Description

Technical Field

[0001] This utility model relates to the technical field of cylindrical welding devices, specifically a vertical cylindrical welding device. Background Technology

[0002] During the manufacturing process, welding is required to connect two cylinders together. Due to the large diameter of the cylinders, they need to be stood upright during welding to ensure stability during the welding process.

[0003] Currently, when performing vertical welding on cylinders, one cylinder is installed at the bottom, and another cylinder is placed on top of the bottom cylinder. Then, the cylinders are rotated by a device, so that the welding head can weld the two cylinders at the welding positions. However, due to the large overall diameter of the cylinders, the rotation welding is not stable enough and is prone to tipping over. Therefore, it is necessary to improve the vertical welding device for cylinders to solve the above problems. Utility Model Content

[0006] The positioning mechanism includes a lifting component and a positioning component. The lifting component is located on the top of the base, and the positioning component is located outside the base and the lifting component.

[0007] The lifting assembly includes a support frame, which is fixedly installed on the top of the base. A first motor is fixedly installed on the top of the support frame, and a first screw is fixedly installed on the output end of the first motor. A lifting plate is slidably installed inside the support frame extending to the front, so as to facilitate the adjustment of the position of the lifting plate according to the height of the cylinder.

[0008] Preferably, the lifting plate has a threaded hole at the corresponding position of the first screw, and the first screw is threadedly installed in the threaded hole, so that the first screw can drive the lifting plate to move up and down.

[0009] Preferably, the positioning component includes a motor base, which is fixedly installed at the bottom of the base and the top of the lifting plate. A second motor is fixedly installed on the inner side of the motor base, and a central bevel gear is fixedly installed at the output end of the second motor. A sliding clamp is slidably installed from the inside to the outside of the base and the lifting plate. A support block and a fixing block are fixedly installed at the bottom of the base and the top of the lifting plate. A second screw is rotatably installed on the inner side of the support block, and a bevel gear is fixedly installed at the end of the second screw away from the support block, which facilitates positioning, clamping and fixing of the cylinder.

[0010] Preferably, the sliding clamp has a threaded hole at the corresponding position of the second screw, and the second screw is threadedly installed in the threaded hole. The end of the second screw away from the support block is rotatably installed inside the fixed block, so as to facilitate the second screw to drive the sliding clamp to slide.

[0011] Preferably, there are eight bevel gears, which are meshed in groups of four on the outside of the two central gear discs to facilitate synchronous rotation of the bevel gears.

[0012] Preferably, the welding mechanism includes an annular guide rail, which is fixedly installed on the top of the base. A sliding seat is slidably installed on the outside of the annular guide rail. A third motor is fixedly installed on the top of the sliding seat. A drive gear is fixedly installed on the output end of the third motor.

[0013] Preferably, a limiting groove is provided at the bottom of the sliding seat, and the sliding seat is slidably mounted on the outside of the annular guide rail through the limiting groove, so that the sliding seat can be limited and slid outside the annular guide rail.

[0014] Compared with the prior art, this utility model provides a vertical welding device for cylinders, which has the following advantages:

[0015] 1. This vertical cylindrical welding device, through its positioning mechanism, allows for the sequential stacking of two cylindrical bodies during use. The two bodies are clamped and positioned by a clamping plate, and the position of the clamping plate can be adjusted according to the diameter of the cylindrical body via a sliding adjustment structure. Simultaneously, the lifting assembly allows for the adjustment of the lifting plate position according to the length of the cylindrical body, thereby achieving precise positioning, clamping, and fixing of the cylindrical body and preventing tipping during welding.

[0016] 2. This vertical cylindrical welding device, through its welding mechanism, allows the sliding seat to rotate around the annular guide rail during use. This causes the welding head to rotate around the cylindrical body, enabling the welding head to perform annular welding on the cylindrical body. As a result, the cylindrical body does not need to move, ensuring stability during the welding process. Attached Figure Description
