Description

Technical Field

[0001] This application relates to the technical field of welding devices, and particularly to an automatic bottom ring welding device. Background Art

[0002] Generally, a bottom ring is welded to the bottom of a stainless steel barrel to prevent the barrel from being damaged by the outside during transportation. Since most of the lower end covers of the barrel adopt a curved surface structure (such as a head), the lower end cover cannot be placed upright normally. This requires adding a structure at the bottom of the barrel that can make the barrel placed stably, such as a bottom ring.

[0003] To prevent the appearance of welding discoloration on the inner surface of the barrel after welding, coolant is filled inside the barrel to be welded before welding, and then the bottom ring is welded. During this process, in order to maintain the stability of the coolant inside the workpiece, the workpiece cannot be skewed, and the position of the workpiece needs to be maintained, resulting in inconvenience in welding the bottom ring and low welding efficiency.

[0028] An automatic bottom ring welding device includes a first transmission component 1, a second transmission component 2, a manipulator 3, a welding robot 4, and a welding seat 5.

[0029] The transmission directions of the first transmission component 1 and the second transmission component 2 are the same (transmitting workpieces from front to back, the feeding end is the front side, and the discharging end is the rear side). The first transmission component 1 and the second transmission component 2 are arranged at intervals along the transmission direction. The first transmission component 1 is the feeding line, and the second transmission component 2 is the discharging line. The manipulator 3 is arranged between the first transmission component 1 and the second transmission component 2, and the manipulator 3 is located between the discharging end of the first transmission component 1 and the feeding end of the second transmission component 2.

[0030] Further, the first transmission component 1 includes a first transmission frame 11 and a first transmission belt 12. Two transmission rollers are rotatably arranged on the first transmission frame 11, and the first transmission belt 12 is sleeved on the two transmission rollers. A driving source 13 for driving the transmission rollers to rotate is arranged on the first transmission frame 11. A water injection pipe 7 is connected to the first transmission frame 11, and the nozzle of the water injection pipe 7 faces the workpiece placed on the first transmission belt 12. The water injection pipe 7 injects water into the workpiece. The position on the first transmission frame 11 below the water injection pipe 7 is the water injection level. In this embodiment, the workpiece is a cylindrical workpiece, and its opening is placed vertically upward on the first transmission belt 12. It should be noted that the driving source 13 in the first transmission component 1 adopts a stepping motor, so that after the workpiece moves to the water injection level, the workpiece stays below the water injection pipe 7 to hold water.

[0031] The second transmission component 2 includes a second transmission frame 21 and a second transmission belt 22. Two transmission rollers are also rotatably arranged on the second transmission frame 21, and the second transmission belt 22 is sleeved on the two transmission rollers. A driving source 13 for driving the transmission rollers to rotate is arranged on the second transmission frame 21.

[0032] The welding seat 5 is arranged on one side of the first transmission frame 11 and is close to the second transmission frame 21. A receiving table 51 is rotatably connected to the welding seat 5. A receiving cavity for installing a driving motor is arranged in the welding seat 5. The driving motor is used to drive the receiving table 51 to rotate at a constant speed. A clamping member is coaxially connected to the receiving table 51. The clamping member can be a pneumatic chuck 52. The welding robot 4 is arranged on one side of the manipulator 3 and is on the same side of the first transmission component 1 as the welding seat 5.

[0033] Preferably, the welding robot 4 is arranged on the front side of the welding seat 5, and the manipulator 3 is arranged on the rear side of the first transmission frame 1 and the welding seat 5. Thus, when the manipulator 3 grabs the workpiece and moves it onto the welding seat 5, and then moves the workpiece on the welding seat 5 onto the second transmission frame 21, the welding robot 4 will not interfere with the movement line of the manipulator.

[0034] A collection tank 6 is arranged on one side of the manipulator 3. The collection tank 6 is used to receive the cooling water in the workpiece after welding is completed. The water injection level, the welding seat 5, and the collection tank 6 can be circumferentially arranged on the same side of the manipulator 3 with the base of the manipulator 3 as the center, so as to further save the movement path of the manipulator 3.

[0035] Further, both sides of the first transmission belt 12 are spaced from the first transmission frame 11. An overflow tank is connected to the first transmission frame 11. The overflow tank is located between the top surface and the bottom surface of the first transmission belt 12. The cooling water overflowing from the workpiece welding position flows into the overflow tank, which is convenient for recycling and reuse.

[0036] Place the grouped workpieces on the loading line. Through the transfer of the first conveyor belt 12, transfer the workpieces to the lower part of the water injection pipe 7. The water injection pipe 7 fills the workpieces with cooling water. The cooling water is filled below the bottom ring of the workpiece to be welded and close to the welding position, so as to prevent the inner wall of the workpiece from generating abnormal colors due to excessive heat during the welding process. After water injection, the manipulator 3 places the workpiece on the receiving table 51, and the workpiece is fixed on the receiving table 51 pneumatically. Rotate the receiving table 51, and the welding robot 4 welds the welding position of the workpiece. After the workpiece is welded, the manipulator 3 transfers the workpiece above the collection tank 6, pours the cooling water into the collection tank, and then moves the workpiece to the unloading line.

[0037] Through the automated transmission mechanism of the present application, the transmission of the bottom ring is realized, and a rotating pneumatic chuck is used to fix the workpiece to achieve automated welding. During the welding process, the workpiece rotates stably without skewing, ensuring the stability of the batch welding quality; cooling water is injected into the workpiece during the transmission process to avoid the generation of abnormal colors inside the workpiece after welding, reducing the time for abnormal color polishing treatment.

[0038] The present application can achieve batch welding, reduce manual operation, greatly save time, and improve production efficiency; the cooling water can be recycled into the collection tank 6 to save resources.

[0039] Enlightened by the above ideal embodiments based on the present utility model, through the above description, relevant staff can completely make various changes and modifications without departing from the technical idea of this utility model. The technical scope of this utility model is not limited to the content in the specification, and its technical scope must be determined according to the scope of the claims.
