Description

Technical Field

[0001] The utility model belongs to the field of casting robots, and in particular relates to a copper liquid casting robot specially used for casting copper rotors. Background Art

[0002] In the field of electric motor manufacturing, cast copper rotors are core components of electric motors, and the copper casting process is crucial. Traditionally, this process relies heavily on manual labor, which is not only labor-intensive and inefficient, but also poses numerous safety hazards. For example, operators are prone to burns when handling hot copper crucibles, and it is difficult to ensure uniformity and accuracy during the casting process, which in turn affects the quality of the rotor.

[0003] To overcome these problems, some automated or semi-automated casting equipment has gradually emerged on the market. However, these devices often have limitations in design and functionality. For one thing, they may not be able to adapt to crucibles of varying shapes and sizes, resulting in unstable or even impossible clamping. Furthermore, they lack adequate cushioning and vibration reduction mechanisms during handling and casting, easily causing damage to the crucible and rotor.

[0004] Specifically, existing casting equipment may lack sufficient flexibility and precision in the design of the robotic arm, making it impossible to accurately transport the crucible to the designated location and stably clamp it. Furthermore, the clamping mechanism cannot effectively prevent the crucible from shaking or falling during handling. Furthermore, during the casting process, due to the lack of effective buffering and shock absorption measures, the high-temperature copper liquid may exert excessive impact on the crucible and rotor, leading to quality problems such as cracks and deformation. Utility Model Content

[0014] A linkage rod, telescopically sliding inside the support frame;

[0034] The copper molten casting robot specially used for copper rotor casting of the present invention will be described in more detail below with reference to the accompanying drawings and through specific implementation methods.

[0035] In the description of the present invention, it should be understood that the terms "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inside", "outside", etc., indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings. They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction. Therefore, they cannot be understood as limitations on the present invention.

[0036] This embodiment discloses a copper casting robot for copper rotor casting, which has obvious limitations in adapting to different crucible shapes and sizes, clamping stability, and buffering and shock absorption during transportation, resulting in low casting accuracy, high risk of damage, and frequent quality problems. Figure 1-6 The robot mainly comprises a robot arm body 1, on which a clamping member body 2 is connected. A buffer clamping member 3 is symmetrically mounted on the clamping member body 2 for safely and stably clamping the crucible.

[0037] The buffer clamp 3 is symmetrically mounted on the clamp body 2. This buffer clamp 3 can effectively absorb and disperse the impact and vibration from the copper liquid casting process while clamping the crucible. This design not only protects the crucible from damage, but also ensures a smooth casting process, avoiding production accidents caused by the crucible shaking or falling off.

[0038] In order to improve the automation level and operation accuracy of the copper rotor casting process, refer to Figure 1-2 The robot body 1 specifically includes a rotating disk 101 and a first robot arm 102. The first robot arm 102 is rotatably mounted on top of the rotating disk 101. A second robot arm 103 is rotatably connected to the first robot arm 102. A drive motor 104 has an output end fixed to the gripper body 2 and is connected to an end of the second robot arm 103 away from the first robot arm 102.

[0039] Transmission mechanism of the robotic arm body:

[0040] Rotating disk 101 and first robotic arm 102: Rotating disk 101 serves as the base of the entire robotic arm and is connected to the bottom of first robotic arm 102 via internal gears or bearings. When an external drive source (such as a motor) is activated, rotating disk 101 drives the first robotic arm to rotate in a horizontal plane, enabling a wide range of positioning adjustments.

[0041] First robotic arm 102 and second robotic arm 103: First robotic arm 102 is internally equipped with a transmission mechanism (such as a gear set, chain, or belt) that transmits the rotational or telescopic motion of first robotic arm 102 to second robotic arm 103. Furthermore, a rotary joint is provided at the end of second robotic arm 103, allowing it to rotate within a certain range, further increasing operational flexibility.

[0042] In order to further improve the crucible's clamping stability and adaptability during the casting of the copper rotor, the precise clamping and adaptive adjustment of the crucible are achieved by integrating the electric telescopic cylinder, the support frame and the innovative linkage mechanism, ensuring the smooth progress of the casting process. Figure 1 and Figure 3-4 The clamping member body 2 includes an electric telescopic cylinder 201 and a support frame 202. One end of the electric telescopic cylinder 201 is fixed to one end of the support frame 202. A linkage rod 206 slides telescopically within the support frame 202. A connecting plate 205 is hinged at one end to each end of the linkage rod 206. One end of each connecting plate 205 is hinged to the other end of the connecting plate 205 from top to bottom. The other end of the support plate 203 is rotatably connected to the buffer clamp 3.

[0043] The support frame 202, serving as the main framework of the clamp, not only provides a stable mounting platform for the electric telescopic cylinder but also features an internal slideway for the telescopic movement of the linkage rod 206. The ends of the linkage rod 206 are hinged to one end of two connecting plates 205. This articulation allows the connecting plates to adjust their angles when driven by the electric telescopic cylinder, thereby driving the movement of the entire clamping mechanism.

[0044] The connecting plate 205 is a key transmission component of the clamping mechanism. Its other end is hinged from top to bottom to the support plate 203 and one end of the adjustment plate 204. The adjustment plate 204 provides additional freedom for the clamping process through its adjustable angle, allowing the main body of the clamping member 2 to better adapt to crucibles of different shapes and sizes.

[0045] During the casting process, the stable clamping of the crucible is not only related to production safety, but also directly affects the casting quality. Figure 1 and Figure 5-6The buffer clamp 3 includes an arc-shaped clamping plate 301 and a buffer plate 302. The bottom of the buffer plate 302 is rotatably connected to the bottom of the arc-shaped clamping plate 301. The ball 303 is rotatably connected to the bottom of the inner wall of the buffer plate 302 and is hinged to the other end of the support plate 203 at the middle position of the arc-shaped clamping plate 301. One end of the arc-shaped clamping plate 301 is rotatably connected to the support frame 202. The outer surface of the ball 303 is provided with anti-slip grooves. The buffer clamp 3 includes: a limit plate 304, which is fixed to the outer surface of the arc-shaped clamping plate 301. The limit plate 304 corresponds to the buffer plate 302 and is inclined. A return spring 305 is fixed to the inner wall of the limit plate 304. The return spring 305 is connected to the outer wall of the buffer plate 302. The baffle 306 is fixed to the inner wall of the arc-shaped clamping plate 301 and is used to limit the buffer plate 302.

[0046] Ball bearings 303 are embedded in the bottom of the inner sidewall of buffer plate 302, reducing friction between the buffer plate and the curved clamping plate. The anti-slip texture on its outer surface also enhances the stability of the clamping. This design allows the buffer plate to quickly respond to impacts and disperse the force, thus minimizing damage to the crucible.

[0047] To further optimize the buffering effect and control the range of motion of the buffer plate, a combination of a limit plate 304 and a return spring 305 is introduced. The limit plate 304 is fixed to the outer surface of the arc-shaped clamping plate and corresponds to the buffer plate. Its inclined design not only helps guide the direction of movement of the buffer plate, but also increases the stability of the structure. The return spring 305 is connected to the inner wall of the limit plate 304 at one end and to the outer wall of the buffer plate 302 at the other end. When the buffer plate 302 is impacted and deviates from its original position, the return spring 305 can provide a reverse elastic force to quickly return the buffer plate 302 to its original position, ensuring the stability of the clamping.

[0048] In addition, the arrangement of the baffle 306 further enhances the structural strength of the buffer clamp. It is fixed to the inner side wall of the arc-shaped clamping plate 301 and effectively limits the buffer plate 392 to prevent it from accidentally falling off or being damaged when subjected to excessive impact.

[0049] The working principle of the copper liquid casting robot for copper rotor casting of the present invention is as follows: When the device is used, the copper sheet is placed in a crucible and melted in a furnace. After melting, the crucible needs to be taken out by the robot, and the copper liquid in the crucible is poured into the laminating machine for laminating and shaping. First, the rotating disk 101 is started to drive the first robot arm 102 and the second robot arm 103 to rotate to the corresponding positions in the furnace, and the first robot arm 102 and the second robot arm 103 are adjusted to move the clamping part body 2 to the outer surface of the crucible, and then the electric telescopic cylinder 201 is started. The output rod on the electric telescopic cylinder 201 drives the linkage rod 206 to retract, and the linkage rod 206 drives the connecting plate 205 to rotate, and the connecting plate 205 drives the support plate 203 and the adjustment plate 204 to rotate at the same time. The adjustment plate 204 limits and supports the rotation position of the support plate 203 and the connecting plate 205. The support plate 203 drives the arc-shaped clamping plate 301 to retract to clamp the crucible. First, the ball 303 It contacts the outer surface of the crucible, and then the arc-shaped clamping plate 301 clamps the top of the outer surface of the crucible, and then the crucible is moved to the film press by the robot arm main body 1, and then the drive motor 104 is started, and the drive motor 104 drives the clamping part main body 2 to rotate, and the copper liquid in the crucible is poured into the film press, and then the crucible is moved to the corresponding position outside by the robot arm main body 1 to wait. When the crucible falls in the buffer clamping part 3, the arc-shaped clamping plate 301 gradually opens, and then the crucible slides down, and the buffer plate 302 is pushed by the pressure of the reset spring 305. The ball 303 on the buffer plate 302 limits the descending speed of the crucible, slows down the descending speed of the crucible, and reduces the damage to the crucible.
