Description

Technical Field

[0001] This utility model relates to the field of steel cylinder welding technology, specifically an automatic welding equipment for fire extinguisher cylinders. Background Technology

[0002] Fire extinguisher cylinders are one of the main components of fire extinguishers. In the production of extinguishing agent steel sheets, welding is usually required. To weld a fire extinguisher cylinder, the existing technology is for the operator to first manually assemble the upper end cap, lower end cap, and cylinder body together, place them on a rotating table for clamping and positioning, and then perform welding.

[0003] Currently, some automated welding equipment requires manual adjustment of the cylinder's position after it is placed in front of the clamping frame. The cylinder can only be released after the clamping limit is reached. In addition, the clamping structure on the rotary table is mostly adapted to the cylinder models currently being produced, and there is room for improvement in its applicability. Utility Model Content

[0004] The purpose of this invention is to provide an automatic welding device for fire extinguisher cylinders to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: An automatic welding device for fire extinguisher cylinders includes: A cylinder clamp includes a support frame, on which base plates are fixedly installed at both ends of the upper side of the support frame. A bottle bottom chuck is movably installed above one base plate, and a bottle mouth chuck is rotatably installed above the other base plate. The feeding structure includes a right-angle bracket, which is slidably installed between two sets of substrates at a 15-degree angle. The welded structure is fixedly installed above the cylinder clamp.

[0006] Furthermore, an electric actuator is fixedly installed on the upper part of the substrate on one side via a shaft bracket. A clamping plate is rotatably mounted on the output end of the electric actuator via a bearing. The clamping plate is fixedly engaged with the bottle bottom clamping plate by bolts.

[0007] Furthermore, a rotating shaft is rotatably mounted on the upper part of the substrate on the other side via a shaft bracket. One end of the rotating shaft is rotatably mounted with a snap-fit ​​end via a bearing. The snap-fit ​​end is fixedly snapped against the bottle mouth chuck by bolts. A drive motor is fixedly mounted on one side of the substrate on this side. The drive motor is linked to the rotating shaft via a synchronous sprocket set.

[0008] Furthermore, a first limiting side plate is fixedly installed on the inner edge of the bottom of the substrate, and a second limiting side plate is fixedly installed on the inner edge of the upper surface of the substrate. The first limiting side plate, the second limiting side plate, and the inner surface of the substrate are provided with a continuous limiting groove.

[0009] Furthermore, the limiting groove and the limiting slider are slidably engaged, the limiting slider is fixedly installed at both ends of the right-angle bracket corner, the back center of the right-angle bracket corner is fixedly connected to the output end of the second electric push rod, the electric pole mounting bracket is fixedly installed at the rear center of the support frame, and the electric pole mounting bracket is fixedly connected to the lower end of the second electric push rod and pushed by the bottle bottom chuck at the right-angle bracket corner.

[0010] Furthermore, the welded structure includes: An overhead support frame is fixedly installed on the upper side of the base plate; A linear motor, the two ends of which are fixedly connected to two sets of overhead support frames; The third electric actuator is fixedly installed at the slider of the linear motor. The welding head is fixedly installed at the output end of the No. 3 electric actuator.

[0011] Compared with the prior art, the beneficial effects of this utility model are: 1. Directly place the interlocked fire extinguisher cylinders onto the upper surface of the right-angle bracket, keeping the bracket at a constant tilt angle. Move the bracket diagonally upwards along the line connecting the corner of the right-angle bracket to the center lines of the bottom and top clamps, forcing the center line of the fire extinguisher cylinder to overlap with the center lines of the bottom and top clamps. The bottom clamp moves laterally, and the top clamps hold both ends of the fire extinguisher cylinder in place, facilitating welding work. The system features automatic feeding, eliminating the need for manual adjustment before positioning and adapting to various fire extinguisher cylinder structures.

[0012] 2. During operation, the bottom chuck is moved laterally by the No. 1 electric actuator, which then engages the two ends of the fire extinguisher bottle with the bottom chuck and the mouth chuck respectively for clamping and limiting. The drive motor, driven by the synchronous sprocket set, rotates the mouth chuck, thereby rotating the clamped fire extinguisher bottle, changing the welding point, and realizing the welding work.

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0016] Please see Figure 1-6 In this embodiment of the utility model, an automatic welding device for fire extinguisher cylinders includes a cylinder clamp 1, a feeding structure 2, and a welding structure 3. It includes a support frame 101, with base plates 102 fixedly installed at both ends of the upper side of the support frame 101. A bottle bottom chuck 106 is movably installed above one base plate 102, and a bottle mouth chuck 109 is rotatably installed above the other base plate 102. It also includes a right-angle bracket 205, which is slidably installed at a 15-degree angle between the two sets of base plates 102. It is fixedly installed above the cylinder clamp 1.

[0017] Specifically, the fire extinguisher cylinders, which are interlocked, are placed directly onto the upper surface of the right-angle bracket 205. The right-angle bracket 205 maintains its tilt angle and moves diagonally upward along the line connecting the corner of the right-angle bracket 205 with the center lines of the bottom chuck 106 and the top chuck 109. This forces the center line of the fire extinguisher cylinder to overlap with the center lines of the bottom chuck 106 and the top chuck 109. The lateral movement of the bottom chuck 106 and the top chuck 109 then lock the two ends of the fire extinguisher cylinder for positioning, facilitating welding of the welding structure 3. The system has an automatic feeding function, eliminating the need for manual adjustment before positioning and adapting to various types of fire extinguisher cylinder structures.

[0018] Example 1 like Figure 1 , 5 As shown, in this embodiment, a first limiting side plate 201 is fixedly installed on the inner edge of the bottom of the substrate 102, and a second limiting side plate 202 is fixedly installed on the inner edge of the upper surface of the substrate 102. A continuous limiting groove 203 is formed on the first limiting side plate 201, the second limiting side plate 202 and the inner surface of the substrate 102. The limiting groove 203 is slidably engaged with the limiting slider 204. The limiting slider 204 is fixedly installed at both ends of the right angle bracket 205. The middle part of the back of the right angle bracket 205 is fixedly connected to the output end of the second electric actuator 206. A pole mounting bracket 207 is fixedly installed on the middle part of the rear side of the support frame 101. The pole mounting bracket 207 is fixedly connected to the lower end of the second electric actuator 206.

[0019] In this embodiment, the right-angle bracket 205 is pushed by the bottom chuck 106 to the corner. Under the limiting guidance of the limiting slide 203 and the limiting slider 204, it gradually approaches the center line of the bottom chuck 106 and the bottle mouth chuck 109. The position of the fire extinguisher bottle is automatically adjusted by its tilted and right-angled structure, and automatic feeding is achieved.

[0020] like Figure 1 , 6 As shown, in this embodiment, the welding structure 3 includes an overhead support frame 301, a linear motor 302, a third electric actuator 303, and a welding head 304. The overhead support frame 301 is fixedly installed on the upper side of the base plate 102; the two ends of the linear motor 302 are fixedly connected to two sets of overhead support frames 301; the third electric actuator 303 is fixedly installed at the slider of the linear motor 302; and the welding head 304 is fixedly installed at the output end of the third electric actuator 303.

[0021] In practice, the linear motor 302 drives the third electric actuator 303 to move laterally, and the third electric actuator 303 drives the welding head 304 to move up and down. At the same time, the welding head 304 always points to the center line of the bottle bottom chuck 106 and the bottle mouth chuck 109, which can change the position of the welding point and can be adjusted according to the actual weld position of the processed fire extinguisher bottle, thereby further improving the adaptability of the processed fire extinguisher bottle models.

[0022] Example 2 Based on Embodiment 1, in order to supplement the specific method of clamping and limiting the fire extinguisher cylinder by the bottle bottom chuck 106 and the bottle mouth chuck 109, which was not mentioned in Embodiment 1.

[0023] like Figure 1-4As shown, in this embodiment, a first electric actuator 104 is fixedly installed on the top of one side of the substrate 102 via a shaft bracket 103. A clamping plate 105 is rotatably installed on the output end of the first electric actuator 104 via a bearing. The clamping plate 105 is fixedly engaged with the bottle bottom clamping plate 106 via bolts. A rotating shaft 107 is rotatably installed on the top of the other side of the substrate 102 via a shaft bracket 103. A clamping end 108 is rotatably installed on one end of the rotating shaft 107 via a bearing. The clamping end 108 is fixedly engaged with the bottle mouth clamping plate 109 via bolts. A drive motor 110 is fixedly installed on one side of the substrate 102. The drive motor 110 is linked to the rotating shaft 107 via a synchronous sprocket set 111.

[0024] In practice, the first electric actuator 104 pushes the bottom chuck 106 to move laterally, thereby clamping the two ends of the fire extinguisher bottle with the bottom chuck 106 and the mouth chuck 109 respectively for clamping and limiting. Then, the drive motor 110, driven by the synchronous sprocket set 111, drives the mouth chuck 109 to rotate, thereby rotating the clamped fire extinguisher bottle, changing the welding point, and realizing the welding work. At the same time, both the bottom chuck 106 and the mouth chuck 109 are replaceable. The corresponding bottom chuck 106 and mouth chuck 109 can be replaced according to the model of the fire extinguisher bottle to be welded, further improving the processing adaptability.
