[0038] This embodiment provides a powder filling tool for hot isostatic pressing package, such as Figure 1 As shown, it includes a motor 1, a vibration component 2, a rotation component 3, an inclination adjustment component 4 and a limiting component 5; the vibration component 2 is fixed to one end of the output shaft of the motor 1, the rotation component 3 is installed in the middle of the output shaft of the motor 1, the lower part of the rotation component 3 is fixedly connected to the inclination adjustment component 4, and the limiting component 5 is installed at the bottom end of the vibration component 2.

[0039] The motor 1 rotates, driving the vibration component 2 to vibrate. At the same time, the motor 1 drives the rotating component 3 to rotate. Due to the existence of the inclination adjustment component 4, the rotating component 3 has a certain inclination angle while the vibration component 2 vibrates, and the inclination angle changes automatically, so that when facing the situation where the structure in the package is more complicated, the compaction effect can still be guaranteed.

[0040] like Figure 3 and Figure 5 As shown, the rotating member 3 includes a driving gear 31 , a transfer gear 32 , an inner gear ring 33 , a second connecting rod 34 and a slewing bearing 35 .

[0041] The driving gear 31 is fixed at the middle of the output shaft of the motor 1 , the driving gear 31 meshes with the intermediate gear 32 , the intermediate gear 32 meshes with the inner gear ring 33 , and three evenly distributed second connecting rods 34 are fixed to the lower end of the inner gear ring 33 , and the end of the second connecting rod 34 is fixedly connected to the slewing bearing 35 .

[0042] The output shaft of the motor 1 drives the driving gear 31 to rotate, the driving gear 31 drives the intermediate gear 32 to rotate, the intermediate gear 32 drives the inner ring gear 33 to rotate, the number of revolutions per minute of the inner ring gear 33 is less than the number of revolutions per minute of the driving gear 31, the slewing bearing 35 and the second connecting rod 34 support the position of the inner ring gear 33, and the inner ring gear 33 drives the inclination adjustment member 4 to rotate.

[0043] Preferably, Figure 3 As shown, the inclination adjustment component 4 includes a fixed support rod 41, a walking wheel 42 and a telescopic support assembly 43; one of the second connecting rods 34 is fixedly connected to the telescopic support assembly 43, and the other two second connecting rods 34 are fixedly connected to the fixed support rod 41, and the bottom ends of the telescopic support assembly 43 and the fixed support rod 41 are both fixed to the walking wheel 42.

[0044] Preferably, Figure 4 As shown, the telescopic support assembly 43 includes an intermediate rod 431 , a sliding sleeve rod 432 , a threaded rod 433 , a square block 434 , a third rod body 435 and a hexagonal socket 436 .

[0045] The upper and lower parts of the intermediate rod 431 are both sleeved with the sliding sleeve rod 432, and the middle part of the intermediate rod 431 is provided with a threaded groove, in which the threaded rod 433 is installed, and the end of the threaded rod 433 is connected to the square block 434 through a bearing, and both sides of the sliding sleeve rod 432 are hinged to one end of the third rod body 435, and the other end of the third rod body 435 is hinged to the square block 434, and the end of the threaded rod 433 is provided with the hexagonal groove 436.

[0046] By rotating the threaded rod 433, the threaded rod 433, under the action of the threaded groove, makes the sliding sleeve rod 432 approach or move away from the middle rod 431, thereby realizing the extension and retraction of the telescopic support assembly 43, that is, the length of the middle rod 431 and the sliding sleeve rod 432 of the telescopic support assembly 43 can be adjusted to be greater than or equal to the length of the fixed support rod 41. When the length of the middle rod 431 and the sliding sleeve rod 432 is greater than the length of the fixed support rod 41, the plane where the slewing bearing 35 supported by the fixed support rod 41 and the telescopic support assembly 43 is located forms an angle with the horizontal plane, and the center line of the output shaft of the motor 1 fixedly connected to the slewing bearing 35 is perpendicular to the plane where the slewing bearing 35 is located, that is, the center line of the output shaft of the motor 1 forms an angle with the vertical line of the horizontal plane.

[0047] Since the inner gear ring 33 drives the inclination adjustment component 4 to rotate, the center line of the output shaft of the motor 1 will rotate around a vertical line perpendicular to the horizontal plane, that is, the center line of the output shaft of the motor 1 and the vertical line perpendicular to the horizontal plane remain at a certain angle, but the direction keeps changing, so that the vibration component 2 has a certain inclination angle while vibrating, and the inclination angle keeps changing.

[0048] Preferably, Figure 5 As shown, the limiting member 5 includes a telescopic rod 51, a universal ball 52 and a ball mounting plate 53; at least three circumferentially evenly distributed universal balls 52 are installed at the lower part of the ball mounting plate 53, and the universal ball 52 is fixedly connected to the telescopic rod 51, and the lower end of the telescopic rod 51 is fixedly connected to the ground.

[0049] Three circumferentially evenly distributed universal balls 52 and telescopic rods 51 enable the motor and the vibration component 2 to tilt but not to rotate along the center line direction of the output shaft of the motor 1 .

[0050] Preferably, Figure 2 As shown, the vibration component 2 includes a rotating wheel 21, a limiting sliding rod 22, a lower wavy hollow disc 23, a hollow cylinder 25, a first hollow circular plate 26 and a sheath placement fixing disc 27.

[0051] The output shaft of the motor 1 is fixedly connected to the turntable, the limiting slide bar 22 is fixed to the middle part of the upper end surface of the turntable, and the upper end surface of the turntable is fixed with the rotating wheel 21 evenly distributed in the circumferential direction, the outer side of the limiting slide bar 22 is slidably connected to the hollow cylinder 25, the lower end of the hollow cylinder 25 is fixed with a lower wavy hollow disk 23, the lower wavy hollow disk 23 is in contact with the rotating wheel 21, the upper end of the hollow cylinder 25 is fixed with the sleeve placement fixed disk 27, and the upper end of the lower wavy hollow disk 23 is installed with a reset component.

[0052] The output shaft of the motor 1 drives the turntable to rotate, and the turntable drives the rotating wheel 21 to rotate. When the rotating wheel 21 rotates, it drives the lower wavy hollow disk 23 to rise and fall. The lower wavy hollow disk 23 drives the package placement fixed disk 27 to rise and fall through the hollow cylinder 25, forming vibration.

[0053] The lifting direction of the sleeve placement fixing plate 27 is the same as the center line direction of the output shaft of the motor 1, and changes with the direction of the center line of the output shaft of the motor 1, that is, the vibration component 2 has a certain tilt angle while vibrating, and the tilt angle changes automatically.

[0054] Preferably, the reset assembly includes a reset spring 24 , a first hollow circular plate 26 , a first connecting rod 28 and a bottom plate 29 .

[0055] The upper and lower ends of the return spring 24 are respectively fixed to the first hollow circular plate 26 and the lower wavy hollow disk 23. The lower part of the first hollow circular plate 26 is fixedly connected to one end of the first connecting rod 28. The other end of the first connecting rod 28 is fixedly connected to the bottom plate 29. The bottom plate 29 is fixedly connected to the lower end of the motor 1.

[0056] The lower end surface of the base plate 29 is fixedly connected to the swivel bearing 35 .

[0057] The setting of the return spring 24 can assist the lower wave-shaped hollow disc 23 to return downward quickly.

[0058] Preferably, the number of the rotating wheels 21 is three, and the lower wave surface of the lower wave-shaped hollow disk 23 has the same number of highest points and lowest points as the number of the rotating wheels 21 .

[0059] When the output shaft of the motor 1 rotates one circle, the sleeve placement fixing plate 27 vibrates three times.

[0060] If the inner gear ring 33 rotates 1 circle, the output shaft of the motor 1 rotates 10 circles. At this time, the sleeve placement fixing plate 27 vibrates 30 times, and the directions of these 30 vibrations are all different, that is, the raw material in the sleeve fixed on the sleeve placement fixing plate 27 vibrates once in 30 different directions.

[0061] Preferably, the inclination angle adjustment member 4 can adjust the inclination angle α of the vibration member 2 relative to the vertical upward direction, 3°≥α≥0°.

[0062] Preferably, the rotation centerline of the slewing bearing 35 coincides with the rotation centerline of the output shaft of the motor 1 .

[0063] Preferably, the transfer gear 32 is fixed relative to the motor 1 through a bearing seat and a third connecting rod.

[0064] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any changes or substitutions that can be easily thought of by any technician familiar with the technical field within the technical scope disclosed in the present invention should be included in the protection scope of the present invention.
