Description

Technical Field

[0001] This utility model relates to the field of casting machine technology, and in particular to a three-point weighing three-axis linkage fully automatic casting machine. Background Technology

[0002] A casting machine is a type of mechanical equipment used in casting production or other specific production fields. Its main function is to precisely inject liquid metal (molten iron or molten steel) into a mold or a specific forming space to form the desired casting or product. This can improve the success rate of casting while reducing material waste and the risk of worker injury.

[0003] Traditional manual casting suffers from drawbacks such as high labor intensity, unstable quality, low efficiency, and harsh working conditions. Semi-automatic tilting casting machines involve manual operation of the equipment, but they cannot cast quantitatively. Manual operation is required to raise and lower the casting ladle, and personnel must identify whether the molten iron is full, making accurate quantitative casting impossible. Furthermore, they cannot meet the casting needs of sand boxes of different heights. Although current three-axis linkage casting machines on the market are equipped with weighing sensors and vision cameras to achieve automatic casting, the weighing devices are mostly four-point weighing devices. The weighing mechanism is placed under the transverse movement mechanism, and the overall tare weight of the weighing mechanism is very large (including the weight of transverse movement, lifting, tilting, and other components). Therefore, a large-range weighing sensor needs to be selected, resulting in a large error when the weighing device feeds back the weight of the molten iron that needs to be accurately measured. Utility Model Content

[0004] The purpose of this utility model is to provide a three-point weighing, three-axis linkage fully automatic casting machine to solve the above problems.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A three-point weighing, three-axis linkage fully automatic casting machine includes a casting ladle. A tilting block is fixedly connected to one side of the casting ladle. A movable block is installed on one side of the tilting block. A motor for driving the tilting block is installed on the movable block. A weighing device is installed at the bottom of the movable block. An electric lifting frame is installed on one side of the movable block. The weighing device is installed on one side of the electric lifting frame. A transverse moving bracket is installed at the bottom of the electric lifting frame. A longitudinal moving bracket is installed at the bottom of the transverse moving bracket. Motors are installed on both the transverse and longitudinal moving brackets. A side plate is fixedly connected to one side of the longitudinal moving bracket. An extension bracket is installed on the top of the side plate. Three vision cameras are installed on the extension bracket.

[0007] Preferably, a side bracket is fixedly connected to one side of the longitudinal moving bracket, and a sealing cover is installed on the side bracket.

[0008] Preferably, an identification sensor is installed on the top of the sealing cover.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figure 1-4 This utility model provides a technical solution:

[0022] like Figure 1-4 As shown, a three-point weighing, three-axis linkage fully automatic casting machine includes a casting ladle 1. A tilting block 2 for rotating the casting ladle 1 is fixedly connected to one side of the ladle 1. A movable block 3 for weighing the tilting block 2 and the casting ladle 1 on a weighing device 4 is installed on one side of the tilting block 2. A motor for driving the tilting block 2 is installed on the movable block 3. A weighing device 4 for weighing the molten iron is also installed on the movable block 3. The weighing device 4 includes a weighing sensor and three hooks for fixing the casting ladle 1. The weighing sensor can obtain the weight of the casting ladle 1 by the force borne by the three hooks. An electric lifting frame 5 for moving the casting ladle 1 up and down is installed on one side of each movable block 3. The weighing device 4 is installed on one side of the electric lifting frame 5. A transverse moving bracket 6 for driving the casting ladle 1 to move laterally is installed at the bottom of the electric lifting frame 5. A longitudinal moving bracket 7 is installed at the bottom of the transverse moving bracket 6. Motors are installed on both the transverse moving bracket 6 and the longitudinal moving bracket 7. The lateral moving bracket 6, the longitudinal moving bracket 7, and the electric lifting frame 5 are all driven by servo motors to move the casting ladle 1. The three axes of the lateral moving bracket 6, the longitudinal moving bracket 7, and the electric lifting frame 5 move simultaneously to ensure that the molten iron outlet point of the casting ladle 1 remains unchanged during pouring. A side plate 8 is fixedly connected to one side of the longitudinal moving bracket 7. An extension bracket 9 is installed on the top of the side plate 8. The bottom of the extension bracket 9 is equipped with a slide rail. The operator can drive the extension bracket 9 to move on the slide rail by the motor, thereby moving the three vision cameras 10. The extension bracket 9 is equipped with three vision cameras 10 for observing the liquid level and pouring situation inside the casting ladle 1. When the molten iron flows out of the casting ladle 1, the vision cameras 10 identify it and weigh it through the weighing device 4. The pouring process is controlled in real time by the weighing device 4, the vision cameras 10, and the operator. The value displayed on the weighing device 4 changes continuously. When the weight requirement of the casting is met, the operator controls the tilting block 2 to reverse at a certain angle to retract the casting ladle 1 and stop pouring out the molten iron.

[0023] like Figure 1 and Figure 4As shown, a side bracket 11 is fixedly connected to one side of the longitudinal moving bracket 7. A sealing cover 12 for sealing the casting ladle 1 is installed on the side bracket 11. An identification sensor 13 is installed on the top of the sealing cover 12. Because a casting machine is equipped with many casting ladles 1 for rotation, and different casting ladles 1 have certain differences in their coating, which may affect the accuracy and precision of automatic casting to varying degrees, the identification sensor 13 includes four trigger sensors. The position and number of trigger sensors that each casting ladle 1 can contact are different (e.g., casting ladle ① can only trigger trigger sensors 1 and 3, while casting ladle ② can trigger trigger sensors 2 and 3). Therefore, different trigger combinations can be used to identify which casting ladle 1 is being used. The casting bag 1 is running online, allowing staff to monitor its parameters and ensure more accurate casting. A buzzer 14 is installed on one side of the movable block 3, and is electrically connected to the motor that drives the tilting block 2. When the tilting block 2 rotates the casting bag 1, the buzzer 14 will sound to alert those nearby that the casting machine is in operation and that they should stay away from it. An incubation tank 15 for storing inoculant is fixedly connected to the top of the side plate 8. A conveying pipe 16 for discharging inoculant into the casting bag 1 is connected to one side of the incubation tank 15. A remote control valve is installed on the conveying pipe 16. The top of the incubation tank 15 has an inlet for replenishing the incubation tank 15 with new inoculant, and a sealing plug 17 is threadedly connected to the inner wall of the inlet.

[0024] Working Principle: In this embodiment, the three-point weighing, three-axis linkage fully automatic casting machine is used as follows: The casting ladle 1 is first installed on the tilting block 2. The horizontal moving support 6, the vertical moving support 7, and the electric lifting frame 5 lift the casting ladle 1 to the designated position. Simultaneously, the operator uses the identification sensor 13 to identify which casting ladle 1 is on the casting machine. Then, the motor drives the tilting block 2 to rotate, which in turn rotates the casting ladle 1, discharging the molten iron for casting. When the molten iron flows out of the casting ladle 1, the vision camera 10 identifies it, and the weighing device 4 performs weighing and counting. The casting process is monitored by the weighing device 4 and the vision camera 10. Camera 10 and staff observe and control the pouring process in real time. The weighing device 4 displays constantly changing values. When the weight requirement of the casting is met, the staff controls the tilting block 2 to reverse at a certain angle and retract the pouring ladle 1, stopping the pouring of molten iron. According to the needs of the production line, the staff continues to move the pouring ladle 1 to the next pouring station for pouring until the pouring work is completed. In this way, the pouring ladle 1 can be removed. During the pouring process, the staff can observe the molten iron condition of the pouring ladle 1 in real time and then remotely control the opening and closing of the conveying pipe 16 so that the inoculant in the inoculation box 15 can be quantitatively discharged into the interior of the pouring ladle 1 through the conveying pipe 16.

[0025] In summary, the weighing device 4 is designed on the tilting block 2, which greatly reduces the tare weight of the weighing mechanism (only the weight of the tilting block 2 and the movable block 3 is used), thus reducing the error in weighing molten iron. The weighing device 4 and three vision cameras 10 measure the instantaneous weight of the molten iron as it flows out of the ladle 1 and measure the change in the liquid level height of the molten iron in the pouring cup during the pouring process, thereby providing feedback to the operator. The operator can then adjust the tilting block to fine-tune the pouring speed of the ladle 1.
