Description

Technical Field

[0001] This invention relates to a mirror-finishing method for a notebook computer top cover, belonging to the field of electronic product processing. Background Technology

[0002] Fixtures are indispensable in the field of mechanical manufacturing. Their purpose is to repeat specific actions, accurately process high-precision products, and make workpiece dimensions more precise. In recent years, the emergence and development of high-performance, high-precision CNC machine tools have enabled the application of CNC high-gloss machining technology in the field of laptop casing processing.

[0003] During the manufacturing process of laptop casings, various through holes are required to facilitate the installation or connection of internal components. To ensure an aesthetically pleasing appearance, after the through holes are created, appropriate surface finishing is typically performed before applying a high-gloss finish. When using a high-gloss finish to process laptop casings, the casing must be precisely and stably mounted on the machine tool using a specialized fixture before any actual processing can begin.

[0004] In the existing technology, the high-gloss wall of the laptop shell needs to be processed with a high polishing surface. Traditional fixtures use a local multi-point clamping method for the shell, which has poor locking position accuracy, insufficient stability during machining, and the locking operation is also relatively cumbersome. Summary of the Invention

[0005] The purpose of this invention is to provide a mirror-finishing method for a laptop top cover. This method allows the two protrusions on the pressure block to apply pressure evenly to the movable plate, further improving the positional accuracy and pressure balance of fixing the laptop casing.

[0006] To achieve the above objectives, the technical solution adopted by the present invention is: a mirror processing method for a notebook top cover, used for notebook shell processing, based on a processing fixture, the processing fixture including: a substrate and a carrier plate disposed on the upper surface of the substrate, and also having a cover plate rotatably disposed and two pressure plates each rotatably disposed on the left and right sides of the cover plate. When in a 90° state, the cover plate and the pressure plates are each vertically disposed on the rear side of the carrier plate. The front and rear end faces of the cover plate each have at least one outwardly extending protrusion. A support column is installed on the carrier plate and the substrate and directly below each protrusion.

[0007] Below the cover plate is a movable plate for pressing and contacting the upper surface of the notebook shell. The movable plate has at least two through-holes. A guide sleeve is embedded in each of the mounting holes. The upper end of a bolt passes through the guide sleeve and is threaded to the cover plate. A spring is provided between the head of the lower end of the bolt and the inner flange formed on the inner wall of the upper end of the guide sleeve.

[0008] Each of the pressure plates has a pin rotatably mounted on its end face facing the cover plate. One end of the pin is embedded in the pressure plate, and a pressure block is fixedly mounted on the other end of the pin. The lower surfaces of the front and rear ends of the pressure block have a downward protrusion. The lower end face of the protrusion is lower than the lower surface of the pressure plate. The upper surface of the cover plate has a clearance through hole corresponding to the pressure block on the left and right sides respectively.

[0009] The mirror finishing method for the laptop cover includes the following steps:

[0010] Step 1: Position the cover plate and two pressure plates at 90°, place the laptop shell to be processed on the carrier plate, and make the upper surface of the carrier plate fit and contact the lower surface of the laptop shell.

[0011] Step 2: Drive the cover plate to rotate until the lower surface of the protrusion on the cover plate contacts the upper end face of the support column. At this time, the cover plate is in a 0° state and is set parallel to the top of the laptop shell. Under the action of the spring, there is a gap between the lower surface of the movable plate installed on the cover plate and the upper surface of the laptop shell.

[0012] Step 3: Drive the two pressure plates to rotate until the lower surface of the movable plate is in pressure contact with the upper surface of the laptop shell. At this time, the pressure plates are tilted relative to the upper surface of the laptop shell, and the rotatable pressure block is parallel to the upper surface of the laptop shell. The two protrusions on the pressure block that pass through the clearance hole at the bottom are pressed against the upper surface of the movable plate.

[0013] Step 4: High-speed milling is performed on the area to be processed on the laptop casing using a high-speed rotating cutter head.

[0014] The following are further improvements to the above technical solution:

[0015] 1. In the above scheme, there are four protrusions and four support columns.

[0016] 2. In the above scheme, the upper surface of the pressure block is provided with at least one arc-shaped groove extending perpendicular to the length direction of the pressure block, one end of which is embedded in the limiting block installed on the upper part of the pressure plate, and the other end of which is embedded in the arc-shaped groove. The area where the limiting block is embedded in the arc-shaped groove is the arc-shaped block area that matches the arc-shaped groove.

[0017] 3. In the above scheme, a base plate is provided below the substrate, and each of the four corners of the base plate is connected to the substrate through a connecting post.

[0018] 4. In the above solution, the upper surface of the carrier board is provided with a plurality of limiting blocks that cooperate with the through holes on the laptop shell.

[0019] 5. In the above scheme, the six mounting holes are evenly distributed on the movable plate.

[0020] 6. In the above solution, the movable plate further includes a stacked upper base layer and a lower elastic layer, the lower surface of which is used for pressing contact with the upper surface of the notebook casing.

[0021] 7. In the above scheme, an outer flange is formed on the lower outer wall of the guide sleeve, and the outer flange is embedded in an annular groove that is opened on the movable plate and communicates with the mounting hole.

[0022] 8. In the above scheme, the upper part of the guide sleeve can be embedded in a groove opened on the lower surface of the cover plate.

[0023] Due to the application of the above technical solution, the present invention has the following advantages compared with the prior art:

[0024] 1. The present invention provides a mirror surface processing method for a notebook computer top cover. This method utilizes a combination of an automatically opening and closing cover plate and a pressure plate. First, the cover plate is moved directly above the notebook casing, maintaining a certain gap between the movable plate on the cover plate and the notebook casing to prevent damage. Then, the pressure block on the pressure plate presses the movable plate down onto the notebook casing, achieving automatic pressure on the entire outer surface of the area to be processed on the casing. This method maintains stability while preventing damage to the casing, thus ensuring the effectiveness of the tool processing surface and avoiding reduced yield due to tool marks caused by vibration.

[0025] 2. The mirror processing method for the notebook top cover of the present invention, while achieving automatic and stable pressing, further includes a pin shaft rotatably installed on the end face of the pressing plate facing the cover plate. A pressing block is fixedly installed on the other end of the pin shaft, which is embedded in the pressing plate at one end. The lower surface of the pressing block at both the front and rear ends has a downward protrusion. The lower end face of the protrusion is lower than the lower surface of the pressing plate. The protrusion on the pressing block, which can pass through the clearance hole, presses against the upper surface of the movable plate, so that the lower surface of the movable plate presses against the upper surface of the notebook shell. When the pressing plate is tilted and pressed down, the rotatable pressing block can adaptively adjust to remain parallel to the upper surface of the notebook shell, and make the two protrusions apply pressure evenly to the movable plate, further improving the positional accuracy and pressure uniformity of fixing the notebook shell.

[0026] 3. The mirror processing method for the notebook top cover of the present invention, while achieving automatic and stable pressing, further provides at least one outwardly extending protrusion on each of the front and rear end faces of the cover plate. A support column is installed on the carrier plate and the substrate, directly below each protrusion. When in the 0° state, the lower surface of the protrusion on the cover plate contacts the upper end face of the support column, so that the cover plate is parallel to the top of the notebook shell. This can avoid damage to the notebook shell caused by the moving plate hitting the cover plate during repeated rapid opening and closing, and can also ensure that the moving plate remains horizontal before the pressure block applies pressure to the moving plate, thereby ensuring the stability and uniformity of the pressing force on the notebook shell surface and improving the processing quality.

[0047] Below the cover plate 3, there is a movable plate 5 for pressing and contacting the upper surface of the notebook housing 100. The movable plate 5 has at least two vertically penetrating mounting holes 6. A guide sleeve 7 is embedded in each mounting hole 6.

[0049] The mirror finishing method for the laptop cover includes the following steps:

[0050] Step 1: Place the cover plate 3 and the two pressure plates 4 at a 90° angle, and place the notebook shell 100 to be processed on the carrier plate 2, so that the upper surface of the carrier plate 2 is in contact with the lower surface of the notebook shell 100.

[0051] Step 2: Drive the cover plate 3 to rotate until the lower surface of the protrusion 14 on the cover plate 3 contacts the upper end face of the support column 15. At this time, the cover plate 3 is in a 0° state and is parallel to the top of the notebook housing 100. Under the action of the spring 9, there is a gap between the lower surface of the movable plate 5 installed on the cover plate 3 and the upper surface of the notebook housing 100.

[0052] Step 3: Drive the two pressure plates 4 to rotate until the lower surface of the movable plate 5 is in pressure contact with the upper surface of the notebook housing 100. At this time, the pressure plates 4 are in an inclined state relative to the upper surface of the notebook housing 100, and the rotatable pressure block 10 is parallel to the upper surface of the notebook housing 100. The two protrusions 12 on the pressure block 10, which passes through the clearance hole 301 at the bottom, are in pressure contact with the upper surface of the movable plate 5.

[0053] Step 4: High-speed milling is performed on the area to be processed on the notebook casing 100 using a high-speed rotating cutter head.

[0054] A base plate 31 is provided below the aforementioned substrate 1, and each of the four corners of the base plate 31 is connected to the substrate 1 through a connecting post 32.

[0055] The upper surface of the aforementioned carrier plate 2 is provided with a plurality of limiting blocks 34 that cooperate with the through holes on the notebook housing 100;

[0056] The six mounting holes 6 are evenly distributed on the movable plate 5;

[0057] The aforementioned movable plate 5 further includes a stacked upper base layer 51 and a lower elastic layer 52, the lower surface of which is used for pressing contact with the upper surface of the notebook housing 100.

[0058] An outer flange 72 is formed on the lower outer wall of the guide sleeve 7. The outer flange 72 is embedded in the annular groove 53 that is opened on the movable plate 5 and communicates with the mounting hole 6.

[0059] The upper part of the aforementioned guide sleeve 7 can be inserted into the groove 302 opened on the lower surface of the cover plate 3;

[0060] Each of the aforementioned cover plate 3 and pressure plate 4 is provided with a cylinder 17 at its rear. Each of the aforementioned cylinders 17 is mounted on the lower surface of the base plate 1 via a mounting plate 16. The upper end of the piston rod of each of the aforementioned cylinders 17 can pass through the clearance hole on the base plate 1 and is equipped with a connecting block 18. The other end of the connecting block 18, which is hinged to the upper end of the piston rod, is fixedly connected to the rear end of the corresponding cover plate 3 or pressure plate 4. A fixing seat 19 is provided between the piston rod and the cover plate 3 and pressure plate 4. A connecting piece 20 is hingedly mounted on the left and right surfaces of the fixing seat 19. The upper end of the connecting piece 20, which is connected to the fixing seat 19 at its lower end, is hingedly connected to the left and right surfaces of the middle part of the connecting block 18.

[0061] The lower part of the aforementioned fixing base 19 passes through the clearance hole on the substrate 1 and is fixedly connected to the upper surface of the mounting plate 16.

[0062] When using the above-mentioned mirror processing method for the laptop top cover, the combination of an automatically opening and closing cover plate and a pressure plate is used. First, the cover plate is moved to the top of the laptop shell, and a certain gap is maintained between the movable plate on the cover plate and the laptop shell so as not to damage the shell. Then, the pressure block on the pressure plate presses the movable plate down onto the laptop shell, thereby achieving automatic pressing of the entire outer surface of the area to be processed on the shell. This method can maintain the stability of the pressing without damaging the shell, thus ensuring the effect of the tool processing surface and avoiding the reduction of the yield rate due to tool marks caused by vibration.

[0063] Furthermore, a pin is rotatably mounted on the end face of the pressure plate facing the cover plate. A pressure block is fixedly mounted on the other end of the pin, which is embedded in the pressure plate. The lower surface of the front and rear ends of the pressure block has a downward protrusion. The lower end face of the protrusion is lower than the lower surface of the pressure plate. The protrusion on the pressure block, which can pass through the clearance hole, presses against the upper surface of the movable plate, so that the lower surface of the movable plate presses against the upper surface of the laptop shell. When the pressure plate is tilted down, the rotatable pressure block can adaptively adjust to keep parallel to the upper surface of the laptop shell, and make the two protrusions apply pressure evenly to the movable plate, further improving the positional accuracy and pressure balance of fixing the laptop shell.

[0064] Furthermore, each of the front and rear end faces of the cover plate has at least one outwardly extending protrusion. A support column is installed on the carrier plate and substrate, directly below each protrusion. When in the 0° state, the lower surface of the protrusion on the cover plate contacts the upper end face of the support column, so that the cover plate is parallel to the top of the laptop shell. This can prevent the movable plate from hitting the laptop shell and causing damage during repeated rapid opening and closing of the cover plate, and can also ensure that the movable plate remains horizontal before the pressure block applies pressure to the movable plate, thereby ensuring the stability and uniformity of the pressure on the laptop shell surface and improving the processing quality.
