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] The compressor is a fluid machine that lifts low-pressure gas to high-pressure gas, and is the heart of the refrigeration system. Common compressors include piston compressors, screw compressors, scroll compressors, and centrifugal compressors. As the heart of the refrigeration system, the compressor is mainly used to transport media. In the process of transporting media, pipelines are indispensable. In the production process of the compressor, the installation of pipelines is a key link. First, it is necessary to accurately select pipelines of appropriate materials and specifications according to the design requirements, and then connect the pipelines one by one through a strict welding process. The quality of welding is directly related to the performance and safety of the entire compressor, because once the pipeline leaks during operation, it will not only affect the refrigeration effect, but may also cause serious safety accidents. Only after the pipeline welding is completed can they be accurately installed on the compressor to ensure the sealing and reliability of the entire system, so that the compressor can normally play its key role as the heart of the refrigeration system and provide stable and efficient power support for various refrigeration needs.

[0003] For example, a 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; a first connecting rod including the following two states: the first connecting rod is coupled with 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; a first gear and a second gear are respectively provided at both ends of the first connecting rod, and a gear ring is provided on the two movable rings, a third gear meshing with the first gear and the gear ring is rotatably provided inside the fixed seat, a fourth gear meshing with the second gear and the gear ring is movably provided inside the movable seat, and a screw is provided on the fourth gear. 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 butted together. 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 pipeline, the two horizontal pipelines 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 pipeline, another special welding equipment is required for welding. When the special equipment welds the three-way pipeline, one pipeline needs to be set vertically and the other pipeline needs to be set horizontally. Then, the horizontal and vertical pipelines are manually adjusted. After the position adjustment is completed, the vertically set pipeline is fixed to the horizontal pipeline by spot welding, and the horizontal pipeline 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 pipeline to decrease during the welding process. Summary of the invention

[0012] 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.

[0013] 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 fixed groove.

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 the subsequent welding by the welding robot 02.

[0042] Reference Figures 2 to 4 A first mounting assembly 7 for mounting a first clamping assembly 8 is provided on the frame 01, and 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, and the adjusting screw 03 is threadedly connected to the first mounting plate 71, so that the first clamping assembly 8 can be driven 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, so as to facilitate the adjustment of the position of the first clamping assembly 8.

[0043] 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, a connecting rod 84 is hinged on the same side of the first moving block 82 and the second moving block 83, and a first clamping block 85 is hinged on one end of the connecting rod 84 away from the first moving block 82 and the second moving block 83, two connecting rods 84 are hinged on the first moving block 82 and the second moving block 83, and 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 first clamping blocks 85 for being hinged with the connecting rod 84, the bidirectional screw 81 is penetrated on 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, and the first moving block 82 and the second moving block 83 are driven to move in opposite directions by rotating the bidirectional screw 81, and then the two first clamping blocks 85 are abutted against the inner wall of the pipe, thereby fixing the pipe.

[0044] 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.

[0045] 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 three-way 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 to move 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, and at the same time, the pushing assembly 6 will cause the fixing assembly 5 and the abutment assembly 4 to disengage, and then the abutment assembly 4 pushes the vertical pipe to abut on the horizontal pipe.

[0046] Reference Figures 2 to 4The abutment assembly 4 includes a sliding rod 41 fixed on the second mounting plate 91 and an abutment spring 42 fixed on the second mounting plate 91. The end of the abutment spring 42 away from the second mounting plate 91 is fixed on the rotating frame 32. When the second clamping assembly 06 is in a 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 a 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 welding is performed by the welding robot 02. After welding is completed, the second clamping assembly 06 and the vertical pipe are separated, and the sliding rod 41 is pushed in the opposite direction. 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.

[0047] 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 groove 53 provided on the sliding rod 41. The fixing groove 53 and the fixing block 51 have the same cross section. The fixing spring 52 is fixed to the rotating frame 32 at one end away from the fixing block 51. The fixing spring 52 is used to push the fixing block 51 to move into the fixing groove 53, and then fix the position of the sliding rod 41, so that the abutting spring 42 is in a compressed state. In this embodiment, the fixing block 51 is set as a hexagonal prism structure.

[0048] 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 on the pushing block 61. The end of the pushing spring 62 away from the pushing block 61 is fixed on 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 as a hollow structure to facilitate the pushing block 61 to slide along the axial direction of the rotating shaft 33; the sliding rod 41 is provided with a clearance groove 04, 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, and 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 to the give-way groove 04, and then the vertical pipe is convenient for abutting against the surface of the cross bar.

[0049] When the fixed groove 53 and the pushing block 61 correspond, 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 to disengage from the fixed groove 53, and then the fixed block 51 will no longer fix 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 fixed 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.

[0050] Reference Figures 4 to 6 A pushing surface 05 is provided on the moving rod 31, and the horizontal cross-section of the pushing surface 05 gradually increases along the surface close to the ground. When the lifting assembly 2 drives 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 gradually compress the pushing spring 62. 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. During the movement of the pushing block 61, 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.

[0051] Reference Figures 2 to 4, a connecting assembly 10 is arranged on the frame 01, and the connecting assembly 10 is used to fix the second mounting plate 91 on the frame 01; the connecting assembly 10 includes a mounting block 101 fixed on the frame 01, a connecting block 102 fixed on the second mounting plate 91, and a connecting groove 103 provided on the mounting block 101. When the second clamping assembly 06 is arranged horizontally, the connecting block 102 is in the connecting groove 103, so that the stability of the second clamping assembly 06 can be improved; when the second clamping assembly 06 is arranged vertically, the connecting block 102 is separated from the connecting groove 103. In this embodiment, the connecting block 102 is arranged to be an elastic material, and an abutting surface is arranged on the connecting block 102, so that the connecting block 102 is easy to move into the connecting groove 103.

[0052] 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, one end of the lifting screw 21 is also fixed to the moving rod 31, and a driving assembly 15 for driving the lifting screw 21 to move is provided on the frame 01.

[0053] 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 penetrated by the lifting screw 21 and is threadedly connected to the lifting screw 21. The driving motor 151 rotates to drive the driving gear 152 and the driven gear 153 to rotate, and then drive the lifting screw 21 and the moving rod 31 to slide on the frame 01, thereby driving the second clamping assembly 06 to move up and down in the vertical direction, and then adjust the position of the vertical pipe.

[0054] Reference Figure 1 and Fig. 9When there is no need to weld the three-way pipe, the driving 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 end face of the pipe fixed by the second clamping assembly 06, and finally welding is performed by the welding robot 02, so that two horizontal pipes can be fixedly welded, and the three-way pipe can also be fixedly 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 surface of the pipe 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.

[0055] 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 to abut 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 process of the three-way 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 by 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 and the opening on the vertical pipe can correspond to each other, 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 rear positions, thereby achieving the purpose of automatically adjusting the positions of the cross tube and the vertical tube.

[0056] During manual installation, the opening of the cross tube may be tilted. There are two states of the tilting of the cross tube. 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 proofreading roller 13 upwards so that the proofreading roller 13 moves to the top of the cross tube, and then release the proofreading roller 13. The proofreading roller 13 abuts against the surface of the cross tube under the action of the proofreading spring 14. During the horizontal movement of the cross tube, the proofreading roller 13 has a force to move downward. Then, when the proofreading roller 13 moves to the opening of the cross tube, 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 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 cross tube to rotate, so that the lowest point in front of the cross tube and the lowest point at the rear will abut against the proofreading roller 13. At this time, the opening on the cross tube is facing upward. When the lowest point in front of the cross tube is lower than the lowest point behind the cross tube, the lowest point in front of the cross 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 cross tube to rotate, so that the lowest point in front and the lowest point behind the cross tube will both abut against the proofreading roller 13. At this time, the opening on the cross tube is facing upward, thereby achieving the purpose of proofreading the cross tube opening.

[0057] 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 the vertical tube will be pushed to rotate during the horizontal movement of the horizontal tube. At the same time, the abutment spring 42 also pushes 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 opening position of the vertical tube.

[0058] The implementation principle of a compressor welding device in an embodiment of the present application is as follows: when welding two horizontal compressor pipes, one pipe is fixed by the first clamping assembly 8, and then the other pipe is fixed by the second clamping assembly 06. The adjusting screw 03 is rotated 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. 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.

[0059] 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. During the upward movement of the rotating assembly 3, 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 is lifted and lowered. 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, and the pushing block 61 pushes the fixed block 51 out of the fixed groove 53, and then the sliding rod 14 will move in the vertical direction on the rotating frame, and the abutment spring 42 pushes the vertical pipe to abut the horizontal pipe, and the horizontal pipe continues to move. 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, so as to achieve the purpose of welding the three-way pipe without spot welding, thereby improving work efficiency. In addition, the present equipment can also weld two horizontally arranged pipes to improve the utilization rate of the welding equipment.
