Description

Technical Field

[0001] The utility model belongs to the technical field of static ring processing equipment, and particularly relates to a dry gas seal static ring processing tool. Background Technique

[0002] The dry gas seal static ring is a device for realizing static seal. It utilizes the pressure of gas and a special seal structure to achieve the sealing effect on the medium without generating friction. The dry gas seal static ring is usually used in static seal occasions that require avoiding lubricant pollution, oil-free pollution, and special environments such as high temperature, high speed, and high vacuum. This technology is widely used in fields such as aerospace, nuclear engineering, precision instruments, and semiconductor manufacturing. During the manufacturing process of the dry gas seal static ring, precise processing is required on its surface to form the required fixed threaded holes or other special-shaped holes and grooves. The shapes and sizes of these holes and grooves have strict requirements for easy installation and connection. The tool is an important tool to complete these processing operations. It can accurately cut the material according to the design requirements to form the required shape and size.

[0003] At present, the dry gas seal static ring processing tool cannot dampen the vibration received by the tool head during use, resulting in an unstable cutting process, which affects the machining surface quality, generates surface defects such as burrs and flaws, reduces the machining accuracy and surface finish, and also increases the wear speed of the tool, leading to a significant shortening of the tool life and increasing the frequency and cost of tool replacement. Content of the Utility Model

[0004] The technical problem to be solved by the utility model is that the dry gas seal static ring processing tool cannot dampen the vibration received by the tool head during use.

[0005] The technical solution adopted by the utility model to solve its technical problem is: a dry gas seal static ring processing tool, including a tool head. One end of the tool head is fixedly installed with a connecting rod. One end of the connecting rod is provided with a single-head split nut. The inner side of the single-head split nut is provided with a shock-absorbing mechanism. The shock-absorbing mechanism includes an installation hole opened on one side of the single-head split nut. The inner side of the installation hole is provided with a rubber bushing. Through the setting of the rubber bushing, it can avoid the adverse effects of the vibration generated during the processing on the tool head and the machining surface, and help improve the flatness and accuracy of the machining surface.

[0006] Preferably, the connecting rod penetrates through the rubber bushing and extends to the inner side of the single-head split nut. Through the setting of the connecting rod, the tool head and the single-head split nut can be stably connected, thus ensuring the stability during the cutting operation.

[0007] Preferably, one end of the connecting rod is sleeved with a collet. The collet includes an outer sleeve and a clamping pliers. The clamping pliers inside the collet will firmly clamp the connecting rod to ensure that it will not loosen or displace during the processing, thus ensuring the accuracy and safety of the processing.

[0008] Preferably, the collet is sleeved on the outside of the connecting rod and is located inside the single-head open nut. Through the interaction of components such as the connecting rod, single-head open nut, screw rod, collet, and tool holder, the stable connection and fixation of the tool bit are realized, thereby improving the accuracy and safety of the cutting operation.

[0009] Preferably, a screw rod is threadedly connected inside the single-head open nut, and a tool holder is fixedly installed at one end of the screw rod. By tightly screwing and pressing the single-head open nut on the outside of the screw rod, the collet can be fixed and kept in a stable position to prevent any loosening or deviation during the processing, thereby ensuring the accuracy and stability of the processing.

[0010] Preferably, a groove is provided at one end of the screw rod, and the groove is movably installed on the outside of one end of the collet. Through the setting of the groove, the collet can be fixed and limited, further enhancing the stability and reliability of the structure.

[0011] Preferably, the material of the tool bit is a mixture of tungsten carbide and cobalt, and a protective coating is provided on the surface of the tool bit. By mixing tungsten carbide and cobalt, the overall hardness of the tool bit can be significantly improved, thereby significantly improving the wear resistance and service life of the tool bit.

[0012] Preferably, the protective coating includes a heat-resistant coating coated on the surface of the tool bit, and a wear-resistant coating is coated on the surface of the heat-resistant coating. The material of the heat-resistant coating is titanium nitride, and the material of the wear-resistant coating is alumina. Through the setting of titanium nitride, excellent high-temperature resistance performance can be provided, which can protect the surface of the tool bit from being damaged easily under high-temperature processing conditions, thereby prolonging the service life of the tool bit. Through the setting of alumina, its high-hardness characteristic can be used to further improve the wear resistance of the tool bit.

[0013] The beneficial effects of the present utility model are:

[0014] 1. For this dry gas seal stationary ring processing tool, through the setting of the shock absorption mechanism, the vibration generated during the processing can be avoided from having an adverse impact on the tool bit and the processing surface, which helps to improve the flatness and accuracy of the processing surface. It can not only reduce the influence of vibration on the tool bit and prolong the service life of the tool bit, but also make the cutting more stable. In fine processing and high-precision processing, it is beneficial to obtain higher processing quality.

[0015] 2. The cutting tool for the stationary ring of dry gas seal can effectively improve the high-temperature resistance of the tool tip through the setting of the heat-resistant coating.

Through the setting of the wear-resistant coating, the wear resistance of the tool tip can be effectively improved, the service life of the tool tip can be extended, the frequency of replacing the tool tip can be reduced, and thus the production cost can be reduced.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0022] Now, the present utility model will be further described in detail with reference to the accompanying drawings and preferred embodiments. These drawings are all simplified schematic diagrams, only illustrating the basic structure of the present utility model in a schematic manner, so they only show the components related to the present utility model.

[0023] As Figures 1 to 5 shown, a cutting tool for the stationary ring of dry gas seal provided by the present utility model includes a tool tip 1. One end of the tool tip 1 is fixedly installed with a connecting rod 2. One end of the connecting rod 2 is provided with a single-head open nut 3. The inner side of the single-head open nut 3 is provided with a shock-absorbing mechanism 4. The shock-absorbing mechanism 4 includes a mounting hole 401 opened on one side of the single-head open nut 3, and a rubber bushing 402 is arranged inside the mounting hole 401.

[0024] Refer to Figures 1 to 3, the connecting rod 2 passes through the rubber bushing 402 and extends to the inside of the single-end open nut 3. A collet 5 is sleeved at one end of the connecting rod 2. The collet 5 includes an outer sleeve and clamping pliers. The collet 5 is sleeved on the outside of the connecting rod 2 and is located inside the single-end open nut 3. A screw rod 6 is threadedly connected to the inside of the single-end open nut 3. A knife handle 8 is fixedly installed at one end of the screw rod 6. A groove 7 is formed at one end of the screw rod 6, and the groove 7 is movably installed on the outside of one end of the collet 5.

[0025] With the above solution: Through the setting of the connecting rod 2, the tool bit 1 can be stably connected to the single-end open nut 3, thereby ensuring the stability during the cutting operation. In this operation, the single-end open nut 3 is tightly screwed and pressed on the outside of the screw rod 6, so as to fix the collet 5 and keep it in a stable position, preventing any loosening or deviation during the processing, thereby ensuring the accuracy and stability of the processing. At this time, the clamping pliers inside the collet 5 will firmly clamp the connecting rod 2 to ensure that it will not loosen or displace during the processing, thus guaranteeing the accuracy and safety of the processing. In addition, the setting of the groove 7 can fix and limit the collet 5, further enhancing the stability and reliability of the structure. Through the interaction of components such as the connecting rod 2, the single-end open nut 3, the screw rod 6, the collet 5, and the knife handle 8, the stable connection and fixation of the tool bit 1 are achieved, thereby improving the accuracy and safety of the cutting operation.

[0026] Reference Figure 1 , Figure 2 , Figure 4 and Figure 5 , the material of the tool bit 1 is a mixture of tungsten carbide and cobalt. A protective coating 9 is provided on the surface of the tool bit 1. The protective coating 9 includes a heat-resistant coating 901 coated on the surface of the tool bit 1, and a wear-resistant coating 902 is coated on the surface of the heat-resistant coating 901. The material of the heat-resistant coating 901 is titanium nitride, and the material of the wear-resistant coating 902 is aluminum oxide.

[0027] Adopting the above solution: By mixing tungsten carbide with cobalt, the overall hardness of the tool tip 1 can be significantly improved, thereby significantly enhancing the wear resistance and lifespan of the tool tip 1. In addition, tungsten carbide also has good high-temperature resistance and can maintain high hardness and wear resistance in high-temperature environments. Therefore, it is suitable for high-temperature cutting processing. The mixture of tungsten carbide and cobalt usually also has good corrosion resistance and can cope with corrosion problems in some special processing environments. By setting titanium nitride, excellent high-temperature resistance can be provided, which can protect the surface of the tool tip 1 from being easily damaged under high-temperature processing conditions, thereby extending the service life of the tool tip 1. In addition, titanium nitride also has high hardness, which can effectively improve the wear resistance of the tool tip 1, reduce the wear of the tool tip 1, and improve the processing efficiency. At the same time, titanium nitride also has certain corrosion resistance, which can reduce the risk of the tool tip 1 being corroded and maintain the good state of the surface of the tool tip 1. By setting alumina, the wear resistance of the tool tip 1 can be further improved by utilizing its high-hardness characteristics, the friction and wear between the tool tip 1 and the workpiece during cutting can be reduced, thereby extending the service life of the tool tip 1. At the same time, alumina can maintain high hardness and stability under high-temperature conditions, which helps to protect the surface of the tool tip 1 from being deformed and damaged due to heat influence. In addition, the surface of the alumina coating is smooth, which can reduce the friction between the tool tip 1 and the workpiece, help to improve the surface quality of the processing, and also help to reduce the wear of the tool tip 1.

[0028] Working principle:

[0029] During use, the tool tip 1 is firmly connected to the single-head split nut 3 through the connecting rod 2 to ensure stability during the cutting operation. Tighten the single-head split nut 3 tightly and press it firmly on the outside of the screw rod 6, then the collet 5 can be fixed and kept in a stable position to prevent any looseness or deviation during the processing, thereby ensuring the accuracy and stability of the processing. At this time, the clamping pliers inside the collet 5 will firmly clamp the connecting rod 2 to ensure that it does not loosen or displace during the processing, thereby guaranteeing the accuracy and safety of the processing. The collet 5 can be fixed and limited through the groove 7, further enhancing the stability and reliability of the structure. The rubber bushing 402 can avoid the adverse effects of vibrations generated during the processing on the tool tip 1 and the processing surface. By mixing tungsten carbide with cobalt, the overall hardness of the tool tip 1 can be significantly improved, thereby significantly enhancing the wear resistance and lifespan of the tool tip 1. By setting titanium nitride, excellent high-temperature resistance can be provided, which can protect the surface of the tool tip 1 from being easily damaged under high-temperature processing conditions, thereby extending the service life of the tool tip 1. The wear resistance of the tool tip 1 can be further improved by the high-hardness characteristics of alumina, the friction and wear between the tool tip 1 and the workpiece during cutting can be reduced, and at the same time, a certain protection can be provided for the heat-resistant coating 901 to extend the service life of the heat-resistant coating 901.

[0030] In summary, for the dry gas seal stationary ring machining tool, through the interaction of components such as the connecting rod 2, single-headed split nut 3, screw rod 6, collet 5, and tool shank 8, the stable connection and fixation of the tool tip 1 are achieved, thereby improving the accuracy and safety of the cutting operation. Through the setting of the shock absorption mechanism 4, it is possible to avoid the adverse effects of vibrations generated during the machining process on the tool tip 1 and the machined surface, which helps to improve the flatness and accuracy of the machined surface. It can not only reduce the impact of vibrations on the tool tip 1 and extend the service life of the tool tip 1, but also make the cutting more stable. In fine machining and high-precision machining, it is beneficial to obtain higher machining quality. Through the setting of the heat-resistant coating 901, the high-temperature resistance of the tool tip 1 can be effectively improved. Especially in the working conditions of high-speed cutting and machining high-temperature alloy materials, the heat-resistant coating 901 can protect the tool tip 1 from deformation, softening, or oxidation. Through the setting of the wear-resistant coating 902, the wear resistance of the tool tip 1 can be effectively improved, the service life of the tool tip 1 can be extended, and the frequency of replacing the tool tip 1 can be reduced, thereby reducing the production cost.
