Description

Technical Field

[0001] The present invention relates to the technical field of welding devices, in particular to a welding device with high safety performance for manufacturing mining machinery and equipment. Background Art

[0002] Welding equipment for the manufacture of mining machinery and equipment is a special equipment designed for the welding needs of heavy components of mining machinery. It has high-intensity welding output and precise operation performance. Its core welding mechanism adopts a high-power inverter power supply and supports multiple processes such as arc welding and submerged arc welding. It can stably weld thick steel plates, steel castings and other core components of mining machinery to ensure that the weld penetration meets the standards and the strength is reliable. The device is equipped with an adjustable welding robot arm and combined with a rotating worktable to achieve multi-directional welding, which is suitable for complex welds of frames, rollers and other components of different specifications.

[0003] Therefore, based on the actual use of the existing welding device for the manufacture of mining machinery and equipment, since it is aimed at mining machinery, mining machinery is usually a thick welded component. It is difficult to effectively and accurately fix the welded component before welding the thick welded component. At that time, in the process of fixing the welded component, the adaptability of traditional tooling and fixtures was poor, and it was difficult to firmly clamp the large and special-shaped components of the mining machinery. During welding, displacement was easily caused by vibration, resulting in weld offset and poor fusion. The manual fastening method was inefficient, and the uneven clamping force would cause micro-deformation of the workpiece, affecting the subsequent assembly accuracy. In addition, the fixing equipment lacked buffer protection, and hard contact clamping could easily damage the surface of the component, especially causing scratches on workpieces made of special materials such as wear-resistant steel. The adjustment range of some fixtures was limited, and the frames, buckets and other components of different specifications needed to be frequently replaced, which increased the auxiliary time.

DETAILED DESCRIPTION

[0027] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings.

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.

[0028] As introduced in the background technology, in order to solve the deficiencies in the prior art and the above technical problems, the present application proposes a welding device for manufacturing mining machinery and equipment with high safety performance.

[0029] In a typical embodiment of the present application, Figure 1-7 As shown, a welding device for manufacturing mining machinery and equipment with high safety performance includes:

[0030] Welding table 1, the top of the welding table 1 is slidingly connected to the welding robot 2, a motor 3 is fixedly installed on one side of the welding table 1, the output end of the motor 3 is fixedly connected to the threaded rod 4, the threaded rod 4 is screwed on the bottom of the welding robot 2, and the threaded rod 4 is rotatably connected to the top of the welding table 1. When it is necessary to weld mining machinery and equipment, the mining machinery and equipment are placed on the top of the welding table 1 and the welding robot 2 is used to weld the mining machinery welded parts. When the welding robot 2 cannot weld due to length restrictions, the motor 3 is started at this time, and the output end of the motor 3 rotates to drive the threaded rod 4 to rotate on the top of the welding table 1. The rotation of the threaded rod 4 drives the moving welding robot 2 to slide on the top of the welding table 1, which is convenient for welding mining machinery welded parts.

[0031] A vacuum machine 5 is fixedly installed at the bottom of the welding table 1, and a vacuum shell 6 is fixedly connected to the interior of the welding table 1. The output end of the vacuum machine 5 is connected to the interior of the vacuum shell 6. By starting the vacuum machine 5, the interior of the vacuum shell 6 is in a vacuum state;

[0032] The adsorption mechanism 7 is used to fix the welding parts of mining machinery. The adsorption mechanism 7 includes several first adsorption tubes 9 connected to the top of the vacuum shell 6. The several first adsorption tubes 9 all extend to the top of the welding table 1. The top of the first adsorption tube 9 is slidably connected to the second adsorption tube 10. The top of the second adsorption tube 10 is adapted to the welding part. The inside of the first adsorption tube 9 is fixedly connected to the first fixing frame 12. The top of the first fixing frame 12 is fixedly connected to the adsorption spring 14. The inside of the second adsorption tube 10 is fixedly connected to the second fixing frame 13. The top of the adsorption spring 14 is fixedly connected to the bottom of the second fixing frame 13.

[0033] By setting the above-mentioned structure, mining machinery welded parts of different shapes can be adsorbed and fixed. Specifically, the bottom of the mining machinery welded parts is not flat. When the mining machinery welded parts are placed on the top of the welding table 1, the protruding surface of the bottom of the mining machinery welded parts presses the second adsorption tube 10, causing the second adsorption tube 10 to slide inside the first adsorption tube 9, and the adsorption spring 14 is compressed. At this time, the vacuum machine 5 is started to evacuate the interior of the vacuum shell 6, and the mining machinery welded parts are vacuum adsorbed and fixed on the top of the welding table 1 through the first adsorption tube 9 and the second adsorption tube 10. It is worth mentioning that the adsorption spring 14 can provide a certain support effect on the mining machinery welded parts, thereby improving the welding accuracy of the mining machinery welded parts.

[0034] A rotating groove 17 is formed at the top of the second adsorption tube 10. A rotating ball 18 is rotatably connected to the interior of the rotating groove 17. The bottom of the rotating ball 18 is fixedly connected to a ventilation frame 35. A return spring 19 is fixedly connected to the top of the second fixing frame 13. The top of the return spring 19 is fixedly connected to the bottom of the ventilation frame 35.

[0035] The interior of the ventilation frame 35 is fixedly connected to an adsorption shell 36, the bottom of the inner wall of the adsorption shell 36 is fixedly connected to a retaining spring 39, the top of the retaining spring 39 is fixedly connected to a stopper 38, the stopper 38 is slidably connected to the inside of the adsorption shell 36, the bottom of the inner wall of the adsorption shell 36 is fixedly connected to a telescopic rod 40, the telescopic end of the telescopic rod 40 is fixedly connected to the bottom of the stopper 38, an adsorption hole 37 is opened on the outside of the adsorption shell 36, the adsorption hole 37 is adapted to the stopper 38, the top of the rotating ball 18 is fixedly connected to the rubber suction head 11, the top of the stopper 38 is fixedly connected to the starting needle 41, the top of the starting needle 41 and the rubber suction head 11 are both adapted to the welding parts.

[0036] By setting the above structure, the mining machinery welding parts at any angle on the bottom can be adsorbed and fixed, and the adsorption and fixing effect of the mining machinery welding parts can be improved. Specifically, in the process of placing the mining machinery welding parts on the top of the welding table 1, the top of the starting needle 41 first contacts the bottom of the mining machinery welding parts, and drives the starting needle 41 to move. The movement of the starting needle 41 drives the stopper 38 to slide inside the adsorption shell 36 and separate from the adsorption hole 37. At this time, the telescopic rod 40 is extended and the retaining spring 39 is compressed to start the adsorption mechanism 7, so that it can subsequently adsorb the mining machinery welding parts. At the same time, the top of the rubber suction head 11 is against the bottom of the mining machinery welding parts, and through The movement of the mining machinery welded parts drives the second adsorption tube 10 to slide inside the first adsorption tube 9, and drives the rotating ball 18 to rotate inside the rotating groove 17 according to the inclined surface of the mining machinery welded parts, so that the top of the rubber suction head 11 fits with the inclined surface of the mining machinery welded parts, thereby improving the adsorption effect. At this time, the vacuum machine 5 can be started to adsorb the mining machinery welded parts, and the top of the starting pin 41 on the adsorption mechanism 7 that does not touch the mining machinery welded parts does not contact the mining machinery welded parts, so that the adsorption hole 37 on it cooperates with the stopper 38, thereby avoiding the vacuum pressure inside the vacuum shell 6 from floating due to the unused adsorption mechanism 7, thereby improving the adsorption and fixing effect of the mining machinery welded parts.

[0037] The buffer fixing mechanism 8 is used to buffer and fix the height of the adsorption mechanism 7 and indirectly fix the welded parts. The buffer fixing mechanism 8 includes a plurality of buffer fixing shells 24 fixedly connected to the top of the inner wall of the vacuum shell 6. The top of the inner wall of the buffer fixing shell 24 is fixedly connected to the airbag 26. The bottom of the airbag 26 is fixedly connected to the first card 28. The interior of the buffer fixing shell 24 is rotatably connected to the driving rod 30. The top of the driving rod 30 is fixedly connected to the second card 31. The second card 31 is adapted to the first card 28.

[0038] The bottom of the second adsorption tube 10 is fixedly connected to a rifle rod 15, and the bottom of the first adsorption tube 9 is rotatably connected to a rifle sleeve 16. The rifle rod 15 is adapted to the rifle sleeve 16, and the rifle sleeve 16 is rotatably connected to the bottom of the first fixing frame 12. The rifle rod 15 slides inside the first fixing frame 12, and the top of the rifle rod 15 is fixedly connected to the bottom of the second fixing frame 13. The top of the rifle sleeve 16 is fixedly connected to a first limiting ring 20. A first limiting groove 21 is provided at the bottom of the first fixing frame 12. The rifle sleeve 16 rotates inside the first limiting groove 21 through the first limiting ring 20 to rotate at the bottom of the first fixing frame 12, and the rifle sleeve 16 rotates synchronously with the driving rod 30;

[0039] By setting up the above-mentioned structure, the positioning effect of the mining machinery welding parts can be improved based on the buffering positioning effect of the mining machinery welding parts in the process of placing the mining machinery welding parts on the top of the welding table 1 for positioning. At the same time, the second adsorption tube 10 can be fixed inside the first adsorption tube 9 to improve the adsorption stability of the mining machinery welding parts. Specifically, before placing the mining machinery welding parts on the top of the welding table 1, the vacuum machine 5 can be started first. The vacuum machine 5 can be adjusted in multiple gears. The vacuum machine 5 is the existing technology and will not be described in detail here. The vacuum machine 5 is adjusted to a low gear. At this time, the inside of the vacuum shell 6 is in a weak vacuum state, and the air bag 26 is driven to expand, the vacuum spring 27 is stretched, and the bottom of the first card cake 28 is slightly abutted against the top of the second card cake 31. At this time, the mining machinery welding parts can be placed on the top of the welding table 1, and the bottom of the mining machinery welding parts is abutted against the top of the rubber suction head 11, and the rubber suction head is driven to The head 11 moves downward, and at this time the rubber suction head 11 moves downward, driving the second adsorption tube 10 to move downward, and the second adsorption tube 10 moves downward, driving the rifle rod 15 to move downward, and the rifle rod 15 moves downward, driving the rifle sleeve 16 to rotate. Since the rifle sleeve 16 rotates synchronously with the driving rod 30, and at the same time, the bottom of the first card cake 28 lightly abuts the top of the second card cake 31, so that the rifle sleeve 16 rotates on the outside of the rifle rod 15, providing support for the welding parts of the mining machinery, facilitating the precise adjustment of the position and angle of the welding parts of the mining machinery. When the second adsorption tube 10 needs to be fixed inside the first adsorption tube 9, the vacuum machine 5 is adjusted to a high position at this time, so that the bottom of the first card cake 28 abuts the top of the second card cake 31, which improves the adsorption effect of the welding parts of the mining machinery and can fix the rotation of the driving rod 30, so that the rifle sleeve 16 fixes the second adsorption tube 10 indirectly to the inside of the first adsorption tube 9.

[0040] The buffer fixing mechanism 8 also includes a drive ring 29 rotatably connected to the interior of the buffer fixing shell 24. The exterior of the drive rod 30 is fixedly connected to the interior of the drive ring 29. A second limiting ring 33 is fixedly connected to the exterior of the drive ring 29. A second limiting groove 34 is defined within the buffer fixing shell 24. The second limiting ring 33 is rotatably connected to the interior of the second limiting groove 34. A vacuum tension spring 27 is fixedly connected to the bottom of the inner wall of the airbag 26.

[0041] The outer fixed sleeve of the rifle sleeve 16 is connected to the first synchronous wheel 22, the outer fixed sleeve of the drive rod 30 is connected to the second synchronous wheel 32, the outer rotating sleeve of the second synchronous wheel 32 of the first synchronous wheel 22 is connected to the same synchronous belt 23, and an avoidance groove 25 is opened on one side of the buffer fixed shell 24, and the synchronous belt 23 rotates inside the avoidance groove 25.

[0042] Furthermore, in the above scheme, through the above-mentioned structure, the second adsorption tube 10 can be driven to be fixed inside the first adsorption tube 9. Specifically, when it is necessary to fix the first adsorption tube 9 inside the second adsorption tube 10 or adjust the resistance of the first adsorption tube 9 to sliding inside the second adsorption tube 10, the vacuum machine 5 is started at this time to make the interior of the vacuum shell 6 in a vacuum state, and drive the airbag 26 to expand, so that the bottom of the first card cake 28 abuts against the top of the second card cake 31. At this time, the driving rod 30 stops or damps the rotation inside the buffer fixed shell 24. The driving rod 30 stops or damps the rotation, driving the synchronous belt 23 to stop or damp the rotation. The synchronous belt 23 stops or damps the rotation when the dynamic synchronous belt 23 stops or damps the rotation, and drives the first synchronous wheel 22 to stop or damp the rotation. The first synchronous wheel 22 stops or damps the rotation, driving the rifle sleeve 16 to stop or damp the rotation outside the rifle rod 15, thereby fixing the first adsorption tube 9 inside the second adsorption tube 10 or adjusting the resistance of the first adsorption tube 9 to sliding inside the second adsorption tube 10.

[0043] Working principle of the present invention: When it is necessary to weld a mining machinery weldment, before placing the mining machinery weldment on the top of the welding table 1, the vacuum machine 5 can be started first. The vacuum machine 5 can be adjusted in multiple gears. The vacuum machine 5 is a prior art and will not be described in detail here. The vacuum machine 5 is adjusted to a low gear. At this time, the interior of the vacuum shell 6 is in a weak vacuum state, and the air bag 26 is driven to expand, and the vacuum tension spring 27 is stretched. The bottom of the first card cake 28 is slightly abutted against the top of the second card cake 31, so that the rifle sleeve 16 is damped and rotated on the outside of the rifle rod 15. At this time, the mining machinery weldment can be placed on the top of the welding table 1;

[0044] In the process of placing the mining machinery welding part on the top of the welding table 1, the top of the starting pin 41 first contacts the bottom of the mining machinery welding part and drives the starting pin 41 to move. The movement of the starting pin 41 drives the stopper 38 to slide inside the adsorption shell 36 and separate from the adsorption hole 37. At this time, the telescopic rod 40 is extended and retracted, and the retaining spring 39 is compressed to start the adsorption mechanism 7, so that it can subsequently adsorb the mining machinery welding part. At the same time, the top of the rubber suction head 11 is against the bottom of the mining machinery welding part, and the movement of the mining machinery welding part drives the second adsorption tube 10 to slide inside the first adsorption tube 9. The adsorption spring 14 is compressed and drives the rotating ball 18 to rotate inside the rotating groove 17 according to the inclined surface of the mining machinery welding part, so that the top of the rubber suction head 11 fits the inclined surface of the mining machinery welding part, thereby improving the adsorption effect and adsorbing the mining machinery welding part.

[0045] The top of the starting pin 41 of the adsorption mechanism 7 that is not in contact with the mining machinery welded part does not contact the mining machinery welded part, so that the adsorption hole 37 on it cooperates with the stopper 38, thereby preventing the vacuum pressure inside the vacuum shell 6 from fluctuating due to the unused adsorption mechanism 7, thereby improving the adsorption and fixing effect of the mining machinery welded part;

[0046] At the same time, when the mining machinery welding part is placed on the top of the welding table 1, the bottom of the mining machinery welding part abuts against the top of the rubber suction head 11, and drives the rubber suction head 11 to move downward. At this time, the downward movement of the rubber suction head 11 drives the second adsorption tube 10 to move downward, and the downward movement of the second adsorption tube 10 drives the rifle rod 15 to move downward. The downward movement of the rifle rod 15 drives the rifle sleeve 16 to rotate. Since the rifle sleeve 16 rotates synchronously with the driving rod 30, and at the same time, the bottom of the first card cake 28 lightly abuts against the top of the second card cake 31, the rifle sleeve 16 rotates on the outside of the rifle rod 15 with damping, providing support for the mining machinery welding part, and facilitating the precise adjustment of the position and angle of the mining machinery welding part;

[0047] When it is necessary to adjust the resistance of the first adsorption tube 9 to sliding inside the second adsorption tube 10, the vacuum machine 5 is started to put the interior of the vacuum shell 6 into a vacuum state, and the airbag 26 is driven to expand, so that the bottom of the first card cake 28 abuts against the top of the second card cake 31. At this time, the driving rod 30 rotates in a damped manner inside the buffer fixed shell 24. The damped rotation of the driving rod 30 drives the damped rotation of the synchronous belt 23. The damped rotation of the synchronous belt 23 drives the damped rotation of the synchronous belt 23 and drives the damped rotation of the first synchronous wheel 22. The damped rotation of the first synchronous wheel 22 drives the damped rotation of the rifle sleeve 16 on the outside of the rifle rod 15, thereby adjusting the resistance of the first adsorption tube 9 to sliding inside the second adsorption tube 10.

[0048] When it is necessary to fix the second adsorption tube 10 inside the first adsorption tube 9 and adsorb and fix the mining machinery welding parts, the vacuum machine 5 is adjusted to a high gear so that the bottom of the first clamping cake 28 is in contact with the top of the second clamping cake 31, thereby improving the adsorption effect of the mining machinery welding parts and fixing the driving rod 30 to rotate, so that the rifle sleeve 16 is fixed to indirectly fix the second adsorption tube 10 inside the first adsorption tube 9. At the same time, the high-gear vacuum machine 5 can further adsorb and fix the mining machinery welding parts.

[0049] While embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions, and variations may be made to these embodiments without departing from the principles and spirit of the invention, and that the scope of the invention is defined by the appended claims and their equivalents.
