Description

Technical Field

[0001] The invention relates to the technical field of welding equipment, in particular to a welding device used for processing automobile air-conditioning pipes. Background Art

[0002] Automobile air conditioning pipes are an important part of the automobile air conditioning system. They are mainly responsible for the transmission of refrigerant to ensure the normal operation of the air conditioning system. Automobile air conditioning pipes can be mainly divided into two types: high-pressure pipes and low-pressure pipes. High-pressure pipes, also known as liquid pipes, usually have a liquid refrigerant flowing in them at a higher pressure. They are responsible for transporting the high-temperature and high-pressure liquid refrigerant output from the compressor to the condenser for heat dissipation, and then the refrigerant becomes a medium-temperature and high-pressure liquid or a gas-liquid mixed state in the condenser. Low-pressure pipes, also known as gas pipes, usually have a gaseous refrigerant flowing in them at a lower pressure. They are responsible for transporting the low-temperature and low-pressure gaseous refrigerant flowing out of the evaporator to the compressor for compression in preparation for the next refrigeration cycle.

[0003] The functions of automobile air conditioning pipes are mainly reflected in the following aspects: Transmitting refrigerant: They are the channels for the refrigerant to circulate in the automobile air conditioning system, ensuring that the refrigerant can circulate according to the predetermined path, thereby achieving the cooling effect of the air conditioning system. Isolation and protection: Automobile air conditioning pipes also play the role of isolating and protecting the refrigerant, preventing it from direct contact with the external environment, and avoiding refrigerant leakage or contamination. Adjusting temperature and humidity: Through the transmission of air conditioning pipes, the refrigerant can absorb heat in the evaporator, reduce the temperature and humidity in the car, and provide a comfortable riding environment. Filtering and purification: Some automobile air conditioning pipes are also equipped with filtering devices to filter and purify impurities and moisture in the refrigerant to ensure the normal operation and cooling effect of the air conditioning system. In general, automobile air conditioning pipes are an indispensable part of the automobile air conditioning system, and their functions and performance directly affect the cooling effect of the air conditioning system and the comfort of passengers.

[0004] However, in actual use of the existing technology, the pipes in the automobile air-conditioning system play a key role in transporting refrigerant, and their processing quality directly affects the air-conditioning performance. In the production process of automobile air-conditioning pipes, welding is an important process. Most of the current welding devices are difficult to effectively and conveniently fix automobile air-conditioning pipes of different shapes and diameters, resulting in easy displacement of the pipes during welding, affecting the welding accuracy and reducing the product qualification rate. At the same time, it also consumes a lot of manpower to adjust the position of the pipes, reducing production efficiency. Summary of the invention

[0020] When in use, the air-conditioning pipe to be welded is placed on the inner side of the clamping block 222. When the air-conditioning pipe is placed on the inner side of the clamping block 222, the clamping electric telescopic rod 218 is opened and extended through synchronous control. When the clamping electric telescopic rod 218 is opened and extended through synchronous control, the telescopic slot 219 is driven to move inward in a synchronous straight line. When the telescopic slot 219 moves inward in a synchronous straight line, the clamping block 222 is driven to move inward in a straight line. When the clamping block 222 moves inward in a straight line, the air-conditioning pipe is clamped and fixed. When the clamping block 222 clamps and fixes the air-conditioning pipe, the buffer spring 221 cooperates with the telescopic slot 219 to perform elastic buffering and limiting on the clamping block 222, so that the clamping block 222 can avoid squeezing of the air-conditioning pipe when clamping and fixing the air-conditioning pipe.

When the welding gun head 316 moves linearly downward, the welding gun head 316 is close to the welding point of the clamped and fixed air-conditioning pipe. When the welding gun head 316 is close to the welding point of the clamped and fixed air-conditioning pipe, the air-conditioning pipe can be welded by controlling the opening of the welding gun head 316, thereby facilitating the fixing, clamping and welding of the air-conditioning pipe. By controlling to turn on the fifth drive motor 309, when the fifth drive motor 309 is turned on, it will drive the fourth transmission gear 310 to rotate. When the fourth transmission gear 310 rotates, the force generated by the meshing connection between the fourth transmission gear 310 and the transmission spur rack 311 will synchronously drive the moving platform 308 to move forward and backward.

When the second transmission gear plate 303 rotates, it will drive the swing shaft column 304 to rotate. When the swing shaft column 304 rotates, it will drive the swing support frame 3 to swing and adjust significantly. When the swing support frame 3 swings and adjusts significantly, it will synchronously drive the welding gun head 316 to swing left and right to adjust the welding position of the air-conditioning pipe, thereby achieving fixed clamping and welding of the air-conditioning pipe while facilitating front and rear linear movement and left and right swing adjustment of the welding position of the air-conditioning pipe; At the same time, when the swing support frame 3 is swung and adjusted to the inner side of the infrared transmitting sensor 318 and the infrared receiving sensor 319, the infrared signals of the infrared transmitting sensor 318 and the infrared receiving sensor 319 will be blocked and disconnected by the swing support frame 3. When the infrared signals of the infrared transmitting sensor 318 and the infrared receiving sensor 319 are disconnected, the swing support frame 3 can be controlled to stop swinging in turn, so that the swing support frame 3 is limited to the extreme swing position through the infrared transmitting sensor 318 and the infrared receiving sensor 319, so as to avoid the swing support frame 3 from swinging too much and causing collision damage. By controlling to turn on the first drive motor 204, when the first drive motor 204 is turned on, it will drive the first transmission gear 205 to rotate. When the first transmission gear 205 rotates, it will mesh and drive the first transmission gear plate 203 to rotate. When the first transmission gear plate 203 rotates, it will drive the U-shaped support platform 202 to swing slightly left and right. When the U-shaped support platform 202 swings slightly left and right, it will synchronously drive the clamped and fixed air-conditioning pipe to swing slightly left and right to adjust the welding position, so as to further improve the flexibility of the welding position of the air-conditioning pipe; At the same time, before the air-conditioning pipe is clamped and fixed, the second drive motor 209 is controlled to be turned on. When the second drive motor 209 is turned on, the first synchronous wheel 210 is driven to rotate. When the first synchronous wheel 210 rotates, the second synchronous wheel 211 is driven to rotate through the synchronous belt transmission. When the second synchronous wheel 211 rotates, the adjusting screw rod 207 is driven to rotate, and the outer curved threads at both ends of the adjusting screw rod 207 are in opposite directions, so that when the adjusting screw rod 207 rotates, the horizontal slider 208 is driven to move outward or inward in a straight line synchronously due to the force generated by the screw rod nut transmission connection. When the horizontal slider 208 moves outward or inward in a straight line synchronously, it will synchronously drive the clamping block 222 to move outward or inward in a straight line to adjust the clamping position of the clamping pipe. The first electric telescopic rod 212 is controlled to be turned on. When the first electric telescopic rod 212 is turned on, it will drive the first lifting plate 213 to move up and down in a straight line. When the first lifting plate 213 moves in a straight line, it will synchronously drive the clamping block 222 to move up and down in a straight line to adjust the clamping position of the clamping tube. The third driving motor 223 is turned on by control. When the third driving motor 223 is turned on, it will drive the second transmission gear 224 to rotate. When the second transmission gear 224 rotates, it will engage and drive the transmission gear ring 225 to rotate. When the transmission gear ring 225 rotates, it will drive the rotating shaft column 215 to rotate. When the rotating shaft column 215 rotates, it will drive the horizontal rotating table 216 to rotate. When the horizontal rotating table 216 rotates, it will synchronously drive the clamping block 222 to rotate horizontally to adjust the clamping position of the clamping tube, thereby achieving fixed clamping and welding of the air-conditioning tube, while facilitating the adjustment of the clamping position of the air-conditioning tube up and down, front and back, and horizontal rotation, so as to improve the flexibility of the clamping block 222 in clamping air-conditioning tubes of different shapes and diameters.
