Description

Technical Field

[0001] The utility model relates to the technical field of collaborative robots, and more specifically, to a collaborative processing robot for metal castings of numerically controlled machine tools. Background Art

[0002] In the collaborative processing of metal castings on CNC machine tools, collaborative robots can assist in completing some tedious, repetitive or potentially dangerous tasks for humans, such as parts handling, clamping, and testing. At the same time, through precise programming and control, collaborative robots can achieve seamless docking with CNC machine tools to ensure the accuracy and efficiency of the processing process.

[0003] On existing CNC lathes, clamping and disassembling workpieces are all done manually, which is time-consuming and laborious, and there are certain safety hazards.

[0004] After searching, the Chinese patent with publication number CN218134982U discloses a fully automatic loading and unloading device for serving CNC machine tools.

DETAILED DESCRIPTION

[0039] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0040] The embodiment of the present application discloses a collaborative processing robot for metal castings of a CNC machine tool, specifically comprising a centralizing platform 1, a mechanical arm 2 is installed on the left side of the top of the centralizing platform 1, and a clamping mechanism is fixedly connected to the top of the mechanical arm 2;

[0041] The clamping mechanism includes a fixed cylinder 3, a first motor 4 is fixedly connected inside the fixed cylinder 3, a gear 5 is coaxially connected to the output end of the first motor 4, two slot blocks 6 are fixedly connected to the outside of the fixed cylinder 3, two clamping plates 7 are movably connected to the bottom of the fixed cylinder 3, the two clamping plates 7 are symmetrically distributed on the outside of the fixed cylinder 3, two clamping blocks 8 are fixedly connected to the top of the two clamping plates 7, and multiple clamping blocks 8 are symmetrically distributed on the top of the two clamping plates 7. Slide grooves 9 are provided inside the two clamping plates 7, and toothed plates 10 are movably connected inside the two clamping plates 7. One end of the two toothed plates 10 is fixedly connected to a push plate 11, and the outsides of the two push plates 11 are fixedly connected to an arc clamping strip 12, and an insertion rod 13 is movably connected inside the two clamping plates 7, and a card column 14 is movably connected to the right end of the insertion rod 13. The two clamping plates 7 are clamped with the two slot blocks 6 at the bottom of the fixed cylinder 3 through the card block 8 at the top, and then the two clamping plates 7 are further fixed by the insertion rod 13 and the card column 14. During the maintenance process, the disassembly speed can be accelerated.

[0042] Reference Figure 5 As shown, specifically, a second motor 15 is fixedly connected inside the concentrating platform 1, and a turntable 16 is coaxially connected to the output end of the second motor 15 to rotate multiple plug plates 17 on the top to facilitate the collection of metal castings.

[0043] Reference Figure 6 As shown, specifically, a plurality of plug plates 17 are movably connected to the top of the turntable 16, a first spring 18 is fixedly connected to the bottom side of each of the plurality of plug plates 17, and a limiting ball 19 is fixedly connected to the bottom end of each of the first springs 18, so as to facilitate pulling out the plug plates 17 from the inside of the turntable 16.

[0044] Reference Figure 6 As shown, specifically, multiple limit rods 20 are movably connected to the tops of multiple plug plates 17, second springs 21 are movably connected to the outer sides of multiple limit rods 20, discs 22 are fixedly connected to the tops of multiple second springs 21, and multiple guide rods 23 are fixedly connected to the tops of multiple plug plates 17 to cushion the falling metal castings.

[0045] Reference Figure 1 As shown, specifically, the tops of the plurality of guide rods 23 are fixedly connected with anti-collision blocks 24 , so that the metal casting can accurately fall onto the guide rods 23 .

[0046] The working principle of the utility model is as follows: after the CNC machine tool completes the processing of the metal casting, the mechanical arm 2 drives the fixed cylinder 3 to move, the first motor 4 inside the fixed cylinder 3 drives the gear 5 to rotate, and the gear 5 drives the toothed plates 10 inside the two clamping plates 7 to move to both sides. During the process of the two toothed plates 10 moving in opposite directions, the two push plates 11 and the arc-shaped clamping strips 12 at the bottom are driven to move. When the two arc-shaped clamping strips 12 clamp the processed metal casting, the mechanical arm 2 drives the fixed cylinder 3 and the clamped metal casting to move to the top of the turntable 16, aligning the metal casting with the anti-collision block 24, and then the first motor 4 drives the two arc-shaped clamping strips 12 through the gear 5 to loosen the metal casting, and the metal casting falls to the top of the disc 22 through the anti-collision block 24 and the guide rod 23, and then falls. During the process, the falling metal castings are buffered by multiple limit rods 20 and the second spring 21, so as to reduce the impact of the falling metal castings on the centralizing platform 1 and the turntable 16. After the arc-shaped clamping strip 12 is clamped for a long time, the clamping column 14 perpendicular to the insertion rod 13 is rotated, so that the insertion rod 13 can be pulled out from the inside of the two clamping plates 7, and then the clamping blocks 8 on the top of the two clamping plates 7 are pulled out from both sides of the two slot blocks 6, so that the two toothed plates 10, the push plates 11 and the arc-shaped clamping strip 12 can be quickly removed for easy replacement. When the collected metal castings need to be transferred, the insertion plate 17 is pulled outward, so that the limit ball 19 compresses the first spring 18 and enters the inside of the insertion plate 17, and the guide rod 23 filled with metal castings can be pulled out from the top of the turntable 16 for easy movement.
