Abstract
Description
Technical Field
[0001] The invention relates to the field of ultrasonic machining, and in particular to an ultrasonic vibration group-axis tool holder and a system thereof. Background Art
[0002] Mechanical parts often have structures that are repeatedly arranged in a certain pattern, such as slots and holes. If they are processed in the conventional form of a single spindle, a single tool holder, and a tool, a large number of repeated processing paths are required, and the processing efficiency is low. In the field of machining, there are also applications that use multi-spindle machine tools for processing, but considering the overall versatility and economy, most conventional machine tools only have one spindle system. On conventional machine tools, the processing efficiency of repeated structures can be greatly improved by converting a single-axis structure into a multi-axis structure through a tool holder, and at the same time, tool holders of different forms can be used to adapt to different processing scene requirements. This tool holder is generally called a multi-axis device, which is a new type of processing equipment. For repeated structures, such as holes, it can greatly improve the processing efficiency, but ordinary multi-axis devices have low speeds and large cutting forces, and it is difficult to process hard and brittle materials, composite materials, or difficult-to-process metal materials. The corresponding processing quality is poor and the efficiency is low.

The first gear 13 is fixed to the power input handle 12 and the first bearing 14 is pre-tightened through the first sleeve 15; and the outer ring of the first bearing 14 is fixedly connected to the power input base 11 to form a power input assembly 1 with high rigidity and high speed. In a specific example, the first bearing 14 can adopt a double-row angular contact bearing, which can withstand axial force and radial force at the same time, and is suitable for being arranged at the position of the first bearing 14 to withstand the overall weight of the ultrasonic vibration group shaft handle.
[0057] The ultrasonic group axis assembly 2 includes an ultrasonic group axis base 21 and a plurality of ultrasonic tool handle modules 22. The ultrasonic group axis base 21 is fixedly connected to the power input base 11.

In a specific example, the second bearing 225 adopts a deep groove ball bearing, which can bear radial force during rotation.
[0058] The front end of the rotating shaft 221 is provided with a cavity 2211, and the rear end of the ultrasonic transducer 222 is accommodated in the cavity 2211; wherein, the secondary side unit 223 is fixedly connected to the outer ring of the rotating shaft 221 corresponding to the cavity 2211.

[0060] Combination Figure 5, the first gear 13 is connected to the second gear 224 in each ultrasonic handle module 22 so as to drive each second gear 24 to rotate simultaneously through the rotation of the first gear 13. In this embodiment, the axis of each second gear 224 is respectively located on the same circle with the axis of the first gear 13 as the center, and each second gear 224 is respectively meshed with the first gear 13. Specifically, the first gear 13 is larger than the second gear 224. In this example, the ultrasonic group axis assembly 2 includes four ultrasonic handle modules 22. Correspondingly, the first gear 13 is simultaneously meshed with four second gears 224 to transmit power to the tool 5. The second gear 224 can be a small spur gear. It should be noted that the number, type and arrangement of the gears only need to be adjusted according to the specific requirements of processing the group holes. The second gear 224 directly meshing with the first gear 13 can also drive other gears to rotate to form a variety of other transmission arrangements.
[0061] High-speed grease is added to the first bearing 14 and the second bearing 225 during installation, and circulating lubrication is not required; high-speed grease is used for the meshing of the first gear 13 and the second gear 224, and installation and maintenance are simple.
[0062] The primary side component 3 is connected to the ultrasonic generator 6 through a cable to receive the ultrasonic signal. Figure 6 The primary edge assembly 3 includes a primary edge base 31 and a plurality of primary edge units 32. The primary edge base 31 is fixedly connected to the ultrasonic group axis base 21. Specifically, the primary edge base 31 is fixedly connected to the ultrasonic group axis base 21 by a plurality of second locking screws 33 equally arranged along the circumferential direction. Each second locking screw 33 passes through a hole provided on the primary edge base 31 and is fixedly connected to a threaded hole on the ultrasonic group axis base 21. The plurality of primary edge units 32 are respectively fixedly connected to the primary edge base 31, and each primary edge unit 32 is arranged in a one-to-one correspondence with the secondary edge unit 223 in each ultrasonic handle module 22 to transmit the ultrasonic signal received by each primary edge unit 32 to each secondary edge unit 223; in this embodiment, the primary edge unit 32 is correspondingly arranged at the front side of the secondary edge unit 223. In other embodiments, the primary edge unit 32 can also be correspondingly arranged at the outer ring or the rear side of the secondary edge unit 223.

[0064] The high-frequency ultrasonic transmission path is as follows: the ultrasonic generator 6 generates a high-frequency ultrasonic signal, which is transmitted to multiple primary magnetic cores 321 through the cable of the primary component 3. The secondary magnetic core 2231 receives the high-frequency ultrasonic signal of the primary magnetic core 321 under high-speed rotation. The multiple piezoelectric ceramic sheets 2223 installed on the amplitude transformer 2224 undergo high-frequency deformation under the excitation of the high-frequency ultrasound of the secondary magnetic core 2231, and finally transmitted to the tool 5 through the amplitude transformer 2224. The tool end of the tool 5 generates a high-frequency vibration with the maximum amplitude. In this way, the tool 5 (such as a drill bit) performs drilling processing on difficult-to-process composite materials under the dual effects of high-speed rotation and high-frequency vibration. The multiple ultrasonic tool holder modules 22 work together to improve the processing efficiency of the group holes, and the deformation of the workpiece is small, and the generation of burrs can be greatly reduced, thereby improving the processing quality.
[0065] The ultrasonic vibration group-axis tool holder provided in this embodiment can be used for processing group holes and group grooves in hard and brittle composite materials, and can also greatly improve the processing efficiency, quality, and processing stability of group holes and group grooves of ordinary materials.
