Description

Technical Field

[0001] The invention relates to the technical field of welding processing, in particular to a fire extinguisher head welding tool. Background Art

[0002] A fire extinguisher is a portable fire-fighting tool. By placing chemicals in the fire extinguisher, it can be used to put out a fire. Fire extinguishers can be divided into portable fire extinguishers and trolley-type fire extinguishers according to their mobility. They have the advantages of fast fire-fighting speed, light weight, easy use, flexibility, safety and reliability. When manufacturing a portable fire extinguisher, the cylinder and the head of the portable fire extinguisher are fitted together, and then the cylinder and the head of the portable fire extinguisher are welded by a welding torch. In order to ensure stability during the welding process, welding tools are usually required to clamp and fix the cylinder and the head of the portable fire extinguisher to ensure the accuracy of the welding position and reduce the probability of incorrect or missed welding.

[0003] After welding is completed, the existing welding tooling needs to be transferred to a detection device to detect the weld. If the worker finds incorrect or missing welding, he needs to place the portable fire extinguisher on the welding tooling again for repair welding, which reduces production efficiency. In addition, when the tooling is in use, most of them will not provide support for its inner wall. During the welding process, the barrel body and the head may be deformed due to the force, resulting in incorrect or missing welding.

[0004] Therefore, in view of this, the existing structure and defects are studied and improved, and a fire extinguisher head welding tool is proposed. Summary of the invention

[0009] Furthermore, the support assembly also includes a connecting rod, a support plate and a connecting rod. The top rod and the support rod are symmetrically connected to the connecting rod on all sides, and the other end of the connecting rod is rotatably connected to the support plate. The top rod is connected to the connecting rod at one end close to the support rod, and the connecting rod is slidably connected to the support rod.

[0010] Furthermore, the support plate surface is symmetrically provided with sliding grooves, and a sliding seat is snap-connected in the sliding groove, one side of the sliding seat is connected to an axle seat, and a clamping roller is rotatably connected between the axle seats, and one end of the telescopic rod on the support plate on the other side of the base frame is connected to a suction cup.

[0011] Furthermore, the slide seat is slidably connected to the support plate via a slide groove, and there are four slide grooves equidistantly distributed on the support plate, and the axes of the slide grooves intersect at the center point of the support plate.

[0012] Furthermore, a dual-axis motor is connected to the rear side of the base frame, and screw rods are symmetrically connected to both sides of the dual-axis motor, and limit rods are symmetrically connected to the periphery of the base frame.

[0013] Furthermore, the outer side of the screw rod is threadedly connected to a frame, and a slide rail is provided on the surface of the frame. A slider is slidably engaged in the slide rail, and the slider is connected to the shaft seat. The frame is slidably engaged with the limit rod.

[0014] Furthermore, a lifting rod is symmetrically connected to the middle of the base frame, and the other end of the lifting rod is connected to a top material plate. A through opening is opened in the middle of the top material plate, and a rotating wheel is arranged in the through opening. A rotating motor is connected to one side of the rotating wheel.

[0015] Furthermore, adjustment grooves are symmetrically provided on both sides of the top material plate, and an adjustment plate is slidably connected in the adjustment groove, a scraper is connected to one side of the adjustment plate, and a groove is provided in the middle of the adjustment plate, and a grinding plate is slidably connected in the groove.

[0017] 1. When placing materials, the present invention can press the barrel bottom and the head tightly against the barrel body through the suction cup and the sealing plug as the telescopic rod moves, so as to avoid the occurrence of wrong or missed welding caused by too large a gap. When placing materials, the support assembly at the head can be adjusted by rotating the ventilation pipe in the ventilation groove to ensure that support can be provided for the connection between the barrel body and the welding head to avoid deformation due to force. After welding is completed, detergent is applied to the welding point, and then the air pump is started, so that the outside air can be drawn in from the air inlet groove, and then sent into the ventilation pipe from the ventilation groove, and injected into the shell through the ventilation hole. If there is a wrong or missed welding at the welding point, bubbles will be generated there, which is convenient for the staff to find the wrong or missed welding point and deal with it directly, saving the time of material transportation and improving the processing efficiency. If no bubbles appear, it means that the welding is complete and the material can be unloaded directly. In summary, when in use, the shell of the fire extinguisher can be inspected immediately after the welding is completed, without transferring it to the detection device for detection of the welding point, which is convenient for dealing with the wrong or missed welding point.

[0018] 2. Before welding, the present invention can rotate the adjusting rod in the sleeve according to the model of the fire extinguisher to adjust the support assembly at the bottom of the barrel to ensure that support can be provided for the connection between the barrel body and the barrel bottom to avoid deformation due to stress. When the material is placed and the barrel bottom and the head are pressed against the barrel body, as the telescopic rod moves, the top rod close to the barrel bottom is subjected to stress after contacting the barrel bottom, so that the two top rods respectively drive the connecting rod connected thereto to slide on the inner side of the support rod, and compress the buffer spring, so that the top rod cooperates with the support rod to make the connecting rod rotate on the top rod and the support rod, and the support plate is expanded outward and pressed against the inner wall of the connection between the barrel body and the barrel bottom and the head respectively to provide support for it, so as to avoid deformation of the material due to excessive stress caused by the clamping and fixing of the material during welding, thereby avoiding the occurrence of wrong or missed welding. In summary, when in use, support can be provided for the welding joints of different types of fire extinguishers during welding to avoid wrong or missed welding caused by deformation due to stress.

[0019] 3. When the present invention is in use, after placing the material, the lifting rod can first drive the lifting plate to rise and lift the material, and at the same time the double-axis motor drives the screw to rotate, so that the screw drives the frame to move in the direction of the material, and the limit rod can limit the frame to prevent the frame from deflecting during movement. During the movement of the frame, the slider can drive the shaft seat to move, and the slide groove can limit the shaft seat through the slide seat, so that the shaft seat drives the clamping roller along the slide groove to approach the material, so that the clamping roller positions and clamps the material, and the slider can limit the shaft seat through the slide rail to prevent the shaft seat from deflecting during movement. When welding the material, the rotating motor is started, which can make the wheel rotate in the through port, thereby driving the material to rotate through friction, which is convenient for welding the connection. At this time, the material can pass through the support group The parts drive the seal to rotate on the turn plate to prevent the material from driving the adjusting rod or the vent pipe to rotate in the sleeve or the vent groove through the support component, causing the support component to be displaced and causing welding failure. The clamping roller can also assist the material to rotate when clamping the material. In the welding process, as the material rotates, the scraper can immediately clean the weld scar formed by welding. At the same time, the grinding plate can grind the welding point to ensure the smoothness of the welding point. After the grinding plate fails, it only needs to slide it out of the slot and insert a new grinding plate to continue grinding the subsequent materials. It is convenient and quick. In summary, when in use, different types of materials can be clamped and the welding process can be assisted. After the welding is completed, the weld scar generated during welding can be processed immediately, which simplifies the processing process and improves the processing efficiency.

When the material is placed and the barrel bottom and the head are pressed tightly against the barrel body, as the telescopic rod 3 moves, the top rod 703 close to the bottom of the barrel contacts the bottom of the barrel and is stressed, so that the two top rods 703 respectively drive the connecting rod 706 connected thereto to slide inside the support rod 701 and compress the buffer spring 702, thereby The top rod 703 cooperates with the support rod 701 to make the connecting rod 704 rotate on the top rod 703 and the support rod 701, expand the support plate outward and press it against the inner wall of the connection between the barrel body and the barrel bottom and the head respectively, to provide support for it, to avoid deformation of the material due to excessive force caused by clamping and fixing the material during welding, thereby avoiding the occurrence of wrong or missing welding. In summary, when in use, support can be provided for the welding points of different types of fire extinguishers during the welding process, to avoid deformation caused by force and causing wrong or missing welding.

[0032] The specific operation is as follows. When in use, after the material is placed, the lifting rod 19 can first drive the ejecting plate 20 to rise and lift the material, and at the same time the dual-axis motor 13 drives the screw rod 14 to rotate, so that the screw rod 14 drives the frame 16 to move in the direction of the material, and the limit rod 15 can limit the frame 16 to prevent the frame 16 from deflecting during movement.

When welding the material, the rotating motor 23 is started, so that the wheel 22 can be rotated in the through port 21, thereby driving the material to rotate through friction, which is convenient for welding the connection. At this time, the material can drive the sealing plug 402 to rotate on the rotating plate 401 through the supporting assembly 7, so as to prevent the material from driving the adjusting rod 6 or the vent pipe 406 to rotate in the sleeve 5 or the vent groove 405 through the supporting assembly 7, causing the supporting assembly 7 to be displaced and causing welding failure. The clamping roller 11 can also assist the material to rotate when clamping the material. In the welding process, as the material rotates, the scraper 26 can immediately clean the weld scar formed by welding. At the same time, the grinding plate 28 can grind the welding point to ensure that the welding point is smooth. After the grinding plate 28 fails, it only needs to slide it out of the slot 27 and insert a new grinding plate 28 to continue grinding the subsequent materials. It is convenient and quick. In summary, when in use, different types of materials can be clamped and the welding process can be assisted. After the welding is completed, the weld scar generated during welding can be processed immediately, which simplifies the processing process and improves the processing efficiency.

[0033] In summary, when using this fire extinguisher head welding tool, first before welding, the adjusting rod 6 can be rotated in the sleeve 5 according to the model of the fire extinguisher, and the support component 7 at the bottom of the barrel can be adjusted to ensure that support can be provided for the connection between the barrel body and the barrel bottom. At the same time, the ventilation pipe 406 is rotated in the ventilation groove 405, and the support component 7 at the head can be adjusted to ensure that support can be provided for the connection between the barrel body and the welding head to avoid deformation due to force. Then the head and the barrel body are successively passed through the ventilation pipe 406 and the sleeve 5, and the bottom of the barrel is adsorbed on the suction cup 12. After the material is placed, the lifting rod 19 can first drive the top plate 20 to rise to lift the material, and at the same time the dual-axis motor 13 drives the screw rod 14 to rotate, so that the screw rod 14 drives the frame 16 towards the direction of the material. The frame 16 is moved to the right, the limit rod 15 can limit the frame 16 to prevent the frame 16 from deflecting during movement. During the movement of the frame 16, the slider 18 can drive the shaft seat 10 to move, and the slide 8 can limit the shaft seat 10 through the slide seat 9, so that the shaft seat 10 drives the clamping roller 11 to approach the material along the slide 8, so that the clamping roller 11 positions and clamps the material, and the slider 18 can limit the shaft seat 10 through the slide rail 17 to prevent the shaft seat 10 from deflecting during movement. Then the telescopic rod 3 moves, and the barrel bottom and the head are pressed against the barrel body through the suction cup 12 and the sealing plug 402 to prevent the gap from being too large and causing the wrong welding. As the telescopic rod 3 moves, the top rod 703 close to the barrel bottom contacts the barrel bottom and is subjected to force, so that the two top rods 70 3 respectively drive the connecting rod 706 connected thereto to slide inside the support rod 701, and compress the buffer spring 702, so that the top rod 703 cooperates with the support rod 701 to make the connecting rod 704 rotate on the top rod 703 and the support rod 701, expand the support plate outward and press it against the inner wall of the connection between the barrel body and the barrel bottom and the head, respectively, to provide support for it, so as to avoid deformation of the material due to excessive force caused by the clamping and fixing of the material when welding the material, thereby avoiding the situation of wrong welding.

The clamping roller 11 can also assist the material to rotate when clamping the material. In the welding process, as the material rotates, the scraper 26 can immediately clean the weld scar formed by welding. At the same time, the grinding plate 28 can grind the welding place to ensure the smoothness of the welding place. After the grinding plate 28 fails, it only needs to slide it out of the card slot 27 and insert a new grinding plate 28, and then the subsequent materials can be ground. It is convenient and quick. After the welding is completed, detergent is applied to the welding place, and then the air pump 403 is started to draw the outside air in from the air inlet groove 404.Then it is sent into the ventilation pipe 406 from the ventilation groove 405 and injected into the shell through the ventilation hole 407. If there is a wrong or missed welding at the welding place, bubbles will be generated there, which is convenient for the staff to find the wrong or missed welding place and deal with it directly, saving the time of material transportation and improving the processing efficiency. If no bubbles appear, it means that the welding is complete and the material can be unloaded directly.
