The upper end of the piston rod 4 of the opening and closing cylinder 3 is mounted with a push block 5. A support seat 6 is mounted on the upper surface of the support plate 1 and on the right side of the piston rod 4 of the opening and closing cylinder 3.

[0022] Since the cover plate is generally made of a metal part and has a relatively large self-weight, therefore, under the action of its own pressure, it can initially maintain surface contact with the workpiece;

[0023] A guiding support 10 is mounted on the upper surface of the support plate 1. The front side plate 11 and the rear side plate 12 of the guiding support 10 are respectively located on both sides of the rotating plate 7.

The lower end of the second guiding portion 132 connected to the upper end of the first guiding portion 131 extends to the right. A strip-shaped hole 14 for the pin shaft 8 to pass through is formed on the pushing block 5. When the piston rod 4 of the opening and closing air cylinder 3 is in the extended state, the pin shaft 8 is located at the left end of the strip-shaped hole 14 extending horizontally. When the piston rod 4 of the opening and closing air cylinder 3 is in the contracted state, the pin shaft 8 moving to the lower end of the second guiding portion 132 of the guiding groove 13 is located at the right end of the strip-shaped hole 14.

[0024] The workpiece is subjected to full circumferential milling by a CNC tool.

[0025] After the machining is completed: The pushing block is driven by the opening and closing air cylinder to move up to a high position, so that the rotating plate rotating with the upward movement of the pushing block rotates to the horizontal, and the clamping assembly mounted on the rotating plate rotates to above the workpiece to be clamped on the cover plate; At this time, the connecting rod rotates to the vertical state, and the pin shaft moves to the upper end of the first guiding portion of the guiding groove and the end of the strip-shaped hole on the pushing block far away.

[0026] A machine table 200 is arranged below the cover plate 400, and a carrier plate 300 is arranged on the upper surface of the machine table 200.

[0027] When in the machining state: The workpiece to be machined is installed between the carrier plate and the cover plate, so that the lower surface of the workpiece contacts the upper surface of the carrier plate and the upper surface contacts the lower surface of the cover plate.

[0028] A plurality of adsorption holes 301 are formed on the upper surface of the carrier plate 300, and the adsorption holes 301 are communicated with a vacuum pump through a pipeline.

[0029] A cavity 201 is formed between the machine table 200 and the carrier plate 300. The cavity 201 is communicated with a vacuum pump installed on the machine table 200 through a pipeline, and the adsorption holes 301 are communicated with the cavity 201 through a pipeline opened on the carrier plate 300.

[0030] Embodiment 2: A pressing cover plate for a notebook upper cover, comprising: a cover plate 400 with a workpiece 401 to be clamped mounted on its upper surface, a clamping assembly 100 that clamps and cooperates with the workpiece 401 to be clamped, and a support plate 1. A opening and closing cylinder 3 is fixedly mounted on the lower surface of the support plate 1. The upper end of the piston rod 4 of the opening and closing cylinder 3 is mounted with a push block 5. A support seat 6 is mounted on the upper surface of the support plate 1 and to the right of the piston rod 4 of the opening and closing cylinder 3. One end of a rotating plate 7 is rotatably connected to the push block 5 through a pin shaft 8. The other end of the rotating plate 7 extends to the right and is mounted with the clamping assembly 100. The upper end of the support seat 6 is rotatably mounted with a connecting rod 9. The other end of the connecting rod 9 connected to the support seat 6 is connected to the rotating plate 7. When the piston rod 4 of the opening and closing cylinder 3 is in the extended state, the rotating plate 7 is in a horizontal state and the connecting rod 9 is in a vertical state. The clamping assembly 100 is located above the workpiece 401 on the cover plate 400.

[0031] A guiding support 10 is mounted on the upper surface of the support plate 1. The front side plate 11 and the rear side plate 12 of the guiding support 10 are respectively located on both sides of the rotating plate 7. A guiding groove 13 for the pin shaft 8 to be inserted into is provided on both the front side plate 11 and the rear side plate 12. The guiding groove 13 includes a first guiding portion 131 extending in the vertical direction and a second guiding portion 132 extending obliquely. The lower end of the second guiding portion 132 connected to the upper end of the first guiding portion 131 extends to the right. A strip-shaped hole 14 for the pin shaft 8 to pass through is provided on the push block 5. When the piston rod 4 of the opening and closing cylinder 3 is in the extended state, the pin shaft 8 is located at the left end of the strip-shaped hole 14 extending horizontally. When the piston rod 4 of the opening and closing cylinder 3 is in the contracted state, the pin shaft 8 moving to the lower end of the second guiding portion 132 of the guiding groove 13 is located at the right end of the strip-shaped hole 14.

[0032] By driving the push block to move down to a low position through the opening and closing cylinder, during this process, the pin shaft first moves vertically downward along the first guiding portion of the guiding groove. The rotating plate rotatably connected to the push block through the pin shaft rotates from the horizontal position to the vertical (90°) position accordingly, and at the same time drives the clamped cover plate to also rotate from the horizontal position to the vertical position. Under the action of the downward pulling force of the push block, the pin shaft continues to move down and enters into the second guiding portion of the guiding groove, and moves along the obliquely arranged second guiding portion to the lower end of the second guiding portion. During this process, the pin shaft also moves from one end to the other end in the strip-shaped hole on the push block, and the rotating plate also continues to rotate outward along with the movement of the pin shaft, and the cover plate also continues to rotate outward to the 110° position, so as to be far away from the workpiece to be processed, facilitating the CNC tool to perform one-time processing on the periphery of the workpiece to be processed, and improving the processing efficiency and convenience.

[0033] A machine table 200 is arranged below the cover plate 400. A carrier plate 300 is arranged on the upper surface of the machine table 200.

[0034] A plurality of positioning pins 2 for fixing workpieces are installed on the upper surface of the above-mentioned carrier plate 300.

[0035] A plurality of adsorption holes 301 are formed on the upper surface of the above-mentioned carrier plate 300, and the adsorption holes 301 are communicated with a vacuum generator through a pipeline.

[0036] The working principle of the present utility model is as follows:

[0037] 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 workpiece contacts the upper surface of the carrier plate, and the upper surface contacts the lower surface of the cover plate;

[0038] Since the cover plate generally uses a metal part and has a large self-weight, therefore, under the action of its own pressure, the workpiece can be initially kept in surface contact with the cover plate and the carrier plate above and below it; then, by starting a vacuum pump or a vacuum generator, a gas flow path from the adsorption holes on the upper surface of the carrier plate to the vacuum pump or the vacuum generator is generated, so as to generate an adsorption force on the cover plate above the workpiece, and further enhance the downward acting force on the cover plate, thereby realizing stable pressing of the workpiece;

[0039] Then, the workpiece is subjected to circumferential milling processing by a CNC tool;

[0040] When the processing is completed: the push block is driven by the opening and closing cylinder to move up to a high position, so that the rotating plate that rotates as the push block moves up rotates to the horizontal, and the clamping assembly installed on the rotating plate rotates to above the workpiece to be clamped on the cover plate; at this time, the connecting rod rotates to the vertical state, and the pin shaft moves to the upper end of the first guiding part of the guiding groove and the end of the strip-shaped hole on the push block away from the carrier plate;

[0041] Then, through the clamping cooperation between the clamping assembly and the workpiece to be clamped, stable clamping of the entire cover plate is realized. Here, the clamping assembly and the workpiece to be clamped do not belong to the inventive point of this patent, and can be obtained by outsourcing specifically, or the solution in the applicant's prior application (application number 2024102325213) can also be adopted, which will not be elaborated here;

[0042] Turn off the vacuum pump or vacuum generator, and drive the push block to move downward to the low position through the opening and closing cylinder. During this process, the pin shaft first moves vertically downward along the first guiding portion of the guiding groove. The rotating plate rotatably connected to the push block by the pin shaft then rotates from the horizontal position to the vertical (90°) position, and at the same time drives the clamped cover plate to also rotate from the horizontal position to the vertical position; under the action of the downward pulling force of the push block, the pin shaft continues to move downward and enters into the second guiding portion of the guiding groove, and moves along the inclined second guiding portion to the lower end of the second guiding portion. During this process, the pin shaft also moves from one end close to the carrier plate to the other end in the strip-shaped hole of the push block, and the rotating plate also continues to rotate outward along with the movement of the pin shaft, and the cover plate also continues to rotate outward to the 110° position, so as to be away from the workpiece to be processed, facilitating the CNC tool to perform one-time processing on the periphery of the workpiece to be processed, and improving the processing efficiency and convenience.

[0043] When the above-mentioned notebook upper cover presses the cover plate, while realizing the automatic opening and closing of the cover plate, it can avoid the interference of the rotating structure on the whole processing process, especially on the milling process of the workpiece, facilitating the one-time continuous processing of the periphery of the workpiece, and improving the processing efficiency, convenience and consistency.

[0044] The above embodiments are only used to illustrate the technical concept and characteristics of the present invention, and the purpose is to enable those skilled in the art to understand the content of the present invention and implement it accordingly, and cannot be used to limit the protection scope of the present invention. Any equivalent changes or modifications made according to the spirit of the present invention should be covered within the protection scope of the present invention.
