Description

Technical Field

[0001] The invention relates to the technical field of abrasive jet polishing processing, and more particularly to a scale-adjustable ultrasonic-assisted rotating linear jet polishing device. Background Art

[0002] Currently, contact polishing methods for complex parts require the polishing tool to be smaller than the surface being machined. This poses challenges in maintaining stability during the polishing process. Furthermore, wear of the micro-polishing head can lead to surface accuracy issues. As the advantages of fluid polishing for precision polishing of complex surfaces become increasingly apparent, fluid polishing tools have been extensively researched. These complex surfaces, often composed of a combination of surfaces with varying curvatures, are designed to achieve specific mathematical features with high precision and meet both functional and aesthetic requirements. These surfaces include aspheric, free-form, and contoured surfaces. These surfaces play a central role in critical components in a wide range of fields, including aerospace, astronomical observation, marine equipment, automotive parts, mold manufacturing, and biomedical implants. Fluid polishing methods utilize a highly flexible fluid as the abrasive driving medium, effectively preventing damage to the workpiece caused by the hard intrusion of the abrasive. Furthermore, the fluid's morphology allows for contoured polishing of complex free-form surfaces. Faced with the growing demand for complex curved parts and the ever-increasing performance standards, traditional fluid polishing technologies are unable to meet the demands for efficient machining.

[0003] In order to improve the polishing efficiency of abrasive jets on parts, multi-nozzle abrasive water jets have begun to be widely used, mainly in parallel or converging nozzle designs. Parallel multi-nozzles are suitable for large-area processing, while converging multi-nozzles are suitable for high-precision polishing. When the abrasive flow inlet pressure is unstable, the interference of the jet beams between the multiple nozzle holes causes the material removal function to deviate from the ideal state, deteriorating the surface quality of the workpiece. Later, the invention patent with patent number CN202010989012.7 proposed a fluid line jet polishing device and its application method. The polishing device ejects a high-pressure and high-speed linear jet of fluid at the outlet. This method increases the polishing area while maintaining surface integrity. At the same time, the jet beam is stable, which can greatly improve the polishing efficiency and quality of fluid jet polishing. However, the device does not have ultrasonic energy field to assist in polishing, and the line jet nozzle is not adjustable.

[0004] Ultrasonic energy field assistance is widely considered to be one of the key methods to improve the efficiency of jet polishing. Compared with traditional jet polishing without ultrasonic assistance, ultrasonic pulse jet polishing can significantly improve efficiency. Under the action of the ultrasonic field, the abrasive flow ejected from the nozzle produces a pulse effect, and its impact kinetic energy is significantly enhanced, thereby achieving efficient polishing. Ultrasonic assisted polishing tools are mostly designed for single-nozzle or multi-nozzle polishing. Although it can improve efficiency, its effective polishing area is limited. In response to the above-mentioned polishing problems, the present invention proposes a scale-adjustable ultrasonic-assisted rotating line jet polishing device, which can rotate the ejected line jet to increase the polishing area. At the same time, the ultrasonic energy field is used to assist in further improving the polishing efficiency of high-hardness materials. The adjustable design of the jet nozzle opening significantly enhances the adaptability to working conditions, expands the scope of application in multiple fields, and greatly enhances the commercial value of the product. Summary of the Invention

[0057] like Figure 16 、 Figure 17 As shown, the integral fixing bracket 11 includes a polishing tool fixing bolt hole 1101 and an external fixing bolt hole 1102. The polishing tool fixing bolt hole 1101 is connected to the bolt hole on the flange of the ultrasonic generator 12 via bolts, thereby fixing the entire polishing tool. The external fixing bolt hole 1102 is used to connect to an external actuator.

[0058] like Figure 7 and Figure 17 As shown, the ultrasonic generator 12 includes an ultrasonic transducer 1201, a front end of a transformer 1202, and a terminal end of a transformer 1203; the ultrasonic transducer 1201 converts electrical energy into mechanical vibration, and enhances the vibration of the terminal end of the transformer 1203 through the amplitude amplification effect of the front end of the transformer 1202; the front end of the transformer 1202 and the terminal end of the transformer 1203 are detachably connected by threads, which facilitates the replacement of the terminal end of the transformer 1203 which is easily damaged by the cavitation effect; the terminal end of the transformer 1203 vibrates at high frequency in the conical shroud 0405, so that the ejected abrasive flow has a pulse effect.

[0059] In the present invention, the stepping motor 0101 drives the motor output gear 0102 to rotate, and the motor output gear 0102 engages to drive the upper transmission gear 0303 to rotate, thereby driving the hollow rotating flange 03 to rotate; the hollow rotating flange 03 is connected to the nozzle flange 04 via bolts, driving the nozzle flange 04 to rotate, causing the linear abrasive flow ejected from the nozzle mouth 0406 to form a cylindrical jet, thereby expanding the polishing coverage area; at the same time, the lower transmission gear 0302 of the hollow rotating flange 03 rotates with it and drives the intermediate transmission gear 0304 to rotate; the shaft groove 0305 on the shaft of the intermediate transmission gear 0304 rotates with the shaft, and through its spline cooperation with the spline sleeve 100201 of the sliding gear group 1002, drives the entire sliding gear group 1002 to rotate.

[0060] Furthermore, in the present invention, when the upper attraction electromagnet 100401 is energized via the conductive slip ring 0903, it attracts the cylindrical ferromagnetic material 100204, drives the shift fork 100205 to slide the sliding gear set 1002 upward, causing the length adjustment transmission gear 100202 to engage and drive the length adjustment upper end gear 0604 to rotate; the length adjustment upper end gear 0604 drives the length adjustment fixed bracket 0602 to rotate, and then pulls the length adjustment plate 0803 to slide through the contraction of the length adjustment connecting rod 0804 to adjust the length of the jet beam. Conversely, when the downward-attracting electromagnet 100403 is energized via the conductive slip ring 0903, it attracts the cylindrical ferromagnetic material 100204, driving the shift fork 100205 to slide the sliding gear set 1002 downward, causing the width-adjusting transmission gear 100203 to engage and drive the upper width-adjusting gear 0704 to rotate. The upper width-adjusting gear 0704 then rotates the width-adjusting fixed bracket 0703, which in turn, through the contraction of the width-adjusting connecting rod 0802, pulls the width-adjusting plate 0801 to slide, thereby adjusting the width of the jet beam. By controlling the rotation direction of the stepper motor 0101, the jet beam can be lengthened / shortened or widened / narrowed, respectively.

[0061] As the most preferred embodiment of the present invention, the end areas of the nozzle opening 0406, the width adjustment plate 0801 and the length adjustment plate 0803 where the abrasive flow is ejected all need to be subjected to wear-resistant treatment.

[0062] When the present invention is applied, the polishing process is completed as follows: the polishing device is installed on a robotic arm, or on the drive mechanism of the vertical axis (Z axis) of the machine tool. First, the workpiece to be processed is fixed on the processing table of the CNC machine tool; the stepper motor 0101 is started, and the opening size of the nozzle opening 0406 is adjusted according to the processing requirements. The adjustment is completed as shown in FIG. Figure 18 As shown. Secondly, the abrasive flow is injected into the abrasive flow inlet 0202 through the delivery pipe, and the ultrasonic generator 12 is started, so that the abrasive flow is ejected from the nozzle 0406 as a pulsed abrasive jet. When rotating linear jet processing is required, the rotation rate of the polishing tool is adjusted by controlling the power source 01 to form a cylindrical pulse jet. The abrasive flow inside the polishing tool flows as shown. Figure 19 shown.

[0063] Compared with the traditional single jet beam polishing without pulse effect, the abrasive jet of the present invention has significant advantages: first, the rotatable linear jet greatly expands the polishing area; second, the end of the variable amplitude rod 1203 vibrates at high frequency in the conical guide cover 0405, so that the ejected abrasive jet beam has a pulse effect, which significantly improves the impact strength of the abrasive particles, thereby greatly improving the polishing efficiency.

[0064] Furthermore, compared to linear jets with fixed nozzle openings, the present device achieves adjustable abrasive jet width and length, significantly enhancing adaptability to diverse workpieces. The fluid's inherently conformable nature makes it particularly suitable for contour polishing of complex shapes, high-curvature surfaces, and free-form surfaces. Using a flexible fluid as the abrasive driving medium effectively avoids workpiece damage caused by hard pressing. The adjustable nozzle opening also makes it widely applicable to precision components, craft exhibits, and engineering applications requiring complex surfaces.

[0065] This invention not only significantly enhances product applicability but also significantly improves polishing efficiency through the use of a rotatable pulsed jet beam. Automatically controlled by the gear switching unit 10, the length and width of the nozzle jet beam can be adjusted, allowing the device to better adapt to complex machining surfaces. Consequently, the device of the present invention achieves highly efficient and high-quality polishing operations.

[0066] The above embodiments are only preferred embodiments of the present invention and are not limitations on the technical solutions of the present invention. Any technical solution that can be implemented on the basis of the above embodiments without creative work should be deemed to fall within the scope of protection of the patent of the present invention.
