Description

Technical Field

[0001] The present invention relates to the technical field of atomization devices, and in particular to a micro-motion stage support device, an atomization device, and a 3D printing powder preparation device. Background Art

[0002] As 3D printing technology penetrates increasingly diverse fields such as aerospace, petrochemicals, automotive molds, and new energy, the demand for spherical metal powders as raw materials for 3D printing is skyrocketing. Because 3D printing manufacturing technology places stringent demands on powder morphology and particle size distribution, large-volume atomizers are required to provide ample atomization reaction space and cooling time for spherification, achieving optimal powder sphericity and minimizing the adhesion of powder satellites. Because the metal powder atomization process involves an extremely complex energy exchange process, the installation and adjustment of the atomizer are crucial.

[0003] In the related art, a base is usually set at the bottom of the atomizer tank, and a lifting plate, a lifting rod and a lifting block are set in the inner cavity of the base, the lifting rod and the lifting block are respectively connected to the top and bottom of the lifting plate, the lifting rod is connected to the bottom of the atomizer tank, and support frames are provided at both ends of the lifting block. The bottom of the support frame is connected to the bottom of the atomizer tank, and the bottom of the support frame is fixedly connected to the support plate. The pressure block is set on both sides of the inner cavity of the base, and lifting wheels are provided on both sides of the lifting block to cooperate with the movement of the pressure block; adjustment boxes are provided on both sides of the base, the adjustment box is connected to the motor, and the output end of the motor is connected to the threaded rod, and the threaded rod is passed through the inner cavity of the adjustment box and a threaded sleeve is provided at one end. The opposite top and bottom of the threaded sleeve are fixedly connected to the connecting rod, and the end of the connecting rod facing away from the threaded sleeve is connected to the pressure block and is located in the inner cavity.

[0004] When the height of the atomizer tank needs to be adjusted, the motor runs and drives the threaded rod to reverse. The threaded rod's rotation drives the two pressure blocks to move toward the center through the cooperation of the threaded sleeve and the connecting rod. The pressure blocks squeeze the lifting wheel, driving the lifting wheel upward. The lifting wheel drives the lifting block upward. The lifting block drives the lifting plate and the support frame upward. The support frame drives the support plate upward and away from the ground. The lifting plate drives the atomizer tank upward through the cooperation of the lifting rod. Adjusting the atomizer device using this method is complicated. Summary of the Invention

[0042] Reference Figures 1 to 3The present invention proposes a micro-stage support device 100 for adjusting the height of an atomizing device 1000. The atomizing device 1000 includes an atomizing tank 300, a sealing ring 400, and a support structure 200. A receiving space 201a is formed in the support structure 200. The atomizing tank 300 is located in the receiving space 201a. The sealing ring 400 is sleeved on the outer peripheral side of the atomizing tank 300. The micro-stage support device 100 is fixedly mounted on the support structure 200 and connected to the atomizing tank 300. The micro-stage support device 100 includes a support The support assembly 10 and the lifting sleeve 30, the support assembly 10 includes a support base 11 and a support stud 13, the support stud 13 is connected to the support base 11, the support base 11 is fixedly installed on the support structure 200, and the support stud 13 is provided with a scale 133 at one end close to the support base 11, and the scales of the scale 133 are evenly spaced along the axial direction of the support stud 13; the lifting sleeve 30 is sleeved on the support stud 13 and can move up and down relative to the support stud 13, and the end of the lifting sleeve 30 away from the support base 11 is fixedly abutted against the atomizer tank 300.

[0043] The micro-movement stage support device 100 of the present application is used to adjust the height of the atomizing device 1000. The atomizing device 1000 includes an atomizing tank 300 and a support structure 200. The support structure 200 forms a receiving space 201a. The atomizing tank 300 is located in the receiving space 201a. The micro-movement stage support device 100 is fixedly mounted on the support structure 200 and connected to the atomizing tank 300. Among them, the support assembly 10 in the micro-movement stage support device 100 includes a support base 11 and a support stud 13. The support stud 13 is connected to the support base 11. The connection method can be integrally formed or other fixed connection methods, which are not limited here. The fixed connection between the support stud 13 and the support base 11 can maintain the structural stability of the support assembly 10 and can also maintain its stability when the support stud 13 is working. The support base 11 is fixedly mounted on the support structure 200 to maintain the overall structural stability of the micro-movement stage support device 100 and the structural stability of the atomizing device 100. The micro-motion stage support device 100 also includes a lifting sleeve 30, which is sleeved on the support stud 13 and can move up and down relative to the support stud 13. The end of the lifting sleeve 30 that faces away from the support seat 11 is fixedly abutted against the atomizer 300. When using a torque wrench, the lifting sleeve 30 can move up and down relative to the support stud 13 to adjust the height of the atomizer 300, thereby quickly adjusting the horizontal height of the atomizer 1000. By providing a scale 133 on the support stud 13, the scale 133 has graduations evenly spaced along the axial direction of the support stud 13. During the adjustment process, the rotation angle of the lifting sleeve 30 can be precisely controlled according to the scale 133 to adjust its horizontal height in real time, thereby adjusting the horizontal height of the atomizer 300 and the atomizer 1000. It can be known that the scale point of the scale 133 is based on the connection between the support stud 13 and the jacking sleeve 30 as the zero point, and the scale is set along the axial direction of the support stud 13, which facilitates the precise control of the rotation angle of the jacking sleeve 30 during the process of rotating to rise and fall, so as to adjust its horizontal height in real time, thereby completing the adjustment of the horizontal height of the atomizing tank 300 and the atomizing device 1000. When the sealing ring 400 needs to be replaced or adjusted, it is only necessary to adjust the micro-motion stage support structure 100 so that the position of the atomizing tank 300 changes, thereby reducing the time required to replace the sealing ring 400, while ensuring the performance of the sealing ring 400 when the atomizing tank 300 is working, which can ensure the smooth progress of the production process in the atomizing tank 300, thereby obtaining metal powder of good quality.

[0044] Reference Figures 1 to 3 In one embodiment of the present application, the lifting sleeve 30 can be configured as follows:

[0045] An end of the lifting sleeve 30 facing away from the supporting seat 11 is provided with a mounting groove 31 , a bottom wall of the mounting groove 31 is provided with a through hole 311 , an inner wall of the through hole 311 is provided with a thread 311 a , and the supporting stud 13 is screwed to the thread 311 a .

[0046] By providing a mounting groove 31 at the end of the lifting sleeve 30 facing away from the support base 11, the lifting sleeve 30 can be partially abutted against the atomizer 300. The bottom wall of the mounting groove 31 is provided with a through hole 311, and the inner wall of the through hole 311 is provided with a threaded section, and the support stud 13 is screwed to the threaded section. Through the screw connection between the two, the lifting sleeve 30 can be raised and lowered relative to the support stud 13 to adjust the height of the atomizer 300, thereby quickly adjusting the horizontal height of the atomizer device 1000. It is understood that the material of the lifting sleeve 30 can be rubber or other materials, which are not limited here.

[0047] Reference Figures 1 to 3 In one embodiment of the present application, the micro-motion stage support device 100 includes a ball bearing 50, the bottom surface of the ball bearing 50 abuts against the bottom wall of the mounting groove 31, and the top surface of the ball bearing 50 is used to fixedly abut against the atomizer tank 300.

[0048] It can be known that the ball bearing 50 is a spherical alloy steel ball installed between the inner and outer steel rings, which reduces the friction during power transmission and improves the transmission efficiency of mechanical power in a rolling manner.

[0049] By providing a ball bearing 50 with its bottom surface abutting the bottom wall of the mounting groove 31 and its top surface fixedly abutting the atomizer tank 300, the ball bearing 50 bears the pressure from the atomizer tank 300, thereby reducing the circumferential pressure on the adjustment sleeve 30 during rotation, making operation easier and more convenient for the operator. Furthermore, the provision of the ball bearing 50 also enables low-friction, high-precision movement, reducing the intensity of adjustment.

[0050] Reference Figures 1 to 3 In one embodiment of the present application, the lifting sleeve 30 is provided with an adjustment hole 33 , and the adjustment hole 33 is provided on the outer periphery of the lifting sleeve 30 .

[0051] An adjustment hole 33 is provided on the outer periphery of the lifting sleeve 30. When the height of the atomizer can 300 needs to be adjusted, a torque wrench can be inserted into the adjustment hole 33 and rotated to rotate the lifting sleeve 30 up or down, thereby adjusting the height of the atomizer can 300 and the atomizer device 1000. It is understood that the adjustment hole 33 does not need to intersect with the through hole 311, that is, it is arranged along the radial direction of the lifting sleeve 30 but does not pass through the lifting sleeve 30; such an arrangement can reduce the difficulty of operation for the operator during operation, making the operation easier and more convenient for the operator.

[0052] Reference Figures 1 to 3Furthermore, in one embodiment of the present application, there are multiple adjustment holes 33 , and the multiple adjustment holes 33 are evenly spaced along the circumference of the lifting sleeve 30 .

[0053] It is understood that the number of adjustment holes 33 can be multiple, and in this embodiment, eight adjustment holes 33 can be selected, and the eight adjustment holes 33 are evenly spaced along the circumference of the lifting sleeve 30. By providing eight adjustment holes 33 and arranging them evenly, the difficulty of adjusting the height of the atomizing tank 300 and the atomizing device 1000 can be further reduced. At the same time, a torque wrench can be used to accurately adjust the force state of each support point to achieve force balance between the various support points, ensuring that the entire atomizing device 1000 is in an optimal state when in a horizontal state.

[0054] It can be known that in other embodiments of the present application, the number of the adjustment holes 33 can also be four, six or other numbers, which is not limited here.

[0055] Reference Figures 1 to 3 In one embodiment of the present application, a threaded hole 131 is provided at one end of the support stud 13 facing away from the support seat 11, and the micro-motion stage support device 100 further includes a centering bolt 70, a gasket 80 and a washer 90. The centering bolt 70 passes through the atomizer tank 300 and is screwed into the threaded hole 131, and part of the centering bolt 70 is located in the mounting groove 31; the gasket 80 abuts against the atomizer tank 300; the washer 90 is provided between the centering bolt 70 and the gasket 80, and abuts against the bolt head of the centering bolt 70.

[0056] By providing the washer 90 and the gasket 80, and placing the gasket 80 against the atomizer tank 300, the washer 90 is disposed between the centering bolt 70 and the gasket 80, and abuts against the bolt head of the centering bolt 70. This can reduce wear on the centering bolt 70 when connected to the atomizer tank 300, thereby extending the service life of the centering bolt 70. It is understood that the material of the washer 90 and the gasket 80 can be elastic rubber or other elastic and flexible materials, which are not limited here.

[0057] It can be understood that by passing the centering bolt 70 through the atomizer tank 300 and connecting it to the threaded hole 131 of the support stud 13, the micro-motion stage support device 100 can serve as a middle connection to connect the atomizer tank 300 and the support structure 200, thereby reducing the time for adjusting the height of the atomizer tank 300 and the atomizer device 1000 and improving work efficiency.

[0058] Reference Figures 1 to 3 In one embodiment of the present application, the support base 11 can be configured as follows:

[0059] The support base 11 is provided with a plurality of first mounting holes 111 , which are evenly spaced along the circumference of the support base 11 . A bolt passes through the first mounting hole 111 and is screwed to the support structure 200 of the atomization device 1000 .

[0060] By setting the first mounting hole 111, the support seat 11 and the support structure 200 can be connected by bolts, which is equivalent to the micro-motion stage support device 100 serving as an intermediate connection to connect the atomizer tank 300 and the support structure 200, further reducing the time for adjusting the height of the atomizer tank 300 and the atomizer device 1000, thereby improving work efficiency.

[0061] It is understood that by providing multiple first mounting holes 111 and arranging them evenly spaced along the circumference of the support base 11, the stability of the connection between the support base 11 and the support structure 200 can be improved, thereby improving the structural stability of the fine-motion stage support device 100 during adjustment, and also improving the overall structural stability of the atomizer tank 300, the support structure 200, and the atomizer device 1000. In this embodiment, the number of first mounting holes 111 can be four.

[0062] The present invention further provides an atomization device 1000 , comprising an atomization tank 300 , a support structure 200 , and at least two of the aforementioned fine-motion stage support devices 100 . One fine-motion stage support device 100 is fixedly mounted on the support structure 200 and connected to the atomization tank 300 .

[0063] The atomizing device 1000 of the present application includes at least two of the aforementioned micro-movement support devices 100, thereby maintaining structural stability during height adjustment. The specific structure of the atomizing device 1000 of the present application refers to the above-mentioned embodiments. Since the atomizing device 1000 of the present application adopts all the technical solutions of all the above-mentioned embodiments, it has at least all the beneficial effects brought about by the technical solutions of the above-mentioned embodiments, which will not be described in detail here.

[0064] Reference Figures 1 to 2 In one embodiment of the present application, the support structure 200 may be configured as follows:

[0065] The support structure 200 includes a fixing frame 201, a first supporting platform 203, and a second supporting platform 205. The fixing frame 201 forms a receiving space 201a. The first supporting platform 203 is located at the top of the fixing frame 201 and is connected to the atomizing tank 300.

[0066] The second supporting platform 205 is disposed on the fixing frame 201 and is located below the first supporting platform 203 . The fine motion stage supporting device 100 is installed on the second supporting platform 205 .

[0067] The provision of the fixing frame 201 can maintain the overall stability of the support structure 200, and the accommodating space 201a formed by the fixing frame 201 can be used to accommodate the atomizer tank 300. The first support platform 203 is provided at the top of the fixing frame 201 and is connected to the atomizer tank 300. The second support platform 205 is provided on the fixing frame 201 and is located below the first support platform 203. The fine-motion stage support device 100 is mounted on the second support platform 205. By first connecting the atomizer tank 300 to the first support platform 203 and then mounting the fine-motion stage support device 100 on the second support platform 205, the force applied to the fine-motion stage support device 100 during adjustment can be reduced, making operation and adjustment more convenient, while also maintaining the structural stability of the fine-motion stage support device 100 and the atomizer device 100.

[0068] Reference Figures 1 to 2 In one embodiment of the present application, the atomizing tank 300 may be configured as follows:

[0069] The atomizing tank 300 includes a tank body 301, a first support plate 303 and a second support plate 305. The tank body 301 includes a first tank body 301a, a second tank body 301b and a discharge piece 301c. The first tank body 301a is connected to the second tank body 301b, and the second tank body 301b is connected to the discharge piece 301c. The sealing ring 400 is sleeved on the connection between the first tank body 301a and the second tank body 301b and the second tank body 301b and the discharge piece 301c; the first tank body 301a is provided with a feed port 307 on the side facing away from the second tank body 301b, and the discharge piece 301c is provided with a discharge port 309 on the end facing away from the second tank body 301b. The feed port 307 is connected to the discharge piece 301c. The material port 309, and the material inlet 307 and the material outlet 309, the material inlet 307 is close to the first support platform 203, and the material outlet 309 is close to the second support platform 205; the first support plate 303 is arranged along the circumference of the first tank body 301a, and the second support plates 305 are arranged along the circumference of the second tank body 301b. The first support plate 303 is provided with a second mounting hole, and a bolt passes through the second mounting hole and is screwed to the first support platform 203; the second support plate 305 is provided with a third mounting hole, and the centering bolt 70 of the micro-motion stage support device 100 passes through the third mounting hole and is screwed to the threaded hole 131 of the support stud 13; a sealing ring 400 is arranged between the first support plate and the second support plate.

[0070] Because the atomizing tank 300 is long, large in size and weight, if it is produced as a whole, a large amount of materials is required and the production process is relatively difficult. In this application, the tank body 301 of the atomizing tank 300 is divided into three parts: a first tank body 301a, a second tank body 301b, and a discharge piece 301c for processing and assembly. The connection between the first tank body 301a, the second tank body 301b, and the discharge piece 301c can be welded or other integrally formed connection methods. By sleeve-mounting the sealing ring 400 at the connection between the first tank body 301a and the second tank body 301b and the connection between the second tank body 301b and the discharge piece 301c, the air pressure inside the tank body 301 can be maintained when the high-temperature molten metal is sprayed into the tank body 301, giving the high-temperature molten metal sufficient time and space to be atomized and cooled into metal powder, which is then passed through the discharge piece 301c to the discharge port 309 for collection. When the user finds a leak in the tank body 301, the user adjusts the micro-stage support device 100 downward to separate the first tank body 301a and the second tank body 301b, so that the sealing ring 400 can be installed or adjusted to make the connection between the first tank body 301a and the second tank body 301b tightly connected, so that the high-temperature metal liquid has sufficient air pressure and space for atomization.

[0071] By adjusting the micro-motion table support device 100 upward, the second tank body 301b is separated from the discharge piece 301c, which facilitates the installation and debugging of the sealing ring 400. By providing two sealing rings 400, the sealing performance of the tank body 301 can be enhanced. At the same time, it can play a sealing and shock-absorbing role when the tank body 301 is working, and the workload of the overall installation and debugging of the atomization device is reduced, the work efficiency is improved, and good quality metal powder can be obtained.

[0072] The feed port 307 is connected to the front-end process of the atomizing device 1000. The high-temperature molten metal is sprayed by the air flow through the feed port 307 and enters the tank body 301. The high-temperature molten metal is atomized into small liquid drops and atomized and cooled in the tank body 301 to form metal powder.

[0073] The first support plate 303 is provided with a second mounting hole, which is used to be screwed to the threaded hole of the first support platform 203. The second support plate 305 is provided with a third mounting hole, which is screwed to the threaded hole of the fine-motion stage support device 100 through the centering bolt of the fine-motion stage support device 100. Through such an arrangement, the force applied to the fine-motion stage support device 100 during adjustment can be reduced, making operation and adjustment more convenient, and the structural stability of the fine-motion stage support device 100 and the atomization device 1000 can also be maintained.

[0074] It can be known that the first support plate 303 and the second support plate 305 are evenly arranged along the circumference of the atomizer tank 300. In this embodiment, the number of the first support plates 303 and the second support plates 305 can be selected as four, and the number of the second mounting holes can be selected as five. The five second mounting holes correspond to the threaded holes of the first support platform 203, and the bolts pass through the five second mounting holes and are screwed to the threaded holes of the five first support platforms 203.

[0075] In one embodiment of the present application, the discharge member 301c is configured in a funnel shape.

[0076] By setting the discharge piece 301c to be funnel-shaped, it is more convenient to collect the metal powder, and it also prevents the high-temperature metal liquid that has not been completely atomized from quickly and directly entering the discharge piece 301c.

[0077] In one embodiment of the present application, the atomization device 1000 further includes a powder collecting tank, which is connected to the discharge port 309 .

[0078] The high-temperature molten metal is sprayed into the atomizing tank 300 by the air flow, and after sufficient atomization and cooling spheroidization, metal powder is formed. By setting up a powder collecting tank, the metal powder falls from the discharge piece 301c to the discharge port 309 into the powder collecting tank due to gravity, thereby completing the preparation of the metal powder.

[0079] The present invention also provides a 3D printing powder preparation device, including the above-mentioned atomization device 1000. It can be understood that the 3D printing powder preparation device here includes vacuum induction atomization powder making equipment, electrode induction atomization powder making equipment, plasma atomization powder making equipment, radio frequency plasma spheroidization powder making equipment, ultrasonic atomization powder making equipment, etc., which are not limited here. The 3D printing powder preparation device of the present application includes the above-mentioned atomization device 1000, so that the structural stability when adjusting the height can be maintained. The specific structure of the 3D printing powder preparation device of the present application refers to the above-mentioned embodiment. Since the 3D printing powder preparation device adopts all the technical solutions of all the above-mentioned embodiments, it has at least all the beneficial effects brought about by the technical solutions of the above-mentioned embodiments, which will not be repeated here.

[0080] The above description is only a preferred embodiment of the present invention and does not limit the patent scope of the present invention. All equivalent structural transformations made by using the contents of the present invention description and drawings under the inventive concept of the present invention, or direct / indirect application in other related technical fields are included in the patent protection scope of the present invention.
