[0025] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0026] like Figures 1 to 11 As shown in the embodiment of this utility model, a chassis subframe casting post-processing system is provided, including a sand removal and trimming device, and a riser cutting and product inspection device located to the right of the sand removal and trimming device. The sand removal and trimming device includes a hammering workstation 1, a core remover 2 located to the right of the hammering workstation 1, and a trimming machine 3 located behind the core remover. The riser cutting and product inspection device includes a circular saw 4, a band saw 6 located behind the circular saw 4, a milling machine 5 located to the right of the circular saw 4, and an aluminum casting inspection X-ray machine 7 located behind the milling machine 5. A first conveyor 8 is provided between the sand removal and trimming device and the riser cutting and product inspection device.

[0027] like Figure 1 and Figure 2As shown, it also includes robotic arm 1 (9), robotic arm 2 (10), robotic arm 3 (11), robotic arm 4 (12), and a transfer table (13). Robotic arm 1 (9) is located to the right rear of the hammering workstation 1 and to the left front of the trimming machine 3. Robotic arm 1 (9) is used to move the chassis subframe to the hammering workstation 1 for hammering, then to the core remover 2 to remove residual sand, to the trimming machine 3 to remove burrs, and finally to the first conveyor 8. The transfer table 13 is located to the right rear of the circular saw 4 and to the left front of the aluminum casting inspection X-ray machine 7. Robotic arm 2 (10) is located between the circular saw 4 and the transfer table 13. Between the transfer station 13, robotic arm 2 10 is used to transfer the chassis subframe from the first conveyor 8 to the circular saw 4 for processing, and then to the transfer station 13; robotic arm 3 11 is located between the band saw 6 and the transfer station 13, and is used to transfer the chassis subframe from the transfer station 13 to the band saw 6 for processing; robotic arm 4 12 is located between the milling machine 5 and the aluminum casting inspection X-ray machine 7, and is used to transfer the chassis subframe from the transfer station 13 to the milling machine 5 for processing, and then to the aluminum casting inspection X-ray machine 7 for inspection and internal defect detection.

[0028] like Figure 3 As shown, the hammering workstation 1 includes a hammering platform 101, with a pneumatic hammer frame 102 hinged to one side of the hammering platform 101. Multiple pneumatic hammers 103 capable of downward hammering are mounted on the pneumatic hammer frame 102. A cylinder 104 is mounted on one side of the hammering platform 101 to drive the pneumatic hammer frame 102 to rotate. During hammering, the chassis subframe is first placed on the pneumatic hammer frame 102. Then, the pneumatic hammer frame 102 rotates, causing the pneumatic hammers 103 to rotate directly above the chassis subframe. The pneumatic hammers then start hammering the chassis subframe, causing residual sand inside the product to fall off. After the hammering contact, the pneumatic hammer frame 102 is rotated away from the chassis subframe, and then the chassis subframe is removed.

[0029] like Figure 4 As shown, the core remover 2 includes a frame 201, the top of which is hinged to the middle of a connecting frame 202; a power motor 203 is mounted on the frame 201 to drive the connecting frame 202 to rotate, and the power motor 203 is connected to the connecting frame 202 in a transmission manner; a vibration motor 204 is fixedly connected to the bottom of the connecting frame 202; the core remover 2 is used to discharge residual sand from the chassis subframe; when the core remover 2 is working, the chassis subframe is first fixed on the frame 201, then the frame 201 rotates and tilts at a certain angle; finally, the vibration motor 204 vibrates to discharge the residual sand from the chassis subframe; the frame 201 rotates and rotates to different angles, which is conducive to the smooth discharge of residual sand.

[0030] like Figures 5-7As shown, the trimming machine 3 includes an upper trimming die 301 with a cutter, a lower trimming die 302 that supports and limits the product, and a press 303 that drives the upper trimming die 301 to move. When the trimming machine 3 is working, the chassis subframe is placed on the lower trimming die 302 to support and limit the product, and then the trimming machine 3 drives the upper trimming die 301 to press down and cut off the burrs of the chassis subframe.

[0031] like Figures 8-10 Due to the complex shape of the riser and gate of the chassis subframe product, in order to meet the requirements of the residual height of the inner gate cutting, a circular saw 4, a milling machine 5, and a band saw 6 are used to cut and remove the riser and gate of the product.

[0032] The linkage methods of the devices in the above embodiments are as follows:

[0033] 1. The robotic arm 9 grabs the chassis subframe casting to the hammering workstation 1, and the equipment automatically hammers it;

[0034] 2. The robotic arm 9 grabs the casting and places it into the core remover 2, where the equipment automatically discharges the residual sand;

[0035] 3. The robotic arm 9 picks up the casting and places it onto the edge trimming machine 3, where the machine automatically trims the edges.

[0036] 4. The robotic arm 9 picks up the casting and places it onto the first conveyor 8. The first conveyor 8 automatically feeds the casting into the riser cutting and product inspection device.

[0037] 5. The robotic arm 210 picks up the casting and places it onto the circular saw 4 for cutting. After cutting, it is placed on the transfer table 13.

[0038] 6. The robotic arm 11 grabs the casting and moves it to the band saw 6 for cutting. After cutting, it is placed on the transfer table 13.

[0039] 7. The robotic arm 412 grips the casting and moves it to the milling machine 5 for processing. After processing, it is placed in the aluminum casting inspection X-ray machine 7.

[0040] 8. The robotic arm 412 removes the casting.

[0041] like Figure 1 , Figure 2 and Figure 11As shown; in some embodiments, it also includes a loading single-arm crane 14 and a loading turntable 15 located to the left of the hammering workstation 1, and two unloading conveyors 16 and an unloading single-arm crane 17 located to the right of the milling machine 5; the loading single-arm crane is used to lift the chassis subframe to one end of the loading turntable 15, and the worker scans the chassis subframe on one side, and the product information is automatically stored in the MES system. Then the loading turntable rotates 180° to rotate the chassis subframe to a position close to the robotic arm 9, so that the robotic arm 9 can grab and move the chassis subframe; the two unloading conveyors 16 are used to transport qualified products and unqualified products respectively. After passing through the aluminum casting inspection X-ray machine 7, the product is judged to be qualified. Then the robotic arm 12 transports the product to the corresponding unloading conveyor 16, and the unloading single-arm crane 17 is used to unload the product from the unloading conveyor 16.

[0042] like Figure 1 and Figure 2 As shown, in some embodiments, a core remover 2 is also provided behind the hammering workstation 1; the two hammering workstations 1 work together to improve work efficiency.

[0043] This embodiment integrates multiple processing equipment such as a hammering workstation, core remover, edge trimmer, circular saw, band saw, milling machine, and aluminum casting inspection X-ray machine. Through a reasonable layout, the entire chassis subframe casting post-processing system is compact, and the operation of adjacent equipment does not interfere with each other. The close spacing between multiple processing equipment enables effective connection. After a product is processed on one equipment, it can be directly transferred to the next equipment, reducing unnecessary transfers, minimizing the risk of product collisions, and ensuring product quality.

[0044] The technical advantages of the chassis subframe casting after-treatment system in this embodiment include:

[0045] ① Reduced labor costs: The traditional process requires 9 people: 2 for core removal, 2 for edge trimming, 2 for sawing, and 3 for X-ray inspection. In this embodiment, the required personnel are 3: 1 for loading, 1 for unloading, and 1 for inspection. This reduces labor costs to 33% of the original cost.

[0046] ② Reduction of transfer time and improvement of quality: In this embodiment, all processes are combined into one system. Material transfer is completed in a limited space by conveyors and robotic arms, saving 100% of transfer time, eliminating the number of transfers, and avoiding certain uncertainties in the transfer process.

[0047] ③ Space saving: The site area occupied by this embodiment is greatly reduced, with no buffer area or loading and unloading space, and the overall site occupancy can be reduced by more than 2 times;

[0048] ④ Traceability effectiveness: Traditional processes involve varying degrees of rework, resulting in poor traceability and easy material mixing. The chassis subframe casting post-processing system in this embodiment can effectively avoid multi-process rework problems, significantly reduce the number of code scanning traceability times, and greatly improve traceability effectiveness.

[0049] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art.
