Description

Technical Field

[0001] This invention relates to the field of robotic arm technology, and in particular to a material handling device for high-temperature casting. Background Technology

[0002] In high-temperature casting production, after casting is formed, it needs to be removed from the die-casting machine and transferred to the next process. However, the castings are hot and heavy, and manual handling poses a risk of burns and is inefficient, making traditional material handling equipment a bottleneck in production. Existing material handling devices often have functional limitations: some can only move in one direction, making it difficult to flexibly adapt to the cross-equipment transfer needs between multiple die-casting machines; some have poor clamping structure stability, making them prone to loosening and falling off when gripping high-temperature castings, resulting in casting damage; and some devices cannot flexibly adjust the material handling height and angle, making it difficult to accurately align with the casting position inside the die-casting machine, requiring repeated adjustments and extending the material handling time. These problems not only affect the continuous operation efficiency of the casting production line, but also increase safety hazards, failing to meet the requirements for material handling flexibility, stability, and safety in high-temperature casting scenarios. Therefore, in response to the above situation, there is an urgent need to develop a high-temperature casting material handling device that can achieve multi-dimensional position adjustment through the lateral movement of the trolley, the forward and backward movement of the trolley, and the rotation of the turntable. It can also adjust the height and angle with the help of lifting and tilting cylinders, and use clamping cylinders to drive the grippers for stable clamping. This device can accurately complete the grabbing, transfer, and placement of high-temperature castings, adapt to the material handling needs of multiple casting equipment, and improve efficiency and safety, so as to overcome the shortcomings in current practical applications and meet current needs. Summary of the Invention

[0003] The purpose of this invention is to provide a material handling device for high-temperature casting, so as to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] A high-temperature casting material handling device includes a trolley, a carriage, a rotating mechanism, a gantry, a lifting frame, a tilting cylinder, a lifting cylinder, a forward / reverse mechanism, a clamping cylinder, a gripping mechanism, and a flipping mechanism. A long shaft is rotatably connected to the lower side of the trolley, and support wheels are fixedly mounted at both ends of the long shaft, supporting the ground. A drive motor and a reducer are fixed on the trolley; the output shaft of the drive motor is connected to the reducer, and the output shaft of the reducer is connected to the long shaft. A forward / reverse mechanism is mounted on the carriage, and the forward / reverse mechanism is in rolling contact with the trolley. A rotating mechanism is mounted on the carriage, and the rotating mechanism includes: The system comprises a turntable, a hydraulic motor, a gear shaft, and a large gear. The turntable is rotatably connected to a trolley. The hydraulic motor is fixed to the turntable, and its output shaft is fixedly connected to the gear shaft. A large gear meshing with the gear shaft is located on one side of the gear shaft, and the large gear is fixed to the outside of the turntable. The bottom of the tilting cylinder is hinged to the turntable, and the top of the tilting cylinder is hinged to the gantry. The lifting frame is slidably mounted on the gantry, with the bottom of the tilting cylinder fixed to the gantry and the top of the tilting cylinder fixed to the lifting frame. The flipping clamp mechanism is mounted on the lifting frame, and both the clamping cylinder and the gripping mechanism are mounted and connected to the flipping clamp mechanism.

[0006] Preferably, the forward and backward mechanism includes a three-in-one geared motor, a rotating shaft, a drive wheel, and guide wheels. The three-in-one geared motor is fixed on the trolley, the rotating shaft is rotatably connected to the trolley, the output shaft of the three-in-one geared motor is connected to the rotating shaft, drive wheels are fixed at both ends of the rotating shaft, the drive wheels are in rolling contact with the trolley, and multiple guide wheels are rotatably connected to both sides of the trolley, the guide wheels are in rolling contact with the trolley.

[0007] Preferably, the flipping clamp mechanism includes: a housing, a worm gear, a worm wheel, a hollow shaft, and a cycloidal motor. The housing is fixed to the lifting frame, and the worm gear is rotatably connected inside the housing. The cycloidal motor is fixed to the housing, and the output shaft of the cycloidal motor is fixed to the worm gear. A worm wheel that meshes with the worm gear is provided on the lower side of the worm gear, and the worm wheel is fixed to the outside of the hollow shaft. The hollow shaft is rotatably connected inside the housing.

[0008] Preferably, the clamping mechanism includes: grippers, pins, a first connecting piece, a second connecting piece, a push-pull rod, a connecting rod, and a clamping yoke cylinder. The clamping yoke cylinder is fixed to the front side of the chassis. There are two grippers arranged opposite to each other. The two grippers are rotatably connected to the clamping yoke cylinder by pins. The left end of each gripper is rotatably connected to a first connecting piece by a pin. The second connecting piece is rotatably connected to both first connecting pieces by pins, and the second connecting piece is rotatably connected to the connecting rod by pins. The left end of the connecting rod is fixed to the push-pull rod. The clamping cylinder is fixed to the rear side of the chassis. The piston rod of the clamping cylinder passes through a hollow shaft and is fixed to the left end of the push-pull rod.

[0009] The beneficial effects of this invention are as follows: When using this high-temperature casting material handling device, the clamping mechanism is first positioned against the high-temperature casting to be removed. Then, a three-in-one reduction motor drives the rotating shaft and drive wheel to rotate. The drive wheel rotation causes the trolley to move forward on the main carriage, allowing the clamping mechanism to enter the die-casting machine. A tilting cylinder then drives the lifting frame to move downwards, which in turn drives the clamping mechanism downwards, allowing the high-temperature casting to enter between the two jaws. A clamping cylinder then drives the push-pull rod and connecting rod to move. The connecting rod causes the two first and second connecting plates to swing, and the first connecting plates cause the jaws to swing, bringing the two jaws closer together to clamp the high-temperature casting. Finally, a tilting cylinder retracts, causing the gantry to deflect upwards. The gantry then drives the lifting frame and clamping mechanism to deflect upwards, thereby removing the casting. The high-temperature casting is lifted, and then the trolley is moved backward by the forward and backward mechanism to remove the high-temperature casting. Then, the drive motor drives the reducer, long shaft and support wheels to rotate, thereby driving the trolley to move laterally on the ground and move it close to the next die-casting machine. Then, the hydraulic motor drives the gear shaft and large gear to rotate, and the large gear drives the turntable to rotate on the trolley. The turntable drives the gantry, lifting frame and clamping mechanism to rotate. Then, the forward and backward mechanism drives the clamping mechanism to enter the next die-casting machine. The forward and backward mechanism then puts down the high-temperature casting and then exits. In addition, the cycloidal motor drives the worm gear to rotate, and the worm gear drives the worm wheel and hollow shaft to rotate. The worm wheel and hollow shaft drive the clamping cylinder and clamping mechanism to rotate up and down, so as to adjust the high-temperature casting by rotating it up and down. In summary, this invention achieves multi-dimensional position adjustment through the lateral movement of the large trolley, the forward and backward movement of the small trolley, and the rotation of the turntable. With the help of lifting and tilting cylinders to adjust the height and angle, and the clamping cylinders to drive the grippers for stable clamping, it can accurately complete the grabbing, transfer and placement of high-temperature castings, adapt to the material handling needs of multiple casting equipment, and improve efficiency and safety.

[0033] Working principle: In use, this high-temperature casting material handling device first aligns the clamping mechanism 11 with the high-temperature casting to be removed. Then, the three-in-one reduction motor 901 drives the rotating shaft 902 and drive wheel 903 to rotate. The rotation of the drive wheel 903 drives the trolley 3 to move forward on the large trolley 1, allowing the clamping mechanism 11 to enter the die-casting machine. Then, the tilting cylinder 7 drives the lifting frame 6 to move down, which in turn drives the clamping mechanism 11 to move down, allowing the high-temperature casting to enter the two grippers. Between 1101, the clamping cylinder 10 drives the push-pull rod 1105 and the connecting rod 1106 to move. The connecting rod 1106 drives the two first connecting plates 1103 and the second connecting plate 1104 to swing. The first connecting plate 1103 drives the gripper 1101 to swing, so that the two grippers 1101 move closer to each other to clamp the high-temperature casting. Then, the tilting cylinder 7 retracts, causing the gantry 5 to deflect upward. The gantry 5 drives the lifting frame 6 and the clamping mechanism 11 to deflect upward, thereby lifting the high-temperature casting. The high-temperature casting is removed by moving the trolley 3 backward via the forward / backward mechanism 9. Then, the drive motor 2 drives the reducer 201, long shaft 101, and support wheel 102 to rotate, thereby driving the trolley 1 to move laterally on the ground and approach the die-casting machine for the next process. Then, the hydraulic motor 402 drives the gear shaft 403 and the large gear 404 to rotate, and the large gear 404 drives the turntable 401 to rotate on the trolley 3. The turntable 401 drives the gantry 5, the lifting frame 6, and the clamping mechanism to rotate. The holding mechanism 11 rotates, and then the forward and backward mechanism 9 drives the clamping mechanism 11 into the next die-casting machine. The forward and backward mechanism 9 then puts down the high-temperature casting and exits. In addition, the cycloidal motor 1205 drives the worm gear 1202 to rotate, and the worm gear 1202 drives the worm wheel 1203 and the hollow shaft 1204 to rotate. The worm wheel 1203 and the hollow shaft 1204 drive the clamping cylinder 10 and the clamping mechanism 11 to rotate up and down, so as to adjust the high-temperature casting by rotating it up and down.
