Description

Technical Field

[0001] This utility model relates to the field of casting extension arm technology, specifically an extension arm for a casting robot. Background Technology

[0002] With the rapid development of industrial automation, industrial robots have been widely used in the molten metal casting process.

[0003] A search revealed a patent, CN211614298U, which discloses a dedicated extended arm for a casting robot. This extended arm includes a dedicated extended arm, a drive mechanism, a harmonic reducer, a sprocket and chain transmission mechanism, a mounting base, and a rotating shaft. One end of the extended arm has a connecting part for connection with the sixth axis of the casting robot, and the other end has a mounting base. The drive mechanism is mounted on the extended arm, the harmonic reducer is installed inside the extended arm, and the rotating shaft is rotatably connected to the mounting base. A sprocket and chain transmission mechanism is provided between the rotating shaft and the harmonic reducer. Installing the harmonic reducer inside the extended arm reduces interference with the arm's movement and improves its service life. The drive mechanism independently drives the rotating shaft, meaning the rotation of the ladle is controlled by an independent drive mechanism, solving the problem caused by the ladle occupying the sixth axis of the casting robot.

[0004] The aforementioned patents have significant beneficial effects, but in practical application, they still have the following shortcomings:

[0005] The aforementioned comparative documents achieve the effect of extending the arm of the casting robot by fixing a longer extension arm to one end. However, in reality, the installation position of each casting robot is different, requiring the installation of extension arms of different lengths. This necessitates customization of the extension arm, reducing the applicability of the casting extension arm. Therefore, there is an urgent need in the field to improve the extension arm for casting robots to overcome the shortcomings of the existing technology. Utility Model Content

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0029] Example 1

[0030] Please see Figures 1-6 An extended arm for a casting robot includes a main robot arm 1, a fixed extended arm 2 at one end of the main robot arm 1, a movable extended arm 3 slidably connected to the fixed extended arm 2 at one end of the fixed extended arm 2, a casting ladle 4 at one end of the movable extended arm 3, a first drive motor 5 at one end of the movable extended arm 3 for driving the movable extended arm 3 to move on the fixed extended arm 2, a second drive motor 6 on one side of the movable extended arm 3 for driving the casting ladle 4 to rotate, a first sliding groove 7 adapted to the movable extended arm 3 on one side of the fixed extended arm 2, a sliding block 8 fixedly installed on one side of the movable extended arm 3, and a sliding block 8 formed on the inner wall of the first sliding groove 7. The second sliding groove 9 is adapted to block 8. The inner wall of the second sliding groove 9 is rotatably connected to a drive screw 10 that is threadedly connected to the sliding block 8. The first drive motor 5 drives the drive screw 10 to rotate. One end of the movable extended arm 3 is rotatably connected to a rotating shaft 11 that extends to the outside of the opposite side of the movable extended arm 3. Both ends of the rotating shaft 11 are fixedly mounted with connecting plates 12. A connecting frame 13 connected to the two connecting plates 12 is fixedly mounted on one side of the casting spoon 4. The movable extended arm 3 is hollow. The output end of the second drive motor 6 extends into the movable extended arm 3. Both the output end of the second drive motor 6 and the side of the rotating shaft 11 are fixedly mounted with sprockets. A chain for driving is provided between the sides of the two sprockets.

[0031] In this embodiment, the robot main arm 1 is fixedly installed at a designated casting position when casting is required. The robot main arm 1 is a known technology and can move at multiple angles. When the length of the extended arm needs adjustment, the first drive motor 5 is activated. The output of the first drive motor 5 drives the drive screw 10 to rotate. When the drive screw 10 rotates, it drives the sliding block 8 to move within the second sliding groove 9. The sliding block 8 drives the movable extended arm 3 to move within the first sliding groove 7, adjusting the position of the movable extended arm 3 on the fixed extended arm 2. This achieves the effect of adjusting the overall length of the extended arm, improving the casting efficiency. The extended arm of the robot is applicable to the following: the casting spoon 4 is installed between the ends of the two connecting plates 12 via the connecting frame 13. When it is necessary to transfer the casting solution, the robot's main arm 1 moves the casting spoon 4 into the casting solution, and the second drive motor 6 is started. The sprocket on the side of the output end of the second drive motor 6 drives the chain to rotate, the chain drives the sprocket on the side of the rotating shaft 11 to rotate, the rotating shaft 11 rotates accordingly, the rotating shaft 11 drives the connecting plate 12 to rotate, the connecting plate 12 drives the connecting frame 13 to rotate, and drives the casting spoon 4 to move, thereby realizing the transfer of the casting molten metal. It is worth noting that the above-mentioned sprocket and chain transmission is a known technology and is not shown in the figure.

[0032] Example 2

[0033] Please see Figure 2 , Figure 3 and Figure 5 This embodiment includes the above embodiment, and further includes: the number of casting spoons 4 is one or more, and the side of the connecting plate 12 away from the rotating shaft 11 and the opposite side of the connecting frame 13 are provided with polygonal positioning slots 15. Positioning pins 14 adapted to the positioning slots 15 are provided between two connecting plates 12 and one connecting frame 13 or two connecting plates 12 and several connecting frames 13. A locking threaded rod 16 is passed through the positioning pin 14, and a locking nut 17 is threaded to one end of the locking threaded rod 16.

[0034] In this specific embodiment, the number of casting ladles 4 can be one or more, achieving the capacity to transfer the molten casting in one go. When installing one casting ladle 4, the connecting bracket 13 on the casting ladle 4 is placed between two connecting plates 12, and the positioning slots 15 on the connecting bracket 13 and the connecting plates 12 are aligned. A positioning pin 14 of suitable length is selected and inserted into the positioning slot 15. The locking threaded rod 16 passes through the positioning pin 14, and the locking nut 17 is threaded onto one end of the locking threaded rod 16. The locking nut 17 is then tightened. This installs one casting ladle 4. If several casting ladles 4 need to be installed, the several casting ladles 4 are arranged in order... Figure 3Position the locating pin 14 according to its length, insert the locating pin 14 into the locating slot 15, and pass the locking threaded rod 16 of the appropriate length through several locating slots 15 and lock it with the locking nut 17. This facilitates the installation or replacement of one or several casting spoons 4.

[0037] In this embodiment, the height of the fixed column 18 can be customized according to the range of movement space of the robot main arm 1. The output end of the third drive motor 19 drives the robot main arm 1 to rotate horizontally, thereby increasing the range of movement of the robot main arm 1. The robot is installed and fixed to the ground by fasteners through the mounting plate 20.
