Description

Technical Field

[0001] The present invention relates to the technical field of water meter housing processing, and particularly to a precise welding platform for processing an adaptive metal housing of a water meter. Background Art

[0002] Most water meter housings are made of metal. During the processing, the two ends of the housing are usually welded to pipes. Therefore, a corresponding welding platform is needed to fix the water meter housing and the pipes connected thereto, so as to facilitate welding. For example, an electromagnetic water meter connecting pipe temporary welding device with the publication number CN217253911U includes a frame, a welding working part and a power part. The welding working part is arranged above the frame; the power part is arranged below the frame. The water meter body is placed upside down in the body fixing jig seat, and the two ends of the water meter are aligned with the bearings, so that the water meter body can roll on the bearings. Press the start switch, and the air cylinder starts. The contraction of the air cylinder will drive the fixed seat on the right side of the air cylinder to move to the left. At the same time, because the linear tooth rail is fixed on the fixed seat on the right side of the air cylinder, it will drive the connecting pipe fixing jigs on the left and right sides to move towards each other. Clamp the threaded connecting pipe and the water meter body together. Manually rotate the large disc to adjust the position of the temporary welding part. If the positions are not concentric, tap with a rubber hammer to adjust to the best position. By shortening the time for adjusting the concentricity of the water meter body and the connecting pipe, the production efficiency is improved. The occurrence of defective formal welding is reduced due to the improvement of the temporary welding quality; For example, a stainless steel water meter housing component welding device with the publication number CN114952163A. A stainless steel water meter housing component welding device that can fix objects and ensure welding quality is provided. It includes a base, a turntable, a support frame, a rotating shaft, a gear, a placement block, etc. A turntable is rotatably arranged on the upper side of the middle part of the base. Six support frames are evenly installed on the outer wall of the turntable along the circumference. The outer upper sides of the support frames are all rotatably and slidably provided with rotating shafts. Gears are installed at the lower parts of the rotating shafts. The outer upper sides of the support frames are all rotatably provided with placement blocks for placing the water meter housing. The pressing plate can cooperate with the placement block to clamp the water meter housing, so as to prevent the water meter housing from falling off the placement block during welding, and prevent the components of the water meter housing from separating during welding, thereby ensuring the welding quality. However, the above welding device still has the following disadvantages in actual use: 1. The traditional welding platform is not convenient to simultaneously fix the water meter housing and the pipe synchronously. It is necessary to fix the two separately, and the positions between the housing and the pipe need to be continuously adjusted during the fixing process, otherwise welding position deviation will occur; 2. At the same time, a large amount of heat and welding fume will be generated during the welding process. For the traditional welding platform, the treatment of heat and welding fume is not efficient enough, which will not only affect the welding stability, but also affect the processing environment.

[0003] In view of the above problems, it is urgent to innovate and design on the basis of the original welding platform. Summary of the Invention

[0004] The purpose of the present invention is to provide a precise welding platform for processing the metal shell of an adaptive water meter, so as to solve the problems in the above-mentioned background technology that the traditional welding platform is not convenient for synchronously fixing between the water meter shell and the pipeline at the same time, and the traditional welding platform is not efficient enough in dealing with heat and welding fumes.

[0005] To achieve the above purpose, the present invention provides the following technical solution: A precise welding platform for processing the metal shell of an adaptive water meter, which includes a processing table. The left end of the processing table is fixed with a support seat through a vertical rod, and adjustment plates penetrate through both the front and rear sides of the support seat. The top end of the adjustment plate is fixed with a limiting plate in an arc shape, and the limiting plate is used for clamping the outer shell of the water meter. It further includes: a motor, installed at the right end of the processing table. The output shaft of the motor is connected with a connecting shaft, and the connecting shaft is connected with one end of a transmission shaft through a pulley mechanism. The other end of the transmission shaft is fixed with a movable ring, and a welding torch is installed on the side of the movable ring away from the transmission shaft, and the welding head of the welding torch is located at the connection between the water meter outer shell and the pipeline. A cleaning mechanism is arranged on the side of the movable ring, and the cleaning mechanism is used for cleaning the dust at the welding position and the welding fumes generated during welding.

[0006] Preferably, the adjustment plate is in an "L" shape, and the adjustment plate is slidably connected with the support seat. The support seat is hollow inside, and the upper surface of the support seat is recessed. Fixing holes are reserved at the edge of the recess of the support seat, which is convenient for the bottom of the water meter shell to contact the recess of the support seat.

[0007] Preferably, a movable plate is fixed at the bottom end of the adjustment plate, and the edge of the movable plate fits and slides with the inner wall of the support seat. Springs are connected between the mutually remote sides of the two movable plates and the inner wall of the support seat. At the same time, a connecting rod is arranged on the mutually close sides of the two movable plates. When pulling the adjustment plate, the movable plate is driven to move inside the support seat, and the connecting rod is driven to rotate into an inclined state.

[0008] Preferably, fixing grooves are opened on the movable plates at both ends of the connecting rod, and both ends of the connecting rod rotate and slide in the fixing grooves. At the same time, a support shaft is fixedly penetrated through the middle of the connecting rod, and the support shaft is rotatably arranged in the support seat. When the connecting rod rotates, it can slide in the fixing groove, thereby realizing the movement of the two adjustment plates in opposite directions.

[0009] Preferably, the side of the support base is fixedly connected to one end of the infusion tube, and the other end of the infusion tube is connected to a support cylinder. The interior of the support base is interconnected with the interior of the support cylinder through the infusion tube. Meanwhile, the support cylinder is used to support the pipe connected to the water meter housing. When the two movable plates move away from each other, the liquid in the support cylinder can be pumped into the support base. When the two movable plates move closer to each other, the liquid in the support base can be pushed into the support cylinder.

[0010] Preferably, a through groove is formed on the outer side of the support cylinder, and a rubber sheet is pasted on the inner side of the through groove. The end of the support cylinder away from the infusion tube and the welding head of the welding torch are on the same vertical plane. Meanwhile, the infusion tube is sleeved outside the movable ring. When the interior of the support cylinder is filled with liquid, it can drive the rubber sheet to expand.

[0011] Preferably, the cleaning mechanism includes a fixed tube fixed to the movable ring. The feeding end of the fixed tube is close to the welding head of the welding torch. A fixed cavity is formed inside the movable ring. Meanwhile, a sleeve plate is sleeved outside the movable ring. Through the setting of the fixed tube, when gas is generated, the dust at the welding position can be cleaned, and when suction is generated, the welding fume can be sucked away.

[0012] Preferably, the sleeve plate and the movable ring are rotationally connected. The transmission shaft is in a "Z" shape, and the diameter of the pulley on the transmission shaft is larger than the diameter of the pulley on the connecting shaft. When the transmission shaft drives the movable ring to rotate, it can drive the welding torch to rotate synchronously.

[0013] Preferably, the fixed tube is internally connected to the interior of the connecting tube through the fixed cavity. The connecting tube is fixed between the sleeve plate and the fixed cylinder. The fixed cylinder is arranged on the upper end surface of the processing table. Meanwhile, a connecting shaft rotatably penetrates through the interior of the fixed cylinder. The sucked welding fume is transmitted into the connecting tube through the fixed cavity and then enters the fixed cylinder.

[0014] Preferably, a threaded groove is formed on the outer side of the connecting shaft, and the connecting shaft is in threaded connection with the piston plate. A fixing plate is fixed to one end of the fixed cylinder close to the connecting tube. The fixing plate is in a fan shape. A waste discharge pipe is arranged on the fixed cylinder on the side of the fixing plate. When the connecting shaft rotates, through the threaded transmission with the piston plate, the piston plate can be driven to move inside the fixed cylinder.

[0015] Compared with the prior art, the beneficial effects of the present invention are as follows: This precision welding platform for the adaptive metal housing processing of water meters facilitates the synchronous fixation between the water meter housing and the pipe, ensures the accurate stability of the position after fixation, thereby improving the precision of welding. Moreover, it can handle the heat and welding fume generated during welding, enhance the firmness after welding, and reduce the impact on the processing environment. The specific content is as follows: 1. Pull one of the adjusting plates. Through the rotation and sliding of the connecting rod, the two adjusting plates can be guided to move away from each other. Then, connect the bottom of the water meter housing to the concave part on the upper end face of the support seat. Release the pull on the adjusting plate. The resilience of the spring drives the two adjusting plates and the limiting plate to move closer to each other to achieve preliminary fixation of the water meter housing. When the movable plate moves inside the support seat, the gas is extruded from the fixed holes. When the movable plate returns to its original position, the gas between the water meter housing and the support seat can be pumped into its interior through the fixed holes, making the bottom of the water meter housing be adsorbed on the support seat under negative pressure to achieve secondary fixation and ensure the stability during welding. 2. When the two movable plates move away from each other, the negative pressure generated can pump the liquid in the support cylinder to the inside of the support seat through the infusion tube. In this way, the outside of the support cylinder is in a flat state, which is convenient for sleeving the pipeline outside it. When the two movable plates move closer to each other, the liquid in the support seat can be re-extruded into the support cylinder through the infusion tube. After the support cylinder is filled with liquid, it drives the rubber sheet to expand, which can support inside the pipeline to achieve stable positioning. Furthermore, during the welding process, the expanded rubber sheet contacts the welding position, and the liquid can be used to cool the welding position. 3. Through the threaded drive of the connecting shaft and the piston plate, when the piston plate moves to the right, the gas in the fixed cylinder can be extruded, and discharged from the fixed tube through the connecting pipe and the fixed cavity to blow towards the welding position to clean the dust at the welding position. When the piston plate moves to the left, suction can be generated to suck the welding fumes generated during welding from the fixed tube into the fixed cavity, and finally transmitted to the fixed cylinder through the connecting pipe and then discharged from the waste pipe.

Detailed implementation manners

[0018] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0019] Please refer to Figures 1-8 , the present invention provides the following technical solutions: Embodiment 1: To solve the problems existing in the prior art, therefore, in this embodiment, through the following technical solutions, a precise welding platform for processing the metal shell of an adaptive water meter includes a processing table 1. The left end of the processing table 1 is fixed with a support base 2 through a vertical rod, and adjusting plates 3 penetrate through the front and rear sides of the support base 2. The top of the adjusting plate 3 is fixed with a limiting plate 4 with an arc structure, and the limiting plate 4 is used for clamping the outer shell of the water meter; it further includes: a motor 13 installed at the right end of the processing table 1. The output shaft of the motor 13 is connected to a connecting shaft 14, and the connecting shaft 14 is connected to one end of a transmission shaft 15 through a pulley mechanism. The other end of the transmission shaft 15 is fixed with a movable ring 16, and a welding torch 17 is installed on the side of the movable ring 16 away from the transmission shaft 15, and the welding head position of the welding torch 17 is at the connection between the outer shell of the water meter and the pipeline; a cleaning mechanism is arranged on the side of the movable ring 16, and the cleaning mechanism is used for cleaning the dust at the welding position and the welding fume generated during welding.

[0020] The existing welding platform is not convenient for synchronously fixing the water meter shell and the pipeline at the same time. It is necessary to fix the two separately, and during the fixing process, it is necessary to continuously adjust the position between the shell and the pipeline, otherwise it will cause deviation of the welding position, such as Figures 1-4As shown in the figure, the adjusting plate 3 is in an "L" shape, and the adjusting plate 3 is slidably connected to the support base 2. The support base 2 is hollow inside, and the upper surface of the support base 2 is recessed. Fixing holes 201 are reserved at the edges of the recess of the support base 2. A movable plate 5 is fixed to the bottom end of the adjusting plate 3, and the edge of the movable plate 5 is in sliding contact with the inner wall of the support base 2. The two movable plates 5 are connected to the inner wall of the support base 2 by springs on the sides away from each other. At the same time, a connecting rod 6 is arranged on the side where the two movable plates 5 are close to each other. Fixing grooves 7 are formed in the movable plates 5 at both ends of the connecting rod 6, and both ends of the connecting rod 6 rotate and slide in the fixing grooves 7. A support shaft 8 is fixedly penetrated through the middle of the connecting rod 6, and the support shaft 8 is rotatably arranged in the support base 2. Before welding, pull one of the adjusting plates 3, which will drive the connecting rod 6 to rotate. At the same time, both ends of the connecting rod 6 slide in the fixing grooves 7. Through the guidance of the connecting rod 6, the two adjusting plates 3 can be moved away from each other. Then connect the bottom of the water meter housing to the recess on the upper end surface of the support base 2. Release the pulling force on the adjusting plate 3. The resilience of the spring drives the two adjusting plates 3 and the limiting plate 4 to move closer to each other and clamp the outside of the water meter housing to achieve preliminary fixation, and adaptively fit and limit according to the appearance of the water meter housing. When pulling the adjusting plate 3, the movable plate 5 can be driven to move inside the support base 2. When moving, the gas between the movable plate 5 and the support base 2 is extruded out through the fixing holes 201. When the movable plate 5 returns to its original position, the gas between the water meter housing and the support base 2 can be pumped into its interior through the fixing holes 201, making the bottom of the water meter housing be negatively pressured and adsorbed on the support base 2 to achieve secondary fixation and ensure the stability during welding.

[0021] Embodiment 2: The existing welding platform cannot dissipate the heat generated during welding in time, which will affect the welding stability. Therefore, this embodiment adopts the following technical solutions, such as Figures 2-6As shown in the figure, the side surface of the support base 2 is fixedly connected to one end of the infusion tube 9, and the other end of the infusion tube 9 is connected to a support cylinder 10. The inside of the support base 2 is interconnected with the inside of the support cylinder 10 through the infusion tube 9. At the same time, the support cylinder 10 is used to support the pipe connected to the water meter housing. A through groove 11 is provided on the outer side of the support cylinder 10, and a rubber sheet 12 is pasted on the inner side of the through groove 11. One end of the support cylinder 10 away from the infusion tube 9 is on the same vertical plane as the welding head of the welding torch 17. At the same time, the infusion tube 9 is sleeved outside the movable ring 16. When the two movable plates 5 move away from each other, the negative pressure generated can pump the liquid in the support cylinder 10 through the infusion tube 9 into the support base 2. In this way, the outside of the support cylinder 10 is in a flat state, which is convenient for sleeving the pipe connected to the water meter housing outside it. After the water meter housing is placed, when the two movable plates 5 move closer to each other, the liquid in the support base 2 can be squeezed back into the support cylinder 10 through the infusion tube 9. After the support cylinder 10 is filled with liquid, it drives the rubber sheet 12 to expand, so that it can support and achieve stable positioning inside the pipe, which is convenient for subsequent welding between the pipe and the water meter housing. At the same time, during the welding process, the expanded rubber sheet 12 contacts the welding position, and the liquid can be used to cool the welding position. Then, the motor 13 drives the connecting shaft 14 to rotate, drives the transmission shaft 15 to rotate through the transmission of the pulley mechanism. The transmission shaft 15 drives the movable ring 16 and the welding torch 17 to rotate and revolve around the welding position to achieve full welding.

[0022] Embodiment 3: The traditional welding platform is not efficient enough in heat treatment and affects the processing environment. Therefore, this embodiment adopts the following technical solutions, such as Figures 6-8As shown in the figure, the cleaning mechanism includes a fixed pipe 18 fixed to the movable ring 16. The feeding end of the fixed pipe 18 is close to the welding head position of the welding torch 17. A fixed cavity 19 is provided inside the movable ring 16. At the same time, a sleeve plate 20 is sleeved outside the movable ring 16. The sleeve plate 20 and the movable ring 16 are rotatably connected. The transmission shaft 15 is of a "Z" - shaped structure, and the diameter of the pulley on the transmission shaft 15 is larger than the diameter of the pulley on the connecting shaft 14. The fixed pipe 18 is internally connected to the inside of the connecting pipe 21 through the fixed cavity 19. The connecting pipe 21 is fixed between the sleeve plate 20 and the fixed cylinder 22. The fixed cylinder 22 is arranged on the upper end surface of the processing table 1. At the same time, the connecting shaft 14 rotatably penetrates through the inside of the fixed cylinder 22. A threaded groove is provided on the outside of the connecting shaft 14, and the connecting shaft 14 is threadedly connected to the piston plate 23. A convex block that slides with the inner wall of the fixed cylinder 22 is provided at the edge of the piston plate 23. A fixed plate 24 is fixed at one end of the fixed cylinder 22 close to the connecting pipe 21. The fixed plate 24 is of a sector structure. A waste discharge pipe 25 is provided on the fixed cylinder 22 at the side of the fixed plate 24. When the connecting shaft 14 rotates, through the threaded drive with the piston plate 23, the piston plate 23 can move inside the fixed cylinder 22. When the piston plate 23 moves to the right, the gas inside the fixed cylinder 22 can be extruded out, and is transmitted to the fixed cavity 19 through the connecting pipe 21, and finally discharged from the fixed pipe 18 and blown towards the welding position to clean the dust at the welding position. When the motor 13 drives in the other direction, the welding torch 17 works, and the piston plate 23 moves to the left, generating suction, sucking the welding fume generated during welding from the fixed pipe 18 into the fixed cavity 19, and finally transmitting it to the fixed cylinder 22 through the connecting pipe 21, and then discharging it from the waste discharge pipe 25. When the movable ring 16 drives the welding torch 17 to rotate, the sleeve plate 20 remains stationary, which neither affects welding nor can realize the transmission of gas.

Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
