Technical Field
[0001] This utility model relates to the field of end face gear machining tool technology, and in particular to a quick-release high-precision end face gear machining tool. Background Technology
[0002] Face gears are gears whose teeth are distributed on the end face of a part. Their main function is to transmit power and convert motion. Unlike traditional gears where teeth are distributed on a circumferential surface, the teeth of face gears are located on the end face of the workpiece. This requires specialized cutting techniques and high-precision cutting tools during machining to ensure that the dimensions, shape, and angles of each tooth meet stringent design requirements. Face gears are commonly used in high-precision mechanical equipment, such as aerospace, automotive transmissions, and high-speed machine tools, offering advantages such as stable transmission, low noise, and smooth operation.
[0003] Existing face gear machining tools generally adopt a fixed structure design. Although this structure has certain advantages in terms of integrity and machining stability, it is difficult to achieve quick disassembly and efficient clamping in actual use. This not only prolongs the machining cycle of face gears, but also easily leads to errors and vibrations during machining, thus affecting the machining accuracy and surface quality of the gears. At the same time, existing tool structures usually lack effective cooling and chip removal devices, and cannot provide timely airflow to dissipate heat from the cutting head. This causes the cutting head to accumulate heat under high-intensity machining, and metal chips easily adhere to the surface of the cutting head, thereby affecting tool life and machining stability. It also further exacerbates the problems of decreased machining accuracy and difficult equipment maintenance. Therefore, it has certain limitations in use.
[0004] Based on this, we propose a quick-release high-precision machining tool for end-face gears to solve the aforementioned problems. Utility Model Content

[0011] Optionally, the inner side of the tool mounting bracket is connected to an end face gear via a bearing. The top of the tool mounting bracket has four sets of positioning slots, which match the structure of the positioning insert plate. The positioning slots and the positioning insert plate are in a snap-fit engagement. A forward and reverse motor is installed on the top side of the tool mounting bracket near the positioning slots.

[0026] 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.
[0027] Example: Refer to Figures 1 to 7 This utility model provides an embodiment of a quick-release high-precision machining tool for end-face gears, including a tool mounting bracket 1. A gear cutting assembly 2 is mounted in the middle of the tool mounting bracket 1. An air-cooling assembly 3 is connected to the top of the tool mounting bracket 1 near the gear cutting assembly 2. The gear cutting assembly 2 includes a gear cutting component 4. A pipe positioning component 5 is connected to one side of the gear cutting component 4. The gear cutting component 4 includes a protective metal cover 6. A cutting disc 7 is connected to the inside of the protective metal cover 6 via a bearing. A cutting motor 8 is mounted on one side of the protective metal cover 6. The output end of the motor 8 is connected to the cutting disc 7 via a transmission connection. The protective metal cover 6 is also provided with a first quick-release clamping plate 9 on the side away from the cutting motor 8. The machining tool is used through the cooperation between the first quick-release clamping plate 9 and the second quick-release clamping plate 25. Since the second quick-release clamping plate 25 and the first quick-release clamping plate 9 are in a snap-fit fit, the protective metal cover 6, which is equipped with the cutting disc 7 and the cutting motor 8, can be limited and snapped into the middle of the tool mounting frame 1. The tool mounting frame 1 can be used to disassemble, connect, repair and replace the protective metal cover 6 according to the usage of the cutting disc 7.
[0028] The pipe positioning component 5 includes a connecting pipe support 10. A fixing plate 11 is provided on one side of both the connecting pipe support 10 and the protective metal cover 6. An arc-shaped groove 12 is formed in the middle of the connecting pipe support 10, and elastic clamping blocks 13 are respectively provided on both sides of the inner wall of the arc-shaped groove 12. The pipe positioning component 5 consists of the connecting pipe support 10, fixing plate 11, arc-shaped groove 12, and elastic clamping blocks 13. Its main function is to accurately position and firmly constrain the guide shield 18 installed at one end of the elastic air duct 17, ensuring that the air outlet of the guide shield 18 can always accurately align with the contact area between the cutting disc 7 and the end face gear 19, preventing displacement due to vibration or external force during processing, thereby ensuring stable output and precise guidance of the cooling airflow. The air-cooling assembly 3 includes a blower box 14. Positioning inserts 15 are respectively provided at the four corners of the bottom of the blower box 14, and an air inlet pipe is connected to the air inlet of the blower box 14. The air outlet of the blower box 14 is connected to a flexible air duct 17. The flexible air duct 17 matches the structure of the arc-shaped groove 12. The flexible air duct 17 and the arc-shaped groove 12 are in a snap-fit fit. A guide shroud 18 is also installed at the end of the flexible air duct 17 away from the blower box 14. The air-cooling component 3 works in conjunction with the blower box 14, the air inlet pipe 16, the flexible air duct 17, and the guide shroud 18. When the air-cooling component 3 is powered on, it can provide air cooling to the contact area between the cutting disc 7 and the end gear 19. The component can also blow away metal debris adhering to the surface of the cutting disc 7 or the end gear 19. This not only reduces the temperature of the contact area between the cutting disc 7 and the end gear 19, but also prevents metal debris from adhering to the surface of the cutting disc 7 or the end gear 19, thereby improving the stability and surface quality of the machining.
[0029] The inner side of the tool mounting bracket 1 is connected to an end face gear 19 via a bearing. Four sets of positioning slots 20 are provided on the top of the tool mounting bracket 1. The positioning slots 20 and positioning inserts 15 are structurally matched and are engaged in a snap-fit relationship. A forward / reverse motor 21 is installed on the top side of the tool mounting bracket 1 near the positioning slots 20. Two sets of guide grooves 22 are provided on the side of the tool mounting bracket 1 near the forward / reverse motor 21. One set of guide grooves 22 has a guide slide rod 23 connected inside, and the other set of guide grooves 22 has an adjusting screw 24 connected inside via a bearing. The adjusting screw 24 is connected to the output end of the forward / reverse motor 21 via a transmission connection. A second quick-release plate 25 is also provided between the two sets of guide grooves 22. Through the cooperation between the guide grooves 22, guide slide rods 23, adjusting screws 24, guide slide holes 26 and adjusting screw holes 27, since the guide slide hole 26 and guide slide rod 23 are in sliding fit and the adjusting screw hole 27 and adjusting screw 24 are in thread fit, when the forward and reverse motors 21 are powered on in the forward or reverse direction, the gear cutting assembly 2 installed in the middle of the tool mounting bracket 1 can be raised and lowered. This design allows the equipment to flexibly adjust the cutting depth of the cutting disc 7 on the end face gear 19, thereby adapting to end face gears 19 of different specifications and processing requirements.
[0030] The second quick-release plate 25 is structurally matched with the first quick-release plate 9, and the second quick-release plate 25 and the first quick-release plate 9 are in a snap-fit engagement. Through this snap-fit structure, the protective metal cover 6, which houses the cutting disc 7 and the cutting motor 8, can be locked and secured in the middle of the tool mounting bracket 1. This tool mounting bracket 1 allows for convenient disassembly, assembly, repair, and replacement of the protective metal cover 6 according to the usage of the cutting disc 7. One end of the second quick-release plate 25 has two sets of guide sliding holes 26, which are structurally matched with the guide sliding rod 23. The guide sliding holes 26 and the guide sliding rod 23 are connected... For sliding engagement, the second quick-release plate 25 has two sets of adjusting screw holes 27 at the end away from the guide sliding hole 26. The adjusting screw holes 27 and the adjusting screw 24 are structurally matched and have a threaded engagement. When the forward and reverse motor 21 is energized in the forward or reverse direction, the gear cutting assembly 2 installed in the middle of the tool mounting bracket 1 can be adjusted in height by the sliding engagement between the guide sliding hole 26 and the guide sliding rod 23, and the threaded engagement between the adjusting screw holes 27 and the adjusting screw 24. It also provides rapid positioning, precise adjustment and stability for the machining tool, reducing vibration and errors during the machining process.
[0031] Working principle: The quick-release high-precision machining tool for end face gears designed in this scheme mainly consists of a tool mounting bracket 1, a gear cutting assembly 2, and an air-cooling assembly 3. The gear cutting assembly 2 includes a gear cutting component 4 and a pipe positioning component 5. The gear cutting component 4 is connected to the protective metal cover 6 by a first quick-release clamping plate 9 and a second quick-release clamping plate 25 between two sets of guide grooves 22. Since the second quick-release clamping plate 25 and the first quick-release clamping plate 9 are structurally matched and are interlocked, the protective metal cover 6, which contains the cutting disc 7 and the cutting motor 8, can be limited and clamped in the middle of the tool mounting bracket 1. When the cutting motor 8 is powered on, since the output end of the cutting motor 8 is connected to the cutting disc 7, it can drive the cutting disc 7 to rotate inside the protective metal cover 6. The rotating cutting disc 7 can perform cutting processing on the end face gear 19 set inside the tool mounting bracket 1.
[0032] This solution utilizes a forward and reverse motor 21 mounted on the top of the tool mounting bracket 1. This motor 21 operates through the cooperation of a guide groove 22, a guide slide rod 23, an adjusting screw 24, a guide slide hole 26, and an adjusting screw hole 27. Since the guide slide hole 26 and the guide slide rod 23 are in a sliding fit, and the adjusting screw hole 27 and the adjusting screw 24 are in a threaded fit, when the forward and reverse motor 21 is energized in either the forward or reverse direction, the gear cutting assembly 2 installed in the middle of the tool mounting bracket 1 can be adjusted in height. This design allows the equipment to flexibly adjust the cutting depth of the cutting disc 7 on the end face gear 19, thereby adapting to end face gears 19 of different specifications and processing requirements.
[0033] In this solution, the air-cooling component 3 works in conjunction with the blower box 14, the air intake pipe 16, the flexible air duct 17, and the air guide shroud 18. When the air-cooling component 3 is powered on, it can provide air cooling to the contact area between the cutting disc 7 and the end gear 19. At the same time, the component can also blow away metal debris adhering to the surface of the cutting disc 7 or the end gear 19. This not only reduces the temperature of the contact area between the cutting disc 7 and the end gear 19, but also prevents metal debris from adhering to the surface of the cutting disc 7 or the end gear 19, thereby improving the stability and surface quality of the machining process.
[0034] 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.
