Description

Technical Field

[0001] This utility model relates to a milling cutter, specifically a coated milling cutter with a rapid heat dissipation structure, belonging to the field of milling cutter technology. Background Technology

[0002] In the field of machining, the annular groove is a key structure for many parts. Its machining accuracy and efficiency directly determine the assembly performance and service life of the parts. At present, the industry generally adopts the machining mode of "fixed tool - high-speed workpiece rotation" for the machining of annular grooves. This mode involves the workpiece moving in a high-speed circular motion around a fixed milling cutter, so that the milling cutter edge continuously contacts and cuts the workpiece surface to be machined, thereby forming an annular groove that meets the size requirements.

[0003] However, this traditional processing method often has various problems in practical applications. For example, in a milling cutter with a heat dissipation structure disclosed in publication number CN221538216U, although the circulating water pump can transfer condensate to the inside of the circulating water pipe through the cooperation between the circulating water pump, circulating water pipe and cooling pipe, and the condensate circulates inside the milling cutter body through the circulating water pipe to facilitate the cooling of the milling cutter body, in this technical solution and most current milling cutter operations, when the workpiece rotates at high speed around the fixed milling cutter, the cutting area of ​​the milling cutter and the workpiece will form a relatively closed local space. On the one hand, the high-speed rotation of the workpiece will drive the surrounding air to form a following circulation, and this circulation will cause the milling cutter to be affected by the high-speed rotation of the workpiece. An "airflow stagnation zone" forms near the cutting tool, making it difficult for fresh, cool air to enter the cutting area and exchange heat with the cutter surface. On the other hand, the cutter itself is in a fixed state and cannot break the static balance of the surrounding air through its own movement, further exacerbating the problem of obstructed airflow. At the same time, during the cutting process, the intense friction between the cutter and the workpiece material generates a large amount of cutting heat. Due to the aforementioned problem of poor airflow, the heat generated by the cutter cannot be quickly dissipated through convection heat transfer, causing the cutter temperature to rise rapidly in a short period of time. Therefore, developing a coated cutter that can break the air stagnation in the cutting area and achieve rapid heat dissipation has become a technical problem that urgently needs to be solved in the current machining field. Utility Model Content

[0004] This utility model provides a solution that is significantly different from existing technologies, addressing the problem that existing technologies are too simplistic. Specifically, the purpose of this utility model is to solve the aforementioned shortcomings of existing technologies by proposing a coated milling cutter with a rapid heat dissipation structure.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A coated milling cutter with a rapid heat dissipation structure includes a support base, a drive rod, a revolution milling assembly, and a rotation assembly. The drive rod is rotatably connected to the support base, and the revolution milling assembly is connected to one end of the drive rod. The assembly includes a docking plate, a first transmission rod, a support base, a mounting cylinder, and a milling cutter body. The center of the docking plate is fixed to one end of the drive rod, and two first transmission rods are rotatably connected to both ends of the docking plate. The center of one side of the support base is fixed to one end of the first transmission rod, and the mounting cylinder is fixed to the center of the other side of the support base. The milling cutter body is disposed inside the mounting cylinder. The self-rotating component is mounted on the support base and includes a linkage cylinder, a linkage gear, and a driven gear. The linkage cylinder is coaxially rotatably sleeved outside the driving rod and rotatably connected to the support base. The linkage gear is coaxially fixed to one end of the linkage cylinder and rotatably connected to the driving rod. The driven gear is coaxially fixed to the other end of the first transmission rod and meshes with the linkage gear.

[0006] As a further embodiment of this utility model: the self-rotating assembly further includes a driven gear and a transmission gear. The driven gear is coaxially fixed to the other end of the linkage cylinder and rotatably connected to the driving rod. The transmission gear is rotatably connected to the support base and meshes with the driven gear on one side.

[0007] As a further embodiment of this utility model: the self-rotating component also includes a docking gear and a driving gear. The docking gear is coaxially fixed to one end of the transmission gear, and the driving gear is coaxially fixed to the driving rod and meshes with the docking gear.

[0008] As a further improvement of this utility model: both the linkage gear and the driven gear are helical gear structures, and the diameter of the linkage gear is larger than that of the driven gear.

[0009] As a further improvement of this invention, the surface of the milling cutter body is provided with a diamond coating.

[0010] As a further improvement of this utility model: multiple screws are provided on the side wall of the mounting cylinder, the multiple screws are equidistantly distributed and all abut against the milling cutter body, and the milling cutter body is detachably connected to the mounting cylinder by the screws.

[0011] The beneficial effects of this utility model are: In the revolution milling assembly of this utility model, the driving rod drives the docking plate, the first transmission rod, the support seat, the mounting cylinder, and the milling cutter body to revolve. At the same time, the rotation assembly, through the cooperation of components such as the linkage cylinder, the linkage gear, and the driven gear, causes the first transmission rod to drive the milling cutter body to rotate. The revolution and rotation of the milling cutter body breaks the static balance of the surrounding air when the traditional tool is fixed, promotes air circulation in the cutting area, effectively avoids the formation of "airflow stagnation zone", and accelerates heat dissipation. Moreover, the linkage gear and the driven gear in the rotation assembly mesh with each other, and the driven gear, transmission gear, docking gear, and driving gear cooperate to ensure the accuracy and stability of the revolution and rotation of the milling cutter body, providing a reliable guarantee for efficient and high-precision machining. At the same time, the stable motion state helps to continuously dissipate heat and avoids the heat dissipation effect being affected by motion vibration. Attached Figure Description

[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model. Example 1

[0015] like Figures 1 to 4As shown, a coated milling cutter with a rapid heat dissipation structure includes a support base 1, a drive rod 2, a revolution milling assembly, and a rotation assembly 8. The drive rod 2 is rotatably connected to the support base 1, and the revolution milling assembly is connected to one end of the drive rod 2. It includes a docking plate 3, a first transmission rod 4, a support base 5, a mounting cylinder 6, and a milling cutter body 7. The center of the docking plate 3 is fixed to one end of the drive rod 2. The two first transmission rods 4 are rotatably connected to the two ends of the docking plate 3, respectively. The center of one side of the support base 5 is fixed to one end of the first transmission rod 4. The mounting cylinder 6 is fixed to the center of the other side of the support base 5. The milling cutter body 7 is disposed inside the mounting cylinder 6. The self-rotating component 8 is mounted on the support base 1 and includes a linkage cylinder 81, a linkage gear 82, and a driven gear 83. The linkage cylinder 81 is coaxially rotatably sleeved on the outside of the driving rod 2 and rotatably connected to the support base 1. The linkage gear 82 is coaxially fixed to one end of the linkage cylinder 81 and rotatably connected to the driving rod 2. The driven gear 83 is coaxially fixed to the other end of the first transmission rod 4 and meshes with the linkage gear 82. The self-rotating assembly 8 also includes a driven gear 84 and a transmission gear 85. The driven gear 84 is coaxially fixed to the other end of the linkage cylinder 81 and is rotatably connected to the driving rod 2. The transmission gear 85 is rotatably connected to the support base 1 and meshes with one side of the driven gear 84. The self-rotating assembly 8 also includes a docking gear 86 and a driving gear 87. The docking gear 86 is coaxially fixed to one end of the transmission gear 85, and the driving gear 87 is coaxially fixed to the driving rod 2 and meshes with the docking gear 86.

[0016] In the revolution milling assembly of this utility model, the driving rod 2 drives the docking plate 3, the first transmission rod 4, the support seat 5, the mounting cylinder 6, and the milling cutter body 7 to revolve. At the same time, the rotation assembly 8, through the cooperation of components such as the linkage cylinder 81, the linkage gear 82, and the driven gear 83, causes the first transmission rod 4 to drive the milling cutter body 7 to rotate. The revolution and rotation of the milling cutter body 7 breaks the static balance of the surrounding air when the traditional tool is fixed, promotes air circulation in the cutting area, effectively avoids the formation of "airflow stagnation zone", and accelerates heat dissipation. Moreover, the linkage gear 82 and the driven gear 83 in the rotation assembly 8 mesh with each other, and the driven gear 84, the transmission gear 85, the docking gear 86, and the driving gear 87 cooperate to ensure the accuracy and stability of the revolution and rotation of the milling cutter body 7, providing a reliable guarantee for efficient and high-precision machining. At the same time, the stable motion state helps to continuously dissipate heat and avoids the heat dissipation effect being affected by motion vibration. Example 2

[0017] like Figures 1 to 4 As shown, in addition to all the technical features included in Embodiment 1, this embodiment also includes: Both the linkage gear 82 and the driven gear 83 are helical gears, and the diameter of the linkage gear 82 is larger than that of the driven gear 83. Compared with spur gear transmission, the helical gear structure has a longer tooth surface meshing line, resulting in less impact and vibration during transmission. This can significantly reduce gear meshing noise, improve the stability of the transmission system, avoid milling cutter trajectory deviation caused by transmission vibration, and ensure the dimensional accuracy of the annular groove machining.

[0018] The surface of the milling cutter body 7 is coated with a diamond coating to maintain the sharpness of the cutting edge, avoid the problem of increased cutting resistance and sudden heat rise caused by the dulling of the cutting edge, ensure stable cutting force during machining, and improve the surface finish of the annular groove.

[0019] Multiple screws are provided on the side wall of the mounting cylinder 6. The screws are evenly distributed and all abut against the milling cutter body 7. The milling cutter body 7 is detachably connected to the mounting cylinder 6 by screws. When the milling cutter body 7 is worn or a different type of tool needs to be replaced, it is not necessary to disassemble the entire revolution milling assembly. The tool can be replaced simply by loosening the screws, which greatly shortens the downtime for maintenance and improves production efficiency.

[0020] Working principle: When using this milling cutter, the drive rod 2 is first connected to an external power source to prepare to drive the entire system. Under the action of the power source, the drive rod 2 begins to rotate, and the docking plate 3 fixed at one end rotates synchronously, thereby driving the two first transmission rods 4 to revolve around the drive rod 2 in a circle. This causes the support 5, mounting cylinder 6, and milling cutter body 7 to form a revolving milling assembly, completing the basic trajectory movement for machining the annular groove. When the drive rod 2 rotates, the coaxially fixed drive gear 87 rotates synchronously and meshes with the docking gear 86 for transmission. The transmission gear 85 is driven to rotate; the transmission gear 85 then meshes with the driven gear 84, driving the driven gear 84, which is coaxially fixed on the linkage cylinder 81, to rotate. This causes the linkage cylinder 81, which is coaxially sleeved outside the driving rod 2, to rotate. When the linkage cylinder 81 rotates, the linkage gear 82, which is coaxially fixed at one end, rotates accordingly and meshes with the driven gear 83 for transmission. The driven gear 83 is coaxially fixed at the other end of the first transmission rod 4, thereby driving the first transmission rod 4 to rotate. This allows the mounting cylinder 6 and the milling cutter body 7 to complete their rotational motion while revolving around the central axis.
