Description
Technical Field
The present invention relates to a processing apparatus, and more particularly, to an ultrasonic-assisted processing apparatus.
Background
Ultrasonic-assisted machining apparatuses assist in removing machining chips during machining of fine holes by using ultrasonic vibration, such as ultrasonic vibration, which effectively removes material from the fine holes during machining, for example, during machining of fine holes using a tool or an electrode. When the hole size is small and the hole diameter ratio is large, machining chips are not easy to remove due to the small gaps among the hole, the cutter and the electrode, and the cutter is damaged or fails to machine due to the fact that the cutter is reversely stressed after the cutter is stressed. In the micro-discharge process, for example, machining chips are not easy to remove, which results in poor machining efficiency or failure in machining holes with large aperture ratio, so the ultrasonic-assisted machining is used to solve the above-mentioned process problems.
The existing ultrasonic auxiliary processing device utilizes a resonance rod to transmit ultrasonic waves to a processing hole. The tail end of the resonance rod is provided with a through hole for a processing tool to pass through so as to drill a hole on the surface of an object to be processed. Because the through hole on the resonance rod is a closed structure at present, the processing tool has only one degree of freedom to separate from the through hole, which is not beneficial to the industrial mass production and the automatic production.
In view of the above problems, there is a need for more flexible application of ultrasound to assist hole processing in automated manufacturing.

Detailed Description
In order to solve the above problems, the present invention provides an ultrasonic-assisted machining apparatus, wherein the resonant rod has a design that is not constrained with respect to the machining tool/electrode, so as to effectively achieve the functions of ultrasonic vibration and tool/electrode exchange for automatic production, and meet the industrial application requirements.
Fig. 1 is a schematic side view of an ultrasonic auxiliary processing apparatus according to an embodiment of the invention. The ultrasonic auxiliary processing apparatus 100a includes a processing tool 102, a first resonance rod 106a, a second resonance rod 106b, and a liquid supply unit 104. In the present embodiment, the machining tool 102 may be an electric discharge machining discharge electrode, a drill, a milling cutter, or other machining tools capable of forming a hole 101a in the surface of the object 101 to be machined. The liquid supply unit 104 is used for supplying the processing liquid to a processing position where the processing tool 102 contacts with the object 101 to be processed. In this embodiment, the liquid supply unit 104 is connected to the processing liquid nozzle 104a, so that the processing liquid is sent out from the processing liquid nozzle 104a to the processing position. When the machining tool 102 performs a drilling process, the machining fluid nozzle 104a sprays the machining fluid to a position being machined, and the ends of the first resonant rod 106a and the second resonant rod 106b surround the machining tool 102. The ultrasonic vibrator 110 transmits the ultrasonic vibration to the processing position through at least one of the first resonant rod 106a and the second resonant rod 106b, in other words, the ultrasonic vibrator 110 may be connected to the first resonant rod 106a or the second resonant rod 106b, or both ends of the ultrasonic vibrator 110 may be disposed. The gap between the first resonant rod 106a and the second resonant rod 106b and the upper surface of the object 101 to be processed is used for retaining the processing fluid 103, so that the ultrasonic vibration can be effectively transmitted into the hole 101a through the resonant rods and the processing fluid to accelerate the discharge of the processing chips.
In the present embodiment, the first resonant beam 106a and the second resonant beam 106b each have a pivot 108a and a pivot 108b, so that they can be rotated away from the processing tool 102 (e.g., in the direction of the arrow in the figure) during non-processing. When the machining tool 102 needs to be replaced due to consumption, wear or other factors, the first resonant rod 106a and/or the second resonant rod 106b can be removed to facilitate the replacement of the machining tool 102, and the rotating direction can be adjusted as required. The first resonance rod 106a and/or the second resonance rod 106b can be integrated with the machine tool in cooperation with a cylinder, a link mechanism, etc. to achieve the function of automatic exchange of the tool and the electrode, so as to meet the industrial application requirement of the automatic production.
In other embodiments, the embodiment of fig. 1 may also be configured such that the entire ultrasonic auxiliary processing apparatus 100a is immersed in the processing fluid to perform the processing, for example, a container is used to contain the processing fluid, and the processing tool 102, the first resonant rod 106a, the second resonant rod 106b and the object 101 to be processed are immersed in the processing fluid to perform the processing.
Fig. 2 is a schematic side view of an ultrasonic-assisted processing apparatus according to another embodiment of the invention. The ultrasonic auxiliary processing device 100b is substantially the same as the ultrasonic auxiliary processing device 100a in design, but the liquid supply unit 104 is communicated with the processing liquid flow passage 112 in the resonant rod, so that the supplied processing liquid flows to the position being processed through the processing liquid flow passage 112 in the resonant rod and the liquid outlet hole 112a at the free end of the resonant rod. The processing fluid channel 112 may be designed in the first resonant rod 106a or the second resonant rod 106b, or both. Although the liquid outlet is formed at the free end of the resonant rod, the liquid outlet 112a shown in fig. 2 is formed at the lower surface (i.e. the surface opposite to the object to be processed) of the free end of the resonant rod 106a, the present invention is not limited thereto, for example, the liquid outlet may be formed at the free end of the resonant rod opposite to the surface (not shown) of the processing tool 102. In addition, the liquid outlet 112a shown in fig. 2 is a single opening, and the liquid outlet can be designed as a plurality of smaller openings according to actual requirements. The first resonant bar 106a and the second resonant bar 106b of the present embodiment may also have a pivot 108a and a pivot 108b, respectively, as in the embodiment of fig. 1, so that they can be rotated away from the processing tool 102 during non-processing.
Fig. 3 is a schematic top view illustrating a resonant rod and a processing tool of an ultrasonic auxiliary processing apparatus according to an embodiment of the invention. The first resonant rod 106a and the second resonant rod 106b of the ultrasonic auxiliary processing device are used to transmit the ultrasonic vibration to the processing position (i.e. the position to be processed by the processing tool 102 in the figure). Therefore, when the machining tool 102 is in operation, the ends of the first resonant rod 106a and the second resonant rod 106b surround the machining tool 102. In the present embodiment, the first resonant bar 106a has a first non-closing notch 114a, and the second resonant bar 106b has a second non-closing notch 114 b. When the processing tool 102 is in operation, the ends of the first resonant bar 106a and the second resonant bar 106b may be close to but not joined (a gap is reserved), so that the first non-enclosed gap 114a and the second non-enclosed gap 114b are symmetrical to each other with respect to the processing tool 102.
Fig. 4 is a schematic top view of a resonant rod and a processing tool of an ultrasonic auxiliary processing apparatus according to another embodiment of the invention. This figure differs from the embodiment of fig. 3 in the direction in which the shape of the resonant rod corresponds to the end. The first resonant rod 106a 'and the second resonant rod 106 b' of the ultrasonic auxiliary processing device are used to transmit ultrasonic vibration to the processing position (i.e. the position to be processed by the processing tool 102 in the figure). Therefore, when the machining tool 102 is being constructed, the ends of the first resonance rod 106a 'and the second resonance rod 106 b' surround the machining tool 102. In this embodiment, the first resonant rod 106a 'has a first non-closing notch 114 a', and the second resonant rod 106b 'has a second non-closing notch 114 b'. When the processing tool 102 is in operation, the ends of the first resonant bar 106a 'and the second resonant bar 106 b' may be close to but not joined, such that the first non-enclosed gap 114a 'and the second non-enclosed gap 114 b' are symmetrical to each other with respect to the processing tool 102.
Fig. 5 is a schematic top view illustrating a resonant bar and a processing tool of an ultrasonic auxiliary processing apparatus according to still another embodiment of the present invention. The first resonant rod 106a and the second resonant rod 106b of the ultrasonic auxiliary processing device are used to transmit the ultrasonic vibration to the processing position (i.e. the processing position of the processing tool 102 in the figure). Therefore, when the machining tool 102 is in operation, the ends of the first resonant rod 106a and the second resonant rod 106b surround the machining tool 102. In the present embodiment, the first resonant rod 106a has a first non-closing notch 114a, and the end of the second resonant rod 106b has no notch. When the machining tool 102 is in operation, the ends of the first resonant bar 106a and the second resonant bar 106b may be close to but not joined (as depicted in this figure).
Fig. 6 is a schematic top view illustrating a resonant bar and a processing tool of an ultrasonic auxiliary processing apparatus according to another embodiment of the present invention. The first resonant rod 106c and the second resonant rod 106d of the ultrasonic auxiliary processing device are used to transmit the ultrasonic vibration to the processing position (i.e. the position to be processed by the processing tool 102 in the figure). Therefore, when the machining tool 102 is being worked, the ends of the first resonant rod 106c and the second resonant rod 106d are looped around the machining tool 102. In the present embodiment, the first resonant bar 106c has a first non-closing notch 114c, and the second resonant bar 106c has a second non-closing notch 114 d. When the processing tool 102 is in operation, the ends of the first resonant bar 106c and the second resonant bar 106d can be close to but not joined (as illustrated in this figure), so that the first non-enclosed gap 114c and the second non-enclosed gap 114d are symmetrical to each other with respect to the processing tool 102.
Either or both of the resonant rods of FIGS. 3-6 described above can be rotated or moved away from the processing tool 102 during non-processing. When the machining tool 102 needs to be replaced due to consumption, wear or other factors, one or both of the resonant rods can be removed to facilitate the replacement of the machining tool 102, and the rotating direction can be adjusted as required. The rotation or movement of the resonance rod can be integrated with the machine tool in a manner of matching with an air cylinder, a connecting rod mechanism and the like, so that the function of automatic exchange of the cutter and the electrode is achieved, and the industrial application requirement of automatic production is met. The shape of the non-closed gap can also be adjusted according to the shape of the processing tool, and can be semicircular, semi-elliptical, rectangular or other shapes.
Referring to fig. 7 and 8, fig. 7 is a schematic top view illustrating a single resonant rod and a processing tool when the ultrasonic auxiliary processing apparatus according to an embodiment of the present invention is processing; FIG. 8 is a side view of the single resonant rod and the processing tool of FIG. 7 during processing. In the present embodiment, a non-constrained structure is realized by a single resonant rod, as shown in the figure, the non-enclosed notch 114 at the end of the single resonant rod 106 still surrounds the periphery of the processing tool 102, so that the processing fluid 103 is retained between the resonant rod 106 and the surface of the object 101 to be processed, and the ultrasonic vibration can be effectively transmitted to the hole 101a through the resonant rod 106 and the processing fluid 103, so as to accelerate the discharge of the processing chips. This embodiment may also have the design related to the resonant rod of the previous embodiment that rotates or moves away from the processing tool and the liquid supply unit when not processing.
The ultrasonic-assisted processing designs of the processing tool, the resonance rod, the vibrator, the liquid supply unit and the like can be more easily applied or integrated in various automatic production lines and large-scale equipment, so that the application field of the ultrasonic-assisted processing designs can be more expanded.
In summary, the ultrasonic auxiliary processing device of the present invention has a resonance rod with a non-constrained structure, and is integrated with a machine tool in cooperation with a cylinder, a link mechanism, etc. to meet the requirement of more convenient replacement of processing tools such as a cutter, an electrode, etc. so as to meet the industrial application requirement of automated production.
While the present invention has been described with reference to the preferred embodiments, it will be understood by those skilled in the art that various changes in form and details may be made therein without departing from the spirit and scope of the invention as defined by the appended claims.
