For example, "connected" 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 a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0020] Example, see Figures 1 to 6 A precision processing device for automobile metal casting processing includes a multi-faceted cutting device controlled by a mechanical arm and a casting processing table 1. The mechanical arm is a prior art and will not be described in detail here. It can realize the control of the multi-faceted cutting device and synchronously cut the castings distributed around the casting port through the multi-faceted cutting device; The casting processing table 1 is connected to a carrying processing disk 2 through a rotating motor, and a rotating outer vertical cylinder 3 is fixedly connected to the carrying processing disk 2. The inner wall of the rotating outer vertical cylinder 3 is provided with a grinding layer for grinding the cut surface of the casting. The grinding layer is provided so that when the rotating outer vertical cylinder 3 is driven by the rotating motor to rotate, it can come into contact with the casting on the mounting sleeve 6, thereby achieving the effect of automatically grinding the cut surface of the casting.

[0021] A clamping member 4 is provided at the center of the carrying and processing plate 2. The clamping member 4 is a prior art and can clamp the casting column formed by the pouring port of the casting, and can ensure that the carrying and processing plate 2 can drive the casting to rotate during the rotation process, and during the rotation process, the residual molding sand on the casting can be effectively removed; An assembly separation ring body 5 is rotatably arranged on the supporting processing disk 2, and a plurality of installation sleeves 6 are detachably installed in the assembly separation ring body 5. Furthermore, an installation opening 17 adapted to the installation sleeve 6 is opened on the assembly separation ring body 5, and the installation sleeve 6 is installed in the installation opening 17 and is in rotational contact with the installation opening 17.

[0022] A casting one-by-one picking-up assembly is arranged in the mounting sleeve 6, and the casting one-by-one picking-up assembly includes a supporting vertical plate 10 arranged in the mounting sleeve 6, and the supporting vertical plate 10 is connected to a magnetic repulsion disk 11 through an elastic reset member. Further, the elastic reset member includes a reset column 23 fixedly connected to the magnetic repulsion disk 11, the reset column 23 extends inwardly through the side wall of the supporting vertical plate 10, and is fixedly connected to a reset disk 24, and the reset disk 24 is connected to the side wall of the supporting vertical plate 10 through a reset spring sleeved on the reset column 23, and an electromagnetic plate 25 is arranged on the supporting vertical plate 10, and the magnetic repulsion disk 11 and the electromagnetic plate 25 repel each other magnetically.

[0023] It is worth noting that when the electromagnetic plate 25 is turned on, the magnetic repulsion force it generates on the magnetic repulsion disk 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 disk 11 will be driven to extend forward away from the supporting vertical plate 10, and its extension will contact the transmission shaft fork casting. The insertion picking piece set on the magnetic repulsion disk 11 will be locked with the corresponding structure on the transmission shaft fork.

[0024] A cutting picking piece is fixedly connected to the end of the magnetic repulsion disk 11. Further, the cutting picking piece includes a cutting plug 26, a telescopic opening is opened in the cutting plug 26, and a relatively set T-shaped block 27 is slidably set in the telescopic opening. Two adjacent T-shaped blocks 27 are connected by a resistance spring, and the side walls on both sides of the T-shaped block 27 are both arc-shaped.

[0025] It should be noted that when the T-shaped clamp 27 moves forward, the arc surface setting makes it easy for the T-shaped clamp 27 to be inserted into the transmission shaft fork casting, forming a clamping connection with the transmission shaft fork casting. Therefore, when the magnetic repulsion force fails, the elastic reset part generates an outward traction force on the transmission shaft fork casting, thereby pulling it outward at the moment the casting is cut and broken, avoiding the situation where the casting falls and causes quality damage and the cut casting affects subsequent cutting.

[0026] A lifting hydraulic cylinder 9 for lifting and lowering a control ring cover 8 is provided on the casting processing table 1. The lifting hydraulic cylinder 9 is a prior art and will not be described in detail here. A control ring cover 8 is connected to the top of multiple mounting sleeves 6 through a rotating connecting seat 7. An adjusting member for rotationally controlling the mounting sleeve 6 is provided on the control ring cover 8. Further, the adjusting member includes an adjusting motor 18 provided on the control ring cover 8. A linkage gear ring 19 is rotatably provided on the control ring cover 8. An adjusting master control gear 20 meshing with the linkage gear ring 19 is fixedly connected to the output end of the adjusting motor 18. An inner shaft body 21 is fixedly connected to the top of the mounting sleeve 6. The inner shaft body 21 extends upward through the rotating connecting seat 7 and is fixedly connected to an adjusting gear 22. The adjusting gear 22 meshes with the linkage gear ring 19.

[0027] The advantage of adopting the above structure is that multiple inner shafts 21 can be rotated synchronously through the control of the adjusting part, thereby controlling the rotation of the mounting sleeve 6, so that the transmission shaft fork casting originally inside the assembly separation ring body 5 is driven to rotate to face outward, thereby facilitating the grinding of its cut surface.

[0028] The multi-faceted cutting device includes a mounting base 12 connected to the robotic arm, the mounting base 12 is connected to an operating base 13 via a plurality of mounting columns, the outer wall of the operating base 13 is connected to a cutting disc 15 via a U-shaped frame 14, a cutting drive motor 16 is provided on the operating base 13, and the cutting drive motor 16 is connected to the plurality of cutting discs 15 via a driving device.

[0029] Furthermore, the driving device includes a driving gear 28 connected to the output end of the cutting drive motor 16, the cutting disc 15 is rotatably connected to the U-frame 14 through a cutting shaft 29, a worm gear 30 is fixedly connected to the end of the cutting shaft 29, the worm gear 30 is meshingly connected to a worm 31, the worm 31 is fixedly connected to a vertical shaft, the vertical shaft is rotatably connected to the operating seat 13, the vertical shaft extends upward through the operating seat 13, and is connected to a direct drive gear 32 meshingly connected to the driving gear 28. Through the setting of the driving device, multiple cutting discs 15 located on multiple surfaces can be synchronously driven, so that multiple castings located around the casting channel can be cut at the same time, significantly improving the casting segmentation efficiency.

[0030] When processing the casting taken out from the sand mold, the present invention installs the casting column formed by the pouring ports of multiple castings on the clamping member 4, and clamps and fixes the casting by the clamping member 4. By rotating the bearing processing plate 2, the casting is driven to rotate by the clamping member 4. The high-speed rotating casting causes the sand adhering thereto to be centrifugally dropped off, thereby cleaning the sand on the casting and preventing the presence of the sand from affecting the cutting effect of the subsequent cutting blade 15 on the casting. After completing the cleaning of the molding sand, while ensuring that the casting picking components installed in the installation sleeve 6 are facing the casting one by one, the electromagnetic plate 25 is controlled to be turned on. Under the action of the magnetic repulsion force, the magnetic repulsion disk 11 will be driven close to the casting, and the insertion picking part arranged thereon will be locked with the corresponding structure on the casting (the transmission shaft fork is used as an example for design in this scheme). At this time, the power supply of the electromagnetic plate 25 is released, and the magnetic repulsion disk 11 will generate an outward traction force on the casting under the action of the sleeve reset spring, thereby fixing the casting during the cutting process.

[0031] The multi-faceted cutting device is controlled by the mechanical arm to move downward, and the castings are cut one by one from top to bottom. When the casting is cut off, the cut casting will be driven by the cutting pick-up part under the action of traction force to move away from the cutting point to avoid secondary damage to the casting caused by the cutting tool. In the process of cutting one by one, the cutting pick-up part will pull and fix the castings one by one; After the cutting is completed, the motor 18 is adjusted to control the casting in the mounting sleeve 6 to flip 180 degrees so that it faces outward. At this time, the supporting 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 vertical cylinder 3 to rotate at high speed. The electromagnetic plate 25 is controlled to open and apply pressure to the casting so that the cut surface can be close to the grinding layer for rapid grinding, thereby achieving effective processing of the cut surface and ensuring the quality of the casting after cutting.

[0032] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
