Description

Technical Field

[0001] This invention relates to the field of milling technology, specifically to a milling apparatus for a notebook computer casing mold. Background Technology

[0002] The laptop casing serves as the carrier and protective shell for functional components such as the motherboard and processor. It integrates a series of important aspects, including process design, materials, volume control, weight control, heat dissipation control, robustness and security, and environmental friendliness. Laptop casing materials include ABS engineering plastics, magnesium-aluminum alloys, titanium alloys, carbon fiber alloys, and polycarbonate (PC), among which aluminum-magnesium alloys are the most common and the most widely used laptop casing materials.

[0003] The aluminum-magnesium alloy casing needs to be milled to achieve the required dimensions for the laptop during manufacturing. Milling equipment, also known as cutting equipment, is used in this process, characterized by high cutting speed and narrow kerf. An industrial-grade machine tool design ensures high-speed and stable laser cutting. By selecting fiber lasers of varying power, it can perform high-speed, precision cutting and drilling of various metals and materials. Combined with a following dynamic focusing device, it maintains consistent cutting quality throughout the process.

[0004] Existing milling equipment uses clamping devices to fix the workpiece during the cutting process. However, the size of the workpiece is not fixed and needs to be adjusted at any time. During the adjustment process, the clamping jaws need to be opened manually, the workpiece needs to be removed, and then the equipment needs to be adjusted. Moreover, there are more than one clamping jaw, and multiple jaws need to be operated separately, which is a cumbersome process. Summary of the Invention

[0005] To address the shortcomings of the aforementioned background technology, the present invention provides a technical solution for a milling device for a laptop casing mold. The device uses a clamping mechanism to clamp workpieces of different sizes and heights, facilitating quick pick-up and drop of workpieces and solving the problems mentioned in the background technology.

[0006] The present invention provides the following technical solution: a milling device for a laptop shell mold, comprising a worktable, a panel fixed to the top of the worktable; a frame, frames fixed to both sides of the worktable; a milling head, a milling head for cutting slidably mounted on the top of the frame; a placement rack, a placement rack slidably connected to the top of the panel, and also including a workpiece, the top of the placement rack being used for placing the workpiece; and a clamping mechanism, clamping mechanisms provided on both sides of the top of the worktable, which can clamp workpieces of different sizes and heights, facilitating quick pick-up and drop of workpieces.

[0007] As a preferred embodiment of the present invention, the clamping mechanism includes clamping claws, which are symmetrically connected to both sides of the top of the worktable; a fixing block I, which is fixed to both sides of the top of the worktable and located on one side of the clamping claw, with one side of the top of the fixing block I being inclined; a rotating wheel, with a U-shaped groove on the lower surface of the clamping claw, and a rotating wheel rotatably connected to the two side walls of the U-shaped groove; a base, with a base slidably connected to both sides of the clamping claw, and the bottom of the base slidably connected to both sides of the top of the worktable; a fixing rod, with a fixing rod fixed to one side surface of the base; a hinge rod, with a hinge rod hinged between the two fixing rods; a fixing plate, with a fixing plate fixed to the front surface of the worktable; a rotating cylinder, with a rotatable rotating cylinder passing through the fixing plate, one end of the rotating cylinder extending to the back of the worktable; a button groove, with symmetrical button grooves at both ends of the outer wall of the rotating cylinder; and two slots, with two slots formed on the lower surface of the clamping claw near the rotating cylinder.

[0008] As a preferred embodiment of the present invention, a fixing block II is fixed at the hinge point in the middle of the hinge rod, and an insert block II is fixed at the bottom of the fixing block II, and the insert block II is always inserted into the button groove.

[0009] As a preferred embodiment of the present invention, when the clamping claw moves toward the fixed block I, the inclined surface of the fixed block I contacts the rotating wheel, and the base located below the slot has a semi-closed structure.

[0010] As a preferred embodiment of the present invention, a support frame is fixed to the top of the workbench, and a telescopic rod is fixed to the top of the support frame. The telescopic rod is telescopic in the middle, and both ends of the telescopic rod are fixed with insert blocks I. The insert blocks I have a U-shaped structure and a sloping bottom side. One end of the insert block I corresponds to the slot.

[0011] As a preferred embodiment of the present invention, the slot is internally connected to a roller, and when the clamping claw moves toward the fixed plate, the inclined surface on one side of the bottom of the insertion block I contacts the roller. The two ends of the telescopic rod are fixed to the bottom of the placement frame via connecting rods near the insertion block I.

[0012] As a preferred embodiment of the present invention, the bottom of the rotating cylinder is supported by a supporting arc plate, the outer wall of the rotating cylinder is in contact with but not connected to the supporting arc plate, the supporting arc plate has a semi-circular structure, the supporting arc plate is fixed on the top of the workbench, a rotating circular block is fixed at one end of the rotating cylinder through the fixed plate, a plurality of first slots are provided on the surface of the fixed plate, and a plug shaft is slidably connected inside the rotating circular block by a spring, the spring being located inside the rotating circular block and sleeved on the end of the plug shaft.

[0013] As a preferred embodiment of the present invention, the circumference of the first slot is an arc-shaped surface, and the end of the insertion shaft located outside the rotating block is a hemispherical structure.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] The rotating wheel contacts the inclined surface at the top of the fixed block I, causing its clamping jaws to move upward on the base, thus lifting the clamping jaws off the surface of the workpiece. This facilitates the removal of the workpiece and makes the operation convenient. It eliminates the need to operate multiple clamping jaws separately, allowing for easy adjustment of the clamping mechanism according to the size of the workpiece during cutting and quick removal and placement of the workpiece, thus simplifying the operation.

[0016] When insert I is inserted into the slot, the inclined surface at the bottom of insert I contacts the roller. The roller rolls due to the friction generated by the contact with insert I, so that insert I is not obstructed when inserted into the slot and wear is reduced. Attached Figure Description

[0026] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0027] Please see Figure 1-7As shown, a milling device for a laptop casing mold includes a worktable 1 with a panel 5 fixed to its top; a frame 2 with frames 2 fixed to both sides of the worktable 1; a milling head 3 slidably mounted on the top of the frame 2 for cutting; and a placement rack 8 slidably connected to the top of the panel 5. It also includes a workpiece 6, with the top of the placement rack 8 used for placing the workpiece 6. The device is characterized by a clamping mechanism, with clamping mechanisms provided on both sides of the top of the worktable 1, which can clamp the workpiece. The worktable 1 is equipped with clamping mechanisms for different sizes and heights, facilitating quick loading and unloading of workpieces 6. The clamping mechanism includes clamping jaws 4, symmetrically connected to both sides of the top of the worktable 1; a fixing block I 401, fixed to both sides of the top of the worktable 1 and located on one side of the clamping jaws 4, with one side of the top of the fixing block I 401 having an inclined surface; a rotating wheel 405, with a U-shaped groove 409 on the lower surface of the clamping jaws 4, through which the rotating wheel 405 is rotatably connected; and a base 402 for clamping... The claw 4 has a base 402 slidably connected to both sides, and the bottom of the base 402 is slidably connected to the top sides of the worktable 1; a fixed rod 406 is fixed to one side surface of the base 402; a hinge rod 407 is hinged between the two fixed rods 406; a fixed plate 703 is fixed to the front surface of the worktable 1; a rotating cylinder 7 is rotatable and passes through the fixed plate 703, with one end of the rotating cylinder 7 extending to the back of the worktable 1; and a button groove 701 is provided for the rotating cylinder 7. The outer wall has axially symmetrical grooves 701 at both ends; slots 403, two slots 403 are opened on the surface below the gripper 4 near the rotating cylinder 7; a fixing block II 408 is fixed at the hinge point in the middle of the hinge rod 407, and an insert block II is fixed at the bottom of the fixing block II 408, and the insert block II is always inserted into the groove 701; when the gripper 4 moves near the fixing block I 401, the inclined surface of the fixing block I 401 contacts the rotating wheel 405, and the surface of the base 402 below the slot 403 is a semi-closed structure.

[0028] During operation, if the workpiece 6 being cut is small, the placement rack 8 can be moved towards the center of the panel 5 to gradually reduce the distance between them. Then, the workpiece 6 to be cut is placed on top of the placement rack 8. The rotating cylinder 7 is then rotated by rotating block 702. For smaller workpieces 6, the rotating cylinder 7 rotates clockwise, causing the insert block II inside the button groove 701 to gradually reduce the included angle of the hinge rod 407. As the included angle of the hinge rod 407 gradually decreases, the ends of the hinge rod 407 pull the fixed rods 406 on both sides of the worktable 1 and the base 402 towards the workpiece 6. The base 402 then moves the clamping jaws 4 in the same direction. When the insert block I 404 is inserted into the slot 403, the inclined surface at the bottom of the insert block I 404 contacts the roller 410, causing the clamping claw 4 to descend on the base 402, clamping it onto the surface of the workpiece 6 and fixing it there. If the workpiece 6 being cut is large, the placement frame 8 can be moved closer to the clamping claw 4 to increase the distance between the two placement frames 8. When the placement frame 8 moves, the connecting rod 801 simultaneously drives the telescopic rod 4041 to move in the same direction. Then, the rotating block 702 and the rotating cylinder 7 continue to rotate clockwise to move the clamping claw 4 closer to the workpiece 6, and the insert block I 404 is inserted into the slot 403 to fix it there.

[0029] When removing workpiece 6, the rotating block 702 and the rotating cylinder 7 can be rotated counterclockwise to move the insert block II on the rotating cylinder 7, gradually opening the hinge rod 407 and increasing its included angle. This pushes the fixed rod 406 and the base 402 to move away from the worktable 1. During the movement, the rotating wheel 405 contacts the inclined surface at the top of the fixed block I 401, causing the clamping claw 4 to move upward on the base 402, so that the clamping claw 4 leaves the surface of workpiece 6, making it easy to remove workpiece 6. The operation is convenient and does not require separate operation of multiple clamping claws 4. It is convenient to adjust the clamping mechanism according to the size of workpiece 6 during cutting and to quickly pick up and put down workpiece 6, making the operation convenient.

[0030] It should be noted that the end of the insert block I 404 must protrude beyond the placement frame 8. When the workpiece 6 is placed on top of the placement frame 8, both sides will protrude beyond the edge of the placement frame 8 but not beyond the end of the insert block I 404. When the placement frame 8 is moved, the telescopic rod 4041 moves in the same direction as the placement frame 8. The clamping claw 4 moves gradually closer to the workpiece 6 so that the insert block I 404 is inside the insertion slot 403. There is space inside the slot 403 for the insert block I 404 to move, so the clamping of workpieces of different sizes can be established.

[0031] Please see Figure 5-8As shown, in a specific embodiment of the present invention, a support frame 411 is fixed to the top of the workbench 1, and a telescopic rod 4041 is fixed to the top of the support frame 411. The telescopic rod 4041 is telescopic in the middle, and both ends of the telescopic rod 4041 are fixed with insert blocks I 404. The insert blocks I 404 have a U-shaped structure and one side of the bottom is sloping. One end of the insert block I 404 corresponds to the slot 403. A roller 410 is rotatably connected inside the slot 403. When the clamping claw 4 moves toward the fixed plate 703, the sloping side of the bottom of the insert block I 404 contacts the roller 410. The two ends of the telescopic rod 4041 are connected to the placement via connecting rods 801 near the insert blocks I 404. The bottom of the frame 8 is fixed; the bottom of the rotating cylinder 7 is supported by the supporting arc plate 704. The outer wall of the rotating cylinder 7 is in contact with but not connected to the supporting arc plate 704. The supporting arc plate 704 has a semi-circular structure and is fixed to the top of the workbench 1. One end of the rotating cylinder 7 is fixed with a rotating block 702 through the direction of the fixed plate 703. The surface of the fixed plate 703 has multiple first slots 705. The rotating block 702 is slidably connected to the insert shaft 706 through a spring. The spring is located inside the rotating block 702 and is sleeved on the end of the insert shaft 706. The circumference of the slot 705 is an arc surface, and the end of the insert shaft 706 located outside the rotating block 702 has a hemispherical structure.

[0032] When the insert block I 404 is inserted into the slot 403, the inclined surface at the bottom of the insert block I 404 contacts the roller 410. The roller 410 rolls due to the friction generated by the contact with the insert block I 404, so that the insert block I 404 is not obstructed when it is inserted into the slot 403 and wear is reduced. When the rotating block 702 rotates, the end of the insert shaft 706 deforms and contracts through the spring when it exits the first slot 705, so that the insert shaft 706 moves into the interior of the rotating block 702. The first slot 705 has an arc-shaped circumference and the insert shaft 706 has a hemispherical end structure. The insert shaft 706 reduces friction when it exits the slot 705, so as to avoid jamming when rotating the rotating block 702. The insertion of the insert shaft 706 into the first slot 705 fixes the rotation angle of the rotating block 702 and the distance of movement of the clamping claw 4.
