Description

Technical Field

[0001] This invention relates to the field of machining technology, and in particular to an apparatus and method for simultaneous ultrasonic planing and deburring. Background Technology

[0002] Ultrasonic planing is an advanced machining method. During the planing process, the cutting edge of the tool not only performs conventional planing motions but also experiences a high-frequency reciprocating micro-vibration superimposed along the cutting direction. This high-frequency vibration significantly enhances the cutting effect and penetration capability, resulting in a substantial improvement in machining efficiency and quality.

[0003] However, ultrasonic planing also has certain problems during the processing. Due to the characteristics of planing, burrs are often generated on the workpiece surface. For workpieces with high surface quality requirements, these burrs must be removed. However, traditional deburring usually needs to be performed after planing, which not only reduces processing efficiency but also makes it difficult to guarantee the deburring effect.

[0004] This problem is particularly prominent when processing optically functional textured mold cores. Because the mold core surface contains tens of thousands of microstructures per square centimeter, deburring after ultra-precision planing becomes extremely difficult. For example, when using conventional ultrasonic cavitation deburring, the disordered distribution of cavitation bubbles leads to a lack of concentration in the impact force of the collapsing microjets, causing the fine burrs to be irregularly torn apart. This not only fails to precisely remove burrs but also easily damages the processed functional surface during the removal process, resulting in a residual surface quality that fails to meet the surface precision requirements of the mold core.

[0005] In summary, if a simple structure can be used to deburr the workpiece surface while performing ultrasonic planing, it will significantly improve processing efficiency and quality. Summary of the Invention

[0006] The purpose of this invention is to provide an apparatus and method for simultaneous ultrasonic planing and deburring. The technical problem to be solved is to perform deburring on the surface of a workpiece while ultrasonic planing using a simple structure.

[0007] To achieve the above objectives, the solution of the present invention is: an ultrasonic planing device for simultaneous deburring, used for planing a workpiece immersed in cutting fluid, comprising a planing tool and an ultrasonic generator, the planing tool being mounted on the ultrasonic generator, the ultrasonic generator being used to drive the planing tool to generate ultrasonic vibration along the machining direction, enabling the planing tool to perform ultrasonic planing on the workpiece surface through its cutting edge, a vibration plate being formed on the planing tool, the vibration plate being located above the rear part of the cutting edge along the machining direction, having a vibration surface facing forward and downward, facing the rear part of the cutting edge, the vibration surface being immersed in the cutting fluid during ultrasonic planing.

[0008] Furthermore, two vibration plates are provided, located on the left and right sides above the rear of the cutting edge, with the vibration surfaces of the two vibration plates facing the left and right sides of the rear of the cutting edge, respectively.

[0009] Furthermore, the planer includes a handle and a blade. The bottom end of the handle forms a triangular pyramid shape with the tip pointing downwards. One side of the triangular pyramid faces forward and serves as the mounting surface. The blade is mounted and fixed on the mounting surface. The bottom edge protrudes downwards from the lower edge of the handle and gradually tapers inwards to form a cutting edge. The other two sides of the triangular pyramid are located on the rear side of the handle and are symmetrical, forming a rear cutting face. A vibration plate is formed on one of the rear cutting faces.

[0010] Furthermore, the blade is made of diamond.

[0011] Furthermore, the ultrasonic generating device includes an ultrasonic generator, an ultrasonic transducer, and an ultrasonic amplitude transformer. The ultrasonic generator is used to generate ultrasonic alternating current. The ultrasonic transducer is electrically connected to the ultrasonic generator and is used to receive the ultrasonic alternating current and convert it into ultrasonic mechanical vibration. The ultrasonic amplitude transformer is mounted on the ultrasonic transducer to generate ultrasonic vibration under the drive of the ultrasonic transducer. The planer is mounted on the ultrasonic amplitude transformer.

[0012] Furthermore, it also includes a planer, which includes a gantry and a planer blade displacement drive mechanism. The planer blade displacement drive mechanism is mounted on the gantry, and an ultrasonic transducer is mounted on the planer blade displacement drive mechanism. The planer blade displacement drive mechanism drives the ultrasonic transducer to move, and the planer blade is mounted on the ultrasonic transducer and moves with the ultrasonic transducer.

[0013] Furthermore, the workpiece is an optically functional textured mold core.

[0014] A method for simultaneous ultrasonic deburring, using an ultrasonic deburring apparatus as described above, includes the following steps:

[0015] S1. With the workpiece facing upwards, immerse the workpiece in the cutting fluid and fix it in place;

[0016] S2. Turn on the ultrasonic generator to drive the planer to generate ultrasonic vibration along the machining direction;

[0017] S3. The planer is driven to move along a predetermined path on the surface to be machined on the workpiece by a planer displacement drive mechanism. Ultrasonic planing is performed on the surface to be machined on the workpiece. During ultrasonic planing, the vibrating surface is placed in the cutting fluid. The vibrating surface vibrates ultrasonically with the planer, so that the cavitation effect inside the cutting fluid is generated by the vibrating surface to produce bubbles. The burrs generated after the workpiece is cut by the cutting edge are removed by the bursting of the bubbles at the rear of the cutting edge.

[0018] The beneficial effects of the present invention after adopting the above scheme are as follows: the workpiece is immersed in the cutting fluid, the planer is mounted on the ultrasonic generator, the ultrasonic generator drives the planer to generate ultrasonic vibration along the processing direction, so that the planer can perform ultrasonic planing on the surface of the workpiece through its cutting edge. A vibration plate is formed on the planer. Along the processing direction, the vibration plate is located above the rear part of the cutting edge and has a vibration surface facing forward and downward, facing the rear part of the cutting edge. During ultrasonic planing, the vibration surface is immersed in the cutting fluid. At the same time as the planer vibrates ultrasonically, it drives the vibration surface to vibrate in the cutting fluid, causing cavitation effect inside the cutting fluid and generating bubbles. Since the vibration surface faces forward and downward, facing the rear part of the cutting edge, the bubbles can act on the workpiece surface where the planer cutting edge has just cut. By the bursting of the bubbles, the burrs generated after the workpiece is cut by the cutting edge are removed. Thus, with a simple structure, deburring treatment of the workpiece surface is achieved at the same time as ultrasonic planing. Attached Figure Description

[0025] The present invention will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0027] This invention provides a device for simultaneous deburring via ultrasonic planing, such as... Figure 1-5 As shown, the workpiece is used for planing. Specifically, in this embodiment, the workpiece is a light-functional textured mold core. The workpiece is immersed in cutting fluid 2 and includes a planer 3 and an ultrasonic generator 4. The planer 3 is mounted on the ultrasonic generator 4. The ultrasonic generator 4 can be any existing device that can drive the planer 3 to generate ultrasonic vibration along the processing direction, so that the planer 3 can perform ultrasonic planing on the workpiece surface through its cutting edge 5. Ultrasonic planing is a common technique in the field. During the planing process, the cutting edge 5 of the planer 3 not only performs conventional planing motion, but also superimposes a high-frequency reciprocating micro-vibration along the cutting direction, which enhances the cutting effect and penetration ability, thereby greatly improving the processing efficiency and processing quality. In this invention, a vibrating plate 6 is formed on the planer 3. Along the machining direction, the vibrating plate 6 is located above the rear part of the cutting edge 5 and has a vibrating surface 7 facing downwards and towards the rear part of the cutting edge 5. During ultrasonic planing, the vibrating surface 7 is immersed in the cutting fluid 2, thereby causing the planer 3 to reciprocate along the machining direction. While planing the workpiece, it also drives the vibrating surface 7 to reciprocate at high frequency in the cutting fluid 2. The vibrating surface 7 will cause cavitation effect in the cutting fluid 2, generating tiny bubbles 16 in the direction directly opposite the vibrating surface 7. Since the vibrating surface 7 is located... The tiny bubbles 16 generated by the cavitation effect above the rear part of the cutting edge 5, facing forward and downward, will act on the workpiece surface located at the rear part of the cutting edge 5. These bubbles will grow rapidly and burst under the constantly changing pressure generated by the ultrasonic high-speed vibration, forming a local high-speed jet that acts on the root of the burr and breaks it off, avoiding damage to other areas during processing. This can effectively remove the burrs generated on the edges during planing. Thus, through a simple structure, deburring of the workpiece surface is achieved simultaneously with ultrasonic planing.

[0028] Preferably, two vibration plates 6 are provided, located on the left and right sides above the rear of the cutting edge 5. The vibration surfaces 7 of the two vibration plates 6 face the left and right sides of the rear of the cutting edge 5, respectively, so that the cavitation bubbles 16 can accurately land on the two edges and inner corners of the workpiece after planing, so as to more effectively remove burrs from the left and right sides of the rear of the cutting edge 5. Specifically, in this embodiment, the planer 3 includes a handle 8 and a blade 9. The bottom end of the handle 8 forms a triangular pyramid shape with the tip pointing downwards. One side of the triangular pyramid shape faces forward and is the mounting surface. The blade 9 is mounted and fixed on the mounting surface. The bottom edge protrudes downwards from the lower edge of the handle 8 and gradually tapers inwards to form the cutting edge 5. The other two sides of the triangular pyramid shape are located on the rear side of the handle 8, symmetrically arranged, and are respectively a rear cutting face 10. A vibration plate 6 is formed on each rear cutting face 10.

[0029] Preferably, in this embodiment, the blade 9 is made of diamond to ensure the hardness of the blade.

[0030] Specifically, in this embodiment, the ultrasonic generating device 4 includes an ultrasonic generator 11, an ultrasonic transducer 12, and an ultrasonic amplitude transformer 13. The ultrasonic generator 11 generates an ultrasonic alternating current. The ultrasonic transducer 12 is electrically connected to the ultrasonic generator 11 and receives the ultrasonic alternating current, converting it into ultrasonic mechanical vibration. The ultrasonic amplitude transformer 13 is mounted on the ultrasonic transducer 12 to generate ultrasonic vibration under the drive of the ultrasonic transducer 12. The planer 3 is mounted on the ultrasonic amplitude transformer 13 and then receives the ultrasonic alternating current through the ultrasonic generating device 4. The ultrasonic alternating current is transmitted to the ultrasonic transducer 12, which converts the ultrasonic alternating current into ultrasonic reciprocating vibration in the processing direction (this is a conventional technical means, and its specific structure and principle will not be described in detail). This drives the ultrasonic amplitude transformer 13 to generate ultrasonic reciprocating vibration. The ultrasonic amplitude transformer 13 plays the role of expanding the amplitude. The planer 3 is mounted and fixed on the ultrasonic amplitude transformer 13 and performs ultrasonic reciprocating vibration under the drive of the ultrasonic amplitude transformer 13.

[0031] Specifically, in this embodiment, the displacement of the planer 3 is achieved through the following mechanism: the ultrasonic planing device for synchronous deburring also includes a planer 14, which includes a gantry 15 and a planer displacement drive mechanism. The planer displacement drive mechanism 17 is mounted on the gantry 15, and the ultrasonic transducer 12 is mounted on the planer displacement drive mechanism. The planer displacement drive mechanism 17 drives the ultrasonic transducer 12 to move. The planer 3 is mounted on the ultrasonic transducer 12 and moves with the ultrasonic transducer 12. The specific structure is not limited, and those skilled in the art can set it as needed.

[0032] A method for simultaneous ultrasonic deburring, using an ultrasonic deburring apparatus as described above, includes the following steps:

[0033] S1. With the workpiece facing upwards, immerse the workpiece in the cutting fluid 2 and fix the workpiece in place;

[0034] S2. Turn on the ultrasonic generator 11 to drive the planer 3 to generate ultrasonic vibration along the processing direction;

[0035] S3. The planer 3 is driven to move by the planer displacement drive mechanism, so that the cutting edge 5 of the planer 3 moves along a predetermined path on the surface to be machined of the workpiece, and ultrasonic planing is performed on the surface to be machined of the workpiece. During the ultrasonic planing process, the vibration surface 7 is placed in the cutting fluid 2. The vibration surface 7 is ultrasonically vibrated with the planer 3, so that the cavitation effect inside the cutting fluid 2 is generated by the vibration surface 7 to produce bubbles 16. The burrs generated after the workpiece is cut by the cutting edge 5 are removed by the bursting of the bubbles 16 at the rear position of the cutting edge 5.

[0036] The above description is only a preferred embodiment of the present invention and is not intended to limit the design of this case. All equivalent changes made based on the key design features of this case shall fall within the protection scope of this case.
