Description

Technical Field

[0001] This invention relates to the field of diamond composite sheet processing technology, and more specifically, to a processing apparatus for diamond composite sheets. Background Technology

[0002] Diamond composite sheets are widely used in superhard tools and cutting tools due to their superior hardness, wear resistance, and high-temperature performance. However, their high hardness and brittleness present numerous challenges during machining. To address these issues, modern machining equipment employs a variety of advanced technologies aimed at improving machining accuracy, efficiency, and material properties.

[0003] A search revealed a planar grinding device for processing diamond composite sheets with an adjustable grinding surface, as proposed in Chinese Patent (Announcement No.: CN207982964U). This device includes a base, a support rod, and a pillar. Fixed plates are fixed to the upper left and right sides of the base, and a first motor is mounted on the upper center of the fixed plates. A rotating rod is connected to the inner side of the first motor, and a movable rod is connected to the surface of the rotating rod. A crossbar is connected to the upper part of the pillar, and a fixed frame is fixed below the second motor. Threaded rods are arranged around the perimeter of the fixed frame, and a second fixed block is connected to the inner side of the threaded rods. The support rod and the movable seat are connected by fixing bolts. This planar grinding device for processing diamond composite sheets with an adjustable grinding surface features a movable seat and support rod bolted together, facilitating the rotation of the movable seat and thus easily adjusting the angle of the grinding stone. This allows the device to grind diamond composite sheets of different shapes, improving the grinding effect.

[0004] While the aforementioned patents can achieve the detection function, they still have the following shortcomings in actual use: In practical applications, the grinding precision of diamond composite sheets is affected by the grinding head and the pressure applied to it, and precise local machining is not possible. This may lead to reduced machining accuracy, uneven or rough surfaces, and affect overall performance. Secondly, the difficulty in local machining makes fine-tuning or detailed machining of specific areas difficult, especially in the manufacture of precision tools or micro-components. In addition, the high hardness of the material can cause uneven wear of the grinding head, reducing tool life and affecting machining stability. Machining efficiency may also be reduced because precise local control is not possible, requiring coverage of the entire surface and potentially increasing post-processing. Finally, the machining process may lead to material waste and increase production costs.

[0005] Therefore, we have made improvements and proposed a processing device for diamond composite sheets to solve the problems mentioned above. Summary of the Invention

[0017] In the scheme of this application: 1. By integrating a control module and a current regulator, the current intensity of each coil on the current regulator is individually controlled, thereby adjusting the fluidity of the magnetorheological fluid. This allows for adjustment of the fluid viscosity according to changes in the applied external electric field, achieving different grinding intensities. The viscosity of the magnetorheological fluid in different grinding areas can be individually controlled, enabling fine adjustments to different grinding areas as needed, avoiding over- or under-grinding, thus improving processing accuracy and surface smoothness. At the same time, individually adjusting the viscosity of the magnetorheological fluid can reduce material loss, improve processing efficiency, shorten the production cycle, and enhance the adaptability of the equipment, making it suitable for workpieces of different hardness and shape. 2. The magnetorheological fluid in the storage tank is drawn by the first delivery pump and delivered into the conical cavity. The first stirring frame drives the magnetorheological fluid to rotate rapidly within the conical cavity, separating large particles of impurities. This prevents large particles from affecting the polishing effect during the grinding process, effectively avoiding scratches or uneven wear on the diamond composite sheet caused by impurities, thus ensuring processing accuracy and surface quality. Simultaneously, impurity removal maintains the fluidity and viscosity stability of the magnetorheological fluid, making the polishing process smoother and more efficient, improving processing results, reducing material waste, and decreasing equipment and tool wear, thus extending service life. 3. The power generated by the rotating rod during centrifugal separation drives the second stirring rack at the top to rotate synchronously in the ceramic storage tank, thereby stirring the separated magnetorheological fluid to maintain its uniformity and ensure the fluidity and viscosity of the liquid, thus improving processing accuracy and stability, optimizing the processing effect of diamond composite sheets, reducing local wear and processing fluctuations, improving surface finish and consistency, and enhancing the repeatability of the processing process; 4. The power from the drive assembly is transmitted to the transmission assembly through the connecting assembly, thereby driving the clamping assembly to clamp and fix the diamond workpiece. The connection process can be controlled independently to ensure the stable fixation of the diamond composite sheet during processing, avoid workpiece loosening or positional displacement, improve processing accuracy and safety, and the clamping method can be flexibly adjusted according to the shape and requirements of different workpieces.

Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention. Example

[0021] Please see Figure 1-17This embodiment proposes a processing apparatus for diamond composite sheets, including a main frame 1, and further comprising: A three-way moving component is installed on the top wall of the main unit frame 1; The grinding motor 2 is mounted on the moving end of the three-way moving component, and the three-way moving component drives the grinding motor 2 to move in multiple directions. The grinding head 21 is detachably connected to the output end of the grinding motor 2. The grinding motor 2 drives the grinding head 21 to rotate. Its material is high-strength ceramic. A splash guard is installed on the bottom side wall of the grinding motor 2; The grinding barrel 3 is fixedly connected to the middle section of the top wall of the main frame 1; The liquid storage tank 31 is fixedly connected to the inside of the grinding barrel 3. It is filled with magnetorheological fluid as a grinding medium. The grinding barrel 3 and the liquid storage tank 31 are also made of high-strength ceramic to avoid affecting the magnetic field during the grinding process. The conveying groove 32 is located on one side of the bottom of the grinding barrel 3; An electromagnetic coil array 42 is fixedly connected to the inside of the grinding barrel 3. Each coil can adjust its current individually, thereby generating a programmable, non-uniform magnetic field distribution in the lower space inside the cavity. The control component, located on the inner top wall of the main frame 1, is used to individually control the current on the electromagnetic coil array 42, and to control the viscosity, rheological properties, and even the shape and hardness of the effective polishing area of ​​the magnetorheological fluid. Fixed plate 5 is located at the bottom of the middle section of the control module; The drive assembly is located on the outside of the fixed plate 5; Driven gear 54 is located on one side of the drive assembly and is connected to the drive end of the drive assembly; The connecting component is located inside the driven gear 54; Limit bracket 611 is located on one side of the bottom of the drive assembly; The transmission assembly is mounted on the limit frame 611; The first transmission rod 64 is disposed on the transmission end of the transmission assembly. It is connected to the drive assembly and the transmission assembly through the connecting assembly, so that the drive assembly drives the first transmission rod 64 to move up and down. The clamping assembly is located in the middle of the inner side of the liquid storage tank 31 and is at the same height as the electromagnetic coil array 42. The driven end of the clamping assembly is connected to the first transmission rod 64, and the clamping assembly is driven to run through the first transmission rod 64. The diamond workpiece 610 is disposed inside the clamping end of the clamping assembly, clamped and fixed by the clamping assembly, and in contact with the grinding head 21. The grinding head 21 grinds the diamond workpiece 610.

[0022] like Figure 1-17As shown, in a preferred embodiment, based on the above method, the three-way moving assembly further includes two sets of Z-axis lead screw slides 11 fixedly connected to the top wall of the main frame 1. The Z-axis lead screw slides 11 are symmetrically distributed about the central axis of the main frame 1. The moving end of the Z-axis lead screw slide 11 is fixedly connected to an X-axis lead screw slide 12. The moving end of the X-axis lead screw slide 12 is fixedly connected to a Y-axis lead screw slide 13. The moving end of the Y-axis lead screw slide 13 is detachably connected to the grinding motor 2. The two sets of Z-axis lead screw slides 11 are operated under unified control through a control component to achieve precise synchronization. The Z-axis lead screw slide 11 drives the top X-axis lead screw slide 12 to move along the Z-axis, while the X-axis lead screw slide 12 drives the top Y-axis lead screw slide 13 to move along the X-axis. The Y-axis lead screw slide 13 drives the grinding motor 2 to move along the Y-axis. This allows for free adjustment of the horizontal position and vertical height of the grinding motor 2, which can better adapt to grinding needs. Furthermore, the grinding pressure and grinding position can be flexibly adjusted as needed during the grinding process.

[0023] The splash-proof assembly includes a limiting sleeve 22 fixedly connected to the bottom side wall of the grinding motor 2. A spring 23 is fixedly connected to the top inner wall of the limiting sleeve 22. A limiting ring 24 that slides inside the limiting sleeve 22 is fixedly connected to the bottom end of the spring 23. A first connecting rod 25 is fixedly connected to the inner wall of the limiting ring 24. The first connecting rod 25 is rotatably connected to the grinding head 21. A sealing plate 26 is fixedly connected to the bottom end of the first connecting rod 25. The size of the sealing plate 26 is larger than the diameter of the liquid storage tank 31. As the grinding motor 2 drives the grinding head 21 to move into the grinding barrel 3, it drives the sealing plate 26 to move down synchronously and fit against the top wall of the grinding barrel 3, thereby sealing the opening at the top of the grinding barrel 3 and preventing the magnetorheological fluid from splashing during the grinding process. By compressing the spring 23, the grinding head 21 can continue to move down a certain distance after the sealing plate 26 fits against the grinding barrel 3.

[0024] The control components include an integrated control module 4 fixedly connected to the inner top wall of the main frame 1. A current regulator 41 is fixedly connected to one side of the integrated control module 4. The current regulator 41 is electrically connected to the electromagnetic coil array 42. Through the cooperation of the integrated control module 4 and the current regulator 41 (the integrated control module 4 and the current regulator 41 are existing technologies, and will not be described in detail, referring to existing integrated control modules and current regulators, and the integrated control module uses an existing commercial control system to control the equipment), the current of each coil on the electromagnetic coil array 42 can be precisely controlled, thereby controlling the viscosity and hardness of the magnetorheological fluid at the contact position between the grinding head 21 and the diamond workpiece 610. At the same time, the integrated control module 4 integrates sensors (pressure, flow, and temperature sensors), a communication module, a signal processing unit, and other control components for overall control of the equipment operation. The sensors are also installed at various points on the equipment for real-time monitoring of the equipment's operating status.

[0025] The drive assembly includes a drive motor 51 fixedly connected to the outer wall of the fixed plate 5 away from the current regulator 41, and a limiting frame 53 fixedly connected to the outer wall of the fixed plate 5 near the current regulator 41.

The driven gear 54 meshes with the limiting frame 53. The drive motor 51 drives the drive gear 52 to rotate, and at the same time, the drive gear 52 drives the driven gear 54 to rotate inside the limit frame 53.

[0026] The connecting assembly includes a fixed frame 55 fixedly connected to the outer wall of the fixed plate 5 on the side away from the current regulator 41, an electric push rod 56 fixedly connected to the inner side of the fixed frame 55, a first hexagonal rod 57 rotatably connected to the output end of the electric push rod 56, and a connecting toothed disc 58 fixedly connected to the end of the first hexagonal rod 57. The electric push rod 56 drives the connecting gear plate 58 to move laterally via the first hexagonal rod 57. At the same time, the first hexagonal rod 57 passes through the limiting frame 53 and the driven gear 54, so that the first hexagonal rod 57 rotates synchronously during the rotation of the driven gear 54, and the connecting gear plate 58 rotates synchronously through the first hexagonal rod 57. During the rotation, the sliding of the first hexagonal rod 57 inside the limiting frame 53 and the driven gear 54 is not affected.

[0027] The transmission assembly includes a worm 6 rotatably connected to the inside of one side of the limiting frame 611. A limiting gear 59 is fixedly connected to one end of the worm 6 near the connecting gear 58. The limiting gear 59 is engaged with the connecting gear 58. A worm wheel 61 rotatably connected to one side of the worm 6 is engaged with the inside of the limiting frame 611. A threaded sleeve 62 is fixedly connected to the top of the worm wheel 61. A drive screw 63 is threadedly connected to the inside of the threaded sleeve 62. The top of the drive screw 63 is fixedly connected to the bottom of the first transmission rod 64. After the electric push rod 56 pushes the connecting gear plate 58 and the limiting gear plate 59 to engage with each other via the first hexagonal rod 57, the driven gear 54 drives the limiting gear plate 59 to rotate synchronously via the first hexagonal rod 57 and the connecting gear plate 58. The limiting gear plate 59 drives the worm gear 6 to rotate, which in turn drives the worm wheel 61 to rotate. During this process, the worm wheel 61 drives the threaded sleeve 62 at the top to rotate synchronously, thereby driving the drive screw 63 to rise and fall (the top of the first transmission rod 64 at the top of the drive screw 63 is limited by the second hexagonal rod 65 at the top, so it can only rise and fall vertically and cannot rotate, as mentioned below).

[0028] The clamping assembly includes a placement platform 69 fixedly connected to the middle section of the inner side of the liquid storage tank 31. The placement platform 69 is engaged with the diamond workpiece 610. Three clamping arms 68 are rotatably connected to the outer side of the placement platform 69. A second transmission rod 67 is rotatably connected to the bottom end of the clamping arm 68. A fixed sleeve 66 is rotatably connected to the bottom end of the second transmission rod 67. The fixed sleeve 66 is fixedly connected to the top end of the first transmission rod 64. A second hexagonal rod 65 is fixedly connected to the middle section of the bottom wall of the placement platform 69. The second hexagonal rod 65 is slidably connected to the first transmission rod 64. The second hexagonal rod 65 at the bottom of the placement platform 69 limits the top end of the first transmission rod 64, so that when the threaded sleeve 62 rotates outside the drive screw 63, it will drive the top first transmission rod 64 to rise and fall synchronously. The rise and fall of the first transmission rod 64, through the second hexagonal rod 65 and the fixed sleeve 66, drives the bottom end of the second transmission rod 67 on the outside to rise and fall synchronously. Then, the transmission of the second transmission rod 67 pushes the bottom end of the clamping arm 68 outward at the same time, so that the top end of the clamping arm 68 rotates inward, clamping and fixing the diamond workpiece 610.

The magnetorheological fluid in the storage tank 31 is extracted by the first transfer pump 81 through the transfer tank 32 and the first connecting pipe 8, and then transported into the conical cavity 84 through the second connecting pipe 82. Large particles of impurities inside are centrifuged and separated, and the impurities gather at the bottom of the conical cavity 84. The magnetorheological fluid is then extracted by the third transfer pump 10 and transported into the ceramic storage tank 101 for storage. At the same time, the stored magnetorheological fluid can be extracted by the fourth transfer pump 104 and transported back to the storage tank 31 through the fifth connecting pipe 105 to replenish the magnetorheological fluid in the storage tank 31. The impurities that accumulate at the bottom of the conical cavity 84 are extracted by the second delivery pump 91 through the third connecting pipe 9 and transported into the storage chamber 93 through the fourth connecting pipe 92 for storage. At the same time, the magnetorheological fluid containing large-angle impurities can be discharged through the drain port 94.

A second sprocket 71 is provided on the rotating end of the first sprocket 7 away from the drive motor 51. The rotating end of the second sprocket 71 near the first sprocket 7 is fixedly connected to the rotating end of the first sprocket 7 away from the drive motor 51. At the same time, the rotating end of the second sprocket 71 near the first sprocket 7 and the rotating end of the first sprocket 7 away from the drive motor 51 are rotatably connected to the side wall of the fixing plate 5. A third transmission rod 72 rotating inside the ceramic separation cylinder 83 is fixedly connected to the rotating end of the second sprocket 71 away from the first sprocket 7. The inner side of the third transmission rod 72... A first bevel gear 73 is fixedly connected to the end and rotates inside the ceramic separation cylinder 83. A second bevel gear 74 is meshed with the top of the first bevel gear 73 and rotates inside the ceramic separation cylinder 83. The second bevel gear 74 is rotatably connected to the third connecting pipe 9. A feeding sleeve 75 is fixedly connected to the top of the second bevel gear 74. Multiple through holes are opened on the side wall of the feeding sleeve 75. A rotating rod 76 is fixedly connected to the top of the feeding sleeve 75. A first stirring frame 77 is fixedly connected to the bottom outer wall of the rotating rod 76. The first stirring frame 77 is located in the middle section inside the conical cavity 84. A second stirring frame 78 is fixedly connected to the outer side of the top of the rotating rod 76. The second stirring frame 78 is located inside the ceramic storage tank 101. While the driving gear 52 drives the driven gear 54 to rotate, it also drives the first sprocket 7 to rotate. The first sprocket 7, through the second sprocket 71, drives the third transmission rod 72 and the first bevel gear 73 inside the ceramic separation cylinder 83 to rotate synchronously. Then, the first bevel gear 73 drives the second bevel gear 74 at the top to rotate. During the rotation of the second bevel gear 74, the top feeding sleeve 75, the rotating rod 76, the first stirring frame 77, and the second stirring frame 78 also rotate synchronously. Thus, while the first stirring frame 77 drives the magnetorheological fluid inside the conical cavity 84 to rotate, the second stirring frame 78 also stirs the magnetorheological fluid at the top.

[0031] Specifically, the processing equipment for this diamond composite sheet is used as follows: First, the diamond workpiece 610 is placed on top of the placement stage 69. Then, the electric push rod 56 pushes the first hexagonal rod 57 and the connecting gear 58 towards the limiting gear 59, causing the connecting gear 58 and the limiting gear 59 to engage. Then, the drive motor 51 drives the driving gear 52 to rotate, which in turn drives the driven gear 54 to rotate synchronously. The driven gear 54 then drives the first hexagonal rod 57 to rotate, thereby driving the connecting gear 58, the limiting gear 59, and the worm gear 6 to rotate synchronously. Finally, the worm gear 6... The rod 6 uses the worm gear 61 to drive the threaded sleeve 62 to rotate, thereby lifting the drive screw 63 inside the threaded sleeve 62. During the process, the drive screw 63 uses the first transmission rod 64 and the fixed sleeve 66 to drive the bottom end of the second transmission rod 67 to move upward synchronously, thereby supporting the bottom end of the clamping arm 68 to the top, while the top end of the clamping arm 68 rotates inward to achieve clamping and fixing of the diamond workpiece 610. Afterward, the electric push rod 56 drives the first hexagonal rod 57 and the connecting gear plate 58 to move to the side of the electric push rod 56, so that the connecting gear plate 58 and the limiting gear plate 59 are disconnected. Then, the top X-axis lead screw slide 12 is moved along the Z-axis by the Z-axis lead screw slide 11, and the top Y-axis lead screw slide 13 is moved along the X-axis by the X-axis lead screw slide 12. The grinding motor 2 is moved along the Y-axis by the Y-axis lead screw slide 13, thereby moving the grinding motor 2 directly above the grinding barrel 3 and inserting the grinding head 21 into the liquid storage tank 31, where it comes into contact with the top wall of the diamond workpiece 610. During the descent of the grinding motor 2, the sealing plate 26 is driven to descend synchronously, sealing the opening at the top of the grinding barrel 3 to prevent the magnetorheological fluid from splashing during the grinding process. Then, the magnetorheological fluid inside the ceramic storage tank 101 is extracted by the fourth delivery pump 104 and transported into the storage chamber 31 through the fifth connecting pipe 105 to fill the space inside the storage chamber 31. After that, the grinding motor 2 starts to work, driving the grinding head 21 to rotate on the top wall of the diamond workpiece 610, thereby grinding the diamond workpiece 610. During the grinding process, the current on the electromagnetic coil array 42 is precisely controlled by the current regulator 41, thereby controlling the viscosity and hardness of the magnetorheological fluid in the grinding area, and thus precisely controlling the grinding effect. During the grinding process, the drive motor 51 continuously drives the drive gear 52 to rotate, and the drive gear 52 drives the first sprocket 7 to rotate. The first sprocket 7 then drives the first bevel gear 73 to rotate synchronously through the second sprocket 71 and the third transmission rod 72. After that, the first bevel gear 73 drives the top second bevel gear 74, the feeding sleeve 75, the rotating rod 76, the first stirring frame 77, and the second stirring frame 78 to rotate synchronously and rapidly. During the process, the magnetorheological fluid in the storage tank 31 is extracted by the first transfer pump 81 through the first connecting pipe 8 and the transfer tank 32, and then transported into the conical cavity 84 through the second connecting pipe 82. The magnetorheological fluid is stirred by the first stirring rack 77 to generate eddies, thereby using centrifugal force to throw large particles of impurities in the magnetorheological fluid to the outside and collect at the bottom of the conical cavity 84. The magnetorheological fluid is then extracted by the third transfer pump 10 and transported back to the ceramic storage tank 101 for further storage to replenish the magnetorheological fluid in the storage tank 31. The impurities are extracted by the second transfer pump 91 through the third connecting pipe 9 through the through hole in the side wall of the discharge sleeve 75 and transported into the fourth connecting pipe 92. Then, the impurities are transported into the storage tank 93 for storage through the fourth connecting pipe 92.
