[0037] At least one lifting cylinder 2 is arranged below the support plate 1, and the piston rod of the lifting cylinder 2 is connected to the lower surface of the support plate 1, so that the support plate 1 can move in the vertical direction.

[0039] The support plate is driven downward by the lifting cylinder, and the opening and closing cylinder, the rotating plate, the clamping assembly, and the cover plate clamped by the clamping assembly on the rotating plate are all moved downward until the elastic support plate and the pressing block on the lower surface of the cover plate contact the upper surface of the main body of the workpiece to be processed, and the positioning column on the machine table passes through the positioning hole on the cover plate to ensure the position accuracy of the cover plate;

[0048] The plurality of pressing blocks 600 are arranged around the elastic supporting plate 500 .

[0049] The working principle of the utility model is as follows:

[0050] When in the processing state: the workpiece to be processed is installed between the carrier plate and the cover plate, so that the lower surface of the main body of the workpiece contacts the upper surface of the carrier plate, the upper surface contacts the lower surface of the elastic support plate, and the lower surface of the pressing block installed around the lower surface of the cover plate contacts the upper surface around the main body of the workpiece;

[0051] Since the cover plate is generally made of metal and has a large deadweight, the surface contact between the main body of the workpiece and the elastic support plates, pressure blocks and carrier plates above and below it can be initially maintained under the pressure of the cover plate itself; then, by starting the vacuum pump or vacuum generator, a gas flow path is generated from the gas groove on the lower surface of the elastic support plate, the second through hole on the main body of the workpiece, and the adsorption holes on the upper surface of the carrier plate to the vacuum pump or vacuum generator, thereby generating an adsorption force on the elastic support plate above the workpiece, thereby enhancing the downward force of the cover plate fixedly connected to the elastic support plate and the pressure blocks installed on the cover plate, thereby achieving stable pressure holding of the main body of the workpiece, especially the edges around it;

[0052] Next, the CNC tool is used to perform full-circle milling on the edges of the workpiece. During the processing, the pressure applied by the pressure block is close to the processing area, so the occurrence of tool chattering can be effectively avoided, ensuring the quality and yield of the processed surface.

[0053] When the processing is completed: first, the support plate is driven to move up to a high position by the lifting cylinder, and then the push block is driven to move up to a high position by the opening and closing cylinder so that the rotating plate that rotates with the upward movement of the push block rotates to a horizontal position, and the clamping assembly installed on the rotating plate rotates to the top of the part to be clamped on the cover plate; at this time, the connecting rod rotates to a vertical state, and the pin moves to the upper end of the guide groove;

[0054] Next, the support plate is driven downward by the lifting cylinder, and the opening and closing cylinder, the rotating plate, and the clamping assembly are all moved downward accordingly. Then, the clamping cooperation between the clamping assembly and the part to be clamped is used to achieve stable clamping of the entire cover plate. The clamping assembly and the part to be clamped here do not belong to the invention of this patent. They can be obtained through external purchase, or the scheme in the applicant's prior application (application number 2024102325213) can be adopted, which will not be repeated here.

[0055] Turn off the vacuum pump or vacuum generator, and drive the support plate to move up to the high position again through the lifting cylinder, and the opening and closing cylinder, the rotating plate, the clamping assembly and the cover plate clamped by the clamping assembly are all moved up accordingly, so that the positioning holes on the cover plate are separated from the positioning columns on the machine table, and at the same time, the elastic support plate and the pressing block installed on the cover plate are also vertically away from the processed workpiece surface without damaging the workpiece;

[0056] Then, the processed workpiece on the carrier is removed manually or by automated equipment, and a new workpiece to be processed is placed on the carrier;

[0057] The piston rod of the lifting cylinder is placed in an extended state, and at the same time, the opening and closing cylinder drives the push block to move up to a high position so that the rotating plate that rotates with the upward movement of the push block and the cover plate clamped by the clamping assembly on the rotating plate are both rotated from a 110° position to a 90° position and then to a horizontal position;

[0058] The support plate is driven downward by the lifting cylinder, and the opening and closing cylinder, the rotating plate, the clamping assembly, and the cover plate clamped by the clamping assembly on the rotating plate are all moved downward until the elastic support plate and the pressing block on the lower surface of the cover plate contact the upper surface of the main body of the workpiece to be processed, and the positioning column on the machine table passes through the positioning hole on the cover plate to ensure the position accuracy of the cover plate;

[0059] Afterwards, the clamping assembly releases the part to be clamped, and the supporting plate is driven to move up to a high position again by the lifting cylinder. The opening and closing cylinder, the rotating plate, and the clamping assembly are all moved up and separated from the cover plate. Then the push block is driven down to a low position by the opening and closing cylinder. During this process, the rotating plate is rotated from the horizontal position to a 90° position again.

[0060] When the above-mentioned CNC processing device that is easy to load is used, it can realize automatic picking and placing of the cover plate, while ensuring the position accuracy of the cover plate during long-term and repeated picking and placing of the cover plate, thereby ensuring the stability of the workpiece pressure, and avoiding damage to the workpiece caused by the displacement during the opening and closing of the cover plate. It can also improve the stability of the workpiece pressure, especially near the surrounding processing areas, avoid the situation that affects the quality of the processed surface such as tool vibration during milling, and improve the processing quality.

[0061] The above embodiments are only for illustrating the technical concept and features of the utility model, and their purpose is to enable people familiar with the technology to understand the content of the utility model and implement it accordingly, and they cannot be used to limit the protection scope of the utility model. Any equivalent changes or modifications made according to the spirit of the utility model should be included in the protection scope of the utility model.
