Description

Technical Field

[0001] This invention belongs to the field of grinding technology, specifically relating to an ultrasonic-laser synergistic grinding wheel dressing device and method. Background Technology

[0002] With the continuous development of demands and technologies in various fields such as aerospace, automotive, shipbuilding, and major national equipment, the demand for high-temperature brittle and hard materials such as nickel-based superalloys, silicon nitride ceramics, and reaction-bonded silicon carbide composites (RB-SiC) is also increasing. Furthermore, due to the increasing complexity of the required functions, the shapes and precision required for processing these materials are becoming increasingly complex. Therefore, laser-assisted or ultrasonic-assisted grinding is often used in the mechanical manufacturing field to achieve the desired processing parameters. Although there are various auxiliary processing methods, they cannot be separated from grinding itself. Therefore, the problem of reduced processing efficiency due to wheel clogging, dulling, and ablation is a problem that must be solved during the processing. This necessitates frequent dressing and sharpening of the grinding wheel. Since diamond grinding wheels are often used when processing superhard materials such as RB-SiC, their high bonding strength and high abrasive hardness make dressing them difficult, inefficient, and time-consuming. Therefore, for the ultra-precision, high-efficiency and automation of grinding processes, it is essential to develop a high-speed and high-efficiency precision online dressing technology and device for diamond grinding wheels.

[0003] Currently, commonly used grinding wheel dressing methods in the industrial field mainly include traditional methods (including cup-shaped grinding wheel dressing, diamond pen dressing, etc.), electrolytic online grinding wheel dressing technology (ELID), electrical discharge dressing, ultrasonic vibration dressing, and laser dressing, such as the Chinese patent "A device for laser dressing and shaping grinding wheels based on visual inspection and its dressing method" (authorization number CN 108747825B). This method is based on visual inspection to extract and provide feedback on the contour shape of the laser-dressed grinding wheel in real time, which facilitates the computer to compensate for the correction path in real time. However, when laser dressing grinding wheels, the residual and adhered debris generated on the grinding wheel surface is difficult to remove. Even with real-time feedback, multiple dressings still cannot remove the residual debris, which will accumulate more and more. As a result, the shaping effect is good, but the sharpness cannot be restored, and the dressing purpose cannot be achieved well. There are also composite dressing methods that combine multiple techniques, such as ultrasonic vibration-assisted ELID dressing, as exemplified by the Chinese patent "Ultrasonic ELID Composite Surface Grinding System for Improving Oxide Film Quality" (authorization number CN 205497131 U). However, ELID dressing equipment is very complex and inconvenient to operate, and it can only dress metal-bonded grinding wheels, making it unsuitable for many situations. In addition, there are methods that combine ultrasonic vibration with traditional techniques, such as "Ultrasonic-Assisted Diamond Pendant Grinding Wheel Dressing Device" and "Ultrasonic Vibration Cup-Shaped Grinding Wheel Dresser for Dressing Superhard Abrasive Grinding Wheels" (authorization numbers CN 213765434 U and CN 205520952 U). However, the diamond pen and diamond grinding wheel cannot simultaneously perform shaping and sharpening work, resulting in a less sharp grinding wheel after dressing and low efficiency.

[0004] In summary, existing dressing devices for superhard abrasive forming grinding wheels have many limitations, and the existing composite dressing methods are also unable to fully utilize their respective advantages to achieve satisfactory dressing results. Summary of the Invention

[0005] The purpose of this invention is to provide an ultrasonic-laser synergistic grinding wheel dressing device and method to solve the problems mentioned in the background art.

[0006] The technical means employed in this invention are as follows:

[0007] An ultrasonic-laser coordinated grinding wheel dressing device includes: a servo motor, a three-dimensional moving stage, a laser ablation head, a shaped grinding wheel, a CCD camera, an image acquisition card, a computer, and an ultrasonic clamping device for the grinding wheel. The servo motor is connected to the ultrasonic clamping device and drives the ultrasonic clamping device and the shaped grinding wheel clamped on it to rotate. The ultrasonic clamping device includes several ultrasonic amplitude transformers, which amplify the amplitude and act as chucks that directly contact the workpiece. The CCD camera is placed on one horizontal side of the shaped grinding wheel, with a backlight positioned opposite it. The CCD camera and backlight are located on both sides of the shaped grinding wheel. The CCD camera is connected to the image acquisition card via a cable, and then connected to the computer via another cable. The laser ablation head is mounted and fixed on the three-dimensional moving stage, arranged horizontally along the tangential direction on one side of the shaped grinding wheel. The three-dimensional moving stage is connected to the computer via a cable, enabling controllable movement of the laser ablation head along the x, y, and z directions.

[0008] Furthermore, the ultrasonic clamping device for grinding wheels includes a four-jaw chuck body, four flange support jaws, four sets of ultrasonic amplitude transformers, and an ultrasonic transducer. The ultrasonic amplitude transformers are connected to the flange support jaws via flanges. The piezoelectric ceramic ultrasonic transducer is connected to the input end of the ultrasonic amplitude transformer via a double-ended stud. The flange support jaws are connected to the jaw chuck body via lead screws. The output ends of the four composite conical amplitude transformers directly serve as clamps that contact the workpiece. The forming grinding wheel is clamped by the ultrasonic clamping device and mounted on the worktable together with a servo motor. The rotation of the ultrasonic clamping device and the forming grinding wheel is achieved by the servo motor.

[0009] Furthermore, the four-jaw chuck body engages with the ultrasonic chuck chuck chuck through the Archimedes spiral groove on the internal bevel gear disc. The ultrasonic chuck chuck has a structure that is symmetrically distributed in a cross shape in three-dimensional space.

[0010] Furthermore, the ultrasonic chuck head transmission part is provided with a planar thread, the upper part of the chuck is a tubular structure with a through hole, the front part of the tube is provided with a flange, and the flange of the ultrasonic amplitude transformer is fixed to the chuck by bolts; the ultrasonic amplitude transformer is a composite conical amplitude transformer with a cylindrical input, the end face of the input end is provided with a threaded hole, which is connected to the ultrasonic transducer, and a flange with circumferentially distributed through holes is provided at the vibration node.

[0011] This invention also discloses an ultrasonic-laser synergistic grinding wheel dressing method, which includes the following steps:

[0012] Step 1: Clamp the forming grinding wheel on the ultrasonic clamping device, fix it on the three-dimensional worktable, and connect it to the servo motor.

[0013] Step 2: Start the servo motor and control the clamping device to drive the grinding wheel to rotate at the given speed. The preset speed is set to 10 r / min. Turn on the backlight and image acquisition device to acquire the contour surface image of the grinding wheel and transmit it to the computer.

[0014] Step 3: The computer begins to process the edge contour information of the forming grinding wheel, compares the grinding wheel contour shape optimized according to the grinding wheel working requirements with the type and requirements of the grinding wheel surface texture to be processed, calculates the error margin of the forming grinding wheel to be dressed, and generates corresponding digital control instructions.

[0015] Step 4: The computer manipulates the three-dimensional moving stage to move the laser ablation head along the given trajectory in the x, y, and z directions. The laser ablation head is started and works according to the given processing parameters. At the same time, the ultrasonic transducer starts working and provides one-dimensional or two-dimensional ultrasonic vibration to the forming grinding wheel as required, so as to jointly realize the forming and dressing process of the forming grinding wheel.

[0016] Step 5: The image acquisition device acquires images of the machining quality of the grinding wheel surface during the dressing process and transmits them to the computer. Based on the feedback from the image acquisition device regarding the adhesion and residue of debris on the machining surface, the computer outputs control commands in real time, adjusts variables such as the frequency and amplitude of the ultrasonic transducer output, optimizes ultrasonic vibration parameters, and removes as much debris as possible generated during the laser dressing process.

[0017] Step Six: The computer again uses a CCD camera to photograph the surface of the shaped grinding wheel and determines whether the surface quality of the shaped grinding wheel after dressing is qualified and whether the residual debris meets the requirements. If it does not meet the requirements, the computer outputs the corresponding digital control signal to control the laser ablation head to complete the next stage of the laser dressing process until the shaped grinding wheel reaches the specified geometric accuracy and sharpness, thus completing the dressing of the shaped grinding wheel.

[0018] Step 7: Turn off the device and remove the compliant forming grinding wheel.

[0019] Compared with the prior art, the beneficial effects of the present invention are:

[0020] (1) Combining ultrasonic vibration with laser dressing technology effectively solves the problems of chip adhesion and consolidation during laser dressing of the forming grinding wheel, thus improving the processing quality.

[0021] (2) By combining CCD camera image acquisition with ultrasonic vibration, the residual status of grinding wheel surface debris during the processing is fed back in real time, which facilitates real-time adjustment and optimization of the output processing parameters, improves the removal rate of grinding wheel surface debris, and further improves the shaping and sharpening quality of grinding wheel.

[0022] (3) In addition to the traditional requirements for shaping and sharpening, the processing of the grinding wheel profile and surface texture has been introduced, which not only ensures the dressing accuracy of the grinding wheel, but also improves the processing capability of the grinding wheel.

[0023] (4) The amplitude rod is directly used as the chuck of the four-jaw chuck, which simplifies the structure of the device. While ensuring that controllable two-dimensional ultrasonic vibration can be provided, it is convenient to build the clamping device and the dressing equipment, saving material resources.

[0024] (5) The repair device has a simple structure, a compact repair method, and a wide range of applications, making it easy to carry out and implement in various task requirements and occasions. Attached Figure Description

[0040] The four-jaw self-centering chuck body 4 is connected to the ultrasonic chuck chuck clamps 3-1, 3-2, 3-3, and 3-4 via four grooves on its surface and bevel gears with an Archimedean spiral inside. Ultrasonic amplitude transformers 2-1, 2-2, 2-3, and 2-4 are connected to the ultrasonic chuck clamps via flanges. Four piezoelectric ceramic ultrasonic transducers 1-1, 1-2, 1-3, and 1-4 are connected to the input ends of the ultrasonic amplitude transformers 2-1, 2-2, 2-3, and 2-4 via double-ended studs. The chuck body is fixed to the servo motor's rotary shaft.

[0041] Figure 2 yes Figure 1 A schematic diagram of a mid-sonic amplitude transformer is shown below. Figure 2 As shown, the ultrasonic amplitude transformers 2-1, 2-2, 2-3, and 2-4 are composite conical amplitude transformers, meaning their output end 7 is conical, and their input end 5 has a threaded hole. The input end 5 is a cylinder with a slot. The amplitude transformers and the ultrasonic transducer are connected by bolt heads, which allows for easy tightening during manual installation. A flange 6 is located at the vibration node, with six through holes evenly distributed around its circumference. The output ends of the four composite conical amplitude transformers directly serve as clamps for contacting the workpiece, ensuring controllable two-dimensional ultrasonic vibration while facilitating the setup of clamping and dressing devices, thus saving resources.

[0042] Figure 3 yes Figure 1 A schematic diagram of the ultrasonic chuck collet is shown below. Figure 3 As shown, the bottom transmission part of the chuck is provided with a planar thread for meshing with the Archimedean spiral groove on the upper part of the large bevel gear disk inside the four-jaw chuck body, so as to realize forward and backward movement along the axial direction, thereby clamping or releasing the workpiece; the upper part of the chuck is a tubular structure with a through hole for supporting the input end of the ultrasonic amplitude transformer and the piezoelectric ceramic ultrasonic transducer. The front of the tube is provided with a flange for fixing with the flange of the ultrasonic amplitude transformer.

[0043] Figure 4 This invention describes an ultrasonic-laser synergistic grinding wheel dressing device, such as... Figure 4 As shown, it includes a servo motor 8, an ultrasonic clamping device for a grinding wheel 9, a forming grinding wheel 10, a CCD camera 11, a laser ablation head 12, a three-dimensional moving stage 13, a fiber laser 14, an image acquisition card 15, a backlight 16, and a computer 17.

[0044] like Figure 5 As shown, the operating procedures of the ultrasonic-laser synergistic grinding wheel dressing device described above are as follows:

[0045] The four piezoelectric ceramic ultrasonic transducers 1-1, 1-2, 1-3, and 1-4, and the four ultrasonic amplitude rods 2-1, 2-2, 2-3, and 2-4 have the same resonant frequency. The four piezoelectric ceramic ultrasonic transducers 1-1, 1-2, 1-3, and 1-4 are excited by the same ultrasonic power supply.

[0046] The forming grinding wheel 10 is clamped on the grinding wheel ultrasonic clamping device 9. The grinding wheel ultrasonic clamping device 9 is connected to the servo motor 8. The servo motor 8 drives the grinding wheel ultrasonic clamping device 9 and the forming grinding wheel 10 clamped on it to rotate. The servo motor 8 is connected to the computer 17 through a cable. The computer 17 controls the servo motor 10.

[0047] The CCD camera 11 is placed on one side of the forming grinding wheel 10 at a horizontal position. The backlight 16 is placed opposite the CCD camera 11, so that the CCD camera 11 and the backlight 16 are located on both sides of the forming grinding wheel 10. The CCD camera 11 is connected to the image acquisition card 15 through a cable, and then connected to the computer 17 through a cable.

[0048] Computer 17 starts servo motor 8, driving the ultrasonic clamping device 9 and the forming grinding wheel 10 to rotate at a given speed. It also starts backlight 16 and CCD camera 11 to capture the contour features and surface morphology of the forming grinding wheel 10, and transmits the images back to computer 17 via image acquisition card 15. Computer 17 processes the edge contour morphology information of the forming grinding wheel 10, compares the optimally designed grinding wheel contour shape with the required surface texture of the grinding wheel, calculates the processing parameters, performs real-time compensation, automatically plans the laser ablation head 12 to adjust the motion trajectory of the forming grinding wheel 10, and generates corresponding digital control commands.

[0049] The laser ablation head 12 is fixed on the three-dimensional worktable 13 and placed on the horizontal side of the forming grinding wheel 10. The laser ablation head is connected to the fiber laser 14. The fiber laser 14 and the three-dimensional worktable 13 are respectively connected to the computer 17 through cables. The computer 17 outputs instructions to realize the joint control of the three-dimensional worktable 13 and the laser ablation head 12 for laser trimming.

[0050] Computer 17 manipulates the three-dimensional moving stage 13 to make the laser ablation head 12 move along the given trajectory in the x, y, and z directions. The laser ablation head 12 is started and works according to the given processing parameters. The ultrasonic power supply is turned on, and the four ultrasonic transducers 1-1, 1-2, 1-3, and 1-4 start working, generating ultrasonic vibrations with the same frequency and amplitude but opposite vibration directions. The amplitude is amplified by the ultrasonic amplitude transformers 2-1, 2-2, 2-3, and 2-4, which in turn drive the forming grinding wheel 10 to perform one-dimensional or two-dimensional ultrasonic vibrations as required, so as to jointly realize the forming and finishing process and surface texture processing of the forming grinding wheel.

[0051] The CCD camera 11 continuously acquires images of the processing quality of the surface processed by the forming grinding wheel 10 during the finishing process and transmits them to the image acquisition card 15. The computer 17 outputs control commands in real time based on the information on the adhesion and residue of the processed surface fed back by the image acquisition card 15, and adjusts the frequency and amplitude of the ultrasonic transducers 1-1, 1-2, 1-3, and 1-4 to optimize the ultrasonic vibration parameters and remove as much debris as possible generated during the laser finishing process.

[0052] Computer 17 restarts servo motor 8, backlight 16, and CCD camera 11 to capture the contour and surface morphology of the shaped grinding wheel 10, and determines whether the contour, debris removal, and surface texture processing quality of the shaped grinding wheel 10 after dressing are up to standard. If the requirements are not met, the corresponding digital control signals are output again to control the three-dimensional worktable 13 and laser ablation head 12 to complete the next stage of laser dressing process until the shaped grinding wheel 10 meets the specified requirements, and finally the dressing of the shaped grinding wheel 10 is completed.

[0053] Close the experimental setup and remove the forming grinding wheel 10 that meets the composite dressing requirements.

[0054] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, and not to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention.
