[0024] The utility model is further described below in conjunction with the accompanying drawings:

[0025] like Figure 1-Figure 6As shown, a threading and locking screw machine for an air-conditioning chassis comprises a machine body 1, a workbench 2 is fixedly connected to the top of the machine body 1, a locking screw assembly 3, a tapping assembly 4, and a conveying mechanism 5 are installed on the top of the workbench 2, the conveying mechanism 5 is located at the rear side of the locking screw assembly 3 and the tapping assembly 4, a pressing mechanism 8 for fixing the air-conditioning chassis is arranged above the conveying mechanism 5, the pressing mechanism 8 spans the conveying mechanism 5 front and back, a limiting mechanism 6 is arranged above the conveying mechanism 5, the limiting mechanism 6 comprises a rear limiting plate 601 and two front limiting plates 602, the rear limiting plate 601 is located at the rear end above the conveying mechanism 5, the two front limiting plates 602 are slidably connected to the front end of the top of the conveying mechanism 5, the front limiting plate 602 can move along the length direction of the conveying mechanism 5, and the two front limiting plates 602 move in a direction away from each other, thereby leaving a gap for the locking screw assembly 3 and the tapping assembly 4 to process the air-conditioning chassis, and a power mechanism 7 for driving the rear limiting plate 601 to move forward and backward is installed on the top of the workbench 2.

[0026] The two front limit plates 602 are symmetrically arranged, and a connecting block 604 is fixedly connected to one end of the top of the front limit plate 602 near the pressing mechanism 8. Two symmetrically arranged first cylinders 603 are fixedly installed on the pressing mechanism 8. The output shafts of the two first cylinders 603 are respectively fixedly connected to the two connecting blocks 604. The first cylinder 603 is extended to drive the front limit plate 602 to move through the connecting block 604, so that the two front limit plates 602 are separated or closed. When the two front limit plates 602 are closed, it is convenient to move the air-conditioning chassis to the processing position. After the two front limit plates 602 are separated, the locking screw assembly 3 and the tapping assembly 4 can process the air-conditioning chassis. The opposite surfaces of the rear limit plate 601 and the front limit plate 602 are rotatably connected with multiple guide wheels 605, and the guide wheels 605 are used to facilitate the movement of the air-conditioning chassis.

[0027] The power mechanism 7 includes two screw rods 701, which are located at both ends of the conveying mechanism 5. The screw rods 701 are installed on the top of the workbench 2 through a bearing seat. A movable block 702 is connected to the screw rod 701 through a thread. The movable block 702 is fixedly connected to the top of the rear limit plate 601. The two screw rods 701 are driven through a synchronous belt assembly 703. Specifically, the synchronous belt assembly 703 includes two synchronous wheels and a synchronous belt. The two synchronous wheels are connected through a synchronous belt. The two synchronous wheels are respectively fixedly connected to the rear ends of the two screw rods 701, so that the two screw rods 701 can rotate synchronously. When the screw rod 701 rotates, the rear limit plate 601 is driven to move forward and backward through the movable block 702, and the distance between the rear limit plate 601 and the front limit plate 602 is adjusted to adapt to air-conditioning chassis of different widths. A drive motor 704 is installed at the rear end of the workbench 2 through a motor seat, and the output shaft of the drive motor 704 is connected to a screw rod 701 through a coupling.

[0028] The pressing mechanism 8 includes a fixed platform 801, which is fixedly installed on the top of the workbench 2 by a supporting rod. A slide groove is provided in the middle of the fixed platform 801, and a mounting seat 802 is slidably connected in the slide groove. The mounting seat 802 can move forward and backward along the slide groove. A pressing cylinder 803 is connected to the top of the mounting seat 802 by screws. A plurality of positioning grooves 804 are provided on the top of the fixed platform 801 and on both sides of the slide groove. A positioning rod 805 is inserted into the top of the mounting seat 802. The positioning rod 805 penetrates the mounting seat 802 and extends into the positioning groove 804. However, when the position of the pressing cylinder 803 needs to be moved, the positioning rod 805 is pulled out of the positioning groove 804 to make the mounting seat 802 move along the slide groove, and then the positioning rod 805 is inserted into the positioning groove 804 to fix the mounting seat 802. The position of the pressing cylinder 803 can be adjusted to adapt to air-conditioning chassis of different widths.

[0029] The conveying mechanism 5 includes two side plates 501, the side plates 501 are fixedly connected to the top of the workbench 2, a conveyor belt 502 is installed between the two side plates 501, a conveying motor 503 for driving the conveyor belt 502 to rotate is fixedly installed on the top of the workbench 2, and two front limit plates 602 are slidably connected to the top of the front side plate 501;

[0030] Working principle: when in use, the air-conditioning chassis is placed on the conveyor belt 502, and the conveyor motor 503 drives the conveyor belt 502 to rotate and convey the air-conditioning chassis to the processing position. During this process, the air-conditioning chassis is limited between the rear limit plate 601 and the front limit plate 602, so as to prevent the air-conditioning chassis from deflecting during movement, and the air-conditioning chassis contacts the guide wheel 605, and the guide wheel 605 facilitates the movement of the air-conditioning chassis. After the air-conditioning chassis moves to the processing position, the air-conditioning chassis is pressed by the pressing cylinder 803, and then the two first cylinders 603 respectively push the two front limit plates 602 away from each other, so that a gap is formed between the two front limit plates 602. At this time, the air-conditioning chassis corresponds to the gap position, and then the air-conditioning chassis can be processed by the locking screw assembly 3 and the tapping assembly 4. After the processing is completed, the two front limit plates 602 are closed, and the pressing cylinder 803 releases the fixation of the air-conditioning chassis, and then the conveyor belt 502 sends the air-conditioning chassis out.

[0031] For air-conditioning chassis of different widths, a screw rod 701 is driven to rotate by a driving motor 704, and the screw rod 701 drives another screw rod 701 to rotate synchronously through a synchronous belt assembly 703, and the screw rod 701 drives the movable block 702 to move, and the movable block 702 drives the rear limit plate 601 to move forward and backward, thereby adjusting the distance between the rear limit plate 601 and the front limit plate 602 to adapt to air-conditioning chassis of different widths, and the positioning rod 805 is pulled out of the positioning groove 804, and the moving mounting seat 802 adjusts the front and rear position of the pressing cylinder 803 so that the pressing cylinder 803 corresponds to the pressing position of the air-conditioning chassis, and then the positioning rod 805 is inserted into the positioning groove 804 to fix the position of the pressing cylinder 803, and then the above-mentioned processing process is performed.

Those skilled in the art should understand that the utility model is not limited by the above embodiments.
