[0039] The following is combined with Figure 1-7 This application is described in further detail.

[0040] Example 1, reference Figure 1-3 A titanium-aluminum laminate hot melt drilling processing device shown includes: an ultrasonic tool holder system 1, a hot melt drill 2, a tool 3, a fixing part 4, a machine tool handle 8, a T-shaped tool 9 and a polishing mechanism;

[0041] The ultrasonic tool holder system 1 is used to drive the hot melt drill 2 to process the titanium-aluminum laminated material 5;

[0042] The machine tool handle 8 is used to drive the T-shaped tool 9 to process the titanium-aluminum laminated material 5;

[0043] The tooling 3 is used to fix the titanium-aluminum laminated material 5, and the fixing member 4 is used to support the tooling;

[0044] The polishing mechanism is used for polishing the surface of the hot melt drill 2 .

[0045] Based on the above structure, the titanium-aluminum laminate material 5 is first pre-processed by a carbide T-shaped tool, and a number of blind holes 53 are processed in the titanium alloy layer, and the diameter of the blind holes 53 is 1.5 mm, and a cavity 52 is pre-processed in the aluminum alloy layer. The cavity 52 consists of a first hole close to the titanium alloy layer and a second hole far away from the titanium alloy layer, and the diameter of the first hole is 2 mm, and the diameter of the second hole is 1.5 mm; then the ultrasonic tool holder system 1 drives the hot melt drill 2 to cut, and the hot melt drill 2 is driven to realize rotational motion by inputting ultrasonic power and frequency. The hot melt drill 2 penetrates from the blind hole 53 into the cavity 52, and the hot melt drill 2 melts the titanium alloy layer on the ring side, and the titanium material is completely filled into the aluminum alloy cavity 52, realizing the titanium-aluminum laminate hole processing and material filling. During the drilling process, the hot melt drill 2 is polished at a certain frequency. For example, when drilling 20 holes, the drilling is paused. The hot drill surface is polished by the polishing mechanism to remove titanium alloy sticky chips on the hot drill surface, improve the wear of the hot melt drill 2, and achieve the improvement of tool life.

[0046] like Figure 2 As shown, the hot melt drill 2 includes a shank 21, a first transition section 22, a second transition section 23, a cylindrical section 24 and a drill tip 25 which are sequentially connected. The first transition section 22 and the second transition section 23 are both in the shape of a cone arc. The ends of the first transition section 22 and the second transition section 23 with smaller diameters face the end close to the drill tip 25. The hot melt drill 2 in the present application is designed with a two-section cone arc design. The first transition section 22 is connected to the shank 21 with a smaller arc to reduce the transition stress concentration of the shank 21. The second transition section 23 is a larger arc. During the drilling process, the chips move upward along the arc, which can effectively improve the chip flow during the hot drilling process. A contour structure is set between the drill tip 25 and the wheel cylindrical section 24. The drill tip 25 and the contour structure are the main locations where the titanium alloy undergoes plastic deformation and drilling and forming. The contour structure is fitted by a spline curve.

[0047] like Figure 1 and Figure 3 As shown, in order to accurately fix the titanium-aluminum laminated material 5, a groove 31 adapted to the titanium-aluminum laminated material 5 is opened on the top surface of the tool 3, and a plurality of fixing holes 32 for fixing the titanium-aluminum laminated material 5 are set at the bottom of the groove 31 of the tool 3. During processing, the titanium-aluminum laminated material 5 is placed in the groove 31 so that the titanium-aluminum laminated material 5 will not be deformed, and the titanium-aluminum laminated material 5 is fixed to the tool 3 by passing bolts through the through holes 51 of the titanium-aluminum laminated material 5.

[0048] like Figure 3 As shown, the tooling 3 is provided with a strip-shaped through hole 33 at the bottom of the groove 31, which is not only convenient for discharging waste chips generated during processing, but also convenient for processing the bottom of the titanium-aluminum laminated material 5 from the through hole 33, thereby eliminating the need to re-fix the titanium-aluminum laminated material 5.

[0049] like Figure 3 As shown, in order to facilitate the fixation of the tooling 3, the tooling 3 is provided with a plurality of first mounting holes 34 on the ring side of the groove 31, and the plurality of first mounting holes 34 are symmetrically arranged with the groove 31 as the symmetry axis, and the top of the fixing member 4 is provided with a plurality of second mounting holes 41, and the plurality of second mounting holes 41 correspond one to one with the plurality of first mounting holes 34. In this way, the tooling 3 is fixed to the fixing member 4 through the plurality of first mounting holes 34 and the plurality of second mounting holes 41, and the top surface of the titanium-aluminum laminated material 5 is processed first, and then the tooling and the titanium-aluminum laminated material 5 are removed as a whole, turned horizontally, and fixed to the fixing member 1 again, and the bottom of the titanium-aluminum laminated material 5 is processed through the through hole 33.

[0050] Further optimization is that Figure 4 As shown, in order to facilitate fixing the fixing part on the machine tool, a plurality of third mounting holes 42 are provided at the bottom of the fixing part 4; and a cavity 43 is provided between the second mounting hole 41 and the third mounting hole 42 of the fixing part 4, the cavity 43 is convenient for heat dissipation and reducing the weight of the tooling, and is convenient for fixing and installation, and the connecting groove 44 is used to position and fix the tooling 3.

[0051] like Figure 1 As shown, the polishing mechanism includes a motor 6 and a rough wheel 7. The rough wheel 7 is arranged at the output end of the motor 6. The driving motor 6 drives the rough wheel 7 to rotate, and the hot melt drill 2 moves to the position of the rough wheel 7 to polish the surface of the hot melt drill 2.

[0052] The present application also includes a second embodiment, a processing method of the titanium-aluminum laminate hot melt drilling processing device based on the first embodiment, the method specifically comprising: opening a plurality of through holes 51 adapted to the fixing holes 32 on the titanium-aluminum laminate material 5, and installing the titanium-aluminum laminate material 5 in the groove 31 through the plurality of through holes 51 and the plurality of fixing holes 32;

[0053] The fixing member 4 is fixed on the machine tool workbench through a plurality of third mounting holes 42;

[0054] Fix the tool 3 on the fixing member 4 through a plurality of first mounting holes 34 and a plurality of second mounting holes 41;

[0055] First, the T-shaped tool 9 is installed on the machine tool handle 8, and the machine tool handle 8 drives the T-shaped tool 9 to open a plurality of cavities 52 on the aluminum alloy layer of the titanium-aluminum laminated material 5;

[0056] The tooling 3 and the titanium-aluminum laminated material 5 are turned horizontally as a whole, and then fixed on the fixing member 4. The machine tool handle 8 drives the T-shaped tool 9 to open a plurality of blind holes 53 that match the mold cavity 52 one by one on the titanium alloy layer of the titanium-aluminum laminated material 5;

[0057] The hot melt drill 2 is mounted on the ultrasonic tool handle system 1, and the ultrasonic tool handle system 1 drives the hot melt drill 2 to process the titanium-aluminum laminated material 5 from each blind hole 53. During each processing, the hot melt drill 2 passes through the titanium alloy layer of the titanium-aluminum laminated material 5 until it reaches the cavity 52, and the titanium alloy layer of the titanium-aluminum laminated material 5 close to the hot melt drill 2 is melted to form a bushing at the cavity 52, thereby completing the fusion of the titanium-aluminum two materials;

[0058] When the hot melt drill 2 is processing, the polishing mechanism polishes the surface of the hot melt drill 2 according to the frequency. For example, when drilling 20 holes, the drilling is suspended. The polishing mechanism polishes the hot drill surface to remove titanium alloy chips on the hot drill surface, improve the wear of the hot melt drill 2, and achieve a longer tool life.

[0059] In summary, during the cutting process of the ultrasonic tool holder system 1 driving the melt drill 2, the ultrasonic power and frequency are input to drive the melt drill 2 to realize rotational motion. The melt drill 2 penetrates from the blind hole 53 into the cavity 52. ​​The melt drill 2 plastically deforms the titanium alloy layer on the ring side, and the titanium material is perfectly filled into the aluminum alloy cavity 52, thereby realizing titanium-aluminum laminated hole processing and material filling. During the drilling process, the melt drill 2 is polished at a certain frequency. For example, when drilling 20 holes, the drilling is paused. The polishing mechanism polishes the surface of the hot drill to remove titanium alloy chips on the surface of the hot drill, improve the wear of the melt drill 2, and achieve a longer tool life (such as Figure 7 As shown, there is a comparison diagram of the hot melt drill state after processing titanium-aluminum laminated materials in the prior art (before optimization) and the present application (after optimization).

[0060] The above are only preferred embodiments of the present application, and the present invention is not limited to the above embodiments. It is understood that other improvements and changes directly derived or associated by those skilled in the art without departing from the spirit and concept of the present invention should be considered to be included in the protection scope of the present invention.
