Description

Technical Field

[0001] The present invention relates to the technical field of positioners, and specifically to a heavy-duty horizontal rotary three-axis welding positioner. Background Art

[0002] A positioner is a welding auxiliary device used for the welding position change of rotating workpieces to obtain an ideal processing position and welding speed. Generally, a positioner is provided with two ends, one end is a welding station, and the other end is a loading and unloading station. During use, the positions of the two ends are continuously changed by the rotation of the positioner, so as to achieve continuous loading and processing.

[0003] When welding and processing is carried out at one end of the positioner, loading and unloading of parts is carried out at the other end. In order to keep the height of the welding station unchanged, the two stations are generally set at the same height, which makes it very inconvenient during the loading process. It is necessary to bend down in accordance with the height of the station. When encountering heavy parts, it is also necessary to manually carry the heavy parts to a higher station, and the loading and unloading is very inconvenient. In addition, for a positioner device with adjustable station height, it is impossible to keep the same height after the station returns to the welding machine position, and the height difference between the part and the welding device is unstable, which easily causes the quality of the welded products to be inconsistent. Summary of the Invention

[0004] The technical problem of the present invention is to provide a heavy-duty horizontal rotary three-axis welding positioner and briefly summarize the innovation points.

A plurality of vertical rods are evenly arranged on the outer surface of the driven disk. After the shifting rods rotate, they can be embedded between the vertical rods of the driven disk to drive the driven disk to rotate.

[0007] As a further solution of the present invention, an embedding rod is fixedly installed on one side of the mounting plate close to the notch plate and corresponding to the notch of the notch plate. A plurality of embedding grooves are provided on the driven plate. The embedding grooves are perpendicular to each other. The embedding grooves match the embedding rod.

[0008] As a further solution of the present invention, the driving rod is rotatably installed on the lower surface of the side mounting frame. A lower transmission member is provided between the lower surface of the side mounting frame and the lower surface of the driven disk. The upper end of the driving rod extends into the side mounting frame. A lower bevel gear is fixedly installed on the driving rod. A side bevel gear is fixedly installed at one end of the driven rod close to the driving rod. The side bevel gear meshes with the lower bevel gear. The lower transmission member is composed of a driven gear, a driving gear, a central gear and a transmission chain. The central gear is arranged on the lower surface of the driven disk. The driving gear is arranged on the lower surface of the driven disk and its upper end meshes with the central gear. The driven gear is fixedly installed at the lower end of the driving rod. A transmission chain is sleeved outside the lower end of the driving gear and the driven gear.

[0009] As a further solution of the present invention, a welding baffle is fixedly installed on the upper surface of the middle mounting frame. A cleaning scraper is slidably installed on the outer surface of the welding baffle. A threaded rod is rotatably installed in the middle mounting frame. Both ends of the threaded rod extend into the side mounting frame. The lower end of the cleaning scraper is threadedly connected to the threaded rod. Driving components are arranged at both ends of the threaded rod. The driving components can drive the cleaning scraper to slide on the surface of the welding baffle while the middle mounting frame rotates.

[0010] As a further solution of the present invention, the driving component includes an upper transmission member and a driven bevel gear.

[0011] As a further solution of the present invention, a micro motor is arranged in the support seat. The output end of the micro motor is fixedly connected to the rotating frame. The rotating frame is detachably installed with a positioning device. A pressure sensor is fixedly installed on the positioning device.

[0012] As a further solution of the present invention, the intermediate mounting frame is fixedly mounted on the upper surface of the driven disk, and a controller and an information transmission module are installed in the intermediate mounting frame. The information transmission module is electrically connected to the pressure sensor, and the drive motor can drive the active disk to rotate in both directions. The distribution angle of the toggle rod on the active disk is less than 180 degrees.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] The present invention drives the driven rod to rotate through the driving mechanism, so that the height of the rotating frame is adjusted according to the weight of the parts during the replacement process of the welding rotating frame. If the weight of the welding parts is greater than the set value, the connecting plate is driven to rotate downward, so that the rotating frame moves downward from the welding height to be close to the ground, avoiding the trouble of carrying heavy welding parts to the rotating frame at the welding height, so that the loading and unloading of heavy welding parts can be carried out at a position close to the ground height, saving physical energy consumption of the staff. If the weight of the welding parts is less than the set value, the connecting plate is driven to rotate upward, so that the rotating frame moves upward from the welding height, so that the rotating frame is close to the height that is convenient for the staff to operate, avoiding the user to bend over to disassemble and assemble the welding parts, making the disassembly and assembly of the welding parts more convenient.

[0015] The present invention drives the driven disk to rotate by the rotation of the active disk, and automatically controls the processing time of heavy parts and small parts by the continuous rotation of the active disk and the forward and reverse rotation of the active disk, so that the processing time of small parts is shorter and the processing time of heavy parts is longer. The small and heavy parts to be processed are distinguished from the left and right inclinations of the connecting plate, which is convenient for the welding device to perform processing and avoids the trouble of manually adjusting the welding device after changing the part model.

[0016] The present invention ensures that the driven plate is automatically locked after rotating a certain angle through the cooperation between the embedded groove in the driven plate and the embedded rod and notched plate on the mounting plate. The driven plate can ensure that the connecting plate rotates the same angle each time, thereby ensuring that the rotating frame in the welding position is always at the same horizontal height, avoiding the welding equipment from misjudging the processing position of the welding part due to the change in the position height of the rotating frame, thereby causing defects in the processing of the welding part, and ensuring the uniformity and processing quality of the welding parts.

[0028] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without making creative efforts belong to the scope of protection of the present invention.

[0029] Please refer to Figures 1 - 8, the present invention provides a technical solution: a heavy-duty horizontal rotary three-axis welding positioner, including a mounting base 1 and an intermediate mounting frame 5. A driving mechanism is provided on the upper surface of the mounting base 1, and the driving mechanism can drive the intermediate mounting frame 5 to rotate periodically. Side mounting frames 4 are fixedly installed on both sides of the intermediate mounting frame 5. A driven rod 21 is rotatably installed on the lower surface of the side mounting frame 4. One end of the driven rod 21 is fixedly installed with a mounting plate 10. A notched plate 12 is fixedly installed on the mounting plate 10. Mounting shafts 16 are rotatably connected to both ends of the side mounting frame 4. A driven plate 14 is fixedly installed on the mounting shaft 16. The driven plate 14 can drive the lower part to rotate 90 degrees and then automatically lock through the mounting plate 10. A connecting plate 11 is fixedly installed on the mounting shaft 16. A support seat 3 is rotatably installed at one end of the connecting plate 11 away from the mounting shaft 16. A rotating frame 2 is rotatably installed between the support seats 3.

[0030] Before the present invention is used, first assemble the device completely. As Figure 1 shown, looking down from the upper direction of the figure is the upper end of the device, and looking from the left to the right of Figure 1 is the left end of the device. After that, the equipment orientation is used for description and will not be elaborated.

[0031] During operation, the driving mechanism drives the intermediate mounting frame 5 to rotate 180 degrees regularly, and the positions of the rotating frames 2 at both ends of the side mounting frame 4 are exchanged through the rotation of the intermediate mounting frame 5. (As Figure 1 shown, the position where the rotating frame 2 on the side away from the driving disc 8 is located is the welding processing position, and the position where the rotating frame 2 on the side close to the driving disc 8 is located is the workpiece loading and unloading position). The driving mechanism enables the two rotating frames 2 to exchange positions regularly, so as to perform exchange welding. During the process of the driving mechanism driving the intermediate mounting frame 5 to rotate, the driving mechanism also drives the driven rod 21 to rotate. The driven rod 21 rotates during the position exchange of the two rotating frames 2 driven by the driving mechanism. The rotation of the driven rod 21 drives the mounting plate 10 to rotate, and the mounting plate 10 drives the driven plate 14 to rotate. The rotation of the driven plate 14 drives the mounting shaft 16 to rotate, so that the mounting shaft 16 drives the connecting plate 11 to rotate. The connecting plate 11 rotates 90 degrees under the drive of the mounting shaft 16 and moves up or down from the welding processing position. If the gravity of the welding part is greater than the set value, the connecting plate 11 is driven to rotate downward, so that the rotating frame 2 moves downward from the welding height and approaches the ground, which is convenient for the user to disassemble and install heavy parts and saves the trouble of lifting heavy parts upward. If the gravity of the welding part is less than the set value, the connecting plate 11 is driven to rotate upward, so that the rotating frame 2 moves upward from the welding height, and the rotating frame 2 approaches the height convenient for the operator, which is convenient for the user to disassemble and load materials.

[0032] In the present invention, a driving mechanism drives the driven rod 21 to rotate, so as to adjust the height of the welding rotating frame 2 according to the gravity of the part during the rotation of the welding rotating frame 2. When the gravity of the welding part is greater than the set value, the driving connecting plate 11 rotates downward, so that the rotating frame 2 moves downward from the welding height and approaches the ground, avoiding the trouble of transporting heavy welding parts to the rotating frame 2 at the welding height. The loading and unloading of heavy welding parts can be carried out at a position close to the ground height, saving the physical consumption of the staff. If the gravity of the welding part is less than the set value, the driving connecting plate 11 rotates upward, so that the rotating frame 2 moves upward from the welding height, making the rotating frame 2 close to the height convenient for the operator to operate, avoiding the user bending down to disassemble and assemble the welding part, and making the disassembly and assembly of the welding part more convenient.

[0033] As a further solution of the present invention, the driving mechanism includes a driving motor 17 and a driving rod 22. The driving motor 17 is fixedly installed on the upper surface of the mounting seat 1. The output end of the driving motor 17 is fixedly installed with a driving disc 8. The lower edge of the driving disc 8 is evenly provided with a shifting rod 19. The upper surface of the driving motor 17 is fixedly installed with a fixing seat 20. The upper surface of the fixing seat 20 is rotatably connected with a driven disc 9. The outer surface of the driven disc 9 is evenly provided with a plurality of vertical rods. After the shifting rod 19 rotates, it can be embedded between the vertical rods of the driven disc 9 to drive the driven disc 9 to rotate.

[0034] During operation, the driving motor 17 rotates to drive the driving disc 8 to rotate. The rotation of the driving disc 8 causes the shifting rod 19 to gradually approach the driven disc 9. The shifting rod 19 pushes the vertical rod on the driven disc 9, thereby driving the rotation of the driven disc 9. When the shifting rod 19 starts to move away from the vertical rod, the driven disc 9 just rotates 180 degrees under the drive of the shifting rod, realizing the position exchange of the two end rotating frames 2. At this time, the welded parts on the rotating frame 2 at the loading and unloading position move to the welding station for processing, while the rotating ring at the welding processing position rotates to the loading and unloading position for part disassembly and loading or part position adjustment. At this time, the driving disc 8 continues to rotate, and during the rotation, the shifting rod 19 does not contact the vertical rod. After rotating for a certain period of time, the shifting rod 19 contacts the vertical rod again, so that the shifting rod 19 drives the driven disc 9 to rotate again by pushing the vertical rod, thereby realizing the position exchange of the rotating ring frame again. The user performs a new round of loading and part adjustment, which can ensure that the interval time of each rotation of the driven disc 9 is consistent, ensuring that the welding time of the welded parts remains the same. At the same time, during the welding process, the rotation direction of the driving motor 17 remains unchanged during the welding of lightweight parts (at this time, when the connecting plate 11 is in the horizontal position, it inclines to the left end of the device). At this time, the driving disc 8 rotates continuously in the same direction. At this time, the interval time of the alternating processing of the rotating frame 2 is a single cycle, and the processing time is short. During the welding of heavy parts, after the rotating frame 2 alternates (at this time, when the connecting plate 11 is in the horizontal position, it inclines to the right end of the device), after the shifting rod 19 of the driving disc 8 approaches the driven disc 9 again after one cycle, the driving motor 17 immediately rotates in the reverse direction, and then the driving disc 8 rotating in the reverse direction drives the driven disc 9 to rotate again, performing another rotation frame 2 alternation to increase the welding time for heavy part processing.

[0035] In the present invention, the driving disc 8 rotates to drive the driven disc 9 to rotate. The continuous rotation and forward and reverse rotation of the driving disc 8 are used to automatically control the processing time of heavy parts and small parts, so that the processing time of small parts is shorter and the processing time of heavy parts is longer. The left and right inclinations of the connecting plate 11 are used to distinguish between small and heavy processed parts, which is convenient for the welding device to process and avoids the trouble of manually adjusting the welding device after changing the part model.

[0036] As a further solution of the present invention, an embedding rod 13 is fixedly installed on one side of the mounting plate 10 close to the notch plate 12 and corresponding to the notch of the notch plate 12. A plurality of embedding grooves 15 are provided on the driven plate 14. The embedding grooves 15 are perpendicular to each other. The embedding grooves 15 match the embedding rod 13. The edge of the driven plate 14 corresponding to the embedding grooves 15 is a curved surface, and the edge of the curved surface fits with the edge of the notch plate 12.

[0037] During operation, the driven rod 21 rotates to drive the mounting plate 10 to rotate. The rotation of the mounting plate 10 drives the embedding rod 13 and the notch plate 12 thereon to rotate simultaneously. The rotation causes the contact edge between the notch plate 12 and the driven plate 14 to gradually move away, so that the notch of the notch plate 12 approaches the driven plate 14. When the edge of the notch plate 12 completely disengages from the curved surface edge of the driven plate 14, the embedding rod 13 slides into the embedding groove 15 of the driven plate 14 as the mounting plate 10 rotates. At this time, the embedding rod 13 continues to rotate with the mounting plate 10, and the contact between the edge of the driven plate 14 and the edge of the notch plate 12 disappears. The restrictive effect of the notch plate 12 on the driven plate 14 disappears, and the driven plate 14 rotates driven by the embedding rod 13. When the driven plate 14 rotates 90 degrees, the edge of the notch plate 12 contacts the curved surface of the driven plate 14 again, thus restricting the rotation of the driven plate 14. At this time, the mounting plate 10 continues to rotate, causing the embedding rod 13 to slide out downward from the embedding groove 15. At this time, the edge of the notch plate 12 contacts the curved surface edge of the driven plate 14, restricting the rotation of the driven plate 14. (As Figure 1 shown, the connecting plate 11 on the rotating frame 2 in the loading position is in the vertical state, and the rotating frame 2 in the welding position is in the horizontal state). When the rotating ring after loading returns to the welding position, the connecting plate 11 needs to rotate to the horizontal position for welding each time. The driven plate 14 can ensure that the connecting plate 11 rotates the same angle each time, so as to ensure that the rotating frame 2 in the welding position is always at the same horizontal height, avoiding misjudgment of the processing position of the welded parts by the welding equipment due to the change in the position height of the rotating frame 2, and further causing defects in the processing of the welded parts, and ensuring the unity and processing quality of the welded parts.

[0038] Through the cooperation between the embedding groove 15 in the driven plate 14, the embedding rod 13 and the notch plate 12 on the mounting plate 10, the present invention ensures that the driven plate 14 automatically locks after rotating a certain angle. The driven plate 14 can ensure that the connecting plate 11 rotates the same angle each time, so as to ensure that the rotating frame 2 in the welding position is always at the same horizontal height, avoiding misjudgment of the processing position of the welded parts by the welding equipment due to the change in the position height of the rotating frame 2, and further causing defects in the processing of the welded parts, and ensuring the unity and processing quality of the welded parts.

[0039] As a further solution of the present invention, the active rod 22 is rotatably installed on the lower surface of the side mounting frame 4. A lower transmission member 23 is provided between the side mounting frame 4 and the lower surface of the driven disk 9. The upper end of the active rod 22 extends into the side mounting frame 4. A lower bevel gear 24 is fixedly installed on the active rod 22. One end of the driven rod 21 close to the active rod 22 is fixedly installed with a side bevel gear 25. The side bevel gear 25 meshes with the lower bevel gear 24. The lower transmission member 23 is composed of a driven gear, a driving gear, a central gear and a transmission chain. The central gear is arranged on the lower surface of the driven disk 9. The driving gear is arranged on the lower surface of the driven disk 9 and its upper end meshes with the central gear. The driven gear is fixedly installed at the lower end of the active rod 22. The lower end of the driving gear and the outer sleeve of the driven gear are connected with a transmission chain.

[0040] During operation, the rotation of the driven disk 9 drives the rotation of the intermediate mounting frame 5 and the side mounting frame 4. At the same time, the rotation of the driven disk 9 drives the rotation of the central gear in the lower transmission member 23. The rotation of the central gear drives the rotation of the driving gear meshing with it. The driving gear drives the rotation of the driven gear through the transmission chain. The rotation of the driven gear drives the rotation of the active rod 22. The rotation of the active rod 22 drives the rotation of the lower bevel gear 24. The rotation of the lower bevel gear 24 drives the rotation of the side bevel gear 25 meshing with it. The rotation of the side bevel gear 25 drives the rotation of the driven rod 21. The rotation of the driven rod 21 drives the rotation of the mounting plate 10, and finally drives the rotation of the connecting plate 11 to drive the rotation of the rotating frame 2, so as to adjust the height of the rotating frame 2.

[0041] As a further solution of the present invention, a welding baffle 7 is fixedly installed on the upper surface of the intermediate mounting frame 5. A cleaning scraper 6 is slidably installed on the outer surface of the welding baffle 7. A threaded rod 26 is rotatably installed in the intermediate mounting frame 5. Both ends of the threaded rod 26 extend into the side mounting frame 4. The lower end of the cleaning scraper 6 is threadedly connected to the threaded rod 26. Driving components are arranged at both ends of the threaded rod 26. The driving components can drive the cleaning scraper 6 to slide on the surface of the welding baffle 7 while the intermediate mounting frame 5 is rotating.

[0042] During operation, while the driven rod 21 is rotating, the driven rod 21 drives the upper bevel gear 28 at its upper end to rotate. The rotation of the upper bevel gear 28 drives the rotation of the driven bevel gear 18 meshing with it. The driven bevel gear 18 drives one side of the threaded rod 26 to rotate through the driving member 29. The rotation of the threaded rod 26 makes the cleaning scraper 6 move from one end of the threaded rod 26 to the other end of the threaded rod 26, so that the cleaning scraper 6 moves from one end of the welding baffle 7 to the other end of the welding baffle 7, and further enables the cleaning scraper 6 to clean the surface of the transparent welding baffle 7, avoiding the pollution of the welding baffle 7 during the processing and affecting the observation of the welding process by the staff.

[0043] As a further solution of the present invention, the driving component includes an upper driving member 27 and a driven bevel gear 18. The driven bevel gear 18 is rotatably installed in the side mounting frame 4. The upper end of the driving rod 22 is fixedly installed with an upper bevel gear 28. The upper bevel gear 28 meshes with the driven bevel gear 18. The upper driving member 27 is arranged between the threaded rods 26. A driving member 29 is arranged between one side of the upper bevel gear 28 and the threaded rod 26. Both the driving member 29 and the upper driving member 27 are composed of a transmission belt and two groups of transmission wheels.

[0044] As a further solution of the present invention, a micro motor is arranged in the support base 3. The output end of the micro motor is fixedly connected to the rotating frame 2. The rotating frame 2 is detachably installed with a positioning device. A pressure sensor is fixedly installed on the positioning device.

[0045] During operation, the micro motor in the support base 3 drives the rotating frame 2 to rotate, so as to adjust the angle of the welding parts on the rotating frame 2, facilitating the welding device to weld the welding parts from multiple angles and in multiple directions.

[0046] As a further solution of the present invention, the intermediate mounting frame 5 is fixedly installed on the upper surface of the driven disk 9. A controller and an information transmission module are installed in the intermediate mounting frame 5. The information transmission module is electrically connected to the pressure sensor. The driving motor 17 can drive the driving disk 8 to rotate bidirectionally. The distribution angle of the shifting rods 19 on the driving disk 8 is less than 180 degrees.

[0047] During operation, the pressure sensor on the rotating frame 2 detects the pressure of the welding articles on the rotating frame 2. The pressure sensor transmits the pressure information to the controller and the information transmission module. After analyzing the pressure information through the information transmission module, the rotation direction of the driving motor 17 is controlled. When the pressure value of the welding parts on the pressure sensor is greater than the set value, the driving motor 17 drives the connecting plate 11 to rotate downward, so that the rotating ring is close to the ground when returning to the loading and unloading position, avoiding the trouble of lifting heavy parts upward and facilitating the loading and unloading of heavy parts. When the pressure value of the welding parts on the pressure sensor is less than the set value, the driving motor 17 drives the connecting plate 11 to rotate upward, so that the height of the rotating frame 2 is at a height convenient for the user to operate when returning to the loading and unloading position.
