In the description of this utility model, "a plurality of" means two or more, unless otherwise explicitly specified. Example

[0028] like Figure 1 As shown in the figure, this utility model provides a processing equipment for fire extinguisher bottle bodies, which has a processing table 1, wherein a support plate 2 is fixedly installed on the processing table 1, and three synchronously moving arc plates 21 are slidably connected on the end face of the support plate 2, and the outer wall of the arc plate 21 abuts against the inner circumferential surface of the bottle body plate.

[0029] The three arc plates 21 form an equilateral triangle, with the middle arc plate 21 located at the top. The lower part of the arc plate 21 is provided with a vertically movable support block 41. The top surface of the support block 41 is a concave arc surface that abuts against the bottom of the outer wall of the bottle body plate.

[0030] Optionally, in the above technical solution, a rotating rod 23 is fixedly installed on the right wall of the support plate 2, and three guide grooves 26 are provided on the support plate 2, which are equidistantly arranged in a ring along the rotating rod 23. Guide plates 27 are slidably connected in each guide groove 26, and the guide plates 27 are fixedly installed on the inner wall of the arc plate 21.

[0031] Optionally, in the above technical solution, a sleeve 24 is slidably connected to the rotating rod 23, and three side plates 25 corresponding to the guide plate 27 are fixedly installed on the sleeve 24. One end of a connecting rod 28 is hinged to both the front and rear ends of the side plate 25, and the other end of the connecting rod 28 is hinged to the guide plate 27.

[0032] Optionally, in the above technical solution, a screw 31 concentrically mounted on the right end of the rotating rod 23 is fixedly installed, and a screw block 32 is threadedly connected to the screw 31. The left wall of the screw block 32 is rotatably connected to the right wall of the sleeve 24 through a bearing.

[0033] Optionally, in the above technical solution, two mirror-symmetrical vertical plates 5 are fixedly installed on the processing table 1. The upper end of the vertical plate 5 is inclined, and an inclined plate 52 is fixedly installed on the top wall of the vertical plate 5 on the same side. The inclined plate 52 has multiple horizontally distributed threaded holes.

[0034] Optionally, in the above technical solution, the inclined plate 52 is threaded with a bolt 53, and a pressure block 51 is fixedly installed at the bottom end of the bolt 53.

[0035] During welding, the weld seam is located at the top, i.e., at the middle arc plate 21, and the two sides of the weld seam are held in place by pressure blocks 51. Furthermore, a relief groove 20 is provided on the top surface of the middle arc plate 21 to prevent sticking during welding and to facilitate heat dissipation.

[0036] When the distance between the sleeve 24 and the support plate 2 is the smallest, the angle between the connecting rod 28 and the support plate 2 is the smallest, and the arc plate 21 is located at the outermost end; when the distance between the sleeve 24 and the support plate 2 is the largest, the angle between the connecting rod 28 and the support plate 2 is the largest, and the arc plate 21 is located at the innermost end of the stroke; since the distance between the arc plate 21 and the rotating rod 23 is adjustable, the diameter of the circle formed by the arc plate 21 can be adjusted, which is convenient for welding operations of fire extinguisher cylinders of various sizes.

[0037] The two connecting rods 28 are spaced at the same distance from each other, and a counterweight is fixedly installed on the left wall of the support plate 2.

[0038] Furthermore, three rollers 33 are rotatably connected to the left and right side walls of the support plate 2. The rollers 33 are rotatably connected to the guide plate 27, so that the guide plate 27 and the arc plate 21 cannot move left or right, but can only move along the guide groove 26.

[0039] Furthermore, a telescopic cylinder 42 is fixedly installed on the processing table 1. The movable end of the telescopic cylinder 42 extends upward and is fixedly connected to both sides of the bottom wall of the support block 41. Preferably, the telescopic cylinder 42 is a cylinder with a guide rod. The telescopic cylinder 42 can be installed using existing equipment as needed, and the cylinder's lifting and lowering can be achieved through existing control elements and controllers such as solenoid valves and PLCs used to control cylinder lifting and lowering. Preferably, a thrust bearing is used between the screw block 32 and the sleeve 24.

[0040] Furthermore, a relief groove 20 is provided at the position corresponding to the welding joint to avoid the connection during welding and to serve as a heat dissipation function.

[0041] When in use, the rolled-up fire extinguisher bottle body plate is placed over the outside of the arc plate 21. The arc plate 21 can be moved to fit the inner diameter of the rolled-up plate before the plate is placed, or the plate can be placed first and then moved so that the outer wall of the arc plate 21 abuts against the inner wall of the plate. The support block 41 is moved up until the concave surface of the support block 41 contacts the outer wall of the plate. Then the bolt 53 is tightened so that the inner end of the bolt 53 contacts the outer wall of the support block 41.

[0042] At this time, the arc plate 21 and the support block 41 jointly support the plate, and the bolts 53 at both ends press down on both sides of the area to be welded to prevent displacement during welding and ensure that the plate remains in the rolled state.

[0043] The support block 41 moves as follows: the telescopic cylinder 42 is activated to extend or retract its movable end, thereby moving the support block 41 up and down.

[0044] The pressure block 51 moves by turning the bolt 53 so that it moves linearly along the fixed inclined plate 52, thereby moving the pressure block 51.

[0045] The movement of the arc plate 21 is as follows: the screw block 32 is rotated by the handle on the screw block 32. Since the rotating rod 23 is fixed on the support plate 2, the screw 31 cannot move. Therefore, the screw block 32 moves relative to the screw 31. The sleeve 24 is driven to slide linearly on the rotating rod 23 through the thrust bearing. Under the restriction of the guide groove 26 and the guide plate 27, the connecting rod 28 pushes the arc plate 21 to move inward or outward synchronously, so that the distance between the three arc plates 21 and the rotating rod 23 is always consistent. This method is applicable to rolled plates of various sizes.

[0046] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
