Conductive structure of ultrasonic spindle

Abstract

This invention discloses a conductive structure for an ultrasonic spindle, comprising a sleeve and a conductive adapter. The sleeve is detachably connected to the front end of the push rod of the ultrasonic spindle, and the conductive adapter is disposed within a through hole in the sleeve. Thus, when the conductive adapter needs maintenance or replacement, only the sleeve needs to be disassembled for individual maintenance or replacement of the conductive adapter, and then the sleeve can be reinstalled onto the push rod. This is not only simple and convenient to operate, but also, since the wire is connected to the conductive head, it is unaffected by the wire and allows for repeated disassembly and assembly, thereby effectively reducing the maintenance cost of the ultrasonic spindle.

Description

Technical Field

[0001] This invention relates to the field of ultrasonic processing technology, and in particular to a conductive structure for an ultrasonic spindle. Background Technology

[0002] Introducing high-frequency vibration machining mechanisms into the machining process can not only improve the surface roughness and machining accuracy of the cutting surface, but also reduce cutting resistance and increase tool life, and is therefore gradually being widely used.

[0003] Existing ultrasonic spindles typically consist of a base, a rotating shaft, and an ultrasonic tool holder. The rotating shaft is mounted within the base and has a sleeve at its lower end. A power connector is located within the sleeve, and its conductive ring is electrically connected to an external power source via a wire. The ultrasonic tool holder has a corresponding sleeve portion with a power plug. The conductive pin of this power plug is electrically connected to an oscillator inside the ultrasonic tool holder via a wire. When the ultrasonic tool holder is mounted on the rotating shaft, the sleeve portion engages with the sleeve, and the power plug is inserted into the power connector. This creates an electrical connection between the conductive ring and the conductive pin, allowing current from the external power source to be transmitted through the conductive ring and conductive pin to the oscillator, driving the tool mounted on the ultrasonic tool holder to vibrate at high frequency. However, this structure has the following drawbacks:

[0004] 1. The power connector is located inside the sleeve hole, making it difficult to disassemble and install, and inconvenient for inspection and replacement;

[0005] 2. The power cord connecting to the external power source is fixed to the conductive ring of the power connector, which means that when disassembling the power connector, the power cord can only be broken, and repeated disassembly and assembly are not possible. Summary of the Invention

[0006] The purpose of this invention is to provide a conductive structure for an ultrasonic spindle that is easy to maintain, convenient to assemble and disassemble, and has stable electrical conductivity.

[0007] To achieve the above objectives, the present invention provides a conductive structure for an ultrasonic spindle, comprising:

[0008] A sleeve, wherein the sleeve is provided with through holes extending through its front and rear ends;

[0009] A conductive adapter is disposed within the through hole. The conductive adapter includes a column and a first conductive medium and a second conductive medium disposed on the column.

[0010] As a preferred embodiment, both the first conductive medium and the second conductive medium are partially embedded inside the column, and the first conductive medium has a first connection position exposed at the rear end of the column, and the second conductive medium has a second connection position exposed at the rear end of the column.

[0011] As a preferred embodiment, the first connection position is in a ring shape and surrounds the periphery of the second connection position.

[0012] As a preferred embodiment, the second connection position is columnar.

[0013] As a preferred embodiment, both the first conductive medium and the second conductive medium are partially embedded inside the column. The front end of the column is provided with a slot. The first conductive medium has a first contact portion exposed on the slot wall, and the second conductive medium has a second contact portion exposed on the slot wall.

[0014] As a preferred embodiment, a sealing ring is provided inside the slot near the opening.

[0015] As a preferred embodiment, the outer wall of the sleeve near its front end is provided with an expansion protrusion.

[0016] As a preferred embodiment, the wall of the through hole is provided with a first connecting thread for connecting the push rod.

[0017] As a preferred embodiment, the wall of the through hole is provided with a second connecting thread, and the conductive adapter is screwed to the wall of the through hole through the second connecting thread.

[0018] As a preferred embodiment, the first conductive medium is embedded inside the column, and the first conductive medium has a fixing part exposed on the side wall of the column. The fixing part is screwed to the wall of the through hole through the second connecting thread.

[0019] This invention provides a conductive structure for an ultrasonic spindle, which has the following advantages compared to the prior art:

[0020] The conductive structure provided by this invention includes a sleeve and a conductive adapter. The sleeve is detachably connected to the front end of the push rod of the ultrasonic spindle, and the conductive adapter is disposed in the through hole of the sleeve. Thus, when the conductive adapter needs maintenance or replacement, only the sleeve needs to be removed, the conductive adapter can be inspected or replaced separately, and then the sleeve can be reinstalled onto the push rod. This is not only simple and convenient to operate, but also, since the wire is connected to the conductive head, it is not affected by the wire and can be repeatedly disassembled and reassembled, thereby effectively reducing the maintenance cost of the ultrasonic spindle.

Detailed Implementation

[0031] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0032] It should be understood that the terms "first," "second," etc., are used in this invention to describe various types of information, but these terms are not limited to them; they are only used to distinguish information of the same type from one another. For example, without departing from the scope of this invention, "first" information may also be referred to as "second" information, and similarly, "second" information may also be referred to as "first" information.

[0033] Additionally, it should be noted that in the description of this invention, the term "upper" includes "inner," "outer," "upper part," "lower part," etc. The terms "front end" and "rear end" refer to the end of the cutting tool closer to the workpiece during use, which is the "front end," and the end farther from the workpiece, which is the "rear end."

[0034] like Figures 1 to 3 As shown, this embodiment of the invention provides an ultrasonic spindle, which mainly includes a cylinder base 1, a rotating shaft 2, a push rod 3, a sleeve 4, a pull claw 5, and an ultrasonic processing assembly.

[0035] like Figures 1 to 5 As shown, the cylinder seat 1 is a stationary component, and the rotating shaft 2 is rotatably inserted inside the cylinder seat 1. The rotating shaft 2 has a cavity inside, and the push rod 3 is located in the cavity and can slide along the cavity. The front end of the rotating shaft 2 has a sleeve hole 201 that communicates with the cavity. The sleeve body 4 has a through hole 401 that passes through its front and rear ends. The wall of the through hole 401 has a first connecting thread 403. The front end of the push rod 3 is screwed to the wall of the through hole 4 through the first connecting thread. In this way, the sleeve body 4 can not only slide with the push rod 3, but also is easy to disassemble. The pull claw 5 is sleeved on the outside of the sleeve body 4. The cavity wall of the cavity has a limiting boss 202 that restricts the sliding of the pull claw 5. The outer wall of the sleeve body 4 near its front end has an expansion protrusion 402. The outside of the pull claw 5 is clamped with an elastic element 23, which is preferably a spring. When the sleeve 4 slides along the cavity towards the rear end of the ultrasonic spindle following the push rod 3, the expansion protrusion 402 opens the pull claw 5; while when the sleeve 4 slides along the cavity towards the front end of the ultrasonic spindle following the push rod 3, the expansion protrusion 402 leaves the pull claw 5, and the pull claw 5 retracts.

[0036] Furthermore, such as Figures 1 to 3As shown, the cylindrical base 1 includes a main housing 101, a front end cover 102, and a rear end cover 103. The main housing 101 is cylindrical, and the rotating shaft 2 passes through the main housing 101. Both the front and rear ends of the main housing 101 have openings. The front end opening has a front bearing seat that is fitted onto the rotating shaft 2 and is connected to the rotating shaft 2 by a front bearing 6. The rear end opening has a rear bearing seat that is fitted onto the rotating shaft 2 and is connected to the rotating shaft 2 by a rear bearing 7. In this way, the rotating shaft 2 can achieve stable rotation. The front end cover 102 is installed on the front bearing seat, and the rear end cover 103 is installed on the rear bearing seat.

[0037] Furthermore, such as Figures 1 to 5 As shown, a wireless transmitting component 8 is provided inside the cylinder base 1, which is located inside the rear end cover 103. A wireless receiving component 9 is provided on the rotating shaft 2, and the wireless receiving component 9 and the wireless transmitting component 8 are arranged opposite each other at a distance. The front end of the push rod 3 is provided with an electrical conductor 10, which includes a first conductor 10a and a second conductor 10b that are insulated from each other. The first conductor 10a is electrically connected to the coil of the wireless receiving component 9 through a first wire 11, and the second conductor 10b is electrically connected to the coil of the wireless receiving component 9 through a second wire 12. A conductive adapter 13 is provided in the through hole 401 of the sleeve 4. The conductive adapter 13 includes a column 13a and a first conductive medium 13b and a second conductive medium 13c provided on the column 13a. The rear end of the column 13a abuts against the front end of the push rod 3. The first conductive medium 13b contacts the first conductor 10a to form an electrical connection, and the second conductive medium 13c contacts the second conductor 10b to form an electrical connection. Based on this, since the conductive head 10 is hidden inside the push rod 3 or between the push rod 3 and the sleeve 4, there is no risk of damage, and no maintenance or replacement is required. As for the conductive adapter 13, although it has a higher risk of damage than the conductive head 10, when the conductive adapter 13 needs to be maintained or replaced, it is only necessary to remove the sleeve 4, maintain or replace the conductive adapter 13 separately, and then install the sleeve 4 back onto the push rod 3. This is not only simple and convenient to operate, but also, since the wire is connected to the conductive head 10, it is not affected by the wire and can be repeatedly disassembled and reassembled, thereby effectively reducing the maintenance cost of the ultrasonic spindle.

[0038] Based on the above structure, by being electrically connected to the power supply, the coil of the wireless transmitting component 8 can generate a stable induced magnetic field. As the rotating shaft 2 rotates relative to the wireless transmitting component 8, the coil of the wireless receiving component 9 can generate an induced current by cutting magnetic field lines. That is, by utilizing the principle of electromagnetic induction, a non-contact electrical connection is formed between the rotating shaft 2 and the cylinder base 1. Then, through the electrical conduction of the first conductor 10a and the second conductor 10b, the first conductive medium 13b and the second conductive medium 13c become charged.

[0039] Compared with existing technologies, non-contact electrical conduction can not only reduce wear, extend the service life of ultrasonic spindles, and improve the cutting effect of high-frequency vibration, but also avoid the momentary circuit break caused by the wobbling of the rotating shaft 2, improve the stability of electrical conduction, and ensure that the vibrator 18 can stably obtain working current. In addition, non-contact electrical conduction can also significantly increase the rotation speed of the rotating shaft 2, so as to meet the requirements of high speed.

[0040] Furthermore, such as Figures 3 to 7 As shown, the first conductor 10a and the second conductor 10b of the conductive head 10 are both made of metal. The second conductor 10b is located inside the first conductor 10a, and the two are connected as one unit by an insulator 10c, which is preferably an insulating plastic. The front end of the first conductor 10a is provided with a first connecting part 1001, and the front end of the second conductor 10b is provided with a second connecting part 1002. The first connecting part 1001 is annular and surrounds the periphery of the second connecting part 1002. Correspondingly, the first conductive medium 13b and the second conductive medium 13c of the conductive adapter 13 are both made of metal, while the column 13a is preferably made of insulating plastic. The first conductive medium 13b and the second conductive medium 13c are partially embedded inside the column by injection molding. The first conductive medium 13b has a first connection position 1301 exposed at the rear end of the column 13a, and the second conductive medium 13c has a second connection position 1302 exposed at the rear end of the column 13a. The first connection position 1301 is annular and surrounds the second connection position 1302. Based on this structure, the first connection portion 1001 is connected to the first connection position 1301, and the second connection portion 1002 is connected to the second connection position 1302. Thus, electrical conductivity is established between the conductive head 10 and the conductive adapter 13.

[0041] Furthermore, such as Figure 3 and Figure 5 As shown, the front end of the push rod 3 is provided with a groove, the electrical conductor 10 is provided in the groove, and the groove wall is provided with an installation thread, and the first conductor 10a is screwed to the groove wall through the installation thread.

[0042] Furthermore, such as Figure 7 As shown, the wall of the through hole 401 is provided with a second connecting thread, and the first conductive medium 13b of the conductive adapter 13 is also provided with a fixing part 1306 exposed on the side wall of the column 13a. The fixing part 1306 is screwed to the wall of the through hole 401 through the second connecting thread.

[0043] Furthermore, such as Figures 5 to 7As shown, the rear end of the first conductor 10a is provided with a first terminal 1004, and the first wire 11 is connected to the first terminal 1004; the rear end of the second conductor 10b is provided with a second terminal 1005, and the second wire 12 is connected to the second terminal 1005. In this embodiment, the first terminal 1004 is annular and surrounds the periphery of the second terminal 1005, and the second terminal 1005 is columnar.

[0044] Optionally, such as Figures 5 to 7 As shown in one specific embodiment of the ultrasonic spindle provided by the present invention, the first connecting position 1301 is inserted into the annular opening of the first connecting portion 1001, the second connecting portion 1002 is provided with a socket 1003, and the second connecting position 1302 is cylindrical and inserted into the socket 1003. In this way, a more stable electrical connection can be formed between the electrical conductive head 10 and the conductive adapter 13. Of course, in other specific embodiments, the first connecting position 1301 can be inserted into the annular opening of the first connecting portion 1001, the second connecting position 1302 is provided with a socket 1003, and the second connecting portion 1002 is cylindrical and inserted into the socket 1003.

[0045] Optionally, such as Figure 4 As shown, in a specific embodiment of the ultrasonic spindle provided by the present invention, a sealing ring 14 is provided between the push rod 3 and the through hole 401 to prevent impurities such as water and steam from entering the through hole 401 and damaging the electrical connection between the electric conductor 10 and the conductive adapter 13.

[0046] Optionally, such as Figures 4 to 5 As shown, in a specific embodiment of the ultrasonic spindle provided by the present invention, the push rod 3 has a through-hole 301 inside, and the through-hole 301 is connected to the groove, through which the first wire 11 and the second wire 12 pass. In order to optimize the arrangement of the first wire 11 and the second wire 12, the through-hole 301 extends through both ends of the push rod 3.

[0047] Optionally, such as Figure 1 As shown, in a specific embodiment of the ultrasonic spindle provided by the present invention, an encoder gear 24 can be provided at the rear end of the rotating shaft 2, and a wireless receiving component 9 is provided on the encoder gear 24.

[0048] like Figure 2 and Figure 8As shown, the ultrasonic processing assembly includes an ultrasonic tool holder and a cutting tool 15. The ultrasonic tool holder further includes a tool holder body 16, an amplitude transformer 17, and a transducer 18. The tool holder body 16 can be sleeved with the rotating shaft 2 through a sleeve hole 201 to rotate with the rotating shaft 2. The front end of the tool holder body 16 is provided with a mounting groove 1601, and the amplitude transformer 17 is fixedly connected to the tool holder body 16 through the mounting groove 1601. The connection method here can be plug-in or screw-in. The transducer 18 is disposed in the mounting groove 1601 and fixed to the amplitude transformer 17. The front end of the amplitude transformer 17 is tapered, and the cutting tool 15 is provided with an assembly groove. The cutting tool 15 is connected to the front end of the amplitude transformer 17 through the assembly groove. Of course, the above connection method can be plug-in or screw-in. It should be noted that the cutter 15 can also be connected to the front end of the amplitude transformer 17 in other ways. For example, the front end of the amplitude transformer 17 is provided with a fixing groove, and the cutter 15 is directly connected to the amplitude transformer 17 through the fixing groove. Alternatively, the cutter 15 can be inserted into or screwed into the fixing groove through a collet sleeved on its outside. In order to improve the connection stability between the cutter 15 and the ultrasonic cutter holder, the ultrasonic cutter holder also includes a sealing nut, which is screwed into the front end of the amplitude transformer 17 and presses the collet.

[0049] Furthermore, such as Figure 3 and Figure 9 As shown, the ultrasonic knife handle also includes an electrical connector 19. The electrical connector 19 includes a rod 19a and a first conductive element 19b and a second conductive element 19c disposed on the rod 19a and insulated from each other. The rod 19a is erected on the knife handle body 16. The first conductive element 19b is electrically connected to the first electrode of the vibrator 18 through a first wire 20, and the second conductive element 19c is electrically connected to the second electrode of the vibrator 18 through a second wire 21.

[0050] It should be noted that, in this embodiment, the electrical connection structure of the ultrasonic spindle includes a push rod 3, an electrical conductor 10, a sleeve 4, and a conductive adapter 13, and the conductive structure of the ultrasonic spindle includes the sleeve 4 and the conductive adapter 13.

[0051] Based on the above structure, when the tool holder body 16 is sleeved with the rotating shaft 2, the rear end of the rod 19a extends into the through hole 401 of the sleeve 4. The first conductive element 19b contacts the first conductive medium 13b to form an electrical connection, and the second conductive element 19c contacts the second conductive medium 13c to form an electrical connection. In this way, an electrical connection is also formed between the ultrasonic tool holder and the rotating shaft 2. The current generated by the coil of the wireless receiving component 9 through cutting magnetic field lines can be transmitted to the vibrator 18, causing it to generate high-frequency vibration, thereby improving the cutting effect of the tool 15.

[0052] Compared with the prior art, the ultrasonic spindle provided by the present invention provides an electrical connector 19 at the rear end of the handle body 16 and a conductive adapter 13 in the sleeve 4, so that the contact electrical connection between the ultrasonic handle and the rotating shaft 2 is located inside the ultrasonic handle or the rotating shaft 2, rather than being exposed in the gap between the ultrasonic handle and the rotating shaft 2, thereby avoiding leakage and eliminating safety hazards.

[0053] Furthermore, such as Figure 3 , Figures 5 to 8 As shown, the rear end of the handle body 16 is provided with a connecting groove 1602, and the rod body 19a is erected in the connecting groove 1602. The groove wall of the connecting groove 1602 is provided with a flange 1603, and the front end of the pull claw 5 is provided with a claw hook 501. When the handle body 16 is sleeved with the rotating shaft 2, there can be two states between the claw hook 501 and the flange 1603: such as Figure 1 As shown, the expansion protrusion 402 of the sleeve 4 opens the pull claw 5, and the claw hook 501 is engaged with the flange 1603 to ensure that the tool holder body 16 will not detach from the rotating shaft 2 when rotating; the expansion protrusion 402 of the sleeve 4 leaves the pull claw 5, the pull claw 5 retracts, and the claw hook 501 disengages from the flange 1603 to realize the tool retraction operation.

[0054] Furthermore, such as Figure 3 , Figures 5 to 8 As shown, the front end of the column 13a of the conductive adapter 13 is provided with a slot 1303 into which the rod 19a of the power connector 19 is inserted. The first conductive medium 13b has a first contact portion 1304 exposed on the groove wall of the slot 1303, and the second conductive medium 13c has a second contact portion 1305 exposed on the groove wall of the slot 1303. For example, the first conductive medium 13b and the second conductive medium 13c are H-shaped spring structures similar to headphone jacks, and the first conductive medium 13b and the second conductive medium 13c are intersected and insulated. Correspondingly, the first conductive element 19b and the second conductive element 19c of the electrical connector 19 are both made of metal, while the rod 19a is preferably made of insulating plastic. The first conductive element 19b and the second conductive element 19c are partially embedded inside by injection molding. The first conductive element 19b has a first contact position 1901 exposed on the outer wall of the rod 19a, and the second conductive element 19c has a second contact position 1902 exposed on the outer wall of the rod 19a. Based on the above structure, when the tool holder body 16 is sleeved with the rotating shaft 2, the rear end of the rod 19a of the electrical connector 19 extends into the through hole 401 of the sleeve 4 and is inserted into the slot 1303 of the column 13a of the conductive adapter 13. Furthermore, the first contact portion 1304 contacts the first contact position 1901, and the second contact portion 1305 contacts the second contact position 1902. Thus, an electrical connection is formed between the conductive adapter 13 and the electrical connector 19.

[0055] Compared with existing technologies, on the one hand, because the conductive adapter 13 concentrates two conductive media onto a single column 13a, and the electrical connector 19 concentrates two conductive elements onto a single rod 19a, the dual alignment between the two conductive media and the two conductive elements is transformed into a single alignment between the column 13a and the rod 19a, greatly reducing the alignment difficulty. Thus, during the connection process between the ultrasonic tool holder and the rotating shaft 2, the conductive adapter 13 and the electrical connector 19 can smoothly form an effective electrical connection with stable electrical conduction, improving the cutting effect of the high-frequency vibration of the ultrasonic spindle. On the other hand, thanks to the support of the column 13a, the conductive media is less prone to wear or bending when forming an electrical connection with the conductive elements. Similarly, thanks to the support of the rod 19a, the conductive elements are also less prone to wear or bending when forming an electrical connection with the conductive media. Therefore, a stable electrical connection can be formed between the conductive adapter 13 and the electrical connector 19, preventing poor contact and effectively extending the service life of the ultrasonic spindle.

[0056] Furthermore, such as Figure 9 As shown, the first conductive element 19b has a first terminal 1903 exposed at the front end of the rod 19a, and the first wire 20 is connected to the first terminal 1903. The second conductive element 19c has a second terminal 1904 exposed at the front end of the rod 19a, and the second wire 21 is connected to the second terminal 1904. In this embodiment, the first terminal 1903 is annular and surrounds the periphery of the second terminal 1904, and the second terminal 1904 is columnar.

[0057] Optionally, such as Figure 3 and Figure 5 As shown, in a specific embodiment of the ultrasonic spindle provided by the present invention, a sealing ring 14 is provided in the slot 1303 near the slot opening. In this way, when the rear end of the rod 19a is inserted into the slot 1303 of the column 13a, the sealing ring 14 can clean water or debris on the rod 19a, thereby improving the reliability of the electrical connection between the conductive medium and the conductive component.

[0058] Optionally, such as Figure 9 As shown, in a specific embodiment of the ultrasonic spindle provided by the present invention, the bottom of the connecting groove 1602 is provided with a recess 1604, and the front end of the rod 19a is fixed in the recess 1604. For example, a collar 22 is sleeved on the front end of the rod 19a, and the collar 22 is screwed or welded to the recess 1604. In addition, in order to prevent water, steam and other impurities from corroding the conductive parts, a sealing ring 14 is also provided between the collar 22 and the rod 19a.

[0059] Optionally, such as Figure 9As shown, in a specific embodiment of the ultrasonic spindle provided by the present invention, a connecting hole 1605 is provided between the recess 1604 and the mounting groove 1601. A first wire 20 passes through the connecting hole 1605 and is electrically connected to a first conductive element 19b, and a second wire 21 passes through the connecting hole 1605 and is electrically connected to a second conductive element 19c. In this embodiment, the first terminal 1903 of the first conductive element 19b and the second terminal 1904 of the second conductive element 19c pass through the connecting hole 1605 and extend into the mounting groove 1601 to facilitate wire connection.

[0060] In summary, the present invention provides a conductive structure for an ultrasonic spindle, which includes a sleeve 4 and a conductive adapter 13. Compared with the prior art, this conductive structure has the advantages of easy maintenance, convenient disassembly and assembly, and stable electrical conductivity.

[0061] The above description is only a preferred embodiment of the present invention. It should be noted that for those skilled in the art, several improvements and substitutions can be made without departing from the technical principles of the present invention, and these improvements and substitutions should also be considered within the scope of protection of the present invention.
