[0026] Please refer to Figure 1 - Figure 6 , and on the basis of Embodiments 1, 2, and 3, it is further obtained that the specific structure of the grinding assembly 4 includes a fixed seat 41 and a connecting column 46. The fixed seat 41 and the connecting column 46 are both installed on the base 11; A limiting block 42 is fixedly connected to the top of the fixed seat 41.

Embodiment

[0028] Please refer to Figure 1 - Figure 6, and on the basis of Embodiments 1, 2, 3, and 4, it is further obtained that: The specific structure of the adsorption component 5 includes a curved plate 51, the curved plate 51 is fixedly installed on the base 11, a connecting plate 52 is fixedly installed on the top of the curved plate 51, and two support bearing seats 53 are installed on the front of the connecting plate 52. The support bearing seat 53 located above is connected to a driving seat 54 through a rotating column A 55, and the support bearing seat 53 located below is connected to a connecting rod seat 57 through a rotating column B 56. The top end of the connecting rod seat 57 is connected to the rotating column A 55; A connecting hoop 58 is fixedly installed on the back of the curved plate 51. An air pump 59 is built in the connecting hoop 58. The air pump 59 is connected to a pressing cylinder 511 through an air pipe 510. An adsorption disc 512 is provided at the bottom of the pressing cylinder 511. The adsorption disc 512 realizes stable adsorption of the workpiece through air pressure control. An electronic pressure valve meter 513 is arranged on the air pipe 510. The electronic pressure valve meter 513 precisely adjusts the air pressure to ensure moderate adsorption force and prevent damage to the workpiece; The pressing cylinder 511 movably penetrates through the driving seat 54, and tooth grooves are equidistantly arranged on one side of the outer wall of the pressing cylinder 511. A compression spring 514 is sleeved outside the pressing cylinder 511. One end of the compression spring 514 is fixed to the top of the driving seat 54, and the other end is fixedly connected to the head of the pressing cylinder 511. Buffer rubber columns 515 are fixedly connected to the top of the driving seat 54 and the head of the pressing cylinder 511; A gear chamber is arranged inside the driving seat 54, and a driving gear 517 is installed in the gear chamber. The driving gear 517 meshes with the tooth grooves of the pressing cylinder 511. The axis of the driving gear 518 is connected to the output end of the motor three 516, driving the pressing cylinder 511 to move up and down to realize precise positioning of the adsorption disc 512. The motor three 516 is installed on the outer surface of the driving seat 54.

[0029] When the motor three 516 is started, the driving gear 517 rotates, driving the pressing cylinder 511 to move downward, and then driving the adsorption disc 512 to closely adhere to the surface of the workpiece. The compression spring 514 compresses to provide a reverse supporting force. At the same time, the air pump 59 is started, and the air flow at the contact between the adsorption disc 512 and the oval head bolt is quickly evacuated, forming a negative pressure environment. The oval head bolt is firmly adsorbed. The electronic pressure valve meter 513 monitors and finely adjusts the air pressure in real time to form a stable adsorption force. At the same time, the buffer rubber columns 515 effectively reduce vibration, protect the workpiece and the equipment, and improve the overall operation stability and safety.

[0030] During use, first, the air pump 59 is operated through the control system to quickly evacuate air to form a negative pressure. The operator holds the oval head bolt to be polished, and its head surface is firmly adsorbed on the adsorption disc 512. The electronic pressure valve meter 513 adjusts the air pressure in real time to ensure a constant adsorption force and prevent the bolt from shifting. Then, the motor three 516 is started, and the driving gear 517 drives the pressing cylinder 511 to accurately descend, so that the pressing cylinder 511 drives the bolt tightly adsorbed by the adsorption disc 512 to descend to the clamping area; Then, the control system is used to start Motor Two 314, driving Gear 312 to rotate. Gear 312 drives Tooth Block 310 to move along Slide Rail 311, thereby pushing Moving Rod 35 to extend forward in Fixed Cylinder 34. Clamping Head 37 drives Movable Clamping Seat 38 to closely fit the oval head bolt. In close cooperation with Fixed Clamping Seat 315, a stable clamping force is formed to ensure that the bolt does not displace during the grinding process, achieving a firm clamping; After clamping, Air Pump 59 stops operating, and Suction Disc 512 gradually releases negative pressure. The oval head bolt remains stationary under the action of the clamping force. Motor Three 516 rotates in reverse, driving Gear 517 to drive Pressing Cylinder 511 to rise, ensuring the separation of Suction Disc 512 from the bolt. The entire device enters the standby state, waiting for the next operation instruction; Subsequently, the operator confirms the clamping state through the control system. Then, the process of Electric Grinder 410 is adjusted by Telescopic Cylinder 49. Electric Grinder 410 precisely contacts the surface of the bolt, and Atomizing Nozzle 411 synchronizes the process. At the same time, Electric Grinder 410 and Motor One 21 are turned on. Motor One 21 drives Small Gear 22 to rotate, driving Large Gear 23 and Rotating Table 25 to rotate synchronously, thereby driving the bolt to rotate uniformly (it should be noted that all clamping devices on Rotating Table 25 will not be hindered by Grinding Assembly 4 and Adsorption Assembly 5 during the rotation process. The clamping force and rotational force are perfectly matched to ensure uniform grinding without dead corners). Electric Grinder 410 efficiently grinds, and Atomizing Nozzle 411 continuously cools down to ensure that the surface of the bolt is evenly ground and does not overheat, thereby improving the grinding quality and efficiency; Finally, after grinding is completed, the operator stops all motors through the control system. Electric Grinder 410 resets, Atomizing Nozzle 411 stops spraying water, and Clamping Head 37 and Movable Clamping Seat 38 are loosened synchronously. At this time, Electric Telescopic Rod 44 is started through the control system. Electric Telescopic Rod 44 drives Three - Legged Special - Shaped Plate 45 to adjust the angle, enabling Three - Legged Special - Shaped Plate 45 to rotate flexibly around the support point connected to the top of Connecting Column 46. Thereby driving the ejector rod 48 on Linking Block 47 to perform a linear motion under the limiting action of Limiting Block 42. Ejector Rod 48 precisely pushes the bolt out of the clamping area to take out the bolt.
