Description

Technical Field

[0001] The present invention relates to the technical field of coaxial connectors, and particularly to a grooving processing device for the inner conductor of a coaxial connector. Background Art

[0002] A coaxial connector refers to a part used to connect the ends of two shafts to ensure that the center lines of the two shafts are on the same axis. Generally, it is used to connect the driving shaft and the driven shaft to transmit the rotational motion of the driving shaft to the driven shaft. In the field of current electronic device manufacturing, as a common electronic component, coaxial connectors are widely used in various electronic products and play a key role in signal transmission.

[0003] The most common coaxial connectors in daily life, such as Figure 1 shown, generally have a connecting core in the middle, and a hollow cylindrical conductor around it. As Figure 13 and 14 shown, there are notches on the conductor wall of the coaxial connector. However, when grooving the conductor of such coaxial connectors, the existing processing methods have the following deficiencies:

[0004] In the prior art, when grooving a conductor, grooving tools such as cutting tools or stamping tools are usually used. Grooving is carried out from the outside of the conductor to the inside of the conductor, or perpendicular to the conductor along the axis direction of the conductor from top to bottom (at the moment when the grooving tool contacts the conductor wall, the material at the conductor is subjected to concentrated shear force, causing this part of the material to separate from the conductor body. The separated material, that is, foreign matters such as burrs, scraps, and metal chips generated, part of it will go to the outside of the conductor along the notch; while the other part will enter the inside of the conductor along the notch). In the above two grooving methods during the processing, it is extremely easy for the burrs, scraps, and metal chips generated during grooving to enter the inside of the conductor. Since the internal space of the conductor is narrow and the structure is a closed circle, it is difficult to clean these foreign matters inside the conductor, consuming a large amount of labor and time costs. Moreover, it is not easy to effectively polish the inner wall of the conductor, seriously affecting the production efficiency of coaxial connectors and increasing the defective rate of products, which urgently needs to be solved in actual production. Summary of the Invention

[0005] Aiming at the deficiencies of the prior art, the present invention provides a grooving processing device for the inner conductor of a coaxial connector, which solves the problems that foreign matters generated during traditional grooving of the conductor enter the inside of the conductor, as well as subsequent problems such as inconvenient cleaning and polishing.

[0006] To achieve the above object, the present invention provides the following technical solution: A grooving processing device for the inner conductor of a coaxial connector, including an insert. One end of the insert can enter the coaxial connector. A plurality of grooving knives are installed around the insert. The grooving knives are inclined, and one end of the grooving knife is close to the entering end of the insert, and the other end of the grooving knife is far from the insert. Drive the insert to enter the coaxial connector, drive the grooving knives to move synchronously, and the grooving knives cut a slot from the inside to the outside on the conductor of the coaxial connector.

[0007] Further, a blocking block is slidably installed at the entering end of the insert. An installation arm is fixedly arranged on the outer wall of the insert. The blocking block and one end of the grooving knife are hinged. A guiding groove for guiding the other end of the grooving knife is opened on the installation arm.

[0008] Further, a fixing member is fixedly arranged on the outer wall of the insert. A spring is arranged between the fixing member and the blocking block.

[0009] Further, the bottom end of the blocking block is lower than the entering end of the insert.

[0010] Further, a cavity for inserting the connection core on the coaxial connector is arranged inside the insert.

[0011] Further, a hollow sleeve is fixedly arranged on the insert. A grinding assembly for grinding the outer wall of the conductor of the coaxial connector is installed inside the sleeve.

[0012] Further, the grinding assembly includes an installation frame and a grinding sheet detachably installed on the installation frame.

[0013] Further, the installation frame and the sleeve are connected by a driving rod. The driving rod is slidably connected to the sleeve. A through groove for the driving rod to slide is opened on the sleeve. The grinding assembly is driven to move by the driving rod to control the distance between the grinding assembly and the outer wall of the conductor of the coaxial connector.

[0014] Further, a driving shaft is coaxially connected to the insert. The insert is connected to a motor through the driving shaft. The driving shaft is coaxially connected to the rotating end of the motor.

[0015] Further, it further includes a driving device for driving the displacement of the insert.

[0016] Compared with the prior art, the present invention provides a grooving processing device for the inner conductor of a coaxial connector, having the following beneficial effects:

[0017] The grooving processing device for the inner conductor of a coaxial connector is provided with an insert. A plurality of grooving knives are installed around the insert. The grooving knives are inclined, with one end of the grooving knife close to the insertion end of the insert and the other end away from the insert. When grooving, the insert is driven into the coaxial connector, driving the grooving knives to move synchronously, so that the grooving knives groove the conductor from the inside to the outside. Compared with the traditional grooving methods (from the outside to the inside or from top to bottom), it effectively avoids the problem of foreign objects such as burrs, surplus materials, and metal chips entering the inner side of the conductor during traditional processing, fundamentally eliminating the subsequent processing inconvenience caused by foreign objects entering the inner side of the conductor.

[0018] 1. Facilitate cleaning and grinding: The foreign objects generated by cutting are located outside the conductor. Compared with the traditional cutting from the outside to the inside or axially, which causes foreign objects to fall into the inner side of the conductor, the operating space for cleaning and grinding is more open, and the operation difficulty is greatly reduced. There is no need for complex internal cleaning tools and cumbersome processes, greatly improving the efficiency of cleaning and grinding, and saving a large amount of time and labor costs.

[0019] 2. Improve processing efficiency and product quality: The fast and convenient cleaning and grinding process shortens the entire processing cycle and significantly improves the processing efficiency. At the same time, it effectively avoids foreign objects entering the conductor interior and can grind the conductor well, improving the product quality and thus increasing the product qualification rate.

[0035] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0036] The existing coaxial connector 35, its structural design, such as Figure 1As shown. A connection core 37 made of metal is provided in the middle of the coaxial connector 35. Around the connection core 37, a conductor 36 in the shape of a hollow cylinder surrounding the connection core 37 is provided. The conductor 36 plays a key role in signal transmission and can also provide effective physical support.

[0037] During the manufacturing process of the coaxial connector 35, the processing of its conductor 36 is an important link. From before processing to after processing, the conductor 36 has changed significantly. For details, please refer to Figure 13 and Figure 14 . After the processing is completed, a specific notch 38 is opened on the conductor 36 of the coaxial connector 35.

[0038] As Figures 2 - 4 shown, a device for grooving the inner conductor of a coaxial connector according to the present invention includes an insert 1. One end of the insert 1 is an entry end, and the entry end of the insert 1 can enter the coaxial connector 35. A cavity 10 for inserting the connection core 37 on the coaxial connector 35 is provided inside the insert 1. A plurality of grooving knives 2 surrounding the insert 1 are installed around the insert 1. The specific number of the grooving knives 2 is not fixed but is determined according to actual needs, that is, according to the number of notches 38 on the conductor 36 of the coaxial connector 35. It should be noted that the number of the grooving knives 2 is at least more than one. The grooving knives 2 are used to cut notches 38 on the conductor 36 of the coaxial connector 35.

[0039] The grooving knives 2 are inclined, and one end of the grooving knives 2 is close to the entry end of the insert 1, which is the end inserted into the coaxial connector 35. The other end of the grooving knives 2 gradually moves away from the insert 1, presenting an extended shape from the entry end of the insert 1 to the other end.

[0040] More specifically, the distance between one end of the grooving knife 2 close to the insert 1 and the insert 1 is less than the inner diameter of the conductor 36 on the coaxial connector 35, so that when the entry end of the insert 1 is inserted into the coaxial connector 35, one end of the grooving knife 2 close to the entry end of the insert 1 can smoothly enter the inside of the conductor 36.

[0041] The distance between the other end of the grooving knife 2 away from the insert 1 and the insert 1 is greater than the outer diameter of the conductor 36 on the coaxial connector 35. When operating to cut notches 38 on the conductor 36, the grooving knives 2 can form enough cutting space on the outer periphery of the conductor 36 to ensure grooving of the conductor 36.

[0042] When cutting notches 38 on the conductor 36 of the coaxial connector 35, the insert 1 is driven to enter the coaxial connector 35. The movement of the coaxial connector 35 drives the grooving knives 2 to move synchronously, and the grooving knives 2 cut notches 38 on the conductor 36 of the coaxial connector 35 from the inside to the outside.

[0043] The present invention provides three connection methods for the grooving tool 2 and the insert 1, and the specific connection methods are as follows:

[0044] For the first connection method, the grooving tool 2 and the insert 1 adopt a fixed connection method. The grooving tool 2 and the insert 1 can be fixedly connected by means such as welding or integral molding. The advantages of this connection method are stable connection, simple structure, and low manufacturing cost.

[0045] For the second connection method, the grooving tool 2 and the insert 1 adopt a detachable connection method, such as using traditional connection means such as bolts, nuts or buckles. The advantage of this connection method is to improve the convenience and economy of use. When the grooving tool 2 is damaged, only the damaged grooving tool 2 needs to be replaced separately, without replacing other intact grooving tools 2, effectively reducing the later use cost.

[0046] For the third connection method, as Figures 2 - 4 shown, a resisting block 3 is slidably installed at the entering end of the insert 1. The resisting block 3 is sleeved outside the insert 1. The resisting block 3 can move up and down along the outer wall of the insert 1. The bottom end of the resisting block 3 is lower than the inserting end of the insert 1. The resisting block 3 is arranged as a hollow cylinder, however, resisting blocks 3 of any shape and structure can be applied in the present invention.

[0047] Both ends of the grooving tool 2 are provided with connecting shafts 4. The connecting shafts 4 extend straightly towards both ends. The resisting block 3 is provided with several connecting blocks 7. The connecting blocks 7 are connected to the connecting shafts 4. Through the cooperation of the connecting shafts 4 and the connecting blocks 7, the resisting block 3 is hinged to one end of the grooving tool 2. This hinged method not only ensures the flexible rotation of the grooving tool 2 within a certain range, but also ensures the stability of the connection.

[0048] An installation arm 5 is fixedly arranged on the outer wall of the insert 1. A guiding groove 6 is formed on the installation arm 5. The guiding groove 6 is adapted to the connecting shaft 4. The connecting shaft 4 is installed inside the guiding groove 6. The connecting shaft 4 moves along the direction of the guiding groove 6 to guide the other end of the grooving tool 2. The guiding groove 6 provides precise guidance for the movement track of the grooving tool 2, so that the grooving tool 2 maintains a stable and accurate position and angle.

[0049] When the insert 1 enters the coaxial connector 35, since the bottom end of the abutting block 3 is lower than the insertion end of the insert 1, the bottom end of the abutting block 3 contacts the inside of the coaxial connector 35 first. When the insert 1 continues to enter the coaxial connector 35, the abutting block 3 moves upward relative to the insert 1 and cooperates with the guiding groove 6 to guide the connecting shaft 4, increasing the inclination angle of the grooving cutter 2 that is cutting. That is to say, the distance between the end of the grooving cutter 2 farther from the connecting member 34 and the connecting member 34 increases significantly. Due to the increase in the inclination angle of the grooving cutter 2, the grooving cutter 2 forms a downward chopping action, effectively improving the efficiency of the grooving cutter 2 to cut the notch 38 on the conductor 36 of the coaxial connector 35.

[0050] As Figure 4 shown, a ring of flange body one 11 is formed on the outer wall of the insert 1 near the bottom end, and a ring of flange body two 12 is correspondingly arranged on the inner wall of the sleeve 13. The structural dimensions of the flange body one 11 and the flange body two 12 are strictly calculated and designed, and their structures are mutually adapted. When the sleeve 13 moves up and down along the insert 1, the flange body one 11 and the flange body two 12 cooperate with each other to play a limiting role. During the downward movement of the sleeve 13, when the flange body one 11 contacts the flange body two 12, the two abut against each other to limit the further downward displacement of the sleeve 13, setting a lower limit for the downward movement of the sleeve 13. Effectively preventing the sleeve 13 from detaching from the insert 1 during the movement process.

[0051] On the basis of this connection method, a fixing member 8 is fixedly arranged on the outer wall of the insert 1. A spring 9 is arranged between the fixing member 8 and the abutting block 3, and the spring 9 is sleeved on the outside of the insert 1. When the insert 1 exits from the coaxial connector 35, the spring 9 can rely on its own elastic potential energy to provide elastic force for the abutting block 3 to return to the initial position. If the entrance end of the insert 1 is set downward, the spring 9 can also not be installed, because when the insert 1 exits from the coaxial connector 35, the abutting block 3 will fall naturally under the action of gravity. However, installing the spring 9 has significant advantages. The elastic buffering effect of the spring 9 enables the grooving cutter 2 to move more smoothly during the movement process. Whether during the process of cutting the notch 38 or in each link where the abutting block 3 and the grooving cutter 2 move in coordination, the spring 9 can effectively reduce the vibration and shaking of the grooving cutter 2, ensuring that the movement trajectory of the grooving cutter 2 is more accurate and stable.

[0052] The above-mentioned insert 1 can be directly connected to the driving device 23. This connection method simplifies the power transmission path, and the driving device 23 can use devices such as electric telescopic rods, hydraulic cylinders, and pneumatic telescopic rods that can drive the displacement of the insert 1.

[0053] The electric telescopic rod has become a common choice due to its precise displacement control, efficient power output, and ease of automation control. It drives the screw-nut mechanism through a motor, converting rotational motion into linear motion to achieve precise displacement drive for the insert 1.

[0054] The hydraulic cylinder, on the other hand, has strong thrust and good load-bearing capacity. Under the action of the hydraulic system, high-pressure hydraulic fluid pushes the piston to move inside the cylinder barrel, thereby driving the insert 1 to generate displacement. The hydraulic cylinder is suitable for occasions that require large driving forces and can ensure that the insert 1 operates stably and reliably under heavy load conditions.

[0055] The pneumatic telescopic rod uses compressed air as the power source and has characteristics such as fast response speed, simple structure, and convenient maintenance. By controlling the inlet and outlet of compressed air, rapid telescopic movement of the insert 1 can be achieved, which is particularly suitable for working scenarios with high requirements for action speed.

[0056] In summary, whether it is an electric telescopic rod, a hydraulic cylinder, or a pneumatic telescopic rod, these driving devices can provide reliable displacement drive for the insert 1. Users can flexibly select the most suitable driving device 23 according to the actual working conditions and requirements to ensure the operation of the equipment.

[0057] As Figures 5 - 7 shown, in order to further improve the processing efficiency of the coaxial connector 35, after cutting the notch 38 on the conductor 36 of the coaxial connector 35, the outer wall of the conductor 36 on the coaxial connector 35 can be directly polished. A sleeve 13 with a hollow interior is fixedly arranged on the insert 1, and a polishing assembly for polishing the outer wall of the conductor 36 of the coaxial connector 35 is installed inside the sleeve 13. The polishing assembly includes a mounting frame 14 and a polishing disc 39 detachably mounted on the mounting frame 14 to facilitate the replacement of the polishing disc 39.

[0058] In order to achieve the polishing function, the end of the connecting piece 34 is no longer directly connected to the driving device 23 at this time. Instead, a driving shaft 28 is coaxially connected to the insert 1. This change in the connection method is based on a comprehensive consideration of the overall processing flow and function realization. By adjusting the connection structure, a reasonable spatial layout can be provided for the integration and realization of the subsequent polishing function, ensuring that after the notch 38 process is completed, the equipment can smoothly and efficiently transition to the polishing process.

[0059] For further detailed description, the insert 1 is connected to the motor 26 through the driving shaft 28, and the rotating ends of the driving shaft 28 and the motor 26 are coaxially connected. When the grooving tool 2 finishes cutting the notch 38, as Figure 10 and 12As shown, the insert 1 is withdrawn a certain distance from within the coaxial connector 35. At this time, the grooving tool 2 completely withdraws from the notch 38, and the grinding assembly is located at the notch 38 on the outer wall of the conductor 36. The motor 26 is started, and the motor 26 transmits power through the drive shaft 28 to drive the insert 1 and the sleeve 13 to rotate simultaneously. The grinding assembly on the sleeve 13 also rotates accordingly to grind the outer wall of the conductor 36.

[0060] In order to enable the grinding assembly to grind conductors 36 with different outer diameters, the mounting bracket 14 and the sleeve 13 are connected by a drive rod 15. The drive rod 15 is slidably connected to the sleeve 13. A through groove 16 for the drive rod 15 to slide is provided on the sleeve 13. The drive rod 15 is used to drive the grinding assembly to move to control the distance between the grinding assembly and the outer wall of the conductor 36 on the coaxial connector 35.

[0061] The movement of the drive rod 15 can be controlled by a telescopic device 17. The telescopic device 17 can use an electric telescopic rod, a hydraulic cylinder, a pneumatic telescopic rod, etc., which can make the drive rod 15 move. Users can flexibly select the most suitable telescopic device 17 according to the actual working conditions and requirements, and its characteristics and advantages are referred to above. The telescopic device 17 is installed on the sleeve 13. The present invention provides two installation methods of the telescopic device 17 for users to choose:

[0062] For the first installation method, the length direction of the telescopic device 17 can be installed along the radial direction of the sleeve 13. The telescopic end of the telescopic device 17 is directly connected to the drive rod 15. The length direction of the telescopic device 17 is parallel to the direction of the drive rod 15. The advantage of this installation method is that the connection structure is simple and the connection is more convenient. However, the length of the telescopic device 17 is longer, and when the sleeve 13 rotates, the telescopic device 17 requires a larger movement space to rotate.

[0063] For the second installation method, as Figures 6 - 7 shown, the telescopic device 17 can be installed along the outer wall of the sleeve 13 and parallel to the axial direction of the sleeve 13. At this time, the telescopic end of the telescopic device 17 cannot be directly connected to the drive rod 15. A drive frame 18 is installed at the telescopic end of the telescopic device 17. An inclined chute 19 is provided on the drive frame 18. A guide shaft 40 is provided on the drive rod 15. The guide shaft 40 is installed in the chute 19. The chute 19 guides the guide shaft 40. The telescopic device 17 expands and contracts to control the movement of the drive frame 18. The guide groove 6 changes the direction of the expansion and contraction of the telescopic device 17 to the radial direction to drive the guide shaft 40 to move and at the same time make the drive rod 15 move. The advantage of this installation method is that when the sleeve 13 rotates, the telescopic device 17 requires a smaller movement space to rotate. However, the connection method is relatively complex.

[0064] A connecting groove 20 is formed on the side wall of the driving frame 18. At the same time, a guiding rail 21 is provided on the outer wall of the sleeve 13. The guiding rail 21 is precisely inserted into the connecting groove 20, and the two are closely matched. When the telescopic device 17 drives the driving frame 18 to move, the connecting groove 20 can slide smoothly along the length direction of the guiding rail 21. This effectively avoids unstable situations such as shaking and deviation that may occur during the movement of the driving frame 18, and greatly improves the stability of the telescopic movement of the driving frame 18.

[0065] The user can select a suitable installation method for the telescopic device 17 according to their own usage needs or the needs of the working environment.

[0066] As Figures 8 - 11 shown, to ensure the smooth movement of the motor 26, the motor 26 is installed on the lifting platform 25. The lifting platform 25 is in sliding fit with the support rod 24 fixed on the base 22. When the lifting platform 25 slides up and down along the length direction of the support rod 24, the motor 26 rises and falls smoothly. This effectively avoids the shaking and deviation of the motor 26 during the lifting process, making the movement of the motor 26 and the grooving tool 2 more stable.

[0067] To control the lifting of the lifting platform 25, the driving device 23 described in the previous text is used. One end of the driving device 23 is connected to the lifting platform 25, and the other end is connected to the base 22. By operating the driving device 23, the lifting action of the lifting platform 25 is precisely controlled, and thus the smooth lifting operation of the motor 26 and the grooving tool 2 is achieved. During operation, simply start the driving device 23 to easily achieve the lifting action of the motor 26 and the grooving tool 2.

[0068] As Figures 10 - 12 shown, a through hole 30 communicating with the internal cavity 10 of the insert 1 is formed at the top of the insert 1. The setting of this through hole 30 provides a passage for the travel switch 29 described in detail later. A travel switch 29 is installed at the end of the drive shaft 28. The travel switch 29 can smoothly enter the cavity 10 of the insert 1 through the through hole 30 at the top of the insert 1. The function of the travel switch 29 is to detect whether the connection core 37 on the coaxial connector 35 is in place. During the operation of the equipment, the accurate positioning of the connection core 37 is an important prerequisite for the normal operation of the equipment. When the position of the connection core 37 changes, the travel switch 29 can timely feedback the detection signal according to whether the connection core 37 triggers the travel switch 29. Particularly importantly, the travel switch 29 is closely related to the driving device 23, the telescopic device 17, and the motor 26. The travel switch 29 controls the actions of the driving device 23, the telescopic device 17, and the motor 26. Once the travel switch 29 detects a change in the in-place situation of the connection core 37 on the coaxial connector 35, it will quickly send control instructions to the driving device 23, the telescopic device 17, and the motor 26, thereby achieving the control of the actions of these three devices.

[0069] As Figures 8 - 11 shown, during the operation of the device, when the motor 26 drives the sleeve 13 to rotate, the telescopic device 17 will also rotate synchronously. To ensure real-time control of the telescopic device 17, a rotary joint 27 is installed on the lifting platform 25. The rotary joint 27 not only ensures that the telescopic device 17 rotates with the sleeve 13, but also provides a basis for physical connection and signal transmission for real-time control, enabling both the flexible rotation of the telescopic device 17 and the control of the telescopic device 17.

[0070] As Figure 10 shown, the rotary joint 27 is composed of a fixed part and a rotating part. The fixed part is connected to the lifting platform 25, and the rotary joint 27 is coaxially installed with the drive shaft 28. A hole for the drive shaft 28 to pass through is provided along the central axis in the middle of the rotary joint 27. An input end 31 is provided on the fixed part for accessing external control signals or power. An input member 33 is equipped on the input end 31 to facilitate connection with external devices. The rotating part is provided with an output end 32, and the output end 32 is connected to the telescopic device 17 through a connecting member 34 to ensure that signals and power can be effectively transmitted to the telescopic device 17. During the process of the motor 26 driving the sleeve 13 to rotate, causing the telescopic device 17 to rotate synchronously, the fixed part of the rotary joint 27 can remain stable, while the rotating part can rotate flexibly, so that the telescopic device 17 can not only follow the movement, but also transmit control instructions through the input member 33 and, after being transmitted by the rotary joint 27, realize real-time and precise control of the telescopic device 17.

[0071] According to different control methods, a suitable rotary joint 27 can be selected. For example, when controlling the telescopic device 17 using electrical signals, gas, or liquid, etc., the selected rotary joint 27 needs to be adapted to the control method. For example, when controlling the telescopic device 17 using electrical signals, the rotary joint 27 needs to transmit electrical signals; when controlling the telescopic device 17 using gas, the rotary joint 27 needs to transmit gas; when controlling the telescopic device 17 using liquid, the rotary joint 27 needs to transmit liquid. It can meet the requirements of controlling the telescopic device 17 to act in different ways.

[0072] Similarly, according to different control methods, the input member 33 and the connecting member 34 can be pipelines or cables, etc., to achieve the transmission of different signals or power.

[0073] In summary, the specific operation steps of the device for grooving the inner conductor of the coaxial connector are as follows when in use:

[0074] 1. Fixing the coaxial connector: Place the coaxial connector 35 to be processed at the designated processing position. It can be fixed by hand or by using a clamp to ensure that the coaxial connector 35 will not be deflected, tipped over or rotated during the processing.

[0075] 2. Conductor slotting: During the slotting process of the conductor 36 on the coaxial connector 35, the drive device 23 provides power for the insert 1 to enter the coaxial connector 35. The drive device 23 accurately drives the insert 1 so that it can stably move into the inside of the coaxial connector 35. When the insert 1 moves, it will synchronously drive the slotting knife 2 to move together. The slotting knife 2 cuts from the inside to the outside of the conductor 36 and cuts a slot 38 on the conductor 36. This cutting direction from the inside to the outside has significant advantages. During the cutting process, foreign matter such as burrs, residual materials and metal debris will inevitably be generated. Since the cutting direction is from the inside to the outside, these foreign matter will naturally be generated on the outside of the conductor 36. In this way, the subsequent cleaning and polishing of the conductor 36 is greatly facilitated. The staff does not need to go deep into the conductor 36 to deal with these foreign matter, and can easily complete the cleaning on the outside of the conductor 36, which not only improves the work efficiency but also reduces the difficulty of operation. When the slot 38 is opened according to the predetermined requirements, the drive device 23 will drive the insert 1 to move and withdraw the insert 1 from the coaxial connector 35 in a smooth and precise manner. At this point, the entire process of slotting the conductor 36 is completed, and the coaxial connector 35 is ready to enter the next processing stage.

[0076] 3. Conductor grinding: After completing the grooving process of the conductor 36, the insert 1 needs to be withdrawn a certain distance. To make the grooving knife 2 completely withdraw from the notch 38, it is necessary to ensure that the grinding component is exactly located on the outer wall of the conductor 36 and is precisely aligned with the position of the notch 38 that has just been processed. When the insert 1 is accurately withdrawn to the appropriate position, the motor 26 is started. The motor 26 provides power for the entire grinding process. The drive shaft 28 of the motor 26 is connected to the sleeve 13. As the motor 26 is started, the rotational power is transmitted to the sleeve 13, driving the sleeve 13 to start rotating. Since the grinding component is tightly fitted with the sleeve 13, the rotation of the sleeve 13 will further drive the grinding component to rotate at high speed. At this time, the high-speed rotating grinding component contacts the outer wall of the conductor 36 and begins to grind the outer wall of the conductor 36 on the coaxial connector 35, especially the area where the notch 38 is located. By grinding, burrs, excess material, metal debris and other foreign matter generated on the outer wall of the conductor 36 during the cutting process can be effectively removed, making the outer wall of the conductor 36 smoother, thereby improving the overall quality of the coaxial connector 35.

[0077] By operating according to the above steps, a series of processing procedures such as grooving and polishing the conductor 36 of the coaxial connector 35 can be completed. This process is coherent, smooth, convenient to operate, and can effectively improve the processing efficiency.
