Description

Technical Field

[0001] This utility model relates to the field of mechanical manufacturing technology, and in particular to a precision cutting tool for CNC machining of reducer flanges. Background Technology

[0002] CNC machining tools are important tools used for cutting processes in mechanical manufacturing. Their design, manufacturing, and application involve multiple disciplines such as materials science, mechanical engineering, and CNC technology. Precision cutting tools for CNC machining of reducer flanges are mainly used for high-precision machining of reducer flanges. They need to meet the requirements of high precision and high efficiency of CNC machining. Their research and development and application are of great significance for improving the machining quality and production efficiency of reducer flanges. Its main function is to efficiently complete multiple processes of flange plane milling and inner hole boring by relying on the program control of CNC equipment and through the precise relative movement of the cutting edge of the tool and the flange workpiece. While ensuring the accuracy control of machining dimensional tolerances, it reduces the surface roughness of the flange, ensures the sealing performance and connection reliability of the flange during subsequent assembly, and ultimately improves the operating efficiency and service life of the entire reducer transmission system. Traditional cutting tools generally adopt a single, integrated structural design, with the tool head and body fixedly connected. This makes it difficult to flexibly adjust and adapt to different sizes and irregular contours of the products to be machined. This structural limitation not only requires frequent replacement of the entire tool with the corresponding specifications, increasing procurement costs, but also results in extremely poor compatibility of a single tool with the processing needs of multiple varieties and small batches of products. In addition, the cooling method of traditional tools is mostly external spraying, and the coolant can only act on the surface cutting area of ​​the workpiece and the tool, making it difficult to penetrate to the root of the tool edge and the deep cavity machining position, resulting in a large amount of coolant waste, insufficient cooling, and easy to cause tool overheating and wear, affecting product quality. To solve the above problems, a precision cutting tool for CNC machining of reducer flanges is proposed. Utility Model Content

[0003] To overcome the above shortcomings, this utility model provides a precision cutting tool for CNC machining of reducer flanges. It aims to improve the existing technology that uses an integrated design with the tool head and tool body fixed, which makes it difficult to flexibly adjust according to the different sizes and irregular contours of the products to be processed. In addition, the coolant is mostly sprayed externally and cannot penetrate into the tool, resulting in insufficient cooling.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: a precision cutting tool for CNC machining of a reducer flange, comprising a tool holder, a tool head seat threadedly connected to the outer wall of the tool holder, a tool head fixedly connected to the bottom of the tool head seat, a locking pin slidably connected to the inner wall of the tool head seat, a spring sleeved on the outer wall of the locking pin, a fixing block fixedly connected to the outer wall of the tool head seat, and a lock shell fixedly connected to the outer wall of the fixing block; As a further description of the above technical solution: A flow tube is fixedly connected to the inner wall of the handle, a sealing ring is fixedly connected to the top of the flow tube, a piston head is slidably connected to the inner wall of the flow tube, a locking block is fixedly connected to the outer wall of the piston head, and an elastic lock is fixedly connected to the outer wall of the flow tube. The locking block and the elastic lock engage with each other, and multiple guide tubes are inserted inside the flow tube. As a further description of the above technical solution: One end of the spring is fixedly connected to the outer wall of the fixing block, and the other end of the spring is fixedly connected to the inner wall of the lock housing; As a further description of the above technical solution: The locking pin is slidably connected to the inner wall of the fixed block, and the locking pin is slidably connected to the inner wall of the lock housing; As a further description of the above technical solution: The cutting head is threaded onto the outer wall of the cutting handle; As a further description of the above technical solution: A handle is fixedly connected to one end of the locking pin near the lock housing; As a further description of the above technical solution: The guide tube passes through the tool holder.

[0005] This utility model has the following beneficial effects: 1. In this utility model, the adaptive elastic potential energy generated by the interaction between the spring, the lock housing, and the fixing block can be used to separate and engage the locking pin with the cutter head seat through the handle, achieving quick disassembly and assembly. This design allows for quick replacement of cutter heads of different specifications, sizes, and shapes, not only adapting to product diversity but also reducing replacement costs.

[0006] 2. In this utility model, the piston head can be made more stable by the reinforcement effect of the locking block and the elastic lock buckle, and the sealing of the delivery pipe when it is not in use is increased to prevent impurities from entering. In addition, the delivery pipe and the guide pipe are designed inside the tool holder, which can effectively deliver the coolant to the deep cavity of the tool head, making the coolant distribution more uniform and extending the service life of the tool.

[0009] 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.

[0010] Reference Figures 1-3 This utility model provides an embodiment of a precision cutting tool for CNC machining of a reducer flange, including a tool holder 1, a tool head seat 3 threadedly connected to the outer wall of the tool holder 1, and a tool head 4 fixedly connected to the bottom of the tool head seat 3. This detachable connection design ensures structural stability and facilitates quick replacement of tool heads 4 of different specifications according to machining needs. A locking pin 5 is slidably connected to the inner wall of the tool head seat 3, and a spring 7 is sleeved on the outer wall of the locking pin 5. The elastic force of the spring 7 can keep the locking pin 5 in a pre-tight state, ensuring the reliability of the locking mechanism. A fixing block 8 is fixedly connected to the outer wall of the tool head seat 3, and a lock shell 6 is fixedly connected to the outer wall of the fixing block 8. The fixing block 8 and the lock shell 6 together constitute the mounting base of the locking mechanism, providing a stable sliding guide for the locking pin 5 and a force basis for the spring 7. This design can effectively realize the quick assembly and disassembly of the tool head 4, increase the diversity of processed products, and enhance the flexibility of tool use.

[0011] Reference Figure 2 , Figure 4 and Figure 5A coolant delivery pipe 9 is fixedly connected to the inner wall of the tool holder 1. The coolant delivery pipe 9 serves as the main channel for coolant delivery, introducing external coolant into the tool. A sealing ring 12 is fixedly connected to the top of the coolant delivery pipe 9, effectively preventing coolant leakage from the connection point during delivery and improving sealing performance. A piston head 10 is slidably connected to the inner wall of the coolant delivery pipe 9. The piston head 10's main function is to open and close the coolant delivery pipe 9. A locking block 11 is fixedly connected to the outer wall of the piston head 10, moving synchronously with the piston head 10 to facilitate the delivery of coolant. The flow tube 9 provides a locking function by opening and closing. The outer wall of the flow tube 9 is fixedly connected with a spring lock 13. The spring lock 13 has a certain elastic deformation capability and can form a stable engagement relationship with the locking block 11. The locking block 11 and the spring lock 13 are engaged. This engagement structure can quickly realize the positioning and unlocking of the piston head 10, which is convenient for the operator to add coolant. Multiple guide tubes 14 are inserted inside the flow tube 9. The multiple guide tubes 14 can divert the coolant to different cutting areas of the cutter head 4, improving the overall cooling.

[0012] Reference Figure 3 One end of the spring 7 is fixedly connected to the outer wall of the fixing block 8, and the other end of the spring 7 is fixedly connected to the inner wall of the lock housing 6. This installation method of fixing at both ends can ensure that the spring 7 always maintains a stable elastic potential energy output when the locking pin 5 slides, thus ensuring the reset function of this structure.

[0013] Reference Figure 3 The locking pin 5 is slidably connected to the inner wall of the fixed block 8 and the inner wall of the lock housing 6. The double sliding connection design provides the locking pin 5 with a precise linear movement trajectory, preventing it from deviating or getting stuck during operation.

[0014] Reference Figures 1-2 The cutting head 4 is threaded onto the outer wall of the tool holder 1. The threaded connection not only facilitates the quick assembly and disassembly of the cutting head 4, but also allows for a tight fit between the cutting head 4 and the tool holder 1 through rotation adjustment, ensuring machining accuracy.

[0015] Reference Figure 3 A handle 2 is fixedly connected to one end of the locking pin 5 near the lock housing 6. The handle 2 provides the operator with a convenient point of force application, making it easy to manually control the sliding of the locking pin 5 and realize the quick locking and unlocking of the cutter head seat 3 and the cutter handle 1.

[0016] Reference Figure 2 and Figure 5 The guide tube 14 passes through the tool holder 1. The through-type design allows the guide tube 14 to directly transport the coolant from inside the tool holder 1 to the cutting area of ​​the tool head 4, reducing the resistance and loss in the cooling path.

[0017] Working principle: First, fix the cutter head seat 3 and the cutter head 4 to the outer wall of the cutter handle 1 by threaded connection. Push the locking pin 5 along the inner wall of the fixing block 8 and the lock housing 6 by the handle 2, compressing the spring 7 on the outer wall of the locking pin 5. After the cutter head seat 3 and the cutter handle 1 are in place, release the handle 2. The spring 7 releases its elastic force and pushes the locking pin 5 to reset, locking the cutter head seat 3 and the cutter handle 1. The fixing block 8 and the lock housing 6 provide guidance for the locking pin 5 to ensure a firm lock. When replacement is needed, pull the handle 2 to separate the locking pin 5 from the cutter head seat 3 to achieve disassembly.

[0018] The piston head 10 positions and opens the channel of the delivery pipe 9, allowing external coolant to enter the tool holder 1 through the delivery pipe 9. The coolant is then diverted through multiple guide pipes 14 within the delivery pipe 9. The guide pipes 14 penetrate the tool holder 1 and reach the cutting area and deep cavity of the tool head 4, achieving precise cooling. After cooling is complete, the sealing ring 12 at the top of the delivery pipe 9 is sealed and connected to the external cooling pipe. The piston head 10 is adjusted to slide on the inner wall of the delivery pipe 9, causing the locking block 11 to move. When the locking block 11 engages with the elastic latch 13 on the outer wall of the delivery pipe 9, the delivery pipe 9 is closed.

[0019] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
