[0002] After the production of the ports of corrosion-resistant air ducts, burrs are likely to remain on their surfaces, so a grinding device is needed to grind the ports of the corrosion-resistant air ducts. When the traditional grinding device grinds the ports of the air ducts, the fixing effect is poor, which easily causes the ports of the air ducts to shift and shake, resulting in a large error in the grinding size of the ports of the corrosion-resistant air ducts, reducing the accuracy of the air ducts and increasing the defective rate of air duct production.

[0003] Among them, the publication number CN213889360U discloses a port grinding device for the production and processing of metal air ducts, including a box body. Support legs are bolted to the four corners of the bottom of the box body. A metal air duct is placed at the center of the top of the box body. A fixing seat is bolted to the left side of the top of the box body, and a controller is bolted to the front of the fixing seat. A high-speed motor is bolted to the right side of the fixing seat, and a grinding blade is bolted to the output shaft of the high-speed motor. There are still defects in this technical solution:

[0004] After grinding one end of the air duct in this technical solution, it is necessary to release the limit on the air duct, then swap the positions of the two ends of the air duct, and then re-limit the air duct before the other end of the air duct can be ground. The operation process is very cumbersome, time-consuming and laborious. Content of the Utility Model

[0026] In order to enable those skilled in the art to better understand the technical solutions of the present utility model, the following will further introduce the present utility model in detail in conjunction with the drawings.

[0027] The embodiment of the present utility model discloses a grinding mechanism for processing corrosion-resistant air ducts.

[0028] Referring to Figures 1-3 , a grinding mechanism for processing corrosion-resistant air ducts includes a base plate 1 and a rotating rod 2. Two rotating rods 2 are rotatably sleeved at both ends of the base plate 1. A placing shell 3 is fixedly arranged at the upper end of the rotating rod 2. A strip-shaped opening is formed in the middle of the upper surface of the base plate 1. A slide block 4 is slidably arranged inside the strip-shaped opening. Both sides of the slide block 4 are in contact with the inner wall of the strip-shaped opening, so that the slide block 4 cannot rotate, that is, it can slide stably. A biaxial motor 5 is fixedly arranged on the upper side of the slide block 4. Grinding discs 6 are fixedly sleeved on both output ends of the biaxial motor 5;

[0029] Support plates 9 are fixedly arranged on both sides of the lower surface of the base plate 1. A worm 10 is rotatably arranged between the two support plates 9. Worm gears 11 are fixedly sleeved on the lower ends of the two rotating rods 2. The two worms 10 are meshed with the corresponding worm gears 11;

[0030] On the lower surface of the bottom plate 1 and on both sides of the slider 4, side plates 7 are fixedly arranged. A reciprocating lead screw 8 is rotatably arranged between the two side plates 7, and both ends of the reciprocating lead screw 8 are rotatably connected to the corresponding side plates 7.

[0031] Referring to Figures 1-3 , on the inner side of one side plate 7, a transmission mechanism for sequentially driving the reciprocating lead screw 8 and the worm 10 to rotate is arranged. The transmission mechanism includes spur gears 14 and an incomplete gear 16. The two spur gears 14 are respectively fixedly sleeved on one end of the corresponding reciprocating lead screw 8 and the worm 10. The incomplete gear 16 is arranged between the two spur gears 14. A transmission rod 15 is fixedly sleeved inside the incomplete gear 16. One end of the transmission rod 15 is rotatably connected to the corresponding side plate 7. A driving motor 17 is fixedly arranged on the outer side of the side plate 7. The output end of the driving motor 17 is fixedly connected to one end of the transmission rod 15. The incomplete gear 16 is meshed with the spur gear 14 on one side.

[0032] Referring to Figures 1-3 , on the upper side inside the placing shell 3, a clamping mechanism is arranged. The clamping mechanism includes a clamping plate 12 and a threaded rod 13. The threaded rod 13 is threadedly sleeved on the middle part of the upper side of the placing shell 3. The clamping plate 12 is slidably arranged inside the placing shell 3. The lower end of the threaded rod 13 is rotatably connected to the clamping plate 12. By rotating the threaded rod 13, the threaded rod 13 drives the clamping plate 12 to move, so as to clamp and limit the air duct inside the placing shell 3. Both sides of the clamping plate 12 are in contact with the inner wall of the placing shell 3, so that the clamping plate 12 cannot rotate, and thus can slide stably. A rubber pad is fixedly arranged on the lower surface of the clamping plate 12 to prevent the air duct from being clamped and damaged as much as possible.

[0033] In the present utility model, during use, the air duct is placed inside the placing shell 3, and then the threaded rod 13 is rotated. The threaded rod 13 drives the clamping plate 12 to move, so as to clamp and limit the air duct inside the placing shell 3. Then, the power supplies of the driving motor 17 and the double-shaft motor 5 are connected. The driving motor 17 drives the transmission rod 15 to rotate, so that the incomplete gear 16 rotates and meshes with the upper spur gear 14, that is, drives the upper spur gear 14 to rotate, and further enables the reciprocating lead screw 8 to drive the slider 4 to reciprocate. At the same time, the double-shaft motor 5 drives the two grinding discs 6 to rotate, so as to sequentially grind the ends of the air ducts on both sides, reduce the time wasted by the double-shaft motor 5 for resetting, and improve work efficiency. After one end is ground, the driving motor 17 drives the incomplete gear 16 to rotate until it meshes with the lower spur gear 14 (at this time, the slider 4 is at the middle of the strip-shaped opening, that is, the two grinding discs 6 are not in contact with the corresponding ends of the air ducts), that is, drives the worm 10 to rotate. The worm 10 drives the two worm wheels 11 to rotate, so that the two rotating rods 2 drive the corresponding placing shells 3 to rotate, so as to exchange the positions of the two ends of the air duct, without re-clamping the air duct, which is convenient to operate, time-saving and labor-saving.

[0034] Only some exemplary embodiments of the present utility model are described by way of illustration. Without doubt, for those of ordinary skill in the art, the described embodiments can be modified in various different ways without departing from the spirit and scope of the present utility model. Therefore, the above drawings and description are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present utility model.
