Description

Technical Field

[0001] This invention relates to the field of welding equipment technology, specifically a welding device for processing automotive air conditioning pipes. Background Technology

[0002] Automotive air conditioning pipes are an important component of the automotive air conditioning system. They are primarily responsible for the transport of refrigerant, ensuring the normal operation of the system. Automotive 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, typically carry liquid refrigerant at higher pressure. They are responsible for delivering the high-temperature, high-pressure liquid refrigerant from the compressor to the condenser for heat dissipation. The refrigerant then transforms into a medium-temperature, high-pressure liquid or gas-liquid mixture in the condenser. Low-pressure pipes, also known as gas pipes, typically carry gaseous refrigerant at lower pressure. They are responsible for delivering the low-temperature, low-pressure gaseous refrigerant from the evaporator to the compressor for compression, preparing for the next refrigeration cycle.

[0003] The main functions of automotive air conditioning pipes are as follows: Refrigerant transport: They serve as channels for the refrigerant to circulate within the automotive air conditioning system, ensuring it follows a predetermined path to achieve the desired cooling effect. Isolation and protection: Automotive air conditioning pipes also isolate and protect the refrigerant, preventing direct contact with the external environment and avoiding leaks or contamination. Temperature and humidity regulation: Through the air conditioning pipes, the refrigerant absorbs heat in the evaporator, lowering the temperature and humidity inside the vehicle and providing a comfortable riding environment. Filtration and purification: Some automotive air conditioning pipes are also equipped with filters to remove impurities and moisture from the refrigerant, ensuring the normal operation and cooling effect of the air conditioning system. In summary, automotive air conditioning pipes are an indispensable component of the automotive air conditioning system; their function and performance directly affect the cooling effect and passenger comfort.

[0004] However, in practical applications, the pipes in automotive air conditioning systems play a crucial role in transporting refrigerant, and their processing quality directly affects air conditioning performance. Welding is a critical step in the production of automotive air conditioning pipes. Current welding equipment often struggles to effectively and conveniently fix automotive air conditioning pipes of varying shapes and diameters, leading to pipe displacement during welding, affecting welding accuracy, reducing product yield, and consuming significant manpower for pipe repositioning, thus decreasing production efficiency. Summary of the Invention

[0005] The purpose of this invention is to provide a welding device for processing automotive air conditioning pipes, addressing the issues raised in the background section regarding the crucial role of pipes in automotive air conditioning systems, such as transporting refrigerant, and the direct impact of their processing quality on air conditioning performance. In the production of automotive air conditioning pipes, welding is a critical step.

[0010] Preferably, an operation console is fixedly installed on the upper rear side of the mounting base plate, and the operation console is electrically connected to a handheld operator via a wire.

[0011] Preferably, the fixed support frame is fixedly installed on the upper end of the upper mounting base plate, the upper end of the first transmission gear is meshed with the lower end of the first transmission gear disk, and there are two limiting straight slide grooves, which are symmetrically distributed on the front and rear sides of the lower end of the U-shaped support platform.

[0017] Compared with the prior art, the beneficial effects of the present invention are:

[0018] This invention controls the activation of a fifth drive motor. When the fifth drive motor is activated, it sequentially drives the moving platform to move back and forth. When the moving platform moves back and forth, it drives the limiting slide block to move linearly back and forth along the lower end of the limiting slide rail. This allows the limiting slide block and the limiting slide rail to limit the linear movement of the moving platform. When the moving platform moves linearly back and forth, it simultaneously drives the welding gun head to move linearly back and forth to adjust the welding position. At the same time, the invention controls the activation of a fourth drive motor. When the fourth drive motor is activated, it sequentially drives the swing shaft column to rotate. When the swing shaft column rotates, it drives the swing support frame to swing significantly. When the swing support frame swings significantly, it simultaneously drives the welding gun head to swing significantly left and right to adjust the welding position of the air conditioning pipe. This allows for the fixed clamping and welding of the air conditioning pipe while facilitating linear movement back and forth and significant left and right swing adjustment of the welding position of the air conditioning pipe.

[0019] Before clamping and fixing the air conditioning pipe, this invention also allows for the activation of a second drive motor. When the second drive motor is activated, it sequentially drives a horizontal slider to move linearly outward or inward. This linear movement of the horizontal slider, in turn, moves the clamping block outward or inward to adjust the clamping position of the pipe. Furthermore, by activating a first electric telescopic rod, the clamping block moves linearly up and down to adjust the clamping position of the pipe. Finally, by activating a third drive motor, a horizontal rotating platform rotates. This rotation of the platform, in turn, rotates the clamping block horizontally to adjust the clamping position of the pipe. This allows for the simultaneous fixing, clamping, and welding of the air conditioning pipe while facilitating vertical, horizontal, and lateral adjustments to the clamping position, thus improving the flexibility of the clamping block in clamping air conditioning pipes of various shapes and diameters.

[0030] A fourth drive motor 301 is fixedly mounted on the upper center of the mounting base plate 1. The front drive shaft of the fourth drive motor 301 is rotatably connected to the upper end of the mounting base plate 1 via a bearing seat. A third drive gear 302 is fixedly mounted on the front drive shaft of the fourth drive motor 301. A second drive gear 303 is meshed with the upper end of the third drive gear 302. A swing shaft column 304 is fixedly mounted in the middle of the second drive gear 303. The front and rear ends of the swing shaft column 304 are rotatably connected to the lower end of the fixed support frame 2 via a rotating shaft. A swing support frame 3 is fixedly mounted on the front and rear ends of the swing shaft column 304. The upper center of the swing support frame 3 is connected to the swing shaft column 304 via a rotating shaft. An opening slot 305 is provided. Two limiting slide rails 306 are fixedly installed on both sides of the top of the swing support frame 3. These limiting slide rails 306 are symmetrically distributed on both sides of the top of the swing support frame 3. A limiting slide block 307 is movably connected to the lower end of each limiting slide rail 306. A movable platform 308 is fixedly installed at the lower end of the limiting slide block 307. A fifth drive motor 309 is fixedly installed on the side of the movable platform 308. A fourth transmission gear 310 is fixedly installed on the upper drive shaft of the fifth drive motor 309. A transmission rack 311 is meshed with the inner side of the fourth transmission gear 310, and the transmission rack 311 is fixedly installed... Mounted on the upper end of the swing support frame 3, the front and rear ends of the transmission rack 311 are fixedly equipped with limit stops, which limit the front and rear ends of the transmission rack 311. A second electric telescopic rod 312 is fixedly installed through the middle of the lower end of the moving platform 308. A second lifting plate 313 is fixedly installed on the telescopic part of the lower end of the second electric telescopic rod 312. A third limiting slide rod 314 is fixedly installed on the front and rear sides of the upper end of the second lifting plate 313. The upper end of the third limiting slide rod 314 is movably connected to the front and rear sides of the moving platform 308, so that the second lifting plate 313 is linearly limited by the third limiting slide rod 314. A welding support frame 315 is fixedly installed at the lower end of the second lifting plate 313. A welding gun head 316 for welding air conditioning pipes is detachably fixedly installed at the lower end of the welding support frame 315. U-shaped limit frames 317 are fixedly installed on both sides of the front end of the mounting base plate 1. There are two U-shaped limit frames 317, which are symmetrically distributed on both sides of the front end of the mounting base plate 1. An infrared emitting sensor 318 and an infrared receiving sensor 319 for limiting the swing support frame 3 are fixedly installed through the upper end of the U-shaped limit frame 317. The infrared emitting sensor 318 and the infrared receiving sensor 319 are on the same horizontal line.

[0031] In use, the air conditioning pipe to be welded is placed inside the clamping block 222. When the air conditioning pipe is placed inside the clamping block 222, the clamping electric telescopic rod 218 is extended synchronously. When the clamping electric telescopic rod 218 extends synchronously, it drives the telescopic groove 219 to move inward synchronously in a straight line. When the telescopic groove 219 moves inward synchronously in a straight line, it drives the clamping block 222 to move inward synchronously in a straight line. When the clamping block 222 moves inward linearly, it clamps and fixes the air conditioning pipe. When the clamping block 222 clamps and fixes the air conditioning pipe, the buffer spring 221, in conjunction with the telescopic groove 219, provides elastic buffering and limiting for the clamping block 222, so that the clamping block 222 avoids squeezing the air conditioning pipe when clamping and fixing it. In the event of pressure damage, when the air conditioning pipe is clamped and fixed, the second electric telescopic rod 312 is extended downward by control. When the second electric telescopic rod 312 extends downward, it will drive the second lifting plate 313 to move downward in a straight line. When the second lifting plate 313 moves downward in a straight line, it will drive the welding support frame 315 to move downward in a straight line. When the welding support frame 315 moves downward in a straight line, it will drive the welding gun head 316 to move downward in a straight line. When the welding gun head 316 moves downward in a straight line, it will approach the welding point of the clamped and fixed air conditioning pipe. When the welding gun head 316 approaches 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 realizing the function of facilitating the fixing, clamping and welding of the air conditioning pipe.

[0032] By controlling the activation of the fifth drive motor 309, the fifth drive motor 309 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 table 308 to move back and forth. When the moving table 308 moves back and forth, it will drive the limiting slide 307 to move linearly back and forth along the lower end of the limiting slide rail 306. This allows the limiting slide 307 and the limiting slide rail 306 to limit the linear movement of the moving table 308. When the moving table 308 moves linearly back and forth, it will synchronously drive the welding gun head 316 to move linearly back and forth to adjust the welding position. At the same time, by controlling... When the fourth drive motor 301 is turned on, it will drive the third transmission gear 302 to rotate. When the third transmission gear 302 rotates, it will mesh and drive the second transmission gear 303 to rotate. When the second transmission gear 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 significantly. When the swing support frame 3 swings significantly, it will simultaneously drive the welding gun head 316 to swing significantly left and right to adjust the welding position of the air conditioning pipe. This achieves the simultaneous fixed clamping and welding of the air conditioning pipe, and facilitates linear forward and backward movement and significant left and right swing adjustment of the welding position of the air conditioning pipe.

[0033] Meanwhile, when the swing support frame 3 swings significantly to the inside of the infrared emitting sensor 318 and the infrared receiving sensor 319, the infrared signals of the infrared emitting 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 emitting sensor 318 and the infrared receiving sensor 319 are disconnected, the swing support frame 3 can be controlled to stop swinging in sequence. This allows the infrared emitting sensor 318 to work with the infrared receiving sensor 319 to limit the swing of the swing support frame 3, thus avoiding excessive swing adjustment of the swing support frame 3 and causing collision damage.

[0034] By controlling the activation of the first drive motor 204, when the first drive motor 204 is activated, 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 203 to rotate. When the first transmission gear 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 simultaneously drive the clamped and fixed air conditioning pipe to swing slightly left and right to adjust the welding position, thereby further improving the flexibility of the air conditioning pipe welding position.

[0035] Simultaneously, before the air conditioning pipe is clamped and fixed, the second drive motor 209 is activated. When the second drive motor 209 is activated, it drives the first synchronous pulley 210 to rotate. When the first synchronous pulley 210 rotates, it drives the second synchronous pulley 211 to rotate via a synchronous belt drive. When the second synchronous pulley 211 rotates, it drives the adjusting screw 207 to rotate. The two ends of the adjusting screw 207 have opposite external curved thread orientations, so that when the adjusting screw 207 rotates, the force generated by the screw nut transmission connection drives the horizontal slider 208 to move synchronously outward or inward in a straight line. When the horizontal slider 208 moves synchronously outward or inward in a straight line, it synchronously drives the clamping block 222 to move linearly outward or inward to adjust the clamping position of the clamping pipe. The first electric telescopic rod 212 is activated. When the first electric telescopic rod 212 is activated, it drives the first lifting plate 213 to move up and down in a straight line. When the first lifting plate 213 moves vertically, it simultaneously drives the clamping block 222 to move vertically to adjust the clamping position of the clamping tube. By controlling the activation of the third drive motor 223, the third drive motor 223 drives the second transmission gear 224 to rotate. When the second transmission gear 224 rotates, it meshes and drives the transmission gear ring 225 to rotate. When the transmission gear ring 225 rotates, it drives the rotating shaft column 215 to rotate. When the rotating shaft column 215 rotates, it drives the horizontal rotating table 216 to rotate. When the horizontal rotating table 216 rotates, it simultaneously drives the clamping block 222 to rotate horizontally to adjust the clamping position of the clamping tube. This achieves both fixed clamping and welding of the air conditioning tube and facilitates vertical, horizontal, and lateral adjustment of the clamping position of the air conditioning tube, thereby improving the clamping flexibility of the clamping block 222 in clamping air conditioning tubes of different shapes and diameters.
