Description

Technical Field

[0001] The present application relates to the technical field of welding equipment, and in particular to a compressor welding device. Background Art

[0002] A compressor is a fluid machine that boosts low-pressure gas to high-pressure gas, and is the heart of the refrigeration system. Common compressor types include piston, screw, scroll, and centrifugal compressors. As the heart of the refrigeration system, the compressor primarily transports the medium, a process that relies on pipelines. Pipeline installation is a critical step in compressor production. First, pipes of appropriate materials and specifications must be precisely selected according to design requirements. Then, they are connected one by one through a rigorous welding process. The quality of welding directly impacts the performance and safety of the entire compressor. Leaks in the pipes during operation can not only affect cooling efficiency but can also lead to serious safety accidents. Only after the pipes are welded can they be accurately installed on the compressor, ensuring the tightness and reliability of the entire system. This ensures that the compressor can properly perform its critical role as the heart of the refrigeration system, providing stable and efficient power support for various cooling needs.

[0003] For example, the Chinese patent document with publication number CN116727953B discloses a welding device for air compressor pipes, including a frame, on which are respectively provided: a clamping assembly, which includes a movable ring and a plurality of clamping claws; a fixed seat and a movable seat, both of which are movably provided with a clamping assembly; the first connecting rod includes the following two states: the first connecting rod is coupled with the two clamping assemblies, and the two clamping assemblies rotate synchronously; the first connecting rod is decoupled from any clamping assembly, and the two clamping assemblies can rotate relative to each other; the first and second gears are respectively provided at both ends of the first connecting rod, and the two movable rings are provided with gear rings, the fixed seat is internally provided with a third gear that is meshed with the first gear and the gear ring, the movable seat is internally provided with a fourth gear that is meshed with the second gear and the gear ring, and the fourth gear is provided with a screw. During welding, the ends of the two pipes are respectively inserted into the two clamping assemblies, and the clamping jaws are driven to move. The clamping jaws clamp the ends of the two pipes, and the movable seat drives the pipes to move so that the end faces of the two pipes are pressed against each other. At this time, the welding robot can be used to weld the joints of the two pipes.

[0004] In the above-mentioned related technologies, when welding the compressor pipe, the two horizontal pipes can be fixed by two clamping assemblies and a movable seat, and then the welding robot welds the joints. However, when welding the three-way pipe, an additional special welding equipment is required for welding. When welding the three-way pipe with special equipment, one pipe needs to be set vertically and one pipe needs to be set horizontally. Then, the horizontal and vertical pipes are manually adjusted. After the position adjustment is completed, the vertically set pipe is fixed to the horizontal pipe by spot welding, and the horizontal pipe is clamped and fixed by the clamping assembly. Finally, the welding is performed by the welding robot, which will cause the efficiency of welding the three-way pipe to decrease during the welding process. Summary of the Invention

[0005] The present application provides a compressor welding device, which aims to solve the problem of low efficiency in welding compressor tee pipes in related technologies.

[0006] The present application provides a compressor welding device that adopts the following technical solution:

The repairing kit for automotive dents, according to claim 1, wherein a bottom of the foot stand comprises a through-hole, and the two foot pieces comprise two bosses, wherein the bosses comprise a through-hole, a screw bolt, and a nut. The through-hole, the bosses comprise a through-hole, a screw bolt, and a nut. The through-hole comprises a first end, a second end, and a second end. The bosses comprise a first end, a second end, and a second end.

[0008] The invention relates to a novel method for welding two compressor pipes in a horizontal direction, wherein the first clamping assembly fixes one pipe, the second clamping assembly fixes the other pipe, the adjusting screw rotates, and the first mounting plate moves, which causes the first clamping assembly to move the pipe closer to the other pipe, and finally the ends of the two pipes abut. The welding robot then performs welding, thereby achieving the purpose of welding horizontal pipes. When welding a compressor tee pipe, the vertical pipe and the horizontal pipe are both placed horizontally, and the first clamping assembly clamps and fixes the horizontal pipe, and the second clamping assembly fixes the vertical pipe. The lifting assembly then drives the second clamping assembly and the vertical pipe upward. During the movement, the vertical pipe, the second clamping assembly, and the abutting assembly rotate to a vertical state under the action of gravity. The abutting assembly pushes the vertical pipe to abut the horizontal pipe. The first mounting assembly then moves, driving the first clamping assembly and the horizontal pipe to move so that the opening of the horizontal pipe aligns with the opening of the vertical pipe. The welding robot then performs welding. When welding a tee pipe, the position positioning by spot welding is not required, making welding more convenient and quick.

[0009] Optionally, the abutment assembly includes a sliding rod fixed to the second mounting plate and an abutment spring fixed to the second mounting plate, the end of the abutment spring away from the second mounting plate is fixed to the rotating frame, and the rotating frame is provided with a fixing assembly for fixing the position of the sliding rod. When the second clamping assembly is in a vertical state, the fixing assembly fixes the position of the sliding rod, the abutment spring is in a compressed state, and the frame is provided with a pushing assembly for pushing the fixing assembly away from the sliding rod.

[0010] By adopting the above technical solution, when the second clamping assembly is in a vertical state, the fixing assembly fixes the position of the sliding rod, and the abutment spring is in a compressed state. When the second clamping assembly and the vertical pipe are rotated to a vertical state under the action of gravity, the fixing assembly and the sliding rod are disengaged, thereby facilitating the abutment spring to push the second mounting plate to move, and then the sliding rod slides on the rotating frame to make the vertical pipe abut against the horizontal pipe, and then welding is performed by a welding robot. After the welding is completed, the second clamping assembly and the vertical pipe are separated, and the sliding rod is pushed in the opposite direction, and then the position of the sliding rod is continued to be fixed by the fixing assembly, thereby facilitating the installation and fixation of subsequent vertical pipes.

[0011] Optionally, the pushing assembly includes a pushing block on a sliding connection to the frame and a pushing spring fixed to the pushing block, wherein one end of the pushing spring away from the pushing block is fixed to the frame, and the pushing spring pushes the pushing block to move in a direction close to the sliding rod, and when the fixed slot and the pushing block correspond, the pushing spring drives the pushing block to move, and then pushes the fixed block out of the fixed slot; the elastic force of the pushing spring is greater than the elastic force of the fixed spring, and a give way slot is provided on the sliding rod, the width of the give way slot is the same as the width of the pushing block and is smaller than the width of the fixed block, the give way slot and the fixed slot are connected, and when the fixed block is out of the fixed slot, the sliding rod slides on the rotating frame.

[0012] By adopting the above technical solution, the rotating shaft is set to a hollow structure, which is convenient for the pushing block to slide along the axial direction of the rotating shaft; a giveway groove is opened on the sliding rod, the width of the giveway groove is the same as the width of the pushing block, and is smaller than the width of the fixed block, and the giveway groove and the fixed groove are connected. Since the width of the giveway groove is smaller than the width of the fixed block, when the fixed block is in the fixed groove, the fixed block will not move into the giveway groove. When the pushing block moves into the fixed groove, since the width of the giveway groove is the same as the width of the pushing block, when the abutment spring pushes the second clamping assembly to move, the pushing block moves from the fixed groove to the giveway groove, and then the vertical pipe is convenient to abut against the surface of the cross bar.

[0013] Optionally, a pushing surface is provided on the moving rod, and a horizontal cross-section of the pushing surface gradually increases in a direction approaching the ground.

[0014] By adopting the above technical solution, when the moving rod moves upward, the pushing surface will push the pushing block to move away from the moving rod, and then gradually compress the pushing spring, and finally facilitate pushing the fixed block out of the fixing groove.

[0015] Optionally, the rack is provided with a connecting assembly for fixing the second mounting plate to the rack; the connecting assembly includes a mounting block fixed to the rack, a connecting block fixed to the second mounting plate, and a connecting groove provided on the mounting block.

[0016] By adopting the above technical solution, when the second clamping assembly is set horizontally, the connecting block is in the connecting groove, thereby improving the stability of the second clamping assembly. When the second clamping assembly is set vertically, the connecting block is separated from the connecting groove.

[0017] Optionally, the lifting assembly includes a lifting screw slidably connected to the frame and a guide rod slidably connected to the frame, one end of the guide rod is fixed to the moving rod, one end of the lifting screw is also fixed to the moving rod, and a driving assembly for driving the lifting screw to move is provided on the frame.

[0018] By adopting the above technical solution, the driving component drives the lifting screw to move, thereby driving the vertical pipe to move more conveniently.

[0019] Optionally, the driving assembly includes a driving motor fixed on the frame, a driving gear fixed on the output shaft of the driving motor, and a driven gear rotatably connected to the frame, the driving gear and the driven gear are meshed, and the driven gear is passed through the lifting screw and is threadedly connected to the lifting screw.

[0020] By adopting the above technical solution, the driving motor rotates, which can drive the driving gear and the driven gear to rotate, and then drive the lifting screw and the moving rod to slide on the frame, thereby driving the second clamping assembly to move up and down in the vertical direction, and then adjust the position of the vertical pipe.

[0021] Optionally, a proofreading assembly for proofreading the opening on the vertical pipe is provided on the frame; the proofreading assembly includes a proofreading frame fixed on the frame, a limit block slidably connected to the proofreading frame, a proofreading roller rotatably connected to the limit block, and a proofreading spring for pulling the proofreading roller to abut against the surface of the pipe, one end of the proofreading spring is fixed to the proofreading roller, and the other end is fixed to the limit block.

[0022] By adopting the above technical solution, during the welding process of the tee pipe, the vertical pipe will move upward, then the horizontal pipe will move in the direction of entering the vertical pipe, and then the proofreading roller will move to the opening of the horizontal pipe. When the opening of the horizontal pipe is not facing upward, the proofreading roller will be pulled downward under the action of the proofreading spring, and then the proofreading roller will correct the opening on the horizontal pipe, so that the opening on the horizontal pipe and the opening on the vertical pipe can correspond to each other, which is convenient for subsequent welding.

[0023] Optionally, the first mounting assembly includes a first mounting plate slidably connected to the frame, a first mounting ring rotatably connected to the first mounting plate, and a first mounting rod fixed to the first mounting ring. The first clamping assembly is arranged on the first mounting rod, and an adjusting screw is rotatably connected to the frame, and the adjusting screw is threadedly connected to the first mounting plate.

[0024] By adopting the above technical solution, when moving the pipe fixed by the first clamping assembly, the adjusting screw is directly rotated, and the adjusting screw mobilizes the first installation assembly and the first clamping assembly to move, thereby achieving the purpose of facilitating the adjustment of the horizontal pipe position.

[0025] Optionally, the first clamping assembly includes a bidirectional screw rotatably connected to the first mounting rod, a first movable block and a second movable block slidably connected to the first mounting rod, the first movable block and the second movable block are hingedly connected on the same side of the first movable block and the second movable block, and the first clamping block is hingedly connected to one end of the connecting rod away from the first movable block and the second movable block, and the first movable block and the second movable block are hingedly connected. Two connecting rods are respectively hinged on the first movable block and the second movable block, and the two connecting rods are arranged on opposite sides of the first movable block, and first clamping blocks for being hinged to the connecting rod are provided on both sides of the first movable block, and the bidirectional screw is passed through the first movable block and the second movable block, and is threadedly connected to the first movable block and the second movable block.

[0026] By adopting the above technical solution, the bidirectional screw is rotated to drive the first moving block and the second moving block to move in opposite directions, and then the two first clamping blocks are abutted against the inner wall of the pipe, thereby fixing the pipe.

[0041] The following combination Figures 1-9 This application is described in further detail.

[0042] The embodiment of the present application discloses a compressor welding device. Figure 1 and Figure 2A compressor welding device includes a frame 01 and a welding robot 02 arranged on the frame 01, and a first clamping assembly 8, a second clamping assembly 06 and a proofreading assembly 1 are arranged on the frame 01. The first clamping assembly 8 and the second clamping assembly 06 are used to fix the pipeline, and the proofreading assembly 1 is used to proofread the position of the pipeline; a lifting assembly 2, a rotating assembly 3 and an abutment assembly 4 are arranged on the frame 01, and the rotating assembly 3 is installed on the lifting assembly 2. The lifting assembly 2 is used to drive the rotating assembly 3 to move up and down in the vertical direction, and the rotating assembly 3 is used to drive the horizontal pipeline to rotate to a vertical state, which is then convenient for welding by the welding robot 02. The abutment assembly 4 is used to connect the rotating assembly 3 and the second clamping assembly 06, and the abutment assembly 4 is also used to push the second clamping assembly 06 in the vertical state to move to a position close to the horizontal pipe. In addition, when welding the pipe, the pipe is manually fixed on the first clamping component 8 and the second clamping component 06, and then the fixed transverse pipe opening cannot be guaranteed to face upward. The fixed transverse pipe opening will appear tilted forward or backward, and then the fixed transverse pipe opening is calibrated by the calibration component 1.

[0043] Reference Figures 2 to 5 A fixing component 5 is provided on the rotating component 3, and the fixing component 5 is used to fix the position of the abutting component 4. At the same time, a pushing component 6 is provided on the frame 01, and the pushing component 6 is used to drive the fixing component 5 to move, so that the fixing component 5 and the abutting component 4 are disengaged, and then the abutting component 4 pushes the second clamping component 06 and the vertical pipe fixed on the second clamping component 06 to abut on the horizontal pipe, and at the same time facilitates subsequent welding by the welding robot 02.

[0044] Reference Figures 2 to 4 A first mounting assembly 7 for mounting a first clamping assembly 8 is provided on the frame 01. The first mounting assembly 7 includes a first mounting plate 71 slidably connected to the frame 01, a first mounting ring 72 rotatably connected to the first mounting plate 71, and a first mounting rod 73 fixed to the first mounting ring 72. In order to facilitate the adjustment of the position of the first clamping assembly 8, an adjusting screw 03 is rotatably connected to the frame 01. The adjusting screw 03 is threadedly connected to the first mounting plate 71, thereby driving the first clamping assembly 8 to reciprocate along the width direction of the frame 01. The adjusting screw 03 can be connected to a servo motor, and the adjusting screw 03 is driven to rotate by the servo motor, thereby facilitating the adjustment of the position of the first clamping assembly 8.

[0045] Reference Figures 2 to 4The first clamping assembly 8 includes a bidirectional screw 81 rotatably connected to the first mounting rod 73, a first moving block 82 and a second moving block 83 slidably connected to the first mounting rod 73, and a connecting rod 84 is hinged on the same side of the first moving block 82 and the second moving block 83, and the connecting rod 84 is hinged on one end of the first moving block 82 and the second moving block 83, and two connecting rods 84 are hinged on the first moving block 82 and the second moving block 83, respectively. The two connecting rods 84 are arranged on the opposite sides of the first moving block 82, and both sides of the first moving block 82 are provided with a first clamping block 85 for being hinged to the connecting rod 84. The bidirectional screw 81 is penetrated by the first moving block 82 and the second moving block 83, and is threadedly connected to the first moving block 82 and the second moving block 83. By rotating the bidirectional screw 81, the first moving block 82 and the second moving block 83 are driven to move in opposite directions, and then the two first clamping blocks 85 are abutted against the inner wall of the pipe, thereby achieving the fixation of the pipe.

[0046] Reference Figures 2 to 4 A second mounting assembly 9 is provided on the second clamping assembly 06, and the second mounting assembly 9 includes a second mounting plate 91 slidably connected to the frame 01, a second mounting ring 92 rotatably connected to the second mounting plate 91, and a second mounting rod 93 fixed to the second mounting ring 92; since the structure of the second clamping assembly 06 is the same as that of the first clamping assembly 8, the specific structure and working principle of the second clamping assembly 06 will not be described in detail here.

[0047] Reference Figures 2 to 4 The rotating assembly 3 includes a moving rod 31 slidably connected to the frame 01 along the vertical direction, a rotating frame 32 fixed on the second mounting plate 91, and a rotating shaft 33 fixed on the rotating frame 32. The rotating shaft 33 is rotatably connected to the moving rod 31, and the rotating shaft 33 is fixed on the moving rod 31 through the fixing assembly 5. The abutment assembly 4 is used to connect the second mounting plate 91 and the rotating frame 32; when welding the compressor tee pipeline, the vertical pipe and the horizontal pipe are placed horizontally, and then the horizontal pipe is clamped and fixed by the first clamping assembly 8, and the vertical pipe is fixed by the second clamping assembly 06. Then, the second clamping assembly 06 and the vertical pipe are driven upward by the lifting assembly 2. During the movement, the vertical pipe, the second clamping assembly 06 and the abutment assembly 4 will rotate to a vertical state under the action of gravity. At the same time, the pushing assembly 6 will disengage the fixing assembly 5 and the abutment assembly 4, and then the abutment assembly 4 pushes the vertical pipe to abut on the horizontal pipe.

[0048] Reference Figures 2 to 4When the second clamping assembly 06 is in the vertical state, the fixing assembly 5 fixes the position of the sliding rod 41, and the abutment spring 42 is in a compressed state. When the second clamping assembly 06 and the vertical pipe are rotated to the vertical state under the action of gravity, the fixing assembly 5 and the sliding rod 41 are disengaged, thereby facilitating the abutment spring 42 to push the second mounting plate 91 to move, and then the sliding rod 41 slides on the rotating frame 32, so that the vertical pipe abuts against the horizontal pipe, and then the welding robot 02 is used for welding. After the welding is completed, the second clamping assembly 06 and the vertical pipe are separated, pushing the sliding rod 41 in the opposite direction, and then the position of the sliding rod 41 is continued to be fixed by the fixing assembly 5, thereby facilitating the installation and fixing of subsequent vertical pipes.

[0049] Reference Figures 4 to 6 The fixing assembly 5 includes a fixing block 51 slidably connected to the rotating frame 32, a fixing spring 52 fixed to the fixing block 51, and a fixing slot 53 defined in the sliding rod 41. The fixing slot 53 and the fixing block 51 have the same cross-section. The end of the fixing spring 52, away from the fixing block 51, is fixed to the rotating frame 32. The fixing spring 52 is used to push the fixing block 51 into the fixing slot 53, thereby fixing the position of the sliding rod 41 and keeping the abutment spring 42 in a compressed state. In this embodiment, the fixing block 51 is configured as a hexagonal prism structure.

[0050] Reference Figures 4 to 7The pushing assembly 6 includes a pushing block 61 slidably connected to the frame 01 and a pushing spring 62 fixed to the pushing block 61. The end of the pushing spring 62 away from the pushing block 61 is fixed to the frame 01. The pushing spring 62 pushes the pushing block 61 to move in the direction close to the sliding rod 41. When the fixed groove 53 and the pushing block 61 correspond, the pushing spring 62 drives the pushing block 61 to move, and then pushes the fixed block 51 out of the fixed groove 53. In order to facilitate the pushing block 61 to push the fixed block 51 out of the fixed groove 53, the vertical cross-section of the pushing block 61 is smaller than the cross-section of the fixed block 51, and the elastic force of the pushing spring 62 is greater than the elastic force of the fixed spring 52. In addition, the rotating shaft 33 is set to a hollow structure to facilitate the pushing block 61 to slide along the axial direction of the rotating shaft 33; a clearance groove 04 is provided on the sliding rod 41. The width of the clearance groove 04 is the same as the width of the pushing block 61 and is smaller than the width of the fixed block 51. The clearance groove 04 and the fixed groove 53 is connected. Since the width of the give way groove 04 is smaller than the width of the fixed block 51, when the fixed block 51 is in the fixed groove 53, the fixed block 51 will not move into the give way groove 04. When the pushing block 61 moves into the fixed groove 53, since the width of the give way groove 04 is the same as the width of the pushing block 61, when the abutment spring 42 pushes the second clamping assembly 06 to move, the sliding rod 41 moves, and the pushing block 61 moves from the fixed groove 53 into the give way groove 04, and then the vertical pipe is facilitated to abut against the surface of the cross bar.

[0051] When the fixed groove 53 and the pushing block 61 correspond to each other, the pushing spring 62 pushes the pushing block 61 to pass through the hollow rotating shaft 33 and move into the fixed groove 53. When the pushing block 61 moves into the fixed groove 53, it will push the fixed block 51 out of the fixed groove 53, and then the fixed block 51 no longer fixes the sliding rod 41. Since the vertical cross-section of the pushing block 61 is smaller than the cross-section of the fixed block 51, and the elastic force of the pushing spring 62 is greater than the elastic force of the fixing spring 52, the sliding rod 41 will be pushed to slide in the vertical direction on the rotating frame 32 under the action of the abutment spring 42, and finally the vertical pipe is pushed to abut against the surface of the horizontal pipe.

[0052] Reference Figures 4 to 6 A pushing surface 05 is provided on the moving rod 31. The horizontal cross-section of the pushing surface 05 gradually increases along the surface close to the ground. In the process of the lifting assembly 2 driving the moving rod 31 to move upward, the pushing surface 05 will push the pushing block 61 to move in the direction away from the moving rod 31, and then the pushing spring 62 will be gradually compressed. When the fixed groove 53 and the pushing block 61 correspond, the vertical pipe moves to the top, and the vertical pipe rotates to a vertical state under the action of gravity. At this time, the pushing spring 62 drives the pushing block 61 to move. In the process of the pushing block 61 moving, the fixed block 51 is pushed out of the fixed groove 53, and then the abutment spring 42 pushes the vertical pipe to abut against the horizontal pipe.

[0053] Reference Figures 2 to 4A connecting assembly 10 is provided on the frame 01. This connecting assembly 10 is used to secure the second mounting plate 91 to the frame 01. The connecting assembly 10 includes a mounting block 101 secured to the frame 01, a connecting block 102 secured to the second mounting plate 91, and a connecting slot 103 defined in the mounting block 101. When the second clamping assembly 06 is positioned horizontally, the connecting block 102 is positioned within the connecting slot 103, thereby enhancing the stability of the second clamping assembly 06. When the second clamping assembly 06 is positioned vertically, the connecting block 102 is disengaged from the connecting slot 103. In this embodiment, the connecting block 102 is made of an elastic material and has an abutting surface to facilitate movement of the connecting block 102 into the connecting slot 103.

[0054] Reference Figure 5 and Figure 8 The lifting assembly 2 includes a lifting screw 21 slidably connected to the frame 01 and a guide rod 22 slidably connected to the frame 01. One end of the guide rod 22 is fixed to the moving rod 31, and one end of the lifting screw 21 is also fixed to the moving rod 31. A driving assembly 15 is provided on the frame 01 for driving the lifting screw 21 to move.

[0055] Reference Figure 5 and Figure 8 The driving assembly 15 includes a driving motor 151 fixed on the frame 01, a driving gear 152 fixed on the output shaft of the driving motor 151, and a driven gear 153 rotatably connected to the frame 01. The driving gear 152 and the driven gear 153 are meshed. The driven gear 153 is passed through the lifting screw 21 and is threadedly connected to the lifting screw 21. By rotating the driving motor 151, the driving gear 152 and the driven gear 153 can be driven to rotate, and then the lifting screw 21 and the moving rod 31 are driven to slide on the frame 01, thereby driving the second clamping assembly 06 to move up and down in the vertical direction, and then the position of the vertical pipe is adjusted.

[0056] Reference Figure 1 and Figure 9When there is no need to weld the three-way pipe, the drive motor 151 does not work, so that the first clamping assembly 8 and the second clamping assembly 06 are both set horizontally, and then the first clamping assembly 8 and the second clamping assembly 06 respectively fix a pipe, and the adjusting screw 03 is rotated to drive the first clamping assembly 8 to move, and then the pipe fixed by the first clamping assembly 8 is abutted against the pipe end face fixed by the second clamping assembly 06, and finally welding is performed by the welding robot 02, so that two horizontal pipes can be fixed and welded, and the three-way pipe can also be fixed and welded, thereby improving the utilization rate of the welding equipment; in addition, under the action of the abutting assembly 4 and the rotating assembly 3, the horizontal pipe can be rotated to a vertical state, and then abutted against the pipe surface fixed by the first clamping assembly 8, so that when welding the three-way pipe, there is no need to perform preliminary fixation by spot welding, thereby improving the welding efficiency.

[0057] Reference Figure 1 and Figure 2 The proofreading assembly 1 includes a proofreading frame 11 fixed on the frame 01, a limit block 12 slidably connected to the proofreading frame 11, a proofreading roller 13 rotatably connected to the limit block 12, and a proofreading spring 14 for pulling the proofreading roller 13 against the surface of the pipe. One end of the proofreading spring 14 is fixed on the proofreading roller 13, and the other end is fixed on the limit block 12. During the welding of the tee pipe, the vertical pipe will move upward, and then the horizontal pipe will move in the direction of entering the vertical pipe, and then the proofreading roller 13 will move to the opening of the horizontal pipe. When the opening of the horizontal pipe is not facing upward, the proofreading roller 13 will be pulled downward under the action of the proofreading spring 14, and then the proofreading roller 13 will correct the opening on the horizontal pipe, so that the opening on the horizontal pipe can correspond to the opening on the vertical pipe, which is convenient for subsequent welding. Since the abutment spring 42 pushes the vertical tube to abut against the cross tube, when the opening on the cross tube does not correspond to the opening on the vertical tube, the movement of the cross tube can adjust the position of the vertical tube so that the two tips of the vertical tube are in the front and back positions, thereby achieving the purpose of automatically adjusting the positions of the cross tube and the vertical tube.

[0058] During manual installation, the cross tube opening may be tilted. There are two states of cross tube tilting. One state is: the lowest point in front of the cross tube is higher than the lowest point behind the cross tube, and the other state is: the lowest point in front of the cross tube is lower than the lowest point behind the cross tube. When installing the cross tube, it is also necessary to move the correction roller 13 upward so that the correction roller 13 moves to the top of the cross tube, and then release the correction roller 13. The correction roller 13 abuts against the surface of the cross tube under the action of the correction spring 14. In the process of horizontal movement of the cross tube, the correction roller 13 has a force to move downward. Then, when the correction roller 13 moves to the cross tube opening, when the lowest point in front of the cross tube is higher than the lowest point behind the cross tube, the lowest point in front of the cross tube will first contact the correction roller 13, and then the correction spring 14 pulls the correction roller 13 downward. At this time, the correction roller 13 will press the cross tube to rotate, so that the lowest point in front and the lowest point at the rear of the cross tube will abut against the correction roller 13. At this time, the opening on the cross tube is facing upward. When the lowest point in front of the transverse tube is lower than the lowest point behind the transverse tube, the lowest point in front of the transverse tube will first contact the proofreading roller 13, and then the proofreading spring 14 will pull the proofreading roller 13 downward. At this time, the proofreading roller 13 will press the transverse tube to rotate, so that the lowest point in front and the lowest point behind the transverse tube will both abut against the proofreading roller 13. At this time, the opening on the transverse tube is facing upwards, thereby achieving the purpose of proofreading the transverse tube opening.

[0059] In addition, when the tip of the vertical tube is not facing forward, the opening of the vertical tube cannot completely abut against the surface of the horizontal tube. Under the action of the abutment spring 42, an edge of the vertical tube opening will abut against the surface of the horizontal tube, and will push the vertical tube to rotate during the horizontal movement of the horizontal tube. At the same time, the abutment spring 42 will also push the vertical tube to move slowly downward, and then the tip of the vertical tube will be directly in front, thereby realizing the correction of the position of the vertical tube opening.

[0060] The implementation principle of a compressor welding device in an embodiment of the present application is: when welding two horizontal compressor pipes, one pipe is fixed by the first clamping assembly 8, and then the second clamping assembly 06 fixes the other pipe, and the adjusting screw 03 rotates to drive the first mounting plate 71 to move. At this time, the first clamping assembly 8 will drive the pipe to move closer to the other pipe, and finally the ends of the two pipes are abutted, and then welding is performed by the welding robot 02 to achieve the purpose of welding horizontal pipes.

[0061] When welding a three-way pipe, the worker fixes the position of the horizontal pipe through the first clamping assembly 8, and then fixes the position of the vertical pipe through the second clamping assembly 06. The lifting assembly 2 drives the moving rod 31, the rotating assembly 3 and the second clamping assembly 06 to move upward. At the same time, the adjusting screw 03 also drives the first clamping assembly 8 and the pipe fixed on the first clamping assembly 8 to move toward the second clamping assembly 06. In the process of the rotating assembly 3 moving upward, under the action of gravity, the second clamping assembly 06, the abutting assembly 4 and the vertical pipe will rotate around the rotating shaft 33, and the pushing surface 05 will cause the pushing block 61 to move toward the sliding rod 41. After the vertical pipe rotates to a vertical state, the lifting assembly 2 drives the moving rod 31, the rotating assembly 3 and the second clamping assembly 06 to move upward. Component 2 drives the vertical pipe in the vertical state to continue to move upward until the fixed groove 53 and the pushing block 61 correspond. The pushing block 61 pushes the fixed block 51 out of the fixed groove 53, and then the sliding rod 41 will move in the vertical direction on the rotating frame. The abutment spring 42 pushes the vertical pipe to abut the horizontal pipe. The horizontal pipe continues to move, and the proofreading roller 13 proofreads the opening of the horizontal pipe. When the vertical pipe is tilted, the opening of the vertical pipe can be proofread during the movement of the horizontal pipe. Finally, the opening of the horizontal pipe and the opening of the vertical pipe are made to correspond, and welding is performed by the welding robot 02 to achieve the purpose of welding three-way pipes without spot welding, thereby improving work efficiency. In addition, this equipment can also weld two horizontally arranged pipes to improve the utilization rate of welding equipment.
