Description

Technical Field

[0001] This utility model relates to the technical field of fire extinguisher bottle welding equipment, and in particular to a rotary table type dual-position valve laser welding device. Background Technology

[0002] Fire extinguisher cylinders are typically welded together from steel pipes, an upper end cap, a valve, and a base. When welding the upper end cap and valve, workers usually place the upper end cap on a rotating seat, then manually place the valve onto the upper end cap, and finally weld them together using argon arc welding or laser welding. Because manual welding inevitably leads to inconsistent quality of fire extinguisher cylinders, automated welding equipment is now widely used. Existing laser welding equipment usually only welds one fire extinguisher cylinder at a time. During welding, workers must wait for the cylinder on the machine to be welded before removing it and replacing it with the next one. This undoubtedly increases working time and affects production efficiency. Therefore, a welding device that can improve production efficiency is needed to increase the welding efficiency of the upper end cap and valve. Utility Model Content

[0015] The present invention will be described in detail below with reference to specific embodiments.

[0016] In this utility model, unless otherwise explicitly specified and limited, when terms such as "set in," "connected," or "linked" appear, these terms should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or a connection through one or more intermediate media. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances. The directional terms appearing in this utility model are for the purpose of better describing the characteristics of the features and the relationships between them. It should be understood that when the placement direction of this utility model changes, the direction of the characteristics of the features and the relationships between them also changes accordingly. Therefore, directional terms do not constitute an absolute limitation on the characteristics of the features and the relationships between them in space, but only a relative limitation.

[0017] like Figures 1 to 3 As shown, this utility model provides a rotary table type dual-position valve laser welding device, including a frame 1, on which a welding component 2 and a support component 3 are provided. The support component 3 is used to place the upper end cap and the valve position, and the welding component 2 is used to weld the end cap and the valve position on the support component 3. The supporting component 3 includes a rotating disk 31, a lifting cylinder 34, a support base 32, a workpiece rotation reduction motor 35, and a positioning rod 36. The rotating disk 31 is mounted on the frame 1, and multiple sets of support bases 32 are evenly arranged on the rotating disk 31. The support bases 32 are used to place the upper end cap. The lifting cylinder 34 is fixedly mounted on the frame 1, and the lifting cylinder 34 is located directly below the support base 32. The workpiece rotation reduction motor 35 is fixedly mounted on the frame 1, and the positioning rod 36 is mounted below the workpiece rotation reduction motor 35. The central axis of the positioning rod 36 coincides with the central axis of the lifting cylinder 34, and the positioning rod 36 is located above the support base 32.

[0018] With the above design, the support base 32 is used to place the upper end cap and the valve position. The lifting cylinder 34 on the frame 1 can lift the upper end cap and the valve position, so that the valve position presses against the positioning rod 36. During welding, the workpiece rotation reduction motor 35 will drive the valve position and the upper end cap to rotate through the positioning rod 36, so that the weld between the valve position and the upper end cap is more uniform.

[0019] In this embodiment, a worktable rotary reduction motor 30 is provided at the bottom of the frame 1, which drives the rotary disk 31 to rotate. The rotary disk 31 is provided with a workpiece placement position 311, a welding workpiece position 310, and a workpiece removal position 312. Each of the workpiece placement position 311, the welding workpiece position 310, and the workpiece removal position 312 is provided with two support bases 32. Each support base 32 is provided with a feeding tray 33, and the feeding tray 33 is slidably connected to the support base 32. The lifting cylinder 34 and the positioning rod 36 are both located in the welding workpiece position 310.

[0020] Through the above design scheme, different workstations can perform different tasks simultaneously. The worker places the upper end cap and valve position to be welded onto the material trays 33 of the two support bases 32 in the workpiece placement position 311. The worktable rotation reduction motor 30 drives the rotating disk 31 to rotate, and the support bases 32 in the workpiece placement position 311 are transferred to the welding workpiece position 310 for automatic welding. At the same time, the support bases 32 that were originally in the welding workpiece position 310 will be transferred to the workpiece removal position 312 with the welded upper end cap and valve position, waiting for the material discharge component 5 described below to automatically transfer the welded valve position and upper end cap to the pre-placed material frame or conveyor belt. The empty support bases 32 will be driven by the rotating disk 31 to return to the workpiece placement position 311, and the worker will continue to place the parts.

[0021] When the rotating disk 31 moves the valve position and the upper end cap to be welded to the welding workpiece position 310, the lifting cylinder 34 lifts the material discharge disk 33 with the valve position and the upper end cap until the valve position and the upper end cap are tightly clamped between the material discharge disk 33 and the positioning rod 36; after the welding work is completed, the lifting cylinder 34 lowers, and the material discharge disk 33 automatically descends under the action of gravity to avoid the positioning rod 36 affecting the normal rotation of the rotating disk 31.

[0022] In this embodiment, a discharge assembly 5 is provided on the frame 1 and is located in the workpiece pick-up position 312. The discharge assembly 5 includes a discharge clamp 55, a discharge cylinder 54, a discharge lifting movable beam 53, a discharge transverse movable beam 52, a discharge lifting cylinder 51, and a discharge transverse movable cylinder 50. The discharge transverse movable cylinder 50 is mounted on the frame 1. The extension end of the discharge transverse movable cylinder 50 is equipped with the discharge transverse movable beam 52. The discharge lifting cylinder 51 is provided on the discharge transverse movable beam 52. The extension end of the discharge lifting cylinder 51 is equipped with the discharge lifting movable beam 53. The discharge cylinder 54 is provided on the discharge lifting movable beam 53. The discharge cylinder 54 is used to drive the discharge clamp 55 to clamp or release.

[0023] Through the above design scheme, the discharge component 5 can automatically clamp the welded upper end cap and valve position and transfer them to the pre-placed material frame on one side for easy collection or entry into the next process. The welded upper end cap and valve position are transferred from the welding workpiece position 310 to the workpiece removal position 312. When the detector in the workpiece removal position 312 detects the upper end cap and valve position, the discharge lifting cylinder 51 drives the discharge clamp 55 to descend. At the same time, the discharge cylinder 54 controls the discharge clamp 55 to open and clamp the valve position. Then the discharge lifting cylinder 51 retracts, clamping the welded upper end cap and valve position from the discharge plate 33. After the upper end cap and valve position are raised to the appropriate height, the discharge transverse cylinder 50 is activated, moving the raised upper end cap and valve position away from the discharge plate 33 and transferring them to the pre-placed material frame or conveyor belt, completing the automatic unloading operation.

[0024] In this embodiment, a lifting guide rail is provided on the discharge lifting movable beam 53, and the lifting guide rail is slidably connected to the discharge transverse movable beam 52. The lifting guide rail can improve the smoothness of the discharge lifting movable beam 53, making the movement of the discharge lifting movable beam 53 more stable and smooth.

[0025] In this embodiment, the welding assembly 2 includes a laser welding gun 20, a welding gun position adjustment unit 21, a wire feeder 22, and a wire feed spool 23. The laser welding gun 20 is mounted on the frame 1 via the welding gun position adjustment unit 21, and the wire feeder 22 and the wire feed spool 23 are both mounted on the frame 1. The laser welding gun 20 is provided with a wire feeding nozzle 26, which is connected to the wire feeder 22 and the wire feed spool 23 in sequence.

[0026] With the above design, the user can adjust the position of the laser welding gun 20 through the welding gun position adjustment unit 21, so that the laser welding gun 20 is aligned with the connection part between the upper end cap and the valve position in the workpiece position 310; the wire feed tray 23 is used to place the welding wire, and the welding wire comes from the wire feed tray 23 to the wire feed nozzle 26 under the drive of the wire feeder 22, and is then transported to the connection part between the upper end cap and the valve position through the wire feed nozzle 26 to participate in the welding work.

[0027] In this embodiment, a chiller 24 and a laser generator 25 are mounted on the frame 1. The laser generator 25 is installed at the bottom of the frame 1, and the chiller 24 is installed at the top of the frame 1. The chiller 24 and the laser generator 25 are existing technologies and are not the improvement points of this embodiment, therefore they are not described in detail in this embodiment.

[0028] In this embodiment, the welding torch position adjustment unit 21 includes a lifting guide rail module, an inclined platform, a horizontal guide rail module, and a vertical guide rail module. The lifting guide rail module is fixedly installed on the frame 1. The inclined platform is slidably connected to the lifting guide rail module. The horizontal guide rail module is fixedly installed on the inclined platform. The vertical guide rail module is slidably connected to the horizontal guide rail module. The laser welding torch 20 is slidably connected to the vertical guide rail module.

[0029] The lifting guide rail module, tilting platform, horizontal guide rail module and vertical guide rail module are existing technologies and are not the improvement points of this embodiment, so they are not described in this embodiment.

[0030] In this embodiment, a dust collection and filter processor 4 is installed on the frame 1, and a dust collection nozzle 40 is installed on the dust collection and filter processor 4, which is close to the positioning top rod 36. The dust collection and filter processor 4 can absorb the fumes generated during laser welding, reducing the impact of welding fumes on the health of workers.

[0031] The rotary table type dual-position valve laser welding device provided by this utility model, compared with the prior art, has a support base 32 on the rotary disk 31 that repeatedly alternates between the workpiece placement position 311, the workpiece welding position 310, and the workpiece removal position 312. The upper end cap and valve position to be welded are transferred from the workpiece placement position 311 to the workpiece welding position 310 for welding, and then transferred to the workpiece removal position 312, where the welded upper end cap and valve position are removed by the material discharge component 5. The worker only needs to perform the workpiece placement, and the welding and material discharge can be carried out simultaneously during the workpiece placement, thereby improving the welding efficiency of the upper end cap and valve position.
