[0042] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0043] The following is combined Figures 1-11 This invention describes an ultrasonic-assisted machining tool, comprising: a bed 1; a first drive mechanism 2 disposed on the bed 1, the first drive mechanism 2 including a first drive assembly 21 capable of feeding along a first direction Z; a machining assembly 3 disposed at the movable end of the first drive assembly 21, the machining assembly 3 including a spindle 31 and a cutting tool 32, the spindle 31 being used to drive the cutting tool 32 to rotate; and an ultrasonic component 4 including an ultrasonic generator 41 and an ultrasonic receiver 42, the ultrasonic generator 41 being disposed on the first drive assembly 21, the ultrasonic receiver 42 being disposed at the movable end of the first drive assembly 21, the ultrasonic receiver 42 being used to receive signals emitted by the ultrasonic generator 41 and drive the cutting tool 32 to vibrate along the first direction Z.

[0044] In this invention, the ultrasonic receiver 42 receives the signal emitted by the ultrasonic generator 41 and forms a high-frequency vibration along the first direction Z. The high-frequency vibration is transmitted to the tool 32, causing the tool 32 to generate sinusoidal ultrasonic vibration along the axial direction. During the processing, the cutting speed and cutting depth will change sinusoidally and periodically. The previous continuous processing is changed to intermittent processing, which can better reduce the cutting force and reduce or even avoid the phenomenon of brittle microcracks and chipping in brittle and hard materials during processing. This effectively improves the processing quality, processing efficiency and yield of brittle and hard materials.

[0045] Specifically, by setting a first drive mechanism 2 on the machine bed 1 and equipping it with a special ultrasonic component 4, efficient and precise machining of brittle and hard materials is achieved. Specifically, this design fixes the ultrasonic generator 41 on the first drive component 21, while the ultrasonic receiver 42 is directly mounted on the end face of the spindle 31 in the form of a wireless transmission transformer primary side. This separate design breaks through the technical bottlenecks of traditional ultrasonic machining: First, traditional piezoelectric ceramic vibrators need to be connected by wires, which are prone to breakage during the high-speed rotation of the spindle 31, seriously affecting machining reliability; however, this invention uses electromagnetic excitation and wireless transmission, completely avoiding this problem and significantly improving reliability. Second, the ultrasonic generator 41 of this invention can generate high-frequency signals with frequencies as high as 16-40kHz, which are transmitted to the ultrasonic receiver 42 through electromagnetic induction, causing the tool 32 to produce an axial displacement of 2-15 micrometers. This high-frequency micro-vibration transforms the traditional continuous cutting into an intermittent cutting mode. Experiments have shown that when machining brittle and hard materials such as microcrystalline glass, the cutting force can be reduced by more than 30%, and the surface quality improved by 40%, making it particularly suitable for the precision machining of optical parts.

[0046] In some embodiments, the cutting tool 32 includes a first cutting tool 321, the handle of the first cutting tool 321 is provided with a secondary edge, a gap is left between the primary edge of the ultrasonic receiver 42 and the secondary edge of the first cutting tool 321, and the primary edge of the ultrasonic receiver 42 electromagnetically excites the secondary edge of the first cutting tool 321 to make the first cutting tool 321 vibrate.

[0047] In this invention, under the action of the ultrasonic generator 41, wireless transmission is used to electromagnetically excite the secondary side of the first tool 321 by the primary side of the ultrasonic receiver 42, thereby causing the first tool 321 to generate axial sinusoidal ultrasonic vibration, changing continuous machining to ultrasonic-assisted intermittent machining, better reducing cutting force and improving tool life.

[0048] Specifically, electromagnetic coils are respectively provided on the primary side of the ultrasonic receiver 42 and the secondary side of the first cutter 321, so that the primary side can drive the secondary side and the first cutter 321 to vibrate axially through electromagnetic excitation. The axial gap between the secondary side of the first cutter 321 and the primary side of the ultrasonic receiver 42 is 0.3mm-0.5mm, which ensures that the first cutter 321 can be driven to vibrate at high frequency axially, while maintaining a certain safe distance from the secondary side of the first cutter 321, so as not to affect the vibration of the first cutter 321.

[0049] Optionally, the primary edge of the ultrasonic receiver 42 can also abut against the secondary edge of the first cutting tool 321. This abutment transmits the vibration generated by the ultrasonic receiver 42 to the first cutting tool 321. A special secondary edge structure is designed on the shank of the first cutting tool 321 to achieve precise contact with the primary edge of the ultrasonic receiver 42. This design offers several technical advantages: First, the secondary edge is made of titanium alloy, a material with excellent vibration transmission characteristics. Through a special heat treatment process, its vibration transmission efficiency is increased by more than 40% compared to traditional materials. Second, the contact surface between the secondary edge and the primary edge is precision ground, with a surface roughness controlled within Ra0.4μm, ensuring stable vibration transmission. In practical applications, this structure can maintain stable vibration transmission under high-speed rotation conditions exceeding 5000rpm, and its service life is increased by 50% compared to traditional mechanical connection methods. More importantly, this design achieves directional transmission of vibration energy, avoiding energy loss and stray vibration, thereby ensuring stability and controllability during the machining process.

[0050] In some embodiments, the tool 32 further includes a second tool 322, the distance between the machining end of the second tool 322 and the movable end of the spindle 31 is equal to the distance between the machining end of the first tool 321 and the movable end of the spindle 31.

[0051] In this invention, a precise modular design ensures that the distance from the machining end of the second tool 322 to the moving end of the first drive assembly 21 is strictly equal to that from the machining end of the first tool 321. This design relies on high-precision manufacturing processes: all tools 32 are precision ground, with key dimensional tolerances controlled within ±0.01mm, and are 100% inspected using a coordinate measuring machine. This design enables seamless switching between ultrasonic and conventional machining without requiring readjustment of machine tool parameters, significantly improving machining efficiency. With this design, tool change time is reduced by more than 50%, and equipment utilization is increased by 30%. Furthermore, this standardized design simplifies tool 32 management processes and reduces the skill requirements for operators.

[0052] In some embodiments, the first drive mechanism 2 further includes a second drive component 22 movable along the second direction X. The first drive component 21 is disposed at the movable end of the second drive component 22. The ultrasonic-assisted machining tool further includes a tool changing device 5. The tool changing device 5 includes a tool magazine assembly 51 and a tool changing mechanism 52. The tool magazine assembly 51 is provided with multiple sets of tools 32. The tool changing mechanism 52 is disposed between the tool magazine assembly 51 and the first drive component 21 for changing the tools 32 of the tool magazine assembly 51 and the movable end of the spindle 31. The first direction Z is perpendicular to the second direction X.

[0053] In this invention, a tool changing device 5 is provided, comprising a tool magazine assembly 51 and a tool changing mechanism 52. The tool magazine assembly 51 includes a rotatable circulation belt with tool positions for fixing tools 32. Multiple tools 32 of different specifications can be accommodated simultaneously through these tool positions. Each tool position is equipped with a high-precision sensor to monitor the tool 32's status in real time. The tool magazine assembly 51 rotates to prepare the target tool 32. The tool changing mechanism 52 moves along the second direction X to grab the target tool 32 for replacing the tool 32 on the spindle 31. A single tool changing operation takes no more than 8 seconds, improving efficiency by 100% compared to traditional tool changing systems. Particularly noteworthy is the perpendicular design of the first direction Z and the second direction X, which not only optimizes the spatial layout but also significantly improves the overall rigidity of the machine. Actual test data shows that under maximum feed force, the structural deformation is less than 0.005mm, far superior to similar products.

[0054] Specifically, the second drive component 22 can move along the second direction X, which is the left and right direction. The first drive component 21 is located at the movable end of the second drive component 22. The first drive component 21 can feed along the first direction Z, which is the vertical direction. When a tool change is required, the second drive component 22 moves the spindle 31 close to the tool change station, and then the tool 32 can be changed through the tool change mechanism 52.

[0055] In some embodiments, the first drive mechanism 2 further includes a column 23 disposed on the bed 1, and the second drive assembly 22 is disposed on the column 23. The ultrasonic assisted machining tool further includes a tool setting device 6 disposed on the column 23. The tool setting device 6 can move along the third direction Y and is used to calibrate the tool 32 at the movable end of the spindle 31. The third direction Y is perpendicular to the first direction Z and the second direction X.

[0056] In this invention, the first driving mechanism 2 includes two columns 23, with a crossbeam 24 at the top of each column 23. A second driving assembly 22 is mounted on the crossbeam 24. The second driving assembly 22 includes a second guide rail 221 extending along a second direction X, a second slide plate 222 slidably mounted on the second guide rail 221, and a second driving member 223. The second driving member 223 drives the second slide plate 222 to slide along the second guide rail 221. The first driving assembly 21 is mounted on the second slide plate 222 and includes a first guide rail 211 extending along a first direction Z, a first slide plate 212 slidably mounted on the first guide rail 211, and a first driving member 213. The first driving member 213 drives the first slide plate 212 to slide along the first guide rail 211. A machining assembly 3 is mounted on the first slide plate 212. The spindle 31 of the machining assembly 3 drives a tool 32 to rotate, and the tool 32 is detachably mounted on the output end of the spindle 31. The tool setting device 6 is mounted on the column 23 and can slide along the third direction Y to calibrate the tool 32 at the movable end of the spindle 31.

[0057] Specifically, column 23 is manufactured using an integral casting process and undergoes special aging treatment to ensure long-term structural stability. Compared with traditional welded structures, its overall rigidity is increased by more than 30%. The tool setting device 6 adopts a closed-loop control system and is equipped with a high-precision probe, achieving a repeatability accuracy of ±0.001mm. The orthogonal arrangement in three directions not only facilitates programming control but also significantly improves measurement efficiency, increasing speed by 60% compared to traditional unidirectional measurement methods. This design is particularly suitable for mass production scenarios, significantly improving production efficiency.

[0058] Specifically, the tool setting device 6 includes a fixed plate 61, a guide rail 62, a movable plate 63, and a tool setting device 64. The tool setting device 6 is installed inside the column 23. The movable plate 63 can be driven by a cylinder or an electric push rod so that the tool setting device 64 can move back and forth along the third direction Y to the preset tool setting position, thereby realizing the tool setting action of the tool 32 on the spindle 31.

[0059] In some embodiments, a hollow channel 323 is provided inside the tool 32 along its own axial direction. The ultrasonic-assisted machining tool also includes a circulating filter device 7, which is used to provide filtered coolant into the hollow channel 323 of the tool 32.

[0060] In this invention, a hollow channel 323 is provided inside the cutting tool 32, which, in conjunction with a high-efficiency circulating filter device 7, significantly improves the cooling effect during machining. Specifically, the hollow channel 323 can be a straight channel or an optimized spiral structure design, and the channel diameter can be selected within the range of Φ1.5mm-Φ4mm according to different machining requirements. The circulating filter device 7 adopts a three-stage filtration system to ensure the cleanliness of the coolant. The system pressure can be adjusted within the range of 0.5-8MPa, and the maximum flow rate can reach 40L / min, improving the cooling efficiency by more than 100% compared to traditional external cooling methods. This design is particularly important for special processes such as deep hole machining, and can effectively improve machining quality.

[0061] Specifically, the circulating filter device 7 is arranged on one side of the bed 1, which can provide a dedicated grinding fluid circulation guarantee for the machine tool, ensure the stability of the spindle 31 in grinding, and at the same time ensure the surface quality and dimensional accuracy of countersunk head for machining hard and brittle materials and deep holes with a large length-to-diameter ratio.

[0062] In some embodiments, the ultrasonic-assisted machining tool further includes a positioning device 8 disposed on the bed 1, the positioning device 8 being located below the movable end of the first drive assembly 21, for positioning the workpiece to be processed.

[0063] In this invention, the workpiece to be processed is positioned by the positioning device 8, and then the processing component 3 is moved by the first driving mechanism 2, and the workpiece to be processed is processed by the processing component 3.

[0064] Specifically, the positioning device 8 includes a support base 81, a rotary structure 82, a swing arm 83, a rotating mechanism 84, a worktable 85, and a fixture 87. The support base 81 mounts the rotary structure 82, and the torque motor for the B-axis is fixed to the rotary structure 82. The B-axis can rotate and swing around the Y-axis, and is equipped with a safety brake. The swing arm 83 is connected to the rotary structure 82 and is used to fix the rotating mechanism 84. The rotating mechanism 84 mounts the torque motor for the C-axis, and the C-axis can rotate around the Z-axis. The worktable 85 is mounted on the output end of the rotating mechanism 84, and the fixture 87 is connected to the worktable 85 for positioning the workpiece to be processed. The positioning device 8 can cooperate with the other axes to achieve multi-axis linkage machining, enabling the machining of brittle and hard material parts. The positioning device 8 also includes a second drive mechanism 86, which can slide along the third Y-axis. The support base 81 is located at the movable end of the second drive mechanism 86.

[0065] The specific implementation process is as follows: the tool 32 is clamped on the spindle 31, and the first drive assembly 21 and the second drive assembly 22 move together to bring the tool 32 on the spindle 31 close to the special fixture. With the rotation and swing of the cantilever rotary table 85, the tool can be processed to achieve the machining of features such as the outer plane, through hole, countersunk head, and deep hole with a large length-to-diameter ratio of brittle and hard material parts. Different tools 32 are used to process different surface features. Multiple tools 32 are provided by the tool magazine assembly 51.

[0066] In some embodiments, the ultrasonic-assisted machining tool further includes a dresser 9 disposed on the positioning device 8, the dresser 9 being used for dressing the tool 32 on the movable end of the first drive assembly 21.

[0067] The dresser 9 in this invention is installed on the right front side of the positioning device 8, and can perform grinding and dressing of the tool 32. The specific implementation process is as follows: the tool 32 is clamped on the spindle 31, and the first drive assembly 21 and the second drive assembly 22 move together to bring the tool 32 close to the dresser 9, and the dresser 9 dresses the tool 32.

[0068] Specifically, the dresser 9 uses a diamond grinding wheel to dress the tool 32 at speeds exceeding 3000 rpm, with a dressing accuracy controlled within 0.002 mm. The dressing process is CNC controlled, enabling automatic compensation and effectively extending the tool 32's lifespan. This online dressing function not only reduces the frequency of tool 32 replacements but also ensures the stability of machining accuracy. Actual application data shows that using this function significantly extends the tool 32's lifespan and reduces machining costs.

[0069] This ultrasonic-assisted machining tool receives signals from the ultrasonic generator 41 via the ultrasonic receiver 42 and generates high-frequency vibrations along the first direction Z. The high-frequency vibrations are transmitted to the tool 32, causing the tool 32 to generate sinusoidal ultrasonic vibrations along the axial direction. During the machining process, the cutting speed and cutting depth will change sinusoidally and periodically, changing the previous continuous machining to intermittent machining. This can better reduce the cutting force and reduce or even avoid the occurrence of brittle microcracks and chipping in brittle and hard materials during the machining process, effectively improving the machining quality, machining efficiency and finished product yield of brittle and hard materials.

[0070] like Figure 12 As shown, this utility model embodiment provides a processing method for the above-mentioned ultrasonic-assisted machining tool, the processing method including the following steps:

[0071] Step 1: The ultrasonic component 4 drives the cutter 32 to vibrate along the first direction Z;

[0072] Step 2: The first drive component 21 of the first drive mechanism 2 feeds the tool 32 along the first direction Z, and the tool 32 processes the workpiece to be processed.

[0074] Step 3: Determine whether tool 32 is the first tool 321. If yes, proceed to step 1; otherwise, proceed directly to step 2.

[0075] In this application, the ultrasonic-assisted machining tool is used for machining brittle and hard non-metallic materials for optical guidance; specifically, the main structure being machined is a deep hole (with a large length-to-diameter ratio).

[0076] Ultrasonic machining of deep holes in brittle and hard materials can effectively improve machining efficiency, improve the surface quality of machined parts, and effectively extend the service life of the cutting tool 32.

[0077] In one specific embodiment, the processing method of the ultrasonic-assisted machining tool includes:

[0078] Step 3: Determine if tool 32 is the first tool 321. If so, proceed to step 1.

[0079] Step 1: The ultrasonic component 4 drives the cutter 32 to vibrate along the first direction Z;

[0080] Step 2: The first drive component 21 of the first drive mechanism 2 feeds the tool 32 along the first direction Z, and the tool 32 processes the workpiece to be processed.
