The push tooth knife guide 2 is provided with a second mounting hole for mounting the push tooth blade 1. The push tooth mandrel 4 is provided with a positioning groove that cooperates with the push tooth blade 1. The cutting edge of the push tooth blade 1 is designed to match the involute profile of the inner hole of the workpiece to be processed, and the hardness of the cutting edge is higher than that of the workpiece to be processed. The deburring push knife further includes a plurality of pressing plate screws 5 for fixing the push tooth pressing plate 3, which are evenly distributed around the periphery of the push tooth pressing plate 3. The outer peripheral surface of the push tooth knife guide 2 is provided with a plurality of guide grooves, which are evenly distributed along the axial direction of the push tooth knife guide 2. The material of the push tooth blade 1 is high-speed steel or cemented carbide, and its surface is hardened. In addition, the deburring push knife further includes a fine adjustment mechanism for adjusting the position of the push tooth blade 1, which is composed of a fine adjustment screw, a spring, and an adjustment block. One end of the push tooth mandrel 4 is provided with a multi-keyway structure connection interface for connecting to a power source, and the other end is provided with a guide head. The deburring push knife is also equipped with a cooling system, including a coolant channel passing through the push tooth mandrel 4, a plurality of liquid outlet holes provided on the push tooth knife guide 2, and an external coolant supply device communicated with the coolant channel. The surfaces of the push tooth pressing plate 3, the push tooth knife guide 2, and the push tooth mandrel 4 are all subjected to anti-corrosion treatment, such as chrome plating or nickel plating.

[0027] The push tooth pressing plate 3 is the basic component of the entire deburring push knife. It is connected to the push tooth knife guide 2 through the first mounting hole. This connection method ensures the stable positioning of the push tooth knife guide 2 on the push tooth pressing plate 3, and also facilitates disassembly and maintenance. A plurality of pressing plate screws 5 are evenly distributed around the periphery of the push tooth pressing plate 3, further enhancing the stability of the overall structure.

[0028] The connection between the push tooth knife guide 2 and the push tooth blade 1 is realized through the second mounting hole. This design enables the push tooth blade 1 to be easily installed and replaced, greatly improving the maintenance efficiency of the deburring push knife. The plurality of guide grooves on the outer peripheral surface of the push tooth knife guide 2 not only improve the stability during the processing, but also contribute to the distribution and chip removal of the coolant.

[0029] The push tooth blade 1, as the core working component, the fit between it and the push tooth mandrel 4 is crucial. The push tooth mandrel 4 is provided with positioning grooves that cooperate with the push tooth blade 1, and this design ensures the precise positioning and stability of the push tooth blade 1 during the working process. The edge design of the push tooth blade 1 matches the involute profile of the inner hole of the workpiece to be machined, and this ingenious design improves the efficiency and quality of deburring.

[0030] The push tooth mandrel 4, as the central axis of the entire deburring tool, the multi-keyway structure connection interface at one end is used to connect with the power source, ensuring the effective transmission of power. The guiding head at the other end helps the deburring tool to smoothly enter the inner hole of the workpiece to be machined. The coolant channel inside the push tooth mandrel 4 is connected to the liquid outlet holes on the push tooth tool guide 2, forming a complete cooling system.

[0031] The design of the fine-tuning mechanism is ingeniously integrated into the entire deburring tool structure. The fine-tuning screw passes through the push tooth tool guide 2 and is connected to the adjusting block, while the spring is placed between the fine-tuning screw and the push tooth tool guide 2. This design allows the operator to precisely adjust the position of the push tooth blade 1, and at the same time, the pre-tightening force provided by the spring can reduce vibration during the machining process.

[0032] The anti-corrosion treatment on the surfaces of all main components not only improves the corrosion resistance of each component, but also ensures the consistency of the appearance and performance of the entire deburring tool. This comprehensive anti-corrosion design greatly extends the service life of the deburring tool, enabling it to adapt to various harsh working environments.

[0033] Embodiment 2

[0034] As Figure 1 and 2 , the deburring tool includes:

[0035] Push tooth pressure plate 3:

[0036] The push tooth pressure plate 3 is an important part of the deburring tool and is used to fix and support other components. The push tooth pressure plate 3 is provided with first mounting holes for fixing the push tooth tool guide 2. The number and distribution of these first mounting holes should match the shape and size of the push tooth tool guide 2 to ensure a firm connection.

[0037] A plurality of pressing plate screws 5 for fixing are evenly distributed around the periphery of the push tooth pressure plate 3. The number and distribution of these pressing plate screws 5 should be reasonably designed according to the size of the deburring tool and the expected force to be borne to ensure the stability of the entire structure. The pressing plate screws 5 can be made of high-strength alloy steel materials to improve their load-bearing capacity and service life.

[0038] The surface of the push tooth pressure plate 3 is treated with anti-corrosion, and chromium plating or nickel plating process can be selected. This anti-corrosion treatment can not only improve the corrosion resistance of the push tooth pressure plate 3, but also enhance its surface hardness and extend its service life. In practical applications, a more suitable anti-corrosion process can be selected according to the specific conditions of the working environment.

[0039] Push tooth cutter guide 2:

[0040] The push tooth cutter guide 2 is an important component connecting the push tooth pressure plate 3 and the push tooth blade 1. It is provided with second mounting holes for installing the push tooth blade 1, and the design of these mounting holes should consider the shape and size of the push tooth blade 1 to ensure that the blade can be stably installed and is convenient for replacement.

[0041] The outer peripheral surface of the push tooth cutter guide 2 is provided with a plurality of guide grooves, which are evenly distributed along the axial direction of the push tooth cutter guide 2. The function of the guide grooves is to improve the stability and guiding property of the deburring cutter during the working process, and reduce vibration and deviation. The number, width and depth of the guide grooves should be optimized according to the size and working conditions of the deburring cutter to achieve the best guiding effect.

[0042] The push tooth cutter guide 2 is also treated with anti-corrosion, and the same chromium plating or nickel plating process as the push tooth pressure plate 3 can be adopted. This not only improves the corrosion resistance of the push tooth cutter guide 2, but also ensures the appearance consistency of the entire deburring cutter.

[0043] Push tooth blade 1:

[0044] The push tooth blade 1 is the core working component of the deburring cutter, and is directly responsible for removing the burrs of the inner hole of the workpiece. The push tooth blade 1 adopts a replaceable design, which greatly improves the maintenance convenience and service life of the deburring cutter.

[0045] The edge of the push tooth blade 1 is designed to match the involute profile of the inner hole of the workpiece to be machined. This design can ensure that the blade is closely attached to the surface of the inner hole of the workpiece, and improve the deburring effect and efficiency. The hardness of the edge is designed to be higher than that of the workpiece to be machined to ensure effective cutting and a long service life.

[0046] The material of the push tooth blade 1 can be selected from high-speed steel or cemented carbide. High-speed steel has good toughness and relatively high hardness, and is suitable for machining materials with general hardness; while cemented carbide has higher hardness and wear resistance, and is suitable for machining harder materials. Which material to choose should be determined according to the specific processing requirements and workpiece materials.

[0047] The surface of the push tooth blade 1 is treated with hardening, such as heat treatment or surface coating, etc. This treatment can further improve the surface hardness and wear resistance of the blade and extend its service life. In practical applications, appropriate hardening treatment methods and parameters can be selected according to the processing requirements.

[0048] Push tooth mandrel 4:

[0049] The push tooth mandrel 4 is the central axis of the deburring tool, playing the roles of support and transmission. The push tooth mandrel 4 is provided with a positioning groove that cooperates with the push tooth blade 1, and the design of this positioning groove should match the shape and size of the push tooth blade 1 to ensure accurate positioning and fixation of the blade.

[0050] One end of the push tooth mandrel 4 is provided with a connection interface for connecting to the power source, and this connection interface adopts a multi-keyway structure. The multi-keyway structure can effectively transmit torque to ensure stable power input to the deburring tool during operation. The number and size of the keyways should be designed according to the expected torque size to ensure the reliability of transmission.

[0051] The other end of the push tooth mandrel 4 is provided with a guide head, and the outer diameter of the guide head is smaller than the outer diameter of the main body of the push tooth mandrel 4. This design can guide the deburring tool to smoothly enter the inner hole of the workpiece to be processed, reducing the risk of jamming or skewing, and improving work efficiency and processing quality.

[0052] The push tooth mandrel 4 is also subjected to anti-corrosion treatment, using chromium plating or nickel plating process. This treatment not only improves the corrosion resistance of the push tooth mandrel 4 but also ensures the coordination between the components of the entire deburring tool.

[0053] Fine adjustment mechanism:

[0054] The fine adjustment mechanism is a key component for improving the processing accuracy of the deburring tool. It includes a fine adjustment screw, a spring, and an adjustment block. The fine adjustment screw passes through the push tooth tool guide 2 and is connected to the adjustment block, and the spring is placed between the fine adjustment screw and the push tooth tool guide 2 to provide a pre-tightening force.

[0055] This design allows the operator to precisely control the position of the push tooth blade 1 by adjusting the fine adjustment screw. The presence of the spring not only provides a pre-tightening force but also reduces vibration during the processing, further improving the processing accuracy. The design of the adjustment block should consider its cooperation with the push tooth blade 1 to ensure the accuracy and stability of the adjustment.

[0056] The material selection of the fine adjustment mechanism should consider the stress it bears and the working environment. For example, the fine adjustment screw can be made of high-strength alloy steel, the spring can be made of high-quality spring steel, and the adjustment block can be made of wear-resistant alloy, etc.

[0057] Cooling system:

[0058] The cooling system is an important part for improving the processing quality of the deburring tool and extending the tool life. It includes a coolant channel passing through the push tooth mandrel 4, a plurality of liquid outlet holes provided on the push tooth tool guide 2, and an external coolant supply device communicated with the coolant channel.

[0059] The design of the coolant channel should consider the principles of fluid mechanics to ensure that the coolant can flow smoothly and effectively reach the areas that need to be cooled. The number, size, and distribution of the liquid outlet holes should be optimized to ensure uniform and sufficient cooling effect.

[0060] The external coolant supply device can be an independent cooling system or integrated with the main cooling system of the machine tool. The selection of the coolant should consider factors such as the machining material and cutting conditions, and it can be ordinary cutting fluid or coolant with a special formula.

[0061] In practical applications, the flow rate and pressure of the coolant can be adjusted according to different machining requirements to achieve the best cooling effect. In addition, a filtration device can be considered to be added to the cooling system to extend the service life of the coolant and improve the cooling effect.

[0062] In summary, the deburring tool provided by the present utility model can effectively solve the problems existing in the prior art, improve the machining efficiency and quality, extend the service life of the tool, and adapt to different machining requirements through its unique structural design and the collaborative work of each component.
