Description

A flexible automated deburring device Technical Field

[0001] This utility model relates to the field of deburring technology for metal die castings, and in particular to a flexible automated deburring processing device. Background Technology

[0002] In the die casting industry, the edges and corners of metal die castings often develop burrs, sharp points, and other sharp edges due to mold design defects (such as parting line gaps), poor material flow, or excessive processing pressure. In severe cases, the burrs may even cut or puncture other objects.

[0003] A deburring device for metal die castings is currently available, typically comprising a chassis and a clamping assembly and a grinding assembly respectively spaced apart within the chassis. The clamping assembly is used to clamp the metal die casting. However, in practical implementation, the inventors have found that the aforementioned grinding assembly adopts a single-spindle structure, requiring machine downtime to change the grinding head to accommodate rough grinding, fine grinding, polishing, and other processes. Furthermore, its machining freedom is limited, resulting in machining blind spots for complex metal die castings, necessitating manual re-clamping for supplementary processing, leading to low deburring efficiency. Additionally, the aforementioned clamping assembly uses fixed tooling, which can only clamp a single workpiece, exhibiting poor versatility and failing to meet the deburring needs of multiple batches of different workpieces. Summary of the Invention

[0004] Therefore, it is necessary to provide a flexible automated deburring processing device to achieve efficient and flexible processing of complex metal die castings, effectively improving production capacity and processing quality.

[0005] The technical solution of this utility model to solve the above-mentioned technical problems is as follows: A flexible automated deburring processing device includes a chassis and a clamping assembly and a grinding assembly respectively spaced apart within the chassis.

[0015] The second swing arm has one end rotatably connected to the second rotating arm, and the other end is equipped with a rotary motor, the output shaft of which is connected to the rotating platform.

[0016] In one embodiment, the fork has two parallel fork arms, the motor is fixed to the outer side of one of the fork arms, and the swing platform is disposed between the two fork arms.

[0019] By adopting the above technical solution, the present invention has at least the following beneficial effects: The present invention integrates the following clamping components and grinding components in the chassis to achieve flexible processing.

[0027] In one embodiment, as shown in Figures 1-3, a flexible automated deburring device includes a housing 1 and a clamping assembly 2 and a grinding assembly 4 respectively spaced apart within the housing 1. The clamping assembly 2 is used to clamp a metal die-casting part (not shown in the figures).

[0028] The clamping assembly 2 includes a fork 21, a motor 22 fixed on the fork 21, a swing platform 23 pivotally connected to the fork 21 via the motor output shaft of the motor 22, and a linkage clamping member 24 provided on the swing platform 23.

[0029] The grinding assembly 4 includes a base 41, a robotic arm 42 rotatably connected to the base 41, and three grinding head modules 43. The end of the robotic arm 42 is also provided with a rotary motor 421. The main shaft of the rotary motor 421 is connected to a rotary platform 422. The three grinding head modules 43 are arranged circumferentially on the rotary platform 422.

[0030] This embodiment of the invention integrates a clamping component 2 and a grinding component 4 within the chassis 1 to achieve flexible processing. Specifically, the clamping component 2 uses a fork 21 to fix a motor-driven swing platform 23, enabling continuous adjustment of a predetermined angle. Combined with a linkage clamping component 24 mounted on the swing platform 23, it can quickly clamp the metal die-casting parts and adjust their posture at a predetermined angle. The grinding component 4 uses a multi-degree-of-freedom robotic arm 42 as the grinding carrier. Its end integrates a rotary motor 421 to drive a rotary platform 422. The rotary platform 422 has three different sizes of grinding head modules 43 evenly distributed circumferentially. The robotic arm 42, in conjunction with the rotary platform 422, can perform compound actions, thus enabling precise removal of complex burrs from metal die-casting parts and switching between grinding processes. This achieves efficient and flexible processing of complex metal die-casting parts, effectively improving production capacity and processing quality.

[0031] In one embodiment, as shown in Figures 1-3, the linkage clamping component 24 is a clamping cylinder, which has four clamping blocks 240 movably arranged circumferentially to abut against the metal die-casting part. In this embodiment, the linkage clamping component 24 uses a clamping cylinder, and the four clamping blocks 240 retract inward to clamp the outer edge of the metal die-casting part, which can achieve stable clamping of metal die-casting parts with asymmetrical contours and has good applicability.

[0032] In one embodiment, as shown in Figures 1-3, each of the three grinding head modules 43 includes a driver 431, a chuck 432 connected to the spindle of the driver 431, and a grinding tool 433 mounted on the chuck 432. In this embodiment, the three grinding head modules 43, through their independent driver 431 and chuck 432 design, can be pre-assembled with the required grinding tools 433, and the grinding tools 433 can be flexibly switched according to actual processing needs to achieve grinding tasks of different processes, effectively improving process flexibility.

[0033] In one embodiment, as shown in Figures 1-3, the grinding tools 433 corresponding to the three grinding head modules 43 are a milling cutter, a rotary file, and a steel brush, respectively. In this embodiment, the milling cutter is suitable for initial machining scenarios, i.e., removing large areas of coarse and hard burrs (such as parting line burrs and gate residue); the rotary file is suitable for finishing scenarios, i.e., processing fine burrs on complex curved surfaces and hole edges (such as threaded holes and reinforcing rib junctions); and the steel brush is suitable for surface treatment scenarios, i.e., removing micro-burrs and oxide layers to improve surface finish. By configuring the above grinding tools 433, the flexible production needs of multiple varieties and small batches can be met.

[0034] In one embodiment, as shown in Figures 1-3, the robotic arm 42 includes:

[0035] A first rotating arm 423 connected to the base 41;

[0036] The first swing arm 424 is rotatably connected to the first rotating arm 423;

[0037] The second rotating arm 425; which is rotatably connected to the first swing arm 424; and

[0038] The second swing arm 426 has one end rotatably connected to the second rotating arm 425, and the other end is equipped with a rotary motor 421. The motor output shaft of the rotary motor 421 is connected to the rotating platform 422.

[0039] In this embodiment, by setting the above-mentioned structure, the robotic arm 42 can drive the grinding head module 43 to move to the position around the clamping component 2, and the rotating platform 422 can be rotated to the correct angle by the rotating motor 421, so as to better contact the corresponding grinding head module 43 with the edge of the metal die casting, thereby achieving the effect of removing burrs.

[0040] In one embodiment, as shown in Figures 1-3, the fork 21 has two parallel fork arms 210, the motor is fixed to the outer side of one of the fork arms 210, and the swing platform 23 is disposed between the two fork arms 210. In this embodiment, the fork 21 is configured with two parallel fork arms 210, the motor is fixed to one fork arm 210, and the swing platform 23 is correspondingly disposed between the two fork arms 210, which can reduce the material used in the fork 21 and facilitate assembly.

[0041] In one embodiment, as shown in Figures 1-3, a pullable transparent cover 11 is installed on the outside of the chassis 1. In this embodiment, by setting the pullable transparent cover 11, on the one hand, external dust and foreign objects can be prevented from entering the chassis 1, reducing the failure of internal components due to dust accumulation; on the other hand, it is convenient for operators to monitor the internal status of the chassis 1 in real time, and operators can observe without opening the cover, further reducing the risk of misoperation.

[0042] In one embodiment, as shown in Figures 1-3, the top of the chassis 1 is provided with a dust removal hood 12 having a dust removal interface 120, which is connected to an external dust removal system (not shown). In this embodiment, by connecting the dust removal interface 120 of the dust removal hood 12 on the top of the chassis 1 to an external dust removal system, it is possible to easily remove the debris generated after deburring the metal die-casting parts, thereby improving the processing quality.

[0043] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating this utility model, and are not intended to limit the implementation of this utility model. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively describe all embodiments here.
