Description

Technical Field

[0001] The utility model relates to the technical field of pressure vessel welding, in particular to a pressure vessel annular seam welding mechanism. Background Art

[0002] A pressure vessel is a closed container that can withstand pressure. It has a wide range of uses. It plays an important role in many sectors such as industry, civil industry, military industry, and many fields of scientific research. When manufacturing pressure vessels, it is necessary to weld the body and the cover. During the welding process, the two are in a sealed state. A pressure vessel welding device is required during the welding process.

The motor drives the driving gear to rotate, and the driving gear can drive the bottom plate to rotate in the storage groove through the driven gear, thereby completing the angle rotation when the body and the cover are welded.

[0004] The above technical scheme also has the following defects. Although the motor of the pressure vessel welding device drives the driving gear to rotate, the driving gear can drive the bottom plate to rotate in the storage groove through the driven gear, and then can complete the angle rotation when the body and the cover are welded, but in actual use, the device cannot stably clamp and fix the body. When the angle is rotated during welding, the body and the cover may be offset, which is not conducive to the stability of welding and affects the welding effect. Based on this, a pressure vessel circumferential seam welding mechanism is proposed to solve the above problems. Utility Model Content

[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0026] See also Figure 1-4 In order to ensure that the device body 8 can be clamped more stably, the fixing mechanism 4 in this embodiment includes a starting component, and the fixing mechanism 4 also includes an adjusting component. The adjusting component is provided with a fixing component, and the starting component includes a second motor 401 fixed to the inner bottom wall of the connecting box 3, and the output shaft of the second motor 401 is fixed with a third rotating rod 402 which is rotatably connected to the inner top wall of the connecting box 3 through a bearing, and the outer surface of the third rotating rod 402 is fixed with a third gear 403, and the third gear 403 is driven and rotated by the second motor 401, thereby providing power for the adjusting component.

[0027] Among them, the adjustment component includes four guide rods 404 fixed to the inner wall of the connecting box 3, and the outer surface of the guide rod 404 is slidably connected with a tooth plate 405. The adjustment component also includes four fixed seats 406 fixed to the inner bottom wall of the connecting box 3. The tooth plate 405 is meshed with the third gear 403, and one side of the fixed seat 406 is fixed to one end of the guide rod 404, so that the tooth plate 405 can move more stably. The fixing component includes an adjustment block 407 fixed to the upper surface of the tooth plate 405 and extending to the outside of the connecting box 3. Four moving holes are opened on the upper surface of the connecting box 3, and the moving holes and the adjustment block 407 are slidably connected. An adjusting rod 408 is fixed to the top of the adjustment block 407, and a clamping plate 409 is fixed to the side of the adjusting rod 408 close to the device body 8. The tooth plate 405 can drive the adjusting rod 408 and the clamping plate 409 to move, so as to fix the position of the device body 8.

[0028] At the same time, a friction pad is fixed to the side of the clamping plate 409 away from the adjusting rod 408, and the side of the friction pad away from the clamping plate 409 is in contact with the outer surface of the device body 8. The cross-section of the clamping plate 409 is arc-shaped, so that the clamping plate 409 can fit more completely with the device body 8 when fixing the device body 8, thereby further increasing the friction with the device body 8.

[0029] See also Figure 1In order to facilitate the adjustment of the welding angle, the rotating mechanism 2 includes a first motor 201 fixed to the inner bottom wall of the base plate 1, the output shaft of the first motor 201 is fixed with a first rotating rod 202 having one end rotatably connected to the inner top wall of the base plate 1 through a bearing, a first gear 203 is fixed to the outer surface of the first rotating rod 202, a second gear 204 is meshed on the left side of the outer surface of the first gear 203, a second rotating rod 205 is fixed to the inner wall of the axis of the second gear 204, the bottom of the second rotating rod 205 is rotatably connected to the inner bottom wall of the base plate 1, a rotating hole is opened on the upper surface of the base plate 1, the rotating hole is rotatably connected to the second rotating rod 205, the upper surface of the second rotating rod 205 is fixed to the lower surface of the connecting box 3, the second gear 204 and the second rotating rod 205 are driven to rotate by the first motor 201, and then the angle of the device body 8 and the device cover 9 is adjusted.

[0030] It should be noted that the starting component provides power to the adjusting component, and the adjusting component cooperates with the fixing component to stably clamp the device body 8, and at the same time cooperates with the rotating mechanism 2 to ensure the welding effect of the device body 8 and the device cover 9.

[0031] The working principle of the above embodiment is:

[0032] First, place the device body 8 at the designated position of the connection box 3, then start the second motor 401 to drive the third rotating rod 402 and the third gear 403 to rotate, so that the two sets of toothed plates 405 can be moved along the two sets of guide rods 404 respectively, and then the two sets of adjusting blocks 407 and adjusting rods 408 can be driven to move relative to each other, and the two sets of clamping plates 409 can be driven to move relative to each other until the two sets of clamping plates 409 fit with the outer surface of the device body 8, thereby stably fixing the device body 8. At the same time, due to the friction pads on the clamping plates 409, the clamping plates 409 can be further increased. The friction between the device body 8 can further stabilize the device body 8 at the specified position of the connecting box 3. Then, the device cover 9 is placed on the top of the device body 8 and aligned, and the cylinder 6 is started to drive the top plate 7 to push the device cover 9 against the top of the device body 8, so that the device cover 9 cannot shake on the top of the device body 8. Then, the first motor 201 is started to drive the first gear 203 and the first gear 203 to rotate, thereby driving the second gear 204 and the second rotating rod 205 to rotate, and then the connecting box 3 and the device body 8 can be driven to rotate, so as to complete the angle rotation when the device body 8 and the device cover 9 are welded.
