In addition, the terms "first" and "second" are only used for descriptive purposes and cannot be construed as indicating or implying relative importance.

[0028] In the description of the present invention, it should be noted that unless otherwise clearly specified and limited, the terms "installation", "provided with", "sheathed / connected", "connection", etc. should be understood in a broad sense. For example, "connection" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the internal communication of two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0029] Example, referring to Figures 1 to 6 , a precision processing device for automotive metal castings, including a multi-faceted cutting device controlled by a robotic arm and a casting treatment table 1. The robotic arm is a prior art and will not be elaborated in detail here. It can control the multi-faceted cutting device to synchronously cut the castings distributed around the casting gate.

[0030] The casting processing table 1 is connected with a carrying and processing disc 2 through a rotating motor. A rotating outer cylinder 3 is fixedly connected to the carrying and processing disc 2. A grinding layer for grinding the cutting surface of the casting is arranged on the inner side wall of the rotating outer cylinder 3. The arrangement of the grinding layer can, when the rotating outer cylinder 3 is driven by the rotating motor to rotate, come into contact with the casting on the installation sleeve 6, achieving the effect of automatically grinding the cutting surface of the casting.

[0031] A clamping member 4 is arranged at the center position of the carrying and processing disc 2. The clamping member 4 is a prior art and can clamp the casting column formed by the casting gate of the casting, ensuring that the carrying and processing disc 2 can drive the casting to rotate during rotation, and effectively removing the residual mold sand on the casting during rotation;

[0032] An assembly and separation ring body 5 is rotatably arranged on the carrying and processing disc 2. A plurality of installation sleeves 6 are detachably installed in the assembly and separation ring body 5. Further, an installation port 17 adapted to the installation sleeve 6 is opened on the assembly and separation ring body 5. The installation sleeve 6 is installed in the installation port 17 and is in rotational contact with the installation port 17.

[0033] A casting-by-casting picking-up component is arranged in the installation sleeve 6. The casting-by-casting picking-up component includes a supporting vertical plate 10 arranged in the installation sleeve 6. The supporting vertical plate 10 is connected with a magnetic repulsion disc 11 through an elastic resetting member. Further, the elastic resetting member includes a reset column 23 fixedly connected to the magnetic repulsion disc 11. The reset column 23 penetrates the side wall of the supporting vertical plate 10 and extends inward, and is fixedly connected with a reset disc 24. The reset disc 24 is connected with the side wall of the supporting vertical plate 10 through a sleeve reset spring sleeved on the reset column 23. An electromagnetic plate 25 is arranged on the supporting vertical plate 10, and the magnetic repulsion disc 11 repels the electromagnetic plate 25 magnetically.

[0034] It should be noted that when the electromagnetic plate 25 is turned on, the magnetic repulsion force generated by it on the magnetic repulsion disc 11 is much greater than the reset force of the sleeve reset spring. Therefore, when the electromagnetic plate 25 is turned on, the magnetic repulsion disc 11 will be driven to extend forward away from the supporting vertical plate 10. Its extension will contact the transmission shaft fork casting, and the inserting and picking-up member arranged on the magnetic repulsion disc 11 will be locked corresponding to the structure on the transmission shaft fork.

[0035] An inserting and picking-up member is fixedly connected to the end of the magnetic repulsion disc 11. Further, the inserting and picking-up member includes an inserting head 26. A telescopic opening is opened in the inserting head 26. Oppositely arranged T-shaped clamping blocks 27 are slidably arranged in the telescopic opening. Adjacent two T-shaped clamping blocks 27 are connected through a resisting spring. The side walls on both sides of the T-shaped clamping block 27 are both arc-shaped.

[0036] It should be noted that during the forward movement of the T-shaped clamping block 27, the arc surface thereof enables the T-shaped clamping block 27 to be easily inserted into the transmission shaft fork casting, forming a clamping connection with the transmission shaft fork casting. Thus, when the magnetic repulsive force fails, the elastic reset member generates an outward traction force on the transmission shaft fork casting, so as to realize outward traction at the moment when the casting is cut and broken, avoiding the situation that the casting drops and causes quality damage and the cut casting affects subsequent cutting.

[0037] A lifting hydraulic cylinder 9 for lifting and controlling the ring cover 8 is arranged on the casting processing table 1. The lifting hydraulic cylinder 9 is a prior art and will not be elaborated here. The tops of a plurality of mounting sleeves 6 are connected with a control ring cover 8 through a rotating connection seat 7. An adjusting member for controlling the rotation of the mounting sleeves 6 is arranged on the control ring cover 8. Further, the adjusting member includes an adjusting motor 18 arranged on the control ring cover 8. A linkage gear ring 19 is rotatably arranged on the control ring cover 8. The output end of the adjusting motor 18 is fixedly connected with an adjusting master control gear 20 meshed with the linkage gear ring 19. The top of the mounting sleeve 6 is fixedly connected with an inner shaft body 21. The inner shaft body 21 penetrates through the rotating connection seat 7 and extends upward, and is fixedly connected with an adjusting gear 22. The adjusting gear 22 is meshed with the linkage gear ring 19.

[0038] The advantage of adopting the above structure is that it can realize the synchronous rotation of a plurality of inner shaft bodies 21 through the control of the adjusting member, so as to control the rotation of the mounting sleeves 6, and drive the transmission shaft fork casting originally inside the assembled separating ring body 5 to rotate to face the outside, thus facilitating the grinding treatment of its cutting surface.

[0039] The multi-faceted cutting device includes a mounting seat 12 connected to the robotic arm. The mounting seat 12 is connected to a control seat 13 through a plurality of mounting columns. The outer side wall of the control seat 13 is connected to a cutting cutter head 15 through a U-shaped frame 14. A cutting drive motor 16 is arranged on the control seat 13. The cutting drive motor 16 is connected to a plurality of cutting cutter heads 15 through a drive device.

[0040] Further, the drive device includes a drive gear 28 connected to the output end of the cutting drive motor 16. The cutting cutter head 15 is rotatably connected to the U-shaped frame 14 through a cutting rotating shaft 29. A worm gear 30 is fixedly connected to the end of the cutting rotating shaft 29. The worm gear 30 is meshed with a worm 31. The worm 31 is fixedly connected with a vertical rotating shaft. The vertical rotating shaft is rotatably connected with the control seat 13. The vertical rotating shaft penetrates through the control seat 13 and extends upward, and is connected with a direct drive gear 32 meshed with the drive gear 28. Through the setting of the drive device, it can synchronously drive a plurality of cutting cutter heads 15 located on multiple sides, enabling them to simultaneously cut a plurality of castings around the runner, significantly improving the casting segmentation efficiency.

[0041] When the present invention processes the castings taken out from the sand mold, the casting columns formed by the casting gates of multiple castings are installed at the clamping member 4, and the castings are clamped and fixed by the clamping member 4. By rotating the carrying processing disk 2, the castings are driven to rotate by the clamping member 4. The high-speed rotating castings will cause the sand adhered to them to fall off centrifugally, thereby realizing the cleaning of the sand on the castings and avoiding the influence of the presence of sand on the cutting effect of the cutting tool disk 15 on the castings in the subsequent process;

[0042] After the cleaning of the sand is completed, when ensuring that the casting picking components installed in the installation sleeve 6 face the castings one by one, the electromagnetic plate 25 is controlled to be turned on. Under the action of magnetic repulsion force, the magnetic repulsion disk 11 will be driven to approach the castings, and the inserted picking parts arranged thereon will be locked corresponding to the structures on the castings (in this solution, the transmission shaft fork is taken as an example for design). At this time, the power supply of the electromagnetic plate 25 is cut off, and the magnetic repulsion disk 11 will generate an outward traction force on the castings under the action of the sleeved return spring, thereby realizing the fixation of the castings during the cutting process.

[0043] The multi-faceted cutting device is controlled by the robotic arm to move downward, and the castings are gradually cut one by one from top to bottom. At the moment when the casting is cut off, under the action of the traction force, the cut-off casting will be driven to move by the inserted picking parts, so as to move away from the cutting point and avoid secondary damage to the casting caused by the cutting tool. During the process of cutting one by one, the inserted picking parts will realize the traction and fixation of the castings one by one;

[0044] After the cutting is completed, the motor 18 is controlled to drive the casting in the installation sleeve 6 to be flipped 180 degrees so that it faces the outside. At this time, the carrying processing disk 2 connected to the rotating motor is controlled to rotate, driving the grinding layer arranged on the inner wall of the rotating outer cylinder 3 to rotate at a high speed. The electromagnetic plate 25 is controlled to be turned on, and pressure is applied to the casting so that its cutting surface can closely adhere to the grinding layer for rapid grinding, realizing the effective treatment of the cutting surface and ensuring the quality of the cut castings.

[0045] The above is only the preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and inventive concept of the present invention, makes equivalent substitutions or changes, and should be covered within the protection scope of the present invention.
