Description

Technical Field

[0001] This utility model relates to the field of notebook hinge manufacturing technology, specifically to an automatic milling machine with high processing efficiency for notebook hinge production. Background Technology

[0002] Laptop hinge production is one of the core processes in laptop manufacturing. Its quality directly affects the user experience (such as the smoothness of screen opening and closing and angular stability) and the overall lifespan of the product (such as wear resistance and structural reliability). As a key component connecting the laptop body and the screen, the hinge must have characteristics such as high precision, high strength, and low friction to meet the needs of frequent opening and closing (usually requiring tens of thousands of opening and closing tests). Among these processes, milling is one of the key steps in hinge processing. Its main function is to remove hinge material through machining to form a plane or groove of a specific shape.

[0003] An existing patent (publication number: CN211192193U) discloses a milling machine for reducing debris splashing. It includes a machine base, a support block mounted on the upper surface of the machine base, a drive motor mounted on the upper surface of the support block, a horizontal rotating shaft connected to the drive motor, a milling saw blade coaxially fixed on the rotating shaft, a receiving box with an open top below the milling saw blade, the receiving box being mounted on the upper surface of the machine base, a horizontal guide rail inside the receiving box, a tooling frame slidably mounted on the guide rail, a power mechanism connected to the tooling frame to drive it to slide along the guide rail, and a protective cover mounted on the upper end of the support block. The protective cover is arc-shaped or U-shaped and located on the outer wall of the rotating shaft and the milling saw blade. The protective cover has processing holes on its side wall facing the tooling frame corresponding to the milling saw blade. This invention can prevent debris splashing during the milling process, reducing safety hazards and environmental pollution.

[0004] The above-mentioned milling machine can prevent the flying of debris during the milling process of the workpiece, which is less likely to cause safety hazards and reduce pollution to the surrounding environment. However, each time the spindle is milled, the operator needs to place the spindle on the mounting frame. After the processing is completed, the spindle is still in the work position and the material needs to be removed manually, which is not convenient for continuous milling of the spindle. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides an automatic milling machine with high processing efficiency for notebook computer hinge production, which has advantages such as automatic loading and unloading, and solves the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: an automatic milling machine with high processing efficiency for notebook hinge production, comprising a processing platform and a processing base, wherein the processing base is fixedly installed on the central area of ​​the upper surface of the processing platform, the processing base has an L-shaped structure, and a milling component for milling the hinge is provided at its upper end;

[0007] A sliding groove is provided between the processing platform and the processing base. A convex-shaped support plate is slidably connected inside the sliding groove. A clamping assembly that cooperates with the support plate to clamp the rotating shaft is provided on the upper surface of the processing base. Cooling assemblies for cooling the rotating shaft are also provided on both sides of the processing base. An inclined feed chute is fixedly provided on the side of the processing platform. The feed chute is connected to the sliding groove. An inclined feed frame that corresponds to the position of the feed chute is fixedly connected to the side of the processing base.

[0008] On both sides of the upper surface of the processing base along the length direction, there are fixed frames with a triangular structure. The upper surfaces of the two fixed frames are fixedly connected with elastic rods with an arc structure. A ramp is opened on one side of the upper end of the two fixed frames. A bearing plate is fixedly connected between the two fixed frames, and the bearing plate corresponds to the position of the two ramps.

[0009] Furthermore, the inner bottom wall of the processing platform is fixedly connected to two symmetrically arranged cylinders, and the output ends of the two cylinders are fixedly connected to the bottom end of the support plate.

[0010] With the above scheme, the two cylinders can be synchronously pushed by the same solenoid valve to rise or fall vertically in the slide. When the support plate rises, it can push the rotating shaft to the milling area.

[0011] Furthermore, the clamping assembly includes a sliding groove on the upper surface of the processing base, and an L-shaped clamping plate is slidably connected inside the sliding groove. The clamping plate and the side of the bearing plate corresponding to each other are provided with V-shaped clamping grooves.

[0012] The above solution allows for the clamping of the rotating shaft by setting a clamping groove. The V-shaped clamping groove adapts to rotating shafts of different diameters, ensuring stable clamping and precise positioning, effectively preventing shaking during processing.

[0013] Furthermore, the clamping assembly also includes a set of springs fixedly connected between the bottom end of the clamping plate and the inner bottom wall of the sliding groove. The bottom end of the clamping plate has a T-shaped structure, and the sliding groove has an inverted T-shaped structure. The two are adapted to each other. An air inlet groove is provided on the upper surface of the processing base, and the other end of the air inlet groove is connected to the sliding groove.

[0014] With the above scheme, the spring can drive the clamping plate to reset under the action of the spring reset force. During the reset process, the clamping plate can squeeze the air inside the chute, so that the air is discharged through the air inlet groove. This process takes a certain amount of time. Therefore, when the bearing plate descends vertically in the chute, the rotating shaft can separate from the clamping plate. When the rotating shaft contacts the elastic rod, the rotating shaft can be pushed out by the elastic rod and roll along the slope onto the bearing plate to realize the unloading.

[0015] Furthermore, the cooling assembly includes multiple clamping plates fixedly connected at right angles on the upper surface of the processing base. A protective frame is slidably inserted between each pair of corresponding clamping plates. A drain pipe is fixedly installed on one side of each of the two protective frames. A nozzle is fixedly connected to one end of each of the two drain pipes. The opposite ends of the two drain pipes are fixedly connected to the main body in the outside.

[0016] The above-mentioned solution allows the protective frame to shield the milled area and prevent splashing, while the drainage pipe and nozzle work together to deliver external refrigerant to the milled area and cool the milled part of the shaft.

[0017] Furthermore, the cooling assembly also includes receiving grooves opened at both ends along the length direction on the upper surface of the processing base. The inner walls of both receiving grooves are equipped with filter screens. Both ends of the processing base along the length direction are equipped with return pipes that communicate with the receiving grooves. Both return pipes are connected to external equipment for storing refrigerant.

[0018] The above scheme allows for the recycling and reuse of used refrigerant through a receiving tank and return pipe, while the filter screen can remove residues from the refrigerant.

[0019] Furthermore, the milling assembly includes an electric push rod fixedly installed on the upper end of the processing base. A shaped frame is fixedly installed on the output end of the electric push rod. Rotary rods are rotatably connected to both ends of the shaped frame. A set of milling saw blades is fixedly connected to the circumferential surface of each of the two rotary rods. The ends of the two rotary rods corresponding to the processing base are connected to the belt drive via pulleys. One of the rotary rods is fixedly connected to the output end of an external motor.

[0020] With the above scheme, the two rotating rods can rotate synchronously under the drive of the belt, so that the two milling saw blades can mill the two ends of the rotating shaft, and the electric push rod can control the height of the milling saw blades by pushing the irregular frame.

[0021] Compared with the prior art, the technical solution of this utility model has the following beneficial effects:

[0022] This high-efficiency automatic milling machine for notebook hinge production features a feeding frame and feeding chute that utilizes gravity to automatically feed the hinge. During the hinge conveying process, an elastic rod not only contacts and pushes the hinge to keep its center centered, ensuring that the milling allowance at both ends of the hinge is the same and guaranteeing consistent milling length, but also, after the hinge is milled, the elastic rod pushes the hinge off the support plate during the plate reset process, allowing the hinge to roll along the ramp into the support plate, achieving automatic unloading.

[0036] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0037] Please see Figures 1-5 This embodiment describes an automatic milling machine with high processing efficiency for producing notebook hinges, which includes a processing platform 1 and a processing base 2. The processing base 2 is fixedly installed in the central area of ​​the upper surface of the processing platform 1. The processing base 2 has an L-shaped structure and a milling component 3 for milling the hinge is provided at its upper end.

[0038] A sliding groove 4 is provided between the processing platform 1 and the processing base 2. A convex-shaped support plate 5 is slidably connected inside the sliding groove 4. A clamping assembly 6 is provided on the upper surface of the processing base 2 to clamp the rotating shaft in cooperation with the support plate 5. Cooling assemblies 7 for cooling the rotating shaft are also provided on both sides of the processing base 2. An inclined feeding groove 8 is fixedly provided on the side of the processing platform 1. The feeding groove 8 is connected to the sliding groove 4. An inclined feeding frame 9 corresponding to the position of the feeding groove 8 is fixedly connected to the side of the processing base 2. The inclined feeding groove 8 allows the rotating shaft in the feeding groove 8 to slide to the upper end of the support plate 5 under gravity after the support plate 5 slides vertically downward in the sliding groove 601, thereby realizing automatic feeding of the rotating shaft.

[0039] On both sides of the upper surface of the processing base 2, there are fixed frames 10 with a triangular structure. The upper surfaces of the two fixed frames 10 are fixedly connected with elastic rods 11 with an arc structure. A ramp 12 is opened on one side of the upper end of the two fixed frames 10. A bearing plate 13 is fixedly connected between the two fixed frames 10. The bearing plate 13 corresponds to the two ramps 12. The elastic rods 11 can contact the two ends of the rotating shaft and push the rotating shaft after the bearing plate 5 pushes the rotating shaft out, so that the milling allowance at both ends of the rotating shaft is the same, and the milling length is consistent. Two symmetrically arranged cylinders 14 are fixedly connected to the inner bottom wall of the processing platform 1. The output ends of the two cylinders 14 are fixedly connected to the bottom end of the bearing plate 5. The two cylinders 14 can push the bearing plate 5 vertically up or down in the slide 4 under the control of the same solenoid valve. When the bearing plate 5 rises, it can push the rotating shaft to the milling area.

[0040] The clamping assembly 6 includes a sliding groove 601 formed on the upper surface of the machining base 2. An L-shaped clamping plate 602 is slidably connected inside the sliding groove 601. Each clamping plate 602 has a V-shaped clamping groove 603 on its corresponding side to the support plate 5. The clamping grooves 603 allow for clamping of the rotating shaft, and the V-shaped grooves 603 adapt to rotating shafts of different diameters, ensuring stable clamping and precise positioning, effectively preventing shaking during machining. The clamping assembly 6 also includes a set of springs 604 fixedly connected between the bottom end of the clamping plate 602 and the inner bottom wall of the sliding groove 601. The bottom end of the clamping plate 602 has a T-shaped structure, and the sliding groove 601 has an inverted T-shaped structure. The two are compatible. The upper surface of the processing base 2 is provided with an air inlet groove 605. The other end of the air inlet groove 605 is connected to the sliding groove 601. The spring 604 can drive the clamping plate 602 to reset under the action of the spring 604's reset force. During the reset process, the clamping plate 602 can squeeze the air inside the sliding groove 4, so that the air is discharged through the air inlet groove 605. This process takes a certain amount of time. Therefore, when the bearing plate 5 descends vertically in the sliding groove 4, the rotating shaft can separate from the clamping plate 602. When the rotating shaft contacts the elastic rod 11, the rotating shaft can be pushed out by the elastic rod 11 and roll along the slope 12 onto the bearing plate 13 to realize the unloading.

[0041] The cooling assembly 7 includes multiple clamping plates 701 fixedly connected at right angles on the upper surface of the machining base 2. A protective frame 702 is slidably inserted between every two corresponding clamping plates 701. A drain pipe 703 is fixedly installed on one side of each of the two protective frames 702. A nozzle 704 is fixedly connected to one end of each of the two drain pipes 703. The opposite ends of the two drain pipes 703 are fixedly connected to the external body. The protective frames 702 can shield the milled area and prevent splashing, while the cooperation of the drain pipes 703 and nozzles 704 can drain external... The refrigerant is delivered to the milling area to cool the milled part of the shaft. The cooling assembly 7 also includes receiving grooves 705 opened at both ends along the length direction on the upper surface of the machining base 2. The inner walls of the two receiving grooves 705 are equipped with filters 706. The two ends along the length direction of the machining base 2 are equipped with return pipes 707 that communicate with the receiving grooves 705. The two return pipes 707 are connected to the external equipment for storing refrigerant. The receiving grooves 705 and return pipes 707 are used to recover the refrigerant after use and reuse it, while the filters 706 can filter the residue in the refrigerant.

[0042] The milling assembly 3 includes an electric push rod 301 fixedly mounted on the upper end of the processing base 2. A special-shaped frame 302 is fixedly mounted on the output end of the electric push rod 301. Both ends of the special-shaped frame 302 are rotatably connected to rotating rods 303. A set of milling saw blades 304 are fixedly connected to the circumference of both rotating rods 303. The two rotating rods 303 are connected to the processing base 2 via pulleys and belt drive. One of the rotating rods 303 is fixedly connected to the output end of an external motor. The two rotating rods 303 can rotate synchronously under the drive of the belt, so that the two milling saw blades 304 can perform milling work on both ends of the rotating shaft. The electric push rod 301 can control the height of the milling saw blades 304 by pushing the special-shaped frame 302.

[0043] The working principle of the above embodiment is as follows: When the rotating shaft is milled flat, the arranged rotating shaft is first placed into the feeding frame 9. The rotating shaft inside the feeding frame 9 will enter the feeding groove 8 under gravity and roll into the clamping groove 603 at the upper end of the bearing plate 5. Then, the two cylinders 14 simultaneously push the bearing plate 5 to be conveyed and raised in the sliding groove 4 and contact the clamping plate 602. At this time, the clamping plate 602 will slide in the sliding groove 601 and stretch the spring 604. When the rotating shaft passes through the two elastic rods 11, the two elastic rods 11 will contact the two ends of the rotating shaft respectively and push the rotating shaft so that the milling allowance at both ends of the rotating shaft is the same, ensuring that the milling length is consistent. When the clamping plate 602 slides to the limit in the sliding groove 601, the T-shaped bottom end of the clamping plate 602 will contact the inner top wall of the sliding groove 601, and through the thrust of the cylinder 14, the clamping plate 602 and the bearing plate 5 can tightly clamp the rotating shaft.

[0044] Subsequently, an external motor drives one of the rotating rods 303 to rotate, and through belt transmission, the two rotating rods 303 rotate synchronously, driving the milling saw blades 304 to rotate. Then, the electric push rod 301 pushes the irregular frame 302 down, so that multiple milling saw blades 304 contact the rotating shaft and perform milling work on the rotating shaft. During this process, the external pump can deliver refrigerant into the drain pipe 703 and spray it onto the rotating shaft through the nozzle 704, thereby cooling the milled part of the rotating shaft. The used refrigerant can pass through the filter screen 706 into the receiving tank 705 and return to the external refrigerant storage device through the return pipe 707. The residue in the refrigerant will be intercepted by the filter screen 706. At the same time, during the milling process, the protective frame 702 can protect the milled area and prevent the residue from splashing into the surrounding area.

[0045] After the shaft is milled flat, the cylinder 14 drives the bearing plate 5 to reset. Subsequently, the deformation force of the spring 604 drives the clamping plate 602 to reset, causing the bottom end of the clamping plate 602 to squeeze the air inside the sliding groove 601, and the air is discharged through the air inlet groove 605. This process takes a certain amount of time. When the bearing plate 5 slides in the sliding groove 4, the shaft will separate from the clamping plate 602. When the shaft passes the elastic rod 11, the elastic rod 11 can push the shaft out of the clamping groove 603 and roll it along the ramp 12 onto the bearing plate 13, thereby realizing automatic material unloading.
