Description

Technical Field

[0002] The ladle is a common auxiliary equipment commonly used in the casting field in the prior art. The molten metal is added into the ladle, and then the ladle is moved into the range of multiple forming molds in turn, the ladle is tilted toward the forming mold, and then the molten metal in the ladle is poured into the multiple forming molds to complete the casting operation of the molten metal. In the production and processing of the ladle, after the main body of the ladle is formed, a plurality of auxiliary parts will be installed on the ladle using a welding process. The various auxiliary parts include a molten metal feeding port and related structures in the molten metal feeding port, a molten metal pouring port and related structures, an exhaust port and related structures, and a connecting structure connected to the boom equipment. All of the related auxiliary parts need to be welded to the main body of the ladle using a welding process.

[0003] However, because there are many kinds of steel accessories welded and installed on the ladle, and each steel accessory is heavy, various welding toolings are usually used to assist in welding the steel accessories on the ladle, so that the steel accessories and the corresponding positions of the ladle body can be welded. However, according to the actual application of welding tooling in the prior art, because multiple steel accessories need to be welded to different areas of the ladle body, and because the ladle body has a very heavy mass, it is not convenient to adjust the position of the ladle body during the welding process. In addition, because the shape of the ladle accessories is irregular, it is often necessary to tilt the ladle body at some angles during the welding process so that the processing personnel can use welding guns and other equipment to effectively weld the dead angle area between the ladle body and the ladle accessories. When implementing the above-mentioned welding process, the welding tooling in the prior art is difficult to meet the welding requirements between the ladle body and the ladle accessories with sufficient convenience.

Therefore, it should not be understood as a limitation on the present invention.

[0037] In addition, in the description of the present application, the terms "first", "second", etc. are only used to distinguish the description and cannot be understood as indicating or implying relative importance.

[0038] like Figures 1 to 9As shown, the present invention discloses a welding device for welding and installing auxiliary parts of a ladle, including a welding device 1 and a mounting frame 2. The welding device 1 is arranged on one side of the mounting frame 2. During the use of the present invention, multiple welding devices 1 can be installed around the mounting frame 2. Because in the actual welding process of the ladle main body and the ladle auxiliary parts, multiple welding points are generally welded between the auxiliary parts and the main body first to basically fix the position of the auxiliary parts, and then the ladle main body can be rotated to make the main body and the auxiliary parts at other positions on the discharge chute frame 7 correspond to each other in position, so that after preliminary welding between the multiple auxiliary parts and the main body, multiple welding devices 1 are used to perform a thorough welding operation between the auxiliary parts and the main body.

[0039] like Figures 1 to 3 As shown, it also includes a fixed drum 3, which is rotatably arranged in the mounting frame 2 through a rotating shaft seat 4. A bottom clamping mechanism for clamping the bottom of the ladle body is rotatably arranged on the fixed drum 3, and a plurality of side clamping structures for clamping the side walls of the ladle are arranged on the top of the bottom clamping mechanism. The outer side of the bottom clamping mechanism is rotatably connected with a fixed ring sleeve 5. In actual use, the bottom of the ladle body is first clamped by the bottom clamping mechanism, and then the ladle body is turned over along the center point of the fixed drum 3. Multiple ladle accessories can be welded to corresponding positions on the ladle body in sequence. By using the side clamping structure, the corresponding positions on the ladle body can be fixed, so that the ladle body can remain stable during the rotation of the bottom clamping mechanism.

[0040] like Figures 1 to 4 As shown, the bottom clamping mechanism includes a rotating cylinder 8, a bucket-shaped mounting cylinder 9 and a main clamping member. The rotating cylinder 8 is rotatably connected to the fixed rotating cylinder 3, and the fixed ring sleeve 5 is rotatably connected to the rotating cylinder 8. A driving gear ring 36 is provided on the outer wall of the rotating cylinder 8, and a transmission gear is meshed with the driving gear ring 36. A gear transmission box 37 and a first driving motor 38 are provided on the fixed rotating cylinder 3. The transmission gear is arranged on the gear transmission box 37. The output end of the first driving motor 38 is matched with the gear transmission box 37. When it is necessary to drive the rotating cylinder 8 to rotate, the first driving motor 38 is started, and the rotating cylinder 8 is driven to rotate along the center point of the fixed rotating cylinder 3 through the transmission effect between the gear transmission box 37, the transmission gear and the driving gear.

[0041] The bucket-shaped mounting cylinder 9 is fixedly connected to the rotating cylinder 8, and a mounting chamber 10 is formed between the outer arc surface of the bucket-shaped mounting cylinder 9 and the inner wall of the rotating cylinder 8. A plurality of through-movement openings are provided on the bucket-shaped mounting cylinder 9, and a main body clamping member is slidably provided in each through-movement opening. An inclined moving structure is provided between the main body clamping member and the mounting chamber 10. In the process of moving the ladle body into the bucket-shaped mounting cylinder 9, the inner bottom wall of the ladle body is brought into contact with the main body clamping member, and the main body clamping member is moved downward along the through-movement opening corresponding to the inclined inner wall of the bucket-shaped mounting cylinder 9, and the main body clamping member is fully in contact with the inner bottom wall and bottom side wall of the ladle body, so that the ladle body is clamped between the plurality of main body clamping members;

[0042] The main body clamping member includes a bottom support plate 11 and a top clamping body 12. The top clamping body 12 is fixedly connected to the bottom support plate 11. The bottom wall of the ladle body contacts the top of the bottom support plate 11. The top clamping body 12 clamps the side wall of the bottom of the ladle body. During the descent of the ladle body, the inner bottom wall of the ladle body will directly contact the top of the bottom support plate 11. The ladle body will squeeze the bottom support plate 11 and move downward during the hoisting process. In the process of driving the ladle body downward, the top clamping body 12 clamps the ladle body.

[0043] The tilting movement structure includes an inclined slide rail 13, a rotating ball sliding block 14 and a vertical slide rail 15. The inclined slide rail 13 is fixedly connected to the installation chamber 10. The inclination angle of the inclined slide rail 13 is consistent with the inclination angle of the outer wall of the bucket-shaped installation cylinder 9. The rotating ball sliding block 14 is slidably connected to the inclined slide rail 13. The bottom support plate 11 is fixedly connected to the rotating ball sliding block 14. The vertical slide rail 15 is fixedly connected to the installation chamber 10. The top clamping body 12 is slidably connected to the vertical slide rail 15 through a telescopic rod 16. A spring damper 17 is provided between the telescopic rod 16 and the vertical slide rail 15. When the ladle body drives the multiple bottom support plates 11 to descend, the bottom support The plate body 11 drives the rotating ball sliding block 14 to descend on the inclined slide rail 13. Rotating balls are rotatably provided on both sides of the rotating ball sliding block 14. The rotating balls contact the inner wall of the inclined slide rail 13, so that the rotating ball sliding block 14 can drive the bottom supporting plate body 11 to move downward along the moving path of the inclined slide rail 13, so that the top clamping body 12 gradually contacts the side wall of the ladle body to clamp the ladle body. During the descent of the top clamping body 12, the telescopic rod 16 compresses the spring damper 17 to contract, and as the telescopic rod 16 extends and retracts, it adapts to the change in the distance between the top clamping body 12 and the vertical slide rail 15 during the descent of the top clamping body 12.

[0044] like Figures 1 to 2 and Figure 5As shown, the side clamping structure includes an inclined sliding groove frame 18 and a clamping seat 20. The inclined sliding groove frame 18 is fixedly connected to the rotating cylinder 8. A sliding groove body 19 is longitudinally slidably provided on the inclined sliding groove frame 18. The clamping seat 20 is slidably connected in the sliding groove body 19. The top of the sliding groove body 19 is rotatably connected to a pushing screw, which is threadedly connected to the top of the sliding groove frame. An elastic seat 21 is provided between the clamping seat 20 and the sliding groove body 19. The bottom of the inclined sliding groove frame 18 is inclined toward the direction of the rotating cylinder 8. After the ladle body is fixed between the multiple top clamping bodies 12, the hoisting operation of the ladle body by the hoisting equipment cannot be released temporarily. The pushing screw is rotated to drive the sliding trough body 19 and the clamping seat 20 to descend together. The sliding trough body 19 descends along the inclination angle of the sliding trough frame, so that the clamping seat 20 gradually contacts the corresponding position of the ladle body, and then clamps the ladle body. The elastic seat 21 can make the clamping seat 20 more elastic, thereby improving the clamping effect of the clamping seat 20 on the ladle body.

[0045] It should be further explained that, because multiple side clamping structures will cause some welding dead angles on the ladle body when clamping the ladle body, in order to maintain sufficient and stable fixed clamping operation of the ladle body, multiple side clamping structures are kept evenly distributed on the rotating cylinder 8. Only two side clamping structures are shown in the drawings of the present invention. However, in real life, the number of installed side clamping structures on the rotating cylinder 8 is not limited. When it is necessary to fully perform welding operations on multiple positions on the ladle body, multiple side clamping structures are required to clamp different positions on the ladle body. The clamping seat 20 is moved upward by rotating the pushing screw, so that the clamping seat 20 suspends the clamping operation of the ladle body, and then drives the rotating cylinder 8 and the ladle body to rotate, so that the clamping seat 20 corresponds to the remaining positions of the ladle body, and the pushing screw is used to drive the clamping seat 20 to move, so that the clamping seat 20 clamps the ladle body and continues to clamp the ladle body.

[0046] like Figures 1 to 2 and Figure 6As shown, both sides of the top of the mounting frame 2 are slidably connected with sliding seats 22, the lifting trough frame 6 is fixedly connected to the sliding seat 22 located on the same side, and the material discharging trough frame 7 is fixedly connected to one of the sliding seats 22, and one side of the top of the mounting frame 2 is fixedly connected with a balancing slide bar 39, and the other side of the top of the mounting frame 2 is rotatably connected with a driving screw 40. A second driving motor 41 is also provided on the top of the mounting frame 2, and the output end of the second driving motor 41 is fixedly connected to the driving screw 40, one of the sliding seats 22 is slidably connected to the balancing slide bar 39, and the other sliding seat 22 is threadedly connected to the driving screw 40. When it is necessary to drive the material discharging trough frame 7 and the two lifting trough frames 6 to move laterally, the second driving motor 41 is started to drive the driving screw 40 to rotate, so that the sliding seat 22 moves laterally on the top of the mounting frame 2, so that the lifting trough frame 6 drives the fixed ring sleeve 5 to start to deviate;

[0047] The lifting trough frame 6 is slidably connected to the lifting trough frame 6 on both sides of the interior of the mounting frame 2, and a height adaptation structure is provided between the fixed ring sleeve 5 and the lifting trough frame 6. During the horizontal movement of the lifting trough frame 6 in the mounting frame 2, the fixed rotating drum 3, the bottom clamping mechanism, the side clamping structure and the ladle body are offset along the center point of the rotating shaft seat 4. The height adaptation structure includes a runner sliding block 23 and a rotating shaft 24. The runner sliding block 23 is longitudinally slidably arranged in the lifting trough frame 6, and the outer arc surface of the fixed ring sleeve 5 is fixedly connected to the rotating shaft 24. The rotating shaft 24 is rotatably connected to the runner sliding block 23. During the movement of the lifting trough frame 6, the runner sliding block 23 moves longitudinally in the lifting trough frame 6, so that the rotating shaft 24 rotates in the runner sliding block 23. The side of the runner sliding block 23 is provided with a runner, which contacts the inner wall of the lifting trough frame 6. During the horizontal movement of the lifting trough frame 6, the fixed ring sleeve 5, the rotating cylinder 8, the fixed rotating drum 3 and the ladle body are offset along the center point of the rotating shaft seat 4;

[0048] By using the above scheme, the main body of the ladle can be tilted. First, because the external shapes of many ladle accessories are special-shaped structures, and there are also many structures for welding in holes and grooves, the main body of the ladle is tilted, and the welding dead angle area between the ladle main body and the ladle accessories is exposed, which is more conducive to the full welding of the ladle accessories and the ladle main body. After the ladle main body is tilted, as the rotating cylinder 8 rotates in the fixed drum 3, the ladle main body can continue to rotate along the center point of the fixed drum 3, which is convenient for the processing personnel to fully perform welding operations between multiple ladle accessories and the ladle main body itself.

[0049] like Figures 1 to 2 and Figures 7 to 9As shown, the discharge chute frame 7 is slidably connected to one side of the top of the mounting frame 2, and the discharge chute frame 7 moves synchronously with the lifting chute frame 6. A plurality of auxiliary fixing structures are provided on the discharge chute frame 7. The auxiliary fixing structure is used to drive the ladle accessories to move laterally in the direction of the ladle main body. When the lifting chute frame 6 is located in the center position of the mounting frame 2, the ladle main body also remains vertical. At this time, the discharge chute frame 7 also remains vertical, and the ladle accessories fixed on the discharge chute frame 7 correspond to the actual welding positions on the ladle main body. When the ladle main body is allowed to deviate, the discharge chute frame 7 will move with the sliding seat 22, so that the discharge chute frame 7 always corresponds to the center line position of the ladle main body, and then the ladle accessories fixed on the discharge chute frame 7 always correspond to the welding positions on the ladle main body.

[0050] Both sides of the discharge chute frame 7 are fixedly connected with a plurality of slots 25, and the plurality of slots 25 are evenly arranged on the inner wall of the discharge chute frame 7. The auxiliary fixing structure is arranged between the corresponding two slots 25 through the mounting structure. The mounting structure includes a sliding mounting member 26 and an inserting plate 29. Both sides of the sliding mounting member 26 are provided with sliding protrusions 27. An insertion port 28 is opened in the middle of the sliding mounting member 26. An inserting plate 29 is slidably connected to the two sliding protrusions 27. The inserting plate 29 extends into the slot 25. In order to fix the ladle accessories at different positions on the discharge chute frame 7, the inserting plate 29 can be inserted into the corresponding slot 25 on the discharge chute frame 7 by sliding the inserting plate 29 on the sliding protrusion 27, so as to fix the sliding mounting member 26 at the corresponding position in the discharge chute frame 7;

[0051] The auxiliary part fixing structure includes a discharge chute body 30 and an auxiliary part fastening assembly. The bottom of the discharge chute body 30 is laterally slidably connected to a fixing seat 31, which extends into the insertion port 28. The auxiliary part fastening assembly is slidably arranged in the discharge chute body 30, and is used to fasten the outer wall of the ladle auxiliary part, fix the ladle auxiliary part at a specified position in the discharge chute body 30, so that the end face of the ladle auxiliary part close to the ladle body is exposed from the discharge chute body 30, and the end face of the ladle auxiliary part can be brought into contact with the corresponding part of the ladle body. By extending the fixing seat 31 into the insertion port 28, the discharge chute body 30 is fixed to the top of the sliding mounting member 26, and then the discharge chute body 30 is pushed to move on the upper side of the fixing seat 31, so that the ladle auxiliary part is brought into contact with the ladle body.

[0052] The auxiliary fastening assembly includes a sliding plate body 32 and a fastening wire 35. The number of sliding plate bodies 32 is set to two. A screw distance adjusting member is provided between the two sliding plate bodies 32. The screw distance adjusting member includes an adjusting screw 42 and an adjusting nut. An adjusting screw 42 is rotatably connected to one sliding plate body 32, and an adjusting nut is connected through the other sliding plate body 32. The adjusting screw 42 and the adjusting nut are threadedly connected. Thread grooves 33 are provided on both sides of the top of the sliding plate body 32. The thread groove 33 is internally threadedly connected to a rotating seat 34. A threaded column is provided at the bottom of the rotating seat 34. The threaded column is threadedly connected to the thread groove 33. A through hole is opened on the rotating seat 34. The fastening wire 35 passes through the corresponding two through holes. The fastening wire 35 fits with the outer wall of the ladle auxiliary part, and then the ladle auxiliary part is placed in the discharge trough body 30. According to the shape and placement position of the ladle auxiliary part, the adjustment screw 42 and the adjustment screw 42 are used to adjust the distance between the two sliding plates 32. Then the ladle auxiliary part is placed between the two sliding plates 32. After the ladle auxiliary part is fastened with the fastening wire 35, the fastening wire 35 passes through the two through holes. By rotating the rotating seat 34, the fastening wire 35 begins to bend following the flipping of the through hole angle. The fastening wire 35 fastens the ladle auxiliary part at this time, and during the rotation of the rotating seat 34, the threaded column is spirally extended into the threaded groove 33 to keep the rotating seat 34 fixed.

[0053] Working principle of the welding equipment for welding and installing ladle accessories:

[0054] First, use the hoisting equipment to hoist the ladle body that needs to be welded with the auxiliary parts and the main body, and move it toward the top of the rotating cylinder 8. When the ladle body is moved toward the upper side of the bucket-shaped mounting cylinder 9, the inner bottom wall of the ladle body will directly contact the top of the bottom support plate 11. The ladle body will squeeze the bottom support plate 11 and move downward during the hoisting process. When the ladle body is driven downward, the top clamping body 12 clamps the ladle body, and then the pushing screw is rotated to drive the sliding trough 19 and the clamping seat 20 to descend together. The sliding trough 19 descends along the inclination angle of the sliding trough frame, so that the clamping seat 20 gradually contacts the corresponding position of the ladle body, and then the ladle body is clamped;

[0055] Then, a corresponding number of sliding mounting members 26 are fixed to the discharge chute frame 7, and the auxiliary fastening assembly is used to fix the ladle auxiliary member to the discharge chute body 30, and the fixing seat 31 is extended into the insertion port 28, and the discharge chute body 30 is fixed on the top of the sliding mounting member 26, and then the discharge chute body 30 is pushed to move on the upper side of the fixing seat 31, so that the ladle auxiliary member is in contact with the ladle main body, and then the welding equipment 1 is used to weld the ladle auxiliary member and the ladle main body. It should be noted that in order to improve the participation of the use of multiple welding equipment 1, the welding equipment 1 closest to the discharge chute frame 7 will only weld multiple stable welding points when welding between the ladle auxiliary member and the ladle main body, and then the rotating cylinder 8 will drive the ladle main body to rotate, so that the next ladle auxiliary member is welded to the ladle main body, and for a thorough welding operation, other welding equipment 1 will be used;

[0056] By driving the sliding seat 22 to move horizontally, the ladle body will be offset along the center point of the rotating shaft seat 4, and the position of the discharge chute frame 7 will always correspond to the center line position of the ladle body, so that the ladle accessories and the ladle body can correspond to each other.

[0057] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present invention may be modified or replaced by equivalents without departing from the spirit and scope of the technical solutions of the present invention, which should all be included in the scope of the claims of the present invention.
