Description

Technical Field

[0001] This invention relates to the field of welding facilities, and more particularly to a welding robot for processing aluminum parts. Background Technology

[0002] A welding robot is a welding device that automatically completes welding operations through pre-programmed settings or real-time sensor control. Welding robots can precisely control the welding torch trajectory and welding parameters, and are characterized by high efficiency, stability, uniform weld quality, and adaptability to high-risk and repetitive working conditions. Welding robots are frequently used for assembling and welding aluminum components, such as aluminum support parts.

[0003] The support uses three brackets to achieve the supporting function. However, due to the design limitation that the existing welding positioning components can only position one bracket at a time, the actual welding operation has to follow a cycle of welding one bracket, stopping the machine, repositioning the next bracket, and welding again until the assembly and welding of the three brackets are completed. This method of positioning one by one and welding in stages greatly prolongs the overall welding time and directly leads to low efficiency of the support welding process. Summary of the Invention

[0004] The purpose of this invention is to address the shortcomings of the prior art by proposing a welding robot for processing aluminum parts.

[0005] To achieve the above objectives, the technical solution adopted by the present invention is as follows: a welding robot for processing aluminum parts, comprising a carrier and a welding robot installed at the upper rear of the carrier. A lifting and swinging component is installed at the upper front of the carrier, and a pressure sleeve is connected to the end of the lifting and swinging component. A disc is coaxially arranged below the pressure sleeve, and the lower end of the disc is fixed to the carrier. A lifting sleeve is slidably installed at the upper middle of the disc, and three upper positioning columns are fixedly installed in a circular array on the lifting sleeve. The upper edge of the disc... The ring array extends with three lower positioning posts. Three positioning slots are fixedly installed at the upper end of the disc base near the edge. The lower positioning posts and positioning slots are staggered. A pressure sleeve is provided above each of the three upper positioning posts. The pressure sleeve is fixed to the pressure insert. A pressure plate is provided at an angle above each of the three positioning slots. The pressure plate is connected to the pressure insert. A beveled pin is elastically installed through the lower part of the outer surface of the pressure insert. A material fixing hole is opened through the upper part of the outer surface of the lifting insert. The material fixing hole is in the same direction as the beveled pin.

[0006] Preferably, a guide post extends from the upper middle part of the tray base, and a lug extends from the upper edge of the outer surface of the guide post. The upper end of the guide post and the lug are slidably inserted into the inside of the material lifting sleeve.

[0007] Preferably, a solid shell is slidably mounted on the outer surface of the beveled pin, and a grooved cap is coaxially embedded on the outer surface of the beveled pin. The grooved cap is slidably mounted inside the solid shell, and a solid spring is wound around the outer side of the beveled pin. One end of the solid spring is fixed to the grooved cap, and the other end of the solid spring is fixed to the inner wall of the solid shell.

[0008] Preferably, a shell frame is fixedly installed at the upper end of the solid shell, and the end of the shell frame is fixed to the pressing sleeve.

[0009] Preferably, a connecting frame is fixedly installed in the middle of the outer surface of the pressing sleeve, and three bending frames are fixedly installed in a circular array at the end of the connecting frame. The ends of the bending frames are fixed to the pressure plate, and the lower end of the pressing sleeve is flared.

[0010] Preferably, the lifting and tilting component includes a stand fixedly installed at the upper front of the carrier. A threaded rod is rotatably installed inside the stand. A movable seat is screwed onto the outer surface of the threaded rod. A connecting shaft is rotatably installed at the end of the movable seat. A sleeve is fixedly installed at one end of the connecting shaft. The end of the sleeve is fixed to a pressing sleeve. A rotating claw extends from the other end of the connecting shaft. A rotating frame is rotatably installed at the end of the rotating claw. A sliding push seat is rotatably installed at the end of the rotating frame. The sliding push seat is slidably connected to the movable seat. A control claw extends from the upper edge of the side of the stand. The control claw presses against the upper end of the sliding push seat.

[0011] Preferably, a guide frame is fixedly installed on the upper end of the movable seat, and guide ridges extend from both the front and rear ends of the guide frame. The sliding push seat is slidably installed on the outer surface of the guide frame and the outer surface of the guide ridges. A positioning ear extends from the upper end of the guide ridges and fits against the upper end of the sliding push seat.

[0012] Preferably, the end of the threaded rod extends through the upper end of the stand, a servo motor is fixedly installed at the upper end of the stand, the output end of the servo motor is fixed to the end of the threaded rod, a guide rod is fixedly installed inside the stand near the side of the threaded rod, and the movable seat is slidably installed on the outer surface of the guide rod.

[0013] Compared with the prior art, the present invention has the following beneficial effects: 1. Place the lower ring of the support on the plate base. At this time, the three lower positioning pins are inserted into the mounting holes of the lower ring for positioning. Then, place the upper ring of the support on the lifting sleeve. At this time, the upper positioning pins are inserted into the mounting holes of the upper ring for positioning. Next, place the three brackets of the support at an angle into the three positioning slots. At this time, the two ends of the brackets are attached to the upper and lower rings respectively. Then, the downward moving pressing sleeve drives the pressing sleeve and pressing plate to move down, so that the pressing sleeve is fitted onto the upper positioning pin and presses and fixes the upper ring of the support. At the same time, the downward moving pressing plate presses on the middle of the bracket of the support for fixation. In this way, the three brackets of the support and the upper and lower rings are positioned and assembled and welded to shorten the overall welding time and improve the welding efficiency of the support.

[0014] 2. When the pressure sleeve moves downward, it will engage with the lifting sleeve. During engagement, the end of the lifting sleeve will push the beveled pin, causing it to move laterally and retract into the fixed housing. After the pressure sleeve and lifting sleeve are fully engaged, the beveled pin will extend again under the push of the fixing spring to engage in the fixing hole on the lifting sleeve, locking the engaged pressure sleeve and lifting sleeve together. This clamps the support between the pressure sleeve and the lifting sleeve. After the joint on the outside of the support is welded, the moving seat will move the pressure sleeve upward. At this point, the upward-moving pressure sleeve will cause the outer welded support to move upward synchronously, detaching it from the plate. When the moving seat is about to reach its end point, the sliding pusher will press against the control claw to keep it stationary. Then the moving seat continues to move upward. At this time, the transfer frame will move under the push of the sliding pusher to push the transfer claw, thereby driving the connecting shaft to rotate and flip the support so that the bottom of the support faces backward, exposing the inner side of the support to the front of the welding robot, so that the welding robot can weld the seam on the inner side of the support, thus facilitating the welding of all the seams of the support.

[0015] 3. After welding is completed, pull the beveled pin to remove it from the fixing hole, separating the mating pressure sleeve and lifting sleeve, and then loosening the support clamped between the pressure sleeve and lifting sleeve, so that the support can be removed. The process is simple and facilitates material unloading. Attached Figure Description

[0018] The following description is intended to disclose the invention and enable those skilled in the art to implement it. The preferred embodiments described below are merely examples, and other obvious variations will occur to those skilled in the art.

[0019] like Figures 1-8The welding robot for processing aluminum parts shown includes a carrier 1 and a welding robot 2 installed at the upper rear of the carrier 1. Since welding robot 2 performing welding along a preset trajectory is existing technology and widely used, it is not described in detail here. A lifting and swinging component is installed at the upper front of the carrier 1. A pressure sleeve 8 is connected to the end of the lifting and swinging component. A disc base 3 is coaxially arranged below the pressure sleeve 8, serving to support the support 35. The lower end of the disc base 3 is fixed to the carrier 1, and a lifting mechanism is slidably installed at the upper middle of the disc base 3. The material lifting sleeve 6 has three upper positioning posts 13 fixedly installed in a ring array on it. The material lifting sleeve 6 serves to support the upper positioning posts 13. Three lower positioning posts 4 extend in a ring array from the upper edge of the disc base 3. Three positioning slot seats 7 are fixedly installed at an angle near the upper edge of the disc base 3. The lower positioning posts 4 and the positioning slot seats 7 are staggered to avoid the lower positioning posts 4 from obstructing the weld. A pressure sleeve 30 is provided above each of the three upper positioning posts 13. The pressure sleeve 30 is fixed to the material pressing sleeve 8. A pressure plate 31 is inclinedly provided above each of the three positioning slot seats 7. The pressure sleeve 8 is connected, and the lower ring of the support 35 is placed on the plate seat 3. At this time, the three lower positioning pins 4 are inserted into the mounting holes of the lower ring for positioning. Then, the upper ring of the support 35 is placed on the lifting sleeve 6. At this time, the upper positioning pin 13 is inserted into the mounting hole of the upper ring for positioning. Next, the three brackets of the support 35 are tilted and placed in the three positioning slot seats 7 respectively. At this time, the two ends of the brackets are respectively attached to the upper and lower rings. Then, the downward moving pressure sleeve 8 drives the pressure sleeve 30 and the pressure plate 31 to move down, so that the pressure sleeve 30 is fitted onto the upper positioning pin 13 and presses and fixes the upper ring of the support 35. At the same time, it moves down. The pressure plate 31 is pressed against the middle of the bracket of the support 35 for fixation. At the same time, the three brackets and the upper and lower rings of the support 35 are positioned and assembled and welded to shorten the overall welding time and improve the welding efficiency of the support 35. The lower part of the outer surface of the pressure sleeve 8 is elastically installed with a beveled pin 27. The upper part of the outer surface of the lifting sleeve 6 is provided with a fixing hole 32. The fixing hole 32 is in the same direction as the beveled pin 27, which can ensure that the beveled pin 27 is smoothly inserted into the fixing hole 32 to lock the inserted pressure sleeve 8 and lifting sleeve 6, thereby fixing the support 35 so that it can be moved upward in the future.

[0020] A guide post 5 extends from the upper middle part of the plate base 3. A lug 34 extends from the upper edge of the outer surface of the guide post 5. The upper end of the guide post 5 and the lug 34 are slidably inserted into the inside of the lifting sleeve 6. The guide post 5 plays the role of supporting and guiding the lifting sleeve 6. The lug 34 can position the lifting sleeve 6 so that the upper positioning post 13 and the pressure sleeve 30 on the lifting sleeve 6 are aligned.

[0021] A solid shell 24 is slidably mounted on the outer surface of the beveled pin 27, and a groove cap 26 is coaxially embedded on the outer surface of the beveled pin 27. The solid shell 24 and the groove cap 26 serve to guide the beveled pin 27. The groove cap 26 is slidably mounted inside the solid shell 24. A solid spring 25 is wound around the outer side of the beveled pin 27. One end of the solid spring 25 is fixed to the groove cap 26, and the other end of the solid spring 25 is fixed to the inner wall of the solid shell 24. The solid spring 25 serves to push the beveled pin 27 out.

[0022] A housing frame 33 is fixedly installed on the upper end of the solid housing 24. The end of the housing frame 33 is fixed to the pressure sleeve 8. The housing frame 33 serves to fix the solid housing 24.

[0023] A connecting frame 28 is fixedly installed in the middle of the outer surface of the pressing sleeve 8. Three bending frames 29 are fixedly installed in a circular array at the end of the connecting frame 28. The bending design of the bending frame 29 allows the joint of the support 35 to be exposed to avoid being blocked by the bending frame 29. The connecting frame 28 and the bending frame 29 serve to fix the pressure plate 31. The end of the bending frame 29 is fixed to the pressure plate 31. The lower end of the pressing sleeve 8 is set in a trumpet shape, which facilitates the insertion of the pressing sleeve 8 and the lifting sleeve 6. At the same time, the lifting sleeve 6 can also guide the pressing sleeve 8 so that the pressing sleeve 8 moves vertically downward.

[0024] The lifting and tilting component includes a stand 11 fixedly installed at the upper front of the carrier 1. A threaded rod 14 is rotatably installed inside the stand 11, which serves as a load-bearing element. A movable seat 16 is screwed onto the outer surface of the threaded rod 14, which can drive the movable seat 16 to move up and down, thereby driving the pressing sleeve 8 to move up and down. A connecting shaft 10 is rotatably installed at the end of the movable seat 16. A sleeve 9 is fixedly installed at one end of the connecting shaft 10, and the end of the sleeve 9 is fixed to the pressing sleeve 8. The sleeve 9 serves to connect the connecting shaft 10 and the pressing sleeve 8 together. A rotating claw 21 extends from the other end of the connecting shaft 10. A transfer rack 20 is rotatably mounted on the part of the transfer rack 20. A sliding push seat 19 is rotatably mounted on the end of the transfer rack 20. The transfer rack 20 moves under the push of the sliding push seat 19 to push the transfer claw 21, thereby driving the connecting shaft 10 to rotate and flip the support 35 so that the bottom of the support 35 faces the rear, exposing the inner side of the support 35 to the front of the welding robot 2, so that the welding robot 2 can weld the seam on the inner side of the support 35. The sliding push seat 19 is slidably connected to the moving seat 16. A control claw 18 extends from the upper edge of the side of the upright seat 11. The control claw 18 presses against the upper end of the sliding push seat 19, which can keep the sliding push seat 19 stationary.

[0025] A guide frame 17 is fixedly installed on the upper end of the movable seat 16. Guide ribs 22 extend from both the front and rear ends of the guide frame 17. The guide frame 17 and the guide ribs 22 serve to guide the sliding push seat 19. The sliding push seat 19 is slidably installed on the outer surface of the guide frame 17 and the outer surface of the guide ribs 22. A positioning ear 23 extends from the upper end of the guide ribs 22. The positioning ear 23 fits against the upper end of the sliding push seat 19. The positioning ear 23 can limit the sliding push seat 19 so that when the pressure sleeve 8 flips down and resets under its own weight, it can reset to a vertical state.

[0026] The end of the threaded rod 14 extends through the upper end of the stand 11. A servo motor 12 is fixedly installed at the upper end of the stand 11. The servo motor 12 drives the threaded rod 14 to rotate. The output end of the servo motor 12 is fixed to the end of the threaded rod 14. A guide rod 15 is fixedly installed inside the stand 11 near the side of the threaded rod 14. A movable seat 16 is slidably installed on the outer surface of the guide rod 15. The guide rod 15 guides the movable seat 16.

[0027] During welding, the lower ring of the support 35 is placed on the plate seat 3. At this time, the three lower positioning pins 4 are inserted into the mounting holes of the lower ring for positioning. Then, the upper ring of the support 35 is placed on the lifting sleeve 6. At this time, the upper positioning pin 13 is inserted into the mounting hole of the upper ring for positioning. Next, the three brackets of the support 35 are tilted and placed in the three positioning slot seats 7 respectively. At this time, the two ends of the brackets are respectively attached to the upper and lower rings. Then, the servo motor 12 drives the threaded rod 14 to rotate, thereby driving the pressure sleeve 8 on the moving seat 16 to move down. The moving pressure sleeve 8 drives the pressure sleeve 30 and the pressure plate 31 to move down, so that the pressure sleeve 30 is fitted onto the upper positioning pin 13 and supports the upper ring of the support 35. The ring is pressed and fixed, and the downward-moving pressure plate 31 presses against the middle of the support 35 for fixation. When the pressure sleeve 8 moves downward, the pressure sleeve 8 will engage with the lifting sleeve 6. During the engagement process, the end of the lifting sleeve 6 will push the inclined pin 27, causing the inclined pin 27 to move laterally using its inclined end and retract into the fixed housing 24. After the pressure sleeve 8 and the lifting sleeve 6 are fully engaged, the inclined pin 27 will extend again under the push of the fixed spring 25 to engage in the fixed hole 32 on the lifting sleeve 6, locking the engaged pressure sleeve 8 and lifting sleeve 6, thereby clamping the support 35 into the pressure sleeve 30. Between the material lifting sleeve 6 and the support 35, the three brackets and upper and lower rings of the support 35 are positioned simultaneously. Then, the welding robot 2 can be used to weld the seam on the outside of the support 35. After the seam on the outside of the support 35 is welded, the moving seat 16 will drive the pressure sleeve 8 to move upward. At this time, the moving pressure sleeve 8 will drive the support 35, which has been welded on the outside, to move upward synchronously, so that it is detached from the plate seat 3. When the moving seat 16 is about to move to the end point, the sliding push seat 19 will press against the control claw 18 to keep it stationary. Then the moving seat 16 continues to move upward. At this time, the transfer frame 20 will move under the push of the sliding push seat 19 to push the transfer claw 21. This causes the connecting shaft 10 to rotate, thereby flipping the support 35 so that the bottom of the support 35 faces backward, exposing the inner side of the support 35 to the front of the welding robot 2. This allows the welding robot 2 to weld the seams on the inner side of the support 35. After all the seams of the support 35 are welded, the inclined pin 27 is pulled to remove it from the material fixing hole 32, separating the inserted pressure sleeve 8 and lifting sleeve 6. This loosens the support 35 clamped between the pressure sleeve 30 and the lifting sleeve 6, allowing the support 35 to be removed. The separated lifting sleeve 6 is then re-inserted onto the guide post 5, ready for the next welding operation.
