[0048] This embodiment relates to a rotary welding device that is convenient for welding. In terms of overall structure, Figure 1 As shown, it includes a workbench 1, a chuck 2, a cylinder 3, a supporting wheel 4, and a welding gun 5.

[0049] Among them, the chuck 2 is rotatably set on the workbench 1, one end of the cylinder 3 is clamped on the chuck 2 and rotates with the chuck 2, the support wheel 4 is rotatably set on the workbench 1, the cylinder 3 is placed on the support wheel 4, the auxiliary cylinder 3 rotates, and the welding gun 5 is located on one side of the workbench 1. When the cylinder 3 rotates, the welding gun 5 welds and slides back and forth along the central axis direction of the cylinder 3. A linear guide rail 7 is provided on one side of the length direction of the workbench 1, and the welding gun 5 slides following the linear guide rail 7.

[0050] It is worth mentioning that the cylinder 3 rotates with the chuck 2 to ensure that the welding gun 5 can weld any position of the circular surface of the cylinder 3. The support wheel 4 is used to place the cylinder 3 to ensure that the cylinder 3 can remain parallel to avoid changes in the position of the cylinder 3 during welding, thereby affecting the welding quality. The linear guide rail 7 is a common sliding mechanism in the prior art and will not be described here. The welding gun 5 can choose a robotic arm type welding gun 5. The robotic arm is installed at the moving end of the linear guide rail 7 to ensure that any position in the length direction of the cylinder 3 can be welded. The coordinated setting of the chuck 2 and the linear guide rail 7 can ensure that any position of the cylinder 3 can be welded.

[0051] Based on the overall introduction above, an exemplary structure of the rotary welding device for convenient welding of this embodiment is as follows: Figure 1 and Figure 2 As shown, the workbench 1 is provided with an auxiliary member 8 for mounting the support wheels 4. The workbench 1 is also provided with a driving member 6 for rotating the chuck 2. Specifically, the auxiliary member 8 and the support wheels 4 are arranged in multiple groups along the central axis of the cylinder 3 to ensure the balance of the cylinder 3. The driving member 6 can drive the chuck 2 to rotate, ensuring that the cylinder 3 rotates at a uniform speed.

[0052] As a preferred embodiment, Figure 2 As shown, in this embodiment, the auxiliary component 8 includes a support block 801 fixedly mounted on the workbench 1, a roller shaft 802 mounted on the support block 801 for mounting the support wheel 4, two support wheels 4 disposed opposite each other on the roller shaft 802, and the two support wheels 4 abut against the cylinder 3. It should be noted that the two support blocks 801 are disposed opposite each other and arranged radially along the cylinder 3, with the ends of the roller shaft 802 mounted on the two support blocks 801 respectively. The support wheel 4 can be slidably mounted on the roller shaft 802 via a bearing, so that when the cylinder 3 moves, the support wheel 4 can rotate accordingly.

[0053] As a preferred Figure 3As shown, the support block 801 of this embodiment is provided with a groove 804 for placing the roller shaft 802. Nuts 805 are screwed onto both ends of the roller shaft 802. The two nuts 805 fix the roller shaft 802 to the support block 801. A tension spring 803 is provided between the two support wheels 4. After the cylinder 3 is placed on the support wheels 4, the support wheels 4 are pushed to slide to both sides. Specifically, the purpose of providing the groove 804 is to facilitate the disassembly and assembly of the roller shaft 802. The nut 805 and the support block 801 abut against each other, which can fix the roller shaft 802 to the support block 801. The provision of the tension spring 803 can ensure that the two support wheels 4 are close to each other. When the cylinder 3 is pressed down on the support wheels 4, it can ensure that the support wheels 4 slide to both sides, ensuring that the support wheels 4 can accommodate cylinders 3 of different sizes.

[0054] As a preferred embodiment, Figure 4 As shown, in this embodiment, the driving member 6 includes a vertical plate 601 fixed to the workbench 1, a motor 602 for driving the rotation of the chuck 2, and a driven member 603 connecting the motor 602 and the chuck 2. The chuck 2 is rotatably connected to the vertical plate 601. It should be noted that two vertical plates 601 are vertically mounted on the workbench 1 to ensure the stability of the rotation of the chuck 2. The motor 602 is located at the bottom of the workbench 1. The rotation of the motor 602 drives the driven member 603, which in turn drives the rotation of the chuck 2, thereby improving the stability of the rotation of the chuck 2.

[0055] As a preferred Figure 5 As shown, the driven member 603 of this embodiment includes a large bevel gear 6031 fixedly mounted on the chuck 2, a transmission rod 6032 fixedly mounted on the drive shaft of the motor 602, and a small bevel gear 6033 fixedly mounted on the transmission rod 6032 and meshing with the large bevel gear 6031. The transmission rod 6032 passes through the workbench 1 and is connected to the workbench 1 with a bearing. Specifically, the large bevel gear 6031 is sleeved on the chuck 2, the motor 602 drives the transmission rod 6032 to rotate, and the small bevel gear 6033 rotates along with the transmission rod 6032, thereby achieving the large bevel gear 6031 driving the chuck 2 to rotate. The workbench 1 has a through hole, a bearing is installed in the through hole, and the transmission rod 6032 is inserted into the bearing to ensure the stability of the rotating rod during rotation.

[0056] As a preferred Figure 6As shown, the transmission rod 6032 of this embodiment is provided with an adjustment hole 6034 for sliding the small bevel gear 6033. The small bevel gear 6033 is fixedly provided with a fixing rod 6037 that slides in the adjustment hole 6034. Connecting plates 607 are provided on both sides of the top of the transmission rod 6032. Bolts 608 that abut against the fixing rod 6037 are screwed onto the connecting plates 607. Specifically, the fixing rod 6037 is raised and lowered and slid in the adjustment hole 6034 to achieve engagement and disengagement between the large bevel gear 6031 and the small bevel gear 6033. The bolt 608 can be threadedly rotated on the connecting plate 607 to lock the fixing rod 6037 in the adjusted position, ensuring that the adjusting rod can be fixed after the raising and lowering is completed.

[0057] As a preferred embodiment, Figure 6 As shown, in this embodiment, a keyway 6035 and a key block 6036 are respectively provided on the adjustment hole 6034 and the fixing rod 6037. Specifically, the engagement of the keyway 6035 and the key block 6036 ensures that the fixing rod 6037 rotates along with the transmission rod 6032, and the bolt 608 abuts against the fixing rod 6037, thereby fixing the fixing rod 6037.

[0058] As a preferred Figure 4 and Figure 6 As shown, the outer cover of the vertical plate 601 of this embodiment is provided with a shell 604, and a circular shaft 605 is passed through the shell 604. The end of the circular shaft 605 is also provided with a small bevel gear 6033, which is engaged with the large bevel gear 6031. The end of the circular shaft 605 extending from the shell 604 is provided with a handwheel 606. Specifically, when the small bevel gear 6033 and the large bevel gear 6031 on the fixed rod 6037 are separated, the small bevel gear 6033 on the circular shaft 605 can be rotated by rotating the handle, thereby manually controlling the rotation of the cylinder 3 and ensuring more precise welding. The circular shaft 605 can rotate on the shell 604 and can also slide on the shell 604, thereby ensuring that the handwheel 606 does not rotate with the rotation of the motor 602, and the motor 602 does not rotate with the rotation of the handwheel 606.

[0059] The rotary welding equipment for convenient welding in this embodiment reduces the complexity and cost of the equipment by simplifying the workpiece positioning and clamping device during the circumferential welding process; improves the welding quality by improving the stability of the rotation of the cylinder 3; improves the smoothness of the rotation of the cylinder 3 by ensuring the close contact between the support wheel 4 and the cylinder 3, thereby improving the welding efficiency; and increases the flexibility of the equipment by providing the function of manually adjusting the rotation speed of the chuck 2.

[0060] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
