The positions and shapes of the upper card slots 61 and the lower card slots 41 correspond to each other one by one.

[0019] Through the above technical solution, when using this equipment to process the joint of the automotive air-conditioning pipeline, first place the automotive air-conditioning pipeline in the corresponding lower card slot 41 of the positioning seat 4 according to the model of the automotive air-conditioning pipeline. Then start the equipment. At this time, the lifting table descends, driving the upper seat 6 to descend until the upper seat 6 abuts against the positioning seat 4. At this time, the automotive air-conditioning pipeline is completely located within the upper card slot 61 and the lower card slot 41. Then the cutting tool 2 moves to cut the end of the automotive air-conditioning pipeline to complete the processing. Then the lifting seat 5 ascends. Then remove the processed automotive air-conditioning pipeline, and place the unprocessed automotive air-conditioning pipeline. Repeat the above steps to process the next automotive air-conditioning pipeline.

[0020] Multiple groups of upper card slots 61 and lower card slots 41 are applicable to automotive air-conditioning pipelines of multiple specifications. The shapes and positions of the lower card slots 41 and the upper card slots 61 on different positioning seats 4 and upper seats 6 are different. The positioning seat 4 and the upper seat 6 can be replaced according to the peak and off-peak seasons of production, and the use is flexible.

[0021] During the process of placing the automotive air-conditioning pipeline, placing the automotive air-conditioning pipeline in the lower card slot 41 at the corresponding position is the processing position, without secondary adjustment, improving the efficiency.

[0022] During the cutting process, the automotive air-conditioning pipeline is completely fixed to avoid loosening, improving the stability during the cutting process.

[0023] As a specific improvement embodiment, a mark is provided in the lower card slot 41.

[0024] Through the above technical solution, the mark is used to confirm the model of the automotive air-conditioning pipeline corresponding to the lower card slot 41, and can quickly locate and place, further improving the production efficiency.

[0025] As a specific implementation of the improvement, lower positioning grooves 31 are provided on both sides of the cutting table 3. The cross-section of the lower positioning groove 31 is wedge-shaped. A lower receiving groove 42 is provided on the lower side of the positioning seat 4. The lower receiving groove 42 wraps the cutting table 3 and is slidably connected thereto. A lower closing plate 32 is provided on one side of the cutting table 3, and a lower locking hole 33 is provided on the other side. A lower bolt 331 is threadedly connected in the lower locking hole 33. The lower bolt 331 and the lower closing plate 32 both abut against the positioning seat 4.

[0026] Through the above technical solution, the positioning seat 4 is slidably connected to the cutting table 3, which is convenient for disassembly and installation, and has a large force-bearing area and high stability after installation. During disassembly and assembly, first unscrew the lower bolt 331, then remove the existing positioning seat 4, and then install another positioning seat 4. When the newly installed positioning seat 4 abuts against the lower closing plate 32, the installation is in place. Then, fix the lower bolt 331 in the lower locking hole 33 to complete the replacement, which is convenient and efficient.

[0027] The cross-section of the lower positioning groove 31 is wedge-shaped, with a large contact area and high stability after installation.

[0028] As a specific implementation of the improvement, upper positioning grooves 51 are provided on both sides of the lifting seat 5. The cross-section of the upper positioning groove 51 is wedge-shaped. An upper receiving groove 62 is provided on the upper side of the upper seat 6. The upper receiving groove 62 wraps the lifting seat 5 and is slidably connected thereto. An upper closing plate 52 is provided on one side of the lifting seat 5, and an upper locking hole 53 is provided on the other side. An upper bolt 531 is threadedly connected in the upper locking hole 53. The upper bolt 531 and the upper closing plate 52 both abut against the upper seat 6.

[0029] Through the above technical solution, the upper seat 6 is slidably connected to the lifting seat 5, which is convenient for disassembly and installation, and has a large force-bearing area and high stability after installation. During disassembly and assembly, first unscrew the upper bolt 531, then remove the existing upper seat 6, and then install another upper seat 6. When the newly installed upper seat 6 abuts against the upper closing plate 52, the installation is in place. Then, fix the upper bolt 531 in the upper locking hole 53 to complete the replacement, which is convenient and efficient.

[0030] The cross-section of the upper positioning groove 51 is wedge-shaped, with a large contact area and high stability after installation.
