[0042] Example 1, please refer to Figure 1-Figure 7As shown, the telescopic swing arm includes a fixed arm 13 connected to a rotary drive mechanism 23. The fixed arm 13 has a working arm telescopic motor 3 and a mixing rotor motor 4 at one end, and a telescopic arm sleeved at the other end.

[0043] Specifically, the telescopic arm includes a first telescopic arm 14 and a second telescopic arm 15. One end of the first telescopic arm 14 is sleeved within the fixed arm 13, and the other end is sleeved within one end of the second telescopic arm 15. The other end of the second telescopic arm 15 is provided with a connector 34, which is provided with a first steering gear 31. The fixed arm 13, the first telescopic arm 14, and the second telescopic arm 15 are all hollow. The second telescopic arm 15 is sleeved within the cavity of the first telescopic arm 14, and the first telescopic arm 14 is sleeved within the cavity of the fixed arm 13.

[0044] Furthermore, a first stirring drive shaft 25 is provided in the fixed arm 13. One end of the first stirring drive shaft 25 is connected to the output shaft of the stirring rotor motor 3 through a coupling 24, and the other end is fitted with a second stirring drive shaft 26.

One end of the third stirring drive shaft 27 is fixed to the second telescopic arm 15, and the other end is connected to the first steering gear 31. The first stirring drive shaft 25, the second stirring drive shaft 26, the third stirring drive shaft 27, and the first steering gear 31 rotate synchronously under the drive of the stirring rotor motor 3. The stirring rotor motor 3 drives the first stirring drive shaft 25 to rotate, and the first stirring drive shaft 25 further transmits the rotational motion to the first steering gear 31 through the second stirring drive shaft 26 and the third stirring drive shaft 27.

[0045] Furthermore, a first screw rod 28 is provided in the fixed arm 13, one end of the first screw rod 28 is connected to the output shaft of the working arm telescopic motor 3 through a coupling 24, and the other end is connected to the first telescopic arm 14 through a first connecting member 29, the first connecting member 29 is provided with a first pulley 35, and the end of the first telescopic arm 14 away from the fixed arm 13 is provided with a second pulley 36, the fixed arm 13 is provided with a first fixed pile 37 at the end close to the working arm telescopic motor 3, and a second fixed pile 38 is provided at the end close to the first telescopic arm 14, the first fixed pile 37 is connected to the second chain 30, the other end of the second chain 30 passes around the second pulley 36 and is connected to the end of the second telescopic arm 15 close to the first telescopic arm 14, the second fixed pile 38 is connected to the third chain 33, the other end of the third chain 33 passes around the first pulley 35 and is connected to the end of the second telescopic arm 15 close to the first telescopic arm 14. The arm telescoping motor 4 drives the first screw 28 to rotate, causing the first connecting member 29 to translate on the first screw 28, thereby driving the first telescopic arm 14 to translate within the fixed arm 13. When the first telescopic arm 14 moves, the second telescopic arm 15 is pulled by the third chain 33, and the second chain 30 maintains the movement balance. This enables the first and second telescopic arms 14, 15 to move synchronously under the action of the arm telescoping motor 4, adjusting the length of the telescopic swing arm and thus the position of the tool, and the equipment occupies a small space. The first connecting member can be an internally threaded nut fixed to the first telescopic arm 14, and the internal thread mates with the first screw 28.

[0046] Further, see Figure 7 As shown, the first stirring drive shaft 25 adopts a hexagonal transmission shaft, and the internal cavity of the second stirring drive shaft 26 is a shape that matches the hexagonal transmission shaft. Such a structure allows the second stirring drive shaft 26 to slide along the first stirring drive shaft 25, and also allows the second stirring drive shaft 26 to rotate together with the first stirring drive shaft 25. It should be noted that the second stirring drive shaft 26 and the third stirring drive shaft 27 can also adopt a hexagonal transmission shaft, and the internal cavity of the third stirring drive shaft 27 is a shape that matches the second stirring drive shaft 26. Therefore, the third stirring drive shaft 27 can slide along the second stirring drive shaft 26, and also allow the third stirring drive shaft 27 to rotate together with the second stirring drive shaft 26.

[0047] Furthermore, the fixed arm 13 is provided with a storage tank 11, the discharge port of which is sealedly connected to one end of a delivery pipe 12. The delivery pipe 12 passes through the internal cavities of the fixed arm 13, the first telescopic arm 14, and the second telescopic arm 15, and then extends out of the second telescopic arm 15. The delivery pipe 12 is provided with a valve. The delivery pipe 12 is a telescopic pipe that can be extended and retracted along with the telescopic swing arm.

[0048] Example 2, please refer to Figure 8As shown, compared with the telescopic swing arm in Example 1 which is a three-section swing arm including a fixed arm 13, a first telescopic arm 14 and a second telescopic arm 15, the telescopic swing arm in this embodiment is a two-section swing arm including only a fixed arm 13 and a first telescopic arm 14. It has a simple structure, but the adjustment accuracy is slightly lower than that of Example 1.

[0049] Specifically, the telescopic arm includes a first telescopic arm 14, one end of which is sleeved within the fixed arm 13 and the other end of which is provided with a connector 34, which is equipped with a first steering gear 31. Both the fixed arm 13 and the first telescopic arm 14 are hollow, and the first telescopic arm 14 is sleeved within the cavity of the fixed arm 13. A first agitation drive shaft 25 is installed within the fixed arm 13. One end of the first agitation drive shaft 25 is connected to the output shaft of the agitation rotor motor 3 via a coupling 24, and the other end of the first agitation drive shaft 26 is sleeved. The second agitation drive shaft 26 is fixed to the first telescopic arm 14 at one end and connected to the first steering gear 31 at the other end. The first, second, and first steering gears 31 rotate synchronously under the drive of the agitation rotor motor 3. The agitation rotor motor 3 rotates the first agitation drive shaft 25, which then transmits the rotational motion to the first steering gear 31 via the second agitation drive shaft 26. A first screw rod 28 is provided in the fixed arm 13. One end of the first screw rod 28 is connected to the output shaft of the working arm telescopic motor 3 through a coupling 24, and the other end is connected to the first telescopic arm 14 through a first connecting member 29. The working arm telescopic motor 4 drives the first screw rod 28 to rotate, so that the first connecting member 29 translates on the first screw rod 28, thereby driving the first telescopic arm 14 to translate in the fixed arm 13, adjusting the length of the telescopic swing arm, and thus adjusting the position of the tool. The equipment occupies a small space.

[0050] Furthermore, the first stirring drive shaft 25 adopts a hexagonal transmission shaft, and the internal cavity of the second stirring drive shaft 26 is a shape that matches the hexagonal transmission shaft. Such a structure allows the second stirring drive shaft 26 to slide along the first stirring drive shaft 25, and also allows the second stirring drive shaft 26 to rotate together with the first stirring drive shaft 25.

[0051] Furthermore, the fixed arm 13 is provided with a storage tank 11, the discharge port of the storage tank 11 is sealedly connected to one end of a delivery pipe 12. The delivery pipe 12 passes through the internal cavity of the fixed arm 13 and the first telescopic arm 14, and then extends out of the first telescopic arm 14. The delivery pipe 12 is provided with a valve. The delivery pipe 12 is a telescopic pipe that can be extended and retracted along with the telescopic swing arm.

[0052] It should be noted that the telescopic arm may also be a multi-section swing arm comprising more than three sections, and the working principles of its rotational motion and telescopic motion are similar to those of the three-section swing arm.

[0053] Example 3, please refer to Figures 9-12 As shown, the telescopic swing arm includes a support frame 41 connected to a rotary drive mechanism, and four groups of support wheels distributed in a rectangular shape are mounted on the support frame 41, including two groups of upper support wheels 44 and two groups of lower support wheels 45. A movable arm 42 is provided between the upper support wheels 44 and the lower support wheels 45. One end of the movable arm 42 is connected to the support frame 41 through the upper support wheel 44 and the lower support wheel 45, and the other end is provided with a connecting head 34. A rotating shaft 43 is also provided between the movable arm 42 and the lower support wheel 45. The rotating shaft 43 is arranged parallel to the movable arm 42, and one end of the rotating shaft 43 is connected to the stirring rotor motor 4, and the other end is provided with a first steering gear 31 through the connecting head 34.

[0054] The movable arm 42 is provided with two symmetrically arranged hanging plates 47 on one side close to the rotating shaft 43. The hanging plates 47 are provided with a number of pins 48 equidistantly arranged along the length direction of the movable arm 42. A working arm telescopic motor 3 and a stirring rotor motor 4 are provided on one side of the support frame 41.

Two symmetrically arranged third sprockets 46 are sleeved on the output shaft of the working arm telescopic motor 3. The third sprocket 46 is engaged with the pin 48 on the hanging plate 47.

[0055] The working arm telescopic motor 3 is a reduction motor, and the output shaft drives the third sprocket 46. The third sprocket 46 pushes the pin shaft 48 engaged with it, so that the movable arm 42 can move in translation under the support of the upper support wheel and the lower support wheel, thereby adjusting the depth of the movable arm 42 extending into the aluminum melting furnace 17.

[0056] Specifically, the output shaft of the stirring rotor motor 4 is connected to a worm 49, which is mounted on the support frame 41 through a bearing. The worm 49 is engaged with the first turbine 410, and the rotating shaft 43 is mounted in the center of the first turbine 410. Preferably, the rotating shaft 43 adopts a hexagonal transmission shaft, and the center of the first turbine 410 is provided with a central groove that matches the shape of the hexagonal transmission shaft for the rotating shaft 43 to pass through. The stirring rotor motor 4 drives the worm 49 to drive the first turbine 410 to rotate. When the first turbine 410 rotates, it can synchronously drive the rotating shaft 43 to rotate. Because the rotating shaft 43 is connected to the movable arm 42 through the connector 34, when the movable arm 42 translates, it will drive the rotating shaft 43 to translate.

[0057] The movable arm 42 is provided with a conveying pipe 12, one end of the conveying pipe 12 extends out of the movable arm 42 to connect to the powder source, and the other end of the conveying pipe 12 extends out of the other end of the movable arm 42.

[0058] In some embodiments, such as embodiments 1 to 3, a numerical control system is also included. The numerical control system is associated with the walking mechanism 7, the lifting drive device, and the rotating drive mechanism 23 to achieve automatic control.

[0059] Specifically, the working arm telescopic motor 3, the stirring rotor motor 4, and the valves provided on the conveying pipe are all associated with the numerical control system.

The output shaft of the spindle lifting motor 5 is connected to a second screw rod 39. The spindle 2 is a hollow shaft. A second connecting member 40 is provided at the end of the spindle 2 near the spindle lifting motor 5, which mates with the second screw rod 39. The spindle 2 is sleeved outside the second screw rod 39. The spindle lifting motor 5 drives the second screw rod 39 to rotate, and the second connecting member 40 moves the spindle 2 up and down along the second screw rod 39 to adjust the height of the telescopic swing arm. The second connecting member 40 can be an internally threaded nut fixed to the spindle 2, the internal threads of which mate with the second screw rod 39.

[0061] In some embodiments, such as Examples 1-3, a second sprocket 21 is provided at one end of the travel mechanism 7. A translation motor 6 associated with a numerical control system is provided on the frame 1. A first sprocket 19 is provided on the output shaft of the translation motor 6. The first sprocket 19 and the second sprocket 21 are connected by a first chain 20. The translation motor 6 drives the first sprocket 19, which in turn transmits the second sprocket 21 via the first chain 20, causing the frame 1 to translate along the horizontal rail beam 8 and adjust the horizontal position of the frame 1. Limit blocks 9 are provided at both ends of the horizontal rail beam 8 to prevent the frame 1 from separating from the horizontal rail beam 8.

[0062] It should be noted that the walking mechanism 7 can also adopt a matching slide rail and slide groove structure, and a rack can be provided on the side of the horizontal rail beam 8. The output shaft of the translation motor 6 associated with the CNC system is provided with a gear that engages with the rack to drive the frame 1 to translate along the horizontal rail beam 8.

[0063] In some embodiments, the numerical control system can be a CNC numerical control system, which is provided with a control program to control the translation of the frame 1, the vertical translation of the telescopic swing arm, the extension and contraction of the telescopic swing arm, and the rotation of the telescopic swing arm. Sensors can also be provided in the furnace to feedback the page height and the temperature in the furnace to the CNC numerical control system, so as to adjust the height of the telescopic swing arm according to the liquid level, realize over-temperature alarm of the working arm and automatically terminate the operation, etc. A catcher can also be provided on the bottom surface of the slag scraper 162 to automatically capture the slag surface at the bottom of the furnace and feed it back to the CNC numerical control system to realize automatic slag cleaning. Sensors can also be provided at corresponding positions to feedback the powder spraying status, the translation status of the frame 1, the vertical translation status of the telescopic swing arm, the extension and contraction status of the telescopic swing arm, the rotation status of the telescopic swing arm, the inert gas pressure, etc. to the CNC numerical control system, and issue a jam alarm to indicate an operating malfunction.

[0064] In some embodiments, the connector 34 is connected to the stirring rotor 161 or the slag scraper 162 or the furnace cleaning scraper. The stirring rotor 161 , the slag scraper 162 and the furnace cleaning scraper are provided with a second steering gear 32 that meshes with the first steering gear 31 .

[0065] The retractable swing arm described in Example 1 is used for the stirring and refining process: the connector 34 is connected to the stirring rotor 161 for the stirring and refining process. The stirring rotor 161 is provided with a second steering gear 32 that meshes with the first steering gear 31. The stirring rotor 161 is mounted to the end of the second telescopic arm 15 via the connector 34 and is driven by the first steering gear 31.

[0066] The fixed arm 13 is provided with a material storage tank 11, the discharge port of which is sealedly connected to one end of a delivery pipe 12. The delivery pipe 12 passes through the internal cavities of the fixed arm 13, the first telescopic arm 14, and the second telescopic arm 15, and then extends out of the second telescopic arm 15 to connect to the powder delivery channel inside the mixing rotor 161. A powder injection valve is provided on the delivery pipe 12.

[0067] The position of the stirring rotor 161 within the aluminum melting furnace 17 is adjusted by the arm extension motor 4, the spindle lift motor 5, and the translation motor 6. The spindle rotation motor 22 also allows for fine-tuning of the stirring rotor 161's position within the aluminum melting furnace 17, ensuring a zero-dead-spot stirring operation. Powder can be sprayed into the aluminum melting furnace 17 simultaneously during stirring. The powerful stirring action of the stirring rotor 161 ensures rapid temperature change in the molten aluminum, preventing local overheating of the melt and accelerating the melting and dissolution of alloying elements. This reduces stirring time and energy loss, ensuring full absorption of alloy additives, minimizing auxiliary material consumption, reducing composition adjustment time, and minimizing alloy segregation.
