Description

Technical Field

[0001] This utility model relates to the field of CNC technology, specifically to a rapid prototyping equipment for watch cases using CNC technology. Background Technology

[0002] Numerical control technology, also known as numerical control technology, is a technology that uses digital information to control mechanical motion and machining processes. It converts information such as the drawings, process parameters, and machining steps of the parts to be machined into digital codes, which are then input into the numerical control system. The numerical control system then automatically directs the machine tool or other equipment to perform machining according to a predetermined program, thereby achieving high-precision and high-efficiency automated production.

[0003] The CNC technology used in the production process of metal watch cases is different from the traditional process, which requires stamping to form the watch blank and then transferring it to the milling machine for contour processing. The process of producing metal watch cases involves multiple manual handling and equipment switching from roughing to fine machining, which makes it impossible to achieve rapid forming of metal watch cases and thus limits production efficiency. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a CNC-based rapid prototyping equipment for watch cases, which has advantages such as increasing the speed of watch case prototyping and solves the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a CNC rapid prototyping equipment for watch cases, comprising a machine body, wherein a transfer assembly is provided inside the machine body, the transfer assembly includes a swing frame located above the machine body, transfer frames are connected to both sides of the swing frame, a set of magnets are installed at the bottom of each of the two transfer frames, and a transfer groove with a size equivalent to the watch case being processed is opened on the upper surface of each of the two transfer frames, two bases are installed on the upper surface of the machine body, and a groove with a size equivalent to the transfer frame is opened on the upper surface of each of the two bases, wherein a stamping assembly, a milling assembly, and a drilling assembly are provided inside the machine body.

[0006] The above scheme enables collaborative operation between the left and right sides by setting up a transfer component. After the blank is stamped on the left side, it can be quickly transferred to the right side, so that the stamping and subsequent processing steps are seamlessly connected, reducing intermediate waiting time.

[0007] Furthermore, a hydraulic rod is installed inside the machine body, and the output end of the hydraulic rod is rotatably connected to the bottom end of the swing frame.

[0008] The above scheme allows the hydraulic rod to push the swing frame upward, enabling the two transfer frames to separate from the two bases. When the transfer frames separate from the bases, the magnets on the transfer frames can attract the metal case, allowing it to be located inside the transfer frames. This facilitates the removal of the stamped metal case or its transport to the milling assembly.

[0009] Furthermore, a motor is installed on the inner top wall of the machine body, and a rotating rod is fixedly connected to the output end of the motor. A limit block is fixedly connected to the bottom end of the rotating rod, and the limit block is slidably inserted into the swing frame.

[0010] By using the above scheme, the rotation rod and the limit block are coordinated to drive the swing frame to swing inside the machine body under the drive of the motor, so that the transfer frame can transfer the metal case in the transfer slot.

[0011] Furthermore, an electric push rod is installed inside the body, and an electromagnetic bearing is fixedly connected to the output end of the electric push rod. The electromagnetic bearing is located in the base on the right side.

[0012] The above scheme, by setting up an electric push rod and an electromagnetic carrier, can push the metal case out of the transfer groove, which facilitates the milling assembly to mill the metal case. At the same time, the attraction of the electromagnetic carrier can keep the metal surface in a stable state and prevent the metal case from swinging during the milling process.

[0013] Furthermore, the stamping assembly includes a stamping mechanism installed on the top wall of the machine body. Two exhaust pipes are installed on the top wall of the machine body. The upper ends of the two exhaust pipes are fixedly connected to the output end of an external air pump, and the bottom ends of the two exhaust pipes are fixedly connected to nozzles. Two maintenance doors are hinged to the left side of the machine body.

[0014] The above scheme enables the stamping mechanism to stamp the parts, forming a blank. By combining the exhaust pipe and the nozzle, airflow can be sprayed into the groove, facilitating cleaning and preventing impurities from remaining in the groove.

[0015] Furthermore, the milling assembly includes a milling mechanism installed on the top wall of the machine body. Two universal joints are installed on the top wall of the machine body. Both universal joints are fixedly connected to the output end of an external water pump. The two universal joints are located on both sides of the milling mechanism.

[0016] The above solution allows for the application of a universal joint to spray cutting fluid onto the milling area, preventing excessively high temperatures during the milling process from affecting the machining accuracy of the metal case.

[0017] Furthermore, the drilling assembly includes an electric push rod II, which is fixedly connected to the upper surface of the machine body, and the output end of the electric push rod II is fixedly connected to a drilling mechanism.

[0018] The above scheme enables the drilling mechanism to drill holes in the metal case after milling, allowing the metal case to be stamped. After milling and drilling, rapid forming can be achieved.

[0019] Furthermore, a return frame is installed on the upper surface of the base on the right side, and a return pipe is fixedly connected to the right side of the return frame.

[0020] The above scheme, which includes a return frame and a return pipe, facilitates the return of used cutting fluid and allows for its filtration and reuse.

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

[0022] This CNC-based rapid prototyping equipment for watch cases features a transfer assembly that enables coordinated operation on both sides. After the watch blank is stamped on the left side, it can be quickly transferred to the right side, seamlessly connecting the stamping process with subsequent processing steps. This reduces intermediate waiting time and significantly improves the watch case forming speed. The right side is equipped with a milling assembly and drilling function, allowing drilling to be performed directly after milling. This avoids multiple handling and clamping of the watch blank between different processes, improving processing efficiency and reducing the risk of damage to the watch blank due to multiple handling.

[0034] 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.

[0035] Please see Figure 1 , Figure 2 and Figure 3 This embodiment of a CNC rapid prototyping equipment for watch cases includes a machine body 1. A transfer assembly 2 is disposed inside the machine body 1. The transfer assembly 2 includes a swing frame 201 located above the machine body 1. Transfer frames 202 are connected to both sides of the swing frame 201. A set of magnets 203 is installed at the bottom of each of the two transfer frames 202. A transfer groove 204 of the same size as the watch case being processed is formed on the upper surface of each of the two transfer frames 202. Two bases 205 are mounted on the upper surface of the machine body 1. A recess of the same size as the transfer frame 202 is formed on the upper surface of each of the two bases 205. The slot 206 and the interior of the machine body 1 are equipped with a stamping assembly 3, a milling assembly 4 and a drilling assembly 5. A transfer assembly 2 is set up to enable coordinated operation on the left and right sides. After the stamping of the watch blank is completed on the left side, the watch blank can be quickly transferred to the right side, so that the stamping and subsequent processing steps are seamlessly connected, reducing intermediate waiting time and greatly improving the forming speed of the watch case. The right side is equipped with a milling assembly 4 and a drilling function. After the milling is formed, drilling can be performed directly, avoiding multiple handling and clamping of the watch blank between different processes. This not only improves processing efficiency, but also reduces the risk of damage to the watch blank that may be caused by multiple handling.

[0036] Please see Figure 1 , Figure 2 and Figure 3The machine body 1 is equipped with a hydraulic rod 6. The output end of the hydraulic rod 6 is rotatably connected to the bottom end of the swing frame 201. The hydraulic rod 6 is configured to push the swing frame 201 upward, so that the two transfer frames 202 can separate from the two bases 205. When the transfer frame 202 separates from the base 205, the magnet 203 on the transfer frame 202 can attract the metal case, so that it can be located inside the transfer frame 202, making it easy to take out the stamped metal case or transport it to the milling assembly 4. The inner top wall of the machine body 1 is equipped with a motor 7. The output end of the motor 7 is fixedly connected to a rotating rod 8. The bottom end of the rotating rod 8 is fixedly connected to a limit block 9. The limit block 9 is slidably inserted into the swing frame 201. The cooperation between the rotating rod 8 and the limit block 9 can drive the swing frame 201 to swing inside the machine body 1 under the drive of the motor 7, so that the transfer frame 202 can transfer the metal case in the transfer groove 204.

[0037] Please see Figure 1 , Figure 2 and Figure 4 An electric push rod 10 is installed inside the body 1. An electromagnetic support 11 is fixedly connected to the output end of the electric push rod 10. The electromagnetic support 11 is located inside the base 205 on the right side. By cooperating with the electric push rod 10 and the electromagnetic support 11, the metal watch case can be pushed out of the transfer groove 204, facilitating milling by the milling assembly 4. Simultaneously, the attraction of the electromagnetic support 11 keeps the metal surface stable, preventing the metal watch case from swaying during milling. The stamping assembly 3 includes components installed on the top wall inside the body 1. The stamping mechanism 301 has two exhaust pipes 302 installed on the inner top wall of the machine body 1. The upper ends of the two exhaust pipes 302 are fixedly connected to the output end of an external air pump, and the lower ends of the two exhaust pipes 302 are fixedly connected to nozzles 303. Two maintenance doors 304 are hinged to the left side of the machine body 1. The stamping mechanism 301 can stamp the parts to form a blank. By setting the exhaust pipes 302 and nozzles 303, airflow can be sprayed into the groove 206, which facilitates cleaning of the groove 206 and avoids the retention of impurities in the groove 206.

[0038] Please see Figure 1 , Figure 2 and Figure 4The milling assembly 4 includes a milling mechanism 401 installed on the inner top wall of the machine body 1. Two universal joints 402 are installed on the inner top wall of the machine body 1, both of which are fixedly connected to the output end of an external water pump. The two universal joints 402 are located on both sides of the milling mechanism 401. The universal joints 402 allow for the spraying of cutting fluid onto the milling area, preventing excessively high temperatures during milling that could affect the machining accuracy of the metal casing. The drilling assembly 5 includes a second electric push rod 501, which is fixedly attached to the upper surface of the machine body 1. The output end of the electric push rod 501 is fixedly connected to a drilling mechanism 502. The drilling mechanism 502 can drill holes in the metal case after milling, so that the metal case can be stamped. After milling and drilling, rapid forming can be achieved. A return frame 12 is installed on the upper surface of the base 205 on the right side. A return pipe 13 is fixedly connected to the right side of the return frame 12. The return frame 12 and the return pipe 13 can facilitate the return of the used cutting fluid, and facilitate the filtration and reuse of the cutting fluid.

[0039] This embodiment of a CNC-based rapid prototyping equipment for watch cases includes a transfer component 2 that enables coordinated operation on both sides. After the watch blank is stamped on the left side, it can be quickly transferred to the right side, allowing for seamless connection between stamping and subsequent processing steps. This reduces intermediate waiting time and greatly improves the watch case forming speed. The right side is equipped with a milling component 4 and a drilling function, which allows for direct drilling after milling. This avoids multiple handling and clamping of the watch blank between different processes, improving processing efficiency and reducing the risk of damage to the watch blank due to multiple handling.

[0040] It should be noted that the internal space of the body 1 does not affect the normal swing of the swing frame 201 and the transfer frame 202;

[0041] The electromagnetic carrier 11 consists of a coil, an iron core, and a shell. When current passes through the coil, a magnetic field is generated around the iron core, which magnetizes the iron core and attracts or repels other magnetic objects.

[0042] The working principle of the above embodiment is as follows: When the watch case is being formed, the part is placed into the groove 206 of the left base 205 through the inspection port on the left side of the machine body 1. Then, the stamping mechanism 301 can stamp the part in the groove 206. After the stamping is completed, the external air pump can deliver compressed gas to the two exhaust pipes 302 and spray it into the groove 206 from the two nozzles 303 to avoid impurities remaining in the groove 206. Then, the hydraulic rod 6 pushes the swing frame 201 to rise, so that the transfer frame 202 can move away from the groove 206. The magnet 203 on the transfer frame 202 can attract the stamped watch blank, so that it can be separated from the groove 206 on the left. Then, the motor 7 starts and drives the swing frame 201 to rotate through the rotating rod 8 and the limiting member, so that the swing frame 201 on the left can be located in the groove 206 on the right. Then, the electromagnetic bearing 11 is energized and generates magnetic force to attract the metal watch case. The electric push rod 10 starts and pushes the electromagnetic bearing. The carrier 11 pushes the watch blank out of the transfer groove 204. At this time, the milling mechanism 401 can perform milling on the watch blank. During the milling process, the external water pump can deliver cutting fluid to the two universal pipes 402 and spray it onto the milling area to facilitate the milling work. The used cutting fluid can be recycled through the return frame 12 and the return pipe 13 for reuse. After the milling is completed, the electric push rod 501 can push the drilling mechanism 502 to directly drill holes on the edge of the metal watch case, avoiding multiple handling and clamping of the watch blank between different processes. This not only improves the processing efficiency but also reduces the risk of damage to the watch blank caused by multiple handling. Since the milling speed is relatively slow while the stamping speed is relatively fast, the operator can repeatedly perform stamping work at the maintenance point of the machine body 1 during operation. The lifting of the transfer frame 202 makes it easy for the operator to remove the material. After the milling is completed, the operator removes the formed watch case, and the machine body 1 performs rapid forming of the watch case again.
