[0035] ReferenceFigure 1 、 Figure 2 and Figure 4 The utility model provides a chamfer device for ultrasonic transducer piezoelectric material, including clamping subassembly 1, sliding assembly 2 and grinding assembly 3, clamping subassembly 1 is equipped with clamping cavity 10 through, the workpiece is suitable for clamping in clamping cavity 10, clamping subassembly 1 still is equipped with inclined plane 121 in the top of one side of clamping cavity 10, sliding assembly 2 includes sliding plate 21 and sliding block 22, and sliding block 22 is located below the workpiece in clamping cavity 10, and the bottom of sliding block 22 is equipped with first inclined plane 221, and the top of sliding plate 21 is equipped with second inclined plane 211 with first inclined plane 221 matches, and sliding plate 21 is suitable for horizontal movement and drives sliding block 22 and workpiece vertical movement, grinding assembly 3 is suitable for slidingly arranged on inclined plane 121 and is suitable for grinding the part of workpiece that protrudes from clamping cavity 10.

[0036] In the embodiment, the horizontal movement of sliding plate 21 is scaled into the vertical movement of sliding block 22 by the second inclined plane 211 of sliding plate 21 and the first inclined plane 221 of sliding block 22, so that the vertical movement of sliding block 22 driving the workpiece can reach the precision of 1 microns, which ensures the precision of chamfering and improves the processing efficiency.

[0037] Specifically, the clamping assembly 1 is the basic part of the workpiece clamping, and the clamping cavity 10 is provided through the inside for firmly clamping the workpiece to be processed. The clamping cavity 10 needs to fully consider the shape and size of the workpiece, to ensure that the workpiece can be firmly fixed during processing, and to avoid the decline of processing precision due to unstable clamping. In addition, the clamping assembly 1 is particularly provided with an inclined surface 121 on the top of one side of the clamping cavity 10, which provides a precise processing reference surface for subsequent grinding operation, so that the grinding assembly 3 can better meet the chamfering requirements of the workpiece, thereby ensuring the uniformity and consistency of the chamfering.

[0038] Reference Figure 2The sliding assembly 2 is a key part for achieving high-precision vertical movement of the workpiece, which is composed of a sliding plate 21 and a sliding block 22. The sliding block 22 is located below the workpiece in the clamping cavity 10, and the bottom of the sliding block 22 is provided with a first inclined surface 221. The sliding plate 21 is located below the sliding block 22, and the top of the sliding plate 21 is provided with a second inclined surface 211 matched with the first inclined surface 221. The first inclined surface 221 and the second inclined surface 211 are matched with each other, so that the movement of the sliding plate 21 in the horizontal direction can be converted into the movement of the sliding block 22 in the vertical direction through the interaction of the first inclined surface 221 and the second inclined surface 211. When the sliding plate 21 moves horizontally, the sliding block 22 moves vertically along the direction of the second inclined surface 211, thereby driving the workpiece to achieve precise vertical displacement. Through the transmission relationship of the first inclined surface 221 and the second inclined surface 211, the vertical movement distance of the sliding block 22 is also proportionally reduced relative to the horizontal movement distance of the sliding plate 21. Specifically, even if the horizontal movement distance of the sliding plate 21 is large, the vertical movement distance of the workpiece can be accurately controlled within a very small range, for example, an accuracy of 1 micron can be achieved. This high-precision vertical movement capability provides extremely precise displacement control for chamfering, ensuring the accuracy and consistency of chamfering, and also greatly improving the processing efficiency. More specifically, the vertical height of the second inclined surface 211 gradually decreases or increases along the horizontal direction, and when the sliding plate 21 moves horizontally, the first inclined surface 221 of the sliding block 22 is adapted to slide from the bottom of the second inclined surface 211 to the top of the second inclined surface 211, so that the horizontal movement of the sliding plate 21 is proportionally scaled into the vertical movement of the sliding block 22. Through the inclination angle of the first inclined surface 221 and the second inclined surface 211, the vertical movement distance of the sliding block 22 is proportionally reduced relative to the horizontal movement distance of the sliding plate 21, which not only improves the accuracy of displacement control, but also reduces the dependence on high-precision driving devices through mechanical transmission, thereby reducing the cost. When the sliding plate 21 is subjected to a horizontal thrust, it can generate a vertical upward component force along the inclined surface direction. The inclination angle of the second inclined surface 211 is accurately calculated to ensure that the vertical displacement of the sliding block 22 can achieve extremely high precision when the sliding plate 21 moves horizontally, for example, to achieve 1 micron fine adjustment, which will not be described further herein. The second inclined surface 211 and the first inclined surface 221 form a stable contact and transmission relationship, and through the interaction of the inclined surfaces, the horizontal movement of the sliding plate 21 is converted into the vertical movement of the sliding block 22.

[0039] The grinding assembly 3 is directly involved in the chamfering process, which is slidably arranged on the inclined surface 121 of the clamping assembly 1 and grinds the part of the workpiece extending out of the clamping cavity 10. The grinding assembly 3 fully considers the contact mode with the workpiece and the grinding force, and through precise grinding action, it can efficiently remove the excess material on the edge of the workpiece to form a smooth chamfer that meets the design requirements. The grinding assembly 3 works with the sliding assembly 2, on the one hand, to realize the high-precision vertical movement of the workpiece through the sliding assembly 2, and on the other hand, to chamfer the workpiece through its own grinding action. The two work together to achieve efficient completion of high-precision chamfering.

[0040] It is worth noting that the mobile platform 4 is also included, which is suitable for driving the sliding plate 21 to move horizontally. The minimum scale of the existing integrated precision mobile platform 4 can only reach 0.01 mm. For the material of the ultrasonic transducer, if a micron-level chamfer is to be made, it exceeds the minimum scale of the mobile platform 4. Therefore, the sliding assembly 2 is used to make an equal proportion scaling of the moving distance of the precision mobile platform 4, for example, a 10:1 scaling. In this way, the mobile platform 4 moves one scale, and the sliding block 22 only rises by 1 micron. This is beyond the reach of manual naked eye and simple clamps, which not only ensures the accuracy of the chamfer but also improves the processing efficiency.

[0041] Further, the first magnetic member 212 is arranged in the sliding plate 21, which is suitable for magnetically attracting the sliding block 22, so that the first inclined surface 221 at the bottom of the sliding block 22 and the second inclined surface 211 at the top of the sliding plate 21 are always in contact.

[0042] In this embodiment, the sliding block 22 and the sliding plate 21 are always tightly attached through the magnetic attraction of the first magnetic member 212, eliminating the jumping error caused by sliding, making the relative sliding more smooth.

[0043] Specifically, the first magnetic member 212 firmly attracts the slider 22 through magnetic attraction, ensuring that the first inclined surface 221 at the bottom of the slider 22 is always in close contact with the second inclined surface 211 at the top of the slide plate 21. Due to the magnetic attraction of the first magnetic member 212, the contact between the slider 22 and the slide plate 21 is more stable, avoiding the slight bounce or vibration that may occur during sliding, thereby significantly improving the operation accuracy of the device. The magnetic attraction of the first magnetic member 212 not only ensures the stability of the contact, but also makes the relative sliding between the slider 22 and the slide plate 21 more smooth, reducing the jamming phenomenon caused by friction or poor contact. With the assistance of the first magnetic member 212, the slider 22 and the slide plate 21 can maintain high stability during long-term operation, reducing the risk of failure caused by mechanical wear or looseness, and reducing the dependence on complex mechanical locking devices, thereby reducing the overall complexity and manufacturing cost of the device. Therefore, the first magnetic member 212 not only improves the accuracy and efficiency of the sliding assembly 2, but also enhances the stability and reliability of its operation, providing a strong guarantee for high-precision machining. The first magnetic member 212 is preferably a strong magnet.

[0044] It is worth noting that lubricating liquid can also be provided between the slide plate 21 and the slider 22, i.e. the sliding contact parts of the slide plate 21 and the slider 22 are lubricated with lubricating oil to reduce the friction coefficient and make the relative sliding more smooth, and the bottom of the slide plate 21 is provided with an oil return groove to collect lubricating oil to ensure that the lubricating oil can be recycled, so that the sliding assembly 2 has the advantages of compact structure, small cumulative error, smooth movement, etc., and is suitable for mechanisms with high precision requirements.

[0045] Further, referring to Figure 4 The clamping assembly 1 includes a first clamping plate 11, a second clamping plate 12, and a first locking member 13. The first clamping plate 11 and the second clamping plate 12 are horizontally spaced apart and form a clamping cavity 10. The first locking member 13 is adapted to lock and connect the first clamping plate 11 and the second clamping plate 12 and drive the first clamping plate 11 and the second clamping plate 12 to move closer to or away from each other.

[0046] In this embodiment, the clamping assembly 1 realizes high-precision clamping and stable fixation of the workpiece through the cooperative action of the first clamping plate 11, the second clamping plate 12, and the first locking member 13, thereby improving the machining precision and enhancing the adaptability and operation convenience of the clamping assembly 1, providing an important guarantee for the overall performance of the chamfering device.

[0047] Specifically, the first clamping plate 11 and the second clamping plate 12 are the main components of the clamping assembly 1, which are horizontally spaced apart and together form a clamping cavity 10 for clamping the workpiece. The first clamping plate 11 and the second clamping plate 12 can flexibly adjust the size of the clamping cavity 10 according to the size and shape of the workpiece, ensuring that the workpiece can be stably clamped therein. The shape and size of the clamping cavity 10 can be optimized according to the characteristics of the workpiece to meet different machining requirements. The first locking member 13 is used to connect the first clamping plate 11 and the second clamping plate 12 and drive them to approach or move away from each other. By adjusting the first locking member 13, the first clamping plate 11 and the second clamping plate 12 can clamp or release the workpiece, ensuring that the workpiece remains stable during machining. Through precise control of the first locking member 13, the clamping assembly 1 can achieve high-precision clamping of the workpiece, ensuring that the workpiece remains stable during machining, thereby improving machining precision.

[0048] Notably, to further improve the stability of clamping, the inner surfaces of the first clamping plate 11 and the second clamping plate 12 can be designed to match the shape of the workpiece, such as an arc or a flat surface, to better fit the workpiece surface. In addition, the clamping plate surface can also be provided with anti-slip texture or coating to prevent the workpiece from slipping during clamping. The first locking member 13 can take various forms, such as a threaded locking member, a hydraulic locking member, a knurled screw, or a pneumatic locking member, and the appropriate locking method is selected according to different application scenarios to meet different machining requirements.

[0049] Further, the second clamping plate 12 is provided with an inclined surface 121 at the top, one end of the inclined surface 121 being close to the clamping cavity 10, and a guide groove 1211 is provided on the inclined surface 121. The grinding assembly 3 is slidingly arranged in the guide groove 1211, and a gap is left between the grinding assembly 3 and the inclined surface 121.

[0050] In this embodiment, by providing the guide groove 1211 on the inclined surface 121 and leaving a gap between the grinding assembly 3 and the inclined surface 121, not only is the inclined surface 121 effectively protected, but also the grinding precision and stability are improved, the maintenance cost is reduced, and the applicability and service life of the grinding assembly 3 are enhanced.

[0051] Specifically, a gap is left between the grinding assembly 3 and the inclined surface 121, so that the grinding assembly 3 does not directly contact the inclined surface 121 during sliding, which effectively avoids wear or scratches on the inclined surface 121 during movement of the grinding assembly 3, prolonging the service life of the grinding assembly 3 and the clamping assembly 1. More specifically, the grinding assembly 3 includes a collet 31 and a whetstone 32, the collet 31 is slidingly arranged in the guide groove 1211, and the whetstone 32 is fixedly arranged above the collet 31. The whetstone 32 is arranged in parallel with the inclined surface 121 and leaves a certain gap. The collet 31 is slidingly arranged in the guide groove 1211 on the top of the inclined surface 121 of the second clamping plate 12, which can ensure smooth sliding of the collet 31 in the guide groove 1211 and provide stable support for the whetstone 32. The whetstone 32 is fixedly arranged above the collet 31 and forms an integral structure with the collet 31. The material of the whetstone 32 can be selected according to the processing requirements, such as diamond, silicon carbide or aluminum oxide, etc. These materials have good wear resistance and grinding performance. The whetstone 32 is arranged in parallel with the inclined surface 121 and leaves a certain gap between them, which can avoid direct contact between the whetstone 32 and the inclined surface 121 during grinding, reducing the risk of wear and damage, thereby protecting the inclined surface 121 from wear or scratches. At the same time, since the whetstone 32 does not directly contact the inclined surface 121, the inclined surface 121 is less likely to accumulate grinding debris, reducing the grinding error caused by debris accumulation, and also facilitating cleaning and maintenance of the chamfering device, reducing the maintenance cost of the chamfering device. Moreover, the parallel arrangement of the whetstone 32 and the inclined surface 121 ensures uniform stress during workpiece grinding, avoiding grinding errors caused by uneven contact, and the sliding of the collet 31 in the guide groove 1211 further improves the stability of the grinding trajectory.

[0052] Further, the grinding assembly 3 further includes a second magnetic member arranged in the guide groove 1211 and adapted to magnetically connect the collet 31, so that the collet 31 tightly contacts the inclined surface 121.

[0053] In this embodiment, the second magnetic member further optimizes the contact and movement stability between the collet 31 and the inclined surface 121, and the contact between the collet 31 and the inclined surface 121 is more stable, and the grinding process is more smooth, thereby realizing high-precision and high-efficiency chamfering.

[0054] Specifically, the second magnetic member is arranged in the guide groove 1211, and its main function is to connect the chuck 31 through magnetism, ensuring that the chuck 31 is always in close contact with the inclined surface 121 during sliding. This magnetic connection not only enhances the stability of the contact between the chuck 31 and the inclined surface 121, but also avoids loosening of the chuck 31 due to mechanical vibration or external force. The second magnetic member ensures that the chuck 31 maintains close contact with the inclined surface 121 during sliding in the guide groove 1211 through magnetic attraction, which not only effectively eliminates the jumping error caused by sliding and ensures a smoother movement trajectory of the grinding assembly 3, but also avoids hard contact between the chuck 31 and the inclined surface 121, reducing surface damage caused by friction or collision. This protection mechanism not only prolongs the service life of the device, but also reduces maintenance costs. In summary, the second magnetic member makes the sliding of the chuck 31 on the inclined surface 121 smoother, reducing grinding errors caused by poor contact or vibration. At the same time, stable contact also improves grinding efficiency, ensuring the accuracy and consistency of chamfering.

[0055] Further, referring to Figure 3 It also includes a frame assembly 5, which includes a bottom plate 51, a side stand 52, and a beam plate 53. The sliding assembly 2 is horizontally arranged on the bottom plate 51, the beam plate 53 has a sliding hole vertically through it, and the sliding block 22 is vertically arranged in the sliding hole. The clamping assembly 1 is detachably mounted above the beam plate 53.

[0056] In this embodiment, the clamping assembly 1 is detachably mounted above the beam plate 53, allowing users to quickly assemble and disassemble the clamping assembly 1, making it easy to chamfer workpieces in different environments. It is suitable for scenarios that require frequent replacement of workpieces or adjustment of processing positions.

[0057] Specifically, the frame assembly 5 constitutes the support structure of the entire chamfering device. The sliding plate 21 is horizontally arranged on the moving platform 4, which is arranged on the bottom plate 51. The vertical position of the workpiece is adjusted by the horizontal sliding of the sliding plate 21 and the vertical movement of the sliding block 22. The beam plate 53 has a sliding hole vertically through it, and the sliding block 22 is vertically arranged in the sliding hole to control the vertical position of the workpiece. The horizontal sliding of the sliding plate 21 on the moving platform 4 and the vertical sliding of the sliding block 22 in the sliding hole allow the processing position of the workpiece to be flexibly adjusted as needed, which not only improves the applicability of the chamfering device, but also ensures the accuracy and stability of the chamfering process.

[0058] More specifically, the clamping assembly 1 is detachably mounted above the beam plate 53 by the second locking member 14, facilitating quick replacement and adjustment. The structure of the second locking member 14 includes but is not limited to knurled screws, which will not be further limited herein. The detachable mounting of the clamping assembly 1 on the beam plate 53 improves the flexibility of operation, allowing workers to quickly assemble and disassemble the workpiece, reducing the preparation time before and after processing, thereby significantly improving work efficiency, and is particularly suitable for small-batch, multi-variety production modes, and can quickly adapt to the processing needs of different workpieces.

[0059] Notably, the chamfering process can be performed after the workpiece is positioned. The detachable clamping assembly 1 facilitates the overall movement of the clamping assembly 1. If there are workpieces of different heights, only the wider sheet of the same thickness as the workpiece needs to be clamped in the clamping assembly 1, thereby raising the workpiece to be ground for grinding; and it is convenient for workers to chamfer the workpiece in different environments to prevent grinding dust from falling into the slide plate 21, thereby increasing the secondary damage to the slide plate 21, thereby ensuring its running accuracy and service life.

[0060] Further, the sliding assembly 2 further comprises a baffle 213, which is arranged at the top end of the slide plate 21, and the baffle 213 is adapted to abut against the slide block 22.

[0061] In this embodiment, the baffle 213 is arranged at the top end of the slide plate 21, and when the slide block 22 moves vertically in the sliding hole, the baffle 213 is adapted to abut against the bottom of the slide block 22, so that the slide block 22 can normally move vertically in the beam plate 53 of the frame assembly, and the baffle 213 plays a limiting role to prevent the slide block 22 from derailing. By limiting the horizontal movement of the slide block 22 through the contact between the bottom of the slide block 22 and the baffle 213, the vertical movement of the slide block 22 can be effectively guaranteed, thereby ensuring the movement accuracy of the slide block 22 in the vertical direction, and avoiding processing errors or device damage caused by the slide block 22 derailing. The main function of the baffle 213 is to limit the movement range of the slide block 22 and ensure the movement accuracy of the slide block 22 in the vertical direction.

[0062] Further, when operating the chamfering device, first, the workpiece is loaded into the clamping assembly 1, the first locking member 13 is not tightened temporarily, a small gap is left between the first clamping plate 11 and the second clamping plate 12, so that the workpiece can move up and down, the grinding assembly 3, the sliding assembly 2 and the frame assembly 5 are assembled, the workpiece is fastened by the first locking member 13, then the assembled clamping assembly 1 is fixed on the beam plate 53 of the frame assembly 5 through the second locking member 14, then the first locking member 13 and the second locking member 14 are loosened, and the leveling pretreatment (the way of placing the film) is performed, so as to ensure that the top of the workpiece is flush with the first clamping plate 11 (by placing the glass on the first clamping plate 11, if the top of the workpiece completely adheres to the glass, it is considered that the leveling is completed), then the second locking member 14 is locked, then the knob of the precision moving platform 4 is rotated, at this time, the moving platform 4 drives the sliding plate 21 to move horizontally, so that the sliding block 22 can move vertically and drive the workpiece to move up and down, until the workpiece is lifted to a specified distance, the workpiece is clamped by tightening the first locking member 13, finally, the workpiece can be chamfered by pushing the grinding assembly 3, or the second locking member 14 is loosened, and the clamping assembly 1 is moved to other places for chamfering.

[0063] It should be noted that the above embodiments can be freely combined as needed. The above is only the preferred embodiment of the present application, and it should be pointed out that for ordinary skilled in the art, without departing from the principles of the present application, a number of improvements and refinements can be made, which improvements and refinements should be considered as the protection scope of the present application.
