[0018] Reference Figures 1-4 A metal casting processing and grinding device includes a housing 1 with a bench vise 3 installed on the bottom inner wall and a fixing frame 7. The metal frame to be ground is clamped and positioned by the bench vise 3, and a silicone pad can be attached to the clamping wall of the bench vise 3. The top of the housing 1 is provided with a grinding assembly 6, which includes a cylinder. One end of the cylinder piston rod passes through the housing 1 and is fixed with a first linear motor. A second linear motor is fixed to the slider part of the first linear motor by bolts. The first linear motor and the second linear motor move laterally and longitudinally, respectively. The first and second linear motors can be selected as flat linear motors, and the STANDARDTRACKA series models can be selected, which have large thrust and flexible stroke. The fixed frame 7 is fixed to the slider part of the second linear motor. The motor is fixed inside the fixed frame 7 by bolts. One end of the motor output shaft passes through the fixed frame 7 and is fixed to the grinding head by bolts. The rotation of the motor drives the grinding head to rotate. A polyurethane grinding head can be used, which has elastic polishing characteristics and can avoid scratching the aluminum alloy surface. The cylinder extends, causing the first linear motor to drive the second linear motor to move downward, which in turn causes the fixed frame 7 to drive the grinding head at the bottom of the motor to move downward, so that the grinding head contacts the metal frame for grinding. The position of the grinding head can be adjusted by adjusting the position of the sliders corresponding to the first and second linear motors. The bottom outer wall of the fixed frame 7 is fixed with a fixed cylinder 5 by bolts. A rubber slip ring 4 is slidably connected to the outer side of the bottom end of the fixed cylinder 5. The rubber slip ring 4 is made of polyurethane wear-resistant rubber. When stationary, the bottom of the rubber slip ring 4, which hangs down naturally under the action of gravity, is on the same horizontal plane as the bottom of the grinding head. The grinding head is located inside the space enclosed by the fixed cylinder 5 and the rubber slip ring 4. When the fixed frame 7 moves downward, the fixed cylinder 5 drives the rubber slip ring 4 to move downward. Since the grinding head and the bottom of the rubber slip ring 4 are kept on the same horizontal plane, the bottom of the rubber slip ring 4 contacts the metal frame, thereby causing the waste generated during grinding to be surrounded in the space between the fixed cylinder 5 and the rubber slip ring 4. Two guide blocks 10 are bonded to the inner wall of the rubber slip ring 4. The guide blocks 10 are made of polytetrafluoroethylene and are coated with grease to reduce frictional resistance. Two sliding grooves 8 are opened on the outer side of the fixed cylinder 5, and the guide blocks 10 are slidably connected with the corresponding sliding grooves 8. The guide blocks 10 and the sliding grooves 8 are fitted with a clearance of 0.5-1mm. Through the cooperation of the sliding grooves 8 and the guide blocks 10, it is ensured that when the grinding head is pressed down, the rubber slip ring 4 can automatically avoid movement interference when the grinding head grinds the thicker part of the metal frame. An installation port is provided on one side of the housing 1, and a flexible hose 9 is provided inside the installation port. One end of the flexible hose 9 is connected and fixed to the fixing cylinder 5. The flexible hose 9 is a plastic corrugated pipe. A support plate is fixed to one side of the outer wall of the housing 1 by bolts. A vortex air pump 11 is fixed to the upper surface of the support plate by bolts. The vortex air pump 11 can be a high-pressure vortex air pump and is electrically connected to a frequency converter and a PLC controller. The suction range of the vortex air pump 11 is 20-80 kPa. For example, the model is 2RB820-7HT37. It can generate a negative pressure of 22 kPa and is suitable for industrial dust removal and waste collection. The outer wall of the housing 1 is fixed to the outer shell 2 by bolts, and one end of the hose 9 passes through the housing 1 and enters the outer shell 2. A connection port is opened on one side of the outer shell 2, and the air intake port of the vortex air pump 11 is connected and fixed to the connection port to ensure that waste can be sucked into the collection box 13. The outer casing 2 is equipped with a collection box 13. When the vortex air pump 11 is started, it generates suction, which causes the waste debris inside the fixed cylinder 5 and the rubber slip ring 4 to enter the outer casing 2 through the hose 9 and then enter the collection box 13 for collection. The vortex air pump 11, the cylinder, the first linear motor, the second linear motor, and the motor are all connected to the PLC controller, which is fixed to one side of the housing 1 by bolts. The collection box 13 is fixed to the outer shell 2 by two detachable pin assemblies. The pin assembly includes a fixing block 16, which is fixed to one side of the outer wall of the collection box 13 by bolts. The fixing block 16 has a threaded groove 15. Both sides of the outer wall of the outer shell 2 are fixed with protrusions 14 by bolts. Bolts 18 are inserted into the protrusions 14 and are threadedly connected to the threaded grooves 15. When it is necessary to disassemble the collection box 13, the bolts 18 are rotated to move upward until they are separated from the threaded grooves 15. At this time, the collection box 13 is unrestricted. The staff can pull the collection box 13 downward to separate it from the outer shell 2, so that the staff can collect and process the waste inside the collection box 13.

[0019] In this utility model, it should be noted that the top of the bolt 18 passes through the protrusion 14 and is threadedly connected to a locking nut 17, and the bottom of the locking nut 17 is in contact with the upper surface of the protrusion 14. The locking nut 17 can further restrict the position of the bolt 18 to prevent the bolt 18 from rotating and affecting the use of the device. A filter plate 12 is detachably connected to the connection port by bolts. The filter plate is made of stainless steel wire mesh with a pore size of 0.5mm, which can intercept more than 90% of waste particles larger than 0.5mm. The filter plate 12 can filter the connection port to prevent the attracted impurities from entering the vortex air pump 11 through the connection port.

[0020] Working principle: When grinding a metal frame, firstly, the metal frame to be ground is clamped and positioned using a bench vise 3. Then, the cylinder and motor are started. The motor rotation drives the grinding head to rotate. The cylinder extension causes the first linear motor to drive the second linear motor to move downwards, thereby causing the fixing frame 7 to move the grinding head at the bottom of the motor downwards, so that the grinding head contacts the metal frame for grinding. At the same time, the downward movement of the fixing frame 7 causes the fixing cylinder 5 to drive the rubber slip ring 4 downwards. Since the bottom of the grinding head and the rubber slip ring 4 are kept on the same horizontal plane, the bottom of the rubber slip ring 4 contacts the metal frame. The frame contacts the grinding head, causing the waste generated during grinding to be contained within the space between the fixed cylinder 5 and the rubber slip ring 4. Then, the vortex air pump 11 is activated to generate suction, allowing the waste inside the fixed cylinder 5 and the rubber slip ring 4 to enter the outer casing 2 through the hose 9 and be collected in the collection box 13. Through the cooperation of the sliding groove 8 and the guide block 10, the rubber slip ring 4 can automatically avoid movement interference when the grinding head grinds the thicker part of the metal frame. The position of the grinding head can be adjusted by adjusting the position of the sliders corresponding to the first linear motor and the second linear motor.
