[0003]然而现有的铣刀大多存在着各种问题,例如在公告号CN218396135U所公开的一种具有自润滑功能的高效涂层铣刀中,其虽然通过三组联动板同步联动使连接杆被快速锁定并实现对中,但是在该技术方案以及目前大多数的涂层铣刀中,为满足不同加工需求,加工过程中需通过移动组件调节涂层铣刀的空间位置,目前,行业内主流的铣刀位置调节方案多以螺纹杆为核心传动部件,通过旋转螺纹杆带动铣刀或其安装座实现位移,由于螺纹杆传动需同步控制其旋转精度与轴向定位,且部分大型加工场景中螺纹杆及配套结构自重较大,单名操作人员难以同时完成旋转调节、位置校准及稳定性把控,导致调节作业必须至少两人协同进行——一人负责旋转螺纹杆,另一人负责观测铣刀位置、辅助固定或调整校准基准,这种多人协同的调节模式,不仅增加了人力成本投入,还易因人员操作节奏不一致、观测误差等因素延长调节耗时,降低加工效率;同时,多人配合过程中的操作协同问题,也可能对铣刀调节精度造成干扰,间接影响工件加工质量,难以适配当前机械加工领域对高效、低成本、高精度作业的发展需求

Abstract
Description
Technical Field
[0001] This utility model relates to a milling cutter, specifically a high-temperature resistant and antioxidant coated milling cutter, belonging to the field of milling cutter technology. Background Technology
[0002] In the field of machining, coated end mills have become an indispensable key tool in the milling of metal and other workpieces due to their superior performance advantages. These tools are coated with a specific material to form a coating on the surface of the cutter body, which significantly improves their wear resistance and cutting performance. For this reason, coated end mills are widely used in industries with extremely high requirements for workpiece machining accuracy and surface quality, such as aerospace, automobile manufacturing, and mold processing, and play a vital role in the milling of metal and other workpieces.
[0003] However, most existing milling cutters have various problems. For example, in a high-efficiency coated milling cutter with self-lubricating function disclosed in announcement number CN218396135U, although the connecting rod is quickly locked and centered through the synchronous linkage of three sets of linkage plates, in this technical solution and most current coated milling cutters, in order to meet different processing requirements, the spatial position of the coated milling cutter needs to be adjusted by moving components during the processing. Currently, the mainstream milling cutter position adjustment schemes in the industry mostly use a threaded rod as the core transmission component, and the displacement is achieved by rotating the threaded rod to drive the milling cutter or its mounting base. Since the threaded rod transmission needs to synchronously control its rotational accuracy and axial positioning, and in some large-scale processing scenarios... The threaded rod and its associated structure are quite heavy, making it difficult for a single operator to simultaneously complete rotation adjustment, position calibration, and stability control. This necessitates at least two people working together for the adjustment operation—one person rotates the threaded rod, while the other observes the milling cutter position and assists in fixing or adjusting the calibration reference. This multi-person collaborative adjustment mode not only increases labor costs but also easily prolongs adjustment time and reduces processing efficiency due to inconsistent operating rhythms and observation errors. Furthermore, the operational coordination issues during multi-person cooperation may also interfere with the milling cutter adjustment accuracy, indirectly affecting the workpiece machining quality. This approach is ill-suited to the current development needs of the machining industry for efficient, low-cost, and high-precision operations. 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 high-temperature resistant and antioxidant coated milling cutter.
[0005] To achieve the above objectives, the present invention adopts the following technical solution: A high-temperature resistant and antioxidant coating end mill includes a base, a guide rod, a linkage seat, a support rod, a coating end mill, and a displacement mechanism. The guide rod is fixed on the base, the linkage seat is slidably connected to the guide rod, the support rod is fixed on the linkage seat, the coating end mill is fixed to one end of the support rod, and a handle is fixed to the other end of the support rod. The displacement mechanism is disposed on the linkage seat. The displacement mechanism includes a limiting cylinder, a positioning rod, a limiting slot, and a linkage unit. The limiting cylinder is coaxially slidably connected to the outside of the guide rod, and one end of the limiting cylinder is rotatably connected to the linkage seat. The limiting cylinder has a through hole that extends radially through it, and the positioning rod is slidably engaged in the through hole. The limiting slot is set on the peripheral wall and has a spiral structure, and one end of the positioning rod is slidably engaged in the limiting slot.
[0006] As a further embodiment of this utility model: the linkage unit includes a ratchet and a pawl. The ratchet is coaxially fixed outside the limiting cylinder, and one end of the pawl is rotatably connected to the linkage seat, while the other end slides against the peripheral wall of the ratchet.
[0007] As a further improvement of this utility model: a leaf spring is fixed on the linkage seat, and the leaf spring part slides and abuts against the pawl.
[0008] As a further improvement of this utility model: a return spring is sleeved on the outside of the positioning rod, one end of the return spring is fixed to the top of the positioning rod, and the other end is fixed to the limiting cylinder.
[0009] As a further improvement of this utility model, the coated milling cutter is provided with a high-temperature resistant and antioxidant coating on its exterior.
[0010] As a further improvement of this utility model, the guide rod is provided in various models, and the length of each model is different. The guide rod is detachably connected to the base by screws.
[0011] The beneficial effects of this utility model are: In this invention, the limiting cylinder in the displacement mechanism is coaxially and slidably connected to the outside of the guide rod, ensuring that the linkage seat slides stably along the guide rod during adjustment. The positioning rod is slidably engaged in the through hole of the limiting cylinder and the spiral limiting groove of the guide rod. When the limiting cylinder is rotated, the adjusted position can be locked by the cooperation of the ratchet and the pawl, and the precise displacement is achieved by the cooperation of the positioning rod and the limiting groove, avoiding adjustment deviation. The handle at the end of the support rod cooperates with the displacement mechanism, allowing the operator to complete the milling cutter position adjustment by one person—without the need for multiple people to work together, solving the problem that traditional thread rod adjustment requires at least two people to operate, reducing manpower input while improving operating efficiency.

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.

[0015] like Figures 1 to 4 As shown, a high-temperature resistant and anti-oxidation coated milling cutter includes a base 1, a guide rod 2, a linkage seat 3, a support rod 4, a coated milling cutter 5, and a displacement mechanism 6. The guide rod 2 is fixed on the base 1, the linkage seat 3 is slidably connected to the guide rod 2, the support rod 4 is fixed on the linkage seat 3, the coated milling cutter 5 is fixed to one end of the support rod 4, and a handle 7 is fixed to the other end of the support rod 4. The displacement mechanism 6 is set on the linkage seat 3. The displacement mechanism 6 includes a limiting cylinder 61, a positioning rod 62, a limiting slot 63, and a linkage unit. The limiting cylinder 61 is coaxially slidably connected to the outside of the guide rod 2, and one end of the limiting cylinder 61 is rotatably connected to the linkage seat 3. The limiting cylinder 61 has a through hole that runs through it radially. The positioning rod 62 is slidably engaged in the through hole. The limiting slot 63 is set on the peripheral wall and has a spiral structure. One end of the positioning rod 62 is slidably engaged in the limiting slot 63. The linkage unit includes a ratchet 64 and a pawl 65. The ratchet 64 is coaxially fixed to the outside of the limiting cylinder 61. One end of the pawl 65 is rotatably connected to the linkage seat 3, and the other end slides against the peripheral wall of the ratchet 64. A leaf spring 66 is fixed on the linkage seat 3. The leaf spring 66 slides and abuts against the pawl 65. A return spring 67 is sleeved on the outside of the positioning rod 62. One end of the return spring 67 is fixed to the top of the positioning rod 62, and the other end is fixed to the limiting cylinder 61.
[0016] In this invention, the limiting cylinder 61 in the displacement mechanism 6 is coaxially and slidably connected to the outside of the guide rod 2, ensuring that the linkage seat 3 slides stably along the guide rod 2 during the adjustment process; the positioning rod 62 is slidably engaged in the through hole of the limiting cylinder 61 and the spiral limiting groove 63 of the guide rod 2. When the limiting cylinder 61 is rotated, the adjusted position can be locked by the cooperation of the ratchet 64 and the pawl 65, and the precise displacement can be achieved by the cooperation of the positioning rod 62 and the limiting groove 63, avoiding adjustment deviation; the handle 7 at the end of the support rod 4 cooperates with the displacement mechanism 6, allowing the operator to complete the milling cutter position adjustment by one person - without the need for multiple people to cooperate, solving the problem that traditional thread rod adjustment requires at least two people to work, reducing manpower input while improving operating efficiency. 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: The coated end mill 5 is equipped with a high-temperature resistant and anti-oxidation coating, which can effectively isolate the high temperature and oxidizing media during the cutting process, reduce the performance degradation of the coated end mill 5 caused by high temperature wear and oxidation corrosion, significantly extend its service life, and at the same time ensure the machining stability and accuracy in high-temperature cutting scenarios.
[0018] The guide rod 2 is available in various models, each with a different length. The guide rod 2 is detachably connected to the base 1 via screws, allowing for the selection of the appropriate guide rod 2 length based on the milling cutter displacement range requirements of different processing scenarios. Furthermore, the detachable connection of the guide rod 2 to the base 1 facilitates quick replacement of different models of guide rod 2, enabling adaptation to various processing needs without replacing the entire equipment. This enhances the equipment's versatility while reducing equipment procurement and maintenance costs.
[0019] Working principle: When using this milling cutter, first select the guide rod 2 of the corresponding length and model according to the milling cutter displacement range required by the machining scenario. Fix the guide rod 2 to the base 1 in a detachable manner with screws. Then, the operator can control the linkage seat 3 to rotate on the guide rod 2 through the handle 7. At the same time, the limiting cylinder 61 rotates, so that the spiral limiting groove 63 on the periphery of the guide rod 2 slides relative to the positioning rod 62 in the through hole of the limiting cylinder 61. The sliding of the positioning rod 62 drives the linkage seat 3 to move precisely along the guide rod 2. Then, the support rod 4 drives the coated milling cutter 5 to be adjusted to the target machining position. When the linkage seat 3 moves in the opposite direction, the pawl 65 slides on the ratchet 64, so that the ratchet 64 can be quickly reset.
