Description

Technical Field

[0001] This utility model relates to the technical field of ultrasonic machining, and in particular to the technical field of circular cutting tools used in ultrasonic machining. Background Technology

[0002] Sound waves with frequencies higher than 20 kHz are called ultrasound. Ultrasonic machining is a special machining method that uses ultrasonic vibrations to add high-frequency vibrational energy to the machining process; its English abbreviation is USM.

[0003] During processing, the cutting tool vibrates at an ultrasonic frequency, continuously hammering the workpiece surface with a high-frequency vibration of over 20,000 times per second, causing the workpiece to gradually break down. A circulating coolant carries away the pulverized material particles, allowing the cutting tool to gradually penetrate the material and shape the workpiece. Existing ultrasonic cutting tools are mostly long blade-shaped or cylindrical, unsuitable for processing materials such as honeycomb materials. Furthermore, the large contact area between existing ultrasonic cutting tools and the workpiece results in significant friction, leading to easy tool wear and overheating. Summary of the Invention

[0004] The purpose of this invention is to solve the problems in the prior art and to propose a circular cutting tool for ultrasonic machining. The cutting tool is disc-shaped, has a small contact area during machining, low friction, is not easily worn, and reduces the lifting of the workpiece during machining.

In this embodiment, the tool body 1 can be directly connected to the ultrasonic spindle of the machine tool through the connecting part 12. Ultrasonic cutting is performed through the tool body 11. During operation, the ultrasonic spindle vibrates and rotates at high speed. The cutting edge 111 can be close to the workpiece to complete the cutting. It is suitable for cutting workpieces such as honeycomb panels. The tool body 11 is disc-shaped and can be used for cutting in any direction. The cutting edge plane 1111 of the cutting edge 111 can be used to fit the workpiece, reducing the lifting of the workpiece by the tool body 1 during processing. The upper cutting edge bevel 1112 can facilitate the peeling off of the cut waste. The concave arc surface 112 provided on the lower side of the tool body 11 can reduce the contact area between the tool and the workpiece, which can reduce the friction and heat generation of the tool.

[0030] See Figure 1 , Figure 2 The connecting part 12 is cylindrical, with a mounting hole 121 at its center and a mounting surface 122 on its side wall. In use, it can be directly mounted on the ultrasonic spindle through the mounting hole 121.

[0031] Preferably, the width of the cutting edge plane 1111 is 10mm, and the width of the cutting edge bevel 1112 is 10mm. Example 2

[0032] See Figures 4-8Based on Embodiment 1, to address the problem of the inability to adjust the tool length in existing technologies, the connecting part 12 includes a first connecting block 123 and a second connecting block 124. The first connecting block 123 is used to connect with the machine tool spindle, and the second connecting block 124 is fixedly connected to the tool body 11. The first connecting block 123 is provided with a connecting cavity 1231 adapted to the second connecting block 124. The connecting cavity 1231 is arranged axially along the first connecting block 123, and the second connecting block 124 is axially slidably disposed within the connecting cavity 1231. The second connecting block 124 and the tool body 11 are connected in a specific configuration. A plurality of shims 125 are provided between the tops of the connecting cavity 1231.

In this embodiment, the connecting part 12 is configured to be composed of a first connecting block 123 and a second connecting block 124. The second connecting block 124 is connected to the first connecting block 123 through cooperation with the connecting cavity 1231. By setting shims 125 of different thicknesses in the connecting cavity 1231, the extension length of the second connecting block 124 can be adjusted, thereby adjusting the overall height of the tool body 1. The height of the tool body 1 is adjustable, which can meet various usage requirements and has stronger adaptability.

[0033] Preferably, this embodiment has a variety of connecting bolts 13 of different lengths, which can correspond to shims 125 of different thicknesses, making the connection more stable.

[0035] See Figure 7The second connecting block 124 has several 7-shaped slots 1243 arranged in a circular array at one end away from the blade body 11. The shim block 125 has several 7-shaped locking blocks 1252 at one end near the second connecting block 124 for engaging with the 7-shaped slots 1243. To facilitate the removal of the shim block 125 from the connecting cavity 1231, the shim block 125 and the second connecting block 124 are connected together. The shim block 125 and the second connecting block 124 are engaged with each other through the 7-shaped slots 1243 and the 7-shaped locking blocks 1252. In use, the 7-shaped locking blocks 1252 are inserted into the 7-shaped slots 1243 from the opening and then rotated relative to each other so that the corner position of the 7-shaped locking blocks 1252 can be locked in the corner position of the 7-shaped slots 1243, and the two are locked relative to each other.

[0036] See Figure 6 The outer wall of the raised block 125 is also provided with a directional groove 1241.
