Technical Field

[0001] This utility model relates to the field of automotive parts processing equipment technology, and in particular to a dual-axis positioning device for foam engraving and cutting automotive parts that is adapted to complex curved surfaces. Background Technology

[0002] In the automotive manufacturing industry, the research and development and production of complex curved surface parts often require the creation of foam models for verification and testing. The carving and cutting precision of the foam model directly affects the accuracy of subsequent part production.

[0003] Currently, when using tools such as foam cutting knives (electrothermal knives), jigsaws, and engraving knife sets for processing, a large amount of foam debris and a small amount of harmful gases are generated during the processing. The accumulation of debris not only pollutes the processing environment but may also enter the equipment and cause wear. The harmful gases also pose a threat to the health of operators. To address these issues, we propose a dual-axis positioning device for foam engraving and cutting of automotive parts that is adapted to complex curved surfaces. Utility Model Content

A support plate 4 is fixedly connected to the upper surface of the slewing bearing 3. A clamping mechanism 5 is fixedly connected to the upper surface of the support plate 4. A rotating mechanism 6 is fixedly connected to the upper surface of the housing 1. Multiple air intake holes 7 are opened on the upper surface of the support plate 4. A connecting pipe 8 is fixedly connected to the inner bottom wall of the housing 1. A fan 10 is fixedly connected to the inner wall of the connecting pipe 8. A support frame 9 is fixedly connected to the upper surface of the connecting pipe 8. A first bearing 11 is embedded in the upper surface of the support frame 9. A rotating frame 13 is fixedly connected to the inner ring of the first bearing 11. A second rotating frame 13 is fixedly connected to the bottom surface of the support frame 9. A motor 12 is fixedly connected to the outer surface of a rotating frame 13. A filter screen 14 is installed on the outer surface of the rotating frame 13. The filter screen 14 is mainly composed of three layers: the outermost layer is non-woven fabric or sponge, which can filter impurities such as debris or dust; the middle layer is activated carbon, which can absorb some toxic gases; and the innermost layer is a hogalat layer, which can absorb carbon monoxide. The negative pressure generated by the rotation of the fan 10 can draw debris or toxic gases into the outer shell 1 through the air intake 7. The rotating frame 13 and the filter screen 14 are rotated by the first motor 12, which can make the gas fully contact the filter screen 14 and avoid local saturation of the filter screen 14. The bottom surface of the support plate 4 and the upper surface of the partition plate 2 are fixedly connected to an electric slip ring, which can provide power to the clamping mechanism 5.

[0023] The clamping mechanism 5 includes two connecting plates 501. A second bearing 502 is embedded in the outer surface of each connecting plate 501. A threaded rod 503 is fixedly connected to the inner ring of each of the two second bearings 502. A second motor 504 is fixedly connected to the outer surface of one of the connecting plates 501. The output end of the second motor 504 is fixedly connected to the outer surface of the threaded rod 503. Two threaded blocks 505 are threadedly connected to the outer surface of the threaded rod 503. Two smooth rods 506 are fixedly connected to the outer surfaces of the two connecting plates 501. Each smooth rod 506 is slidably connected to each threaded block 505. A universal clamp 507 is fixedly connected to the upper surface of each threaded block 505. The second motor 504 drives the threaded rod 503 to rotate, which, combined with the smooth rods 506 providing support and guidance, allows the threaded blocks 505 and the universal clamp 507 to move closer together to clamp the foam. The universal clamp 507 can deform and lock according to the shape of the foam.

[0024] The rotating mechanism 6 includes a third motor 601. A third bearing 602 is embedded in the inner top wall of the housing 1.

A reinforcing rib 18 is fixedly connected to the upper surface of the housing 1. By setting the sealed door 16, it is convenient to clean or replace the filter screen 14. By setting the sealing ring 17, the inner side wall of the filter screen 14 contacts the outer ring of the sealing ring 17. With the sealing ring 17 engaged, air is prevented from entering the interior of the filter screen 14 from the bottom.

[0025] The working principle of this utility model is as follows:

[0026] When using this device, place the foam between the two connecting plates 501, control the second motor 504 to drive the rotating threaded rod 503, so that the threaded rod 503 drives the threaded block 505 and the universal clamp 507 to move closer to each other, so that the universal clamp 507 clamps the foam and locks the shape of the universal clamp 507. By controlling the third motor 601 to drive the gear rod 603 to rotate, the gear rod 603 drives the slewing bearing 3 and the support plate 4 to rotate, thereby driving the foam to rotate. When carving and cutting, turn on the fan 10, and the fan 10 creates a negative pressure inside the outer shell 1, which draws the broken foam and harmful gases into the outer shell 1 through the air intake 7. The first motor 12 drives the rotating frame 13 and the filter screen 14 to rotate, and the filter screen 14 filters the broken foam and harmful gases.
