Description

Technical Field

[0001] The utility model relates to the field of ultrasonic machining, in particular to an ultrasonic vibration group-axis tool handle and a system thereof. Background Art

[0002] Mechanical parts often have structures that are arranged repeatedly according to a certain pattern, such as slots and holes. If they are processed in the conventional form using a single spindle, a single tool holder, and a single tool, a large number of repeated processing paths are required, and the processing efficiency is low. In the field of machining, there are also applications using multi-spindle machine tools for processing, but considering the overall versatility and economy, most conventional machine tools only have one spindle system. On conventional machine tools, the processing efficiency of repetitive structures can be greatly improved by using a tool holder to transform a single axis into a multi-axis structure, while different forms of tool holders can be used to adapt to different processing scenarios. This type of tool holder is generally called a multi-axis device, which is a new type of processing equipment that can greatly improve the processing efficiency for repetitive structures such as holes. However, ordinary multi-axis devices have low speeds and large cutting forces, making it difficult to process hard and brittle materials, composite materials, or difficult-to-process metal materials. The corresponding processing quality is poor and the efficiency is low.

[0051] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be understood to indicate or imply relative importance or implicitly specify the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of such features.

[0052] To facilitate the explanation of the positional relationship between the various structures, the "front" described in the various embodiments of the present invention refers to the direction of the installation position of the tool in the integral ultrasonic vibration group-axis tool holder, and the "back" refers to the direction opposite to the "front".

[0053] Ultrasonic machining is a special machining technology that gradually breaks the surface of the workpiece material. Ultrasonic machining uses the high-frequency, small-amplitude vibration generated by the ultrasonic tool holder to drive the machining tool to vibrate, and is commonly used for milling, drilling, turning and polishing. The ultrasonic tool holder is mainly composed of an ultrasonic vibration system and a tool holder component. Nowadays, ultrasonic tool holders mostly use spring chucks to clamp the tool, which also makes the tool holder more interchangeable when used and easier to install. Based on ultrasonic machining, the utility model proposes an ultrasonic vibration multi-axis tool holder and its system, which can greatly improve the machining efficiency and solve the problems of the existing multi-axis device, such as low speed, high cutting force, difficulty in machining hard and brittle materials, composite materials or difficult-to-machine metal materials, and corresponding poor machining quality and low efficiency.

[0055] Combine Figure 1 and Figure 2 The first embodiment of the present invention discloses an ultrasonic vibration group-axis tool holder, which is composed of a power input component 1, an ultrasonic group-axis component 2 and a primary side component 3.

[0056] Combine Figure 3The power input assembly 1 includes a power input base 11, a power input handle 12 and a first gear 13. The power input handle 12 is fixedly connected to the power input base 11, and the first gear 13 is connected to the front end of the power input handle 12. Specifically, the power input assembly 1 also includes a first bearing 14 and a first sleeve 15. A first countersunk hole 111 is provided on the power input base 11. A first step 1111 is provided in the first countersunk hole 111. The front end of the power input handle 12 is inserted from the rear end of the first countersunk hole 111. The first bearing 14, the first sleeve 15 and the first gear 13 are sequentially passed through and fixedly connected to the front end of the power input handle 12. The outer ring of the first bearing 14 is fixedly connected to the first countersunk hole 111 and the rear end of the first bearing 14 abuts against the first step 1111, so that the power input handle 12 is fixedly connected to the power input base 11. The main head (rear end) of the power input shank 12 can be modified in shape and size as needed to allow installation on different processing devices. The inner ring of the first bearing 14 is interference-fitted with the axial end of the power input shank 12 to withstand large biaxial and radial loads. The first gear 13 is fixed to the power input shank 12 and pre-tightened by the first sleeve 15. The outer ring of the first bearing 14 is fixedly connected to the power input base 11 to form a power input assembly 1 with high rigidity and high speed. In a specific embodiment, the first bearing 14 can be a double-row angular contact bearing, which can withstand both axial and radial forces and is suitable for being located at the position of the first bearing 14 to withstand the entire weight of the ultrasonic vibration group-axis shank.

[0057] The ultrasonic group axis assembly 2 includes an ultrasonic group axis base 21 and a plurality of ultrasonic tool handle modules 22. The ultrasonic group axis base 21 is fixedly connected to the power input base 11. Specifically, the power input base 11 is fixedly connected to the ultrasonic group axis base 21 through a plurality of first locking screws 16 equally distributed along the circumferential direction. Each first locking screw 16 passes through a hole opened on the power input base 11 and is fixedly connected to a threaded hole on the ultrasonic group axis base 21. Figure 4Each ultrasonic tool handle module 22 includes a rotating shaft 221, an ultrasonic transducer 222, a secondary side unit 223 and a second gear 224. Each rotating shaft 221 is fixedly connected to the ultrasonic group shaft base 21, the ultrasonic transducer 222 is fixedly connected to the front end of the rotating shaft 221, the second gear 224 is fixedly connected to the rear end of the rotating shaft 221, the secondary side unit 223 is fixedly connected to the outer ring of the rotating shaft 221 and is electrically connected to the ultrasonic transducer 222, and the front end of the ultrasonic transducer 222 is used to fixedly connect the ultrasonic machining tool 5. Specifically, each ultrasonic blade handle module 22 also includes a second bearing 225 and a second sleeve 226. A plurality of second countersunk holes 211 are defined in the ultrasonic group shaft base 21. The second bearing 225, second sleeve 226, and second gear 224 are sequentially disposed through and fixedly connected to the rear end of the rotating shaft 221. A second step 2212 is defined at the rear end of the rotating shaft 221. The outer ring of the second bearing 225 is fixedly connected to the second countersunk hole 211, and the front end of the second bearing 225 abuts against the second step 2212. In a specific embodiment, the second bearing 225 utilizes a deep groove ball bearing, which can withstand radial forces during rotation.

[0058] The front end of the rotating shaft 221 defines a cavity 2211, and the rear end of the ultrasonic transducer 222 is housed within the cavity 2211. The secondary unit 223 is fixedly connected to the outer ring of the rotating shaft 221 corresponding to the cavity 2211. The secondary unit 223 includes a secondary magnetic core 2231 and a secondary magnetic core bracket 2232. The secondary magnetic core 2231 is fixedly connected within the secondary magnetic core bracket 2232, which is fixedly connected to the middle of the rotating shaft 221. The secondary magnetic core 2231 is used to receive high-frequency ultrasonic signals when the ultrasonic handle module 222 rotates at high speed.

[0059] Specifically, each ultrasonic handle module 22 also includes a pressure cover 227, and the ultrasonic transducer 222 includes a rear cover plate 2221, multiple electrode sheets 2222, multiple piezoelectric ceramic sheets 2223 and an amplitude transformer 2224. The amplitude transformer 2224 is provided with a flange 22241. The multiple electrode sheets 2222 and the multiple piezoelectric ceramic sheets 2223 are coaxial and alternately arranged axially between the rear cover plate 2221 and the flange 22241 of the amplitude transformer 2224. The pressure cover 227 fixes the amplitude transformer 2224 to the rotating shaft 221 through the front end face of the flange 22241 of the amplitude transformer 2224. The rear end of the amplitude transformer 224 and the rear cover plate 2221, multiple electrode sheets 2222, and multiple piezoelectric ceramic sheets 2223 are all located in the cavity 2211. The tool 5 is fixedly connected to the front end of the amplitude variable rod 2224 through a spring collet 51 and a nut 52. The tool 5 is locked to the front end of the amplitude variable rod 2224 by tightening the nut 52. In this embodiment, the tool 5 is a drill bit, and the spring collet 51 can be replaced with drill bits of various specifications as needed.

[0060] Combine Figure 5, the first gear 13 is connected to the second gear 224 in each ultrasonic handle module 22 so that the rotation of the first gear 13 simultaneously drives the rotation of each second gear 24. In this embodiment, the axis of each second gear 224 is respectively located on the same circle with the axis of the first gear 13 as the center, and each second gear 224 is respectively engaged with the first gear 13. Specifically, the first gear 13 is larger than the second gear 224. In this example, the ultrasonic group axis assembly 2 includes four ultrasonic handle modules 22. Correspondingly, the first gear 13 is simultaneously engaged with the four second gears 224 to transmit power to the tool 5. The second gear 224 can be a small spur gear. It should be noted that the number, type and arrangement of the gears only need to be adjusted according to the specific requirements of processing the group holes. It can also be that the second gear 224 directly meshing with the first gear 13 drives other gears to rotate to form a variety of other transmission arrangements.

[0061] High-speed grease is added to the first bearing 14 and the second bearing 225 during installation, and no circulating lubrication is required; high-speed grease is used for the meshing of the first gear 13 and the second gear 224, and installation and maintenance are simple.

[0062] The primary side component 3 is connected to the ultrasonic generator 6 through a cable for receiving ultrasonic signals. Figure 6 The primary assembly 3 includes a primary base 31 and a plurality of primary units 32. The primary base 31 is fixedly connected to the ultrasonic group axis base 21. Specifically, the primary base 31 is fixedly connected to the ultrasonic group axis base 21 by a plurality of second locking screws 33 arranged equally along the circumference. Each second locking screw 33 passes through a hole in the primary base 31 and is fixedly connected to a threaded hole in the ultrasonic group axis base 21. The plurality of primary units 32 are respectively fixedly connected to the primary base 31, and each primary unit 32 is spaced apart and corresponds to a secondary unit 223 in each ultrasonic handle module 22, so that the ultrasonic signals received by each primary unit 32 are transmitted to each secondary unit 223. In this embodiment, the primary units 32 are correspondingly arranged at the front side of the secondary units 223. In other embodiments, the primary units 32 can also be correspondingly arranged at the outer ring or rear side of the secondary units 223.

[0063] Furthermore, a plurality of third countersunk holes 311 are provided on the primary substrate 31, and the primary unit 32 includes a primary magnetic core 321 and a primary magnetic core bracket 322, each primary magnetic core 321 is fixedly connected to the primary magnetic core bracket 322, and each primary magnetic core bracket 322 is respectively fixedly connected to each third countersunk hole 311 on the primary substrate 31 to distribute the received high-frequency ultrasonic signal to the plurality of primary magnetic cores 321.

[0064] The high-frequency ultrasonic transmission path is as follows: the ultrasonic generator 6 generates a high-frequency ultrasonic signal, which is transmitted to multiple primary magnetic cores 321 through the cable of the primary component 3. The secondary magnetic core 2231 receives the high-frequency ultrasonic signal of the primary magnetic core 321 under high-speed rotation. The multiple piezoelectric ceramic pieces 2223 installed on the amplitude rod 2224 undergo high-frequency deformation under the excitation of the high-frequency ultrasound of the secondary magnetic core 2231, and are finally transmitted to the tool 5 through the amplitude rod 2224. The tool end of the tool 5 generates high-frequency vibration with the maximum amplitude. In this way, the tool 5 (such as a drill bit) drills difficult-to-process composite materials under the dual effects of high-speed rotation and high-frequency vibration. The multiple ultrasonic tool holder modules 22 work together to improve the processing efficiency of the group holes, and the deformation of the workpiece is small, and the generation of burrs can be greatly reduced, thereby improving the processing quality.

[0065] The ultrasonic vibration group-axis tool holder provided in this embodiment can be used for processing group holes and group grooves in hard and brittle composite materials, and can also greatly improve the processing efficiency, quality, and processing stability of group holes and group grooves in ordinary materials.

[0066] Example 2

[0067] like Figure 1 and Figure 2 As shown, the second embodiment of the present invention discloses an ultrasonic vibration group-axis toolholder system, including an anti-rotation component 4 and the ultrasonic vibration group-axis toolholder of the first embodiment. The first end of the anti-rotation component 4 is fixedly connected to the ultrasonic vibration group-axis toolholder, and the second end is used to fix the spindle or spindle seat of the processing equipment (not shown in the figure). The anti-rotation component 4 is used to connect the spindle or spindle seat of the processing equipment to the ultrasonic vibration group-axis toolholder to prevent the ultrasonic vibration group-axis toolholder from rotating as a whole relative to the spindle or spindle seat of the processing equipment.

[0068] The anti-rotation assembly 4 includes a first clamping ring 41, a second clamping ring 42, a first locking member 43, a second locking member 44, a graphite copper sleeve 45, and a connecting shaft 46. The first clamping ring 41 includes a first sub-fixing ring 411, a second sub-fixing ring 412, and a first connecting portion 413. The first connecting portion 413 is connected between the open end of the first sub-fixing ring 411 and the open end of the second sub-fixing ring 412. The first locking member 43 is fixedly connected to the first connecting portion 413 to lock the open ends of the first and second sub-fixing rings 411, 412. When the open end of the first sub-fixing ring 411 is locked, the power input base 11 is fixedly connected to the first sub-fixing ring 411. When the open end of the second sub-fixing ring 412 is locked, the graphite copper sleeve 45 and the first end of the connecting shaft 46 are fixedly connected to the second sub-fixing ring 412. The first end of the connecting shaft 46 is sleeved on the inner ring of the graphite copper sleeve 45. The second clamping ring 42 includes a third sub-fixing ring 421, a fourth sub-fixing ring 422 and a second connecting portion 423. The second connecting portion 423 is connected between the open end of the third sub-fixing ring 421 and the open end of the fourth sub-fixing ring 422. The second locking member 44 is fixedly connected to the second connecting portion 423 to lock the open ends of the third sub-fixing ring 421 and the fourth sub-fixing ring 422. When the open end of the third sub-fixing ring 421 is locked, the spindle or the spindle seat (not shown in the figure) is fixedly connected to the third sub-fixing ring 421. When the open end of the fourth sub-fixing ring 422 is locked, the second end of the connecting shaft 46 is fixedly connected to the fourth sub-fixing ring 422. When the first locking member 43 locks the open ends of the first and second sub-fixing rings 411, 412, the second sub-fixing ring 412 is tightened and deformed, squeezing the graphite copper sleeve 45 and causing the graphite copper sleeve 45 to compress the first end of the connecting shaft 46. This prevents relative axial sliding between the connecting shaft 46 and the graphite copper sleeve 45 when the second clamping ring 42 is fixed to the spindle of the machining device, thereby improving positioning accuracy during machining through the anti-rotation assembly 4. The anti-rotation assembly 4 is used to prevent the ultrasonic vibration group-axis tool holder from rotating during operation, further enhancing the rigidity of the ultrasonic vibration group-axis tool holder.

[0069] The ultrasonic vibration group-axis toolholder system in this embodiment can be installed on a variety of processing devices. The front end of the ultrasonic vibration group-axis toolholder can be replaced with cutting tools of different specifications, which is highly adaptable and interactive.

[0070] Example 3

[0071] like Figure 7As shown, this embodiment discloses an ultrasonic vibration group axis tool handle. The difference between this embodiment and embodiment one lies in the different ultrasonic transmission modes. The ultrasonic transmission mode in embodiment one is up-down transmission, that is, the relative positions of the primary magnetic core 321 and the secondary magnetic core 2231 are distributed up and down; while the ultrasonic transmission mode in this embodiment is inside-outside transmission, that is, the relative positions of the primary magnetic core 321 and the secondary magnetic core 2231 are distributed inside-outside. Specifically, the primary magnetic core 321 is located on the outside of the secondary magnetic core 2231. The structural schematic diagram of the primary component 3 in this embodiment is shown in FIG. Figure 8 As shown, it is composed of a primary substrate 31 and a primary unit 32, and the primary unit 32 includes a primary magnetic core 321 and a primary magnetic core bracket 322, wherein the primary magnetic core 321 and the primary magnetic core bracket 322 are protruding from the upper surface of the primary substrate 31. Through the primary magnetic core 321 and the secondary magnetic core 2231 distributed inside and outside and arranged in a one-to-one correspondence with each other, high-frequency ultrasonic signals can be transmitted from the relatively stationary primary magnetic core 321 on the outside to the relatively high-speed rotating secondary magnetic core 2231 on the inside.

[0072] Apart from the above differences, other structures of this embodiment are similar to those of the first embodiment and will not be described again here.

[0075] Example 5

[0076] like Figure 9 As shown, this embodiment discloses an ultrasonic vibration multi-axis tool holder. The difference between this embodiment and the first embodiment lies in the fixed position of the secondary side unit 223 (i.e., the ultrasonic receiver). In the first embodiment, the secondary side unit 223 is fixedly connected to the outer ring of the middle part of the maximum diameter of the rotating shaft 221, and is fixed at the same position as the rear end of the ultrasonic transducer 222. The maximum diameter of the ultrasonic tool holder module 22 is the outer diameter of the secondary side unit 223. The secondary side unit 223 in this embodiment is fixed at the rear end of the ultrasonic transducer 222. Specifically, a third step 2213 is provided on the rotating shaft 221, and the third step 2213 is located on the rear side of the cavity 2211. The secondary side unit 223 is fixedly connected to the rear side of the rotating shaft 221 corresponding to the third step 2213, and the outer diameter of the secondary side unit 223 is less than or equal to the diameter of the outer circle of the rotating shaft 221 corresponding to the cavity 2211; at this time, the maximum diameter of the ultrasonic knife handle module 22 is the maximum diameter of the rotating shaft 221, thereby achieving the purpose of reducing the maximum diameter of the ultrasonic knife handle module 22 and making the internal layout more compact.

[0077] Correspondingly, the primary side unit 32 can be arranged at the front or rear side of the secondary side unit 223 at corresponding intervals. In this embodiment, the primary side matrix 31 and the ultrasonic group axis matrix 21 are fixedly connected as a whole, and each primary side unit 32 is fixedly connected to each second countersunk hole 211 of the ultrasonic group axis matrix 21.

[0078] Apart from the above differences, other structures of this embodiment are similar to those of the first embodiment and will not be described again here.

[0086] Embodiment 9

[0087] like Figure 11 and Figure 12 As shown, this embodiment discloses an ultrasonic vibration group axis tool holder. The difference between this embodiment and the first embodiment is that the arrangement and number of the ultrasonic tool holder modules 22 are changed according to the processing requirements. Figure 13 and Figure 14In this embodiment, each ultrasonic blade handle module 22 is divided into multiple groups of ultrasonic blade handle module groups, each group of ultrasonic blade handle module groups includes multiple ultrasonic blade handle modules 22, and the axis centers of the second gears 224 of each ultrasonic blade handle module 22 in each group of ultrasonic blade handle module groups are respectively located on the same circle with the axis center of the first gear 13 as the center; but the axis centers of the second gears 224 of the ultrasonic blade handle modules 22 in different groups of ultrasonic blade handle module groups are respectively located on different circles with the axis center of the first gear 13 as the center; and multiple gear transmission units 228 are provided between each two adjacent groups of ultrasonic blade handle module groups, so that when the second gears 224 of each ultrasonic blade handle module in the ultrasonic blade handle module group located on the inner side of the two adjacent groups of ultrasonic blade handle module groups rotate, the second gears 224 of each ultrasonic blade handle module in the ultrasonic blade handle module group located on the outer side can be driven to rotate through each gear transmission unit 228.

[0088] Specifically, the number of ultrasonic knife handle modules 22 in Example 1 is 4, and the number of ultrasonic knife handle modules 22 in this embodiment is 16, of which the 16 ultrasonic knife handle modules 22 are divided into two groups, namely, two inner and outer circles, with 8 distributed on the inner circle circumference of the ultrasonic group shaft base 21 and 8 distributed on the outer circle circumference. In order to ensure that the rotation directions of the ultrasonic knife handle modules 22 of the inner and outer circles are the same, 8 gear transmission units 228 are added between the second gears 224 of the inner and outer circles of the ultrasonic knife handle modules 22 for converting the rotation direction of the outer circle of the ultrasonic knife handle module 22.

[0089] like Figure 15 As shown, the structure of the primary side component 3 is similar to that of the first embodiment, and will not be repeated here.
