Description

Technical Field

[0001] The present invention relates to the technical field of welding positioning, in particular to intelligent welding equipment for a fire extinguisher tank. Background Art

[0002] The welding of fire extinguisher tanks refers to the metal welding of components such as the cylinder, head, and valve seat. After welding, it is necessary to ensure that the weld has sufficient strength, sealing, and corrosion resistance to ensure that the tank can withstand the specified working pressure after being filled with fire extinguishing agent. At the same time, it avoids the risk of leakage or explosion caused by welding defects (such as pores, cracks, lack of fusion, etc.). It is a key manufacturing link to ensure the safety and reliability of fire extinguishers.

[0003] The utility model with existing publication number CN204771250U discloses a straight seam welding machine for a fire extinguisher cylinder, comprising a frame, a welding carriage, a welding gun adjustment frame, a welding gun and a positioning cylinder. A track is laid on the upper part of the frame, and the welding carriage slides along the track. The welding gun adjustment frame is fixed on the welding carriage, and the welding gun adjustment frame clamps the welding gun; a welding positioning plate is provided in the middle part of the frame, and the positioning cylinder is provided at the bottom of the welding positioning plate. The above scheme fixes the fire extinguisher cylinder by moving the welding mechanism and the positioning cylinder, thereby improving the welding quality and efficiency. Since the fire extinguisher cylinder for seam welding is rolled from a metal sheet during processing, manual labor or a manipulator is required to place the rolled unwelded fire extinguisher cylinder into the linear welding equipment.

Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0037] Please see the attached Figure 1-15 , this application provides the following technical solutions.

[0038] Example 1: An intelligent welding device for a fire extinguisher tank, comprising a welding module 1, a welding cavity 2 being horizontally opened on one side of the welding module 1, a movable welding mounting slot 3 being opened above the welding cavity 2, a fixed mounting seat 4 being inserted and fixed on one side of the welding cavity 2, a welding cantilever seat 5 being provided at the center of one side of the fixed mounting seat 4, the welding cantilever seat 5 being located at the center of the welding cavity 2, a fire extinguisher cylinder 27 being sleeved on the welding cantilever seat 5 through an expansion component and a retraction component, the expansion component comprising eight support rollers 10, and the retraction component comprising three cylinder retraction clamps Plate 39, an adjustment rotation groove 13 is provided in the center of the welding cantilever seat 5, and four makeshift grooves 7 are symmetrically provided on both sides of the welding cantilever seat 5 on the adjustment rotation groove 13.

One side of the support roller 10 extends out of the makeshift groove 7 and contacts the inner circumference of the fire extinguisher cylinder 27. When the fire extinguisher cylinder 27 is sleeved on the welding cantilever seat 5 through the eight support rollers 10, the three cylinders retract the splint 39 away from the fire extinguisher cylinder 27, and the fire extinguisher cylinder 27 can be horizontally supported in rotation.

[0039] A first air inlet groove 6 is provided in the center of the welding cantilever seat 5 through the fixed mounting seat 4, and a plurality of first piston grooves 8 are provided in the first air inlet groove 6 and connected to the yield groove 7. A first piston rod 11 is provided on one side of the support frame 9 located in the first piston groove 8, and the first piston rod 11 is movably inserted in the first piston groove 8. A first spring 12 is provided on one side of the first piston rod 11 located in the first piston groove 8. Three cylinder retraction splints 39 are respectively provided on three sides of the welding cavity groove 2, and the three cylinder retraction splints 39 are away from the movable welding mounting groove 3. When high-pressure airflow is introduced into the first air inlet groove 6, the high-pressure gas supports the plurality of first piston rods 11 of the eight support frames 9. At this time, the eight support rollers 10 push toward the four sides of the welding cantilever seat 5, respectively, so that the inner diameter of the fire extinguisher cylinder 27 expands and changes, and then the unwelded seam of the fire extinguisher cylinder 27 opens to a certain width.

[0040] The alignment adjustment assembly is set so that the unwelded seam of the fire extinguisher cylinder 27 faces upward and corresponds to the movable welding installation groove 3. The alignment adjustment assembly is rotatably sleeved on the welding cantilever seat 5. The alignment adjustment assembly includes an adjustment swivel 14, a lifting box 19 and a T-shaped toggle piece 25. The T-shaped toggle piece 25 is inserted into the unwelded seam of the fire extinguisher cylinder 27. The adjustment swivel 14 is rotated and inserted into the adjustment rotation groove 13 through a sealed bearing. An annular air groove 15 is opened on the inner circumference of the adjustment swivel 14. A connecting groove 16 is opened in the first air inlet groove 6 to connect the annular air groove 15. An inner gear ring 29 is provided on the inner circumference of the adjusting swivel 14 near the fixed mounting seat 4, and a gear groove is opened on one side of the adjusting rotating groove 13 in the welding cantilever seat 5. A rotating gear 28 is rotatably provided in the gear groove, and one side of the rotating gear 28 extends out of the gear groove and is meshed with the inner gear ring 29. The adjusting swivel 14 can rotate in the adjusting rotating groove 13 through a bearing, and the rotation activity is controlled by the meshing of the rotating gear 28 and the inner gear ring 29. When the rotating gear 28 is driven to rotate by the PLC servo stepper motor, the adjusting swivel 14 can rotate.

[0041] A boss 17 is provided on one side of the adjustment ring 14, and a lifting groove 18 is provided on the upper end of the boss 17. A lifting box 19 is horizontally inserted into the lifting groove 18. A second piston groove 20 is provided in the boss 17 to connect the lifting groove 18 and the annular gas groove 15. The lower end of the lifting box 19 located in the second piston groove 20 is provided with a second piston rod 21. The second piston rod 21 is provided with a constraint groove 22 near the upper end of the lifting box 19. A constraint horizontal plate 23 is provided horizontally in the second piston groove 20 through the constraint groove 22. The lower end of the constraint horizontal plate 23 located in the constraint groove 22 is provided with a second Spring 24, a telescopic slot is provided in the lifting box 19, a T-shaped toggle piece 25 is vertically inserted into the upper end of the telescopic slot, and the upper end of the T-shaped toggle piece 25 extends out of the lifting box 19 and is located in the unwelded joint of the fire extinguisher cylinder 27. The T-shaped toggle piece 25 is located in the telescopic slot on one side and is movably connected by a guide rod. The T-shaped toggle piece 25 is located in the telescopic slot and is provided with a plurality of third springs 26 at the lower end. When high-pressure gas is introduced into the first air inlet groove 6, the support roller 10 supports the normal inner diameter of the fire extinguisher cylinder 27. At this time, regardless of the unwelded joint of the fire extinguisher cylinder 27, the support roller 10 supports the normal inner diameter of the fire extinguisher cylinder 27. No matter where the joint is, the lifting box 19 is lowered and placed in the lifting groove 18 under the action of the second spring 24, and the end of the T-shaped toggle piece 25 will not contact the fire extinguisher cylinder 27. When the first air inlet groove 6 is fed with high-pressure gas, the support roller 10 is extended and the lifting box 19 is also lifted, and then the T-shaped toggle piece 25 rotates together. At this time, some T-shaped toggle pieces 25 are not aligned with the unwelded joints of the fire extinguisher cylinder 27. The end of the T-shaped toggle piece 25 will abut against the inner wall of the fire extinguisher cylinder 27, and then the T-shaped toggle piece 25 will not be aligned with the unwelded joints of the fire extinguisher cylinder 27. The movable piece 25 will squeeze the third spring 26 to adapt and retract into the lifting box 19. When the adjusting ring 14 rotates to control the T-shaped toggle piece 25 to reach the unwelded seam position of the fire extinguisher cylinder 27, the T-shaped toggle piece 25 is inserted into the seam, and then the adjusting ring 14 continues to drive the T-shaped toggle piece 25 to rotate. The T-shaped toggle piece 25 can toggle the fire extinguisher cylinder 27 to rotate along the support roller 10. Finally, the T-shaped toggle piece 25 is vertically toward the movable welding mounting groove 3, so that the unwelded seam of the fire extinguisher cylinder 27 is also below the position of the movable welding mounting groove 3.

[0042] Two bottom support placement bars 40 are horizontally provided on the upper end of the welding cantilever seat 5 near the movable welding mounting groove 3. A welding clearance groove 41 is opened at the upper center of the bottom support placement bar 40, and the two bottom support placement bars 40 are respectively located on both sides of the adjustment rotation groove 13. When the joint of the fire extinguisher cylinder 27 is below the movable welding mounting groove 3, the gas in the first air inlet groove 6 is discharged, and the lifting box 19 and the support roller 10 are reset under the action of their respective springs. The T-shaped toggle piece 25 is inside the fire extinguisher cylinder 27 and is lower than the welding clearance groove 41. At this time, the fire extinguisher cylinder 27 is closed at the joint under the action of its own cylindrical elastic reset. During the closing process, the bottom support placement bar 40 can support the inner wall of the joint of the fire extinguisher cylinder 27 to make the joint composite splicing complete. During this period, the three cylinders are used to close the splint 39 to complete the joint docking and the fire extinguisher cylinder 27 is stable and does not shake.

[0043] Embodiment 2: On the basis of embodiment 1, an auxiliary component is provided to mechanically position the position of the adjustment swivel 14, and at the same time, the dust and smoke generated by welding in the welding cavity 2 can be processed. The auxiliary component includes a pushing plug ring 31 and three positioning rods 33. One side of the three positioning rods 33 is respectively inserted into one side of the adjustment swivel 14, and the pushing plug ring 31 is movably inserted into the fixed mounting seat 4. An annular piston groove 30 is provided in the fixed mounting seat 4, and the pushing plug ring 31 is movably arranged in the annular piston groove 30. A second air inlet groove 38 is provided through the end of the annular piston groove 30 away from the welding cantilever seat 5, and a return spring 32 is provided at the end of the pushing plug ring 31 away from the second air inlet groove 38. An annular transfer groove is provided on one side of the annular piston groove 30, and a push-pull ring is provided on one side of the pushing plug ring 31 located in the annular transfer groove. One side of the three positioning rods 33 is respectively connected to one side of the push-pull ring. One side of the positioning rod 33 passes through the welded cantilever seat 5 and is inserted into the adjustment rotating groove 13. Three conical positioning grooves 34 are provided on one side of the adjusting swivel 14. The end of the three positioning rods 33 away from the push-pull ring is a conical structure, and one end of the conical structure of the three positioning rods 33 is respectively inserted into the three conical positioning grooves 34; before the first air inlet groove 6 stops supplying high-pressure air, in order to avoid the error that may be caused by the rotating gear 28 to rotate the adjustment swivel 14, when high-pressure gas is supplied to the position of the second air inlet groove 38, the high-pressure gas enters the annular piston groove 30 and pushes the push ring 31 and the push-pull ring to move toward the welded cantilever seat 5. At this time, the annular piston groove 30 is connected with the annular adapter groove, and the push-pull ring simultaneously pushes one side of the three positioning rods 33 to insert into the conical positioning groove 34 of the adjusting swivel 14. Through the cooperation of the conical structure, the position of the adjusting swivel 14 is precisely positioned.

[0044] An annular drainage groove 35 is provided on one side of the annular adapter groove, and a plurality of suction grooves 36 are provided on one side of the fixed mounting seat 4 located in the welding cavity groove 2. The plurality of suction grooves 36 are respectively connected to the annular drainage groove 35, and a collection cover 37 is provided on one side of the annular drainage groove 35 of the fixed mounting seat 4 through a threaded connection. When the high-pressure airflow is continuously fed into the annular piston groove 30, the positioning rod 33 can be kept inserted into the conical positioning groove 34. In addition, under the action of the annular adapter groove, the high-pressure airflow is discharged horizontally from the annular drainage groove 35, and then when the airflow flows through the annular drainage groove 35, the airflow at the position of the suction groove 36 is pulled, so that the plurality of suction grooves 36 can induce the airflow in the welding cavity groove 2. Since the fire extinguisher cylinder 27 completes welding in the welding cavity groove 2, the welding smoke and exhaust gas generated in the welding cavity groove 2 can be guided by the airflow at the position of the suction groove 36 for unified collection and treatment.
