Description

Technical Field

[0001] This utility model relates to the field of watch case processing technology, specifically a CNC machining device for high-gloss chamfering of watch case surfaces. Background Technology

[0002] Watch case machining refers to the process of precision machining of the outer shell (usually made of metal, ceramic or composite materials) of products such as watches and smart wearable devices. It includes processes such as cutting, milling, drilling, chamfering and polishing to achieve the dimensional accuracy, surface finish and assembly compatibility required by the design.

[0003] An existing patent (publication number: CN220783447U) discloses a watch case polishing machine, relating to the field of watch case polishing technology. This watch case polishing machine includes a base plate with two fixing plates mounted on its surface. A first connecting plate is fixedly mounted on the side of the base plate, allowing the operator to place the watch case on the surface of a second pad. Turning a knob causes a lead screw to rotate, pushing one of the fixing plates to secure the watch case. This manual fixing by the operator ensures a more stable and damage-free fixation. Activating a first motor drives a second gear, which in turn moves the first and third gears along with a rack. Activating the second motor then drives a polishing pad to polish the watch case, allowing for comprehensive polishing of the watch case, resulting in a larger and more thorough polishing area and saving labor.

[0004] The polishing machine described above allows the polishing pads to polish the watch case from all angles, resulting in a larger and more thorough polishing area and saving labor. However, because the fixing plate slides on the base plate, the polishing process can only be carried out on the front and back sides of the watch case sequentially. This process requires fixing the watch case multiple times, making the whole process quite cumbersome. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a CNC machining device for high-gloss chamfering of watch case surfaces, which has advantages such as flexible clamping and double-sided chamfering of watch cases, thus solving the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a CNC machining device for high-gloss chamfering of watch case surface, comprising a base, two frames arranged above the base, arc-shaped clamping plates arranged inside the two frames, a watch case body arranged between the two arc-shaped clamping plates, annular tubes installed on the inner walls of the right frame, spray holes opened on the inner walls of the annular tubes, and the annular tubes are fixedly connected to the output end of an external air pump.

[0007] The above solution combines the advantages of flexible clamping and rigid fixing by using an arc-shaped clamping plate design with a left rubber and a right magnet. The left rubber clamping plate can adapt to different sizes of watch cases due to its elastic deformation capability, thus avoiding surface scratches.

[0008] Furthermore, the arc-shaped clamping plate on the right side is rotatably connected to the frame adjacent to it, and a motor is installed inside the frame on the left side. The output end of the motor is fixedly connected to a rotating rod, which passes through the frame and is fixedly connected to the arc-shaped clamping plate on the left side.

[0009] With the above solution, the right arc-shaped clamping plate is rotatably connected to the frame, which facilitates the simultaneous flipping of the watch case body with the left arc-shaped clamping plate. By flipping the watch case body, it is convenient to perform chamfering work on the other side of the watch case body.

[0010] Furthermore, a support frame is fixedly connected to the upper surface of the base, the left frame is slidably connected to the inner wall of the support frame, and the right frame is fixed to the support frame.

[0011] The above solution allows the support frame to limit the left frame, enabling it to slide stably. After contacting the right frame, it forms a conical hopper for collecting impurities, facilitating the collection of impurities generated during chamfering.

[0012] Furthermore, a cylinder is installed on the inner wall of the support frame, and the output end of the cylinder is fixedly connected to the left frame.

[0013] The above scheme allows the cylinder to push multiple frames to slide to the right. After the left frame contacts the right frame, they form a whole for collecting impurities, which facilitates the unified processing of impurities.

[0014] Furthermore, the bottom end of the frame on the right is fixedly connected to an extraction tube, the right end of the extraction tube is threadedly connected to a collection frame, the inner wall of the collection frame is fitted with a filter screen, and the right end of the collection frame is fixedly connected to a connecting pipe, which is fixedly connected to the output end of an external extraction device.

[0015] The above solution allows the filter to intercept impurities, facilitating subsequent disassembly and processing of the impurities within the collection box.

[0016] Furthermore, a fixing frame is fixedly connected to the upper surface of the base, an electric push rod is installed on the inner top wall of the fixing frame, and a chamfering mechanism is installed at the output end of the electric push rod.

[0017] By using the above scheme, the electric push rod and the chamfering mechanism are coordinated to adjust the position of the chamfering mechanism, enabling it to perform chamfering work on the watch case body.

[0018] Furthermore, the two frames are combined in a cone shape.

[0019] The above scheme allows the two frames to be combined to form a conical frame for impurity collection, enabling impurities to be collected through an extraction tube after entering the frame.

[0020] Compared with the prior art, the technical solution of this utility model has the following beneficial effects:

[0021] This CNC machining device for high-gloss chamfering of watch case surfaces combines the advantages of flexible clamping and rigid fixation through an arc-shaped clamping plate design with a left rubber gripper and a right magnet. The left rubber gripper, with its elastic deformation capability, can adapt to watch cases of different sizes, avoiding surface scratches while providing stable anti-slip clamping. The right magnet gripper uses a magnetic field to achieve rapid positioning and firm fixation, ensuring stability during processing. This method not only improves clamping accuracy, but the left arc-shaped clamping plate can also smoothly flip the watch case after the initial processing, facilitating efficient double-sided chamfering. In addition, the airflow through the nozzles at the top of the frame forms a closed air curtain, effectively blocking the splashing of processing debris, keeping the working environment clean, and optimizing the clamping efficiency, processing accuracy, and safety of metal watch case processing. It is suitable for the automated production needs of high-precision watch cases. Attached Figure Description

[0028] 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.

[0029] Please see Figure 2 , Figure 3 and Figure 4 This embodiment describes a CNC machining device for high-gloss chamfering of a watch case surface. It includes a base 1 with two frames 2 on top. Each frame 2 has an arc-shaped clamping plate 3 inside. The left arc-shaped clamping plate 3 is made of rubber, while the right arc-shaped clamping plate 3 is made of magnet. A watch case body 4 is positioned between the two arc-shaped clamping plates 3. Annular tubes 5 are installed on the inner walls of the right frame 2, and each annular tube 5 has spray holes 6 on its inner wall. The annular tubes 5 are fixedly connected to the output end of an external air pump. By employing the arc-shaped clamping plate 3 with rubber on the left and magnet on the right, the advantages of flexible clamping and rigid fixation are combined. The left rubber clamping plate... With its elastic deformation capability, it can adapt to watch cases of different sizes, avoid surface scratches, and provide stable anti-slip clamping. The magnetic clamping plate on the right side uses magnetic field to achieve rapid positioning and firm fixation, ensuring stability during processing. This method not only improves clamping accuracy, but the arc-shaped clamping plate 3 on the left side can also achieve smooth flipping of the watch case after the initial processing, which is convenient for efficient double-sided chamfering. In addition, the airflow formed by the nozzle 6 at the upper end of the frame 2 forms a closed air curtain, which effectively blocks the splashing of processing debris, keeps the working environment clean, and optimizes the clamping efficiency, processing accuracy and safety of metal watch case processing, making it suitable for the automated production needs of high-precision watch cases.

[0030] Please see Figure 1 , Figure 2 and Figure 3 The right-side arc-shaped clamping plate 3 is rotatably connected to the adjacent frame 2. The left-side frame 2 has a motor 7 installed inside, and the output end of the motor 7 is fixedly connected to a rotating rod 8. The rotating rod 8 passes through the frame 2 and is fixedly connected to the left-side arc-shaped clamping plate 3. The right-side arc-shaped clamping plate 3 is rotatably connected to the frame 2, which facilitates the simultaneous flipping of the watch case body 4 with the left-side arc-shaped clamping plate 3. By flipping the watch case body 4, it is convenient to perform chamfering work on the other side of the watch case body 4. The upper surface of the base 1 is fixedly connected to a support frame 9. The left-side frame 2 is slidably connected to the inner wall of the support frame 9. The right-side frame 2 is fixed on the support frame 9. The support frame 9 can limit the left-side frame 2, so that the left-side frame 2 can maintain stable sliding. After contacting the right-side frame 2, it can form a conical hopper for collecting impurities, which is convenient for collecting impurities generated during chamfering.

[0031] Please see Figure 1 , Figure 2 and Figure 3 A cylinder 10 is installed on the inner wall of the support frame 9. The output end of the cylinder 10 is fixedly connected to the left frame 2. The cylinder 10 can push multiple frames 2 to slide to the right. After the left frame 2 and the right frame 2 come into contact, they form a whole for collecting impurities, which facilitates the unified recycling and processing of impurities. The bottom end of the right frame 2 is fixedly connected to an extraction pipe 11. The right end of the extraction pipe 11 is threadedly connected to a collection frame 12. A filter screen 13 is installed on the inner wall of the collection frame 12. The right end of the collection frame 12 is fixedly connected to a connecting pipe 14. The connecting pipe 14 is fixedly connected to the output end of an external extraction device. The filter screen 13 can intercept impurities, which facilitates the subsequent disassembly of the collection frame and the processing of impurities in the collection frame 12.

[0032] Please see Figure 1 , Figure 2 and Figure 3 A fixed frame 15 is fixedly connected to the upper surface of the base 1. An electric push rod 16 is installed on the inner top wall of the fixed frame 15. A chamfering mechanism 17 is installed at the output end of the electric push rod 16. The cooperation between the electric push rod 16 and the chamfering mechanism 17 enables the adjustment of the position of the chamfering mechanism 17, so that it can perform chamfering work on the watch case body 4. The two frames 2 are combined into a cone shape. The combination of the two frames 2 can form a cone-shaped frame for collecting impurities, so that impurities can be collected through the extraction tube 11 after entering the frame 2.

[0033] The working principle of the above embodiment is as follows: When performing chamfering on the watch case body 4, the watch case body 4 is first placed inside the right frame 2 and comes into contact with the right arc-shaped clamping plate 3, causing the arc-shaped clamping plate 3 to adsorb the watch case body 4. At this time, the watch case body 4 is adsorbed onto the right arc-shaped clamping plate 3. Subsequently, the cylinder 10 pushes the left frame 2 to slide on the support frame and come into contact with the right frame 2. When the two frames 2 come into contact, a complete frame can be formed. Then, the electric push rod 16 pushes the chamfering mechanism 17 to descend, so that the chamfering mechanism 17 performs chamfering on the watch case body 4. During this process, an external air pump delivers gas into the annular pipe 5 and sprays it from multiple nozzles. 6. The air is sprayed out, forming an air curtain above the two frames 2. This prevents impurities from splashing during the chamfering of the watch case body 4. The air curtain can intercept the impurities inside the frames 2. At this time, the external extraction device will transfer the suction force through the collection frame 12 to the extraction tube 11. The impurities inside the frames 2 will enter the collection frame 12 and be intercepted by the filter screen 13. After the chamfering of the upper surface of the watch case body 4 is completed, the motor 7 starts and drives the left arc-shaped clamping plate 3 to rotate through the rotating rod 8. Since the right arc-shaped clamping plate 3 is rotatably connected to the right frame 2, the two arc-shaped frames 2 can rotate synchronously and flip the watch case body 4, which is convenient for chamfering the other side of the watch case body 4.
