Description

Technical Field

[0001] The invention relates to the technical field of coaxial connectors, in particular to a device for processing grooves in inner conductors of coaxial connectors. Background Art

[0002] Coaxial connectors are parts used to connect the ends of two shafts to ensure that the center lines of the two shafts are on the same axis. They are generally used to connect the driving shaft and the driven shaft to transmit the rotational motion of the driving shaft to the driven shaft. In today's electronic equipment manufacturing field, coaxial connectors are a common electronic component and are widely used in various electronic products, playing a key role in signal transmission.

[0003] The most common coaxial connectors in daily life, such as Figure 1 As shown in the figure, there is usually a connecting core in the middle, surrounded by a hollow cylindrical conductor. Fig.13 and 14 As shown, a notch is provided on the conductor wall of the coaxial connector. However, when the conductor of such a coaxial connector is notched, the existing processing method has the following shortcomings: In the prior art, the conductor is slotted by using slotting tools such as cutting tools or punching tools, and the slotting is performed from the outside of the conductor to the inside of the conductor, or the slotting is performed perpendicular to the conductor from top to bottom along the axial direction of the conductor (at the moment when the slotting tool contacts the conductor wall, the material at the conductor is subjected to concentrated shear force, so that this part of the material is separated from the conductor body. The separated material, that is, the burrs, residual materials, metal debris and other foreign matter generated, part of it will go to the outside of the conductor along the slot; while the other part will go to the inside of the conductor along the slot). During the processing of the above two slotting methods, it is very easy to cause the burrs, residual materials and metal debris generated during slotting to enter the inside of the conductor. Due to the small internal space of the conductor and the closed circular structure, it is difficult to clean these foreign matters on the inside of the conductor, which consumes a lot of manpower and time costs. In addition, it is not easy to effectively grind the inner wall of the conductor, which seriously affects the production efficiency of the coaxial connector and increases the defective rate of the product, which needs to be solved in actual production. Summary of the invention

[0004] In view of the shortcomings of the prior art, the present invention provides a device for processing grooves in the inner conductor of a coaxial connector, which solves the problem of foreign matter entering the inner side of the conductor during the traditional groove processing, and the subsequent inconvenience in cleaning and polishing.

[0005] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a device for processing grooves in conductors of a coaxial connector, comprising an insert, one end of which can enter the coaxial connector, and a plurality of grooving knives are installed around the insert, the grooving knives are arranged at an angle, and one end of the grooving knives is close to the entry end of the insert, and the other end of the grooving knives is away from the insert; the insert is driven into the coaxial connector, driving the grooving knives to move synchronously, and the grooving knives groove the conductor on the coaxial connector from the inside to the outside.

[0006] Furthermore, a stop block is slidably mounted on the entry end of the insert, a mounting arm is fixedly mounted on the outer wall of the insert, the stop block is hinged to one end of the grooving knife, and a guide groove is provided on the mounting arm for guiding the other end of the grooving knife.

[0007] Furthermore, a fixing piece is fixedly provided on the outer wall of the insert, and a spring is provided between the fixing piece and the stop block.

[0008] Furthermore, the bottom end of the stop block is lower than the entry end of the insert.

[0009] Furthermore, a cavity is provided inside the insert for inserting a connecting core on the coaxial connector.

[0010] Furthermore, a sleeve with a hollow interior is fixedly provided on the insert, and a polishing component for polishing the outer wall of the conductor of the coaxial connector is installed inside the sleeve.

[0011] Furthermore, the grinding assembly includes a mounting frame and a grinding sheet detachably mounted on the mounting frame.

[0012] Furthermore, the mounting frame and the sleeve are connected by a driving rod, and the driving rod and the sleeve are slidably connected. The sleeve is provided with a through groove for the driving rod to slide. The driving rod drives the grinding assembly to move to control the distance between the grinding assembly and the outer wall of the conductor on the coaxial connector.

[0013] Furthermore, a driving shaft is coaxially connected to the insert, the insert is connected to the motor via the driving shaft, and the driving shaft and the rotating end of the motor are coaxially connected.

[0014] Furthermore, it also includes a driving device for driving the insertion member to move.

[0015] Compared with the prior art, the present invention provides a device for processing grooves in inner conductors of coaxial connectors, which has the following beneficial effects: The invention relates to a device for processing grooves of inner conductors of a coaxial connector. Through the setting of an insert, a plurality of groove cutting knives are installed around the insert. The groove cutting knives are arranged obliquely, and one end of the groove cutting knives is close to the entry end of the insert, and the other end of the groove cutting knives is far away from the insert. When grooves are cut, the insert is driven into the coaxial connector to drive the groove cutting knives to move synchronously, so that the groove cutting knives groove the conductor from the inside to the outside. Compared with the traditional groove cutting method (from the outside to the inside or from the top to the bottom), the device effectively avoids the problem of foreign matter such as burrs, residual materials and metal debris entering the inner side of the conductor in the traditional processing, and fundamentally eliminates the problem of inconvenience in subsequent processing caused by foreign matter entering the inner side of the conductor.

[0016] 1. Easy to clean and polish: Foreign matter produced by cutting is located on the outside of the conductor. Compared with the traditional outside-in or axial cutting that causes foreign matter to fall into the inside of the conductor, the operation space for cleaning and polishing is wider and the operation difficulty is greatly reduced. No complicated internal cleaning tools and cumbersome procedures are required, which greatly improves the efficiency of cleaning and polishing and saves a lot of time and labor costs.

[0017] 2. Improve processing efficiency and product quality: The fast and convenient cleaning and polishing process shortens the entire processing cycle and significantly improves processing efficiency. At the same time, it effectively prevents foreign matter from entering the conductor and can polish the conductor well, which improves product quality and thus increases the product qualification rate.

DETAILED DESCRIPTION

[0020] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0021] The existing coaxial connector 35 has a structural design such as Figure 1 As shown. A metal connecting core 37 is arranged in the middle of the coaxial connector 35, and a conductor 36 in the shape of a hollow cylinder is arranged around the connecting core 37. The conductor 36 plays a key role in the conduction of the signal transmission and can also provide effective physical support.

[0022] In the manufacturing process of the coaxial connector 35, the processing of its conductor 36 is an important step. From before processing to after processing, the conductor 36 undergoes significant changes. For details, please refer to Fig.13 and Fig.14 After processing, a specific notch 38 is formed on the conductor 36 of the coaxial connector 35 .

[0023] like Figure 2-4 As shown, a device for processing grooves in the inner conductor of a coaxial connector of the present invention comprises an insert 1, one end of the insert 1 being an entry end, the entry end of the insert 1 being able to enter into the coaxial connector 35, the interior of the insert 1 being provided with a cavity 10 for inserting a connecting core 37 on the coaxial connector 35, and a plurality of grooving knives 2 surrounding the insert 1 being installed around the insert 1. The specific number of grooving knives 2 is not fixed, but is determined according to actual needs, that is, it is determined according to the number of notches 38 on the conductor 36 of the coaxial connector 35. It should be noted that the number of grooving knives 2 must be at least one. The grooving knives 2 are used to make notches 38 on the conductor 36 on the coaxial connector 35.

[0024] The grooving knife 2 is arranged at an angle, and one end of the grooving knife 2 is close to the entry end of the insert 1, which is the end inserted into the coaxial connector 35, and the other end of the grooving knife 2 gradually moves away from the insert 1, and the overall grooving knife 2 is arranged in an extended shape from the entry end of the insert 1 to the other end.

[0025] To further explain in detail, the distance between the end of the grooving knife 2 close to the insert 1 and the insert 1 is smaller 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, the end of the grooving knife 2 close to the entry end of the insert 1 can smoothly enter the interior of the conductor 36.

[0026] The distance between the 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 the groove 38 is cut into the conductor 36, the grooving knife 2 can form sufficient cutting space on the periphery of the conductor 36 to ensure that the conductor 36 is grooved.

[0027] When cutting the notch 38 on the conductor 36 on the coaxial connector 35 , the insert 1 is driven into the coaxial connector 35 , and the movement of the coaxial connector 35 drives the notch cutter 2 to move synchronously, and the notch cutter 2 cuts the notch 38 on the conductor 36 on the coaxial connector 35 from the inside to the outside.

[0028] The present invention provides three connection modes of the grooving cutter 2 and the insert 1, and the specific connection modes are as follows: In the first connection method, the grooving knife 2 and the insert 1 are fixedly connected. The grooving knife 2 and the insert 1 can be fixedly connected by welding or integral molding. The advantages of this connection method are stable connection, simple structure and low manufacturing cost.

[0029] In the second connection mode, the grooving knife 2 and the insert 1 are detachably connected, such as by conventional bolts, nuts or buckles. The advantages of this connection mode are that it improves the convenience and economy of use. When the grooving knife 2 is damaged, only the damaged grooving knife 2 needs to be replaced, and other intact grooving knives 2 do not need to be replaced, which effectively reduces the cost of later use.

[0030] The third connection method, such as Figure 2-4 As shown, a stop block 3 is slidably installed at the entry end of the insert 1. The stop block 3 is sleeved on the outside of the insert 1. The stop block 3 can move up and down along the outer wall of the insert 1. The bottom end of the stop block 3 is lower than the insertion end of the insert 1. The stop block 3 is set as a hollow cylinder inside. However, the stop block 3 of any shape and structure can be applied to the present invention.

[0031] Both ends of the grooving knife 2 are provided with connecting shafts 4, which extend straightly to both ends. The stop block 3 is provided with a plurality of connecting blocks 7, which are connected to the connecting shafts 4. Through the cooperation between the connecting shafts 4 and the connecting blocks 7, the stop block 3 is hinged to one end of the grooving knife 2. This hinged connection method not only ensures the flexible rotation of the grooving knife 2 within a certain range, but also ensures the stability of the connection.

[0032] A mounting arm 5 is fixedly provided on the outer wall of the insert 1, and a guide groove 6 is provided on the mounting arm 5. The guide groove 6 is adapted to the connecting shaft 4. The connecting shaft 4 is installed inside the guide groove 6. The connecting shaft 4 moves along the direction of the guide groove 6 to guide the other end of the grooving knife 2. The guide groove 6 provides precise guidance for the movement trajectory of the grooving knife 2, so that the grooving knife 2 maintains a stable and accurate position and angle.

[0033] When the insert 1 enters the coaxial connector 35, since the bottom end of the stop block 3 is lower than the insertion end of the insert 1, the bottom end of the stop block 3 first contacts the inside of the coaxial connector 35. When the insert 1 continues to enter the coaxial connector 35, the stop block 3 moves upward relative to the insert 1, and cooperates with the guide groove 6 to guide the connecting shaft 4, so that the inclination angle of the grooving knife 2 that is cutting is increased, that is, the distance between the end of the grooving knife 2 that is farther from the connecting part 34 and the connecting part 34 is significantly increased. Due to the increase in the inclination angle of the grooving knife 2, the grooving knife 2 forms a downward chopping action, which effectively improves the efficiency of the grooving knife 2 in cutting the notch 38 of the conductor 36 on the coaxial connector 35.

[0034] like Figure 4As shown, a circle of flange body 11 is formed near the bottom end of the outer wall of the insert 1, and a circle of flange body 2 12 is correspondingly arranged on the inner wall of the sleeve 13. The structural dimensions of flange body 11 and flange body 2 12 have been strictly calculated and designed, and the structures of the two are adapted to each other. When the sleeve 13 moves up and down along the insert 1, flange body 11 and flange body 2 12 cooperate with each other to play a role of limiting. During the downward movement of the sleeve 13, when flange body 11 and flange body 2 12 come into contact, the two offset each other to limit the continued downward displacement of the sleeve 13, and set a lower limit for the downward movement of the sleeve 13. It effectively prevents the sleeve 13 from being separated from the insert 1 during the movement.

[0035] On the basis of this connection method, a fixing member 8 is fixedly provided on the outer wall of the insert 1, a spring 9 is provided between the fixing member 8 and the stopper 3, and the spring 9 is sleeved on the outside of the insert 1. When the insert 1 is withdrawn from the coaxial connector 35, the spring 9 can provide elastic force for the stopper 3 to return to its initial position by virtue of its own elastic potential energy. If the entry end of the insert 1 is set downward, the spring 9 may not be installed, because when the insert 1 is withdrawn from the coaxial connector 35, the stopper 3 will naturally fall under the action of gravity. However, installing the spring 9 has significant advantages. The elastic buffering effect of the spring 9 allows the grooving knife 2 to be more stable during movement. Whether in the process of cutting the notch 38 or in each link of the coordinated movement of the stopper 3 and the grooving knife 2, the spring 9 can effectively reduce the vibration and shaking of the grooving knife 2, ensuring that the movement trajectory of the grooving knife 2 is more accurate and stable.

[0036] The above-mentioned insert 1 can be directly connected to the driving device 23. This connection method simplifies the power transmission path. The driving device 23 can use an electric telescopic rod, a hydraulic cylinder, a pneumatic telescopic rod, etc. to drive the displacement of the insert 1.

[0037] The electric telescopic rod has become a common choice due to its precise displacement control, efficient power output and easy automation control. It converts rotary motion into linear motion through a motor-driven screw nut mechanism, thereby achieving precise displacement drive of the insert 1.

[0038] The hydraulic cylinder has strong thrust and good load capacity. Under the action of the hydraulic system, the high-pressure oil pushes the piston to move in the cylinder, thereby driving the insert 1 to move. The hydraulic cylinder is suitable for occasions that require a large driving force, and can ensure that the insert 1 can still operate stably and reliably under heavy load conditions.

[0039] The pneumatic telescopic rod uses compressed air as a power source and has the characteristics of fast response speed, simple structure, and convenient maintenance. By controlling the inlet and outlet of compressed air, the insert 1 can be quickly extended and retracted, which is particularly suitable for work scenarios with high requirements for movement speed.

[0040] In short, 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 actual working conditions and needs to ensure the operation of the equipment.

[0041] like Figure 5-7 As shown, in order to further improve the processing efficiency of the coaxial connector 35, after cutting the groove 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, and an internal hollow sleeve 13 is fixedly provided 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 sheet 39 detachably mounted on the mounting frame 14 to facilitate replacement of the polishing sheet 39.

[0042] In order to realize the grinding function, the end of the connecting member 34 is no longer directly connected to the driving device 23, but the driving shaft 28 is coaxially connected to the insert 1. This change in the connection method is based on 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 grinding function, ensuring that after completing the notch 38 process, the equipment can smoothly and efficiently transition to the grinding process.

[0043] To further describe in detail, the insert 1 is connected to the motor 26 via the drive shaft 28, and the rotating ends of the drive shaft 28 and the motor 26 are coaxially connected. Fig.10 and 12 As shown, the insert 1 is withdrawn from the coaxial connector 35 by a certain distance. At this time, the grooving knife 2 is completely withdrawn from the notch 38, and the grinding assembly is located at the notch 38 of 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 at the same time. The grinding assembly on the sleeve 13 also rotates to grind the outer wall of the conductor 36.

[0044] In order to enable the grinding assembly to grind conductors 36 with different outer diameters, the mounting frame 14 and the sleeve 13 are connected by a driving rod 15, and the driving rod 15 and the sleeve 13 are slidably connected. A through groove 16 is provided on the sleeve 13 for the driving rod 15 to slide. The grinding assembly is driven to move by the driving rod 15 to control the distance between the grinding assembly and the outer wall of the conductor 36 on the coaxial connector 35.

[0045] The movement of the driving rod 15 can be driven by the telescopic device 17. The telescopic device 17 can use an electric telescopic rod, a hydraulic cylinder, a pneumatic telescopic rod, or other devices that can move the driving rod 15. The user can flexibly select the most suitable telescopic device 17 according to the actual working conditions and needs. The characteristics and advantages thereof refer to the above. The telescopic device 17 is installed on the sleeve 13. The present invention provides two installation methods of the telescopic device 17 for the user to choose: In the first installation mode, the length direction of the telescopic device 17 can be installed along the radial direction of the sleeve 13, and the telescopic end of the telescopic device 17 is directly connected to the driving rod 15, and the length direction of the telescopic device 17 is parallel to the direction of the driving rod 15. The advantages of this installation mode are simple connection structure and more convenient connection. However, the length of the telescopic device 17 is relatively long, and when the sleeve 13 rotates, the telescopic device 17 needs a larger movement space to rotate.

[0046] The second installation method, such as Figure 6-7 As 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. The telescopic end of the telescopic device 17 is installed with a drive frame 18, and an inclined slide groove 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 slide groove 19. The slide groove 19 guides the guide shaft 40. The telescopic device 17 controls the movement of the drive frame 18. The guide groove 6 changes the direction of the telescopic device 17 to a radial direction to drive the guide shaft 40 to move, and at the same time, the drive rod 15 moves. The advantage of this installation method is that when the sleeve 13 rotates, the telescopic device 17 needs less movement space to rotate. However, the connection method is more complicated.

[0047] A connection groove 20 is provided on the side wall of the driving frame 18, and a guide rail 21 is provided on the outer wall of the sleeve 13. The guide rail 21 is precisely embedded in the connection groove 20, and the two are closely matched. When the telescopic device 17 drives the driving frame 18 to move, the connection groove 20 can slide smoothly along the length direction of the guide rail 21. This effectively avoids the unstable conditions such as shaking and offset that may occur in the driving frame 18 during the movement, and greatly improves the stability of the driving frame 18 during telescopic movement.

[0048] The user can select a suitable installation method for the telescopic device 17 according to his / her own use needs or the needs of the working environment.

[0049] like Figure 8-11As shown, in order to ensure the smooth movement of the motor 26, the motor 26 is installed on the lifting platform 25. The lifting platform 25 is slidably matched 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 is lifted and lowered smoothly. The shaking and deviation of the motor 26 during the lifting process are effectively avoided, making the movement of the motor 26 and the grooving knife 2 more stable.

[0050] The driving device 23 described above is used to control the lifting of the lifting platform 25. One end of the driving device 23 is connected to the lifting platform 25, and the other end is connected to the base 22. Through the operation of the driving device 23, the lifting action of the lifting platform 25 is accurately controlled, thereby realizing the smooth lifting operation of the motor 26 and the grooving knife 2. During operation, the lifting action of the motor 26 and the grooving knife 2 can be easily realized by simply starting the driving device 23.

[0051] like Figure 10-12 As shown, a through hole 30 is provided at the top of the insert 1, which is connected to the internal cavity 10 of the insert 1. The setting of the 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 connecting core 37 on the coaxial connector 35 is in place. During the operation of the equipment, the accurate placement of the connecting core 37 is an important prerequisite for the normal operation of the equipment. When the position of the connecting core 37 changes, the travel switch 29 can trigger the travel switch 29 according to whether the connecting core 37 triggers the travel switch 29, and the detection signal is fed back in time. It is particularly important that the travel switch 29 is closely related to the drive device 23, the telescopic device 17 and the motor 26, and the travel switch 29 controls the action of the drive device 23, the telescopic device 17 and the motor 26. Once the travel switch 29 detects a change in the position of the connecting core 37 on the coaxial connector 35, it will quickly send control instructions to the drive device 23, the telescopic device 17 and the motor 26, thereby controlling the actions of the three devices.

[0052] like Figure 8-11 As shown, during the operation of the equipment, when the motor 26 drives the sleeve 13 to rotate, the telescopic device 17 will also rotate synchronously. In order to ensure the real-time control of the telescopic device 17, a rotary adapter 27 is installed on the lifting platform 25. The rotary adapter 27 can not only ensure that the telescopic device 17 rotates with the sleeve 13, but also provide a basis for physical connection and signal transmission for real-time control, so as to ensure the flexible rotation of the telescopic device 17 and realize the control of the telescopic device 17.

[0053] like Fig.10As shown, the rotary adapter 27 is composed of a fixed part and a rotating part. The fixed part is connected to the lifting platform 25, and the rotary adapter 27 and the drive shaft 28 are coaxially installed. A hole for the drive shaft 28 to pass through is opened in the middle of the rotary adapter 27 along the central axis. An input end 31 is provided on the fixed part for receiving external control signals or power, and an input member 33 is provided on the input end 31 for convenient connection with external equipment. An output end 32 is provided on the rotating part, and the output end 32 is connected to the telescopic device 17 through a connecting member 34 to ensure that the signal and power can be effectively transmitted to the telescopic device 17. In the process of the motor 26 driving the sleeve 13 to rotate and causing the telescopic device 17 to rotate synchronously, the fixed part of the rotary adapter 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 the control command through the input member 33, and after being transmitted by the rotary adapter 27, the telescopic device 17 can be controlled in real time and accurately.

[0054] According to different control methods, a suitable rotary adapter 27 can be selected. For example, when the telescopic device 17 is controlled by electric signals, gas or liquid, the selected rotary adapter 27 needs to adapt to the control method. For example, when the telescopic device 17 is controlled by electric signals, the rotary adapter 27 needs to transmit the electric signal; when the telescopic device 17 is controlled by gas, the rotary adapter 27 needs to transmit the gas; when the telescopic device 17 is controlled by liquid, the rotary adapter 27 needs to transmit the liquid. It can meet the requirements of controlling the telescopic device 17 in different ways.

[0055] Similarly, depending on the control method, the input component 33 and the connecting component 34 can be pipelines or cables, etc., to achieve the transmission of different signals or powers.

[0056] In summary, the specific operating steps of the coaxial connector inner conductor slotting processing device when in use are as follows: 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.

[0057] 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.

[0058] 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.

[0059] By following the above steps, a series of processing processes such as grooving and grinding the conductor 36 of the coaxial connector 35 can be completed. The process is smooth and easy to operate, which can effectively improve the processing efficiency.
