Detailed implementation manners

[0037] For better understanding and implementation, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present application.

[0038] In the description of the present application, it should be noted that the orientation or positional relationship indicated by the terms "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "far", "near", etc. is based on the orientation or positional relationship shown in the drawings, and is only for the convenience of describing the present application and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation to the present application.

[0039] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terms used in the specification of this application are only for the purpose of describing specific embodiments and are not intended to limit this application.

[0040] In the existing design of the turning tool 100, the transducer at the rear end of the ultrasonic turning tool is connected to the ultrasonic generator in a wired manner, resulting in the inability to achieve an automatic tool change process for the ultrasonic turning tool. Although there are also tool changers through a tool turret (electric turntable), due to the wired connection between the ultrasonic turning tool and the ultrasonic generator, the tool change is relatively cumbersome. Different turning tools require dedicated power supply cables, resulting in a complex structure of the turning center and messy wiring harnesses. More specifically, when a wireless power transmission device is used, the wireless power transmitting device and the wireless power receiving device need to be set facing each other to complete power transmission. Therefore, when changing tools, it is necessary to consider the position of the wireless power receiving device on the tool to ensure that the wireless power receiving device and the wireless power transmitting device are still relatively set after the tool change, and at the same time, it will not interfere with the tool change process.

[0041] To solve the problem that the wireless power receiving devices of each tool are relatively set and do not interfere with the tool change process during the tool change process, the present disclosure provides a brand-new turning tool 100, as Figures 1-4 shown. The turning tool 100 includes a wireless receiving device 130, and a tool shank 110 and a tool tip 120 arranged in sequence from the rear to the front. The tool shank 110 includes a housing 111 and a transducer 112 disposed inside the housing 111. The transducer 112 is connected to the tool tip 120. The wireless receiving device 130 is installed on the side of the housing 111, and the wireless receiving device 130 is electrically connected to the transducer 112.

[0042] It should be noted that the side of the housing 111 refers to the side other than the side surface of the housing 111, which is different from the front and the back. Specifically, the housing 111 of this solution is a rectangular-like structure, which has a top surface, a bottom surface, a left side surface, and a right side surface, all of which are side surfaces parallel to the axis B of the housing. The side of the housing 111 refers to its top surface, bottom surface, left side surface, and right side surface. Optionally, as Figure 1 shown, the wireless receiving device 130 is installed on the top surface of the housing 111.

[0043] At the same time, for ease of understanding, Figures 1-4 the third direction X, the fourth direction Y, and the fifth direction Z are marked in

[0044] In the turning tool 100 of the present disclosure, after the transducer 112 receives electrical energy from the wireless receiving device 130, it will generate vibrations and transmit the vibrations to the turning tool head 120, and the turning tool head 120 is used to turn or perform other forms of processing on the article.

[0045] In the above solution, since the wireless receiving device 130 is located on the side of the housing 111 instead of at the rear side or other positions of the housing 111, after the turning tool is installed and the turning tool head is located on the side of the tool disc 500, the bracket for installing the wireless transmitting device bypasses the tool disc 500 from the rear side of the tool disc 500 to extend to the front side of the tool disc 500 (the rear side in this sentence corresponds to Figure 6 the left side in Figure 6 and the front side corresponds to

[0046] For ease of understanding, the present disclosure marks the sixth direction R in Figure 5 and Figure 6 The sixth direction R points from the rear side of the tool disc 500 to the front side of the tool disc 500.

[0047] In some alternative embodiments, as Figure 2 shown, the axis A of the wireless receiving device is perpendicular to the axis B of the housing. Among them, the orientation of the signal receiving surface 131 of the wireless receiving device is parallel to the extending direction of the axis A of the wireless receiving device. Specifically, the axis B of the housing extends in the front-rear direction, while the axis A of the wireless receiving device extends in the up-down direction. The wireless receiving device 130 is located above the housing 111 and the orientation of the signal receiving surface 131 of the wireless receiving device is upward, that is, facing away from the housing 111. When the above turning tool 100 is installed on the tool disc 500, as Figure 5 and Figure 6As shown, the cutter disc 500 located on the cutter disc mounting seat 600 is formed with a plurality of tool clamping positions 510 for mounting the turning tool 100, and the turning tool 100 can be placed on the tool clamping position 510 and clamped by the cutter disc 500. At the same time, a bracket 700 is provided on the side of the cutter disc mounting seat 600, and a wireless transmitting device 800 is provided on the bracket 700, and the wireless transmitting device 800 and the wireless receiving device 130 of the turning tool 100 can be arranged opposite to each other. Since the wireless receiving device 130 is located above the housing 111, the wireless transmitting device 800 arranged opposite to the wireless receiving device 130 can be placed above the entire turning tool 100, and the distance between the bracket 700 and the side of the cutter disc 500 is greater than the length of the turning tool 100 extending out of the side of the cutter disc 500. Therefore, during the tool change process of the tool disc 500 rotating, the wireless transmitting device 130 will not limit the tool change process. When the entire turning tool 100 is replaced by moving horizontally, it will be difficult to interfere with the wireless transmitting device 800, thereby avoiding the influence of the wireless transmitting device 800 on the replacement of the turning tool 100.

[0048] It should be noted that the orientation of the signal receiving surface 131 of the wireless receiving device determines the position and orientation in which the wireless receiving device can receive signals. Figure 1 As shown, the signal receiving surface 131 of the wireless receiving device faces upward. At this time, the wireless transmitting device 800 should be located above the signal receiving surface of the wireless receiving device and the wireless transmitting surface of the wireless transmitting device 800 faces downward to better transmit electromagnetic signals.

[0049] In other optional embodiments, such as Figure 7 As shown, the axis A of the wireless receiving device is parallel to the axis B of the shell, an adapter 400 is provided between the wireless receiving device and the tool rod 110, the signal receiving surface 131 of the wireless receiving device is oriented parallel to and the same as the direction in which the axis A of the wireless receiving device extends forward, and a wire channel is provided in the adapter 400 for the wiring harness 900 to electrically connect the wireless receiving device and the transducer 112.

[0050] Specifically, the axis B of the shell of the turning tool 100 and the axis A of the wireless receiving device extend from the rear side to the front side of the turning tool, and the adapter 400 extends in the up-down direction, the bottom of the adapter 400 is connected to the turning tool rod 110, and the top of the adapter 400 is connected to the wireless receiving device 130. A wire channel extending up and down is formed in the adapter 400, and the wire harness located in the wire channel can be electrically connected to the wireless receiving device and the transducer 112, so that current can be transmitted from the wireless receiving device to the transducer 112 through the wire harness. More specifically, one end of the wire harness is connected to the first coil 133 of the wireless receiving device, and the other end of the wire harness passes through the first wire channel 1344, the wire channel of the adapter 400 and the wire hole 1115 in sequence, and is finally connected to the transducer 112. When the turning tool 100 is installed on the tool disc, as shown in FIG.Figure 8 As shown, it is not difficult to find that at this time, the wireless transmission device 800 can still be placed above the entire turning tool 100. Therefore, when the turning tool 100 is replaced by rotating the tool disc horizontally, it is also difficult for the turning tool 100 to interfere with the wireless transmission device 800, thereby avoiding the influence of the wireless transmission device 800 on the replacement of the turning tool 100. It should be noted that referring to Figure 7 , the lower end of the adapter 400 can also be connected before the tool tip 120 and the clamped position of the tool shank, so as to avoid the adapter interfering with the clamping of the turning tool. At the same time Figure 7 in this application, it is only necessary to define that the adapter can allow the wire harness to pass through, and the width of the adapter extending along the axis B direction of the housing is not limited in this application.

[0051] In some alternative embodiments, as Figure 9 shown, the tool tip includes a blade 121 and a gasket 122. Specifically, the front end of the housing 111 extends forward to form a mounting portion 113. The mounting portion 113 is formed with a tool tip cavity 1131, and the tool tip cavity 1131 is consistent with the local shapes of the blade 121 and the gasket 122. The blade 121 and the gasket 122 can be placed in the tool tip cavity 1131 and expose the front ends of both. Secondly, the housing 111 is provided with a blade pressing block 114, which can press the blade 121 and the gasket 122 against the mounting portion 113 from right to left. More specifically, the gasket 122 is provided with a centering post 1221, and centering through holes are formed on the blade 121 and the mounting portion 113. The centering post 1221 can be inserted into the centering through holes of the blade 121 and the mounting portion 113 respectively to ensure the relative fixation of the positions of the blade 121, the gasket 122 and the mounting portion 113.

[0052] Optionally, as Figures 2-4 shown, in the extending direction of the axis A of the wireless receiving device, the wireless receiving device 130 is provided with a first wire passing channel 1344. The housing 111 is provided with a wire passing hole 1115 communicating with the first wire passing channel 1344. The wire harness 900 passes through the first wire passing channel 1344 and the wire passing hole 1115 to electrically connect the transducer 112 and the first coil 133 wound around the first magnetic core 132 in the wireless receiving device 130.

[0053] It should be noted that, as Figures 10-13 shown, the wireless receiving device 130 normally has a first magnetic core 132 and a first coil 133. The first coil 133 is wound around the first magnetic core 132, and the first coil 133 is connected to the transducer 112 through the wire harness 900. Therefore, the current in the first coil 133 can be transmitted to the transducer 112. Secondly, referring to Figure 19 and Figure 20, the wireless transmitting device 800 has a second magnetic core 820 and a second coil, and the second coil is wound around the second magnetic core 820. Therefore, the wireless transmitting device 800 can generate a magnetic field with the received electrical energy signal through the second magnetic core 820 and the second coil, while the wireless receiving device 130 can restore the magnetic field generated by the wireless transmitting device 800 into an electrical energy signal through the first magnetic core 132 and the first coil 133 and transmit it to the transducer 112, so that the transducer 112 generates vibrations. It should be noted that the first magnetic core 132 and the second magnetic core 820 can be ferrite.

[0054] Continue to refer to Figures 1-4 , in some alternative embodiments, the housing 111 includes a transducer housing 1111 and a wire threading housing 1112 provided at the rear end of the transducer housing 1111. The axis of the wire threading housing 1112 coincides with the axis of the transducer housing 1111, extending the length of the tool shank to facilitate the installation of the wireless receiving device and the tool holder for clamping the tool. The wire threading housing 1112 is detachably connected to the transducer housing 1111. An annular sealing elastic member 140 is provided between the wire threading housing 1112 and the transducer housing 1111. The wireless receiving device 130 is installed in the wire threading housing 1112. Specifically, the sealing elastic member 140 is fixed to the transducer housing 1111. A plurality of first through holes 141 are provided on the sealing elastic member 140. A plurality of threaded holes 1113 are formed at the rear end of the transducer housing 1111. The plurality of threaded holes 1113 of the transducer housing 1111 correspond to the plurality of first through holes 141 of the sealing elastic member 140 one by one, and the corresponding threaded holes 1113 and the first through holes 141 are oppositely arranged. In addition, a plurality of second through holes 1114 are formed on the wire threading housing 1112. The plurality of second through holes 1114 correspond to the plurality of first through holes 141 one by one and the corresponding second through holes 1114 and the first through holes 141 are oppositely arranged. Therefore, the first screw 1116 can sequentially pass through the second through hole 1114 and the first through hole 141 from back to front and finally be threadedly connected to the threaded hole 1113, thereby detachably connecting the wire threading housing 1112 and the transducer housing 1111 together.

[0055] It should be noted that, as Figure 2 shown, the axis of the wire threading housing 1112 coincides with the axis of the transducer housing 1111, and the directions and positions of both of them and the axis B of the housing are the same. However, in some alternative embodiments, the axis of the wire threading housing 1112 and the axis of the transducer housing 1111 can be parallel to each other instead of completely coinciding.

[0056] In addition, the middle part of the annular sealing elastic member 140 has a third through hole 142 for the wire harness 900 to pass through.

[0057] In the above solution, first, the sealing elastic member 140 can effectively prevent external contaminants such as dust and impurities from entering the wire threading housing 1112 and the transducer housing 1111 through the gap between the wire threading housing 1112 and the transducer housing 1111. In addition, the sealing elastic member 140 can form a buffer, thereby reducing the vibration between the wire threading housing 1112 and the transducer housing 1111.

[0058] It should be noted that under normal circumstances, the tool clamping position 510 of the cutter head 500 will clamp the transducer housing and the wire threading housing 1112 (or only clamp the wire threading housing 1112) to fixedly install the turning tool 100. In some alternative embodiments, since a long clamping portion is not required, the wire threading housing 1112 can be replaced with a sealing cover plate (a through hole should be provided in the sealing cover plate for the wire harness to pass through), and the turning tool 100 is connected to the cutter head 500 through the sealing cover plate.

[0059] In addition, in some alternative embodiments, the transducer is relatively long, and the corresponding transducer housing 1111 is also relatively long. At this time, a sealing cover plate can be selected to replace the wire threading housing 1112.

[0060] Continuing to refer to Figures 10-13 , the wireless receiving device 130 further includes a receiving ring 134. The receiving ring 134 includes a first ring portion 1341 and a second ring portion 1342 connected to each other. The first ring portion 1341 is located below the second ring portion 1342, and the bottom of the first ring portion 1341 is connected to the upper side surface of the wire threading housing 1112. A magnetic core cavity 1343 is formed above the second ring portion 1342 to accommodate the first magnetic core 132. Two first wire threading channels 1344 are formed in the first ring portion 1341, and the upper ends of the first wire threading channels 1344 communicate with the magnetic core cavity 1343, and the lower ends of the first wire threading channels 1344 communicate with the corresponding wire passing holes 1115 of the housing 111. Therefore, the wire harness 900 connected to one end of the first coil 133 can pass through the magnetic core cavity 1343, sequentially pass through the first wire threading channels 1344 and the wire passing holes 1115, and finally be connected to the transducer 112 located inside the housing 111.

[0061] It should be noted that the number of the first wire threading channels 1344 can be adjusted according to the actual situation, and is not limited to 1 or 2. Specifically, different transducers 112 require different numbers of wire harnesses 900, so the number of the first wire threading channels 1344 corresponding to the number of the wire harnesses 900 can naturally be different.

[0062] In addition, optionally, the receiving ring 134 is detachably mounted on the housing 111 by a second screw 135. Specifically, the second screw 135 passes through the second ring portion 1342 and the first ring portion 1341 to be threadedly connected to the housing 111, and the nut of the second screw 135 abuts against the receiving ring 134 to mount the receiving ring 134 on the housing 111.

[0063] Optionally, a coil cavity 1323 is formed in the first magnetic core 132 to accommodate the first coil 133, and the coil cavity 1323 is of an annular structure. Specifically, the first magnetic core 132 is formed with an inner side wall body 1321 and an outer side wall body 1322, and the coil cavity 1323 is formed between the inner side wall body 1321 and the outer side wall body 1322. The first coil is located in the coil cavity 1323 and wound around the outside of the inner side wall body 1321. An opening 1324 is formed in the inner side wall body 1321, so that the wire harness 900 can pass through the opening 1324 from the coil cavity 1323 and extend to the first wire threading channel 1344.

[0064] In addition, a sealing ring 136 can be provided between the wireless receiving device 130 and the housing 111 to prevent external contamination from entering the housing 111 through the gap between the wireless receiving device 130 and the housing 111.

[0065] Optionally, the tip C of the cutting tool head and the rear end face D of the bolt of the transducer are configured to be both located at the place where the vibration amplitude of the cutting tool 100 is the largest, and the connection part between the cutting tool head 120 and the housing 111 is located at the vibration node position of the cutting tool. It should be noted that the vibration node position refers to the intersection node where the vibration mode intersects with the original shape under a certain natural frequency of the structure, and the amplitude at the vibration mode node is the smallest.

[0066] First of all, since the housing 111 is normally installed and fixed on the tool holder 500, the housing 111 may affect the vibration of the cutting tool head 120. Therefore, by making the connection part between the cutting tool head 120 and the housing 111 located at the vibration node position of the cutting tool 100, the influence of the housing 111 on the vibration of the cutting tool head 120 is reduced, the energy loss is reduced, and the vibration amplitude at the tip C can reach the maximum at the resonant frequency. Secondly, since the tip C of the cutting tool head and the rear end face D of the bolt of the transducer are configured to be both located at the place where the vibration amplitude of the cutting tool 100 is the largest and they are located at the front and rear ends respectively, the amplitudes of the tip C and the rear end face D of the bolt of the transducer 112 can reach a balanced state, making the resonant frequency of the ultrasonic cutting tool 100 more stable, not prone to fluctuations, and facilitating the ultrasonic power supply to search for the resonant frequency.

[0067] Specifically, as Figure 3As shown, the transducer housing 1111 is formed with a transducer cavity 1117 to accommodate the transducer 112. Secondly, the screw of the bolt 1121 of the transducer 112 can pass through the transducer 112 to connect with the front end of the transducer cavity 1117, and the nut of the bolt 1121 presses against the piezoelectric ceramic and the electrode plate on the transducer 112 to mount and fix the piezoelectric ceramic and the electrode plate on the transducer 112 to the transducer housing 1111. In addition, the tool bit 120 is located in front of the transducer housing 1111, so the tool bit 120, the connection between the tool bit 120 and the housing 111, and the bolt 1121 of the transducer 112 are distributed in the direction from the front side to the rear side of the tool.

[0068] In addition, the ultrasonic tool structure of the present application, in addition to as Figures 1-3 and Figure 7 shown, can also be other arrangements. Specifically as Figures 14-16 shown, the wireless receiving device 130 is arranged to extend along the circumferential direction of the tool shank 110, and the wireless receiving device 130 is located between the clamped position (not marked in the figure) of the tool shank 110 and the tool bit 120. The signal receiving surface 131 of the wireless receiving device faces forward or the signal receiving surface 131 of the wireless receiving device faces outward and the orientation is perpendicular to the front and rear direction of the tool.

[0069] It should be noted that the tool shank 110 will be clamped on the tool holder or the tool disc 500, and the position where the tool shank 110 is clamped is the clamped position, that is, structures such as the tool holder or the tool disc 500 clamp the tool shank 110 at the clamped position of the tool shank 110 to mount and fix the tool 100. For details, reference can be made to Figure 17 .

[0070] The wireless receiving device 130 is arranged along the circumferential direction of the tool shank 110 specifically means that the wireless receiving device 130 is arranged around the outer periphery of the tool shank 110. The wireless receiving device 130 can be a ring structure to surround the tool shank, or the wireless receiving device 130 is an arc that is not 360° and travels along the circumferential direction of the tool shank 110. Among them, the wireless receiving device can be a circular ring surrounding the side of the tool shank, or the wireless receiving device is an arc, or the wireless receiving device is a square matching the shape of the tool shank or a square with an opening, or other shapes matching the side of the ultrasonic tool shank. For the above-mentioned arranged wireless receiving device, there are at least two optional implementation manners for its orientation.

[0071] For the above-mentioned first wireless receiving device, as Figures 14-17 shown, the wireless receiving device 130 faces the front of the tool. And the wireless transmitting device 800 should be arranged in front of the wireless receiving device 130 and is formed with a shape corresponding to the wireless receiving device, such as an arc or a ring or other shapes matching the wireless receiving device.

[0072] For the second wireless receiving device described above, as Figure 18 shown, the orientation of the wireless receiving device faces outward, i.e., away from the housing 111 of the turning tool 100, and the orientation of the receiving surface 131 of the wireless receiving device is perpendicular to the up-down direction.

[0073] In addition, the present disclosure provides a turning tool clamping seat. As Figure 5 、 Figure 6 and Figure 8 shown, it includes a tool disk 500, a bracket 700, and a tool disk mounting seat 600. The tool disk 500 is rotatably mounted on the tool disk mounting seat 600. The tool disk 500 is formed with a plurality of tool clamping positions 510 for mounting the turning tool 100. One end of the bracket 700 is provided at the rear of the tool disk 500 and connected to the tool disk mounting seat 600. The other end of the bracket 700 is provided with a wireless transmitting device 800. The other end of the bracket 700 bypasses the tool disk 500 and extends forward from the rear of the tool disk 500, so that the signal transmitting surface of the wireless transmitting device 800 is arranged opposite to the signal receiving surface 131 of the wireless receiving device.

[0074] Since the bracket 700 is connected to the tool disk mounting seat 600, when the tool disk 500 rotates relative to the tool disk mounting seat 600, the bracket 700 and the wireless transmitting device 800 on the bracket 700 will not move, while the tool disk 500 and the turning tool 100 located on the tool disk 500 will rotate. Therefore, the user can replace the turning tool 100 arranged opposite to the wireless transmitting device 800 according to the situation, and then supply power to the turning tool 100 to process the workpiece.

[0075] Specifically, the rear side of the tool disk 500 is mounted on the tool disk mounting seat 600, and the front end surface of the tool disk 500 is formed with a plurality of tool clamping positions 510 for mounting the turning tool 100. Refer to Figure 6, in the direction from the rear of the cutter head towards the front of the cutter head, the support 700 includes a first support 710, a second support 720, and a third support 730 connected in sequence. One end of the first support 710 is connected to the cutter head mounting seat 600, and the other end is connected to the rear end of the second support 720. The front end of the second support 720 is connected to one end of the third support 730. The other end of the third support 730 is located in front of the end face of the turning tool 100 mounted on the cutter head 500 and is provided with a wireless transmission device 800, and the signal transmission surface of the wireless transmission device 800 is arranged backward to be oppositely arranged with the signal receiving surface 131 of the forwardly arranged wireless receiving device. Among them, the first support 710, the second support 720, and the third support 730 are telescopic. In addition, the first support 710 and the third support 730 are parallel to the front end face of the cutter head 500 and perpendicular to the axis of the cutter head 500, and the second support 720 is perpendicular to the front end face of the cutter head 500 and parallel to the axis of the cutter head 500. In addition, in some embodiments, the situation of the support 700 can be adjusted according to the situation. For example, the support 700 can be telescoped in the direction parallel to the axis of the cutter head 500 or in the direction perpendicular to the axis of the cutter head 500, and it is not necessarily required that the support 700 be telescoped simultaneously in the direction parallel to the axis of the cutter head 500 and in the direction perpendicular to the axis of the cutter head 500.

[0076] Regarding the telescopic design, a first part and a second part can be formed in the first support 710. Both the first part and the second part are provided with a plurality of through holes, and the first part can be inserted into the second part. By inserting the first part into different positions in the second part, the length of the first support 710 can be telescoped. And the positions of the first part and the second part can be locked by sequentially passing bolts through the through holes of the first part and the second part. When it is necessary to adjust the position of the first support 710, the bolts can be taken out to adjust the relative positions of the first part and the second part. Similarly, the second support 720 and the third support 730 can also adopt the above method to achieve telescoping. It should be noted that the support realizes automatic telescoping through a cylinder, a gear, an elastic member, etc. connected to the driving device. The driving device can be in a gas-driven manner or an electric-driven manner. The telescoping methods of the support are diverse and not limited to the above methods.

[0077] In some embodiments, as Figure 17 shown, the wireless transmission device 800 is arc-shaped and the central angle is less than or equal to 180°. This wireless transmission device 800 is mainly for such as Figures 14-17The turning tool 100 shown. For this turning tool, the wireless transmission device 800 needs to be sleeved outside the turning tool 100 so that the signal transmission surface of the wireless transmission device 800 is arranged opposite to the signal reception surface 131 of the wireless reception device of the turning tool 100. Therefore, if the wireless transmission device 800 is set to be annular, the difficulty of replacing the turning tool will be greatly increased. And in the present disclosure, it is set to be arc-shaped, and the central angle is less than or equal to 180°, which can make the replacement of the entire turning tool more convenient.

[0078] Specifically, as Figure 17 shown, the wireless transmission device 800 is arc-shaped and is arranged opposite to the wireless reception device 130. When replacing the turning tool 100, the user only needs to move the wireless transmission device along the arrow direction (i.e., the opposite direction of the sixth direction R) through the telescopic bracket 700. Then rotate the turret to replace the turning tool 100. After the replacement of the turning tool 100 is completed, the wireless transmission device 800 can be reset, so that the wireless transmission device 800 is arranged opposite to the wireless reception device 130 of the replaced turning tool 100. In some alternative embodiments, as Figure 17 shown, the arc-shaped opening of the wireless transmission device 800 faces the front of the turret to surround the tool tip 120. Therefore, when the bracket 700 contracts in the direction of the rear of the turret, the wireless transmission device 800 and the wireless reception device 130 will no longer be arranged opposite to each other. At this time, it is not difficult to see that one end of the bracket 700 installed with the wireless transmission device 800 is located on the side of the turret 500, and the bracket 700 does not need to go around to the front of the end face of the turret 500 where the turning tool is installed.

[0079] In order to ensure that after the turret 500 rotates, the wireless reception devices 130 of the turning tools 100 on the turret 500 can be arranged opposite to the wireless transmission devices 800 on the bracket, so in some alternative embodiments, as Figure 5 shown, the turret 500 rotates around the first axis O, and the axis A of the wireless reception device of each turning tool 100 is parallel to the first axis O. Specifically, the first axis O is the axis of the turret 500 and extends along the front-rear direction of the turret 500.

[0080] In some alternative embodiments, as Figure 19 and Figure 20 shown, the wireless transmission device 800 includes a transmission device housing 810, a second magnetic core 820, and a connector 830. Among them, the second magnetic core 820 and the connector 830 are installed in the transmission device housing 810, and a cavity is formed in the second magnetic core 820 to place the second coil. Secondly, a wire harness channel is formed between the transmission device housing 810 and the second magnetic core 820 for the wire harness to extend from the second coil to the connector 830, and then be connected to an external power supply through the connector 830. And in some embodiments, the connector 830 can be a waterproof connector 830.

[0081] In addition, the present disclosure also provides a machine tool 1000, as Figure 21 shown, including a turntable 1100 for clamping a workpiece, a turning tool 100, a turning tool clamping seat, and a workbench 1200 that can move along a first direction P and a second direction Q. A driving device for driving the tool disc 500 to rotate is provided in the tool disc mounting seat 600. The tool disc mounting seat 600 is mounted on the workbench 1200. The tool disc mounting seat 600 can reciprocate along the first direction P and / or the second direction Q with the workbench 1200. And the end face of the turning tool 100 mounted on the tool disc 500 and the end face of the workpiece clamped by the turntable 1100 are located in two opposite planes. Optionally, a control panel 1300 is provided on the machine tool 1000, and the movement of the workbench 1200 and the rotation of the tool disc 500 can be controlled through the control panel 1300. Specifically, the first direction P is parallel to the direction of the first axis O, and the second direction Q is perpendicular to the first direction P. Therefore, it is not difficult to find that the tool disc 500 can move along the front-back direction and the left-right direction of the tool disc with the workbench 1200, thereby driving the turning tool 100 to complete the machining of the workpiece.

[0082] During use, the movement of the workbench 1200 can be controlled through the control panel 1300, so as to drive the tool disc 500 on the workbench 1200 to move along the first direction P and the second direction Q to approach the workpiece on the turntable 1100. Until the turning tool 100 opposite to the wireless transmission device 800 on the tool disc 500 reaches a predetermined position, the wireless transmission device 800 wirelessly supplies power to the transducer 112 in the turning tool 100 through the wireless receiving device 130 of the turning tool 100. The transducer 112 generates vibrations and transmits them to the tool tip 120, so that the tool tip 120 can process the workpiece.

[0083] When the tool tip 120 cannot meet the process requirements, the tool disc 500 can be manipulated to rotate, so that other turning tools in the tool disc 500 rotate, and the wireless receiving device 130 of this turning tool is opposite to the wireless transmission device 800. At this time, the wireless transmission device 800 can transmit electromagnetic signals to this turning tool 100, and the transducer 112 of the turning tool 100 starts to work and drives the tool tip 120 of the turning tool 100 to vibrate to process the workpiece.

[0084] In addition, once some of the turning tools 100 are relatively long and touch the bracket during the rotation of the tool disc 500, which affects the rotation of the tool disc 500. The user can adjust the length of the telescopic bracket at any time so that the bracket no longer hinders the rotation of the tool disc 500.

[0085] In the above solution, by arranging the wireless receiving device 130 on the side of the turning tool housing 111, it is more convenient to replace the turning tool 100 without being interfered by the wireless transmitting device 800. Moreover, in this solution, multiple turning tools 100 are provided on the tool disc 500, and the relative positions of the turning tools on the tool disc 500 and the wireless transmitting device 800 can be adjusted by rotating the tool disc and telescoping the bracket, so that the wireless receiving device 130 of the replaced turning tool 100 and the wireless transmitting device 800 can be more conveniently matched, and finally the replacement of the turning tool is completed. The above solution avoids disassembling and assembling the turning tool head multiple times, and there is no longer a need to disassemble and assemble the transducer on the turning tool to replace the tool.

[0086] The technical means of this application are not limited to the technical means disclosed in the above embodiments, but also include technical solutions formed by any combination of the above technical features. It should be noted that for those of ordinary skill in the art of this technology, without departing from the principle of this application, several improvements and refinements can be made, and these improvements and refinements are also regarded as the protection scope of this application.
