Embodiment 1

[0045] Such as Figure 1-Figure 8 As shown, a honeycomb material ultrasonic cutting test platform includes: five-axis motion platform (including workbench 1, Y-axis slide table 2, X-axis slide table 3, Z-axis slide table 4, A / C swing head 5), Ultrasonic cutting special mechanical spindle device 6, cutting temperature measuring device 7, ultrasonic vibration performance measuring device 8, honeycomb material clamping device 9 and cutting force measuring device 10, said ultrasonic cutting special spindle device 6 is fixed on the A / C pendulum On the head 5, the cutting force measuring device 10 is fixed on the workbench 1, the honeycomb material clamping device 9 is fixed on the cutting force measuring device 10, the cutting temperature measuring device 7 and the ultrasonic The vibration performance measuring device 8 is fixed on the said ultrasonic cutting special spindle device 6 .

[0046] The special mechanical spindle device 6 for ultrasonic cutting includes: an outer sleev...

Embodiment 2

[0061] Such as Figure 9 and 10 As shown, a test platform for ultrasonic cutting of honeycomb materials, the difference between it and Embodiment 1 is that the output end of the ultrasonic vibration system 18 is equipped with a straight-edged sharp knife.

[0062] When working, the servo motor 19 is controlled by the servo motor control system, and through the pulley drive, it provides the ultrasonic vibration system 18 with rotational motion, which can realize the fine adjustment of the direction of the straight edge sharp knife. After determining the direction of the cutting edge, the servo motor control system controls the braking of the servo motor 19 to keep the cutting edge moving in the direction required by the test. The mechanical spindle device 6 dedicated for ultrasonic cutting can be rotated by the A / C swing head 5 to obtain different tool inclination angles. Experimental research on cutting honeycomb materials by using the straight-edged pointed knife under diff...

Embodiment 3

[0064] Such as Figure 11-Figure 13 As shown, a honeycomb material ultrasonic cutting test platform, the difference between it and Example 1 is that the honeycomb material clamping device 9 is a honeycomb material vacuum adsorption clamping device; the honeycomb material vacuum adsorption clamping device includes a vacuum Adsorption platform 49 and vacuum generator.

[0065] When working, the vacuum adsorption platform 49 is installed on the upper end of the cutting force measuring device 10, the lower end of the honeycomb material is pasted with a film or metal plate, the honeycomb material is placed on the vacuum adsorption platform 49, and the vacuum generating device is started. Realize the vacuum adsorption clamping of the honeycomb material; after the test is over, turn off the vacuum generating device, the negative pressure of the vacuum adsorption platform 49 disappears, and the honeycomb material is removed.

The platform is characterized in that the special mechanical main shaft device for ultrasonic cutting is fixed to an A / C front sway of the five-axis moving platform; the cutting force measuring device is fixed to a worktable ofthe five-axis moving platform; the honeycomb material clamping device is fixed to the cutting force measuring device; and the cutting temperature measuring device and the ultrasonic vibrating performance measuring device are fixed to the special mechanical main shaft device for ultrasonic cutting. The ultrasonic cutting testing platform disclosed by the invention is suitable for different types of ultrasonic cutting tools, is suitable for honeycomb materials of different specifications and different dimensions, and is various in test types.

Description

technical field [0001] The invention relates to a test platform, in particular to a honeycomb material ultrasonic cutting test platform. Background technique [0002] At present, honeycomb materials are used as excellent high-strength and Ultra-light structure, widely used in aviation, aerospace, ships and high-speed trains and other fields. At the same time, due to its porous, thin wall and weak rigidity, it brings great difficulties to its high-quality and high-efficiency machining. The ultrasonic cutting method of honeycomb material based on the traditional high-speed milling method of honeycomb material is one of the technical means to solve the problem of difficult machining. Processing under appropriate ultrasonic cutting process parameters will result in a high-quality processed surface of honeycomb materials. Due to the thin-walled discontinuous structure and anisotropy of the honeycomb material, the cutting force during the ultrasonic cutting process is not const...
