. Both ends of the adjusting column 5 are fixedly connected to arc blocks 12. The operator rotates the rotating column 6, which drives the adjusting block 9 and the insertion rod 10 to move synchronously. At the same time, the contact between the adjusting block 9 and the arc block 12 is canceled. Under the action of the rebound force of the storage spring 13, the adjusting block 9 is quickly pushed, which drives the insertion rod 10 to release the limit between it and the insertion hole 11. At the same time, the limit of the clamping arm 7 is also released. The operator stretches the clamping arm 7, adjusts it to the appropriate position, and then inserts the insertion rod 10 into the insertion hole 11 to reset it. This allows the operator to flip and clamp workpieces of different specifications.

[0022] Reference Figure 3 As shown in this embodiment: the size of the insertion rod 10 is adapted to the size of the insertion hole 11, and the surface of the insertion rod 10 is inserted into the interior of the insertion hole 11. By adapting the size of the insertion rod 10 to the size of the insertion hole 11, the insertion rod 10 can be stably inserted into the interior of the insertion hole 11, effectively preventing the insertion rod 10 from falling off or shaking during use, enhancing the stability and reliability of the overall structure. At the same time, this insertion method facilitates quick installation and disassembly by users, improving work efficiency.

[0023] Reference Figure 3As shown in this embodiment: a storage spring 13 is fixedly connected to the side of the adjusting block 9 near the insertion rod 10, and the side of the storage spring 13 away from the adjusting block 9 is fixedly connected to the inside of the adjusting groove 8. When the operator pushes the adjusting block 9 with the arc-shaped block 12, the adjusting block 9 compresses the storage spring 13 to store force, and drives the insertion rod 10 to be inserted into the insertion hole 11 for fixation. When the operator releases the restriction of the arc-shaped block 12, under the action of the rebound force of the storage spring 13, the adjusting block 9 will quickly move in the opposite direction, causing the insertion rod 10 to release the restriction between itself and the insertion hole 11.

[0024] Reference Figure 3 and Figure 4 As shown in this embodiment: both ends of the adjusting groove 8 are provided with sliding grooves 14, and both ends of the adjusting block 9 are fixedly connected with sliders 15. The surface of the sliders 15 is slidably connected to the inside of the sliding groove 14. When the operator moves the adjusting block 9, the adjusting block 9 drives the sliders 15 to slide inside the sliding groove 14. Through the above settings, the stability of the movement of the adjusting block 9 is improved, and the phenomenon of the adjusting block 9 deviating or shaking during the movement is avoided, ensuring the normal operation of the device. At the same time, the sliders 15 can also play a certain guiding role during the sliding inside the sliding groove 14, making the movement of the adjusting block 9 smoother and more stable.

[0025] Reference Figure 3 and Figure 4 As shown in this embodiment: both ends of the rotating column 6 are provided with shrinkage grooves 16, and an insertion block 17 is slidably connected inside the shrinkage groove 16. A return spring 18 is fixedly connected to the side of the insertion block 17 near the inside of the shrinkage groove 16, and the side of the return spring 18 away from the insertion block 17 is fixedly connected to the inside of the shrinkage groove 16. Both ends of the adjusting column 5 are provided with insertion holes 19. When the operator fully inserts the insertion rod 10 into the insertion hole 11, the return spring 18 pushes the insertion block 17 into the insertion hole 19 for fixing by the setting between the position of the insertion block 17 and the insertion hole 19. Through the above setting, the rotating column 6 is prevented from rotating inside the adjusting column 5.

[0026] Reference Figure 3 and Figure 4 As shown in this embodiment: guide grooves 20 are provided at both ends of the shrinkage groove 16, and guide rings 21 are fixedly connected to both ends of the insertion block 17. The surface of the guide ring 21 is slidably connected to the inside of the guide groove 20. When the operator moves the insertion block 17, the insertion block 17 drives the guide ring 21 to slide inside the guide groove 20. Through the above settings, the movement of the insertion block 17 can be made more stable, avoiding the shaking or displacement of the insertion block 17 during the movement, thus improving the stability and reliability of the overall structure.

[0027] Reference Figure 3 and Figure 4 As shown in this embodiment: the inner wall of the adjusting column 5 is provided with two annular grooves 22, and two annular blocks 23 are fixedly connected to the outer diameter surface of the rotating column 6. When the operator rotates the rotating column 6, the rotating column 6 drives the annular grooves 22 to rotate inside the annular blocks 23. Through the above settings, the stable rotation of the rotating column 6 is achieved, avoiding the phenomenon of the rotating column 6 deviating or shaking during the rotation, thereby improving the stability and accuracy of the rotating column 6.

[0028] Working principle: By rotating the rotating column 6, the operator moves the adjusting block 9 and the insertion rod 10 synchronously, simultaneously canceling the contact between the adjusting block 9 and the arc-shaped block 12. Under the rebound force of the storage spring 13, the adjusting block 9 is quickly pushed, causing it to release the insertion rod 10 from the limiting position between it and the insertion hole 11. At the same time, the limiting position of the clamping arm 7 is also released. The operator stretches the clamping arm 7, adjusts it to the appropriate position, and then inserts the insertion rod 10 into the insertion hole 11 to reset it. This allows the operator to flip and clamp workpieces of different specifications. The matching size of the insertion rod 10 with the size of the insertion hole 11 ensures that the insertion rod 10 can be stably clamped. The rod 10 is firmly inserted into the socket 11, effectively preventing it from falling off or shaking during use, thus enhancing the stability and reliability of the overall structure. This insertion method also facilitates quick installation and disassembly, improving work efficiency. When the operator pushes the adjusting block 9 with the arc-shaped block 12, the adjusting block 9 compresses the storage spring 13, storing force and driving the rod 10 into the socket 11 for fixation. When the operator releases the restriction of the arc-shaped block 12, the adjusting block 9 quickly moves in the opposite direction under the rebound force of the storage spring 13, releasing the rod 10 from the restriction between it and the socket 11. When in motion, the adjusting block 9 drives the slider 15 to slide inside the slide groove 14. This design improves the stability of the adjusting block 9's movement, preventing it from shifting or wobbling during movement and ensuring the normal operation of the device. Simultaneously, the slider 15's sliding within the slide groove 14 also provides guidance, making the adjustment block 9's movement smoother and more stable. When the operator fully inserts the insertion rod 10 into the insertion hole 11, the return spring 18 pushes the insertion block 17 into the insertion hole 19 for fixation, thanks to the positioning of the insertion block 17 and the insertion hole 19. This design prevents the rotating column 6 from shifting during adjustment. The column 5 rotates internally. When the operator moves the insertion block 17, the insertion block 17 drives the guide ring 21 to slide inside the guide groove 20. This setting makes the movement of the insertion block 17 more stable, avoiding wobbling or deviation during the movement, thus improving the stability and reliability of the overall structure. When the operator rotates the rotating column 6, the rotating column 6 drives the annular groove 22 to rotate inside the annular block 23. This setting achieves stable rotation of the rotating column 6, avoiding deviation or wobbling during the rotation, thus improving the stability and accuracy of the rotating column 6.
