Technical Field

[0001] The utility model relates to the technical field of cylinder welding, in particular to an auxiliary welding device for large aluminum alloy cylinders. Background Technique

[0002] Large aluminum alloy cylinders are cylindrical components made of aluminum alloy materials, with various application scenarios and advantages. Aluminum alloy, as a light metal material based on aluminum and added with other alloying elements, not only has the general properties of aluminum but also has specific alloy properties due to different types and amounts of added elements. Aluminum alloy cylinders are widely used in many industries due to their light weight, high strength, good workability, and corrosion resistance, such as aerospace, marine, chemical, and metal packaging industries. Large aluminum alloy cylinders usually have large sizes and volumes, which can meet specific industrial requirements.

[0003] Based on the above, the inventor found the following problems: During the production of large aluminum alloy cylinders, two sections of aluminum alloy cylinders need to be welded together. However, when welding the two sections of aluminum alloy cylinders, the user needs to continuously adjust the positions of the two sections of aluminum alloy cylinders to make their interfaces fit. At the same time, during the welding process, it is inconvenient to rotate the two sections of aluminum alloy cylinders, and it is necessary to manually hold the welding tool to surround the interfaces of the two sections of aluminum alloy cylinders to achieve welding, which is rather inconvenient.

[0004] Therefore, in view of this, research and improvement are carried out on the existing structure and deficiencies, and an auxiliary welding device for large aluminum alloy cylinders is provided, with the expectation of achieving a more practical value. Content of the Utility Model

[0005] The purpose of the utility model is to provide an auxiliary welding device for large aluminum alloy cylinders to solve the problems raised in the above background technique.

[0006] In view of the above problems, the technical solution proposed by the utility model is as follows:

[0007] An auxiliary welding device for a large aluminum alloy cylinder includes a support mechanism, an auxiliary mechanism and a driving mechanism. The support mechanism includes a support table, and a plurality of arc-shaped seats are connected to the upper end surface of the support table. The auxiliary mechanism includes a pair of mounting tables, and the pair of mounting tables are respectively arranged on both sides of the outer wall of the support table. And auxiliary plates are connected to the upper end surfaces of the pair of mounting seats. A transmission seat is rotatably connected inside the auxiliary plate. Both ends of the transmission seat respectively penetrate through the auxiliary plate, and one end of the transmission seat is connected to a first circular plate.

[0008] Further, an external gear disc is sleeved outside the transmission seat. A rotating shaft is rotatably connected inside the auxiliary plate below the external gear disc. A gear is sleeved outside the rotating shaft. The gear meshes with the external gear disc. One end of the rotating shaft penetrates through the auxiliary plate and extends to the outside.

[0009] The beneficial effect of adopting the above further scheme is that through the cooperation of the external gear disc and the gear, when the rotating shaft rotates, it is convenient to realize the rotation of the gear, and then the rotation of the external gear disc drives the transmission seat to rotate.

[0010] Further, the driving mechanism includes a bracket. The bracket is arranged on one side of the upper ends of the pair of mounting tables. A rotating rod is rotatably connected inside the bracket. Synchronous wheels are sleeved outside both ends of the rotating rod and one end of the rotating shaft. A synchronous belt is wound between the pair of synchronous wheels on the same side.

[0011] The beneficial effect of adopting the above further scheme is that by arranging the rotating rod, when the rotating rod rotates, the synchronous wheels sleeved at both ends thereof rotate. Thus, under the transmission action of the synchronous belt and the synchronous wheels, the rotating shafts corresponding to both ends of the rotating rod rotate.

[0012] Further, a motor is connected to one side of the outer wall of the bracket. The output end of the motor is in transmission connection with the rotating rod.

A square seat is connected to the center of the fixing seat. A plurality of automatic telescopic rods are embedded inside the square seat. The movable ends of the plurality of automatic telescopic rods are all connected to pressing blocks.

[0015] The beneficial effect of adopting the above further solution is that by setting the fixed seat, since the fixed seat is connected to the second circular plate, when the opposite ends of a pair of aluminum alloy cylinder parts are in contact, the side of the second circular plate connected with the fixed seat is in contact with the opposite ends of the pair of aluminum alloy cylinder parts, so that the fixed seat enters the inside of the cylinder part. By starting the automatic telescopic rod, the pressing block can be pushed.

[0016] Further, a plurality of square grooves are formed on the outer side of the fixed seat, the plurality of pressing blocks and the plurality of square grooves are distributed in an equidistant annular shape, and the plurality of pressing blocks are respectively in clearance fit with the plurality of square grooves.

[0017] The beneficial effect of adopting the above further solution is that by setting the square groove and the square groove is in clearance fit with the pressing block, it is convenient for the pressing block to extend out of the inside of the fixed seat through the square groove.

[0018] Further, the welding mechanism includes an electric slide rail, the back surface of the electric slide rail is connected to the front surface of the support table, and an electric slide block is slidably connected to the outside of the electric slide rail. A support plate is connected to the front surface of the electric slide block. The support plate is in an "L" shape, and a cylinder is connected to the front surface of the support plate. The movable end of the cylinder penetrates through the support plate and is connected to a welding torch.

[0019] The beneficial effect of adopting the above further solution is that by the combined use of the electric slide rail and the electric slide block, when the electric slide block moves on the electric slide rail, it drives the support plate, the welding torch and the cylinder to perform horizontal adjustment to adjust the welding point. By setting the cylinder, when the cylinder works, it can push the welding torch close to the joint of a pair of cylinder parts, and then use the welding torch to complete the welding work.

[0020] Compared with the prior art, the beneficial effect of the present utility model is that for the auxiliary welding device for large aluminum alloy cylinder parts, through the combined use of the support table and the arc seat, it is convenient to place a pair of aluminum alloy cylinder parts to be welded on the arc seat, support the aluminum alloy cylinder parts and prevent the aluminum alloy cylinder parts from displacing under the action of the arc seat. Then, by setting the hydraulic cylinders, the number of the hydraulic cylinders and the auxiliary plates is two. When a pair of hydraulic cylinders work, it is convenient to push the second circular plate connected to their movable ends to move towards the center, so that a pair of aluminum alloy cylinder parts on the arc seat are completely in contact. When the opposite ends of a pair of aluminum alloy cylinder parts are in contact, the side of the second circular plate connected with the fixed seat is in contact with the opposite ends of the pair of aluminum alloy cylinder parts, so that the fixing mechanism enters the inside of the cylinder part to fix the cylinder part. When the rotating shafts inside a pair of auxiliary plates rotate, the gears will rotate, and then the external gear disc will rotate to drive the transmission seat to rotate, so that the first circular plate, the second circular plate, the hydraulic cylinders and the fixing mechanism rotate, thus realizing the rotation of a pair of completely contacted aluminum alloy cylinder parts, and cooperating with the auxiliary welding mechanism to complete the welding work of a pair of aluminum alloy cylinder parts.
