[0025] Please refer to Figure 1-Figure 6 The present invention provides a technical solution: a welding device for a hanging fire extinguisher bottle mouth seat, used for welding a bottle body part 81 and a bottle mouth part 82 constituting a fire extinguisher main body 8, comprising a base 1, a supporting mechanism 2 and a clamping mechanism 3 are provided on the top of the base 1, a column 4 is fixedly installed on the top of the base 1, a distance adjustment mechanism 5 is installed on the side of the column 4 close to the supporting mechanism 2, a variable diameter limit grinding assembly 6 is installed on the side of the distance adjustment mechanism 5 close to the supporting mechanism 2, a welding gun 7 is fixedly installed on the side of the column 4 close to the supporting mechanism 2, the variable diameter limit grinding assembly 6 is used for positioning and grinding fire extinguisher main bodies 8 of different diameters, the supporting mechanism 2 is used for supporting fire extinguisher main bodies 8 of different diameters to drive the fire extinguisher main body 8 to rotate, and the clamping mechanism 3 is used for clamping the fire extinguisher main body 8 in cooperation with the variable diameter limit grinding assembly 6.

[0026] The distance adjusting mechanism 5 includes a cylinder 51 fixedly connected to the column 4, a circular plate 52 is provided on the side of the cylinder 51 away from the column 4, a one-way bearing 57 is provided inside the cylinder 51, the one-way bearing 57 includes an inner ring and an outer ring, the outer ring of the one-way bearing 57 is fixedly connected to the inner wall of the cylinder 51, a connecting column 521 is fixedly installed on the side of the circular plate 52 close to the cylinder 51, and the connecting column 521 is fixedly connected to the inner ring of the one-way bearing 57.

[0027] A plurality of prisms 53 distributed in a circular array are slidably installed through the circular plate 52, a roller 54 is rotatably installed through one end of the prism 53 close to the cylinder 51, a connected annular groove 511 and a V-shaped slope groove 512 are provided on the side of the cylinder 51, and a plurality of rollers 54 are correspondingly installed in the annular groove 511 and the V-shaped slope groove 512 for rolling, a guide rail 55 is fixedly installed on one end of the prism 53 away from the roller 54, and a slider 56 is slidably installed on the guide rail 55.

[0028] The variable-diameter limiting grinding assembly 6 includes a circular plate 61, a rotating column 58 is rotatably installed at the center of the circular plate 61, a rotating ring 66 is rotatably installed on the side of the rotating column 58 away from the column 4, the rotating column 58 is fixedly connected to the side of the circular plate 52 away from the cylinder 51, and a plurality of adjustment holes 611 distributed in a circular array are opened on the circular plate 61, and circular shafts 62 are slidably installed through the plurality of adjustment holes 611, and the ends of the plurality of circular shafts 62 close to the column 4 are respectively fixedly connected to the corresponding sliders 56, and the ends of the circular shafts 62 away from the column 4 are fixedly installed with a grinding column 63.

[0029] Furthermore, through the guide rail 55 and the slider 56, the prism 53 can drive the circular shaft 62 to move synchronously, and the circular shaft 62 can slide on the guide rail 55 through the slider 56, so that the spacing between the multiple circular shafts 62 can be changed when the positions of the multiple prisms 53 remain unchanged.

[0030] A cutter 631 is fixedly mounted on one end of the grinding column 63 away from the circular shaft 62 .

[0031] An adjusting mechanism 64 connected to the circular plate 1 52 is provided on the circular plate 61. The adjusting mechanism 64 includes a mounting frame 641 fixedly connected to the side of the circular plate 1 52. The adjusting mechanism 64 also includes a gear ring 642 fixedly sleeved on the circular plate 61. A worm 643 is rotatably installed on the mounting frame 641, and a hand wheel 644 is fixedly installed on one end of the worm 643.

[0032] The supporting mechanism 2 includes four oil cylinders 21 fixedly mounted on the top of the base 1. The four oil cylinders 21 are distributed in a rectangular shape. The top ends of the piston rods of the four oil cylinders 21 are fixedly mounted with a same bottom plate 22. Two side plates 23 are fixedly mounted on the top of the bottom plate 22. Two power rollers 24 are rotatably mounted between the two side plates 23.

[0033] The clamping mechanism 3 includes two oil cylinders 31 fixedly mounted on the top of the base 1, the top ends of the piston rods of the two oil cylinders 31 are fixedly mounted with the same bottom plate 32, a vertical plate 33 is fixedly mounted on the top of the bottom plate 32, an oil cylinder 34 is fixedly mounted through the vertical plate 33, and a rotating disk 35 is rotatably mounted on the end of the piston rod of the oil cylinder 34.

[0034] A connecting shaft 65 is fixedly installed on the side of the circular plate 61 away from the distance adjusting mechanism 5, and a one-way bearing 67 is sleeved on the connecting shaft 65. A rotating ring 66 is sleeved on the one-way bearing 67. The rotating ring 66 includes an inner ring and an outer ring. The inner ring of the one-way bearing 67 is fixedly sleeved on the connecting shaft 65, and the outer ring of the one-way bearing 67 is fixedly connected to the inner wall of the rotating ring 66.

[0035] Furthermore, since the one-way bearing 2 67 can only rotate in one direction, when welding the bottle body 81 and the bottle mouth 82, the rotation of the bottle mouth 82 resting on the rotating ring 66 will drive the circular plate 2 61 to rotate synchronously. However, when polishing the bottle body 81 and the bottle mouth 82, since the circular plate 2 61 is locked and cannot rotate, the rotating ring 66 can only be driven by the bottle mouth 82 to rotate around the stationary connecting shaft 65.

[0036] In this embodiment: when in use, the hand wheel 644 is turned to drive the worm 643 to rotate, the worm 643 then drives the gear ring 642 to rotate, and the gear ring 642 then drives the second circular plate 61 to rotate around the rotating column 58. During the rotation of the second circular plate 61, as the positions of the multiple adjustment holes 611 change, the multiple circular shafts 62 will be pushed to gather or spread synchronously at the same time, and then the bottle mouth piece 82 is inserted between the multiple circular shafts 62, so that when the bottle mouth piece 82 is coaxial with the second circular plate 61, the multiple grinding columns 63 can fit tightly with the bottle mouth piece 82;

[0037] Then, the four oil cylinders 1 21 and the two oil cylinders 2 31 are controlled to extend and retract, so that when the bottle body 81 is at the top of the two power rollers 24, the bottle body 81 can be in a coaxial state with the rotating disk 35 and the circular plate 2 61. Then, the oil cylinder 3 34 is controlled to extend, and the oil cylinder 3 34 pushes the rotating disk 35 to abut against the bottom of the bottle body 81 while pushing the bottle mouth 82 to pass over the multiple cutters 631 and approach the bottle body 81. In this process, the bottle body 81 pushes the bottle mouth 82 to fit tightly with the rotating ring 66, and through the limiting of the multiple circular shafts 62, the connection between the bottle body 81 and the bottle mouth 82 will be tightly connected, and the bottle body 81 and the bottle mouth 82 will also be in a coaxial state and on the grinding column 63 on the upper circular shaft 62, and the connection between the bottle body 81 and the bottle mouth 82 is located in the middle of the other grinding columns 63;

[0038] Then, the two power rollers 24 are controlled to drive the bottle body 81 to rotate, and the bottle body 81 then drives the distance adjustment mechanism 5 and the various components on the variable diameter limit grinding assembly 6 except the cylinder 51 to rotate synchronously through the bottle mouth piece 82. During the rotation of the circular plate 1 52 around the cylinder 51, the plurality of prisms 53 and the rollers 54 will also rotate around the cylinder 51. When a roller 54 passes through the V-shaped groove 512, the roller 54 will pull the circular shaft 62 and the grinding column 63 toward the column 4 through the prism 53, the guide rail 55 and the slider 56. During this process, the grinding column 63 will be separated from the bottle mouth piece 82, so that the top of the connection between the bottle body 81 and the bottle mouth piece 82 is exposed without any shielding, so that the welding gun 7 can weld the exposed part.

[0039] When the roller 54 passes over the V-shaped groove 512, it will return to its original position. In the process of the grinding column 63 moving toward the distance adjustment mechanism 5, the weld scar of the fire extinguisher body 8 can be cut, so that the weld scar will not hinder the resetting of the grinding column 63. Then, the two power rollers 24 drive the bottle body 81 and the bottle mouth 82 to rotate in opposite directions. Since the one-way bearing 57 can only rotate in one direction, during the reverse rotation of the bottle body 81 and the bottle mouth 82, only the rotating ring 66 rotates on the distance adjustment mechanism 5 and the variable diameter limiting grinding assembly 6, and the other parts do not rotate. When the grinding columns 63 do not rotate, as the bottle body 81 and the bottle mouth 82 rotate, the grinding columns 63 can grind the weld scar at the connection between the bottle body 81 and the bottle mouth 82.

[0040] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
