[0039] The material fixing mechanism 51 comprises a general drive motor 9, a circular rotating disc 11, a connecting support column 12, a general electric telescopic rod 13, a material bearing plate 14, a side wall fixing groove 15, an elastic buffer rod 16, a buffer spring 17, a general electric telescopic rod 13 control button 18 and a concave moving clamping plate 19, the general drive motor 9 is arranged at the bottom of the inner partition plate 8, the circular rotating disc 11 is arranged inside the auxiliary rotating groove 10, both ends of the top of the circular rotating disc 11 are provided with the connecting support column 12, the top of the two connecting support columns 12 is provided with the material bearing plate 14, the outer wall of one side of the two connecting support columns 12 is provided with the general electric telescopic rod 13, the telescopic end of the two general electric telescopic rods 13 is provided with the concave moving clamping plate 19 matched with the material bearing plate 14, the cleaning mechanism 52 comprises a dust suction pipe 20, a blower 21, a conveying pipe 22, an air purification box 23, an air extractor 24, a suction pipe 25 and a suction cover 26, the blower 21 is arranged at the bottom of the inner wall of the external working box 1, one side of the blower 21 is provided with the air purification box 23, the other side of the air purification box 23 is provided with the air extractor 24, the other side of the blower 21 is provided with the dust suction pipe 20, the top end of the dust suction pipe 20 penetrates through the inner partition plate 8 and extends above the inner partition plate 8, the other side of the air extractor 24 is provided with the suction pipe 25, the top end of the suction pipe 25 penetrates through the inner partition plate 8 and extends above the inner partition plate 8.

[0040] In specific application, the general drive motor 9 is arranged at the bottom of the inner partition plate 8, so that the material bearing plate 14 can rotate in the horizontal direction, facilitating polishing operation on different parts of the gray iron casting. For example, when fine polishing is needed on one side of the casting, the side can be adjusted to a suitable polishing position by rotating the circular rotating disc 11 through the drive motor 9, improving the flexibility and efficiency of polishing. The two connecting support columns 12 are vertically arranged at the top of the two ends of the circular rotating disc 11, supporting the material bearing plate 14, the material bearing plate 14 provides a stable placement platform for the gray iron casting, the shape and size of which are determined according to the type and size of the casting to ensure that the casting can be placed stably thereon, and the strength and stability of the connecting support column 12 ensure that the material bearing plate 14 does not shake or tilt during polishing, thereby ensuring the accuracy and quality of polishing.

[0041] Two universal electric telescopic rods 13 are arranged on the outer wall on one side of the two connecting support columns 12, and the telescopic end is connected with the concave moving clamping plate 19 matched with the material bearing plate 14. By controlling the universal electric telescopic rod control button 18, the telescopic length of the universal electric telescopic rod 13 can be adjusted, so that the concave moving clamping plate 19 is close to or away from the gray iron casting on the material bearing plate 14. After the casting is placed on the material bearing plate 14, the electric telescopic rod 13 is elongated by operating the control button 18, and the concave moving clamping plate 19 tightly clamps the casting to prevent the casting from moving during polishing. The arrangement of the side wall fixed groove 15, the elastic buffer rod 16 and the buffer spring 17 further enhances the stability and adaptability of clamping. The side wall fixed groove 15 can better fit the shape of the casting, and the elastic buffer rod 16 and the buffer spring 17 can play a buffering role during clamping, avoiding damage to the casting due to excessive clamping force, and also adapting to castings of different shapes and sizes.

[0042] The air blower 21 is arranged at the bottom of the inner wall of the external working box 1, and generates strong suction force during work. The top end of the dust suction pipe 20 penetrates the inner partition plate 8 and extends above the inner partition plate 8, close to the material fixing mechanism 51 and the polishing area. During polishing, a large amount of dust and debris will be generated, which will be sucked into the air blower 21 through the dust suction pipe 20 and then transported to the air purification box 23. The air purification box 23 is usually provided with filtering devices such as filter screens and activated carbon inside, which can filter and purify the air sucked in, remove dust and harmful gases therefrom, and make the gas discharged into the air meet the environmental protection requirements. The air extractor 24 is arranged on the other side of the air purification box 23, and is connected with the air suction cover 26 through the air suction pipe 25. The air suction cover 26 is also arranged above the inner partition plate 8, close to the polishing area. When the air extractor 24 works, negative pressure will be generated at the air suction cover 26, further assisting the absorption of dust and waste gas generated during polishing.

[0043] Firstly, the gray iron casting to be polished is placed on the material bearing plate 14. Then, the universal electric telescopic rod control button 18 is operated to elongate the universal electric telescopic rod 13, which drives the concave moving clamping plate 19 to approach the casting, tightly clamping the casting. The side wall fixed groove 15, the elastic buffer rod 16 and the buffer spring 17 will adaptively adjust according to the shape and size of the casting, ensuring the stability and safety of clamping. When different parts of the casting need to be polished, the universal drive motor 9 is started, and the drive motor 9 drives the circular rotating disc 11 to rotate in the auxiliary rotating groove 10 through the transmission device, so as to drive the connecting support column 12, the material bearing plate 14 and the casting above to rotate, adjusting the position to be polished to a suitable polishing position.

[0044] In the polishing process, the operator uses the polishing tool to polish the casting. At the same time, the air blower 21 and the air extractor 24 start to work. The air blower 21 absorbs the dust and debris generated in the polishing area through the dust suction pipe 20 and transports them to the air purification box 23 for filtration and purification. The air extractor 24 further assists in absorbing dust and waste gas through the air suction pipe 25 and the air suction cover 26, and cooperates with the air blower 21 to form a high-efficiency air circulation and purification system, ensuring the air cleanliness of the polishing area.

[0045] In a possible implementation, the cooling treatment mechanism 50 includes a cooling liquid storage tank 27, a liquid delivery pipe 28, a general hydraulic cylinder 29, a connecting rod 30, an auxiliary rotating shaft 31, a cooling plate 32, and a liquid outlet nozzle 33. The cooling liquid storage tank 27 is arranged on the top of the external working box 1, the general hydraulic cylinder 29 is arranged on the inner wall of one side of the external working box 1, the output end of the general hydraulic cylinder 29 is provided with the connecting rod 30, the other end of the connecting rod 30 is provided with the cooling plate 32, and the surface of the cooling plate 32 is provided with a plurality of groups of liquid outlet nozzles 33 with the same size. The detection auxiliary mechanism 49 includes a general electric telescopic rod 34, a bottom fixed connecting block 35, an L-shaped auxiliary connecting rod 36, a side wall fixed groove 37, an elastic buffer rod 38, a buffer spring 39, an inner wall groove 40, an auxiliary sliding rod 41, a general hydraulic cylinder 42, an auxiliary moving sliding block 43, an auxiliary connecting fixed rod 44, an auxiliary connecting fixed rod 45, a general driving motor 46, a first polisher 47, a second polisher 48, and a lateral lifting auxiliary plate 54. The general electric telescopic rod 34 is arranged on the top of the inner partition plate 8, the lateral lifting auxiliary plates 54 are arranged on both sides of the top surface of the inner partition plate 8, the two lateral lifting auxiliary plates 54 are arranged on the telescopic ends of the general electric telescopic rod 34, the inner walls on one side of the two lateral lifting auxiliary plates 54 are provided with the inner wall grooves 40, the auxiliary sliding rods 41 are arranged in the inner wall grooves 40, the general hydraulic cylinder 42 is arranged on one side of the inner wall of the inner wall groove 40, the telescopic end of the general hydraulic cylinder 42 is provided with the auxiliary moving sliding block 43, the top end of one auxiliary moving sliding block 43 is provided with the auxiliary connecting fixed rod 44, and the top end of the other auxiliary moving sliding block 43 is provided with the auxiliary connecting fixed rod 45.

[0046] In a specific application, the cooling liquid storage tank 27 is installed on the top of the external working box body 1, the general type hydraulic cylinder one 29 is arranged on the inner wall of one side of the external working box body 1, which is the power source of the cooling plate 32, and can control the moving distance and speed of the cooling plate 32 by providing power through the hydraulic system. During the grinding process of the gray iron casting, according to the position and grinding progress of the casting, the hydraulic cylinder one 29 can drive the connecting rod 30 to drive the cooling plate 32 to approach or move away from the casting, so as to realize flexible cooling operation. The connecting rod 30 connects the output end of the general type hydraulic cylinder one 29 and the cooling plate 32, and plays a role in transmitting power, and the auxiliary rotating shaft 31 is arranged at the connection between the connecting rod 30 and the cooling plate 32, allowing the cooling plate 32 to rotate within a certain angle range, so that the cooling plate 32 can be adaptively adjusted according to the shape and angle of the casting surface, ensuring that the cooling liquid can be uniformly sprayed on the casting surface, and improving the cooling efficiency.

[0047] The cooling plate 32 is a key component for spraying cooling liquid, and a plurality of groups of liquid outlet nozzles 33 with the same size arranged on the surface of the cooling plate 32 can spray the cooling liquid in the form of uniform mist on the gray iron casting. The spraying range, spraying angle and spraying flow of the liquid outlet nozzles 33 are considered to ensure that the cooling liquid can cover the entire grinding area of the casting, effectively reduce the temperature of the casting during the grinding process, and prevent the casting from deforming and cracking due to overheating. The general type electric telescopic rod two 34 is installed on the top of the inner partition plate 8, which is a power device for lifting the lateral lifting auxiliary plate 54. Through electric control, the height of the lateral lifting auxiliary plate 54 can be adjusted to adapt to the detection and grinding requirements of gray iron castings of different sizes and shapes. During the detection process, the position of the lateral lifting auxiliary plate 54 can be adjusted according to the height of the casting, so that the detection equipment can accurately contact the surface of the casting.

[0048] The two lateral lifting auxiliary plates 54 are arranged on both sides of the top surface of the inner partition plate 8 and are connected to the telescopic end of the general type electric telescopic rod two 34, which not only plays a role in supporting and fixing other detection auxiliary components, but also can move up and down with the telescopic rod two 34, providing a suitable operation space for detection and grinding operation. The inner wall groove 40 opened in the inner wall of one side of the lateral lifting auxiliary plate 54 provides a mounting position for the auxiliary sliding rod 41 and the general type hydraulic cylinder two 42. The auxiliary sliding rod 41 is arranged inside the inner wall groove 40 to provide a guiding effect for the movement of the auxiliary moving slider 43. The general type hydraulic cylinder two 42 is installed on one side of the inner wall of the inner wall groove 40, and the telescopic end is connected to the auxiliary moving slider 43. Under the drive of the hydraulic cylinder two 42, the auxiliary moving slider 43 can move smoothly along the auxiliary sliding rod 41. This allows the auxiliary connecting fixed rod one 44 and the auxiliary connecting fixed rod two 45 to accurately move to the specified position, providing accurate positioning for subsequent grinding operation.

[0049] The top end of the auxiliary moving slider 43 is provided with an auxiliary connecting fixed rod one 44, and the top end of the other auxiliary moving slider 43 is provided with an auxiliary connecting fixed rod two 45. The two fixed rods serve as components for connecting other polishing devices, and can accurately fix the universal driving motor two 46, the first polisher 47 and the second polisher 48 at the required positions. Through the movement of the auxiliary moving slider 43, the distance and angle between the polishing device and the gray iron casting can be adjusted, so as to realize accurate polishing operation. The universal driving motor two 46 provides power for the first polisher 47 and the second polisher 48. The first polisher 47 and the second polisher 48 can be selected and replaced according to different polishing requirements. For example, the first polisher 47 can be used for rough polishing to remove large defects and excess material on the surface of the casting; and the second polisher 48 can be used for fine polishing to make the surface of the casting reach a higher smoothness. Through the fixing and adjustment of the auxiliary connecting fixed rod one 44 and the auxiliary connecting fixed rod two 45 and the driving of the universal driving motor two 46, accurate polishing of the gray iron casting is realized.

[0050] In the positioning and polishing process of the gray iron casting, the cooling treatment mechanism 50 and the detection auxiliary mechanism 49 work cooperatively. First, the universal electric telescopic rod two 34 in the detection auxiliary mechanism 49 adjusts the height of the lateral lifting auxiliary plate 54, so that the polishing device can adapt to the height of the casting. Then, the universal hydraulic cylinder two 42 drives the auxiliary moving slider 43 to move, and drives the auxiliary connecting fixed rod one 44 and the auxiliary connecting fixed rod two 45 to move the first polisher 47 and the second polisher 48 to the appropriate polishing position. At the same time, the universal driving motor two 46 is started to drive the polisher to polish the casting.

[0051] In the polishing process, the cooling treatment mechanism 50 starts to work. The universal hydraulic cylinder one 29 drives the connecting rod 30 to drive the cooling plate 32 to approach the casting. The cooling liquid in the cooling liquid storage tank 27 is transported to the cooling plate 32 through the liquid delivery pipe 28, and is uniformly sprayed on the surface of the casting by the liquid outlet nozzle 33, so as to reduce the temperature of the casting and prevent the polishing quality and the performance of the casting from being affected by overheating.

[0052] In a possible implementation, the output end of the general-purpose driving motor 9 is arranged at the bottom of the circular rotating disc 11, the inner walls on both sides of the material bearing plate 14 are provided with sidewall fixed grooves I 15, the outer wall of one side of the concave movable clamping plate 19 is provided with a movable connecting block 53, the movable connecting block 53 is arranged in the sidewall fixed groove I 15, the sidewall fixed groove I 15 is provided with an elastic buffer rod I 16, the outer wall of the elastic buffer rod I 16 is provided with a buffer spring I 17, one side of the inner wall of the sidewall fixed groove I 15 is provided with a general-purpose electric telescopic rod I control button 18, and the general-purpose electric telescopic rod I control button 18 is electrically connected with the general-purpose electric telescopic rod I 13. The air blower 21 and the air purification tank 23 are provided with a conveying pipe 22, the air purification tank 23 and the air blower 24 are provided with a conveying pipe 22, the top end of the air suction pipe 25 is provided with a matching air suction cover 26, one side of the cooling liquid storage tank 27 is provided with a liquid conveying pipe 28, the bottom end of the liquid conveying pipe 28 penetrates into the inside of the external working tank body 1 and communicates with the inside of the cooling plate 32, and the auxiliary rotating shaft 31 is arranged in the connecting rod 30.

[0053] In the specific application of the embodiment, the output end of the general-purpose driving motor 9 is directly connected to the bottom of the circular rotating disc 11, ensuring that the rotating disc can rotate stably and accurately, and the driving motor provides stable power output, so that the rotating disc can adjust the position of the gray iron casting as needed, facilitating multi-angle operation during polishing. The sidewall fixed groove I 15 provided on the inner walls on both sides of the material bearing plate 14 provides a stable moving track for the concave movable clamping plate 19, not only enhancing the stability of the clamping structure, but also allowing the clamping plate to be flexibly adjusted according to the size of the casting.

[0054] The concave movable clamping plate 19 slides in the sidewall fixed groove I 15 through the movable connecting block 53, realizing clamping of the gray iron casting, and the elastic buffer rod I 16 and the buffer spring I 17 arranged in the sidewall fixed groove I 15 play a buffering role during clamping, preventing damage to the surface of the casting due to excessive clamping force, while ensuring the stability of clamping. The general-purpose electric telescopic rod I 13 is controlled through the general-purpose electric telescopic rod I control button 18 arranged on the inner wall of the sidewall fixed groove I 15, so that the operator can adjust the length of the electric telescopic rod by pressing the control button according to the actual size of the casting, and then drive the concave movable clamping plate 19 to perform clamping operation, improving the flexibility and efficiency of positioning and polishing.

[0055] The air blower 21 is connected with the air purification box 23 through the conveying pipe 22, forming an effective dust collection system. During the grinding process, the air blower generates negative pressure, and the dust generated by grinding is sucked into the conveying pipe 22 through the air suction pipe 25 and the air suction cover 26, and then conveyed to the air purification box 23 for purification treatment. The air purification box 23 is internally provided with a high-efficiency filtering device, which can remove dust particles in the sucked air. The purified air is then extracted by the air extractor 24 through another conveying pipe 22 and discharged into the working environment, ensuring the air quality of the working area.

[0056] The cooling liquid storage tank 27 delivers cooling liquid to the cooling plate 32 inside the external working box 1 through the liquid conveying pipe 28, so that the cooling liquid can continuously cool the grinding area during the grinding process, preventing the deformation of the casting or the damage of the grinding tool caused by high temperature. The cooling plate 32 is arranged inside the connecting rod 30, and the auxiliary rotating shaft 31 is also arranged in the connecting rod 30, so that the cooling plate can adjust the position with the rotation of the connecting rod, ensuring that the cooling liquid can uniformly cover the grinding area.

[0057] In one possible implementation, the top surface of the internal partition plate 8 is provided with a bottom fixed connecting block 35 at both ends, an L-shaped auxiliary connecting rod 36 is arranged on the top of the bottom fixed connecting block 35, the outer walls of the lateral lifting auxiliary plate 54 are provided with a side wall fixed groove two 37 on both sides, one end of the L-shaped auxiliary connecting rod 36 is arranged in the side wall fixed groove two 37, the inside of the side wall fixed groove two 37 is provided with an elastic buffer rod two 38, the outer wall of the elastic buffer rod two 38 is provided with a matching buffer spring two 39, the top end of the auxiliary moving block 43 is provided with an auxiliary connecting fixed rod one 44 and an auxiliary connecting fixed rod two 45, one side of the auxiliary connecting fixed rod one 44 and the auxiliary connecting fixed rod two 45 is provided with a universal driving motor two 46, the output end of one universal driving motor two 46 is provided with a first grinder 47, and the output end of the other universal driving motor two 46 is provided with a second grinder 48. The surface of one side of the external working box 1 is provided with an access door 4, the surface of the access door 4 is provided with a viewing window 5, the lower side of the viewing window 5 is provided with an electrical control panel 6, the other side of the electrical control panel 6 is provided with an auxiliary handle 7, the outer wall of the auxiliary handle 7 is provided with a protective pattern, the universal electric telescopic rod one 13, the universal electric telescopic rod two 34, the universal hydraulic cylinder one 29, the universal electric telescopic rod two 34, the universal driving motor one 9, the universal driving motor two 46, the air blower 21, the air purification box 23 and the air extractor 24 are respectively electrically connected between the electrical control panel 6 through the conducting wire.

[0058] In the specific application, the bottom fixed connecting block 35 arranged at the top of the inner partition plate 8 is made of high-strength material, which can withstand large pressure and torque, ensures the firm and reliable connection with the inner partition plate 8, provides a stable installation basis for the L-shaped auxiliary connecting rod 36, so that the L-shaped auxiliary connecting rod 36 can be accurately positioned and fixed, thereby ensuring the position accuracy of the subsequent connected components.

[0059] The L-shaped auxiliary connecting rod 36 is in L-shaped structure, which can adapt to long-term use and frequent movement, and the connecting parts of the bottom fixed connecting block 35 and the lateral lifting auxiliary plate 54 adopt precise fitting modes such as clearance fit or interference fit to ensure the tightness of the connection and the stability of the movement. One end is fixed on the bottom fixed connecting block 35, and the other end is inserted into the side wall fixed groove two 37 of the lateral lifting auxiliary plate 54, which plays a role in transmitting force and movement, and limits the movement of the lateral lifting auxiliary plate 54 in the horizontal direction, ensuring the accuracy of the movement of the lateral lifting auxiliary plate 54.

[0060] The side wall fixed groove two 37 arranged on the outer wall of the lateral lifting auxiliary plate 54 is in a special groove shape, the size and shape of the groove are matched with the end of the L-shaped auxiliary connecting rod 36, which can accurately accommodate the end of the L-shaped auxiliary connecting rod 36 and provide stable support. The lateral lifting auxiliary plate 54 is internally provided with a reinforcing rib structure to increase its overall strength and rigidity, preventing deformation during lifting. Through cooperation with the L-shaped auxiliary connecting rod 36, the lateral lifting auxiliary plate 54 realizes stable lifting movement in the vertical direction. The elastic buffer rod two 38 and the buffer spring two 39 inside the side wall fixed groove two 37 play a role in buffering and shock absorption, reducing the impact force during movement and protecting the equipment and castings.

[0061] The elastic buffer rod two 38 is made of high-elasticity material and has good elastic deformation capacity. The buffer spring two 39 arranged on the outer wall of the elastic buffer rod two 38 is made of high-quality spring steel and has stable elastic properties and a long service life after special processing. The pitch and diameter of the buffer spring two 39 are accurately calculated to provide appropriate elastic force when the lateral lifting auxiliary plate 54 moves, thereby achieving the effect of buffering and shock absorption.

[0062] When the lateral lifting auxiliary plate 54 is impacted by external force during lifting, the elastic buffer rod two 38 and the buffer spring two 39 can be elastically deformed to absorb and disperse the impact energy, reduce the impact force on other parts of the equipment, and improve the operation stability and reliability of the equipment. The auxiliary connecting fixed rod one 44 and the auxiliary connecting fixed rod two 45 provided at the top end of the auxiliary moving slider 43 are connected in a high-strength manner such as threaded connection or welding, ensuring firm and reliable connection with the general type driving motor two 46. The size and shape of the auxiliary connecting fixed rod are determined according to the installation requirements of the general type driving motor two 46, which can accurately position and fix the motor.

[0063] First, the gray iron casting is placed on the positioning device of the positioning polishing table, and the casting is precisely positioned through the positioning device. Then, according to the polishing requirements of the casting, the auxiliary moving slider 43 is started to move the auxiliary connecting fixed rod one 44 and the auxiliary connecting fixed rod two 45 and the general type driving motor two 46 to the appropriate position. Next, the general type driving motor two 46 is started to drive the first polisher 47 and the second polisher 48 to rotate at high speed. At the same time, the distance between the polisher and the surface of the casting is adjusted through the lifting movement of the lateral lifting auxiliary plate 54, so that the polisher can accurately contact the surface of the casting for polishing. During polishing, the elastic buffer rod two 38 and the buffer spring two 39 play a buffering and damping role to ensure smooth polishing process. By continuously adjusting the position and speed of the polisher, full-range and high-precision polishing of the gray iron casting is realized.
