[0002] The automobile air conditioning duct refers to the channel used to guide and distribute cold (or hot) air in the air conditioning system. It transmits the cold (or hot) air generated by the air conditioning system from the air conditioning unit to various areas of the vehicle, such as the feet, face and top of the driver and passengers. In the manufacturing process of automobile air conditioning ducts, the production process of air conditioning ducts is generally to use blow molding first, then cut the two ends with a sawing machine, then trim, and finally install the bracket and paste the sponge.

[0003] After searching, the Chinese patent with announcement number: CN205928776U discloses an automobile air-conditioning duct cutting tool, which can quickly complete the cutting of the automobile air-conditioning duct, avoids the trouble of cutting with a sawing machine and then trimming, avoids the debris generated by the sawing machine cutting from entering the duct, greatly improves the uniformity of the final product size, improves work efficiency, and improves both the output and quality of the product.

[0004] The working principle of the above patent states that “the air duct 2 is placed on the cutting tool, the upper part of the air duct 2 is placed in the air duct placement opening 9 of the support platform 8, and is initially clamped and positioned by the air duct clamping block 10, and is further positioned by the lower left positioning block 37, and the lower part of the air duct 2 is initially positioned by the lower right positioning block 34, such as Figure 2 The state shown, and then press the start button on the stand 1; the left support plate cylinder 4 and the right support plate cylinder 5 work, respectively pressing the left lower support plate 20 and the right lower support plate 13 downward, the left lower support plate 20 descends along the left guide column 14, the right lower support plate 13 descends along the right guide column 11, the left upper positioning block 36 descends to press against the upper part of the air duct 2, and the right upper positioning block 35 descends to press against the lower part of the air duct 2, and at the same time, the left upper mold 26 and the right upper mold 30 also descend, respectively cooperating with the left lower mold 27 and the right lower mold 31, as shown in FIG. Figure 3In the state shown, the left blade cylinder 3 and the right blade cylinder 6 start working at the same time, driving the left blade and the right blade to cut respectively. After cutting, the air duct 2 is removed and put into the turnover basket; the trouble of cutting with a sawing machine and then trimming is avoided, and the debris generated by the sawing machine cutting is avoided from entering the air duct, which greatly improves the uniformity of the final product size, improves the work efficiency, and improves the output and quality of the product.

The outer thread of the threaded tube 32 is threadedly connected to the adjusting ring 33, and the control box 34 is fixedly connected to the right side of the top of the operating table 1. The outer part of the air duct body 35 contacts the front side of the main clamping block 29 and the rear side of the slave clamping block 31. The air duct body 35 is placed in the middle position between the slave clamping block 31 and the main clamping block 29, and the adjusting ring 33 is rotated on the outside of the threaded tube 32. The adjusting ring 33 is rotated to drive the threaded tube 32 and the long rod 30 to slide in the middle part of the main clamping block 29, which can shorten the distance between the slave clamping block 31 and the main clamping block 29, that is, the two sides of the air duct body 35 are clamped and fixed.

[0032] Working principle: first place the air duct body 35 between the slave clamp block 31 and the main clamp block 29, and then rotate the adjusting ring 33 outside the threaded tube 32, so that the adjusting ring 33 rotates to drive the threaded tube 32 and the long rod 30 to slide in the middle of the main clamp block 29, shortening the distance between the slave clamp block 31 and the main clamp block 29, thereby clamping and fixing both sides of the air duct body 35.

[0033] After the air duct body 35 is fixed, the adjusting block 25 is rotated to loosen the adjusting rod 24, so that the adjusting rod 24 can slide in the slot block 23, thereby driving the support plate 21 to rotate through the adjusting rod 24 sliding in the slot block 23, thereby indirectly adjusting the lateral angle of the trimming gear 22, and then cooperating with the loosening of the adjusting block 28 to allow the adjusting rod 27 to drive the longitudinal angle of the square plate 20, so as to specifically adjust the cutting angle of the trimming gear 22. After the angle of the trimming gear 22 is adjusted, the control box 34 controls the motor 4 fixed on the sleeve 3 to start driving the threaded rod 5 to rotate the slider 6 fixed on the transmission sleeve 7 to slide horizontally and the motor 28 on the sleeve 7 to start the rotation of the threaded rod 29 to drive the support block 11 to slide longitudinally, so that the trimming gear 22 fixed on the support block 11 can move freely in the horizontal and longitudinal directions, and then cooperates with the control of the hydraulic cylinder 16 to drive the linkage rod 17 to extend and retract, so that the trimming gear 22 extends downward to accurately trim the outer side of the adjusting block 25.
